.4 iiioiiograpli of the species of CRYPTOHYPNUS of
Boreal America.
BY GEORGE H. HORN, M. D.
In the printed and other comments which were made on Dr.
Hamilton’s paper on the distribution of many species in common
in the Arctic regions of both continents, my attention happened to
be drawn especially to this genus from the fact that several forms
had just appeared which seemed to be identical with those of Europe,
and which had not, as yet, appeared in our lists. These were made
the subject of a short note, in “ Entomological News,” which closer
study has shown me to be inaccurate in many of its statements, due
in part to the lack of types, and as much to important omissions of
details in the best European descriptions. The subsequent pages
will show that several of our forms are parallel with those of Europe,
in fact deceptively resembling them, but are readily separated by
excellent structural characters hitherto unobserved.
The number of species of Cryptohypnus known being less than
one hundred, has not made it unwieldy or difficult to handle, conse-
quently but little attempt has been made to subdivide it. C. G.
Thomson, in his Skand. Col. vi, restricts the name Cryptohypnus to
those species which have the prosternal sutures straight and Negas-
trius to those with the sutures arcuate, although he seems to place

greater reliance on other cliaracters which have far less value in a
larger number of species. He again subdivides Negastrius, sepa-
rating those s})ecies as Zorochrus which have the prosternal sutures
double and excavate. If any division of Cryptohypnus be thought
necessary, that based on the form of the prosternal sutures appears
to be the only one desirable, from the fact that, between the two
forms, the sharpest line of demarcation is observed.
The existence of the double grooved sutures in a group of small
species was first observed by Thomson, but cannot be used for generic
separation as it would remove certain species from that close approxi-
mation in which they should be placed. It has also been observed
in our species of that series that the groove is far more distinctly
defined in the female than in the male. It is in this group that very
notable sexual peculiarities exist in the form of tubercles on the first
or first two ventral segments in the males of Melsheimeri and caurimis
respectively, or in a small ])ubescent spot at the middle of the second
ventral in the female of c/radarms. In quadriguttatm (tetragraphii^)
and dermestoides of Europe, the anterior tibiae are much broader in
the male than in the female. These, too, have an elevation or tu-
bercle on the first ventral segment of the male which seems to have
escaped the notice of European students.
Another sexual character has been observed in the two species
with non-striate elytra. In the centre of the prosternum of the male
is a small, densely punctured spot, bearing, in well-preserved speci-
mens, a short brush of hair.
One species, Httoralis, is notable in having much shorter legs than
normal, the tibice beset with short, stiff, bristle-like hairs, after the
manner of many arenicolous species. The tibial spurs are also better
developed. In the species with the curved prosternal sutures the
spurs are far less distinct than in those with straight sutures.
It will be observed also that the terminal joint of the maxillary
palpus varies in form, but without that degree of difference enabling
the character to be used for systematic purposes. Illustrations will
be found on the plate, to which the reader is referred.
The species known to me seem to divide very naturally into groups,
and it is proposed so to treat them to avoid the use of a long analytical
table.
They are, therefore, divided as follows ;
Prosternal sutures straight, parallel, or very little convergent posteriorly 2.
Prosternal sutures arcuate and very evidently convergent posteriorly 3.

2. — Tibife stouter than usual, the outer side beset with short spinules, the spurs
very distinct Group LITTORALIS.
Tibiffi slender, not spinulose externally, the spurs usually very small and
indistinct.
Depressed opaque species, thorax coarsely and closely punctate.
Group SQUALIDUS.
More or less convex and shining, thorax variably punctate, but never
opaque, the median line more or less impressed.
Hind angles of thorax slender and divergent, the basal incisure well
marked; surface not distinctly pubescent.. -Group HYPERBOREUS.
Hind angles of thorax stouter, scarcely at all divergent, basal incisures
feeble; surface pubescent Group ABBREVIATUS.
3. — Elytra with the striae entirely, or in great part obliterated ; in the latter
case, those near the suture alone evident Group PECTORALIS.
Elytra with all the striae entire 4.
4. — Depressed species, dorsum quite flat, surface opaque, densely punctulate
and pubescent; hind angles of thorax with short carina.
Group STRIATULUS.
Convex species.
Thorax coarsely granulate, usually with a smooth elevated median line.
/ Group CHORIS.
Thorax unequally sculptured, either subasperate or more densely, coarsely
punctate near apex, posteriorly smoother, median line usually smooth
Group MELSHEIMERI.
Thorax equally punctate, either sparsely or moderately closely ; elytra
ornate Group PERPLEXUS.
The groups which follow are arranged in a manner to show what
seems to be a natural sequence based on facies.
In conclusion, I wish to acknowledge my indebtedness to Dr.
Hamilton and Mr. Ulke for the loan and gift of specimens, and to
Mr. Blanchard for first having called my attention to the pubescent
spot in the abdomen of gradarms, thereby suggesting a new line of
investigation which has resulted profitably.
Group LITTORALIS.
Prosternal sutures straight, very nearly parallel. Maxillary palpi
moderate in length, the last joint elongate oval, obliquely truncate
at apex. Tibiae shorter than usual, the outer edge beset with short
spinules, the terminal spurs well marked. Form robust, body ap-
terous.
This group contains but one species so unlike those which follow,
as to lead to the supposition that it should be more completely sepa-
rated. There are, however, no differences of sufficient importance
to warrant generic separation.

GEO. H. HORN, M. D.
littorali!4 Escb. — Form robust, convex, brownish piceous or darker fer-
ruginous, scarcely sbining. sides of tborax (more broadly beneath) and elytra,
antenme and legs yellowish testaceous; antennae rather stout, joints 6-10 as
broad as long, eleventh oval ; bead sparsely, rather coarsely punctate ; thorax
broader at middle than long, sides arcuate, sinuate in front of the hind angles,
which are acute and feebly divergent, the carina short, hut well marked ; disc
sparsely punctate, basal margin without trace of incisure: elytra oval, humeri
obliquely rounded, disc rather deeply striate, strise, not punctate, intervals con-
vex, sparsely punctate near the base, gradually becoming granulate toward the
apex ; body beneath piceous, except the flanks of the prothorax, these finely
punctate externally, more coarsely near the inargin ; under surface punctate,
hut not closely, except on the last ventral segment, which is quite rugose.
Length 8 — 11.5 mm. ; .32 — .46 ineh.
In well preserved specimens the surface above and beneath is
sparsely fulvo-pubescent. A variety entirely yellowish is mentioned
by Mannerheim and Candeze, not the result of immaturity, as might
be suspected, but truly varietal, as has been observed in many species
living along the sea-coast.
Seems to be abundant on the Alaskan sea-coast.
Group HYPERBOREUS.
Prosternal sutures straight, very slightly convergent posteriorly.
Legs slender, tibial spurs small. Maxillary palpi not prominent,
the last joint triangular, as in the squalidus group. Thorax smooth,
sparsely punctate, median line more or less impressed, the basal in-
cisures distinct, hind angles long, slender and divergent. Surface
nearly, or quite glabrous, body winged.
This group contains but three species, as far as known to me, espe-
cially notable by their oblong, feebly convex form, nearly glabrous
surface, subsulcate thorax with slender hind angles.
The species are separated as follows :
AntenuiB entirely ferruginous.
Anteimse rather slender, the joints longer than wide g;raii(licollis.
Antenna stouter, joints triangular, as wide as long liyperboretis.
Antenna piceous, except at base, the joints longer than wide.
Elytral intervals fiat Saiiboriii.
Elytral intervals convex barbatiis.
These inhabit the more northern or elevated regions of our country,
one of them {hyperhorens) having a circum-polar distribution in both
hemispheres.
C’. graiKlicollis Lee. — Oblong, moderately convex, piceous shining, with
faint metallic lustre, elytra paler than the thorax; surface scarcely pul)escent ;
antcTina ferruginous, joints all longer than wide; front fiat, coarsely not closely

punctate ; thorax distinctly longer than wide, sides scarcely arcuate, hind angles
very slightly divergent, distinctly carinate, carina short, disc moderately convex,
median line vaguely impressed posteriorly; surface sparsely punctate, a little
more closely in front and near the front angles; elytra a little wider than the
prothorax at their middle, humeri obtusely rounded ; disc moderately convex,
rather deeply striate, strim punctate, intervals slightly convex, sparsely punc-
tate ; prosternum moderately coarsely, but sparsely punctate, the lobe moderately
prominent, arcuate in front, limited behind by a feeble transverse line, propleura;
moderately closely coarsely punctate, with finer punctures between, not opaque;
metasternum moderately closely punctate, punctuation coarse and fine inter-
mixed ; abdomen similarly punctate, the last segment more coarsely; legs rufo-
testaceous ; entire body beneath paler than above. Length 9 mm. ; .36 inch.
A much more robust species than any of this group and with the
thorax of larger area relative to the elytra.
A specimen in the LeConte cabinet, which I have no doubt is the
male, has a rather more slender form, the sides of thorax sinuate in
front of the hind angles, which are consequently more slender and
divergent. Its color is slightly darker. These differences, in view
of the opposite sex of the specimens, seem purely sexual and not
specific.
Occurs in Canada and Oregon, S .
C. hyperboreus Gyll. — Moderately elongate, depressed, piceous brown,
moderately shining, antennsE and legs ferruginous; surface very sparsely pubes-
cent ; antennse short, joints 4-10 as wide as long ; head slightly convex at middle,
sparsely punctate; thorax as broad as long 9 > or a little longer % ; scarcely
narrowed in front, sides regularly arcuate in front of the hind angles which are
slender, divergent, and with a short carina; surface shining, sparsely punctate,
median line vaguely impressed ; elytra wider than the thorax, oblong oval,
widest at middle, humeri rounded, disc rather depressed, finely striate, strife
indistinctly punctate at middle, intervals flat, sparsely punctate; prosternum
sparsely punctate at middle, densely and finely at the sides, the lobe moderately
prominent, arcuate in front, limited behind by a transverse impression, propleurse
densely finely punctate, with coarser punctures intermixed, rather opaque, dis-
tinctly pubescent; metasteruum sparsely punctate; abdomen closely punctate
with coarse and fine punctures intermixed, and with fine brownish pubescence.
Length 6.5 — 8 mm. ; .26 — .32 inch.
This species is very nearly as depressed as those of the squalidus
group. It is paler in color than Sanborni, and without the faint
metallic lustre of that species and differing also in the color of the
antennae.
This species is known from Lapland, Siberia, Kamtschatka, and
on our own continent in Alaska.
C’. $$anborui Horn. — Oblong, moderately convex, piceous black, moder-
ately shining, sometimes with a faint bronze surface lustre, very slightly pubes-
cent; autennfe slender, feebly serrate, joints all longer than wide, iiasal joints

GEO. H. HORN, M. D.
nifo-testaceons, the outer joints piceous ; head si>arsely punctate; thorax longer
than wide, not narrowed in front, widest at middle, sides feebly arcuate, sinuate
in front of the hind angles, which are slender, acute, distinctly divergent and
carinate above, di,sc moderately curved, the median line vaguely impressed from
base to apex, basal incisures distinct; surface sparsely finely punctate: elytra
oblong oval, widest behind the middle, humeri oblique, disc striate, strise dis-
tinctly punctured, intervals flat, sparsely punctate, but more coarsely than the
thorax ; jn-osternal lobe moderately prominent, the border distinctly beaded, a
transverse impression posteriorly, coarsely punctate in front, more finely and
sparsely toward apex, punctuation at sides denser and intermixed, propleurte
rather densely punctate and more opaque, with coarser and fine punctures inter-
mixed ; epipleurre jiale; metasternum and abdomen rather densely punctulate
with coarser punctures intermixed ; legs rufo-testaceous, tarsi darker. Length
5,5 — 7 mm.; .22 — .28 inch.
The hind angles of the thorax at tip, the epipleurae of the elytra
and a narrow border of the under side of thorax are usually rufes-
cent. The median line of the thorax, although feeble, is distinctly
impressed from base to apex ; all the strite of the elytra are punctate.
Occurs in the White Mountain region of New Hampshire, where
it was first collected by Mr. F. G. Sanborn, and since by Blanchard,
Henshaw and others.
barbatiis Sahib. — Oblong, moderately convex, piceous black, moderately
shining, sparsely clothed with short, inconspicuous, brownish pubescence; an-
tenn® slender, feebly serrate, piceous, the two basal joints pale; head rather
coarsely punctate, front triangularly flattened, the middle of the triangle elevated
in an umbone; thorax longer than wide, very little narrowed in front, sides
feebly arcuate, sinuate in front of the hind angles, which are slender and slightly
divergent, carina well marked, but short; disc convex, a median impression
reaching the base and very nearly the apex ; surface moderately coarsely punc-
tate in front and at sides, smoother at middle and near base; elytra oblong-oval,
wider slightly behind the middle, humeri rounded, disc convex, deeply striate,
strire punctate, intervals convex, moderately closely punctate; prosternum trans-
versely Impressed, rather finely punctate behind the groove, very coarsely in
front, the lobe moderately prominent, subtruncate; propleurje opaque, slightly
rugulose, coarsely sparsely punctate; epipleurte pale ; abdomen closely punctate
with coarser punctures intermixed, especially near the sides; legs rufo-testace-
ous, the tarsi piceous. Length 6.5 mm. ; .26 inch.
Very close to Sanborni, and possibly only an Arctic form of it.
The pubescence of the prosternal lobe seems to have been rather
exaggerated in importance and extent, as all the species of the pres-
ent and the ahbreviatus groups have a slight pilosity in that portion
not by any means dense, and often lost by abrasion.
I owe to Dr. Sahlberg the privilege of examining a typical speci-
men. Occurs in the vicinity of St. Lawrence Bay extending to Port
( 'larence on the American coast.
NORTH AMERICAN COLEOPTERA.
Group ABBREVIATUS.
Prosternal sutures straight, nearly parallel. Maxillary palpi
moderate in length, the last joint triangular, truncate at apex. Legs
not long, tibiie not spinulose externally, terminal spurs small. Thorax
with median line more or less impressed, the basal incisures feebly
distinct, hind angles, at most, but little everted, the carina not long.
Surface pubescent. Body winged.
The group here defined is with difficulty separated by description
from the one preceding, but the more convex form, pubescent sur-
face and less prominent hind angles seem sufficient.
The species composing the group occur in the Arctic regions of
both continents, extending southward in the more northern jiortions
of the temperate region, and along the mountain ranges in the
higher altitudes still more to the south.
In consequence of the wide distribution of the species and the
varied climatic influences to which they are subjected, a great amount
of variation has been produced. This range of distribution is from
Labrador on the east to northern California on the west, and in the
centre of the continent extending southward along the Rocky Moun-
tains to New Mexico, thence northward in every part of British
America to the extreme of the Alaskan peninsula.
In the great quantity of material examined I have not been able
to separate more than three species :
Scutellura conspicuously clothed with pale pubescence, that of the elytra some-
what scale like.
Thorax narrowed in front in its apical two-thirds, sides often obtusely suban-
gulate in front of the angular sinuation ; elytra with a denser spot of
pubescence near the apex abbreTiatiis.
Thorax arcuate near the apex only, the sides thence nearly straight ; elytra
without spot of denser pubescence near tip impressicollis.
Scutellum sparsely punctate and smooth, with scarcely any pubescence ; surface
simply sparsely pubescent; thorax usually very sparsely punctate, the
median impression very indistinct lioctiirniis.
C. abbreviatus Say. — Oblong, moderately convex, piceous, with greenish
bronze surface lustre, sparsely clothed with yellowish cinereous pubescence,
somewhat scaly in appearance, forming a conspicuous elongate space on the ely-
tral declivity ; anteun® feebly serrate, either entirely piceous, or with the basal
joints paler; head coarsely not closely punctate, the frontal margin scarcely
distinct from the clypeal ; thorax slightly broader than long, narrowed in front,
sides scarcely arcuate, but obtusely subangulate behind the middle, then sinuate
in front of the hind angles, these acute but not slender, scarcely divergent, cari-
nate ; disc convex, with a median impression usually extending from base to
apex and deeper behind, ba.sal incisures feeble, surface shining, moderately

(>EO. H, HORN, M. D,
closely, not coarsely punctate, pubescence somewhat brownish ; scutellum rather
densely clothed with paler yellowish hairs ^ elytra a little wider than the thorax,
widest one-third from base, humeri rounded, sides arcuate, gradually narrowed
in apical two-thirds, but obtuse at tip; disc convex, striate; strife all punctate,
intervals flat, moderately closely and finely punctate; body beneath piceous,
finely fulvo-pubescent, epipleurm usually paler; prosternum sparsely punctate at
middle, at sides intermixed and finely pubescent, the lobe very coarsely punc-
tate, moderately prominent; propleurm o])aque, finely and closely punctate
metiisteruum moderately closely punctate with intermixed punctures; abdomen
very finely and closely punctulate, the punctures unequal; legs rufo-testaceous,
the femora usually darker. Length 5.25—6.5 mm. ; .21 — .26 inch.
'riiis species varies in color from piceous black to brown, the elytra
being often quite pale. It may also vary in the form of the sides
of the thorax, the subangulation being scarcely evident in some
(lacmtris), but the thorax is always narrowed in its apical two-thirds.
The strife of the elytra may vary in sharpness, and their punctures
are sometimes scarcely evident on the disc.
The spot of pale pubescence near the apex is quite characteristic,
and its distinctness is not due to the abrasion of the rest of the sur-
face. In well preserved specimens the greater portion of the elytral
pubescence is finer and more brown, consequently less distinct.
No special sexual characters have been observed.
(Occurs from Nova Scotia westward through Massachusetts, New
York, Canada, Hazleton, Pa. (Dietz), to Oregon and Alaska.
C. iiiiprcssicollis Maun. — Oblong, moderately convex, piceous or brown-
ish, the elytra paler, surface slightly feneous, the pubescence sparse, pale brown-
ish, rather dense and fulvous on the scutellum; antenufe feebly serrate, piceous.
the basal joints paler ; head coarsely, moderately closely punctate, the frontal
margin scarcely elevated ; thorax scarcely wider than long, sides nearly straight,
arcuately narrowed near the front, a faint trace of a sinuation near the ungles,
these acute, scarcely at all divergent; the carina feeble, basal incisures distinct:
disc convex, the median channel distinct from base to apex ; surface moderately
closely punctate and (for this group) rather coarsely, pubescence fulvous ; scu-
tellum rather closely pubescent; elytra oblong-oval, widest near the middle, the
humeri rounded; disc convex, moderately deeply striate, strife all punctate, in-
tervals flat, rather closely punctate and posteriorly slightly asperately ; body
beneath piceous, finely pubescent and subopaque, epipleurfe paler; prosternum
sparsely punctate, more coarsely in front and more finely at the sides ; propleurte
opaque, with dense fine punctures, with coarser intermixed ; metasternum finely
indistinctly punctate, punctuation double; abdomen densely finely punctate,
with coarser punctures intermixed at the sides; legs rufo-testaceous. femora
darker. Length 5 — 6 mm. ; .20 — .24 inch.
This species superficially resembles abbreviatus, but the form of the
thorax and the absence of the spot of pubescence near the apex will

distinguish it. It will be observed in abhreviatus that the sides of
the prosternum have a well marked, fine silken pubescence, but in
this there is no such character.
In one of the specimens before me the elytra are paler at apex.
While I have not seen a type of this species I am quite sure that
the forms examined are similar to the unique described by Manner-
heim.
Occurs in Alaska, Oregon, Hudson’s Bay Territory and Colorado
(rare).
C. noctnrnus Esch.— Oblong, moderately convex, color variable, surface
shilling and with slight aeneous lustre, sparsely pubescent; antennae feebly ser-
rate, piceous, the basal joints often paler; head coarsely, not closely punctate,
frontal border feebly elevated ; thorax as wide as long, slightly narrowed in
front, sides arcuate, widest at middle, a slight sinuation in front of the hind
angles, these feebly everted, distinctly carinate, disc moderately convex, median
impression feeble, rarely visible in front of the middle; surface finely, sparsely
punctate; elytra oblong, a little wider at middle than the thorax, humeri ob-
tusely rounded, striate, striae all punctate, intervals flat, or slightly convex near
the base, sparsely finely punctate; scutellum sparsely punctate, scarcely at all
pubescent; body beneath paler than above, the epipleurae especially so; proster-
num very sparsely punctate, even on the lobe, sparsely cinereo-pubescent at the
sides, the lobe moderately prominent; propleune opaque, closely and very finely
punctate with coarser punctures intermixed ; metasternum and abdomen with
fine, indistinct punctures, moderately closely placed, with slightly larger punc-
tures intermixed; legs rufo-testaceous, femora always darker. Length 4 — 5.5
mm. ; .16 — .22 inch.
A variable species, widely spread over the northern part of the
continent, and with an unnecessary amount of nomenclature, the
result of local or climatic variation. A few varieties seem to deserve
mention.
Var. noetvrniis Esch. — Larger in size, piceous black, with teneous
surface lustre. The double punctuation of the abdomen scarcely
evident, except at the sides. The hind angles of the thorax are not
paler than the disc. Alaska, Oregon, California, Nevada.
Var. lucidulus Mann. — Smaller than nocturnus, and with rather
paler surface and less distinct leneous surface lustre. The hind an-
gles of the thorax are usually paler. The punctuation of the under
side of body is more distinct, and its double character more evident.
Of this form fallax Mann, and vestitus Mann, are merely individual
variations. Alaska, Hudson’s Bay, New Hampshire.
Var. bicolor Esch.— Still smaller, the hind angles of the thorax
and the elytra castaneous, with very feeble metallic surface lustre.

GEO. H. HORN, M. D.
Punctuation of under side coarser, its double character very evident.
Of this scarificatus and limhatus Mann, are feeble varieties, and pi-
cescens Lee. a synonym. Alaska, Oregon, Hudson’s Bay, Dacota,
Idaho, Utah, Montana, Colorado, New Mexico, Lake Superior,
Canada, Labrador, New Hampshire.
On comparing these forms with abbreviatiis and impressicollis, it
will be observed that the vestiture is finer and sparser, the scutellum
nearly glabrous. The thorax is always more sparsely and finely
punctured. The form is also less convex and more elongate.
Candeze states (Mon. iii, p. 68) that riparius Fab. occurs in the
polar regions of our continent. I have not seen any specimens that
I am willing to refer to that species, although some of the forms of
iuciduhis have the dorsal striie so feebly punctured that they might
l)e considered smooth. The study of the material before me leads
to the thought that all the species from the Arctic regions of both
continents need a renewed study with a larger number of specimens
than seems to have been used.
Group SQUALIDUS.
Prosternal sutures straight and parallel, or very slightly conver-
gent posteriorly. Maxillary palpi not prominent, the terminal joint
triangular. Legs slender and moderately long, the tibiae not spinu-
lose, the terminal spurs small and inconspicuous. Form oblong,
much depressed ; surface opaque, densely punctured, sparsely pubes-
cent. Body distinctly winged.
This group is represented in our fauna by three species, and a
fourth (depres-nis) from Siberia should probably be referred here.
The flattened form and opaque surface are repeated in the driaialus
series, but these have the strongly arcuate prosternal sutures.
The three species are as follows ;
Antennfe and legs always pale; under side of body finely pubescent with longer
scale-like hairs sparsely scattered sqiialitlus.
Antennae and legs piceous, sometimes the tibije are pale; vestiture of under side
uniform.
Surface very opaque liiiiebris.
Surface slightly aeneous plaiiatus.
C’. squalidus Lee. — Oblong, piceous black, opaque, sparsely clothed with
very short brownish pubescence, with silken yellow sparsely intermixed : head
coarsely, not closely punctate : antennse not reaching the hind angles of the
thorax, feebly serrate, joints all longer than wide, the eleventh but little longer
than the tenth ; thorax longer than wide, distinctly narrowed in front, sides
regularly arcuate, sinuate in front of the hind angles, these slightly divergent,
NORTH AMERICAN COLEOPTERA.
11
acute, distinctly carinate; surface moderately closely, but not densely punctate^
very evidently lonfiitudinally strigose ; disc feebly convex, a distinct basal in-
cisure opposite the fifth stria; elytra slightly wider posteriorly than the thorax,
humeri oblique, sides feebly arcuate, more so in the J ; disc sub-depressed,
striate, striae punctured, more coarsely at sides, especially near the humeri; in-
tervals flat, rather closely punctate; prosternal lobe long, its apex with a feebly
beaded edge and without a transverse impressed line posteriorly ; surface coarsely,
not closely punctured, feebly pubescent, propleurse opaque, coarsely sparsely
punctate and distinctly pubescent; metasternum and abdomen sparsely coarsely
punctate, with extremely fine punctuation closely placed between them, the
vestiture of pale brown, fine pubescence with intermixed golden scale-like hairs.
Length 7.5 — 8.5 mm. ; .30 — .34 inch.
The male is more slender and parallel than the female, but shows
110 other differences.
Occurs in California at San Jose and vicinity.
C. funebris Cand.— Oblong, depressed, black, opaque, finely pubescent;
legs piceous, sometimes with the tibise paler; head coarsely and moderately
closely punctate; antennae piceous, feebly serrate, the joints all longer than
wide; maxillary palpi not prominent, the last joint triangular; thorax a little
longer than wide, scarcely narrowed in front, widest at middle, sides regularly
feebly arcuate, sinuate in front of the hind angles, which are acute, slightly
divergent and with a short carina; disc feebly convex, a distinct incisure each
side of base; surface very densely punctured and without strigosity; elytra a
little wider than the prothorax, the sides nearly parallel, narrowed at apical
third, striate, strife punctured, intervals flat, closely punctate and quite rugous
at base; prosternal lobe moderately prolonged, its edge distinctly beaded and
with a deeply impressed marginal line and another transverse line of variable
distinctness posteriorly, coarsely and closely punctate in front of the transverse
line, more finely posteriorly; propleur® very opaque, very scabrous ; metaster-
num and abdomen closely finely punctulate, but not opaque, finely cinereo-pu-
bescent. Length 7.5 — 8.5 mm. ; .30 — .34 inch.
This species is more opaque and blacker than either of the other
species, while the punctuation of the thorax is dense and simple, not
strigose. The sculpture of the metasternum shows but few coarser
punctures and these near the middle, while the abdomen is entirely
free of them. The legs may be entirely piceous, or have the tibise
somewhat paler. There is absolutely no surface lustre in this species.
Occurs in California and western Nevada.
C. planatus Lee.— Oblong, nearly parallel, depressed, black, with faint
bronze tinge above, beneath opaque; antenufe black, a little longer than the
head and thorax, feebly serrate, joints all longer than wide; head coarsely and
moderately closely punctate; thorax distinctly longer than wide, widest slightly
behind the middle, not narrower in front, sides feebly arcuate, sinuate in front
of hind angles, which are slender, acute and slightly divergent, distinctly cari-
nate ; disc feebly convex (basal incisures distinct), coarsely, not densely punctate.

except near the front angles, punctures slightly strigose; elytra scarcely wider
than the thorax, parallel or slightly wider behind 9- humeri rounded; disc
striate, strite punctured, intervals flat, transversely wrinkled, irregularly triseri-
ately, subinuricately punctate ; prosterual lobe moderately prominent, the edge
with distinct bead, a transverse impressed line posteriorly in front of which the
lobe is densely coarsely punctate, then for a short distance sparsely punctate,
followed by a coarse, denser punctuation, with finer punctures intermixed;
metasternum coarsely punctate, closely near middle, more sparsely laterally, the
intervals finely closely punctate; abdomen closely, finely punctate, with scat-
tered larger punctures more numerous in front and on the apical segment.
Length 7.5 — 10 mm. ; .30 — .40 inch.
In well preserved specimens the pubescence of the upper surface
is short and inconspicuous; beneath very fine cinereous or fulvous.
This is the only species of the group with a faint bronze surface,
consequently less opaque than squalidvs or fmiebris. AVhile closely
related to the latter the punctuation of its upper surface is less dense,
the antennae longer, and the punctuation of the under surface more
intermixed and coarser.
The name given to this species was previously made use of by
Eschscholtz, but that being identical with hyperboreus, and the name
consequently suppressed, there seems to me no great objection to its
use for the present species.
Occurs in western Pennsylvania, New York and Canada, White
Mountains (Austin).
Group STRIATULUS.
Prosterual sutures arcuate and convergent behind. Maxillary
j)alpi not prominent, the last joint elongate triangular. Thorax
densely punctured and opaque, with, at most, a smooth median line,
base without incisures, carina of hind angles short. Elytra striate,
equally at the sides. Legs slender, the tibial spurs small. Form
depressed. Body winged.
The only species composing this group resembles a diminutive
planatm, but differs from that group by the form of the prosterual
sutures. The peculiar sculpture of the thorax in the choris and
Melsheimeri groups will prevent its being placed with them, the
perplexm series is convex, shining and ornate, while the tumescens
group is convex without ornamentation.
C. striatulus Lee. — Obloug, subdepressed, piceous black, opaque, finely
cinereo-pubescent; legs pale, the femora darker; antennae slender, black, feebly
serrate; head feebly convex, densely rugosely punctate; thorax a little wider
than long, narrowed in front, sides arcuate, slightly sinuate in front of the hind

lo
angles, which are stout, slightly everted, and with a short carina ; disc feebly
convex, densely finely punctate, the median line usnally smooth, but not always ;
elytra as wide as the thorax, humeri obtuse, sides nearly parallel for two-thirds
then arcuate to apex ; disc rather fiat, striate, equally from middle to sides, strife
punctate, intervals feebly convex, densely and finely punctulate, the surface
opaque; prosternum moderately closely punctate, more densely and finely at the
sides, the lobe short and subtruncate, the transverse impression distinct ; pro-
pleni’se closely finely punctate, not opaque ; metasternum and abdomen densely
punctate, a little more closely than the propleurse. Length 3 — 4 mm. ; .12 — .16 inch.
An easily known species by the group characters alone. In some
specimens the basal joints of the antenne are somewhat paler, but
these specimens have the under side somewhat paler also, and are
probably less mature.
The distribution of this species is rather remarkable. Originally
described from the Lake Superior region, it extends westward to
Oregon (Wickham) and northern California, eastward to Ohio
(Dury) and Allegheny, Pa (Hamilton).
Group CHORIS.
Prosternal sutures arcuate and convergent posteriorly. Maxillary
palpi moderately prominent, the last joint elongate triangular. Form
convex. Elytra deeply striate, more or less ornate. Thorax roughly
granulate, the median line usually finely elevated and smooth ; sur-
face more shining.
The species of this group seem naturally to fall together by the
very rough sculpture of the entire surface of the thorax. In the
dermestoides group the thorax is somewhat granulate in front, but
comparatively smooth posteriorly. To this group belong pxdchelhis
and sahxdieola, probably also curtus and alysidotus of the European
fauna.
The species known to occur in our fauna may be separated in the
following manner :
Apical margin of thorax truncate at middle.
Form gibbous, strongly arched when viewed laterally; carinse of hind angles
short ; entirely pale above cleliinibis.
Form normal, not very convex; cariufe of hind angles long; color black, or-
nate with yellow.
Antennae with three basal joints pale yellowish testaceous; legs always
entirely pale clioris.
Antennse piceous, very little, if at all, paler at base; legs with the femora
at least fuscous or piceous.
Elytra gradually attenuate in their posterior third.. exiguus.
Elytra not attenuate, ape.x obtuse oriiatiis.
Apical margin of thorax arcuate at middle, slightly prolonged over the head and
somewhat elevated Cliciillatus.

GEO. H. HORN, M. D.
€. «lellinibi« n. sp.— Oblong, narrowed posteriorly, rather strongly arched,
when viewed laterally, convex ; color above ochreous, the thorax ferruginous,
the head darker, elytra with vague fuscous spaces, often absent, beneath piceous
or brown, the last ventral segment and prosternal lobe pale; antennje entirely
pale, the outer joints scarcely longer than wide; head flat, granular; thorax
disti!ictly longer than wide, sides slightly arcuately narrowed from middle to
apex, nearly straight posteriorly, angles not divergent, the carina well marked,
but short, disc convex, the median line finely elevated and smooth ; surface
closely granular, not forming strig® ; elytra acutely oval, narrowed almost from
the base, humeri obliquely rounded; disc deeply striate, stri® rather wide,
coarsely not closely punctate, intervals convex, flatter at apex ; surface submu-
ricately punctate; prosternum closely and rather roughly punctate, distinctly
transversely impressed in front, the lobe moderately prominent, but obtuse ; pro-
pleur® closely punctate; metasternum rather short, coarsely and closely punc-
tate; abdomen densely submuricately punctate, becoming granulate on the last
two segments; legs pale yellowish testaceous. Length 4 — 5 ram. ; .16 — .20 inch.
This species is remarkable in its sharply arched form when viewed
laterally, as well as by the pale color of the surface. The elytra are
usually pale ochreous, but some specimens have a fuscous space on
the declivity of broadly crescentic form extending forward by its
outer angle parallel with the margin. The carina of the hind angles
is short, i.e., extending but little in front of the angles themselves,
while in all the other species of the group it extends nearly or quite
three-fourths to the ajiex.
Specimens were sent me many years ago by Mr. F. G. Sanborn,
collected by him in some numbers at Truro, Mass., a town on the
Cape Cod peninsula. It should occur in other places on the Atlantic
coast.
C. choris Say. — Form moderately elongate, distinctly narrowed posteriorly,
moderately convex, black, opaque, sparsely clothed with cinereous or golden
hairs, each elytron with an angulate sub-basal band, which extends to the
humeri, another transverse posteriorly yellow; anteun® slender, feebly serrate,
piceotis, the three basal joints pale yellowish testaceous; head feebly convex,
coarsely and closely granulate; thoi-ax very little longer than wide, sides feebly
arcuately narrowed in front, behind the middle nearly straight, or with a very
feeble sinuation in front of hind angles, these divergent, the carina long, ex-
tending fully three-fourths to apex ; disc convex, a smooth, median, elevated
line; surface rather coarsely and closely granulate, elytra widest in front of
middle, thence gradually narrowed to apex, humeri obtuse ; disc deeply striate,
stri® punctured, intervals convex, flat near apex, roughly, not closely punctate
and somewhat wrinkled ; prosternum closely punctate, but smoother in front;
two feeble transverse grooves in front, lobe moderately prominent, obtuse; pro-
pleur® more densely punctate, but not opsique; nietasternum and abdomen
densely and moderately coarsely punctate, but somewhat shining; legs pale
rufo-testaceous, the femora rarely slightly darker. Length 3 — 5 mm.; .12 -.20
inch.

The extent of yellow color in the bands is variable so that the
elytra may have more of that color than black, or vice versa. Speci-
mens of the former were those seen by Say. The normal style of
marking consists of a rather broad post-basal band with very sinuous
edges, crossing the suture and reaching the lateral margin ending a
broad extension to the humeri, behind the middle a transverse band
crossing the suture where it is broadest, not reaching the side margin,
with a posterior extension along the suture. The style of ornamen-
tation seems intermediate between that of exiguus and ornatus. The
elytra at tip have often a narrow pale border.
Occurs from the Middle States region westward to Indiana, and
south to District of Colundiia. A specimen collected by myself at
Fort Tejon does not appear to difler in any respect from those found
in the more eastern regions.
t-. exiguus Rand. — Moderately elongate, narrowed posteriorly, convex,
black, opaque ; elytra ornate with yellow ; antennae slender, piceous, three basal
joints fuscous, paler beneath : head flat, densely granulate, sparsely clothed with
short whitish pubescence ; thorax a little longer than wide 'J, , or as wide as long
9; sides feebly arcuately narrowing to the apex in front, posteriorly parallel
with a slight siuuation in front of the angles, which are acute and slightly di-
vergent, the Carina long, extending fully three-fourths to apex; disc convex,
closely granulate, the median line smooth and distinctly elevated ; surface
sparsely pubescent, more conspicuously at the hind angles; elytra widest a little
behind the humeri, then gradually narrowed to apex, humeri obtuse; disc rather
deeply striate, but less so near the apex, striaj punctate, intervals slightly convex
at base only, rather closely submuricately punctate, but smoother at apex,
sparsely cinereo-pubescent; prosteruum moderately closely punctate, but smoother
in front between the two transverse grooves, the lobe modeiate, but obtuse; pro-
pleurfe subopaque, densely punctate ; metasternum densely and rather coarsely
punctate; abdomen less closely and less coarsely punctate, last segment rufes-
cent; femora and tai-si piceous, the tibiae pale. Length 2.5 — 3 mm.; .10 — .12
inch.
This species has been the cause of some confusion, in which every
author who has treated of our Elateridte has had part. Described
originally by Randall, in 1838, under the above name it received a
second (guttatulus) from Mesheimer in 1845.
In 1853, Dr. LeConte, in his “ Revision of the Elateridie,” placed
exiguus and guttatulus, in part, in synonymy with imlchellus. When
the Melsheimer collection became accessible to him it was observed
that two species had been confounded, each represented by a single
poor specimen, one representing the present species, the other it was
thought might prove to be quadripustulatus of Europe accidentally
introduced in the cabinet. This latter specimen bore the typical
16
gp:o. h. horn, m. d.
label, ami was therefore assumed to be the type, notwithstanding the
fact that the very good description given by Melsheiiner points clearly
to exigmis. It is, therefore, without hesitation that I suppress gut-
iatnlus, absolutely, as a synonym, and for the species erroneously so
determined by LeConte the name Melsheimeri is proposed, and will
be found in its proper group.
Ur. Candeze simply followed in the lead of LeConte. A few
months ago (“ Entomological News,” 1890, p. 9) I continued the
same error through not having imldiellm for comparison. The sahu-
licola which had been sent me instead, serving alone for comparison,
led me to believe that our specimens fully met the requirements noted
by Fauvel (” Revue Ent.” 1889, p. 142).
On comparison of exiguus with puleheUus, it will be observed that
the former is more slender and convex, the elytral stride more dis-
tinct at apex and the elytra at tip piceous without the bifid space
seen in the other. The three basal joints of the antennae are pale
rufo-testaceous in pulchellus, piceous in exiguus, although paler be-
neath. The femora are also paler in the former species.
There seems to be a closer resemblance between pulchellus and
ehoris. They have similarly colored antennte and legs, but the elytra
are more roughly sculptured, the strite deeper at apex, and the bifid
spot absent in ehoris.
Occurs in the New England and Middle States; Massachusetts
(Blanchard) to District of Columbia (Ulke).
C. oriiatiis Lee. — Oblong, moderately convex, not attenuate posteriorly,
black, opaque; surface finely ciuereo-pubescent ; elytra either ornate, as in pul-
chellus, or with merely two small spots posteriorly or entirely black ; antenuse
slender, feebly serrate, entirely piceous ; front flat, densely granulately punctate ;
thorax a little variable in form, as wide as long ?, or a little longer than wide
"J, , narrowed in front, widest usually at or near the base, sides feebly arcuate in
front, behind the middle nearly straight and parallel, or with a faint sinuation
in some males, the angles not divergent, the carina extending nearly three-
fourths to apex, disc convex, the median line finely elevated and smooth ; surface
opaque granulate, the granules elongate and forming short strigae posteriorly;
elytra parallel, arcuately narrowed at apical third, humeri obtuse ; disc moder-
ately deeply striate, striae punctured, intervals flat, slightly convex, at base in
male, roughly punctate, more or less transversely wrinkled and rugulose, espe-
cially near the base; prosternura rather coarsely and closely punctate, especially
in front, two transverse impressions anteriorly, the lobe moderately prominent,
but obtuse; propleurae closely punctate, but not opaque; metasternum densely
and rather roughly punctate ; abdomen densely punctate, less coarsely than the
metasteruum. Length 3—5 mm. ; .12— .20 inch.

The males are more slender and rather more coarser than the
females, the thorax a little longer than wide and with a faint sinua-
tion in front of the hind angles, which are, however, not divergent.
There is considerable variation in color in the specimens before
me, and three varieties may he indicated.
Var. ornatus Lee. — The elytra have two yellow spaces. The an-
terior is transverse, post-basal, of irregular form, widest externally,
but not extending to the humerus nor margin. The posterior is
behind the middle, transversely oval, not reaching the side nor the
suture. The femora are piceous, the tibise and tarsi usually paler.
Var. colon Horn. — Here the elytral markings are reduced to a
small round spot on each side in the position of the posterior spot
of the jireceding variety. The legs may be as in ornatus, or entirely
piceous.
Var. rncerens. — Entirely black, without elytral markings. The
legs are nearly always piceous.
Occurs in California from San Diego northward in the central
valley, as well as along the coast region to Oregon (Blanchard).
C. ciicullatns n. sp. — Elongate oval, rather broader in proportion to its
length than usual in the genus, moderately convex, black; elytra with faint
bronze lustre; thorax cinereo-puhescent near the hind angles; elytra with ex-
tremely fine and short flavo-cinereous pubescence ; antennae slender, feebly ser-
rate, entirely piceous; head flat, closely punctate; thorax scarcely longer than
wide, sides straight posteriorly, gradually arcuately narrowed from middle to
apex, hind angles not divergent, the cariua extending in front of middle, apical
margin arcuate and prolonged over the head, deejtly sinuate near the front an-
gles; disc convex, without smooth median line; surface very coarsely granulate
but somewhat smoother on the declivity and near the hind angles ; elytra with
sides parallel, arcuately narrowed at apical third; apex obtuse, humeri obtuse;
disc moderately convex, striate, strife punctate, intervals slightly convex in their
entire extent and closely punctulate ; prosternum granulate in front, rather
finely punctate posteriorly, a faint transverse impression in front, the lobe short
and obtuse; propleurfe more finely and closely punctate than the sternum ; met-
asternuin a little more coarsely punctate; abdomen rather more finely and
densely ; legs piceous, the tibife and tarsi paler. Length 3.5 mm. ; .14 inch.
This species is easily known by the form of the apical border of
the thorax of which the middle forms a short lobe partly concealing
the head from above. On each side of this lobe is a rather deep
sinuation causing the front angles to be more acute and prominent
than usual.
Specimens have been examined from the Indian Territory ; Co-
lumbus, Texas (Schwarz), Utah (Ulke). A specimen has been seen
labeled Ohio, but the locality seems doubtful.

Group MELSHEIMERI.
Prosternal sutures arcuate and couvergeut posteriorly. Maxillary
palpi not promiiieiit, the last joint elongate triangular, the apex
rounded. Thorax asperate, or subgranulate in front, becoming
gradually quite smooth posteriorly, the base without incisures. Ely-
tra striate ; tibiae slender, spurs small ; surface usually shining, elytra
often ornate. Body winged.
A group of small species standing naturally betw^een the choris and
perplexus series. Its essential character is in the sculpture of the
thorax, the anterior portion being quite roughly or more densely
sculptured, and the basal portion quite smooth. Some curious sexual
peculiarities have been observed in some of them, of rare occurrence
in Elateridae, but by no means rare in Eucnemidae, consisting of tu-
bercles or pubescent spots on the first two ventral segments.
The elements composing the group are by no means homogeneous,
and might be again divided as the last three species have not that
very marked difference in sculpture of the thorax so well shown in
the others. As a whole, the group is known from the striatulus series
by its more convex form and the evident inequality of the thoracic
punctuation ; from the choris series by the opaque, granular thorax
of these ; the j)erplexus series has usually a sparsely punctate thorax,
and in any event the punctures are equal and equally disposed.
The following species are known to occur in our fauna :
Prosternal sutures widely double, smooth and grooved in nearly their entire
length ; thorax simply emarginate at apex when seen from above.
Antennae and legs pale; anterior tibiae of male not broader than in female,
the first ventral 'J, with a flattened space at middle enclosing a
tubercle Melsliei meri.
Antennae piceous, tip of first and the second and third joints paler; legs j)ale,
femora darker ; anterior tibiae of male nearly twice as broad as in
the female, the first ventral 'J, scarcely flattened, but with an oval
hairy spot quad rig uttatus.
Antennae piceous, paler at base; legs pale, femora piceous; anterior tibiae of
male not broader, the first and second ventrals of male with a tu-
bercle near the posterior border vatiriiius.
Antennae as in qiiadriguttatus, legs similar; anterior tibiae of male broader
than in female, but less marked; first ventral of male gibbous be-
tween the coxae, rather suddenly declivous posteriorly and fringed
with longer hair dermestoides.
Prosternal sutures very narrowly double, not grooved.
Carina of the hind angles of thorax extending to or beyond the middle of the
thorax.

Form subdepressed; thorax distinctly rugulose iu front; posterior coxal
plates obliterated externally.
Thorax simply emarginate in front; no ventral sexual characters in either
sex dispersiis.
Thorax sinuate each side at apex, the middle somewhat elevated and pro-
longed over the head ; second ventral of 9 with oval pubescent
spot gra<lariiis.
Form convex; thorax simply a little more coarsely punctate in front; pos-
terior coxal plates not obliterated externally ; sides of thorax sinuate
in front of hind angles tuniesceiis*
Carina of hind angles of thorax very short, not extending beyond the angles.
Piceous, faintly bronzed ; sides of thorax sinuate in front of hind angles,
these distinctly divergent iniisciilus.
Brownish opaque; sides of thorax straight posteriorly, the hind angles not
divergent diibitis.
It will be observed that two European species are introduced in
the table, the names in italics. These have been the cause of much
of the trouble experienced in identifying our species. On several
occasions specimens have come to me labeled dermestoides with quad-
riguttaim as a variety- Whether that is the view generally held in
Europe is hardly my province to investigate, but there is no question
in my mind that they are two well defined species easily separated
by the sexual characters of the male. I find no mention made of
the latter in any literature examined, they have even escaped the
acute observation of C. G. Thomson.
C. Melsheiiiieri n. sp.— Oblong, moderately convex, piceous black shining,
sparsely finely pubescent, each elytron with a humeral and subapical yellow spot;
antennae slender, feebly serrate, joints all longer than wide, ferruginous, joints
2-3 paler, basal joint darker; head slightly convex, punctate, somewhat asper-
ate; thorax wider than long, narrowed in front, sides arcuate, straight for a
short distance near base, hind angles broad, but acute, at tip, the carina extend-
ing finely three-fourths to apex ; disc convex, shining, asperately punctate in
front, gradually evanescent behind and quite smooth near the base, median line
distinctly smoother in front; elytra as wide at base as the thorax, humeri ob-
tuse, sides nearly parallel, arcuately narrowed at apical third, apices obtuse, disc
striate, strise extremely finely punctate, intervals slightly convex, sparsely mi-
nutely punctulate, the humeral spot small, rhomboidal, the subapical round •
prosternum sparsely punctate, more coarsely and closely in front, the lobe mod-
erately prominent, rather obtuse, prosternal sutures widely double, smooth,
grooved nearly their entire length, propleurje feebly shining, punctures fine and
close; metasternum moderately closely punctate, the last segment more densely
and opaque; legs pale rufo-testaceous. the femora slightly darker. Leno^th 2
2.25 mm. ; .08 — .09 inch.
The first ventral segment of the male has a flattened space at
middle, in the centre of which is a slightly elevated broad tubercle.
20
GEO. H. HORN, M. D.
The female has simjile ventral segments, the antenme a little shorter,
and the joints, consequently, relatively broader.
Superficially this species closely resembles quadriguitatus (tetra-
graphus), but the thorax is smoother, i. e., the roughness does not
extend so far j)osteriorly, and the median smooth line is shorter.
Thomsom states (Skand. Col. vi, }). 116) that in the male of tetra-
graphus the anterior tibije are inwardly dilated near the apex. No
such structure is seen in our species.
This species is the form for which Dr. LeConte retained the Mel-
sheimer name guttatnius, but I have elsewhere shown that the de-
scription applies accurately to that described previously as exigtms
Rand.
Occurs in the District of Columbia (Ulke) ; northern Illinois.
C. caiiriiiiis n. sp. — Oblong, moderately convex, piceous, slightly shining,
surface finely ciuereo-puhescent, each elytron with a small yellow spot at hu-
merus, a second suhapical, both indistinct; antennae slender, feebly serrate, en-
tirely piceous; head convex, a slight median impression posteriorly, surface
opaque, finely asperate; thorax a little broader than long, narrowed in front,
apex emarginate, sides parallel posteriorly, then gradually arcuately narrowed
to the front, hind angles stout but acute, the carina extended two-thirds to apex,
disc convex, median line somewhat smooth in front, surface asperately punctate
in front, finely and closely posteriorly ; elytra as wide as the thorax, humeri
obtuse, sides scarcely arcuate, apical third arcuately narrowed, apex obtuse, disc
striate, striae faintly punctured at the sides, intervals feebly convex, minutely
and moderately closely punctate ; prosternum finely not closely punctulate ;
a distinct transverse impression, anterior to which the punctuation is rather
coarse and rugose; lobe prominent, obtusely rounded in front, sutures widely
double, smooth and grooved, propleurae opaque, densely and very minutely punc-
tulate; metasternum and abdomen densely finely punctulate; femora piceous,
tibiae and tarsi testaceous. Length 2 — 2.5 mm. ; .08 — .09 inch.
The males have an oval flattened space in the middle of the first
v^entral segment enclosing a small tubercle, a second tubercle near
the margin of the second segment. Females are not known to me.
In a superficial comparison this species might be supposed to be
merely a Melsheimeri with sj)ots less distinctly marked, but here the
antennte are quite black and the male sexual characters different.
Occurs in the State of Washington.
CL «lis|>ersiis n. sp. — Oblong, moderately convex, piceous black, feebly
shining, sparsely and finely cinereo-pubesceiit, each elytron with a faint humeral
and subapical yellow spot, or without any ; autenuse slender, feebly serrate, en-
tirely piceous, or with joints 2-3 pale; head convex, sparsely asperately punc-
tate; thorax a little wider than long, apex emarginate, sides parallel for a short
distance posteriorly, thence arcuately narrowed to the front, the hind angles

broad, but acute; tbe carina extending two-thirds to apex, disc convex, median
line smooth in front, surface asperately punctate in front, sparsely punctate pos-
teriorly; elytra as wide at base as the thorax, but evidently narrowed from the
obtuse humeri, disc striate, striae finely puuctate, intervals slightly convex, finely
moderately closely punctulate; prosternum not closely punctate, a feeble trans-
verse impression in front, lobe obtusely prominent, coarsely and closely punc-
tate, the sutures very narrowly double, but not at all excavate, propleune less
shining, very minutely and densely punctulate; metasternum and abdomen
densely and finely punctulate ; legs testaceous, the femora darker. Length 2.25
mm. ; .09 inch.
The two specimens before me, which seem to be male and female,
exhibit no ventral sexual characters. One % from Washington has
entirely piceous antenme, a very faint humeral spot, the subapical
more distinct ; that from Nevada has no elytral spots, and the second
and third joints of the antennse pale. A third from Nova Scotia,
probably representing a distinct species, has the elytral spots well
marked as in Mehheimeri, and the three basal joints of the antennse
pale. In the absence of a male it is for the present placed with this
species.
Occurs in Nevada, Washington (and Nova Scotia?).
C. gradariiis n. sp. — Obloug, feebly convex, piceous-black, subopaque,
faintly bronzed, surface finely cinereo-pubescent, more evidently in the depression
near the hind angles; antenme black, slender, feebly serrate; front slightly im-
pressed, rather coarsely and roughly punctured ; thorax very little wider than
long, narrowed in front, sides posteriorly straight, in front gradually arcuate to
apex, apical border sinuate, slightly elevated at middle and prolonged over the
head, hind angles broad, but acute, the carina extending two-thirds to apex, disc
convex, asperately puuctate in front, more finely and smoother posteriorly; ely-
tra as wide at base as tbe thorax, humeri obtuse, sides feebly arcuate, apex ob-
tusely rounded, disc striate, strife punctulate, intervals feebly convex, punctulate ;
prosternum sparsely punctate, shining, a feehle transverse impression in front,
lobe not prominent, obtusely rounded, coarsely puuctate. prosternal sutures
simple, without trace of excavation, propleurfe subopaque, densely finely punc-
tulate; metasternum and abdomen closely finely puuctate; legs rufo-testaceous,
femora darker. Length 2 mm. ; .08 inch.
The male shows iio sexual characters on the ventral segments, the
female, however, has a finely pubescent, oval spot at the middle of
the second segment.
This species is the one I had thought identical with dermestoides,
but a closer examination shows it to be our equivalent, on this con-
tinent, of curtvs of Eurojie. The sinuation of the apical border of
the thorax, although sufficiently well marked in comparison with the
others of the group, is less distinct than in cncidlatus. The denser
silken pubescence of the hind angles of the thorax is rather a con-

precisely alike above and show no traces of pale spots.

tiiiuesceiis Lee. — Oblong, convex, facies robust, piceous-black, with
slight feneous surface lustre, sparsely cinereo-pubescent ; antennae either entirely
piceons, or with joints 2-3 paler; joints subtriangular from 4-10; head convex,
closely punctate ; thorax as wide as long, narrowed in front, sides rather strongly
arcuate, sinuate in front of the hind angles, which are acute, slightly divergent,
with the Carina extending nearly half to apex, disc convex, the median line
smooth, surface moderately closely punctate, a little roughened near the apex
only, gradually more finely posteriorly; elytra oval, widest a little behind the
middle, humeri obtuse, disc convex, striate, strife punctate, intervals slightly
convex near the base, sparsely punctate, more coarsely in front, the lobe obtuse,
propleurfe more closely punctate; metasteruum more coarsely punctate; abdo-
men more finely and closely punctate ; legs rufo-testaceous, the femora piceons.
Length 3 — 4 mm. ; .12 — .16 inch.
The prosteriial sutures, while doubled as usual in the group, are
very narrow, although in the female they are distinctly wider than
in the male.
The form of this species is quite that of a diminutive Cardiopho-
rus. The sculpture of the thorax does not have that marked rough-
ness seen in the preceding species. The posterior coxal plates are
not obliterated externally.
Occurs on the north shore of Lake Superior (LeConte), upper
Canada (Pettit) and New Mexico (Fuller); White Mountains
(Blanchard).
C. musculus Esch. — Oblong, convex, fscies robust, black, shining, surface
distinctly seneous, sparsely pubescent; anteniife piceous, slightly serrate ; head
convex, closely, subasperately punctate; thorax broader than long, very little
narrowed in front, sides strongly arcuate, sinuate near the hind angles, which
are acute, slightly divergent, and with a very short carina, disc convex, median
line smooth, surface closely and slightly asperate in front, gradually more finely
and s])arsely behind ; elytra oval, widest at middle, humeri rounded, disc convex,
striate, less deeply at sides, strife punctate, intervals slightly convex near the
base, moderately closely, but finely submuricately punctate, forming transverse
ridges near the base; prosternum sparsely punctate, a distinct transverse groove
in front, the lohe rather obtuse, propleurae similarly punctate; metasteruum a
little more coarsely punctate ; abdomen punctate similarly to the propleuraj, but
more densely; legs piceous, the tibife and tarsi paler. Length 2.5 — 3 mm.; .10 —
.12 inch.
The prosteriial sutures are not at all doubled in this species. The
carina of the hind angles of the thorax is here very short and in-
conspicuous, and might readily be passed unobserved. The posterior

Occurs in Alaska.
C. tliibius Horn. — Oblong, moderately convex, fuscous, feebly shining,
sparsely pubescent, hind angles of thorax paler; antennae slender, scarcely ser-
rate, fuscous, the three basal joints paler; head slightly flat, closely subasper-
ately punctate; thorax a little wider than long, narrowed in front, sides parallel
behind, arcuate anteriorly, the hind angles nearly rectangular, the cariua mod-
erate in length, disc convex, the median line smoother, surface closely punctate
and somewhat scabrous in front, gradually more smooth posteriorly ; elytra ob-
long, sides parallel, arcuate at apical third, humeri obtuse, disc striate, a little
less at the sides, strije relatively coarsely punctate, intervals flat, finely and
moderately closely punctate; prosternum sparsely punctate, transversely im-
pressed in front, the lobe short and obtuse, propleurfe finely and indistinctly
punctate; metasternum more coarsely punctate; abdomen very finely and mod-
erately closely punctate ; legs pale. Length 2 — 2.5 mm.; .08 — .10 inch.
The under side of body is notably paler than the upper, especially
on the sternal members and the epipleurte. The posterior coxal
plates are obliterated externally.
This species has the same general outline of body as in the Mel-
sheimeri series, but is more convex.
Occurs in Nebraska and Dakota (Ulke).
Group PERPLEXUS.
Prosternal sutures arcuate and rather strongly convergent poste-
riorly. Maxillary palpi moderately prominent, the last joint elon-
gate triangular. Elytra moderately deeply striate, ornate with yel-
lowish spaces. Form rather slender, convex. Thorax simply
punctate, not rugose, the median line not elevated nor smooth, with-
out basal incisures. Legs slender, tibial spurs very small.
Among the species with arcuate prosternal sutures, those of this
group are known by the striate and ornate elytra, with comparatively
smooth thorax. The only exotic species known to me as belonging
here is quadrijnistulatus Fab.
The species are separated as follows :
Thorax distiuctly narrowed iu front, at base as wide, or wider than at middle.
Antennfe and legs entirely piceous geiitilis.
Thorax coarctate at base and apex nearly equally, widest at middle, hind angles
slender, slightly divergent. Legs and three basal joints of the an-
tennse yellowish testaceous.
Elytral humeri obtuse, body with well developed wings, striae scarcely more
punctate than the intervals ; each elytron with two yellow spaces,
humeral and subapical sestivus.
Elytral humeri rounded, body very feebly winged, striae more coarsely punc-
tate than the intervals.
Each elytron with two yellow spots; thorax wider than long.
quadripustulatus.
Each elytron with a humeral spot only ; thorax distinctly longer than

Tlie European species is introduced in the table for the comparison
of its characters with the two in our fauna most closely allied to it.
C’. soiililis Lee.— Moderately convex, piceous, feebly shining, clothed with
tine flavo-cinereous silken pubescence, each elytron with an arcuate humeral
oblique yellow stripe and a short transverse one behind the middle; antennse
slender, ])iceous, feebly serrate, joints all longer than wide; head vaguely longi-
tudinally impressed, finely and moderately punctate, slightly scabrous; thorax
as broad as long, narrowed in front, sides anteriorly feebly arcuate, nearly
straight at basal fourth, the hind angles stout not divergent, tipped with yellow,
the Carina extending nearly to middle, but very feeble in front, disc moderately
closely finely punctate, the median smooth line very feeble, the pubescence ir-
regularly arranged, giving a holosericeous appearance; elytra as wide at base as
the thorax, humeri obtusely rounded, disc feebly arcuate, gradually narrowed
from base, disc deeply striate, striae closely punctate, intervals convex, densely
punctulate, somewhat scabrous near the base; prosternum sparsely punctate, a
little more coarsely in front, with two vague transverse impressions, the lobe
obtusely rounded with narrowly beaded margin, propleurm a little more closely
punctate than the sternum, shining ; metasternum and abdomen a little more
coarsely punctate than the prosternum, the apical segment somewhat roughened.
Length 3-4 mm.; .12— .16 inch.
In the male the form is more slender, and, contrary to what has
been noticed elsewhere in Elateridte, the elytral intervals are less
convex. The hind angles are also very slightly divergent. The
frontal impression may be vaguely triangular.
The yellow humeral lunule of the elytra is, in form, vei*y like the
same mark in Cicindela. The legs are jticeous, but sometimes the
tibite and tarsi are paler.
Frotn either of the species of this group this differs in having the
thorax broadest at base, the antenme and legs piceous.
Occurs in Nebraska (Ulke), Wyoming and Washington (Morrison)
C. sestivns Horn.— Oblong, moderately elongate and convex, piceous, basal
joints of antennse, hind angles of thorax, legs, a humeral and subapical spot on
each elytron yellowish testaceous, surface moderately shining, sparsely pubes-
cent; antennte feebly serrate, joints slender; front rather flat, head vaguely
punctate and slightly rugulose ; thorax not longer than wide, slightly narrowed
in front, widest slightly in front of middle, sides arcuate, distinctly sinuate in
front of the hind angles, which are slender, acute and distinctly divergent, the
Carina not prolonged, disc moderately convex, not closely punctate, the median
smooth line feebly evident posteriorly; elytra as wide at base as the thorax,
humeri obtuse, sides feebly arcuate, disc striate, strife punctate, intervals slightly
convex, not closely punctulate; prosternum sparsely finely punctate, vaguely
transversely impressed, the lobe short and truncate, propleur® more coarsely and
punctate than the prosternum at middle, shining; mesosternum punctured simi-
larly to the propleui-fe, the abdomen a little more finely. Length 4 — 5 mm. ;
.16 — .20 inch.

In this species tlie elytra are colored very like gentilu. The more
striking differences between it and the others of the group are suffi-
ciently detailed in the table.
Occurs in Missouri ; collected by Dr. S. V. Summers, Ohio (Blan-
chard).
C. perplexiis Horn. — Moderately elongate and convex, piceous-black,
shining, sparsely pubescent, three basal joints of the antennse, legs and a humeral
spot reddish yellow; antennse slender, feebly serrate; front rather flat, sparsely
punctate; thorax distinctly longer than wide, nearly equally narrowed at base
and apex, widest a little in front of middle, sides arcuate, distinctly sinuate in
front of the hind angles, which are small, acute and distinctly divergent, the
Carina distinct, disc convex, sparsely but equally punctate, median smooth line
distinct; elytra elongate oval, widest at middle, humeri rounded, the disc striate,
strise rather deep and coarsely punctate, the intervals convex, shining and very
sparsely punctulate ; prosternum transversely impressed in front, the lobe short
and obtuse, surface sparsely finely punctate at middle, more distinctly at the
sides, propleura*, shining, a little more coarsely and less closely punctate than the
sternum; metasternum a little more coarsely and closely punctate; abdomen
more finely than this. Length 2.75 — 3.5 mm. ; .11 — .14 inch.
This species resembles that variety of quadripmtvlatus in which
the humeral spot alone is present, but it differs in having the thorax
very obviously longer than wide, the elytral striie more coarsely
punctate, and the intervals smoother. The hind angles of the thorax
are sometimes tipped with yellow, but this is by no means frequent.
The body is very feebly winged.
Occurs in the District of Columbia, where it has been collected
abundantly, at times, by Mr. Ulke.
Group PECTORALIS.
Prosternal sutures arcuate, convergent posteriorly, nearly twice as
widely separated at the apical angles as at the coxae. Maxillary
palpi not prominent, the last joint triangularly oval. Legs slender,
the tibial spurs minute. Form at least moderately convex, body
winged. Elytra either not at all striate, or those near the suture
alone indicated faintly. Thorax without basal incisures, a smooth
median line variably present.
This group is equivalent to the second division, A A, indicated in
the Monograph of Candeze. Those occurring in our fauna separate
very naturally from the exotic forms by having the carina of the
hind angles of the thorax short, while in those the carina is pro-
longed nearly or quite to the anterior angles.

The species known to inhabit our fauna may be separated by the
following table.
Elytra faintly striate at middle, the striae distinctly impressed in the basal de-
clivity; antennae and legs piceous; surface shining, faintly aeneous.
restrictiiliis.
Elytra absolutely without striae ; antennae and legs pale.
Surface moderately shining, the punctuation extremely indistinct; each ely-
tron with an oblique yellow band at middle, not reaching the suture and
an oval apical spot obliquatulus.
Surface subopaque, the punctuation very distinct, especially on the thorax;
color very variable, from yellowish testaceous to piceous, with intermediate
maculate forms poctoralis.
The species of this group ai’e snmll, some of the forms of pectoralis
being the smallest Elaterides in our fauna.
C. restrictulus Mann. — Oblong, moderately elongate and convex, piceous,
shining, very sparsely pubescent ; antennae piceous, longer than the head and
thorax, slender feebly serrate, joints all longer than wide ; head slightly concave,
not closely punctate ; thorax slightly longer than wide, widest at middle, slightly
narrowed in front, sides arcuate, sinuate in front of the hind angles, which are
slender, acute, divergent and carinate, disc convex, finely not closely punctate,
the median line faintly smoother ; elytra oblong oval, widest at middle, humeri
rounded, disc moderately convex, very faintly striate near the middle, the striae
impressed in the basal declivity, at the sides entirely obliterated, surface moder-
ately closely punctate, except near the apex ; prosternal lobe short, mouth ex-
posed, the sternum moderately convex, sparsely punctate at middle, more closely
near the sides, propleurse shining, moderately closely punctate; metasternuni
and abdomen similarly punctate, not (dosely nor coarsely ; legs piceous, the tibiae
and tarsi sometimes paler. Length 3.5 mm. ; .14 inch.
In the male the last ventral segment is bisinuately truncate with a
median tooth, the same segment of the female is similarly truncate,
but in a less pronounced manner.
This species is described in the Monogra])h of Candeze as musculus
Mann., but a comparison of the original descriptions will show that
Dr. Candeze had restrictulus and not the other before him. Besides,
a type of muscuhis is in the LeGonte collection from Mannerheim.
The measurement given by Candeze is also incorrect foi' either spe-
cies, while its position among the striate species is certainly mislead-
ing. The form of the last ventral segment is not found in any other
species in our fauna. In habitus the species resembles Oedostethns
femoralis, but in the latter the stride are more distinctly impressed,
although obliterated at the side, and the claws have the basal half
dilated.
Occurs in Alaska (Mannerheim, Ulke) and in the White Mountain
region of New Hampshire (Blanchard).

obliqiiatiilus Mels. — Oblong, moderately convex, pi ceo us, thorax some-
what paler in color, very sparsely pubescent, antennfe and legs testaceous; an-
tennse slender, feebly serrate, joints all longer than wide; head sparsely punc-
tate ; thorax a little wider than long, slightly narrowed in front, widest at middle,
sides regularly arcuate, sinuate in front of the hind angles, which are small,
acute, and very slightly divergent, the carina fine, and. when seen from above,
directed nearly straight to the front, disc moderately convex, sparsely equally
punctate, the median smooth line very faint; elytra slightly wider than the
thorax, humeri very little oblique, sides regularly arcuate, widest at middle, disc
entirely without striae, more sparsely and finely punctured than the thorax, color
piceous, on each elytron an oblique yellowish band reaching the margin, but not
the suture, an oval apical spot of variable size also yellow ; prosternum sparsely
punctate, and with two transverse impressions, the lobe moderately prominent,
but obtusely rounded in front, the border finely beaded, propleurae shining, more
sparsely and finely punctate than the sternum ; metasternum minutely and in-
distinctly punctate, abdomen more densely and coarsely. Length 2.25 — 2.75 mm. ;
.09 — .11 inch.
Usually the underside of the body is much paler than the upper,
especially in the prothorax and the elytral epipleurie. The color
and markings seem to be very constant, and vary but little beyond
that caused by varying degrees of maturity.
The males have a small, densely punctured space at the middle
of the prosternum, usually more pubescent, but never as distinct as
in pectoralis.
Distributed from Canada aud the New England States southward
to Virginia and westward to Iowa.
C. pectoralis Say. — Oblong, feebly convex, subopaque, sparsely finely pu-
bescent, color variable from entirely yellow to entirely piceous ; antennte slender,
feebly serrate, joints all longer than wide, yellowish testaceous ; head moderately
closely punctate, front fiat; thorax usually as wide as long, sometimes slightly
longer, slightly narrowed in front, widest at middle, sides arcuate, scarcely
sinuate in front of the hind angles, which are S7nall, acute, but not divergent,
the carina, when viewed from above, turned externally, disc very distinctly and
rather closely punctate, the median smooth line usually evident; elytra slightly
wider than the thorax, humeri slightly oblique, sides arcuate, disc without strife,
surface less distinctly punctate than the thorax; prosternum moderately closely
punctate, transverse impression not well marked, the lobe moderately prominent,
subtruncate in front, propleurfe- punctate similarly to the sternum ; metasteruum
punctate similarly to the prosternum, the abdomen much more finely and densely.
Length 1.5 — 3 mm. ; .06 — .12 inch.
The males of this species have a small, but densely punctured
s]iot at the middle of prosternum from which arises a bunch of longer
pubescence. The pubescence is often absent, except in well preserved
specimens.
This species varies greatly in color, and has been given three
names in consequence. These varieties may be de.scribed as follows :
28
GEO. H. HORN, M. D.
Y nr. pectoralis iiiiy. — Entirely yellowish testaceous above and be-
neath. Specimens often occur with a transverse fuscous fascia behind
the middle of the elytra, which extends narrowly along the suture to
the apex.
This form occurs from Massachusetts to California and Texas.
Va.r.futilis Lee. — This does not differ from the preceding variety,
except in its smaller size and with apparently a slightly more rugose
thoracic sculpture. A subvariety occurs in Arizona entirely piceous.
'fhese latter are the smallest specimens seen (.06 inch).
Occurs at San Diego and Owen’s Valley in California, and also in
Arizona.
Var. inops Lee. — Piceous, elyti’a with an indefinite humeral yellow
spot, a short transverse band at middle adjacent to the lateral mar-
gin, these two sometimes united along the margin, a subapical yellow
space. Specimens often occur with a median discal space of the
thorax yellowish.
Occurs in California and Washington.
Var. . — Entirely piceous, and occasionally with the
legs darker than normal.
This is known to me from the extreme northwest, Washington,
although one from Iowa has merely slightly paler humeri.
From the localities given this seems to be the most widely dis-
tributed of our species.

APPENDIX.
fflDOSTETHlTS Lee.
This genus does not seem to be generally known to collectors, so
that but few specimens have ever been sent me for determination. It
differs from Cryptohypnus in having the claws abruptly dilated at
basal half as shown in fig. 8, pi. 1. The prosternal sutures are
arcuate, but in a less degree than in the species of Cryptohypnus
with sutures.
Oe. femoralis Lee.. Revis. Elat. p. 489.
This is the only species known. It greatly resembles C. restrictuhis,
having the stride of elytra feebly distinct on the disc and obliterated
at the sides, the color and form being also quite similar. The max-
illary palpi are rather slender and similar to restrictulus.
It is known to me from Canada, westeim Pennsylvania and
Colorado.
.4KTHRACOPTERYX u. g.
Frontal margin not elevated, confluent with the edge of the cly-
peus. Antennte a little longer than the head and thorax, joints 3-10
feebly serrate, nearly equal in length, eleventh longer, second shorter,
first joint stout, nearly as long as the next two. Maxillary palpi
long, the last joint (of both palpi) cultriform, longer than the two
preceding joints together. Thoracic margin acute, when seen later-
ally nearly straight, terminating opposite the middle of the eye;
scutellum oval, slightly transverse. Elytra oblong, humeri obliquely
rounded, body apterous. Prosternal lobe rather short, the mouth
exposed beneath, the sutures straight, slightly convergent posteriorly,
tip of prosternum acute, flexed upward toward the body- Posterior
coxal plates abruptly dilated at inner third. Tarsi as long as the
tibije, the first four joints decreasing gradually in length and not
lobed, claws simple.
The above description briefly defines a form which it is by no
means easy to place. From the method of classification adopted by
Dr. Candeze, which assumes the form of the front as the character
of greatest primary moment, the genus should be referred to the
division Corymbitites and to the group Dirnites. From Dr. Can-
deze I have received the following note: “ For me there remains no
doubt, after a mature examination, that it can be placed in the
Dimites, where it will form a new genus related to Diadysis (of
Australia) and Asorno (of Patagonia) which I will hereafter j)lace
in the Diiuites.”
NORTH AMERICAN COLEOPTERA.
31
In a sentence immediately preceding he writes: “Its head is the
head of a Corymbitite, but the coxte !” Here is the point at issue.
The form of the posterior coxal plates, whether abruptly or gradu-
ally dilated internally seems to me a character of greater stability,
and therefore more reliable as a character than the form of the head.
Therefore, I must at this time differ from that learned entomologist,
and place it among the Cryptohypnites.
In the latter group we find species with the frontal margin scarcely
distinct from the clypeal and the labial palpi exhibiting a tendency
to elongate, especially in the last joint.
From Cryptohypnus the genus may be said to differ by the form
of the long maxillary palpi terminated by a cultriform joint.
Science owes to Mr. T. D. A. Cockerell the discovery of the spe-
cies on which the genus is founded, and both the generic and specific
names are due to his suggestion. Had it not been for the necessity
of quoting the letter of Dr. Candeze in order to explain why I dif-
fered from him, I would have preferred to have elaborated the notes
sent me by Mr. Cockerell to publish them under his name.
A. liieiiialis n. sp. — Oblong, parallel, moderately convex, piceous, slightly
shining, sparsely pubescent; antenme a little longer than the head and thorax,
piceous, feebly serrate, joints all longer than wide ; head sparsely punctate, front
rather flat, the frontal ridge not continuous across the front; thorax longer than
wide, apex feebly emarginate, widest one-third from apex, sides moderately
arcuate, slightly convergent posteriorly, feebly sinuate before the hind angles,
which are acute, not long nor divergent, distinctly carinate, disc moderately
convex, median line feebly impressed posteriorly, without basal incisures, sur-
face equally punctate, moderately coarsely, but not closely; elytra not wider
than the thorax in front, oblong oval, humeri very oblique, disc striate, strije
punctured, intervals flat, irregularly biseriately punctate and somewhat wrinkled,
especially at base ; prosternal lobe not prominent, irregularly arcuate in front,
the edge not beaded, surface coarsely not closely punctate, apical mucro very
oblique, propleurse less coarsely and less closely punctate; metasternum and
abdomen still less closely punctate and more shining, the last segment more
coarsely and closely ; legs piceous, tarsi usually paler. Length 6.5 mm. ; .26 inch

XEW SPEEIES AND MISt'EEEANEOES NOTES.
BY GEO. H. HORN, M. D.
The few new species described below are mostly of curious forms,
or of groups not previously represented in our fauna. Others have
interest in their relationship with Mexican forms, while several are
indicated as inhabitants of our fauna known previously from more
tropical regions to the south.
A few synonyms have been given which need no special comment.
PTEROSTICHUS Bon.
P. (Hyperphes) iiiaiiis n. sp.
This name is suggested for a species closely ailed to angushis, Imt
of rather less parallel form and somewhat larger size, and always of
darker color. The head is broader, and more distinctly narrowed
behind the eyes, which are larger and more convex. The thorax is
more distinctly narrowed behind from being somewhat more arcuate
in front. The basal impressions are deeper and longer, while the
basal marginal line is very short (in angustus extending across the
entire base). The elytra are more depressed, the sides more arcuate.
The under side does not present any essential differences. Length
10-12 min.; .-10-.48 inch.
In the male the hind trochanter is always two-thirds the length
of the femur, and sometimes slightly longer than that, the apex very
acute, while in angmtus the same member is rarely more than half
the length of the femur and obtuse at tip.
The essential differences from angustus are — larger size and less
parallel form, prothoracic impressions deeper and longer, basal mar-
ginal line here almost absent, except at hind angles, and finally the
form of the male hind trochanters.
Occurs in Washington, Nevada, and as far south as Placer County,
California.
P. (Hyperphes) caligaiis n. sp.
Very like angustus, but still more slender and elongate. Castane-
ous, shining, elytra very finely alutaceous ; head relatively larger,
frontal impressions moderately deep, optic prominences normally
large, the eyes very small ; thorax longer than wide, narrower at
base, sides very feebly arcuate, slightly sinuate in front of the hind
angles, which are sharply rectangular, median impression moderately
deep, extending to base and nearly to apex, basal impressions sitigle.
NORTH AMERICAN COLEOPTERA.
33
moderately deep, arcuate, liasal marginal line entirely absent; elytra
oblong, nearly 2mrallel, humeri slightly dentate, surface moderately
deeply striate, strije obsoletely punctate, intervals very slightly con-
vex ; beneath similar in color, abdomen finely alutaceous, indistinctly
punctate at sides in front. Length 10-11 mm. ; .40-.44 inch.
In the male the hind trochanter is about half as long as the femur
and obtuse at tip.
Two sjiecimens have been examined, taken by Mr. L. E. Rick-
secker at ISylvania, Cal.
This species is evidently closely related to longissimus Bates (Biol.
Cent. Am. i, p. 81, pi. iv, fig. 6), although that species is said to have
non-dentate humeri. Direct comparison will be necessary to indicate
the real differences, as it can hardly be supiiosed that an almost
blind species from middle California is identical with one from
Guatemala.
The two species above described constitute, with migustus, a small
group of Pterostichus, characterized especially by a very narrow,
almost parallel form. All have small eyes, although they vary in
size in the three species. Of the three itianis has the largest eyes,
and caligans the smallest.
The characters separating them may be tabulated in the following
manner :
Thorax witli two distinct linear basal impressions, the basal marginal line entire ;
hind trochanters of 'J, longer than half the femur and very acute at tip;
scutellar stria rarely well marked, often absent inaiiis.
Thorax with two basal impressions, the outer quite short, basal marginal line

Thorax with but one basal Impression, the basal marginal line entirely wanting;
hind trochanters of male as in angustus ; scutellar stria distinct. .caligaiis.
The last species resembles in a marked degree, small sj^ecimens

the middle; body beneath smooth, shining, prosternuin not margined at tip.
Length 6 mm. ; .24 inch.
This is the smallest species outside of some in the Cryobius series
known to me in our fauna. It has the general aspect of honedus,
although less convex, and somewhat more acute posteriorly. It may
be known from that species by the following j)oints :
Thorax punctate at base, without marginal line, basal impressions arcuate; striae
not punctate lioiiestiis.
Thorax smooth at base, marginal line entire, basal impressions straight ; striae
punctate, intervals erenate ISlaiiicliardi.
The unique before me was collected by Mr. F. Blanchard at
Highland, North Carolina.

D. cordicollis n. sp. — Form rather depressed, pieeous to castaneous in
color, shining, the darker specimens with a faint feneous lustre, anteunpe and
legs always paler. Head smooth, frontal impressions short, in some specimens
two punctiform fovese between the eyes; thorax rather more than half wider
than long, broadly cordate, sides arcuate and gradually narrowing to the base,
the hind angles entirely obliterated, disc feebly convex, smooth, rarely feebly
transversely wrinkled, basal impressions short, but rather broad; elytra subde-
pressed, oblong oval, strige fine not punctate, intervals slightly convex and
smooth , or flatter and feebly alutaceous 9, the usual rows of punctures on
the alternate intervals ; body beneath smooth, less shining than above, proster-
uum not margined at tip. Length 7.5 — 8.5 mm. ; .30 — .34 inch.
In both sexes there is but one anal puncture on each side. The
male is more shining than the female, and the elytral intervals more
convex. The last ventral of the male is more obtusely arcuate at

apex, that of the female being much more acute and slightly ele-
vated in an obtuse carina near the middle. The male has a few
squamules on the anterior tarsi. Tibiie straight in both sexes.
This species is the most depressed of any in our fauna, and has
the thorax much more narrowed behind, resembling a diminutive
Polpochile capitata. There is no depression of the lateral margin of
the thorax, as is usual in our heretofore described species.
Occurs from Fort Yuma eastward to Tucson, Ariz. (Wickham.)
I>. crassicollis n. sp. — Form robust, convex, piceous, shining, without
trace of metallic surface lustre; antennae, palpi, and usually the labrum, casta-
ueous; head impunctate, frontal impressions very short; thorax quadrate, a
little wider than long, slightly narrowed at base, widest one-third from apex
sides regularly arcuate, margin not depressed, hind angles obtusely rounded, disc
convex, median impression faint and short, basal impressions broad, but shallow
and vague; surface smooth, with a few longitudinal wrinkles at base; elytra not
wider than the thorax, sides feebly arcuate, disc convex, finely striate, stri® not
punctate, intervals smooth, very feebly convex, the inner sides of 3-6-8 with
the usual punctures fine and rather indistinct; body beneath slightly paler,
shining, prosternum not margined at tip, but with two (usually) prominent bris-
tles on each side; abdomen very sparsely punctate, coarser punctures on the
intercoxal process. Length 12.5 mm. ; .50 inch.
Although reasonably certain that both sexes are before me in the
live specimens examined, no well marked sexual difierences have
been observed. The last ventral segment bears two setie on each
side. The middle tibise are not longer than the anterior, are broader
toward the tip, slightly arcuate and beset on the outer side with short
spinules. The posterior tibise are also very slightly arcuate. The
anterior tarsi are not furnished with squamules.
This species is evidently very closely allied to acmopoides Bates
(Biol. Cent. Am. Col. i, p. 63), which is described as having the
elytra cupreous and the sides of the thorax straight and not arcuately
narrowing as in the present species.
It is the most robust and convex species in our fauna, quite unlike
our others, and resembling an Acinopus more nearly than Discoderus.
Occurs in southern Arizona.
AJV.4TRICHIS Lee.
This genus has been divided by Chaudoir (Ann. Fr. 1882, p. 322)
into Anatrichis and Oodiellus, the former represented by ouv nihuita,
the latter (which Mr. Bates very properly considers a synonym of
Oodinm Mots.) typified by mexicanus Chd. (1882) = piceus Mots.
(1864). In the paper above cited Chaudoir describes three addi-
3G
GEO. H. HORN, M. D.
tional species of Anatrichis, two from the East Indies, the third
Australian. Four species are referred to Oodiellns, one from Mexico
and three from Brazil. Mr. H. W. Bates describes as Anatrichis
two more from Mexico which must be referred to Oodiellns, whether
regai-ded as a section or a valid genus. The characters of the latter
genus are derived entirely from the mouth parts and do not seem to
be of sufficient moment for generic separation, as Mr. Bates has
remarked, an opinion in which I fully concur.
In his posthumous work Chaudoir fails to mention a character
of the male of Anatrichis observ'ed by LeConte (Trans. Am. Philos.
Soc. 1853, X, p. 391). The middle tibiae have on the inner side at
the lower third an emargination resembling somewhat that of the
front tibia. This character is not observed in the only male of
Oodinus examined. It would be interesting to know what value this
has, in addition to those given below, for the separation of Anatrichis
and Oodinus.
There is, however, one character more easily seen which will sepa-
rate the species of the two divisions without, to my mind, having
any greater weight than those u.sed by Chaudoir.
As far as can be gathered from descriptions the species separate
in the following manner:
Elytral strife distinctly punctate S. G. Aiiali'icliis.
Elytral strife fine and simple S. G. Oodinus.
The former is represented in our fauna by A. minuta Dej., with
shining, finely punctate surface, the basal impressions of the thorax
deep but short. The apex of the prosternum is distinctly margined.
The subgenus Oodinus is represented by two species.
Form more broadly oval than A. minuta, surface more opaque; first and second
elytral striae uniting at base, terminating together in an ocellate fovea ;
prosternum not margined at tip l>icea Mots.
Form oblong, recalling a diminutive Lachnocrepis parallela, surface shining;
strife all partly obliterated at base, an ocellate fovea near the end of the
second ; prosternum margined at tip obloiiga n. sp.
The genus Anatrichis is properly considered feminine in its termi-
nation by LeConte, Chaudoir and the Catalogus. Mr. Bates, how-
ever, appears to regard it as masculine from his specific names.

treniely fine and the basal impressions very shallow and vague; the elytral stria-
are fine and sliarp, without punctures, the intervals flat, minutely alutaceous,
the third with the tvvo dorsal punctures behind the middle; the prosternum is
obtuse at tip and without marginal line. Length 6 mm. ; .24 inch.
The specimen before me is a male. The first four joints of the
anterior tarsi are dilated as in viinuta, but the middle tibiae are simple.
Occurs in our fauna in southern Texas and Central America to
Santarem, in Brazil.
A. obloiiga n. sp. — Oblong, piceous-hlack, somewhat shining; antennse pi-
ceous, the three basal joints and palpi rufo-testaceous ; head without frontal im-
pressions, the surface extremely minutely alutaceous: thorax about one-third
wider at base than long, sides arcuately narrowing to apex, median line very
finely impressed, the basal impressions deep but short, surface minutel.v aluta-
ceous; elytra oblong, sides feebly arcuate, strife sharply impressed but not punc-
tate, not quite reaching the base, an ocellate fovea near the base of the second,
intervals flat, verv minutely, sparsely punctate and finely alutaceous, the dorsal
punctures of the third interval indistinct; body beneath more shining than
above, the prosternum with marginal line at tip ; legs castaneous. Length 6 mm. ;
.24 inch.
This species is evidently closely related to lougula Bates, and may
even be the same, although I can hardly apply his description of the
thorax to my specimen : “ transversim quadrate, antice paullo magis
quam postice angustato.”
The surface sculpture is so minute that a moderately high power is
required to detect the alutaceous structure and the elytral punctures.
One specimen 9 » Texas near the lower Rio Grande.
OODEN Bon.
From the description given by Chaudoir, in 1882, it seems that the
species known to us as texaims Lee. is the same as mexicanus Chev.
0. duodecimstriafm Chev. According to Chaudoir, who has ex-
amined types, this name should replace 0. Lecontei did. in our lists.
STEXOC'REPIS Chd.
A specimen in my cabinet collected near the lower Rio Grande
of Texas seems to be referable to S. chalcas Bates {chalcoclirous Chd.),
Biol. Cent. Am. Col. i, )i. 47. It is nearly as elongate as Lachno-
crepis, but with a form of thorax as in our Oodes s.s. The striie
are very distinctly punctate and the sides of the intervals crenate.
The under side of the body is iridescent, the sides of the metaster-
num with coarse punctures, the first two ventral segments at the
sides with very coarse punctures. Prosternum not margined at tip.
On the elytra the seventh stria is replaced by a row of extremely
indistinct fine punctures.
88
(iEO. H. HORN, M. D.
If the insect before me really represents S. chalcas, and of this I
have very little doubt, the genus seems to me intermediate between
(dodes s.s. and Lachnocrepis. With the former it agrees in having
the first foxir joints of the anterior tarsi of the male dilated and
papillose beneath, although the posterior tarsi are not pubescent be-
neath. The mode of dilatation of the tarsi is the same as in Lach-
)iocre])is.
It seems to me that Chaudoir was not true to his own methods in
uniting Stenocrepis, Stenous and Crossocrepis as sections under the
first name. If it be advisable to se[)arate any of them from Oodes,
it seems to me desirable to retain Stenocrepis apart, while the other
two could be very well united.
In Oodes s.s. the entire under side of the body is comparatively
smooth, in the others above mentioned the sides of the metasternum
and the metapleurse, and usually the sides of the first two ventral
segments are very coarsely punctate.
EUPHORTIC’US Horn.
E. occitleiitalis u. sp.
This name is proposed for a species occurring near Los Angeles,
Cal., resembling jm/6escens Dej., and differing in the following manner:
Surface more brilliantly aeneous. Elytral striae very faint, the punctures fine,
ronucl and rather distant, intervals flat, punctulate. Length 4 mni. ; .16 inch.
The punctures of the elytral stripe do not extend beyond the mid-
dle in either species, but in puhescens they are large and more closely
placed than their own diameters. On the other hand the fine punc-
tures of the intervals are sparser and less distinct in occidentalis than
\\\ puhescens. In the latter species the tibipe are always jialer than
the feuKji-a, in the former they are as dark as the femora.
PCECIEOEHRUK Bouv.
To this genus should be referred the species described by me as
Htethon errans.
Poecilochrus may be distinguished from Stethon by the straight
prosternal sutures. In both genera the metasternum has a short
groove limited by an elevated line begining at the inner side of the
middle coxae and directed backward in a straight line.
Dronueolus pnsillus Horn. — This species, while very unlike our
others, has a number of related forms in the Mexican fauna. They
nearly all have the |)rosternal sutures very finely grooved and the
NORTH AMKRICAN C0LE0PTJ:RA.
39
propleural triangle is in absolute union with the prosternuin, or very
nearly so. In facies they more nearly resemble Thambus than
Dromseolus.
I have already called attention to the fact that in Microrhagus
(Trans. Am. Ent. 8oc. 1886, p. 35) the pubescent fovea on the last
or penultimate segment was a sexual character. While the fact is
correct, I have wrongly attributed the possession of it to the male.
Since then the same character has been elsewhere observed, Enio-
mophthalrnus americanus, where the female has the fovea and the
male a small tubercle.
In the table of Microrhagus (Mon. des Eucnemides) under “23,”
p. 528, two series of species are separated, the one with femora
scarcely darkened, the other with them decidedly brown or nearly
black. Fortunately but three species are sepai’ated under the last
<livision, otherwise confusion might result, as the color of the legs, as
above defined, has no value whatever.
CLiADUS Bonv.
While this genus of Eucnemidm is not represented in our fauna,
belonging exclusively to the central American region, I have thought
it worth while to call attention to it, as but few interested in purely
North American entomology will see the illustration of the extra-
ordinary modification of the mouth parts published by me in the
“ Biologia Centrali-Arnericana.”
The accompanying illustration is the same as used in that publi-
cation, and shows the maxilla of the
right side uncovered by the removal
of the half of the mentum and on the
right side of the cut the remaining half
of the mentum. The maxillary paljms
is transformed into two long stalks
bearing ciliate branches. The labial
palpus is ])rimarily divided into four
branches, two of which, the first and
third, are again divided ; all with ciliate
branches. The ribbon-like prolonga-
tion behind the palpar modification is
a modified ligula. The two lobes of the
maxilla are sufficiently well shown in the cut and need no explana-
tion.
40
GEO. H. HORN, M. D.
The Utility of this modification in a family in which the mouth-
parts are otherwise quite constant is, for me, beyond explanation.
The Eucnemida3 seem to live their short lives by the ingestion of
liquid food, the juices of decaying wood and similar matters, so that
this modification may assist capillary action, although there does not
seem any reason why Cladus should be so provided and the closely-
allied Fornax not.
PAL,.«OXEi\lJS u. g.
This new generic name is suggested for a species described by me
some years ago as Cryptosto^na Dohrnii.
At that time I had seen no specimen of Cryptostoma, and the
failure to record several important characters in the Bonvouloir de-
scription caused me to refer my specimen to that genus. Through
the kindness of Mr. Ed. Fleutiaux I have been enabled to study a
specimen of C. spmicorne, and can now indicate the differences :
Paheoxenns. — Antennfe simple in both sexes, the last two joints
shorter, the terminal joint broader than long, squarely truncate, but
chisel-shaped on its terminal edge. Mesosternum oblique, broadly
grooved. Eyes longer in their vertical diameter and without dis-
tinct supra-orbital ridge.
Cryptostoma. — Antennse with a spiniform process from the base of
third joint % , or with a spine on the posterior side near apex of
first joint 9 , the terminal joint longer than the preceding and either
slender % , or very acutely oval at tip 9 . Mesosternum prominent,
the sides elevated, forming the usual receptacle for the tip of proster-
num. Eyes oval, very little longer vertically and with distinct
supra-orbital ridge.
PHEXGODES Latr.
I*. |»icicollis n. sp. — Head piceous black, deeply, arcuately impressed be-
tween the eyes, and longitudinally toward the clypeus, in front of the transverse
groove coarsely and closely punctate, behind it coarsely longitudinally strigose
and punctate; antennie not half as long as the body, piceous-black. the branches
fuscous, the basal joint yellow: eyes relatively small ; thorax about one-half
wider than long, apex arcuate, sides arcuate near the front, then parallel to base,
lateral explanate border moderate, disc moderately convex, a round fovea each
side near the apex, a slight longitudinal impression at middle nearer the base,
surface shining, rather finely not closely punctate, more distinctly near the sides,
sparsely flavo-pubescent, color piceous, with the entire limb narrowly testaceous;
scutellum piceous; elytra yellowish testaceous, gradually fuscous toward the
apex ; abdomen yellowish testaceous, the segments piceous along their anterior
b(!rder, beneath piceous, shining, the border and last segment pale; ineso-meta-

sternum ])iceous, sliiuing, punctate; legs yellowish testaceous, the coxse and tarsi
piceous. Length 10.5 mm. ; .42 inch.
The explamite border of tlie thorax is broader than in fiisciceps,
but less explanate than \n plnmosa, frontalis, or laticollis. It should
be associated with fasciceps mu] Sallei from the antennte being shorter
than half the body. It is the only species in our fauna with a pice-
ous thorax.
One specimen, collected in Ramsey County, Minn., and given me
by ]\Ir. Otto Lugger.
I*, pltiiuosa Oliv.
The type of this species, which is now in the British Museum, was
collected by M. Francillon in Georgia. An examination of it in
comjiarison with frontalis shows, among other characters, much
smaller eyes, i.e., the eyes when seen from above are scarcely wider
than half the distance to the median line of the head, while in fron-
talis the eyes are fully as wide as the distance to the middle.
ERG.ITKS Serv.
E. neomexicanus Casey is an absolute synonym of E. spiculatus
Lee. The characters given to separate the two are purely individual,
and are seen in specimens from Vancouver as w'ell as in those from
New Mexico.
ACOWA Casey.
The reference of this genus to the Melolonthine series is a mistake.
It is plainly a Laparostict, and, like Pleocoma, has the mouth-parts
of the male (the only sex known) much reduced, and in a manner
similar to Pleocoma. Its position in our series is after the latter
genus.
Polyphylla speciosa Casey, described from the female, is the female
of clecemlineata Say.

^[ale. — Elytra prolonged in a narrow eauda, which is channeled beneath and
curved slightly downward at tip; aiiterior femora with a small tooth near the
knee, the tibia narrowed at base; middle and posterior femora simple; posterior
tibise slightly arcuate, narrow at basal half, rather abruptly dilated in apical
half, in which part the surface is quite asperate.
This species belongs in the series near E. lucoe Lee., but the males
may be easily known by the sexual characters in the front and hind
tibite of Wickhami, which do not exist in the other. The anterior
angles are quite acute forward or even faintly everted in luc(e, and
in the male the elytra are vaguely sulcate, with coai’se obsolete punc-
tures. The legs are relatively longer than in any other Eleodes
known to me.
Collected by Mr. H. F, Wickham near Tucson, Ariz., and named
as an evidence of my appreciation of his labors in that region.
E. longipilosa n. sp. — Piceous-black, moderately shining, surface sparsely
clothed with long, black, flying hairs; head coarsely not closely punctate,
smoother at middle; thorax about a fourth wider than long, sides arcuate in
front, obliquely narrowed posteriorly, disc moderately convex, coarsely sparsely
irregularly punctate, apex slightly emargiuate, anterior angles subacute, but not
everted; elytra elongate oval, more attenuate posteriorly, disc feebly convex,
very vaguely sulcate, surface irregularly sparsely muricate, the two grooves
nearest the suture coarsely punctate ; propleurse wrinkled and sparsely muricate ;
abdomen with first three segments very coarsely punctate and rugose, the last
two segments much smoother. Length 19 mm. ; with cauda, 21.5 mm. ; .76 — .86
inch. PI. 1, fig. 13.
Male. — Elytra prolonged at tip in a cauda, the apices slightly separated, beneath
grooved.
This species is related to candifera, and like it has the femoi-a not
toothed in either sex. The general form is the same as in that spe-
cies, but the elytra are much less evidently striate. It is, however,
especially remarkable in the rather long flying hairs of the surface,
which extend also on the legs even to the humeral joint of the tarsus.

densely punctate, occiput rather deeply impressed ; eyes obliquely oval, prolonged
in an acute angle toward the occiput, limited behind by a smooth depressed
space; thorax quadrate, narrowed near the apex, closely punctate, a median lon-
gitudinal impression, and another less distinct on each side arcuate; elytra
closely punctate scabrous, subopaque; body beneath black, shining, puuctulate;
legs black. Length 7 — 8 mm.; .28 — .32 inch. PI. 1, fig. 10.

111 the males the anterior tibiae have two terminal spurs, the tibiae
flattened on the inner side and densely silken pubescent. In the
female the anterior tibiae are not flattened on the inner side and have
a narrow pubescent line.
This species belongs to a small group containing Rileyi and cavi-
ceps, both of which have peculiarly formed eyes limited behind by
a smooth dejiressed space. This is the only species known to me
with the eyes oblique and acute above.
Collected by Mr. W. G. Wright at San Bernardino, Cal.
E. 9Ierkeliaiia n. sp. — Form slender, piceous, subopaque, not densely
clothed with short cinereous pubescence, entire head, antenme and legs pale
rufo-ferruginous. Antenn® filiform ; head punctate, less closely along the mid-
dle and less densely than the thorax, the median line finely impressed, occiput
entire; thorax longer than wide, sides feebly arcuate, slightly narrowed at base,
apical third obliquely narrowed, median line impressed, a little deeper posteriorly,
surface densely punctulate; elytra closely luinctulate, somewhat scabrous; body
beneath more shining than above, the pubescence longer, although less dense on
the abdomen ; legs rather shining, sparsely punctate, scarcely pubescent. Length
8.5 mm. ; .34 inch.
This species belongs to the series with filiform antennjp, and in the
arrangement proposed by me (Proc. Am. Philos. Soc. 1873, p. 95)
should be placed immediately after trichrus (convolvuli), from which
it differs in its narrow thorax and pale antennae and legs. In the
last two particulars it is the only one so formed in the group.
One specimen from Arizona, probably Fort Whipple, given me
by Mr. A. Merkel.
E. lieterodera n. sp. — Oblong, piceous-black, densely clothed with fulvous
pubescence, varying to cinereous, the thorax of male entirely naked. Antennae
black, filiform; head closely punctate, median line finely impressed, occiput
slightly impressed ; thorax broader than long, rather wider in the male, base
arcuate, sides behind the middle slightly convergent in front and then abruptly
narrowed to the apex, disc rather flat, the median line distinctly imjtressed ;
elytra densely punctulate, vaguely bicostate, the pubescence a little denser along
the suture; body beneath hlack, densely punctulate, vestiture similar to the
tipper surface ; legs black, less densely pubescent. Length 7 — 9.5 mm. ; .28 — .38
inch.
Male. — Thorax smooth, glabrous, suhopaque ; anterior tibiae with two slender
terminal spurs.
FletrirtZe. —Thorax densely puhescent, the pubescence much shorter than on the
elytra, along the basal margin on each side are four puuctiform glabrous fovete,
which are, however, very indistinct in the smaller specimens.
In facies this species resembles ferruginea and sericans, although
with a broader tliorax than either. It is the only species in the
group with filiform antenme in which the thorax is decidedly broader

than long. The most striking character it possesses is in the great
(lissiinihirity of the vestiture of the thorax in the two sexes.
Occurs in northern Florida. Specimens were given me by Dr.
Hamilton and Mr. Henshaw.
TK<j|{OI>EKA Lee.
T. erosa Lee.
The usual form of this species as found at San Diego and vicinity,
has the reticulations of the elytra very coarse. The color is })ale
orange-yellow, always with the tip {)iceous for a short distance. The
specimens seem about equally divided between those with a piceous
band across the middle and those without it.
There occurs in Owen’s Valley, where I collected it rather abun-
dantlv, a form which seems almost entitled to rank as a distinct
species, although I consider it merely a race.
T. erosa, race hitecincta.
Elytra with reticulations much closer than in the typical form,
piceous space at apex better indicated, at middle a rather wide, ex-
actly transverse i)iceous fascia, the edges undulating.
This form seems a little more robust, and the texture of the elytra
firmer and less coriaceous.

the front; thorax narrow, sides parallel near base, narrowed at apical third, a
vague depression at middle of base, surface shining, sparsely punctate; elytra
vaguely bicostate, the surface nearly smooth, the punctures minute and very
indistinct; body beneath black, shining, very sparsely punctate; legs black.
Length 15 — 22 mm.; .60 — .80 inch. PI. 1, fig. 9.
IMe.— Third joint of antennfe broader at base than apex, forming a rounded

area; last ventral segment feebly emarginate.
Eema?e.— Third joint of antenn?e narrower at base tban at apex ; last joint of
maxillary palpus flattened cylindrical, slightly curved ; last ventral segment
with a small but acute incisure.
This species is related to dnbiiabilis (yittigera || Lee.), but differs
notably in the smoother and more shining stirftice, the costte of the

BUPRESTID.E.
Pcecilonota debilis Lee. An examination of the type of this insect
shows it to be merely a female, rather poorly developed of F. cyanipes.
In the female of the latter when of full development there is a feeble
emargination of the last ventral segment. In the debilis the segment
is nearly entire.
DYSTAXIA Lee.
The males of D. Murrayi Lee., the only species known, have the
last ventral deeply and acutely triangularly emarginate. The an-
teniue are slender and extend to a point opposite the first ventral
suture, the female has the last ventral segment broadly rounded
and entire, the antenme shorter, not i-eaching beyond the end of the
metasternum.
In mature specimens the body above is of an entirely uniform
malachite green, with but feeble trace of pubescence.
Before attaining maturity the specimens are dark bronze, with a
coppery tinge, and the gray pubescence is more consi)icuous. On a
specimen of this kind is founded D. Lecontei Thoms.
SCHIZOPITS Lee.
In the typical species of this genus, S. Icefus Lee., the sexes differ
in a more striking manner. In the male the under side of the body,
head and thorax, all the femora and the first two joints of the an-
tennie are bluish submetallic. The elytra are orange-red, with a
narrow sutural edge blue. Probably when quite recent the elytra
are brighter red. The tibise, tarsi and anteniUB, are I'ufo-testaceous.

GEO. H. HORN, M. D.
The last ventral segment is broadly triangularly eniarginate. The
antennje do not extend much beyond the hind angles of the thorax,
and are similar in the sexes.
The female is entirely of a uniform blue above and beneath, some-
times quite green, the last ventral entire.
For the opportunity of recording the sexual differences I am in-
debted to the National Museum at Washington, where numerous
specimens were received from San Diego, Cal.
tS. Sallei Horn was described from a female with scarcely any
trace of metallic siuTace color. The elytra are similar in color to
Mas % , except that there is a darker oblique vitta extending from
the humeral umbone nearly to the sutural angle. The head and
thorax are darker in color.
The oblique impression of the thorax, on which I laid some stress,
seems not to have great value, as it seems to be a variable quantity
in ketm. The claws of Sallei are, however, much less distinctly
cleft, and seem rather to be provided with a small tooth at middle
after the style of some Lachnostern^e.
This species was collected at Mariposa, Cal., by Mr. Alphonse
Thevenet.
Mr. F. Blanchard is quite correct in recording the presence of the
“ ante-coxal piece” of the metasternum in both Schizopus and Dys-
taxia. The presence of this piece seems to be quite characteristic of
the Buprestidse. In the genus Lissomus, of the Throscidse, there is
no trace of this piece, so that by the fortunate discovery by Mr.
Blanchard we have a more ready method of separating the latter
family from the Buprestidte than previously existed, Lissomus having
always been an annoying element.
While the presence of the “ ante-coxal piece” and its modification,
or entire absence, plays an important part in the Adephagous series,
it would hardly have been suspected to have similar utility in a series
so remotely separated as the Serricornia.
ACTENODES Lac.
A. ineiKlax n. sp. — Form of calcarata, but somewhat more convex, color
dark greenish bronze varying to cupreous, feebly shining; antennae short, ob-
tusely serrate ; front rather flat, coarsely and closely punctate, not longitudinally
impressed, surface rather uneven in the female; thorax more than twice as wide
as long, sides parallel, with a slight siuuation, obliquely narrowed at anterior
third, disc regularly convex, moderately coarsely and closely punctate, with a

tendency to form transverse strigae ; elytra with rarely a trace of a costa near
the suture, the surface scabrous, with a tendency to form transverse strigae to a
slight extent, the oblique portion of the margin serrate; body beneath more
shining than above, punctate and transversely strigose. prosternum more coarsely
punctate; anterior femora toothed at outer third. Length 12 — 17 mm. ; .48 — .68
inch.
In both sexes the last ventral is truncate, squarely in the 9 >
slightly eniarginate S . The anterior tibite are serrate in the male
very distinctly, but in the female this is but faintly indicated.
This insect has been a long time in my cabinet, but I refrained
from naming it, hoj)ing that it was a known Mexican form, or that
it would be described in the “ Biologia.” This not proving the case,
and as specimens are occasionally being sent me I have thought it
well that it should be described.
Known to me from Texas to Fort Yuma. A specimen before me
is labeled Illinois, but the locality is open to doubt.
Bibliographical Reviews.
In a recently published part of the “ Biologia Centrali-Americana
(vol. iii, pt. 1),” in reviewing the Throscidje, it was observed that
Throscus, as then constituted, was clearly divisible into two genera ;
Throscus includes those in which the metasternum is simply ob-
liquely impressed, while
Aulonothroscus will receive those with a rather deep and well-
defined groove. To this division belong validus, punctatus, invisus,
condridor, convergens and pugnax, the remaining species will continue
as Throscus, all the European species belonging here, and must be
accepted as the typical forms.
In the same essay, a few pages after, it will be observed that the
name Tharops has been superceded by Isorhipis, the former name
having been previously used.
As an illustration of the rather restricted distribution of the Euc-
nemidae generally, it will be observed that but few species occur
south of our boundary which are found within it, these are Nematodes
atropos, Mirn'orhagus humeralis and Anelastes Druryi, the first being
somewhat doubtful, while the last is represented in both its races the
shining {Latreillei) and opaque (Druryi) as far south as Guatemala.

(ii:0. H. HORN, M. D.
In the Mexican fauna the species of the family Throscidje show
nothing in common. In onr fauna Throscus sens. lat. is represented
hy thirteen species, and in ^Mexico by five, while Drapetes contains
twenty-six in ^Mexico and hut four with us, in addition to which
Lissomus has twelve Mexican species, and is totally unknown in our
fauna. Pactopus makes a closer approach to the Eucnemidse without
having any parallel in Mexico.

There has recently a])peared from the able hands of Dr. Candeze
a work entitled, “ Catalogue Methodique des tllaterides connus en
1890,” which will have great value to those interested in the study
of that family. In it all impertinent synonymy has been omitted,
only such being given as has not already obtained sufficiently wide
circulation. But little has been observed worthy of correction in
reference to our species, except that Megapenthes granulosus Mels, is
on ]). 98, while its male is found on p. 190 as Ludius limbalis Hbst.
Our Betarmon higeminatus Rand, has been omitted. The results of
my studies of Cryptohypnus are included in the list, although I have
slightly modified the arrangement of the species since my communi-
cation to him.

Desoriptioii!4 of new species of North Annericaii Bees.
BY CHARLES ROBERTSON.
ANDRENA.
In the study of the mutual relations of flowers and insects I have
found many insects which I could neither determine myself nor get
determined by others. Conspicuous among these are the species of
Andrena. In order, therefore, to get names for use in my biological
work, I have undertaken to describe as best I could the species which
occur in my neighborhood. Some of them may have been described
before, by Smith, in British Museum Cat. Hym. and in New Spec.
Hym. Brit. Mus. After careful study I have been unable to deter-
mine more than two of Smith’s species. The fact that a specimen
agrees in every detail with Smith’s description would not, to my
mind, establish the probability of its being the same as its type. His
descriptions are limited almost entirely to the colors of the pubes-
cence, which is variable and liable to fade. Thus, of the twenty-four
female specimens of A. Cressonii, only three show the normal color
of the pubescence. The color of the surface is also very variable.
The abdomen sometimes varies from entirely red to entirelv black.
Sets of specimens in which the legs are commonly black, with the
apical joints ferruginous, often show individuals having the tarsi, the
middle tibiae at tips, and the hind tibiae entirely ferruginous.
In all, or most of the species, the ground surface is minutely rough-
ened. Unless there is a distinct punctuation in addition to this, I
call the surface impunctate. One trouble with Smith’s descriptions
is that one cannot always be certain whether he refers to this minutely
roughened surface or to a distinct punctuation.
Of the twenty-six species of Andrena mentioned in this paper, I
have both sexes, except in five cases. I have taken the sexes of
eleven species in copula. These bees can best be collected by watch-
ing flowers of willows in Spring and of Composite in fall. The
females should be identified first and the males referred to them.
I submit a synopsis of all the species which occur in my neighbor-
hood (Carlinville, 111.) with notes on their time of flight and the
flowers which they visit, as well as descriptions of the new species.
Besides those given below I have ten sets of specimens which indi-
cate the presence of several additional species.

CATAI.OGIIE OF THE HE^CRIBED SPEC’IES OF
SOUTH AMERICAN ASIEID.E.
BY S. W. WILLISTON.
'File following preliminary catalogue of the described species of
South American Asilidse is offered in the hope that it may lighten
the labors of students of the South American Dipterous fauna. It
was originally prejiared, two years ago, as a preliminary to the study
of a Brazilian collection in this family, and has been recently sub-
jected to a careful revision. It will be strange if, among so many
references, some errors, both of omission and commission, are not
found. I can only say in extenuation of such, that the entire paper
has been repeatedly written and the references as often compared.
Schiller’s list of specific names of the Asilidie of the world, which
seems to be very complete to 1860, has been of material service, as
also Lynch’s partial catalogue. The distribution of the genera is
chiefly that of Schiner ; some few changes have been made in ac-
cordance with Lynch’s, Osteu Sackeu’s, or my own views. A very
few of the less important works have been inaccessible to me, and it
is in them that additional references may be found. The references
thus taken at second hand will be found preceded by an asterisk.
No references later than 1889 are included.

W. H. ASHMEAI).
A GKIVERIC' SYl^OPSIS OF THE €OC'< IIEE.
BY WILLIAM H. ASHMEAD.
Family X. — COCCIDtE.
Soft liodied insects of the smallest size. The females and the
young larvse, of both sexes, are degraded, mite-like in appearance,
oval or elli))tical in shape, with the head not distinctly sej)arable
from the thoracic segment, apjiearing merely as a segment with
rounded eyes placed toward the sides, the short, subsetaceous, 5- to
11-jointed antenme being situated just a little in advance. Ocelli
usually present. Beak usually 1 -jointed, and seldom with more than
2 joints, enclosing 4 long, delicate setae. Legs usually short ; tarsi
1 -jointed and usually with digitules. The adult males, in this anom-
alous family, present a very different appearance from the females
and young larvie ; they are elongate ovate, with a well developed
thorax, a large scutellum, a distinct, small, rounded or quadrately
shaped head, with the eyes quite large, either smooth or facetted,
while the antenme are long, filiform, and composed of from 9 to 11
joints, usually ])ubescent, but occasionally with whorls of hairs.
The beak, in this sex, is wanting ; where it should be, are two large,
shining ocelli. The legs are of moderate length, never greatly thick-
ened ; the tibiae sometimes as thick, or thicker than the femora;
tarsi 1 -jointed, stout, ending in a single claw, and usually furnished
with knobbed digitules. Most of the males known in this family
have two wings, the venation consisting of a single longitudinal vein
with a simple, oblique, discoidal branch, the hind wings being aborted,
and in their place is a pair of halters, as in the Diptera. Some few
males in the genus Lecaniwn have been discovered recently to be
entirely wingless, and it is quite probable that with closer study wing-
less males in other genera will be found. Subapterous males are
not uncommon. The abdomen in the male is simple, or terminates
in two long caudal setse, a brush of filamentous down, or then armed
with a long stylus, with oi‘ without caudal setse.
The habits of this anomalous family are quite interesting; the
vast majority of the species becoming quiescent and stationary upon
their food-plants, cover themselves with a waxy or calcareous sub-
stance, which, together with their castings or moults, affords a jiro-
tection for their soft bodies, termed a scale, shield, test, sac or en-
venope. The name, therefore, popularly given to them — “Scale
insect” — is very appropriate, although some of them do not become
GENERA OF COCCID^.
93
quiescent and form the scaly covering, but are capable of moving
freely about on their food-j)lant, entirely unprotected, oi- then only
covered with a filamentous, floccnlent or pulverulent substance,
whilst a few species have been discovered in Australia living in galls
or excrescences, on the leaves of the Eucalyptus tree. I also know
of a gall-rnaking species in Florida.
ihe family may be divided conveniently into five subfamilies,
apparently natural groups, based upon the studies of Signoret, Tar-
gione, Low, Masked, Comstock, Atkinson and others, recognizable
by the aid of the following table ;
Table of Subfamilies.
Species not livinji in tubes or galls, naked, or covered with a waxy, calcareous,
or cottony secretion.

Adult 9 with 8-9-jointed auteunte; with 10-jointed antennae; ocelli
present; eyes usually smooth ; abdomen always with two long caudal
filaments Subfamily II.— COGGING.
Lower lip 1-jointed ; anal extremity distinctly cleft, or tubercular.
Anal extremity cleft with two triangular lobes or plates above; adult
with 9-10-jointed antennae; abdomen terminating in a long caudal
stylus and two long caudal filaments Subfamily III. — LEGANIIN^,
Anal extremity not, or but slightly cleft, strongly tuberculous, no plates
above; with 10-jointed antennte ; abdomen terminating in a caudal
stylus, but the caudal filaments absent Subfamily IV. — DIASPIN.®.
Species living iu tubes or galls, apodous, or with atrophied legs.

KOTES OX SOME X0CTEI03E, WITH DESCRIPTIOXS
OF XEW^ OEXERA AXD SPECIES.
BY JOHN B. SMITH.
Cernia olivacea n. sp. — Ground color an olivaceous gray, with bluish
green and white powderings. Head and thorax irregularly mottled, with a con-
siderable admixture of black scales. Basal line distinct, black, followed by a
white line. T. a. line black, preceded by a white line with long outward teeth
on the subcostal and median veins, an incurve in submedian interspace, with
another long tooth on the internal vein. T. p. line is irregular, rivulous, in gen-
eral course a rather even outcurve. S. t. line indefinite, the space between t. p.
line and outer margin being irregularly blotchy; an even dusky terminal line.
Fringes pale, cut with fuscous. Claviform concolorous, defined by a black semi-
circle below the orbicular and a vague black pow’dering from the horns of this
to the t. a. line. Orbicular moderate in size, round, concolorous, defined by a
greenish annulus edged with black scales, and with a whitish central dot. Reni-
form large, somewhat constricted medially very incompletely defined in black,
with greenish powderings which extend to the costal margin. Secondaries
smoky fuscous, somewhat paler basally, with a small discal lunule and a faint
extra median line. Beneath, primaries blackish powdery, paler along inner
margin ; secondaries whitish, with a dark discal lunule and a powdery outer
margin. Expands 1.20 — 1.28 inches; 30 — 32 mm.
Hab. — Colorado ; Sierra Nevada, Cal.
I have seen three specimens of this very distinct species, all males.
Two are from Mr. Edwards, one of them rather rubbed, the third is
from ]\Ir. Bruce’s collecting, sent several years ago to Mr. Cramer,
now in collection United States National Museum. In this specimen
the green has faded to the sordid yellow so commonly assumed by
this color in the noctuids, but in maculation there is absolutely no
difference. It is much larger than the eastern C- cora, and the de-
tails of maculation differ quite widely while the pattern remains
similar. It is fully congeneric with our eastern species, without
meaning to assert its distinctness from Bryophila.
’ I
Pacliiiobia ciiieraseens ii. sp. — Pale luteous gray ; sometimes with a
slight reddish suffusion, sometimes quite well powdered with black scales. Head
and thorax concolorous. Basal line distinct, rigid, single. T. a. line single,
blackish, oblique, outwardly angulated below the costa, nearly straight through
the cell, outcurved in the submedian and marginal interspace. T. p. line single,
blackish, distinct, only a little outcurved over the cell, finely crenulated. S. t.
line concolorous, marked by a defined blackish preceding shade, which fades into
the ground color before the t. p. line. A broken brown terminal line, followed
by a faint yellowish line at base of fringes. Claviform wanting; orbicular round

or oval, hlackisb. without defining line. Ecniforin large, upright, ohlong, hlackish,
without distinct defining line. Secondaries smoky gray, uniform, with a fairly
distinct yellowish line at base of fringes. Beneatli gray, primaries vaiying to
smoky brown, secondaries ))owdery. A common, varialily complete outer line
and a distinct large discal spot sometimes obscured on the primaries. E.xpands
1.20 — 1.40 inch. ; 30 — 3.5 mm.
Hub. — Alameda County, Cal., September and October.
Four male specimens are in the museum collection (through C. V.
Uiley) hearing the red number 339.
This species is aberrant in color for the genus, hut in wing form
and in pattern of ornamentation it is allied to carnea. Its luteous
gray color, single median lines, and contrasting black ordinary spots,
render it easily recognizable. The antennae are “ brush like,’’ l.e.,
the joints slightly produced laterally and furnished with bristly
tufts. The thoracic vestiture forms an indefinite dorsal crest. The
male genitalia have the harpes ohliijue at tip, forming a little pro-
jecting tooth interiorly. The clasper is a single, stout, straight,
pointed, corneous spur.
" A / ^
l*acliiiobisi elevata u. sp. — Ground color of the reddish gray usual in
this genus. Head and thorax immaculate. Primaries with the ordinary lines
single. Basal line interrupted, rather indefinite. T. a. line incomplete, ap-
jiarently upright and rather even to internal vein, below which it makes an
outcurve. T. p. line complete, even, exserted over the cell, and somewhat ir-
regularly ohliipie below to margin. A paler, more grayish shade through the
s. t. space, in which a series of interspaceal brown dashes indicate the s. t. line.
.\u interrupted terminal line. Claviform a yellowish streak from base to near
middle of median space, outlined beyond t. a. line by a narrow black line. Or-
bicular elongate, the angles drawn out toward base and apex. Eeiiiform small,
lunate. Both spots are a somewhat paler gray and outlined by black scales.
Secondaries whitish, smoky toward apices. Beneath whitish, powdery, with a
diffuse common outer line and a moderate discal spot on all wings. Expands
1.40 inches; .35 mm.
Hab. — Colorado (Bruce).
A single good male from Mr. Neumoegen’s collection. The speci-
men has the antenine serrate and bristled, and is therefore allied to
C'lrnea, than which it has .somewhat more pointed wings and entirely
diflerent markings. The cell is not black-filled around the ordinary
spots, and the character of the transverse lines is entirely different.
The genitalia consist of a broad harpe with obtusely rounded tip,
inwardly fringed with spinules. From the centre of this arises a
broad, excavated, corneous process, with an irregular outline, form-
ing the clasper.

Ciii'iiesMleM f'lii^iiiiaciila n. sp. — Head and thorax mouse-gray, collar with
a blackish central line. Primaries dull red-brown, subcostal and median vein
white i)owdered. Basal line geminate, well defined, included space with white
powderings. T. a. line geminate, interrupted below costa, a long inward angle
on cell, then evenly oblique outwardly to hind margin. Below the median vein
the defining lines are well written, the included space concolorous. T. p. line
even, outcurved over cell, thence parallel with outer margin. The inner de-
fining line is a series of blackish lunules, the outer a vague, diffn.se line, the in-
cluded space very slightly paler than ground color. S. t. line marked only by
the slight difference in shade between s. t. and terminal spaces; an interrupted,
sublimate terminal black line, followed by a narrow yellow line at base of fringes.
Apical spot powdered by a few white scales; a black basal dash below median
vein, joining to the moderate, black margined claviform. A black filling to the
cell before orbicular, and between the ordinary spots. The latter are fused, the
orbicular oblong, oblique, merging interiorly into the reniform, which is some-
what extended outwardly from its lower angle. The combined spot narrowly
black ringed with a white interior line and a few white scales relieving the other-

fringes. Beneath smoky fuscous, powdery, with an incomplete outer line and
somewhat indefinite discal lunule. Expands 1.28 inches; 32 mm.
Hab. — California.
A single male specimen iti good condition. The characters of the
tessellata group are well marked, and the sjtecies is intertuediate
between divergens and redhnicula, differing amply from both in the
fused ordinary spots. The white marked veins are like divergens,
while the s. t. line is like redimieula. The male characters agree
with those of the allied species, and figure 64 of my Revision of
Agrotis will answer for this species equally well.
I*erig<*a piilveriileiita n. sp.— fTi-ound color a vague, powdery reddish
gray, varying in tint according to the relative ju-edominence of red, white, or
blackish scales. All the noiinal maculation present, hut obscured by the pow-
dery ba.se. Basal line geminate, concolorous, defining lines fuscous or blackish,
twice augulated. T. a. line somewhat paler, with fuscous or black defining
lines, not always complete and sometimes vague; outwardly oblique, somewhat
curved, inwardly angulate on the median and submedian veins. T. p. line ob-
soletely geminate, the inner line lunulate, the outer vague and even, sometimes
wanting, its course evenly bisinuate without the usual long outcurve from the
costa over reniform. S. t. space palei- than median and usually also than terminal
space; s. t. line pale, diffuse, sinuate, marked by the difierence in shade between
s. t. and terminal space, and also djy a more or less obvious preceding shade,
h'ringes interlined with fuscou.s, feebly scalloped: median space, as a whole,
somewhat darker than the rest of the wing; a dusky or blackish median shade
which in the submedian interspace sometimes forms a complete connection be-
tween the median lines. Claviform small, though quite wide, concolorous, in-
completely outlined in black. Orbicular round or oval, oblique, pale ringed with
dusky centre. Reniform uiiright, quite large, somewhat constricted centrally,

broad black outer margin, a narrow preceding dusky line and a dusky discal
lunule. Fringes pale, interlined with fuscous. Beneath powdery, primaries
darker, both wings with a discal spot, narrow outer line and broad dark outer
margin, all variable in distinctness. Expands 1.00--1.08 inches; 25 — 27 mm.
Hub. — Colorado (Bruce); Las Vegas, N. Mex. (Meeske); New
Mexico (Show); Arizona (Edwards).
This little species has long puzzled me, and I refer it to Perirjea,
rather because it is congeneric with P. pei'plexa Grt., than because
it strictly belongs here.
Four of the specimens collected by Mr. Bruce are in the collection
of the United States National IMuseum, two of them labeled simply
“ Colorado,” the others labeled “ Foot-hills.” There is little or no
variation, and the species once generically [ilaced, is easily recogniz-
able.
l*oliit pul VPrnloiita n. sp — Ground color a powdery ashen gray, the
markings indefinite, vague. Basal Hue black, interrupted, apparently single.
T. a. line single, black, rather diffuse, outwardly oblique and somewhat outcurved
between the veins. T. p. line crenulate. outcurved over the cell and parallel
with outer margin below that point, blackish, interrupted, almost lunulated, and
nearly obsolete toward costa. This line is quite well removed toward margin,
widening the median space and narrowing the space beyond to the outer margin.
A series of somewhat diffuse iuterspaceal black marks indicates the s. t. line: a
series of small terminal lunules. Fringes gray. Claviform vaguely indicated
by a blackish shade. Ordinary spots vague, indefinite, concolorous, incompletely
outlined, apparently of the usual shape and proportionate in size. An oblique,
diffuse blackish shade from costa, outwardly over the reniform and darkening
it interiorly; continued as a vague fuscous shading through the median space.
Secondaries dirty white, powdery, veins soiled, a dusky lunate marginal line and
discal spot and extra discal line of under side showing through. Beneath
whitish, powdery, with a common extra discal line and a discal spot on all wings.
The hind angle of primaries is somewhat retracted ; thorax with a small, divided
anterior crest, and a more distinct posterior tuft ; abdominal tufts small. Ex-
pands 1.88 — 2.08 inches; 47 — 52 mm.
Hab. — Colorado.
Two male specimens with serrate and tufted (brush-like) tintenna.
This species, though referred to Polia, jirobably cannot remain in
this genus. It is referred there because it is quite close to and per-
fectly congeneric with Polia contacta Wlk., which it resembles both
in size, color and general habitus, differing abundantly in many re-
spects. The species liears a very decided resemblance to Mamestra
discalis, and a specimen in the Museum collection (from the Meske
collection) bears Mr. Grote’s label, Mamestra discalis. The specimen

was collected by Snow, and I feel assured there are others of this
species so misnamed. The other specimen was sent me by Mr.
Bruce.
The genus Folia contains quite diverse material, and the species
will probably be distributed among other genera, some mayhap to
Hadena. Indeed, Mr. Grote has described the same species as a
Hadenu (diversilineata), and again as a Folia (illepida).
€AL,OPHASIA Steph.
Head not retracted. Thorax with fine, smooth vestiture. Abdo-
men without dorsal tufts. Antenme of male with short, rather dense
cilire, at base with a feeble tuft, thorax posteriorly with a truncate
tuft. Primaries short, widening outwardly, more strongly rounded
at internal angle, outer margin and fringes entire. The above char-
acterization is from von Heinemann (Schmett. Deutsch. 391), and
with it agrees fairly well a species which does not seem to fall in
naturally with any American genus known to me. In wing form
the species agrees well with opalina ; in type of maculation it is more
like platyptera, the latter being wider Avinged than its congener.
PalopliHSia strigata n. sp. — Head, thorax and primaries ash-gray. Head
marked with fuscous, collar paler at base. Thorax with an admixture of fus-
cous scales. Primaries with a dusky shade through the cell and terminally, the
transverse lines obsolete; the veins are ail black marked, and the wing has
therefore, a strigate appearance. Claviform long, extending from the base to
beyond the middle of the wing, with narrow black defining lines, filled with a
reddish sulfusion. A faint reddish tinge beyond the reniform, which is white
ringed, narrow, upright, with an inferior spur projecting inwardly toward the
orbicular. The latter is narrow, clavate, oblique, white ringed. On veins 3 and
4 the dusky terminal shade is cut by a white shade accompan.ying the veins- a
row of small, dusky terminal lunules. Fringes cut with fuscous, and rather lout^

Two female specimens are before me, neither of them entirely
perfect, but yet in excellent condition. The species has the appear-
ance of Oncocnemis without its structure. One of the sjiecimens is
in the United States National Museum.

ter mostly flattened scales, collar not crested. The palpi with coarse
vestiture and small terminal joint. Antenme at base with a tiift of
hair, serrated in the males, with bristle tuftings. The thorax quad-
rate, laterally produced at the angles, with smooth anterior and pos-
terior tufts, abdomen untufted. Primaries short, not greatly widen-
ing, apices not acute, margin evenly rounded, fringes scalloped.
This is von Heinemann’s definition, and it agrees well with the
European species, but not at all with the American species referred
to the genus. Dryobata opina Mr. Grote now refers to Valeri)i, while
stiymaia is utterly unlike the European species. The wing form is
alisolutely different, the fringes are only feebly sinuate and not scal-
loped, and the abdomen is prominently tufted ; but I know at
jiresent no other genus to which stigmata could be better referred, and
as I believe it has congeners in other genera I will simply call atten-
tion to the fact, here, preliminary to the description of three species
agreeing better with the description of the genus, but very unlike
stigmata in every respect, and, though themselves congeneric, and
with the same habitus, differing quite strongly in antennal structure.
The species are ash-gray, with a reddish or brownish suffusion,
])owdery, all the maculation well marked. The ordinary spots are
well sized, and as a whole the species have a very decided resem-
blance to Litholomia napee in type of maculation, emphasized by the
more or less prominent, rigid, dark, median shade or line, which
forms the most obvious ornamental feature. One of the species
which I had dubbed Hadena latifascia, perhaps in one or two collec-
tions, I find is Prof. French’s Homohadena elda. It has nothing,
whatever, in common with Homohadena, and this species is perhaps
nearest of all to tyjiical form of the genus.
I>i\yobata elda French.

The male autennge are di.stiuctly and well pectinated; in the female the joints
are marked. A broad brown shade with blackish defining lines fills the space
between the ordinary spots, and below the median vein its outer border extends
along the t. p. line.
Four specimens in the National Museum collection (through C.
V. Riley) are from Nevada County, Cal., Septemher, collected by
Koebele, and Mr. Edwards has also sent it to me labeled Sierra
Nevada, Cal.
I>ryobata rectiTai^icia u. sp. — Eather dark bluish ashen. Collar with a
broad median black line. Basal half line distinct, pale, obsoletely geminate; a
short, black, longitudinal basal line extending to the half line, the inclosed costal

space paler and with a brick-red tinge. T. a. line upright, or a little outwardly
oblique, geminate, outer defining line usually very distinct and touching the
orbicular in its course. T. p. line geminate, inner line darker, included space
paler; in course it is very even, widely outcurved over the reniform, altogether
what might be termed S-shaped, with most of lower extension lopped ofl’. The
s. t. si)ace is pale, except costally, darkening to form a continuous dusky shade
before tbe s. t. line, which is pale and irregularly sinuate. Tliere is an admix-
ture of reddish scales in this preceding shade which is most obvious at anal
angle. A prominent, rigid black line from the costa, forming the inner margin
of reniform and continued thence to the hind margin at t. p. line. Claviform
small, indefinite, marked only by a vague brick-red shade. Reniform large,
kidney-shaped, suffused with brick-red : a black line at base of fringes, which
have a dusky interline. Secondaries soiled white, veins and terminal line dusky.
Beneath whitish powdery, with a more or less complete outei' line and discal
spot. Expands 1.24 — 1.40 inches; 31 — 3.5 mm.
Hab. — Sierra Nevada, Cal. (Edwards).
The anteimte of the male have the joints but feebly marked and
ciliated, not at all serrate, much less pectinated. The transverse
median line corresponds to the outer defining line of the median
shade in elda, but is more prominent. The differences in details need
not be pointed out where structural characters declare the species
difierent.
An incomplete specimen is in the United States National Museum ;
the wings and antennm are, however, perfect, and the specimen is
one of my types.
Dryobota. ciirvitascia n. sp. — Asheu-gray or darker, with or without
an admixture of hiick-red scales, the black maculatiou consisting generally of
elevated scales, giving the species a rough or “squammose” appearance. Collar
inferiorly pale, a vague reddish median line, surmounted by an equally vague
blackish one. Primaries, basal line geminate, blackish, vague, reaching to the
short black basal dash, along which a brick-red shade is more or less marked.
T. a. Hue geminate, incomplete, outwardly oblique and slightly curved between
the veins. T. p. line vague, scarcely definable, obsoletely geminate, evenly out-
curved over cell, and incurved beneath. The s. t. space is outwardly a little
paler, a partial series of black or blackish lunules, becoming more distinct toward
inner margin ; an admixture of reddish in these lunules also increases toward
anal angle. Terminal space dusky; a blackish terminal line and a narrow pale
line at base of fringes. Claviform apparently obsolete. Orbicular oblong, ob-
lique, concolorous, with a narrow black margin and a very narrow white annulus.
Reniform narrow, quite long, lunate, shot with reddish, defined by black and
white scales rather than lines. A dusky median shade, feebly Insinuate, touch-
ing neither of the spots and reaching margin between the ordinary lines. Sec-
ondaries soiled white or smoky, with a blackish terminal line. Beneath pow-
dery, pale, with a variably distinct discal spot and outer line. Expands 1.12 —
1.20 inches ; 28—30 mm.
Hab. — Sierra Nevada, Cal. (Edwards), September ; Placer County,
C'al., through C. V. Riley.

JOHN B. SMITH.
The Placer County specimen in the United States National Mu-
seum is the smallest of the three, and is also most obscurely marked.
It lacks the brick-red shades altogether, the gray is more sordid and
even, and the maculation is less definite than in the other specimens.
The male antemue are rather lengthily serrated, almost pectinated,
differing from both the j)receding species in this character as well as
in the median shade, which is here not at all prominent, narrow and
sinuate, not touching either of the ordinary s[)Ots nor the t. p. line.
Apainea liiiiata u. sp. — Ground color a powdery reddish ocher. Head
and thorax innuaculate. Primaries with basal line apparently wanting. T. a.
line narrow, vvhitish, evenly outcurved. T. p. narrow, whitish, even, but little
outcurved over cell and rigidly oblique below. S. t. line marked by a j)receding
costal shade and a series of interspaceal black dots; a brown line at base of
fringes. Claviform and orbicular obsolete. Reniform a narrow white lunule,
margined by black scales at the end of the cell. The veins, through the median
space, are more or less evidently black powdered Secondaries very pale cop-
pery, somewhat more dusky outwardly. Beneath pale, with reddish powderings.
Expands l.Ol — 1.12 inches; 26 — 28 mm.
Hab. — Alameda, Cal., iu June; Mt. Shasta District, Cal. (Ed-
wards).
15oth sexes are before me. The species is allied to parpnripennis
Grt., but the ground color is entirely different, and there is not the
least chance of confusing the species. The male antennae are later-
ally tufted with short bristly hair, but not serrate.
Orthosia disUeha Morr. has hairy eyes, and is an Ulolonche Smith.
Tt comes close to U. fasciata in type of maculation as ivell as wing
form ; but besides the difference in color the contrasts are nowhere as
defined, and the reniform is not discolorous, though it is well defined
and of the .same form.
The male genitalia agree perfectly in type with the species which
I have already included in this genus (pnodesta, fascuda, niveignttata) .
This seems to be oue of the cases where the sexual structure is of
generic, rather than specific importance, the agreement being close
in type and in details, while the ornamental characters are widely
variant.
Telesilla carneola n. sp. — Head and thorax a carueous or vinous gray,
powdery, apparently without distinctive ornamentation, but the specimen is
imperfect iu this respect. Primaries with a fine vinous red ground color, more
or less evidently gray powdered, median space with a deep, blackish brown
shading. Terminal space deep umber-brown. Basal line very indistinct, nar-
row. composed of whitish atoms. T. a. line narrow, thread like, [lowdery, gray,
slightly outcurved. T. }i. hue vague, powdery, defined rather by the difference

in shade between the median and subterminal space, and by short black lines on
the veins, followed by minute white dots; a whitish powdering through the s. t.
space, which becomes darker outwardly, shading into the deep brown terminal
space. S. t. line very indistinct, broken, barely traceable, its course irregular.
Fringes dark, with a grayish central line. Orbicular small, round, concolorous
outlined in pale gray. Eeniform slightly constricted medially, concoloroms, out-
lined by a narrow gray line. Secondaries yellow fuscous at base, becoming
smoky outwardly, a pale line at base of fringes. Beneath brown, powdery, with
a median line and vague discal spot on primaries. Secondaries pale basally, a
broad dark extra median line and a small discal dot. Expands 1 inch ; 25 mm.
Hub. — Las Vegas, N. Mex. (H. Meeskej.
A single specimen from Mr. IS'eumoegen’s collection, taken by Mr.
Meeske in 1889.
Compared with the eastern cinereola, the present species is stouter
in body, with narrower wings. The general scheme of maculation
is identical, but the contrasts are much greater. While there is an
evident resemblance there can be no danger of confusion with the
eastern form.
Dr. Harvey’s navia has a tuberculated front and anned fore tibiai,
and belongs, therefore, with the Stiriin^. It may be best referred
to Stibadium for the present.
As Mr. Grote has recently avowed his responsibility for Dr. Har-
vey’s species, the failure to see the obvious structural characters
separating this species generically from cinereola, is chargeable to
the former.
I*liisia augiilidens n. sp.— Head, thorax and primaries bluish gray in
ground color, with fuscous powderings. Collar with a median and subterminal
fuscous line, and the patagise have also two rather diffuse transverse lines. Tho-
racic tuft brown, basal abdominal tuft almost black, but with a white margin.
Primaries with the basal line distinct, black, geminate, inwardly oblique from
the costa. T. a. line inwardly oblique, with three feeble outcurves, outer line
black, inner vague, and marked on the costa principally, though also traceable
below internal vein ; the line is interrupted on the median vein, where, at the
origin of vein 2, the greenish silver u is attached, much as in ou. A very small
silver dot follows, but is completely and even widely separated. The median
space is vaguely and irregularly fuscous shaded. T. p. line oblique, almost par-
allel with the outer margin, irregularly aiid feebly angulate outwardly ; the line
is whitish centered, the geminate defining lines fuscous. S. t. line prominent,
black, irregularly and widely angulated and dentate, shading off by a fuscous
tinge into the s. t. space, hut sharply contrasted against the bluish gray terminal
space. This character forms the most obvious feature in the ornamentation. A
fuscous shading near outer margin, forming irregular patches snbapically.
Fringes gray, cut with fuscous. Orbicular a very vague, oval, oblique spot.
Reniform narrow, upright concolorous, very imperfectly defined by narrow black
lines. Secondaries yellowish fuscous basally, with a broad smoky brown outer

Hab. —Colorado ( Bruce).
The species is allied to P. viridislc/nata Grt., or yet more cliKsely to
celsa Itdw., of the latter of which iNIr. Neumoegen has the type. It
differs from both iu the greater prominence and angulation of the
s. t. line, and from the latter in the less distinct transverse macula-
tion, and the want of the black shadings described by Mr. Edwards.
The underside of the new species does not agree at all with what
that of cebsa, next to which, however, it must probably stand. Sev-
eral specimens were taken by Mr. Bruce, who has also taken F.
snowi in .some numbers.
Cirrhophiiiies diiplicatiis n. sp. — Ground color pale ocher yellow, with
the niaculation deeper, orange yellow. Head and thorax immaculate, the tho-
racic tuftings orange tipped. Primaries with a coppery flush over costal region
to middle of wing, and in discal cell. Ordinary lines single. Basal line l)avely
visible. T. a. line widely angulated on subcostal vein, in submediau interspace,
and again to the hind margin. T. p. line even or very feebly lunate, widely
outcurved over cell, then very obliquely inward to the middle of the hind mar-
gin. S. t. line very di.stinct, broader than the others, even, parallel with outer
margin. A rich orange line at base of fringes. A somewhat deeper shading
through the terminal space. All the veins orange marked. Ordinary spots ob-
solete. Secondaries ocherous, paler at base, and with an orange terminal line.
Beneath, primaries reddish ocberou.s, secondaries pale, powdery. Expands 1.16
inches ; 29 mm.
Hab. — Platte Canon, Col., 6500 feet.
This species, collected by Mr. Bruce, is before me in one female
specimen only. It is somewhat smaller than triangulifer, and lacks
altogether the rich tinting of that species. In niaculation the two
are very much alike. The frontal jtrotuberance of the new sjiecies
consists of a simple nipple-like dilation, differing quite strongly from
trianc/u lifer, and the fore tibite seem unarmed. The specimen is im-
perfect iu leg structure — most of the legs wanting — and the claw
may have been broken off. In thoracic tufting, wing form and gen-
eral habitus, this species is the close ally of its congener.
The specimen is in the United States National Museum.
Ori'liodia Ciilitorniea u. sp.— Head, thorax and primaries a deep, rather
sordid luteous brown, with clo.se, black powderings beyoud the t. p. line, dark-
ening the primaries terminally. Head and thorax immaculate. Basal line
scarcely traceable. T. a. line geminate, defining lines a series of black scales,
included space pale: in course the line is outwardly oblique and outcurved be-
tween the veins. T. p. line geminate, pale, the defining lines blackish, very

even, its general course bisinuate, outcurved over, incurved below tbe cell.
Througb the dusky outer portion of the wing the veins are pale, and the irregu-
lar, indefinite concolorous s. t. line is rather indistinctly traceable. A row of
black terminal lunules. Fringes with a pale line at base. Claviform vaguely
indicated by fuscous brown scales. Orbicular upright oblong, pale ringed and
dusky powdered; reniforin large, slightly constricted centrally, pale ringed and
black powdered. Secondaries even, fuscous brown. Beneath fawn gray, pow-
dery ; secondaries paler basally ; both wings with an outer line and dusky discal
lunule. Expands 1.36 inches ; 34 min.
Hab. — Sierra Nevada, Cal.
A single male from Mr. Edwards’ collection with “ brush-like”
antenme. In habitus and appearance this species resembles a Tcenio-
campa, but the eyes are naked and strongly lashed. It is congeneric
with the European 0. silene, and seems distinct from our species of
Gkea and allies.
In introducing the term Orrhodia into our fauna I do it not to
replace any term now in use, but because it seems as though it really
refers to a tyjie different from the others heretofore noted. The Eu-
ropean species .seem very unlike each other and may not be held
together. On the other hand additional material of the species
before me may indicate another genus. The type is perfect, exce|)t
that one antenna is missing.
l*LEROMA 11. geu.
Eyes naked, with long hairy lashes. Head retracted, moderate in
size, with divergent hairy vestiture, palpi short, scarcely e.xceediug
the frontal vestiture, divergently clothed. Tongue moderate, spiral.
Thorax quadrate, heavy, vestiture long, somewhat flattened hair;
collar somewhat [iroduced in front, forming a central crest ; an in-
definite loose posterior tuft. Breast densely clothed with long woolly
hair. Legs unarmed, short, stout, with dense, long woolly hair on
femora and tibise. Abdomen with dorsal tuftings, short, stout, conic
in the female and scarcely exceeding hind angles of the secondaries
in either sex. Antenme simple in both sexes. Primaries trigonate,
comparatively short and broad, with produced apices and a verv ob-
lique, evenly curved outer margin, joining with the inner margin at
a very obtusely rounded angle. Secondaries proportionate, fringes
long.
I could not satisfactorily refer the species with the above comliina-
tion of characters to any of the described genera. It is evidently
related to Xylhia without the depressed form and narrow wings.

I*, obliqiiata n. sp. — Bluish ash-gray, varying in depth of tint from whitish
to very deep, almost blackish. Collar with a central white line between two
black lines, which in a pale specimen is reduced to a central black line and a
fuscous upper line. Thorax with black hair intermixed, but forming no distinct
ornamentation. Primaries with all the veins black marked. T. a. line single,
quite broad, outcurved, but distinct only into the submedian interspace and not
attaining the inner margin. T. p. line single, fuscous to black, almost parallel
with outer margin, followed by a narrow pale shade. An oblique, broad, dusky
shade, sometimes broken up into spots from the apex to the hind margin near
the t. p. line. S. t. line vague, broken, in pale specimens marked only by pre-
ceding black interspaceal marks. A dusky line at base of fringes, which alter-
nate in two very slightly different shades of gray and have a pale central line.
The ordinary spots are wanting, only the reniform being vagviely indicated by
a dusky shade, more evident in pale specimens. Secondaries pale fuscous to
smoky brown, with darker veins and a dusky discal spot. Fringes pale, with a
du.sky interline. Beneath, primaries blackish or smoky, white powdered out-
wardly; secondaries paler, more powdery, with an outer dark line and dusky
discal spot. Expands 1.28 — 1.32 inches; 32 — 33 mm.

Both sexes are before me, the California specimen frotn Mr. Ed-

is a much paler gray and the maculation is more distinct, but there
does not seem to be any other difference, and I can scarcely think
them distinct. I consider the Colorado specimens represented in the
National Museum collection yyjiical of the species and the Califor-
nian as a race.

This genus has a very decided hahital resemblance to Orfhodes,
but differs at once by the naked eyes. The species u]jon which tlie
genus is based has been known to me for .several years. It is in the
collection of the United States National iNluseum, taken as far back
as 1882, and I have received it for name several times. I have tried
to identify it with all genera or species to which it could have been
reasonably referred, but cannot find any description to cover it, nor
do I find it named in any collection thus far examined. It may be
confused under Orthodes cxjnica, to which it bears some resemblance.
I have named the form.
Aiiorf liodes prima n. sp. — General color a soft, even mouse gray. Head
and tliorax immaculate. Primaries with all the lines evident, the basal, t. a.

T. a. line with a decided inward angle on the cell, irregularly oblique below.
T. p. line outcurved over cell, somewhat incurved below; it is even or sli<Thtlv
crenulated. S. t. line yellowish, irregular, as a whole closely parallel to the outer
margin. A vague blackish median shade line, often ditfuse, obtusely angulate
on the reniform, quite rigid below to the hind margin. Claviform wautino-.
Orbicular punctiform blackish. Keniform an indefinite blackish lunule. some-

lection (coll. C. V. R.) and the life-history has been made out.
There should be no difficulty in recognizing this species by the
soft color and single, line median lines. The harpes are broad, up-
curved at tip, a small corneous process at inferior angle, where also
the surface is set with acute teeth ; a stouter and longer corneous
spur from below the middle of the harpe inclined upward and in-
ward, or exactly opposite the other spur.

Triclioelea po*$tica n. sp. — Pale, somewhat creamy white, with a faiut
luteous admixture, powdery. Primaries with all the maculation faintly written,
blackish. Basal line marked on costa by a geminate black spot, and again faintly
below the median vein. T. a. line upright, geminate on costa only, lunulate,
preceded by a variably obvious pale shade. T. ]). line also marked by costal
dots, thence single, crenulated, outcurved over reniform, rather evenly oblique,
or with but a slight incurve below. This line is also accompanied by a somewhat
paler shade, and a series of pale venular dots outwardly. S. t. line marked on

costa, but very vaguely below, becoming in one case scarcely traceable, in the
other fairly detined by a dusky preceding shade. A series of blackish terminal
lunules. Claviform small, imperfectl.v outlined, concolorous. Orl)icular want-
ing, or but faintly indicated, then oval, rather small. Reniform large, upright,
kidney-shaped, laterally only defined, with a central fuscous lunule, which
expands somewhat inferiorly. A vague median shade through the outer part of
median sjiace. Secondaries in the male white, veins fuscous marked ; a narrow
dusky outer margin ; a distinct discal lunule. Secondaries in the female dusky,
smoky brown, somewhat paler basally, fringes white. Beneath white, powdery,
with a variably distinct crenulate outer line and discal spot. Expands 1.40 in-
ches; 35 mm.
Hab. — Denver, Col. (Bruce).
Male ami female are before me, the former from the coll. U. S.
Nat. Museum (two specimens), the latter from Mr. Neumoegen. The
frontal jirotuberance is quite prominent, the armature of the fore
tarsi much as in decepta rather than edwardsil. The male genitalia
are similar to those of the other species, and best described by a
reference to figure 5 on PI. II, with which should be compared also
PI. XXII, figs. 18 and 19, Proc. U. S. Nat. Mus. vol. xii.
Triclioclea aiitica n. sp.
Every word of the description of postica will apply as well to this
species, save that the secondaries of the male are less soiled, more
purely white, and in the female the .secondaries ax'e like those of the
male postica; otherwise the maculation is the same, and I should
have considered the specimens identical, but for the fact that the
frontal protuberance is much smaller, less prominent, the tarsal ar-
mature weaker even than in edwardsii, and finally the male struc-
tures differ quite strongly, first in absolute size, those of the ])resent
species being fully one-third larger from the same sized male and
also in the arrangement of the corneous claspers, which differs from
all of the other species, and is figured on PI. II, fig. 4. Expanse
as in postica.
Hab. — Los Angeles County, Cal., April 10th ; good specimens are
in the National Museum collection (through C. V. Riley).
Tteniocaiiipa orobia Haw.
This insect I could not find in the INIeske collection, from which
it was described, when I wrote my Revision (Proc. U. S. Nat. Mus.
xii, 455-496, 1889). The completed incorporation of the collection
into the regular museum series has bi’ought to light the typical Texas
specimen, and it turns out to be exactly like specimens of oviduca,
NORTH AMERICAN LEPIDOPTERA.

to which it must be cited as a synonym. Mr. Grote claims credit
for Dr. Harvey’s descriptions, and he must be charged with this
synonym.
T. pacifica Harv.
The museum has received, tlirough Dr. Riley, four specimens of
this species from Alameda County, Cal., January, February and
March, and with the red number 334. The specimens are all males,
and confirm the opinion that we have to do with a good species and
not a variety of the eastern form. The characters pointed out by
me hold good, save that the orbicular may be as dark as the reui-
form. As the whole the specimens look more robust and are darker,
more powdery.
Ta^iiiocainpa aiiutiliinaciila n. sp.— Ground color pale fawn gray; a
fine soft tint. Head and thorax immaculate. Primaries with basal and t. a.
lines wanting. T. p. Hue a curved series of small venular dots. S. t. line rather
irregular, concolorous or slightly paler, marked by a somewhat darker preceding
shade (rarely the line will be entirely wanting). A narrow median shade line,
bent on the reniform, also sometimes wanting. Orbicular concolorous, usually
obsolete, sometimes outlined by ferruginous scales, moderate, round. Eeniform
large, upright, concolorous, more or less completely defined by a rusty red-brown
annulus, always distinct at the outer side at least, and forming the only obvious
bit of maculation on the entire wing. Secondaries very pale powdery fawn gray,
with a faint, darker, discal lunule. Beneath pale, powdery fawn gray ; primaries
with a discal dot and a more or less evident, sometimes obsolete outer line. Sec-
ondaries with a distinct discal spot. Expands 1.68 inches ; 39 — 42 mm.
Hab. — Texas, February 17th, 19th and 25th (Belfrage).
Five good specimens are in the National Museum collection ('coll.
C. V. R.). The antennae of the male are lengthily bipectinated, the
habitus and wing form as in my pectinata, to which this species is
allied. The very pale fawn gray color, the lack of all prominent
maculation, save the rusty ring to the reniform, and the plump, woolly
thorax, will readily identify this form. It bears a casual resemblance
in habitus to Copipanolis, and the assignment of the specimens to
that series by the collector caused me to overlook them in my studies
on the Museum material previously.
The male characters are distinctive. The harpes narrow toward
tijh which is somewhat drawn out superiorly into an acute point. A
stout, curved, corneous process frojn the middle of the outer third, a
smaller process at its base inferiorly and a longer stouter curved pro-
cess from behind the middle of upper margin.

Tioiiiooaiiipst lrifas<*ia n. sp. — Head and collar pale, whitish ocheroiis,
this ])ale tint extending along the costa of primaries. Color else a powdery red-
dish ocher. Primaries more or less dusted with black scales. Basal line pale,
mostly lost in the pale costal region. T. a. line broad, ]iale regularly outcurved,
even. T. p. line broad, pale, even, outcurved on costa, then inwardly very ob-
li(iue and only very slightly incurved. S. t. line broad, pale, outwardly diffuse,
inwardly defined by a powdering of dark or black scales. A series of small
terminal lunules. Fringes with a series of black points. A broad, variably
distinct shade of black scales through the outer part of median space. A series
of black venular dots through s. t. space. Claviform wanting. Orbicular round
or oval, small or moderate, pale ringed and dusky centered. Eeniform upright
oval, more or less evidently black powdered. Secondaries white. Beneath white,
with a faint ocherous tinge. Expands 1.08 — 1.20 inches; 27—30 mm.

I notice that, by some accident, group palilis is omitted in my
Revision of Tteniocampa, though the characters of the group are
given.
One pair is in the coll. U. S. Nat. Museum ; others are in Mr.
Bruce’s hands.
Tieiiioeampa pectiiiata Smith.
When I described this species, from scant material, there was a
rubbed and faded male s])ecimen in the coll. U. S. Nat. Mus., which
I identified with this form, and from which the figure of the sexual
characters was made. Since that time new material has been re-
ceived, and I have described the genus Perigonica, to which I find,
on renewed study, the supposed T. pectlnata belongs. A number of
fresh, clean specimens of the latter enable me to give a correct figure
of the sexual characters, and for comparison I add the figures of
Perigonica angulata and P. falminans, all from typical specimens.
See PI. II, figs. 7, 10 and 11.
PERIGR.iFHA Led.
This genus, among others, was monographed, our American species
alone considered, in the Proc. U. S. Nat. Museum xii, 490, and I
there called attention to the fact that our species did not in all re-
spects agree with the European tyjies. I have since received a speci-
men which fills all the requirements of the generic description, and
i\Ir. Edwards’ genus Strefchia, which antedates iMr Orote’s name
NORTH AMERICAN EEPIHOPTERA.

.4cemf, must therefore be used for the species heretofore referred to
Perigrapha .
The genus Perigrapha will he re])resented in our fauna by
I*, priina ti. sp. — Deep bluish asli-gray, with a fuscous powdering. Front of
head and base of collar discolorous yellow fuscous; patagise obscurely black mar-
gined B;isal line obscurely marked, scarcely traceable. T. a. line geminate,
fuscous, evenly oblique outwardly. T. p. line geminate fuscous, interrupted,
quite faint, evenly bisinuate. A vague, narrow fuscous shade through the centre
of the median space. Costal half of basal space paler ash-gray. Claviform
wanting. Ordinary spots large, subequal, oblong, oblique, touching, but not quite
confluent inferiorly, narrowly fuscous margined, filled with paler gray, reniform
somewhat stained with reddish. Beyond the middle of the s. t. space the wing
is much paler gray, contrasting asiainst the bluish of the rest of the wing; the
irregular faint s. t. line traceable by a powdering of black scales. A series of
blackish terminal lunules. Secondaries even, smoky fuscous. Beneath, smoky
brown, secondaries pale powdered, both wings with an outer line and discal spot.
Expands 1.20 inches; 30 mm.
Hah. — Sierra Nevada, Cal.
A single female specimen from Mr. Hy. Edwards in which the
antennte are lengthily serrate or very shortly pectinated.
The large ordinarv spots and discolorous pale terminal space,
combined with the generic characters, will render this species easily
recognizable. \ \
Strotcliia variabilis n. 'sp. -Ground color dark ash-gray with black
powderings. Head and front of collar umber brown, collar wdiite tipped, with a
crested black line. The small thoracic tuftiugs and the abdominal tufts blackish
brown to black. Abdomen dark fuscous. Basal line geminate black, evident.
T. a. line pale, geminate on costa, obliquely and regularly outcurved to vein 1,
and agaiT) outcurved below that vein. T. p. line rather indefinite, inw'ai’dly de-
fined by a variably distinct lunate black line, wddely outcurved over cell, and as
deeply incurved below, so that the median space on inner margin is only half
the width through the cell. This median space may be coucolorous, only slightly
darker, bright umber-brown, or almost black. The claviform is w'anting. Or-
bicular large, rather irregularly oval, oblique. Reniform large, kidney-shaped,
both the spots narrowiy black ringed, almost coucolorous, suffused with reddish,
or nearly white, contrasting. S. t. line powdery gray, irregular, vague, marked
opjiosite the anal angle with a more evident blackish lunule, follow'ed by ocher-
ous or paler yellow scales. S. t. space slightly darker costally. A series of small
terminal dots, beyond wiiich the fringes are cut with pale gray. There is a short,
curved basal black Hue which does not extend to the t. a. line, and the veins are
all black marked. Secondaries whitish, quite heavily black powdered, with
.soiled veins, a blackish discal lunule, and a blackish marginal line. Beneath
pale, with black powderings, the primaries darker, both wings with a dusky
outer line and discal lunule; secondaries also with a marginal line. On the pri-
maries the outer line is not complete and may be entirely wanting, and the discal
spot varies in size and distinctness. Expands 1..52 — 1.(10 inches ; 38 — 40 mm.

JOHN B. SMITH.
Several specimens are before me from Mr. Jseumoegen and Mr.
Bruce, and n<) two of them are alike. One male bears a deceptive
resemblance in maculation to Valeria grotei, the dark color and con-
trasting white ordinary spots causing the likeness, others have a very
decided reddish suffusion through the median space and some are
entirely concolorous, even, blackish gray.
The ordinary spots are sometimes well separated, usually quite
close together, rarely confluent inferiorly. The vestiture is scaly,
and in appearance the species is associated with my first group in
which the ordinary spots are usually fused. It is readily distinguished
from all. The male genitalia are unlike the others of the genus.
The harpes are narrow, the tip somewhat produced superiorly. The
clasper consists of a corneous hook with a basal short s])ui\
belirensisina Grt.
This species, unknown to me in 1889, I have identified in speci-
mens sent me by Mr. Edwards for name. It agrees well with the
description, but varies excessively in distinctness of maculation, in
ground color and in the amount of black powdering. The sexual
characters are unlike any figured in my Revision (Proc. U. S. Nat.
Museum xii, pi. xxii, figs. 1-5), but resemble most nearly those of
normalis, save that the clasper is double.
In the Verb. k. k. zool.-bot. Gesell. in Wien, 1872, p. 502, Zeller
describes Sedenia (cavifrous) blundulalis, a Pyralid. He says of it:
“ Frans conica, superne cornea, excavata," using this character to ally
it with cervalis. The specific diagnosis is short and characteristic :
■■ Alls albis, anterioribus serieeis, strigis duabus crassis, undulatis, nigris
$ .” The description is full and careful, and, in connection with
the figure given on pi. iii, fig. 1-f, leaves no doubt that the s])ecies
before me is really that intended by Zeller. The locality, Texas, is
also identical. Mr. Grote has omitted the genus, and apparently the
species as well, in his List of 1882. A few days ago Mr. Hulst
handed me the insect, with the remark that Prof. Feruald said it
was a uoctuid. A glance at the habitus convinced me that this was
so, and that I had a close relative to some forms which had been in
my hands for name for some time. Zeller’s description points so
convincingly to a Pyralid that it could leave no feeling of doubt on
the reader. He says, among other matters, that the maxillary palpi
are small, brown, resting on the labial pal[)i. An examination of
my specimen shows a curious error, induced probably by the con-
NORTH AMERICAN LEPIDOPTERA.
]21
viction that the species must have maxillary palpi. As a matter of
fact the supposed palpi are merely the projecting and somewhat
thickened edges of a Hat, plate-like clypeal process, arising below
the frontal tubercle. The single ? possessed by Zeller must also
have been rather imperfect, since he failed to note the fact that the
fore-tibipe were armed at tip with a long inner and shorter outer
spine or claw, though the color and structure are otherwise accurately
described.
Referred to the Noctuidie the relation to Antaplarja sexseriata Grt.
is at once obvious, and to this genus Zeller’s species must be referred,
as A. biundulata Zell. It differs from the described species in the
presence of the clypeal plate below the tubercle, but this will scarcely
warrant generic separation. From A. sexseriata, which it closely
resembles in maculation, it differs in the somewhat heavier bands,
and in the absence of the subterminal black dots.
THYREIOK n. geu.
Body plump, robust, thorax with thin hairy vestiture. Head re-
tracted, front flat; palpi short and weak, scarcely exceeding the
front; tongue moderate in length ; antennae of % stout, rather short,
with short, thick lateral teeth. Tibiie spinose, clothed with i-ather
long thin hair ; anterior pair abbreviated, broad at tips, with a single
long inner claw, and a series of two or more along the outer edge.
Primaries proportionately short and small, the co.sta concave, apices
somewhat drawn out, outer margin oblique, scarcely convex out-
wardly.
d'his genus is to replace Aedophron as used by Mr. Grote. I
pointed out eight years ago that Mr. Grote’s species snowi could not
be referred to Lederer’s genus, but as I had no specimens I made no
change in the reference. Mr. Grote, in his List of 1890, has made
no change in the generic location of the species, though he has based
a number of new genera on characters pointed out for him by others.
The occurrence of a new species, close to snowi, enables me to give
the above description. The genus Aedophron retains as its single
American representative, Tepper, differing from the European
representative as already pointed out by me.
Th. rosea .sp. nov. — Head and thorax a rather sordid pale lemon-yellow;
abdomen deep blackish gray. Primaries above, yellow to the s. t. space, thence
rosy red to the outer margin, receiving an admixture of yellow outwardly;
fringes pink ; a ray of rosy red extends through the cell, joining the marginal

interspace, also joining the marginal hand. Secondaries above, a deep blackish
gray, with pale rosy fringes. Beneath, primaries deep blackish gray; seconda-
ries paler, flushed with pink aloiig the costa, and a very decided rosy shade ex-
tending from the apex along the outer margin nearly to the anal angle. Expands
1 inch : 25 mm.
Hab. — Colorado (Bruce).
The single male from which this description is made is from Mr.
Neumoegen’s collection, hut I think I have seen others, also of Mr.
Bruce’s collecting, from the same locality. The species should not
he difficult to identify.
XAMTHODES Gn.
A somewhat peculiar genus, resembling in its form and habitus
Chariclea and Aedophron, but didering in venation, form of palpi,
etc. Of medium size, slender, the entire insect somewhat depressed ;
front with a smooth, horizontally [irojecting conic tuft; tongue spiral.
Eyes large and naked, anteniue thin, bristle-form, in the male with
short fine ciliie. Palpi slender, apparently, from the smooth close
vestiture, of equal thickness, converging, somewhat upcurved, then
projecting in the form of a snout beyond the palpi. Collar convex
close to the dorsum and through the fine hairy vestiture scarcely to
be distinguished from it. Abdomen smooth, with thin vestiture.
Legs strong, unarmed and closely scaled, only the outside of the
tibiie with dense, woolly, thick hair. Primaries without accessory
cell, 6, 7-8 and 9-10 out of the tip of the median cell ; broad, with
feebly arcuate outer margin. Secondaries with vein 5 weak.
The above is a close translation of Lederer’s description of the
genus which has been introduced into our fauna by Mr. Grote for
his species Schinia buxea; the genus Trileuca being [iroposed for
Schinia rectifascia and S. gnluare Strk. In the “ Revised Check
List” S. gubuire is referred to Lygranthcecia, to which it does not
belong, while buxea and redifacla go into Trileuca and are refei’red
to the Acontiiiue. S. gulnare Mr. Grote did not know, and was, of
course, justified in leaving it where its author put it. Trileuca may
be a good genus, but it does not belong to the Acontiiiue. Its rela-
tions are with Calynuiia. and Cosinia, or perhaps very near to Atethmia.
Xanthodes, as based on the Eui’opean type, is unlike either of the
species associated with it by IMr. Grote, and I do not know of any
American species that could be properly referred to it.
Mr. G rote makes a very touching plea for his genus Lygranthcecia
in the Proc. Am. Philos. Soc. 1888, 173, but does not show anywhere
NORTH AMERICAN LPHHDOPTERA.
123
that it has any right at all under the laws of priority. Mr. Grote
has always been a strict Hiibnerian, but now, when one of his genera
is to be superseded, it becomes “ unjust and against the usual comity
and practice !”
But even suppose Hiibner’s genus should not be adopted, how can
we get over Guenee’s genus Tamila proposed in 1852 with nundnia
as the type? One of the very species which Mr. Grote now includes
under Lygraathoecia ! and why, if “comity” is to be shown, should
Boisduval’s Anthcecia be sacrificed, the very first sjiecies being Mr.
Grote’ s present type of Lygranihcecia. To be sure the designated
types of Anthcecia and Melicleptria are the same, but “ comity” would
seem to re<juire that Anthcecia should be retained for some species if
possible. And why should Hiibner be enforced against Boisduval
and not against Grote?
For the present I cannot see my way to the use of Lygranthcecia
in preference to Schlnia or Tamila.
Before describing the species of Schinia before me, an ally of
Schinia (Trileuca) buxea merits attention.
Trileiica, deiitalis n. sp. — Head, thorax ami primaries a bright glistenins
lemon-yellow; transverse lines of primaries hrown. Basal half line faint. T. a.
line well removed from base, with a long outward angle on median vein. T. p.
line acutely angulate outwardly, the spur reaching the outer margin below the
apex. S. t. line also with an outward angle, reaching the outer margin at the
same point with the t. p. line. A small, geminate black dot on costa, just before
the apex. Between the point at which the angulation of the outer lines touches
the margin and the anal angle, a metallic coppery brown shade fills the space
beyond the s. t. line. Secondaries pale yellow, ocherous, more whitish basally.
Beneath yellow, powdery, immaculate, the secondaries whitish towards inner
margin. Expands 1.40 inches; 35 mm.
Hab. — Southern Texas
A single sjtecimen from Mr. Neumoegen’s collection is before me.
It has much the same color as buxea, but is larger, the course of the
lines is different, and there is the cojipery brown outer shade, -which
is distinctive. In maculatioii and color this is remarkably close to
Guenee’s Xanthodes traiisversa from India, so close, indeed, that had
the species been described from America I had considered the differ-
ences within the range of specific variation.
Lys;raiithcecia pariiieliana Hy. Edw.
To the kindness of Mr. Schoenborn I owe a sight of the type. It
has the wing form, and exactly the macnlatioii of nundina, but the
ground is ocher yellowish, the lines white, and the dark markings

are umber-brown, with an olivaceous slieen. The secondaries are
yellowish at base, with a broad blackish outer margin. The tibial
armature consists of two long inner and three shorter outer claws or
spines, referring to constricta, brevis, errans and the small species near
the foot of my series, with which this form has nothing in common.
It is undoubtedly a good and quite remarkable species.

This species is now represented in the Museum collection by sev-
eral specimens. It was not known to me in 1883, when I published
my revision of the Heliothini, but was found in the Belfrage material
which came to the Museum. Mr. Edwards kindly gave me a speci-
men of his species, now also in the Museum, and this enabled me to
make the above synonymical reference.
The sjiecies has the structural features of Schinia lynx and its type
of maculation, replacing the yellow by bright red throughout.

^icliiiiia sexplagirtts* m sp. — Head and thorax dark olivaceous greenish
gray. Primaries pale, powdery greenish gray, basal space and costal and mar-
ginal patches in s t. space dark, olivaceous, of the same tint as thorax. Basal
line marked on costa only. T. a. line pale, well marked, forming a very even
and regular outcurve. T. p. line even, i)ale, narrower than t. a. line, evenlj’
outcurved over the cell, and as evenly though less prominently incurved below.
S. t. line pale, not so well mai-ked as the median lines, a little irregular and
holding a middle between t. p. line and outer margin in course. A pale line at
base of fringes, which are concolorous, interlined with pale. The s. t. space is
slightly dai’Ker than ground color, except on costa and internal margin, where it
is of the same color as the basal sjiace. A vague, dusky, median shade over the
reniform, bringing this spot into view as an u])right dusky patch not definitely
margined. There is a vague suggestion of an orbicular. Secondaries white,
with a blackish discal lunule and outer margin, the latter with a white central
shade, more prominent toward anal angle; fringes white. Beneath whitish,
tinged with faint olivaceous, both wings with a narrow outer line; primaries
with black, contrasting reniform and orbicular. Expands 1.04 inches; 26 mm.

The front is globose, bulging; fore tibije with a long inner and
two shorter outer s])inules. This species is allied to hiundnlata in
general appearance, but differs widely in details. The wdiite secon-
daries, the contrasting shades of primaries, and conspicuous ordinary
spots of the under side, are all good distinctive features. A single
good male is in the collection U. S. Nat. Museum, from INIr. BiTice,
and this is the type.
KcliiiiiR brucei Smith. — Ground color of head, thorax and primaries, a
pale luteous, varying in intensity, the maculation varying from ocheronsto rusty
yellow. Basal line marked on costa, the basal space deepening in color outwardly
to tlie t. a. line, where it is of the richest tint found on the wing. T. a. line
pale, whitish inwardly sharply defined by black scales, outwardly diffuse, shading
into the ground color of the median space. T. p. line pale, whitish, regularly
Insinuate, crenulate and very narrow, sometimes even interrupted opposite the
cell ; outwardly marked with black scales. S. t. space ocher or rusty yellow
brown, sometimes even of an olivaceous tinge. S. t. line pale, broad, diffuse,
either evenly parallel to outer margin, or indented opposite the cell, .sometimes
almost cutting the s. t, space. Terminal space slightly darker than ground color.
A series of small, terminal, blackish dots. Fringes concolorous, with dusky
terminal dots. A deeper shade of ground color through outer part of median
space, narrowed to a line at the hind margin. Reniform large, dusky, with
blackish lateral margins, not completely defined; no orbicular. Secondaries
whitish, with dusky outer margin, interrupted by an irregular whitish shade
behind middle, a moderate discal s]iot and white fringes. Beneath whitish, with
maculation of upper side incompletely reproduced, powdery; primaries with
orbicular and reniform usually very distinct. Expands 1.00— 1.20 inches ; 25 —

or tan color. A well defined, moderately broad, even band at basal fourth, the
outer margin at about the place usually occupied by the t. a. line. A broader,
less definite median fascia, the color less intense, the band broadest at its middle,
narrower at inner than at costal margin. A moderately broad fascia of even
width, its course slightly sinuate, occupies w’hat is ordinarily the s. t. space. A
half band starts from costa at apex and tapers out at about the middle of outer
margin. A darker line at base of tbe white fringes. Claviform and orbicular
wanting. Reniform consists of a brown lunule at end of cell, followed by a
small spot of the same color just beyond. Secondaries white, shading to ocher-
ous outwardly. Beneath yellowish white, jirimaries with a suhmarginal deeper
fascia, leaving marginal space somewhat contrasting white. Expands .92 inch.;
23 mm.

Cal. In dowers of Proximma callfornicum.”
Two specimens in the National Museum collection (through C. V.
Riley), neither of them in good condition, hut together making a
very perfect whole. The species has the ground color of cuniatilis,
and the ocherous fascite of chrysellus, hut is utterly unlike either in
type of maculation. The front is protuberant, bulging, but not
rough, and the armature of the fore tibiie is comparatively weak
and consists of a long inner spine, and a series of shorter outer spines,
much as in cumatilis, but less claw like.
One specimen has a red ink number 181, which indicates a biolog-
ical note on the species, in Dr. Riley’s posse.ssion.
Kcliiiiia uni macula n. sp. — Head, thorax and primaries white, markings
of the latter of a faint olivaceous clay yellow. Primaries with a broad, curved,
sub-basal band, the outer margin limiting the t. a. line, which is followed by a
few .scales of the same color as the hand, indicating its outer margin. Outer
portion of median space and all of s. t. space of the same faint olivaceous tint,
through which the white t. p. line is evident, starting in a broad costal patch,
narrowing to a mere line in its outward curve over the cell and becoming more

obvious on the incurve and at the inner niarfiiji. S. t. line marked only hy the
difl'erence in shade between terminal and s. t. space. This difference is very
strongly marked at the costa, then the s. t. space is almost divided by the white,
and thence the dark color again widens with an outward curve the division not
sharjily marked. A row of black terminal dots. Base of fringes olivaceous.
Eeniform upright, dark, constricted inferiorly, black marked, and more dilated
than superiorly ; no trace of orbicular. Secondaries white, with a dusky discal
•spot and indefinite outer border, in which is an ovate white spot. Beneath white,
with the maculation of the upper side faintly reproduced. Expands 1.04 inches;
26 mm.
Hab. — Colorado (Bruce).
Tills is a close ally of <S'. vanella, which it resembles completely in
habitus and structure. It differs obviously in the entire lack of the
orbicular and claviform in the much smaller reniform and in a gen-
eral softness of tint and maculation not noted in its eastern congener.
The type is from Mr. Neumoegen’s collection, and there are three
handsome examples in the collection U. S. Nat. INIuseum, all of Mr.
Bruce’s collecting.
biciispida n. sp. — Head, thorax and primaries luteous. Prima-
ries with maculation darker, more olivaceous, and with an admixture of black i.sh
scales. The transverse lines are all of the palest shade of the ground color, and
defined by the difference in shade between tbe adjoining spaces. T. a. line with
a long outward cusp on the median vein, and a deep incurve below the internal
vein. Basal space dark, with a pale cusp on the costa, and with a strong admix-
ture of black scales along inner margin, tbe internal vein pale. S. t. line regu-
larly bisinuate, even, oblique, well defined tbroughout. S. t. space quite strongly
speckled with black scales, especially along the outer margin defining the s. t.
line. This latter is deeply and suddenly incurved opposite the cell, then ap-
proaches quite close to the outer margin, again indented nearly opposite the anal
angle. A row of small blackish terminal spots, from which proceed blackish
shades cutting the fringes. Orbicular wanting. Reniform moderate, blackish,
quite indefinite; median s])ace crossed by a diffuse dusky shade, faint through
the centre, but spreading out and occupying nearly the entire width of the me-
dian space inferiorly. Secondaries black, with a broad yellow median band,
divided by a large black discal spot; fringes yellow. Beneath, primaries pale
yellow, with a broad basal shade, a large discal spot, and a broad subterminal
baud black ; secondaries white, with an incomplete outer band and discal lunule
black. Expands .96 inch. ; 24 mm.
Hub. — Southern Texas.
The anterior tibia has two stout inner and five stout outer claws,
and it is therefore related to pucku7'dii, morhia and nobills. From
all of these it difiers in the course of the transverse lines, and the
more decided contrasts in maculation. A single specimen from Mr.
Neumoegen’s collection is before me.

Kchiilia eonc*iiiiia u. sp. — Head, thorax and ground color of luiniaries a
rather deep luteons, with an olivaceous tint. Primaries maculate with a rather
deep, almost chocolate-brown. Basal space brown, deepest at the t. a. line, and
merging into the ground color at the extreme base. T. a. line white, prominent,
outwardly oblique in two curves to median vein, then inwardly oblique in two
further curves to hind mai-gin. T. p. line white, rather strongly and quite
evenly bisinuate, well marked, excejit over the cell, where it is interru]>ted and
imnctiform; outwardly it is marked with black scales. S. t. space darkest at
1. p. line, lightening somewhat to s. t. line, which is very irregular and marked
only by the contrast between the dark s. t. space and the terminal space, which
is of the ground color. Fringes of ground color with a series of darker terminal
dots. Orbicular wanting ; reniform large, dark, somewhat indefinite, obscured
by a dusky shade, which crosses the median space and merges into the ground
color at either margin. Secondaries obscurely tawny at base, becoming black at
outer margin. Fringes pale luteons, almost dirty white. Beneath tawny, prima-
ries with disc black, sending up an ante-apical si>ot of same color ; a black discal
spot. Secondaries with a large discal spot and a deejier, brownish black outer
margin. Expands .9(1 inch. ; 24 mm.
Hdb. — Southern Texas.
This s])ecies has two inner and three outer claws to the fore-tibia
and is most nearl}^ related to brevis Grt. The contrasting white
lines, the olivaceous luteons ground color and the course of the lines
are difierent ; brevis seems not to have the broad median shade. A
single specimen from Mr. Neumoegen.
Scliiiiia digitalis n. sp. — Hesd, thorax and primaries a itowdery luteons
gray. Primaries with basal and s. t. space darker, with an admixture of blackish
scales; median lines narrow, pale. T. a. line evenly oulcurved, the curve greatest
in the cell. T. p. line very narrow, and but very little sinuate, almost rigidly
oblique. S. t. line marked by the diflereuce in shade between s. t. and terminal
space, strictly parallel with the outer margin. Fringes dusky. Secondaries a
pale yellowish gray with a more blacki.sh outer margin and very faint discal
blotch Beneath, primaries dirty gray, with a faint reproduction of the outer
lines of upper side, and a dusky discal spot; secondaries much as above. Ex-
pands 1.20 inch. ; 30 mm.
Hab. — Dallas, Texas.
This species has heavy inner and four heavy outer claws to the
anterior tibia, and is therefore related to thoreaui and rivulosa, from
which it differs radically in the coloration. It is the only species
with the heavy armature which has this luteons gray, almost greenish
tinge. It hears a deceptive resemblance to gracilenta, and the mark-
ings, indeed, are almost exactly like it.
A single specimen only at hand, hut I feel (juite certain that it is
in other collections as a faded gracilenta.

Sohinia biiiiKliilata n. sp. — Head white, with a faint olivaceous tinge,
much more marked on the thorax ; abdomen fuscous. Primaries a faintly green
luteous or olivaceous, the terminal space slightly paler, else almost uniform in
tint. The median lines are very distinct, broad and white; the t. a. outwardly
curved and inwardly marked by a few black scales ; t. p. S-shaped, or strongly
hisinuate, outwardly relieved by a few black scales. Fringes whitish, uniform
in color. Secondaries faintly olivaceous, pale, with an indefinite dark outer
hand, and a dusky discal spot. Beneath, primaries silver-gray, with the costal
and outer margin narrowly yellowish. Secondaries white, with a faint discal
spot. Expands .92 inch. ; 23 mm.
Hab. — Colorado (Bruce).
This haudsoiiie and strongly marked species is allied in structural
characters to trifascia or cumatiiis, and is very distinct from anything
I have seen.
The single specimen before me is from Mr. Nenmoegen’s collec-
tion, and I do not remember having had others.
Scliiiiia simple.^ n. sp. — Head, thorax and primaries of a glistening, pale
green color; immaculate. Secondaries a very faint ocher yellow, with an in-
definite dusky discal spot, and a dusky outer margin, not extending more than
two-thirds from apex to anal angle. Beneath, a glistening, pale yellowish white,
with an indefinite blackish discal spot on all wings. Expands 1.20 — 1.28 inch. ;
30 — 32 ram.
Hab. — Colorado.
This species has a single long inner and three feebler outer, claw-
like spines to the fore tibia, and it belongs to the series with trifascia
and gracilenta, from all of which it differs in the immaculate prima-
ries. The specimens were collected by Mr. Bruce, and are distributed
in a number of collections, including that of the U. 8. Nat. Mus.
The specimen before me is marked “ Denver, Light, July 21, 1887.”
In the two specimens in the Museum collection, one, marked
“ Foot-hills, Colo.” has entirely immaculate secondaries; the other
specimen is much deeper in color throughout, and the marginal black
band is much more distinct, and is complete, extending also along
the costa.
Scliiiiia ci'Oiiilinea. u. sp.— Head and thorax yellowish white, the thorax
with an admixture of ouherous scales. Primaries whitish, with a strong ad
mixture of ocherous, the maculation with a brown admixture to the ocher. A
broad sub-basal, dusky band, outwardly limited by the white t. a. line, which is
outwardly curved and irregularly denticulate on the veins, the widest outcurve
in the submedian interspace. Inwardly this line is marked by a few black scales,
outwardly it is indefinite. T. p. line white, outwardly defined by black scales,
crenate, with distinct outward spurs on the veins, its general course feebly bi-
sinuate. S. t. line marked by the difierence between the brownish s. t. space

and the even faintly oclieroiis white of the terminal space. S. t. space strongly
constricted opposite cell, less so in the s. in. interspace. A row of very faint
terminal dots. An upright dusky median shade, fading gradually to the ground
color in each direction. Reniform an indefinite, upright, dusky line. Seconda-
ries pale with a faint reddish tint deepening to a coppery red outer border. Be-
neath, quite uniform co]>pery red, the secondaries paler basally, primaries im-
maculate. Expands .92 inch. ;23 mm.
Hab. — Southern Texas.
This, in its structural characters, resembles spinosce, and in appear-
ance is allied to sejicirata and saturata, the latter of which it resem-
bles in the crenulate median lines and general tendency of maculation.
I presume this would be a Eupanychh according to Mr. Grote, if its
relation to spinosce be a generic character.
Heliophaiia obliquata n. sp. — Head and thorax a rather deep clay-
yellow, with an olivaceous tinge, alinost tawny; abdomen blackish. Primaries
above an olivaceous, dark luteous, marked with a somewhat rusty red-brown.
There is no distinct t. a. line. An oblique brown shade band extends from the
inner margin near base to the end of the median cell, joining the upright some-
what indefinite reniform. From this band a spur of the same color is sent to
the base along the internal vein, and another along the median vein. A narrow
streak runs also through the cell to the reniform. T. p. line concolorous, even,
entirely parallel with the outer margin, marked by a very narrow, indefinite.
l)recediug brown line, and followed and defined by the brown s. t. space. S. t.
space uniformly brown, marking the s. t. line by the contrast between it and the
terminal space. This line of contrast is irregularly bisinuate. A brown terminal
line at the base of the concolorous fringes. Secondaries black, mingled with the
tawny yellow basally, the fringes tawny. Beneath, primaries black, costal and
outer margin tawny, the former allowing part of a black discal mark to be visible.
Secondaries with co.stal third and centre tawny, else black. A large black discal
spot. Expands .75 inch. ; 19 mm.
Hab. — Texas (Neumoegeii).
I have had several examples of this little species for determinatiou,
some of them I thiuk from Colorado, but have not named it any-
where. The characters agree well with those of the genus as given
by me (Trans. Am. Ent. Soc. x, 240). It is not impossible that this
is an extreme variety of Mr. Grote’s species, but both upper and
under side differ from the description and from the specimens I have
seen. In mitis the ground color is dark, while in the jiresent species
it is pale ; but this reversal does not necessarily indicate absolute
difference.
Ileliopliaiia amaryllis n. sp. — Head, thorax and abdomen black, with
fine, thin, loose, divergent, pale yellowish vestiture. Primaries a dirty grayish
brown, median sjiace a dirty yellowish white. Basal line distinct, whitish, mar-
gined by black. T. a. line whitish, i)receded by a black, and followed by a dark

gray shade ; in course it is obtusely angulate on the median vein, and in the
slight convexity in the cell, the round orbicular rests on the line. T. p. line
whitish, even, widely outcurved over the cell and incurved beneath: defined
outwardly l>y the dark ground color, inwardly by a narrow gray-brown line.
The reniform is large, black, filling the entire width of the cell and resting on
the incurve of the t. p. line. A narrow dusky shade from the reniform to hind
margin close to t. p line. Beyond the t. p. line the wing is uniform in color,
somewhat white marked on the veins and crossed by the narrow whitish s. t.
line, which is twice outcurved and with three acute inward teeth. Secondaries
black, with a broad whitish hand, almost divided by the large black discal spot,
Beneath, primaries white, with a broad, irregular, black outer border, a broad
black basal dash, and a large black reniform. orbicular and subapical spot. Sec-

Hah. — Colton, Cal.
I have seen but a single specimen of this curious insect, received
from INIr. W. N. Tallant, Columbus, Ohio, marked collected by G.
R. Pilate. It has the habitus of Melieleptria, but the structure of
the genus to which I have referred it.
STYLOPODA n gen.
Eyes narrowed, ovate, naked. Head small, not retracted, front
somewhat protuberant, conical, but not roughened. Tongue strong,
moderate in length. Palpi reaching to middle of frf)Ut, stout, the
terminal joint small, the parts so held as to make the front seem
pointed. Anteniue moderate in length, in the S finely ciliated.
Thorax plump, robust, vestiture scaly, smooth, forming an indefinite
posterior tuft. Legs short and stout, tibiie not spinose, the spurs
long, clothed with long, divergent vestiture, anterior sho)-t, broad,
flattened and corneous at tip, with a long inner and short outer claw-
like spur or process. Abdomen short, conic, nntufted. Primaries
short, broad, costa somewhat de|)ressed, making the apices prominent.
This genus resembles Pseudotamila in structure, save that the tibiie
are not spinose, and the primaries have the costa de|)ressed. Its
characters are also like F.^eudacontla, save that the eyes are narrow,
ovate. The genus is recognizable, and unlike any other of our
Heliothid foi'ins known to me.
Ktylopoilsi eeplialica !i. sp. — Head, thorax and abdomen deep piir])li.^h
blaek. Primaries purplish hlack to t. p. line, then an irregular white shade
fading into the black ground color beyond. The macnlation on the inirjtlish
ground is picked out by deep black scales. Basal line single, complete. T. a.
line .single, fine, upright or slightly oblique, very regularly tridentate. T. p. line
single, outwardly oblique from costa over reniform. then very deeply indrawn.

UHTrowine; the median space by fully one-half below vein 2. This line is em-
phasized by the pure white following shade, which is broadest in the suhmedian
interspace, white scales — seeming bluish on the back ground — extending through
the subterrainal space and on costa, vaguely indicating the s. t. line. An inter-
rupted black terminal line. Claviform apparently wanting. Orbicular moderate,
concolorous, round, black-ringed. Eeniform incomplete, apparently only the
inner margin defined, the outer merged in the white shade. Secondaries black,
with white fringes. Beneath black, primaries with an interrupted white baud.
Expands .68 — .72 inches; 17 — 13 mm.
Hab. — California.
Two specimens ( 9 ) are in the National Mnsenm, one from my
old collection, the other “ through C. V. Riley, 1888," collected by
Coquillet. The latter is perfect so far as maculation goes, but the
legs are deficient. The former is somewhat rubbed, and has no legs
at all.
This is a strongly marked form which there should not be any
difficulty in recognizing.
There is a single male specimen from my collection in the Museum,
also from California, which is congeneric, but which is almost too
poor to serve as a ty]>e. The [)rimaries above have been rubbed
almost bare of scales, and no maculation is traceable. The secon-
daries are black. Beneath, the primaries are carmine-red, the secon-
daries black. If this is in any collection, I should like to get good
specimens.
l*seii<lacoiitia cru»itaria Morr.
A specimen of what 1 take to be a form of this species is in the
National Museum collection, from Mr. Bruce. It is like the type in
)>attern of maculation, but the black is replaced by an ocherous
brown on primaries, and the median white band of secondaries
broadens and becoming inwardly diffuse, lightens the base. The
type is from Nebraska, and I have seen no other specimens. It may
be we have to do here with another species, but without more ma-
terial I prefer to leave it as a geographical race or form.
Mefopoiiia macula sp. nov. — Head, thorax and primaries orange-yel-
low. Head and collar with an admixture of brown. Primaries with a purplish
blotch filling the base of discal cell, and narrowly connected along the median
vein with a darker, irregular blotch, whose outer margin is about where the t.
p. line should be were it present; a small, irregular spot, marks the location of
the accessory cell. The inception of the s. t. line is marked by a small, some-
what ferruginous preceding patch, and below that by a series of four or five
irregularly separated venular dots. Two dots below the basal purple blotch mark
the t. a. line. Fringes cut with purplish. Ordinary spots entirely obsolete.

Oltviously distinct, from the described species by the black secon-
daries with contrasting yellow fringes. The clypeal structure is a
cup-shaped depression, from which rises a cylindrical projection also
cupped at tip. Specimens taken by Mr. Meeske are in the collections
of Neumoegen and Hulst.
ACJROTirHII.A Grt.
This genus was proposed by Mr. Grote (Ann. Lyc. 1875, xi, 107)
for Mr. Morrison’s Agrotis montuna, and the genus is, in my opinion,
a good one, diflering from Agrotis in the narrow, reniform eyes, the
retracted head and anartijorm habitus. To this must come FacJmobia
alaske Grt., of which there is a specimen in the U. S. Museum,
easily recognizable by the discolorous claviform.
Among the species never recognized by Mr. Grote is Moeschler’s
Agrotis stanclingeri (Wien. Eut. Monatsch. vi, 132, pi. 1, fig. 4, May,
1862). To the courtesy of Mr. Moeschler I owed a chance to ex-
amine his type, and found it to be in all respects like Morrison s
species. The figure is accurate, and there is no doubt at all that
staudingeri must replace montana in the lists.
INIorrison described his species from Colorado, July 22d to August
12th, 12,000 feet. Afterward the species was received from Mt.
Washington, and Labrador is now added to the distribution. In
the collections made by Mr. Bruce there is a species which I at first
considered the same as that described by Morrison, but which offers
a number of constant points of difference, which I think justify a
new species fully congeneric with staudingeri.
Agrotipliila. colora*lo n. sp. — Ground color of head, thorax and prima-
ries an olivaceous luteous, or ocherous brown, the variation being quite consid-
erable. Front with a strong admixture of white hair, forming a white margin
to the eyes. Collar black centred with a whitish basal and terminal margin.
Patagife white margined. Abdomen blackish, wdth fine w-hite or pale yellow
hair. Basal line black, single, outwardly margined with white. A curved black
streak crossing the basal space on the internal vein, margined above with white,
and this with the white inner margin to the t. a. line makes a quadrate space at
base, the angles all extended. T. a. line incurved, the lower curve long and
reaching nearly to the middle of the inner margin. T. p. line with an even
outcurve, nearly parallel with outer margin ; inner line composed of connected,
black lunules, outer Hue a broad whitish shade. S. t. line white, ditluse, pre-

ceded by a series of more or less confluent sagittate l)lack spots, broadly inter-
ruiited sut)apically. A dusky line at base of fringes. .\ll the veins white marked ;
a mere trace of claviform. Orl)icular large, irregularly ov'al, black margined,
inwardly white ringed, centre pale. Eeniform large, kidney-shaped, narrowly
black ringed, inwardly white margined, centre pale. The space between these
ordinary spots is blackish, and there is a black spur from reniform to t. p. line.
Secondaries blackish fuscous to blackish, with white fringes. Beneath whitish,
both wings with narrow dusky margins and linear discal spots. Breast blackish,
legs with fine, thin, white hair. Antennte of male with whitish cilise. Expands
1.16 — 1.24 inches: 29—31 mm.
Hah. — Colorado, Bruce.
Both sexes of this species are before me from i\Ir. Bruce’s collec-
tions. There is considerable difference in the general appearance of
the sexes, though not in details of maculation. The male is the
smaller, and is sordid, more pale and less definitely marked ; in the
female the ground color is deeper, richer, and the white contrasts
very much more distinctly.
Comjiared with staudingeri, this species is larger, the claviform is
barely marked, and the orbicular is different in shape, large and
irregularly oval in this species, small and round in stemdingeri. The
species is in Mr. Neumoegen’s collection, and I have seen others from
Mr. Bruce. A good pair in the National Museum collection among
others.
.\grotipliila rigida n. sp. — Head, thorax and primaries dull fuscous
brown, with a yellowish admixture in the hasal and s. t. spaces. Front with
pale scales intermixed. Basal line evident, black, followed by a white shade.
T. a. line rigid, slightly oblique outwardly, white inwardly, margined outwardly
by black, which is a little extended on the veins. T. p. line outcurved over
cell, thence nearly parallel with outer margin ; inner line black, a little out-
wardly denticulate on the veins, followed by a rather diffuse whitish shade.
The veins are pale marked through the s. t. space, and aid in defining the series
of dusky, sagittate spots before the s. t. line. This latter is whitish yellow,
rather broad, distinct, very even, a little outwardly bent only on veins 3 and 4,
a blackish, interrupted terminal line. Claviform rather obscure, incompletely
outlined, concolorous. followed by a distinct yellowish shade, which extends to
the t. p. line. Orbicular small, oval, slightly oblique, black margined, pale
ringed, and wifli concolorous centre. Eeniform moderate, kidney-shaped, pale
ringed, with narrow black margin and concolorous centre. Secondaries smoky
fuscous, somewhat paler basally, with a dusky discal lunule. Beneath whitish,
powdery, with a common, broad, blackish, e.xtra median band : a discal spot on
all wings; primaries with a faint, dusky, submarginal band and secondaries,
with a dusky outer margin. Exi)ands 1 inch ; 2.5 mm.

This is one of the most interesting species I have studied, and will
not remain in the genus in which I have placed it despite its strong
habital resemblance to both standingeri and Colorado. The eyes,
while narrowed, are scarcely as constricted as in the type of the
genus, the fore tibiie are somewhat flattened and very heavily armed,
with longer sjiines at tip, and, finally, the front shows quite a long,
conic, corneous |)rojection, which is evident in neither of the other
species. It really agrees better with my genus Chorizagrotis, but
the form is not depressed, the eyes are narrowed, and the fi’ontal
jirotuberance is quite different. It has little or no habital resem-
blance with Chorizagrotis, and I think it best referi-ed for the j)resent
to the genus which in appearance it most resembles.

On the species of TRYPOX V1.01V inliabitiiig
America Xortli of Mexico.
BY WILLIAM J. FOX.
Through the kindness of Mr. E. T. Cresson, I have had the op-
portunity of working over this interesting genus of Fossorial Hy-
inenoptera. I do not offer any suggestion as to the proper position
of this genus, which has been placed in the Larridse by most Euro-
pean authors. Mr. Cresson has placed it in the Crabronidie, where
I prefer to leave it for the present at least. Herein eight new species
have been described, also two from Cuba and Mexico, res|)ectively,
have been added to our fauna. The species are, as a rule, easily
distinguished, presenting characters which are readily seen. The
types of all the species herein described as new, with the exception
of T. Johmotii (which is from my collection), and several of Pack-
ard’s, will be found in the collection of the American Entomological
Society.
The species are distinguished as follows :
Females.
Metanotum not trisulcate.
Abrloiiieii entirely black.
Metanotum punctured.
Wings blue-black; thorax clothed with black pile albilarse.
Wings with the anterior pair only fuscous, the posterior ones hyaline,
except apical margin; thorax witli pale pubescence.

Wings hyaline, their apical margin and the marginal cell fuscous; thorax
and abdomen with silvery pile excavafiini.
Metanotum with an enclosed space.
Anterior portion of clypeus without a carina; wings, except apical margin,
hyaline ; posterior tarsi, except base and ape.x, whitish. .olavaluill.
Anterior portion of clypeus with a strong polished carina ; wings fuscous;
posterior tarsi black project uiii.

These genera are separable liy the following characters. In Enclea
the second subcostal venule arises just beyond the end of the discal
cell, remote from the origin of the first subcostal, w'bile tbe first and
second median venules arise as far apart as the second and third ;
in Parasa the second subcostal venule arises just within the cell,
close to the first subcostal, and the first and second median venules
ari.se almost from a common point. Otherwise the venation is the
same. In the fore wings the s.-c. vein is remote from the costa and
the costal arises from its base; five s.-c. nervules, tbe origins of the
third and fifth approximately trisecting the vein beyond the cell;
discal cross-vein twice angulated, the independent vein arising from
its upper third ; a bifid false discal vein ; median four-branched ;
submedian present ; internal bifid at base. The hind wings have the
same venation in both genera.
Mr. E. L. Graef has very kindly loaned me his specimens of these
genera which comprise nearly all the species, and, from an examina-
tion of them, I have been enabled to complete this paper. The
species mav be separated in the following manner:

Euclea iiaiia n. sj). (Plate iv, fig. 15).
Primaries: costa sti’aiglit, ape.x subacute, outer margin convex, inner margin
nearly straight, then rounded to base. Dark glossy vval nut-brown, darker than
cippus (of the same color as some Florida examjiles of cippus), a very small round
black discal dot in the cell, not elongated as in cippus. Tw'o pea-green patches
of considerable size, both rouTided and edged outwardly and below with silvery
white and black. The larger patch occupies the space below the cell, not reach-
ing the base of the wing and narrowly sejtarated from the internal margin, rect-
angularly excavated op))Osite the outer third of the margin, the sinus partly
filled in with a patch of orange ferruginous scales that tends to be bisected on
the snbmedian vein. The patch extends beyond the end of the green patch,
reaqhing the obsolete subterminal line, which is lost in the ground color. The
other green patch is almost circular, in one example produced inwardly a little
above the discal dot. It is very narrowly separated from the fir.st jiatch and
almost reaches the costa. It represents the snbapical patch of cippus. Imt shows
no tendency to become divided. It is follow’ed by the usual orange ferniginons
patch, trisected by the uervnies and reaching the obsolete subterniinal line.
Fringes concolorous with primaries, interlined with paler at the base. Secondaries
scarcely paler than primaries, concolorous. Below, concolorous tvith secondaries
above, paler along internal margin of primaries and base of fringe The thorax
is dark like the fore wings, as in the basal tuft and tij) of abdomen. Expanse
of wings 18—20 mm.
Hab. — Florida. Ty[)es, two males, in the collection of Mr. Graef.
I cannot find that this sjiecies has been figured or described before.
1 have seen it in collections labeled querceti and qaercicola, but it
does not correspond at all with Herrich-Schtlfier’s figure of the.se
forms. It difiers from E. cippus var. moidtor in its smaller size,
round, minute, discal dot ; the green spots being rounded and not
triangular, the lower elliptical, less deeply excavated than in cippus,
the upper almost circular, not divided. The red patches are smaller
than in cippus, and are distinctly divided by the veins.
Euclea ferruginea Packard.
1864. — Pack. Proc. Ent. Soc. Phil. Hi, 338.
This species is fnarked like E. vur. delphinii, but has in addition
a ferruginous patch beyond the suhterminal band. It is closely allied
to E. cippus.
The following is Dr. Packard’s descriittion :
"% more reddish than the other species. . . . Basal green spot small, slightly
indented externally. Middle snbai)ical spot” [of the three snbapical green spots
which are very variable, often confluent] “large; lower one obsolete, with a few
scales connecting it with the reddish discal spot, which is margined above with
brown. Beyond the green spots the wing is suffused with rust-red. of a lighter
blue than any of the other species. Outer edge darker, like the costa. Beneath
both wings are alike, almost testaceous. Fringe brown.” Habitat, Canada.
Expanse 30 mm.
The larvii is unknown.

Thoi-MX and primaries dark hrown (burnt nmher), occasionally russet or dark
glossy walnut-hrown (the latter color is exemplified in a specimen from Florida
before me), with an elongated elliptical black spot of raised scales in the centre
of the discal cell. .\n oblique green hand, more or less interrujited, occupies the
basal third of the wing below the cell and runs narrowly around the cell, widen-
ing centrally and suhapically, but nowhere reaching the base or margin of the
wing. It is deeply excavated opposite the middle of the internal margin, the
sinus filled in with a large rust-red spot; another similarly colored, hut smaller
spot succeeds the suhapi' al portion of the band. Both these spots precede the
obscure, purplish, subterminal line. The green is narrowly bordered outwardly
and below with silvery white and narrowly surrounded by black. Abdomen
and secondaries colored like the thorax or paler. Below, concolorous with sec-

The green patches are larger than in the above, and the basal one
is bifid, sending out a narrow line of green above the rust-red spot.
Var. interjecta W. Var. (Plate iv, figs. 7, 8).
1 propose this name for the specimens connecting var. querceti with
var. monitor, in which a line of two or more little green dots connects
the outer part of the basal green patch with the subapical one. These
dots become larger and run together in specimens that are near
monitor.
* This is Clemens’ description: “ . — Body and fore wings rather dark red-
dish brown, with a small, nearly triangular pea-green patch, narrowly bordered
with dark brown, at the base of the wing beneath the median nervure, slightly
excavated behind, where it joins a bright brown i>atch. Toward the hind end
of the disc [cell], in its middle, is a minute, oval, dark brown streak ; two small,
pea-green, subapical spots, the one neare.st the costa minute.” It evidently re-
fers to the var. deJphinii. Clemens also describes the genus and the larva of his
species, hut the characters are all borne ont by specimens of Euclea cippus.

In tins the green foi’ins a complete band, e.Ycavated aliove the
middle of the internal margin. Harris gives a good figure of it in
“ Insects Injurious to Vegetation,” page 420.
The above varieties are all connected by intergrading forms.
The larva is elongate, rounded, the dorsal i-egion Hat, nearly level,
of uniform width, rounded at the extremities; sides nearly jierpen-
dicular. Head whitish, labrum and sutures of clypeus yellowish ;
ocelli black ; jaws dark brown ; retracted beneath joint 2. Along
the subdorsal ridge of the body on each side is a row of elongated
spinose tubercles, on joints 3 to 18 inclusive; those on joints 3, 4,
5, 1 1, 12 and 13, about three times as long as the others. The spines
are short, black, and arise from conical bases. Another lateral row
of spinous tubercles beginning on joint 3, those on joints G to 12
situated above the spiracles (none on joint 5) the one on joint 4
about as long as the subdorsal one, the others of uniform length,
longer and rather slenderer than the short subdoi-sal ones. A ro'w
of dorsal and lateral elliptical dej)re.ssions, each containing two ir-
regular wdiitish dots, only appearing distinctly when the body is
retracted. The body is covered wdth very minute transparent granu-
lations. Spiracles very small, circular, projecting, yellowish.
The larva varies much in color, from sordid ])urplish to green;
there is a subdorsal band covering the row of tubercles which varies
from ferruginous through yellow to gi’een (it may be concolorous
with the body) sometimes narrowly and irregularly edged with black
or crimson, but always thrice interrupted by a subquadrate spot of
red or dark brown, viz., between joints 6 and 7, 9 and 10, 11 and 12.

Closely allied to E. pcenulata, from which it differs only in the
jtresence of the discal dot and the somewdiat smaller size of the green
patch which does not reach quite .so near to the costa, nor exactly to
* This variety comes nearest to Cramer’s figure of cippns. I have had some
doubt about referring the species to at all, as I have never seen a specimen
that exactly corresponds to Cramer’s figui-e in which the greeTi band is broken
into three triangular spots: but this may occur. The figure is too poor to base
critical remarks upon, but it seems extremely ju’obable that it is the present
species that was intended. However, if this should not prove satisfactory, there
are plenty of other names, as may be seen from the above .synonymy. There is
no doubt about the figure of delphinii.

the suhterminal line. The mirrow space between the obscure sub-
terminal line and the green patch is filled in with a rust-red shade.
The larva, as described by Mr. Pearsall, does not seem to differ
from Prof French’s description of E. pceaulatn more than is the case
in many examples oi' clppus, and I expect that a good series of moths
will show that we have to do with but one species. I have been
able to examine but one specimen of pcenulata and four of elUotii,
among the latter the type of the species by the kindness of Mr.
Pearsall.

1860. —Clemens, Proc. Acad. Nat. Sci. Phil. 159.
1881. — French, Papilio i, 144.
Thorax and primaries dark brown, the green patch on the wings similar to
that of cippns in its exterior and interior outline, but extending outwardly to
the subterminal line and much fui'ther basally over the cell, reaching the base
of the wing, but not extending on to the costa. It is edged with silvery white
outwardly and below, and narrowly with black, and the sinus above the middle
of the interior margin contains a large rust-red spot as in cippns. The brown
space along the costa widens toward the base. Secondaries paler brown ; under-
side still paler, concolorons. Expanse 28 mm.
Hub. — Illinois.
Prof. French describes the larva, which is very similar to that of
cippm, but lacks the subquadrate spots, which internutt the subdorsal
bands of that species.

Primaries wood-brown, nearly covered by a large green patch more extensive
than in psennlntn Clem., slightly waved opposite the cell, and rectangularly exca-
vated opposite the outer third of the internal margin, much more distinctly in
the male than in the female. The patch is edged outwardly and below with a
darker line, and is but very narrowly separated from the costa and internal
margin, more broadly just at the base of the costa. Secondaries pale testaceous,
unicolorous. Below concolorons with secondaries above. The thorax is dark
brown, the abdomen pale. Expanse % 26 mm. ; 9 nim.
Hub. — Texas.
Mr. Grote carefully separates this species from Euclea poemdata
Clem.
I know of no description of the larva. The species seems, in some
resitects, intermediate between the genera Euclea and Parasa, and it
will be very piteresting to observe the affinities of the larva when
found, as the larva} of these genera difier decidedly.

Primaries wood-hrown, the pea-green patch smaller than in incisa Harv. It
is separated by a brown line from the costa and reaches the internal margin, but
is not excavated, being only slightly waved above the internal margin. It
reaches the base of the wing only along the margin, being replaced by a trian-
gular patch of the ground color which rests upon the costa. The green is bor-
dered with a narrow brown line, and the veins in the terminal space are marked
with brown. A blackish brown shade along the center of the outer margin.

Very similar to P. viridus Reak., but the green baud is still narrower. Prima-
ries wood brown, crossed by an oblique pea -green baud that is separated by a
brown line from the costa, and is continued along the internal margin to the
base of the wing. The band is edged with brown, but there is no blackish
shading in the terminal space, though the veins are marked with brown. Sec-
ondaries pale yellowish at base the outer half wood-brown. Below, yellowish
testaceous ; costa, outer third of primaries and fringes, brown. Thorax pea-
green ; abdomen largely tinged with brown. Expanse about 20 mm.
Hub. — Middle States.
The larva is somewhat ovate in outline as seen from above, the
last segment being produced into a little pointed tail. The dorsal
region is flat, highest at joint 5, and diminishes to the extremities.
The subdorsal ridges bear each a row of large round warts covered
with spines, those on joints 3, 4, 5, 11 and 12 the largest, the rest
much smaller; a similar row above the spiracles, all small. The
head is retracted within joint 2, and this in turn under joint 3.
There is a double row of blackish impressed spots in the dorsal
region and elliptical depressions on the sides, but the skin is nearly
uniform, soft and smooth. Color greenish brown, lighter, more red-
dish posteriorly, shaded on the dorsum with dark orange ; a number
of indistinct, brighter waved lines. Below colorless, bordered by a
salmon colored band.
® Mr. Henry Edwards has called my attention to a fact which I have recently
verified, viz., that Herrich-Schafler’s figure of chloris represents the species known
as Parasa fraterna Grote. Hence the synonymy will have to be altered as above.

Closely related to Euclea is the genus Adoneta Clem., but in our
lists it has not been associated with its allies. It differs from Euclea
in the shorter pectinations of the autenme of the male and the more
slender body. The shape of the wings and pattern of maculation
are the same, but the venation diffei’s in that Adoneta has but four
subcostal venules, while Euclea has five in the fore wings, and the
subcostal vein in the hind wings divides nearer the tip of the wing
in Adoneta. These are all weak characters.
The larvse are of the same structural type in both genera, but
that of Adoneta is more highly colored.
From a consideration of characters, drawn principally from the
larva, I would arrange the genera of the Cochlidiie somewhat as
follows, omitting the genera of which I do not know the larva ;
L. flexuosa and L. coesonia of Grote, do not belong to Lhnacodes,
and will probably have to be referred to Heterogenea or an allied
genus, as, indeed, Mr. Grote has himself suggested.*
Varina ornata Neum., in my opinion, does not belong to the Coch-
lidiie.f I have examined a 9 specimen which Mr. Graef has kindly
loaned me, and a % from Prof Smith. If the moth is a bombycid
at all, it will have to be referred to the Dasychirie as its characters
exclude it from the other subfamilies. I wmuld add the following
characters to Mr. Neumoegen’s description of the genus :
Primaries 12-veiued ; internal vein not furcate at base; median 4-branclied,
vein 5 nearer to 4 than 4 to 3 at base ; cell open ; 6 arising from cross-vein near
the subcostal; a small, narrow accessory cell; 7 from 8 immediately beyond
accessory cell ; 8 and 10 together from end of accessory cell ; 9 from 8. rather
more than half as long as 8. In the secondaries 3 and 4 arise together from the
end of the median ; cell open ; 5 absent, represented by a fold ; 7 from 6 beyond
the end of cell ; 8 touches the subcostal at about one-sixth the length of cell from
base
Tongue present, but weak ; ocelli small. The thorax is covered
with scales and hair, and not hair alone, as Mr. Neumoegen states.
A knowledge of the larva of V- ornata is much to be desired.
* New Check List, page 63. I think that csesonia may prove to be synonymous
with Heterogenea shurtleffii Pack. Flexuosa is congeneric, and may be only a
form of csesonia.

line extends from the middle of internal margin to median vein, l>ut does not
cross the vein nor extend on to the fringe as does the corresponding mark in

between this mark and the base of the wing is of a ferruginous brown, paler
than the rest of the wing and narrowly separated from the white mark by the
ground color. Expanse 22 mm.

Genus 1*AC'KARI>I.4 G. and R.
This genus was characterized by Dr. Packard, in 1864, f as Cyrtosiu,
but this name, being preoccupied, was sub.sequently changed by
Grote and Robinson.
The species are subject to considerable variation, and are usually
rare. I have examined the male genitalia of three species and I
cannot find that they offer any characters to afibrd specific separa-
tion. The supra-anal plate in all narrows ra]fidly, and is extended
backward in a long, evTii, narrow prolongation that slopes downward
without curving, being pilose beneath. It resembles the same part
in Datana, but is much less strongly bent down. The side pieces
are simple, concave inwardly, slightly tapering, the ends rounded.
The larvie are small green Limacodes, much resembling Parasa fra-
terna in general shape, but lacking the spinose subdorsal tubercles,
'fhe end of the body is ])roduced into a little “ tail” as in Parasa,
which is often marked with red above, and this constitutes the only
colored marking. They feed on the leaves of any deciduous tree,
usually frequenting the central or more shaded parts of the woods.
Only one brood occurs each year in New York, the larv’je maturing
in September.
Dr. Packard has kindly allowed me to see his material in this
genus, and I believe the following arrangement of species corresponds
with his opinion.

Primaries whitish bull’, consisting of a dull white ground “dusted with ocher-

as in elegans, but much more obscure, in some examples hardly discernible. The
white bands are scarcely paler than the ground color being defined by theocher-
ous scales; the outer dark shade of the inner band and the round superposed

Primaries chalky white, irrorate with chocolate-brown scales and thickly
duste<l with ocherous brown scales at the base of the wing and internal angle.
Two parallel, oblique, cbocolate-brown bands, the inner somewhat undulate,
reaching from the basal third of the inner margin to near the center of costa,
the outer from the basal two-thirds of inner margin till it joins a third curved
baud, which extends from the costa just beyond the end of the first band to
just above the internal angle, where are three superposed, rounded, triangular
white spots, the lower one very small, all narrowly surrounded by chocolate-
brown. In the single example before me the space between the first two bauds
is strongly filled in with chocolate-brown, especially on the costal half of the
wing, and this shade spreads outward diti'usely beyond the third band in the
center of the wing. Secondaries even paler than the primaries, dusted with
brown scales. All the fringes are narrowly lined at base and near tip with
chocolate-brown. Expanse of wings 26 mm.
Larva.— Vi\\Q, or whitish green with four longitudinal slight ele-
vations or ridges, viz. : one suhdorsal and one su[)ra-stigmatal on

The ground color of the primaries is the same as in geminata, the lines and
superposed white spots are the same (though in one example there is a trace of a
fourth white spot), but the ocherous brown or sable brown and chocolate-brown
shadings are more extensive, w'hile the secondaries are pulverulent dark blackish
brown. A male example befoi’e me (fig. 25) has the basal space filled in with
sable brown, the rest of the wing chocolate-brown, obscuring the lines, except a
subquadrate apical space, where the white ground color prevails, irrorate with
brown scales. Fringe paler at base. The female (fig. 24) has a basal ocherous
brown shading, but the chocolate-brown shade is confined to the space enclosed
by the second and third bands at the internal angle, leaving the ground color to
appear on the rest of the wing. Fringe ocherous. Expanse 23 — 27 mm.
Mr. Grote’s ocellata was apparently founded on examples similar
to the female I have described above.

any differences.

It seems probable that this species is only a very dark variety of
P. albipunctata, but I have not seen enough specimens to be able to
decide. Mr. Grote’s description is substantially as follows, and well
characterizes this form :
“Entirely blackish, with a faint brown shading about internal angle, where
are two white, unequal spots. Fritige blackish, concolorous. interlined with pale
and with a distinct white fleck below apices. The usual lines on the primaries
are lost in the ground color; the outer may be made out, followed by a whitish
shade on costa. The costal edge at apices is whitish. Secondaries concolorous,
blackish, paler beneath ; the fringe is paler outwardly. Expanse 20 — 22 mm.”

REVISIO]^ OF THE DOXACT.E OF BOREAE AMERIC A.
BY CHARLES W. LENG, B. S.
Donacia was established by Fabricius, in 1775, for a European
species allied to our mbtilis, and the name, derived from the Greek
donax — a reed, — is indicative of the habits of that and the other
species comprised ; all are subaquatic, the larvie feeding in, the im-
agines being found about reeds, pond lilies, Sagittaria and other
water plants. The earliest descriptions of our species are by foreign
authors, Ahrens and Kunze, in 1810 and 1818 respectively. Thomas
Say described five in 1823 and 1827, Newman added others, and
Kirby still more. In 18-15 there was published a “ Monographie”
by Lacordaire, which swelled the number considerably. In 1851,
Dr. LeConte reviewed the described species, noting many synonyms,
and in 1873 Crotch made a Synopsis, on which the names now in use
are based. In all, about 70 names have been proposed, and over
100 pages printed in descriptions.
Some confusion still existing, I have attempted in the following
pages to give the characters by which the really distinct species may
be recognized. Unassisted, this would have been both presumptuous
and impossible; but in advice and material I have received so much
help, that I hope the result may be found satisfactory. To Dr. Geo.
H. Horn I owe the free use of a collection representing all the de-
scribed species, each one specially compared with the types of Dr.
LeConte’s s[>ecies in the Cambridge Museum ; as well as the results
of his observations on the genus for many years back. Through
the favor of Prof. C. V. Riley, I have been entrusted with the col-
lection of the National Museum. To Mr. Frederick Blanchard I
owe many valuable suggestions and sets of the species living on the
Concord River. To Messrs. Roberts, Liebeck, Westcott, Wickham,
Hulbert and Sherman, my thanks are due for specimens. Finally,
my friends on Staten Island, William T. Davis and J. C. Thompson,
have freely given me the use of their collections and time.
Before using the synopsis, the reader should observe the following
explanation of the terms employed.
“ Elytra truncate at tip, or subtruncate.” Under this head are
included all the forms that are in the least truncate, or even doubt-
160
CHARLES W. LENG.
fully SO, and the only form excluded is that in which the tip is evi-
dently rounded. In such the sutural margin is sinuate.
“ Mesosternum narrower than the coxa.” By this is meant that
the portion of the under surface seen between the middle coxjb is
narrower than those coxre separately. It is used as a convenient
measure of the width of the insect, being narrowest in the conspicu-
ously slender species, and may be inferred where it is difficult to see,
as when the insect is pasted on a point.
“ Sutural margin sinuate posteriorly.” In many Donacite the
elytra are declivous at the apex ; the elytra are closely joined at the
suture in repose, but the margins on the declivous portion appear
double, and although they truly meet, there is a second apparent mar-
gin within the true one. This second margin, starting not more than
one-fourth the length from the tip — often less — is sinuate, or curved
more or less, away from the suture. Thus a space somewhat ellip-
tical in shape is formed, sometimes depressed, sometimes in the same
plane with the rest of the elytron, and always destitute of punctua-
tion. This sinuation might also be described as a sinuate displace-
ment of the sutural stria.
“ Posterior femora elliptical.” In all Donacise but ru/a, the j)os-
terior femora are decidedly pedunculate. In that species the neck
is not evident, and I have followed Dr. LeConte’s use of the term
elliptical to describe them, though they are actually much broader
at the apex.
Certain characters are subject to great individual variation. These
are the color, the relative length of the antennal joints, the number
and size of the femoral teeth or spines, and the punctuation and
sculpture of the upper surface. While diherences in these respects
are, to an extent, indicative of specific rank, it is important that
they be not carried too far, and I have endeavored to mark their
limits in the descriptions which follow the synopsis.
The dilation or extension into spinous ])rocesses of the tibiae is
very evident in some species. In pis^eatrix and jKilmata this is esj)e-
cially true of the middle tibiae, ami a spinule may also be seen beneath
the dilation. In certain of the convex species the dilation is more
apparent on the front tibiae. The character, however, varies greatly
in individuals of the same species, and I have not made use of it in
the synojLsis.
The sexes in most Donaciae are widely differentiated. As a rule
the females are broader, the posterior femora are either without or

with fewer and weaker spines than the male, and the last dorsal
segment is rounded at ajiex and more or less elongate. The males
besides being narrower and more strongly armed on the femora, have
the pygidium shorter and either truncate, arcuately emarginate, or
acutely triangularly emarginate, but never rounded. The males of
palmata have the anterior tarsi dilated, and the same sex of piscatrix
has the first ventral segment excavated.
All the species of Donacia are subaquatic in habit, frequenting
either the pond lilies, on the broad leaves of which they may be seen
from A{)ril to Septendier, or the rushes and sedges that grow in danqi
places.
In the following synoptic table several new names will be noted ;
these are :
cmcticornis Newn., which was formerly called lucida Lac., or in
the check lists rugifrons Newn.
pusilla Say, which antedates and replaces cuprea Ky.
rufa Say, which antedates and replaces Kirbyi Lac.
The scheme proposed is as follows :
Head and thorax evidently pubescent above Group A.
Head occasionally, thorax never pubescent.
Elytra truncate at tip, or subtruncate.
Form decidedly flattened ; mesosternum about as broad as each coxa.
Group B.
Form more convex; mesosternum narrower than the coxa Group C.
Elytra rounded at tip, the sutural marsin sinuate posteriorly; form convex;
mesosternum narrow Group D.
Group A.
Three species fall into this group which are not otherwise at all
similar. It will be noted puhes^cens is the only species with pu-
bescent elytra, and puhicollis the only one with the femora destitute
of teeth or spines in both sexes. A badly rubbed specimen of hir-
ticollis might be placed in the next group, from all the species of
which it may be distinguished by the very small tooth of the femora,
which is often reduced to a mere lump. The species are separated
thus :
Elytra without pubescence; posterior femora with a small tooth. ..liirticolli;S.
Elytra without pubescence; posterior femora simple ptibicollis.
Elytra evidently pubescent; posterior femora toothed |>iibesceii$$.

Group B.
The s]iecies comprised in this grou]) are similar in appearance, all
being evidently flattened above ; the first ventral segment is not only
flattened, but longer than all the others combined ; the color is
frequently testaceous ; the middle tibite are expanded at tip and are
armed beneath with a spinule ; the mesosternum is conspicuously
broad in all excej)t piscatrix male. These are the species which
frequent the pond lilies, and Mr. Blanchard has suggested that their
great breadth of beam indicates an adaptation to their particularly
aquatic existence, in which connection it is worthy of note that the
])ubescence of the under surface, characteristic of the tribe, is in
them especially develojied. The species are :
Thorax narrowed in front; posterior femora plnridentate male, simple female.
floridte.
Thorax quadrate, or wider in front; posterior femora dentate in both sexes, the
male often hi- or tridentate.
Auteunffi with second and third joints nearly equal ciiicticoriiis.
Auteuuffi with third joint much longer than second.
Elytra truncate.
Anterior tarsi of male dilated palinata.
.Anterior tarsi simple liypoleiica.
Elytra subtruucate, form more convex; first ventral segment of % exca-
vated piscatri.x.
The specimens which I include under the name cincUcornis may
be divided into three species or varieties or races as follows:
Prothorax not coarsely punctate.
Posterior femora male very large and strongly dentate, posterior tibiae curved
and serrate lucida.
Posterior femora less developed unnamed.
Prothorax punctate at base and apex only; posterior femora less developed.
tibiae straight, or nearly so proxima.
Prothorax coarsely punctate over its entire surface ; femora and tibiai as in pre-
ceding magnifica.
From the number of specimens before me, showing all gradations
in the thoracic sculpture and femoral armature, I do not think these
forms can be recognized as species, and I suggest that they be placed
in our lists as varieties.
Group C.
'fhis group includes subtilis, of which the female might, with equal
propriety, be placed in the preceding group, though the male is de-
cidedly more convex ; and several species which, by their convex
form, are associated with the last group, l)ut differ in the truncate

elytral tip. Two species, Harrisu and distincta, present also the
peculiar sinuation of the sutural margin of the elytra which charac-
terizes that group. This consists in the displacement of the margin
for a space equal to one-fourth the length of the elytron, whereby,
wdien the elytra are closed in i-epose, an elliptical space is formed
hounded by the displaced margins. In Harrisii the margin appears
double, and the inner sinuate portion is in a higher plane than the
outer straight portion. In most of the species the material which
fills the sinuation is in the same plane.
Eyes of normal size; sutural margin of elytra straight, except in distincta.
Thorax punctate, not or scarcely tuberculate.
Thoracic punctures coarse, uniform siiblilis.
Thoracic punctures uneven, finer punctures mixed through the coarser.
poroi^ioollis.
Thorax uneven on the disc, tuberculate on the sides.
Sutural margin of elytra straight.
Elytra with two transverse indentations cPqiialis.
Elytra not indented ; posterior femora male dentate, female simple.
t II bore II lata.
Sutural margin of elytra sinuate distincta.
Eyes small; thorax tuberculate; sutural margin of elytra sinuate.... Harrisii.
Of these species, porosicolUs seems rare ; the specimens I have are
far more slender than any other, and there is an appearance of an
abrupt demarkation on the sides of the elytra. Inasmuch as siibtilis,
its nearest ally, is constant in the style of its punctuation, I have
preferred to use that character for the separation of the two species.
1'he specimens under subiilis may be separated thus :
Thorax straight on the sides; second and third antennal joints subequal.
Thorax constricted at middle ; third joint of antennse longer than second,..r!tgos«.
but on account of the variations observed in these characters in other
species, I doubt rugosa being a distinct species ; torosa Lee. is included
with distincta.
Group D.
The species here included are readily distinguished by the convex
form, rounded elytra and sinuate sutural margin. They may be
se])arated as follows :
Thorax depre.ssed without basal and medial groove.
Posterior femora dentate in both sexes piisilla.
Posterior femora dentate in male only Icinoralis.
Thorax convex, punctured, and with an evident basal and more or less evident
medial groove.
164
CHARLES W. LENG.
Posterior femora pednncnlate ; thorax closely punctulate.
Legs (lark ; posterior femora deiitate in both sexes eiimi’siiiata.
Legs (lark ; posterior femora dentate in male only iiiof allica.
Legs rufo-testaceous ; posterior femora dentate in both sexes flavipoN.
Posterior femora elliptical ; dentate in both sexes; thorax sparsely punctured ;
legs rufo-testaceous riifa.
Tlie species contained in this group may be arranged in jtairs as
placed above ; the differences, however, between pudlla and /(?Hior«^hs,
emcirginata and metallica, jiavi2)es and rufa, are feeble. The first
pair are readily isolated by the depressed thorax, the second by the
dark legs, the third by the yellow legs and more convex thorax. It
must be observed that the femoral tooth is less developed in the
females throughout the genus, and is particularly weak in this group ;
femora are subject to some variation in form and the punctuation is
inconstant in many of the preceding species, so that, while the con-
siderable number of specimens before me are separable by the char-
acters given, the reader must be prepared to find some which, in
these respects, will vary from the tyj)ical form.

In the following pages I propose to copy either the original de-
scription, or that of Dr. LeConte’s paper, su})plementing each with

“Antenme elongate, the basal joint pale, the apical black: vertex shining;
prothorax quadrate, most minutely punctured, with an impressed dorsal line;
head and prothorax black seneous, elytra testaceous, shining; elytral apex trun-
cate; metafemora elongate, incrassate, bidentate; legs testaceous, femora with
two black vittae. [Corp. long. .325 nnc., lat. .1 unc.]
This species has been long known as lucida Lac. The synonymy
was pointed out by Dr. Horn some time ago, [lint. Am. I, p. 9] but
has not been corrected in the Check List. Lacordaire’s descri[)tion
of lucida is as follows ;
“Moderately elongate, above metallic green, very shining, elytra rufe.scent;
beneath densely cinereo-sericeous ; antennte and legs rufous, maculate with
black ; protborax transverse, slightly narrowed behind, the angles obtuse but
distinct, the margin in front and at the middle of the base, reflexed ; towards
tbe front on each side obsoletely tuberculate; above vaguely rugose, with a
dorsal sulcus abbreviated behind and an impressed puncture; elytra flattened
on the disc, declivous at apex, which is squarely truncate; bi-impressed, punctato-
striate, interstices flat, vaguely transversely rugose. Length 3j — 4i lines;
width li — Ij lines.”
Mesosternum as broad as the coxa; first ventral segment longer than the meta-
sternum; third joint of antennse about equal to the second; posterior femora
incrassate and dentate.
Male. — Pygidium truncate; posterior femora strongly incrassate and sharply
dentate, or even tridentate.
Female. — Pygidium elongate and rounded at apex; posterior femora feebly
incras.sate and unidentate.
The posterior tibiae are serrate in well developed specimens % .

to an entirely ditierent insect belonging to the last group. The va-
riations observed are in size, as indicated above ; in color, which may
be a uniform greenish black, or a much lighter color almost testace-
ous, or a combination of both ; in the femoral teeth, which depend
in number and size upon the development of the insect, and may be
traced through gradually weakening forms, from three prominent
spines in the male to a single obtuse tooth in the female ; and in the
relative length of the antennal joints, the third being usually as
short as the second, but sometimes evidently longer. It is never
twTce as long, however, as in the following species. Although se-
lected specimens can be made to look very different, I can find no
character in these variations to base even a variety.
With the punctuation of the thorax, it is somewhat different. In-
termediate specimens do occur, and indicate the close relation be-
tw’een cincticornis and its varieties proxima and magnijica, but the
greater number are readily separated, as indicated in the synopsis.
Food-plant is undoubtedly the pond lily, Nuphar advena. I have
always found the insect on this plant, frequently within its yellow
flowers, and Mr. Roberts has also in Vermont, and Mr. Blanchard
in Massachusetts. Furthermore, it does not occur in localities where
there are no lily ponds. The white water lily, Nymphcea odorata,
occurs in many ])onds with the Nuphar, and the insects show no
partiality for it in the imago stage. The original descriptions of the
varieties are :
Var. proxiina Kirby. — “Thighs bidentate, witli one tooth minute; above
dark violet glossy, head rather bronzed ; punctures of the elytra green gilt; body
underneath covered with a satin silver pile. Length 5 lines. Taken in Canada
by Dr. Bigsby. Body a little flattened, covered uuderneatb with a dense coat
of glittering silver pile resembling satin. Head a little bronzed, channeled
between the eyes, minutely punctured, palpi testaceous ; antennae entirely black ;
prothorax in the disc dark violet and channeled, sides bronzed and impressed,
anterior tubercles not prominent; scutellum bronzed ; elytra nearly black, with
a slight tint of violet, punctures green gilt, interstices of the rows not wrinkled,
an anterior impression near the suture, rounded at the apex; posterior legs long,
with the thighs somewhat curved, attenuated at the base, curved at the apex,
with two teeth placed consecutively, the first long, slender and acute; the last
wide, short and denticulated posteriorly. This species is nearly related to cras-
sipes Fab., but the antenuse and legs are entirely black, and the teeth on the
posterior thighs are not equal.”

Var. rufescens Lacordaire, is smaller, and has the antennal joints
very moderately thickened externally. It occurs near Lowell,

my specimens as well as for pointing out its differentiation. It is
also found in New York by Mr. Sherman, and in New Jersey by
Mr. Liebeck, and is possibly mixed in collections with cincticornis,
from which it may be separated by the length of the third antennal
joint.

D. piseatri.v Lacordaire Original description translated.
“Pale rufous, opaque; chest and head blackish; beneath cinereo-sericeous.
Prothorax subtransverse, somewhat narrowed at base, anterior angles obsolete,
the posterior distinct; bituberculate on each side, smooth above, impressed at
base; the dorsal channel narrow, subobsolete. Elytra subparallel, apex declivous,
broadly squarely truncate; disc flat, vaguely bi-impressed. punctato-striate ; tbe
interstices slightly convex, subporcated, on all sides very slightly coriaceous.
Length 44 lines; width lines.”
Mesostenmm as broad as the coxa female, narrow'er male ; first ventral segment
about as long as the raeta.sternum ; elytral tip subtruncate, not so squarely ter-
minated as in the preceding; form more convex, making an approach to the
convex forms of following groui)s ; antennse comparatively shorter and slightly
stouter; femora dentate, middle tibiae unsymmetrically dilated at tip.
Male, pygidium subtruncate; posterior femora strongly dentate or bidentate;
first ventral segment excavated at middle, i.e., there is a depressed pit, such as
the point of a dull pencil might have formed.
Female, pygidium elongate, rounded at tip; posterior femora unidentate, first
ventral not excavated.
Varies in color from the typical “ pale rufous” to a dark bronze
just as the preceding species do; alutacea Lee. is the name ap{)lied
to the darker forms in many collections, but it is impossible to draw
any line between them. The intermediate forms are among the most
beautiful specimens in the genus, the suture being broadly bronzed
and the other part of the elytra golden testaceous.
This species occurs with the preceding on the leaves and in the
dowers of Nuphar, and I have taken it on the roots of that plant,
where it pupates, enclosed in an oval cocoon of leathery consistency.
It is mixed in most collections with palmata, and the females are not
readily separated.

This species is very abuiulunt on Staten Island at a jtond Itordered
l)y marshy ground, where grow a nninber of sedges and grasses, on
whicli the insects principally occur. They wander to the lilv pads,
but do not occur in ponds where the lilies alone are abundant. I
therefore conclude that they live on these sedges. Mr. Clarence M.
Weed has noted their abundance in a similar situation in Ohio ( Bull.
Ohio Ex. Station, 1889).
Var. rugosa Lee. — Differs only as stated in the synopsis. The

Dr. John Hamilton has advised me of the following facts regard-
ing the habits of this species : “ I have taken (equaUs in April in a
swampy meadow just thawing out. The insects were in the bunches
of sedge and coarse grass, and must have been imbeded in ice most
of the Winter, or under water much of the time. I take the same
species in this swamp in July on the sedge, and with it I once took
a few specimens of mbtilis. This meadow is bottom ground between
two hills.”

prothorax subquadrate, narrowed at the base, anterior angles prominent, the sides
strongly tuberculate anteriorly, the disc very convex, slightly closely rugose,
with a deep dorsal channel, entire; elytra short, oblong, the apices declivous,

Male, pygidium truncate, emarginate at middle; posterior femora with an
acute tooth. Female, pygidium elongate, rounded at tip, posterior femora usually
unarmed, at most a feeble rudimentary tooth.
This species is usually quite rufous, tinged with metallic lustre,
but varies to a darker color, nearly as cupreous as mbtilis. It was
found at Jamesburg, N. J., July 4, 1890, in large numbers on the
Sagittaria in the cranberry bogs not mixed with any other species.
It does not occur in this vicinity on the lilies or reeds, and I have
no doubt the Sagittaria is its food-plant.

The sutural margin of the elytra is slightly sinuate in this species
for a short distance, not exceeding one-tenth the length, near the
apex. It seems to be rare, and 1 cannot separate it with the si)eci-
mens before me from torosa Lee. It would be hazardous, however,
to unite them without a larger series for coni[)arison.

prothorax rather wider than long, very minutely, thickly and confluently punc-
tured and wrinkled, channeled with a pair of impressions on each side, anterior
tubercles not prominent, scutellum downy; elytra very glossy, punctured in
rows, a single anterior impression near the suture, truncated at the apex ; three
intermediate segments of the abdomen have a yellow margin; legs obscurely
rufous, thighs bronzed in the middle, posterior thighs with a minute tooth near
the apex.”
Mesosternum narrower than the coxa; first ventral shovtGr than the metaster-
num; elytral tip rounded, not truncate, as described above. It is very little
rounded, but compared with subtilis it is seen to be distinctly rounded. Sutural
margin sinuate near the apex, the sinuation filled with a glittering impunctate
plate; form convex, thorax depressed, third and second joints of antennae sub-
equal.
3Iale. pygidium truncate and slightly arcuately emarginate.
Female, pygidium more elongate, rounded ; tooth of posterior femora smaller.
The sexes of cuprea are not readily distinguished.
The color varies from briglit reddish or cupreous, through many
shades of metallic color, to a form nearly black. The legs are yel-
low or rufous in the majority of specimens ; in a few they are nearly
black, and constitute the variety pyritosa Lee.
The relative length of the antennal joints is not constant, and
will not serve to separate pyritosa, as a species, as stated by Mr.
Crotch. From some variation observed in the specimens before me,
I am doubtful if it is a sufficiently defined variety even to be con-
tinued in the list.
The indentations of the elytra are somewhat variable in depth
and consequent distinctness, but are never very marked. The species
is sometimes mixed in collections with CBqualis Say, and the depth
of these indentations afford a convenient index for their separation.

Synonymy and Bibliography.
The greater part of the following synonymy is derived from the
“ Catalogus” of Gemminger and Harold, from Dr. LeConte’s Syn-
oj)sis, or from Mr. Crotch’s paper. Of the remainder a part is due
to comparisons made by Dr. Horn with the LeConte types at Cam-
bridge, and the balance is the result of a comparison of the published
descriptions. All the older names have been recognized, and in
some instances those which have been in use have had to give way
to them.

Kovi!«ion of the g;eiiera and species of AISTHOXOMIRJI
iiiliabitiiig North America.
BY WILLIAM G. DIETZ, M. D.
iSince the publication of “ The Rhynchophora,” (Proc. Anier.
Philos. Soc. 1876) but few new species belonging to the tribe under
consideration have been described, while the amount of material ac-
cumulated in our collections has been considerable. It was my in-
tention, originally, to confine the following essay to Anthonomus
proper ; the discovery, however, of new and im})ortant characters,
as well as a greater appreciation of others heretofore deemed of but
secondary importance in the classification of genera of this tribe,
has led me, step by step, to include all the genera and species oc-
curring within our faunal limits. The Anthonomini of Europe
have been made the subject of a monogra})h by Desbrochers des
Loges (Monographic des Balaninidse et Anthonomidie d’Europe et
de confines Mediterranees, 1867), which has, however, scarcely offered
a suggestion that might have aided me in the study of our North
American species. The genus Orchestes was similarly treated by
Brisout (Monogr. Ann. Fr. 1865). Very recently a paper has been
published on the species of Anthonomus inhabiting Great Britain ;
the latter publication I have not seen.
In taking a general comparative survey of the present tribe of
Curculionidie, as presented by our own with that of the European
fauna, one is struck with the few points of close similarity encoun-
tered. Referring to Anthonomus proper, the European species, as
far as I am able to judge by the not inconsiderable number repre-
sented in my collection, present far greater uniformity, structurally
as well as in general habitus, than our own. In all of them the
funicle of the antennie consists of seven joints, and species entirely
clothed with scales do not occur. The European genus Bradybatus
Germ., in which the claws are connate at base, is not represented in
our fauna.
In defining the limits of the tribe, a modification of LeConte’s
arrangement becomes necessary. Several new genera have been
included, whose position is somewhat doubtful, and which, with equal
j)ropriety, might have been placed in some other tribes of the Me-

AVILLIAM G. DIETZ, M. D.
corrhyndiid series. One of these, Alycodes, whose affinity to the
Erirrliini is well shown by the formation of tlie ventral segments,
the covered pygidiiim and the sim])le claws, and by its toothed
femora, would have to he placed after Dorytomus, hut the obliquelv
truncated anterior thoracic opening, the prosternum short in front
of tlie coxffi, the antennal formation, etc., have induced me to jilace
it in the })resent tribe. Another aberrant genus, Euclyptus, resem-
l)les Xoto/ovius basu/is Lee. in its general appearance, and also in the
ventral formation ; the prosternum, however, is short in front of the
coxffi, the j)ygidium freely exposed, and the appendiculate claws
warrant its position here. Elleschus, placed by Lacordaire among
the Tychiides, I have retained in the present tribe; the second, third
and fourth ventral sutures are slightly bent backward at the sides;
this character is also noticed in a few Anthonomi (A. elegam, jinii-
perinu-s). Simple claws occur in a small number of species, dis-
tributed among several genera. This abnormality in the present
tribe is the final result of a gradual reduction in development, passing
from the bifid claws of some Anthonomi (Anthonomorphus) to the
very small, though distinct tooth of Chelonychus and a few others,
to disappears altogether in Epimechus, Ephelops, etc. A remarkable
character exists in the subcontiguous middle coxje of Magdalinops.
As will be seen further on, considerable inq)ortance has been attached
to the relative length of the ventral segments.
The .sexes can generally be separated without much difficulty by
keeping in view the following points :
Ma/e. — Beak stouter, more coarsely sculptured and generally more
o})aque ; anteniiie inserted nearer the aj)ex, or more coi-rectly sj)eak-
ing, the beak as already pointed out by Jekel (Annales de la Soc.
Entom. de France, 1864) is less prolonged beyond the insertion of
the antennie, the distance of the latter from the base is about equal
in both sexes.
Female. — Beak more slender, less coarsely punctured and more
shining ; anteniue more remotely inserted from the apex.
The third and fourth ventral segments appear to be a trifle shorter
in the males ; the fifth is generally longer and rounded in the female ;
shorter, subtruncate, or eniargiuate in the male, permitting the py-
gidium to become more or less visible from below. The latter is
more freely exj)osed in the male, rarely entirely covered by the apex
of the elytra, while frequently only partially exj)osed or entirely
concealed in the female.
NORTH AMERICAN COLEOPTERA.
179
The tibial armature, and especially the mucro of the posterior
tibiie, is more slender and longer in the male than in the female.
As is well known, all the members of the present tribe are phyto-
phagous, and the greater number, no doubt, spermo])hagous. A few,
like A. sycophanta, P. cratcegi, Coccotorus, etc., are said to breed in
galls. I regret that I have nothing new to offer in the life-history
of these insects.
Family CURCULIONID.E.
Tribe Anthonomini.
Mandibles bi-emarglnate and three-toothed at tip; gular peduncle
long ; oral organs small.
Beak cylindrical, long and slender; more rarely moderately stout
and shorter (Macrorhoptus, some Anthonomi). More or less curved
in all, but nearly straight in Macrorhoptus and Cionistes. Scrobes
commencing at a distance from the buccal opening (less remote in
the subgenus Paranthonomus) ; straight or somewhat curved ; directed
against the middle or lower segment of the eyes; more rarely (Mac-
rorhoptus, Cionistes, Pseudanthonomus and Ephelops) oblique and
directed beneath the eyes.
Antenme variable, long and slender in the great majority ; in-
serted at a distance from the apex ( less remote in Paranthonomus) ;
subbasal in certain Orchestes (Alyctus Thoms.). Scape long and
slender, rarely (Macrorhoptus, certain Orchestesj short and stout ; in-
crassate at its distal extremity and generally impinging against the eye,
except in Tachypterus and those genera having the scrobes oblique
and directed beneath the eyes. Funicle live to seven jointed, glab-
rous; first joint stout, generally elongate; following joints variable,
each with a verticel of six to ten stiff or flexible hairs; rarely
I Acalyptus and Euclyptus) entirely pubescent. Clava elongate oval
or elliptic, acuminate, pubescent; closely or more loosely articulate
(first joint strongly glabrous in Magdalinops, some Anthonomi and
Neomastix), rarely very elongate and very loosely articulate (Ta-
chypterus and in the subgenus Leptarthrus), or broadly oval and
closely articulate (Neomastix).
Eyes at least moderately large, roumled and remote from the pro-
thorax ; rarely (subgenus Anthonomorphus) small and subrostral in
their position ; widely separated above, and nearly flat or moderately
convex in most; rarely (A. elegans, leucosticfus ; Leptarthrus, Or-
180
WILLIAM G. DIETZ.
chedes) very prominent, and approximate upon the front; large,
transver.sely oval and approximate beneath in ]\Iacrorhoptus. In a
number of species the posterior margin of the eyes is more or less
free and elevated, in consequence of which its surface is directed
more anteriorly.
Head more or less rounded or conical, not deeply immersed into
the prothorax (except Cionistes).
Prothorax wider than long (except A. brunnipennis) ; narrowed
in front; anterior opening obliquely truncate (except Acalyptus).
Very rarely (Macrorhoptus, subgenus Anthonomorphus and Tricho-
baropsis) emarginate antero-inferiorly and giving a feeble appearance
of postocular lobes ; base bi-emarginate, produced in front of the
scutel ; latter small, oval or rounded, densely pubescent or scaly.
Elytra variable, generally wider at the base than the prothorax ;
striato-punctate (striae confluent at base in most Pseudanthononii).
The outer margin shows the following variation: in those species
having the elytra ample, that is, completely concealing the pygidium,
the outer margin of one elytron forms a continuous horizontal line
in its juxtaposition with the other and the outer stria unites with the
sutural stria at an almost right angle. On the other hand, in those
species in which the pygidium is freely exjiosed, the outer margin
of each elytron ascends towards the apex, forming an angle in which
the pygidium becomes more or less visible, and the outer and sutural
strife unite at a more or less obtuse angle. In the text, the term
dehiscent has frequently been used to denote the latter character,
which varies greatly in extent, being most strongly marked in A.
profimdus, elegans, etc., and scarcely noticeable in A. nebulosus, pe-
ninsularis, etc.
Prosternum short in front of eoxfe (long in Acalyptus, and mod-
erately so in Anth. ipfipes and disjunctus). Anterior coxte contigu-
ous, rather large and prominent ; middle coxje separated liy the
mesosternum (subcontiguous in Magdalinops) ; the latter generally
narrow, very rarely (subgenus Anthonomocyllus) wider than long,
between the coxie. Metasternum moderately long (short in Antho-
nomocyllus) ; side pieces narrowed posteriorly. Posterior coxfe
widely separated (only moderately so in Magdalinops).
Ventral segments variable in length ; subequal in Macrorhoptus,
Tachypterus, Magdalinops, and some Anthonomi. First and second
segments elongate (scarcely elongate, with the first segment short
behind the coxie in Anthonomocyllus ; very strongly elongate in
Ts’ORTH AMERICAN COLEOPTERA.
181
Anthonomopsis). Third and fourth segments shorter than the for-
mer, rarely (Alycodes, Elleschus and Euclyptus) very short. The
fifth segment, aside from sexual differences as noted before, attains
its greatest length in iVlycodes, Elleschus, Euclyptus and a few
species of Anthonomus.
The sutures are straight and deep, except the first, which is less
deeply impressed (almost obsolete in Anthonomopsis) ; the latter is
(aii’ved in Elleschus, Anthonomopsis and Euclyptus.
The pygidium varies in size ; it is oblique and concealed in both
sexes in Alycodes, Macrorhoptus, JMagdalinoj)S, Tachypterus and
Elleschus; more or less exposed, at least in the male in all the others.
The more perpendicular its position, the more freely exposed it be-
comes. It is indexed in some males, where it fits into the emargina-
tion of the last ventral segment ; this is most notably the case in
Coceotorus, to a less extent in Anthonomocyllus and Xeomastix. It
is narrowly excavated in a longitudinal direction in the subgenus
Paranthonomus.
Legs never very stout (except Nanops) ; thighs more or less cla-
\ ate and generally toothed. Tibire generally slender ; posterior of
male curved in Anthonomocyllus and Cnemocyllus ; toothed inter-
nally in A. elegans and Leptarthrus irroratns. The apical armature
requires more than a passing notice. It consists either of a hook,
unguiculum, arising from the apical articulating surface, curved in-
ward at almost a right angle with the tibial axis, or else a mucro, a
prolongation of the internal apical angle into a point, in the direc-
tion of or approximating to the longitudinal axis of the tibia. Being
morphologically distinct, I have found differences in the armature
of sufficient importance to be made use of in the separation of
genera. The anterior and middle tibiae are unguiculate, and the
posterior mucronate in the majority of genera. All are unguiculate
in Alycodes, Tachypterus, Magdalinops, Macrorhoptus, Chelonychus,
Anthonomopsis, Elleschus and Nanops. Acalyptus has the anterior
and middle tibiae unarmed, the posterior feebly mucronate, while in
Euclyptus all the tibiae are unarmed, and in Xanthus the armature
becomes very feebly developed.
Tarsi variable, never very stout (except some species of Elleschus) ;
frequently long and slender ; third joint bilobed, spongy or pubescent
beneath, fourth joint generally of moderate length (short in Elles-
chus, very long in several species of Cnemocyllus). Claws somewhat
approximate and armed with a large tooth in the great majority ;
182
WILLIAM G. DIETZ, M. D.
the tooth is either curved inward at the apex and approximate to, or
else straight and parallel with the tooth of the other claw. The
tooth is small and inconspicuous in a few Anthonomi and Nanops,
and especially so in Chelonychus, where the claws are also bent back-
ward. The claws are appendiculate, that is, armed with a broad tooth
beneath in Elleschus, Euclyptus and Orchestes, and entirely simple
and more widely divergent in Alycodes, E])imechus, Ephelops, Xan-
thus and Acalyptus.
The species of the present tribe are mostly small insects, a few
almost minute; none in our fauna, at least, exceeding 6 mm., or .25
inch, in measurement.* The vestiture consists of pubescence or
scales. In Anthonomoclneta the pubescence is intermixed with erect
seta?.

white, erect, club-shaped bristles, which are especially cousincuous on the sides
of the prothorax, where they are directed toward the median line, and are ar-
ranged in a single row on each elytral interspace. The ])rothorax is densely and
a trifle more finely punctured, with a broad stripe of pale brown scales along the
middle; sides paler. Long. 2 — 3 2 mm.; .08 — .13 inch.

TAC'll YPTKKUS gen. nov.
Head moderately convex. Eyes rather small, round and moder-
ately convex. Beak long and slender; scrobes deep, linear, directed
toward, but not quite attaining the eyes; antennne inserted at a dis-
tance from the apex, slender ; scajie not attaining tlie eye ; funicle
7-jointed, first joint long, 2-7 short. Clava elongate, acuminate at
apex, rather loosely articulate. Prothorax wider than long, con-
stricted at a|iex, sides rounded ; base bisinuate. Elytra wider than
the ])rothorax at base; each elytron protuberant at the base, fitting
into the emargination at the base of the prothorax ; strongly convex
and declivmus posteriorly, concealing the ])ygidium. Surface tuber-
culate or uneven, striae punctured. Prosternum moderate in front
of the coxae. Mesosternum rather narrow between the coxae. Meta-
sternum short, about as long as the first ventral segment at middle.
Abdomen broadly ovate, first and second segments moderately long,
subeipial, third and fourth shorter, fifth longer. Legs moderately
stout. Thighs feebly clavate, anterior bidentate, middle and poste-
rior unidentate. Tibiae somewhat compressed, anterior subangulate
about the middle, bisinuate; articulating surface oblicjue, all un-
guiculate at the a|)ex. Tarsi rather stout; first joint a little longer
than the .second ; third joint deeply bilobed, fourth moderate ; spongio-
})ilose beneath. Claws cleft, teeth convergent.
The type of this genus is Anth. quadrigibbus Say, a common spe-
cies found over our whole territory, and to which I have to add a
new s[)ecies. They are readily distinguished as follows :
Elytra strongly tuberculate, alternate interspaces more i)roininent. pubescence

Elytra feebly tuberculate, interspaces equal, pubescence sparse... coiisors n. sp.
1. T. qiia<li*igibbii!4 Say. Plate v, ligs. 3-3<i.
The generic description with the above synoptic reference, will
readily distinguish this well-known species from any other. A large
tubercle is sitiuited on the third interspace on the summit of the de-
clivity, another on the fourth nearer the apex. There are also some
irregular elevations on the filth and seventh interspaces. The elytra
are ti'ansversely imiiressed behind the scutellum, and this S])ace is
densely clothed wdtii wdiitish pubescence. The pi’othorax has three
narrow' lines of wdiitish ])ubescence, wdiile a lateral stripe of bright
yellow pubescence is continued upon the densely pubescent side
pieces of meso- and metathorax.

apex and almost straight ; striato-punctate. Scrobes short, oblique,
evanescent posteriorly. Antemue inserted about one-half ( S ) or
two-fifths ( 9 ) from the apex ; scape slender, impinging against the
lower segment of the eye; funicle rather stout, 7-jointed, first joint

Elytra distinctly striate and punctured, leaving the pygidunn, at
least in the male, more or less exposed, rrosternum short, very
rarely (A. rvfipes, disjunctvs) somewhat elongate in front of the

This genus contains by far the largest number of species, which
vary greatly, not merely in their general habitus, but also in more
important characters, possessing at least a subgeneric value. I have
deemed it, therefore, expedient to establish a number of subgenera,
in in-eference to still further increasing the number of those having
full generic value. As will be seen, I have included Coccotorus Lee.

A % specimen in j\Ir. H. Ulke’s collection, very recently received.
Strnctnrally, this species agrees very closely with the foregoing, but
the eves are nearly round, the elytra almost conjointly rounded at
the tip and all the femora are bidentate. In coloration and vestiture,
it is totally different.
A. pervilis n. sp. — ,'Vgrees with the preceding in all particulars, except the
following : ferruginous, underside of thorax piceous. Head not constricted
behind the eyes, which are scarcely convex; a transverse, deeply indented line
above the eyes. The pygidium is very little exposed. Long. 5 mm. ; .20 inch.
Hab. — Lower California.
A 9 specimen, received with the foregoing from INIr. H. Ulke for
determination. It is with some reluctance that I record this species
as distinct from peninsularu, but the strikingly different coloration,
which is not due to immaturity, the head not constricted hehind the
eyes and the deep, transverse indentation above the eyes, seems to
warrant its separation, until more extensive series of s[)ecimens shall
establish its identity with the former.
Suhgenus Trichobarapsis. ■*
A coarsely })ubescent species from Texas, having the prosternum
emarginate and the seventh joint of the fnnicle continuous to the
club, forms the type of this subgenns. The anterior and middle
femora are bidentate, posterior with a single tooth. The tibiae are
l)i-emarginate internally, and the armature well marked. The tarsi
are slender; claws broad and widely sejiarate, armed with a tooth
nearly as long as the claw.

In form this species resembles somewhat Trichobaris, without,
however, the denuded spots; through the emarginate prosteruum and
the outer joints of funicle continuous to the club, the |)resent subgenus
approaches Macrorhoptus, and through the former also Anthonomor-
phus.
Subgenus Leptarthrus.
Under this subgeneric name I have separated from Anthonomus
proper two new and peculiar species from Florida, in which the an-
tennal club becomes greatly elongated and the joints very loosely
articulate; the beak is slender. Antenme very slender, funicle 7-
jointed, with the first and second joint longer than the following

distinguished otherwise.
A specimen in Mr. Schwarz’s collection has the elytra more uni-

are a tritle more convex, and the tuberosities on the summit of the
elytral declivity are obsolete. I do not consider it specifically dis-

As already pointed out by LeConte (op. cit. ]). 109), this cannot
lie A. he/vohts Boh. (Sch. Gen. et Sp. Cure. vol. vii, 2, p. 224), as the
description “ feinorihus anteriorihus hreviter unidentatis, posticis
muticis,” and again, “Thorax latitudine postica nonnihil hrevior,”
does in no wise correspond with the species under consideration.
Subgemis Anthonomus.
I have hut little to add to the definition of the genus as here re-
stricted, to what has been given in the table. The fifth ventral seg-
ment of the male is hut rarely emarginate. The funicle is 6-jointed
in but a small number of species.
The present suhgenus contains by far the greatest number of spe-
cies, which j)resent structural differences of considerable importance,
and which I have made use of in subdividing the species into the
following groups :
Funicle seven-jointed.
Upper surface pube.seeut (scales, if auy, are arranged in spots or lines, except A.
concinnus) ; claws strongly toothed.
Elytra conjointly rounded at the apex; pygidiuin of % very little exposed;
pubescence dense, arranged in patterns on the elytra.
nebulosus Group.
Elytra not conjointly rounded at the apex ; pygidiuin, at least of the male, more
fully exposed ; pubescence uniform, or condensed in spots or lines
without distinct patterns.
Anterior femora bidentate gularis Group.
.interior femora unidentate.
Third ventral segment longer than the fourth; fifth segment shorter,
rarely as long as the fourth in the male.
Pubescence of elytra uniform, rarely condensed in spots or lines, and
without denuded patch or fascia. PI. vi, fig. I4...suturalis Group.
Elytra with spots or lines of condensed pubescence, enclosing a denuded
patch or fascia. PI. vi, fig. 15 sig-natus Group.
Third and fourth ventral segments equal or nearly so; fifth segment of
male longer than the fourth. PI. vi, fig. 16....scutellatus Group.
Upper and lower surface pubescent; claws armed with a small, inconspicuous
tooth juniperinus Group.
Upper and lower surface clothed with scales; tarsi long squamosus Group.
Funicle six-jointed.
Claws armed with a large, distinct tooth subfasciatus Group.
Claws armed with a short basal tooth ung-ularis Group.
nebulosus Group.
I have nothing fuither to add to the description of this group,
as given in the synopsis, except that the tooth of the claws is rather

shorter and more obtuse than in the other species with 7-jointed
funicle, in this respect resembling rather ^4. pyri, ulmi, ornatus, etc.,
of Europe. In fact, the two species belonging here, one of which
is introduced from Europe, are more characteristic of the fauna of
that continent than our own.
The two species are readily distinguished as follows:
More robust, anterior thighs bideutate, pubescence more squamiform.
iiebiilo^iiiis Lee.
More slender, anterior femur with a large triangular tooth, pubescence piliforni.
poiiioriim Linn.
\. iiebiilosiis Lec. — Oval, brownish piceous ; pubescence dense, rather
squamiform of a grayish, brown or fawn color and intermixed with very fine,
short hairs, forming distinct patterns on the elytra. Beak long, slender, mod-
erately curved, quadristriate, lateral striae deeper and longer, punctured and
scarcely pubescent. Antennae inserted remotely from the apex, rather long and
slender ; scape slender, paler than the rest; second joint of funicle slender and
longer than the third ; joints 3-4 slightly elongate, longer than the following
joints. Eyes convex, posterior margin free. Head convex, pubescent; occiput
more finely, front more coarsely and densely punctured. Prothorax more than
one half wider than long; sides more strongly rounded in front, strongly nar-
rowed anteriorly; apex feebly constricted and impressed at the sides behind the
anterior margin ; surface evenly, densely and rather coarsely punctured, rather
sparsely pube.scent with three narrow, paler lines. Elytra one-fourth wider at
the base than the prothorax, oblong, sides feebly rounded and gradually nar-
rowed to the tip, which is conjointly rounded ; strife impressed, |iunctures coarse
and rather closely placed; interspaces convex, punctulate; scutellum white; the
pubescence is arranged as follows : a trapezoidal basal space, a double curved
band commencing below the humerus and extending obliquely to the middle of
the suture, thence curving outward in a transverse direction to the outer margin ;
within the space included is another triangular area of pubescence; underside
of body and head clothed with squamiform pubescence. Abdomen less densely
and more coarsely pubescent, pygidium very little ( '^ ) or not expo.sed (f).
Legs moderately stout, thighs clavate, anterior bidentate, internal tooth lofig,
outer tooth small, triangular and connected with the former at the base. Tibiae
rather shorter and stouter than usual ; anterior pair curved near the base, pos-
terior near the apex : armature strong. Tarsi slender, pubescent beneath ; claws
armed with a rather short tooth, which is submedian on the anterior tarsi and
becomes almost basal on the posterior. Long. 3.75—4.25 mm. ; .15— .17 inch.
Male. — Pygidium carinate, depressed at the sides, fifth ventral
segment feebly lobed at the middle.
Eema/e.— Pygidium convex, fifth ventral segment bilobed at the
middle.

anterior thigh varies in prominence, and in one specimen before
me becomes almost obsolete, being replaced by several serratnres on
the outer margin of the internal, or large tooth. This modification,
however, could not give rise to confusion with the next species in
which the antei ior femoral tooth is much larger, and the external
margin perpendicular. In the majority of specimens examined the
pygidium is entirely concealed by the elytra.
.4. puinoriini Linne. Plate vi, fig. 12. — Less robust than the preceding,
dark brown or piceous, pubescence fulvous brovvn, intermixed with pale. Beak

conical, rather coarsely punctured and pubescent, more coarsely so and rather
concave between the eyes; frontal puncture small, but deep. Prothorax about
one-half wider than long, narrowed from the base, latter scarcely emarginate
each side, median lobe almost obsolete ; sides feebly rounded and scarcely con-
stricted at the apex, a curved impression behind the anterior margin ; surface

and deep, and like tbe striae more or less concealed by the pul)escence, latter
dense and less coarse than in the preceding species ; a subdenuded spot near the
base of the third interspace; an oblique fascia behind the middle, extending
from the seventh to the first interspace; a triangular spot on the declivity, with
its base on the first interspace ; scutellum, a few small spots on the disc and along
the margin of the oblique fascia, white. Beneath, thorax rather coarsely, abdo-
men more finely ])unctured and thinly pubescent, exce])t the prothorax. Legs
more slender, femora feebly clavate, unidentate, anterior femoral tooth very
large, acutely triangular, external margin perpendicular; tibim and tarsi as in
nebulosus. Long. 4 mm. ; .16 inch.
Hab. — Ohio.
A female specimen of this common European species was received
some years ago among specimens of nebuloms, to which it hears a
superficial resemblance. The less robust form and large, single tooth
of the anterior thighs, will readily distinguish the present species.
It is with some hesitancy that I introduce this species as occurring
in our fauna, based, as it is, on a unique specimen.

The species belonging to this group have the anterior thighs bi-
dentate, the i)ygidium rather freely exposed, and the j)ubescence
coarse or sparse, without any attemi)t at forming distinct j)atterns.

Each elytron has a fnscons reflection along its disc. This species
could only be confounded with the following, from which it is dis-
tinguished by the characters given in the table.
.4. Virgo n. sp. Plate vi, fig. 13. — Eesembles gularix in form atid pubescence.
It differs as follow's : Beak more densely punctured, less shining; median ele-
vated line, scarcely attaining the base. Head opaque, densely and finely punc-
tured, front with an imjjressed line. Prothorax rnfo-piceous. Elytra bright
ferruginous, periscutellar space and along the suture dark piceons ; anterior tibite
fringed with hair along the inner margin ; anterior tibiae of male curved inward
near the apex, and the internal angle produced in form of a broad hook. Legs
and abdomen along the middle ferruginous. Long. 2.5 — 3.4 mm. ; .10 — .15 inch.

A. riifipeiiiiiN Lee. — Of the same general liahitus as gularis, but smaller,
and the pubescence a little more pronounced. It differs in the following char-
acters: Piceous, elytra ferruginous. Beak shorter and stouter, opaque; striolate
with several rows of remote punctures, lateral elevated line more prominent,
median not extending u])on the front. Anteunse pale rufous, club dusky, second
joint of funicle elongate. Eyes convex, but not free behind. Prothorax scarcely
one-half wider than long. Elytra semi-opaque, strife and punctures more strongly
impressed ; interspaces slightly convex, finely rugose, each with several irregular
rows of punctures ; scutellar space and along the suture darker; the pubescence
on the under surface is white and as dense as in gularis ; the legs are a trifle
stouter. Long. 2.2 —3 mm. ; .09 — .12 inch.
This species varies somewhat in size and coloration, some speci-
mens are entirely rufous; the pubescence, also, is more pronounced
in some than in others.
LeConte’s description: “thorax a little longer than wide,” does
not correspond with any specimens before me, nor does the statement
in his synoptic table of species — that the anterior thighs are uniden-
tate. The smaller, outer cusp is well marked in all but a single
specimen, in which it is nearly obsolete.
Hab. — Pennsylvania (LeConte), Illinois, Texas, Florida.
suturalis Group.
The species belonging to this group have the anterior thighs uni-
dentate. The ventral segments decreasing in length from the second,
the third segment being always longer than the fourth, and this lon-
ger than the fifth, at least in the male, except corvulus, where the
fifth is scarcely shorter than the fourth segment. In general, the
species are rather sparsely pubescent, except suhguttatus, all the
femora armed with a single tooth (hind pair mutic in melancholwm),
although the tooth of the posterior pair becomes nearly obsolete in
specimens of siibguttatus and mondus. The tarsi are more slender
than in the next group, and the first joint longer than the second;
the elytra are without a denuded fascia ; lines and spots of pubes-
cence do not occur, excejit in suhguUatus, more rarely in flavicortds.
The species are closely related, and while it is not difficult to rec-
ognize typical specimens, aberrant forms occur whose exact position
it may not be always easy to determine.
I have arranged the species as follows :
Entirely rufo-testaceous or ferruginous, underside of thorax generally darker.
Elytra finely striate, punctures small, interstices flat, wide; antennae slender.
Elytral interspaces rugose, prothorax not constricted at apex ; larger species.
Bolfei’i.
Elytral interspaces smooth, prothorax strongly constricted behind the ante-
rior margin riibellus.

Hah. — Lake Superior.
A unique female in my collection. It might be confounded with
the preceding species, its nearest ally, but differs especially in size
and form of prothorax. From eonfums it is distinguished by the
much less pronounced elytral sculjtture and the intersiaices being
smooth.
COiiriiSii<$ n. sp. — Similar in form to A. Bolteri ; rufo-testaceous, pubes-
cence coarser and more conspicuous. Beak a little stouter and less curved ; me-
dian elevated line very feeble, or almost obsolete; more densely and coarsely
punctured. Antennge stouter, second joint of funicle less elongate, but always
longer than the third. Eyes scarcely convex, posterior margin uot free. Head
a trifle more coarsely punctured. Prothorax constricted at the apex, bisinnate
at the base. Elytra coarsely striato-puuctate, punctures large and round, almost

undeiside, legs and tarsi as in Bolteri. Long. 2. .3— 3 mm. ; .09 — .12 inch.
Hab. — California, Montana, Wyoming.
The three [treceding specie.s are very closely related, but more ex-
tensive series are necessary, to prove them as mere variations of one
species. Two specimens in Dr. Horn’s collection, from Montana,
which I refer to the present species, show a decided similarity to
Bolteri in the less coarsely punctured, elytral strim, more convex
eyes, le.ss conspicuous pubescence and larger size.

Occurs probably in all the Atlantic, Middle and Western States.
Varies somewhat in coloration, but the elytra and the abdomen are
always fen-nginons. The anterior thoracic margin is generally retl-
dish. The legs are either bright ferruginous, or else pitchy black,
without having observed any intermediate variations. One specimen
in Dr. Horn’s collection from South California has the elytra! striae
rather supei’ficial and the punctures smaller. I have no doubt of
the identity of this species with A. h(zmatopus Boh.
A. suturalis Lee. — Similar in size and form to sycoplianta, but a trifle less
robust, pitchy black, elytra more or less ferruginous, tibim rufo piceous, tarsi
paler, the beak is oi>aque, feebly striate and punctured. Antenute, head and eyes,
as in that species. Prothorax transverse, more stroTigly rounded on the sides
behind, narrowed in front, constricted and transversely impressed behind the
anterior margin; surface more densely and finely punctured, base bisinuate.
Elytra! strife not strongly impressed; punctures small, not verj’ close; inter-
stices flat, more shining and very finely rugose; scutellum clothed with white
pubescence ; under surface as in that species, but the pubescence is a little more
dense and squamiform ; the tibite are a little stouter, the tarsi longer, and the
claws larger; the tooth of the latter is also a little larger. Long. 2.7— 3 mm. ;
.11 — .12 inch.
Hub. — Eastern and Western States.
The red apical blotch varies greatly in extent, leaving always,
however, the suture and scutellar space black. Larger sized speci-
mens with the elytra almost entirely red, may be confounded with
A. virgo, from which the present species differs by its nnidentate an-
terior femora, more strongly elavate thighs and smooth rostral carina.
Fi-om sycophanta it is to be distinguished, aside from coloration, by
the sides of the ])rothorax being more strongly rounded and the
apical constriction, the punctures also, are less coarse and less dense,
and the elytra more shining.
A specimen in Dr. Horn’s collection from Iowa, while evidently
belonging to the present sjiecies, has the ])rothorax quite coarsely,
though very closely, punctured. The elytra are entirely ferruginous,
with a triangular basal space dusky.

<)n account of the squamifonn pubescence, which is readily removed,
this species might he referred to the sqnamosus group, with which,

A specimen in my collection, taken in this neighborhood (Hazleton,

specimens from Texas in Mr. Hike’s collection are a little less robust,
with tw'o interrujjted lines of condensed pubescence on the elytra,
thereby forming some similarity to subguttahis. From nigriuus, witii
which the present species might be confounded, it is to be distin-
guished by the less coarsely and less densely |)unctured prothorax,
testaceous antennie and less slender legs.

Only two female specimens in Dr. Horn’s collection are before me.
Bears a striking resemblance to Eprinechm viwiicus, described further

toothed claws.
Since writing the above I have received a specimen from Dr. Horn,
which has entirely the coloration of a typical A. snturalls, the elytra
being bright rufous with the exception of a triangular basal space ;
it is easily recognized, however, by the form of the jirothorax and
the le.ss shining elytra.

feebly clavate, all armed with a small, acute tooth : tibiae almost straight, and at
the apex, like the tarsi, brownish. Long. 1.5 — 2.2 mm. : .06 — .09 inch.
Hah. — Pennsylvania, Massachusetts, District of Columbia, Illinois,
W isconsin, Michigan, Texas, Arizona.
Easily recognized by its small size, shining black color, coarsely
punctured prothorax and s])arse pubescence. The pubescence is
easily rubbed off, giving the insect a still more shining appearance,
and on sujierficial examination, might give rise to confusion. Speci-
mens are before me of a brown color, probably due to their being
immature.

A specimen in Mr. Dike’s collection, from District of Columbia,
differs from the typical form by the pubescence being jiale yellowish,
sparser and less coarse.
This species might jiossibly be referred to the signatus group, with
which, however, it has no close relationshiji ; the first and second
ventral segments are relatively shorter, and there is no denuded
elytral fascia. Dr. LeConte indicated this species under A. scutella-
tus Gyll. ( Proc. Amer. Phil. Soc. vol. xv, p. Uh)), hut failed to de-
•scrihe it.
sig-natus Group.
This group contains species of rather small size, and presenting a
similarity of habitus which makes them easy of recognition. They
agree with those of the preceding group in the abdominal formation;
the first and second ventral segments, however, are genei’ally longer
and nearlv ecjual in length, the gradual decrease in length commen-
cing with the third segment, instead of the second, as in that grouii.
The elvtra have a post-median denuded patch or fascia, surrounded,
in the fresh state at least, by spots or lines of pubescence. They
difier very little in sculpture, and are to be distinguished rather by a
general assenddage of characters and habitus. The first two tarsal
j(dnts are equal, or nearly so.
The following table, supplemented by the Sjiecific description, will
enable the student to identify his species:
Elytral interspaces equal, or nearly so.

moderately large, close set and becoming smaller towards the lateral margin ;
inter.spaces slightly convex, shining with an irregular row of fine punctures;
the denuded fascia extends from the side to the third interspace, another de-
nuded spot on the second interspace ; scutellar space and along the suture darker ;

densely clothed with white, squamiform pubescence. Abdomen sparsely i>ubes-

Varies considerably in size, and still more so in coloration, from
pale testaceous to almost pitchy-black ; the latter variation might
readily be mistaken for the next species, from which it differs by the
less rounded prothorax and stouter antennal funicle ; the beak also
is more densely punctured and less curved. The following variety
is well marked, and deserves special consideration :
\bir. pallidus. — Testaceous ; head dark piceous ; rostrum and
pectus infuscate. Prothorax nearly twice as wide as long ; the scn-

Varies in coloration ; fresh specimens have the elytra more bright
red, which in dried specimens changes to a dark brown or even
blackish color. The denuded spot can generally be recognized by
its darker color, and being surrounded by a line of pubescence,
which is liable, however, to abrasion. Why Prof Riley should con-
sider this species identical with sir/natus (Agric. Report 1885, pp.
276-282) I cannot understand, for, aside from the difference in length
of the second joint of funicle which is always evident in fresh and
can be demonstrated on old specimens that have been relaxed, the
]>resent species is less robust, thorax less rounded on the sides, and
suture always darker. According to Dr. John Hamilton it is rarely
found after the first week in June, whereas signcdus is found always
during the whole of Summer on various plants and shrubs, while
the former is generally tidcen on Huckleberry.

This species greatly resembles rufipennis of the gidaris group, but
is smaller, and differs further by the front being sidcate, the anterior
thighs with a single tooth and the posterior thighs mntic.
The ffrst two ventral segments tire relatively shorter in this than
the other species of this group, and the spots of condemsed pubescence
on the elytra give it a peculiarly striking appearance.

Hab. — Lower California; exact locality not stated.
A % and 9 specimen in Mr. Dike’s collection, who received it
very recently from the above locality.
The mesosternum is moderately wide between the coxte, where it
ends in an elevated, transverse ridge, and slojtes very gradually in
front. The third and fourth ventral .segments are of e(jual width,
and the fifth distinctly longer than either ; the pygidium is freely
visible from below.
This species, although very distinct, is closely allied to fiavicornis,
nigrinns and albopiloms. It resembles fiavicornis so closely that, if
viewed from above, it cannot be distinguished, except by its somewhat
greater size ; the abdominal formation, however, is strikingly different,
the beak, legs and tarsi much more slender; the first j'oint of the
anterior tarsi twice as long as the second, while equal in fiavicornis.
From the next species it differs by its being more robust, the beak
more slender, thorax less coarsely punctured, the femoral tooth spini-
form, the anterior and middle tibim curved near the aj)ex, and the
more slender tarsi with the first joint nearly twice the length of the
.second. The elytra, also, are a little more strongly striato-punctate,
and the ]nibescence much more conspicuous than in that species.

A single 9 in my collection found among a lot of loose material
sent me years ago hy Mr. H. Ulke, of Washington, and labeled
“ Virginia.”
This species is an exact reproduction of A. ungularis in form, color
and pubescence, but for the 7-jointed funicle, absence of elytral
fascia and very slender tooth of claw, it could not possibly be dis-
tinguished. The fifth ventral segment is longer than the preceding.

WILLIAM G. DIETZ, M. I).
This species, at once recognized by its pale testaceous color and
dark elytral spot, has a remarkable similarity to Nanophyes trans-
verms Aube of Southern Europe, and which, according to Desbro-
(‘liers,* was described by Chevrolat as Anthonomus juniperi.
squamosus Group.
Contains all those species with 7-jointed funicle, in which both the
upper and under surface are ])redominantly clothed with scales.
The scaly vestiture, while dense in most of the species, is sparse and
intermixed with a fine pubescence in some. The scales also vary
from almost round to very elongate, piliform. The ventral segments
are less unequal than in the majority of the pubescent species. Some
of the vittate forms shoAV great similarity to the species of the sub-
genus Cnemocyllus, from which they differ merely by the hind tibise
of the male not being dissimilar from those of the female.
The species may be tabulated as follows :
Stout species ; all the femora armed with a tooth.
Anterior thoracic opening very oblique, prosternum short in front of the coxai.
Elytra without transverse, partly denuded fascia.
Beak and antenufe slender; legs reddish, or rufo-piceous.
Larger; beak long and very slender; first and second joint of funicle
elongate.
Not densely clothed with scales, which are more or less piliform ; color
pitchy-black, legs rufo-piceous ater.
Densely clothed with oval scales, reddish t<t rufo-pii-eous. legs rufous.

Closely allied to squamosus, from which, indeed, it ditiers but little
structurally, excejit in the form and density of the scales. Comjiarison
will show at once that it should not be placed among the pubescent
species.

Varies considerable in form, coloration and density of the scalv
vestiture. The alternate elytral intersjiaces are paler in some speci-
mens, giving them a vittate appearance, more or less marked.

Might easily be mistaken ^ovhirtm; in fact, the descriptive phrase,
as given by LeConte of that species, “ densely clothed with coarse,
scarcely squamiform, ochreous jtubescence,” a|)plies far better to the
sjtecies under consideration ; it is, however, less elongate, the eyes
slightly encroaching u|)on the front, the prothorax distinctly wider
than long, the thighs more strongly clavate, and both anterior and
middle armed with a tooth. The peculiar curved projection of the
terminal hook of the anterior and middle tibise I do not remember
of having observed in any other sj)ecies. One of the specimens has
a strongly marked, oblique impression each side of the jirothorax.
The unusual occurrence of this kind of sculpture in the present
tribe is no doubt due to some disturliance in the earlier stages.

Subgenus Cnemocyllus.
Under this subgeneric name I have included all those species
which have the posterior tibite dissimilar in the two sexes, those of
the male being more or less curved, while in the female they are
straight, or nearly so. This curvature varies greatly, being most
marked in ornatulus and figuratus, and least in Ugatns. The fifth
ventral segment is more or less elongate, except in sabvittatus, or-
natulus and jiguratus, and very long in inermis. The tarsi are never
short and broad, but are very long and slender in a few sj)ecies.
The tooth of claw varies considerably in development. The form
varies from oval to elongate, and the integument is clothed with
scales, which, in most of the species, form lines or vittae after a com-
mon pattern, as follows: A pale line on the fourth interspace com-
mencing about the middle and variable in extent, another vitta on
the sixth interspace commencing at the base and extending to about
the middle; in addition to these there is in some a darker patch or
fascia on the sides behind the middle. The prothorax is generally
vittate ; the funicle of the antemue is either 6- or 7-jointed.
The species occur in the Western and Southern States, are closely
related, and require great care to be distinguished. The following
table, sujiplemeuted by the descri|)tions and figures given, will, how-
ever, enable the student to positively identity them.

mens of pauperculus, from which, however, it is distinguished aside
from structural differences by its bright ornamentation, more trans-

I am not at all certain about the identity of this species, as Le-
Conte describes the thighs as being unarmed. I have only four
specimens before me, in all of which the tooth of the anterior pair
is discernible, but it is quite possible that, on account ot its small
size, it had been overlooked by that author. Two specimens in Dr.
Horn’s collection have the upper surface somewhat mottled with
brownish scales.

A male and female specimen in my collection only very recently
received. This species resembles camis very closely in form and
coloration ; it differ.s, however, by its greater size, smaller and more
densely placed scales, the elytra more gradually rounded to the apex,
the pygidium more freely exposed, and the hind tihite of the male
strongly eurv'ed ; the fifth ventral segment is longer than the pre-

defined, elevated lines. Antennae somewhat stout, second joint of funicle elon-
gate, slender and longer than the third, which is a trifle longer than the fourth,
club dusky. Eyes almost flat, posterior mai'gin .slightly free. Head convex,
punctured and densely squamose; an impressed frontal line extending upon the
base of the rostrum. Prothorax one-third wider than long, sides feebly rounded,
subparallel behind, strongly narrowed and distinctly, though not suddenly con-
stricted at the apex ; surface densely, though not coarsely itunctured, indistinctly
trivittate. Elytra a little wider at the base than the prothorax, oblong-oval,
almo,st parallel on the sides, gradually rounded to apex behind, coarsely sti iato-
punctate, striae broad and deep, punctures large, oblong and closely approximate ;
interspaces convex, roughened ; with the scaly covering intact, the latter appear
wide and flattened, and the striae, and punctures not entirely concealed. Legs
moderate, femora feebly clavate, anterior feebly toothed ; tibiae slender, anterior
and middle slightly bisinuate internally, posterior of male regularly, but not
strongly curved ; tarsi slender. Long. 2 — 2.2 mm. ; .08— .09 inch.

The pygidium is more or less freely exposed, and the fifth ventral
segment longer than the fourth in both sexes, though more markedly
so in the male, while it is foveate in the female. In well-marked
specimens a j^osterior pale vitta on the fourth and an anterior one on
the sixth interspace, as well as a post-scutellar line are more con-
spicuous ; the darker, lateral space is generally ill-defined.

Dr. Horn, who, in this instance also, has kindly made the com-
parison with the type in the LeConte collection at Cambridge, has
found the funicle to consist of only six joints and not seven, as erro-
neously stated by LeConte, and which had led me to doubt the
identity of the present species with the one described by LeConte.
This species is very closely related to the following, with which it
has heretofore been confounded in collections. A specimen from
Jacksonville, Fla., in Mr. Schwarz’s collection, I refer, with some
doubt, to the present species; it has the beak a little shorter and
stouter, the second joint of funicle a little shorter than the third,
outer joints wider ; the elytra a little wider at the base and not wider
posteriorly, sides feebly rounded, punctures close set and somewhat
transverse, interspaces more roughened, and the anterior femora
more strongly clavate ; it is entirely denuded of scales.
A. li$;atiis n. sp. Plate vi, figs. 24, 24«, 246. — Very closely resembles elon-
gatus in form, sculpture and coloration, and is distinguished from that species by
the following characters : the second and third joints of the funicle are a little
more slender and of nearly equal length ; the prothorax more strongly rounded
at the sides and more narrowed anteriorly. Elytra not wider at the base than
the prothorax with the sides a little more rounded ; the scales are of a more
yellowish color instead of the white, and less easily removed, the markings less
marked ; the dark denuded fascia extends from the sides to about the fourth
interspace ; the tibiae are more slender and the posterior of the male simply
emargiuate along the internal margin and entirely straight in the female. Long.

A unique S taken by me some years ago. The occurrence of
5-jointed funicle in the present genus is certainly remarkable. In
general appearance the species resembles incipiem ; the color is darker
than in any other species.

This new genus is established upon two small species from the
Atlantic States, differing from Anthonomus in the 5-jointed funicle
and the broadly ovate, antennal club.
Beak long, not very slender, |)unctured and striate; scrobes com-
mencing near the middle and directed against the lower segment of
the eyes. Antennae slender, scape straight, moderately incra.ssate at
its distal end; funicle 5-jointed, first joint long and robust, joints 2-
5 nearly equal, outer joints a little wider, clava broadly oval, closely
articulate, basal joint shining. Eyes moderately convex and slightly

simple, are less slender and less divergent, the lobes of the third tarsal
joint strikingly narrow, a character 1 have not observed in any other
Anthonomid ; the almost concealed pygidinm, and lastly the dense,
imbricate, scaly vestitnre, present a group wdiich might be considered
to possess more than specific value. I prefer, however, to leave it in

to me insufficient characters.

The simple claws, covered pygidiiim and short third and fourth ven-

Erirrhinns. The formation of the antenme and the general habitus

One male and two female specimens. Coll. Dr. Horn and mine.
I captured my specimen ( S ) some years ago on oak, and has served
as the type of the above description. One of Dr. Horn’s specimens
agrees in all particulars (except sexual differences) with mine, while
the other has the denuded fascia of less extent and the interspaces
not denuded near the base.
I have made careful comparison with well authenticated specimens
of this species from Europe, and can discover no difference, except
that a small denuded spot each side of the thorax is wanting in our
specimens, but as this also occurs in one of my European specimens,
it is probably of but subordinate value.
E. ppisitus Say. Plate vii, figs 35c, 35d. — Elongate, ferruginous,
mottled with pale yellowish and fawn-colored pubescence. Beak punctured.
Prothorax rather finely and not densely punctured. Elytral strife with large,
closely pLaced punctures; a large scutellar spot and another somewhat rhomboidal
space behind the middle connected along the suture, of darker color. A trans-
verse fascia of grayish pubescence immediately behind the posterior dark space;
underside punctured ; the claws are slender and armed beneath with a large
rectangular tooth at the base. Long. 2 — 3.3 mm. ; .08 — .13 inch.
Hab. — Atlantic States; Michigan, Georgia, Kansas, New iMexico,
Oregon, California.
A very variable species. The dark elytral spaces are almost ob-
solete in some specimens.
Mr. Thos. Casey very kindly has sent me a typical specimen of
his E. callforuicus. It is entirely pitchy-black, resembling in this
respect rather bipunetatus ; legs a trifle paler. The beak is less
punctured, shining, and the second joint of the funicle is longer than
the third. In all other respects it agrees with ephippiatus, from
which it does not appear specifically distinct, but forms a marked
variety.
E. n. sp. Plate vii, fig. 35d. — Elongate elliptic, femigiuous.
not very densely clothed with whitish, squamiform pubescence. Beak rather
slender and moderately long, punctured and somewhat shining; substriate
and rather densely scaly from base to about the middle. Antennse slender;
first joint of funicle long and slender, second a little longer than the third,
outer joints hut little wider. Eyes as usual. Head punctured, occiput sparsely
pubescent, densely squamous between the eyes. Prothorax wider than long,
broadly rounded on the sides and very little wider at ba.se than at the apex.

which is not constricted, smooth dorsal line short, just in front of the middle;
punctures rather small and close set. Elytra elongate, about one-fourth wider
at the base than the prothorax ; sides nearly straight for three-fifths their length,
thence graduallj" narrowed to apex, w'hich is subacuminate ; strise moderately
impressed, punctures small, closely approximate; inter.spaces nrarly flat; pu-
bescence nearly equally distributed ; underside finely punctured and pubescent.
Legs rather slender, thighs feebly clavate, anterior armed with a small acute
tooth, which is represented on the middle and hind pair by an acute angle, less
marked on the hind femur; tarsi less robust, fourth joint extending considerably
beyond the third ; claws armed beneath with a short obtuse tooth. Long. 2.8--
3 mm. ; .11 — .12 inch.
Hah. — Arizona, Kentucky.
Two specimens, male and female, in Dr. klorn’s collection. A
very distinct species and unmistakable members of the present genus.
The rather slender beak and toothed femora are anomalous.
ORC'IIEXTEN 111.
The eyes clo.sely approximate above and the saltatorial })o.sterior
femora make the recognition of the species of this genus an easy
matter. "J'he beak, variable in length and thickness, lies between
the anterior legs during repose : the scrobes commencing about the
middle or even near the base; scape of anteniue not long ; funicle
6- or 7-jointed. The prothorax is relatively small. The elytra oval
or elongate-oval, wider than the prothorax, with the humeri rounded.
In reviewing the species I shall give only sufficient descriptive
matter which, in connection with the synoptic table, will enable the
student to identify his material. To the species heretofore known I
have to add one new species.
They may be tabulated as follows :
Funicle of autennse 7-jointed.
Elytra with patterns of pale pubescence.
An anterior and posterior transverse baud, always con.s]iicuous.
Anterior fascia wide, legs partly rufous epliippiaf US.
.\nterior fascia narrower; legs entirely black ssilicis.
A faint subbasal, transverse band only iiigor.
Elytra unicolorou.s, black.
Hind angles of jtrothorax rounded or rectangular, elytra without lateral
spine parvioollis.
Hind angles of prothorax acute; elytra with a subhnmeral spine.
arinatiis.
Funicle 6-jointed.
Hind femora strongly thickened.
Pubescence long and coarse, brownish pul»t*i*ulus.
Pubescence fine, sparse and whitish.
Black, thoracic jiunctures large, irregular; elytral interspaces coarsely
rugose can us.

Black, thoracic punctures moderate, round ; elytra! intersj)aces almost
smooth, shining pallieoriiis.
Black, elytra and abdomen red Itefiileti.
Hind femora scarcely thickened.
Legs rufous riifipes.
Legs piceous Var. iiiiiiiitiis.
O. epliippiatiis Say. — Robust, oval, piceous; beak, atitennje and legs ru-
fous. Prothorax small, rufo-piceous, not densely clothed with whitish pubes-
cence. Elytra oval, much wider than the prothorax ; anterior two-hfths and a
transverse post-median fascia rufous, or rufo-piceous and densely clothed with
white pubescence and connected by a line on the second interspace ; femora,
especially the posterior, wholly or in part piceous. Long. 2.5 — 3 mm.; .10 — .12
inch.
Hab. — Pennsylvania, Iowa, Illinois, California, Wisconsin.
Allied to 0. rujUarsis Germ, of Europe.
O. saliciN Linn. — Similar to the preceding, but smaller and less robust
Black, antennse and tarsi rufous; anterior elytral fascia narrower than in ephip-
piatus, about one-third from the base, irregular, prolonged along the sutural in-
terspace to the scutellum in front and extended along the second interspace
posteriorly, but not connected with the posterior transverse hand which is nar-
row and angulated. Long. 2.5 mm.; .10 inch.
Hab. — California, Wisconsin.
This is 0. subhirtus Horn. Careful comparison of Dr. Horn’s
types with specimens of the European species in my cabinet leave
no doubt of their identity.
O. iiiger Horn. — Rather robust, subovate ; black, anteniife piceous, clothed
with short pubescence, which is black on the upper and whitish on the under
surface; scutellum densely white pubescent; an inconspicuous, transverse fascia
about one-third from the base and consisting of sparse white pubescence. Long.
2.8 mm. ; .11 inch.
Hab. — Illinois, Michigan, Pennsylvania.
The white scutellum is in striking contrast with the rest of the
su rface.
O. pai'vic'ollis Lee. — Entirely black, oblong-oval with scarcely any lustre.
Prothorax coarsely and rather densely punctured ; hind angles subrectangular,
somewhat rounded. Elytral interspaces very rough. Long. 2.8 — 3 mm. ; .11 —
12 inch.
Hub. — California, Nevada, Colorado.
Distinguished from the three preceding species by the absence of
elytral markings and from the following by its coarse sculpture,
rounded posterior angles of thorax and the ninth elytral interspace
not produced in a sjiine.

Hab. — Allegheny, Pa. A single female specimen. Collected and
kindly given me hy Dr. Hamilton.
Very ditferent from any other Orchestes known to me and re-
markable for its very convex form, shining surface, acute posterior
thoracic angle, and the acute spine of the ninth intersjtace.
O. puberiiliis Boh. — Elongate oval, black, anteniiie and legs testaceous,
densely clothed with long, coarse, gray or yellowish gray pubescence; funicle 6-
jointed; scutellum clothed with white pubescence. Elytra regularly oval, hu-

O. riifipeis Lee. — Elliptic, smaller and less robust than any of the preceding
species. Black, thinly pubescent: antennae aud legs rufous: hind femora feebly
incrassate, more or less piceous. Long. 2 mm. : .08 inch.
Closely allied to the European 0. foliorum Miiller, from which it
appears to differ by the prothorax being a little more transverse and
not rounded in front.
O. minutus Horn is a variety of the above with the legs entirely
piceons. It occurs in California and Colorado.
XA\TIIUS gen . nov.
I have established this new genus upon two very small, testaceous
and thinly pubescent species having the claws simple, divergent, aud
the tibiae almost truncate at the tip, with the armature very small.
Beak long, rather slender and nearly straight, a little widened to-
wards the tip, not striate ; scrobes straight, attaining the eyes, which
are convex. Antenme moderately stout, inserted two-fifths ( S ) or
one-half ( 9 ) from the apex ; scape slender, impinging against the
eye ; funicle 7-jointed, first joint stout, second and third nearly equal,
outer joints transversely rounded ; club rather loosely articulate ;
front sulcate. Prothorax wider than long, feebly narrowed in front
and slightly constricted behind the anterior margin. Elytra a little
wider at the base than the prothorax, striate and punctured ; me-
sosternum moderately wide between the coxie, declivous in front :
first and second ventral segments moderately long, third and fourth
shorter, equal ; fifth not longer than the fourth in the male ; py-
gidium freely exposed in both sexes. Legs moderately slender,
thighs feebly clavate ; tibiae straight, slightly widened towards the
tip ; anterior and middle with a very small, scarcely perceptible
hook, posterior feebly mucronate at apex ; tarsi with the third joint
broadly bilobed ; claws simple.
The two species are amongst the smallest in the tribe and are
distinguished as follows :
Larger, rufo-testaceous ; prothorax more densely pimctured, ])ubescence con-
spicuous
Smaller, pale testaceous: jirotborax remotely punctured, pubescence very fine.

WILLIAM G. DIETZ, M. D.
The type of this genus is a small testaceous insect without close
relationship in any direction, except, perhaps, Acalyptus, with which
it agrees in the somewhat flattened thorax, unarmed tibioe and the
formation of the funicle. It agrees with Alycodes and Elleschus in
the abdominal formation and appendiculate claws, but the fifth ven-
tral segment is very long, and it is very different in other respects.
E. tesf sicens n. sp. Plate vii, figs. 39, 39a, 39b, 39c. — Elliptic, testaceous,
almost glabrous. Beak shiuiug, with a few remote punctures. Prothorax rather
closely and finely punctured, with an ill-defined, smooth dorsal line extending
from the anterior margin to about the middle. Elytral striie impressed, punc-
tures moderate, close set; interspaces scarcely convex, slightly roughened ; under
surface remotely punctulate. Long, nearly 2 mm. ; .07 inch.
iTa6.— Buffalo, N. Y.
A unique 9 in niy collection. Easily recognized by its pale color,
ventral formation, unarmed tibise and apj)endiculate claw’s. In ap-
pearance it resembles Notolomus basalis, without, however, the dark
basal spot of the elytra.

The species of .4GRIL.ITS of Boreal America.
- BY GEORGE H. HORN, M.D.
The first attempt at a comparative study of our species was made
by Dr. LeConte in his “Revision of the Buprestidie of the United
States (Trans. Amer. Philos. Soc. xi, 1859),” in which thirty-two
species wei’e recognized and eight previously described enumerated
as unknown. In this essay we find an important use of the form of
the claws as the basis of a primary division of the genus in groups.
Singularly the study of the claws was carried no further, owing
probably to the small material which furnished the basis of the
work. It is also to be regretted that but little attention was paid to
the sexual characters, and, as if by accident, only an occasional
allusion is made to the form of the prosternal lobe. Of the thirty-
two species described, twelve were represented by single examples,
and of the remaining twenty nearly half were represented by not
more than two. While this condition rendered the study at the time
easy and satisfactory, the further accumulation of material makes it
absolutely necessary to refer to the types for determination.
In 1873 (Proc. Acad. Nat. Sci. Phil.), Mr. G. R. Crotch attempted
a brief review of our species, which is notable for the insufficiency
of his comments in one portion of the paper and the numerous inac-
curacies throughout, especially in the analytical table. The value
of the Carina of the pygidium was first recognized in his paper, and
some attempt made to use the sexual characters as a means of sepa-
rating the species.
The species of the regions to the south of our limits have been
studied b}^ Mr. Waterhuuse (Biol. Cent. Amer. vol. ii, pt. 1 ) with
fairly good results, but the species of that region are so entirely
different from our own in facies and depend for their separation on
characters not applicable in our fiuina, that his work has been of no
assistance in the preparation of this. In this essay Mr. Watei-house
has separated one of our species (pulchellus), which has an equivalent
in Mexico, from Ar/rilas under the name Engyaulus, but for reasons
which will be found under our species, the genus is not considered
well founded.
278
GEO. H. HORN, M. I).
The species described by Gory are barely recognizable, and the
figures give but little aid. He seems not to have known of the
species described by Say, or else purposely disregarded them.
It being veiy evident that the unsatisfactory work ])reviously done
with our species w'as due to insufficient material, and the neglect of
an examination of the sexual characters, no attemi)t has been made
by me to record my observations until reasonably full series had been
obtained with the sexes of each species represented. In the following
pages but one species is represented by a single specimen, and of
about four others two of each have been examined.
As a general rule, our species are .not marked by any great surface
irregularities, such as deej) thoracic depressions and strongly elevated
elytral costte. The only exceptions aie cavaius and Couesii, the
former being represented in Mexico and the other may also be. At
ti]) the elytra are simjdy acute or rounded, never divergent, and
variously formed as in many of the INIexican species. The colors
are never very brilliant, nor is the ornamentation by pubescent spots
very striking. The monotonous aspect of our species has com])elled
a search for structural characters wdth very encouraging results, for
with such characters, the limits of species may be more accurately
defined notwithstanding any variation which may occur.
In order that the systematic portion of this work may be the better
understood, the various portions of the body showing important
modifications will be reviewed consecutively.
Antenna. —The form of these organs seems to have been entirely
neglected. In some species the antenme are slender and long (PI.
viii, figs. ]1-13), in others short and comparatively stout (PI. viii,
figs. 12-14), in the former case the joints are longer than wide, and
in the latter as wide, or even wider than long. The most im])or-
tant modification observed is in the mode of their serration. By
far the larger number of our species have the antennce serrate be-
ginning wdth the fourth joint (PI. viii, figs. 11, 12); in the others
the serration begins at the fifth joint (PI. viii, figs. 13, 14). There
may be at times a (juestion wdth those who study this character for
the first time and in some species it might be difficult to determine
to which series it should be referred, but whenever the fourth joint
resembles the fifth more nearly than it does the third, the species
belongs to the first series, but when the third and fourth joints are
similarly cylindrical then the species belongs to the second series.
NORTH AMERICAN COLEOPTERA.
279
Head. — The front may be flat, moderately convex, or very con-
vex. In the latter case the month seems more retracted and inferior,
as will be observed in the sjiecies from jmlchelhis to muticus, but va-
rying in degree, so that this character fails to be useful foi’ generic
separation. In nearly all the species the head has a median im-
])ressed line beginning at the occiput, but this varies both in extent
and depth, forming in several sj)ecies a deep frontal depression or
even concavity. The clypeus varies somewhat in form, but not to
the extent observed in Chrysobothris, so that no use has been made
of it in the table. Sexually the head varies in sculpture and coloi',
as will be found recorded, but the differences between the sexes are
not by any means as well marked as in Chrysobothris, or in the more
closely allied Anthaxia. Other characters of more resti-icted oc-
currence will be found under the species in which they occur.
Prothorax. — The usual thoracic characters based on color, sculp-
ture and the depressions require no S{)ecial comment. The carina of
the hind angles has nearly always been mentioned from the earliest
descriptions, and its presence or absence regarded as an infallible
sign of specific distinction. It remains now to be recorded that in a
number of species the presence or absence of the carina is often
purely sexual, the male being without it. This is well shown in a
series of acutipennis. In all cases the presence or absence of carina
must not be assumed to be of specific value, except when accompanied
by other characters.
The lateral marginal edge of the thorax assumes two forms when
viewed from the side, the sinuate and straight. The former is the
more usual, and is well illustrated by macer (PI. viii, fig. 9), while
the straight form is mostly seen in the cylindrical species, such as
lacndris, etc. (PI. viii, fig. 10).
Prosternum. — The prosternal lobe varies in length and form,
sometimes almost entirely concealing the mouth. Its anterior margin
may be broadly rounded as in cavatm (in which the mouth is nearly
concealed), truncate as in bllineatus, or emarginate, as is the more
usual occurrence. Various forms of emargination will be observed,
the most irregular being in difficilis, in which the notch is small, and
on each side there is a sinuation.
The tip or apex of prosternum is subject to great modification. In
many species the tip is continuous with the intercoxal portion and
enters the metasternum by a triangular notch, while in others the
tip is abruptly bent upwards and enters the metasternum concealed.
280
GEO. II. HORN, M. D.
This structure has been well described by Mr. Waterhouse. When
the tip of the prosternuni is closely applied to the metasternum, the
portion of the ape.x not concealed assumes various forms, being tri-
angular, rounded, truncate or dilated (see muticus and species near).
For convenience of expression in the analytical table, the visible free
portion has been assumed to be the tip, and is so spoken of in the
table.
SciTTEEEUM. — The two forms observed are charactei’ized by the
presence or absence of a transverse carina. This structure seems to
have been considered as invariable as the angular carina of tli,e
thorax, but in several of our species the carina may be distinctly
jiresent in some specimens and entirely absent in others.
Elytra. — In nearly all of our species the sides of the elytra are
slightly sinuate behind the humeri, and then more or less dilated
before finally narrowing to the aj)ex (PI. viii, fig. 7), but in many
others the elytra narrow from the luuneri to the apex almost without
sinuation as in difficilis (PI. viii, fig. 8). In the former case the sides
of the abdomen are much less visible from above than in the latter.
As a rule the elytra are narrower in the male. The disc is not often
costate and then only in the species of the tropical ty[ie, as in Couesii,
cavatns and macer, but in very many species there is on each elytron
a very vaguely indicated costa.
The surface sculpture is practically the same in type in all our
species, and is derived from a form described as imbricated, resem-
bling, when magnified, a series of pointed tiles, closely placed, in
which the points are somewhat elevated. The sculpture in s’ome
species might be described as closely mucronate.
The apices of the elytra are not, in any of our species, provided
with the curious prolongations and modifications seen in the tropical
forms. The tip is rarely very acute {nevadensis) , usually rounded.
The edge is usually serrulate, and in a few species entirely sim[)le
(jmdicus, etc.).
PvGiDiUM. — In very nearly all our species the pygidium is pro-
vided with a median smooth or elevated line, in many species forming
(piite a ridge, and in a good number the ridge is ])rolonged, forming
a spine sometimes emarginate at its apex {macer). The presence or
absence of the prolongation is one of the most constant of the struc-
tural characters, although specimens of rnficolUs are occasionally
seen without it. The pvgidium oi pulchellm is acute at tip, the carina
well marked, but not independently projecting.
NORTH AMERICAN COLEOPTERA.
281
Abdomen. — The principal modifications of the abdomen are due
to sexual pecnliarities of the male, which are sufficiently described
under the species in which they occur. Several pecnliarities have
been observed which are not sexual. In ventralis the middle of the
posterior edge of the second segment is free and prolonged slightly
over the next segment ; the same is observed in the third segment,
but in a less degree. The sides of the last ventral segment are nsnally
simple, but in a few species (obolinm, Wahinc/liami) the edge is dis-
tinctly serrulate. The apex of the segment is rounded or oval, ex-
cept in a few species (conciniins, acutipennis), in which it is truncate.
In iiiine of our species is the last ventral emarginate, as in many
European species.
Along the side of the abdomen there will be observed a well ele-
vated ridge, which is sometimes interrupted on the first or second
segments, usually more or less sinuous in front. Although variable
within certain limits it is not sufficiently so to warrant any use of it
in the grouping of species. This line divides the ventral segments,
so that the upper jiortion, usually sub-elytral, has been called, for
conveidence, the “vertical ])ortion of the segments;” it is often dif-
ferently clothed from the inferior part of the segment.
The suture between the first two segments is usually entirely ob-
literated, but in Walsinghami \s visilile at the sides; in some speci-
mens of acutipennis, and more rarely bilineatus, the suture is faintly
indicated. The pre.sence of this suture has affi)rded Mr. Waterhouse
the means of separating a small number from the mass of species in
Mexico.
Legs. — The legs in all the species are slender, and afford very few
characters useful in separation. In a good number sexual differences
have been observed in the tibiae, consisting of a short spine or mncro
at the inner apical angle of the anterior tibia and sometimes {otiosus,
etc., FI. viii, fig. 18) on all the tibiae of the male; the female tibiae
are simple in all the species. The tarsi vary, apparently, in length.
Apparently, because in estimating their length some comparison
must be made with adjacent parts, and it will be found in nearly
every case the tarsi bear the same relation in length to the tibia.
The claws vary greatly in form, affording nsefnl characters in
grouping the species, although the demarcation is not so sharply
defined as to render differences primarily useful.
In no case are the claws simple, or even approaching that condition.
Mr. Crotch remarked that while the claws of many European species
TR.VN.S. AM. ENT. SOC. XVIII.
(3(3)
SEPTEMBER, 1891.
282
GEO. H. HORN, M. D.
were bifid, they were not so in any American form that he had seen.
It seems to me that a careful homological study of the claws shows
that in all our species these members are either bifid, or of a modified
l)ifid form. While they are usually called cleft, there is no truly
cleft claw in any species. If we examine the species related to }W-
litus and those near torpidus, the claws will he found so nearly of the
true bifid type that they should he called so. Tracing the modifica-
tions of this form it will be observed that the inner member of the
bifid tip gradually shortens and broadens, while it preserves its lateral
position in relation to the other part, although becoming quite a
broad tooth.
It seems not to have been noticed that in the group above indicated
the claws are not only different in the two sexes, but, especially, in
the male, different on the three pairs of feet. This effectually pre-
vents anything but the most I’estricted use of the forms of the claws
in separating either groups of species or species themselves.
As the descriptions of the modifications of the claw would be an
unnecessary rei)etition at this time, the student is referred to the
remarks under each species.
At this time I desire to acknowledge the assistance received, with-
out which this essay would have fallen short of its present complete-
ness. The Museum of Comparative Zoology has permitted the free
use of the LeConte collection for conq)arison, without which the
names here used would have less certain value. The National Mu-
seum, through its Curator, Dr. C. V. Riley, has loaned its material,
which has in one case removed a doubt from my mind, and in several
others prevented the necessity of describing from uniques. The
cabinet of the American Entomological Society has ako been freely
used. To Messrs. Ulke, Liebeck, Seeber, Wenzel and Henshaw, I
am indebted for the free use of their material and the gift of speci-
mens. Finally, to Mr. Fred. Blanchard, of Low’ell, I am under
especial obligations for his many useful suggestions, and for his hav-
ing very kindly studied several difficult questions regai’ding the
of imus senes on the carefully collected material in his cabinet.
The meaning of the expressions used in the subsequent j>ages of
the essay having been sufficiently explained, the following table is
presented to enable the species to be, at least approximately, deter-
mined. The arrangement of the species by the sequence in the table
does not in all cases ajjproximate those having a superficial resem-
blance. The object of this study is to enable the determination of

the species and the minor detail of a cabinet arrangement can he
left to the judgment of those who possess a sufficient number to make
it desirable.

In order that there may be no misunderstanding, the species de-
scribed by Say have been thought worthy of S[)ecial reference, so
that some previous erroneous determinations may be corrected.
For convenience the species will he given in the order described,
and reference made to “ The com[)lete writings of Thos. Say on the
Entomology of North America,” edited by John L. LeConte, M.D.,
under the abbreviated title, ” edit. Lee.”

adopted, and in general use everywhere, it has been retained for the species.
As Say described both, and as one or the other must be a synonym, it seems
to matter but little which one is suppressed.
.4. (liflioilis Gory. — Form elongate, piceous, with a faint greenish or cupre-
ous surface lustre. Antennae piceous, slightly bronzed, reaching beyond the
middle of the thorax, serrate from the fourth joint; front flat, closely coarsely
punctate, obsoletely bituberculate and with short pubescence, occiput slightly
impressed. Thorax broader than long, slightly narrowed at base, sides slightly
arcuate, the marginal line from the side slightly sinuous, disc convex, a feeble

the middle, apices rounded and serrulate, basal fovea rather feeble, disc convex,
with faint costa, the surface punctate, but not close, becoming imbricate near the
apex; body beneath with more decided metallic lustre ; prosternal lobe rounded,
with an acute emargination at middle, the inter-coxal process broad, parallel and
obtuse at tip ; prosternal pleurm punctate and pubescent, meso- and metasternum
at sides more densely punctate and similarly j)ubescent, along the middle much
smoother; ventral segments along the middle sparsely punctate, first segment at
sides densely punctate, .strigose; the second, third and fourth segments with a
more densely punctate spot conspicuously pube.scent, the vertical portions of all

GEO. H. HORN, M. D.
Male. — Front flatter, more densely, but more finely pnncfate,
nsually greenish in color; prosternnm densely punctate along the
middle with (piite fine, sub-erect, silken pul)escence ; metasternum
convex ; ventral segments similar in the sexes, not impressed.
Female. — Front more coarsely punctate, color more or less cupre-
ous; prosternum rather coarsely, not closely punctate, not pubescent.
Variations. — The only variations noted are those of size and color,
which do not change the aspect of the species in any great degree.
Of the habits of this species nothing has been recorded. This is
one of the larger species in our fauna, although several exceed it in
size.
The claws are cleft, and with the lower portion incurved, as re-
(piired in the group, although less incurved than usual, so that the
])oints are (piite distant. This divergence from the tyjie of the group
is the more marked in the male, the claws of the other sex being
nearly contiguous.
Hab. — Occurs in the Mississippi Valley from IMissouri to Texas.
A. 11. sp. — Form robust, obscure seneous, opaque. Autenuae short,
serrate from the fourth joint, slightly cupreous; head densely coarsely punctate,
slightly strigose on the occiput, lougitudiiially impressed from the occiput to the
clypeus. Thorax broader tlian long, slightly narrowed in front, sides straight,
arcuate near the front, lateral line not sinuous, base slightly broader than the
humeri, a moderately deep impression behind the front angles, which is entirely
lateral, median line rather broadly and deeply concave, hind angles not carinate
% , obsoletely carinate 9 ; surface coarsely, closely and irregularly strigose, the
intervals between the ridges punctate; elytra broadest at base, scarcely dilated
behind the middle, apices separately rounded, .scarcely serrulate, basal depres-
sions almost obliterated, disc rather flat, vaguely concave along the middle of
each side ; surface densely granulate, strigose ; body beneath similar in color, but
very obtuse, intercoxal process rather broad, parallel and very obtuse at apex,
propleiiraj coarsely punctate, slightly strigose; abdomen finely punctate at mid-
dle, more densely and roughly at the sides, the lateral marginal line entirely
obliterated on the first two segments; x)ygidium jninctate, indistinctly carinate;
claws similar on all the feet. Length .36 inch. ; 9 mm.
Male. — Prosternnm densely punctate and rugulose sparsely, finely
pubescent. Ventral segments not impressed.
Female. — Unknown.
The two specimens before me show no variation.
The entire obliteration of the marginal line on the first two ventral
segments is a character not observed elsewhere in our species.
In form and general appearance this species resembles obolinns,
which is also remarkable in having the marginal line of the abdomen
faintly indicated on the first segment.
llab. — Texas, ])robably near the lower Rio Grande.

the sides of the sterna cupreous; prosternum rather broad between the coxae,
parallel, the apex obtuse, the lobe short and obtuse, propleurte coarsely punctate,
slightly strigose; metasternum coarsely punctate at middle, becoming strigose at
the sides; abdomen rather coarsely and closely punctate, becoming strigose on
the sides of the first two segments, the vertical portion of the segments sparsely
golden pubescent their entire length ; pygidium coarsely punctate, indistinctly
carinate ; claws similar on all the feet in both .sexes. Length .40 — .,50 inch. ; 10 —

male.
Variations:. — So few specimens have been collected that hut little
variation has been observed. The thorax is entirely cupreous, the
median line more golden, and on each side of this is a longitudinal
space of darker color, which varies in its intensity of color and
extent.
Of its habits nothing is known.

.V. riitirollis Fab. — Black, or blue-black; head and thorax usually bright
cupreous. Autennse black, serrate from the fourth joint, the serrate joints as

rapidly liner toward apex, where the segment is finely or sparsely punctate;
pygidium carinate, the carina projecting in a spine; the vertical portion of the
ventral segments punctate and sparsely pubescent; claws similar on all the feet
in both sexes. Length .22 — .28 inch.; 5. .5— 7 mm.
Male. — Front more deeply impressed, less coarsely jninctate ; elytra
not wider at the post-median expansion tlian at the humeri ; proster-
num more coarsely punctate, metasternum slightly concave ; first
ventral segment concave along the middle, the second segment rather

Variations. — The normal and most common form has the head and
thorax of bright cupreous color, the elytra black, .sometimes with
a slight tinge of blue. The color of the head and thorax is, at times,
quite brassy shading gradually to green. Specimens more rarely
occur with these j)arts quite black, although with more gloss than
the elytra. In all other characters excepting size, the species is re-
markably constant.
Habits. — The larva of this insect feeds in the stems of Blackberry
and Raspberry, emerging in the early Summer. An excellent article
illustrating the injuries done, together with a figure of the larva, will
be found in “ Insects Injurious to Fruits,” by Wm. Saunders (J. B.
Lippincott Company).
Hab. — Occurs from Canada and the New England States south-
ward to Virginia and westward to Missouri.
A. lateralis Say. — Form of ruficollis. Head and thorax cuiireous; elytra
black, with slight feneous lustre. Anteniire piceous, slightly bronzed, scarcely
attaining the middle of the thorax, serrate from the fourth joint ; head imjiressed
from the occiput to the clypeus, less deeply than in ruficollis. entire head rather

acute; pro- and nietapleurae closely punctate, not pubescent; abdomen moder-
ately closely punctate, more finely along the middle, niore coarsely and roughly
at the side of the first segment ; pygidium coarsely punctate, carinate, the carina
ju'ojecting at tip; claws similar on all the feet in both sexes, the lower portion
of the cleft more nearly contiguous in the female. Length .25 — .28 inch.; 6.25

Male. — Pmsteriumi coarsely, not closely punctate, without jtubes-
cence ; first ventral segment slightly depressed along the middle,
second with a deep, smooth groove extending more than half its
length.
Feiaale. — Prosternum less punctate, smoother ; first two ventral
segments simple.
Four specimens have afforded the above description. Another
specimen in Mr. Ulke’s collection is of somewhat larger size, and
with more even thorax, seems to belong here, although the discovery
of the male may prove it distinct.
This species greatly resembles ruficolUs, but may be distinguished
by the less deeply impressed head and the presence of either a slight
evidence, or a distinct carina, in the hind angles of the thorax. The
sexual characters of the two are practically identical ; several other
species have also some resemblance, but these have no pygidial spine.
HabiU — The wood in which the larva lives is not known, but the
imago has been taken on foliage of Poplar sprouts (Blanch. Ent.
Am. V, p. o2, under the name auxins).

Mexico (Ulke), Illinois (Dury), Missouri (Say).
.4. otioKiis Say. — Form slender, sometimes linear in the male, stouter in the
female, usually dull greenish, sometimes slightly cupreous. Antennae usually
bluish, extending nearly to the hind angles of the thorax, a little shorter in the
female, joints all longer than wide, serrate from the fourth joint; head viewed
from above slightly convex, with a very slight occipital impression, front rather
flat, coarsely and closely punctate, occiput faintly strigose. Thorax a little wider
than long, slightly narrowed at base in the male, sides feebly arcuate, but more
distinctly in the female, lateral edge straight , or feebly sinuous hind an-
gles obtusely or indistinctly carinate , or usually with a well defined carina 9 ,
disc convex, an oblique lateral depression and on the median line two depres-
sions, the posterior the larger; surface transversely strigose, with fine punctures
between; scutellum transversely carinate; elytra slightly sinuate behind the
middle, entii-ely concealing the abdomen from above, apices separately rounded,
finely serrulate, elytra with a vague costa from the humeri behind the middle,
between which the elytra are slightly flattened, and behind the middle the su-

tiiral edge is slightly elevated ; basal depressions distinct; surface with a densely
imbricate sculpture; body beneath usually bluish, more shining than above;
prosternal lobe obtuse, vaguely emarginate, the intercoxal process gradually nar-
rowed and acute at tip, propleui'se scabrous or subgranulate ; metasternum coarsely
punctate ; abdomen punctate, more sparsely along the middle, quite coarsely along
the side, the first segment quite rough ; pygidium coarsely punctate, indistinctly
carinate; tarsi slender, the first joint of the hind tarsi nearly half as long as
thetibiic; (daws similar on all the feet in both sexes. Length .16 — .22 inch.;
4 — 5.5 mm.
J/a/e. — Form more slender, sometimes tilmost linear; front flatter,
more densely punctured ; hind angles of thorax less distinctly cari-
nate ; prosternum densely, finely punctate, finely pubescent, the pu-
bescence usually extending along the median line of the body to the
end of the second ventral segment ; first two ventral segments vaguely
sulcate on the median line. Inner apical angle of all the tihiie
spiniform and incurved.
Female. — Form stouter, usually with more evident leneous surface
lustre ; front slightly more convex, more coarsely, but less closely
punctate, the occipital impression extending slightly downward ; hind
angles of thorax (piite distinctly carinate ; prosternum much more
sparsely |)unctate, not hairy ; first two ventral .segments not im-
]>ressed and with smoother scul])ture.
Variations. — The most striking structural variation is the hind
angles of the thorax. The sexual variation has already been re-
corded, but s])ecimens are before me as completely deprived of carina
as any species in our fauna, not only males but females also. The
smaller and less developed males have the ventral sexual characters
less pronounced, so that the pubescence along the median line be-
comes less distinct and the sulcus of the first two ventral segments
almost entirely disappears. The color variations are not great, the
males, however, are in a great part dull bluish, while the females are
slightly greenish or cupreous.
As this is a common and well known species, much space has been
given to its description as a means of comparison for other species.
Say’s A. geminaius is undoubtedly the female (T this, suhsecpiently
described by him as otiosus. The former name has priority by sev-
eral years, but the latter name is retained from its having acquired
general acceptance, and from the fact that both belong to the same
author and no injustice is done. This is clearly one of those cases
in which the law of priority should yield to that of convenience.
Habits. — Feeding on Oak shrubs (Blanch. Ent. Am. v, p. 32). I
think it has been reared from Hickory twigs by Dr. LeConte.

A. defectii!^ Lee. — Form and coloi-s of oiiosus. Autennie attaining tlie mid-
dle of the thorax, the joints scarcely longer than wide, serrate from the fourth
joint; head slightly convex, with scarcely a trace of occipital impression, front
and occiput punctate. Thorax wider than long, not) narrower at base, sides
arcuate from apex to base, hind angles obsoletely carinate in both sexes, lateral
margin very nearly straight, disc convex, a vague oblique depression at the sides,
two dei)ressions on the median line, but feebler than in otiosus : surface trans-
versely strigose, the grooves punctate, more distinctly than in otiosus ; scutellum
transversely carinate ; elytra sinuate behind the humeri with the post-median
dilatation concealing the abdomen, apices rounded, finely serrulate, disc with
scarcely a trace of costa, the sutural border elevated behind the middle, basal
depressions feeble ; surface imbricately sculptured, but smoother near apex ; body
beneath more shining, dull bluish green ; prosternal lobe obtuse, vaguely emar-
ginate, the intercoxal process gradually narrowed and acute at tip, propleura?
moderately closely punctate; metasternum not closely imbricate. Abdomen
sparsely punctate along the middle, a little more closely at the sides; pygidiuin
coarsely sparsely punctate, feebly carinate; tarsi slender, as in otiosus; claws
similar on all the feet. Length .16— .18 inch.; 4 — 4.5 mm.
Male. — Front more opaque and finely punctate; prosternuni
coarsely, not clo.sely punctate, rather opaque. First two ventral
segments faintly grooved, but not pubescent ; last ventral truncate,
with a marginal fringe of hairs, curved and directed downward.
Inner apical angle of all the tibiae s])iniform, slightly incurved.
Female. — Front more shining and more evidently punctate ; pros-
ternum more shining. First two ventrals not grooved, last ventral
oval at tip, not fimbriate.
Of the habits of this species I have no information. The only
variations observed are those of color as in otiosus, the females rather
more brassy.
There can be very little doubt that this species was originally in-
stituted to contain all the small specimens of otio.ms in which the
Carina of the hind angles of the thorax is nearly or (piite Avanting.
An examination of the series showed, however, that, abstracting the
true otiosus, there remained specimens, one of which bore the type
label, which clearly indicated a distinct species. They were, how-
ever, females. A few days later Mr. Blanchard gave me a male,
which was clearly a mate for the type. As might be inferred from
the preceding i-emarks, the sjiecies very closely resembles small or
starved specimens of otiosus. There need be no ditficulty, whatever,
in separating the males from any Agrilus in our fauna, but the fe-
males are more difficult. It will be observed, however, that in the
294
GEO. H. HORN, M. D.
present species the median line of the abdomen is very smooth, almost
without punctures. In fact, the entire abdomen is less sculptured
than usual. When once a male is obtained there will be no great
difficulty in separating the female from otiosiis.
It is evident that LeConte had before him a male of this species
which he mistook for the male of laeu.st7'i.s, but I failed to find the
specimen at present associated with that species, and discovered that
it had been removed and placed with the present species either by
himself, or later by Crotch.

A. criiiicoriiis n. sp.--Forra slender, as in otiosus, color olive-bronze with
a slight bluish tinge at the sides, slightly shining. Antennse slender, bluish,
passing the hind angles of the thorax, joints all longer than wide, serrate from
the fourth joint, fimbriate on the posterior side with comparatively long, sparsely
placed hairs; front rather fiat, a slight occipital depression, subopaque, sparsely
punctate, occiput faintly strigose. Thorax wider than long, slightly narrowed
at base, sides arcuate, margin slightly sinuous, hind angles not at all or very
feebly carinate, disc moderately convex, a deep oblique lateral and two me<lian
depressions as in otiosus; surface indistinctly transver.sely strigose on the disc
with intervening punctures, at .sides in front punctate; scutellum transversely

giuate, the intercoxal pro<'ess gradually narrowed, acute at tip, propleurfe opaque,

num rather flat, opaque, sparsely punctate, not pubescent ; first two

While closely related to otiosus, the male gives evidence that the
species is quite distinct. Females have not, with certainty, been
separated, consequently it is not po.ssible to assert that the pilosity
of the anteniue is peculiar to the male.* The anteniue are certainly
longer and more slender than any species in the vicinity of otiosus.

the thorax; head slightly convex, a very feeble occipital impression, more dis-
tinct in the female, front densely punctate, occiput slightly strigose. Thorax
wider than long, slightty narrowed at base, sides in front arcuate, a slight sinua-
tion posteriorly, lateral margin sinuate, hind angles with a sharply defined carina
in both sexes, disc convex ; an oblique, but not deep impression at the sides, two
depressions on the median line as in otiosus, but much less distinct; surface not
coarsely transversely strigose, with fine punctures on the intervals; scutellum
transversely carinate ; elytra slightly sinuate behind the humeri, then somewhat
dilated, concealing the abdomen, apices rather obtusely rounded, finely serrulate,
disc with a vague costa on each side, the intervening space rather flat, sutural
margin elevated behind the middle, basal depressions shallow, surface closely
imbricately sculptured; body beneath more .shining than above ; prosternal lobe
obtuse, broadly and rather deeply emarginate, the intercoxal process gradually
narrowed, acute »t tip, propleurse closely punctate ; metasternum at sides densely
submuricately sculptured. Abdomen closely punctate, and on the first two seg-
ments denser and submuricate ; pygidium sparsely punctate, indistinctly carinate ;
hind tarsi slender, as long as the tibiae, the first joint as long as the four fol-
lowing ; claws similar on all the feet in both sexes. Length .24 inch. ; 6 mm.
Male. — Front flatter, more opaque and more densely punctured,
usually greenish ; prosternum with a space in front densely covered
with short erect pubescence, the intercoxal jirocess smoother, with a
median longitudinal elevation. First two ventral segments flattened,
or vaguely concave along the median line, not pubescent. Inner
apical angle of the front and middle tibiae spiniform and incurved,
posterior tibiae simple.
Female. — Front more convex, more coarsely and less densely jiunc-
tate, usually brassy ; prosternum not hairy, the intercoxal process
flat. Abdomen not impressed, and less roughly sculptured.
Of the habits of this species I have no information. The four
specimens examined show no variation beyond that given in the
detailed description.
It is highly probable that this species is mixed with otiosus in those
collections possessing it. In fact, so great is the superficial resem-
blance that with ordinary compaiTson they could not be separated.
The males are, however, easily separated by the pubescent area at
the front of the prosternum. The median subcariniform elevation
of the intercoxal process bifurcates about the middle of the sternum
like a broad letter Y, and in the bifurcation behind the emargina-
tion of the lobe the jnibescent area is placed. The females, if I have
correctly separated them, are not so easily distinguished from the
larger females of otiosus, Imt I observe that in both sexes the elytra

are much more obtuse at apex than in that species, and the sutural
angle rather better defined.
llab. — Canada, New York and Illinois. The two supposed females
are from Mt. Tom and Tyngshoro, Mass., and were collected by Mr.
Blanchard, wlio separated them as not being fully in accord with
normal females of otiosvs.
\. aroiiufiis Say. — Moderately elongate, not more robust than ruficoUis ;

passing the middle of the thorax, seri-ate from the fourth joint ; front moderately
impressed from the occiput nearly to the base of the clypeus; surface coarsely,
moderately closely i)unctate, somewhat strigose on the occiput. Thorax one-
fourth wider than long, not narrowed at base: sides regularly arcuate, the mar-
gin slightly sinuous, disc convex, the median line with an anterior and posterior

less defined; prosternum closely itunctate and slightly pubescent;
metasternum longitudinally impressed ; first ventral segment slightly
flattened, not hairy ; anterior and middle tibite with a slight mucro
at the inner apex, the posterior simple.
Female. — Head more convex, the frontal impression dee|)er and
sometimes bifurcate near the clypeus, color copj^ery or brassy ; pro-
sternum more shining, less closely punctate, not hairy ; metasternum
feebly impre.ssed ; abdomen simple ; tibio3 not mucronate.
Variations. — 'fhe variations of this species are so pronounced that,
with a limited series, three species might be indicated, as has in fact
been done. The.se are as follows :
Var. torquatus Lee. — Head and thorax brassy, or slightly coppery
or greenish, elytra dark olivaceous.
This form is widely distributed : Massachusetts, ^Michigan, Mon-
tana, Illinois, Kansas, Kentucky, Pennsylvania. Thei'e is often a
great resemldance between some of the smaller females of this and
NORTH AMERICAN COEEOl’TERA.

the larger females of oUo.'ius, and at present I am unable to give any
positive means of separating them, except the experience gained in
handling large numbers of specimens.
Yar. f if If/ ens Lee. — A little more shining than normal.
Var. coryli Horn. — Color uniformly bright brassy.
This form occurs in Massachusetts, Illinois, Missouri, Florida.
Var. obliquus Lee. — Color uniformly coppery.
The type of this form, as remarked by Crotch, is founded on a large
female ; in fact, all the specimens I have seen are of that sex. These
resemble some of the forms of poliius, but the structure of the claws
will separate them.
Habitft. — The only information possessed of the habits of this spe-
cies concerns the var. coryli, which lives on the Hazel (Corylus) ac-
cording to Mr. Blanchard (Ent. Am. v, p. 32).
Hub. — Massachusetts to South Carolina, westward to Kansas and
Montana.
A. ciiprieolliN Gory.— Form o? riificollis ; I)lack, siihopaque ; head and tho-
rax brassy or cupreous, as in ruficoUis. Antenufe black, slightly bronzed, .scarcely
reaching the middle of the thorax, serrate from the fourth joint, joints 4-10 as

dian. rather sharp impression posteriorly, broadly transversely impre.ssed in front,
at sides a deep oblique impression almost reaching the dorsum, surface coarsely
transversely strigose. without punctures; scutellum transversely carinate ; elytra
very feebly sinuate behind the humeri and with a feeble posterior broadening,
the abdomen concealed, apices separately rounded, serrulate, disc slightly flat-
tened with very feeble trace of costa, the sutin-al edge slightly elevated behind
the middle, basal depressions not deep; surface closely finely granulate; body

nate; claws similar on all feet. Length .20 inch. ; 5 mm.
Male. — Prostenmm opaque, sparsely punctate, with short pubes-
cence, ventral segments not impressed nor flattened. IMetasternum
longitudinally impresed. Anterior tibite with an extremely feeble
incurved mucro at tip, middle and hind tibite siinjile.

So closely does this species resemble raficollis, that at first glance
it might readily be supposed to belong to that species. They are

easily separable by the fact that tbe former lias a well marked j)ro-
jecting Carina, while this has not. The occipital impression gives
the appearance from above of a bilobed head, and the impression
does not extend downward on the front, while in rnficollis the occiput
is rather concave and the impression reaches the clypeus.
Occurs in Florida at St. Augustine.
•\. aiij^elicus ii. sp. — Form rather robust, as in muticus ; color brassy, mod-
erately shining. AuteuiiEe piceoiis, bronzed, not reaching the middle of the
thora.x, serrate from the fourth joint. Head slightly convex, a finely impressed
line from the occiput to the clypeus, surface finely, not closely strigose, sparsely
punctate, clypeus much broader at base than long at middle. Tliorax broader
long, base and apex equal, sides arcuate in front, sinuate behind the middle,
hind angles rectangular with a short, acute, straight carina, disc convex, a vague
median depression, another broad depression at the sides; surface transversely,
not coarsely strigose with intermediate sparse punctures; scutellum not trans-
versely carinate ; elytra distinctly sinuate behind the humeri and broader bebind
the middle, the apices separately rounded and very feebly serrulate ; disc convex,
without trace of costae, the basal depressions moderate, surface rather finely im-
bricately sculptured ; body beneath more shining than above; prosternal lobe
obtuse, broadly but feebly emarginate, the intercoxal process gradually narrow-
ing, the apex acute, propleurae with reticulate sculpture; metasternum coarsely
punctate, reticulate. Abdomen finely punctate-strigose at middle, a little more
coarsely at the sides, the first segment but little more rugose; pygidium coarsely
punctate, feebly carinate ; claws similar on all the feet. Length .25inch.: 6.5 mm.
The only specimens seen are females, and sliow no secondary sexual
characters. The lower appendage of the claws is less incurved than
usual, reaching the form seen in difficilis. Should the form of claws
induce one to place it elsewhere, it would be placed in the series near
muticus, from any of which it will be known by the acute prosternum.
One specimen collected by Mr. D. W. Coquillett near Los Angeles ;

A. iiiacer Lee. — Elongate, cupreo-aeneous, feebly shining. Antennae piceous,
with brassy lustre, nearly reaching the middle of the thorax, serrate from the
fourth joint; front flat, or slightly concave; occiput feebly impressed, the line
extending to the middle of the front, surface rather uneven, densely coarsely
punctate, slightly strigose on the occiput, a well marked transverse ridge at the
base of the clypeus. Thorax nearly a third wider than long, very slightly nar-
rowed at base, sides feebly arcuate, margin slightly sinuate, hind angles rectan-
gular, the carina well marked and directed internally, disc convex, a vague me-
dian depression near the base, lateral depression broad, but not deep ; surface not
deeply transversely strigose, punctate between the strig*, near the sides and
front angles more densely strigoso-punctate ; elytra narrowed from the base with
a very feeble post-median broadening, the ajiices rounded, rather strongly ser-
rate, disc with a well marked costa extending from the humeri nearly to apex,
the interval quite flat, the sutural border elevated slightly from apex, two-

thirds to base, basal depressions shallow, surface punctate-granulate, rather
densely between the costie, more sparsely at the sides; body beneath similar in
color; prosternal lobe broadly emarginate, the interc.oxal process broad with
parallel sides, very abruptly narrowed at the apex, where it enters the meta-
sternum; propleurie closely punctate, finely fulvo-pubescent ; metasternum at
sides very densely punctured and subopaque, finely pubescent. Abdomen
densely punctured at the sides, especially in front, rather sparsely along the
median line ; last segment very obtuse, subtruncate, the vertical portion of the
segments rather densely fulvo-pubescent; pygidium carinate, the carina pro-
jecting and emarginate at tip ; claws divaricate, broadly toothed at base. Length
.35 — .58 inch. ; 9 —15 mm.
Male. — Front slightly concave ; scutelluni scarcely visibly carinate.
Prosternntn densely punctate and slightly pubescent along the mid-
dle. Ventral segments simple; anterior tibite feebly mucronate.
Female. — Front flat, but irregular; scutellum distinctly carinate ;
prosternum not densely punctate nor hairy ; tibiae simple.
No variation worthy of note has been observed in this species.
In the original description the scutellum is said to be not carinate,
but this proves in this instance to be merely a sexual peculiarity, as
it is quite certain that Dr. LeConte had a male before him.
No difficulty need be experienced in recognizing this species, as it
is one of but few having a well defined elytral costa, and for this
reason, especially, seems rather out of place among our species.
Hah. — Texas, at Eagle Pass, and other localities in the southwestern
jiortion of the State.
-4. vittatocollis Eand. — Form generally resembling a ]nr^e rujicoHis ; head
and thorax coppery, subopaque, elytra black, opaque. Anteniipe passing the
middle of the thorax, serrate from the fourth joint, piceons, faintly bronzed ;
front slightly concave, the occiput more deeply impressed, the median impressed
line extending to the base of the clypeus, surface rather closely strigose and
punctate, clothed with golden-yellow pubescence, except near the upper half of
the eye. Thorax fully one-third wider than long, sides rather strongly arcuate,
the margin sinuate, disc convex, with a median shallow imj)ression extending
from base nearly to apex, lateral depressions vague, hind angles not cai-inate.
surface closely strigose, the strigte. oblique in front, transverse near the base, a
median band of golden pubescence extending from the basal to the apical margin,
a l)roader band of similar pubescence adjacent to the lateral margin, the hind
angle, however, not pubescent; scutellum transversely carinate; elytra distinctly
sinuate behind the humeri, broadened behind the middle, nearly concealing the
abdomen, apices rounded, serrulate ; d i.sc slightly flattened, without trace of costse ;
the sutural edge slightly elevated at apical third, basal fovete moderate; surface
densely granulate and opaque; body beneath black, slightly seneous, with very
sparse, fine golden pubescence ; prosternal lobe obtusely truncate, the intercoxal
process broad, very little narrowed, except at apex, where the narrowing is ab-
rupt, at which point the sides are slightly bent downward forming a tooth ; the
surface, with the propleurte, closely punctate; metasternum at sides densely

puiictiite iuul strigose. Abdomen finely punctate, sparsely along the median line,
more densely at the sides, especially on the first two segments, which ai-e also
slightly strigose, the vertical portion of the segments densely clothed with golden
])iihescence ; last segment obtuse at tip; pygidium coarsely punctate, rather
strongly carinate, the carina projecting and truncate at tip ; claws dissimilar in
the sexes. Length .31 — .37 inch.; 8 — 9.5 mm.
Male. — Prostennmi densely jtunctured and opaque, not pnltescent.
First ventral segment slightly flattened at tniddle and rugulose, the
second with a very feeble longitudinal depression ; tibiae of all three
pairs distinctly inucronate at the inner apical angle ; claws of front
feet almost truly bifid, middle feet less so, posterior feet nearly toothed.
Female. — Prosternum less densely punctate and more shining.
Ventral segments not impressed ; tibiae not inucronate at tip ; claws
rather broadly toothed on all three jiairs of tarsi.
Among the numerous specimens examined no variation worthy of
mention lias been observed. Jiesemhles fuscipennis, but the color of
the thorax of that species is due to varying color of the surfoce, and
not to the presence of pubescence, as in the present species.
Hab. — Massachusetts, westward to Illinois. A specimen ( 9 ) in
my cabinet from Nevada is at present not sejiarable, but the male
may show it to be distinct when discovered.
.4. audax n. .sp.
The species for which this name is proposed so closely resembles
vittatocullis, that it seems unnecessary to repeat the description, only
the points of diflerence will be given.
Thorax similar iu color, but rather more evidently transversely strigose, the
median line of golden pubescence does not reach the apical margin, the lateral
pubescent area is separated from the margin by a naked edge, hut the pubes-
cence extends to the hind angles; body beneath more brassy, the propleurae,
mesopleurie, metapleurai and outer half of coxal plate with golden pubescence.
Length .35— .40 inch. ; 9 — 10 mm.
Male. — Prosternum closely punctate, not pubescent, the intercoxal
process gradually narrowed without dentiform reflexion of the edge.
First ventral segment slightly flattened at middle, the second with a
rather deep smooth groove, which is wider in front, extending three-
fourths to the posterior edge of the segment; anterior and middle
tibirn feebly inucronate, the posterior simple ; claws nearly as in
vittatocollis.
Female. — Prosternum less closely and deeply punctate. Ventral
segments simple ; tibiie not inucronate ; claws as in vittatocollis.
This species presents the closest resemblance that it seems possible

for one species to have to another. The males are abundantly dis-
tinct by the ventral charactei’s, but both sexes can be separated from
vittatocollis by the hairy jdeuras and coxal plates.
Hab. — Texas.
A. biliiiesitii!^ Weber. — Black, with sometimes a slightly greenish tinge,
opaque; sides of thorax clothed with yellow pubescence, and a vitta of same
from the humeri three-fourths to the tip of the elytra. Antennae slightly aene-
ous, extending beyond the middle of the thorax, serrate from the fourth joint;
front slightly convex, densely coarsely punctured, occiput impressed, the line
extending to the middle of the front. Thorax one-third wider than long, dis-
tinctly narrower at base, sides nearly straight anteriorly, sinuate near the hind
angles, which are sharply rectangular and not carinate, margin sinuous; disc
convex, a very vague median depression, the lateral oblique impression short;
surface rather finely transver-sely strigoso-punctate, the sides broadly clothed
with golden, rarely whitish pubescence ; scutellum transversely carinate; elytra
sinuate behind the humeri, broadened behind the middle, apices rounded, serru-
late ; di.sc flattened, the basal depressions moderate, sutural edge slightly elevated
at apical third, surface densely granulate and subopaque, with a vitta of yellow
or whitish hairs extending from the basal depression three-fourths to apex ; body
beneath more shining than above and more greenish ; prosternal lobe truncate,
intercoxal process rather broad, gradually narrowed to apex, propleurse granulate,
sparsely pubescent ; meso- and metapleur® and outerside of coxal plates rather
densely pubescent. Abdomen finely and sparsely punctate along the middle and
more densely and coarsely at the sides, the first segment rougher and strigose,
the vertical portions of the segments densely pubescent; pygidium coarsely
punctate, with a strong median carina, which projects at apex ; claws dissimilar
in the sexes. Length .22— .37 inch. ; 5.5 — 9.5 mm.
Male. — Head more or less green, more densely punctate and opaque.
Prosternum densely punctate and subopaque, esjtecially between the
coxte, not pubescent. First ventral segment slightly flattened at
middle, the second with a deep smooth groove ; anterior tibite slightlv
mucronate at apex, the others sinq)le ; anterior and middle claws
almost truly bifid, the posterior claws with a slender, acute tooth.
Female. — Head more convex, less densely punctured, more shining,
with lirassy or cuj)reous lustre. Prosternum more shining, less densely
punctured. Ventral segments simple; tibiie not mucronate ; claws
with a slender acute tooth on all the feet.
Variations. — The hair forming the lateral space of the thorax and
the vittie on the elytra is usually golden-yellow in color, but speci-
mens often occur with hair quite white with intermediate shades.
jNIore rarely specimens occur without any pubescent markings above,
the absence of hair not being due to abrasion, as might be suspected,
but seems to be the result of starved development, as all the speci-
mens seen are of the smallest size.

.4. gran 111 at us Say. — Form rather slender, color bra.ssy bronze, each ely-
tron with three indistinct pubescent spots — basal, median and ante-apical, the
first often wanting. Antennte slender, nearly reaching the hind angles of the
thorax, serrate from the fourth joint, slightly greenish ; front rather flat, occiput
with a linear impression extending to the middle of the front; surface coarsely
closely punctate, occiput slightly strigose. Thorax wider than long, scarcely
narrowed at base, sides regularly arcuate, lateral margin faintly sinuous, disc
convex with three depressions, the one larger in front of scutellum, the two
others in front on each side of middle less distinct, or even absent, the lateral
oblique inqn-ession well marked, hind angles with a well defined, arcuate carina;
surface transversely strigose, punctate in front; scutellum transversely carinate ;
elytra feebly sinuate behind the humeri, slightly broadened behind the middle,
apices acute, serrulate; disc slightly flattened at middle, the sutural margin
elevated behind the middle, basal foveas moderate, surface rather coarsely im-
bricate; body beneath darker than above ; prosternal lobe emarginate, the inter-
coxal process rather broad, parallel, acute at tip, the propleurse with the entire
side of body densely clothed with yellowish pubescence. Abdomen not very
closely punctate, the sides of each segment with a more densely punctured spot
clothed with pubescence, the vertical portion of the segments, except the second,
densely imbesceut; pygidium coarsely punctate, with a strong median carina,
which projects at tip; claws dissimilar in the sexes. Length .30 — .35 inch.;
7. .5 — 9 mm.
Male. — Front somewhat greenisli. Prostermim quite densely
punctured between tlie coxte, more sparsely in front; first ventral
segment longitudinally impressed with a smooth median line, second
segment more deeply impressed, the impression smooth and extending
nearly to the suture; anterior and middle tihiie feebly nuicronate,
the posterior simple ; anterior and middle claws almost bifid, being
cleft at the tip, posterior claws broadly toothed.
Female. — Front cupreous. Prosternuin coarsely jiunctured be-
tween the coxie, much smoother in front Ventral segments simple ;
tibim sinqile; claws broadly, but acutely toothed on all the feet.
Variations. — In all well preserved specimens there will be obsei'ved
a line of pubescence extending from the front angles of the thorax
to the base, passing inside of the carina. The pubescent spots of the
elytra are at most faint, and are easily removed by abrasion, but their
position is always indicated by a small and more densely punctured
area. The three discal impressions of the thorax are variable. The

position is always distinct, but the two in front may escape observa-
tion.
Of the habits of this insect nothing is certainly known. Care
must be taken not to confound small specimens of this with ohlongo-
guttatm (mterruptus) or fallax, but neither of the.se has the pygidial
spine.
It is quite clear that this is the species Say had before him from
his remarks in the original description, and a subsequent note (vide
edit. Lee. ii, pp. 104 and 596). LeConte, in his “ Revision,” p. 245,
admits both granulatus and quadriguttatus, but it is very clear that
he has used the female as his type of the former and a male for the
latter.
Hub. — New England States westward to IMissouri.
iievadeiisis n. sp. — Form elongate, elytra very acute at ape.v, piceous.

rately acute and somewhat prolonged, serrulate, disc slightly flattened at middle,
a vague costa on each side and three depressions, which are slightly pubescent;
basal, median and one-third from apex, surface vaguely not closely imbricate,
less closely than in cavatus ; prosternum closely punctate, the lobe distinctly
emarginate, intercoxal process gradually narrowed, acute at tip, propleurse closely
punctate, scabrous, sparsely pubescent; metasternum at middle comparatively

smooth abdomen without conspicuous jnibescence.
Hah. — Western Nevada (Morrison).
A. iii v('i vditri^ n. sp. — Form rather more slender than politus ; color
bright coppery, with the thorax slightly brassy, varying to olivaceo cupreous.
Antenna? ieneous, attaining the middle of the thorax, serrate from the fourth
joint. Head feebly convex, a slight median impressed line from the occiput to
the middle of the front, the latter densely punctate, occiput slightly strigose.
Thorax one-third wider than long, sides regularly arcuate, lateral margin slightly
sinuate, hind angles with a strong, arcuate carina, disc convex, with a vague
median depression composed of an anterior and a posterior depression, lateral
dej)ression feel>le; surface transversely strigose, with punctures between the
strigse; in some specimens the striga? are very feehle; scutellum transversely
carinate; elytra sinuate behind the humeri, slightly broadened behind the mid-
dle, apices separately rounded, finely serrulate, disc slightly flattened at middle
with an extremely vague costa; surface with imbricate sculpture, less close and
more shining than in politus, with three indistinct pubescent spots, often merely
indicated by a slightly denser punctuation, these spots placed as in nevadensis ;
prosternum densely punctured, the lobe acutely emarginate at middle, the inter-
coxal proce.ss i)arallel, acute at tip, propleurse densely punctured with consiiicuous
whitish pubescence; metasternum at sides densely |ninctate and transversely
sti’igose, pubescent as in the propleurpe. Abdomen sparsely punctate at middle,
more densely at the sides and finely strigose, especially on the first two segments,
vertical portions of the segments densely white jiubescent; pygidium coarsely
punctured with a strong median carina, projecting at apex. Length .25 — .37
inch. ; 6.5 — 9.5 mm.
Male. — Front slightly flatter; tibise not distinctly inncronate;
claws cleft one-third from apex, forming an achte tooth ; first ventral
segment flattened at middle, the second with a slightly depressed,
smooth space at anterior half of middle.
Female. — Front slightly convex ; tibite not inncronate; claws cleft
at middle, forming an acute tooth. Ventral segments convex at
middle, the first much smoother than on the male.
VariatioiU. — The color variation has been referred to. In many
specimens there is on each side of the median line, nearer the front,
a fovea which is as often absent. In very carefully collected speci-
mens the sides of the thorax above have a white efflorescence, and
the body beneath, at sides, seems very densely pubescent, owing to
the efflore.scence between the hairs. This is, however, so easily lost,
one might readily suppose two specimens to be distinct species which
had been unecpially handled in collecting.
The three jnibescent spots on the elytra are, at best, very feeble,
and some care must be used in their observation.
Habits. — Nothing is known to me.

sides regularly arcuate, lateral margin sinuate, hind angles with a fine, short
Carina; disc convex, but irregular, a vague depression in the front and base of
the median line, sometimes a fovea on each side; lateral oblique impressions
distinct, but short; surface vaguely transversely sirigose and punctate; elytra
slightly sinuate behind the humeri, and a little broadened behind the middle
apices subacute and serrulate, disc slightly flattened, the sutural edge elevated
from the middle to the apex ; surface imbricate, more closely at a])ical third and
in the basal foveae, which are modei'ately deep ; body beneath similar in color to
the upper surface, but more shining; prosternal lobe feebly emarginate at mid-
dle, the intercoxal process moderately broad, acute behind the coxae, the pro-
pleurae grauulate-imbricate, sparsely pubescent; metasternum at sides roughly
imbricate. Abdomen finely punctate, very sparsely at middle, more closely at
the sides, the first segment finely strigose, the outer surface including the ver-
tical portion of the segments finely and sparsely pubescent; last ventral segment
very obtuse or truncate ; pygidium coarsely punctate, with a strong carina, w'hich
projects at tip ; claws dissimilar. Length .30 — .32 inch.; 7.5 — 8 mm.
Male. — Front more or less greenish. Prosternuin roughly punc-
tured, more sparsely in front, not pubescent ; first ventral segment
flattened at middle, the second with a smooth but not deep gi-oove
extending two-thirds the length of the segment; anterior tibite feebly
mucronate, middle and posterior tibiie simple ; claws of front tarsi
cleft close to apex, almost bifid, middle or hind claws broadly toothed.
Female. — Front cupreous, and somewhat more convex. Proster-
num but little smoother than the male. Ventral segments simple;
tibise not mucronate; claws broadly toothed on all the feet.
The six specimens before me show no variation. In its general
appearance the species greatly resembles some of the forms of politus.
From the species which seem most closely related to this (anxms
and Blanchardi) the present differs primarily in color, this being
cupreous, they olivaceous. Color characters are, however, not greatly
to be regarded, as great variations do occur. On the male sexual
characters it is better to place more reliance, as these are far more
constant.

male. Thorax one-third wider than long, not narrowed at base, sides regularly
arcuate, margin sinuous, hind angles with a strong arcuate carina in both sexes,
disc convex, with a median shallow depression formed by two fovese, on each
side of middle usually a smaller fovea, lateral depression moderately deep, but
short; surface finely transversely strigose with fine punctures between; scutel-
lum transversely carinate ; elytra slightly sinuate behind the humeri, slightly
broadened behind the middle, apices subacutely rounded, serrulate, disc some-
what flattened with a vague costa, the sutural margin elevated behind the
middle, basal depressions moderately deep; surface rather densely imbricate-
granulate; body beneath more shining than above; prosternal lobe subtruncate,
intercoxal process moderately broad, acute at tip, proplenrse granulate, finely
pubescent; metasternum at sides roughly transversely strigoSe. Abdomen finely
])unctate, s]>arse along the middle, closer along the sides and dense at the side of
the first segment; vertical portions of the segments finely pubescent, apical
segment truncate; pygidium coarsely punctured and with a median carina pro-
jecting strongly at apex ; claws dissimilar on the feet. Length .35 inch. ; 9 mm.
Male. — Prosternum densely punctured between the coxse, more
sparsely in front; surface not pubescent; first and second ventral
segments each with a deep, smooth median groove, that on the second
segment extending nearly to the suture posteriorly ; anterior tibite
very distinctly mucronate, middle less distinctly, posterior tibiie sim-
ple ; claws of middle and anterior tarsi cleft so close to the tip as to
seem bifid, posterior claws broadly toothed at base.
Female. — This sex has not, with certainty, been found among my
specimens. It probably differs from the male in the manner usual
in the group.
In well preserved specimens of this species the underside of the
body is more or less clothed along the side with a whitish efflores-
cence, whereby the pubescence is made more evident, and apparently
more dense.
This species closely resembles pensus and auxins, so that it will be
difficult to separate the females, especially from the latter, but the
ventral characters of the male will enable it to be at once recognized.

segments sparsely ptibescent; pygidium coarsely punctate, the median carina
produced at apex; claws dissimilar on the feet. Length .30 — .45 inch. ; 7.5 —
11.5 mm.
Male. — Front more densely punctured, usually greenish. Proster-
nnni densely punctured between the coxse, more sparsely in front,
not hairy ; fir.st ventral segment vaguely depressed along its middle,
but not smooth, the second with a smooth, deep impression extending
two-thirds to the suture; anterior tibise feebly mucronate, middle
and posterior tibite simple; claws of anterior and middle feet cleft

short, acute tooth.
Female. — Head somewhat' cupreous, less densely punctate. Ven-
tral segments simple; tibiie not mucronate; claws broadly toothed
at basal half. ■
The color of this species is remarkably constant, varying but little
from olivaceous, becoming but slightly green or plumbeous, resem-
bling closely both pensus and Blanchardi, from either of which ref-
erence must be had to the male characters for separation, although
the carina of the hind angles of the thorax is, in both sexes, stronger
and more arcuate than in any species related here. In my cabinet
a male specimen from an unknown locality agrees in all particulars,
except that the hind claws have the same form as on the middle and
front feet, and the angular carina is much less distinct. While it
may represent a different species, it seems preferable to allow it to
pass with mere mention.

metapleuraj and outer side of coxal plates densely punctate and with whitish
pubescence. Abdomen moderately closely punctate, at sides of first ventral

clothed with whitish pubescence, except sometimes on the second segment; py-
gidium coarsely punctate, the median carina prolonged at apex ; claws variable
on the feet. Length .32 — .40 inch.; 8 — 10 mm.
Male. — Front less irregular, the median impression well defined,
but with feeble traces of oblique depressions; anterior and middle
tibite feebly mucronate, posterior tibiae simple ; claws of anterior and
middle tarsi cleft very near the apex, nearly bifid, posterior claws
acutely cleft, but less close to apex ; first ventral segment convex at
middle, the second with a deep, smooth, abruptly formed groove ex-
tending from the finst suture more than half to the second.

defined, the oblique depressions more evident ; tibiae not mucronate ;
claws similar on all the feet, cleft behind the apex, forming an acute
tooth. Ventral segments convex at middle, not grooved.
Variaiiona. — Two well marked varieties may be indicated based
on color, between which there are, however, distinct intermediates.
Var. acutipennis Mann. — Color deep blue, becoming blue-black in
one direction, or slightly olivaceous in the other.
This form is usual in the more southern regions, although my
darkest specimen is from Massachusetts, as well as that intermediate
between the blue form and the next variety.
Var. . — Color olivaceous, the thorax somewhat brassy.
This variety seems confined to the more northern regions of the
country ; in fact, all I have seen are from Massachusetts.
Habits. — j\Ir. Blanchard states that he has taken the acutipennis
form on the foliage of Oak shrubs, the other on foliage of Poplar
si)routs. These observations do not give any positive indication of
the wood into which they bore.

While I have united the two forms with some reluctance I will
admit that I have been unable to find any structural character sepa-

C'oiiosii Lee. — Elongate, somewhat depre.s.sed, slightly concave on the
dorsal line when viewed laterally, color golden-green, moderately shining, sides

antennal fovea, surface very coarsely punctate, occiput slightly strigose. Thorax
one-third wider than long, slightly narrowed at base, sides feebly arcuate, mar-
gin sinuous, hind angles rectangular, with a slight obtuse elevation in the male
and a feeble carina in the female; disc moderately convex, with a broad and
rather deep groove extending from base to apex, sides obliquely depressed, sur-
face punctate and rather coarsely strigose, except on a space each side of median
groove, broadly clothed with yellowish white pubescence at sides: scutellum not
transversely carinate: elytra slightly sinuate behind the humeri, feebly broad-
ened behind the middle, apices obtusely rounded, serrulate, disc comewhat flat-
tened. with a very well defined costa extending from the humeri very nearly to
apex, in latter region slightly sinuous ; surface pubescent, but forming a distinct

densely and finely and with the episterna and outer half of coxal plate pubes-
cent. Abdomen very sparsely punctate at middle, first and second segments with
a densely punctured and pubescent stripe at a distance from the lateral margin,
the next three segments with a pubescent triangular spot at sides, the lateral
marginal line on the first two segments indistinct and sinuous, the vertical por-
tions of the segments densely pubescent; pygidium with a feeble carina, which
does not project ; claws cleft, forming a broad tooth in both sexes. Length .38 —
.44 inch. ; 10- 11 mm.
Sexual characters. — The sexes are differentiated with some difficulty.
I observe that the male has the dorsum less depressed and the carina
of the hind angles merely a feeble elevation.
Very few specimens have been seen, and no variations observed.
This species and cavatus are of an entirely different facies from the
remainder of our species, being of the type more commonly observed
in Mexico. It has been supjiosed to be identical with perkicklns
Gory, an opinion which Crotch thought not well founded.

with a densely pubescent spot at side ; vertical portion of the segments densely
pubescent, except the second ; pygidium coarsely punctate, the carina not pro-
jecting. Length .36 — .,56 inch. ; 9 — 14.5 mm.
Sexual characters. — The males may be known by their smaller size,
more slender form, the abdomen less dilated beyond the sides of the
elytra, the elytral costa better defined, and the tuberosity in the hind
angles of the thorax less so. There are no ventral characters. The
claws are cleft quite near the tip, forming an acute tooth in the front
and middle claws, more broadly toothed on the posterior. The tibite
are not mucronate. The female claws do not differ.
Variations. — When carefully collected specimens are at hand the
elytral vitta extends from the humerus two-thirds to apex, forming
at its end a denser spot, on each side there is a short pubescent vitta
opposite the end of the former and a short distance in the front of
the apex a small pubescent spot. By abrasion the greater ]>art of
the vitta is often lost, and there then remains a basal spot, the denser
end of the vitta and the ante-apical spot.

observed.
Tlie posterior tibite have a form wliich has not been observed in
any other of our species. Near the apex the tibia is rather abruptly
narrowed. The fringe of short bristly hairs which is observed along
the posterior edge of the tibise in all the species in a varying degree
is here present, but ends abruptly at the point at which the tibia is
narrowed.
The facies of this sjiecies is so unlike the style of those of our
fauna, that 1 remained for some time in doubt as to the correctness
of the locality. Recently, however, a specimen has been sent me
from the National Museum removing all doubts.

In the two females before me the underside is purplish black, in-

male, and ])urple in the female.
For this species and one closely allied from Mexico, Mr. Water-
house (Biol. Cent. Am. vol. iii, ])t. 1, p. 50) has suggested the generic
name Eng^jaulus, which he separates from Agrilm by the convex
front, and the mouth consequently more inferior, and the short first
joint of the posterior tarsi. In a study of our species these charac-
ters are shown to have no value, as will be seen by an examination
of the form of the head in the species near which pidchellus is placed
— Walsinghami, obolinus and mntieus. While the first joint of the
hind tarsus is short, it is still equal in length to the next two, so that
when conqiared with these or with the tibia the length is scarcely
less than in very many species before me. From the fact that there
are no valid characters for retaining Engyavlus apart from Agriius
our species is returned to the latter genus.

rowed at apical third, apices rounded, indistinctly serrulate, disc slightly flat-
tened with a vague costa each side, between which and the suture the surface, is
somewhat concave, basal depressions very feeble, surface rather densely granu-
late, more finely in the dorsal groove, surface sparsely clothed with short, fine
pubescence, apparently closer in the groove, giving an appearance of a vitta;
body beneath more brassy than above; prosternal lobe rounded, intercoxal pro-
cess broad, with its apex squarely truncate, i)ropleurfe densely granulate-punctate ;
metasternum at sides closely punctate. Abdomen ratber coarsely and moder-
ately closely punctate, very little more densely at the sides, surface sjjarsely

finely serrulate at the sides near apex; pygidium coarsely punctate, feebly cari-
nate; claws dissimilar in the sexes. Length .24 — .28 inch.; 6 — 7 mm.
Male. — Prosternum densely punctate and with silken hair, which
extends along the middle of the metasternum ; first two ventral seg-
ments slightly flattened, a little more pubescent along the middle ;
claws cleft close to the apex, almost bifid.
Female. — Prosternum less densely jiunctate and less hairv ; ventral
segments convex at middle ; claws cleft at middle, forming an acute
tooth.
No variations have been observed.
The structural characters of this species will enable it to be readily
))laced among those with more or less serrulate last ventral segment,
non-carinate scutellum, elytra! apex nearly without serrulation and
hind angles of thorax but feebly carinate.
Hab. — San Diego, Cal.
.4. polituft Say. — Moderately elongate, slightly depre.ssed on the dorsum,

dle of the thorax, variable in color, serrate from the fourth joint; head slightly
convex, a feeble median depression from the occiput to the middle of the front;
front coarsely granulate, occiput strigo.se. Thorax one-third wader than long,

of the segments sparsely pubescent; last ventral segment finely serrulate at sides
near the apex: pygidium coarsely punctate, feebly carinate along the middle:
claws dissimilar in the sexes. Length .20 — ..34 inch.; 5 — 8.5 mm.
Male. — Front more densely punctured and flatter; prosternuin
densely punctured, hairy ; claws of anterior and middle feet cleft
near the apex, nearly bifld, posterior claws cleft at middle, forming a
broad tooth.
Female. — Front more shining, more convex ; prosternuin less punc-
tate, with short, sparse hair; claws of all the feet cleft at middle,
forming a tooth.
Variations. — In recent specimens the surface is clothed with a very
tine, short pubescence, which gives them a pruinose aspect, the vast
majority of cabinet specimens have no {luhescence.
The differences of color have given rise to several names which do
not seem to he worthy of retention, even as varietal names inasmuch
as the intergrading of color is so gradual as to render it impossible
to separate them.
A. cupreolm Lee. was founded on a uni(|ue of rather larger size
than usual, jeneo-cupreous in color.
.4. poliius Say, is the more common form of cupreous color.
A. pl'iimbeus Vec. founded on specimens of a dull leaden color;
these intergrade with the cupreous and the green forms.
^1. desertiis || Lee. was founded on a single specimen of smaller
size and more brilliant color than the preceding forms. The sculp-
ture is less dense. These may be either bright brassy, blue or green.
Habits. — This species lives on Willows in whatever part of the
country it is found.
Hab. — Canada and the New England States westward to the Pa-
eifle coast, Kansas, Colorado, New Mexico, Arizona, Nevada and
throughout California. In the Atlantic region it extends as far south
as Maryland, but no specimens have been seen from any of the
southern Atlantic or Gulf States nor from the region south of the
Ohio River.
.4. fstllax Say. — Form moderately elongate, dark olivaceous, sometimes
greenish, each elytron with three small pubescent spots. Anteniiie slender and
long, reaching to the hind angles of the thorax, usually greenish, serrate from
the fourth joint; head rather flat, with a feeble median imjiression from occiput
to clypeus, front granulate and alutaceous, occii>ut slightly strigose. Thorax

very little wider than lon.s, arcuate in front, slightly sinuate in front of the
hind angles, which are acutely rectangular and with a sharply defined straight
Carina, margin feehly sinuate; disc convex, with a vague median depression pos-
tei'iorly, lateral ohliqne depressions moderate, surface transversely strigose with
fine, distant imnctnres between ; scuteilum transversely carinate ; elytra slightly
sinuate behind the humeri, feehly dilated behind the middle, ajiices rounded
and serrulate, disc slightly flattened with a very vague costa, basal depression
feeble, surface imbricate, on each elytron three round pubescent spots, basal,
ante-median and one-third from apex; body beneath more hi'assy tlian above;

and alutaceous, at sides somewhat strigose. vertical portion of the segments
sparsely pubescent; jiygidium coarsely punctate, carinate at middle anteriorly;
claws dissimilar. Length .16 — .24 inch.; 4 — 6 mm.
Male. — Head Hatter, more oitaque and more granulate, usually
green ; prosternum densely punctate and with rather long pubes-
cence ; metasternum Hat, densely punctured ; first two ventral seg-
ments longitudinally impressed at middle, their entire length, sparsely
pubescent ; claws of anterior tarsi cleft very near the apex, nearly
bifid, middle and posterior claws cleft at middle, forming a broad

convex ; prosternum sparsely punctate, not hairy ; metasternum
slightly convex, simply {)unctate ; first two ventral segments convex
at middle ; claws cleft at middle, forming a broad tooth ; tibife not
mucronate.
Variations. — Slight variations in color will be seen as usual in the
dark species. The median impression of the thorax may consist of
an anterior fovea or a feebly impressed median line.
When the pubescent spots are removed by abrasion, this species,
especially the smaller specimens, greatly resembles egenus, and great
care must be used in separating them, but the serration of the an-
tennae is quite different in the two species.
Of its habits I know nothing.
Hab. — Canada southward to Louisiana and Texas, westward to
Nebraska.
A. obsoletOgiittRtiiS Gory. — Form slender, elongate, color brassy black

portion of segments not conspicuously pubescent; pygidium coarsely punctate,
carinate at middle; claws cleft near the middle, forming a broad tooth. Length
.'24 — .32 inch. ; 6—8 mm.
Male. — Front usually green, more densely punctate; prosternuin

second ventrals rather roughly granulate at middle.
Female. — Front less closely punctate, ajneous or cupreous; jtro-
sternum more shining, not hairy; tibim not mucronate; ventral
segments simply punctate.
Variations. — No variation of moment has been observed. Badly
preserved s|)ecimens are often without spots, but the elongate narrow
form of the insect will make it easily known.’
This species is especially notable in the long slender legs. The
hind tarsi are especially elongate, being longer than the tibia, the
first joint longer than half the tibia.
Habits. — Found on the foliage of Oak shrubs.
Hah. — Massachusetts westward to Illinois, south to N. Carolina.
A. scitiiliiM u. sp. — Form oi fallax ; head aud thorax brassy, elytra dark
olivaceous, with pubescent spots as in ohsoleto-gnttatus. Antennae slender, reach-
ing the hind angles of the thorax, serrate from the fourth joint, more or less
teneous; head viewed from above slightly convex, front with a broad, but shal-
low depression i)unctate aud obliquely strigose, occiput longitudinally strigose,

tured with a pubescent spot in the basal depression, a larger spot behind this not
reaching the middle, exterior to the end of which is a very small spot, one-third
from apex a small I'ound spot; body beneath more shining than above; proster-
nal lobe rather broadly and deeply emarginate, intercoxal process broad, parallel
and with rounded apex, propleurse finelj’ punctate and strigose, sparsely pubes-
cent; metasternum at sides densely punctate and with the outer half of coxal

first two segments midway between the middle and side and on the third seg-
ment at the side, vertical portion of segments sparsely pubescent; pygidium
coarsely punctate, indistinctly carinate ; claws broadly toothed at middle. Length
.18— .20 inch. ; 4.5 — 5.5 mm.
Male. — Prosternuin densely jumctate, finely pubescent, the pubes-
cence extending on the front of the inetasternuin ; first ventral seg-
ment slightly flattened at middle, not pubescent ; anterior and middle
tihiie distinctly mucronate.
Female. — Unknown.
This species is not especially conspicuous among those with ornate
elytra. With the form of fallax or egenus, the markings, when per-
fect, resemble those of obsoleto-guttatiis, and from any of them the
structural characters either of the antennae, legs or prosternum will
.separate.
Hab. — The few specimens examined were collected by Belfrage in
Texas, probably at Waco.
.4. oruatiilii»$ n. sp. — Form of egemis, but a little stouter, piceous, elytra
somewhat shining, ornamented with pubescent spaces, thorax opaque. Antenna*
attaining the middle of the thorax, piceous, serrate from the fourth joint; head
convex, with a very feeble impression of the occiput, front convex, indistinctly
punctate, smoother at middle. Thorax a little wider than long, sides regularly
arcuate, margin absolutely straight, not deflexed in front, hind angles rectan-
gular^ without trace of carina, disc convex without depressions, merely slightly
concave along the side, surface punctate, obliquely strigose at middle, longitudi-
nally at the sides; scutellum transversely carinate ; elytra sinuate behind the
humeri, broadened behind the middle, apices rather obliquely rounded without
serrulation, disc depressed at middle, a very vague costa each side, basal depres-

bending obliquely outward and backward, apical third entirely pubescent, the
anterior edge oblique on each side; body beneath with distinct aeneous lustre;
prosternal lobe broadly and deeply emarginate, intercoxal process slightly broad-
ened behind the coxae and obtuse at apex, propleurae feebly punctate; metaster-

Sexual characters. — The only points noticed in the nninerons speci-
mens examined are found in the more opafpieand sctmewliat nigulo.se
prosternum of the male, while it is sjiarsely punctate and smoother
in the female.
No variations have been olxserved, the markings .seeming very
constant. In some specimens there will be observed a golden hue
about the margins of the pubescent spaces.
Hab. — Southwestern Texas, no precise locality known.
\, n. sp. — Form oblong, subcylindrical, cupreo-ffineous, moder-
ately shining, elytra with faint siibsutural pubescent vitta. Antennte piceous,
faintly bronzed, attaining the middle of the thora.x. serrate from the fourth
joint; head convex, with a faint median impression from the occijiut to the cly-
peus, coarsely not closely i)unctate. Thorax nearly square, sides feebly arcuate,
margin .straight, deflexed in front, hind angles rectangular, without trace of
Carina, di.sc convex, without depressions either at middle or sides, not concave
along the margin, surface ]mnctate along the middle, vaguely strigose at the
sides ; scutellum indistinctly carinate ; elytra slightly sinuate behind the humeri
and dilated behind the middle, ai>ices rounded, finely serrulate, disc convex, the
basal depressions feeble, surface rather coarsely and roughly imbricate with a
sparsely pubescent subsutural vitta extending from the base iiearly to the apex ;
body beneath seneous; prosternum acutely but not deeply emarginate at mid<lle,
not wide between the coxa, tip not acute, propleurre |)unctate, sparsely pubes-
cent; metasternum at sides transversely strigose, somewhat reticulate in cei tain
lights. Abdomen sparsely punctate, with distant striga* at the sides of the first
two segments, suhreticulate in appearance, the posterior edge of the second, and
to a less degree the third segment, prolonged at middle in a short laminate pro-
ce,ss, which occupies one-third the width of the segment; claws toothed near the
base. Length .13 inch.; 3.5 mm.
Unfortunately, tlie two specinieu.s before me of tins species present
no special characters of a sexual nature. The prosteruum is some-
what rugose and slightly pubescent, and the first ventral roughened
at middle of base, and from these feeble characters they are assumed
to be males.
The most curious character observed is in the v'^entral segments,
and seems unique in the genus. The posterior edge of the second
ventral segment is free and slightly prolonged in an arcuate manner
over the next .segment. The same in a less degree is observed on the
third segment. This may prove to be a male peculiarity.
The sculpture of the disc of thorax viewed in certain lights seems
reticulate, as in some Anthaxia, and the elytral sculpture very
coarse for so small a species.

seneons, serrate from the fifth joint; head slightly convex, a feeble median im-
pression from the occiput to the clypens. the latter broad at base, surface rather
coarsely punctate and obliquely strigose. Thorax a little wider than long, sides
regularly arcuate, slightly sinuate near the hind angles, which are rectangular
and without trace of a carina, lateral margin sinuous, disc convex, without trace
of median sulcus, lateral oblique impression feeble, surface rather closely punc-
tate with feeble obliijue strigse, sides pubescent, more broadly behind ; scutellum
transversely carinate; elytra very slightly sinuate at middle and slightly broad-
ened. apices rounded, serrulate, disc, convex, basal depression feeble, surface
rather coarsely imbricate and with a vitta of whitish pubescence from the base
to the apex close to the suture; body beneath cupreo-teneous ; prosternal lobe
truncate, with a feeble emargination at middle, the inten'.oxal proc^ess narrowed
from base to apex, the tip obtuse, propleurje punctate, with scale-like white hairs
and effloresence ; metasternum at sides irnbricately sculptured and with the
ejiisternum and outer half of coxSl plate clothed with white inibescence. Ab-
domen moderately closely imbricate, more roughly at the sides of the first two
segments, clothed along the sides with whitish pubescence, vertical portion of
first segment with white pubescence; pygidium coarsely punctate, feebly cari-
nate; claws broadly toothed at middle. Length .25 inch. ; 6.5 mm.
Male. — Prostenium coarsely punctured, s[)arsely pubescent ; first
two ventral segments roughly sculptured at middle; anterior tibia
distinctly, middle tibia feebly mucronate, the posterior simple.
Female. — Prosternum less closely punctate, scarcely hairy ; first
two veutral segments simply punctate ; tibite all simple.
Variaiiom. — The three specimens before me seem to have been
collected with care and have a rather dense efflorescence between the
hairs, so that they seem very conspicuous. It is |)robable that speci-
mens collected in alcohol or wet in any way, lose the efflorescence,
and the pubescent spots will appear le.ss distinct. There is no varia-
tion in the specimens examined.

first two segments strigose and somewhat reticulate, the vertical portion of first
segment pubescent ; pygidium indistinctly punctate, carinate along the median
line ; claws broadly toothed. Length .24 inch. ; 6 mm.
The male differs from the female in having the prosterniim slightly
more densely punctate and the first two ventral segments more ru-
go.se at middle. Five specimens have been examined, four of which
are in the National Museum.
This species is not conspicuously marked, but among those in which
the antenntc are serrate from the fifth joint it may be known by the
very convex thorax, with feeble median depression, the absence of
angular carina and the feeble j)ube.scent spots of the elytra.

occiput to the clypeus, surface relatively coarsely strigose. Thorax wider than
long, sides regularly arcuate, margin sinuate, hind angles rectangular, without
trace of carina, disc convex, with a rather broad but not deep median depression
extending from base to apex, lateral depression well marked, extending toward
the base, surface transversely strigose at middle, obliquely at sides, punctate near
the margin; scutellum transversely carinate; elytra slightly sinuate behind the
humeri, dilated somewhat behind the middle, apices rounded, serrulate, disc
slightly flattened with a vague costa, sutural margin elevated, except at basal

find any well marked secondary sexual characters. One specimen,
seemingly a male, has the prosternum somewhat more opaque and a
little more pubescent.
Varmtiom. — The usual variations dependent on abrasion must be
expected here as elsewhere. While the vast majority of specimens
have the antennce serrate beginning with the fifth joint, one in my
cabinet begins at the fourth, that is, the fourth joint more nearly
resembles the fifth than the third. Such cases as this must be classed
as abnormalities, and are very confusing to a systematist, or to one
attempting to determine sjiecific names with but little material.
Hab. — Canada to North Carolina, westward to Illinois. It is not
recorded from the New England States, but probably occurs there.
A. piitilliiM Say. — Form nearly of subcinctus ; dark olivaceous bronze, mod-
erately shining. Antennae scarcely attaining the middle of the thorax, piceous,
serrate from the fifth joint; head convex, with a feeble occipital impression,
front s])arsely indistinctly punctate, slightly alntaceous. Thorax one-third wider
than long, sides regularly arcuate, margin sinuous, hind angles rectangular
without trace of carina; disc convex, with a feeble linear median impression,
lateral depressions deep along the side, surface transversely strigose, but more
evidently punctate near the apex; scutellum transversely carinate ; elytra ex-
tremely little sinuate at middle, apices rounded, serrulate ; disc slightly depressed
at middle, a feeble basal fovea, on each side a suhcostiform elevation, between
which and the suture on each side the elytra are vaguely channeled, surface
imbricate, hut not closely; body beneath usually darker, hut more shining than
above; prosterual lobe subtruncate, sometimes feebly emarginate, intercoxal
process relatively broad, obtuse at apex ; propleurae comparatively smooth ;
metasternum at sides rather finely punctate and substrigose. Abdomen sparsely
punctate over the entire surface and faintly alntaceous ; pygidium very indis-
tinctly punctate, not at all carinate; claws broadly toothed at middle. Length
.12 inch. ; 3 mm.
Male. — Front greenish, more opaque and more closely sculptuTed.
Prosternum more closely punctate along the middle and slightly pu-
bescent. Abdomen simple, not roughened at base.
Female. — Front aeneous, more shining and more sparsely punctate.
Prostern u in not pubescent.
Variations. — The color is very constant. The discal cosUr of the
elytra vary considerably in their distinctness, and are sometimes
nearly absent. In the outline of the upper surface, when viewed
laterally, some are nearly straight, others quite arched.
This species is the smallest found in the Atlantic region proper,
and is remarkable in having the lower angle of the eve acute.

Variations. — None have been observed in the many specimens
seen .
This species, like ventralis of the preceding series, resembles
Taphroceras a.griloides, and in the present rather more so than in that
from the fact that there is here no pubescent elytral vitta.
When the thorax is viewed fi'om above and from behind, the
scul|)ture has a reticulate appearance, but when seen from in front
is very obliquely and not closely strigo.se.

'File three specimens of tliis species examined were all females, .so
that I am unable to state the sexual differences. They show no
variation.
This species resembles Lecontel (subfasciatus) so closely, that I
found it mixed with that s[)ecies in my own and another cabinet.
The form of the prosternal lobe will, however, separate them at once.
Suiierficially, the sculpture of the middle of the thorax will distin-
guish them. In this species there is a straight depression, Avhile in
Lecontel there are two depressions, anterior and posterior united by
a narrower depressed space.
Hab. — Texas, no special region known.
A. paliliaeolliN n. sp. — Moderately elongate, piceoiis, with bronzed surface
lustre, moderately shining, each elytron with three pube.scent spots as in fallax.

from the fifth joint; head convex, with a slight occipital impression, front rather
coarsely punctate, occiput strigose. Thorax wider than long, sides feebly arcuate,
sinuate in front of the hind angles, which are rectangular and i-ather feebly
carinate, margin straight, scarcely deflexed in front; disc convex, without me-
dian imiiression, lateral depressions feeble, surface very obliquely strigose, but
not closely; scutellum transversely carinate; elytra feebly sinuate at sides,
slightly broader behind the middle then obliquely narrowed to apex, a])ices ob-
liquely rounded, serrulate ; disc slightly depressed, basal fovea* feeble, on each
side three pubescent spots, as in fallax; body beneath as abf>ve : prosternal lobe
obtusely rounded, iutercoxal ju-ocess relatively broad, truncate at tip, propleurse
punctate; metasternum at sides roughly punctate and substrigose. Abdomen
spar.sely punctate, strigose at sides of first two segments, vertical portion of first
segment densely pubescent with white; pygidium spar.sely punctate, feebly
carinate; claw's broadly toothed. Length .12 — .18 inch.; 3 — 4.5 mm.
Male. — Head very densely punctate, cupreous. Prosternum
sparsely pubescent; first two ventral segments impressed at middle,
more deejily on the first.
Female. — Front less punctate, teneous. Prosternum scarcely pu-
bescent ; ventral segments simple.
The numerous specimens examined are constant in appearance,
varying only in size.
There are but few species so obliquely strigose ou the thorax as
this one, the strigosity beginning at the middle and running diago-
nally forward, Tho.se so sculptured are I'eadily known by their
structural characters.
Hab. — Western Texas and southern Arizona (Morrison).

pubescence. Antennae short, scarcely reaching the middle of the thorax, piceous,
strongly serrate from the fifth joint; head feel)ly convex, a vague median im-
pression more evident in the female, surface rather roughly punctate-strigose.
Thorax as long as wide (male), or a little wider than long (female), sides nearly
straight 'J, , or slightly arcuate 9, hind angles rectangular, with a fine straight
Carina, more evident in the J, margin sinuous; disc regularly convex, without
median or lateral depressions, surface rather coarsely transversely strigose, with
a pubescent space at sides, broadest behind, enclosing the carina; scutellum
transversely carinate ; elytra scarcely sinuate behind the humeri, apices rounded,
more acute and more distinctly serrulate in % ; disc with a very vague costa,
between which and the suture, in a slight channel, is the pubescent vitta; sur-
face moderately closely imbricate; body beneath geueous, with fine short pubes-
cence; prosternal lobe obtusely rounded, the iutercoxal process rather broad,
truncate at tip, propleurse punctate and pubescent; metasternum at sides closely
punctate and somewhat strigose. Abdomen moderately closely finely punctate,
denser at sides of first segment; pygidium sparsely punctate, not carinate ; claws
dissimilar in the sexes. Length .22 — .24 inch. ; 5.5 — 6 mm.
Male. — Front flatter, tlie median imprecision feeble. Thorax as
long as wide, tlie sides nearly straight. Prosternuin roughly punc-
tate, sparsely pubescent. Abdomen simple, the first segment rather
rough at middle ; claws on all the feet cleft very near the apex,
almost bifid ; tibite simple.
Female. — Head more convex, the median impression deeper. Tho-
rax a little wider than long, the sides moderately arcuate. Proster-
num less rugose, scarcely pubescent. Abdomen le.ss rugose ; claws
broadly toothed.
Variation. — In this species, as in others already noted, there is be-
tween the pubescence a whitish efflorescence, which makes the pu-
bescence seem denser and whiter, but when this is removed by acci-
dental moistening the reverse is produced.
This species resembles jacobinm, of the preceding series, in form
and color, but differs in the form of the antennm and the presence
of the pubescent vitta. It resembles still mure blandus but that
has no trace, whatever, of carina in the hind angles, and the proster-
nal lobe is more distinctly emarginate.
Hab. — Arizona, probably near Tucson.
A. iiii|>exii!it u. sp. — Subcylindrical, slightly flattened above, dull cupreo-
seneous, each elytron with three indistinct pubescent spots. Antennae not reach-
ing the middle of the thorax, piceous, with slight aeneous lustre, serrate from
the fifth joint; head broadly, but feebly coucave, with a median impressed line,
surface closely punctate-strigose. Thorax scarcely wider than long, the sides
very feebly arcuate, slightly sinuate near the hind angles, which are rectangular
and distinctly carinate, margin sinuous; disc convex, with a median depression
variable in distinctness, and when well marked with an impressed line at bottom

toward the sides : scuteliiim transversely carinate ; elytra feebly sinuate behind
the humeri, the apices rounded, serrulate; disc slightly flattened, but not snlcate,
basal depressions feeble, surface closely granulate-imbricate, somewhat strigose
at sides in front, each elytron with three faint pubescent spots, one at base, one
in front of middle, the posterior one-third from apex; body beneath more shin-
ing than above ; prosternal lobe obtusely rounded, iiitercoxal process rather wide,
parallel, trinicate at apex, propleurie closely strigose punctate; metasternum at
sides coarsely transversely strigose. Abdomen moderately closely punctate,
more or less strigose over the whole surface, but more coarsely at the sides of the
first two segments; jiygidium indistinctly punctate, feebly carinate; claws
broadly toothed. Length .27 — .29 inch. ; 7 — 7.5 mm.
Male. — Front more closely punctate, but rather less concave.
'riiora.N with a feebler median impression without impressed line.
Prosternum densely punctured, sparsely pubescent, the pubescence
extending on the metasternum, which is flattened and closely punc-
tate ; first two ventral segments vaguely sulcate their entire length
and pubescent in the depression ; tibiie simple.
Female. — Head less closely punctate, the concavity a little more
jironounced ; median depression of thorax well marked with a fine
impressed line at bottom. Prosternum less densely punctate, scarcely
pubescent. Metasternum slightly convex ; ventral segments not
impressed.
Variations. — In the two specimens before me the variations have
been alluded to, and seem to be sexual.
'fhe pubescent spots of the elytra are not distinct in either speci-
men, except at base of elytra, but are very plainly indicated by the
denser and finer punctuation. Closely resembles Jinridanus, but in
the latter the ])ygidium is not carinate, and there is scarcely a trace
of median impression of the thorax.
Hub. — Arkansas and Nebraska.

pressed above, bright cupreo-ieneous, each elytron with three pubescent spots.

head slightly concave with a fine median impressed line, surface closely punctate-
strigose. Thorax one-fourth wdder than long, slightly narrowed at base, sides
feebly arcuate, slightly sinuate near the posterior angles, which are rectangular,
and with an obtuse, straight carina, margin sinuous; disc convex, a flattening
or slight depression in front of the .scutellum, lateral oblique impressions well
marked, surface transversely punctate-strigose, but not roughly ; scutellum trans-

arranged in the usual manner; body beneath more sliining than above; proster-
nal lobe truncate and vaguely einarginate, intercoxal process rather broad, trun-
cate at apex, propleurse coarsely punctate, sparsely pubescent; metasternum at
sides rather roughly strigose and punctate. Abdomen moderately closely punc-
tate, strigose at sides of first two segments; pygidium sparsely punctate, with a
smooth median line; claws cleft, forming a broad tooth. Length .28 inch. ; 7 mm.
Male. — Prosternum densely punctured, pubescent; first two ven-
tral segments very feebly impressed along the middle, scarcely pu-
bescent ; tibite not mucronate.
Female. — Prosternum less roughly punctate, not pubescent ; ven-
tral segments not impressed.
The two specimens before me do not vary. The types are before
me and show that while the species is fairly, but too briefly described
by Crotch, its position in his analytical table is erroneous. He men-
tions pubescent patches at the sides of the last three ventral segments,
but this is merely the result of a slightly denser punctuation.
Hah. — Northern Florida, probably near Jacksonville.
A. addeiidiis Crotch. — Moderately robust, dull cupreo-aeneous, subopaque,
elytra with three pubescent spots on each side, sometimes absent or very faint.

very little wider than long, slightly narrowed posteriorly, sides feebly arcuate,
slightly sinuate in front of hind angles, which are rectangular and with a
straight, well defined carina; disc convex, with at most a feeble median impres-
sion, which may he entirely absent, lateral oblique impression moderate, surface
closely transversely strigose; scutellum transversely carinate; elytra feebly
sinuate at sides and but little broadened, apices rounded, feebly serrulate ; disc
slightly flattened, a vague channel each side of suture, basal fovese feeble, surface
moderately closely, but not roughly imbricate, the pubescent spots, when present,
as in fall ax ; body beneath more shining than above; prosternal lobe obtusely
rounded, with a vague sinuatiou at middle, intercoxal process parallel, squarely
truncate at apex, propleurfe shining, indistinctly reticulate; metasternum at
sides roughly punctate-strigose and with the episternum and outer side of coxal
plate pubescent. Abdomen sparsely punctate, strigose at sides of first two seg-
ments, the vertical portion of first two segments densely pubescent ; pygidium
sparsely punctate, not carinate; claws broadly toothed. Length .1,5 — .24 inch.;
4 — 6 mm.
Male. — F rout with simply the longitudinal depression. Prosternum
densely punctured and hairy. Metasternum flat, as densely punc-
tured as the prosternum ; first two ventral segments feebly impressed
along the median line.

Yarlatiom. — Two forms may l)e separated in this species, those
witli tlie i)ubescent spots well marked and those without them. The
former variety shows some pubescence at the sides of the thorax and
at the sides of the last three ventral segments. Those without spots
show in nearly all the specimens the spaces with denser fine punc-
tuation, but even this may be absent. In the typical specimens, as
Crotch states, there is a tendency to form a basal and subapical spots.
Between the specimens with no spots and the others I have every
necessary link in my cabinet.
The median thoracic imjn'ession is, at best, faint, but in some speci-
mens entirely wanting, in others represented by a slight antescutellar
depression.
Hah. — d'exas (Belfrage), Arizona.
.4, laciistris Lee. — Moderately elongate, nearly parallel, slightly depressed
above, color variable, dark bronze, green or bine. Antennfe piceous. not reaching
the middle of the thorax, serrate from the fifth joint: head convex, a feeble
median furrow from the occiput to the middle of the front, surface roughly
puuctate-strigose. Thorax scarcely wider than long, the sides feebly arcuate,
slightly sinuate near the hind angles, these rectangular with a short fine carina,
margin straight, deflexed in front only; disc convex, sometimes with a vague
median impression, the lateral depressions absent, surface transversely and
rather closely strigose, with fine punctures; scutellum variable, either carinate
or not; elytra feebly sinuate at sides and but little dilated behind the middle,
apices rounded, serrulate; disc slightly flattened, basal fovea feeble, surface
closely and rather roughly imbricate; body beneath more or less blue; proster-
nal lobe broadly rounded, intercoxal process rather broad, truncate at apex, pro-
pleurse strigo.se and punctate, sparsely pube.scent ; metasternum at sides trans-
versely strigose, not roughly nor closely. Abdomen transversely strigose, not
roughly nor closely; pygidium sparsely punctate, not carinate; claws broadly
toothed. Length .16 — .30 inch.; 4— 7.5 mm.
Male. — Front scmiewhat more opaque. Prosternum densely punc-
tured and hairy. Metasternum concave ami hairy; first two ventral
segments rather deejtly impressed their whole length, the impression
hairy; tibite simple.
Female. — Prosternum coarsely sculptured, transversely strigose,
but not hairy. Metasternum slightly convex, transversely roughly
strigose, not hairy ; ventral segments not imjiressed.
Vaviatmu. — The color varieties have already been recorded. The
blue forms are, however, very rare. The scutellum may be trans-
versely carinate or not, sometimes the carina is interi-upted in the
middle. Fully developed specimens usually have the carina very
distinct; in the small and feeble forms it is wanting. The same is
true of the feeble median depression of the thorax.
NORTH AMKKICAN COLEOPTERA.
331
This species was originally named from some small and feeble forms
from the North, which, at first sight, are very unlike the larger forms
from the Texan region. It is also evident that LeConte had speci-
mens of another species along with his types as tlie so-called male is
really that of defedus. At present the specimen is not found with
tlie types, having |)robably been removed either by himself or Crotch.
The larger Texan forms were described l)y LeConte as cuneus from
a single specimen in Ulke’s cabinet. From not finding a type in the
LeConte cabinet. Crotch subsequently named the specimens in my
cabinet pubiventris.
Hah. — Illinois, Lake Superior region; Lapointe, Missouri; Texas,

.4. egeims Gory.— Moderately elongate, olive bronze, sometimes slightly
greenish. Antennie rather slender, reaching the middle of the thorax, joints
longer than wide, the third obviously shorter than the fourth, piceous. slightly
bronzed, serrate from the fifth Joint: front Hat. a very feeble median impression,
densely punctate, occiput strigose. Thora.x wider than long, sides not strongly
arcuate, hind angles rectangular, with a well defined, slightly oblique carina,
margin nearly straight, deHexed in front; disc convex, without median depres-
sion, lateral oblique depressions well marked, surface transversely strigose with
fine punctures between; scutellum transversely carinate ; elytra feebly sinuate
at sides, slightly broader behind the middle, apices rounded, serrulate, basal
fovefe moderate, disc slightly depressed, surface imbricate; body beneath rather
more shining than above; prosternal lobe truncate, more or less emarginate, the
intercoxal process narrowed at apex, propleur® sparsely punctate; metasternum
at sides asperately punctate. Abdomen very sparsely punctate ; pygidium sparsely
punctate, not carinate ; claws broadly toothed. Length .14 — .20 inch. ; 3.5 — 5 mm.
Male. — Front more densely punctate, more opaque, bluish green.
Prosternum densely punctured, hairy, the hair extending somewhat
on the metasternum ; first two ventral segments flat or feebly ini-
pressed at middle, slightly pubescent.
Female. — Front slightly more convex, the punctures coarser and
less clo.se, more shining, teneous. Prosternum not hairy ; ventral
segments not impressed.
Farndm/i,s.— Notwithstanding the wide area over which this spe-
cies is distributed, there seems to be no variation, except slightly
in color and size. Some of the narrower forms with a slight greenish
color resemble offo.sqt.s considerably, but the structure of both antenuDe
and claws will separate them. On the other hand, some of the forms
oi fallax deprived of pubescence are apt to be mixed with the present
species, and are not easy to separate without great care, but the form
of the antenme and the flat base of clypeus in the present sj)ecies
will render them separable.

The numerous specimens examined show no variation, except a
little in size in specimens from the most remote localities.
The species resembles egenus somewhat, but is more robust, has
shorter antenme and an entire prosternal lobe. Specimens of lacus-
tris have been seen which somewhat resemble this one, but the male
characters will then readily separate them.

.4. piisilliis Say. — Form of aclimiuutive rujicollis ; head and thorax usually
seueous or cupreous, elytra purple-hlack (but variable), moderately shining. Au-
teunse reaching the middle of the thorax, piceous, serrate from the fifth joint,
serrate joints wider than long; head convex, a feeble median impression from
the occiput to the base of the clypeus, surface moderately closely coarsely punc-
tate. Thorax wider than long, slightly narrowed at base, sides arcuate in front,
slightly sinuate near the hind angles, which are rectangular and distinctly cari-
nate. margin nearly straight, deflexed in front, disc convex, a broad transverse

the thorax is more convex in the anterior half, lateral oblique depression mod-
erately deep, surface moderately coarsely transversely strigose, with coarse punc-
tures in the grooves; scutellum carinate or not; elytra sinuate at the sides,
distinctly dilated behind the middle, apices rounded, serrulate ; disc flattened,
usually a vague costa on each side, a feeble concavity each side of the suture,

Variations. — The general aspect of this species is that of a diminu-
tive rujicollis with the thorax less conspicuously cupreous. The tho-
rax is often brassy with purplish spaces at the sides. Sometimes the
elytra are seneous. These last forms resemble jjutillus, but these
have no carina in the hind angles of the thorax, and the disc has a
distinct median impression.

GEO. H. HORN, M. D.
This species was placed by LeConte in the group with the incurved
tootli of the claws, but the claws and an ten life are both different from
that series.
The name parvus has been suggested for this species by Saunders
in “ Catalogus Bnprestidarum,” but there seems to be no valid reason
for the the change. It is certainly ])ermissible to use jnisUhis and
putillus in the same genus.

On a collection of Hyinenoptera made in Jamaica
during April, 1891.
BY WILLIAM J. FOX.
The collection on which this article is based was made in Jamaica,
during April of the present year, by myself and Mr. Charles W.
Johnson, of the Wagner Free Institute of Science, Philadelphia.
About seventy species are giyen herein, which will be increased to
nearly one hundred when the Formicidie and a number of species
of Andrenidie have been classified.

PAPER II*
BY C. H. TYLER TOWNSEND.
The study of the Tachinidse has progressed considerably of late
in the line of descriptive work. Up to within a few years a large
number of forms, necessitating the foundation of new genera, had
remained unnoticed. iNIr. van der Wulp has given us descriptions
of a considerable number of these, which, however, are mainly con-
fined to Old Mexico. Messrs. Brauer and von Bergenstamm have
erected a great number of genera from all parts of the w’orld, some
of which can be em})loyed ; but many are unfortunately either based
on invalid characters, or insufficiently de.scribed and without figures
to enable their recognition. A few other authors have contributed
isolated descriptions of genera in this grou]). Notwithstanding these
recent additions I believe it necessary at this time to erect a number
of new genera for the reception of forms herein described, which
cannot be reconciled with any of the published descrii»tions or figures
of previous genera.
The present jiaper is the result of a study of a considerable col-
lection of material, all from within the limits of the United States ;
and will, the writer hopes, contribute toward a more accurate know-
ledge of our many species among these useful parasitic Hies.
SIPHOPLAGIAf 11. gen.

in the 9 ( ? abdomen narrower in S ). Eyes bare ; front wide,
prominent ; frontal liristles strong, descending but little below the
base of antennae ; a strong pair at each vertical angle directed back-

retracted, oral margin prominent, facial ridges bare ; vibrissse decus-
sate, inserted near the oral margin ; cheeks broad, one-half the
liight of eyes in 9 ( ? narrower in S ), bare, with a fringe of bris-
tles on the lower and front border, extending but slightly above the
vibrissie. Anteniue little more than two-thirds the length of the
face ; first joint short, second somewhat elongate, third almost twice
the length of the second, not widened, rounded at the end ; arista

reaching to base of third abdominal segment ; still a third shorter
lateral pair. Abdomen ( 9 ) long oval in outline, flattened, vaulted,
first segment abbreviated ; macrochsetse of abdomen all marginal
on segments one to four. Legs moderately long. Wings with a
small costal spine ; apical cell ending on the front border of the wing
very much before the apex, narrowly open or almost closed in the
margin ; hind cross-vein very oblique, arising ojiposite or a little
behind the small cross-vein, approximating the bend of the fourth
longitudinal ; apical cross-vein also oblique, both nearly parallel with
the hind border of wing; fourth vein with a very long stump at its
angle; third vein spined on the proximal two-thirds of its extent.
Type, S', anomala n. sp.
This genus diflers from Plagia, as above stated, by the structure
of the proboscis, and the absence of rows of bristles on the sides of
the face ; also by the macrochsetie being only marginal. It agrees
with it in all other essential characteristics.

and cheeks silvery-white polliuose; front fully one-half the width of head,
shaded with cinereous; frontal vitta brownish, anteriorly about one-third the
width of the front, widening behind where it sj)lits on each side of the ocellar
area; four pairs of ocellar bristles, a rather weak pair at the vertex directed
outward and backward, but inclined forward at the point, a weaker pair Just in
front of these directed forward and a little outward, a strong pair farther in
front directed widely outward and but very slightly forward, and a weak pair
iniinediately outside the last directed outward and more forward, weak bristly

proach V. (1. Wulp’s Flagia incognita, but it has a long stump at the
bend of the fourth vein, and the abdomen is nearly uniform cinereous
pollinose instead of hlack with gray front borders to tlie segments.

Genus Tachinodes Br. and Bgst., Zweifl. kais. Mus. W. iv, 133.
This genus, so far as I can ascertain from comparison, of the descrip-
tions, is the same as N^einochoeta v. d. Wulp. Mr. van der Wulp’s
genus has priority, as it was described in 1888 (Biol. C.-A. Di})t. ii,
38). The above authors give no figure of their genus Tachinodes,
which was erected for Tachina hystrix Fab. from Brazil.

moderately narrow, grayish hyaline, .slightly pale tawny at base, with small costal
spine, third vein wdth a few spines at base; apical cell nearly closed in the mar-

bend; hind cross-vein nearly straight, oblique, nearer to bend of fouiTh vein;
tegulse nearly white, margins slightly yellowish; halteres fuscous, yellowish at
base. Length 6 mm. ; of wing 4.5 mm.
Described from one specimen received from Mr. Chas. Robertson,
Carlinville, 111. This is a good, typical Taehina in the sense of
Schiner; the only difference being in the nearly closed aj)ical cell.
Doubtless, further specimens will show the apical cell to be normally
more open.
Taehina aletise Riley, Can. Ent. xi, 162.
As the eyes are described “ thinly pubescent,” this is not a Trichina.
Besides, the third antennal joint is said to be “three or four times
the length of the second,” while in Taehina it is at most twice the
length of the elongate second. The description is insufficient to
indicate the genus. The surmise would be that the sjiecies belongs
in Exorista.

about the same width. Length 51 — mm. ; of wing 4 — 4S mm.
Described from one % and three 9 specimens received from Mr.
Cliarles Robertson, Carlinville, 111. Differs from Schiner’s description
of }facronychia as follows : Tbe sides of face are narrow and bare ; the
front is rather narrow, and of equal width in both sexes ; the arista
is seen to be distinctly 3-jointed under a high-power lens. It belongs
to Pachyophthahmis Br. and Bgst. as separated by them from Mucro-
nyc.hia; and on account of still other differences beside those men-
tioned above may perhaps better be located in the new genus. It
has the front narrower than in Miltogramma.
(lavicoriiis n. sp. % . — Black, cinereous and reddish.
Eyes light brown, bare, facets larger in front; front a little over one-fourth width
of head, rather prominent before, brassy or slightly golden, with some short,
weak hairs outside the frontal bristles; face much wider than front; frontal
vitta brownish, very narrow before, widening toward ocelli, where it divides into
a prong on each side; face and cheeks silvery-white, facial dei)ressiou occupying
one-half the width of face, sides of face, therefore, moderately wide, bare; frontal
bri.stles de.scending only to base of antennae ; a pair of posteriorly directed bris-

ward); the usual two pairs of ocellar bristles, front pair directed strongly for-
ward and somewhat outward, the shorter hind pair directed a little outward ;
cheeks wide, invaded under the eyes by the occijiital area, otherwise bare, with
bristles on lower and forward borders; vibrissfe decussate, inserted well above
the oral margin at a coirstriction of the facial ridges, which are bristly fora short
distance above them; face hardly straight, a little oblique, epistoma hardly
promineut ; antenme a little more than one-half length of face, flavous, first joint
extremely short; second of moderate length, well clothed with short, black bris-
tles, and with a long straight bristle on front border; third joint about twice
the length of second, not widened, light flavous; arista black or dark brown,
bare save for a microscopic pubescence, thickened about half its length, distinctly
8-jointed, the second joint a little elongate; proboscis black, about as long as
bight of head, not thick, labella considerably developed ; palpi flavous, rather
loTig, slender, thickened at tip, with several fine, black bristles on under surface;

with appressed black bristles; first segment hardly shortened, blackish, reddish
below and on the side.s, sometimes above on the hind margin except in middle;

dian black vitta very narrow in front and much widened behind ; third segment
reddish in front, silvery, broadly blackish behind, the posterior widened portion
of the median vitta more distinctly shining black ; anal segment broadly silvery
in front, the median posterior portion blackish ; the silvery pollen of the segments
has much of a golden tinge in some lights, especially on the anal segment; venter
mostly orange, blackish at anus ; first and second segments without macrochsetie ;
third .segment with about eight rather weak, marginal macrochffitje, the outer
ones only a little stouter than the bristles of tbe abdomen; anal segment with

lected near Carlinville, 111., which I am confident are S and 9 t)f
the same sjiecies, although both of them have the facets of the eye

enlarged in front, and the one with the short claws seems to have the
front slightly narrower. The claws of the other are very elongate.
1 have a very much smaller S received from Mr. Robertson with
the above, which is only 4.5 mm. long. It has the claws and pul-
villi elongated and very closely resembles the larger S , which is
6.5 mm long. I hesitate to describe it from one specimen, as it seems
to differ only in its very much smaller size and darker abdomen.
The abdomen is but slightly reddish on sides of second segment, rest
blackish, silvery pollinose. The arista, however, is not so distinctly
jointed. It differs from the following two species in its brassy or
golden front, and long flavous third antennal joint. In case it is
recognized from this description and found to be distinct, it may be
called M. simills.
The only differences between the above described Miltogrammas
and Schiller’s generic description are that the arista is quite distinctly
3-jointed, and the third antennal joint is about twice the length of
the second.
,^Iiltoj;raiiima argentif roiis a. sp. 'J, . — Differs from M. flavicornis a,s
follows: Smaller, without red ou abdomen. Front silvery, iucludiug vitta, sides
darker iu some lights; only three orbital bristles; frontal bristles not so nu-
merous or closely set, rather sparse; anteunse entirely dull blackish, except
apical rim of second joint, which is light yellowish, third joint scarcely longer
than the second ; arista black, thickened only at base, bulbous, indistinctly
jointed; sides of face finely hairy ; facial depression narrow, scarcely any bris-
tles on facial ridges above the vibrissse ; palpi blackish or dark brown ; apical
scutellar pair of macrochsetse sometimes not, but usually decussate. Abdomen
blackish or dark brown, light cinereous pollinose, no distinct median vitta ; first
segment with a weak lateral macrochgeta on the margin ; second with a lateral
marginal one and a median marginal pair; third segment with eight marginal,
and anal segment with six marginal, as in the above species. Claws and pulvilli
elongate. Tr«(f/s smaller ; halteres flavous. Length 4 — 5.5 mm.; of wing 3.5 —
4.5 mm.
Described from four % specimens received from Mr. Charles
Robertson, Carlinville, 111. One of these specimens is much larger
(5.5 mm.) than the three others (4-4.5 mm.), and also differs in hav-
ing a median macrochteta (its mate probably lost) on margin of first
abdominal segment. The sides of the face are only very slightly hairy.
It does not otherwise differ appreciably.
Mlltogramma trilineata v. d. Wulp, Biol. C.-A. Dipt, ii, 89. One
specimen from S. Illinois (Robertson) I believe should be referred
to this species. It much resembles, but is larger than M. argentifrom
Towns.

Described from one specimen received from Mr. Chas. Robertson,
Carlinville, 111. This species I have located temporarily in Masicera,
although it does not (piite agree with the characters of that genus.
The ajiical cell is opened only a little before the wing’s tip, and the
form is rather narrower than is usual in Masicera. It apparently
approaches Telothyria v. d. Wulp, but differs from it by the promi-
nent front, receding face and distinctly 2-jointed arista. Additional
specimens will be needed to decide its location.

This genus can hardly be confused with Fhorocera, to which it
bears some resemblance. The facial ridges are bare, but the frontal
bristles descend in a row just outside the facial ridges, and near
enough to cause reasonable doubt as to whether they should be con-
sidered cdiate. Besides this distinction, the ej es aie bare, and the
apical cell is closed.

Described from two specimens ; a % from Prof. J. M. Aldrich,
Brookings, South Dakota, and a 9 from Prof O. Lugger, Minn. (?)
have })referred to locate this species in the genus Apliria, although
in some features it closely approaches OUvierla, but differs from it
also in others very essentially. The jiroboscis is long, but bardly
bristle-like and not horizontally protruded. It is straight and per-
pendicularly extended, of about the same size and length as in
Ocyptera, but, unlike that genus, possesses well-formed palpi. The
eyes are extremely thinly pubescent and the apical cell closed in the
margin, both of which characters lead to Aphria in Schiner’s table,
but are denied it in his generic characterization. From Olivi.eria it
differs in the receding (not almost perpendicular) face, in the longer
and more slender proboscis, and in the absence of discal macrochpetic
on the abdominal segments.

as this species, ditfers as follows:
Head fully as wide as thorax; front nearly one-third width of head, sides
golden pollinose; frontal bristles normal, extending back nearly to vertex, the
two posterior ones on each side (not counting vertical bristles) directed back-
ward ; the pair of bristles at each vertical angle much longer ; two orbital bris-
tles; antenna; a little longer, third joint larger, crooked, bowed outward ; palj)!
more yellowish. Thorax not widened. Abdomen narrower, only a little broader
than thorax, with no red on sides, the anal segment nearly all deep fulvous;
first segment without macrochsetse, second with a median marginal pair in addi-
tion to the lateral marginal one on each side; third segment with ten marginal
macrochtetfe, anal segment not so bristly. Claws and pulvilli but little elongate.
Wings not so pointed toward tip ; third vein spined at base. Length 8 mm. ; of
wing 6.5 mm.

This is not the genns Madpoda Br. and v. Bgst., but connects that
genus with Exorista. It belongs in the vicinity of E. tricolor v. d.
Wulp from iNIexico.
Exorista Jiaviccmda Riley. This species shonld he known as Eron-
tina Jiavicauda Riley. Two specimens from ]\Ir. Charles Robertson,
collected in South Illinois, agree well tvith the descri[)tion and tignre,
and belong to the genus Frontina.

less faint rufous tinge on the sides of the second abdominal segment.

De.scribed from one specimen received from Mr. Chas. Robertson,
Carlinville, 111. This species may be looked upon as connecting the
two genera, Frontina and Acroglossa. It has the arista nearly as in
Acroglossa, sometimes subgen icnlate, while it pos.sesses the proboscis
of Frontina. In general appearance it greatly resembles Acroglosm
hesperidarvm. The whole fourth abdominal segment, however, is
reddish or orange. It further differs from ^4. hesperidarum as fol-
lows: the cheeks do not have bristles, but they are clothed with fine
bristly hairs. The sides of face are golden, and the first abdominal
segment bears a median j)air of macrochaetie on its hind margin, as
well as the second segment, though they are weaker. This specimen,
a % (?), also has the third antennal joint scarcely three times the
length of the second.
Kiplioiia u. sp. 9- — Deep golden, cinereous. Eyes dark

This genus seems to a])proach Eggeriu somewhat. It did'ers very
markedly, however. The arista is clothed with very short pubes-
cence; the sides of the face are not broad ; the facial ridges are hare,
while the frontal bristles extend down in a row almost to the vi-
hi’issie ; the front is not prominent, and the face is not so receding as
in Eggeria ; the eyes are only thinly and short hairy, chiefly on their
lower portions; the antenme are shorter than the fiice, the palpi are
filiform, and the abdomen is sub-conical.

Carlinville, 111. This species, from the elongate legs, lias quite a
Dexiid asjiect, but is evidently projierly placed in the Tacbinidat,
for the reason that the frontal bristles descend nearly to the vibrissie,
and the arista is only short pubescent.

This genus is near Beskia, but the proboscis is curved backward
at tip, instead of forward, and the third joint of antennae is not
widened and truncate at apex.

This new genus and species is described from California, and was
Itred from adults of Diabrotica soror. It is described as having five
abdominal segments, wdiich would properly exclude it from the Tach-
inidte sens, str., and it would fall in the Phaniidte by its other char-
acters. The first or basal segment is, however, as long as the second,
and the so-called fifth segment is probably not a segment properly
speaking, but merely the more or less concealed caudal joint or hy-
poiyygium to be found in many Tachinidte s. sti‘. In the OcyjJeridm
and Phaniidm, as \vell as in the Phasiidte, the first segment is much
shorter than the second, and it is at the ba.'ie of the abdomen that
the additional segment must be looked for.

Belongs in the Phytoinaj, perhaps in the neighborhood of Myo-
thyria v. d. Wulp. Tlie arista, however, is distinctly 3-jointed, while
the peculiar proboscis will at once distinguish it from other genera.

the head very slightly wider. Eyes bare ; front and face rather wide,
from one-third to three-fifths the width of the head ; distance between
the eyes at vertex and cheeks the same. Sides of face bare, very
narrow below, gradually widening to base of antennae ; cheeks bare,
rather narrow, with some bristles on the lower and forward margin ;
the nearly decussate vibrissae inserted on the oral margin. Frontal
bristles descending but little below the base of antennae, about to
base of third joint; a pair of unequal length at each vertical angle,
the shorter outer one directed outward, the other directed backward ;
next two frontal bristles on each^side directed backward, remainder
directed inward ; two orbital bristles on each side directed forward.
Face receding, epistoma somewhat prominent ; facial ridges bare.

elongate. Proboscis quite widely extended, about three times as
long as hight of head, bristle-like, once geniculate, the distal portion
sometimes very strongly curved or bowed, usually considerably
bowed, but sometimes almost straight, labella somewhat developed ;
j)ali)i filiform, hardly thickened toward tip. An apical and lateral
pair of scutellar macrochsetje, the former longer, not decussate, and
reaching a little more than the base of second abdominal segment.
Abdomen elongate oval, sometimes shorter oval, first segment not
abbreviated ; macrbchsetae all marginal on segments two to four.
Legs moderately long, tarsi rather elongate and delicate. Wings
broad, longer than the abdomen, with costal spine, third vein spined
only at base; apical cell ending very slightly before the tip of the
wing, much narrowed on its distal portion, usually clo.sed in the
border, but often very narrowly open ; posterior cross-vein sinuate,

This genus is readily distinguislied from Siphona, to which it bears
a slight resemblance, by the ))roboscis not being twice geniculate,
and the arista with the second joint not elongate. It is apparently
very near Spiroglosm Dol. of the East Indies.

longer black bristles directed backward ; a median posteriorly divergent pair of
grayish brown vittae becoming obsolete near transverse suture; humeri and
pleurte silvery; two bristles below humeri directed outward, forward and up-
ward ; a vertical row of bristles directed posteriorly in front of base of wings,
three bristles on next sclerite below, front pair directed outward and forward,
and the hind one outward, backward and upward. Abdomen above very light

some shorter ones below ; fourth segment with six macrochteta; ; venter cou-
colorous, anus dark. very light yellowish, finely black hairy; coxae with
black bristles on forward surface directed posteriorly; femora with some weak
black bristles, the longest being on underside of hind pair; tibiae with some
shorter bristles, tarsi thickly covered with very short black hairs; claws and
pulvilli a little elongate, about half as long as last tarsal joint. Wings grayish
hyaline, wing veins light tawny; tegulae whitish, shining, margin narrowly
opaque, white ; halteres white. Length 4 — 5.5 mm. ; of wing 3.5 to nearly 5 mm.
Described from thirty-three specimens taken on windows of Agri-
cultural College building, June ‘29th to July 8th, Las Cruces, N.
Mex. Some specimens differ in the frontal vitta being of equal
width, wider than base of antennte in front, occupying throughout
one-half or more of the frontal width. The probo.scis is often not
so much bowed, sometimes nearly straight. The tar.si of some are
shorter, particularly the distal joints, the claws and pulvilli being
apparently a little less elongate. Yet these differences by no means
constantly acconi[)any each other ; I am, therefore, uncertain of the

sexes. The smallest individuals have the front and face only one-
third the width of the head, and, were it not for their short claws
and pulvilli, I should consider them to be the males. I believe,
however, that the males are the larger ones with longer claws, wider
front, and more strongly bowed proboscis.

Described from one specimen from Mr. Charles Robertson. Car-
linville, Jll. This species bears a considerable resemblance to a
Hyalomyia, in the form of the head, antennae, rather weak frontal
bristles, eyes, front, ])roboscis, palpi, abdomen, elongate tarsal claws
and i)ulvilli, and even in the curved fourth vein. It is to be easily
distinguished, however, by the rather weak but distinct macrocbaette
of the abdomen; only four abdominal segments; the fourth vein
not describing a perfect curve as in Hyalomyia, but somewhat an-
gular ; and the large tegulae.

segments rather narrowly silvery white ]iollinose, the whole covered with short,
appressed black bristles; first and second segments with only a median pair of
macrochaetse ; third and fourth segments each with eight erect macrochaetae, and
some shorter macrochaeta-like bristles on the concolorous venter. Legs black,
black hairy, silvery and bristly except tarsi and front tibiae; claws and pulvilii
not elongate. Wings obscure grayish hyaline, costal border and borders of veins
fuscous; tegulae pure white, halteres fuscous or brownish. Length 7.5 — 8.5 mm. ;

Described from two specimens taken July 20th. Las Caaices, X.
Mex. This is a beautiful and striking species. Although the frontal
bristles do not descend on the face and the arista is short feathered,
this species seems to claim close I’elationship with Atrophopoda. The
front claws and pulvilii in both are minute, and the general facies is
strikingly the same. It is possible that a greater amount of mate-
rial in this sub-group may demonstrate the affinities of one or both
genera with the Dexiidse.
Genus Arthrochceta Br. and Bgst., Zweifl. kais. Mus. W. iv, 134.
This genus is not sufficiently characterized to stand. It is prefixed
to a species called by the authors A. demoticoides, from Columbia,
the short specific characterization of which at the end of the woi’k
throws no light on the matter.
Note on the Dexiid genus Uromijia Rob.-Desv. — The writer has
published a note on this genus (Proc. Ent. Soc. Washington, ii, 100)
calling attention to the fact that the name was first employed by
Robinean-Desvoidy, and afterwards applied by IMeigen, or a name
so nearly like it as to be misleading and confusing, to a Phaniid. In
order to avoid confusion in the use of the word, I ])ropose for Meigen’s
genus the name Neouromyia.
Note on the Dexiid genus Tropidoniyia Br. and Bgst. — Brauer
and V. Bergenstamm (Zweifl. kais. INIus. W. iv, 119, 1889), have
erected a genus which they called Trop>idomyia, for a Dexiid from
Syria. The name is preoccupied; Dr. Williston applied it to a
South American Conopid, which he described in “Can. Ent.,” Jan-
uary, 1888. Brauer’s genus must, therefore, be given another name,
and I propose that of Neotropidomyia.
