Revision of the S]»ecies of TROX of the United States.

BY GEO. H. HORN, M. D.

In the nintli and tenth parts of the Coleopterologische Hefte (Mu-
nich, 1872), Harold has published an elaborate monograph of the
species of Trox, in which ninety-three species are fully described from
the entire globe, fifteen remain unknown to him, of which seven be-
long to our fauna. With the view of endeavoring to supply the
deficiency, as far as our species are concerned, as well as of making
known to American students the results of Harold's studies, the fol-
lowing brief memoir has been prepared.

Our species may be separated into two groups, characterized as
follows :
Scutellum hastate, that is, narrowed strongly near the base, the sides

at middle angulate; sides of thorax never setose Group I.

Scutellum oval, never hastate ; sides of thorax in many species setose...GRoup II.

Group T.

The first group contains all the larger forms and may be divided
into whyjed and apterous species. The latter have the elytra of oval
form, the humeri broadly rounded and no humeral umboue; the meta-
sternum is always very short and the rhomboidal space at its middle
much broader than long. The winged species have oblong elytra, the
humeri more abrupt aud the umbone always distinct; the meso-
sternum is normal in form and the rhomboidal space at middle at
least as long as wide.

The following table gives the other characters : '

Elytra oval, body apterous, no humeral umbone scntellaris.

Elytra oblong, body winged, humeral umbone distinct 1.

1. Elytra with rows of tubercles very distinct and tomentose 3.

Elytra with rows of tubercles much less distinct, never tomentose 3*

2. First joint of an ton nte with dark brown hairs; club dark srsibroxu**.

First joint with rufous hairs; club rufous or cinereous 4.

4. Elytral tubercles round, their entire surface tomentose iiiOiiacliiiM.

Elvfral tubercles oblnng, the anterior portion of each glabrous aNpci*.

3. Sides of thorax near the hind angles rather deeply incised ; elytra not dis-

tinctly tuberculatp..^ subcrosuJ*.

Siilos of thorax not or very feebly incised; elytra with well nniikod rows of
glabrous tubercles pHH<-«ntus.

These species liave a facies totally different from thosi; of I lie next
group arisinj; principally from tlu^ torni of the thorax as well as its
sculpture. The hase of the thorax here is always subpediineulate and
consr((U(Mitly near the sides is always distant from the base of the
elytra, the hind aniiles are always obtuse and the margin in front of
them either with a well marked incisure or a feeble sinuation. These
characters are entirely absent in the next group and even in those
species in which the base of the thorax is deeply sinuous on each side
{ Soitor;i\, (ithrrni/nt us, etc.). there is no space between the base of
thorax and elytra, when in the normal position.

Lee. loc. cit., p. 21-) ; Harold, Col. Hefte, ix., ^. p. 56.

By the characters already mentioned this species may be readily
known. The three synonyms above cited all indicate well marked
varieties which appear to lead insensibly from one to the other.

A'ar. frxtntiis, Lee. — The largest form. Elytra broadly oval and
with rows of tubercles closely placed longitudinally, but with moder-
ately well marked intervals between the rows. Sides of thorax near
the base with a slight sinuation.

Var. scutrl/an'n, Say. — Elytra rather less broadly oval. Tubercles
more distinct, flatter, not confluent longitudinally but with well
marked intervals between them and without any intervals between the
rows. Sides of thorax entire.

Var. siitiirali.s. Lee. --Tubercles more convex and exhibiting a tenden-
cy in the rows to alternate with larger and smaller tubercles, which are,
however, clo-sely placed longitudinally and laterally. Sides of thorax
entire.

Var. iimljonatiis, Lee. — Elytra distinctly more oblong. Rows of
tubercles decidedly alternating, the tubercles rather closely placed but
of irregular polygonal form. Sides of thorax entire. The thoracic
sculpture CMiisist.s of four oval tubercles usually smooth and shining,
placed along the basal margin, the central pair somewhat larger; in
front of the outer basal tuljcrcie is another of smaller size and less

AMERICAN rOLEOPTERA. 3

rogulaily oval ; in front of the median pair of tubercles an irregular
fiirure resembling the letter "k," the vertical line being toward the
middle and the bottom of the letter toward the front. This latter figure
varies somewhat, but the sculpture as above described is that which is
characteristic of the entire group. The space between these elevated
portions is opaque and clothed with a cinereous or luteous indument,
as is also the space between the elytral tubercles.

With the known variation of jiunctatus and suherosus, as shown by
the large series before me, I cannot see that any of the above men-
tioned forms are entitled to rank as species.

Varies greatly in size. Length .60 — .80 inch; 15 — 20 mm.

Occurs in Texas, New Mexico, Kansas and also in Mexico.

T. scabrosus, Beauv. Ins. p. 175, ])1. 4b, fig. 4; Lee. Proe. Acad., 1854, p.
215; Harold, loc. cit. p. 100.

The surface of this species is almost always concealed by a brown-
ish opaque coating. The thoracic sculpture is a modification of that
described in sciifel/aris, having the basal tubercles more elongate and
coated as the remainder of the surface; the " k "-shaped figure is also
less distinctly marked. The sides of thorax are rather irregular and
near the base deeply notched, the hind angle being in the form of a
rounded lobe. The base of thorax is rather acutely lobed at middle.
The elytra are oblong in form and with moderately elevated oblong tu-
bercles having a tomentose summit. Between the rows of larger tuber-
cles is a secondary series of smaller size and less elevation, also tomen-
tose at top and on each side of these secondary tubercles a row of round-
ed granular elevations, while the surface between all these elevations is
nearly smooth. The basal joint of the antenuge, the labrum and
mandibles are clothed with stiflF brown hair and the club of the an-
tennae is of sooty color.

The presence of the triple series of tubercles in this species affords
an easier method of distinguishing it from the two following than the
color of the hairs of the basal joint of the antenna3. The median
tooth of the anterior tibite is also more distinct. Length .60 — .70
inch ; 15 — 18 mm.

This species occurs in nearly the entire region east of the Missis-
sippi river and south of the lakes, but is much more abundant in the
Gulf States.

More oblong and of less robust facies than the preceding species
The thoracic sculpture is similar and the entire surface of body simi-
larly invested. The notch near the hind angles is nearly as deep as irf
acahronua, but the angular lobe less prominent, wliiU- the sinuation of
the base immediately within the angle is much more pronounced. The
elytral sculpture consists primarily of five series of tubercles (of which
the sutural is smaller) of more or less oval form rather distantly placed
and in each row alternating with the next, and at their summits
tomentose. The spaces between the tubercles are finely l)ut sp ir.sely
granulate. At the apical fourth of the elytra one of the tubercles of
the third series is much larger, and on the fourth and fifth series a
similarly enlarged tubercle but of less size than that of the third. This
character is scarcely evident in scabrosus and much less distinct in
axpcr than in the present species.

The hairs of the basal joint are very pale brown, and the antennal
club rufous. Length .50 — .64 inch.; 13 — 16 mm.

In very well preserved specimens it will be noticed that certain
individuals have the spur of the anterior tibiae straight, and others very
distinctly arcuate near the tip. This appears to me to afford the
means of distinguishing the sexes, the former being females and the
latter males ; as the spurs are almost always more or less worn the
character becomes as useless for the determination of the sexes as is
the knowledge acquired by its presence.

Occurs in the Southern States and also west of the Mississippi from
Kansas to Teias.

T. a««por, Lee. Proc. Acad. 1854, p. 215 ; Harold, loc. clt. p. 118.

The notch at the side of the thorax is less deep than in the preced-
ing two, the angular lobe less prominent and the sinuation within it
less markeil than in monarhiiii. The elytral tubercles are here elong-
ate and closer together, and their summits tomentose except a glabrous
space at the anterior portion of each. In the interval between the rows
of large tubercles may be seen a row of small tubercles, on each side of
which is a row of moderately deeply impressed punctures. The an-
tennje are similar to those of monnchus, but the club is somewhat
darker.

This species is somewhat smaller than the preceding, being rarely
longer than .50 inch ; 13 — 14 mm.

Occurs with the preceding.

The following species have the tubercles much less elevated, of oval

or rounded form and never tomentose at tip, but smooth and shining.
The sculpture of both species is extremely variable, and has caused
them to be unnecessarily divided.

Journ. Acad. 1S54, p. 215.

This is the species so long known in our cabinets under the latter
name.

The thoracic sculpture is similar to that of nionachtis, but the tuber-
cles are much less elevated and less distinctly marked. The sides of
thorax are rounded and the emargination in front of the hind angles
broad and not nearly as deep as in monachus, etc. The elytral tuber-
cles, even in the best marked specimens, are of but slight elevation,
and between them are slight tomentose patches. The intervals are
biseriately punctured. There is scarcely any trace of subapical urn-
bone. Length .40 — .66 inch ; 10 — 17 mm.

Varieties occur with scarcely any elytral tubercles, the only sculp-
ture remaining being the punctures, and in which the surface coating
is entirely absent so that the specimens are black and shining.

I have specimens before me from every section of our country ex-
cepting California and the region to the north. It occurs in the Pen-
insula of Lower California and thence southward to Patagonia.

sus, Lee. Proc. Acad. 1854, p. 216; var. integer, Lee, var. tesselntus, Lee. loc. cit.

The thoracic sculpture is much more distinctly marked than in any
of the forms of the pi'eceding species, and in fact approaches more
nearly that of scutellaris, not only in form but also in the glabrous
summits of the tubercles. The elytral tubercles are oval, moderately
elevated, with tomentose space between them, and placed at a distance
from each other greater than the size of the tubercles. The sculpture
is of course somewhat variable and several varieties may be noted.

Var. integer^ Lee. — Sides of thorax with scarcely any evidence of
the notch near the hind angles. Elytral tubercles forming five princi-
pal series, between which are smaller tubercles not very evident, and
the intervals slightly wrinkled.

Var. morsus, Lee. — Sides of thorax posteriorly feebly notched.
Elytral sculpture similar to that of iatfger.

Var. tesselatus, Lee. — This is the larger form, and its general aspect
resembles scutellaris. The sides of the thorax have a mere trace of

notch. Tlic tiilierclos of the elytra are moderately elevated, smooth
and shii)iii<.' and those of the secondary series are iie;irly as couspicu-
ous as those of the primary.

As in aiihrrnsKn the sub-apical umbone is reduce<l to a minimum.

Occurs in the southern Atlantic and Gulf States, Kansas, New
Mexico, Arizona, Peninsula California, California and Mexico.

Group II.
The species of this uroup are all smaller than tho, c of the preced-
ini:-, and some of them are even below the medium size. The varia-
tions of the thoracic sculpture will be noted in the remarks on the
several species.

The tip of the prosternnm behind the coxre varies in form, and has
been made use of by Ilandd with success in his synoptic table. The
tip may be spiniform. sub-cariniforra or entirely flat. The hind
femora may have their upper posterior margin either spinulose or sim-
ple, and in accordance with the presence or absence of these char-
acters the main subdivisions of the table are forn)ed.

The above table is considerably changed from that of Harold, al-
though based on it. The first change that will be noticed is in the
position of erinaceus, I have associated it with copilhiris from the
entirely dark, nearly black, scale-like hairs which tip the tubercles.
All the following species have the hairs so much lighter in color that
contrast in the table is better preserved by tlie change.

In order to avoid the use of characteis drawn fr, m t le length of the
hind tarsus as compared with the middle tibia, 1 have u.^ed the
thoracic sculpture as a basis, and from it arrange the species in such
sequence ;is appears the most natural from their general aspect. Tlie
gradual obliteration of thoracic, and change of elytral sculpture are
thus shown. Of the last five species four were unknown to Harold.

moderately arcuate, base on each side moderately sinuate; median
sulcus limited by an entire ridge on each side, rarely interrupted at
middle by a transverse elevation. Elytra with rows of moderately dis-
tinct, feebly elevated, tubercles with brownish suberect scale-like
hairs; intervals with much smaller tubercles. Prosternal procei-s
elevated in an obtuse ridge. Anterior tibicXi with one small marginal
tooth and above it subserrate. Posterior femora spinulose along the
hind margin. Length .36 — .40 inch; 9 — 10 mm.

Occurs from Pennsylvania to Arizona and Kansas.

T. K<'ni"inIa(iiH, n. sp.

Oblong, moderately robust. Clypeus obtusely rounded, bead
coarsely punctured. Antennae dark brown, club fuliginots. Tborax
more than twice as wide as long, sides moderately arcuate, disc longi-
tudinally sulcata, sulcus interrupted at middle. Sutural row of tuber-
cles small, the others strongly elevated, each tubercle elongate, those
of the second and third rows forming a continuous ridge at basal third,
at summits with short, pale rufous scales. Elytral margin serrate in
in its entire extent. Prosternal process in form of an elongate tuber-
cle. Hind femora spinulose posteriorly. Anterior tibiae serrate at
base, unidentate below the middle of the outer margin. Length .40
— .44 inch; 10 — 11 mm.

The facies of this species is such that it never would be confounded
either with tKhercnkitus or Sonorse, being more robust, with broader
thorax and and with its tubercles strongly elevated, much more so, in
fact, than in any species in our fauna.

Specimens have been sent me by Mr. H. Edwards, of San Fran-
cisco, collected at San Diego. This species has been long known to
us under the above name in the cabinet of Dr. Leconte.

I cannot find that it has been described, and I retain the name
under which we have known it to avoid confusion.

T. i«ionor9C, Lee. Proc. Acad. 1854, p. 211 ; alternans \\ Lee. loc. cit. p. 212;
Lerontei, Harold, loc. eit. p. 156.

This species closely resembles tithrrculafits^ and differs in having the
elytral tubercles less elevated and covered with short, pale rufous scales.
The intervals have smaller tubercles, less evident at middle and also a
double row of punctures, and near each puncture two small granules.
Elytral margin finely serrate. Presternum, anterior tibiae and pos-
terior femora as in tvberculatus. Ijength .32 — .40 inch; 8 — 10 mm.

I cannot find that T. Sonorse difiers at all from that which we have
known as a/lernans, and therefore drop the latter name (being preoc-
cupied) and also that which Harold has given in its stead.

Occurs in Kansas, Texas and Arizona and the adjoining regions of
Mexico.

T. crinacen^i, Lee. Proc. Acad. 1854, p. 212; Harold, loc. cit. p. 180.

This species resembles tubp.rcufatus very closely but is rather more
robust in form. The clypeus is more distinctly angulate at middle
and the front with two setigerous spots. The median sulcus is feebly
interrupted. The elytral tubercles are feebly elevated but clothed at
summits with erect black setae, the intervals have smaller tubercles

scarcely evident at the disc and small granules irregularly disposed.
The prosternal process is slightly impressed at middle. The hind
femora are mutic. Anterior tibiae finely crenulate at base and
with a small tooth slightly below the middle. Length .25 — .28 inch ;
6 — 7 mm.

Occurs in New Jersey, Illinois, Georgia, Indian Territory.

Elytral tubercles feebly elevated, at summits tomentose with black,
tubercles distant and small, intervals with smaller tubercles, scarcely
evident at the sides, suture slightly elevated. Prosternum at tip
slightly elevated. Anterior tibiae unidentate externally \nd very fee-
bly serrate. Length .36 — .44 inch; 9 — 10 mm.

Occurs from Canada to Texas and Kansas.

Elongate ovate. Clypeus rounded. Thorax transversely quadrate,
sides feebly arcuate, hind angles rectangular, median sulcus feeble,
entire. Lateral margin of elytra entire, tubercles very feebly elevated,
elongate and bisjriately squammulato-pilose, intervals with very small
pilose spots, and biseriately punctured, punctures large but shallow.
Antennee rufous. Anterior tibiae with obtuse marginal tooth and at
base feebly serrate. Hind femora not spinulose. Length .40 — .48

The form of this species is very nearly that of the preceding.

Occurs from Canada to Georgia.

T. sordidus, Lee. Proc. Acad. 1854, p. 211; Harold, loc. cit. p. 177.

This species recalls the form and aspect of tuberculat us. The me-
dian sulcus of the thorax is feebly interrupted and the costae are sinu-
ous, the hind angles are subacute. The elytral sculpture is nearly
that of tuherculatus, but the scales at the summits of the tubercles are
much paler. The elytral margin, especially at base, is serrulate. The
tip of prosternum is an acute tubercle. The hind femora mutic. The
anterior tibiae above the marginal tooth finely serrulate. Hind tarsi
shorter than the middle tibiae, joints 2, 3, 4 longer than wide. Length
.24 — .32 inch; — 8 mm.

Occurs from Canada to Georgia and Kansas.

The middle and hind tibiae have a slight tooth on the outer margin
near the middle tipped with several short spinous hairs,

1 have before me a specimen that purports to be typical, bearing
the label in the writing of Harold, which does not, to my mind, agree
with that author's description and in fact is merely a specimen of
frrrcsfris and which Dr. Leconte informs me was the subject of dis
cussion at the time it was received by him from that author.

In their superficial as^pect /vveicoUis and terrestris diifer nearly as
much as erinaccuH and nordidus, for while the former in each case has
erect scale-like setae, the latter has short scales scarcely at all erect.

Occurs in Illinois, Missouri and Kansas.

212; Harold, loc. cit. p. 179.

This species and the preceding, as may be inferred from the above
remarks, are very closely allied, and the only points of difference are
that the tubercles in the present species have short scales, the sides of
thorax less rounded, more decidedly convergent in front and scarcely
at all narrowed at base. The large majority of the specimens are also
smaller than those of the preceding species varying in length from

dorsal sulcus very feebly impressed. Elytra punctato-striate, intervals
leebly convex and with very feeble tubercles tipped with rufous scales
in a double series. Prosternal process rarely in the form of an acute
tubercle, usually luii^itudiually cariniform. Hind tarsi moderately
long, the joints 2, '6, 4 longer than wide. Lateral tooth of anterior
tibiae very small, above which the tibiae are simple. Length .24 — .26
inch ; 6 — 6.5 mm.

This species occurs from Canada to Louisiana.

T. fascifer, Lee. Proc. Acad. 1854, p. 213.

This species closely resembles the preceding. The thoracic sculp-
ture is still more obliterated. The elytral tubercles are obliterated
and their places supplied by small, round, very regularly placed
patches of rufous scales. The hind tarsi are short. The anterior
tibiae bidenticulate externally and serrulate at base. Length .26 inch ;
6.5 mm.

The patches of scales are of equal size on all the intervals.

Occurs in California.

Closely allied to aequalis. The thorax is similar in form and sculp-
ture. The elytra have the intervals slightly alternating, the tubercles
very feeble and tipped with rufous scales biseriately arranged, the
tubercles on the more convex intervals being more elongate and con-
spicuous than those of the alternate intervals. The hind tarsi are
elongate. The anterior tibiae bidenticulate near the tip on the outer
margin and serrulate near the base. Length .20 — .28 inch ; 5 — 7
mm.

This species occurs in every quarter of the globe. In our own
fauna it occurs from Canada to Texas. The European synonymy has
been omitted for obvious reasons.

T. atrox, Lee, Proc. Acad. 1854, p. 214.

This species recalls in its outline capillaris, but is much less convex.
Clypeus rounded. Thorax similar in form to um'striatus, sides moder-
ately arcuate in front, slightly sinuate at base, hind angles acute, sur-
face sparsely punctured, discal channel entirely obliterated excepting
a slight impression in front of the scutellum. The elytra have broad
shallow striae, the edges of which are slightly raised and with trans-
verse punctures not closely placed; the intervals are feebly convex
and with a row of small punctures moderately closely placed, each
bearing a short erect brownish hair. Hind tarsi elongate. Anterior

tibia3 bidcntate externally the larger tooth median, one more basal
smaller and with the margin near the base crenulate. Prosternal tip
spiniforui. Hind femora spinous along the posterior margin. Length
.32 inch ; 8 mm.

The prosternum of this species is distinctly spiniform in well pre-
served specimens, but in the type is scarcely less prominent than in
terrestn's, etc. Its aspect is that of the species with which it is placed,
although the surface is entirely without coating as in the two follow-
ing. It may at all times be known irom any of our species by the
uniseriate arrangement of the short spinulose hairs of th(! elytral in-
tervals.

Specimens are known to me from Kansas and Illinois.

This species is evidently closely allied to Eversmanni of Europe.

T. laf icollis, Lee. Proc. Acad. 1854, p. 213.

Form nearly that of sefjualis, but very slightly broader. Surface
black, shining. Clypeus rounded, head sparsely but moderately
coarsely punctured. Thorax more than twice as wide as long, sides
moderately arcuate and very feebly sinuate near the hind angles which
are rectangular, surface shining, coar.sely punctured, dorsal sulcus ob-
literated except a feeble ante-scutellar impression. Elytra black,
shining, punctato-striate, intervals equal, nearly flat, with slight ine-
qualities not amounting to tubercles, each bearing two or three short,
erect brownish spiculae placed in a transverse row. Prosternal tip
feebly convex. Hind tarsi moderately long. Anterior tibiae feebly
tridenticulate on the outer edge. Length .2(i inch; 6.5 mm.

The slight inequalities which, in this species, replace the elytral
tubercles of others appear to be rather transverse folds and are moder-
ately distantly placed. The appearance of this species is totally unlike
anything in our fauna.

One specimen, New York.

sinuate, hind angles rectangular; disc moderately densely punctured,
median sulcus obsolete. Elytra black, shining, deeply striate, striae
coarsely and moderately closely punctured, intervals convex and with
fine punctures placed in pairs, which bear very short pale setae. Hind
tarsi rather short. Anterior tibia) finely bidenticulate externally and
serrulate at base, apical angular to(jth deeply emarginate. Tip of
prosternuni in form of a short carina. Length .24 inch; mm.

-Argynnis Rhodope, n. sp.

Primaries of median width, moderately arched, straight on hind
margin.

Male. — Expands 2.2 inches. Upper side deep red fulvous, the basal
portion of both wings up tn the mesial band dark brown ; hind margins
bordered by two heavy parallel black lines, which enclose fulvous spaces
between the nervules ; on primaries these lines are frequently conflu-
ent, then forming a broad band ; the submarginal black spots lunular
confluent, resting on the marginal lines throughout and enclosing sub-
ovate fulvous spots; the other markings on primaries as in allied
species, but heavy, very much as in A. Mont kola ; secondaries have
submarginal black spots equal in size to those on primaries ; the mesial
band narrow, confluent; the black discal spot oval, with a narrow, deep,
fulvous sinus; beyond to base the ground is black in the cell and for
some distance on either side of cell, covered by partially brown scales,
and on this, next anterior to the mesial band, in the upper discoidal
interspace, is a long fulvous spot, and on the sub-costal interspace a
second, smallerj; fringes alternately luteous and black, the black pre-
vailing on primaries.

Under side of primaries deep red along the whole hind margin
quite up to the line of rounded spots; sometimes the basal portion
up to the mesial band is of same hue, but in other cases it is paler;
the sub-costal and discoidal interspaces as far as the red marginal
space being yellow, as is also the posterior part of cell ; the sub-mar-
ginal black spots diffuse, the lower ones produced nearly to the rounded
spots ; the enclosed spots small, triangular, rather lunular next inner
angle, and the upper five or six either yellow with a few silver scales,
or well silvered ; on costal margin three sub-apical spots, either yellow
or silvered.

Secondaries uniform deep red from base to margin, except that
sometimes there is a narrow pale space between the two outer rows of
spots, as of a yellow sub-color, washed with red; in some cases the
middle of the wing, next anterior to the second row of spots, is much
covered with black ; the marginal spots well silvered, narrow, elongate,
lunular posteriorly, the others sub-ovate ; the spots of the second row
are nearly equal in size, excepting the fourth, which is minute; the
first three, the fifth and sixth, sub-quadrate, the seventh a paral-

lelograra, the eightli, on the margin, nearly or quite olisolote ; all hoaviTy
edged above with black ; these spots either well silvered nr yellow-
white sprinkled with scales of silver; in the third row are five similar
spots, the first, fourth and fifth nearly ecjual, lunate, the second a
point, sometimes wanting, the third sub-triangular edged posteriorly
by black; all heavily edged above with same color; in the cell a
small rounded spot, and at the base of median nervure au oval, both
ringed with black; patches of silver at base of cell, at origin of sub-
costal, and on shoulder; abdominal H)argin very lightly silvered; body
above black covered with brown-fulvous hairs; beneath light fulvous,
abdomen buff; legs i'ulvous; palpi fulvous, buff at base, at the sides
black hairs; anteuna3 fuscous above, ferruginous below; club black,
ferruginous at tip.

Crotch, Escj.

Kaf yrii!i» I'hocus, n. sp.

Mall-. — Expands 1.6 to 1.8 inch. Upper side uniform brown, of
medium color ; primaries have one small black ocellus in upper dis-
coidal interspace, sometimes in a narrow yellowish ring, and with a
white central dot, but in most cases this last is wanting, and the ring
represented by a pale shade of brown, and sometimes is altogether
wanting; occasionally there is a second ocellus, smaller than the other
in lower median interspace, black without pupil.

Under side of primaries much the same shade as above, sometimes
tinted with yellow ; of secondaries rather darker brown than above, es-
pecially over the bas;il half of the wing; hind margin preceded by a
dark common line often obsolete; both wings reticulated with fine,
abbreviated, darker brown lines and streaks ; the ocelli on primaries re-
peated, enlarged, with small white pupils and well defined yellow
irides; secondaries have two minute black spots, scarcely more than
points, one in upper discoidal, the other in lower median interspace,
each with white dot; traces of such a spot are sometimes seen in sub-
median interspace.

Body con-colored ; legs yellowish; palpi fuscous; antennae fuscous
above, cretaceous below ; club fuscous, ferruginous at tip.

Female — Unknown.

AMERICAN LEPIDOPTERA. 15

From several males taken at Lake Labaclie, British Columbia, by
O. R. Crotch, Esq., in 1873.

This species is of the size of small JVrpheJp, and is plainer colored
and with fewer spots. In same vicinity were taken specimens of
•S*. Boopis^ Behr. Also of Colias Phihdice. and Art/ynnis^ Aphrodite,
neither of which have been known by me hitherto from the Northwest
coast. Also one specimen of Vanmsa J (t/l/um, and three females of a
Collar, probably Scudderii, Reakirt ; specimens of Arg. CharUlea, or
Boisdavallt, considered by some to be a dark var. of Charidea. On
Bald Mountain near Lake Labache were taken diminutive specimens
of Argi/nnis Bischoffit, Edw., hitherto reported only from KodiaL
Near Lake Labache also were taken Arg. Brem»en\ Edw., as well as
at Victoria, Vancouver's Island. On this Island a fine specimen of
Chionohas Gigast, Butler, was taken, and specimens of Cf)lias Interior^
Scudder. Among the Pleridx, taken by Mr. Crotch, were Pallida.,
Scudder (Syn. Castoria., Reakirt), and Venom., Scudder, probably
syn. with Yreka., Reakirt. Also Okracea; all these from Lake La-
bache.

ries a narrower space, divided by the black nervules; anterior to
these lines on primaries a series of black lanceolate spots, the three or
four next apex connected and resting upon the inner line, the others
separated and not touching the line; on secondaries a series of lunu-
lar separated spots; the rounded extra-discal spots as in Nokomis;
small on secondaries, rather large on primaries; the markings on disk
and to base as in Nokomis, heavy on primaries, light on secondaries,
the discal band on the latter broken into small, separate lunules; the
spot on the arc like the letter S; fringe of secondaries light fulvous,
of primaries deep fulvous, black at tips of nervules.

Under sider of primaries cinnamon-red from base to hind margin
and over entire wing except a small sub-apical space across the sub-
costal nervules, which is bright ochraceous-yellow, and a brown patch
just anterior to this on costal margin; the black markings repeated;
the five lanceolate spots next apex enclosing silver lunules; three
silver spots on the brown costal patch, one of them minute.

being but partially fuscous ; the anterior portion of these spots, on both
margins, cut off by an irregular black line ; the 4tb row is basal and
is separated from the 3d by a broad space, and consists of four irregu-
lar, confluent spots; the outer edges of the band thus formed edged
with black ; the 4th spot confluent with the con-colored abdominal
margin; in cell an orange bar on either side the triangular spot; a
similar bar in the interspace above cell, and an orange lunule in sub-

the third, or discal row, are paler than the rest of the wing; and the
three outer rows on primaries likewise paler; under side similar in
color and markings to male.

From Montana, Nevada and Southern Utah. Specimens have been
received from Dr. Hayden's Expeditions and Lieut. Wheeler's of 1872.
Also from Henry Edwards, Esq. This species is at once distin-
guished from its allies by the yellow-white under surface, especially of
secondaries, this color nearly occupying the whole wing.

Synchloe Crocale, n. sp.

Male. — Expands 1.7 to 1.9 inch. Upper side brownish-black,
spotted with white ; primai-ies have a sub-marginal row of points,
sometimes complete from apex to lower branch of median, but usually
in part obsolete, the two spots on first and second median interspaces
only appearing; a sinuous extra-discal row of points or small spots
across the entire wing, seven in all. but sometimes the one next inner
margin accompanied by an eighth ; a discal row of conspicuous spots,
also sinuous, usually incomplete by the absence of one spot from
upper median interspace, — this spot when present, minute; and a
narrow spot in cell, often wanting ; secondaries have a transverse row
of spots on middle of wing, which are regular, narrow, elongated, and
equal; at anal angle a fulvous patch, which extends a little distance
up the abdominal margin ; fringes white, black at tips of nervules.

absent; below cell of primaries two white points.

From several males and one female, taken at White Mountains.
Arizona, in 1873. by Mr. Henshaw, of Lieut. Wheeler's Expedition.

I submitted one of these specimens to Mr. A. G. Butler for deter-
mination, and he informed me that two examples from Mexico were in
the British Museum collection, and that they were regarded by him as
a di.stinct species, allied to Lacinia and Hippodrome.

Geirocheilas Tritonia, n. sp.

Male. — Expands 2.3 inches. Upper side velvety, blackish-brown,
changing to brown on hind margin of primaries with an olivaceous
tint at apex ; co-stal edge of primaries near apex yellow-white ; be-
yond disk a transverse row of four white points, set in middle of the
upper discoidal and three next lower interspaces ; the last point some-
times wanting on upper side ; secondaries have a broad marginal band
of dull ferruginous, even edged within, reaching the margin on that
part of wing between sub-median nervure and the upper branch of
median ; beyond this last receding from the margin, but usually con-
tinued past the upper branch of sub-costal and gradually diminishing
to a point, sometimes, however, terminating squarely at the lower

AMERICAN LEPIDOPTERA. 19?

branch of same nervure; through this band runs an indistinct undu-
lating brown line, parallel to and near the margin ; beyond upper
branch of median the space between this line and margin is brown,
color of apex of primaries; fringes of primaries black at tips of
nervules, yellow-white in the interspaces, of secondaries nearly all
fuscous, there being but a few gray hairs in each interspace.

Under side smoky-brown; the white spots repeated, enlarged three-
fold, each forming the pupil of a rounded black ocellus ; secondaries
have a broad extra-discal band, ferruginous and lilac, with scattered
yellow scales, on the posterior half of wing, lilac on brown ground
apically ; on the anterior edge of the band, upon small ferruginous
spaces free from lilac, is a row of straw-colored points and spots, com-
mencing in a point on the lower sub-costal interspace and continuing to
sub-median nervure, just before which are two points ; the three spots
on the three median interspaces crescent or V-shaped ; in some cases
these larger spots re-appear on upper side ; posterior to the band, the
sub-marginal area is brown, sharply lunated, each lunation formino-
internally a semi-circle, and through all runs a streak of ferruginous,
more or less irrorated with yellow; sometimes the streak is limited to
the three interspaces next abdominal margin.

I>eNerlptionN of New Nperics of (Jnited NIates
COL.EOPTEKA.

BY GEO. H. HORN, M. D.

'I'his short contribution to Coleopterology was begun with the in-
tention of making known the new species brought by Mr. (x. K.
Crotch, belonging to the families to which the author had more
especially given attention. There being many new species in these
families from other parts of the country, this opportunity has been
made use of to add descriptions of these, as well as to make known some
.synonyms, and to present synoptic tables of several genera, in order
that the species may be more readily recognized.

The attention of collectors in various parts of the country is called
to the species of Corphyra. The number occurring in California
alone is nearly equal to that of the entire region east of the Rocky
Mountains, and this fact gives rise to the suspicion that the species of
the latter region have not been properly collected and examined,
owing to their great superficial resemblance.

The collections of Mr. Crotch show that, although very much has
been done in the development of the Coleopterous fauna of the Pacific
region, much remains to be done, especially in the smaller species,
uud to these the attention of collectors is particularly requested.

CYCHRUS, Fab.

C mimus, n. sp. — Black. Head smooth, transversely moderately convex,
clypeus with slight triangular impression at middle. Thorax cordate, not
longer than wide, sides arcuate in front, sinuate posteriorly, hind angles rect-
angular, surface sub-opaque, median line finely impressed, basal transverse
impression deeper, margin finely reflexed. Elytra oval, slightly more nar-
rowed posteriorly, convex, finely striate, striae with coarse, moderately deep
but not close punctures. Body beneath smooth, shining, reflexed portion of
elytra sparsely punctate. Length .56 — .68 inch; 14 — 17 mm.

The males of this species have the anterior tarsi with three joints
dilated and pubescent beneath, and in the group thus characterized it
ii> allied to xtriafus and ubliquus especially, differing from the former
by its broader thorax and more deeply punctured elytral striae: from
tlie latter by the sides of thorax not being oblique. The latter species
(oh/iquux) has not the triangular impression at middle of clypeal mar-
gin and has the middle portion of the head more convex. With the
exception of the tarsal character of the male, this species cannot in
description be distinguished from pitnctatus, the only noticeable super-
livial difference being that punctatm has the striae much less and the

AMERICAN COLEOPTERA. 21

punctures rather more distinct. The resemblance between these two
species has a parallel in another portion of the series, ventricosus and
alternatus of which the females are at times very troublesome to
separate.

Numerous specimens were collected by Mr. Crotch along the Santa
Ana River, at Sau Bernardino, California.

HET.SRIUS, Erichs.

H. tristriatus, n. sp. — Form broadly oval, robust; color castaueous,
shining; surface sparsely clothed with recumbent pubescuce intermixed
with moderately long yellowish hairs. Head sparsely punctured, front con-
cave. Thorax wider thaa long, slightly wider at base than apex ; on each side
a deep oblique groove, deeper posteriorly, dividing the surface into a discal
and lateral portions; discal division shining, very sparsely punctured; lateral
portion divided again in two by a deep transverse groove, the posterior
being elongate oval, smooth, shining, the anterior flattened but irregular,
dilated in front, and with sparsely punctured surface. Elytra with the sub-
humeral (or marginal) stria extending two-thirds the length of the elytra, first
dorsal entire arched at tip toward the third, second very slightly shorter, third
entire, striae deeply impressed at basal end, their outer margins being elevated.
Propygidium sparsely punctured, pygidium smooth with few punctures at the
sides only. Prosternum at tip deeply emarginate, stria extending entirely
around the tip, anteriorly moderately eonsticted and at extremity truncate
and perforate. Mesosternum with distinct marginal line. Metasternum and
abdomen smooth, shining. Length .10 inch ; 2.5 mm.

The appearance of this species is very much that of niorsus, but it
is smaller and relatively broader, the thoracic angles are less dilated
in front although of similar aspect. The striation of the elytra is en-
tirely different and the legs of the present species very much shorter,
resembling those of our other species.

Several specimens of this species were collected by Mr. Crotch, at
Calaveras, California.

PAROIIIAL.IJS, Erichs.
P. difiieilis, n. sp. — Oblong oval, sub-depressed, piceous, shining. Tho-
rax and elytra moderately coarsely but not densely punctured. Elytra with-
out traces of dorsal striae, sutural moderately impressed, extending two-thirds
to base. Body beneath much more finely and sparsely punctured than above,
mesosternum with entire marginal stria. Length .08 inch; 2 mm.

This species possesses characters of biatnatus and semimdum. Of
the former it has nearly the form and a similar mesosternal line, and
with the latter it agrees in the possession of the abbreviated sutural
stria.

Several specimens collected by Mr. Crotch, Mojave, California.

22 0. H. HORW, M. D.

NOSiODKNDRON, Latr.
JK, caliCbriiirum, n. sp. — Form broadly oval, moderately convex, bhick,
feebly shining. Head moderately coarsely and closely punctured. Thorax
less densely punctured than the head or elytra and more shining, sides very
feebly arcuate Elytra subopaque, coarsely, densely and rather deeply punc-
tured, punctures at sides denser but smaller, and with small, round tufts of
short, erect yellowish scale-like hairs arranged in fine series on each elytron
I those on the dorsum usually lost). Body beneath opaque. Mesosternum very
coarsely punctured, abdomen more finely and sparsely punctured. Length .18
inch ; 4.& mm.

This species is of the same form and size of our Eastern species,
fimiu which it diflFers by its more opaque and closely punctured sur-
face and the possession of the elytral tufts. In the latter character it
resembles the transatlantic species, y«scicM/ore, with which I have been
uuable to compare it.

One specimen from California, kindly given me by Mr. Ulke;
others were collected by Mr. Crotch, at Calaveras, in the same State.

EiiTHESOPrS, Escb.
E. bicolor, n. sp. — Oblong, rufo-piceous, thorax and head mfous, elytra
black, legs testaceous. Head sparsely punctured. Thorax slightly longer than
wide, in front feebly arcuate, at base slightly broader, surface shining, sparsely
punctured. Elytra deeply striate, strise coarsely and deeply punctured, inter-
vals convex, irregularly biseriately punctulate and obsoletely reticulate. Body
beneath sparsely and finely punctured. Antennse and palpi testaceous. Claws
broadly toothed at base. Length .22 inch; 5.5 mm.

The surface is very sparsely pubescent. The thoracic punctures
are those of the coarser series, the finer intermediate punctures being
scarcely visible. Differs from our other species by its color.

One specimen presented by Mr. Edw. Tatnall, Jr., by whom it was
collected in Delaware.

Oardii'phorus mimeticus, Horn, (Trans. Am. Ent. Soc, 187*ii, p.
147,) appears to be merely a male of C Edwardsii, Horn. The
former species has the humeri only red, while in the latter the exten-
sion of that color embraces the entire elytra, except an elongate, fusi-
form, sutural black stripe. The former name should be suppressed.
The determination is founded on a moderate series brought by Mr.

•obtusely carinate, surface densely and njoderately coarsely punctured and 8ub-
opaque, with short black hairs. Scutellum black. Elytra sanguineous with
apical irregularly cordiform spot involving the entire apex, surface sparsely
clothed with short, erect pubescence agreeing in color with the surface, feebly
striate, stri« moderately coarsely punctured, intervals flat, sparsely punctulate.
Body beneath black, sparsely punctured and with short, black hair. Legs
black, tarsi rufous. Length .36 inch ; 9 mm.

This species is allied to cordi/er and Behrensti, and differs from the
former in being less depressed and the thorax more densely and
coarsely punctured and opaque. la cord!/er the apical spot is exactly
cordiform in shape and does not attain either the lateral or apical
margins, and there is also an ill-defined spot on each elytron behind
the scutellum. Behrensii has the thorax shining and much more
sparsely punctured and the hind angles more strongly cariaate.

Specimens were collected by Mr. Crotch, at Tahoe, California.
The species is dedicated with pleasure to Mr. E. L. Phelps, throu^'h
whose skilled assistance Mr. Crotch was enabled to accomplish such
good results.

GL.YPHONYX, Cand.

G. miineticiis, n. sp.— Elongate, rufo-testaceous, sparsely pubescent^
Head coarsely, deeply and densely punctured. Thorax longer than wide, sides
parallel, anterior angles rounded, hind angles very feebly divergent, and with
a very long carina, extending in front of the middle, very close to the mar-
ginal line posteriorly; basal impression moderate; surface shining, sparsely
and moderately coarsely punctured. Elytra slightly wider than the thorax,
deeply striate, striae coarsely, deeply and closely punctured, intervals convex,
more elevated at apex, very sparsely puncticulate. Thorax beneath more
coarsely punctured than above, body and abdomen more finely and densely
punctured. Length .24— .26 inch; 6—6.5 mm.

In one specimen before me, smaller in size than the other, the
eighth elytral interval is very strongly elevated at tip, forming a well
marked carina. This species may be distinguished from either of
those previously known by its more elongate form, more convex ely-
tral intervals and the sexual (?) character above indicated. At first
sight the species might be taken as a Horistonotus, and its resemblance
to H. Uhlerii or Esthesopus humilis, is very great.

Two specimens from Texas were kindly presented by Mr. William
Jiilich, of New York.

Limonitis cribricollis. Horn, should be suppressed, the specimen ou
which it is founded being immature and without any doubt Melanotan

Oi^iTODKM, Lee.
O. pnncticollis, n. sp. — Form slender, surface sparsely clothed with
very short pubescence. Head very densely and coarsely punetured, black ;
antennte CJ, ) longer than the head and thorax, subserrate. Thorax blaik.
moderately shining, longer than wide, sides rery feebly arcuate, hind angh-s
slightly divergent and moderately strongly carinate and an extra-angnlitr
carina parallel with the margin, short but well defined, base of thorax bisinu-
ate and opposite the scutellum deeply eraarginate, the emargination obtusely
toothed at middle; surface strongly conrex, coarsely, deeply, moderately
densely and evenly punctured. Scutellum oblong, shining, slightly impressed
longitudinally. Elytra testaceous, suture and base piceous, surface moderately
shining, (sutural stria alone entire), vaguely and irregularly punctured and at
base with a slight humeral oblique impression. Body beneath piceous, thorax
less coarsely punctured than above, metasternum and abdomen sparsely and
finely punctured, shining. Legs testaceous. Length .24 inch; 6 mm.

This species reseoibles tenuicollis, Rand., in form and coloration,
and appears to differ only in the punctuation of the thorax, which is
.shinin<r, and nearly smooth in tenuicollis, while in the present species
it is very coarsely, deeply and rather densely punctured.

One .specimen collected by Dr. Elliot Coues, near the northern
boundary of Dacota, while naturalist of the North Western Boundary

APLASTUS, Lee.
Several new species having appeared, it seems advisable to present
some scheme, by which they may be distinguished, founded on char-
acters least subject to variation. The following will serve for those
at present known :

Third joint of antennas similar in size and shape to the fourth.
AntenniB slender, feebly serrate, three basal joints only pilose; sides of tho-
rax parallel, not margined, hind angles strongly divergent.

angusticollis.
Third joint of antennte always much smaller than the fourth, sometimes globu-
lar, never triangular; antennse with short erect hairs.
Thorax not margined.

Antennae strongly serrate, joints 2, 3 very small nearly equal, together
slightly longer than half the fourth.
Elytra scarcely striate, thorax very sparsely punctate.. ..tenuiforuiis.
Elytra moderately deeply striate, thorax coarsely and moderately

densely punctate corymbitoides.

Antennae serrate, joint 3 more than twice the length of 2, and together

nearly as long as the fourth speratus.

Thorax with ihe sides distinctly margined, at least at base.

Form slender, tarsi slender and as long or longer than their tibiw. Color

ferruginous. Pubescence coarse optfttUM.

Form shorter, less slender, thorax more convex, tarsi never as long as their
tibiw. Color piceous. Pubescence fine molcstUH.

AMERICAN COLEOPTERA. 25

A. august icollis, n. sp. — Form slender, color ferruginous, sparsely
clothed with short cinereous pubescence. Head coarsely but not densely
jiuiictured, vertex slightly impressed. Eyes more prominent than the sides of
thorax. Antennae feebly serrate, three basal joints only hairy, second joint
small, oval, third similar to and nearly as long as the fourth. Thorax quad-
rate or slightly longer than wide, sides parallel not margined, hind angles acute
strongly, sometimes very suddenly divergent, acutely carinate, surface convex,
sparsely punctured. Elytra as wide at base as thorax, elongate, feebly convex,
sides very feebly arcuate, gradually narrowing to apex, surface obsoletely
striate, intervals feebly convex, moderately densely punctured and sparsely
pubescent. Body beneath darker than above and similarly punctate and
pubescent. Tarsi slender, as long as their respective tibiae, hind tarsi some-
what longer. Length ,50 — .56 inch; 11.5 — 14 mm.

This species is the most slender of the genus and is readily known
by the characters in the table.

In the terminal ventral segment several characters are plainly visi-
ble. In those, which I take to be males, the last ventral segment
has the sides slightly oblique near the tip, while the tip is feebly
emarginate, in the other sex the segment is oval at tip and entire.

Numerous specimens were taken by Mr. Crotch, at San Die^o,
California.

A. tenuirormis. n. sp. — Form slender, color piceo-testaceous or ferrucrjn-
ous, sparsely clothed with fine cinereous pubescence. Head coarsely and
moderately densely punctured. Eyes not more prominent than the sides of
thorax. Antennae strongly serrate, sparsely clothed with short erect hairs,
second and third joints small, globular and nearly equal in size, and together
scarcely longer than half the fourth. Thorax subquadrate, slightly longer
than wide, sides very feebly arcuate and slightly divergent, not margined,
hind angles acute, moderately strongly divergent and acutely carinate, sur-
face convex, coarsely but not densely punctured, median line usually feebly
impressed. Elytra as wide at base as thorax, sides gradually narrowing to
base, surface moderately convex, obsoletely or not at all striate, interval scabro-
punctate. Body beneath more shining than above, sparsely punctulate and
pubescent. Tarsi slender as in the preceding specie?. Length .44— .50 inch;
11—12.5 mm.

The males have the sides of the last ventral segment slightly ob-
lique near the tip and the tip truncate.

The three specimens in my cabinet are from Nevada and parts of
California unknown to me.

A. corymbitoides, n. sp.— Piceous, moderately shining, sparsely clothed
with short, grayish silken pubescence. Head densely and coarsely punctured.
Antennae strongly serrate, with short erect pubescence, joints 2, 3 small, oval,
the third somewhat the larger and together not longer than half the fourth.
Thorax slightly longer than wide, convex, coarsely but not densely punctured,
median line feebly impressed, sides not margined, anteriorly feebly arcuate,
hind angles moderately divergent, carinate. Elytra as wide as thorax, sides

gradually convergent, moderately convex, surface finely but ratlier deeply
striate, striae indistinctly punctate, intervals moderately convex, moderately
densely and rather roughly punctate, prosternum in front of coxse obtusely
carinate. Body beneath sf>arsely punctate and pubescent and more shining.
Length .50 inch; 12.6 mm.

The males have the last ventral segment slightly oblique at the
sides and very feebly truncate at tip. The last ventral of the female
•is not oblique and is very slightly prolonged and oval at tip, the dif-
ference between the two .sexes in this respect is barely discernible.

iiy the form of the antennae this species is allied to mohstua. opta-
tus and teuui/ormi's; it differs from the first two by the absence of any
marginal line, and from the latter by its less slender form and rather
deeply striate elytra, and from all by the thorax more coarsely and
densely punctured. Its form is nearly that of the male of Con/mbites
ct/lhi ilriform is .

All the species of this genus have the last joint of the antein;c
rather suddenly narrowed near the tip, presenting the appearance of
the false joint so often seen in Ludius ; in mo/e.^^jts, however, this
character is barely perceptible.

Specimens were collected by Mr. Crotch, at Los Angeles, California.
A. speratUS, Lee. — In this species the thorax is distinctly louger than
wide, the sides feebly and the hind angles more strongly divergent. The
third joint of the antennse is nearly twice as long as the second, and the two
together nearly equal to the fourth. The elytra are very feebly striate, the
intervals sparsely clothed with short but coarse pubescence which conveigos
from each side of the interval to the middle and forms, apparently, lines of
pubescence. The tarsi are slender and as long as their respective tibiae.
Length .56— .fi2 inch; 14—15.5 mm.

Occurs at Tejon and Los Angeles, California.

The sexual characters are the same in this species as in angustirol-
lu. The antennae are clothed with short erect hairs.

A. optalus, Lee— Thorax as long as wide; sides distinctly margined,
gradually divergent to base, hind angles slightly more divergent, acutely cari-
nate, surface moderately convex, sparsely punctate and shin'ng. Antennae
strongly serrate, sparsely hairy, third joint elongate oval, larger than the sec-
ond, the two together equal to three-fourths the fourth joint. Elytra feebly
striate, striie punctured, intervals sparsely punctate and sparsely pubescent.
The under surface is sparsely and finely punctate. The tarsi are sleniier, the
anterior four as long, the hind tarsi longer than the tibiae. Length .60 inch.

The male of this species has the last ventral segment rather deeply
sinuate on each side and considerably prolonged at middle, the tip ob-
tusely rounded.

Occurs in the Soulheiii Coast Range and at Tejon, Califoania.

AMERICAN COLEOPTERA. 27

A. molestns, n. sp.-Piceous, feebly shining, sparsely clothed with a
very fine pubescence. Head moderately densely and rather coarsely punc-
tured. Eyes feebly prominent. Antennae serrate, sparsely hairy, second joint
very small, third larger, the two together nearly equal to the fourth. Thorax
not longer than wide, sides distinctly margined, very feebly arcuate, gradually
divergent to base, hind angles very slightly more divergent and carinate sur-
face rather strongly convex, usually moderately densely punctured. Elytra
finely striate, intervals moderately densely scabro-punctate. Body beneath
more shining than above, moderately densely punctulate. Tarsi slender but
not longer than the tibiae. Length .48 inch ; 12 mm.

The three specimens before me are probably all males. The last
ventral segment has a very feeble sinuation on each side.

Collected by Mr. William M. Gabb, near San Francisco, California.

Elytra scarcely wider than the thorax, surface scabrous, moderately shinin-
black, slightly bronzed, with broad testaceous vitta extending from the
humerus to apex. Body beneath black, shining, legs pale testaceous, upper
margin of femora and last joint of tarsi black. Lehgth .12 inch ; 3 mm

Male-Antenna black, pectinate, elytra slightly prolonged, and testaceous at
tip.

Two specimens collected by Mr. G. R. Crotch, in the region of Lake
Tahoe, California.

n. spinipennis, n. sp.— Form of auntus. Head smooth, shining black
front slightly impressed. Thorax broader than long, surface very smooth and
shining, black, lateral margins pale red. Elytra slightly broader at base than
thorax, surface feebly scabrous, bluish, moderatelv shining. Body beneath

half. Length .18 inch ; 4.5 mm.

J»/a/e.-Antennae black, joints 5—10 pectinate, joints .3, 4 triangular. Elytra
sinuate at apex, suture prolonged into a spiniform process and red, beneath
which are appendages of curious structure, one being spiniform and pro-
jecting backwards under the spiniform process of the suture and concealed bv
it from above. ^

Female. — Unknown.

Collected by Mr. G. R. Crotch, at Fort Tejon and Sauta Barbara,
California.

Two specimens, both males, are before me which differ from each
other as follows : the smaller has the antenna less decidedly pecti-
nate, the elytra more opaque and bronzed instead of blue, and the
discal black spots of thorax much smaller.

This species is closely allied to mirandus, which, however, has the
elytral appendages very prominent and has not the suture prolonged,
although there is a small juxta-sutural appendage.

^. Tlieveiietii, n. sp. — Black, with slightly bluish tinge, thorax rufmis
with (liscal black spot. Head smooth, witli slight transverse impression. An-
tennfB black, pectinate %. Thorax broader than long, sides feebly, base more
decidedly arcuate, hin<l angles broadly rounded, slightly reflexed, surface
smooth, feebly shining. Elytra bluish, opaque, finely scahn>us, at tip appen-
diculate, sutural angle prolonged in a long coriaceous process. Body beneath
and legs black with tinge of blue. Length .20 inch; 5 mm.

The elytral appendices are as usual inferior but not concealed en-
tirely from above. The sutural prolongation is limited externally by
a deep sinuation of the elytra. ,

One specimen collected by Dr. Alphonse Thevenet, Mariposa county,
(California, in the collection of Dr. Leconte.

The addition of the above species requires some modification of the
table given by me (Trans. Am. Ent. Soc, 1872, 113) for those species
in which the male has pectinate antennae.

KTIBIA, Horn.

S. ovipcnnis, n. sp. — Form moderately robust, color piceous black, shi-
ning. Head coarsely and densely punctured, punctures slightly strigose,
especially in front. Thorax nearly twice as wide at middle as long, apex
deeply emarginate, base feebly arcuate, sides regularly and rather strongly ar-
cuate, disc convex, densely and coarsely punctured, punctures slightly strigose
near the sides. Elytra regularly oval, slightly more attenuate at apex, one-
fourth broader than the thorax and nearly four times as long, convex, with
coarse punctures placed in striae at the middle of each elytron, confusetl at the
sides and near the suture and totally obliterated at apical third. Thorax be-
neath very coarsely punctured, abdomen obsoletely and very sparsely punc-
tured, inesosternum coarsely punctured, metasternum very coarsel}' cribrate.

ast ventral rather coarsely jjunctured.

AMERICAN COLEOPTERA. 29

This species may be distinguished from puncticolh's by its smaller
size, more robust form, different elytral sculpture and by the smooth
abdomen.

Two specimens were collected by Mr. Crotch, at San Diego. Cal.

S. hispidula, n. sp. — Form robust, pieeous black, moderately shining,
sparsely clothed with moderately long yellowish hairs. Head coarsely, densely
and sub-strigosely punctured, middle lobe of elypeus rounded in front. Tho-
rax twice as wide as long, anterior angles acute and very prdin inent anteriorly,
base slightly wider than apex, at middle slightly arcuate, on each si<le
feebly sinuate, hind angles rectangular; sides very feebly arcuate, disc very
convex with ante-basal transverse impression; surface coarsely, deeply and
rather densely punctured, punctures becoming slightly strigose at the sides.
Elytra broadly oval, very convex, moderately coarsely but not densely punc-
tured, punctures with faint tendency to a seriate arrangement. Thorax be-
neath very coarsely, deeply and rather densely punctured, mesosternum less
coarsely punctured, metasternum with very large, deep punctures, abdomen
moderately densely punctured. Outer margin of anterior tibiae slightly spiuu-
lose. Length .22 inch; 5.5 mm.

The appearance of this species is somewhat that of Trinrophua. It
may be at once known by its form, the very prominent anterior angles
of the thorax, and the sparsely hairy surface.

One specimen collected by Dr. Edw. Palmer, in Utah.

Besides the differences indicated in the table between this genus
and Triphalm (the longer hind tarsi), it will be observed that the
tarsi have coarser and sparser vestiture, and the elytra much narrower
epipleurae. The sexual character above indicated in S. ovipennis ap-
pears to be unique in the species of the tribe in our fauna. In form
the species more closely resemble Triorophus, but this has the vestiture
of the tarsi spinous beneath, the epistoma with much longer middle
lobe which is narrowed at base and clasped by the basal tooth of the
mandibles.

The three species forming the genus are related as follows : —

Elytra oblong, punctures larger, arranged in regular striae.

Thorax moderately emarginate in front, angles not prominent.

puncticollis.
Elytra broadly oval, punctures very irregularly-arranged.

Thorax moderately emarginate, angles not prominent ovipennis.

Thorax deeply emarginate in front, anterior angles very acute and promi-
nent, disc with ante-basal transverse impression lii!>ipi<lul£i.

The tribe Grnathosiini, as at pi-eseut constituted, appears to consist
of material entirely too heterogeneous to be associated together. 6Va-
niotus cannot form part of the tribe for the following reasons. The
metasternal episterna are broad, in fact nearly as wide as long, and

30 G. H. BORN, M. D.

rery much narrowed at the anterior extremity. The intercoxal pro-
cess is short and very broad, and the antennre are ten-jointed, the
eleventh joint being small and conical and connate with the tenth,
and finally the lateral lobes of the front are large, triangular, acute
and very prominent laterally. The genus must obviously constitute a
distinct tribe nearer the EpipJv/aini than Gnafhosiini, defined by the
characters above noted ; it caonot, as suggested by Lacordaire, be as-
sociated with Meijagenms, as this has the metastemal episterna nar-
rower.

With Craniotus removed the tribe becomes more homogeneous. It
may be observed, however, that while all the other genera have the
mandibles gi-ooved above so as to permit them, when closed, to clasp
the middle lobe of the epistoraa and thus completeli/ conceal the lab-
rum (without becoming themselves concealed when viewed from
above), Anchmoblas has the mandibles feebly grooved not clasping
the middle lobe of the epistoma, when in repose, allowing the labrum
to be partially visible, while they are completely invisible from above.
It is also the only genus without supra-orbital ridge, and has the outer
joints ot tl»e antennae compressed, broader than long and trapezoidal
in f trm. It might possibly represent another tribe, the form of the
antennae being totally unlike that of any other genus in the earlier
groups.

Tlij tribe thus becomes reduced to four genera, the relations of
which are as follows : —

Intercoxal process of abdomen broad, feebly narrowed in front, tip subtruncate
or rounded.
Tarsi spinous beneath. Hind tarsi with joint 1 equal to 3, 4.

Middle lobe of epistoma narrowed at base and clasped by a tooth-like pro-
cess from the base of the mandibles Triorophus.

Middle lobe of epistoma triangular, rapidly narrowed in front, mandibles

without basal tooth Stibia.

Tarsi with silken hairs beneath. Hind tarsi with joint I equal to joint 4
only.
Middle lobe of epistoma uarrower in front, mandibles without basal tooth,

thorax narrower in front Triphalus.

Intercoxal process of abdomen triangular, either acute or oval at tip. Tarsi
spinous beneath.
Middle lobe of epistoma narrower in front, either oval or truncate. .. Trim ytis.

The above genera all have the prothorax coarsely punctured be-
neath and the metasternum very coarsely and deeply cribrate, a cha-
racter entirely unknown elsewhere among our G nathosiini. In Trioro-
jihus it will be seen that certain specimens are stouter in form, the

AMERICAN OOLKOPTERA. 31

elytra being more broadly oval, others are more slender and always
smaller. The former I find to have a smooth head and the mandibles
very decidedly sometimes rather deeply notched. Both the above
characters are somewhat variable but hold good with the majority of
specimens, aad they appear to me to be sexual.

CHILOMETOPOM, n. gen.

Body winged, elongate oval. Front trilobed, middle lobe promi-
nent, trapezoidal, feebly clasped by the mandibles and entirely con-
cealing the labrum. Eyes with superciliary ridge, prominent and
coarsely granulated. Antennae longer than head and thorax, slender,
joints 8—10 somewhat broader, last joint equal to (heJopioides) or
longer Qibnonne) than the preceding. Mentu.n transversely hexago-
nal, large, anterior angles rounded. Maxillary palpi with last joint
elongate triangular. Prosternuin not produced behind. Legs slen-
der, anterior tibiae slender without apical prolongation, tirsi sparsely
clothed with short spines, hind tarsi moderately elongate, first joint
equal to the third and fourth together.

Two species before me agree in the possession of the above cha-
racters.

The genus is referred to Epifragini from the form of the front and
the elongate metasternum. In both species the thorax is somewhat
narrower than the elytra, although not more so than in some of our Epi-
trayus. The vestiture of the tarsi is nearly as stiff and spinose as in
Triorophua, The middle lobe of the front is very prominent, truncate
in helnpioides, and oval at tip in abnarme, the surface being flat in
the former and moderately convex in the latter. Regarding the
affinities of this genus with foreign genera I express no opinion ; from
our own genera of the tribe it is easily known, the tarsal vestiture and
superciliary ridge at once distinguish it from Schoenicus, with which
alone it could be founded. The two species are : —

broadly rounded at middle, feebly sinuate each side, hind angles subacute but
not prominent, sides moderately arcuate and slightly divergent to base. Ely-

feebly seriately arranged becoming slightly niuricate and dense at the sides
and apex. Epipleurse entire. Thorax beneath densely variolato-punotate,

at middle very sparsely punctured, sides and parapleurte very densely punc-
tured. Abdomen sparsely punctured. Femora coarsely but sparsely punc-
tured. Length .26 inch; fi.5 mm.

Th'us species superficially resembles Hdops convcxus, Lee., and does
not differ greatly in form from several species of Eurym,etopon,Q. g.
pvnctulatum and sodale.

One specimen collected by Mr. E. P. Austin, in California.

€RYPTAI>IIJS, Lee.

At the time of the preparation of the revision of the TenebrtoniJae
of the United Stiites Crj/ptadi'm was unknown to me, the type hav-
ing been lost at sea while being sent for study to Jjacordaire. lle-
cently specimens have been collected at San Diego, California, by Mr.
G. li. Crutch, and I am enabled to present the following observa-
tions : —

Head moderately deeply inserted ; epistoma subtruncate at middle
and slightly notched on each side; labrum moderately prominent;
eyes feebly transverse, coarsely granulated, .slightly notched in front
and with distinct supra-orbital ridge; mentum large hexagonal, feebly
emarginate in front; last joint of maxillary palpi elongate oval, nearly
twice the length of the preceding joint; antennae attaining the hind
margin of thorax, first joint stouter, second and fourth equal, third
longer, 8 — 11 slightly broader, the last joint oval at tip. Middle
coxae entirely enclosed without visible trochantius. Intercoxal pro-
cess narrow, rounded ut tip. Epipleurge moderate entire. Anterior
tibiic with the outer angle prolonged into a long obtuse process, sinu-
ate on its lower margin. Hind tarsi nearly as long as the tibiae, the
first joint longer than the two following combined. Scutellum very
small, between the elytra transverse.

C. inflata8, Lee. Ann. Lye. v., p. 140. — Body black, feebly shining, form
broadly oval, robust, convex, apterous. Head coarsely, densely and deeply
punclurod. Thorax more than twice broader than long, moderately emargin-
ate in front, anteriorly narrow, sides feebly arcuate, and very narrowly mar-
gined, hind angles obtusely rounded, surface densely and moderately coarsely
punctured and opaque, punctures at the sides strigose. Elytra slightly broader
than the thorax, oval, slightly attenuate at apex, surface convex, moderately
densely sub-niuricately punctured and in the intervals very minutely aluta-
ceous. Body beneath more shining than above, piceous, very sparsely punc-
tured. Legs rufo-piceous. Length .26 inch ; 6.5 mm.

From the above characters it will be seen that its place is with the

AMERICAN COLEOPTERA. 33

genera allied to Eurijmetopon and not with those in which the front is
trilobed. The notch on each side of the front is already known in
Eurymc.topon^ in fact I can see no character of importance separating
the two genera; the robust form, even, being already indicated by E.
cunvexico/le, Lee, and F. hicolor, Horn. Cryptadius should, in my
opinion, be suppressed into Eurym.rtopon.

SCHIZIL.L.1JS, n. gen.
The above generic name is proposed for a form belonging to the
tribe Cri/ptoglossini^ allied more nearly to Cenfrioptera, from which it
differs only in having the genae much broader and the eyes completely
divided, the under portion of each eye very indistinctly granulated.
The mentum is broader than long, anteriorly truncate and feebly
emarginate at middle. Front hemi-hexagonal. The antennae are 11-
jointed, the first short and stout, invisible from above, terminal joint
broadly oval, stouter than the preceding.

S. laticeps, n. sp. — Black, sub-opaque, moderately robust. Head sparsely
punctured, neck densely and finely granulate. Thorax broader than long,
apex moderately deeply emarginate, slightly broader than the base, sides
moderately arcuate, sinuate near the base, hind angles rectangular, base very
feebly emarginate, surface moderately convex, sparsely punctured and sub-
opaque and with a moderately deep, transverse, ante-basal impression. Elytra
oblong oval, not wider at base than the thorax, widest at middle, sides moder-
ately arcuate; surface moderately convex with rows of punctures on the disc
becoming irregular and sub-muricate at the sides and apexj intervals flat sub-
muricate punctate. Prothorax beneath sparsely punctate, presternum acutely
oval, slightly produced, margins slightly reflexed ; mesosternum nearly verti-
cal emarginate in front; abdomen sparsely and obsoletely punctate. Legs
black, sparsely muricately punctate. Tarsi stout. Length .75 — .90 inch; 23 mm.

The thorax of this species is similar to that of Cryptoglossa laevis,
but less convex, while the elytra resemble in sculpture Elcodes conao-
hiina. The head is much broader than in any Centrioptera in our
fauna.

The specimens, from which the above description was taken, were
captured by Mr. Crotch in the Mojave Desert, California.

EliEODEN, Esch.

E. vetorator, n. sp.— -Black, above sub-depressed, opaque,sparsely clothed
with short yellowish hairs. Form broadly ( 9 ) or more elongate ( 'J,) oval.
Head sparsely punctured and pubescent. Thorax nearly twice as wide at base
as long, apex emarginate not wider than the length of thorax, sides regularly
arcuate and gradually narrowed from base to apex, base squarely truncate,
surface feebly convex, opaque, sparsely punctured and pubescent. Elytra at
base very slightly broader than the thorax and slightly overlapped by it,

34 O. H. HORN, M. D.

Bides regularly arcuate, gradually narrowing to base and continuing regularly
the curve of the sides of the thorax, lateral margin acute at basal third; sur-
face feebly convex, opaque, sparsely pubescent and punctured, pubescence ar-
ranged so that the surface appears sub-striate. Body beneath black, shining,
sparsely punctured and with slight pubescence. Tarsi spinulose. Lenglh .38
— 42 inch ; 9..')— 10.5 mm.

The spinulose tarsi not dilated in the male, the slight dissimilarity
between the spurs of the anterior tibijc in the sexes (less marked,
however, in this species than in any other of the gwup), the anterior
spur of the female larger in every v^ay than the posterior, at once in-
dicate the affinity of this species with those of the tricostatu group
and not with opacd, with which a slight superficial resemblance would
seem to associate it. It may be at once known from every Elemles in
our fauna by its regularly oval form, equally narrowed at the two ex-
tremities, the thorax squarely truncate and its sides regularly arcuate
and gradually narrower from base to apex.

Numerous specimens of this species were kindly presented by Mr.
William Jiilichs, of New York, by whom they were procured from
Texas.

E. texaua, Lee. — From collections recently made in the northern
parts of Texas I have become convinced that this species is merely a
large variety of suturaiis, Say.

IPHTIII9IUS, Truqui.
I. zopheroides, n. sp. — Black, shining, form strongly recalling Zopherus.
Head sparsely, between the eyes coarsely and very deeply confluently jiunc-
tate. Thorax trapezoidal, wider in front, apex feebly emarginate at middle,
anterior angles very broadly rounded, sides at anterior third parallel, thence
gradually narrowed to the base which is truncate, disc convex longitudinally
and transversely, shining, sparsely punctured. Elytra oblong, slightly broader
behind the middle, convex, shining and with eight discal and a marginal row
of deep, coarse, distantly placed punctures. Body beneath black, shining,
mesosternum densely and coarsely punctured, abdomen sparsely punctured
and slightly wrinkled longitudinally. Length .80 inch; 20 mm.

The mentum of this species differs notably from that of our other
species, being trapezoidal and strongly convex at middle, the usual
form being broader with rounded angles, a median groove and on each
side slightly concave. This variation taken in conjunction with the
general form, which is remarkably Zopheroid would seem to indicate
the propriety of separating the species generically. A comparison of
the superficial characters shows nothing greatly at variance with the
other Iphthimus except the much more convex form, although the
thorax is somewhat longer and the hind angles not prominent.

AMERICAN COLEOPTERA. 35

For the unique in my cabinet I am indebted to Mr. A. S. Fuller,
who obtained it from New Mexico.

I. serratus, Mann.

This species is introduced to call attention to a curious variety,
found by Mr. Crotch, of much greater size than usual. The head and
thorax are smoother and more shining, very minutely punctulate, the
thoracic margin more broadly reflexed and very irregularly erenulate.
The elytra are subopaque and the striae with the usual punctures re-
duced to very indistinct longitudinal and transverse wrinkles, the
intervals being minutely and not densely punctulate. The specimen
is slightly more than an inch long.

NYCTOBATES, Gudrin:
N. snbnitens, n. sp.— Elongate, black, subopaque. Head very minutely
punctulate. Antennae with third joint nearly equalling the three following
together. Thorax slightly broader than long, apex truncate, base very feebly
sinuate, sides moderately arcuate in front, narrowed and slightly sinuate near
the base, hind angles acute but not prominent, surface moderately convex
sparsely and very minutely punctulate. Elytra broader than the thorax,
gradually attenuate at apical third, surface slightly more shining than the
thorax with faint rows of minute punctures, the intervals very sparsely and
more finely punctured. Body beneath shining, sparsely punctulate, abdomen
longitudinally wrinkled. Prosternum between the coxae convex, and elevated
in a slight tubercle at tip. Length .70 inch; 18 mm.

A comparison of this species with either of the others shows a
greater length of the third joint of the antennae. The sides of thorax
are more arcuate in front and more sinuate posteriorly. The entire
surface is less shining and less distinctly sculptured. The prosternum
is narrower and convex longitudinally between the coxae and elevated
in a tubercle at tip, our other species having the prosternum broader
nearly flat and not tuberculate at tip. The mentum is also more con-
vex and the anterior angles more distinct.

The unique in my cabinet was given me by Mr. H. Ulke, who ob-
tained it from Arizona.
Scotobsenus parallelns, Lee.

The males of this species have the anterior femora stouter than the
iemales, the tibiae slender at basal fourth and the inner margin covered
with small tubercles. The middle and hind femora have a silky
pubescent space along their lower edge.

PHTHORA, Muls.

P. americana, n. sp. — Oblong, ferruginous, shining. Head sparsely
punctured. Thorax broader than long, apex feebly emarginate, base feebly

36 O. H. HORN, M. D.

arcuate and slightly broader than the apex, sides very feeblv arcuate, margin
thickened and soinewliat reflexed, surface shining, sparsely and evenly punc-
tured. Elytra as wide at base as thorax, parallel, moderately deeply striate,
striaj coarsely and subseriately punctured, intervals moderately convex,
sparsely punctulate. Body beneath paler than above, very sparsely and finely
puiiclulate. Length .12 inch ; 3 mm.

The appearance of this snsect is that of a miniature but rather con-
vex Uluma It resembles also Dioedus more closely, but differs in
having the last three joints of the antennae thickened, while Dioedus
has but two.

Speciiues collected in Oregon were kindly given me by Mr. A. S,
Fuller,

5ii€APIII»E!»IA, Redt.
S. pictiiin, n. sp — Oval. Head black, surface s,eneous sparsely punctate.
Thorax nearly twice as wide as long, sides in front feebly arcuate, posteriorly
nearly straiglit and slightly divergent, hind angles rectangular, color black,
surface aeneous sparsely punctate, basal impressions extending nearly to mid-
dle. Elytra at base broader than the thorax, moderately convex, sides moder-
ately arcuate, surface striate, strisB 6nely punctured, intervals flat, biseriately
finely punctulate an<i obsoletely reticulate, color yellowish testaceous, with
basal black band broad at middle, an irregular sinuous transverse band at
middle cotnposed of lines of variable length on the intervals but shortest at
the suture, and a subapical ova! spot, apical margin piceous. Epipleurre pale.
Body beneath piceous slightly aeneous, sparsely punctulate and shining. Fo-
mora piceous, tibiae and tarsi paler. Length .14 inch; 3.5 mm.

The form of this species is broader than aeneolam and resembles
more nearly that of the European species.

Occurs in Oregon. Henry Edwards.

IIELOPJi, Fab.
II. arizoiieUNi.S, n. sp. — Form rather slender, apterous, black, opaque.
Head coarsely and rather deeply punctured. Antennae nearly half the length
of the body, outer joints slightly c unpressed, very slightly shorter. Thorax
slightly wider than long, sides feebly arcuate, margin obtuse, apex truncate,
base feebly arcuato, hind angles slightly prominent, disc moderately convex,
densely and coarsely punctured and opaque, beneath punctured as above.
Elytra oblong, humeri obtuse, surface deeply striate, strise coarsely punctured,
intervals convex and finely granulated. Body beneath black, slightly more
shining than above, raeso- and metasteriiura coarsely punctured, abdomen
finely rugulose and more sjjarsely and finely punctured. Length .34 inch;
8.6 mm,

\iy the character given in the table (Revis. Tenebrionidaa, p. .392)
this .opecies should be placed near atifcipennis, but by its opaque sur-
face and deeply sulcate elytra it differs from every other species in our
fauna.

Specimens from Arizona were kindly presented by Mr. C. V. Kiley.

AMERICAN COLEOPTERA. 37

EPICAIJTA, Redt.

E. sanguinicollis, Lee. Proc. Acad. 1853, p. 344.— Body entirely black,
head and thorax red. Head shining sparsely punctured, epistoma and mouth
black. Antennae black, filiform. Thorax not wider than the head, slightly
longer than wide, sides parallel, arcuately narrowed in front, moderately eon-
vex, median line and ante-scutellar impression feeble, surface shining, rather
sparsely but coarsely punctured. Elytra nearly twice as wide as thorax, black,
coarsely scabrous, sparsely pubescent with black, with very narrow median
stripe, sutural and lateral margins sparsely cinereo-pubescent. Body beneath
and legs black, sparsely pubescent. Length .32 inch ; 8 mm.

This species should be referred to section A of the revision of this
genus (Proc. Am. Phil. Soc. 1873, p. 95), from all the species of
which it differs by its color and the arrangement of the elytral pubes-
cence.

One female specimen, collected in Florida, was kindly given me by
Mr. Edward Tatnall, of Wilmington, Del.

E. Rileyi. n. sp. — Body black, densely clothed with recumbent ochreous
pubescence. Head densely and finely, behind the eyes coarsely punctured
•"ather densely pubescent, between the bases of the antennae a smooth polished,
triangular space and above the eyes and surrounding them on their posterior
and upper margins a sinular smooth space terminating at the inner side o(
each eye in a deep fossa. Thorax subquadrate, sides very feebly arcuate,
slightly converging anteriorly, disc feebly convex and with a vague but broad
fosrsa near each front angle, surface densely and finely punctured and densely
pubescent, the pubescence in the fossae shorter (as if shaven). Elytra one-half
broader than the thorax, parallel, suture at middle slightly elevated, surface
densely and finely punctured, very densely clothed with ochreous pubescence,
and on each side of the scutellum at base a narrow black space. Body beneath
and legs very densely clothed with a somewhat paler pubescence than above,
the abdominal segments at the sides with a small black spot and a similar spot
on the middle of segments 2, 3, 4. Length .40 inch ; 16 mm.

The eyes of this species are smooth, not at all granulated, although
the lenses are distinctly visible from their transparency; otherwise the
eyes are similar to the species of section C. The antennas are rather
setaceous as in that group. The rather deep fossae at the inner sides
of the eyes mark this species as one of the most peculiar of the genus.
Superficially the species resembles a pa]e ferrttginea, and its place in
the series is near caviceps, forming a section by itself.

The two specimens before me exhibit no marked sexual differences
and are probably both females. They were collected in Arizona and
presented by Mr. C. V. Riley, of St. Louis, to whom 1 take great
pleasure in dedicating it.

38 G. H. HORN, M. D.

E. Alphonsii, n. sp. — Black, moderately shining. Head shining, sparsely
ptinctureii, posteriorly sparsely cinereo-pubescent. Thorax slightly longer
than wide, sides in front slightly arcuate, posteriorly parallel, surface shining,
sparsely punctured. Elytra black, scabrous, very sparsely clothed with short
black hairs, suture and sides narrowly margined with long whitish hairs.
Body beneath and legs black, shining, legs sparsely cinoro-pubescent. Length
.36 inch ; 9 mm.

One specimen in the cabinet of Dr. Leconte, collected in Mariposa
County, California, by M. Alphonse Thevenet, to whom it is with
great pleasure dedicated.

The antennae of this species being filiform and the joints closely
placed, and the eyes moderately broad, coarsely granulated and
moderately convex, show the position of this species to be in the
same group with puncticnUh and ohlita. The narrow sutural and
marginal cinereous lines are found also in the group in sanyuiiiicollis.

CAXTIIARIS, Linn.

C tenebrosa, Lee.

A male of this species is in the collection of Mr. G. K. Crotch,
having the antennae very slightly thickened at middle, barely enough
to indicate its position in the group in which it was placed. The an-
tennae are, however, very short as in many of the species of group I.
being barely the length of the head and thorax. The outer spur of
the hind tibiae is stouter than the inner, very obliquely truncate and
slightly broader at tip. The following are the abdominal characters :

Mafe. — Fifth ventral segment broadly rounded, sixth subtruncate
and slightly emarginate at middle.

Female. — Fifth ventral broadly rounded, sixth oval and very feebly
emarginate at tip.

C C'rotcllii, n. sp. — Head entirely black with aeneous surface, coarsely,
deeply and moderately densely punctured, especially at the sides, sparsely
clothed with erect black hairs. Thorax broader than long, sides regularly
arcuate, basal margin slightly reflexed and feebly emarginate at middle, color
reddish-yellow, surface moderately convex and shining, very sparsely and
unevenly punctured. Elytra one-third broader than the thorax, coarsely
scabrous, black with bronzed surface, sparsely clothed with short, black, erect
hairs. Body beneath and legs black and slightly bronzed. Outer spur of hind
tibife slender, very obliquely truncate at tip. Length .30 — .40 inch; 8 — 10 ram.

Male. — Fifth ventral segment very broadly emarginate, sixth moderately
emarginate.

Female. — Fifth ventral broadly emarginate, sixth with scarcely evident
emargination.

This species is closely allied to aeneipennh, next to which it should
be placed in the table (Proc. Am. Phil. Soc. 1873, p. 110), and from

AMERICAN OOLEOPTERA. 39

which it differs by the totally black, coarsely and deeply punctured
head.

Collected by Mr. G. R. Crotch, at San Diego, California.

C insperatus, n. sp. — Black, moderately shining. Head sparsely and
finely punctured. Thorax subquadrate, base slightly narrowed, sides in front
arcuate, surface moderately convex, median line feebly impressed, very
sparsely punctate. Elytra less shining than thorax, finely scabrous. Body
beneath black, very sparsely punctate, sparsely cinereo-pubescent. Legs
black, punctate, with black pubescence, middle tibiae slightly arcuate, outer
spur of hind tibi« short, very stout, truncate. Length .80— .90 inch; 20—23
mm.

Ifa/e.— Antennae not stouter at middle, as long as half the body. Last dorsal
segment truncate. Fifth ventral acutely and deeply notched, sixth deeply
cleft anci fimbriate at tip. Hind trochanter with short spine near the tip.
Anterior tibiae with two spurs.

i^ema/e.— Antennae shorter than the male, gradually thicker to tip. Fifth
ventral truncate, sixth rounded at tip. Hind trochanter mutic.

This species is almost intermediate in appearance between melaena
and moerens. It belongs to Group II. of my revision (Proc. Am.
Phil. Soc. 1873, p. 1U9), by the. form of the antennae, and to the first
section of that group by the short, stout, truncate spur of the hind
tibia. The male characters will serve to distinguish the species from
any other in the group.

In C. moerens, Lee, the outer spur of the hind tibia is slender and
acute and the hind trochanter of the male angulate near the distal
end, thus approaching the preceding species.

Specimens of the above described species were taken by Mr.
Crotch, in the Mojave Desert, California.

XAMTIIOCHROA, Schmidt.

X. caliroruica, n. sp.— Form slender. Head, thorax, femora and last
abdominal segment pale reddish-yellow, body beneath, tibiae and tarsi black,
shining, elytra bluish. Front very sparsely punctured, nearly smooth, occiput
distinctly punctured. Antennae half the length of body, entirely black.
Thorax slightly longer than wide, sides in front arcuate, posteriorly slightly
sinuate, disc feebly convex, shining, very indistinctly punctured. Elytra
bluish, moderately densely scabro-punctate, sparsely pubescent and with three
feebly elevated costiform lines, two discal and one lateral, gradually evanes-
cent toward the apex. Body beneath black, shining, very sparsely punctate,
dorsal and ventral segments pale rufo-tcstaceous. Femora and base of tibi«
pale rufo-testaceous, tibiae and tarsi black. Length .38 inch; 9.5 mm.

One specimen collected by Mr. G. R. Crotch, in California.

CORPHYBA, Say.
Several new species having been brought by Mr. Crotch, the num-

ber from the Pacific region now nearly equals that from the entire
region east of the Rocky Mountains. Several present characters bo-
fore unknown, which will appear in their proper places.

Body beneath black, shining, very sparsely punctate. Legs black. Length
.28 inch ; 7 mm.

Jlfa/e.— Elytra at tip not differing from the remainder of the surface in color
and punctuation and neither impressed nor convex. Hind femora moderately
stout. Hind tibiae slightly arcuate, inner side slightly flattened and with an
oblique groove somewhat similar to that of the anterior tibiae of the Lamioid
Cerambycidos. Fourth ventral segment prolonged in a broad lobe at middle on
each side of which the margin is sinuate; fifth segment truncate at middle and
with a broad but feeble transverse channel in front of the hind margin, and in
front of this the surface is moderately convex ; sixth segment feebly promi-
nent. Terminal lobes of penis sheath slightly arcuate, obtuse at tip and not
booked on their inner margin.

Female. — Unknown. ^

This species is certainly one of the most remarkable in the genus,
and indicates a departure of specific characteristics, in a direction
wholly unexpected. Superficially it resembles punctulata. The fe-
male is unknown and probably not distinguishable without great care
from that of pumtuhita.

One specimen collected by Mr. Crotch, in California.

AMERICAN COLEOPTERA. 41

C. Crotchii, n. sp.— Head black, sparsely punctured and shining, mouth
and palpi testaceous. Antennae % moderately strongly pectinate from the
third joint, black. Thorax rufous sparsely punctured. Elytra (variable in
color?) yellowish testaceous, suture, margin and tip narrowly bordered with
black, sparsely and rather coarsely punctured and sparsely flavo-pubescent.
Body beneath black, abdomen piceo-testaceous (immature?). Legs piceous,
femora beneath testaceous. Length .20 inch; 5 mm.

Male.— Elytra at tip black, smooth and with broad shallow impression.

Female. — Unknown.

The elytra in this species may be perhaps entirely black in maturity.
It differs from every known Coiyh?/ra by the pectinate antennae
which resemble those of a Malachius.

Collected by Mr. G. R. Crotch, at Chrystal Springs, California.
C. moiltlcola, n. sp.— Head black, shining, sparsely punctured. Anten-
nas (2 basal joints) piceous. Thorax transversely oval, red, sparsely punctured.
Elytra (variable?) pale rufo-testaceous, moderately densely punctured. Body
beneath black, legs pale rufo-testaceous, tarsi piceous. Length .26 inch •
6.5 mm.

ikfa/e.— Elytra at tip either pale rufous or black, more convex, smoother, and
with a distinct but shallow impression.

Female. — Unknown.

Resembles at first sight some of the varieties of pumtulata, from
which the male characters and pale legs at once distinguish it; differs
also from elcgans by the entirely black abdomen. The elytra may be-
come entirely black except at tip in male.

California.

C. Tancbris, Horn, Trans. Am. Ent. Soc. 1871, p. 28C.

California. I have suspected that these species might be varieties
of one. Varieties of funehris with pale elytra have been brought by
Mr. Crotch and also a specimen apparently of punctulata, with a large
discal black spot on the thornx.

An examination of the penis-sheath shows, however, that while in
the former the processes at the tip are parallel and contiguous, those
of*the latter are somewhat longer and divergent. This organ appears
to vary somewhat between all the species.
C vittata, Horn, loc. cit. p. 279.

Varieties of this species may occur with the elytra entirely testa-
ceous and the suture alone broadly black. The legs may be also
entirely pale, and the antennae rufo-piceous.

Occurs at Chrystal Springs, California.

C. iilConMplcua, n. sp. — Head black, moderately coarsely butsparsel
punctured. Anteniire ^ subserrate, entirely black. Thorax rufous, sparpal
punctured. Elytra black, sparsely and moderately coarsely punctured, aui
sparsely pubescent. Body beneath and le^s black. Length .20 — .26 inch;
i — 0.5 ram.

Male. — Elytra at tip black, neither smooth, elevated nor impressed.

Female. — Elytra resembling the male.

Kesoinbles coUarls from the Atiautic Region which, however, has
the elytra of male at tip somewhat smoother and distinctly impressed.
Collected in California and presented by Mr. P. S. Sprague, of
Boston.

C. Bardii, n.sp. — Head black, front sparsely, hind angles coarsely and
densely piuu-tured. Antennae black, subserrate. Thorax rufous very sparsely
punctate. Elytra black, with oblique, narrow, testaceous stripe from the
humerus to the apex, surface coarsely and deeply and not densely punctured,
lioily beneath and leg? black. Length .22 inch; 5.5 mm.

J/«i/e.--Tip of elytra testaceous, prolonged and turned slightly upward.

Female. — Elytra normal at tip.

Collected by Mr. Crotch, at San Buenaventura, California ; dedi-
cated to Mr. Thoujas Bard, of that region.

Vj. distingiienda, n. sp. — Closely allied to the preceding species and
agreeing witli it in form and sculpture and and differs only in the elytra beinj;
entirely black (except at tip %) without oblique vitta. Length .22 inch;
5.5 mm.

Collected at San Buenaventura, California.

These two species, Bardii and dLstinguenda, differ from all the
other species in having the elytra caudate in the male. The pro-
longation is acute and turned slightly upward and inward.

The species of Corphyra may be taken in considerable numbers, at
times, on the flowers of various umbelliferous plants.

IflYCTEKUS, Clairv.

yi. qiiadricollis, n. sp. — Black, elytra luteous or piceous. Head sub-
opaque, densely punctured. Antennae pale yellow. Thorax sub-quadrate,
slightly broader than long, sides feebly arcuate, base scarcely broader, surface
moderately convex, median line vaguely defined and a feeble oblique impres-
sion on ea<!h side near the middle. Elytra oblong wider at base than thorax,
surface moderately coarsely punctured, punctures gradually finer to apex and
with minute punctures in the intervals bearing short cinereous hairs. Body
beneath black, opaque, densely punctulate and finely pubescent. Legs yel-
lowish, hind femora piceous. Lcnf^th .20 — .22 inch ; 6 — 5.5 mm.

yfale. — First joint of antennae moderately stout; second not longer than
fourth, elongated conical ; third gradually clavate, as long as the two follow-
ing together; joints 4 — 10 irregularly quadrate, flattened, gradually shorter:
joint 11 flattened pyriform. Last abdomioal segment broadly rounded at tip.

AMERICAN COLEOPTERA, 43

elightlv emarginate at middle and not concave, broadly margined with rufous.

Female. — Auteniife similar in form to the male but less flattened, joints
longer than wide and more triangular.

This species differs from the other Mycterua in our fauna by the
broader antennae of the male, the flat and emarginate last ventral seg-
ment, and the thorax not widest at base.

Specimens were collected by Mr. Crotch, at Temescal, California, on
the flowers of Agave.

The last ventral segment, in the two other species of which the
males are known, has the margin rather broadly reflexed so that there
is a moderately deep semilunar depression formed, the posterior mar-
gin is rounded in concolor and broadly truncate in scaler. The first
ventral segment at middle in the above two species is elevated in a
moderately convex umbone, which in scaber is densely pubescent, and
in concolor somewhat more convex, and in the only male before me
entirely nude. The species just described does not appear to have
this elevation of the first ventral segment.

Descriptions of New COLEOPTERA chiefly from the
Pacific Klope of North America.

BY J. L. LECONTE, M. D.

The present paper is prompted by a desire to render the collections
of Mr. Gr. R. Crotch, on the Pacific Slope of North America, available
to the subscribers and purchasers of his collections with the least pos-
sible delay. Ou examining the large number of specimens brought
back by him, as was to have been expected, many new species were
found ; descriptions of the more interesting of these have been pre-
pared by Dr. Horn, Mr. Crotch and myself, according as our famili-
arity with the respective families represented by the new species has
enabled us to do this with precision. I have availed myself of the
present opportunity to add the characters of a few remarkable or im-
portant species, partly from the Pacific, partly from other regions of
the United States, which have been added to my collection, by the
kindness of various friends.

44 J. L. LECONTE, M. D.

I trust tliat the anomalous characters and difficult position of some
of the jicncra herein dcjicribcd will absolve nie for departing', in this
iiistaiiee, from the trenerally established scientific usage of publishing
in systematic or faiinal memoirs.

TETRAGOXODERIJS Dcj.
T. lutipeniiis. — Depreiscd. greenish bronze, without lustre; porthorax
nearly twice as wide as lonj?, roundeil and sinuate on the sides, the reOexed
margin of which is pnle, moderately narrowed behind, hind angles rectangular
or neaily so, not nt all rounded. Elytra nearly twice as wide as tiie prothorax,
about one-third longer than wide, deeply emnrginate at base, much rounded on
the sides, obliquely and strongly truncate at tip; color pale, wiih small dark
spots forming a small subapical band, and limiting also a rather broad irregular
pale brow u band behind the middle: there is also a broad basal spot extended a
shtirt distance along the suture; the strife are fine, somewhat deeper towards
the li|>; the 2d and -id arc; slightly sinuous before the middle ; dorsal punctures
two, n3ar the 2d stria, the posterior one just behind the middle. Antenna palpi
and 1. gs i>ale. Length 5.6 mm; .22 inch.

Texas; Mr. Belfrage. The elytral markings are of the san)c
pattern as in T. fasiiatas and uiuhiiatus, from which it abundantly
differs by the other characters.

FOCiO-\US Dcj.
I*, parallelus.— Elongate, i)arallel, not very convex, testaceous, shining;
protliorax but little wider than head, a little wider than long, scarcely nar-
rowed and very feebly subsinuate on the sides behind, base finely margined,

marginal striaj very deep, confluent at the anterior fifth, dorsal punctures
three; scutellar stria distinct. Length 5.5 — 7 mm; .22 — .28 inch.

San Diego, California; Mr. Ulke. A singular insect, quite diflfer-
ent in form froiu all others of the genus, and suggestive of a flat
elongate Bembidium of the Peri/phus group.

The frontal striae are long and deep, the eyes uot very prominent,
tho'igh convex ; the 6th and 7th striae of the elytra are shorter and,
more obliterated in front than the others; the antennae are pubescent,
with the first two joints and half of the third shining and glabrous.
In five specimens, kindly loaned to me, I observe no tarsal differences
worthy of mention.

/*. tpznnun Chaud., is very different in appearance from the two
above described. Tt is a short, robust, convex species of metallic
blackish-green color, with the hind angles of the prothorax rectangu-
lar but not carinate, and the base, each side, with two feeble foveas.
The striae of the elytra are faint, only the inner ones being distinct,
and they are distinctly punctured in front, finer and smoother behind ;
the marginal and submarginal striae are confluent in front, but the
latter is nearly obsolete except towards the tip, wliere it is deep.
Body beneath blackish brown, legs testaceous. The general appear-
ance is that of Bradi/cellus nitiilua.

I owe my specimen of this rare insect to the liberality of Baron
Chaudoir, who. although having but two specimens in his cabinet, has
divided them with me in order to make one of them accessible to
American .students.

HYDROSCAPHA, n.g. {TTydroscnphidce.)
Head moderately large, eyes lateral coarsely granulated somewhat
transverse ; antennae scarcely longer than the head, inserted under the
edge of the front, with seven distinct joints; 1st stouter, 2d and Hd
each as long as the 1st, but narrower, 4 — 6 together shorter than 2d
and 3d united, gradually wider, 7th about as h-ng as the 2d and Hd
united, elongate oval, scarcely wider than the 6th, with an indistinct
transverse suture near the base, and another very near the tip, which
is subacute.

Labrum transverse, rounded in front concealing the mandibles.
Maxillae large at the base (lobes not examined), maxillary palpi less
than half as long as the antennae, Ist and fourth joints long, 2d and
3d united equal to either of the others, not dilated; mentura trapezoi-

d;il, nithor large, broader than lon;^, wider in front; ligula rather
larj^e, einarginute, palpi short, rather stout, 2d and 3d joints broader
and shorter than the 1st.

Prosternuui very short, hardly visible, front coxie transversely coni-
cal, contiguous, trochantin large, cavities narrowly closed behind ;
middle coxae separated, small, uiesosternuiu protuberant; metasternum
large, side pieces narrower and pointed behind, hind coxae widely
separated, laminate, the plate curved in arc of circle behind, and half
as long as the 1st ventral.

Abdomen conical with six free segments, Ist large, longer than the
four following united, which are equal in length but rapidly nar-
rower; Gth equal to the four preceding united, rather longer than
wide, concave and emarginate behind, with two anal filaments equal
in length to the segment itself

Legs short, front tibiae somewhat thickened at tip; tarsi slender,
rather shorter than tibiae, apparently -l-jointed, Ist and 2d joints
short, 3d equal to them united, 4th equal to the others united, claws
rather long and slender.

Body small, scaphiform, rounded in front, narrowed behind, convex,
elongate and shining. Head rather large ; prothorax narrower in
front, with deflexed angles, base truncate not margined. Scutellum
small. Elytra without striae, slightly punctulate, broadly truncate at
tip. Abdomen projecting somewhat behind the elytra, with three
segments visible, conical, not margined at the sides.

H. nataus. — Oval, narrower behind, convex, black or brown, shining;
head and prothorax nearly smooth, elytra sparsely and finely punctulate; an-
tennae and legs testaceous. Length less than .5 rnra ; .02 inch.

Found abundantly by Mr. Crotch, at Los Angeles in the river.
Mr. Crotch informs me that this very singular insect resembles, in ap-
pearance some of the species of Limnebms. It greatly differs from that
genus, as from all other Ili/iJrophilidse. by the laminate and widely
separated hind coxae, and by the peculiar abdomen. It seems to me
another of the synthetic types gradually becoming known to us among
the smaller and more obscure forms, connecting several different fami-
lies of the C/avicorn series; in this instance the Ni/droj)hili(lix, Scajjh-
icfiidae and perhaps the TrU-hopterygidx. In the accepted arrangement
of Coleoptera, it must be considered as indicating a new family.

SEPIDUL.UIVI, 11. g. (Hydrophilidae.)
Body small ovate convex, without lustre, prothorax greatly pro-
duced in front over the head, divided by obtuse elevated lines into
large cells; elytra costate, costas separated by two distinct rows of
quadrate punctures. Head flat, densely punctured, occiput convex
and feebly channelled ; labruui short transverse, feebly rounded in
front, mandibles small, not prominent; eyes lateral, convex, partially
divided by the canthus, not very finely granulated; palpi short, last
joint nearly conical. Antennae as long as the head, 9-jointed ; 1st
joint about two-fifths of the whole length, elongate triangular, outer
edge subsinuate, inner edge angulated beyond the middle; 2d joint
nearly as wide as the widest part of the 1st joint, rather wider than
long, 3—5 smaller, nearly equal in length, but gradually a little nar-
rower, 6th transverse, triangular, inner angle acute, 7th to 9th larger,
forming a loose club, as long as the other joints (except the scape)
united; the 8th joint is wider, and the 9th longer than the others, the
latter obtusely rounded at tip. Prothorax produced over the head
into an obtuse lobe; sides dilated and rounded in front, narrowed
towards the base; disc uneven, with large impressions and obtusely
elevated lines, the most conspicuous being a large media'i rhomboidal
impression, extending almost from tip to base. Elytra wider than
prothorax, gradually wider behind, and obtusely rounded; suture,
margin and three costoe elevated, separated by two rows of quadat.;
punctures; between the outer costa and the margin is a large tuber-
cle about one-third from the base; there is also a broad oblique trans-
verse impression behind the base, which interrupts the 2d costa.
Prosternum very short in front of the coxae which are transverse and
contiguous; middle and hind coxte also contiguous; legs roughly and
densely punctured; tibiae moderately slender, feebly d'ilated,'^without
spurs; tarsi short (hardly one-third the length of the tibise), appar-
ently 4-joiated, claws small.

The abdomen is deeply withdrawn in the cavity of the elytra; it is
fiat, and 1 can see but four ventral segments, the last is rounded at
tip, and vaguely impressed each side; there may, however, be five
segments, the 1st being invisible on account of the prominence of the
nietasternum and the contraction of the abdomen.

The genus is named in allusion to the resemblance in form of the
prothorax to that of Sepidium. The characters are altogether anoma-
lous, but seem to resemble those of H^drophiUdae. rather than any
other family, approaching more nearly perhaps to OchthrUus.

48. J- L. LECONTE, M. D.

S. COStatum. — Ovate convex, brown, opaque; prothorax produccfl ia
frt)nt over the head, dilated at tlie sides, narrowed behind, with several im-
pressions and obtusely elevated lines, at tlie miildle with a large elongate rhoin-
boidal impression ; elytra finely rugose, with suture, margin and three discoidal
costae elevated, an oblique diseoidal impression behind the base, and a large
tubercle near the side in front of the middle ; interspaces with two rows of small
quadrate punctures. Lengtii 2 n)m; .075 i)ich.

Texas; Mr. G. W. Belfruirc. Though not found od the Pacific
Slope of the continent, the characters are so extraordinary tlmt 1 have
included this species in the present paper as a proper companion to
the other singular forms which are here described.

TRIOOIVLRUS Muls.

T. Crotcllii. — Dark chestnut-brown, shining, depressed, head and pro-
thorax sparsely punctured, the latter one-half wider than long, narrowed and
rounded on the sides in front of the middle, tip emarginate, base truncate,
hind angles rectangular, disc feebly channelled with a large shallow coarsely
punctured basal triangular impression eacli side; elytra twice as long :is the
prothorax, each with six deep strongly punctured striie, the seventh is liiinler,
abbreviated in front about one-fifth from the base, and the eighth does not
reach the middle ; abdomen sparsely punctured. Length 4.5 n>n».

Vancouver Island and 8iorra of California ; under pine b;uk. The
characters of this genus, so peculiar as almo.st to warrant its estabi sh-
nient as a separate tribo, have been fully pointed out by -^Ir.
Kraatz (Ins. Deutschl. ii., 8ll5), and the question of its affinities need
not be here discussed. In comparison with the figure of the European
T. Melh/i, given by Duval (Gen. Col. Eur. ii., pi. 2:}, f 113), this
species differs conspicuously by the prothorax being transverse, and
more rounded on the sides before the middle, the color is also less
blackish and more testaceous, and the abdomen longer and narrower.

T. caelatns. — Brown, shining, depressed; head deeply punctured, trans-
verse frontal impression strongly marked, neck smooth; prothorax coarsely
and sparsely punctured, punctures n)ore dense in the triangular shallow basal
impressions, and more distant each side oi the dorsal channel, which is deep,
but does not extend to the base; behind it is a vague V-shaped impression,
sometimes obsolete ; elytra with close set rows of large punctures, which do
not form grooves or striae (as in the preceding species) ; abdomen strongly but
not coarsely punctured. Length 18 inch; 4.5 mm.

Sierras of California, under pine bark ; abundant. This species
does not differ in size or form from the preceding, but is easily known
by the much coarser sculpture. The prothorax is less transverse,
being perhaps one-third wider than long, and more broadly rounded on
the sides. It differs from T. Me.Ui/i (according to the figure above
cited), by the elytra uot wider the prothorax, and by the longer ub-
dotuen.

ate; maxillary palpi very slender, last joint more than twice as long
as the preceding; antennae not geniculated, 11-jointed, 1st and 2d
joints thicker, the 1st pyriform, the 2d globose; 3d one-half longer

little shorter, 5th longer than the two preceding united.

Z. spiuicollis. — Depressed, dull black without lustre, densely conflu-
ently punctured ; elytra with faint traces of longitudinal elevated lines; outer
Joints of antennae, palpi and tarsi brownish. Length 5.6 mm.

Vancouver Island ; in moss exposed to dripping water. The body
is entirely without lustre, except on the abdomen, which is slightly
shining and less densely punctured. I have not dissected this insect,
80 that the description of the mandibles indicates only what is seen
beyond the labrum. It belongs to the group Co^roj^liili of the
Ox^telini.

TRICHONYX Chaudoir.
T. striatns. — Chestnut-brown, shining; head with the usual deep angu-
lated impression, and two large fovese between the eyes; prothorax with a fine
dorsal groove dilated into a fovea near the tip, which it does not reach,
crossed near the base by a deep transverse groove, which is dilated each side
near the hind angle; sides much rounded in front, narrow behind the middle;
elytra wider than the prothorax, not convex, sparsely punctured, with a very
deep sub-sutural stria, two approximate discoidal strise from base for three-
quarters the length, and a short groove from the humerus; humeral plica ele-
vated; abdomen smooth, narrowly margined. Length .08 inch; 2 mm.

Vancouver Island. The antennae are stout, scarcely reaching the

base of the prothorax, with the joints rounded, 1st and 2d thicker, 3d
— 8th nearly equal, 9th and 10th gradually a little larger and trans-
verse, 11th large, oval, obtusely pointed.

TYCHUS Leach.

T. eognatns. — Dark brown, sparsely pubescent ; elytra, feet and anten-
nae paler, the latter with Joints 3 — 8 rounded, equal, ninth and tenth larger
also rounded, 11th as long as the two preceding, oval, pointed; prothor-
rax with a very small narrow fovea near the base, convex, a little longer than
wide; elytra convex, with the discoidal stria extending about half the length.
Length .00 inch ; 1.5 mm.

Vancouver Island. Of the same size and form as the Californiaa
T. tencllus Lee, but differs by the 9th and 10th joints of the anten-
nae being larger, about twice as wide as the 8th.

DERMEJ^TES Linn.
I>. signatns. — Elongate oval, convex, blackish-brown, clothed with brown
pubescence, which is more dense from the base of the elytra backwards to
behind the middle; near the base ou each is a small dark angulated mark
composed of three spots. Length .22 — .32 inch; 5.6 — 8 mm.

Widely distributed in Northern and Western America; Hudson
IJay Territory, Vancouver Island and California. Quite distinct
from D. lanhirlaa by the uniform brown color of the pubescence, and
by the finer punctuation of the upper surface; the dense pubescence
of the elytra sometimes extends nearly to the tip; in other specimens
only a little behind the middle, but in all it is prolonged on the disc
farther than at the suture and side.

TROGO DERMA L^r.

T. Rcirragoi. — Elongate, subcylindrical, black, clothed with scattered
grayish-white hairs; head and prothorax very densely, elytra less densely
though rather closely j)unotured, with two narrow undulating bands of wiiite
and fulvous hair, the 1st about one-quarter from the base, the other one-quar-
ter from the tip, base of antennse, tibiae and tarsi brown. Length .22 inch;
5.5 mm.

Texas; Mr. Belfrage, one specimen. Much more elongate than our
other species. The club of the antennae is perfoliate, composed of five
joints, and is about as long as the preceding joints united.

KAL.ISSUS, n. g. (Micropeplidce.)
Body smooth, shining, sides of prothorax broadly flattened, elytra
with two p lirs of approximate striae widely separated behind converg-
ing towards the base; abdomen conical not margined; mesosternum
moderately wide, deeply excavated for reception of the prosternura ;
metasternum with an oblique impres.sed line (somewhat as in Cocci-
nella), epimera large, visible as a triangular sp»ce at the sides behind.

AMERICAN OOLEOPTERA. 51

This remarkable insect has the form and all the essential characters
of MlcropepUdse (9-jointed antennae with solid club, 3-jointed tarsi,
widely separated hind coxse, etc.), but differs remarkably by its sculp-
ture; the elevated lines of the head, prothorax and abdomen are quite
absent, and the costae of the elytra are represented by only two pairs
of impressed lines which converge towards the base, with interspaces
becoming slightly elevated. The antennae are longer and more slender
than in Micropeplus.

The last ventral segment in the % is longitudinally impressed, the
middle and hind tibiae are bent inwards near the tip.

K.. nitidus. — Broadly oval, rounded in front, obliquely narrowed behind
the elytra; head with a triangular impression on the vertex, connected with a
transverse frontal line ; prothorax strongly narrowed in front, twice as wide
as long, rounded on the sides, bisinuate at base, bind angles not rounded, disc
smooth, very convex, sides very broadly depressed, alutaceous ; elytra with
two pairs of lines converging towards the base, interspaces costiform at the
base, but becoming flat behind; disc convex, apical margin depressed, humeri
not rounded; abdomen with five exposed segments, smooth, conical, not mar-
gined, about two-thirds as long as the elytra. Length 1.5 mm.

Vancouver Island; Mr. Crotch. On pebbly margins of a small
lake near Gold Stream, in July.

GEORYS^SUS Latr.

G. californicns.— Dull black, prothorax finely channelled, a little longer
than wide, anterior lobe separated by a more distinct transverse impression
than in G. pumilus Lee, and more deeply rugose ; elytra with rows of quad-
rate punctures which are narrower than the intervening spaces. Length .07
inch ; 1.8 mm.

California; Dr. Horn. This species is mentioned in Mr. Crotch's
Check List, from the collections of Dr. Horn and myself, but has not
been described. It is quite distinct from G. pumilus by the smaller
and more distant rows of punctures of the elytra. The last named
species has an extensive range, being found in Kansas, Canada and
Massachusetts.

THROSCINVS, n. g/ {Parnid<z.)

Body elongate oval, obtuse at each end, clothed rather densely with
short suberect pubescence. Head protected beneath by a large lobe
of the prosternum; eyes oval, rather finely granulated, not hairy; an-
tennae inserted in front of the eyes, 11-jointed, slender, nearly as long
as the prothorax ; 1st and 2d joints stouter, not longer than the 3d
and 4th united, which are slender, 5th a little wider and shorter, 6
— 10 a little wider, subtriangular, 11th oval, not longer. Palpi with

52 J. L. LECONTE, M. D.

the last joint oval, acute. Prothorax wider than lonp:, gradually nar-
rowed from the hasc forwards, transversely very convex in front, base
bisinuate. Scutolluni rather large, triangular. Elytra convex, not
wider than the prothorax, punctures fine, not arranged in rows. The
other characters present nothing worthy of record.

T. Croteliii. — Bhick with a bronze lustre, finely pubescent with short
Buberect gray hair, finely and sparsely punctulate. Length .10 inch ; 2.5 mm.
A singular insect found by Mr. Crotch, at San Diego. Differs re-
markably from Lutrochm, to which it is otherwise allied, by the
longer and slender antenna; and elongate form of body. It bears a
general resemblance to Throscns, in appearance.

ELmiS Latr.
E. (Iivor$;cns. — P]longate oval, dark green-bronzed, finely pubescent :
prothorax one-half wider than long, gradually narrowed and rounded on the
aides from the base, disc convex distinctly punctured, basal lines extending as
far as the middle, slightly divergent outwards, base emarginate in front of the
scutellum, not fovcate; elytra elongate scarcely wider than the prothorax,
nearly jtarrllel on the sides and strongly margined, disc convex, striae com-
posed of close set quadrate punctures, scarcely finer at the apex, interspaces
obsoletely punctulate; tarsi brownish. Length .10 inches; 2.5 mm.

California; Mr. Crotch. Narrower than E. ovalis, with the sides
of the elytra nearly straight; quite distinct from all other species
I have seen by the basal lines of the prothorax diverging outwards.

E. corpiilentus.— Ovate, convex, thinly and finely pubescent, greenish-
black ; prothorax somewhat wider than long, feebly channelled, scarcely punc-
tulate, narrowed and rounded from the bnse. front angles dellexed and broadly
impressed, basal lines extending to the middle, very deeply impressed, not
divergent, base emarginate in front of the scutellum, not foveate. Elytra
wider than prothorax, very convex behind, much rounded on the sides, strise
deep, j)unetured in front, finer and less punctured behind ; interspaces feebly
j)unctulate. Length .10 inch ; 2.5 mm.

British Columbia; Mr. Crotch. In one specimen the elytra
have abroad basal band and large apical spot yellow; the antenna)
joints 1 — 8 and the legs are also testaceous.

E. seriatus. — Elongate oval, black with a greenish reflection; prothorax
wider than long, distinctly punctured, narrowed, and feebly rounded from the
base, basal lines extending to the middle, with a fovea near the anterior ex-
tremity of each, base with two small foveae near the seutellar emargination.
Elytra scarcely wider than the prothorax, nearly parallel on the sides, not very
convex, striae composed of oval rather distant punctures, interspaces obsoletely
punctulate; a largo indistinct subhumeral yellowish blotch extends to the
sides but not to the suture, last joint of tarsi yellowish. Length .075 inch;
1.8 mm.

AMERICAN COLEOPTERA. 53

Oac specimen, California; Mr. Crotch. Narrower than E.
4:-maculatus Horn, and quite diflPerent by the elytral striae not im-
pressed and more distantly punctured.

E. fovcatus. — Elongate, black; protborax longer than wide, feebly nar-
rowed in front, subsinuate on the sides, discoidal lines entire sinuate, disc
with a deep oblique impression, a broad transverse one and a large medial
fovea; elytra with striae composed of large approximate punctures, 4th and
6th interspaces feebly carinate, the former extending three-quarters the length
of the elytra. Length .08 inch : 2 mm.

Two specimens without locality collected by Mr. Crotck. Allied
to E: pmdhi'i Lee, and similis Horn, but differs by the less strongly
carinate elytra. It is also a larger and less elongate species with the
medial fovea of the protborax more distinct from the transverse im-
pression.

E. vulneratns. — Rather stout, brownish-black, slightly pubescent; pro-
thorax feebly punctulate, scarcely longer than wide, slightly narrower in
front, broadly rounded on the sides, discoidal lines entire, posterior impressions
nearly transverse, scarcely oblique, feebly separated at the middle, base bi-
foveate near the scutellum ; transverse impression deep entire, disc in front
convex; elytra at base wider than the protborax, sides nearly straight, tiien
obliquely narrowed and slightly prolonged at tip, striiB rather finely punc-
tured, interspaces sparsely punctulate, 4th and 6th finely carinate; antennae
and legs dark testaceous. Length .08 inch ; 2 mm.

Texas; Mr. Belfrage. One specimen. Not quite so stout as E.
ovdlis, but nearly so.

E. caesus. — Elongate, parallel, testaceous, shining, slightly pubescent;
head somewhat darker, protborax scarcely longer than wide, nearly smooth,
sides finely crenate, nearly straight in front; rounded near the hind angles,
discoidal lines not very deep, obliterated in front, transverse impression very
deep, disc convex before and behind; elytra very little wider than the pro-
thorax; striae composed of large punctures, becoming smaller and obliterated
towards the tip, 6th interspace scarcely carinate. Length .03 inch; 1..3 mm.

Texas; Mr. Belfrage. A very distinct species of uncommonly
small size.

PACIIYPIiECTRUS, n. g. {JT//bosorini.)
Body ovate, convex, sides and under surface setosa with long erect
hairs, above smooth and glabrous. Mandibles broad, outer edge
sharp, not rounded but obtusely angulated, lubrum short rounded in
front. Antennae with the 1st joint of the club completely surround-
ing the others; eyes not divided, mentum not eraarginate; head with
a broad sinuated transverse impression and a frontal tubercle; pro-
thorax wider than long, narrower in front, nearly smooth, finely mar-
gined at tip, sides and base; elytra very convex, gradually a Utile

wider than the prothorax, thou obtusely rounded ; smooth with a deep
sutural stria and two raarjijinal striae which are abbreviated in front,
the inner one being fainter and shorter. Legs very stout, front tibise
three-toothed, not serrate ; middle and hind tibiae thick, with the
transverse crest and apical margin well developed ; spurs of middle
tibiae long, of the hind pair short, broad and obtuse, the outer one
being the larger. Tarsi, front as long as the tibiae, slender, joints 1 — i
equal ; middle shorter than the tibiae, joints 1 — 4 decreasing a little in
length; h^nd pair only half the length of the tibiae, stouter, joints 1
— 4 slightly decreasing in length; claws slender, simple.

I*. lne%'is. — Chestnut-brown, shining; head with a frontal tubercle an(i
transverse broad impression; prothorax and elytra smooth, the latter with a
deep sutural and two marginal striae; margins of body, under surface and leg*
clothed with long erect hairs. Length .26 inch; 6.5 mm.

One specimen, Sta. Barbara, Califjrnia; Mr. Crotch. Remarkably
different from all the species of the tribe thus far described by the
absence of the elytral rows of punctures.

PEI.IDNOTA M'Leay.
I*, liigubris. — Black, with a feeble metallic tinge; prothorax sparsely
punctured, more finely ami densely towards the sides, which are rounded
narrowed in front of the middle, but only slightly so towards the base, angles
rectangular, slightly prominent; elytra dull, finely alutaceous, with scarcely
perceptible traces of distant rows of punctures. Length .7 — .9 inch; 17.8 —
22.7 mm.

%. — With the front tarsi thickened, the inner claw dilated at base, and the
club of the antennoe longer.

Arizoiia; Mr. C. V. lliley; also in the collection of Mr. Ulke.
Related to F. Lucae, but quite different by the nearly black color, the
more finely punctured prothorax, which is less rounded on the sides,
and less narrowed towards the base, and finally by the rows of punc-
tures on the elytra being almost obliterated. The head is alike in
both species, densely punctured, with the clypeus narrowly margined,
and at the tip subtruncute, a little more distinctly so in the present
species.

<RE:.n.i^iTO€IIIL.i;S Knoch.
C. retractns. — Browmsli-black, not shining; prothorax wider than long,
coarsely punctured, narrowed in front, broadly rounded on the sides, foveate
inside of the front angles, fovese not extending to the apical margin, hind an-
gles suddenly and strongly retracted, acute, surrounded by a deep grooTe;
elytra flattened, with the usual sculpture of large shallow punctures, not
closely placed. Length .44 inch; 11 mm.

Texas; Mr. Belfrage. One specimen. The mentum is deeply and

AMERICAN COLEOPTERA. 55

broadly incised behind. This species is allied to C. canalieulatus, but
the prothorax is more convex, the foveas adjacent to the front angles
do not extend to the apical margin and the hind angles are much re-
tracted, so that the base is fully one-fourth narrower than the middle
of the prothorax, as in C. varidosits^ to which it in other respects
has no resemblance.

C crinitns. — Brownish-black, not shining, thinly clothed above with
very long yellowish hairs; prothorax rather flat, very coarsely punctured,
sides rounded, subsinuate towards the base, hind angles rather large, elevated,
smooth, circumscribed by an impression, inside of the front angles is a fovea
extending to the apical margin; elytra flattened, with the usual sculpture and
traces of broad longitudinal grooves. Length .5 inch ; 13 mm.

One specimen, Utah? The mentum is obtusely pointed behind,
and not incised- This species is related to C. Knochii, but the larger
hind angles of the prothorax, the more broadly rounded sides, which
are distinctly creuate. the less convex disc, and ^bove all the lono'
hairs distinguish it at first sight. The legs are as in G. Knochii.

SCAPTOL,EWUS Lee.
S. estriatus.— Brown, pubescent, hairs on prothorax, base of elytra and
breast longer; elytra rather finely and densely punctured, without any
appearance of striae. Length .5.3 inch; 13 mm.

One immature specimen from Texas. Very different from S. Le-
contei Salle ( /emoralix | Lee), by the elytra having no vestige of
striae; otherwise it resembles that species, but is smaller, with the
prothorax broader and the 3d joint of the antennae more than one-
half as long as the 4th.

In the Mexican S. femnrali^ the elytra are striate, but the protho-
rax is still broader and much more rounded on the sides, and the 2d
and 3d joints of the antennae are nearly equal, together a little more
than one-half as long as the 4th.

BBACHYPSECTRA, n. g. {Rhipiceridm.)
Body elongate, rather flattened, shining, punctured and pubescent;
elytra strongly margined, feebly striate; head moderate, front convex,
and mouth inflexed ; labrum smaP, mandibles not prominent, palpi
small and slender; antennae inserted in triangular excavations, not
distant, U-jointed, joints 1—4 subequal, 3d a little longer, 5—10 tri-
angular, transverse forming a serrate elongate mass, 11th larger, ap-
pendiculate, eyes large, oval, finely granulate ; prothorax transverse,
trapezoidal, side margin distinct, hind angles acute subcarinate ; pros-
ternum broad, feebly rounded in front, distinctly prolonged behind

the coxae, inflcxcd and received into the excavated mesosterum ; front
coxae transverse, without distinct trocliantin, side pieces of nieso-
sternum extending to the coxae, which are subquadrate, not promi-
uetit and separated by the narrow nicsostcrnuni ; side pieces of lucta-
sternum rather wide, parallel; hind coxre extending nearly to the
side margin, narrow, feebly sulcate behind, coxal lamina almost ob-
literated; abdomen with five free and equal ventral segments j legs
slender, spurs very small, tarsi as long as the tibiae, slender, last joint
without onychium, claws simple; epipleurae narrow, extending to
the apex ; scutellum rather large, rounded behind.

A genus of difficult position, having a general resemblance to
Zenoa, but somewhat broader, with the mouth more inflexed, and the
mandibles smaller. It differs, moreover, from the other genera of the
iamily to which I have referred it, by the absence of onychiuu), and by
the trochantin of.thc front coxae being indistinct. It also differs more
essentially by the prostcrnum being prolonged behind the coxce, into
an inflexed point received into an excavation of the mesosternura. It
cannot be referred elsewhere in the series, unless it be to the tribe
Euhriini of Dasc^flidse, to the species of which it has no resemblance
in appearance, nor in the more special characters.

B. fulva. — Yellowish-brown, shining; head punctured, feebly channelled,
transversely impressed betv/een the eyes; prothorax transverse, trapezoidal,
punctured, feebly channelled, hind angles prolonged, acute, subcarinate;
elytra slightly wider than the prothorax, strongly margined, punctured, feebly
striate, obtusely rounded behind ; beneath shining, finely punctured and pubes-
cent. Length .20 inch; 5 mm.

Texas; Mr. Belfrage. No sexual differences observed.

AKAEOPUS, n. g. {Dasa/ltidce.)
Body elongate, oval, convex, rather acute before and behind, finely
punctured, densely clothed with prostrate hair. Head dcflexed, mod-
erate in size, front convex, with the transverse suture distinct,
epistoma entirely corneous. Mouth rather prominent; labrum con-
vex, broader thafl long, rounded and feebly emarginate in front.
Mandibles curved, acute at tip, visible beyond the labrum. Antennie
inserted upon the front at the sides behind the base of the mandibles,
but not under a prominence, 1 l-jointed, rather stout, extending a
little beyond the base of the prothorax, subserrate; 1st joint stout,
shorter than 3d; 2d globose, 3d subtriangular a little longer than the
4th ; 4 — lU equal in length ; 11th a little longer; eyes rounded, finely
granulated; maxillary palpi not dilated, last joint a little longer;

AMERICAN COLEOPTERA. 57

labial with last joint somewhat triangular; mentum large, trapezoidal.
Prothorax wider than long, very much narrowed in front, rounded
and overhanging the head at tip, rounded on the sides near the hind
angles, which are acute; base bisinuate. Scutellum . rounded, con-
cave. Elytra a little wider at base than the prothorax, rounded at
the base, slightly enlarged for two-thirds the length, then obliquely
narrowed; side margin distinct, wider towards the tip; strife faint,
the sutural deep towards the base. Prosternum narrow, prolon^'ed
-behind the coxae, and received into the mesosternum, which is trian-
gularly incised in front and rather narrow between the coxte. Front
coxas transverse, prominent, with large trochantin; middle coxte with
narrow trochantin extending to side pieces; hind coxse laminate,
gradually dilated inwards. Abdomen with the 1st ventral shorter and
the 5th longer than the others which are equal. Legs slender tarsi
not lobed, a little shorter than the tibiae, joints 1—4 equal, 5th equal
to the three preceding united, claws simple, onychium not visible.

Were it not that the front coxae and insertion of the antenna; for-
bid, this insect would be referable to the Eucnemidse, to which family
it has much resemblance in appearance.

The afiSnitijs are of course with Lichas and Stenocolus. From both
it diflfers by tha more convex front, the less elongate and less serrate
antennas, the more prominent front coxae, the less prolonged excava-
tion of the mesosternum and the 1st ventral segment much shorter ;
it differs besides by the prothorax being produced over the head, and
not margined at the sides. In Lichas moreover the onychium is con-
spicuous, and in Sfenocolus there is a series of smooth oblique scars
on each side of the ventral segments.

A. monachus.— Blackish-brown, densely clothed with short yellow-
brown pubescence, very finely punctulate; prothora."! with two round basal
fovese, between which the base is depressed; elytra faintly punctured in stria,
sutural stria deep for one-quarter the length from the base. Length A inch;
10 mm.

Oregon; Lord Walsingham. The basal fovese of the prothorax
are nearer together than to the sides.

DICRANOPSELAPHIJS Gue'rin.
D. E<lwar<Isii.— Broadly ovate, not very convex, finely pubescent,
black; elytra testaceous with feeble grooves which are irregularly punctured,
interspaces as wide as t.he grooves, nearly smooth; prothorax bisinuate at
base, much wider than long, sides and tip rounded in the arc of a circle, mar-
gin concave, reflexed, transparent and white along the front as far as the mid-
dle ; scutellum large, black; legs brownish testaceous; antennae black,
second joint very small. Length .22 inch; 3—4.3 mm.

Found abundantly by Mr. Crotch, at Santa Barbara, flying about
buishes near a stream. Of" thirty-three individuals before me thirty
arc lualcs and only three females. The larva is subaquatio, and ac-
cording to Mr. Crotch resen)bles in appearance those of Piiej)hcii us and
Jlelichns. I have adopted the name aflS.Kcd to the species by Mr.
Crotch in honor of Mr. Henry Edwards, of San Francisco.

MICROPIIOTUS Lee.

.W. ail^^llKtllS. — Elon2;ate, brown testaceous, elytra darker, roughly and
densely punctured, elevated lines distinct, sides concave and broadly rnar-
gined near the buse; scutelluin and prothorax pale, the former channelled,
the latter rough longer than wide, truncate at base, rounded in a semiellipse
on the sides and tip, disc broadly conve.^ in front, margined very broadly at
Uxii sides, and more narrowly at the tip. Length ."28 — .4 inch ; 7 — 10 mm.

tal segment with slender lobes.

9- — Eyes small, distant, head narrow, palpi less elongate; antcnnrc 8-jointed
with a small terminal subulate protuberance; elytra enlirely wanting, the
scutum of the mesothorax being an undivided plate; apical process of last
ventral short.

Mariposa, Oregon ; Dr. A. Thevenet. This species though much
narrower in form, is similar in sculpture to M. dilatatm Lee, from
Lower Califdrnia. The fjn)ale of the last named species is unknown,
60 that the discovery of that sex in the present instance is more im-
portnat. The difference in the number of antennal joints is a remark-
able and hitherto unknown character in the family.

MATIIETEUS, n. g. {Lampyridcc.)

Body not convex, rather Lyciform, above confluently punctured,
strongly margined. Head concealed under the prothorax, short and
broad, eyes distant, convex, moderate in size, finely granulated ; an-
tennye inserted just in front of the eyes, distant, 11-jointed, strongly
pectinate, 1st joint triangular, hardly longer than wide, 2d shorter, as
wide as long, 3d triangular, inner angle acute ; 4 — 10 triangular, each
with an internal process as long as the joint and arising about the
middle, or beyond the middle; 11th joint flat, acutely sinuate near the
tip, which is also acute. Front concave behind the antennae, convex

tinctly separated from the front. Mandibles acute ; palpi moderate,
maxillary longer, last joint subtristngular obliquely rounded at tip.
Prothorax transverse, lateral and apical margin very wide and re-
flexed, irregularly rounded, base broadly rounded, hind angles obtuse,
rounded. Scutellum triangular, small, rounded behind. Elytra with
rounded humeri, wider from the base for thi-ee-quarters the length,
then broadly rounded, disc rather flat, with four narrow elevated
lines, suddenly declivous near the humeri, side margin broad and re-
flexed ; epipleurse wide. Front coxae conical contiguous; middle
coxae quadrate, not large, contiguous; hind coxa3 narrow, transverse,
contiguous. Legs slender, not compressed, trochanters on the inner
side of the thighs, tarsi with the joints 1 — i gradually shorter, 3d and
4th slightly lobed beneath, not emarginate, 5th slender, claws feebly
dilated near the base. Abdomen ( 9 ) with seven ventral segments,
7th smaller, rounded at tip; last dorsal broadly rounded at tip; geni-
tal segment not prominent ; no phosphorescent spots.

A singular genus, which must be placed probably near Calyptoce-
phalas, but differing from it as from all Lawpijrhii by the widely dis-
tant antennoc, broader mouth and better developed labrum.

M. Theveneti. — Black, without any tinge of brown; prothorax anrl
.elytra dull orange, the former with two approximate smooth spots, occupying
the disc, and sej)arated by a narrow dorsal channel, margin punctured ; elytra
densely and roughly punctured, with four fine elevated lines, the third of
which commences on the humerus which is very prominent. Length .45
inch ; 11 mm.

pubescent and scabrous, as long as the abdomen, rounded at tip, not dehiscent,
fides with narrow reflexed margin. Length .05 inch j 11 — 10.5 mm.

California. I have seen several males of this species, which resem-
bles in all characters, except the length of the elytra, our two Eastern
species. The labrum is, however, more suddenly and deeply emargin.
ate, and the seventh ventral is rather cleft than emarginate, with u
short obtuse process at the base of the cleft.

9f.4.STINO€ERUS Solier.
j?I. texanns. — Testaceous, abdomen dusky except at tip, opaque pubes-
cent; head as wide as the prothorax, finely and densely punctured; prothorax
a little louger than wide, front angles rounded, hind angles rectangular, finely
and densely punctured; elytra one-third as long as the abdomen, dehiscent,
rounded at tip. Length .25 inch; 6 mm.

60 J. L. LECONTE, M. D.

Texas; Mr. Bclfrapfe. Female unknown. Varies of a blackish
color with the occiput anJ tip of abdomen testaceous. After examin-
ing the type of Mastlnocerua, in the Paris Museum, I see no reason
for .separating this as a distinct genus. In the Chilian type the last
joint of the antenncc has been broken off, and the 10th joint, by want
of sufficient care has been regarded as the last joint, which has been,
therefore, absurdly described as bifurcated, a form which I am. free
to say that our present knowledge leads us to 'believe does not exist
in Coleoptera. In the Texan species above described the antennae
are 11-jointed, the 1st joint as long as the 'lA and 3d, which are sim-
ple, the j)ints -1 — 10 slightly increasing in length, each with two
long basal hairy cylindrical processes, about three times as long as the
joint itself ; 11th joint simple, as long as the branches of the lOth
joii.t ; maxillary palpi nearly as long as the head, last joint large,
moderately dilated with the palparium elliptical; eyes large, finely
gninulated. The seventh ventral segment is eniarginated almost to the
base ; the last dorsal is subtruncate or broadly rounded, with two
shallow longitudinal furrows.

SIL,IS Charp,
The following table will enable the species of this genus to be easily
distinguished; 8 and 9 miy be perhaps variations in color of one
species.

cavity near the base; both angles of the excavation acute; ante basal ap-
pendage acute, spinifonn I. »»pinigera.

therefore not very distinct, though acute, anterior margin of excavation
sinuate with two prominent rounded angles; ante-basal appendage
acute, spinlform, directed obliquely backwards.
Basal excavations of prothorax moderate, (color black, disc of prothorax yel-
low) .• 2. difticiiis.

Basal excavations of prothorax larger (elytra and prothorax pale).

are therefore more prominent and acute ; incisure near the base moder-
ately deep, with the anterior angle rounded; ante-basal process com-
pressed, rounded at tip.
Basal impressions of prothorax very deep, hind angles strongly cariuated
(upper surface pale).

Basal impressions of prothorax much smaller; hind angles feebly cariaaled ;
(black, prothorax more or less yellow).

AMERICAN COLEOPTERA. 61

Incisure of hind angles deep, appendage long fi. pcrcomis.

Incisure of hind angles shallow, appendage short 7. Tulnerata.

tirely lateral, anterior angle of incisure nearly rectangular, hind angle long,
acute, produced into a slender filament which is bent forwards.

Elytra and prothorax pale, the latter sometimes with a black vitta.

8. Iiifoa.
Black, prothorax yellow, sometimes with a black dorsal vitta... 9. filigera..

S. »<>pinigera. — Elongate, testaceous, head, antennae, elytra towards the
tip, and legs more or less dusky; prothorax smooth, shining, wider than long,
convex, strongly margined, deeply excavated and emargina'te each side near
the base, angles before and behind the emargination acute ; armed in addition
with a slender sharp spine near the hind angles; elytra finely scabrous and
pubescent; antennae with the 2d joint small, 3d equal to the 4th. Length .28
inch ; 7 mm.

One % Oregon. The basal excavations of the prothorax are large,
deep and rounded.

S. flavida. — Elongate, black, prothorax, elytra and feet yellow, the
former nearly twice as wide as long, sides straicjht oblique, front margin
broadly rounded, feebly reflexed, disc convex, hind fnargin blackish strongly
d3pressed and reflexed, deeply foveate each side; hind angles very deefily in-
cised, anterior process narrow acute; elytra du^ky towards the tip and sides,
finely not deeply punctured; tarsi and hind thighs dusky; antennae black
( '^ ) as long as the body, 2d joint small, 3d and following ones equal. Length

Two % , California, at Lake Tahoe. Similar in appearance to S.
pallida, but quite different by the deep incisure of the hind angles of
the prothorax ; penultimate ventral segment, as usual, deeply and
widely emarginate.

S. cava. — Elongate, pale testaceous, prothorax much wid^r than long,
sides oblique, deeply emarginate near the base, angle in front of emargination

S. vnlncrata. — Less slender, black, prothorax strongly margined, broad-
ly rounded on the sides, broadly excavated each side at the base, emargination
not very deep, angle in front obtuse, basal angle obliquely earinate, pmcess
short and rounded; disc feebly channelled with a reddish-yellow round spot
each side; elytra finely scabrous and pubescent; antennae short, 2d joint
small, 3d equal to the 4th. Length .25 inch ; 6 mm.

G2 J. L. LECONTK, M. D.

One % , Orcjion. Very distinct by the short obtuse process of the
hind angle of the prothorax.

W. liiteit Lee, Joiirn. Acad. Nat. Sc. 2d, v. 33) ; pollens || Lee, Proo. Acad.
Nat. Sc. Phila., v. 3:59.

This species which has been incorrectly placed as a. synonym of iS.
pallida Mann, is smaller and different by the anteunae being stouter,
and the process of the basal angle of the prothorax longer filiform
and bent jnst as in S. Jr/i(/rra.

S. pallida Mann, differs essentially by the basal excavations of the
prothora.K being separated from the emargi nation by an elevated ob-
liipie line which runs to the hind angle so as to render it carinate ;
the angle in front of the emargination is obtuse and the jjrot-e.ss be-
hin 1 the einargination is very near but separate fronj the .small hind
angle, compressed, deflexed and curved ; sides broadly rounded. The
antennae are slender.

S. liligera. — Elongtite, black, protliorax bri^Iit yellow, shining, very con-
vex, HiKjly sp.irsely [)unctiihite, strongly cliannelled, twice as wide as long,
apical margin roiuided. strongly rellexed, basal margin deeply excavated and
strongly retlexed: hind angles incised, anterior process not truncate, hind
jtrocess fili(brin, suddenly bent forward; elytra more strongly punctured ; an-
tenn.-B ( 'J) ) as long as tiie body, 2d joint small, 3d nearly as long as the 4lb.
Length 3.0 mm.

One S , Santi Barbara, California. Narrower than S. percnmis
and quite different by the prothoraeic characters. A specimen from
Vancouver which <l refer to this species has the front and hind mar-
gins and djrsal spot of the prothorax black.

l>ITEM»fUS Lee.

I>. oUtusitS.— Robust, black, prothorax twice as wide as long, smooth,
sides rounded and sinuate, red, margins blackish, strongly reflexed ; elytra
rather finely scabrous, punctured; antennce feebly serrate, 2d joint short, 3d
equal to the following. Lengtli 4 mm.

%. — Sides of the prothorax suddenl}' rounded, deeply incised near the base,
anterior process obtuse with a small cusp projecting backwards, posterior pro-
cess rounded at tip, base excavated each side, medial part forming a lobe more
suddenly limited than in D. bidentatus ; antennae two-thirds as long as the
body.

9.. — Sides of prothorax less suddenly rounded, subangulated and feebly
sinuate near the base, which is not lobed, bind angles obtuse, rounded ; anten-
nsB one-half as long as the body.

Los Angeles and Saucelito, California. liarger and more robust
than D. bidctifatua, and remarkably different by the sides of the tho-
rax being rounded and the anterior process obtuse.

TRICHODES Herbst.

T. bimacillatns.— Dark blue, pubescent with long, soft, erecl^yellow
hair; prothorax convex, rugosely punctured with an indistinct dorsal line;
elvtra thickly but not deeply punctured with a few faint traces of strise near
the suture and a bright orange round spot about the middle near the side ; an-
tennsB black. Length .4 inch j 10 mm.

Califoi-Dia and Oregon. This species has become quite frequent in
collections within the last two years. It is quite distinct from T. or-
natas by the prothorax more convex, less constricted in front, less
narrow behind, punctured and not shining. It is in these respects
more allied to T. Nntalh Kirby, and may perhaps be an extreme
variation of this species. Until intermediate forms occur it will be
better to distinguish it by a separate name.

L,EB.4.SIEl,L..4. Spin.

Li. Jiiaculicollis.— Dark blue, clothed with erect black hairs; prothorax
a little longer than wide, oval, convex, finely and sparsely punctured, shining,
red with a large disooidal black spot reaching the tip but not the base ; elytra
coarsely and thickly punctured. Length .2 inch; 5 mm.

Mariposa, California; Dr. A. Thevenet. xMore elongate than L.
jaiithina and quite distinct by the color of the prothorax which is
lunger and less punctured. The antennae are testaceous with the last
four joints black; the legs seem to be brown.

IlEDOBIA Latr.

H. granosa.— Dark brown, clothed with coarse cinereous pubescence, be-
coming brownish at the middle of the prothorax, which is compressed and ele-
vated at the middle near the base; elytra densely granul.ite-punctate with
scattered distant, small, smooth granules; behind the middle there is on each
elytron a small angulatcd spot with less dense pubescence; scutellum very
densely pubescent. Length .17 inch; 4 mm.

California. The prothoracic elevation is suddenly declivous and
almost perpendicular behind.

XESTOBIIJM Motsch.
X. alfine.— Elongate, blackish-brown, very densely and finely pnnctulate,
clothed with yellowish-brown short pubescence, ^which in well preserved
specimens is probably uniform), disc of prothorax not channelled, sides not
strongly flattened. Length SA inch; fi mm.

Vancouver and California. Resembles in form X. tenselatum, but
quite different by the finer punctuation, the less broadly flattened
sides of the prothorax, and by the puboscence being much finer and
not arranged in tufts ; the last three joints of the antennae are only
one-hilf longer and wider than the 8th joint, and the 2d— 8th are
much more slender than in X. tesseiatuni.

64 J. T.. LECONTE, M. D.

Another species of this genus was given me by 3Ir. E. P. Austin,
which may be here added, in order to avoid multiplication of refer-
ences.

X. W(liiali*Iiini. — Blackish-brown, very densely granulato-punctate, ir-
regularly clotlieil with spots of yeMowish-brown pubescence; prothorax not
channelled, siiles widely inari^iiied, last joints of antennae as long as the 6 — 8
ui»ited, and about twice as wide as the 8th. Length .19 inch; 4.fi mm.

Providence, llhode Island; two specimens. Much smaller than
X. tesselafum, but similarly punctured and pubescent; the prothorax
is, however, not at all channelled and the last joints of the antennm
are much larger.

VKILLKTT.A, ». g. {Anobiini.)

The front cox.tb in this genus are contiguous and the prothorax ex-
cavated beneath for the reception of the head, and the antenujc 11-
jointed, in repose received under the head, as in the other members of
the group Xyletini (lite. Proc. Acad Nat. Sc. Phila., 18G5, 2»7) ; the
mesosteriium is not advanced bet^veen the middle coxa;, but is as
in Xyletinus. It differs, however, conspicuously from that genus by
the antennae.

These organs have the 1st joint of moderate size somewhat dilated,
about two and a half times longer than wide; 2d ovate, as long as
wide; 3 — 8 triangular, broader and gradually transverse in % form-
ing an acutely serrate funiculus; 9 — 11 longer, flat, each as long as
the three of the preceding ones. The elytra are striate as in Xyleti-
nus, with a long scutellar, ten dorsal and two short lateral striae occu-
pying the post-huujeral expansion of the elytra, which is as well
n»arked as in Xyletiuus; the tip is feebly truncate and broadly
rounded.

V. Miirrayi. — Elongate, cylindrical, black, covered with very fine short
cinereous pubescence; prothorax ferruginous with abroad black apical band,
si^ margin broadly rellexed, disc convex, base margined each side near the
hind angles, .which are rounded ; elytra with fine impressed scarcely punctured
Btrise, each with a ferruginous spot in front of the middle. Length .32 inch;
8 mm.

One % , California, given me by Mr. A. Murray. The prothorax
is finely punctured and the interspaces of the elytra nearly flat.

V. expAiisa. — Blackish-brown, elongate, cylindrical, covered with fine
abort sericeous pubescence; prothorax feebly channelled, with side margin
very widely reflexed, extending upon the sides of the base, disc convex finely
punctured; elytra with the strioe line, but deeper and more distinctly punc-.

AMERICAN COLEOPTERA. 65

tured and more oblique towards the base, tip more broadly subtruncate and
rounded. Length .25 inch; 6 mm.

California; Mr. Crotch.

V. convexa. — Blackish-brown, elongate cylindrical, covered with fine
sericeous pubescence; prothorax more distinctly punctured, convex, side mar-
gin much narrower; elytra with the strise deeper, distinctly punctured, more
oblique towards the base, interspaces convex. Length .28 inch; 7 mm.

California; Mr. Ulke and Dr. Thevenet. Differs from the two
preceding by the narrower side margin of the prothorax and wore
convex elytral interspaces. One specimen has the elytra testaceous
with dusky sides ; it is probably not quite mature.

EUCERATOCERUS, n. g. {Ptilinini.)

Body cylindrical, clothed with fine subsericeous pubescence, very
finely punctulate, elytra with very indistinct fine strias. Head
rounded, not received into the prothorax beneath, eyes rather large,
finely granulated, not very prominent; palpi rather long, as in Ptili-
niis, but a little stouter, last joint elongate oval ; antennae with the
1st joint nearly as long as the 3d, 2d small, 3d ani following sub-
equal, about three times as long as wide, each with an oblique basal
process longer and as broad as the joint itself, except that of the 2d,
which is shorter and broader. Legs slender, tarsi longer than the
tibise, Ist and 2d joints long, 3d and 4th small, 5th as long as the two
preceding, claws small, distant.

A singular genus, closely allied to Ptilinus, differing chiefly by the
form of the antennae, the larger and less prominent eyes, and the
longer and more slender tarsi.

E. Hornii. — Cylindrical, elongate, dark piceous, clothed with fine gray
pubescence producing a leaden lustre; elytra with very fine indistinct punc-
tulate strise; anteunse and legs a little less dark in color. Length .25 inch;
4 mm.

One specimen, Texas ; Mr. Belfrage. The antennae are more than
half the length of the body, the 10th and 11th joints are unfortun-
ately broken off.

It gives me great pleasure in the name of this very interesting ad-
dition to the fauna, to express my appreciation of the excellent labors
of my friend. Dr. G. H. Horn, in investigating the Coleoptera of the
United States.

P0L.YCA01V Lap.
P. plicattlS.— Black, shining, thinly clothed with long erect yellowish
hairs; head large, very densely and finely granulato-punctate, granules be-

coming less dense behind ; prothorax as wide as long, convex, finely punctured,
slightly narrowed behind, sides nearly straight, disc transversely impressed
anti feebly channelled; elytra very coarsely and sparsely punctured, eacli
with a series of short very deep oblique grooves midway between the suture
and side margin, posterior declivity oblique, flat, smooth, strongly margined
with an elevated rim, suture also elevated behind; abdomen ferruginous^
densely pubescent; labrum fringed with bright fulvous hair. Length .48
inch ; 12 mm.

One specimen, Texas; Mr. Belfrage. Very distinct by the pe-
culiar sculpture of the elytra. The grooves extend about one-fourth
the width of the elytra, and are wider than the interspaces between
them, and very deep; they are from twelve to fifteen in number; the
posterior declivity of the elytra is margined for almost its entire
length, while in P. exesiis the margin extends about one half the
length of the slope, forming only a semicircle with that of the oppo-
site side.

P. obliqillis. — Black, thinly clothed with long erect yellowish hairs;
head large, granulate; prothorax densely punctured, convex, feebly chan-
nelled, slightly narrowed behind, sides straight, rounded near the tip; elytra
coarsely punctured, posterior declivity strongly margined for two-thirds the
length, and suture elevated behind. Length .45 inch; 11. .5 mm.

One specimen, Texas; Mr. Belfrage. Allied to P. exe^ux^ with the
punctures of the elytra less coarse, not arranged in rows and with the
margin of the posterior declivity much longer, forming about two-
thirds of an ellipse j the punctures also become smaller towards the
tip.

PIIYM4TOI>E.S Muls.

P. nitidim. — Black, very shining, sparsely punctured, thinly clothed

with long erect hairs; elytra with two transverse ivory-white slightly elevated
fascise; base of elytra, legs and antennae more or less brown; joints 1 — 6 of the
latter with flying hairs. Length .24 inch; 6 mm.

California. The eyes are deeply emarginate, though less so than in
P. (hcHssatiis. This species dififers remarkably from all others in our
fauna by the highly polished surface and sparse punctuation.

HYBODERA Lee.
II. flebiliiii. — Blackish, finely punctulate and clothed with fine prostrate
pubescence with two patches of silvery lustre, one oblique near the base, the
other transverse behind the n)iddle; prothorax longer than wide, lateral and
dorsal tubercles very feebly developed. Length .25 inch ; 6 mm.

California. Smaller than H. hiherculata Lee. (New Spec, 191),
and more slender, having the general proportions of Gracilia j)i/ff-

mnea ; the thoracic tubercles are not prominent, the antennae of the
9 are as long as the body; of the S a little longer.

Larger series of specimens will probably prove that this is only a
badly developed form of the species above mentioned. For the
present, however, it is more prudent to retain it as distinct.

XYIiOTRECHVS Chevr.
X. planifrons. — Black, finely pubescent; the following parts clothed
with bright yellow hair; front except a narrow stripe; slender occipital band,
apical and basal margins of prothorax, scutellum, transverse sub-basal spot,
transverse band in front of the middle, extending along the suture nearly to
the scutellum; transverse band about one-third from the tip, and broad apical
margin; beneath with lateral yellow spots on each thoracic segment ; abdo-
men with broad bands of yellow hair; antennae and legs brown; frontal cari-
nas obsolete. Longte 7.5 — 13 mm.

California. Very similar in appearance to X. inslgnis Lee, but
smaller, with the sides of the prothorax moderately and regularly
rounded, not constricted behind; the subbasal spot of the elytra is
not oblique but placed transversely ; the prothorax and anterior part
of the elytra as usual is clothJed with long erect hairs. What especi-
ally distinguishes this speci«rs is that the usual frontal carinas are ob-
solete and represented by a scarcely perceptible and very small flat
callus. The front is elongated and flat as in other Xylotrechus, or I
should be disposed to refer the species to Clytus ; the maculation of
the elytra is not very unlike that observed in C. marginicollis. It
also agrees with that species and differs from the Xylotrechi, in hav-
ing the yellow hair confined to the scutellum and not extendin'"- to
the elytra.

TOXOTUS Serv.

T. Tirgatus.— Slender, black, finely densely sericeous pubescent, lateral
tubercles of prothorax large obtusely rounded, constrictions strongly marked ;
elytra with the pubescence transverse; testaceous, suture, discoidal stripe and
side margin blackish, tip obliquely subtruncate; abdomen of tne % ferrugin-
ous. Length 13 mm.

Oregon, Vancouver and British Columbia. This species might be
mistaken for a variety either of vittiger or vestitus, but on comparison
with the latter, which it resembles in the hairs of the elytra lying
transversely, the constrictions of the prothorax are deeper and the
lateral tubercle more prominent; in comparison with the former, the
head is less narrowed behind, the lateral tubercle of the prothorax is
larger and more obtuse, and the pubescence of the elytra is different,
the discoidal vitta is also narrower, confined to tne upper plane of the

68 J. L. LECONTE, M. D.

elytra and the lateral space between it and the margin is ferruginous.
The anteniuu in % are stout and as long as the body ; in the $ more
slender and a little more than half as long; the abdomen is ferrugin-
ous in the former, blackish with silvery pubescence in the latter, as in
T. vestitus.

STR.1XGAL,IA Serv.

S. 4leIioata. — Elongate, black; elytra testaceous, shining, sparsely punc-
tured, with the scutellar margin, and a short basal vitta blackish ; tips dehi-
scent, rounded; abdomen and legs ferruginous, tarsi dusky. Length 10 —
12 mm.

California. The prothorax is more sinuate on the sides, and the
hind angles less prolonged than in our other species ; the form is as
slender as in the male of any species and is scarcely less so in the 9
than in the % . The antennae have no sensitive spaces and the last
ventral segment of the % is not excavated but merely feebly im-
pressed and broadly emarginate at tip. The antennae are inserted on
a level with the front margin of the eyes as in all our other species.

liEPTlIRA Linn.

li. rhodopilS. — Elongate, black, tliinly and finel}' pubescent, thorax
densely not finely punctured, longer than wide, gradually narrowed in front,
feebly rounded on the sides, hind angles small acute; elytra parallel, coarsely
])unctureii, tif> subtruncate; feet bright ferruginous. Length fi.5 mm.

California. Allied to mbaryentata, rujibasis, etc., but the protho-
rax is less finely punctured.

OISERE.V Muls.

O. qiiailrieallosa. — Leiulen-black, clothed with fine cinereous pubes-
cence; prothorax yellow with four elevated black tubercles, the outer ones
being nearer the base, a little wider than long, sparsely but coarsely punc-
tured, disc elevated at the middle near the base; elytra coarsely punctured,
with two elevased lines, basal margin yellow extending a short distance along
the suture and side margin, tip rounded ; legs and abdomen yellow, 1st and 2d
ventral segments each with a broad blackish band, tips of tarsi black. Length
.65 inch ; 11 mm.

%. — With the last ventral segment broadly concave and emarginate; last
dorsal segment paojc«;ting beyond the pygidium, which is not retuse, but trun-
cate and subemarginate.

5. — With the last ventral channelled and less concave; pygidium retuse
and i)rominent just in front of the tip, closely applied to the last ventral.

Western part of California and Nevada. In one specimen three
ventral segments are dark, leaving onlv the -4th and 5th yellow. The
claws in this species are broadly appendiculate at base and the elytra
are rounded at the tip as in 0. Schaumii, to which it is closely allied.
It differs, however, by the prothorax wider, more rounded on the

AMERICAN COLEOPTERA. 69

sides, with the callosities more prominent and uot marked with a large
puncture as in that species; the 1st joint of the antennse is also a
little longer.

STEREOPAI.PUS Ferfe'.

S. priiinosns. — Dark lead-colored, clothed with fine cinereous pubes-
cence; prothorax carapanulate, very densely and finely punctulate, finely
channelled, less convex than usual; elytra more finely punctured than in the
other species; thighs frequently yellow, with the tips black. Length .28— .38
inch ; 7 — 9.5 mm.

California, abundant; Mr. Crotch. Of the same form as the
Eastern species, but with the prothorax less convex and the elytra
more finely punctcred.

EURT GENUS Ferte'.
Ell. eampannlatus.— Black, with a gray metallic lustre, clothed with
half erect i)ubesceuce; prothorax scarcely longer than wide, caiiipanulate,
deej)ly channelled, strongly constricted at tip, sides suddenly rounded before
the middle, then narrowed and nearly parallel, base margined, disc less con-
vex than usual, very densely punctulate, and with scattered large punctures;
elytra strongly and Ihickly punctured, marked with round spots of cinereous
pubescence; 2d joint of antenn« a little shorter than the 3d. Length .30 inch;
7.5 nun.

Vancouver ; Messrs. Matthews, four specimens. Differs from E.
cousfrictiis by more robust form and the absence of very long scattered
erect hairs, and from all other species by the prothorax being broader
and more suddenly rounded in front of the middle. The 2d joint of
the antennse is also comparatively longer, being but little shorter than
the 3d.

EUSTROPHIJS 111.
E. impressicollis. — Elongate oval, equally rounded at each end, not

very convex, brown, thinly clothed with very fine cinereous pubescence;
finely and very densely punctulate, prothorax wider than long, semicircularly
rounded in front, feebly bisinuate and finely margined at base, with a basal
impression each side, which is marked by a longitudinal line- antennae
scarcely reaching the base of the prothorax, joints 6 — 10 gradually but slightly
wider. Length 6.5 mm.

Vancouver Istand. This species has a perfectly regular elongate
elliptical form and is less convex than any other known to me. It is
also easily distinguished by the longer basal impressions of the pro-
thorax and by the last joint of the maxillary palpi being broader, and
more obliquely truncate; the spurs of the hind tibiae are compara-
tively a little smaller and the elytra are not striate.

BL.APSTINUS Latr.

B. Inf ifroiiN. — Oval, rather elongate, moderately convex, di-ll black,
densely fmnctured, finely pubescent; front wider before the eyes and distinct-
ly angulated at the sides; prothorax a little wider than the elytra, twice as
wide as long, narrower in front, much rounded on the sides, base sinuate to-
wards the sides and broadly truncate at the middle; hind angles obtuse, well
defined ; disc broadly convex, sides widely depressed. Elytra a little narrow-
er than prothorax, elongate, sides parallel, tip rounded, striae fine, finely punc-
tured, not deeply impressed, interspaces nearly flat. L. 9.7 mm.; .38 inch.

One specimen, Vancouver Island; Mr. Crotch. Near B sordidtis,
but larger, narrower and distinct by the clypeus being angulated at
the sides, the prothorax narrowed towards the base, and more strongly
rounded on the sides, and by the interspaces of the elytra not alterna-
tely more convex.

ASC'LERA Schmidt.
A. discolor. — Black, finely pubescent; mouth, prothorax and elytra dirty
yellow; prothorax very finely punctulate, narrowed and constricted behind,
disc with two very large excavations and a smaller one near the base; elytra
densely ami finely punctureb, with Ihe usual 3 elevated lines, the inner one
less distinct; dusky towards the tip; legs dusky, tip of thighs and base of
tibise yellow. Length .2" inch; 7 mm.

(■aliCornia; Mr. Crotch, eight specimens. This species precisely
resembles ^4. excavata and ni[/ra JiCC, diiFering only in color.

RHI^'A Kirby.
R. fronfnlis. — Black, shining; bead sparsely coarsely punctured, beak

straight, as long as the prothorax, coarsely and comewhat densely punctured,
obsoletely s>ulcate and 3f)arsely setose each side; frontal fovea distinct; eyes
nearly contiguous beneath, but widely separated above; prothorax a little
longer than wide, narrowed in front, and broadly rounded at the siiles, apex
tubularly constricted, disc coarsely but not densely punctured, base nearly
straight, margined ; elytra cylindrical with rounded humeri, sides parallel,
apex rounded, strife finely punctured, interspaces flat, with a few distant
small punctures; prothorax with the flanks and under surface densely and
coarsely punctured, trunk and abdomen sparsely punctured, front tibire with
5 — t") small teeth on the inner edge. Length .32 — .45 inch ; 8 — II mm.

Mojave Desert, under bark of Vucca j Mr. Crotch. This species
differs from the others by the eyes not extending on the upper sur-
face of the head, so that the front is broad and convex. The appear-
ance is that of a gigantic Cossonide. The pygidium is almost covered
by the elytra, but projects a little as in R. barbirostris.

Further study may require this to be separated as a distinct genus.

CRYPIIAL,US Er. (emend.)

C. cariimlatus.— Cylindrical, less elongate than usual, black or brown,
thinly clothe*! with long erect hairs; prothorax one-third longer than wide,
sides parallel, apex rounded, hiud angles obtuse and rounded, disc rough in

front, as usual with transverse rows of sharp granules, punctured behind, with
a nearly smooth space each side; dorsal line smooth, narrow and slightly ele-
vated ; "behind the roughened part is a broad shallow transverse impression;
elytra with approximate rows of rather distant punctures, posterior declivity
deeply sulcate next the suture, outer edge of declivity with three small denti-
cles, between which and the suture are two larger and more prominent acute
teeth; front tibiae with 4 — 6 distant acute teeth. Length .08— .12 inch;

2 — o mm.

Lake Tahoe, Calaveras and Mojave region, California ; Mr. Crotch :
Vancouver Island; Mr. Matthews. This species is allied to C. niti-
dulm, but is larger and less elongate. It is easily distinguished
by the dorsal line of the prothorax being feebly elevated, and there-
fore subcarinate, while in nitidalus and atratitlux the line is broader
and flat. The teeth of the posterior declivity of the elytra are more
developed and placed in the same manner as in certain species of
Xi/lohoruii, but the club of the antennae is not at all as in that genus;
the transverse sutures are quite distinct and convex forwards, pre-
cisely as in C. nitvhdus. In the black specimens the shank of the
antennae and the tarsi are brown.
/ C. puncUcolliS.— Cylindrical, black or brown; prothorax nearly one-
half longer than wide, in front with transverse rows of acute granules, behind
sparsely and strongly punctured; elytra with rows of rather close set punc-
tures, rows not approximate; posterior declivity deeply and broadly sulcate,
outer edge of declivity obtuse; denticles very small, scarcely perceptible.
Length .05— .06 inch; 1.2— 1.5 mm.

Calaveras, California; one specimen, Mr. Crotch; Texas; Mr. Bel-
fraf^e. Also allied to 6'. nltldalns, but much smaller, with the elytra!
rows of punctures finer and more distant, and the denticles of the pos-
terior declivity small and inconspicuous.

V C. digestus.— Black, shining, thinly clothed with fine erect hair; protho-
rax one-third longer than wide, rounded in front, rough with acute tubercles
and sparsely pubescent, disc behind strongly not densely punctured, with
smooth median spaces, and a vague transverse impression behind the rough
portion; elytra with somewhat irregular rows of moderate sized punctures, su-
tural grooves extending from the middle to the tip, posterior declivity convex,
nearly smooth, with the suture elevated, and the furrow composed only of the
sutural stria. Length .70 inch ; 1.7 mm.

Mojave Desert; Mr. Crotch. Allied to (J. jmberulus Lee, hat
with the punctures of the elytra more distinctly arranged in rows ;
and the pubescence finer. Rubbed specimens may appear to resem-
ble atratulus and nitidalus, bnt the elytral punctures are much smaller,
the rows more approximate, and the groove of the posterior declivity
much narrower.

XYL.I-:ilOKlIK Eichhoff.

X. viciims. — Cylindrical, i)l!iek or brown, antennre and feet dark ferru-
ginous,; prothorax longer tiian wide, broadly rounded on the sides, gradually
narrowed in front and roumled at tip, puncture<l behind, granulate and hairy
in front; elytra with distinct rows of punctures, interspaces flat with single
rows of more distant punctures, sparsely clothed with long erect hair; pos-
terior declivity concave, edge of concavity with several small denticles and
two large ones. Length .10 inch ; 2.5 mm.

Hritisli Columbia; Mr. Crotch. Allied to X. caelatus Eichh., but
the elytral punctures are smaller and more distant, and the inter-
spaces wider and flat. The denticles of the posterior declivity are
similarly arranujed and the two lar<rest are rather within than upon
the margin of the declivity. The tibiie are coarsely and irregularly
serrate as in ciu/ikuk.

X. lianiatus. — Black, rallior robust, with a few erect hairs ; prothorax
scarcely longer than wide, nearly square, with the apex rounded as usual, disc
punctured behind, with a narrow smooth dorsal space, punctures before the
middle rougiily and acutely granulate; elytra with rows of distant punctures,
sutural groove deep, broader behind, and expanded into the very deep pos-
terior excavation, which is smooth and sharply margined ; near the upper
part of the declivity on each side is a long spine bent downwards at the end.
and near the tip is a small acute tooth. Length .12 — .16 inch ; 3 — 4 mm.

Mojave Desert, California; Mr. Crotch. J observe no sexual dif-
ferences in the individuals before me. This species resembles X. pla-
giatna Lee, S in the singular armature of the elytra, but is much
larger and otherwise (|uite different.

Several species of Xyleborus are in Mr. Crotch's collection, but
are too closely allied to those already described to be properly
mentioned on the present occasion.

T09IICVS Latr.
T. latitlens. — Cylindrical, brown, shining, clothed with long erect yellow
hairs, prothorax more parallel on the sides than usual, not much longer than
wide, more broadly rounded in front, hind angles rounded; disc sculptured as
in T.pini,\noT& strongly impressed each side near the middle; elytral strise
deep, closely punctured, interspaces each with a row of punctures; posterior
declivity concave as usual, subsutural denticle small acute, next tooth broad,
composed of the confluence of three cusps, of which the upper one is least de-
veloped and the middle one most prominent; following this is a long acute
tooth, and then the usual apical acute margin. Length .12 inch, 3 mm.

California; Mr. Crotch. Smaller than T. pini, with a shorter pro-
thorax and very different elytral sculpture and armature.

Descrptioiis of New Species of COIiEOPTERA from the
Pacifie Coast of the United States.

BY Q. R. CROTCH, M. A. CANTAB.

[The descriptions here published were the last prepared by Mr.
Crotch, and were intended to make a companion paper to those by
Dr. Horn and myself. Many species which he desired to describe,
belonging to families to which he had given special attention, re-
main undetermined, the rapid progress of the pulmonary phthisis
which caused his death, having rendered all scientific labor impossible.
I have, by the kind permission of Mr. W. D. Crotch, retained a series
of the unnamed forms, which will be investigated fully at a future
time. — Leg.]

Oimis sequoiaruni, n. sp.— Closely allied to 0. californicus, but rather
longer and markedly broader and stouter; the labrum is produced in front,
instead of being transverse or at most convex; the antenna are clearly thicker
and shorter; the thorax is broader and shorter and less constricted at the base,
the sides are more rounded, the disc is much less wrinkled, without being as
smooth as iu O.Audouini; the elytra are also broader and more convex. L.
17.5 mm.

Very distinct by the form of the thorax, which is so broad that the
side pieces are not visible from above, as is the case in the other
species. Found at present only at Calaveras in the Sierra Nevada,
originally by Mr. Edwards, and afterwards by myself, in June, 1873.'
I have seen in all 20 specimens precisely similar.

O. E:lwar€lsii, n. sp.— Again allied to 0. californicus, but longer, and a
generally larger insect; the antennae are much stouter (being in fact thicker
than in any other species), the labrum is convex in front, head broad, super-
ciliary ridge obsolete; thorax as broad in front as it is long, sides straight, ob-
lique, much narrowed towards the base, disc feebly wrinkled as in O.'sequoia-
rum; elytra with the sides yiore parallel and less ventricose. L. 17.5^18 mm.
This is a larger and stronger insect than the' others, with thick an-
tennse, heavy femora and longer tarsi. All the known specimens (6
in number) come from Lake Tahoe where it was first found by Mr.
Henry Edwards, and again by myself I have great pleasure in dedi-
cating this species to its original captor, who had already detected the
distinctness both of this and the preceding species.

Hydroporus (Coclambus) ungnicniaris, n. sp.— Elongate ovate,
fulvous, breast and abdomen black; head finely punctulate with smooth spaces;
thorax transverse, sides slightly rounded, punctulate, disc nearly smooth, with
a small black central mark and a linear fovea, base and apex faintly black;
elytra regularly elongate-ovate, closely and finely punctate throughout, each

with the suture (very narrowly) and three lines black, almost entire, a fourth
line is broadly interrupted in the middle and at the apex. % anterior tarsi
short, broad, 3d joint deeply bilobed, external claw thickened, internal re-
duced to half the ordinary size, so as to appear rudimentary. L. .5.5 mm.

British Columbia, one male. Resembles R. paralleloijrammus of
EurDpe.

Ilydroporut* (Cocliiinbiis) inascpilinus, n. sp.— Somewhat obovate,
pointed behind, pale fulvous, breast and abdomen black; head very finely
punctulate; thorax short, transverse, sides straight, base margined with black,
finely and rather closely punctulate; elytra thickly and finely punctulate,
pale yellowish, with the suture and four narrow lines black (the first and third
not quite reaching the base). % anterior claws much elongate, deformed, sub-
equal, the external one flattened. L. 4.75 mm.

Lake Jjabache; very distinct by tlie male characters: the 3d
joint of tlie anterior tarsi is also feebly bilobjd and the claw joint is
large and hardly longer than broad.

Il.y<liiol>iiis Mattliewisii, n. sp. — Eather elongate, parallel, convex,
testaceous; antennae rather short, stout, 7th joint nearly as long as 9th, club
pale head finely punctulate; thorax broader than long, narrowed towards the
front which is truncate, front angles rounded, sides rounded towards the base,
hind angles evident, obtuse, surface rather thickly punctulate, with a trans-
verse punctate basal impression terminating in a fovea on either side; scutel-
luia strongly punctate; elytra punctate-striate, sutural stria more deeply im-
pressed, intervals punctulate and confusedly rugulose; body beneath smooth,
femora deeply punctate. L. 4 — 6i mm.

Flying at dusk near Gold Stream, Vancouver Island. The Messrs.
Matthews took three or four fine male specimens of this species, which
deepens in color to piceous-brown, and the punctuation varies in
intensity.

AniNotoniH paliidioola, n. sp. — Regularly ovate, dark chestnut-brown,
antennre hmg, club hix, head scarcely' punctulate ; thorax convex, posterior
angles obtusely rounded, surface shining, clearly ajid rather closely punctate;
elytra also rather closely punctulate throughout, and feebly transversely rugu-
lose, a sutural row of punctures tolerably marked. L. 34 mm.

Sweeping at dusk in the mirshes on El Cajon Ranch, near San
Diego. Allied to A. morulus, but distinct by the more strongly punc-
tate thorax and the irregularly punctate elytra.

Prostomis amcricanus, n. sp.— Elongate, flat, testaceous-red, paral-
lel ; head and thorax rather obsoletely punctate, the latter longer than broad,
with a median line; elytra punctate-striate, intervals smooth. L 5J mm.

Flying at dusk near Gold Stream, A'"ancouver Island, at the end of
July. It is extremely close to the European P. mandibular U^ from
which it only differs by the longer 3d joint and the more oval terminal .

joiat of the antennge, the more rounded sides to the thorax and the
shape of the jugular processes, which are very much less curved in-
wards towards each other in the American species.

I^ii^conotHS? linearis, n. sp. — Elongate linear, not very convex,
pitchy brown, clothed with a tolerably dense golden pubescence ; head broad,
scabrous; thorax longer than broad, front angles acute, sides crenulate,

fovesE towards the base, which is strongly margined : elytra each with five
slightly raised lines, intervals with two rows of rather deep punctures, base
and subapical spot rufous; body beneath opaque, punctate. L. 2.7 mm.

Under bark of Sycamore or some small forest tree at the Hot
Springs in the Sta Inez Mountains. The little genus Ozojnathu^/Wd'i
excessively cojimon in the same bark. This species agrees with Las-
coiiotus in the 3-jointed club, but has the sculpture and appearance
of Si/nchi/todcii\_Ditoma']; it should probably form a separate genus,
which may be compared with lllestus Pascoe.

Oxylsemus caliTornicus, n. sp.— Elongate, cylindrical, dark red,
finely pubescent; head punctate; thorax elongate, very coarsely punctate,
with a smooth medial line and well marked basal impression near the hind
angles; elytra punctate-striate, interstices smooth; prosternal epipleuree ru^u-
lose, ventral segments coarsely punctate. L. 3.5 mm.

Calaveras, Sierra Nevada.

Tl'OgOi^ita yuccae, n. sp.— Elongate, dark pitchy brown, legs paler; head
finely subrugulose, sparingly punctate, a short impressed frontal medial line,
anterior edge deeply tridentate; thorax about as long as broad in front, sides
almost straight at first, then rapidly obliquely narrowed towards the base,
sides and base strongly margined, hind angles very obtuse, sculpture as on
head; scutellum transverse, very small, elytra margined at base, with rows of
impressed punctures, intervals flat, also with rows of finer punctures, at the
apex a small sutural stria is indicated; beneath brownish, prosternum with a
few deeply impressed punctures. % mentum with a fulvous tuft of hairs. L.
19 mm.

Under bark of the tree Yuccas on the Mojave desert in May.
Apart from the color it may be noticed that the eyes are more strongly
granulated than in T. vh-escens.

Differs from T. harhata by much more sparse punctuation of head
and thorax and very weak punctures on the elytra,

ColasttiS yuccse, n. sp.— Broad, depressed, opaque, black, pubescent,
closely subrugulosely punctate throughout; thorax broader than long, feebly
emarginate in front, front angles rounded, sides and base margined, the former
broadly rounded, as are also the hind angles, base feebly sinuate in front of
the scutellum ; elytra with the sides acutely margined ; pygidium sculptured
as the rest of the upper surface. L. 5 mm.

Abundant in the unopened flower heads of Yucca in the ^lojave
desert.

Colastiis agavcn»!iis, n. sp.— Subdcpressed, shining, with a faint golden
pubescence, color varying from brown to fulvous, head punctulate. with a
transverse line between the antennfe; thorax transverse, not emarginate in
front, angles deflexed, rounded, sides and base margined, the former rounded
as are also the hind angles, disc dark brown clearly punctulate ; scutellum

shining, pubescence yellow; antennfB with the cl ib yellow, last joint narrower
than 10th; thorax broader than long, narrowed.in front, greatest breadth be-
hind the middle, sides rounded, posterior angles slightly produced, acute, sides
explauate, margin reflexed, not thickly punctulate; scutellum punctate;
elytra broader than thorax, sides rounded, explanate, punctuation subrugulose,
apex obliquely punctate. % intermediate tibiae simple. L. 4 — 4.5 mm.

Canada; (Horn.) This is the largest and broadest Eparaea known
to me.

E. (Dadopora) toxaiia, n. sp.— Suboblong, not convex, entirely of a
rich fulvous ami clothed with golden hairs; antennie with the 11th joint
smaller than the 10th; thorax slightly transverse, very little emarginate in
front, sides only slightly rounded, margins reflexed, but not explanate, hind
angles right angles, sparsely punctate; elytra rather sparsely punctate, trun-
cate behind, angles rounded ; beneath 6nely punctate. 9 intermediate tibiae
simple, posterior dilated, constricted at the base. L. 2.5 mm.

Texas; (Leconte.) This belongs to the same section as the E. 10-
guttata, of Europe. E. helvola Er., is very distinct by the distant
posterior coxae and should form a new subgenus, which may be called
Epurpcanella.

E. ? inoiio«;Hina. n. sp. — Deep brown, margin and legs rufous, somewhat
shining, parallel, subconvex; upper surface closely and visibly punctate,
punctures subrugulose in some lights, or possibly very faintly pubescent;
thorax deeply etnarginate in front, sides broadly margined, hind angles largely
explanate, prominent, subacute, base not margined, sinuate behind the angles ;
scutellum triangular, punctate; elytra with the sides broadly flattened, ai)ex
subtruncate; beneath closely punctate, thoracic epipleurse rugose. % with an
additional dorsal segment. L. 5 mm.

Found in Vaucouver and throughout the Sierra Nevada in the
small white globular fungus which occurs on dead pines. This will
be found to have a hole underneath, and if carefully detached a pair

of the above insects will gennerally be found, unless a marauding Tro-
gosita has taken possession.

PTOMAPIIAGIJS III.

P. leptiuoides. n. sp. — Broad, depressed, shining, rather pointed behind,
bright fulvous sparsely pubescent ; head and thorax sparingly punctate, shi-
ning; elytra subrugulosely punctate, epipleurse scabrous; ventral segments
finely punctate; antennae with the joints elongate, 2 = 3, 8 smallest of all and
narrower than 7 or 9. ^ anterior tarsi with three joints dilated. L. 3 mm.
Fort Crook ; (Horn).

This remarkable species has a strong external resemblance to Lep-
tinus, the head being small so that the thorax is largely rounded on
the sides, the posterior angles are produced but rounded.

GRYNOCHARIS Thorns.

G. pilosnla, n. sp. — Brown, oblong, su boon vex, thickly clothed with a
sericeous pale decumbent pubescence, mixed with sparse erect hairs arranged in
rows; thorax transverse, sides rounded, erenulate, broadly explanate, front
angles rounded, shining, sparsely punctulate; elytra shining, rather less
strongly pubescent, deeply and pretty closely punctate, sides explanate in the
basal third; beneath pubescent, body dark. L. 4.5 — 5 mm.

Note on the genus PL.EOCOIMEA Lee.
BY JOHN L. LECONTE, M. D.

Some years ago I received from my excellent and liberal friend,
Mr. Andrew Murray, of Loudon, a female of this singular genus. I
was unwilling at the time to describe it, as both antennae were gone,
and the specimen otherwise much mutilated. I saw a similar one in
the collection of Dr. Candeze, at Liege, and recently Mr. Behrens, of
San Francisco, has loaned me a more perfect individual, belonging to
a different species.

The genus was founded by me * upon a mutilated specimen, which,
however, retained enough of the antennae to show that they were 11-
jointed, with the 6th joint wider than preceding, the 7th still wider,
and the 8 — 11 forming an elongate lamellate club.

Just before leaving the country, in 1857, on a long journey, I re-
ceived perfect specimens of what seemed, on hasty examination, to be
the same species, and I had barely time to pen a note to be appended
to the Pacific K. R. Report, which was printed during my absence ;
calling attention, however, to the important difference in the antennae,
which in these new specimens, had the 4th joint prolonged inwards,
joints 5 — 11 forming a 7-leaved club, f I also indicated the differen-
ces in the prothorax, finely and sparsely punctured in the 4-leaved
specimen, quite densely punctured in the two with seven leaves.

No other specimens in the mean while occurred, and I was still un-
willing in my classification of Coleoptera.| to indicate these two forms
as distinct species. The condition of the type such as to render its
study very unsatisfactory, and the observations were therefore made
upon the perfect individuals of the second species.

In 1870, Dr. M. Schaufuss, (Nunquam otiosus, vol. ii.) after reci-
ting the same history 1 have given above, describes at length a form
with 7-leaved antennal club. The name under which he makes it
known is inadmissible, and it must therefore be regarded as unpub-

lished. In the same paper he describes another species P. hirticolh's,
in which the antennae are 8-lcaved, but the 4th joint, which is only
slightly prolonfi;ed is counted in the club. This species seems to be
the second form mentioned by me, of which I figured the antenna.

The females are much larger than the % , very ovate and convex,
without wings, with the legs stouter and the tarsi short, only one-
third as long as the tibiae. The prolongation at the front of the head
is short and broad, not emarginate, the vertical horn short, the pro-
thorax coarsely punctured, not impressed, and finally the antenna?
very much smaller, with the club rounded.

Just as this paper was being put to press, T received from Mr. Beh-
rens a larva found deep in the earth. The description of it, by Baron
Osten Sacken, will follow this note. I will merely observe, that its
characters fully confirm the propriety of placing the genus as a dis-
tinct tribe, near Irox and Geotrupes, as I have done in my Classifica-
tion.

The four species known to me may be divided into two groups ac-
cording to the form of the antennae, and the diiferences expressed in
in the following table : —

I. AntenusB with joints 3 — 5 nearly equal, not dilated.

6th joint scarcely wider than the 5th; 7th prolonged into a short leaf, one-
fourth as long as the 8—11 1. fiinbriata.

6th prolonged inwards forming a leaf one-half as long as the 7th, which is
shorter than the 8— II 2. Behrensii.

II. Antennae with 3d joint elongated, 4th acutely produced inwards, 5th lamel-

liform, though shorter than the following ones.
Hind angles of prothorax feebly rounded, disc clothed with long hair, elytra

feebly striate 3. ItirticolIiM.

Hind angles of prothorax strongly rounded, disc strongly retuse, elytra

deeply striate 4. Edwardsii.

E. OSTEN SACKEN.

This species is recognizably described, though not properly named by
Mr. Schauf'uss (Numquam otiosus, vol. ii.). 'I'he name suggested for it
by Mr. Crotch (Check List, p. 58), is likewise inadmissible, not only be-
cause he gives no reason for its adoption, and because that kind of list
is an improper place for changes in nomenclature, but for the still
stronger reason, that it tends to perpetuate in science the memory of
the political venom which inspired the name given by Mr. Schaufuss.
I cannot express myself too strongly on the necessity of keeping our
scientific nomenclature free from all personal, political or religious
prejudices or expressions of opinion. Such use of scientific pubttca-
tiou, for intruding upon students of natural history irrelevant views re-
specting subjects, which are not comprised within the domain of their
researches, must be discountenanced.

Description of the larva of PL.EOCOMA, Lee.
BY BAllON R. OSTEN SACKEN.

The larva, sent for examination, is fresh from a recent moult. Some
parts of the head, especially the parts of the mouth, are still covered by
the old skin ; exuviae of the tracheal tubes protrude on both sides from
the thoracic stigmata. I mention this in advance, in order to introduce
a remarkable circumstance to be mentioned below.

Larva (fig. 1) of the usual lamellicornian type, fixt, soft, whitish
curved, about 50 millim. long.

Head (fig. 2) rounded, yellowish-red, with the usual inverted Y-
shaped impression in the middle ; the occiput is longitudinally wrinkled ;
the front, preceding the epistoma, shows iiTCgular transverse wrinkles;
the space between front and vertex, especially on the sides of the head.

AMERICAN COLEOPTERA. 85

is smooth and shining. The space transversely wrinkled bears some
few bristles, more numerous on the sides. On the upper portion of
the head I perceive six bristles, three disposed in a triangle, on each
side of the i^^-shaped line.

Epistoma trapezoidal; lahrum semicircular, its upper coriaceous
covering trisinuated anteriorly, with two small projecting lobes be-
tween the lateral sinuses; the lower, fleshy part is armed, as usual
with minute, stout, erect bristles. Epistoma and labrum reddish-
brown.

Antennx three-jointed (not counting the scapus), but little advanc-
ing beyond the tip of the mandible; first joint subcylindrical, long;
the second cylindrical, about f of the length of the first; tiie third
very small, about } of the length of the second and much more
narrow.

Mandibles horny, very strong, dark brown or black, more reddish
towards the basis, projecting but little beyond the labrnm. When I
first examined the larva, I found both mandibles looking alike, tri-
angular, slightly curved towards the inside at tip, with a small tooth
on the inside of the broad basis. I soon perceived however that the
mandibles had not yet thrown off their old covering during the moult,
and I easily removed from the left mandible, a horny shell, which after
removal, preserved its former appearance. The mandible disclosed
under it shows an altogether different structure, (compare fig. 3. a).
It consists of a stout, reddish-brown horny basal piece, with a black,
double tooth on the inside; on this basal part a black, horny, almost
cuitriform piece is inserted, slightly convex and longitudinally furrowed
on the outside (the tip being smooth); concave and likewise with
numerous longitudinal furrows inside. Between these two pieces the
mandible shows an excision, in the shape of an angle of about 45°. of
which there was no trace in the same mandible before moulting. The
right mandible is probably of the same structure, but I did not re-
move its old skin; an opening in it however allows a partial view of
the new mandible within.

MaxiUse, (fig. 3) with two lobes; the outer and upper one small,
cylindrical, with a few short spines and with a small conical, homy,
piece at the tip, attached by an articulation ; the inner and lower lobe
is a little larger and beset with numerous spinelike bristles, and ha^,
at the tip, a similar horny, but more unguiform, piece. Maxillnrij pnlpi
apparently 3-jointed (besides a small ba.sal piece), projecting but little
above the maxillae; joints about equal in length.

86 R. 08TEN SACKEN.

The palplgerous piece of the labium (fig. 3) is a fleshy tubercle,
beset with bristles ; the mentum under it is not an independent piece,
and merely marked off by folds around it. The palpi are horny cones,
inserted upon scutiforni basal pieces ; their tip does not project much
above the fleshy labium upon which they are inserted.

The thoracic segments are more glabrous than the others, being beset
on the upper side with transverse rows of sparse, soft hairs ; the third
segment, besides its row of hairs, has a row of minute spines. The
breast and pleurae also have some long, and rather soft hairs. The
first segment shows, above the spiraele, on each side, a pale yellow
region of indefinite outline, ending anteriorly in a reddish yellow spot;
this evidently is a rudiment of the horny plate which exists here in
other lamellicorn lai-vae.

The fvet (fig. 4) are somewhat shorter than the rather large coxae,
they are beset with spine-like bristles, and end in a pencil of such
bristles, almost hiding the small unguis between them. The front
pair of feet is perceptibly smaller than the other two and has only
small coxae. All the feet are far apart at their bases.

The abdomen, above, is densely beset with minute spines, rather
evenly distributed over seven dorsal segments and not quite reaching
the stigmata on both sides; the eighth segment is almost free from
them ; the ninth or last segment is beset with them on its posterior
part only, round the anul opening. A row of soft hairs runs acros?
each segment, from stigma to stigma. The venter has similar rows of
hairs, becoming very sparse on the last segments.

The thoracic, as well as the abdominal segments, are divided by
deep furrows in transverse bolsters, the longest of which bears the
stigmata at its ends. The last abdominal segment is as long or a little
longer than the two preceding taken together and is divided in two
halves by a transverse furrow. The anal opening is j^-shaped. The
arrangement of the stigmata is the normal one.

When I compare this larva with the analytical table of the lamelli-
corn larvae by Erichson, reproduced by Chapuis (Larves des col., p.
454), I find that it has the two separate maxillary lobes attributed to
the Scarabaeidae Laparosticti ; it has the segments divided by deep
furrows into transverse bolsters, like the subdivision A in tliut table
{Geotrupiilx, Aiiliodiidse, C'upridcP., Troijidse). When I further com-
pare our larva with the few existing descriptions of larvae of these
groups, T soon perceive that the choice will lie between the G'cofriipi<fpe
and Tioijidx. The Aphodiidx and CopridsearQ excluded by the struc-

AMERICAN COLEOPTERA. 87

ture of their antennae, maxillae, labium, etc. Of those two groups we
possess, as far as I am aware, only two good descrptions of larvae :
Mulsant's of the larva of Geolrupes sfercorarius and Chapuis' of the
larva of Trox carolinus. If we were to base our opinion upon these
two descriptions only, it would incline in favor of a relationship of our
larva with the Trogirlse,, rather than with the Geotrupidse. Chapuis'
description of the larva of Trox carolinus agrees quite well with our
larva; the description of <he labium especially (levre inferieure forniee
d'un menton et d'une piece palpigere fondus en un real corps allonge)
seems to indicate a structure somewhat analogous to that in our larva.
On the contrary, Mulsant's description of the larva of Geotrupes dis-
agrees with ours in several points. The antennae are said to be four-
jointed, the maxillae to have two almost cylindrical lobes, the legs are
described as bilobed at the end, etc. Finally, if it be true that the
larva of G-eotrupes has only two pairs of well developed legs, the third
being almost atrophied, as Frisch (but not Mulsant) describes it, this
would constitute another important difference.

Altogether, the materials at hand for comparison are too meagre for
a final decision upon the relationship of the larva.

Before concluding I would advert once more to the singular fact
that the shape of the mandibles changes after moulting. A similar
peculiarity has been already observed among larvae of other orders of
insects. That the shape of the earlier mandibles is merely due to its
being more worn is a supposition which will hardly be entertained by
any one who has compared the two mandibles-

er at the base, the 1st as long as but stouter than the l:}d. The eyes are
much smaller, though nearly smooth; the under surface of the head
is quite different; gular sutures distant, curved slightly outwards,
gular angles not porrected, but broad and truncate ; mentum more
prominent, maxillae more exposed, maxillary palpi longer, last joint
elongate, cylindrical, truncate. These differences were jiartly indi-
cated by me in the remarks appended to the description of the species.
The color is mottled gray ; head with four subacute tubercles, but not
lobcd, front concave. Prothorax nearly square, with front angles
prominent; elytra more convex, alternate interspaces feebly convex
and a little uneven; side margins strongly toothed towards the tip.

divided into two large posterior tubercles or lobes, and two smaller frontal
ones ; there is also a lateral lobe behind the eye, separated by a deep groove,
eyes large; prothorax suddenly narrowed in front, with the sides strongly
elongated and a large median elevation which has a deep rhomboidal excava-
tion ; elytra with rows of moderate sized quadrate punctures, :id interspace
more convex, 5th, 6th and 7th forming an obtuse costa, 2d and 4th Hat. Length

Remarks on Korth American IVOCTUIDAE
with descriptions of l^ew Species.

BY AUGUSTUS R. GROTE.

AGROTIS, Htibner.
Agrotis Normanianns, Grote.

S 9 . — This seems the species that is intended under the name oftri-
nngulum in tne " List of the Noctuidae of North America." I have
recently compared a fine series, taken by Mr. George Norman, with a
number of European specimens of friavgulum, part of which I owe to
the kindness of my esteemed friend Professor P. C. Zeller. I have no
question that our American species is distinct and Mr. Norman, who
is of the opinion, thinks that there is a certain resemblance in our in-
sect to the European (■{■) depuncta. The general appearance and
style of markings of the two species, triangulum and Normanianuf,
is very similar. On a comparison of the male antennae, they seem
more heavily bristled in the American species. The subterminal
space anteriorly and the terminal space are darker shaded and con-
trast in Norma iiianus. There is a less general evenness of color on
the primaries in our species, which wants the dark brown shade suc-
ceeding the basal half line on the sub-basal space. The ground color
is more ashen, shaded and tinted with rose-brown. The geminate
lines are narrower, the component lines equally marked. The t. p.
line is less prominently lunulated inwardly. The orbicular is less tri-
angulate, being more obliquely quadrate, owing to an angle being formed
opposite to the reniform, this latter shorter and narrower than in the
European form. The pre-apical black shade spot on the costal region
before the subterminal line is single in Normanianus. The hind wings
and undersurftice are similar in the two species, but Normanianus is
better marked and has the common line notably sinuate inferiorly ou
the hind wings; it is the smaller species, expanding 35-36 m.m.
Worn specimens are of a dingy ocherous or olivaceous ashen, having
lost the rosy tintings.

Canada, Eastern and Middle States. Imago in July and August.

Agrotis triangulum is cited in my list as American ou the authority
of Mr. Walker. This author has made several analogous determina-
tions which will have to be probably corrected when we become ac-
quainted with the European species. In the genus Agrotis we have
determined American species under the names Agrotis C-nigrum, plecta ,
haja, fennica, con/lua, saucia, and s^ffusa, after a comparison with
European specimens, and in these instances we can find no difi'erences

to authorize any separation. With regard to augur, no comparison has
been made, and our species may be different. No actual comparison
has been made by us of segi'tum and texauus, but, after receivinjj;- speci-
mens of the former, our species is believed to be identical. The Cali-
fornian species identified as hjcarum may not be the same, and indeed
it is only with diflSculty to be separated from Cochranli A species
has also been lately taken by Mr. George Norman, in Canada, wiiich
appears to be the same as the European A. rubi (rubella Tr.).

Mr. George Norman has kindly communicated to me his dates of
capture of the species of Agrotis at St. Catherines, Canada, and I sub-
join his statements.

KiiroiN preNMiis, Grote. — 5 9 • — A. slender bodied species of small size for

this genus, resembling Schccnhervi, H.-S. fig. 598, distinguished from the smaller

forms described under Aplecta by Giiende, and which I have referred to Mames-

tra, by the naked eyes. The middle and hind tibiae are spinose. The antenna;

simple, scaled above, and setose beneath, not brushlike in the male. The color

is a dusky gray and the species shows an affinity with E. hcrbida by the prima-
ries being more or less distinctly shaded with green, principally from the base

outwardly over the reniform, and along the submedian interspace. Orbicular

large, round, a little oblique, black ringed, with pale center and an internal
annulus; the disoal space around the spot and before the reniform is more or
less noticeably filled in with black. Eeniform also pale, with fainter internal
ringlet, black ringed, well sized. The transverse lines are obsoletely geminate,
filled in with white, and this filling in rather strikes the eye and seems to be
characteristic. The claviform is large, its upper black edge appears as a black
arcuate Hue below the median vein, its lower edge ''s indistinct. The subter-
minal line is more or less obviously preceded by black shade dashes, usually
determinate in pairs on submedian fold, between veins 4 and 6 and again sub-
costally; a dentate black terminal line defines the uneven margin of the wing;
frino-es gray. Hind wings very pale, shaded with fuscous terminally, with an
irregular faint median fuscous line and black terminal linear edging; fringes
whitish. Beneath very pale,subirrorate and shaded with fuscous, with a com-
mon line and discal marks. Palpi with the terminal joint white, the second
black on the sides. Head whitish; thorax mixed with black. Abdomen weak,
untufted. Expanse 3fi mm.

Hadena niactata, Ajyamea macte<a Guen.Noct. l,p. 207. Hadena mactata
Grote, List of the Noct. N. A. p. 15. 5 9 .—This species, with naked eyes, has
much resemblance to Mamestra claviplena Grote, in size and color, though this
is generally paler. Woodbrown; the median space darker shaded. A black
dash at base, and one below it on internal margin. The geminate black
lunulated median lines come nearly together on the internal margin. The t. a.
line runs outwardly strongly obliquely. The t. p. line is roundedly exserted
beyond the cell. Ordinary spots large, concolorous, pale ; orbicular obliquely
oval with a center stain; reniform with interior annulus. Claviform dark,
concolorous, finely outlined in black, wide, not long, resting on a black dash
which connects the t. a. and t. p. lines along the submedian fold. Subterminal
space pale and the dentate s. t. line distinct, again paler, very near the margin.
The woodbrown fringes are cut with pale, at the extremity of the veins. Hind
wings dark fuscous with indistinct darker median line; fringes pale. Beneath
pale, somewhat testaceous, irrorate and shaded with fuscsus, with a common
uneven line and small pupilled discal marks on both wings. Head and thorax
mixed pale and woodbrown. Expanse 28 mm.

No. 193, St Catharines, Mr. Geo. Norman. The discal marks
beneath take the shape of small lunulas with a more or less distinct
pale center. Although Guenee's description is not very complete, it
seems to me sufficient.

Hadena flava, Grote. 5 $. This is a rather small species with clear
bright yellow hind wings and broad black borders which reminds us at first
sight of Anarta cordigera. The structural characters are those of Hadena. The
eyes are naked. The squamation of the thorax is hairy. The dorsum of the
thorax has an anterior and posterior divided tuft. All the tibiae are unarmed.
The dorsum of the abdomen shows determinate tufts. Fore wings blackish
fuscous , t. a. line even, geminate, with fine bluish center, angulated. Ordinary
spots small, blue gray, the orbicular oblique. There is a brown shade over the

median space and subterminally before the s. t. line. T. p. line bent opposite
the cell and most ])rominentIy exserted between veins 3 and 5, even, gcininato,
the inner black line most distinct, filled in with a bluish white shade which
also follows it and obtains, within the s. t. line, to apices; terminal dots sub-
continuous; fringes fuscous. At base there is a black streak before the nngiila-
tion of the t. a. line and one below it on internal margin. Submedian fold
marked with blackish across the median space. Hind wings bright yellow willi
broad black borders and whitish fringe; beneath pale, with a small discal spot
and the border repeated. Body parts like the fore wings. Expanse 15 to 26
mm.

One fresh specimen from British Columbia, collected by the late (J.
II. Crotch, in Mus. Comp. Zool. Cambridge. One rubbed specimen
from Colorado, collected by Theo. L. Mead, No. 19.

Hadeiia clelicata, Grote. — 9- — The eyes are naked, the thorax with
divided crests, tlie dorsum of the abdomen provided with reduced tufts. The
antennje are simple, pubescent, weakly brush-like beneath. A medium sized,
dark purpl^' brown-black species, with a slight mossy green shading on the
forewings at base, on the ordinary spots and along the subterminal line, accom-
jianying the markings. Median lines faint, geminate, the outer scalloped, the
inner angulate. Orbicular moderate, black ringed, very near the t. a. line.
Claviform unusually large, prominent, distinctly black edged, extending across
the median field to the t. p. line. A paler wide shade extends obliquely beyond
these two spots across the median field. This character reminds us of Helo-
tropha reniformis, the species of Prodenia, etc., but it is here merely a broad
lighter tinting of the ground color. Reniform indistinctly outlined, molerate,
much shaded with black, the median shade visible obliquely within it over the
costal region. Three divaricate white dots on the costa ante-apically. .Sub-
terminal line tolerably distinct and continued, irregular, witii a rounded inward
sinus above the internal angle, and minute projected denticulations opposite the
cell, narrowly whitish, preceded by black points and shaded marks. A termi-
nal series of black points. Hind wings pale fuscous, with a faint line and discal
mark and a darker fuscous subterminal shade. Underneath with discal marks
and very faint shaded fuscous common lines. Thorax, head, and appendages,
concolorous with fore wings; faint black stripes on the tegulse. Expanse 38
mm.

IIOMOIIADEXA Grote.
In this genus the ovipositor is extruded shortly. This is furnished
with a row of distinct teeth, shorter in //. badistriga, and longer in
IT. Kappa. Between the teeth, along the groove, there is a stouter
moderately dense coating of long hair.

Iloiuoliadciia Kappa. — n. s. — 9- — Wood brown, more purely brown
shaded subterminally. Median lines black, evident, approximate, fused by a
black streak below the median vein, so that together they resemble the figure
of the Greek letter K. A series of subterminal black dashes as in H. badiUriija,

that opposite the cell the longest. No traces of the ordinary spots. A terminal
sublunulate black line. Hind wings fuscous with a faint median line, darker
and not whitish at base, as in H. hadistriga, than which this is a larger species.
Beneath dark fuscous with subterminal common lines, distinct and subdentate
on hind wings, within which the color is paler, and with inconspicuous discal
spots. Body concolorous. Expanse 40 mm.

Hab. Kansas, Prof. Saow, No. 167.

I have a specimen from California, which is in poor condition, and
which shows a superficial resemblance to this species in the disposition
of the median lines. It is, however, smaller, diiFerently colored, and
appears to me generically distinct; the ovipositor is not visible exteriorly,
and the abdomen is differently shaped terminally.

Pyrrhia angulata, Grote 5 9-~"The fore tibiae without spines exclude
the species from Chariclea, and I am led to believe it congeneric with Pyrrhia
exprimcns ■which, it resembles, and which appears to be the American represen-
tative of the Ruropean P. umbra (Hufn). The n&w species is easily recognized
by the angulated distinct median shade and the pale yellow secondaries.
Thorax and forewings brownish-red. T. p. line very fine, thrice waved, per-
pendicular. Orbicular finely ringed, concolorous, with central dot. Median
shade extremely prominent, angulated on the median vein within the base of
the clouded reniform, denticulate superiorly, even inferiorly, blackish. The
wing is lighter tinted from the base to this median shade. T. p. line black,
very oblique, heavily marked, followed by a dark shading over the subtermi-
nal space. S. t. line uneven, interspaceally scalloped ; fringes bright tinted;
an extremely fine marginal line. Hind wings light yellow with blackish bor-
ders narrowing to apices and internal angle. Beneath yellow, the costa of
secondaries and the narrower terminal band rosy speckled and tinted. Two
black discal dots on the forewings on which the transverse band is blackish.
Expanse 36 mm.

CATOCAL.A, Schrank.

I am happy to know that a more general interest in the species of
this beautiful genus has followed the publication of my paper on the
subject in these Transactions under the date of January, 1870. The
determinations I then made, the material upon which they were based
being deposited in the collection of this Society, allowed Mr. Herman
Strecker an opportunity to determine his material and publish some
generally good and useful lithographic plates of the species. Unfor-
tunately, the text accompanying these plates, is the work of an unsci-
entific person, whose most harmless idiosyncracy is a disregard of the
rules of literary composition.

94 AUG. R. GROTE.

^Vhilc these plates have been of great service in disseminating in-
formation on the genus, and while, from the circumstances detailed
above, I can only endorse the accuracy of the determinations, there
are one or two of the figures to which a proper exception should be
made. That of C. Faustina has led to the reierence of the .species
to the European C. Nupta by Mr. Moschler. I do not think the sup-
position is correct, and I have described the species comparatively in
the proceedings of the Boston Society of Natural History. The figure
of C. unijuga is also not good and looks as if it had been made from
a worn specimen, while I see no reason to doubt the determination.
An unacquaintance with specific characters in the genus, has allowed
Mr. Strecker to confound C. Meskei with C. unijvgn. The more
pinkish hind wings with their greatly naiTOwer and discontinued
median band, the more even testaceous gray primaries of C. Meshi
contrast specifically with the characters of the hind wings and the pul-
verulent, peppered, black and white, forewings of C. nniguga ; while
the median lines are dngle and not geminate in the slighter C. Meskei
from Wisconsin and New York. I pass over as valueless the imputed
identity of C. Arizonx with any of the described Californian species,
unfortunate as illustrating an unscientific animus, especially as it seems
likely that it has been followed by a re-description of the species as C
Aspasia Strecker. From specimens in the ^luseum of Comparative
Zoology of C. iUecta from Texas, I can, with certainty, refer the C.
Magdalenn of Mr. Strecker to this species, since Mr. Strecker himself
considered these specimens to belong to his supposed new species and
his meagre description bears out the fact.

Through the kindness of several correspondentvS I have been supplied
with much fresh material in the genus, so that I am now engaged upon
a second paper on our species of Catocala.

I content myself here with describing three species from the Middle
States and Canada, and two from Texas, all of which appear to me suf-
ficiently easy of identification without the assistance of figures.

C'atooala siniiila4ilis, Gro^e.— 9.— This species is intimately related
•with C. o6«c(t7Yt,soine\vIial as C. residua with C. insolabilin. C. residua has black-
ish fringes, the general color of the primaries is dusky ashen, without the linear
deepening in color above internal margin of C.insohibiHs,-wh\\(i the whitish gray
subterminal shade contrasts with the dusky tone of the wing. This species has
also a black oblique subapical shade beyond the subterminal line, more or less
distinctly followingthe teeth of the line and apparent sometimes within the line,
following the two prominent teeth of the t. p. line. This black shading is wanting

AMERICAN LEPIDOPTERA. 95

in C. obscura and C. simulatilis, which agree in the general smoki/ ashen primaries
and the white fringes to the hind wings, but may be separated by the course of
the t. p. line. This, in C simulatilis, is much as in C. residua and the other species,
with two very prominent teeth and wide open subreniform, whereas, in C. ob-
scura the line is more perpendicular and presents a series of fine teeth. The
resemblance is otherwise so great between the two that other comparison or
description seems unnecessary. Since I only know males of C. obscura and
females of C. simulatilis, I thought that my specimens of the latter might
belong, as the opposite sex, to C obscura. Such a sexual difference would be
quite new and unusual, and I cannot now be blamed for not adopting such a
determination. Expanse 65 mm.

Ohio, Dr. Hodge, two specimens.

Dr. Hodge has kindly communicated to me a specimen of C. reudua
taken in the same locality, and this species has also been taken in con-
siderable numbers in Chatauqua County, New York, during the present
summer.

Catocala L<evettei, Grote. — %9- — Forewings pale smooth greenish
gray, with very fine black transverse lines; the t. a. notched on s. c. vein,
thrice rather deeply waved. T. p. line exserted opposite the cell, with a more
prominent tooth, edged outwardly with white, the narrow open subreniform
white filled. Subterminal line dentate, whitish filled between fuscous shades,
from vein six a fuscous shading crosses the terminal space obliquely to below the
apices. Terminal black interspaceal marks, followed by white, very distinct.
Thorax like forewings, with mixed black scales on the collar and tegulee.
Hind wings black with blackish fringes. Abdomen above with a blackish shade.
Beneath, the body parts are white; second joint of palpi black. The wings are
white at base, with narrow pale interspaces between the bands, and resemble
generally the other species. Expanse 45 to 50 mm.

Indianapolis, Mr. J. W. Byrkit.

The smallest species of black winged Catocala, except C. tristis, yet
discovered. Smaller than 0. fiehilis, and with paler forewings, appear-
ing like a minature C. Rohinsoni.

I name this species with great pleasure after my kind friend, Dr.
Levette, of the State Survey of Indiana.

Catocala innubeus, var. flavidalis.

I have received from Prof. S. A. Forbes, Xorraal, Illinois, a specimen
with the number " 2" attached to it, which resembles C. innubens in
evert/ respect, except that the hind wings are dark yellow instead of
orange. The condition of the specimen does not allow of the sugges-
tion, that this change of color is owing to etiolation.

9G AUG. R. GROTE.

Catooala adopfiva, Grote. — 5 9- — Anterior winces wood brown, dis-
tinctly shaded with clicstnut brown subferminally and before tlie t. n. line.
The t. a. line is black, distinct, slightly three flexed, broad and diffuse superiorly.
Subreniforni larger than in 0. innuhens, black circled, filled with chestnut brown,
closed. T. p. line with two prominent, subequal teeth, else not dentate bi t
slightly waved with a rather deep inflection above vein 1. Subterminal line
black, dentate, preceded by a whitish shade, obsolete on costal region. Hind
wings deep yellow with the median band oblique, not rounded as in innuhens,
continued, lost in the fuscous hairs of the internal n»argin, angulated opposite
the ante-terminal constriction of the marginal band which is very deep and
sometimes nearly interrupts it. Beneath both wings yellow with the black
bands narrower than in C.^nnubens. Expanse 64 mm.

Dallas Co. Texas (Boll).

A number of specimens in the Museum of Comparative Zoology.
The different tone of the primaries, the larger chestnut brown sub-
reuiforra and the shape of the black band of the hind wings, suffi-
ciently characterize the species, and separate it from C. innubeiis, a
species also taken numerously by Boll in the same locality.

Catoeala eoelebs, Grote. — 9' — Allied to C. Consors; smaller, the ab-
domen fuscous, the median band of the hind wings broader, more even. Pri-
maries ashen, shaded with black. Median lines broad,' velvety black, distinct,
continued. T. a. outwardly oblique, widely indented submedially, the extra
basal space deepening in tone to the line which is followed by a whitish shade
over the median space anteriorly. Subreniform pale, large, open to the t. p.
line which is siromjiy and regularly dentate, without the usual discal projection.
Tbs t. p. line is followed by a deep brown shade after which the broad whitish
subdentate subterminal shade band crowns the wing. Terminal space ashen,
deepening outwardly. Hind wings light bright yellow, with a broad tolerably
even median band continued, and joining blackish hairs on internal margin.
Tern)inal band wide, comparatively even on its inner edge, enclosing a large
distinct yellow apical spot, and with the yellow color appearing inferiorly as a
line upon the margin. Fringe blackish. Beneath yellowish, deeper toned on
hind wings with brownish marginal, and wide even black median bands. Ex-
panse 64 mm.

St. Catharines, August 18, No. 182, Geo. Norman Esq.

Catocnla aiina n. s. — 5- — ^'^^ moderate, larger than C. potygama. Fore
wings eltar wiiitis'li gray, more purely white on the median space before the
reniform and over llie subterminal space. Ordinary lines approximate. T. a.
line, geminate, black, superiorly diff"useand running evenly outwardly obliquely
to below the median vein opposite the lower margin of the subreniform, which
it nearly touches, and with which it seems to be connected by a prolongation of
the black scales; below this angulation it runs downwardly sinuously to inter-
nal margin. Reniform rather large, black ringed, irregularly outlined supe-
riorly, with an interior aunulus, lying in a more bluish gray shade than the
rest of the wing. T. p. line exserted, angulate, geminate, with a single sharp

tooth opposite the cell, below which it is slijjhtly acuminate on the interspaces
forming a deep sinus before the margin nearly attaining the t. a. line. Sub-
reniform whitish, colored by the pale oblique shading on the median space
before the reniform, open. Subterminal line indistinct, well removed from the
margin ; terminal points small. Hind wings dusky or deep yellow. Median
band oblique, rather narrow irregular in outline, constricted before it ceases,
not attaining the internal margin. Hind border with lunulate interior edge,
deeply constricted, perhaps sometimes entirely interrupted before anal angles.
Avery inconspicuous and reduced apical intrusion of yellow scales. Body part
pale, abdomen somewhat yellowish. Beneath, dull pale yellowish with narrow,
bands and witli the hind wings stained inferiorly with orange yellow. Expanse
56 mm.

Texas (Boll. No. 104).

The following is a list of the seventy-three species of the genus in-
habiting our Territory. In addition, a single species, C. electilis WaJk.^
is described from Mexico. I look for the number to be considerably
increased so soon as California and the South- West become thoroughly
explored. Even as it is, vee have twice as many species as are found
in all Europe. Names in the following list preceded by a ("j"), I have
not been able to attach to any species. The sign | indicates erroneous
determinations; || indicates that the name has been previously used.

Description ot new species of DIURXili liEPIDOPTERA
fonnd in North America

BY W. H. EDWARDS, COALBURGH, W. VA.

Apatnra lieilia, n. sp.

In markings allied to Celtis, but with the shape of CJi/ton, the
primaries being more produced and hind margin more excavated than
in CeHis ; the hind margin of secondaries more sinuous and the inner
angle more produced.

Male. — Expands 1.8 inch. Upper side of primaries next base and
partly in the median interspaces, and of secondaries throughout, light
red-brown ; the remainder of primaries, which comprises the apical
area to median and to cell, and the discal portion of the median inter-
spaces, fuscous ; hind margins bordered narrowly by fuscous ; both wings
have a submarginal black stripe and a little anterior to this, a second,
which on secondaries is either very slightly crenated, or is crenated next
outer angle and serrated posteriorly ; primaries have a transverse discal
row of seven white spots arranged in a double curve, the first two and fifth
nearly equal, the third and fourth minute, the sixth and seventh, near
inner margin, equal, rather smaller than the fifth and sometimes con-
fluent; midway between this row and the margin is a second row of
white spots and ocelli; the spots, two in number, being placed on the
upper sub-costal and the discoidal interspaces; the three ocelli, on
the lower sub-costal and the median interspaces, are black, rounded,
the upper one small with an indistinct pale iris, the others large,
nearly equal, and each surrounded by a pale brown nimbus; in the
cell two transverse, equal, sub-reniform spots, one at the outer ex-
tremity, the other near the middle; these spots are obscure brown
centrally, black at the edges, and are separated by a space that is
white irrorated with brown scales.

Secondaries have the costal margin fuscous; upon the extra discal
area a series of six black ocelli arranged as in Clyton and Celtiti, the
second from costa largest and back of the line, the sixth minute, the
others nearly equal, rather more than half the size of the second ; each
surrounded by a shade slightly paler than the ground, and several
having within small eccentric clusters of blue scales; on the middle
of costal margin a white patch, and five small white spots in line with
this pass round the extremity of the cell ; in the cell two faint fuscous
spots; fringes white in the emargi nations, fuscous at the ends of the
nervules.

104 WM. II. EDWARDS.

Under side of primaries chestnut-red at base below tlie cell ; also
within the cell next base, but partly covered with gray, especially
along the sub-costal nervure ; remainder of wing pearl-gray, showing
a brown sub-color on disc and in the middle of each interspace on
the apical area, and at inner angle; the gray becoming suffused with
pale blue as it approaches the hind margin; this margin narrowly
edged with yellow-brown; the sub-marginal lines repeated, distinct,
blackish-brown ; the white spots repeated, enlarged, and in addition, a
white patch in the outer row on costa ; the lower spot of this row, in
discoidal interspace, nearly conceals a small ocellus, a narrow edge of
black being discernible on the anterior side, and the yellow iris being
nearly complete ; the other three ocelli re-appear, enlarged, each with
blue scales and a well-de6ned yellow iris; the cellular spots as on
upper side, the intervening space being clear white.

Secondaries pearl-gray, tinted with blue near hind margin ; the
gray shade least dense on the disk next before the ocelli, allowing a
brown sub-color to appear; the sub-marginal lines repeated ; the inner
margin also bordered by a brown line; the white discal patch and
spots repeated, and the line of spots extended across the wing to inner
margin, following the course of a dark wavy line; the spots in the
cell distinct, being transverse bars, the interior one prolonged into the
next upper interspace; the ocelli repeated and each containing a
large blue patch and edged by a narrow yellow ring which itself is
edged indistinctly by fuscous ; an additional ocellus on the inner uuir-
gin, small, oval, also marked with blue.

IJody above reddish-brown, beneath gray on thorax, yellowish on
abdomen; legs ochraceous, the tibiae gray; palpi clear white, fulvous
above and at tip; antenna3 yellow fulvous partly annulated with
white; club fuscous at base, yellow at tip.

clining to ochraceous, mottled as in primaries; the spots entirely
destitute of silver.

This species resembles Enrynome in size and shape. The first
examples % % seen by me were brought in by Dr. Hayden's last

Upper side deep fulvous, spotted with black; the Iiind niarj^ins of
primaries fuscous, preceded by a series of rather indistinct yellow
lunules, near the apex somewhat replaced by white ; the sub-apical
patch and that at inner angle dull ferruginous ; the spots arranged as

outer portion fuscous, the inner ferruginous, and containing a series
of small yellow lunules; a large black patch on middle of costal mar-
gin confluent with a spot at end of cell; fringes fuscous at ends of
nervules, yellowish in the interspaces.

Under side brown over basal area and along the hind margins, paler
across the discs, grayish sub-apically, and wholly streaked with darker
brown ; the extra-discal points black ; within the incision of primaries
and along the whole margin of secondaries a series of narrow blue-
green lunules edged by black; in the darker examples these lunules

extremities pointed ; sometimes the lower limb is thickened; and some-
times the upper limb is slightly bent.

Body brown-fulvous, below gray-brown, light on the abdomen; legs
gray-brown ; palpi black in front, gray with fulvous hairs interspersed
at the sides; antennae brown above, ferruginous below; club black,
tip ferruginous.

Female. — Expands 2 inches. The extra-discal region paler than
the basal; the submarginal spots much enlarged, lanceolate, indistinct.
Under side as in the male, the markings often much obliterated; silver
spot as in the male.

Found in California and Oregon, and allied to Progne. I formerly
described this species from scanty material, but as I have received
from Mr. Edwards a full series in both sexes, I have thought it well
to rewrite and amend the description.

Tbecla Siva, n. sp.

Male. — Expands 1 inch. Upper side castaneous, slightly brown at
base, the costal margin of primaries and both hind margins rather
broadly bordered with fuscous; secondaries have two tails, the outer
one short, the other long, .IG inch, both dark fuscous, tipped with
white; fringes fuscous.

Under side light fulvous, washed with pale metallic green, densely
on the costal and upper part of hind margins of primaries, and over
the whole of secondaries ; a common pure white band crosses the discs
of both wings, on primaries a little convex outwardly, and formed of

AMERICAN LEPIDOPTERA. Ill

lunules which are not quite confluent; on secondaries slightly wavy,
and confluent; on the basal side of this band the fulvous ground color
is deeper than elsewhere, and on secondaries several of the white spots
are edged by a line of black scales ; between the band and base no
spots or markings on either wing; secondaries have the hind margin
edged with white, the outer angle fulvous ; the interspaces along the
margin between the discoidal nervules and anal angle gray, caused by
black scales on a white ground ; on the lower median interspace above
the gray patch is a rounded blackish spot on ferruginous ground, and
this as well as the next patch on either side is surmounted by a black
lunule; anal angle black.

Body gray brown above, beneath dark brown with white hairs inter-
spersed, the abdomen yellow-gray; legs dark brown and white; palpi
white, fuscous at tip ; antennae annulated white and black ; club black
tipped with pale fulvous.

From 2 S taken by Mr. Henshaw at Wingate, Arizona, July, 1874.

This species is allied to Casfah's and Smilacis, being of similar size
and shape. On the upper side deeper red than CasfnNs, on the under
side there is much resemblance to Castalis in the shades of color and
in the common band. But this last is much less irregular than in
Castalis, in which the separate spots that compose the band are not
confluent and the two in the median interspaces are much behind the
line of the rest; in Siva the line is scarcely broken at this point and
is confluent; in Castalis are two conspicuous white spots nearer base
of secondaries which are not represented in JSiva. Smilacis is fuscous
on upper side, and below is most like Castalis, the band being very
irregular and the two spots next base appearing.

Catooala Kdifha.

Midf. — Expands 3.3 inches. Primaries lif^ht gray brown, crossed
longitudinally from base to a point just below apex by a blackish brown
stripe; the transverse lines distinct; the basal nearly entire from the
costa to middle of sub-median interspace, and there serrated in the
form of the letter W, the middle serration being very small; the
elbowed line has two prominent teeth, the upper one projecting about
one-tenth inch ; following these a deep ob-ovate sinus that reaches
nearly to the basal line; on the lower edge of this sinus the line is
twice serrated and then forms a re-entering angle to submedian ner-
vure ; a wavy gray serrated stripe crosses the extra discal area, ante-
riorly following the course of the elbowed line, but posteriorly nearly
parallel to the hind margin; within the margin a series of brown
points in the several interspaces, each on a gray streak coming from
the margin ; reniform bright brown, edged on the basal side with
black. Secondaries bright rosy red ; the median band rather broad,
contracted on the middle on the outer side, even edged and with a
circular curve on the inner side, terminating in a blunt point a little
within the abdominal margin ; the marginal border broad, and some-
what sinuous within posteriorly; the margin narrowly edged with yel-
low white, with fringes of same color.

On the under side the red shade covers rather more than one-third
of the wing, but is partly wanting on the submedian interspace out-
side of the median band.

Maniestra Inbens, n. sp.

% 9 • — This species resembles in appearance the European M. bras-
sicse and should replace that species in the " List." It is equal sized
but more variegated in color and more lilac tinged and wants the
terminal claw to the fore tibiae which distinguishes the European
species, for specimens of which latter I am indebted to the courtesy
of George Norman, Esq. Blackish with a faint lilac hue. Eyes
hairy; abdomen strongly crested on the middle segments. Transverse
lines black, indistinctly geminate, lunulate or waved. Claviform rather
wide and obtuse, black margined. Orbicular full, subquadrate with
pale or whitish filling, continuously black ringed. Median shade per-
pendicular, dentate. Reniform large, discolorous, filled in with white,
with a yellowish stain and with a darker center, upright, not kidney-
shaped, rounded superiorly, straight at base. Subtermiual space paler
and lilac-tinted, becoming yellow-brown before and along the whitish
subterminal line which is continuous and shows the median dentations
distinctly. Terminal black cuneiform marks evident. Secondaries
wholly brownish fuscous with pale fringes and vague terminal line.
Beneath paler with common vague transverse line and discal marks
most distinct on hind wings. Expanse 4.5 mm.

Hab. Canada, Eastern and Middle States.

Heliothis cupes, n. sp.

%. — Fore tibise with a longer inner and shorter outer terminal claw; all the
tibiae spinose. Forewings yellowish gray with all the veins finely marked by
paler scales. Markings distinct. Basal half line geminate, pale centered, the
inner blackish line most distinct. T. a. line geminate, the blackish component
lines equally marked, slightly arcuate and uneven. Ordinary spots with darker
centers and narrow black annuii pale margined within. Orbicular very near
.the t. a. line, rounded, well sized. Eeniform with a pale central indistinct
curved streak. T. a. line a little indented opposite the cell, the pale center
more evident than the component lines, running inwardly below the reniform
and narrowing the median space inferiorly. Median shade visible below the
reniform, approximate to the t. p. line but divergent to the internal margin.
The pale subterminal line is preceded by black cuneiform marks most distinct
medially. Terminal line black, distinct, preceded by a pale line, broken by

the veins. Fringes indistinctly interlined at base and interrupted by paler
at the extremities of the veins. Hind wings pale at base, with the veins soiled
with fuscous and with broad blackish borders narrowing inferiorly and cen-
trally interrupted with pale, as is usual in the genus. Beneath very pale yellow
gray, with distinct black discal marks and an outer curved transverse line, dis-
continued inferiorly, on both wings. Expanse 30 mm.

Appears to belong to the group with peltujcra, dipsacea, etc.; the
fore wings widen more outwardly and the markings are very distinct.

Cloopliaiia occata, n. sp.

9.— The eyes are naked. The frontal vestiture converges from the sides but
conceals no clypeal protuberance. Tibise unarmed but the fore tibiae have a
blunt and short claw on the inside and a very short process outwardly. Collar
pointed medially. Abdomen untufted. Collar above black, below gray-brown,
tipped with pale gray-brown. Thorax pale gray-brown. Anterior wings gray-
brown. Basal half-line indicated. Median lines obsoletely geminate, very
approximate below the median vein. Median shade black, very diffuse, almost
entirely filling the median space below the vein and bringing into relief the
small concolorousclaviform. Ordinary spots concolorous, small, subequal. Sub-
terminal line consisting of whitish streaklets and points preceded by black
longitudinal linear marks of unequal length and distinctness. Subterminal
space shaded with whitish gray especially below vein. Fringes ciieckered
black and brown. Hind wings whitish at base with soiled veins and rather
broad, shaded and even blackish hind borders. Abdomen pale. Beneath with
a common line broken into dots on the secondaries which are whitish, irrorate
on costal region and have diffuse blackish borders. Head black with a pale
interantennal line and pale oral squamae and palpi. Expanse 27 mm.

Ortliosia tlisliclia, Grote.

^. — Eyes naked, with lashes; tibiae unarmed. Thorax and abdomen un-
tufted, the latter conical. Fore wings of a peculiar stoue gray, sparsely inter-
mixed with black scales, paler to the prominent brown median shade, more
brownish beyond this. Basal half line faintly marked, angulate. T. a. line
geminate, outwardly oblique to submedian fold below which it forms an inward
angulation on vein 1. Orbicular obsolete. Median shade distinct, brown, out-
wardly oblique to median vein where it approximates to the reniform and forms
a slight rounded outward angulation thence still outwardly oblique to internal
margin. Reniform yellowish, somewhat medially constricted, distinctly out-
lined, with an inferior blackish stain. T, p. line geminate, sinuate, well re-
moved outwardly, the component lines equally distinct. Subterminal line pale,
subobsolete, indicated at costa by two distinct deep black triangulate marks,
the lower tiie larger and showing also a small black inferior point on the suc-
ceeding interspace. Very faint indications of other black accompanying points.
Fringes obsoletely blackish dotted. Hind wings wholly blackish fuscous. Body
like forewings in color. Beneath paler, irrorate; hind wings with an obscure
discal point, the common transverse line faint. Expanse 27 mm.

Perhaps this is Mr. Morrison's Caradriiia dlsticha) if so, Mr.
Morrison's "reneric reference is incorrect.

AMERICAN LEPIDOPTERA. 115

Agrotis excellens, n. sp.

S 5 . — The type of auxiUaris has the costal region from the base
outwardly and the collar ashen. A second specimen, received from
Mr. Belfrage, agrees with the type. Another Texan specimen differs
by the costal region and lower half of the collar being light brown and
contrasting. Otherwise the specimens nearly agree, differences of color
excepted. In particular the specimens have the wide secondaries and
narrow primaries in common. Credit is due to Mr Morrison for the
determination that the last named Texan specimen may be considered
to belong to auxiUaris. I had sent it to Mr. Morrison determined as
a new species together with the type of auxiUaris. From Mr. Henry
Edwards I have now received four specimens in excellent preservation
which agree very nearly with the Texan specimen above alluded to but
differ by the broader primaries and smaller secondaries as well as in
color and some details of ornamentation. The collar is produced in
front and there are slight metathoracic tuftings. I have noticed
dorsal crestings in saucia also, and it is evident to me that our observa-
tions on the genus are as yet far from complete. The ground color is
rich purple brown with the costal edge, the internal margin and the
subterminal space shaded with white. The large stigmata are shaded
with whitish and the reniform is less kidney shaped than in auxiUaris.
The males have these portions of the wing, except the stigmata, more
of a bright ruddy brown. Compared with auxiUaris the subterminal
space seems a little narrower. The claviform and the pale ray above it
are like auxiUaris. The species seems a little stouter bodied. Above
the hind wings are similarly colored, while less ample, but beneath there
is but faint trace of the common line and the terminal dark border is
obsolete in excellens, in which the under surface of both wings is more
irrorate than in auxiUaris. Expanse 40 — -iG mm.

Heliophila ligata, n. sp.

■J, 9- — This slender species has pure white secondaries and fringes in the
female while in the opposite sex these are slightly soiled. Fore wings whitish
ocher-gray, faintly purple tinged, with the veins obsoletely white marked and
accompanied by longitudinal blackish shades. Median nervure covered by a
white streak, culminating in a white spot relieving a single inferior black dot,
and accompanied by a black shading which continues diffusely to external
margin, and leaves a clear ochery streak above it on the cell, reaching beyond
the dotted transverse line. T. p. line indicated by a series of black uervular
points. Very minute marginal black points; fringes a little paler than the
wing. Thorax and head like primaries. Beneath without discal dots or com-
mon lines; a terminal dotted line on both wings; primaries and costal region
of secondaries somewhat rosy gray, else the secondaries are whitish, subpellucid.

This may possibly be Mr. Morrison's variety of PhrarjmitUUcola.
It is a distiuct species and does not accord well with any of Guenee's
descriptions that I have yet been unable to identify. From Mr.
Morrison's remarks it cannot be identified with certainty so that in
case it is the same T must be excused from adopting a name proposed
for a variety, not willingly believing that it could be taken for a variety
of phra(jm itldicola.

I'rotlijniia orgiao, n. sp.

% • — Tlie palpi are long while in other respects the species agrees with rosalba,
which Mr. Mo-rrison has referred to this European genus of which I have seen
no European representatives. The neuration has not been studied and the
generic reference is not assured. The colors and appearance of this much
smaller species recall the European Xanthodes malvae. The fore wings are tri-
angulate with sharp apices. Above these are deep lemon-yellow, all the lines
obsolete. Two light purple dots on the cell indicate the reniform and two
obliquely placed similar dots probably indicate the position of the t. a. line.
The t. p. line is better indicated by purple marks expanded on internal margin ;
it is very oblique, a little rounded opposite the cell. The fringes and external
margin are washed with light purple. Hind wings and fringes wholly whitish.
Collar and head stone purple, thorax clear yellow, abdomen pale. Beneath
pale with a ruddy suffusion or irroratiou which especially clouds the primaries.
Expanse 20 mm.

BOI.INA.

Mr. Morrison refers nigrescens as identical with fasdolaria in a
recent paper, and since this reference, I am informed, has been made,
after consulting Iliibner's figure, I must ascribe it either to an un-
scientific motive or to a want of proper discrimination. I have iden-
tified Hiibner's fasciolaris in the collection of this Society. It is
totally distinct from the Texan ni<jrescens^ the primaries are narrower
and longer and have the large yellowish oval subterminal patch (within
which the t. p. line runs) and which is shown so characteristically in
Hiibner's figure. Mr. Morrison's fasciolaris must be considered as a
synonym oi' nlf/rescens. Intermediate between Bolliia and Sj/ncda are
two species found in Texas which differ by a sexual palpal distinction.
In the male the third palpal joint is short and thicker, liardly differ-
entiated from the second. In the female it is thin and elongate. The
male antennae are more loosely and lengthily ciliate and the legs are
slenderer. The male is more distinctly marked and is described as

AMERICAN LEPIDOPTERA. 117

Syneda deducta Morr. The female seems to be described as Syneda
pavitensis by Mr. Morrison. The second species is much larger and
appears to be undescribed. For the two species I propose the name
Cirrhobolina.

Texas. Both sexes in considerable variation as to the distinctness
of markings on the fore wings collected by Mr. Belfrage.

2. Cirrhobolina incandescent, n. sp.

Expanse 40 mm. 9 . — This larger species differs from deducta, by
the fore wings being uniformly ashen, shaded with brown along the
subterminal line which shows a superior black mark with a blackish
indistinct ringlet to the reniform and some blackish costal blotches,
else all the markings and lines obsolete. Hind wings as in deducta
but with the lunule ve7-j/ pale not deep yellow. The undersurface
differs from deducta in the obsolescence and fragmentary state of the
terminal black borders and the inconspicuous discal point on the
secondaries. Taken Dec. 1, by Mr. Belfrage and numbered " 17."

To the kindness of Mr. Henry Edwards I owe an opportunity of
examining specimens of Syneda Edwardsii Behr, Syneda ochraeea
Behr, Syneda socia Behr, Syneda adumbrata Behr, Syneda divergens
Bchr and Syneda Stretchii Behr, the latter is a later name for Syneda
Howlandii, Grote. *

Bolina ochreifiascia, Harvey.

This species very nearly resembles B. nigrescens in size and color
but may be sufficiently distinguished and is characterized by an oblique
median ochreous fascia whieh shows outwardly the brown median shade
line. I have adopted Dr. Harvey's MS. name. I have never found
B. pallescens G. and 11., in any of Mr. Belfrage's Texan collections
which I have examined since 1866. The type in the Society's collec-
tion was collected by Mr. Cresson in the neighborhood of ^evf Braun-
fels.

Jflelanomnia auriclnctaria, n, g. et sp.

% ■ — The antennae are very shortly and coarsely bipectinate and the
labial palpi are porrected and a little longer than usual. The hind
tibiae have two pair of spurs. The wings are elongate with arched
apices and more rounded than in Eupithecia. The little moth has
the appearance of Ci/matophora (Boarmia) being gray with transverse
dark lines. The inner line on the primaries is rivulous. An even

broader shaded median line, inwardly oblique and a little arcuated, is
angulated on the cell outside of a black cellular eyelike spot which
shows some central metallic scales and is more or less completely
surrounded by a metallic iris prominently visible in certain lights.
The outer line is double, rivulous, angulated opposite the spot and
obsolete on costal region. Subterminal line double, rivulous, including
superiorly metallic scales above and below a subcostal indentation of
the line. Hind wings paler with double median and exterior lines
not continued to costa. Beneath the primaries show the black and here
larger discal spot with a yellow iris very distinctly, as also metallic
scales between the double subterminal line. Secondaries darker than
on upper surface, irrorate, with faint lines. Expanse .75 inch.
Hab. Pennsylvania.

KOTE ON PAPII.IO GUNDIiACHIAXUS.

BY A. R. GROTE.

As compared with Machaon and Asterias the Cuban species differs
by the sinuate external margin of the fore wings while on the second-
aries the discoidal cell is much smaller and the nervules thrown off at
shorter intervals. The internal margin is folded in both sexes and in
the male is brought entirely over, while the surface of the pouch thus
formed is covered with whitish discolorous silky hair. The body is
ornamented with scarlet patches of velvety consistence as in certain
of the South American forms. I propose to make the species the type
of a distinct genus which I name Blakea after my friend Mr. Charles
A. Blake. Blakea differs by the metallic bands of the primaries which
in the tailed species known to me are opake.

Jiotesfin the Species of RHIPIPHORUS of the
United States.

BY GEORGE H. HORJ^, M. D.

The following essay is tlie result of a study made necessary by
an attempt to name specimens which have been from time to time
sent me.

The males have the antennae bipectinate or flabellate ; vertex in
front less convex and above more truncate than in the females; an-
terior tarsi feebly dilated, pubescent in most species, spinulose in two
only. The form of the vertex and punctuation of the head have no
specific value, while color has, if possible, still less. The prolongation
of the maxillary lobes seems not to have generic value, specimens of
Macrosiagon are before me in which the lobes are not at all visible
while in Rhip. Umhatus they are as long as in 31. dhnidiatus and
the near association of these two species would certainly be very
unnatural.

There are certain structural characters of great value which point
out an arrangement of the species much more natural than any here-
tofore proposed, and when reduced to a tabular form the recognition
of our species is made more certain.

In most of the species the prosteruum is very slightly 'prolono-ed
and the coxae are contiguous in their entire length. In Umbatus and
linearis the prosternum is prolonged into a slender process whicli is
nearly as long as the coxae and which separates them in nearly their
entire length.

Ih many species the second joint of the hind tarsus is much shorter
than the third and flattened and rather broad above. In crueutus alone
the second joint is longer than the third.

The following table will enable our species to be known.

Anterior coxae contiguous in their entire extent.
Anterior tarsi % spinulose beneath; elytra very acute.

Basal lobe of thorax with a strong elevation; second joint of hind tarsi

not flattened above flavipeililis.

Basal lobe of thorax transversely notched at tip; second joint of hind

best described under its varieties. The general characters of all are
as follows :

Thoracic lobe not elevated, tip obliquely truncate and concave. Elvtra
above nearly flat, feebly longitudinally concave, contiguous for a short distance
at base, rapidly narrowing to tip and acute. Body beneath (metasternum es-
pecially) very densely and finely punctured and clothed with fine silken pu-
bescence. Second joint of hind tarsus shorter than the third and rather
broadly flattened above,

ilia/e.— Antennae pale rufous, rami black. Vertex in front moderately
convex, sparsely punctured.

Var. 1. — Black, abdomen red, thorax rufous, elytra black with sub-basal spot
red.

The form described by Fabricius as tn'stis {/asciafus, niger Mels.)
is composed of the more diminutive specimens which occur more
especially in the Northern States. They are of a generally darker
color.

This species is distributed over our entire country south of a line
from New York to Kansas.

It will be noticed that this species varies in a manner similar to the
preceding. The only diflFerence that I can discover between the two
is in the punctuation of the under side of the body.

tarsi rufo-piceous.

il/a^€.— Antennae black, two basal joints testaceous.

Female. — Unknown.

Length .16 inch; 4 mm.

This species agrees with limbatus in having the anterior coxae sepa-
rated by a slender prolongation of the prosternum.

One male is known. Collected by Mr. Ph. J. Wild, in Kentucky.

Mr. Fred. Bates placed at my disposal a number of specimens with
the original labels, which formerly made part of the collection of
Count Dejean. These are as follows :

R. diinidiatus.

E.Jiavicornis= % (liiuidiatus.

CICINDELID.E.

AnihJycliiJa Piccolommii Reichc is cylindriformis Say. — After an
examination of the type of this species I am convinced that the views
already expressed by Lacordaire and licconte are correct- The species
is doubtless a male and identical with those in the cabinet of Dr.
Leconte.

CARABID^E.

Carabus fulgidus Gebler, in the cabinet of Baron Chandoir from
Alaska.

Carabus hortensis Fab. Specimens in the cabinet of Mr. Andrew
Murray of London, are said to have been collected in the Hudson's
Bay Region. Before the species is introduced into our lists it would
be better to await the occurrence of other specimens.

Calosoma subseneum Chaud. Kev. et. Mag. Zool. Jan. 1809, and
C. latipenne Horn, Trans. Am. Ent. Soc. June, 1870, are identical.

Omophron nitens Chaud., Rev. et Mag. Zool. 18G8, is labiatum Fab.

Omophron nitidus Chaud., loc. cit. is iiitidion Lee.

Evarthrus ovidum Chaud., Rev. et Mag. Zool. 1868, is certainly
identical with acutiis, Lee. There are positively no known characters
for separating it as a variety much less as a distinct species.

Anisodacti/lus haplomus Chaud., Rev. et. Mag. Zool. 1868. I
cannot see any valid reason for separating this from our common
riisdcns.

A. (Gi/nandrotarsus) elongatus Chaud., loc. cit. is opaculus Lee.
I have seen a tolerably large series of this species and find that it is
impossible to distinguish the two above indicated.

Ilarpalus occidcntalis Chaud., loc. cit. is /ratenms Lee.

Ilarpalus liobasis Chaud., loc. cit., does not appear to be a species
occurring within our fauual limits. It may be Mexican.

TUECIIICT.S, Lee.

Trechicus umbripennis Lee, is the Bcmbidium nigriceps Dej. The
synonymy has been determined by a comparison of specimens.

The synonymy of Trechicus needs some correction. Chaudoir
calls the above species a Perigona. Lacordaire places the latter as
synonymous with Mastigns. In the Catalogus ((iemm. ct Harold)

AMERICAN COLEOPTERA. 127

Perlgona is Somoplatus. Finally the same genus has been redeseribed
by Morawitz as Pentoplogenius, (determined by Leeonte). Until the
synonymy is finally settled the name TrecMcus nigriceps (Dej.) will
be retained.

T. pallipennis Lee. does not appear to differ specifically from the
above.

AMARA Bon.
A. rejiecca Putz. Three specimens of this species sent by Putzeya
and Chaudoir are identical with lacustris Lee, the latter being accord-
ing to Dr. Leeonte the rufimnna Kirby.

A. ohtusa Lee, does not appear to differ essentially from liyperhorea
Dej. In the type of the latter is seen a fine basal line near the hind
angles which is not evident in the former.

The species included in the division Amara (Proc. Ac. 1855, p.
346) may be known by the following table :
A. — Autennce not carinate.

Prosternum % with a large and moderately deep puncture.

128 GEO. ri. HORN, M. D.

A. iilNiiIariK, n. sp. — Form oval, robust, piceo-seneous, shining. Head
emootli, frontal impressions feeble. Antennae not carinate at base, pale rufo-
testaceous. Thorax one-half broader than long, slightly narrowed in front,
convex, sides moderately arcuate from the basal angles; apex very feebly
emarginate, anterior angles broadly rounded, base not sinuous, hind angles
nearly rectangular, not obtuse; surface smooth, shining, basal impressions
nearly obsolete. Elytra rather broadly oval, finely striate, strise entire, im-
punctured, intervals flat. Body beneath and legs, piceo-rufous, smooth and
shining. Length .38 inch; 9.5 mm.

Male. — Hind tibiae i)ubescent within, prosternum with deep puncture.

The form and general appearance of this species is almost exactly
that of callfornlta althouyli somewhat larger. It must however be
referred to the pre.sent group and by the presence of the prosternal
puncture in the male its place is near inslgnis from which it differs by
its more oval form, different color and smooth thorax.

Two specimens iu the cabinet of Dr. Leconte, from the island of
San Clemente on the coast of California.

The following species are the North American representatives of the
sub-genus Bradi/tus Zimm.

Prosternum with side pieces smooth.

Prosternum % with oval punctured space.
• Meso- and metasternal side pieces punctured, scutellar stria verj' short or

entirely v/anting exarala Dej.

Meso- and metasternal side pieces smooth, scutellar stria very long.

latior Kby.
Prosternum % not punctured but feebly longitudinally sulcata in both sexes.
Meso- and metasternal side pieces smooth, scutellar stria lone;.

scptciitrionalis Lee.

Prosternum with side pieces punctured, meso- and metasternal side pieces

punctured, scutellar stria long Putzeysii n. sp.

A. glacialis Men., formerly placed in this group, is said by Putzeys
to be a Curtonofus (Lirus). I have seen only females.

A. cvarata I>ej.,furtiva Lee.

I cannot detect any difference between these two species. The
original specimens of the latter were immature and differed somewhat
in the punctuation of tlic thorax from exurata. A larger series from
intermediate portions of the country indicate the want of value of the
characters which appeared to distinguish the two species at first.

A. latior Kby., libera Lee, hyperborea % Lqc, Icevistriata Putz., oregona Lee.
Late collections from Colorado and New Mexico show the advisa-
bility of uniting oregona as a synonym. The type specimens of the
latter are smaller, darker in color and possibly somewhat more slender,
in all other respects the agreement is complete.

AMERICAN COLEOPTERA. 129

A. septentrionalis, Lee.

This is a somewhat more slender form than those which precede.
It differs notably by the absence of the oval finely-punctured space
on the prosternum and in lieu thereof a broad but feeble channel
extendino; from the tip of the prosternum nearly to the apical margin.
The same is seen in the female but to a much less marked extent.

A. Putzeysii, n. sp. — Oblong oval, piceous, surface feebly bronzed. Head
smooth, frontal impressions moderate. Antennfe pale rufous. Thorax one-
half broader than long, apex very feebly emarginate, anterior angles broadly
rounded, sides moderately arcuate in front, slightly sinuous and feebly narrowed
to the base, hind angles rectangular and slightly prominent, base truncate,
basal impressions deep, the outer limited by an obtuse carina extending one-
fourth the length of thorax, inner impression rounded, disc of thorax moder-
ately convex, median line moderately impressed, surface smooth, basal third
coarsely punctured, punctures sparser at middle. Elytra oval, slightlj' broader
than the thorax, surface moderately deeply striate, (less deeply at apex) strise
crenato-punctate, punctures gradually finer and more distant toward apex.
Scutellar stria long. Intervals flat. Body beneath and legs piceous, shining.
Pro-, raeso- and metasterna at sides, also the parapleurae of the sterna, coarsely
punctured. Abdomen moderately coarsely punctured at the sides especially
segments one and two. Length .32 inchj 8 mm.

One specimen, % , sent by Mr. Putzeys to Dr. Leconte, labelled St.
Pierre Miquelon, (Newfoundland.)

The characters giveu in the synoptic table will enable this species
to be readily recognized.

I take great pleasure in affixing to this species the name of an
entomologist whose labors have always produced good results and
whose kind reception and instruction will long be remembered by
myself.

ANISODACTYIiUS, Dej.

The large black Anisodactyli so abundant in California and Oregon
have been deemed troublesome to distinguish and all cabinets appear
to be in confusion on the subject. They appear to be separable by
well defined and easily seen characters. The following table is the
result of their study :

Intercoxal process and middle of second and third abdominal segments punc-
tured; punctures with short setae. Metasternum in front and behind punc-
tured.
Thorax feebly narrowed posteriorly, basal imiDressions very feeble, surface

entirely punctured seuiipuuetsitus.

Intercoxal process and metasternum smooth.

Thorax with broad but very shallow basal impression; elytra broad, sides

very distinctly arcuate coiii^obriiius.

Thorax with rather deep linear basal impression, surface of prothorax
much less densely punctured than either of the preceding species.

I have adopted the name semipunctatus for the first species, although
the name similis has priority, for the reason that the latter applies not
to the mass of specimens obtained but rather to a very rare variety,
distinguished only by its slightly narrower form.

The males of the three species have the terminal dorsal segment
coarsely punctured, while in the females the punctures are nearly
obliterated and the surface comparatively smooth.

PATROBUS Dej.
The species of this genus appear to have been unnecessarily
multiplied. Having lately had occasion to examine them closely the
following table has been prepared. Typical specimens of all the
species are before me with two exceptions fidvus and awjusticollis
Mann, which still remain unknown.

Disc of thorax convex, hind angles with a rather deep fossa; head behind the
eyes constricted.

Last two joints of maxiHnry palpi equal lonieicornis Say.

Last two joints unequal, terminal longer scptcntrioniM Dej.

Disc of thorax flat, sub-quadrate, hind angles depressed without fossa; head
not or very feebly constricted behind the eyes; terminal joints of maxillarj'
palpi equal.
Hind trochanter % one-third the length of the thigh and not differing from

that of the female rilgicollis Rand.

Hind trochanter % nearly half the length of the thigh and acute at tip,

that of the 9 normal aterriinus Esch.

Hind trochanter % nearly as long as the thigh, at tip slender and very
acute, that of the 9 scarcely differing from the 9 9 of the two preced-
ing californiciis Motseh.

Northern California.

The two unknown to us {/ulvus, angusticollis) should also doubtless
be referred to the same species with the other Arctic forms of Manner-
heim and Eschseholtz.

The last three species in the above table have a tolerably close
superficial resemblance. The thorax is rather narrower behind in
rugicoUis and nearly square in californkits. While noticing the re-
markable differences existing between the males it is well to recall a
similar difference existing between two species of Ptercstichus, rostra-
tiia Newm., and grandiceps Chaud., ( nee Leconte ). As .«een from
above no differences whatever exist, while the latter has the hind
trochanter long and slender almost precisely as in Patruhus calif ornicin'.
Similar differences between otherwise closely allied species may exist
in other places in the Carabideous series and these two instances are
specially noticed here together that attention may be directed to further
observation.

TRECHrS Clairv.

Three forms occur in this genus, the first with oblong elytra which
are nearly twice as wide as long and with five or six striae moderately
well impressed; the second with oblong oval elytra with distinct
humeri and four or at most five striae, the inner three moderately well
and the outer two very feebly impressed ; the third has broadly oval
elytra the stride nearly obsolete sometimes with the two nearest the
suture feebly distinct.

The following are the species .

T. rubens Fab., elytra oblong. — Occurs in Northern Europe and Nova
Scotia.

T. chalybseus Mann., elytra oblong oval.— Occurs in Alaska.

T. californicus Motsch., does not differ from the preceding. — Alaska, Cali-
fornia, Oregon.

T. micans Lee, I can see no difference excepting a somewhat paler color;
f ulcus Lee, is immature. — New Hampshire and Lake Superior.

T. ovipeunis Motsch., elytra broadly oval.— Alaska.

T. loevigatus Lce, does not differ from ovipennis. — California and Oregon.

BE^nBIDIUM, Latr.

Mann. This species originally described from Alaska occurs in Canada,
Michigan and Pennsylvania. It has been referred to Trechus by Chau-
doir, but the external maxillary lobe is formed exactly as in Amerizus
and the species should therefore be placed in that genus. Amerizus
spectahilis Mann., is well known to American students.

Tanijrhinits ningidaris Mann. This insect has also caused trouble
since the day of its publication. Mannerheim placed it near Rhlnosi-
vius, etc., notwithstanding its pentamerous tarsi. An admirable figure
kindly sent by Miiklin seems to show that it is a Staphylinide ! of the
Omalium group and Dr. Leconte suspects may be allied to Tn'jono-
demus Lee.

ENDOMYCIIID.E.

In a small pamphlet entitled " Endoraycici Recitati " published in
London, (bearing date May, 1873, but not issued until September,
1873), by llev. Mr. Gorham, the following North American species are
described.

Rhi/mhus minntus Gorham, 1. c, p. 56, is Alexia minor Crotch,
Trans. Am. Ent. Soc, May, 1873. The species is certainly a Rhi/m-
biis and not an Alexia^ and both minor and Llkei Crotch, must be
placed under the former generic name.

Aphorisfa Jttoiieralis Gorham, loc. cit. p. 45, is a perfect reproduc-
tion of the type of Mijcetina morosa Lee. For this species as well
as fsefa Lee, Mr. Gorham has erected a new genus as above indicated,
the characters of which seem entirely too trivial to be considered
valid.

SCAPHIDTID.E.
SCAPHIDIUM, 01.

The four species indicated in our lists appear to be merely varieties
of one, and are separable as varieties in the following manner :

Elytra with two red spots on each.

Elytra with three short rows of large punctures qnadrigiittaf mil.

Elytra with two short rows of large punctures quadripunctatum.

Elytra without rows of junctures obliteratum.

Elytr.a black without spots piceittn.

Varieties of the latter form also occur parallel with those of the
spotted form and should these differences be considered valid two
more species must be indicated I prefer to consider all as variations
of one form.

NITIDULID.?^.

IPS, Fab.

Our species formerly known under the name Ips have been placed
under the more recent name Pityophagus in the " Check List." With-
out desiring at this time to discuss the vexed question of priority and
the correctness of the use of the name Ips by Fabricius, it has seemed
to me desirable to place before the American students a condensed
review of our species.

I cannot agree with the author of the " Check" List" and with
Reitter (Verhand. des Naturf. Vereines in Briinn XII.), in uniting all
the species under one generic name, believing that the general form,
the structure of the head and the eyes distant from the thorax are
characters of generic value.

Ips. — Body oblong oval, depressed; head broader than long, deeply
inserted in thorax, eyes close to the angles of thorax. Elytra without
sutural stria.

Pityophagus. — Body sub-cylindrical; head nearly as long as broad,
prolonged behind the eyes which are distant from the thorax. Elytra
with sutural stria.

Our species of Ips are as follows :

Hind tarsi nearly as broadly dilated as the anterior, thorax broader at base

than apex Sub-Gen. IPS.

Hind tarsi slender not dilated, thorax' narrower at base than apex.

Sub-Gen. GLISCHROCHILUS.

Sub-Genus Ips.
Middle and hind tibiae % with the lower half suddenly broader.

Body black, elytra each with two large red spots obtlisns.

Middle and hind tibise not broader, similar in the sexes.

Body beneath black Tasciatus.

Metasternum, abdomen and pygidium red sanguiuolentus.

Sub-Grenus Glischrochilus.
Sides of thorax distinctly sinuate in front of hind angles.

Elytra reddish yellow, apical fourth, margin and humeri black; at middle
a round black sjwt joining the margin, base of suture and a small round

spot on each side black v couflueiitiis.

Elytra black with pale linear spots, one basal, one ante-median and two

side by side post-median rittatus.

Sides of thorax gradually narrowed to base not sinuate. Form elongate, legs
rufo-piceous J elytra black with a moderately large sub-humeral red spot and
a median interrupted fascia cyliudricns.

I. obttisus Say. Bost. Journ. I., p. 168.

Very little variation occurs in ornamentation, which consists of two
large red spots on each elytron, one slightly within the humeral angles
the other post-median. Length .36. — 48 inch; 9 — 12 mm.

134 GEO. II. IIOIIN, M. D.

Occurs in the Middle and Southern Atlantic States.

2>ustulatus, Reittcr, Vcrhiind. Naturf. vereinca in Briinn XII., p. 161.

These are all varieties of one species, the characteristic names given
the varieties will enable them to be determined readily. Reitter says
(loc. cit. note) that scxpustuhi/us and qnadrlatgnatus have four quad-
rangularly placed impressions on the front while /'(.S(7'«^».s has but two.
In the majority of all the forms before me there arc no impressions
whatever. Length .10 — .28 inch; 4 — 7 mm.

Occurs over the entire region east of the Rocky Mountains and also
in A'ancouver.

rubromaculaius, Reitter, loc. cit., p. 161.

The elytra are red broadly tipped with black, humeri and a median
round spot black. This is the normal coloration. In the form de-
scribed by Reitter, the median black spot is extended so that the red
is reduced to a short basal fascia with another post-median narrow
fascia interrupted at middle. We have in our cabinets enough of the
intermediate forms to show the identity of the two. Length .18 — .24
inch ; 4.5 — (i mm.

Occurs from Canada to Florida and Texas.

I. coiifliicntus Say., Journ. Acad. III., p; 195.

The elytra are more coarsely punctured than in any other of our
sppcies. The coloration has been already noticed. Length .18 — .20
inch ; 4.5 — 5 mm.

Occurs from Canada to Georgia.

The sides of the elytra are nearly exactly parallel. The elytra
are more coarsely punctured than any species except the preceding.
Length .IG — 20 inch; 4 — 5 mm.

Occurs in Canada, Utah and Oregon.

I. cylindrical Lee. New Species, 1863, p. 04.

Form more elongate than vittatus and more convex. The thorax is
slightly broader than long, the sides absolutely straight and gradually
converging to the basal angles which are sharply rectangular. The
coloration has already been uoled. Ijcngth .20 — .30 inch; 6.5 —
7.5 mm.

Occurs in California, Oregon and Nevada.

I might here notice a curious paragraph in lleitter's paper (p. 166).

AMERICAN COLEOPTERA. 135

After describing a new genus Ijisimorjyha, founded on a Mexican species
{striatopunctata)^ lie adds a paragraph which I here translate :

" I should have considered this species, Rhizophagus {Ips) cylindricus, Lee, did
not the diagnosis read as follows; ' thorace paulo angustiore, latitudine fere sesqici
longiore, lateribus rectis, angulis posticis rotundatis.' The striate punctate elytra
lead me to suppose that this species should also be referred to Ipsimorpha."

The Rhizophagus cylindricus Lee, and Ips cylindricus Lee, are two
very distinct insects and differ especially in the form of the anterior
coxas and the number of antennal joints, and belong to two distinct
families, It is very likely that Reitter has never seen the description
of the latter species.

PITYOPHAGUS, Schuck.

Two species occur in our fauna.

P. cephalotes Lee. Proc. Acad., 1860, p. 377. Color rufous, elytra piceous.
Length .20 inch; 5 ram.

Occurs in Pennsylvania.

P. rufipennis Horn, Trans. Am. Ent. Soc, 1872, p. 146. Body black, legs
piceous, elytra brownish red. Length .28 inch; 7 mm.
Occurs in Oregon and Vancouver.

All the specimens before me have the tip of the pygidium furnished
with a reflexed margin. This may be sexual.

Carpophilus rufus Murr. From my series I am convinced that this
species is melanopterus Er.

DERMESTID^.
PERIMEGATOMA, n. g.

This genus is suggested for several species occurring from Lake
Superior to Texas, California and Sitka, which agree with Megatoma
in all of its characters except in the antennal fossae. In the present
genus there are no antennal fossae whatever. The ornamentation, by
pubescence of the surface, resembles somewhat that of Megatoma,
there being two transverae undulating cinereous bands, the one at

There is a duplicate of Kirby's type before me. The elj'tra are
piceous, but near the posterior third luay be seen the eridences of a
paler transverse band.

To this species I refer certain female specimens brougTft by Mr-
Crotch from the Sierra Nevada 3Iountains of California, whieb vary
somewhat in appearance.

Specimen c, elytra with a sinuous transverse rufo-piceous band at
apical and basal third to which the pubescence is very closely adherent
causing the elytra to be conspicuously marked.

The distribution of the species is very wide, from Sitkha (Mann.),
Saskatchewan (Kirby), Lake Tahoe and Tejoti, Cal. (Crotch), Oregon
(Horn).

P. I'alsHin, n. sp.

This species resembles exactly in their form and vestiture those
described as variety c, above. The only differences are found in the
structure of the antennal club.

Male. — Club of antennje slightly longer than the funicle, first joint extremely
short but nearly as wide as the second, terminal joint more than twice as long
as the two following together and pointed at tip.

Female. — Club not longer than the funicle, first joint much shorter than the
second, terminal joint slightly longer thau the first two united and but little
longer than wide, oval at tip.

The pubescence of the elytra is decidedly bi-colored, being composed of
pale-brownish and greyish-white hairs intermixed, the former forming narrow
transverse bands in front of the rufous bands of the elytra. Length .14 inch :
?A mm.

Occurs at Tejon and Santa Barbara, Cal., (Crotch),

P. variogatiiin, n. sp. — Oblong oval, piceous or piceo-rufous, elytra with
two sinuous transverse bands of rufous with dense white pubescence. Head
and thorax densely punctured, covered witii intermixed pale-brown and white
hairs. Elytra oblong oval, sides sub-parallel, surface less densely punctured
than the thorax, color piceous with a sinuous rufous band at basal, and another
at apical third, rather densely covered with white pubescence, the remainder

of the surface with intermixed pale-brown and whitish hairs. Body beneath
densely punctured, sparsely covered with cinereous hairs. Antennae rufous or
pale-brown. Length .20 — .22 inch; 5 — 5.5 mm.

The specimeus before me are apparently all females. The antennal
club not lonpjer than the funicle, the first two joints nearly equal and
the terminal shorter than the other two united, oval and slightly
obliquely truncate on the inner side.

Occurs in Texas.

LUCANID.E.
L,UCANUS, Linn.

Lucanus placidus Say., is thought by Major Parry to have been
described from the female of elaphus, and he would therefore place
the name lenlus Cast., to that form occurring in the Southern and
Western States to which the name placidus has been attached by
American Entomologists. A comparison of the descriptions of Say
and Castelnau, leave no doubt in my mind that both are applicable to
precisely the same species, and should the views of Major Parry be
adopted, our so-called j)lacidvs must be nameless. I cannot, however,
agree with this view, and have no doubt whatever that the descriptions
by Say and Castelnau, apply to the same species which is that now
known as pfacidus by us. This name should therefore remain.

Platycerus coprulescens Lee, was previously described as oregonensis
Westwood.

SCARAB^EID^.
Choer-idium Lecontei H.aTo\d, appears in the Check List as a synonym
of Imteroidcs. This is incorrect. The former has the hind thoracic
angles very much more broadly rounded and the margin at the angle
very feeble and not at all reflexed as in the latter. It occurs in the
Southern States.

ONTHOPHAGUS, Latr.

The species of Onthophngus are few in number in our fauna, and a
careful examination convinces me that the number already given in
our lists must be reduced, several having been described from varia-
tions in color and the degree of prothoracic development in the male.
The species divide themselves into two sections.

Thorax of male protuberant in front, frequently with a long process more or

less deeply emarginate at tip Section A.

Thorax of male not differing from the female, both simply convex.. ..Section B.

TRANS. AMER. ENT. SOC. (18) SEPTEMBER, 1875.

138 GEO. H. HORN, M. D.

In the first section, evidences of a tendency to a protuberance of
the thorax in front, are distinctly visible in the female. When a .^lij^ht
protuberance does not exist in the female there are on the anterior
inarp;iti of the thorax two slight depressions visible, one on each side
midway between the median line and the anterior angle. The pro-
thoracic protuberance of the male varies greatly in development, in
its greatest size the process fjrms a plate of variable width, usually
much longer than wide projecting three-fourths as far as the tip of
the clypeus, more or less deeply eniarginate at tip and with tiie angles
thus formed divergent. In Hecate a slight process projects downwards
from the bottom of the emargination and is itself deeply notched form-
ing two small teeth, while in Janus a slight tooth is seen near the tip
of the diverging angles. From the size above described, the pro-
thoracic process may be reduced to a mere transverse tubercle. The
males of all the species have much longer, more slender and more
arcuate anterior tibiae than the females and the terminal spur is shorter,
more robust and more arcuate.

In the second section the form of the anterior tibiae furnishes the
only guide for distinguishing the sexes.

In nearly all the species the head is transversely bicarinate in the
two sexes,, and where the thoracic protuberance is strongly marked in
the male these carinas di^appear and in very nearly all the females ot
all the species the carinae are more strongly marked than in the males.
These two carinas are situated, the anterior on the clypeo-frontal suture,
the posterior on the vertex between the eyes.

The first section contains three species.

Body blaek, opaque, thorax finely granulate, elytra finely chagrined and
with two rows ol" fine granules on each interspace. Vertical carina of male
simple Ileeate.

Body bronzed or greenish, shining, thorax punctured, elytra usually sliiniug not
granulate. Vertical carina of male elevated at each extremity into a horn
of variable size or an acute tubercle JailUS.

Body black, sub-opaque, thorax sparsely punctured ; elytra very finely chagrined
and irregularly biseriately punctured. Vertical carina of male elevated at
each extremity into a long slender horn vellitiiius.

O. Ileoafe Vanz., hastalor Fah., latebrasus Fa,h., obtectus Beau v. , (So.yi Cast. —
Black, op:i(jiie, .-'jjarsely clothed with short greyish hair. Thorax moderately
densely granulate, median line at base very finely impres.sed. Elytra finely
striate, intervals finely chagrined and with two or three rows of fine granules.
Pygidium coarsely punctured, at base opaque and granulate. Body beneath
shining, coarsely but sparsely punctured. Length ..S4 inch; 9 mm.

Male. — Margin of head moderately refle.xed, in front elevated in a slender
triangular jjrocess, on each side slightly sinuate. Clypeus smooth at middle,
punctured and wrinkled at the sides, front and verte.x very sparsely punctate.
Clypeal carina feeble or absent, vertical carina arcuate and feeble, frequently

AMERICAN COLEOPTERA. 139

entirely absent. Prothoracic process broader at tip and emarginate and with
a feeble bidentate process from the middle of the emargination.

Female.— Anterior margin of clypeus without the slender process; surface of
clypeus coarsely punctured and transversely wrinkled. Clypeal carina strong
nearly attaining the side margin of the head, vertical carina more elevated
curved backwards at its ends. Prothorax slightly protuberant at middle or
with a slight depression ou each side of the middle of the anterior margin.

This species occurs abundantly over the entire rep;ion east of the
Rocky Mountains and varies in its development about equally in all
parts of that territory. Its size varies from .34 to .'JO inch, and at
the same time no varieties occur requiring special remark beyond the
generalities already given.

Bea-uv. .. icabricollis Khy., concinnus C ust., castaneus Me\s , cervicornis Khy.,pro-
tensus Mels., niger Mels. — Color variable, bronzed, greenish or cupreous, shining,
surface sparsely pubescent. Thorax sparsely and coarsely punctured, anteriorly
with a tendency to granulation. Elytra finely striate bi- or triseriately punc-
tate, Pygidium sparsely punctured, more densely and coarsely near the apex.
Body beneath greenish or bronzed, sparsely punctured. Length .30 — .16 inch ;
7.5 — 4 mm.

Var. Orpheus Panz., canadensis Fab., etc. — Surface metallic green or bright
bronze, shining. Thorax sparsely and moderately coarsely punctured.

Male. — Clypeal margin moderately reflexed, at middle slightly elevated and
subtruncate, surface of clypeus sparsely punctured. Clypeal carina nearly
obliterated. Vertical carina feeble at middle, elevated at each end in an acute
tubercle. Prothoracic process broader at tip deeply emarginate, angle diver-
gent and with a small tooth like process near the tip.

Va7\ subaeueus Beauv. — Thorax and elytra metallic green, the latter at base
and apex yellowish, the former slightly granulated anteriorly.

Male. — Clypeal margin at middle slightly elevated and not truncate. Verti-
cal carina at its ends elevated in a short horn. Thoracic process short broadly
emarginate at middle.

Far. striatulus Beauv., ca.staneus M.e\s., scabricollis Kby. — Piceous or piceo-
testaceous, surface bronzed. Elytra paler at base and ajiex.

Male. — Clypeus as in Orpheus. Vertical carina at extremities elevated into a
slender horn nearly as long as the height of the thorax. Thoracic protuber-
ance very small.

The females of all the above varieties agree in having the clypeus
deeply punctured and transversely wrinkled, the clypeal carina strong
and attaining the side margin of the head, the vertical carina still
stronger and slightly arcuate or sinuate. The head of this species in
form agrees with the preceding and has a similar sinuation on each
side at the end of the clypeo-frontal suture.

This species is widely diifused and varies so much in color and in
the degree of the development of the various peculiarities of the male
as to have caused it to have been described under so many different
names. It will be seen however that, as in Hecate, as the thoracic

140 GEO. H. horn,"m. d.

protuberance is developed the ceplialic carinae and horns become re^
duced to a minimum, while in the last variety in which the protuber-
ance is scarcely larger than in the female, the vertical carina at its
extremities becomes elevated into two long slender horns.

Occurs over the same extent of country with the preceding species.

O. vellltinuH, n. sp. — Black, subopaque, punctures bearing very short setre.
Thorax sparsely punctured, between the punctures extremely finely chagrined.
Elytra with sides regularly arcuate not narrowing posteriorly, surfiice verv
finely striate, strife very distantly punctured, intervals finely chagrined and
irregularly biseriately punctulate. Pygidium opaque very sparsely punctured.
Body beneath very sparsely but rather coarsely punctured. Length .:50 inch;
7.5 mm.

Male. — Clypeus nearly semicircular with a broad feeble emargination at
middle, surface coarsely punctured. Clypeal carina very feeble. Vertex
sparsely punctured, carina very feeble at middle, each end elevated into a
moderately long slender horn. Thorax slightly protuberant in front. An-
terior tibial spur strongly recurved.

Female. — Unknown.

This species recalls some of the varieties of the preceding but its
entire aspect is different. Its form is somewhat longer and the elytra
have regularly arcuate sides so that their form is nearly circular with
the emargination at base. It is probable that further collections may
produce forms in which the development more nearly approaches that
of the preceding species.

Occurs in Lower California and Arizona.

The second section contains those species without any trace of
prothoracic protuberance. The males are known by the form of
the anterior tibiae and by the smoother head. Two species only
are known.

Margin of clypeus at middle acutely notched tiiberonlirrons.

Margin of clypeus very feebly truncate at middle pensylvanicus.

O. tuborculirrons Harold, Coleopterologische Hefte VIII., p. 115; tuber-
culatus Zimm., mscpt. — Black, subopaque, surface feebly bronzed and very
sparsely pubescent. Clypeus acutely notched at middle. Thorax finely cha-
grined, sparsely punctato-granose. Elytra finely striate, surface finely cha-
grined, intervals biseriately punctate, punctures alternately placed and each
bearing a short hair; base and apex with small paler patches. Body beneath
piceous sparsely punctate; legs paler. Pygidium sparsely punctate. Length
.14 — .20 inch; 3.5 — 5 mm.

The sexes of this species do not greatly differ. The margin of the
head is moderately reflexed, acutely notched at the middle of the
cljpeus, the latter more coarsely punctured in the female. The clypeal
carina is short in the female and very nearly obliterated in the male ;
the vertical carina is also short divided at middle and formiu'' thus

clypeus.

Occurs from the Middle States to Florida, where it is very abun-
dant.

size, thorax much more coarsely and densely punctured, the clypeal
carina $ very feeble and the vertical carina strong and considerably
elevated.

Occurs rather abundantly from the Middle States to Kansas, Texas
and Florida.

AT.El^IUS, Ilarol-i.

In the Coleopterologische Ilefte XII., Munich, IS'4, liaron Harold
describes as new several North American species of Ataenius of the
group with toothed clypeus, without being aware that a paper inclu-
ding all the species of this genus had already been published in the
Trans. Am. Ent. Soc., 1871, p. 284—289. Having lately had an
opportunity of exauiining the types of Harold, the following is the
result :

At. attenuator Harold, Hefte XII.. p. 22, is abditus Hald.

.4^ texauns Harold, 1. c, p. 23, although possibly a true species,
differs from abch'tus in the manner that southern varieties of the latter
differ from the northern. 1 would prefer calling it merely a variety.

At. Lrronfci Harold, 1. c. p. 20, is certainly identical with ovatnlas
Horn, The latter was, however, described from a slightly worn speci-
men and the clypeal teeth were entirely removed and a renewed ex-
amination shows that rijllndrus Horn, is the perfect form, and the
latter name should therefore be substituted.

At. Horni Harold, 1. c, p. 19, is somewhat more cylindrical in the
form of the elytra but does not otherwise differ. The specimen from
which the species was described is unique in the cabinet of Baron
Harold, and with the examination made of it did not appear to differ
specifically from the preceding.

The following without toothed clypeus are described.

^4/. >i')cialis Harold, Bert. Zertschr., 1873, p. 174, is socialis Horn,
1871.

At. fvjurafor Harold, Hefte XII., p. 24. — A slender shining sp'ecies
near (jmcilis but with the punctures of the thorax coarse and widely
distant. A very distinct species. Occurs in Texas.

PHYTAL.US, Blanch.

Under thi? generic name a species {f/laberrimus Bl.) appears in the
Check List. On his return from Europe, Dr. Lecoute brought a speci-
men said by the donor to be Ldclmostcrna glaberrima Blanch., which
proved on examination to be a Ph^tatus and the species to which the
name L. (jhibe.rr !vi<i was attached in our cabinets was therefore sup-
posed to be erroneously determined, and Mr. Crotch substituted the
name t/htbra for that which it bore. A comparison made by myself
shows that the original determination was correct, and that the speci-
men given to Dr. Leconte although clo.sely resembling ijlubrrrima was
not that species. Phi/talns glaberrimus must be stricken from the list
and the name ijlaberrlita restored to its original position.

The genus I'hytalus has hov^ever represeutatives within our fauna,

AMERICAN COLEOPTERA. 143

one of moderate size resembling Lack. Burmeisteri and one smaller
resembling L. inana, the former from New Mexico and the latter
from Texas.

These species I hope to make known with a general revision of the
Lachnosternfe.

L,ACHBrOSTERlVA, Hope.

The following synonyms have been detected :

L. sororia Lee. is rufiola Lee. The antennas are nine-jointed in
both forms.

L. rohusta Lee. is crassismna Bl. The synonymy of ohesa with the
latter has already been noticed. I find robusta to have the antennae
distinctly ten-jointed agreeing with crassissimn in this and all other
characters.

CY€L,OCEPIIAL,A, Latr.
C. elegans Horn, is identical with dimidiata Burm.

LIGYRVS, Burm.

Three species of this genus have been separated on the dentation
of the galea of the mandible, niorio^ gihhosus and juvencus. I have
seen very good series of these species and, although some variation
does occur in the distinctness of the outer tooth, from age and wear-
ing, it appears to me that the three should be united under one name
(ffihbosus) as specifically identical.

Our species separate easily in the following manner:

Thorax impressed in front and with a small tubercle. Anterior tibiae tridentate.

Clypeus bidentate gibbosns.

Clypeus unidentate ruginasus.

Thorax not impressed nor tuberculate. Anterior tibipe subquadridentate.

Larger species, brownish or pieeous; mesothorax hairy relictiis.

Smaller species, black; body beneath not hairy rugiceps*

STRATEGUS, Hope.
Within our faunal limits are five species and while well known and
easily distinguished by those having all the species, it is not an easy
matter for others to name with certainty any of them excepting well
marked males of Antseus or Julianus. The following study is pre-
sented to remedy the difficulty.

Elytra with sutural stria visible, at most, for a short distance from the tip.

Anttens.

Elytra with entire sutural stria.

Sexes differing in form of thorax Julianas.

Sexes not differing in the form of thorax.

Galea of mandible with a long slender median tooth iVformon.

Galea without slender tooth.

Galea differing in the two sexes splendens.

Galea similar in the two sexes cessus.

144 GEO. n. HORN, M. D.

The most striking sexual character is found in the different arma-
ture of the thorax of the uiale. This however occurs in the tirst two
species only. The clypeus of the male i.s usually truncate and that of
the female acute, or at least more so than the male. The only constant
and invariable character is found in the pygidium. This organ in the
male is always regularly convex, in the female broadly transversely
impressed aiid much smoother in tlje impressed space than the corre-
sponding portion in the other sex. The anterior spur of the u)iddle
and hind tibiae is sometimes stouter in the male than the female,
although the difference is neither very obvious nor important.

S. .llltae^US Fab., Maimon Fab.

General characters. — Form broadly oval, piceous or dark castaneous,
shining. Elytra with sutural stria visible only at apex. Outer angle
of the tip of the middle and hind tibite simply emarginate and with
unecjual spinules.

Male. — Thorax with three horns, one from the middle of the an-
terior margin of the thorax, directed forward and upward, and one
from each side behind the middle directed inward and slightly back-
ward, of more robust form than the anterior horn. A moderately
deep fossa on each side between the bases of the anterior
md middle horns. Clypeus oval, subtruncate at tip, front
with two slight tubercles. Galea of mandibles tridentate,
inner and outer teeth very feeble, middle tooth long slender
md subacute.

Female. — Thorax with an obtuse tooth at middle of an-
terior margin, behind which is a moderately deep fossa of
somewhat crescentic form, transversely wrinkled. Clypeus
similar in form to that of the male. Galea of mandibles
tridentate, inner two teeth similar and equal, outer broader and less
prominent.

This species may be distinguished from all the others by the absence
of the sutural stria. I have, however, seen one specimen in the cabinet
of Mr Ulke with a very faint stria. The thoracic processes of the male
become at times very short.

Occurs from New Jersey to Texas.

S. .IllIiHIlUM Hurin.

Gi'ueral characters. — Form oblong oval, piceous or castaneous, thorax
and head always darker than the elytra. Sutural stria entire
and moderately deep. Outer angle of the tip of the posterior
LJbiye distinctly tridentate and with one or two spinules unly
on each side of the middle tooth.

AMERICAN COLEOPTERA. 145

Male. — Thorax with a moderate horn from the middle of the an-
terior margin, and one on each side broad and laminiform obliquely
truncate or rounded at tip and crenulate ; a deep fossa on each side
as in Antseus. Clypeus broadly emarginate and slightly re-
flexed at tip, front bituberculate. Galea of mandibles lamini-
form, truncate in front with a slight notch and a slight sinu-
ation externally.

Female.— IhoxsiX with slight tubercle at middle of ante-
rior margin with an antemedian, oval, moderately deep fossa.
Clypeus oval and truncate at tip Galea of mandibles re-
sembling that of the male with, the outer tooth in form of an obtuse
lobe.

In both sexes the thoracic fossae, as well as a narrow space alon"-
the basal margin, are transversely wrinkled. The thoracic processes
of the male become greatly reduced in many specimens so that the
form of the female is approached, but however much the posterior
horns are reduced, the anterior is always moderately prominent and
more so than in any female. The form of the thorax resembles the
preceding species in having the sides very strongly arcuate at middle
and rapidly narrowing at apical half.

This species occurs from Georgia to Mexico.

S. splendens Beauv.

General characters. — Form oval, narrower in front, color uniform,

castaneous. Elytra with distinct sutural stria. Outer angle

of the tip of hind tibia deeply notched, with very slight trace

of tooth in the notch and two spinules only.

Male. — Thorax with a short process from the middle of the anterior

margin, very broad at base, behind which is a shallow oval impression.

Clypeus truncate at tip and feebly reflexed, front with feeble tubercles.

Galea of mandibles with the middle tooth prominent but

broad and obtuse at tip, inner tooth very short, outer scarcely

evident. Anterior spur of middle tibia conspicuously stouter

and broader than in the female.

Female.— Thorax with feeble trace of tubercle near the
anterior margin and a very shallow impression. Clypeus
less distinctly truncate at tip. Galea of mandibles with
the inner two teeth similar and equal, outer in the form of a slight
lobe.

^ This species is a little less robust than Antxus and narrower ante-
riorly. The only difficulty which might arise with the present species
is in the separation of its males from the females of the preceding.

146 GEO. H. HORN, M. D.

Here reliance must be placed primarily in the form of the galea of
the mandible and secondarily in the form of thorax. The bead along
the basal margin of the thorax is here very feebly and in Jidianus
very well developed.

This species occurs in Georgia and Florida, and is not common.

S. IVIorinoii Burm.

General characters. — Body oval, slightly narrower in front, color
castaneous. Sutural stria entire, deep. Hind tibiae as in Avtxiis.
Male. — Thorax with a very small tubercle notched at summit, and
a vague and very slight impression. Clypeus oval, tip re-
flexed and subacute, front not tuberculate. Galea of mandi-
liles with the middle tooth prolonged into a slender and
acute process, inner tooth obtuse and inconspicuous, outer
entirely absent.

Female. — Thorax similar to the male. Clypeus very acute
at tip. Galea of mandibles similarly formed but with the
median tooth less prolonged.

In the prolongation of the middle tooth this species resembles the
male of Antaeus, its characters are so evident that it will not be mis-
taken for that or any other species.

Occurs in Kansas and Texas, very rare.

S. cessu.«» Lee.

General characters. — Form oblong oval, slightly narrowed in front,
color uniformly piceous. Sutural stria entire, elytra with more de-
cided evidences of sculpture. Hind tibiae as in Antseas.

Male. — Thorax with a feeble tubercle near the margin,
behind which is a shallow oval impression. Clypeus oval,
tip subtruncate and reflexed in an obtuse point. Front with
feeble transverse ridge. Galea of mandibles not notched,
truncate in front free angle rounded.

Female — Precisely similar to the male in every respect

except in the form of the pygidium as already explained.

This species cannot be confounded with any other. The similarity

of the males and females is what might be expected to occur. The

sexes are barely distinguishable in splendens. less so in Mormon, and

identical here.

Occurs in Arizona, rare.

One species of this genus remains as yet unsatisfactorily determined,
Scar<ibseus Bosci Beauv., Ins. p. 89, pi. 2b, fig. 1. It is evidently of
the size and form of splendens and has a similar horn at the anterior
thoracic margin, but the clypeus is described as being very acute, in

AMERICAN COLEOPTERA. 147

this respect resembling Mormon. I do not know that the latter species
has ever occurred in the Carolinas, and suspect that the form of the
clypeus is erroneously described, and if so, the synonymy is with
splendens.

obtuse at tip. Thorax slightly broader than long, cylindrical, sides slightly
arcuate in front, feebly sinuate at basal half which is sub-acutely margined,
hind angles sub-acute posteriorly; apex truncate, base feebly bisinuate and

densely punctured. Scutellum semicircular, nearly smooth. Elytra subcylin-
drical, parallel, gradually narrowed at apical third, margin near apex finely
serrate, apex obtuse, surface densely punctured and with traces of striiB at the
sides and apex. Body beneath coarsely but not densely punctured and with a
few short cinereous hairs. Posterior tarsi with the first joint feebly compressed
and not greatly longer than the second. Length .36— .48 inch ; 9 — 12 mm.

Occurs in the San Joaquin Valley, California. I have seen very
many specimens in the museum of the Jardin des Plantes, Paris.

This species has the form of a small Latipalpis. The ridges above
the antennae are much shorter than in any of our other species, and
the antennal cavities approach the form seen in Psiloptera . The tarsi
have shown already considerable variation from the very long first joint
of the hinder tarsi in three of the species to that in which the first
joint is barely longer than the second (^cselatus) by which another
approach is made to the Psllopterides. Traces of a false joint at the
end of the eleventh occur in the antennae excepting in californicus and
sphenicus in which the eleventh joint is simply obtuse as in Psiloptera.
In Latipalpis the last joint is abruptly truncate and the antennae
appear to have lost a joint by fracture. No very decided sexual difi'er-
ences occur in the three genera above named.

CHALCOPHORA, Sol.
C Fulleri, n. sp. — Form oblong, depressed, color dark bronze feebly
shining and sparsely pubescent in patches. Head coarsely punctured, deeply
longitudinally grooved. Thorax broader than long, sides obtusely angulate at
middle, in front oblique, behind subparallel, feebly sinuate in front of hind
angles which are moderately prominent, apex feebly emarginate, base bisinuate,
disc with broad vague channel at middle and a moderately deep longitudinal
impression on each side, surface coarsely rugulose at the sides, smoother at
middle. Elytra oblong, depressed, parallel, apical third gradually narrowed
and moderately serrate, apex obtuse, surface with four vague nervures with
thickened spaces which surround large but very vague fovea; nervures feebly
shining intervals opaque, rugulose sparsely punctured and with very short

]>ubescence. Body beneath similar in color to the upper surface, irregularly
coarsely punctured, with spots of denser and finer punctuation. Length 1.10
inch ; 2S mm.

Male. — Fifth ventral segment triangularly emarginate, sixth with large,
oval, densely punctured and pubescent space surrounded by a slight elevated
margin.

Female. — Fifth ventral with an oval densely punctured and pubescent cuprous
space near the tip.

Two specimens are before me both of which are from Mr. A. S.
Fuller, to whom I take great pleasure in dedicating the species as an
evidence of my appreciation of his many acts of scientific liberality.
This species belongs to the same section of the genus as campestris and
Langeri but differs abundantly in the form of the thorax.

Occurs in Texas.

BUPRESTIJii, Linn.
B. (Ancylochira) connexa, n. sp. — Form elongate oval, subdeprcssed.
Head moderately densely punctured, color brilliant green changing to cupreous.
Thorax broader than long narrower in front, sides very feebly arcuate, disc
moderately convex with rather coarse punctures more densely placed at the
sides, color brilliant cupreous. Elytra wider at base than the thorax, oblong
oval, apex feebly attenuate, tip feebly emarginate, sutural angle acute, slightly
prolonged, disc striate, intervals equal, moderately convex and sparsely punc-
tured, color variable, brilliant blue along the suture shading to green with the
margin cupreous. Body beneath coarsely punctured, very densely at the sides
of metasternum and abdomen, color brilliant cupreous with green reflection.
Presternum and first ventral segment not sulcata. Length .60 inch; 15 mm.

This species belongs to that group in which the thorax is not sulcate
with Gibbxii, conjiupus, etc. Its form is that of Nattali while the
elytral sculpture and color more nearly resemble adjecta.

Two specimens 9 from Oregon and Owens' Valley, have the fifth
ventral segment slightly truncate at tip, and vary in the color of the
elytra. One is as above described, the other has the elytra brilliant
green with the margin cupreous near the tip.

Actenodes calcarata Chev., has occurred in Texas.

ELATERID.E.

Meriithus texanus Horn, is scobinula Cand.

Coryvihites prseses Horn, is Drasterius prseses Cand. This species
appears to be merely a poorly developed form of C. conjungens liCC.

Monocrepidias vespertinus Fab., and texanus Cand., may be sexes of
the same species.

Agriotes inversus Cand., is a Sericosomus, very T^vohahlj Jlavipennis
Motsch.

Limonius nitidicollis Lee, is consimilis Walker. This is probably

AMERICAN COLEOPTERA. 149

the only species remaining valid of all those described by Walker in
" Naturalist in British Columbia."

Aaaphes verna % Gand., is morio $ Lee.
Asaphes coracinus Cand., is carbonatus Leo.

The characters given by Candeze for the separation of these species
appear to be those of a sexual nature. An examination of large series
of Asaj^hes has shown that the females have the striae near the suture
very feeble or almost entirely obliterated, while in the males the striae
are normal. This character with the narrower thorax of the % and
the wider thorax of the female show the identity of the species above
cited. Other synonyms on the same basis remain to be determined
among the species of Asaphes but these must remain for a general
revision.

EUCNEMID^E.
Entomophthnlmus pallens Bonv., is rvfiolus (Lee.)
Ti'itjonopleurus rugulosus Bonv., is from Victoria, N. S. W., and not
United States.

Schizophilus trilohatus Bonv., and Nematodes simplex Lee, are
Schiz. subrufus (Rand.)

CLERIDJS.
In the Review and Magazine of Zoology published at Paris, appears
a paper entitled " Catalogue des derides de la Collection de M. A.
Chevrolat," and which evidently bears date subsequent to Sept., 1874,
in which are described various North American species as new. With
the assistance of Dr. Leconte, the descriptions have been compared
with specimens as they stand in our cabinets with the following
results :

Thanasimus m^lanocephalus Chev., is certainly a variety of nubilus
Kirby.

Ht/dnocera fnnebris Chev., is B. scabra Lee.

Pelonium pensylvanicum Chev., is probably a variety of Orthopleura
damicornis with oblique band behind the middle of the elytra.

Pelonium militare Chev., is Enoplium humerale Horn, Trans. Am.
Ent. Soc, 1868, p. 135.

Pelonium lineatocolle and /iliolus Chev., appear to be the same thing,
the former is undoubtedly Lebasiella maculicollis Lee, Trans. Am.
Ent. Soc, 1874, p. 63.

LYMEXYLIDJS.
Hj/lecoefus americanus $ Harris, is identical with lugubris Say.

150 GEO. H. HORN, M. D.

CERAMBYCIDiE.

Pnrawh'a Sai/i, qnadn'collis, con/ormis, dentatn and mimifa, Thoin*
son, are all merely slight variations of hniunca Fab.

P. po/ita Say., occurs also in Mexico, wheace it has been described
by Chevrolat under the name cyUmlricn.

It may be well to mention here that two forms occur in Parandra,
first, the long, slender, shining and depressed form, and secondly, the
shorter, more robust, less shining and more convex. The former with
distinct onychium and paronychia, and the latter with both so retracted
as to be almost invisible. ]My attention was directed to the apparent
absence of onychium in our common species by Mr. II. W. Bates, and
subsequent examination has shown that the form of body is also an
indication of the development of the onychium in any of the species.

Pilcma Lee, is thought by Mr. H. W. Bates, to be identical with
Callimus Muls. The form of the one certainly resembles very greatly
the other, but having no specimen of Callimus with which to compare
Pilcmci, the latter name must be allowed to stand, inasmuch as the
best three European descriptions vary so greatly as to leave the matter
in great uncertainty.

Callimus chalybsens Lee, is however not a Callimus.

(Jtytus nitidtts Horn, is omitted from the Check List on suspicion
that it might be C. magicus. This however is not the case, nitidus is
a Xylotrcchus and magicus a Neoclytus. I was moreover unable to find
any species in Europe at all resembling it. The name must therefore
be restored to the List.

Plngi/thmysua pulveridentus Motsch., is distinct from any species I
have seen and appears- to be a Neoclytusj and if so the generic name
of Motschulsky has priority.

Amphidesmus xanthomelas Guerin. Specimens in the Jardin des
Plantes from Lower California.

Monohammus minor Lee, is probably identical with carolinensis
Oliv., and is doubtfully valid as a species.

Eutessus anper Lee, is Mev.otetartus antennatus Bates. This species
occurs from Lower California to Yucatan.

PogoHocherus sordidits Lee, is an Eslola Fairm.

AMFIIIOXYCIIA, Lee.
The first appearance of this name is in the catalogue of the collec-
tion of Dejean. Ilaldeman quotes the name from that author without
however giving any description, (Trans. Am. Phil, Soe, 1847, p. 57),
redescribing A. marginata Fab The name next appears in " An
attempt to classify the Lougicoru Coleoptera of the part of America

AMERICAN COLEOPTERA. 151

north of Mexico," by J. L. Leconte, M. D., Journ. Acad., 1852, p. 154,
where the genus is for the first time fully described, and A. (Saperda)
ffammata Newm., the only known species described. Subsequently
Mr. James Thomson (Archiv. Entom. I., p. 311), describes anew the
genus giving a totally diflFerent type, A. luctuosa Lesel. from Brazil.
Lacordaire (Genera IX., p. 890), adopts Thomson's description and
type entirely ignoring any reference to Leconte. It appears that the
genus was first described by Leconte with ^amwa^a as the type and
the genus as described by Thomson and Lacordaire is an entirely
different matter, and should receive another name. I would suggest
that the name Oedudes, subsequently given by Thomson, be adopted.

CHRYSOIMELID^.
Megistops quadrinofata Boh. Eugen. Resa, is quoted from California.
The other species are from Chili and Venezuela, and it is probable that
this one is also.

BRUCHID.E.
Bruchus impiger Horn, is identical with ramicorms Boh.

TENEBRIONID^.

Scotobsenus Lee. My attention was called by M. Aug. Salle, to the
probable synonymy of this genus with Centronopus Sol., of which the
type is suppressus Say., from Mexico. While examining the admirable
collection of Heteromera of Mr. Fred. Bates, I was enabled to satisfy
myself of the fact of the identity of the two, and would suggest the
name Scotohates for the species now known as Centronopus \.

Eutomus (Dej.) Lac. There appears to be no doubt that this genus
is very closely allied to if not identical with Rhipidandrus Lee. Chapuis
has already stated that Eutomus is a Tenebrionide. Future investiga-
tion will, I think, show that neither belongs to the Tenebrionidae.

MONOMMID^.
Hyporhagus Lecontei Thorns. Examined the type of this species
and the type of laevipunctatus Thoms., in the cabinet of Count
Mnizech, and find them identical, the former being the male. The
species is from the United States of Columbia and not California.

OTHNIID^.
In the Rev. et. Mag. Zool , 1874, M. Aug. Chevrolat describes
Othnius mexicanus as new. This species was described by myself
under the same name in the Trans. Am. Ent. Soc, 1868, p. 133.

MELOIDiE.

Several of our not uncomraon Western species have been rede-
scribed by Du^es, in the Transactions of the Natural History Society
of Mexico. The synonymy has been determined and placed in the
hands of M. Salle of Paris, as belonging more properly to those dealing
■with the fauna of Mexico.

CORDYI.OSPASTA, n. g. (Mefoidoe.)
Body winged, metasternuui moderately long, middle coxae not cover-
ing the posterior. Elytra entire covering the abdomen but not con-
cealing the metasternal parapleurse. Antennae eight-jointed, clavate
not as long as the head and thorax, slightly arcuate; first joint moder-
ately stout but short, second very short, third as long as the fir.st, fourth
to seventh gradually shorter and broader, eighth longer than the pre-
ceding three, cylindrical, obtusely pointed at tip. Tibiae slender, each
with a single, sleoder, moderately long spur. Tarsal claws cleft, the
two portions connate, the lower portion half the length of the upper
and its tip forming a slender acute tooth at the middle of the upper.
Anterior femora without sericeous spot.

The form of the antennae of this genus appears to be unique in the
family. The terminal joint shows a slight tendency to segmentation
at its base so that the antennae might possibly be thought to be nine-
jointed. This genus is certainly the nearest approach to the Mylahrini
our country has yet produced and it appears to differ from that tribe
only in the form of the tarsal claws and the unique tibial spurs. By
these characters I would suggest its pasition in a group intermediate
between the Mi/lahrini and Lt/ttini.

C Fuller!, n. sp. — Black, subopaque. Head subquadrate, narrower in front,
occiput truncate, hind angles rounded, surface opaque (minutely granulate)
sparsely punctured. Thorax transverse, not wider than the head, nearly twice
as wide as long, apex suddenly narrowed, sides feebly arcuate, base slightly
emarginate at middle, margin slightly retlexed, surface sculptured as the head.
Elytra nearly twice as wide as thorax and twice as long as head and thorax
combined, parallel, each rounded at tip, surface opaque, scabro-reticulate. Scu-
tellum oval at tip. Body beneath black, shining. Legs slender, moderately
long, black, moderately shining.

Male. — Fifth ventral segment moderately long, nearly semicircularly emar-
ginate, angles acute, pronuuent and moderately divergent. Length .22 inch;
5.5 mm.

I take great pleasure in dedicating the species to Mr. Andrew
S. Fuller, as a slight evidence of jny appreciation of his many
kindnesses.

One specimen Nevada, from Mr. A. S. Fuller.

AMERICAN COLEOPTERA. 153

EPICAUTA, Fab.
E. Batesii, n. sp. — Moderately robust. Color of body and legs ferruginous,
moderately densely covered above with concolorous pubescence which is on the
under surface cinereous. Antennae piceous, paler at base, filiform, joints closely
approximated. Eyes moderately large and convex, rather coarsely granulated,
scarcely emarginate. Head moderately densely punctured. Thorax subquad-
rate, as wide as long, median line distinct, surface moderately densely punc-
tured. Elytra punctured similar to the thorax moderately densely covered
with pubescence of a color similar to that of the surface, slightly paler along
the suture. Body beneath darker ferruginous, the abdominal segments piceous
along their hinder margins, surface somewhat more coarsely punctured than
above and densely clothed with cinereous pubescence longer than that of the
upper surface. Legs paler ferruginous. Length .36 inch; 9 mm.

This species by the form of the anteunae and eyes takes a place in
group A in the revision of the genus published by me, Proc. Am.
Philos. Soc, 1873, p. 95. It is rather more robust than any of the
allied forms although resembling ferruginea and strigosa. It diffei's
from all the species at present known in the group by its pale ferrugi-
nous legs. In the Florida specimens the body beneath is nearly
piceous and the head darker than the thorax. No special sexual
differences occur.

I take great pleasure in dedicating this species to my friend Fred.
Bates, of Leicester, England, whose contributions to our knowledge
of the Heteromera are so well and favorably known.

Savannah, Ga. and Florida. Two specimens given me by Mr. Bates,
from the Dejean collection, bore the name lurida.

Meloe trichrus Pallas, Icones Ins. 100, tab. E, fig. 32. This is that
variety of Epicauta convolvuli Mels. (Proc. Acad. 3, 53.) in which the
pubescence is gray and the head red. The former specific name has
many years priority and should be restored.

E. oregona, n. sp.— Black, subopaque, cinereo-pubescent. elytra with
numerous denuded small spots. Head sparsely punctured, subopaque, with a
smoother spot within and above the insertion of each antenna. Antennse as
long as half the body, moderately strongly flattened, gradually more slender
to the tip. Thorax quadrate, narrower than the head, sides at anterior fourth
arcuate and narrowing to tip, posterior three-fourths parallel, surface subopaque,
sparsely and finely punctured. Elytra slightly wider behind, sparsely punc-
tured, sparsely cinereo-pubescent with numerous small, denuded, rounded spots.
Body beneath and legs more shining than above, sparsely punctured and pu-
bescent. Length .36 — .40 inch ; 9 — 10 mm.

Male. — Antennae more distinctly flattened; anterior tibiae with two spurs;
fifth abdominal segment feebly emarginate.

This species should be placed next to cinerea in the table given by

me (Proc. Am. Phil. Soc, 1873, p. 96,) of the species of this genus.

It differs from that in the maculate surface and the spurs of the hind

154 GEO. H. HORN, M. D.

tibicG slender and acute while in cinerea the spurs are both stout and
very obliquely truncate at tip. Superficially oregnna j^reatly resembles
some of the forms of maculata, but the male sexual characters at once
suffice to separate it.

Several specimens collected in Oregon, by Mr. Wm. M. Gabb.

E. Alphonsii Horn, Trans. Am. Ent, Soc, 1874, p. 38, should be
placed near maura Lee, the middle femora beinii similarly dilated in
the male, a specimen of which was kindly given me by the late Jules
Thevenet. It differs from maura in having the suture and margin
narrowly bordered with white pubescence.

GNATHOSPASTA, n. g.

Antennae setaceous, eleven-jointed, first joint moderate with a slight
sinuation in front near the tip, second joint short, half
the length of the third, these two together but little
longer than the first, joints 4 — 11 gradually longer.
Eyes elongate oval, twice as wide as long, emarginate
in front. Labrum very deeply emarginate, mandibles
prominent, pincer like. Labial palpi rather slender.
Other characters as in Epicauta.

The mandibles are very much more prominent than in any vesicant
in our fauna; they meet at tip and are directly opposed along a straight
line and not emarginate, behind which they are slightly separated, the
inner margins being feebly sinuous. The form of labrum and mandi-
bles preeminently distinguishes the genus.

I have seen in the cabinet of the British Museum several species
of very large size from China and the East Indies with this form of
mandible which should probably be placed in this genus. I might
here mention another curious form in the same Museum, allied to
Fi/rota but the labrum is long, rhomboidal, truncate in front, con-
cealing the parts of the mouth beneath; mandibles stout, directly
opposed, margin crenulate and with the outer face grooved. The
antennae are strongly flattened in the male and resemble those of
certain Elateridae.

The form of the first antennal joint of G nathospasta points to an
affinity with Macrohasis.

a. mimetica, n. sp. — Elongate, black, moderately densely clothed with
rather coarse, recumbent, cinereous hairs. Antennae black. Head ratiier large
coarsely and moderately densely punctured. Thorax smaller than the head,
sides at apical third rapidly converging, posteriorly gradually narrowing to
base, median line feeble, disc moderately densely and coarsely punctured.
Elytra at base scarcely wider than the head, gradually broader posteriorly,

AMERICAN COLEOPTERA. 155

surface moderately densely punctulate. Body beneath and legs, moderately
densely p\inctured and cinereo-pubescent. Length .44 inch; 11 mm.
Male. — Sixth ventral segment slightly emarginate. Metasternum concave.
One specimen, Texas. (Belfrage, No. 609). Resembles so much
certain of the unicolored forms of cinerea as to be with difficulty dis-
tinguished except by the generic characters.

CANTHARIS, Linn.

C {Lytta) mutilata, n. sp. — Body black, head and thorax red. Head with
very few punctures, epistoma and parts of mouth black. Thorax subpentagonal
very little wider than the head, a very fine median line, surface very sparsely
punctured. Elytra black, rather finely scabro-punctate, smoother near the base.
Body beneath black, moderately shining, sparsely punctate. Legs black more
densely punctate. Length .86 inch; 22 ram.

Male. — Antennae with fifth joint deformed, excavate anteriorly and with the
anterior angle slightly prolonged, sixth joint slightly flattened, 7 — 10 oval, 11
slightly longer and pointed. Anterior tibise with two spurs, hind tibiae with
inner spur slender acute, outer longer, cylindrical and obliquely truncate at tip.
Last dorsal segment oval ai tip, fifth ventral truncate, sixth very feebly emar-
ginate. Hind trochanters simple.

Female. — Unknown.

This species should be placed next to eucera in my revision of the
species of this genus.

For the privilege of studying a perfect male, I am indebted to Mr.
Otto Lugger of St. Louis.

Occurs in Arizona.

ZONITIS, Fabr.

Our species are distinguished as follows :

Eyes lateral, not extending beneath the head ; antennae at most half the length
of the body.
Legs bicolored.

Elytra black, head and thorax yellow atripennis Say.

Body above pale yellow, elytra tipped with black Ilavida Lee.

Body above pale yellow, elytra with piceous vitta bilineata Say.

Legs piceous.

Body above and beneath pale sanguineous rufa Lee.

Eyes large, extending beneath the head, and comparatively approximated;
antennae setaceous, nearly as long as the entire body.

Thorax and elytra very densely punctured longicornis Horn.

Thorax and elytra very sparsely punctured vittipeniiis n. sp.

Z. bilineata may become unicolored, pale yellow, but the elytra are
always coarsely punctured.

Z. Tittipennis, n. sp. — Form elongate, pale yellowish testaceous, moder-
ately shining. Antennae nearly as long as the entire body, setaceous, piceous.
Head oval deeply but sparsely punctured. Eyes large, coarsely granulated,
extending beneath the head. Thorax subcampanulate, not wider than long,
disc shining, sparsely and irregularly punctured. Elytra pale yellow, with two

156 GEO. H. HORN, M. D.

piceous vittsE on each, one near the suture, the other broader near the side
margin, ncitiier attaining the tip or base, surface with coarse shallow punctures
becoming more indi^itinct at base. Body beneath colored as above, shining,
sparsely punctured ; abdomen densely punctured. Femora yellow tipped with
piceous, tibiffi piceous yellow at base, tarsi piceous. Length .40 inch ; 10 mm.

The body above is sparsely clothed with short, yellowish incon-
spicuous hairs, those of the uuder surface are somewhat longer and
denser.

One male, Arizona.

This species and longicornk may vary in the extent of the piceous
elytral vittas. The type of the latter was described as having brown-
ish-testaceous elytra, with suture, margin and narrow median stripe
paler, but specimens have occurred marked similarly to vittipennis,
that is, with the paler color predominating.

CTSTELID.E.

CISTEL,.!, Fab.
C\ Theveiictii, n. sp. — Piceous. subopaque, form elongate. Head piceous,
rufous in front, minutely and densely punctulate. Antennae subserrate, nearly
as long as the entire body, piceous, three basal joints rufous, joints two and
three short, together but little longer than half the fourth. 'Thorax piceous,
minutely and densely punctulate, broader than long, sides regularly arcuate and
gradually narrowing to apex. Elytra not wider than the thorax and nearly four
times as long, black, striate striae finely punctured, intervals slightly convex,
sparsely and very minutely pubescent. Body beneath piceous, more shining
than above, sparsely punctulate. Legs pale rufous, tibiae and tarsi somewhat
darker. Length ..>0 inch ; 7.5 mm.

This species belongs to the same group of the genus with opaca and
is easily known by its slender form and red legs.

One specimen Mariposa, Cal., from M. Jules Thevenet.

C. TariabiliK, n. sp. — Form oval, color variable. Head densely punctured.
Antennae half the length of body, slender, second joint half as long as third,
the latter as long as the fourth. Thorax broader than long, gradually narrow-
ing to apex, surface more densely punctulate than the head, very sparsely
pubescent. Elytra oblong oval, minutely punctulate, more shining than the
thorax, and with feeble traces of the two inner striae only, surface sparsely
cinereo-pubescent. Prosternum beneath rugulose, metasternum smooth at
middle, sides sparsely punctured, abdomen shining, sparsely punctulate.
Length .20 inch ; 5 mm.

Somewhat broader than sericea which it otherwise resembles.
Varieties in color occur as follows :

a. — typical, black, thorax red, beneath and legs piceous, the latter some-
times red.
b. — entirely piceous, varying with paler legs and elytra.
c. — entirely testaceous, as in sericea.

Occurs rather abundantly all over California.

Notes on CICINDEIilDiE of the United States.

BY JOHN L. LECONTE, M. D.

OMUS Eseh,
O. Hornii. — Robust, dull black, witb a slight silky lustre, head with a few
indistinct rugae between the eyes. Prothorax little wider thaa long, subquad-
rate, less narrowed behind than in any other species, and less convex; hind
angles rounded, disc slightly rugose at base and tip, transverse impressions dis-
tinct but not deep, dorsal line fine. Elytra rather broadly ovate, wider than
the prothorax, much rounded on the sides, deeply punctured, with a few larger
but not conspicuous punctures intermixed. Legs rather slender, about as in
O. Audouini. Length 16.5 mm.; .65 inch.

One lemale collected by Mr. Joseph Willcox at Yosemite in Cali-
fornia. A remarkable species, eminently distinct by its broader form,
more quadrate prothorax and diflFerent sculpture.

€ICINDEL,A Linn.

C. longilabris Sa?/.

I have mentioned in another place a beautiful green specimen from
Newfoundland, 'given me by Mr. Chevrolat; I wish now to call atten-
tion to a variety found in Oregon and Utah, which is either bluish
green, bronze, or black, but diifers from the ordinary Canadian race
of this species by less opaque surface, and more deeply punctured
elytra.

Dr. S. Lewis has given me a specimen from the mountains near
Denver, Colorado, of a fine bronze color, but more elongate and more
convex in form, in which the white markings are broader and more
conspicuous ; the humeral and apical lunules are entire, and the medial
band is connected along the margin with the humeral lunule.

C. montana Lee, Proc. Acad. 1861, 338, is to be suppressed as a
species, and must be considered as a race allied to the one above
mentioned, with the elytra less elongate and more convex than usual.
The labrum of the $ is dark, but I have observed a tendency to the
same peculiarity in other instances, and am not disposed to regard it
of specific value.

C. scutellaris Say.

Specimens occur in Texas of a blue-green color, resembling closely
in appearance the race uuicolur which occurs in Georgia and Florida,
but having the prothorax finely rugose, as in the typical scutellaris with
copper colored elytra. Baron Chaudoir is quite correct in considering
rugifrons, Lecontei. unicolor and scutellaris^ as races of one species,
differing greatly in color, and to a less extent in form and sculpture,

158 J. L. LECONTE, M. D.

but both he and Crotch, who has followed him in the "Check List,"
have omitted to observe that in this consolidation of names, Scutellaria
(1823), must take precedence over rwji/rons (1825).

€. 10-nof at a Say.

One % differs from the others in my collection by having the labial
palpi pale, with the last joint metallic. This species is very closely
allied to some of the races of C. splendida, but the prothorax is smaller
and more convex, and the medial band of the elytra runs much farther
backward. The form next mentioned is however nearly intermediate
in the latter respect.

a. — Two specimens from California, of a bright green color, marked
nearly as in lO-notata, but the humeral and post-humeral spots are
absent, and the medial band is a little shorter.

,3. — A male specimen from Nebraska, of a bright green color, the
spots much reduced in size, and the medial band represented only by
its outer part, which is perpendicular to the side margin of the elytra.
The labial palpi are pale, with the last joint dark.

C hyperborea Lcc, New Species, Smiths. Misc. Coll. 1.; var. C. limbata
11 Say, Journ. Acad. III., 139,

This long lost insect has been recently found by Mr. E. P. Austin
of the U. S. Coast Survey, on hills of white sand in Northern Nebraska,
and proves to be a form of the species, which in
its normal marking was described by me as C.
hi/perhorea ; I repeat here the two wood cuts
given by Dr. Horn (Proc. Ac. 1866, 397), and
add one of this extreme variety to show how
easily by a slight variation in breadth of mark-
ings a quite different appearance will result. The description of Say
relates solely to color, and therefore the identity of his species with
liypcrhorea could never have been suspected. In consequence of this
determination the name limbigtra proposed by Gemminger and Harold,
Cat. Col. 20, to replace the preoccupied name used by Say, becomes
unnecessary.

C Wapleri. — Elongate, slender, allied to C. cuprascens, with the elytra
equally coppery and deeply j)unctured; side margin broadly white;

a basal spot small, humeral lunule curved, not hooked behind; medial

AMERICAN COLEOPTERA. 159

One specimen from Mississippi, kindly sent me by Mr. A. Salle,
under the MS. name given by Baron Chaudoir. It is a smaller and
more graceful species than the one with which I have compared it, and
easily recognized by the elytral markings. The tooth of the labrum
is hardly apparent.

C 9Iagdalense Lee, Proc. Ac. Nat. Sc, Phila., 1873, 321.
Dr. Horn has kindly prepared a wood cut from the drawing which
he made from the specimen of this species in the Oxford Museum.

Bit was found with other North American species in barrels
of turpentine, supposed to be from North Carolina. The
markings as will be seen resemble those of cinctipennis, with
the addition of a basal spot and an elongate spot on the
suture, extending nearly to the middle. The prothorax is
finely rugose ; the dark parts of the elytra are distinctly
punctured, and the tips are finely serrate. These characters indicate
that it belongs in the group with blunda, macra, cuprascens, etc.

C neva<lica. — Coppery bronze, head moderately large, eyes less prominent
than in C. speraia, front sparsely hairy, finely striate near the eyes.
Prothorax nearly cylindrical, finely rugose, transverse impressions
deep, sides hairy. Elytra deeply but not coarsely punctured, marked
as in the adjoining figure, proportioned as in C. sperata, sutural spine
distinct. Legs long and slender, claws large, hind trochanters red.
Labrum transverse, nearly straight in front, not distinctly toothed
at the middle; palpi pale, last joint only dark. Length 11 mm.; .43
inch.

■J,. — Prothorax with the sides slightly rounded ; elytra obliquely and broadly
subsinuate near the tip.

5. — Prothorax with the sides straight, and the base somewhat flattened;
elytra obliquely and strongly sinuate near the tip; anterior angle of the sinua-
tiou obtuse and rounded.

Nevada, Mr. E. P. Austin. This species is allied to C. sperata^ but
difi"ers by the tooth of the labrum being obsolete; by the markings of
the elytra not connected at the side margin, and by the posterior part
of the humeral lunule less oblique, not hooked, and by the medial
band less prolonged behind. Finally the prothorax of the 9 is less
distinctly flattened near the base.

<\ politula. — Above black, somewhat shining, slightly tinged with blue
and bronze on the head and prothorax; beneath and legs blue, abdomen fer-
ruginous. Head striate near the eyes, front convex very finely striate. Pro-
thorax finely rugose, not longer than wide, transverse impressions deep, sides
broadly rounded. Elytra convex, oblong, finely and densely punctulate, tips
rounded, obsoletely serrate, sutural spine very small, terminal lunule repre-
sented by a narrow short white line, which is sometimes obsolete. Labrum
white irregularly rounded in front, tooth obsolete; labia! palpi pale, with the
last joint dark. Length 12 mm.; .476 inch.

Texas. This species has been long known under the name here
adopted, but I cannot find that it has been published. It is of the
size and general form of C. pnnctulata, but quite different in its cha-
racters, which ally it to C. abJominalis. The white hairs are sparse,
and visible only on the under surface ; the series of large punctures
usually seen on the elytra near the suture are not distinct, or barely
perceptible.

A singular race of this species was found by Messrs. Hubbard and
Schwartz, at Cedar Keys, Florida. The specimens diifer from those
found in Georgia and New Jersey, as well as from others collected in
Florida, by the elytra being quite strongly and deeply punctured; the
large punctures or foveae near the suture are also deeper. Otherwise I
can discover no difference, and am therefore unwilling to characterize
this peculiar form as a distinct species.

C, margiiiipeiinis Dej.

Mr. F. G. Schaupp has informed me that during the past summer
he collected this species at Calicoon, Sullivan Co., New York. The
only locality previously known is at Harrisburg, Penna. It will prob-
ably be found at various points in the upper valleys of the Susquehanna
and Delaware rivers.

C. striga. — Dark bronze, with a slight olivaceous tinge, shining. Head
large, scarcely concave between the eyes, which are large and prominent; a
few short lines are visible each side between the eyes. Prothorax not longer
than wide, convex, with a few distinct rugiB, especially near the tip and base,
front transverse impression deep, hinder one indistinct, dorsal line faint, sides
moderately rounded. Elytra elongate oval, humeri distinct, surface sparsely
but strongly punctured, subsutural foveae large and deep, tips rounded, not ser-
rate ; apical lunule narrpw, bent obliquely inwards and forwards at the anterior
extremity; medial band represented by a submarginal whitish spot. Body be-
neath thinly clothed with white hairs. Labrum transverse, truncate in front,
and subsiuuate each side; maxillary and labial palpi pale, with the last joint
dark. Length 13.5— 16.5 mm. ; .53— .65 inch.

^. — Labrum white, nearly rectilinearly truncate in front, medial tooth
obsolete.

5 . — Labrum brown, truncate and subsinuate in front, medial tooth large
and acute.

Lake Harvey, Florida, May 4th, Messrs. Hubbard and Schwartz.
This species is allied to C. severa, but is quite different by the polished
surface, the deeper punctures of the elytra; the form of the labrum,
which is without a tooth in % , and only unidentate in 9 ; by the
maxillary palpi bt'iug al.-jo pale, with only the last joint dark; by the
head not concave between the eyes, and with fewer rugae near the

AMERICAN COLEOPTEBA. IGl

eyes, and by the posterior transverse impression of the prothorax
almost obliterated.

The habits of this insect are peculiar ; it was found only in the
twilight, or ni<j;ht, near the camp fires. The third joint of the
maxillary palpi is scarcely shorter than the fourth joint, agreeing in
this respect with G. severa.

C magH.— Sooty black, tinged with greenish, without lustre. Head with-
out striae, not concave between the eyes which are large and prominent. Pro-
thorax not longer than wide, moderately narrowed behind, sides rounded and
sinuate, transverse impressions well defined, dorsal line very fine, disc convex,
sparsely pubescent, not rugose. Elytra elongate oval, humeri not prominent,
tips not serrate, broadly and separately rounded, suture a little retracted in 9 >
but the spine is wanting in both sexes; sparsely and finely punctured, fovefe of
subsutural row well marked. Beneath opaque black, slightly pubescent, tibise
and tarsi brownish. Labrum with three distinct teeth, an I strongly sinuate
each side. Palpi pale with the last joint dark. Length 12 mm.; .5 inch.

Three specimens from Lake Ponchartrain have been kindly com-
municated by Mr. F. G. Schaupp.

This species is closely related to C. Pilntei but differs by much
narrower form, different color, stronger punctuation, and different apex
of the elytra, and by the prothorax being more narrowed behind, and
by the eyes being larger and prominent.

The labrum, as in C. Pilatei is black in the 9 j ^nd black with a
large white spot in the S .

Found in woods, near Lake Ponchartrain, Louisiana.

C. hirtilabris.— Slender, bronzed brown, body beneath, prothorax and
head clothed with fine prostrate white hair, labrum white clothed with similar
hair, with a small indistinct tooth at the middle. Elytra with a broad white
border, feebly dilated in the region of the humeral lunule, middle band broad,
marked with numerous dark points and lines, producing a ramose appf^araiice,
immediately behind which is a dilatation representing the apical lunule, there
is also a small basal spot; the dark spaces are strongly punctured and the sutu-
ral spine is obsolete. Palpi pale, with the last joint dark. Legs very long and
slender, hind trochanters dark red, claws large. Length 9.3 mm. ; .(32 inch.

%. — Elytra obliquely narrowed near the tip, then suddenly rounded and sub-
truncate, suture not retracted; ventral segments uniformly pubescent.

9. — Elytra obliquely sinuate near the tip, then suddenly rounded; suture
slightly retracted; anterior angle of the sinuosity obtuse not prominent; last
ventral segment glabrous.

Florida, Mr. F. G. Schaupp. Of the same form as C. gratiosa, but
with finer pubescence and less dilated white markings, though the basal
spot is frequently connected with the margin. It is remarkably dis-
tinct from all the other species known to me by the labrum being
clothed with fine prostrate white hair, like the head and prothorax.

In one specimen the posterior angle of the white dilatation represent-
ing the apical lunule is prolonged inwards, and slightly hooked.

It is found promiscuously with G. torluosa, punctu/afa, and both
varieties of alxfommalis, on small sandy paths through meadows, near
Hogarth's landing, and near Spring Cove. They were seen in July.
August and September; in July ahdominalis was abundant, and hirti-
Inbrls scarce ; but later, these proportions were reversed.

The position of this species is in the group with blanda, cuprascens,
etc., next to gratiosa.

Notes on the RHYKODID.C of the I'nited Slates.

BY JOHN L. LECONTE, M. D.

On comparing specimens of Rhysodes and Clinidium from the Paci6c
States with those from the Atlantic district, I have recently observed
some characters which induce me to regard them as specifically different.
In pursuing my investigation, I have found certain sexual peculiarities
which seem to have been overlooked, and which will probably render
necessary a new study of the specie:^ heretofore described, and a more
accurate definition of their characters.

These sexual differences are to be perceived in the anterior femora,
and in the hind tibiae; sometimes also in the middle tibiae. I have
endeavored to indicate the differences in the tibiae in the adjoined
wood cuts.

RHYKODES Dalman.
§. — Prothorax with three entire deep grooves; elytra striate, not
costate ; middle and hind tibiae with one terminal spur.

Atlantic States, New York to Georgia and westward to Missouri.
The prothorax is about one-half longer than wide, broadly rounded on
the sides, more rounded near the tip ; the furrows are very deep, and
the two outer ones are dilated behind; the disc is convex on the sides,

AMERICAN rOLEOPTERA. 1C3

and the side margin is not visible from above. The elytral striae are
composed of approximate punctures, and the inner
striae are somewhat impressed.

S . — The front thighs are armed with a very
distinct tooth ; the middle tibiae are produced in-
wards at tip into a small cusp, and the terminal spur is slightly curved ;
the hind tibiae are obliquely impressed on the inner face, and slightly
dilated at tip. terminal spur small, straight.

9 . — Front thighs not toothed; middle and hind tibiae not dilated
at tip.

I have excluded from the synonymy reference to the descriptions of
European specimens which have been considered identical by Erichson,
Chevrolat and other authorities, because the hind tibiae are described
by Erichson as being dilated in an almost hook-like form, which would
indicate a greater resemblance to the r ext species.

Should they prove on comparison to be different, then it will be
necessary for the European species to receive another name.

In case the name exarafus is considered as involved in too great
confusion, in consequence of its use first by Dalman, and second by
Serville for two different species, the name americamcs will have
priority over aratus which has been adopted by Gemminger and
Chevrolat. I have preferred to retain exaratus, for although it was
first applied by Dalman to another species, it appears that Fabricius
had previously described the latter as Cucuius sukafus.

2. R. Iiamatus. — Brown-black, shining, head rather obliquely narrowed
behind the eyes, which are subtruncate behind, and lateral. Protliorax more
than one-half longer than wide, with three very deep entire grooves; elevated
spaces sparsely but distinctly punctured. Elytral striae
deeper than in the preceding, and more coarsely punc-
tured. Length 5.5 — 7.5 mm.; .21 — .30 inch.

%. — Front thighs armed with a distinct tooth; apical
cusp of middle tibise longer, acute; hind tibiae broadly
dilated, more deeply grooved on the inner side, with the terminal dilatation
transverse, acute at the inner end ; apical spur small.

$ . — Front thighs not toothed, middle and hind tibise simple.

California, Mr. Behrens and Dr. Horn. Narrower than the pre-
ceding, with the prothorax longer, less suddenly rounded in front, and
somewhat less convex. The elevated spaces of the head and prothorax
are sparsely punctured, and the elytral striae are much deeper.

Atlantic States, not rare. I have no hesitation in placing these two
II iraes as synonyms. The form of the prothorax is quite characteristic,
obloiij; anil not oval. The differences in the descriptions are easily
accounted for by the fact that Newman described the elytra as having
six grooves, but did not observe that the interval between the two outer
ones was abbreviated in front, about one fourth from the base. Germar
on the contrary, regarding the costae as more conspicuous than the
intervening grooves, and omitting the sutural one, described the elytra
as four-costate, with the outer costa, (corresponding with the region
from the fourth to the sixth grooves of Newman), as double for a
part of its course. For the purpose therefore of distinguishing more
easily the present one from allied species I would offer the following
diagnosis.

C SCUlptile. — Head obliquely narrowed behind the eyes, base nearly
truncate; eyes narrow, confined to the upper surface of the head. Prothorax
nearly twice as long as wide, oblong, sides broadly rounded, base and ai)ex also
broadly rounded. Elytra with the costae narrower than the deep intervening
grooves, subtnarginal costa abbreviated in front at the anterior fourth or rarely
the fifth, and usually confluent with the next one at the
posterior fourth. Length 5.5 — 7.5 mm. ; .21 — .30 inch.

'J,. — Front thighs distinctly toothed; front tibiae rather
suddenly dilated on the inner side, above the oblique
groove: then sinuate; middle and hind tibiae subsinuate
on the inner side, produced inwards at tip into a sharp process. Prosternuin
with a broad stripe of velvety surface; ventral segments with spots of similar
velvety lustre.

9. — Front thighs not toothed; front tibiae with only the usual arrangft-
nient of hooks and teeth; middle and hind tibite simple, with two small
apiciil spurs.

Slight variations occur in the arrangement of the outer costae of the
e'ytra, which I have indicated in the diagnosis.

C calC'Jiraliiin. — Piceous, shining, elongate. Head obliquely narrowed
lichind the eyes, base subtruncate; eyes narrow, rather prominent, confined to
the upper surface of the head. Prothorax nearly twice as long as wide, regu-
larly elongate-oval, (not oblong); angles not apparent. ' Elytra with the costae
towards the base wider than the intervening furrows, submarginal costa and the
next entirely confluent, with only a line of punctures in-
dicating the separation. Length 7.5 mm. ; .30 inch.

'J,. — Front thighs not toothed; front tibiae very feebly
■ lilated on the inner side; middle and hind tibite with
a large pointed apical process cm the inner side, one-half
the length of the tibiae, apical spurs two, small straight; under surface without
velvety spots.

5. — Middle and hind tibiae simple.

AMERICAN COLEOPTERA. 165

Two specimens from Vancouver Island, kindly given me by the
Rev. A. Matthews, and one from Oregon by Mr. Ulke. The line of
punctures on the outer costa of the elytra is deeper in one than in the
other specimens, and indicates probably a variation in sculpture similar
to that observed in C. sculptile.

In regard to the affinities of this family, that they are very complex
has been recognized by all observers, but they have in the main agreed
that the nearest relationship is with the Cucujidae. The resemblance
in several important structural details with the Carabidae has been well
pointed out, especially by Pirichson, Ins. Deutschl., Ill, 298, and has
been exaggerated by Crotch to such an extent, that he has placed
Rhysodidae as a family of the series Adephaga.

There ure, however, two lines of resemblance which I have failed to
appreciate, though they have been indicated by excellent authority;
these are with the Longicorn series in Spondi/Us, Parandrn, etc. ; and
with Rhynchophora in certain Brenthidae ; it is true that the monili-
form antennae give a somewhat similar effect upon a first view, but
there is so little similarity in the structure of the antennal surface,
when minutely examined, that I can attach no importance to these
supposed relationships.

The great master in classification, Latreille, who first proposed the
genus Rlii/mdes^^ though he did not describe it, had a clearer recogni-
tion of the true affinities, when he associated it with Capes. This
approximation has not received the approval of other investigators,
though I hope to demonstrate its correctness. The error which has
heretofore obscured the perception of this affinity has been the incor-
rect placing of Ciipes in the Serricorn series near Ptinidae, with which
it has only the remote relationship which I will point out below.

The extraordinary Australian genus Omnia Newman, which the
describer could not refer to any family at that time established, was
recognized by him to have affinities with Rhysodes and Capes ; Erich-
son, followed by Lacordaire, referred it doubtfully to the Cucujidae, but
without having had the opportunity of examining it.

By the kindness of Mr. G. 0. Waterhouse of th-e British Museum,
I made a careful study of the type of 0. Stanleyt preserved in that
institution, and perceived very soon that it was closely allied to the
(hijtea serrata which I had described from Oregon; this observation is
published in the Proc. Acad. Nat. Sc. Phila., 1873, p. 334, No. 195.

On a closer study of the four species of Cupesidae found in the
United States, I was obliged to separate C. serrata as a distinct genus
rrlacma, (Trans. Am. Ent. Soc, 1874, p. 87). This insect from its

1<JG J. L. LECONTE, M. D.

larj^er size and stouter form enables the important characters of the
under surface to be studied with more ease than the other species.

Commencing then with the head, we find the following resemblances
between the CupcsidiC and the Rhysodidae:

1. In (Uiprs the eyes are almost smooth as in lihi/.inJes, though the
very small lenses may be perceived under the epidermis; in Friacmu
the eyes arc very finely granulate, but not smooth.

2. The lobed head of Citp^.t and the form especially of the hind part,
and its junction with the prothorax are all suggestive of Rh^soJes.

3. The prothoracic episterna are separate in Capes and Priacma,
though wider aad more distinct in the latter.

4. The front coxae are peculiarly small in both families.

It is also to be considered that in other characters these two families
in question differ very greatly. The front coxal cavities are entirely
enclosed in llhysodidae, while they are open behind and partially
formed by the mesosteruum in Cupesidse. The middle coxae are widely
separated in the former, quadrate and contiguous in the latter. The
hind coxje are widely distant in Rhysodidae; transverse, meeting on
the median line, and extending to the side of the body in Cupesidae.
The basal ventral segment of the abdomen is visible at the sides and
at the middle in Rhysodidae, while it is entire and uninterrupted in
Cupesidae.

We thus see that the two families diflFer from all other Coleoptera
in the characters which they possess in common ; while in those by
which they differ from each other, (many of which I have not men-
tioned), they agree with some other families or genera.

I think therefore that we are justified in regarding them as frag-
ments, widely separated it is true, of a series of Coleoptera existing
in former times, which was of an undifferentiated nature. This series
was the original stem, or contained the ancestry, if I may use the
realistic expressions of a modern school, of the several series which are
comprised in the now existing great complex of normal Coleoptera, with
the penultimate joint of the tarsi not anchylosed to the last joint. This
complex consists of the series Adephaga, Clavicornia, Lamellicornia
and Serricornia.

To attempt to intercalate such anomalous families as Rhysodidae and
Cupesidae among the families which properly constitute the four series
above mentioned, would be like finding a place for Archiropteri/x in
our classification of existing birds; Ctrntmlus, Lepldosteus and Ltpi-
ihsiren among normal fishes, or Prof. Marsh's Dinocerata among recent
mammals.

AMEBIC AN COLEOPTERA. 1G7

Looking at the two families from this point of view we see in
Khysodidae a prothoracie structure, with feet that are suggestive of
Carabidae {Cfivina, etc.) ; mouth rather peculiar, somewhat resembling
Catagenus, but more related to Omma and Prlacma ; coxal arrange-
ments similar to Cucujidae; ventral segments combining Adephagous
aad Clavicornious characters.

In Glinidium moreover a form of eye confined to the upper surface
of the head, which reminds us of Pseudomorphidae.

In Cupesidae. we observe varied forms of antennae; somewhat per-
foliate, {Omnia, Priaona); nearly filiform {Capes sp.), or feebly ser-
rate {Capes sp.); gular sutures, (which are constant in great series of
other Coleoptera) varying almost according to species; (Tr. Am. Ent.
Soc, 187 t, p 88). We also observe an arrangement of coxae, and
prothoracie side pieces unknown in the Serricorn series; the former
resembling nothing else, the latter feebly indicative of the higher de-
velopment of the Rhysodidae and Carabidje.

I have already suggested (Class. Coleopt. North Am. 279), similar
views concerning the relations of the Spondylidae, as a fragmentary
survival of ancient forms, with our existing Cerambycidae and other
families. After a careful study of Trictenotoma, I am disposed to see
in it also a survival of a series which in former ages represented the
objects that we now know as Tenebrionidae, with a strong resemblance
to Prion idae and Lucanidae, and perhaps a slight tendency towards
Cucujidae.

Without dilating upon the subject at the present time, I may
here observe that the immediate relations of Trictenotoma is with
the Heteromerous series, in which it forms a family distinguished
from Tenebrionidae by the front coxae being transverse and the coxal
cavities angulated externally and open behind. The tarsi which are
nearly similar to Epltragas, and the antennae which resemble in type
those of many Tenebrionidae, though differing in modification from
any tribe of that family, confirm this view. The sensitive surface is
confined to the last three joints, the ninth and tenth being triangular,
produced inwards, with the apical surface alone sensitive and velvety ;
the eleventh joint is oval, somewhat acute at tip, and covered entirely
with sensitive surface. These sensitive surfaces are subdivided into
two by a transverse line, well marked on the ninth and tenth, but
feeble on the eleventh. The other joints are entirely without sensitive
pores, but the eighth is thickened and elevated at the distal end ; the
first joint is as long as the three following and stouter. Now this
restriction of sensitive surface to the distal end of the outer joints

1G8 J. L. LECONTE, M. D.

of the antennae so far as I know occurs only in Tcnebrionidaj and
Lucauidoe, and the particular modification in form seen in Tn'rtcnotoina
does not occur in either of those families. The mouth does not re-
semble at all that of the CerambycidcB ; in the latter tl»c ligula is
attached at the end of the ntoutum, and the iutorveDing coriaceous
piece is quite apparent ; in Trictenotoma the meDtum is larger, feebly
emarginate. and the ligula is inserted behind it as is the case with
Lucannn. The insertion of the antennse, and the form of the side
of the head in front of the eyes is also similar to the Lucanidad. I
therefore regard the affinities as strong in that direction ; while the
relation to the Prionidae is one mostly of external resemblance. I may
also observe, that the mandibles of Trictenotoma are quite different
from those of Pn'ouus, et«., in having on the under surface a fringe
of long cilijc as in Lepturn. If therefore it has any affinity to
Cerambycidae, it is towards the whole family, and not specially to the
Prionidae subfamily.

The original and earliest ideal forms of Coleoptera, which combined
the characters of the Isomerous and Heteromerous normal Coleoptera
with the Rhynchophora. are unknown, and if they ever existed, have
probably become extinct in the measureless lapse of ages since they
flourished upon the earth.

The only indications we have of their possible existence, are the
resemblances in form of certain Anthribidae to Lamiidae; the Rhyncho-
phorous modifications of the prosternura in Nematidium and other
Colydiidae, as well as in Cossyphus; and the similar form of mentum
in the higher Tenebrionidae to that observed in some Otiorhynchidae.
'J'he affinity of Rhinomacer with Rhinosimns, etc., may also be men-
tioned. I do not regard any of these relations as very strong; and
many wide breaks have to be filled in our series before they can admit
of satisfactory demonstration.

Grreat Salt Lake, Utah ; one specimen kindly given me by Mr. Ulke,
Allied to D. paUipennis, but larger and more slender, with the sides
of the front more rounded, and the angles of the clypeus more promi-

also differs by the more elongate form, and by the striae of the elytra
effaced for a greater distance near the base. The head is not rugose,
and only very sparsely punctulate.

This is a very interesting addition to our fauna, carrying as it does,
the distribution of the paUipennis group into the closed basins of the
interior of the continent.

Prothorax scarcely longer than wide, quadrate, slightly narrowed behind, sides
subsinuate near the base; basal angles rectangular; dorsal line deep, trans-
verse impressions indistinct; basal impressions linear, distant, the inner one
about one-fourth the length of the prothorax, the outer one short, adjacent to
the angle; side margin narrow, broken by a few distant crenulations, base
sinuate, margined only near the angles. Elytra with dentiform humeral angles,
and well reflexed margin, basa^ marginal line deep; strife deep, distinctly yet

sparsely finely pubescent. Length 3.4 mm.; .1.3 inch.

Owen's Valley, California; Dr. Horn. Very different in specific
characters from Z. spinicollis, though apparently belonging to the
same genus.

Colastus ogavensis and yuccse, Crotch, Trans. Am. Ent. Soc, both
belong to Carpophllus ; the anal segment of the % is quite distinct;
the first is allied to discouleus, the second to melanopterus.

Dacne picea. — Oval elongate, convex, shining piceous, glabrous; head
and prothorax finely not densely punctured, sides of the latter nearly straight,
except towards the tip, where they are feebly rounded. Elytra more finely
punctured, punctures not arranged in rows; humeri rufo-piceous. Beneath
I)unctulate finely pubescent, antennae and legs ferruginous. Length .3 mm. ;
.12 inch.

One specimen, California. Quite distinct from our other two species
by the finer punctuation, which on the elytra is not arranged in rows,
by the absence of elytral spots, and by the sides of the prothorax
nearly straight, converging in front. The elytra are also compara-
tively longer. ,

Mr. Crotch was quite correct in restoring the name Dacne Latr.,
(179G), to this genus and suppressing Engis Pai/k., (1798J.

IIYPODACXE, n. g.

1 have established this new genus upon a small insect resembling in
form, mouth, sternum, coxae and legs Daoie, but differing by the tarsi
not hairy beneath, with the joints one to four shorter, closely united

AMERICAN rOLEOPTERA. 171

SO as to become difficult of detection ; and by the ninth joint of the
antennae closely united with the tenth forming an obtuse compressed
club; the eleventh is connate with the tenth, and not distinct.

H. puuotata. — Piceous shining, oval convex, not densely punctured,
mouth antennae and feet paler. Prothorax twice as wide as long, gradually
narrowed from the base forwards, slightly rounded on the sides, which are
finely margined. Elytra more deeply punctured, punctures hot arranged in
rows. Tibiae slightly dilated, as in Dacne. Length 2.4 mm. ; .09 inch.

Middle, Western and Southern States. Less elongate than Dacne^

'and more nearly resembling in outline a small Tritoma, {Ci/rtotriplax

Crotch). The prothorax is scarcely perceptibly margined at base,

which is broadly sinuate; the under surface is very sparsely punctu-

late. The eyes are coarsely granulated.

Triphylltis elongatus — Elongate, dark piceous, punctured and pubes-
cent. Head with the front concave, and a small occipital im[)ression. Pro-
thorax wider than long, sides rounded, strongly margined, subcrenulate, disc
■with two vague impressions, sometimes scarcely af)parent ; tip truncate, front
angles rounded, hind angles rectangular. Elytra about four times as long as
the prothorax, more strongly punctured, pale brown, usually darker towards
the sides. Beneath densely punctured, mouth, antennae and legs piceous.
Length 4 mm.j .16 inch.
Alaska to California.

Cyphoii robustus. — Brown, clothed with short suberect pubescence.
Prothorax twice as wide as the head, nearly three times wider than long, sides
and apex rounded into a semielliptical curve, base bisinuate, sides somewhat
reflexed, disc finely not densely punctulate. Elytra rather strongly punctured,
with an obsolete sutural stria and three very indistinct dorsal costse. Antennae
half as long as the body; second and third joints equal, united as long as the
fourth. Length 5 mm. ; .20 inch.

New York; one specimen kindly given me by Mr. Ulke. Larger
and more robust than the other species in our fauna, resembling in
form Helodes {Microcara) explariata, from which, however, it differs
in other characters, both generic and specific. In view of the faintly
marked elytral costse, 1 do not feel justified in considering this species
as Elodes obscura Guerin, which remains unknown to American
entomologists.

CyphoH murinus Dej., which was not seen by Guerin, as hr as
I can judge by a MS. drawing by my father, is Dicranopselaphus
nervosus.

Encinetns strigosns. — Elongate oval, rather pointed before and behind,
convex, shining black, very finely and scarcely perceptibly pubescent. Elytra
with well marked distant transverse undulated lines; sutural stria deep, the
others faint, eflfaced towards the base. Beneath finely and densely punctulate
and pubescent, antennae and legs brown. Length 3 mm.; .1-2 inch.

172 J. L. LECONTE, M. D.

Pennsylvania, Bedford Co., July, on oak. Quite different from
Eu. tennintdia and morio by the stronger and more distant transverse
lines of the elytra. The form is also less elongate and the elytra are
not red at the tips.

EucinctiiN pnnctnlatns. — Elongate oval, rather more pointed behind,
convex, dark brown, pubescent. Elytra very densely and finely punctured,
\rithout transverse strite; sutural stria deep behind, obsolete near the base;
other strise wanting. Beneath finely punctulate and pubescent. Length 3
mm.; .12 inch.

One specimen, Detroit, Michigan; Messrs. Hubbard and Schwartz.'
Very distinct by the finely and deusely punctulate elytra, without
dorsal strite.

Dictyoptora rnbripennis. — Black, shining; beak as long as the head,
which is finely channeled, and also transversely impressed. Prothorax as
wide as long, sides and tip separately rounded, so that the front outline is
sinuous each side; disc deeply channeled, uneven each side, with an elevated
oblique ridge running to the side margin near the hind angles, which are acute.
Elytra briglit red, pubescent, rugosely punctured, with the suture, side margin
and four narrow discoidal lines on each, slightly elevated. Antennse com-
pressed serrate, with the second joint short; third a little longer than the
fourth. Length 12.5 mm.; .50 inch.

One 9 specimen, Colorado, Mr. B. H. Smith. The tibiae are flat-
tened, somewhat dilated, and broadly concave. The dorsal channel
of the prothorax extends to the tip, is wider at the middle, so as to be
narrowly rhomboidal in form, and is again dilated at base, which is
nearly straight. The antennjie are half as long as the body, not
strongly serrate. The muzzle or beak is longer and narrower than in
D. per/acetus, though less so than in L^cus, and the elytral sculpture
is somewhat different from both.

Dictyoptcra dimidiata. — Elongate black, very finely pubescent. Head
feebly channeled, short, muzzle broad and rounded. Prothorax bright rufous
trapezoidal, wider than long, channeled, side margins straight thickened, disc
foveate near the front angles, deeply and broadly excavated each side near
the base. Scutellum black. Elytra rufous for nearly half their length, then
bluish-black ; finely rugose, obsoletely striate. Antennse with the second joint
two-thirds as long as the third, which is shorter than the fourth. Length
7.5 mm.; .30 inch.

One 9 specimen, Mariposa, California; Mr. Thevcnet. Similar in
form and sculpture to D. pcr/aceta, and differing chiefly in color.

Dictyoptcra riifu'ollis. — Black, prothorax bright red, elytra blue-
black, finely rugose, substriate. Head concave between the eyes, muzzle
broad and rounded. Prothorax much wider than long, trapezoidal, channeled,
margins thickened, disc deejily foveate near the fr<*nt angles, very much
excavated each side behind, and deeply impressed transversely behind the

AMERICAN COLEOPTERA. 17^

middle; the much thickened side margin is also fovcate about the middle.
Antennae compressed, second joint one-half as long as the third, which ia
scarcely shorter than the fourth. Length 9.5 mm.; ,38 inch.

Colorado and Oregon. Also of the same elytral sculpture and
general form as D. perfaceta^ but with much shorter and more deeply
excavated prothorax.

Pleotomus. — A female of this genus was found by Mr. W. H.
Davis at Cumberland Gap, Kentucky. It differs from two Texas
specimens by the prothorax proportionally longer, and more narrowed
in front. In the absence of a male, I am unwilling to indicate it as a
distinct species.

Elaphidion alienum. — Rather slender, piceous, thinly clothed with

very long (lying hairs. Prothorax nearly as wide as long, coarsely and deeply
punctured, with three narrow smooth spaces; sides broadly rounded. Elytra
deeply and sparsely punctured, punctures becoming obsolete behind the middle,
where only the usual distant piligerous punctures are visible; tip rounded,
sutural spine small but distinct. Antennae nearly as long as the body, slender,
joints three to six with slender spines diminishing in length, and without
sensitive spaces. Length 14.5 mm.; .57 inch.

One specimen, Arizona; Mr. C. V, Riley. A singular and easily
recognized species, bearing a deceptive resemblance to Stenosphcnus,
on account of the sparse punctuation and long flying hairs. The
prosternum is very coarsely punctured, and the mesosternum slightly
convex. The ventral segments are very sparsely finely punctured.
The eyes are as coarsely granulated as in other Elaphidia. It must
be placed near E. irroratum.

Purpuricenus magnifica.s. — Bright orange color, mouth, antennae,

knees, tibiae and tarsi, black ; head, prothorax and abdomen spotted with black.
Elytra black, coarsely and densely punctured, with two broad orange-colored
bands, connected by a "narrow marginal line of the same color. Prothorax
coarsely punctured, without lustre, lateral spine very strong; disc with five
black tubercles, the two front ones being small. Length 38 mm. ; 1.5 inch.

Arizona. I have seen but one 9 of this beautiful addition to our
fauna, which was given me by Mr. A. R. Grote. The antennae are
about three-fourths the length of the body and the outer joints are
more compressed than in P. humeralis. The prosternum is rounded
behind; the mesosternum is protuberant behind, then obliquely decli-
vous. Besides the black spots mentioned in the above diagnosis, the
trochanters and base of the thighs are also black ; the black spots of
the head form a transverse band behind the eyes.

The anterior orange colored band of the elytra is transverse, and
extends along the suture to the orange colored scutellum, and along
the side margin to the base; the posterior band is oblique forwards,

174 J. L. LECONTE, M. D,

commencing about one-fifth fron) the tip, and reaching the side margin
behind the middle; the front outline is angulated near the side;
the tip is obliquely and feebly subsinuate, and the sutural angle is
rounded.

I was inclined to place this species in Oxoplus, but the mandibles
are not emarginate at tip.

I^eptiira aiitliracina.— Elongate, black, finely pubescent. Prothorax
a little longer than wide, gradually narrowed from the base forwards, slightly
rounded on the sides, constricted near the tip; hind angles slightly laminate;
disc convex, finely punctured, dorsal channel faint, posterior impression very
deep, base sinuate margined. Elytra narrowed from the base, obliquely sub-
emarginate inwards at the tip, outer angle of truncature acute, sutural angle
obtuse; surfiice rather finely punctured, jiunctures not much stronger at base.
Length 15—19.5 mm.; .6 — .77 inch.

^. — Fifth ventral segment flattened at tip, with the angles prolonged into
obtuse processes; last dorsal rounded at tip; antennse five-sixths as long as
the body.

9. — Fifth ventral segment slightly flattened at tip, and subtruncate; last
dorsal subemarginate ; antennae two-thirds the length of the body.

One pair, Oregon. x\llied to L. plug if era Lee., (New Spec. 224),
but differs by the prothorax being narrower, less rounded on the sides,
with the hind angles more produced. The terminal processes of the
fifth ventral segment of the % are longer. I have not mentioned the
difference of color as being of specific importance because in this
group of the genus it has but little value. The fourth joint of the
a n ten n PC is nearly as long as the fifth.

S|>alacop!<iis stolata, Newman.

Florida and Ti xas. Well preserved specimens of this species, and
of snffusa have the antennae hispid beneath with long bristles, from
the third to the seventh joint. The first joint of the antennae in all
the specimens before me is nearly as long as the head and prothorax.
This species is hardly difierent from the Cuban Eutlieia \\jiluin, and the
latter genus tor which the'names Euthuorus Duval and Systene Pascoe
have been proposed should be suppressed.

Tanarthrus salicola. — Depressed, ferruginous, opaque, very finely and
densel}' punctulate, finely pubescent. Head large, hind angles rounded, vertex
with a narrow indistinct smooth space, occiput with a very short impressed
line. Prothorax cordate, constricted near the base, dilated in front, where it is
scarcely narrower than its length. Elytra wider than the prothorax, dusky at
base and tip, and with a faint dusky transverse band at the middle. Antennie
with eleventh joint equal to the two preceding united, slightly constrictexl at
the middle. Length 3 mm.; .12 inch.

Great Salt Lake, Utah. I owe two specimens to the kindness of
Mr. Ulke. Similar in form to T. salinus but much smaller and easily
recognized by the head and prothorax as densely punctured as the

AMERICAN COLEOPTERA. 175

elytra, the more cordate prothorax, the dusky elytral bands and finally
by the less elongated terminal portion of the eleventh joint of the
antennae.

Mecynotarsus candidns. — Very pale yellow, clothed with fine cinere-
ous pubescence; disc of prothorax nearly round, not longer than wide, horn
with six rounded teeth each side, and an apical one; bicarinate at the base,
without a short medial carina. Length 2 mm.; .08 inch.

Columbia, S. C. ; Dr. Zimmermann. Less elongate than the Cali-
fbraian M. delicatulm Horn, with the carinse of the horn less distant,
and the space between them not carinate. The elytra are uniform in
color, without a central cloud.

Mecynotarsus elegans. — Brown, densely clothed with depressed silvery
pubescence, horn, disc of prothorax, sutural stripe as far as the middle of the
elytra, transverse band about the middle and oblique band behind the middle
sericeous brown; horn with two approximate carinae extending nearly to the
tip, with three large teeth each side, and a still broader apical tooth. Length
1.7 mm. ; .07 inch.

Capron, Florida; Messrs. Hubbard and Schwartz; abundant on the
seashore. The disc of the prothorax, as in M. Candidas, is nearly
globose, not lon<rer than wide; the horn is a little shorter than the
disc, and the teeth are much larger and stronger than in the other
two species.

Xylophilns impressns. — Brown, pubescent, head dusky. Prothorax
subquadrate, broader than long, broadly rounded at the sides and tip; very
finely punetulate, with a large fovea each side behind the middle. Elytra
nearly one-half wider than the prothorax, elongate oval, transversely impressed
near the base, finely punctured, dusky behind the middle. Antennae with the
outer joints gradually a little wider; eleventh joint ovate, pointed. Length
1.2 mm.; .05 inch.

Texas, two specimens, Belfrage. Related to X. piceus, but smaller,
with the thorax broader, and the impressions deeper and quite sepa-
rate; the elytra more oval, and the antennae more slender, with the
last three joints comparatively wider.

Xylopliillis ater. — Elongate, black, nearly uniformly densely punctured,
clothed witb ratlier long cinereous pubescence. Prothorax as long as wide, sides
rounded in front, tip rounded, disc moderately convex, obsoletely channeled near
the base. Elytra a little wider than the prothorax, oblong elongate, parallel,
rounded behind, scarcely impressed near the base. Antennae rather stout,
hairy, slightly thickened externally, last joint larger, ovate pointed. Length
2 mm. ; .08 inch.

One specimen, Texas, Belfrage.

Xylopliilu.s nebulosns. — Blackish-brown, opaque, finely pubescent.
Head and prothorax very densely punetulate, the latter longer than wide,
gradually slightly narrowed in front, feebly rounded on the sides. Elytra
one-half wider than the prothorax, oblong elongate, sides parallel rounded

176 J. L. LECONTE, M. D.

behind; base reddish-brown; a narrow acutely anejulated transverse band of
sericeous pubescence about the middle, and a similar cloud near the tip; sur-
face coarsely and densely punctured. Antennae rather atout, hairy. Tarsi
yellow. Length 2.5 mm.; .10 inch.

%. — Hind thighs thickened, fringed beneath and broadly toothed; middle
tibi» bent, first joint of midille tarsi fringed; last joint of anteiinre as long as
|he three precedin? unite<l, but not wider; eyes large, front narrow.

9' — Legs simple; antennae gradually but strongly thickened externally,
last joint but little longer than the preceding, pointed at tip; eyes smaller^
front wider.

Pennsylvania; Louisiana. Closely related to X. basalts, but the
prothorax is of a different form ; the basal redness of the elytra is
ill defined, and the angulated sericeous band, of which there is no
trace in X. hasalis is quite distinct. The sexual characters are alike
in the two species.

Xylophilus siibras^ciatas.— Pale testaceous, thinly pubescent; head
and prothorax finely punctured, the former dusky. Prothorax subquadrate,
broader than long, feebly channeled towards the base. Elytra one-half wider
than the prothorax, oblong, less elongate, rounded behind, strongly but not
coarsely punctured ; they are marked with a blackish spot near the suture and
another at the side margin. Antennae stout, joints turbinate, hairy. Length
1.6 mm. ; .07 inch.

%. — Antennae with the eleventh joint as long as the two preceding.

9- — Antennae with the eleventh joint broader, ovate, acuminate.

Middle, Southern and Western States. In one specimen the elytra
are deeply transversely impressed at the middle. The eyes are widely
separated and the front is wide in both sexes.

Xylophilu^ brunnipennis. — Dark-brown clothed with cinereous pu-
bescence. Head and prothorax finely and densely punctulate, the latter wider
than long, sides rounded in front, apex rounded; disc convex, with a transverse
impression near the base. Elytra one-half wider than the elytra, oblong, sides
parallel, rounded behind, testaceous, finely and deeply punctured, obliquely
impressed near the base. Antennae stout, scarcely thicker externally, eleventh
joint ovate, acute at tip. Length 1.8 mm.; .07 inch.

S. Carolina, (Zimmermuun) ; Illinois, (Walsh) ; Texas, (Belfrage).
I observe no sexual differences in the three specimens I have ex-
amined.

Xylopliilns ventricosas. — Smoky brown, densely punctured, varied
with angulated lines and spots of pale yellow. Prothorax nearly twice as wide
as long, sides straight, hind angles obliquely emarginate. Elytra twice as wide
as the prothorax, ventricose. Antennae slender, pale, outer joints a little thicker ;
tibiae and tarsi pale. Length 1.8 mm.; .07 inch.

Southern Suites, two specimens. The pale markings of the head,
prothorax and elytra are (juite complex, and dilhcult to describe, but
the peculiarly large and inflated elytra will enable the species to be
easily recoguized. The eyes are smaller, and the front wider than
usual.

AMERICAN COLEOPlERA. 177

ReTision of the ITnited States species of OCHOD JEUS and
other Genera of Scaraba?i<lje.

BY GEORGE H. HORN, M. D.

OCHOD^US, Lep.
Havino- had occasion of late to examine the Ocliodse,us of our fauna,
I noticed certain characters of very great importance which^appear to
have entirely escaped observation. These have afforded me the means
of presenting an entirely new synoptic table which will render the
recoo-nition of our species much more easy and certain without regard
to sex.

The mentura is described by various authors in a similar manner,
Lacordaire writes : Mentuin subtransverse^ a little narroicer anteriorly,
notched in front, liguJa moderately promineni and entire. I have ex-
amined all our species and one {ferrugineus) foreign, with the follow-
ing result.

0. pectoralis, Lee. — Mentum in the form of a broad wedge with tha
base in front, which is concave longitudinally, the tip being emarginate
and the sides of the base fimbriate with long hairs.

O.ferrugineus, Esch. (Siberia), has a similar mentum, but the base
of the wedge is concave in every direction, while the free lower edge
is more elevated and more arcuate ; it is also emarginate in front and
fimbriate.

0. musculus^ Say. — Mentum as long as wide, narrower in front, tip
broadly emarginate, and with a deep longitudinal impression extending
from base to apex, deeper in front, fimbriate along the sides. A similar
form occurs in simplex and hiarmatus.

0. Vlkei, n. sp.— The form here is an exaggeration of the preced-
ing. The longitudinal impression is very deep, the angles of mentum
elevated (when viewed from beneath) and the tip not perceptibly
emarginate. The impression is here so deep that the mentum appears
very deeply bilobed. The edges are fimbriate.

0. frontalis, Lee, has a mentum as long as wide, feebly emarginate
in front and a feeble longitudinal impression near the front only.

TRANS. AMER. ENT, SOC. V. (23) MARCH, 1876.

178 GEO. n. HORN, M. D.

0. xparsus, Lee. — Mentuiu broader than long, not narrowed in from,
anterior angles rounded, surfiice plane, not impressed, apex arcuate.

0. sfriatus, Lee. — Mentum broader than long, feebly narrowed in
front, tip not eniarginate, a transverse arcuate line of rather long
bristly hairs, causing the mentum at first sight to appear very short,
broadly eniarginate and serrulate in front.

These variations of the form of the mentum have given me the
basis of the synoptic table. Other characters however require special
mention.

In all the species with one exception the prosternum is very short
and truncate or broadly rounded, while in pectoralis the prosternum
is produced into a lobe imitating in a diminished form that of
Ilololepta.

When the head is thoroughly deflexed, the globular eyes are re-
ceived in fossa; at the angles of the thorax beneath. The antennse in
repose pass beneath the eyes, the clubs become approximated and are
received into fossae situated immediately in front of the anterior coxae
on each side of the short prosternum. These fossae are more or less
approximated, in pectoralis separated by a narrow carina, which in the
other species becomes gradually broader as they stand in the table,
(biarniatus should however be next to pectoralis in this respect), until
in sparsus the carina is broad and flat.

The spur of the anterior tibia is moderately long and stout and in
well preserved specimens bears on each side a row of moderately long
^^^^ bristles. The spurs of the middle tibi:« are dissimilar, the
S^^9 outer is slender, the inner broader, slightly curved and pecti-
■nltlH "^'^ along its inner margin. This character, of extremely
l^ji^l rare occurrence in Coleoptera, appears to have been entirely
^^^^ overlooked by those who have described Ochodxus ; it is
very distinctly marked in the Siberian ferrugineus. The posterior
spurs present nothing peculiar, they are slender and long.

The first hind tarsal joint is always long but in pectoralis it is very
long and stout, arcuate, longer than all the other joints toijether and
longer than either spur. This species has the hind tibia? more slender
and longer than usual.

The sutural angle of the elytra is obtuse or rounded, excepting in
pectoralis and biarmatns. In these the tip is sinuate before the suture,
and the angle very distinctly {pectoralis} or obtusely (Jnarmatus)
dentiform.

Certain modifications of the propygidium are worthy of notice.
The posterior margin is always very slightly reflexed especially at its

AMERICAN COLEOPTERA. 179

middle. In this condition it remains in sparsus. The tips of the

elytra pass under this reflexed edge in repose and are thus

^-_-/ ^ locked. In biarmatus and pectoralis the reflexed edge is

ci::^ j simply notched at middle and a small acute tubercle on

each side appears. Through the notch thus formed the

\w/ '^ sutural dentiform process passes and the elytra are in this

\^rp I manner firmly secured in repose. The next modification

results in a groove running the length of the propygidium,

limited on each side by a finely elevated line terminating posteriorly

by joining the reflexed edge which is emarginate between them. These

lines are exactly parallel in simplex, musculus and Vl/iei, divergent in

front m front (I lis and sfriatus.

The pygidium is always short and uncovered in both sexes.

The labrum is very distinctly visible, the anterior angles

HSHj broadly rounded and tip emarginate. In sparsus, how-
1^9 over, the labrum is shorter, much broader, the anterior
angles prominent outwardly but obtuse, the tip is more
deeply emarginate.

Secondarily in importance in the accompanying table come the
sexual characters of the male, and from the tendency of the sexes to
approximate in the fcrm of their hind tibiae, a character is required
which will enable the male to be known even with simple tibiae. The
club of the male antennae is always larger, more convex, and the first
joint more convex on the proximal side, and more decidedly concave
on the distal. The club of the female is of a more decided lamellate
type, narrower and with the joints less enclosing, the first especially
being scarcely at all cupped.

At the apical end of the posterior femora, on the lower face is a

lamella which forms the side of the tibio-femoral

articulation. In many of the species in the male

this plate is developed into an unciform process,

acute at tip. This is entirely wanting in the males

(as I consider them), of pectoralis, simplex, Ulkei,

sjjarsus and striatus, and exists in the others, and

in very well developed males o^ frontalis, a small spiniform tooth occurs

near the middle of both the anterior and posterior femora.

The posterior tibiae % show four types.

First — Tibiae precisely identical (?) in the sexes. I have seen
males only.

Second. — Tibiae broader and more fimbriate S .
Third. — Tibiae obtusely dilated at middle S .

180 GEORGE H. HORT, M. D.

Fourth. — Tibiae toothed at middle % .

The characters of least importance in groupinj^ the species are-
found in the form of the clypeus and the armature of the head.
With one exception (hiarmatus) the upper surface of the head is
simihir in the sexes.

The species may possess stridulating power, the surface of the
propyj^idium is finely alutaceous and with a pearly lustre, and this
is probably the ori];an for the above purpose in conjunction with the
edge of the apical elytral margin.

Tbe elytral stria present a peculiarity worthy of notice. In all the
neighboring genera in our fauna the sutural stria is parallel with the
margin, while the other striaa are slightly oblique; in OchoJpcux,
however, the sutural stria is also oblique and becomes very closely
approximated to the sutural margin at its apical third.

The following table is presented as the result of the grouping of the
characters above-mentioned.

Prosternum lobed in front.

Mentum in the form of a wedge, elevated in front with the basal face
longitudiinally concave. First joint of hind tarsus long, stout anil
arcuate. Clypeus hemihexagonal, anterior edge double, front without

elevations peff oralis.

Prosternum not lobed in front, first joint of hind tarsus long but slender.
Mentum as long or longer than wide, more or less impressed longitudinally.
Mentum longitudinally impressed in its entire length; bead with or
without ridges, but never with an acute median tubercle.
Posterior tibiae of male with an acute tooth at middle.

Posterior femora of male with aa unciform dilatation of the
articular plate.

Clypeus broadly hemihexagonal, witli a crescentic ridge
near the aj)ical margin, front with short transverse

carina luusciilus.

Posterior femora of male without tooth at the tip. Clypeus
broadly hemihexagonal, anterior margin double; head with-
out tubercles or ridges ..siiuple.v.

Posterior tibiae of male slightly dilated at middle.
Posterior femora of male without apical tooth.

Clypeus broadly rounded, anterior margin double; head

without ridges I'lkei..

Posterior tibifB of male not differing from that of female c.xce{)t
being broader and more fimbriate.
Articular plate of hind femora prolonged nearly one-third the
length of the femur, terminating abruptly with an acute angle,
similar in the two sexes.

Clypeus broadly rounded, lateral angles elevated into an
acute tubercle %, or plane 9 biariuatiis.

AMERICAN COLEOPTERA. 181

Mentum very feebly impressed and in front only.
Posterior tibiae as in biarmatus.

Posterior femora male with tooth at tip, and a smaller acute tooth
^ near the apical third which may disappear; anterior femora

usually with an acute tooth at middle.

Clypeus hemihexagonal, anterior margin not double, a small
acute tubercle near the suture; vertex with feeble trans-
verse ridge frontalis.

Mentum shWrt, broader than long, not impressed.

Mentum broader than long, not emarginate in front, with a transverse
arcuate row of bristly hairs, causing the mentum to appear very short,
deeply emarginate and serrulate in front.
Posterior tibiae as in biarmatus.

Posterior femora male toothed at tip.

Clypeus hemihexagonal, margin single; vertex with a short

moderately elevated transverse carina striatns.

Mentum broader than long, not narrowed in front, anterior angles
broadly rounded, surface not impressed, apex arcuate. .
Males unknown.

Clypeus hemihexagonal, margin single; vertex with an acute
moderately elevated tubercle.

Thorax much shorter than any other species, mandi-
bles more prominent, angles of labrum prolonged
laterally sparsus.

Tn the table it will be noticed that certain species are described as
having a double clypeal margin while in others it is single. In the
former case a distinct margin is seen above that to which the labrum
is attached as in Elater. This margin is thickened in tnusculus and
forms the anterior ridge of which mention is made.

Having devoted so much space to the description of the special
characters of the species, and the synoptic table containing nearly
every character of moment, but little now remains except the bibli-
ography and synonymy.

O. pectoralis, Lee, Trans. Am. Ent. Soc, 1868, p. 51. — Color ferruginous
brown. Head roughly sculptured by coarse indistinctly limited punctures.
Thorax with rather sp.irsely placed granules (denser in front), each bearing a
short hair, median line distinet at base only. Elytra rather deeply striate,
striae not closely punctured, intervals slightly convex, irregularly triseriately
punctured, each puncture bearing a short seta. Body beneath sparsely but

clypeus with double margin, the upper forming an arcuate carina, a feeble
transverse carina on the vertex. Thorax sparsely punctured in male, more
densely in the female, median line extremely indistinct even at base. Elytra
striate, strice punctured moderately closely, intervals moderately convex, irregu-

female; sutural angle rectangular. Body beneath sparsely punctured and
hairy. Length .20 — .22 inch; 5 — 5.5 mm.

I have united opacus with muscidus, although they differ somewhat
in the sculpture of the upper surface, for the reason that they both
agree in the sculpture of the head, and all the specimens known of the
former are female and all of the latter male. The sculpture varies in
density in the two males before me.

Westwood describes the clypeus as biangulate, but the figure shows
the ordinary hemihexagonal form of this and several other species.
I think there is no doubt of the synonymy.

Occurs in Michigan, Dakota and Nebraska.

MACRODACTYI.US, Latr.

Several important characters appear to have entirely escaped notice,
and the species although few in number are in a somewhat confused
state.

The antennal club does not diflfer notably in length between the
two sexes.

184 GEO. H. nORN, M. D.

The pygidium is always much longer in the male, the form heing
elongate oval in the one case and broadly triangular in the other.

The anterior and posterior tibia) of the male are without spurs.
There are however, stiff bristles around the end of the hind tibiie
which simulate spurs, but no proper spurs. The middle tibia3 have
two well defined spurs. In the female the tibiae are all normally
provided, that is, the anterior have one and the four posterior two
each.

In the male the post coxal portion of the presternum is elevated in
a long and rather slender process, that of the female is entirely flat
and without elevation. The abdominal segments 2 — 5 of the male
have on each side of the middle an oblique I'ow composed of three or
four coarse punctures, bearing a stiff and nearly erect bristly hair.
The females have a few slender hairs usually arranged without any
marked regularity.

The claws of the male, especially those of the anterior tarsi, are
very much less cleft than those of the female, and are longer and
much less curved.

The discovery of the sexual relations of our species has required a
rearrangement of the synonymy, and the following notes are the result
of their study.

Males. — Anterior and posterior tibiae without spurs, prosternum behind thecoxsB
elevated in a long process, abdomen with stiff hairs arranged in oblique rows
on each side of the middle of segments two to five, pygidium elongate.
Thorax always with recumbent pubescence.

Prosternal process long, slender, as long as the coxae and visible from

the front; abdominal bristles slender SUbsplROSUS.

Prosternal process short, not visible from the front; abdominal bristles

very short aiignsfatus.

Prosternal process long, visible from the froat, tip broader and emar-

ginate; abdominal bristles stout uniformis.

Females. — Anterior and posterior tibiae with spurs, prosternum not elevated
behind the coxae; abdomen with a very few slender hairs, pygidium tri-
angular.

Thorax with recumbent hairs with short vertical setae intermixed, ab-
domen with very few median erect hairs subspinosus.

Thorax with all the hairs of the disc erect, those of the margin recum-
bent, abdomen with many erect hairs along the middle arising from

strong punctures aiigiistatus.

Thorax with the hairs all recumbent as in the male, abdomen with few
erect hairs arising from small punctures unirormis.

^I. MubspinoMii$«, Fab.

Feuiales of this species very rarely occur with the pubescence of
the thorax flat as in the male, they then resemble unij'ormis which

AMERICAN COLEOPTERA. 185

has however, a denser and longer pubescence especially on the elytra.
The prosternal process of the male is as long as the coxa3, arcuate and
compressed. The abdominal setae are rather slender when compared
with those of the two following species. In both sexes the elytral
vestiture is not dense and there are no erect hairs. The male has a
more slender form than the female.

This species occurs especially in the Northern States, northward of
a line from Virginia to Colorado.

M. aiigiif^tatus, Beauv., setulosus, 9 » I^sc.

The male is a larger insect than the preceding. The prosternal
process is short, but little longer than half the coxas. The abdominal
setae are long and stout. The female has the hairs of the disc of the
thorax erect, those of the margin recumbent; the elytra have also
erect hairs near the base. The abdominal segments 1 — 5 have large
punctures, varying in number from 4 to 8 — 10 according to the seg-
ment, which give rise to moderately long hairs, while in suhspiiwaus
these hairs are entirely absent or very inconspicuous.

This species occurs in the Gulf States, but I have seen one female
from Pennsylvania.

.11. iiniroriBiis, n. sp.

Resembles the two preceding in form and differs superficially in the
denser and longer vestiture. Both sexes have the thorax clothed with
recumbent pubescence, and the surface less deeply punctured than in
either of the preceding. The abdominal setas of the male are very
stout and stiff, those of the female few in number and on the first four
segments only. The prosternal process of the male is long, wider at
tip and moderately deeply emarginate. Length .40 inch; 10 mm.

Occurs in Arizona.

The sexes may be readily distinguished by the structure of the
antennae, the club of the male being nearly as long as the funicle and

ill the female much shorter. The abdomen viewed in profile from
the side is convex along the median line in the female and concave in
the male.

The spurs present no special diflference in the majority of the species.
In three however, {valida^ alhlcollis, mlcafa'), the outer spur of the
male hind tibias is broader than the other and truncate at tip, (beini;
less evident in the first than in the other two), while the females of
these and both sexes of all the others the spurs are slender, acute
and similar.

The frontal suture is normally deeply impressed, but in five tlu-
suture although traceable is not impressed.

The thorax bears a median, moderately deep impression in sduic
species, but is even in the greater number. Behind the apical margin
and parallel with it, is a moderately deeply impressed submarginal line
which is almost entirely obliterated in two species.

In those species with the sulcate thorax, the posterior tarsal claws
are either absolutely or very nearly simple, while in all the others the
tip is decidedly bifid. The clypeus is usually rounded in front, the
margin more or less widely reflexed, two species (truncata, pusi7/a).
have the clypeus truncate in front, the sides not arcuate and the
angles very distinct.

Based on the above characters, the following table of the species
will greatly assist in the identification of our species.

Thorax without median fi;roove.
Clypeus not prolonged.

Frontal suture very indistinct or entirely ohliterated.
Sub-apical and basal marginal grooves distinct.

Clypeal margin narrowly reflexed. Anterior tibioe tridentate.

Head, thorax and legs rufous, the latter very rarely piceous;
elytra with broad pale margin.

Elytra piceous with feneous tinge riiscula.

Elytra brilliant metallic green flilgida.

Clypeus truncate, angles rectangular triincata.

Clypeus prolonged in advance of the labrum clypeata.

Thorax with a rather broad and deeply impressed median groove.
Disc of the thorax on each side of median line punctured.
Punctures of disc arranged in an even space.

Outer spur of hind tibiaj %, very much broader than the inner and

distinctly contorted altoicollis.

Outer spur of hind tibite % , somewhat broader, not contorted.. valitla.

Punctures of disc arranged in a broad fovea on each side sulcata.

Disc of thorax very smooth.

Clypeus. subtruncate .anteriorly, sides not rounded. Hind tibial spurs
slender, similar and equal in the sexes pusilla.

D. rotundata^ Lee, is omitted from the above table, as it appears to
constitute a distinct genus.

D. clongata. Fab. — Body beneath, head and thorax piceous. Elytra vari-
able, testaceous or pieeo-testaceous with an asneous surface lustre of variable
intensity but evenly disposed. Head and thorax densely punctured, the former
sparsely pubescent, the latter sparsely pubescent % , or densely pubescent J.
Clypeal margin moderately reflexed, frontal suture very indistinct, not im-
pressed. Scutellum with moderately dense, yellowish white, recumbent pubes-
cence. Elytra rather coarsely punctured, sparsely pubescent. Body beneath
sparsely punctured, rather densely clothed with long scale-like hairs. Anterior
and middle legs and hind femora yellowish testaceous, hind tibiae (except at
base) and tarsi jjiceous.

The sub-apical and basal marginal lines are deeply impressed. The
hind tibial spurs are both slender and acute in the two sexes. The
pubescence of the thorax is always denser and more persistent in the
female, and gives it the appearance of a distinct species, especially as
the hind angles of the thorax are less prominent. By an examina-
tion of those species in which the hind angles of the thorax are well
marked, it will be at once noticed that wliile the males have the thorax
sinuate posteriorly and the angles acute, the females have the sides
posteriorly obli(|ue, and the angles obtuse or even indistinct. From
this it is evident that too great stress must not be laid on the form of
the thorax in the attempt to separate species.

This species occurs rather abundantly from Canada to the Middle
States.

I>. Slibvlttata, Lee. — Color testaceous, elytra with distinct asneous tinge,
frequently with a darker vitta extending from the humeral to the apical
unibone with the color always more densely aeneous at these points. Head
rugoscly punctured, sparsely pubescent, frontal suture nearly obliterated.

188 GEO. 11. HORN, M. B.

clypeal margin narrowly reflexed. Thorax rather coarsely but not densely
punctured, median line very feebly impressed, surface sparsely pubescent and
similar in the sexes, sub-apical and basal marginal lines deeply impressed.
Elytra rather coar.sely punctured and wrinkled, very sparsely pubescent. Body
beneath sparsely punctured and pubescent. Legs testaceous.

This species differs from the preceeiiug in having the tliorax less
densely and more coarsely punctured, and similarly pubescent in the
two sexes, the hind tibiae entirely testaceous, and finally by the tri-
fling character of the darker spots at the humeral and apical uujbones.
It is also somewhat larger.

Occurs in Canada.

I>. caimdoiiNis, n. sp. — Piceo-testaceous, elytra greenish bronze with
margin paler. Head densely and rather coarsely punctured, sparsely pubes-
cent, frontal suture nearly invisible, very strongly arcuate at middle, clypeus
with rounded angles, margin deeply reflexed. Thorax sparsely punctured, a
slight impression near the middle of the side, sub-apical and basal marginal
lines distinct. Elytra coarsely punctured, picco-testaceous, surface uniformly
and rather brightly seneous. Legs entirely testaceous. Anterior tibiie with
the upper tooth obsolete. Body beneath sparsely punctured, and sparsely and
finely pubescent. Length ..36 inch; 9 mm.

This Species resembles elongata, but the clypeus has a much more
broadly reflexed margin, the thorax less punctured, the hind tibiic
entirely testaceous, and the anterior tibia) bidentate only.

Occurs in Canada.

I>. testacoa, Kby. — Pale testaceous, elytra with very faint tinge of reneous.
Head coarsely and densely punctured, with very few hairs. Clypeus with
rounded angles, margin rather broadly reflexed, frontal suture distinct but
not impressed. Thorax sparsely punctured, sparsely pubescent, bind angles
distinct but not prominent, anterior sub-apical and basal marginal lines feeble.
Elytra coarsely punctured, sparsely pubescent. Body beneath sparsely punc-
tured and pubescent. Legs testaceous.

This species might be mistaken for a pale eloiigata, but the thorax
is much less densely punctured, and the hind angles of the % thorax
less prominent. The punctures of the thorax are finer than in i^iih-
vitlata, and there is no trace of the median Hue as in the latter species.
The clypeus is rather more widely reflexed than in cither of the two
mentioned, though less so than in canadensis, from which it also difl'ers
in the tridentate anterior tibiae.

Occurs in Canada and Vermont.

D. palleiiM, Lee. — Pale testaceous above and beneath, elytra with very
faint tinge of aeneous. Head very densely and coarsely punctured, very
si)ar3ely pubescent, frontal suture obsolete. Clypeus with rounded angles,
margin very feebly reflexed. Tliorax rather coarsely punctured, punctures at
the sides denser and sub-confluent, sides behind the middle obli<iue, angles
obtuse, surface sparsely pubescent. Elytra coarsely but sparsely punctured,

finely rugulose. Body beneath sparsely punctured and finely pubescent. Legs
testaceous.

This species, of which I have seen but one female, resembles the
preceding, but is shorter and more robust, and with the margin of the
clypeus very narrowly reflexed. The basal and sub-apical lines are
still more obliterated.

One specimen, California, (Leconte).

D. Crotchii, n. sp.— Form slender as in subvittata, color rufo-piceous, elytra
bright metallic green with very narrow pale border, legs testaceous or rufo-
testaceous. Head piceous, clypeal margin paler, surface moderately densely
punctured, sparsely pubescent, frontal suture impressed, clypeal margin moder-
ately reflexed. Thorax piceous, form of subvittata, moderately densely punc-
tured, sparsely pubescent, sub-apical line feebly impressed, basal marginal line
nearly obsolete. Elytra rather finely punctured, punctures nearly obliterated
by the fine transverse wrinkles, surface finely pubescent. Body beneath pice-
ous, sparsely pubescent. Legs testaceous or piceo-rufous. Legs and form of
subvittata.

This species begins a small series, the members of which are ex-
tremely difficult to separate in description. The present species is
more especially distinguished from those which follow, by the elytral
sculpture and the feeble marginal thoracic lines. At first sight the
elytra will be seen to present a much less shining surface.

Several specimens were collected by myself in the high Sierras
of California, and others subsequently by my lamented friend G. R.
Crotch, in whose memory it is named.

». Baokii. Kby.— Head, thorax, body beneath and legs nearly black,
elytra bright green or bronze, with at most a very narrow paler margin.
Head black, moderately densely and coarsely punctured, frontal suture im-
pressed, clypeal margin narrowly reflexed. Thorax moderately densely punc-
tured, espe'cially at the sides. Elytra coarsely but not closely punctured. Body
beneath sparsely pubescent and punctured.

Specimens of this species rarely occur with the elytra more or less
testaceous, these must be considered partially immature, the thorax is
however always black, and the clypeal margin never pale.
Occurs in Canada and northward, also in Utah and Oregon.

I>. fnscula, Lee— Rufo-testaceous, elytra piceo-seneous with moderately
broad pale margin. Head moderately densely and coarsely punctured, sparsely
pubescent, frontal suture impressed, clypeal margin moderately reflexed.
Thorax sparsely but moderately deeply punctured, intervals shining, sparsely
pubescent. Elytra piceo-£eneous with moderately broad pale limb, surface very
coarsely punctured, sparsely pubescent. Body beneath sparsely punctured
and pubescent.

Specimens often occur with the body beneath, head and thorax
piceous, legs rufo-piceous. The especial characteristics of this species

190 GEO. n. HORN, M. D,

are the sparsely punctured thorax, coarsely punctured elytra and the
deep bronze tinge of the surface.

Occurs in the southern Atlantic States from Maryland to Georgia,
also in Ohio.

D. iul^uln, Lee. — Rufo-testaceous, elytra brilliant green shining with
narrow pale limb. Head very coarsely and densely jmnctured. sparsely pubes-
cent, frontal suture impressed, clypeal margin narrowly reflcxod. Thorax
rather sparsely but coarsely punctured, sparsely pubescent. Elytra brilliant
metallic green, coarsely and deeply punctured, smoother at basal third, surface
sparsely pubescent. Body beneath rufo-testaceous, sparsely punctured and
pubescent. Legs paler.

I have seen only females of this species. It can only be confounded
in description with ftmadn from which it differs by its larger size,
more coarsely punctured thorax and the color of the elytra. Varieties
rarely occur with the elytra testaceous.

Occurs in Oregon and Vancouver.

D. truncata, Lee. — Rufo-piceous. Head coarsely punctured, sparsely
pubescent, frontal suture deeply impressed. Clypeus truncate in front, sides
slightly convergent, angles acute, margin rather broadly reflexed and testa-
ceous. Thorax finely rugulose, sparsely pubescent. Elytra with paler limb,
surface bronzed, punctured and coarsely wrinkled. Body beneath sparsely
punctured and pubescent. Legs testaceous or piceo-testaceous.

This species which is about the smallest, is easily known by the
truncate clypeus and the thoracic sculpture.
Occurs in Colorado, Oregon and California.

I>. elypoata, n. sp. — Form robust, color piceous, elytra luteous without
metallic lustre. Head coarsely and densely punctured, frontal suture not im-
pressed. Clypeus prolonged over the labrum, rounded in front, slightly dilated
at the sides, margin moderately reflexed. Thorax coarsely and densely punc-
tured especially toward the sides, sub-apical line obliterated at middle, basal
marginal line feeble, disc moderately convex, sides very obtusely sub-angulate,
posteriorly oblique, hind angles obtuse, margin in front crennlate. Elytra
luteous without surface lustre, obsoletely tricostate, surface coarsely punctured.
Body beneath sparsely punctured, abdomen and sternal side pieces finely
alutaceous, surface sparsely pubescent. Legs piceo-testaceous. Length .42
inch; 10.5 mm.

This .species has somewhat the aspect of the succeeding group, but
has no median thoracic line. The prolonged clypeus will serve to dis-
tinguish it at once from all others in our fauna.

I>. albieollis, Burm. — Testaceous or piceo-testaceous, elytra with moder-
ate aeneous tinge. Head coarsely and densely punctured, moderately pubes-

D. valida, Lee. — Resembles the preceding in form and sculpture and
differs as follows: — Head, thorax, body beneath and legs % piceous, 9 rufous.
Elytra brilliant metallic green with very narrow pale margin. Hind tibiae 'J,
with the outer spur very little stouter than the inner, not twisted but obtuse
at tip.

Occurs in California and Oregon.

D. sulcata, Lee. — Piceous, elytra deeply bronzed. Head coarsely and
densely punctured, frontal suture impressed, occiput with vague chevron-like
impression, clypeal margin feebly reflexed. Thorax very sparsely punctured,
the punctur3s being more densely crowded in the median impression, and a
vague fovea on each side, surface sparsely pubescent. Elytra coarsely punc-
tured, surface deeply bronzed, sparsely pubescent. Body beneath sparsely
pubescent and hairy. Legs testaceous, hind tibiae and tarsi darker.

In the male of this species, the hind tibial spurs are slender
and equal.

Occurs in New Mexico.

D. pnsilla, Lee. — Piceo-testaceous. Head rugulose, frontal suture very
vague, clypeus subtruncate, sides slightly convergent, margin moderately re-
flexed. Thorax with fine, very sparsely placed punctures, median groove
moderately impressed, surface rather shining, sparsely pubescent. Elytra
punctured, sparsely pubescent, surface with very faint bronze tinge. Body
beneath sparsely punctured and pubescent. Legs piceo-testaceous, hind tibise

This genus agrees with Dichelonj/cha in all respects, e.xcept in tlie
following characters.

Head moderately deeply inserted, e3'es partially concealed by the
anterior angles of the thorax. Thorax without trace of sub-apical,
impressed line. First abdominal segment in great part concealed by
the coxae, abdomen apparently with five segments only.

In Dichelonycha the head is prominent, the eyes distant from the
thoracic angles, the first abdominal segment at least half visible at the
sides, and distinctly visible at middle. The antennae of Diclubni/chi
are nine-jointed.

Three species are referred to this genus, difiering especially as
follows :

C rotundata, Lee, (Dicheloni/cha), Jonm. Acad., 1856, p. 281.— Form ob-
lonc, color brownish testaceous without metallic lustre. Head coarsely and
moderately deeply punctured, frontal suture distinct, feebly impressed. Clypeus
truncate in front, margin feebly, angles more broadly reflexed and slightly
prominent. Thora.x rather more than twice as broad as long, sides gradually
divergent posteriorly, hind angles very broadly rounded, disc shining, coarsely
but sparsely punctured, margin with rather long fimbrise. Elytra oblong,
slightly broader behind, coarsely punctured, slightly rugulose at middle, and
with very sparse and inconspicuous pubescence. Body beneath very sparsely
punctured and pubescent. Length .32 — .40 inch; 8 — 10 mm.

This species may be known by its ten-jointed antenna). Its form
and general appearance cause it to resemble some of the members of
the group Rhizofrogi.

Occurs from Oregon to Fort Yuma, Cal., but rare.

C. socialis, n. sp. — Form oblong oval, narrower in front, color brownish
testaceous, sides of elytra somewhat paler. Clypeus hemihexagonal, margins
reflexed, more broadly in front, anterior edge emarginate, angles moderately
prominent, surface roughened by the confluence of large but superficial punc-

tiires. Head densely and coarsely punctured in front, gradually more sparsely
posteriorly. Thorax twice as broad as long, anterior angles prominent and
partially concealing the eyes, sides slightly sinuate in front, rather broadly
arcuate at middle, hind angles broadly rounded, surface sparsely punctured
and with a few short recumbent hairs; margins fimbriate. Elytra oval, broad-
est behind the middle, humeri feebly prominent, apex subtruncate, surface
very finely alutaceous and sub-opaque, sparsely and finely punctured, each
puncture with a very short hair. Body beneath paler than above, sparsely
punctured and sparsely hairy. Legs pale testaceous. Length .40— .50 inch ■
10-12.5 mm. '

The sexes are distinguished by a slightly longer club of the male
antennae. This species agrees with rotundata in the form of the
clypeus, its form is however more robust, the humeri much less dis-
tinct, and the sides of the elytra less parallel. It differs from both
•species by the number of the joints of the antennse.

Several specimens were collected by Dr. Edward Palmer, on the
island of Guadalupe, on the coast of Lower California.

€. ovipeiinis, n. sp.— Form elongate oval, color testaceous. Head coarsely
but very Fparsely punctured, frontal suture distinct, feebly impressed. Clypeus
rounded in front, margin moderately reflexed. Thorax twice as broad as'long,
sides gradually divergent posteriorly, hind angles broadly rounded, surface
smooth, sparsely and not coarsely punctured, margins with long fimbrise.
Elytra oval, slightly broader behind the middle, humeri obtusely roundedj-.
surface very sparsely punctate and with inconspicuous pubescence. Body be-
neath very sparsely punctured and sparsely hairy. Length .30 inch ; 7.5 mm.

The apterous body and eight-jointed antennae serve to distinguish
this species. The clypeus also differs considerably in form from
rotundata.

The third and fourth joints of the antennae are moderately lono-
and appear to be connate, each one having the appearance of beino-
formed by the fusion of two joints. This will account for the antenn^
being eight-jointed in this, and ten-jointed in the preceding species.

I have but one specimen $ , from Nevada.

The three species present an extremely interesting series, their
salient characters being as follows :
C. rotundiiia, Lee.

Clypeus emarginate and angulatc on each side. Antennce ten-
jointed. Elytra oblong, humeri distinct, wings well developed and
flexed, adapted for flight.

C. socialis, Horn.

Clypeus as in rotundata. Antennae nine-jointed. Elytra oval,
humeri obtuse, wings rudimentary not flexed, and not adapted for
flight.

194 GEO. H. HORN, M. D.

C OTiponnis, ITorn.

Clypeus broadly rounded. Antenna) eight-jointed. Elytra oval,
humeri obliterated, wings entirely wanting.

TRICHIUS, Fab.

The sexual characters of the species require primary attention.
The pygidium of the male is always more convex than that of the
female, and the tip somewhat inflexed. This affords the means of
distinguishing the sexes at all times.

In delta the males have the anterior tibiiv; bidontatc, in the female
tridentate, the anterior tibial spur is less developed in the male, and
the hind tibiEC of the same sex have a small obtuse tooth at the middle
of the inner side. The middle of the posterior margin of the fourth
ventral segment is elevated in the male and flat in the other sex.
This species has been separated by Burmeister, and with its congeners
named Triijonopeltastcs. The tibial differences in the sexes form the
characters of the genus which may for convenience be continued.

The other species of Trichius have the tibiae similar in their denta-
tion in the sexes. T.pi<jer and texanus have no anterior tibial spur in
the jnale, while it is always present iu the males of the other species,
although much feebler in the males than in the females.

In bibens and viridulus the females have the pygidium sinuate ou
each side near the tip, the tip being truncate. This sinuation is
hardly observable in the males.

These characters reduced to the tabular form give the following
result :

Anterior tibise similarly dentate in the sexes. (Triciiiu.s.)
Anterior tibiae % without spur.

Body beneath and pygidium rufous; anterior tibite % moderately stout.

or rufo-pioeous, third and fifth intervals more convex, subcostiform, second and
fourth intervals moderately densely punctate, moderately hairy; two white
fascife one slightly in front of, the other slightly posterior to the middle, ex-
tending obliquely forward from the margin, attaining the fifth, rarely the third
interval ; a space of velvety aspect, exterior to the fifth interval and posterior
to the forward band and divided by the posterior. Body beneath and femora
piceous with tseneous tinge, clothed with long white silken hairs. Abdomen,
pygidium, tibise and tarsi, rufous. Pygidium with alutaceous surface clothed
with short hairs at middle, at sides frequently a white scaly space with longer
hairs.

The male has no anterior tibial spur, and the tibia at tip is very obliquely
truncate, the inner face being moderately broad.

This species occurs more especially iu the Northern States as far
west as Missouri.

T. texanus, n. sp. (Candeze mss.)- — Body above and beneath black, shi-
ning. Head densely punctulate. Thorax moderately densely punctured, and
with the head, clothed with short erect pubescence. Elytra with intervals three
and five more elevated and smoother, two and four flat, moderately densely
punctured and pubescent; two oblique white bands and lateral velvety spot as
in piger, frequently also a subscutellar short white line, and another on the
second interval. Pygidium alutaceous pubescent, a white space on each side.
Body beneath and legs black, moderately hairy. Similar in size to piger.

The male has the anterior tibise very stout, the inner face broad and without
terminal spur. The thorax equally punctured and with whitish hairs. The
pygidium is much less conspicuously pubescent than in the female.

The female has the thorax more coarsely punctured and a smoother space
within each hind angle. The angles have a narrow white space on each, and
the hairs are longer than in the male and yellowish. The pygidium is also
more densely hairy, the hairs yellow and longer than in the male.

In both sexes the thorax is less densely punctured than in piger.
Occurs in Texas and Florida.

T. aflinis. Gory. — Body above and beneath and legs black, with slight
tinge of bronze, disc of elytra usually paler. Head moderately densely, thorax
sparsely punctured, sparsely pubescent. Elytra with intervals three and five
slightly more convex, two and four very sparsely punctured; two white bands,
subsutural white line and velvety space as in te.ranus. Pygidium with lateral
white space moderately densely alutaceous and pubescent. Usually smaller
than piger.

Resembles piger ^ but with a smaller and less punctured thorax, and
differs especially in the sexual characters and the very sparse punc-
tures of the second and fourth elytral intervals.

In the female the pygidium is slightly flattened near the tip.

Occurs from Canada and New Hampshire to Georgia.

T. bibens. Fab. — Body above, beneath, and legs bright metallic green,
elytra rufo- testaceous with slight aeneous lustre. Head densely punctured.
Thorax more coarsely but less densely punctured, clothed with short erect hair.

196 GEO. II. nORN, M. D.

Elytra with intervals very nearly equal, the second and fourth more densely
punctured and hairy. Body beneath moderately hairy. Pygidium punctured
and alutaceous, moderately hairy, with narrow lateral white space.

The male has a slender, straight anterior tibial spur. The pygidium of the
female is distinctly sinuate on each side near the tip, and the tip truncate.
There are no oblique transverse bands on the elytra and no trace of them, and
no lateral velvety space.

This species is especially abundant in Virginia, rarely occurring north
of there, although extending its habitat toward the Gulf States.

T. viridiiliis, Fab. — Entire surface brilliant metallic green. Head sparsely
and finely, thorax more coarsely punctured, sparsely clothed with short erect'
hair. Elytra with intervals equal and nearly equally punctate. Pygidium
coarsely alutaceous. Body beneath sparsely pilose.

This species more nearly resembles affinis in form. The elytra with,
at most, mere traces of the transverse bands but no lateral velvety
