Form cylindrical, rather massive ; head rather large, inferior ; e3'es
round, prominent ; clypeus truncate, labrum transverse ciliate in
front ; mandibles stout, pyramidal, acute at tip ; maxillae ciliate at
tip, the palpi moderate in length, slightly ciliate, the last joint elon-
gate-oval ; nientum transverse, emarginate (ligula and palpi absent
in my specimens) ; antenniie inserted between the eye and base of
mandibles, ten-jointed, first joint as long as the next four, second
as wide as long, joints three to seven broader than long, obconical,
slightly flattened, last three joints forming a loose club which is as
long as joints two to seven together and more than twice as wide,
the joints of the club wider than long ; thorax very convex, oboval,
broader than long with asperities antero-laterally ; scutellum oval at
tip ; elytra not flattened, the extreme tip sinuately truncate ; pro-
sternum very short in front of the coxoe, these ovate, contiguous, the
cavities confluent and very narrowly enclosed behind ; middle coxae
moderately separated, the mesosternum oblique ; metasternum mod-
erately long, the episterna wide, parallel, the posterior coxpe very
narrowly separated ; abdomen with five equal segments ; legs mod-
erate, the tibiae dilated and strongly dentate externally ; tarsi rather
slender, nearly as long as the tibite, the first joint short, second as
long as the fifth, second and third short and equal, last joint with a
rather long onychium, the claws strong and arcuate ; body winged.

The characters given above indicate a genus closely related to
Bostrychus aud Amphicerus, and like the latter without frontal mar-
gin, but with a slight projection over the base of the antennae. The
head is not so completely inferior as in those genera nor are the fii-st
two joints of the antennae as short in comparison with the next five.
The most striking difference, however, is in the structure of the tibiae
with the outer edge strongly dentate.

The first fragments of this genus received by me consisted of a
hind body and a head without mouth parts, excepting the mandibles.
Supposing the head (which I now know to be larval) to belong to
the fragments of body, the genus has been characterized in verbal
remarks made before the Academy of Natural Sciences as eyeless,
and therefore the largest blind Coleopter known. The discovery of
additional material enables me now to correct an error which has
unfortunately appenred in print.

I>. Wriglltii n. sp. — Black, shining, beneath brown sparsely pubescent ;
head broader behind the eyes, finely punctate, a vague median frontal impres-
sion ; thorax oboval broader than long, nearly as wide as the elytra, very convex,
densely granulate in front and posteriorly, roughly asperate at the sides ante-
riorly ; elytra parallel, declivous posteriorly, the apices sinuately truncate, the
sutural angle acute, the disc vaguely bicostate, the costse terminating in tuber-
culiform elevations ( 9 ) or with the inner costa prolonged in a spine ( % ',, the
surface above with shallow cribrate punctures, the sides smoother and with two
indistinct costse beneath the humeral umbone ; legs moderate, femora sparsely
punctate ; body beneath rather finely punctate, the abdomen more densely and
with pale brownish pubescence. Length 1.50 - 1.86 inch ; 38-47 mm.

The measurements are taken from the apex of the elytra to the
anterior margin of the thorax ; the smaller specimens are females.
A size is thus indicated exceeding any Bostrichide known.

For the fragments in my possession I am indebted to the untiring-
exertions of Mr. W. G. Wright, of San Bernardino, Cal, a zealous
Botanist, for whom neither the privations incident to an exploration
of the Mojave Desert nor the jealous watchfulness of the Lidians,
seemed to have had any terrors.

Mojave Desert, California.

As the habits of this insect and its larva are now being investigated
by Mr. Wright, I refrain from mentioning any matters of this char-
acter, as comparatively little is known except its food plant. It is to
be expected that in the near future we will have fiill details from him.
Should it prove to infest but the one plant it is likely to be at all
times rai-e, and i)ossibly to disappear.

NORTH AMERICAN COLEOPTERA.

Description of Larva.

Form robust, convex, the ventral surface flat, gradually narrower from the
prothoracic to the last segment, the last four segments recurved, their ventral
surface in contact with that of the pi-eceding segments ; color whitish, con-
sistence soft.

Segments twelve ; three thoracic, nine abdominal.

Prothorax large, massive, somewhat narrowed in front, flat above, yellowish
white, a dorsal and two lateral fuscous spaces, the latter including an elevated
serrate line ; spiracle large, fusiform in outline.

Meso- and Metathoracic segments consisting of a dorsal and infero-lateral
piece, the latter as seen from the side larger ; these segments without spiracles.

Abdominal segments. The first two consist of two dorsal pieces, the division
indicated by a fold merely, the spiracles in these segments smaller than the pro-
thoracic and situated in a rhomboidal depression between the dorsal and infero-
lateral plates ; segments three to eight gradually less distinctly divided on the
dorsal portion, the spiracles in each gradually smaller and situated at the lower
end of the dorsal division. Last segment obtusely ovate, scarcely plicate dor-
sally and without spiracle, the anal opening ventral and longitudinal.

Spiracles. Of these there are nine on each side, all functional ; the first is
situated at the side of the prothoracic segment, tlie others in the first eight
ventral segments ; they gradually decrease in size from the first to the last.

Legs on the three thoracic segments nearly equal, with four articulations, the
femoral piece longer, the tibia terminated by a small cleft claw, the under por-
tion of which is short ; surface of legs rather hairy.

Head very deeply inserted in the prothorax ; the exjiosed portion dark chiti-
nous, the internal ovate flattened on the under side, the anterior margin of head
forming a thickened projection, the clypeus hemi-hexagoual with a chitinous
border.

Labrum transverse, ciliate, the anterior margin arcuate.

Mandibles stout, pjTamidal, the apices chisel shaped, transversely wrinkled
above ; behind the base of the mandibles an oval tubercle of the side of the head.

Maxilla with a large, irregularly quadrangular, basal piece, surmounted by
an oval lobe, the inner edge of which is truncate, the surface densely ciliate ;
the palpi 3- jointed, the first largest, obovate, second narrower and shoi"ter, the
third slender, subuliform.

Mentum trapezoidal, the sides arcuate, apex truncate, face obliquely impressed
each side ; the subnientum broader, of the same general form ; jjalpi similar to
the maxillary, but nuich swollen, the ligula concealed by them, semi-circular,
the palpi and ligula rather densely pilose.

Antenna small, situated near the base of the mandibles above the oval tu-
bercle, 3-jointed, the first joint short, cylindrical, second narrower and longer,
the third small, slender and bisetose at tip.

This larva reproduces the form and nearly all the details of Apate

capucina as published by Ferris (Ann. Fr. 1850, pi. xvi, 1). The

antennte are there described as 4-jointed, but the conical basal piece

as described seems rather to be the protuberant conneetmg membrane.

4 GEO. H. HORN, M. D.

The other parts figured by Perris are rather diagrams than real ilkis-
trations. The accompanying figures will give a fair idea of the imago
and the larva, obviating the necessity for a very detailed description.

The head of the larva is remarkable in its size and the perfection
of the mouth ^^arts. It is entirely without trace of visual organs,
although it is probable that the post-mandibular tubercle becomes
the eye in the imago.

It is probable that the larva figured on the accompanying plate is
fully grown. Two specimens were kindly sent me by Mr. W. G.
Wright, one of which will be placed in the Museum of Comparative
Zoology at Cambridge, for the use of those who have occasion to
studv the instructive series of larvae there acccumulated.

NORTH AMERICAN COLEOPTERA.

A monograplt of the species of the snb-faniilies EUCIVE-

MIN^, CEROPHYTIX.E and PEROTHOPIN^

inhabiting the ITnited f§ttates.

BY GEORGE H. HORN, M. D.

After the grand monograph of the Eucnemides completed by de
Bonvouloir, in 1875, the present essay seems almost unnecessary, but
to the vast majority of our students the book is inaccessible.

As might have been expected a small number of our species re-
mained unknown to de Bonvouloir, which are in their correct places
in the following pages, and in addition four have been described
since, while ten new ones, besides, have been collected.

Regarding the status of the species treated there has been some
difference of opinion. In the early days of the science the Eucne-
mides were considered Elateridae and a number described as Elater,
later in the posthumous work of Latreille we find them recognized
as a tribe of Elateridae. In a synopsis of the Eucnemides (Proc.
Acad. 1852, p. 45) Dr. LeConte uses the following words : " Although
many entomologists consider that the small group of Coleopterous
insects herein treated constitute a peculiar family I am under the
necessity, after very careful examination, of viewing them as a mere
section of the extensive natural family of Elateridae, and no more
entitled to a distinct place in the series than any other group of
genera in that family." The same ideas were repeated the next year
in his " Revision of the Elateridae" (Trans. Am. Philos. Soc. x).

It Avas not until 1857 that Lacordaire recognized the Eucnemidae
and Elateridae as families of equivalent standing with the Buprestidae.
This view was finally adopted liy Dr. LeConte in the first edition of
the " Classification," and de Bonvouloir follows in accord excluding,
however, Perothops from the Eucnemidae as a troublesome element
without definitely assigning it a place.

Realizing these difficulties it was suggested by me (Trans. Am.
Ent. Soc. vii, 1879, p. xxi) that Cerophytum and Perothops should
be isolated, and that the term Elateridae should be so extended as to
embrace the aberrant forms, those to be considered sub-families. The
relations of these various series to each other are fully explained in
the " Classification" of the Coleoptera of N. A. edit. 2, and need not
here be dwelt upon.

6 GEO. H. HORN, M. D.

The present essav purposes to deal with the three sub-families
named, the Cebrionin^e having been already treated, and the Elater-
in^ is of sufficient magnitude to require its being dealt with in a
fragmentary manner, as has been begun in the last few years.

EUCNEMINJE.

Head convex, mouth inferior, labrum absent, or very slightly visible ; clypeus
more or less inflexed, narrowed at its base by the insertion of the antennie ; pro-
thorax movalile, but less so than in the Elaterinje ; prosternum without lobe in
front ; hind coxal plates laminate.

The Eucneminae may be divided into two tribes in the following
manner :

Anteunte moderately distant ; last joint of maxillary palpi acute ; jirostenial
sutures and side margin parallel Melasini.

Antennse approximate ; last joint of maxillary palpi dilated ; prosternal su-
tures and margin convergent Eucneiniiii.

Tribe Melasini.

In this tribe the head is rather broad and less deeply inserted, so
that the eyes are free and the mouth not apj^lied against the pros-
ternum.

Two genera are known.

Tibia' broad, compressed Mela!«is.

Tibia? slender Tliarops.

MELA!§»IS Oliv.

Form elongate, subcylindrical ; antennte not passing the middle of the thorax,
distinctly pectinate % or feebly so 9 ! head rather large, moderately convex ;
clypeus feel)ly narrowed at base, apex emarginate at middle and sinuate each
side ; prothorax wider than long, anterior angles obtuse, the posterior acute and
slightly prominent ; lateral margin entire, but not prominent ; prosternal sutures
distant and parallel, the lateral marginal lines also nearly parallel with them ;
no antennal grooves on the. under side of the thorax ; metasternal episterna
covered in front by the elytra, visible posteriorly, epimera concealed ; hind coxal
plates very broad internally, narrow externally ; last ventral segment tubularly
prolonged, with an ante-apical elevation, segments one to four slightly elevated
at the middle of the posterior margin ; legs rather short, the femora stout, the
tibiae flat and rather broad, terminated by a single spur ; tarsi robust, rapidly
attenuating, the first joint as long as the next three, all joints simple, claws
simple.

Melasis and Tharops are considered by Bonvouloir to form a group
apart from the other Eucnemides characterized by the parallel pros-

NORTH AMERICAN COLEOPTERA. 7

temal sutures and the lateral margin of the thorax. In all the
specimens of Melasis which I have examined I can find but one
tibial spur, a character which seems to have escaped mention.
Two species are known to me from our fauna.

Third joint of antenupe % nearly twice as wide as long, the fourth nearly
three times; color piceous, or nearly black pectiiiicoriiis.

Third joint of antennse % distinctly longer than wide, the fourth very little
wider than long; elytra and antenna? rufo-ferruginous rufipeiiiii!!).

As males only of the latter sj)ecies are known to me I am unable
to give characters separating the females.

m. pectinicoriiis Mels. — Form elongate, subcylindrical, piceous or black,
opaque, sparsely clothed with extremely short grayish pubescence ; antennse
barely attaining the middle of the thorax, brown or ferruginous, the first joint
piceous, joints four to ten strongly % , or feebly pectinate 9 ; eyes small, round,
feebly convex ; head coarsely, closely and roughly punctured, a slight impres-
sion of the vertex, more distinct in the male ; prothorax broader than long,
slightly narrowed posteriorly, the sides straight at middle, broadly % or feebly
9 arcuate at the front angle, rather deeply sinuate in front of the hind angles,
which are acute and divergent % , or scarcely perceptibly sinuate, the angles not
divergent 9 > disc convex, a distinct median impressed line deeper in the % , the
surface coarsely punctured, with elevated granules ; elytra slightly narrowing
posteriorly, their apices acute, surface with rather deep punctured striae, the
interv'als slightly convex, densely granulate and rugose ; body beneath densely
punctate ; legs piceous, tibiae and tarsi paler. Length .24 - .32 inch ; 6 - 8 mm.

In the female the thorax is much more deeply emarginate in front
and the head relatively smaller, the surfiice less rugose and the granu-
lations of the thorax more distant.

Occurs from Pennsylvania to Texas, but very rare. For an op-
portunity of examining the female I am indebted to Mr. H. Ulke.

M. rufipennis n. sp. — Form elongate, subcylindrical, slightly narrowed
behind, piceous, subopaque ; pubescence fulvous, scarcely visible, elytra and
antennae rufo-ferruginous ; antenna?, attaining the middle of the thorax, the
third joint nearly twice as long as the visible (in front) jiortion of the second,
joint four triangular, broader than long, five to ten gradually more prolonged
anteriorly, but less so than in pectinlcornis : eyes small, round, feebly convex ;
head densely and rather coarsely punctate, not rough ; clypeus slightly concave,
front sometimes with a slight transverse carina ; thorax a little wider than long,
slightly narrower behind, sides straight, slightly arcuate at the apical angles and
with a feeble sinuation in front of the hind angles, which are acute and slightly
divei-gent ; disc moderately convex, densely punctured and roughly granulate,
with a narrow median smooth line very distinctly impressed posteriorly ; elytra
gradually narrowed posteriorly, the apices acute, disc deeply striate with coarse
punctures, the intervals convex, densely punctured, but more shining than
above ; legs piceous, tibiae and tarsi brown. Length .36 - .42 inch ; 9 - 19.5 mm.

8 OEO. H. HORN, M. D.

This species is evidently closely allied to rnfipalpis Chev. from
Mexico. The color is different, but this may be an accident, although
I have seen three specimens from different localities taken in different
years, all alike. In one specimen before me the transverse carina of
the front is slightly distinct, in the other absent. The striae of the
elytra are coarsely punctured.

Occurs in Nevada and Washington Territory.

THAROPS Cast.

Form slender, subcylindrical, more or less narrowed posteriorly ; antennae
sligMly passing the hind angles of the thorax, flabellate from the fourth joint
% ; head moderately convex ; eyes round, entire ; clypeus slightly narrower at
base, apex bisinuate ; prothorax a little longer than wide, lateral margin entire ;
scutellum oval, truncate at tip ; elytra striate, not entirely covering the abdo-
men ; prosternal sutures straight, very nearly parallel with the lateral margin,
the ijropleura; not excavate for the antennse ; metasternal episterna very narrow
in front, broader posteriorly, the epimera visible ; posterior coxje gradually
wider internally, the posterior margin internally, truncate ; legs moderate, tibise
slender, tarsi filiform, the first joint as long as the next four, the fourth small
and simple ; claws simple.

This genus forms with Melasis a small group differing from the
other members of the Eucneminfe in having the prosternal sutures
and lateral margin of the thoraxi parallel, the two genera differing
at first sight in the form of the tibiae.

Two species are known in our fauna.

Elytra with inconspicuous pubescence rufleornis.

Elytra with dense silken pubescence forming a distinct design iiubila.

T. ruficornis Say. — Form subcylindrical, slightly narrower posteriorly,
piceous black, elytra variable in color, usually with an elongate, triangular, su-
tural. yellowish "space, surface very inconspicuously pubescent ; antennse not-
passing the hind angles of the thorax, rufo-ferruginous ; head coarsely and
densely punctured, front above the clypeus slightly depressed % ; clypeus nar-
rowed at base, not wider than the distance to the eyes ; thorax longer than wide,
sides nearly parallel, slightly arcuate near the front angles, hind angles short,
not carinate ; disc moderately convex, median line ususally impressed, surface
coarsely, moderately densely punctured ; elytra striate, intervals slightly con-
vex, moderately densely, roughly punctured ; prothorax beneath rather coarsely,
but not densely punctured ; metasternum more densely ; abdomen more finely
and densely punctured, last ventral segment acute at tip ; legs rufo-ferruginous.
Length .14 - .32 inch ; .3..5 - 8 mm.

Male. — Antennse rufo-ferruginous, first joint rather robust, second small,
partly concealed, third as long as the three following joints, joints four to ten
short, each, however, gradually longer and narrower, furnished with a branch
as long as the entire antennae, eleventh as long as the branch of the tenth, but
stouter ; the middle of the posterior margins of the third and fourth ventral
segments slightly elevated in a mucro.

NORTH AMERICAN COLEOPTERA. 9

Female. — Antennae rufo-ferruginous, the basal joint sometimes darker; first
joint stout, second small, partly concealed, third as long as the next two, fourth
triangular, longer than the fifth, joints five to ten triangular, a little wider than
the fourth, subequal in length, but gradually wider, eleventh oval, nearly as
long as the next two ; last ventral segment acute at tip, penultimate segment
elevated at middle of posterior margin in a distinct mucro.

The males are usually smaller and more slender than the females,
and have often a slight transverse impression of the middle of the
thorax.

The median line of the thorax is a very variable character, often
the line is rather deeply impressed posteriorly and ends abruptly, it
may also continue slightly to the apical margin or be entirely vv^anting.

The elytra are variable in coloration. I have a specimen entirely
piceous, another with a small spot at base on each side of the scutel-
lum, from this the yellow space becomes gradually longer and may
reach nearly to the apex.

The male does not seem to have been known to Bonvouloir, and
very few of the other sex. I am entirely unable to separate two
species in the large material I have examined. The males are much
less frequent than the females.

Occurs from Canada and New Hampshire to Missouri and Vir-
ginia.

T. nnbila. Bonv. — Form elongate cylindrical, scarcely narrower behind,
entirely black, moderately densely clothed with sericeous fine pubescence form-
ing a distinct design ; antennse (rufo-testaceous?) wanting; head rugosely punc-
tured ; thorax as long as wide, sides straight posteriorly, slightly arcuate in
front, disc convex a distinct depression of the median line posteriorly, very
densely and finely punctate, surface in front marked with two rings of cinereous
pubescence ; elytra striate, strife finely punctured, the intervals finely granulate
toward the base, and slightly rugose posteriorly ; covered with dense ashy-gray
pubescence, forming a transverse band at middle, which is narrower at the su-
ture, oblique each side in front, the apical fourth also densely pubescent with a
small portion of the apex uncovered ; under side of body entirely black, inner
side of the posterior coxae and legs ferruginous. Length .20 inch ; 5 mm.

This species I have never seen. It is known to me by the descrip-
tion and figure given by Bonvouloir and a drawing made by Major
LeConte from the same specimen.

The only specimen known was collected more than fifty years ago
by Major LeConte in Northern Georgia and sent to Count Dejean.

Tribe Eucnemini.
The head is not very broad, the mouth resting against the anterior
margin of the prosternum, the eyes at least in contact with the thorax
often partly concealed.

TRANS. AMER. ENT. SOC. (2) JANUARY, 1886.

10 GEO. H. HORN, M. D.

Tlie different genera present so many modifications of structure,
while preserving the same general type, that it is unnecessary here
to deal more fully with them as they more properly belong to the
generic descriptions.

This tribe is the equivalent of the Eucnemitea propres as defined by
de Bonvouloir, and contains eighty-seven genera, twenty of which
are represented in our fauna. Having less material to deal with
than he, I have been enabled to modify the table of genera in such
a way as to use characters more readily seen and to avoid exceptional
cases. For the latter i-eason I have been compelled to avoid the use
of the coxal plates near the beginning of the table, inasmuch as two
species of Microrhagus have parallel coxal plates and might be sup-
posed to belong to Hylochares.

The characters used in the following table seem not to require
special explanation, in case of doubt reference should be made to the
genera themselves.

Thorax with anteuual grooves usually sharply limited, close to the lateral

margin 2.

Thorax without marginal antennul grooves 8.

2. — Tarsi with joints 2-4 lobed beneath Deiidrocliaris.

Tarsi with the fourth joint, at most, slightly lobed 3.

3. — Pi-osternal sutures arcuate ^itetlioii.

Prosternal sutures straight 4.

4. — Antennal groove continuing directly from the thorax to the head 5.

Antennal groove more or less interrupted or narrowed by the eyes 7.

5. — Metasternum with a fine groove, limited by finely elevated lines, pro-
longed backward from the outer side of the middle coxae ; propleural

triangle small Eiieiieiiiis.

Metasternum without groove 6.

6. — Antennal groove of thorax wide, at least equal to half the propleural

triaiagle, usually wider behind Deltoiuotopu^^.

Antennal groove narrow, not more than a fourth as wide as the propleu-
ral triangle, not wider behind Droin»M>lii!$.

7. — Antennge slender, fourth joint of tarsi excavate-emarginate and slightly

lobed beneath Fornax.

Antennse short, clavate, fourth joint of tarsi simple ....Pliaoii<»('ei*u»<«.

8. — Lateral margin of thorax formed by two finely elevated lines, the one

starting from the anterior margin and prolonged backward, the other

from the hind angles becoming inferior ; antennal grooves juxta-su-

tural 9.

Lateral margin of thorax single, sometimes nearly entirely obliterated;
under side of prothorax without antennal grooves, at most a faint lon-
gitudinal depression in the triangle 10.

9. — Juxta-sutural groove very short, merely slightly indicated in front.

Adelotliyretis.

NORTH AMERICAN COLEOPTERA. 11

Juxta-sutural groove entire.

Antennje with second joint alone small Hicroi'hagii!^.

Antennse with joints two and three moniliform.

Entoiiioi>litlialiiin!>».

10. — Posterior coxal plates parallel or wider externally 11.

Posterior coxal plates narrower externally 12.

11. — Antennae slender, filiform.

Third joint not longer than second Xylobins.

Third joint much longer than second Hj'loHiares.

Antennae bi-serrate J, or bi-pectinate % Sarpeclon.

12. — Mandibles stout, rugose 13.

Mandibles slender, not rugose 14.

13. — Last ventral segment prolonged in a point Xeniafodes.

Last ventral segment obtuse at tip H.ypoeoelus.

14. — Prosternal sutures straight; lateral margin of thorax distinct 15.

Prosternal sutures arcuate; lateral margin almost obliterated 17.

15. — Clypeus very deeply sinuate each side SfliizopliiliiS.

Clypeus regularly arcuate in front 16.

16. — Coxal plates suddenly broader internally; last four joints of antennae

abruptly longer Epiplianis.

Coxal plates gradually broader internally.

Last three joints of antennae abruptly longer PKlegOii.

Outer joints of antennae shorter C'ryptostoiiia.

17. — Clypeus arcuate in front ; coxal plates abrujitly wider at inner third ; an-
tenna with joints 4-10 moniliform Aiielastes.

DENDROCHARIS Guerin.

Form cylindrical, rather robust ; antennae rather short, first joint moderately
elongate, second very short, third longer, joints four to ten strongly dentate,
eleventh oval, acute ; head large, deeply inserted, eyes slightly emarginate ; cly-
peus very little narrowed at base ; prothorax wider than long, lateral marginal
line entire ; prosternal sutures straight, propleural triangle wider than long, with
a deep and well defined gi-oove to receive the antennae along its outer border ;
mctasternum with an oblique groove on each side beginning at the posterior
margin of the middle coxae directed obliquely backward and to the outer side ;
episterna distinctly wider behind, the epimera not visible ; posterior coxal plates
broader externally ; legs moderately robust, the tibiae broader toward the tip ;
posterior tarsi shorter than the tibia, the first joint small, equal to the second,
joints 2-3-4 each with a rather long membranous lobe beneath, the fourth not
dilated nor enlarged, last joint as long as the preceding three; claws slightly
broader at base.

Regarding this geniigi Bonvouloir very ju.stly remarks that it pre-
sents so many strange characters that it is difficult to a.ssign it a place.
In the genera Gastraulacus and Temnillus the same metasternal
grooves are observed, but the structure of the tarsi is similar to that
of Agastocerus and Galba. A certain relationship also with Dro-
mjBolus must not be lost sight of.

GEO. H. HORN, M. D.

D. flavicoruis Guerin. — Form cyliudrical, moderately robust, attenuate
at posterior third only, dark brown, opaque, moderately densely clothed with
yellowish cinereous pubescence ; antennae yellowish in color,
scarcely passing the hind angles of the thorax ; head densely
roughly punctured, front rather flat, a distinct rounded de-
pression between the bases of the antennae ; clypeus very
little narrower at base, the anterior border truncate at mid-
dle ; thorax broader than long, sides nearly straight, very
little narrower in front, slightly arcuate at the anterior an-
gles, disc moderately convex, with a slightly marked line at
the middle of the base and on each side a short oblique im-
pressed line, surface rather densely rugose ; elytra narrower
at apical third, without traces of striae, but with feeble traces
of oblique impressions, surface densely rugose, but more
finely than the thorax ; prothorax beneath densely rugose,
the metasternum and abdomeu less coarsely rugose ; last ventral segment com-
pressed on each side terminating in an obtuse point. Length .32 - .48 inch ;
8-12 mm.

The only specimen I have ever seen of this species is in the cabinet
of Dr. LeConte, obtained by him from some European collection.
It seems to be excessively close to bombycina found in Columbia, S. A.,
and this in conjunction with the fact that forty-two years have elapsed
since its description without others having been found, makes me
look upon the species as rather doubtful.

Occurs at Savannah (Bonvouloir).

STETHOX Lee.

Form cylindrical, rather robust, slightly narrower behind ; antennae very little
longer than the head and thorax, compressed, diflFering in the two species in the
proportions of the joints; head convex, deeply inserted; clypeus very little nar-
rowed at base, much broader than the distance to the eyes, apical margin trun-
cate, or feebly emarginate ; prothorax wider than long; elytra parallel, narrowed
at apical fourth ; prosternum rather short in front of the coxae, the sutures
deeply impressed, distinctly arcuate (pectorosus), or very feebly arcuate (errans),
propleural triangle nearly equilateral, the antennal grooves marginal, deep, nar-
row, closed behind and with parallel sides ; metasternal episterna very narrow,
parallel; a slight longitudinal impression beginning at the outer side of the
coxae ; hind coxal plates broad and dilated internally ; legs moderate, tarsi fili-
form, the first joint as long or longer than the next four, fourth joint simple ;
claws simple ; last ventral segment more or less prolonged at apex.

With the typical species (pectorosus) above there would be no
difficulty in easily distinguishing the genus from almost every other
in the Eucnemine series by the strongly arcuate prosternal sutures,
but the second species shows a strong tendency to revert to the form
usual in the series. Excluding the prosternal sutures from considera-

NORTH AMERICAN COLEOPTERA. 13

tion the genus is closely related to Dromaeolus, from which it differs
ill the simple tarsi and very broad clypeal base. The eyes do not
narrow the antennal groove.

S. peotorosus Lee. — Form robust, cylindrical, slightly narrower behind,
brown or piceous. subopaque, pubescence extremely short and sparse ; antennae
not extending beyond the hind angles of the thorax, flattened, first joint stout,
as long as the next three, second small, partly concealed, third one and a half
times the length of the fourth, joints 4-10 gradually very little shorter, the outer
joints a little wider than long, eleventh oval longer than the tenth ; head con-
vex, coarsely and densely punctured ; clypeus twice as wide at base as the dis-
tance to the eyes, apex very slightly emarginate ; thorax a little longer than
wide, sides arcuate in front, straight and parallel posteriorly, hind angles rather
obtuse, not carinate, a slight depression along the lateral margin, disc convex,
sometimes slightly flattened along the middle with a shallow, but broad depres-
sion deeper posteriorly and sometimes smoother, surface densely and rather ru-
gosely punctured ; elytra striate, the intervals convex in their entire length,
densely rugosely punctured ; prosternum coarsely but very sparsely punctured,
the triangle more coarsely and densely; metasternum coarsely, but sparsely
punctured ; coxal plates and abdomen more finely and densely ; hind tarsi with
the first joint as long as the next four. Length .30 - 32 inch ; 7.5-8 mm.

As observed by Bonvouloir this species has considerable resem-
blance in form and sculpture to Hi/lochares nigricornU.

Occurs in Ohio, Illinois and Missouri. A specimen in my cabinet
was collected under the bark of Shellbark Hickory.

S. erraiis n. si). — Form cylindrical, slightly narrower at apical third, color
ferruginous brown, feebly shining, very distinctly clothed with short fulvous
pubescence; antenuie as long as the hind angles of the thorax, the first joint
stout, as long as the next three, second small partly concealed, but as long as the
fourth, third as long as the next two and more than twice as long as wide, joints
4-10 subequal in length, but gradually more slender, eleventh nearly as long as
the preceding two ; head convex, densely punctured, a distinct carina extending
from the base of the clypeus to the occiput ; clypeus very little narrowed at base,
not twice as wide as the distance to the eyes, apical margin truncate ; thorax a
little wider than long, sides arcuately narrowed in front, very slightly arcuate
posteriorly, the hind angles short, a distinct submarginal groove ; disc convex,
very slightly flattened at middle, a very vague median depressed line, surface
densely punctured, on the deflexed sides more sparsely ; elytra vaguely sub-
striate, the surface moderately densely subrugosely punctured ; prothorax be-
neath coarsely, but not densely punctured, the triangle more opaque ; metas-
ternum coarsely not densely punctured ; abdomen more finely and densely ; first
joint of hind tarsi three-fourths the length of the tibia and longer than the next
four joints. Length .28 inch ; 7 mm.

The charactei-s in which this species^differs from pectorosxis might
almost be considered generic but I prefer to consider them allowable
modifications within the genus rather than to increase the already

considerable number of feebly separated genera. The modifications
alluded to are in the very feebly arcuate prosternal sutures, the an-
tennae and the hind tarsi. In form and color this species resembles
Microrluujm impremcoUis, but the pubescence is more evident.
One specimen, Florida.

EIJC'K'EMIS Alireus.

Form oblong, moderately robust ; antennae passing very little the bind angles
of the thorax, first joint moderately long, second small, third longer than the
fourth, joints 4-10 transverse, dentate, the eleventh longer, oval and acute at
tip ; head deeply inserted, eyes oval, entire, not narrowing the antennal groove ;
clypeus distinctly narrowed at base {capucina), or scarcely so (americana), strongly
inflexed, the apical margin distinctly sinuate at middle {capucina), or broadly
emarginate {americana), front carinate ; prothorax broader than long, narrower
in front, hind angles slightly prolonged, not carinate; elytra obsoletely sub-
striate ; prosternal sutures straight, but deeply impressed ; propleural triangle
broad, the outer side a little longer than the basal, the antennal groove deep,
limited externally by the margin of the thorax ; metasternum with an impressed
line beginning at the outer side of the middle coxte and extending directly
backward nearly to the posterior margin and becoming gradually finer, another
elevated line extends from the humeral angle of the metasternum and is directed
obli((uely backwards and inwards ; metastcrnal episterna narrow and parallel ;
posterior coxal plates triangularly dilated ; legs rather short, tarsi slender, the
first joint of the posterior nearly as long as the next four together, the fourth
joint simple ; claws simjjle.

For the first time this genus as restricted by Bonvouloir is indi-
cated in our fauna. It resembles Deltometopus and Dromieolus in
many of its characters, but may be distinguished from either by the
metasternal characters and slender tarsi.

One species is known in our fauna.

E. aiiierioaua n. sp. — Piceous black, moderately shining, sparsely clothed
with short grayish pubescence, form oblong, slightly narrower posteriorly ; an-
tennje ferruginous brown, the first joint darker ; head convex, moderately densely
jiunctate, a distinct carina extending from the apical margin of the clyi^eus to the
occiput ; clypeus more coarsely punctate, very little narrowed at base and slightly
wider than the distance to the eyes ; thorax wider than long, narrower in front,
the sides feebly arcuate posteriorly, more so in front, disc convex, a slight de-
pression at middle posteriorly and feebly along the basal margin, surface rather
finely not densely punctate ; elytra vaguely substriate, the surface punctured
similarly to the thorax and somewhat rugose along the base, sutural stria fine and
entire ; body beneath rather coarsely but not densely punctured, the abdomen
rather more finely punctured ; last ventral segment obtuse at tip, a slight trans-
verse impression each side near the apical margin ; legs brownish. Length .24
inch ; 6 mm.

The specimen from which the above descri])ti()n has been drawn is
in my cabinet, from near Mt. tShasta, California. There is a second

NORTH AMERICAN COLEOPTERA. 15

specimen in the cabinet of Dr. LeConte somewhat smaller, the sides
of the thorax a little more oblique and the disc of thorax more
sparsely i)unctate ; this I am unwilling on the one specimen to sepa-
rate it with another name notwithstanding the fact that it is labeled
Kentucky.

E. amencana resembles capucina in form and color and seems to
differ only m the characters noted in the generic description.

DEIiTOMETOPUS Bonv.

Form elongate, moderately convex, gradually narrower posteriorly ; antennae
moderately elongate, shorter in the female ; head convex, rather deeply inserted ;
cly])eus narrower at base than the distance to the eye, the anterior border arcuate,
with a slight sinuation at middle ; prothorax as long as wide, diftering in form
in the two sexes; elytra gradually narrower to apex, striate; prosternal sutures
divergent, triangle of propleurse longer than wide, the antennal groove deep,
limited externally by the lateral margin, and not interrupted on the head by the
eyes; metasternal episterna nearly parallel, very slightly wider behind, the
epimera not visible ; hind coxal plates gradually, but not greatly dilated inter-
nally; last ventral segment obtuse ; legs rather short, first joint of hind tarsi as
long as the next three, the fourth slightly dilated, excavated above and slightly
lobed beneath, claws simple.

The differences between this genus and Dromseolus are rather
feeble. In the latter the antennal grooves are narrow and not much
than one-fourth the width of the base of the propleural triangle, while
in Deltometopus the grooves posteriorly are one-half the width of
the triangle.

Two species occur in our fauna.

Antennae not as long as half the body, pectinate in the % serrate 9 > tlie an-
tennal groove distinctly wider behind siiiicenioornis.

Antennae longer than half the body % , nearly half as long as body 9 , filiform
in both sexes, antennal grooves very broad, not narrowed in front, apparently
widest at middle rtifipes.

D. aniociiic'oriiis Say. — Form moderately elongate, gradually narrowed
behind, piceous, feebly shining, sparsely clothed with grayish pubescence ; an-
tennae not reaching the half of the body, piceous or with the second and third
joints testaceous in % , first joint rather stout, second small, third three-fourths
as long as the first, fourth triangular, broader and more acute '^ , joints 5-10
pectinate % , the branches longer than the joint and gradually longer externally,
the eleventh joint slender, longer than the branch of the tenth, joints 5-10 J
serrate, the tenth oval, acute, as long as the two preceding ; head densely punc-
tate, front slightly concave, the interocular carina interrupted at middle and
slightly turned downward to the base of the clypeus, but entirely absent in the
female ; thorax a little wider than long, narrower in front % with the sides
straight, slightly arcuate near the front angles ; in the female the thorax is widest
one-third behind the apex, the sides in front arcuate, posteriorly straight and

16 GEO. H. HORN, M. D.

slightly converging, disc convex, moderately densely punctate, hind angles not
carinate ; elytra striate, intervals slightly convex, rather densely rugosely punc-
tate ; body beneath coarsely, but not densely punctate ; abdomen more finely and
closely ; legs ferruginous, brown. Length .12 - .18 inch ; 3 - 4.5 mm.

The males are usually smaller and more slender than the females
and the form is so obviously different that it is not remarkable that
Say described them as distinct.

In distribution the sjDecies is widely diffused, occurrmg from the
N. E. States to Texas.

I have examined the type of D. ereptus Bon v. in the cabinet of
my friend Salle, and find that it is merely an avKsnicornis with the
branch broken from the fifth joint of the antennae. May not Euc-
nemis monilicornis Mann, be the female of amcenicornw ?

Closely related to ammnicornis is foveolatus Guer. from Mexico.
Bonvouloir appears to have seen but one 9 in which there were two
transverse foveae on the disc of the thorax. These seem not to be
always present and therefore of no value in separating the two species.
I find, however, that the marginal sulcus is quite well marked in
the 9 and will serve to distinguish both sexes from amcenicornis.

D. riifipeN Mels. — Form oblong, rather slender % , stouter 9 , brown or pi-
ceous, slightly shiuing, sparsely clothed with cinereous pubescence ; antennae
paler brown, two-thirds the length of the body and slender % , less than half the
length of body and stouter 9 > joint second shorter, but equal to the fourth, third
nearly as long as the next two, joints 5-10 slender, gradually longer, the elev-
enth one and a half times as long as the tenth ; in the female joints 4-10 are
nearly equal in length, very little longer than wide, the eleventh nearly as long
as the two preceding ; head convex, coarsely and deeply punctate, front rather
deeply depressed above the base of the clypeus, the fi-ontal carina broadly inter-
rupted at middle ; clypeus very coarsely punctate, very narrow at base, less than
half the distance to the eyes ; thorax slightly broader than long, narrower in
front, but less so in the female, sides posteriorly straight, in front arcuate, hind
angles very little prolonged, not carinate ; disc convex, moderately coarsely and
closely punctate, a very slight median line 9 not evident in the % ; elytra grad-
ually narrower at apical third, the disc vaguely substriate near the base, surface
more finely and sparsely punctate than the thorax ; body beneath coarsely and
closely punctate ; legs rufo-ferruginous. Length .14 % - .22 9 inch ; 3.5 - 5.5 mm.

Since my attention has been called to this species by the studies
preliminary to the present essay, it has given me nearly as much
trouble as my notes concerning it ajDpear to have caused Bonvouloir.

In comparing this species with amoenicornis two very striking dif-
ferences have been observed ; first, in the form of the antennae and
second in the antennal grooves. The unusual length of the antennse
% has, however, a parallel in falla.r, a Brazilian species, and may

and may therefore be dismissed from further consideration. In all
the species of Deltometopus the antennal groove is distinctly wider
behind. In rufipes the groove is fully as wide as the small pro-
pleural triangle and not wider behind but, if anything, widest oppo-
site the middle of the propleural triangle. The width of the groove
is such that the outer apical angle of the prosternum is cut off by it.
Two specimens, Canada.

D ROM .1:01.1 S Kies.
Form slender, subcylindrical, usually narrower posteriorly ; antennte filiform,
or very feebly serrate, usually more slender to the tip ; head convex, deeply in-
serted . eyes convex, not encroaching upon the antennal groove ; clypeus narrowed
at base, inflexed, the apical margin usually truncate at middle, sinuate each side ;
mandibles robust, the exposed surface large and rugose ; prothorax variable in
form, usually not longer than wide; prosternal sutures distinct, usually deep,
slightly divergent, the propleural triangle always longer than wide at base, the
antennal gi-ooves narrow, parallel, open behind, usually deep and sharply limited,
rarely (hasalis and nitens) shallow and not limited internally; metasternal epis-
terna parallel, the epimera invisible ; hind coxal plates gradually wider inter-
nally ; legs moderate ; hind tarsi with the first joint variable, at least as long as
the next three joints, the fourth excavate emarginate above and slightly lobed
beneath ; claws simple.

ThLs genus and Fornax are very closely related, the only constant
difference being that the larger eyes of the latter narrow the antennal
groove at its entrance on the head. This character is, however, diffi-
cult to realize at times, so that I have doubted whether salsus should
really be retained in the present genus.

This genus Ls represented on both sides of the continent, the sj^ecies
are as follows :

Interocular carina entire, extending across the base of the clypeus.

ealirorniciis.

Interocular carina interrupted at middle 2.

2. — Clypeus at base half as broad as the apical margin 3.

Clypeus at base very narrow 8.

3. — Body above brown 4.

Body above black 5.

4.— Mesopleura- punctured at base and externally (second joint of antennae

shorter than the fourth Bonv.) sejunctus.

Mesopleurae punctured over the entire surface ; second joint of antenuaj

longer than the fourth i^alsus.

5. — Marginal grooves of thorax shallow, not sharply limited internally 6.

Marginal grooves deep, sharply limited 7.

6. — Propleural triangle fully twice as long as wide; upper surface shining,

pubescence very sparse and inconspicuous uitens.

Propleural triangle not twice as long as wide ; upper surface opaque, elytra
with paler pubescence at basal third basalis

7. — Elytra deeplj' striate, surface roughly sculptured, the punctuatiou of the
abdomen coarse, the pubescence inconspicuous J^ti'iaf US.

Elytra faintly striate, punctuation not rough, the abdomen rather densely
and finely punctured, the pubescence conspicuous Harriiigtoiii.

Elytra without strife, punctuation not rough, the abdomen coarsely punc-

Color piceous, antennae half as long as the body, propleural triangle not
twice as long as wide; elytra not striate piii^illiis.

D. califoruicus Bonv. — Form oblong, moderately robust, color nearly
black, subopacxue, sparsely clothed with short brownish pubescence; antennae
not extending beyond the hind angles of the thorax, filiform and rather com-
pact, second joint distinctly longer than the fourth, third as long as the next
two, fourth and fifth very little longer than wide, 6-11 gradually longer ; head
convex, the punctuation dense, slightly rugose, but not very coarse, the inter-
ocular carina extending distinctly across the base of the clypeus ; clypeus nar-
rower at base than half the apex and equal to half the distance to the eyes ;
thorax as long as wide, the sides posteriorly parallel, or feebly arcuate, anteriorly
arcuately narrowed to the front, disc convex, a very feebly impressed median
line almost obsolete in front, surface coarsely, densely and subrugosely punctured ;
elytra distinctly striate, the intervals feebly convex, densely subrugosely punc-
tured, but less coarsely than the thorax ; prosternum coarsely, but sparsely punc-
tate, the sutures straight, open in front, the triangle one and a half times as long
on the outer side as wide at base ; antennal grooves deep, sharply limited ; metas-
ternum and abdomen coarsely and moderately densely punctured, last ventral
segment not prolonged in a point ; legs brownish ; tarsal claws simple. Length
.36 - .40 inch ; 9 - 10 mm.

This species ha.s the most robust faeies of any in our fauna and
may be at once known by its subopaque bhick color and the entire
interocular carina. By the table given by Bonvouloir it is plainly
related to ischiodontoides, from which it differs in color and form of
its thorax. In comparing the above description with that by Bonvou-
loir sevei'al unimportant differences will be observed. The type is
in my cabinet.

Two specimens, California.

D. sejuuetiis Bonv. — Form straight, slightly attenuate posteriorly, reddish
brown, clothed with short yellowish pubescence ; antennse slender, ferruginous,
not as long as half the body, second joint shorter than the fourth, third distinctly
longer than the fourth, joints 5 - 10 longer than wide, gradually longer, the elev-
enth one-half longer than the tenth ; head convex, punctuation fine, rather dense,
scarcely rugose, interocular carina broadly interrupted at middle ; clypeus at base
half as wide as the apex ; thorax a little wider than long, sides posteriorly straight
and parallel, anteriorly feebly arcuate, disc convex, a small fossa on each side of
the middle of base, a feeble median line near the base which beconies obliterated,
and is again evident in front without, however, reaching the middle, the i)unctua-
tion not coarse nor very den.se, slightly rugose near the sides ; elytra finely striate,

NORTH AMERICAN COLEOPTERA. 19

strise finely, moderately densely punctate ; body beneath finely and densely punc-
tate, a little coarser on the prosternum ; antennal groove sharply defined, not
wider posteriorly, the propleural triangle with the outer side twice as long as the
base ; mesopleurfc with few punctures at base and externally ; legs and tarsi fer-
ruginous. Length .36 inch ; 9 mm.

I have in my collection a specimen which I think must be referred
to this species, but I do not observe the median depressions of the
thorax mentioned in the above description. These are, however,
faint in the type and are a variable quantity, so that I do not attach
any importance to their absence. The facies of the species is very
deceptive and not unlike Fornax bicohi: In addition to the charac-
ters given by Bonvouloir I observe that the last joint of the tarsi is
extremely slender and the claws very small, feebly curved and sim-
ple. My specimen is .42 inch ; 10.5 mm. long.

Collected near Caiiandaigua, New York, by I'abbe de Marseul,
and on Long Island by Mr. Wm. Jiilichs.

D. salens Bonv. — "This species is .so like the preceding that I hesitated a
long time before separating it ; so that it will be neces.sary to mention only the
ditferential characters. The pubescence is more silken and of a golden reddish
color ; the head more coar.sely, densely and roughly punctured ; the clyiieus wider
at base and the apex is not twice as wide ; the front is slightly impre.ssed at mid-
dle anteriorly ; the thorax is very nearly as long as wide, the sides slightly sinuate,
the punctuation coarser, denser and more rugose, the base on each side of middle
more depressed and with a small median gi-oove, which is interrupted, attaining
the middle in front ; the intervals of the strise are distinctly rugo.se tramsversely ;
the mesopleurte are entirely punctured with coarse impressed punctures. Length
.38 inch ; 9.5 mm.

The al)ove is nearly a literal translation of Bonvouloir's remarks,
which I have thought advisable to repeat in order that the preceding
species may be more readily known. I observe, hoAvever, that the
second joint of the antennae is much longer than the fourth, the
third as long as the next two, the fourth is short, not as long as wdde,
joints 5 - 10 gradually very little longer, eleventh longer and acute
at tip.

I am indebted to my friend Salle for the privilege of examining
the type of this species, collected by him in Louisiana.

D. nitens n. sp. — Form oblong, parallel, narrowed only at apical third, color
black, moderately shining, the pubescence extremely short and inconsiiicuous ;
antennae piceous, extending slightly beyond the hind angles of the thorax, slender,
scarcely at all serrate, second joint as long as the fourth, third as long as the next
two, 4 and 5 equal, 6-8 equal, distinctly longei-, 9 and 10 equal, scarcely longer
than 4 and 5, eleventh one and a half times as long as the tenth ; head convex,
without interocular carina, moderately densely, but not roughly punctured ; cly-

20 GEO. H. HORN, M. D.

peus broad at base, equal to half the apex, and nearly as wide as the distance to
the eyes ; thorax a little longer than wide, sides posteriorly nearly straight, arcu-
ate at apical third, disc moderately convex, at base a moderately broad triangular
depression, at the bottom of which the median line is distinctly impressed and
extends forward to the middle becoming gradually obsolete, surface moderately
densely punctate, distinctly rugose at the sides ; elytra faintly striate at the base
and sides, the surface more finely and sparsely punctate than the thorax ; body
beneath moderately densely punctate, more sparsely and coarsely in front ; pro-
pleural triangle twice as long on the outer side as wide at base, the antennal
groove shallow, deeper in front, not sharply limited internally ; mesopleurte
sparsely j)unctate in front and externally ; legs piceous, tarsi brown. Length .38
inch ; 9.5 mm.

This species and the next are remarkable in having the antennal
grooves badly limited on their inner side. The present species is
more shining and with almost invisible pubescence. In general ap-
pearance it resembles cyluidricol/is, but is larger and less convex.

Occurs in Oregon and Washington Territory.

D. basalis Lcc. — Form moderately elongate, slightly attenuate posteriorly,
black, subopaque, clothed with very short brown pubescence, but with the basal
third of the elytra more densely clothed with longer, yellowish cinereous pubes-
cence ; antennse dark brown, slender, filiform, slightly longer thau to the hind
angles of the thorax, second joint as long as the fourth, third a little longer than
the next two, four to ten gradually longer, eleventh nearly as long as the two pre-
ceding ; head convex, densely and rather roughly punctured ; clyi^eus as broad at
base as half the apex and nearly as wide as the distance to the eyes ; thorax as
broad as long, sides posteriorly straight, arcuately nari'owing at apical third, disc
moderately convex, a vague depression at the middle of the base, median line
feebly impressed extending forward nearly to the middle, surface very densely
punctured and at the sides rugose; elytra substriate, the surface moderately
densely punctured, more finely than on the thorax ; body beneath more sparsely
and more finely punctured than above, the punctures of the prosternum coarser ;
triangle of the propleurse not twice as long as wide at base, the antennal groove
shallow and scarcely at all limited internally ; mesopleurse sparsely punctate ; legs
brown, the femora darker. Length .24 - .34 inch ; 6 - 8.5 mm.

The antennal grooves are even more shallow than in nitens, a char-
acter which seems to have been entirely overlooked by Bonvouloir.
The paler pubescence forms a broad band at the base of the elytra
and becomes gradually wider externally.

The very shallow and feebly limited antennal grooves of these two
species seem to indicate some relationship with those species of Ne-
matodes in which there is a beginning of an antennal groove near the
front angle of the thorax.

This species occurs in the mountainous regions of Northern Cali-
fornia and Nevada.

NORTH AMERICAN COLEOPTERA. 21

D. striatus Lee. — Form moderati'ly elongate, gradually narrower posteriorly,
black, subopaque, sparsely clothed with sliort yellowish gray pubescence, some-
times more conspicuous on the thorax and base of elytra ; antennae not passing
the hind angles of the thorax, slender, second joint longer than the fourth, third
equal to the next two, joints four to ten gradually longer, eleventh one and a half
times the length of the tenth ; head coarsely and rather roughly punctured, the
interocular carina not reaching the clype\is ; the latter at base half as wide as at
apex, nearly as wide as to the eyes ; thorax distinctly longer than wide, sides par-
allel, or very slightly arcuate, in front arcuately narrowing to the apex, disc mod-
erately convex, a distinct depression at the middle of the base, in which the
median line is very deeply impressed one-third toward the apex, surface densely
punctured, more roughly toward the sides ; elytra deeply striate, the intervals
slightly convex, rather coarsely and roughly punctured ; prosternum moderately
not densely punctured ; the propleural triangle twice as wide as long at base, the
antennal groove deep, narrow, sharply limited ; mesopleurse sparsely punctate ;
metasternum very coarsely sparsely punctate ; abdomen with a coarse not dense
punctuation, the pubescence very sparse ; legs piceous, the tibise and tarsi some-
what paler. Length .2'2 - .34 inch ; 5.5 - 8.5 mm.

Tliis species is rather more robust, the sculpture more rugose than
either of the next two species and differs also in the elytra much
more deeply striate.

It seems to be the analogue in the Atlantic region of californicMs
in the Pacific as cyllndricollis is of niteni< and Harringtoni of basalis.

Occurs from New York to Florida, but is more essentially a

Southern species.

D. Harringtoni n. sp. — Form elongate, moderately convex, slightly nar-
rower posteriorly, black, shining, sparsely clothed with cinereous yellow pubes-
cence, more conspicuous on the thorax and base of elytra ; antennge slender,
passing slightly the hind angles of the thorax, feebly subserrate, second joint as
long as the fourth, third not quite as long as the next two, joints four to ten
longer than wide and gradually more elongate, eleventh one-half longer than
the tenth ; head convex, densely punctured, a distinct transverse frontal impres-
sion, interocular carina broadly interrupted at middle ; clypeus as wide at base
as half the apex and wider than half the distance to the eyes ; thorax longer
than wide, sides posteriorly straight, but slightly convergent, anteriorly slightly
arcuate, disc moderately convex, a slight triangular depression posteriorly, the
median line finely impressed one-third to the front, surface not coarsely nor
densely punctured at middle, more densely at the sides, but not rugose ; elytra
substriate, the punctuation a little coarser and closer than on the middle of the
thorax ; prosternum rather closely finely punctate, the triangle more coarsely,
its outer side not twice as long as base, the antennal groove deep, narrow and
sharply limited ; mesopleurse coarsely sparsely punctate ; metasternum coarsely
punctured, the punctuation somewhat longitudinally strigose ; abdomen densely
rather finely punctate, the pubescence rather dense; legs i)iceous. Length .22-
.24 inch ; 5.5 - 6 mm.

The elytral sculpture is about intermediate between cyHinlricoUh

and driatus, otherwise the sculpture of the surface resembles the for-

mer, but is finer. The median basal depression is smaller than either
of those and the median line is not deeply impressed. The punctua-
tion of the abdomen is much finer and its pubescence denser, so
that in certain lights it obscures the punctuation. I have no doubt
but that this species is mixed in most collections with striatus as a
smoother variety.

I have named this species in comj^liment to Mr. W. H. Harring-
ton, of Ottawa, to whom I am indebted for the kind loan of mate-
rial on several occasions.

Occurs in New York and Canada.

D. cyliiidrioolli^ Say. — Form elongate, moderately convex, slightly nar-
rower posteriorly, black, shining, sparsely clothed with very inconspicuous yel-
lowish hair ; antennse not extending beyond the hind angles of the thorax,
piceous, subserrate, second joint longer than the fourth, third as long as the
next two, joints four to ten longer than wide and gradually longer, eleventh
one-half longer than the tenth ; head convex, coarsely and densely punctured,

as at apex, but not more than half the distance to the eyes ; thorax longer than
wide, sides straight and parallel posteriorly, obliquely convergent at apical third,
disc moderately convex, a median depression at base, the median line very deeply
impressed one-third from the base to the front, surface not very densely punc-
tured at middle, more densely at the sides, but scarcely rugose ; elytra with the
sutural stria extending two-thirds from apex to base, the surface otherwise mod-
erately coarsely but not very densely punctured and not rugose ; prosternum

This species is readily known by the entire obliteration of the
elytral striae except the sutural.
Occurs from Canada to Georgia.

of the propleurse almost twice as long on the outer edge as at base ; legs bright
reddish brown. Length .30 inch ; 7.5 mm.

This species is also unknown to nie in nature. From the descrip-
tion it seems to resemble very closely Fornax hacUm.

Collected at Canandaigua, New York, by I'abbe de Marseul.

D. pusillu!i» u. sp. — Form oblong, rather slender, distinctly narrower behind,
piceous black, moderately shining, sparsely clothed with short brownish pubes-
cence ; antennse ferruginous, a little darker externally, as long as half the body,
second joint a little shorter than the fourth, third a little longer, joints four to
ten feebly serrate, all longer than wide, gradually longer, eleventh more slender,
nearly as long as the preceding two ; head convex, moderately densely punctate,
interocular carina interrupted at middle ; clypeus very narrow at base, less than
one-fourth the apex and a third the distance to the eyes ; thorax broader than
long, sides feebly sinuate and gradually narrowed from the base to the apex,
disc convex, a slight fovea each side of middle of base, median line a little
smoother posteriorly and slightly elevated, surface coarsely not densely punc-
tured at middle, more densely and roughly at the sides ; elytra with a fine su-
tural stria and vague traces of strise in the basal depression, the surface a little
less densely and less coarsely punctured than the thorax ; body beneath rather
coarsely and moderately densely punctured, outer side of triangle of propleurse
one and a half times the length of the base ; antenna! groove deep, sharply
limited, not more than a third the width of the triangle ; mesopleurfe very
sparsely punctured ; tibise and tarsi ferruginous, femora darker. Length .14
inch ; 3.5 mm.

This little species has a facies totally different from all the Dro-
mseolus in our fauna. It is of the size and form of the male of
Deltometopus amoeniconus, and it would have been placed in that
genus in relation with the Brazilian fallax, except that the antennal
grooves are as in Dromgeolus. The triangle of the propleurae is not,
however, as long as is usual in the latter genus. Considering the
extremely close relationship of the genera Deltometopus, Dromaeolus
and Fornax, this species is better placed in the second. It is much
the smallest species in our series and is equaled in this respect by
dllufipes and Funckli, both of which belong to the series with the
prosternal sutures closed in front. By the table given by Bonvou-
loir the species would be placed near f rater and propinquus, both of
which are comparatively large species and differ otherwise.

A specimen, female, in the cabinet of Dr. LeConte has the thorax
larger, that is, the sides are less narrowed to the front and more ar
cuate, differing, in fact, from the male as the two sexes of Deltome-
topus amoenicornii difier.

One specimen, S , Northern Illinois, kindly given me by Mr.
Fred. Blanchard, a 9 in cabinet of Dr. LeConte from Texas.

FORNAX Cast.

Form variable, but usually oblong, and more or less cylindrical ; antennae
variable in length, usually serrate ; head convex, deeply inserted, the eyes mod-
erately large and encroaching upon that part of the antennal groove extending
on the head ; clypeus narrowed at base, but variably, the apical margin truncate
at middle, sinuate each side ; mandibles presenting a rather broad rugose face ;
prothorax of variable form, usually narrowed in front, the hind angles more or
less prolonged; prosterual sutures distinct, slightly divergent, the triangle
broad, usually as broad at base as long, the antennal grooves deep, sharply limited
on each side, much narrower than the triangle, usually parallel (wider in front
in infelix) ; elytra striate ; metasternal episterna moderate, parallel, the epimera
not visible ; hind coxal plates widely dilated internally ; last ventral segment
obtuse ; tarsi filiform, the first joint of the posterior pair as long as all the others,
the fourth broader, excavate above and slightly lobed beneath ; claws toothed
in the larger species, simple or slightly broader in the smaller.

The species of this genus are confined to the Atlantic region of
our fauna, and are of rather homogeneous aspect. It is very closely
related to Dromasolus, and separated by characters which seem in-
clined to be evanescent. The only species possessing remarkable
characters is infelix, these are alluded to in the description.

The characters of the following table will readily distinguish our
species :

Second joint of antennse as long, or very nearly as the fourth 2.

Second joint small, not half as long as the fourth 3.

2. — Front without trace of interocular carina ; color pale castaneous-.basalis.

Front transversely carinate between the eyes ;" color piceous Horiiii.

3. — Epipleurae not grooved 4.

EpipleursE grooved and smooth 5.

4. — Interocular carina entire, color piceous; species small ealeeattis.

Interocular carina wanting; species large 6.

5. — Antennae slender, not serrate ; interocular carina extending slightly on the

base of the clypeus bicolor.

6. — Lateral margin of thorax single.

Antennae serrate on joints 4-8, the last three more slender and not ser-
rate inolestus.

Antennae serrate on joints 4 -10, the last joint alone slender.

Lateral margin of thorax double.

Antennae a little shorter than half the body and feebly serrate. .iiiftli-X.

F. badius Mels. — Form moderately elongate, somewhat narrower posteri-
orly, castaneous brown, feebly shining, clothed with short fulvous pubescence ;
antennae slender, a little longer than the head and thorax, first joint moderately
stout, slightly arcuate, as long as the three following, second a little longer than
the fourth, third nearly as long as the next two, fourth a little shorter than the
fifth, joints 5-10 nearly equal, eleventh a little longer; head convex, with a
moderate, but dense punctuation ; clypeus half as wide at base as at apex, the

base about equal to the distance to the eyes ; thorax a little longer than wide,
slightly narrowed in front, the sides nearly straight, slightly arcuate in front,
disc convex, moderately, coarsely and densely punctate ; elytra finely striate, the
intervals flat, moderately densely punctate, slightly rugose at base ; body be-
neath moderately densely punctured, the punctuation finer than above ; an-
tennal groove deep, sharply limited ; last ventral segment acute at apex ; claws
broader at base, but not toothed. Length .32 - .44 inch ; 8-11 mm.

This species is well known to nearly all collectors. The larva has
been found by me in decaying oak. By the great kindness of my
friend Salle, I have examined the actual type of Dromseolus novitius
Bonv. and find that it is merely a darker form of the present sjDecies.

Occurs from Pennsylvania to Illinois and Louisiana.

F. Ilornii Bonv. — Form oblong, moderately robust, piceous, or nearly black,
sparsely clothed with short fulvous pubescence ; antenufe brownish, extending
a little beyond the hind angles of the thorax, very feebly serrate, second joint
as long as the fourth, third a little longer, joints 4-11 gradually a very little
longer ; head convex, coarsely and densely punctured, a distinct frontal carina
between the bases of the auteunse ; clypeus at base less than a third the width
of the apex and less than half the distance to the eyes ; thorax as long as wide,
sides posteriorly parallel, anteriorly arcuately narrowing to the front, disc con-
vex, coarsely and densely punctured, a slight depression at the middle of the
base ; elytra striate, faintly at middle, more deeply at the sides, densely subru-
gosely punctate ; body beneath rather densely punctate ; antennal groove deep,
sharply limited ; posterior coxal plate rather abruptly broader at middle ; last
ventral segment oval at tip ; legs ferruginous ; claws simple. Length .28 - 32
inch ; 7 - 8 mm.

This species resembles calceatvs, but is usually more robust and larger,
the punctuation finer and the second joint of the antennae shorter.

In his description of this species in the concluding paragraph
(p. 893) Bonvouloir speaks of F. basalw Lee. when he plainly refers
to this species. He also quotes the locality " California" in error.

Occurs in Canada and Kentucky.

F. ealceatus Say. — -Form oblong, moderately convex, dark brown or pice-
ous, feebly shining, sparsely clothed with short yellowish pubescence; antenufe
nearly half as long as the body, slender, second joint shorter than the fourth,
joints 4-11 gradually slightly longer; head coarsely, deeply and roughly punc-
tured, a small, smooth longitudinal space on the front, a distinct transverse
carina between the bases of the antennse ; clypeus very narrow at base, scarcely
a fourth either of its apex or the distance to the eyes ; thorax longer than wide,
distinctly narrower in front, sides posteriorly straight, arcuate at apical third,
disc convex, a slight median depression at base, surface coarsely, densely and
roughly punctured ; elj'tra narrowed at apical third, faintly striate, surface

26 GEO. H. HORN, M. D.

In this species the interocular carina is more distinct than in
Hornii, and the posterior coxal plates gradually not al)rui)tly wider,
these characters with the smaller second joint of the antennae and
the coarser sculpture will readily distinguish the two.

Occurs in Canada and Massachusetts.

F. molestus Bouv. — Oblong, moderately elougate, convex, very little nar-
rowed behind, dark reddisli brown, subopaquc, sparsely clothed with fulvous
pubescence ; antennse passing very slightly the hind angles of the thorax, second
joint small, 3-8 dentate, 9-10 more slender and not dentate, eleventh longer
and filiform ; head coarsely, densely and roughly punctured, without longitu-
dinal or interocular carinas ; clypeus broad at base, nearly twice the distance to
the eyes; thorax a little wider than long, sides subparallel and straight behind,
arcuate and narrowed to the front anteriorly, disc convex, a median longitudinal
impression extending from the base to the middle, also two small impressed
points in front of the scutellum, hind angles short, obtuse ; surface coarsely,
densely and roughly punctured ; elytra slightly broader behind the middle, then
arcuately narrowed to the apex, deeply striate, the intervals convex, densely,
rather finely punctate and distinctly rugose ; mesopleurse rather finely and mod-
erately densely punctured over the entire surface ; legs ferruginous, claws toothed
at base. Length .52 inch ; 13 mm.

This species is unknown to me. It is evidently very like orchesides,
but has the elytra a little broader behind the middle, the antennae
differently formed, and the clypeus at base broader.

The locality indicated by Bonvouloir is simply North America.

F. orcliesirtes Newm. — Form oblong, moderately elougate, slightly nar-
rower behind, convex, ferruginous to piceous, feebly shining, surface clothed
with very short yellowish pubescence ; antenna? slightly compressed, more slen-
der externally, extending a little beyond the hind angles of the thorax, second
joint small, third not as long as the next two, joints three to ten serrate, the
eleventh slender and longer ; head convex, coarsely and densely punctured ;
clyi^eus at base a little broader than the .distance to the eyes ; thorax as long as
wide, sides posteriorly feebly arcuate, anteriorly obliquely narrowed to the front,
disc convex, the sides suddenly deflexed in front, a distinct median impression
at basal half, and on the basal margin each side of the scutellum a small fovea,
surface coarsely and densely punctured, hind angles acute, very little prolonged ;
elytra distinctly striate, the intervals slightly convex, the punctuation finer than
on the thorax, dense, slightly rugose at base, epipleurfe flat, roughly punctate ;
punctuation of the under side of body a little finer than on the elytra and rather
dense ; propleural triangle more opaque, the inner side and base equal ; meso-
pleurse sparsely punctate on basal half, nearly smooth in front ; hind coxal plate
gradually but much dilated internally; last ventral segments obtuse; claws
broadly toothed at base. Length .40 - .68 inch ; 10-17 mm.

This is the largest in our fauna and one of the largest in the entire
genus. It varies in size as well as in color, smaller specimens resem-
bling, superficially, the next species.

Occurs in Canada, the New England and Middle States.

F. bioolor Mels. — Oblong, moderately elongate, slightly narrower poste-
riorly ; ferruginous brown, feebly shining, the thorax more opaque, sparsely
clothed with short fulvous pubescence ; antennte slender, filiform, not at all den-
tate, nearly as long as half the body, joint second small, third one and a half
times the length of the fourth, joints four to ten gradually longer; head convex,
coarsely, densely and rugosely punctured, a slight depression above the base of
the clypeus, the interocular carina extending slightly on the base of the clypeus ; '
the latter very little narrowed at base and wider than the distance to the eyes ;
thorax with the width and length about equal, the sides feebly arcuate and nar-
rowing at apical third, hind angles scarcely prolonged, disc convex, sides strongly
deflexed in front, a feeble median impression posteriorly, surface densely punc-
tate, slightly opaque and rugose ; elytra striate, intervals slightly convex, densely
rather finely punctate and slightly rugose, epipleurse smooth, longitudinally ex-
cavated ; body beneath and legs paler than above, the punctuation moderately
dense and coarser in front ; mesopleur?e sparsely punctate in posterior half,
nearly smooth in front ; hind coxal plates gradually but much broader internally,
the free edge angulate ; claws broadly toothed at base. Length .32 - .46 inch ;
8-11.5 mm.

This species resembles orchesides in form, but may be known by
the slender antennae and the smooth sulcate epipleurse. This species
is without doubt the same as that subsequently described by Chev-
rolat as luridus. The information given by me to Bonvouloir that
bicolor was synonymous with orchesides was erroneous, from the fact
that the type of LeConte's description of bicolor was an orchesides.
Since that time the type of Melsheimer has been seen, and is the
species above described.

Occurs from the Middle States southward, and, according to Bon-
vouloir, in Cuba.

F. iiifolix n. sp. — Form subcylindrical, parallel, very obtuse in front, nar-
rower only at apical third, color ferruginous brown, subopaque, sparsely clothed
with short yellowish pubescence ; antennse paler, slender, nearly as long as half
the body, feebly serrate, joint second small, third a little longer than the fourth,
joints four to eleven gradually longer; head convex, coarsely densely and
roughly punctured, without trace of interocular carina; clypeus slightly nar-
rowed at base, but not broader than the distance to the eyes ; thorax very dis-
tinctly broader than long, sides posteriorly feebly arcuate but not convergent,
rounded near the front angles, disc convex, coarsely, densely and roughly punc-
tured, a vague depression each side of the base, hind angles slightly prolonged,
not acute, lateral margin distinctly double from apex two-thirds to base ; elytra
striate, intervals slightly convex, moderately densely punctate and quite rough
near the base, epipleurse roughly punctate, not sulcate ; prosternum shining,
punctuation coarse but distant, the triangle with inner side shorter than the
base, surf^ice densely, coarsely punctured ; antennal groove very deep and smooth,
open posteriorly, very distinctly wider in front ; mesopleurte moderately, densely,
finely punctate in anterior half, very smooth posteriorly ; metasternum and ab-
domen moderately, densely punctate ; hind coxal plate gradually wider inter-
nally, the free angle rounded ; claws broadly toothed at base. Length .36 inch ;
9 mm.

This species has an entirely different facies from any other in our
fauna, it in fact resembles a very large Microrhagm impressicollis, and
from several rather odd characters which it possesses has given me
considerable trouble to arrive at a conclusion regarding its generic
position. In the first place the eyes do not so much encroach upon
the antennal sulcus as is usual in the other species, while the sulcus
is not so free as in Dromseolus. The sulcus is very decidedly wider
in front. Finally, the lateral margin of the thorax is double in its
anterior two-thirds. This double margin is not at all of the form
described for Diaretus. After leaving the species for very nearly the
final study of the present essay, I have concluded that it is better to
consider it a Fornax than to make a new generic name.

Occurs in Florida.

PHAENOCERl S Bonv.

Form obloiifi, very slijfhtly depressed ; antenuge shorter thau the head and tho-
rax, gradually clavate ; head convex, deeply inserted, the eyes oval entire, dis-
tinctly encroaching upon the antennal groove ; clypeus broad at base, as wide as
the distance to the eyes, apical margin arcuate ; prothorax gradually narrowed
in front, very little wider than long; scutellum oval; elytra distinctly striate;
prosternal strife rather deep, straight, divergent, the propleural triangle a little
longer than wide at base, the antennal groove deep, sharply limited on each side
and open behind ; metasternal episterna narrow, wider behind, the epiniera not
visible ; hind coxal plates gradually wider internally ; legs moderate.

The unique before me is in very bad state of preservation, being
entirely deprived of tarsi, but after a renewed study, thirteen years
having elapsed since my original description I can see no reason for
changing the generic position of the species. The flattened clavate
form of the antennae leaves but little choice of position, but were the
antenna? slender there could be no hesitation in placing it in Fornax,

One species is known in our fauna.

P. aiiierioanu»$ Horn. — Form oblong, slightly depressed, black, feebly
shining, sparsely clothed with very short black pubescence ; antenute dark
brown, scarcely reaching the hind angles of the thorax, gradually clavate, first
joint short, second and third equal in length, but distinctly longer than wide,
fourth and fifth equal, a little longer than the third, six to ten broader thau long,
and gradually wider, eleventh narrower oval ; head coarsely, densely punctured ;
thorax a little wider than long, sides gradually narrowing to the front and very
slightly arcuate, disc convex, a vague depression at middle of base and a shallow,
broad depression near the lateral margin, surface densely and coarsely punctured ;
elytra parallel, narrowed at apical third, surface striate, intervals flat, densely
punctate ; prosternum coarsely but sparsely punctured, more shining, the triangle
more densely and opaque ; metasterniim coarsely, sparsely punctate ; abdomen
densely and much more finely. Length .30 inch ; 7.5 mm.

111 form this species resembles a small Fornax orcheddes, but is
much more depressed.

One specimen, Vancouver.

ADELOTHYREUS Bonv.

Form elongate, narrower posteriorly ; antennae half the length of the body,
second joint very small, third as long as the next two, joints four to ten gradu-
ally shorter and more strongly serrate, joint eleven elongate oval ; episterna nar-
row at base; propectus with a short juxta-sutural groove, limited externally in
front by a feeble carina ; lateral supplementary carinse distinct, the posterior very
long, the anterior short and directed arcuately downward ; posterior coxal plates
nearly parallel ; tarsi slender, the fourth joint slightly dilated and excavated
above, beneath very feebly lobed, the first joint of the posterior tarsi as long as
the next three ; claws very slightly broader at base.

This genus has all the essential characters of Microrhagus, except-
ing that the juxta-sutural groove is here merely feebly indicated in
front, while in that genus the groove Ls entire and limited externally
by a well defined carina. It Is, however, probable that this character
may not. long remain valid, as it will be seen that in M. humeralis the
outer carina of the groove is obliterated posteriorly, and in that and
Bonvouloiri the coxal plates are parallel, while the tarsal structure
also more nearly resembles Adelothyreus.

One species is known in our fauna.

A. Dejeani Bonv. — Slender, elongate, gradually narrower posteriorly, pice-
ous, feebly shining, sparsely clothed with very short yellowish cinereous pubes-
cence ; head deusely, roughly punctate ; epistoma at base narrower than the
space between it and the eye ; antenna? piceous, joints four to ten serrate and
gradually shorter, the eleventh elongate oval ; thorax slightly longer than wide,
sides rounded near the front angles, bind angles slightly divergent and with a
short carina, disc convex, a slight median depression, a slight oblique depression
on each side of the middle of the base, surface densely, roughly, submuricately
punctate ; anterior supplementary carina arcuate, directed downwards, tending
to become parallel with the anterior margin, posterior supplementary carina
long, extending three-fourths to the front; propectus with large but shallow
punctures, the rudimentary antennal groove smooth ; elytra narrower than the
thorax, gradually attenuate posteriorly, disc vaguely striate, the surface closely
and submuricately puuctate; body beneath and abdomen rather coarsely and
closely punctate ; femora piceous, tibite and tarsi paler ; last ventral segment ob-
tuse. Length .14- .16 inch ; 3.5 - 4 mm.

This insect seems to be very rare, I have seen but one specimen

collected in Maryland and kindly loaned me by Mr. Ulke.

MICRORHAGUS Esch.

Form elongate, usually narrower posteriorly ; antennse at least half as long as
the body, second joint small, third usually nearly as long as the next two, four

to ten serrate, sometimes pectinate in the male ; epistoma variable, usually very
narrow at base; propectus with an entire juxta-siitural sulcus limited externally
by an entire carina (except in liumeralis) ; lateral supplementary carina distinct,
variable between the species : posterior coxal plates variable, usually narrower
externally, in two species parallel ; tarsi slender, the first joint of the posterior
pair usually as long as the next three, the fourth joint usually broader and lobed
beneath (except in two) ; claws variably dilated at base.

Before presenting the table of species and entering upon their de-
scription it is well to explain the meaning of several terms originated
by Bonvouloir, and which I have retained for the sake of uniformity.

The anterior supplementary carina is an elevated line connected
with the apical marginal ridge near the front angles and directed
backward. This carina is short in all the species except pectinatus,
in which it extends to the middle of the side of the thorax.

The posterior supplementary carina begins at the tip of the hind
angle beneath and extends forward more or less sinuously, it is rarely
long, in two species very short {audax and imperjecius) and in another
(pectinatus) entirely wanting. This carina is really the true lateral
margin of the thorax, as in some Cardiophorini.

The j K.rta-sutural sulcus, to receive the antennae when at rest, follows
nearly the line of the prosternal suture, it is limited externally by a
well defined ridge, which is entire exce])t in humeralls and imperfectvs.

The other terms are such as are commonly used, and need no ex-
planation.

There seems to be a tendency in our species to show the gradual
obliteration of the characters which separate Adelothyreus and Mi-
crorhagus by the disappearance of the posterior portion of the outer
carina of the sulcus, the wide coxal plates and the simple tarsi.

In his tabular arrangement of the species Bonvouloir prefers to
start with characters drawn from the supplementary carinas. The
form of the coxal plates seems to me of far greater importance (it
has more than generic value in some parts of the series) in enabling
us to show more clearly the relationship between Microrhagus and
Adelothyreus.

In a paper entitled " Throscides et Eucnemides Gallo-Rhenane,"
by A. Fauvel (Rev. d'Entomologie iv, j). 338) the name Dirrhagus
Latr. is adopted in lieu of Microrhagus.

The following table will enable the species to be readily distin-
guished :

Posterior coxal plates dilated internally, narrow externally 2.

Posterior coxal plates parallel, not dilated internally ; posterior supplementary
carina very nearly entire 8.

M. peetiuatus Lee. — Piceous, moderately shining, form elongate, slightly
narrower posteriorly, stirface sparsely clothed with a very short cinereous pubes-
cence ; antennse piceous, two-thirds % , or one-half the length of body 9 > pecti-
nate from the third joint %, , or acutely serrate J ; head coarsely and rather
closely punctate, a distinct longitudinal impression between the eyes, the occiput
carinate, supra-antennal ridges distinct ; clypeus very narrow at base ; prothorax
wider than long, sides parallel, rounded in front, disc moderately convex, mod-
erately coarsely, but not densely punctured, a slight ante-scutellar carina with
a slight depression each side, hind angles finely carinate ; anterior supplementary
carina of the thorax long, reaching the middle of the thorax, posterior carina
extremely short, almo.st entirely absent; juxta-sutural sulcus slightly wider pos-
teriorly, the outer carina entire extending to the hind angles of the thorax ;
elytra as wide at base as the thorax, slightly narrowed posteriorly, disc vaguely
striate, densely and more coarsely ptinctured than the thorax; prosternum
coarsely punctured, propleurse more coarsely punctured ; metasternum and ab-
domen at sides coarsely closely punctate, at middle and apex more finely and
sparsely ; metasternal episterna slightly wider posteriorly ; legs brownish, tibi»
and tarsi paler; fourth joint of tarsi dilated and lobed beneath, claws simple,
hind coxal plates distinctly narrower externally. Length .18 -.20 inch; 4.5-
5 mm.

This species is known by the pectinate male antennae, the long an-
terior supplementary carina and the almost total obliteration of the
posterior. The latter character has been passed in silence by Bon-
vouloir, who states, by mistake, that the metasternal side pieces are
parallel.

Having seen but one specimen of this species it is impossible to say
with certainty that the pale reddish brown color of the elytra is a
constant character. It is, however, remarkable among our species
in having both the supplementary carinas very short and the median
depression of the thorax rather deep.

This sj)ecies resembles the females of pedinatus and subsiuuatus,
but may be known from any of the species with narrowed hind coxal
plates by the obliteration behind of the outer carina of the juxta-
sutural sulcus.

Occurs in New York, Massachusetts and Maryland. I am in-
debted to Mr. Fred. Blanchard for the only one I possess.

i?I. subsiuuatus Lee. — Form moderately elongate, slightly narrower be-
hind, more so in the male, piceous or nearly black, moderately shining, very
sparsely clothed with very short brown pubescence ; antennae piceous, feebly
serrate, three-fourths the length of the body '^ , or a little shorter than that 9 ;
head coarsely and moderately densely punctured, a slight depression above the
base of the clypeus ; elypeus narrow at base, not more than half as wide as the
distance between it and the eye ; prothorax wider than long % , a little less
broad 9 , narrower in front, the sides sinuate at middle % , or nearly straight 9 ,
the hind angles carinate, at tip incurved ; disc moderately convex, slightly de-
pressed at the hind angles, a distinct median impression extending from the base
to the middle, surface moderately, not densely punctured ; anterior supplemen-
tary carina at a right angle to the apical margin, extending nearly one-third
toward the base, j^osterior carina very long, reaching nearly three-fourths to
apex ; juxta-sutural sulcus deep and smooth, its external carina entire, reaching
the hind angles ; elytra obsoletely striate, moderately densely and roughly punc-
tured, the punctuation rougher and denser than on the thorax ; body beneath
rather coarsely and densely punctured ; metasternal episterna narrow, slightly
wider behind ; hind coxal plates narrower externally ; legs piceous, tarsi rufous,
fourth joint broader and distinctly lobed, claws distinctly dilated at base.
Length .14- .20 inch ; 3.5-5 mm.

In this species I have observed no s]jecial variation beyond that of
color due to various degrees of maturity. The marginal ridge of the
apex of the thorax is less develojied than usual, and the posterior sup-
plementaiy carina very long.

The female of substrlatus resembles, superficially, imperfectiis, but
the character of the posterior supplementary and the juxta-sutural
carina serve to separate them. M. substrlatus seems to have been
unknown to Bonvouloir, his description being nearly entirely quota-
tion. The measurement given is, however, incorrect, and should be
.2 inch ; 5 mm.

Occurs in Canada, Nova Scotia, Ohio, D. C. and Virginia.

WI. oblitus Bonv. — Form moderately elongate, slightly narrower posteriorly,
piceous, hind angles of thorax rufe.scent ; elytra dark reddi.sh brown, sparsely
clothed with very short yellowish pubescence ; antennae pale reddish brown,
serrate from the fourth to tenth joints, two-thirds as long as the body ; head
moderately, coarsely and densely jiunctate, slightly rugose, a slight carina on the
vertex ; clypeus at base much narrower than the space between it and the eye ;
prothorax a little wider than long, distinctly narrowed from the base to the apex,

sides slightly sinuate, basal region slightly depressed, a small ante-scutellar carina
not quite reaching the middle in front, surface rather coarsely but not densely
nor roughly punctate ; elytra indistinctly striate, the punctuation well marked
and slightly rugose. Length .18 inch ; 4.5 mm.

This species is unknown to me, and the above description is from
Bonvouloir. It apparently resembles subsinuatus more closely than
any other of onr species. It is to be regretted that Bonvouloir has
omitted special mention ( f tho supplementary carina? in nearly all
his specific descriptions as they seem important, not only in the man-
ner he uses them in his synoptic table, but for the se])aration of
closely related species.

One specimen from Illinois (Museum at Stockholm).

M. triaiigiilaris Say. — Form moderately elongate, narrower behind, pice-
ous, or nearly black, feebly shining, very sparsely clothed with short yellow-
brown pubescence ; antennae piceous, feebly serrate, extending one-half 9 , or
three-fourths the length of body % ; head rather coarsely, closely punctate, a
slight depression above the base of the clypeus,_vertex feebly carinate or not ;
clyiJeus narrower at base than the distance between it and the eye ; prothorax
with the length and width nearly equal, sides straight and parallel, arcuate at
the front angles, hind angles carinate ; disc moderately convex, a distinct ante-
scutellar carina terminating in a slight median depression ; anterior supplemen-
tary carina short, oblique, the posterior long, reaching the middle of the thorax ;
juxta-sutural sulcus smooth and deep, nearly parallel, the outer carina entire ;
surface of thorax moderately, coarsely and densely punctured ; elytra obsoletely
substriate, closely and roughly punctate ; body beneath coarsely and moderately
closely punctate ; metasternal episterna nearly concealed in front, slightly wider
behind ; hind coxal plates distinctly narrower externally ; legs brownish ; fourth
joint of tarsi broader and slightly lobed beneath, tarsal claws dilated at base.
Length .12 - .16 inch ; 3 - 4 mm.

In some specimens the thorax is impressed on each side, otherwise
there is no notable variation except in size, and somewhat in color.
Occurs from Canada to Georgia.

M. iini>re»<>!!>icolIis Bonv.— Form elongate, subcylindrical, slightly nar-
rower behind, rufo-ferruginous, feebly shining, sparsely clothed with very short
fulvous pubescence ; anteunse a little longer than half the body, joints four to ten
distinctly serrate ; head coarsely, densely and rather roughly punctured ; clypeus
broad at base and nearly twice as wide as the space between it and the eye ; pro-
thorax a little wider than long, slightly narrower in front, sides posteriorly j)ar-
allel, anteriorly arcuately narrowing, hind angles short, acute and distinctly
carinate ; anterior supplementary carina short, slightly arcuate, the posterior
very long and almost joining the apical margin; disc convex, a median im-
pressed line starting fi-om the base and reaching the middle, where it becomes
deeper and broader, surface densely, coarsely and somewhat roughly punctured ;
juxta-sutural sulcus moderately deep, but relatively narrow, the outer carina
well marked but feebler in its basal extension outwardly ; elytra distinctly striate,

the puuctuatiou less dense and finer than on the thorax ; body beneath more
shining than above, the puiictiiatiou moderate, but not dense ; metasternal epis-
terna rather broad and parallel ; posterior coxal plates much narrower externally ;
last ventral segment with a large pubescent fovea % , or simple 9 ^ the tip pro-
longed in an obtuse point % , or rounded 9 ; fourth tarsal joint dilated and lobed
beneath, the claws slightly broader at base. Length .22 - .26 in(;h ; 5.5-6.5 mm.

This is the largest species in our fauna. It is easily known by the
deep impression of the middle of the disc of the prothorax and the
very long posterior supplementary carina. The juxta-sutural sulcus
is relatively narrow, so that the space exterior between it and the
supplementary carina is at least three times the width of the sulcus.

After a careful study of a specimen in the cabinet of Dr. LeConte
in comparison with the descriptions of Bonvouloir, I feel constrained
to unite miicklm Bonv. and impremcoUifi. The former diftei's mei'ely
in the absence of the pubescent fovea in the last ventral segment,
the latter being obtuse at tip. The differences seem purely sexual,
impresi^koUh being probably the male. I am indebted to Mr. Salle
tor a typical male.

Occurs in Florida, Louisiana and Texas.

With this S])ecies Bonvouloir has associated M. Salilbergl Mann., a
rare species of Europe, which has on the penultimate ventral seg-
ment a pubescent fovea. I do not find this character mentioned by
any other European author. It would be interesting to learn if it
is merely sexual.

M. BoMVOuloiri n. sp. — Form moderately elongate, narrower behind % ,

36 GEO. H. HORN, M. D.

When fully colored this species is entirely piceous, but specimens
occur with the apical and basal margins of the thorax much paler, as
in kumeralis.

This species is closely related to Immeralk, but differs in coloration,
the thorax is also longer, the jarosternum at tip of different form and
the outer carina of the sulcus is entire. In one % specimen, how-
ever, that carina becomes very feeble jjosteriorly, but the oblique
portion is well developed.

Regarding this species there seems to be an amount of confusion
difficult to explain. From Bonvouloir's statement LeConte sent him
a specimen of this species as a type of humeralis, and Bonvouloir has
so described it. I susj^ect that LeConte sent one of those entirely pi-
ceous specimens mentioned by him (Trans. Amer. Philos. Soc. x, p.
420) in a paragraph not quoted by Bonvouloir.

While in Paris, in 1874, my friend Salle gave me from his cabinet
one of three specimens from Louisiana labeled by Bonvouloir " ar-
duus," and on asking recently for information from Salle I have been
informed that Bonvouloir has also written on the label " se place
apres humeralis," which is true of the specimen, but not of " arduus.'''
Moreover, arduus belongs to the series with the coxal })lates narrower
externally.

As Bonvouloir has certainly given wrong names to this and the
following species, I have been comi)elled to change the name to Bon-
vouloiri.

Occurs in Pennsylvania, D. C. and Louisiana.

11. Iiuiuerali^^ Say. — Form cylindrical, moderately robust, sliglitly nar-
rower behind, piceous, subopaque, elytra at base reddish, surface very sparsely
clothed with extremely short fulvous pubescence ; antennse rufo-ferruginous, as

tinctly serrate % , or not longer than wide and not serrate 9 ; head coarsely
closely and roughly punctate, smoother at middle, slightly impressed above the
base of the clypeus, supra-antennal ridges well marked ; clypeus at base wide,
equal to the distance to the eye ; thorax longer than wide, sides parallel, arcuate
near the front angles, hind angles short, carinate ; disc convex, a feeble median
impressed line, surface densely, coarsely, roughly punctate ; anterior supplemen-
tary carina short, oblique, the posterior long and very nearly reaching the apical
margin ; juxta-sutural sulcus moderately wide, slightly broader and punctate
posteriorly, the outer carina abbreviated, extending to a point opposite the front
of the coxffi ; elytra vaguely striate, the intervals often slightly convex, surface
densely and roughly punctate ; body beneath piceous or brown, densely punc-
tate ; metasternal episterna narrow in front, slightly broader behind ; hind coxal

process ]irolonged and acute ; legs ferruginous, fourth basal joint narrow and not
lobed beneath, the claws very slightly broader at base. Length .12 - .24 inch ;
3- 6 mm.

In this species the apical and basal margins of the thorax are often
pale, and the extent of red at the base of the thorax varies from a
narrow space until it covers very nearly the basal half. The under
side of the body also varies in color fr(jm ])iceous to pale brown.

This species is especially noteworthy from the abbreviation of the
outer carina of the juxta-sutural sulcus showing a tendency toward
Adelothyreus, which is further illustrated by the wide coxal plates
and the narrow fourth tarsal joint.

By some inexplicable error Bonvouloir has described this species
as new, under the name meticulosus. The descriptions by Say and
LeConte are so clear as to the color, and this in connection with the
types in LeConte's cabinet leaves no doubt as to the species they both
had in view.

Widely distributed over the United States from Canada southward,
and Bonvouloir reports it from Cordova, Mexico.

ENTOMOPHTHAI.MITS Bonv.

Antennae slender, nearly as long as the entire body, the second
and third joints very small, together shorter than the fourth.

The other characters are as in Microrhagvis. The emargination of
the eye, from which Bonvouloir derives the generic name, is variable
in extent and does not form a character separating the two genera as
traces of a similar structure are observed in M. impressicollis.

In our species the third antennal joint is smaller than the second,
while in his description Bonvouloir, by a lapsus ea/ttmrjcompares the
third joint with the fourth.

There is but one species known in (jur fauna.

divergent, carinate, disc convex, coarsely, deeply and rather clo.sely punctate ;
elytra very indistinctly striate, with coarse, deep punctures closely placed, the

large punctures, not closely placed ; metasternum less coarsely but more densely
punctured, abdominal punctures still less coarse, but more sparsely placed ; legs
ferruginous. Length .18 - .26 inch ; 4.5-5 mm.

The two specimens before me vary in color in the following man-
ner : " Head piceous, anterior margin ferruginous ; thorax piceous,
apical and basal margins rather broadly, the lateral margin narrowly
red ; elytra piceous, entire limb, base and suture paler ; body beneath
browuiish red, the metasternum piceous (typical specimen).

" Above and beneath almost entirely piceous, the base, hpex and
sides of thorax narrowly paler."

This species resembles the two European forms, but is more robust
than either, with the thorax more densely and coarsely pujictate.

GEO. H. HORN, M. D.

In the above description there will be observed two differences from
that by Bonvonloir, who says the metasternal epimera are invisible,
and in the form of the antennte. In the female the antennal joints
somewhat resemble those of Prionus, while in the male they are dis-
tinctly bipectinate, the branches l)eing as long as the joint, the front
branch arising from the distal end of the joint, while the posterior
arises from the basal end. Sarpedon is closely related to Hylochares,
but the two differ in the form of the clypeus and the structure of the
antennae.

One species is known.

pressed line extending to the occiput ; clypeus much nar-
rower at base than the distance to the eyes ; thorax quad-
rate, as long as wide, sides straight, slightly arcuate near the
front angles alone, hind angles not carinate, disc convex,

finer to the apex ; legs piceous, the tarsi ferruginous. Length .22 - .26 inch ;
6.5 mm.

The length of this species as given by Bonvonloir is 10 mm., but
the line on the plate as drawn by Migneaux is 5 mm., the former is
certainly incorrect.

Occurs in Canada, Tennessee, Nebraska, but is very rare.

The antennae differ in the proportions of their joints in our species
and will be described in their proper places.

While Nematodes is evidently more related to Schizophilus, Epi-
phanis and Hypoccelus, the resemblance in many important respects
to Dromseolus must not be lost sight of, as there are several species
of the latter genus in which the antennal grooves are rather shallow
and not as sharply limited as in the majority.

The species known in our fauna are as follows :

Color piceous or dark brown ; last ventral segment distinctly prolonged ; size

6 -9.5 mm 2.

Color ferruginous, form slender ; last ventral not prolonged, but not obtuse ; size

3.5 mm teres.

the next two, four to eleven gradually longer, each longer than wide, joints six
to eleven a little wider than the preceding joints; head coarsely, densely and
vaguely punctured, a vague triangular impression above the base of the clypeus
with a vaguely impressed line on the front ; clypeus a little narrower than the
distance to the eye ; prothorax distinctly longer than wide, widest one-third
from apex, the sides from this arcuately narrowing to the front, behind nearly
straight, slightly convergent, hind angles acute, not carinate, slightly divergent,
disc convex, slightly flattened at middle, median line impressed, extending very
nearly to the apical margin, on each side a fovea more or less impressed, surface
densely and rugosely punctate ; elytra gradually narrowed posteriorly, surface
striate, the intervals flat, densely rugosely punctate, but less coarsely than the
thorax ; jyrosternum sparsely punctate, triangle of propleurse more densely punc-
tate, the antennal depression along its middle ; metasternura coarsely punctate ;
abdomen sparsely punctate at middle, more densely at the sides and very roughly
on the last segment, the apex of which is prolonged in a point ; legs reddish
brown. Length .24 - .36 inch ; 6 - 9 mm.

This species is, as a rule, larger than the next, and differs in the
structure of the antennoe.

Occurs from Canada to Louisiana.

It is very evident that the description by Dr. LeConte has been
made ])artlv from two distinct species, and I assume that the specimen
in his cabinet bearinjj; his label must be accepted as the type of the
species. In jmiirtdtits the third antennal joint is very little longer
than the entire second and not longer than the fifth, while in the next
species the third joint is decidedly longer than l)oth the third and
fifth. In jHiriihis the antennal groove is visible only in front, whik'
in punctafiiM it is much smoother and extends the entire length of tiie
outer margin.

Occurs in Florida.

NORTH AMERICAN COLEOPTERA. 43

N. pavidus n. sp. — Cylindrical, narrower at apical third, dark brown, very
slightly shining, sparsely clothed with very short fulvous pubescence ; antennse
a little shoi-ter than half the body, paler brown, joint two a little longer than the
fourth, third a little longer than the second, but not as long as the fourth and
fifth together, fourth very little longer than wide, five to eleven gradually more
elongate and very little wider; head convex, very coarsely, roughly punctured,
a distinct depression above the base of the clypeus, which is as wide at base as
the distance to the eye ; thorax a little wider than long, sides at apical third ar-
cuately narrowing to ajiex, posteriorly parallel, hind angles acute, very little
prolonged, not carinate, disc convex, a vague median impression, surface very
coarsely and roughly punctured ; elytra striate, the intervals flat, slightly con-
vex near the base, moderately, densely, coarsely punctured, much less coarse
than on the thorax, slightly rugose near the base; presternum shining, rather
finely sparsely punctured triangle of propleurfe much more coarsely and densely
except near the margin ; the antennal depression is adjacent to the lateral margin
in front ; metasternum and abdomen moderately densely and coarsely puuctate,
the last ventral very rugose, its apex subacute, but not ])rolonged ; legs pale
lu'own. Length .26 inch ; 6..5 mm.

The above description has been made from one of the two speci-
mens used by Dr. LeConte. By the table given by Bon vou loir
(Mon. p. 647 ) this species seems most closely related to c-aneaiHa and
infu!<cati(s, from ])ot]i of wliieh it differs in form and the mode of
punctuation of the prosternum. It has also a pronounced superficial
resemblance to Microrhtgu.^ imjtre.^sicol/is. In several of the species
already described (Biarti and suspectus) the thorax has the width
equal to the length, but the ])resent is the only one known to me with
the width greater.

This species has for its type the Texas specimen referred to by
Dr. LeConte (Proc. Am. Philos. Soc. 1878, p. 404), which differs
not only by the slight antennal variation, but also in general form
and by the antennal depression visible only near the front of pro-
pleural triangle.

One specimen, my cabinet, Texas.

'X. feres n. sp. — Form slender, cylindrical, narrower behind, i)ale rufo-ferru-
ginous, feebly shining, sparsely pubescent; antennae less than half the length of
the body, second joint as long as the fourth, third longer, joints four to eleven
very gradually increasing in length, each about one-third longer than wide ;
head convex, punctuation coarser, rough and variolate, front not impressed ; cly-
l>eus at base as wide as the distance to the eye ; prothorax longer than wide, the
sides straight and parallel, arcuate slightly at the front angles, disc convex, with-
out impressions, the surface coarsely, deeply, densely and roughly punctui-ed ;
bind angles very little prolonged, not carinate ; elytra parallel, narrowed only at
apical third, striate, the intervals flat, with a single series of coarse and deep, but
irregularly placed punctures ; prosternum coarsely not closely punctured, the
mucro short, sulcate between the coxae, the propleural triangle more closely punc-

tured and without trace of aiiteiinal depression ; metasternum very coarsely and
closely punctured ; abdomen less coarsely and more sparsely punctate, the last
segment rugose, the apex not prolonged in a point. Length .14 inch ; 3.5 mm.

This species differs from all our other species in the absence of pro-
longation to the last ventral segment, a character which seems rather
of feeble value inasmuch as in penetrans I have observed a gradual
diminution of the spine and its almost total obliteration. In other
genera species have been admitted with and without the acute ti|) of
the last ventral.

From the table of species as well as by the description this s]iecies
seems very closely related to /iHpidanus, which is similar in color and
even smaller in size.

Occurs at Columbus, Texas.

In addition to the cliaracters of the table this species is distin-
*iuished from terminaUs by the distinct median impressed line of the
thorax.

Occurs in Canada, Pennsylvania and Missouri.

H. terniinalis Lee. — Form moderately elongate, slightly narrower behind,
piceous black, subopaque, sparsely clothed with cinereous yellow pubescence ;
antennte ferruginous, nearly as long as half the body, joints two and four nearly
equal, third a little longer, joints four to ten very gradually longer and broader,
the eleventh equal to ( 9 ) or longer than the two preceding ( o ) ; head convex,
densely rugosely punctate, front finely carinate, the carina extending nearly to
the occiput ; clypeus rather flat, narrower at base than the distance to the eyes ;

S€HIZOPHIL,i;S Bonv.

Form oblong, subdepressed, slightly narrower posteriorly ; antennas much
shorter than half the body, the outer joints subserrate, first joint stout, second
one-third as long, third one-half longer than the second and nearly equal to the
next two, joints four to ten very gradually longer and broader, eleventh one-half
longer than the tenth, acute at tip ; head deeply inserted, but prominent in front ;
clypeus broad at base, deeply obliquely impressed each side, truncate at middle,
deeply sinuate each side so as to appear trilobed ; prothorax narrower in front,
lateral margin entire, prosternal sutures straight well marked, slightly excavated
in front as in Elater, prosternum slightly lobed in front, sinuate each side near
the suture ; metasternal episterna parallel, the epimera invisible ; hind coxal
plates broad, triangular ; legs moderate, tarsi slender, the fourth joint obliquely
truncate, the first joint of the posterior pair as long as the next three; claws
slender, slightly broader at base.

This genus is easily known from any other in our fauna by the
form of the clypeus. But one species is known.

46 GEO. H. HORN, M. D.

S. i^ubriiriis Eand. — Color pale ferruginous, feebly shining, very incon-
spicuously pubescent; antennte passing slightly the hind angles of the thorax;

ately convex, a slight median deijression posteriorly, surface coai-sely and densely
punctate ; elytra finely striate, the intervals flat, sub-biseriately rugosely punc-
tate ; body beneath moderately densely punctate. Length .32 inch ; 8 mm.

This is rather an inconspicuous species, resembling, at first sight,
some of the paler varieties of Dolopim lateraJis. It seems to be ex-
tremely rare. I have seen but two specimens.

Occurs in Canada and New York.

EPIPHAXIS Esch.

Form rather elongate, parallel at middle, narrowed at each extremity ; antennae
slender, not serrate, the last four joints abruptly longer, varying in length in the
sexes, joints four to seven small, not hmger than wide ; clypeus arcuate in front,

coxal plates very broadly dilated internally, very narrow externally ; legs mod-
erate, tarsi slender, the fourth joint obliquely truncate, but not lobed beneath;
the first joint of the hind tarsi as long as the next three, claws broader at base.

From the description of the antennae Bonvouloir seems to have
known only the female.

There is but one species known, and which seems very widely
distributed.

E. eoriiiitns Esch. — Form elongate, parallel at middle, attenuate at either
extremity, piceous, feebly shining, sparsely clothed with brownish pubescence ;
antennfe ferruginous, a little longer than half the body % or shorter 9 ; head
coarsely and densely punctured, carinate at middle, the carina more elevated in
front ; prothorax wider than long, gradually arcuately narrowed in front, hind
angles not carinate, disc convex, with a feeble median impression posteriorly,
surface moderately, coarsely, but not densely punctured ; elytra .striate, intervals
slightly convex, densely but not rugosely punctate ; body beneath more shining

NORTH AMERICAN COLEOPTERA. 47

- This insect resembles, at iii'st glance, some of our smaller Melanoti,
and is easily known among all our Eucnemidae hy its antennal struc-
ture and the frontal crest.

Occurs from Alaska to the mountain regions of Pennsylvania, also

in New Mexico.

PHL.EGON Laporte.

Form oblong, elongate ; autennse a little shorter than half the body, first joint
moderately thick, second small, third shorter than half the tirst and nearly as
long as the next two, fonr to eight small, but at least a little longer than wide,
last three joints abruptly much longer and broader, the last joint longest; eyes
round, moderately pi-omineut ; clyi)eus inflexed, rather broad at base, apical mar-

moderately wide, jjarallel, the epimera not visible ; posterior coxal plates very
broad internally; tarsi slender, the first joint of the middle and posterior pairs
as long as the next three, the joints not lobed beneath ; claws slender, simple.

In Bonvouloir's descri])tion the fourth joint is said to be " exca-
vate-emarginate," which is not true of our species. Phlegon may be
readily known by the suddenly elongate last three joints of the an-
tennae.

Two species are known to me.

Thorax arcuately narrowed from base to apex ; hind coxal plates at the widest
portion at least one-half as wide as the length from the side to the middle.

heterocerus.

Thorax parallel behind, sides arcuate in front ; hind coxal plates less than half
the width of the coxa ITlkoi.

P. heterocerus Say. — Form oblong-elongate, a little more obtuse in front,
gradually narrower posteriorly, ferruginous brown, feebly shining, sparsely
clothed with fulvous pubescence ; autennte nearly reaching the middle of the
body % , shorter 9 • tiead coarsely and densely punctured, front broadly im-
pressed, a feeble impressed line on the vertex ; thorax one-third wider than long,
arcuately narrower from base to apex, hind angles not carinate ; disc convex, a
vague median impressed line posteriorly, surface with moderate punctuation,
rather closely placed ; elytra narrower posteriorly, surface distinctly, but finely
striate, the intervals slightly convex, densely punctate, the punctures finer than
on the thorax but rougher ; body beneath more shining than above, punctuation,
dense and rather fine. Length .40 - .44 inch ; 10-11 mm.

concealed behind the first, half as long as the third, third as long as the next
two, which are nearly equal, six, seven and eight equal, quadrate, nine and ten
equal, together as long as the preceding six, eleventh joint long, equal to the
preceding two, obliquely impressed at its anterior two-thirds.

Female. — Joints one to eight as in the male, joints nine to eleven together a
little longer than three to eight together, joints nine and ten broader and equal
the tenth more slender and a little longer.

48 GEO. H. HORN, M. D.

The general aspect of this insect is that of some of our brown
Ehiters. As will be seen above the sexes are quite different in the
form of the antennae ; the male seems rare.

Occurs in jNIaryland, Pennsylvania and Indiana (Say).

P. Ullcei n. sp. — Form oblong, parallel, equally obtuse before and behind,
dark brown, moderately shining, sparsely clothed with short fulvous pubescence ;
antennae shorter than half the body 9 ; head coarsely and densely punctured,

wider than long, sides behind straight and parallel, apical third arcuate, hind
angles not carinate ; disc convex, a feeble median impressed line, nearly obliter-
ated at middle, surface moderately punctured, densely toward the sides and base,
more sparsely at middle ; elytra parallel, obtuse at apex, narrowing at apical
fourth, distinctly finely striate, the intervals flat, densely punctate, the punctures
finer than on the thorax, but not rugose; body beneath densely and rather finely
punctate. Length .38 - .40 inch ; 9.5-1(1 mm.

Male. — Antennse with first joint as long as the next three, second small, partly
concealed behind the first, half as long as the third, third equal to the next two,
which are equal .sixth, seventh and eighth a little shorter, equal, ninth equal to
sixth, seventh and eighth together, tenth shorter than the ninth, the eleventh
longer.

Female. — Third joint of antennse nearly as long as the next two, fourth and
fifth equal, sixth, seventh and eighth subequal, longer than wide, each a little
shorter than the fifth joint, ninth broader than the eighth and as long as the
three preceding, tenth a little shorter, eleventh longer and more slender than the
ninth.

Broader and more obtuse than heterocerus, with finer punctuation
and pubescence, and with narrower hind coxal plates.
.Occurs in Ohio ; given me by Mr. Ulke.

CRYPTOSTOMA Latr.

Form oblong, parallel ; antennse varying in the sexes ; head rather deeply in-
sei'ted, eyes transverse ; clypeus narrowed at base, narrower than the distance to
the eyes, apical margin broadly arcuate, mandibles presenting a narrow face ex-
ternally ; prothorax a little wider than long, lateral margin distinct in its entire
length ; scutellum oval ; elytra striate ; prosternal sutures straight, well defined,
very slightly divergent, propleural region triangular, the apex truncate, not sul-
cate for the antennse ; metasternal episterna moderately wide, parallel, the
epimera not visible ; hind coxal plates gradually but widely dilated internally ;
legs moderate ; tansi slender, the first joint as long as the next three, the fourth

The only genera in our fauna to which this is allied are Anelastes
and Phlegon, from either of which it may be so easily known as not
to require special comparison here.

One species is known to me, and the specimen is a female, and the
following description of the antenna) applies to that sex alone :

NORTH AMERICAN COLEOPTERA. 49

C Dohriii Horn. — Oltlons, moderately elongate, parallel, equally obtuse at
either extremity, color bright blood red, elytra black, a humeral spot and the
apical fifth red, beneath red, sides of body and abdomen black, surface finely

basal joint red, not passing the hind angles of the thorax, first .joint stout, equal-
ling the next two, second small, partly concealed, third nearly as long as the next
two, four to eight equal in length, very gradually shorter, nine to eleven a little
wider, the last joint abruptly truncate ; head moderately convex, coarsely and
closely punctate, a vague triangular flattening above the base of the clypeus;
thorax a little wider than long, sides parallel at basal third, then arcuately nar-
rowing to the front, hind angles very little prolonged, not carinate, disc moder-
ately convex, a transverse, slightly oblique depres.sion on each side near the
middle, another on each side beginning at the base opposite the middle of each
elytron extending in an arcuate manner forward and outward, surface densely
and moderately coarsely punctate ; elytra striate, the .strise entire except the
second and third, distinctly punctate intervals flat, slightly convex near the base,
densely and slightly roughly punctate ; body beneath nearly equally i)unctate
throughout, the punctures not dense ; legs red. Length .60 inch ; 15 mm.

Ill the other species of the genus the anteiiiic\3 are otherwise con-
structed in the male, the third joint liaving a lobe or process near
the base.

This species is the only brightly colored form in our fauna. The
specimen in my cabinet was given me by Dr, C. A. Dolirn, who pos-
sesses another, which was said to have been collected at San Diego,
CaL, but as I have found at least one other species in the same lot
from Yucatan, this species may be from that region.

A]VEL.ASTE!li Kby.

Form oblong, convex, slightly narrower behind ; autenuse extending very little
beyond the hind angles of the thorax, joints four to teu short, nearly equal, sub-
moniliform, the last joint a little longer, abruptly acuminate at tip ; head deeply
inserted, eyes entire, not very convex , clypeus short, arcuate in front, much
narrower at base than the distance to the eyes; prothorax broader than long,
slightly narrower in front, sides arcuate, lateral margin indistinct; .scutellum
triangular, obtuse at tip ; propectus without antennal grooves, prosternal sutures
straight behind, arcuate near the front ; prosternum rather broad between the
coxaj, obtuse at tip ; metasternal epi-sterna broad, slightly narrower in front ;
hind coxal plates extremely narrow externally, rectangularly dilated at inner
third ; legs moderate, tibiae slightly broader at tip ; tarsi slender, not lobed be-
neath, first joint of the posterior pair equal to the next two, claws slender.

One species is known in our fauna.

A. Druryi Kirby. — Castaneous or rufo-ferruginous, opaque or very feebly
shining, sparsely clothed with almost imperceptible brown pubescence; head
finely but not densely granulate, front with a finely imjiressed line ; thorax
broader than long, but variable in its extent, slightly narrower in front, sides
arcuate, but variably sinuate in front of the hind angles, which are slightly di-

vergent, not carinate ; disc convex, a median impressed line more distinct poste-
riorly, surface granulate, but not densely ; elytra deeply jiunctato-striate, inter-
vals convex, finely punctate and granular near the base ; body beneath densely,
very finely punctate, the sides of the propectus granular. Length .34 - .50 inch ;
8.5-12.5 mm.

Male. — Posterior '.tibia? fimbriate with rather long yellowish hairs at apical
third of inner edge ; first joint of hind tarsi fimbriate beneath.

Female. — Posterior tibise^aud tarsi not fimbriate.

There is considerable variation in form, size and color in this in-
sect, and specimens often occur with four depressions on the disc of
thorax. It is absolutely impossible to distinguish two species in our
fauna.

Bonvouloir mentions the occurrence of a specimen in Astrabad
which he cannot distinguish from ours, and the differences given to
separate barbarus seem more forced than real.

Occurs from Vancouver eastward to Canada and in the Atlantic
region as far south as Georgia.

CEROPHYTIN.E.

Head flat above, front gibbous, slightly prominent ; clypeus inflexed, mouth
inferior , antennae, iiectinate in the males, strongly serrate in the female ; elytra
wider at base than the thorax ; anterior coxal cavities narrowly open behind, the
posterior coxae depressed without plates, the trochanters rather long, claws pecti-
nate at base.

Bonvouloir correctly remarks that the curious characters of the
genus Cerophytum have caused some discussion on the position it
should occupy. He admits it among the Eucnemides, but as a dis-
tinct group. Lacordaire (Genera iv, p. 244) makes it the type of
a distinct family, which he places between the Cebrionides and Rhipi-
cerides. In this I think Lacordaire more nearly correct than Bon-
vouloir, at the same time a relationship seems to exist with the Das-
cyllidse, especially the ti'ibe Artematopini {Macropogo^iini Lee.)

One genus is known.

CEROPHYTlIfl Latr.

Eyes large, round, prominent ; labrum not visible ; mandibles slender, arcuate,
prominent, acute at tip; last joint of maxillary jialpi securiform ; thorax trans-
verse, the hind angles slightly prominent, the lateral margin very obtuse ; scutel-
lum triangular ; prosternum lobed in front, the sutures simple, slightly arcuate,
but not divergent in front, the apical process imperfectly received in the excava-
tion of the mesosternum ; metasternal episterna gradually wider behind, epimera
not visible ; posterior coxfe on the same plane as the ventral segments, the outer
extremity in contact with the elytra ; legs moderate, the anterior femora grooved

NORTH AMERICAN COLEOPTERA. 51

on the lower edge for the tihiaj, the trochanters of the anterior legs small, of the
middle longer, of the posterior nearly as long as the femur ; tibise slender, the
spurs distinct ; tarsi not elongate, rather flat, the first joint of the posterior pair
as long as the next three, the fourth excavate-emarginate, claws ]K;ctinate in
their basal half; body alate.

The two species in our fauna may be distinguished in the following
manner :

Antennte pectinate 2

Autennffi serrate 3

2. — The pectination beginning on the third joint ]>uI»$atOi* %

The pectination beginning on the fourth joint coiivoxicolle %

3. — Third joint of antennse a little longer than the fourth i>ul!>»ator 9

Third joint as long as the next two coiivexicolle f

In addition it will be observed that the claws are thicker at base
in j)idmt(rr, and the pectinations numerous, while in convexlcolle the
claws are slender and pectinations not more than two or three.

C pulsator Hald. — Oblong, moderately convex, black, feebly shining,
sparsely clothed with short cinereous pubescence; antennse piceous, a little
shorter than half the body ; head densely punctate, rugose ; clypeus narrower at
))ase, obtusely elevated along its middle ; thorax very much broader than long,
sides strongly arcuate in front, slightly convergent posteriorly, the hind angles
slightly everted, disc convex, coarsely and densely punctured ; elytra wider at
base than the thorax, the humeri distinct but obtuse, sides parallel, arcuately
narrowing at apical third, disc moderately convex, deeply striate, the striae
coarsely and closely punctate, intervals flat, densely punctate and slightly rugose ;
body beneath densely and rather finely punctate, finely pubescent, metasternum
more coarsely punctate ; legs piceous, tarsi ferruginous. Length .28 -.34 inch;
7-8.5 mm.

Male. — First joint of antennse stout, second small, triangular, joints three to
ten subequal, each with a clavate branch arising from the ba.se in front, that from
the third a little shorter than the others, eleventh joint clavate, a little longer
than the jireceding two.

Female. — First joint stout, .second small, third longer than the fourth, joints
four to ten dentate within, the eleventh joint a little longer than the tenth.

Occurs from Pennsylvania to Illinois and North Carolina ; very
rare.

C OOiivexicolle Lee. — Oblong, moderately elongate, black, subopaque, very
sparsely cinereous pubescent ; antennse shorter than half the body, piceous ; head
coarsely, densely punctate ; clypeus narrow at base, obtusely carinate along the
middle ; thorax much broader than long, sides in front arcuate, posteriorly
slightly convergent, the hind angles slightly i^romiuent, disc convex, coarsely,
densely and subrugosely punctured ; elytra wider at base than the thorax, the
humeri distinct but rounded, sides parallel, arcuately narrowing at apical third,
disc moderately convex, strise not dee]), coarsely and closely punctate, the inter-
vals flat, finely but not densely punctured, slightly wrinkled transversely ; body
beneath more shining, the punctuation rather fine but not dense, coarser on the
prosternum ; legs brownish. Length .26 -.28 inch; 6.5-7 mm.

52 GEO. H. HORN, M. D.

3Ifile. — First joint of antennae stout, second small, third longer than the fol-
lowiuo;, triangular, the apical angle very slightly prolonged, joints four to ten
with a branch of clavate form arising from the base of each, eleventh joint mod-
erately elongate, clavate.

Female. — First joint stout, second small, third elongate, triangular, nearly as
long as the next two, joints four to ten broader than long, serrate within, joint
eleven elongate oval, ^obtuse at tip and not as long as the preceding two.

This species closely resembles the preceding, but is more elongate,
the elytra! striae less deep, and the intervals less densely punctured.
The structure of the antennj^ will readily distinguish the two species.

Of this species I have seen but two specimens, the male collected
by Dr. Schaum near Sacramento, now in the cabinet of Dr. LeConte,
a female collected by myself at Fort Tejon, California.

PEROTHOPIN.E.

Head moderately convex, front slightly narrowed by the insertion of the an-
tennse under distinct supra-antennal ridges; labrum short, transverse, connate
with the front, the suture almost entirely obliterated, the clypeus very short, as
in Elateridae ; mandibles acute, arcuate, fimbriate on the outer side; prosteruum
slightly lobed in fnmt, the mucro short ; hind coxse. laminate, claws pectinate.

The difficulties which authors have realized in dealing with Pero-
thops have already been alluded to. I can only repeat what I have
elsewhere pulilished that the genera Eucnemis, Elater, Cebrio, Pero-
thops and Cerophytum do not represent such different types of struc-
ture as to require them to be made separate families. They are
indeed very closely related, and the discussion which has prevailed is
indicative of that fact. That they differ sufficiently to be separated
in groups of less than a family value is evident, but they should
be associated as modifications of one type, and for that aggregation
I prefer the name Elateridae.

In Perothops the structure of the front of the head is 2)ractically
the same as in Cebrio. In both the clypeus is quite short as in
Elateridae, and to its front margin is fixed the labrum, short and
transverse, immovable in both. The suture is very distinct in Cebrio,
but almost obliterated in Perothops, W'here it is only visible in imma-
ture specimens, or those softened with solution of caustic potassa.

In the Eucnemides, however, the clypeus is of different form and
the suture between it and the front is a short distance below the nar-
rowest part between the antennae, while the labrum is at most very
small and retracted, practically invisible Avith very rare exception.

NORTH AMERICAN COLEOPTERA. 58

In both Perothops and Ceropliytuni the claws are pectinate, while
in all the genera of Eucneniides they are either simple or at most
broadly toothed at base.

PEROTHOPS Eiichs.

Head moderately convex, clypeus short not inflexed, the labriim continuous
and connate with it ; mandibles prominent, arcuate, acute at tip, ciliate exter-
nally ; eyes oval, moderately prominent, entire ; maxillary palpi moderately long,
the last joint securiform; antennse slightly narrowing the front, arising under
rather prominent ridges, the first joint elongate conical, second one-third as long,
obconical, third two-thirds as long, fourth longer than second, joints four to
eleven differing in the two species, the eleventh truncate at tip ; thorax broader
than long, the lateral margin indistinct, hind angles not prolonged ; scutellum
oval ; elytra striate ; prosternum slightly lobed in front, the mucro short, the
sutures straight, slightly divergent; mesosternal side pieces diagonally divided,
equal ; metasternal episternum moderate, parallel : hind coxfe with plates
broader internally ; legs moderate, tibia? slightly broader at tip, the spurs small ;
tarsi shorter than the tibiae, slightly compressed, the joints obliquely truncate
at tip, joints one to four gradually shorter, the first, however, stouter, especially
on the posterior pair, claws pectinate their entire length ; body winged.

Two species are known to me in our fauna.

Lateral marginal line of thorax visible only near the hind angles; antennal
ridges transverse, not meeting on the front ; hind coxal plates more abruptly
dilated internally and wider; joints four to nine of antennje gradually longer,
ten to eleven equal and a little shorter luticicla.

Lateral marginal line of thorax visible from the hind angles half way to the
front ; antennal ridges oblique, meeting on the front ; hind coxal plates very
gradually broader internally ; joints four to eleven of antennse equal in length.

Wittieki.

In both species the antennae are slightly flattened externally.

While there are but two species above, a third is in the " Cata-
logus" credited to California, and which is figured by Lacordaire
( Atl. ])1. 41, fig. 8), but not described, under the name cervina. This
does not bear the remotest resemblance to either of our species, and
I think there must be some error on the part of Lacordaire, as the
species mentioned in the Dejean catalogue (third ed. p. 99) is prob-
ably our common mi(eida sent to him by Ma_i. LeConte. That cervina
Dej. is mucida Gyll. was also the opinion of Erichson (Germ. Zeitschr.
iii, p. 117).

P. iunei<la Gyll. — Form oblong, parallel, piceous % or ferruginous brown
9 , feebly shining, sparsely clothed with cinereous pubescence ; head moderately
convex, the punctuation intermixed, the coarse sparse, the fine dense; antennae
as long as half the body % , a little shorter 9 ; thorax wider than long, narrower
in front, the sides feebly arcuate % , or more strongly J . with a slight sinuation

in front of the hind angles which are subacute, the lateral margin extremely
feeble and slightly inferior ; disc convex, a feeble depression of the median line
posteriorly, the surface with an inconspicuous intermixed punctuation, somewhat
rugose at the sides ; elytra striate, striaj iiunctate, intervals flat and equal 'J, , or
alternately slightly narrower and more convex 9 » the surface inconspicuously
finely punctate, with somewhat coarser punctures intermixed ; body beneath very
finely and moderately densely punctate, with slightly larger punctures inter-
mixed, which are larger on the sides of prothorax ; legs similar in color to the
surface. Length .42 - .80 inch ; 10.5-20 mm.

In addition to the fine pubescence there are s])arsely placed, serai-
erect, short hairs. The males are known by their usually darker
color, more slender form, antenna? longer, and the elytral intervals
equal.

Occurs from Pennsylvania to Florida.

P. Wittifisi Lee. — Form oblong, parallel, rather robust, piceous or brownish,
clothed with fine yellowish cinereous sericeous pubescence; antennae nearly as
long as half the body % , a little shorter 9 ; head coarsely, sparsely punctate,
with fine punctures between, front vaguely longitudinally impressed, supra-an-
tennal ridges nearly transverse, united across the front ; thorax much wider than
long, narrower in front, sides strongly arcuate, slightly sinuate in front of the
hind angles which are subacute, lateral margin distinct from the hind angles
two-thirds to apex ; disc very convex, median line slightly impressed posteriorly,
surface not densely punctate, the intermediate finer punctuation very indistinct ;
elytra very little wider at base than the thorax, parallel, narrower at apical third,
striate, strife indistinctly punctate, the intervals slightly convex equal, sparsely
punctate, the finer intermediate punctuation almost obsolete ; body beneath
densely finely punctured with coarser punctures sparsely placed, which are
coarser on the prosternum, the pubescence fine, silken and moderately dense ;
legs similar in color to the body. Length .62 - .80 inch ; 15.5 - 20 mm.

This species greatly resembles muclda; it has, however, a more
robust facies, the pubescence is closer and more silken. The most
obvious structural differences are those given in the table.

Occurs in the middle reirion of California.

NORTH AMERICAN HYMENOPTERA. 59

Synopsis of* the ^^ortlt Aiiiericaii Siib-raiuilies and
Genera of CYXIPID^E.

BY WILLIAM H. ASHMEAD.

Family— CYNIPIDJE.

Head generally (<niall, transverse ; labruni very minute ; mandi-
bles short, robust, toothed ; maxillary palpi -Vjointed, labial palpi 2
to 4-)ointed ; antennae slender, filiform, or sub-filiform, inserted on
the middle of face, 12 to 16-jointed ; thorax generally thick, oval;
scutellum large, variable ; wings with few nervures, anterior pair with
seldom more than three or four cells, posterior pair with but a single
thickened vein, occasionally apterous ; abdomen petiolate or sub-ses-
sile, oval, elongate Qval or compressed, and usually with the second
or third segment the largest ; ovipositor spiral, hidden within two
sheaths or plates ; legs ordinary.

Classificaiion of ihe North Americroi Species.

Authors are by no means agreed in their arrangement of the com-
plexity of forms recognized as Cynips, and in the present essay will be
found a new classification, in accordance with what seems to me the
most natural method and for which I am alone responsible.

The forms peculiar to our fauna seem naturally to divide into two
sections, distinguishable from each other by venation and ventral
charactei's as follows :

Section I, Gymxogastri. — Venter visible, or visible for moi'e than
half its length ; radial area long and narrow.

Section II, C-ryptogastri. — Venter not visible, or with the tip
alone occasionally exposed ; radial area an equilateral triangle.

The first section includes the true gall makers or Psenides, the guest
flies or Inqul/ines, and the peculiar genus Ihalia.

Their habits as far as known are phytophagous, although the
Ibalite are supposed to be parasitic on wood-boring larvae, and by
some authors are placed with the Figltides. Their characters, how-
ever, place them naturally with the phytophagic Cynipidse.

In the second section are included all the parasitic Cynips or Figi-
f!flp.<< : all are strictly entomophagous.

60 W. H. ASHMEAD.

The North American Cymphlse may be divided into five sub-fiimi-
lies of nearly equal value, distinguished by characters given in the
following table :

Synoptic Table of the Sub-families.

Section I.— GYMNOGASTRI Ashmead.

* Radial area long and narrow.

A. — Radial area closed ; abdomen cultTiform, segments about equal ; venter

visible Sub-family I, IbaliinjE.

AA. — Radial area seldom closed ; second abdominal segment occupying half, or but
little more than half the whole surface of abdomen ; venter visible.

Sub-family II, Cynipin^.
AAA. — Radial area seldom open ; second abdominal segment occupying the whole
or nearly the whole surface ; venter not visible its whole length.

Sub-family III, Inquilin^.

Section II.— CRYPTOGASTRI Ashmead.

** Radial area an equilateral triangle.

B. — Abdomen short, globose, or semi-globose ; second abdominal segment longer
than the others ; scutellum round, convex.

Sub-family IV, Allotriin^.

BB. — Abdomen elongate ovate, compressed, with apex more or less pointed ;
third alidominal segment the largest ; scutellum quadrate, cupuliform
or spined Sub-family V, FiGlTlN^.

Section I.— GYMNOGASTRI Ashmead.

Sub-family I. — Ibaliin.e.

This group contains one genus, easily recognized bv the following-
characters :

Abdomen cultriform with all the segments about equal, fifth segment in 9
being much larger than in % ; wings with the veins more strongly devel-
oped than in any other of the Cynipidous groups ; radial area very long,
narrow and closed ; antennae filiform, 9 13, % 15-jointed.

(1) Ibalia Latreille.

Sub-family II — CH'nipin^t:.

To this grou]) belong the true gall makers ; they produce galls or
abnormal deformations and excrescences on various trees and plants ;
the oak-rose and bramble being particularly subject to their attacks.

It is by far the largest and best known of the different groups,
nearly one hundred species having already been described in the
North American fauna, which rei)resent thirteen genera.

The genera may be separated with the aid of the following table :

My genus Dri/orhizo.renn,'^ and Befo)iocn.ema INIayr, are identical,
and were described about the same time. While there can be no (ques-
tion raised as to my having forwarded my descri|)tion for publication
first, yet from correspondence with Dr. Mayr I find he has jjriority
in pul)lication, and I have given his name the preference.

Sub-tamily III. — Inc^uilin^.

All the species in this group are termed guest fliies ; they are gal-
livorous and live in the galls made by species of the former sub-
family, from which they are hardly distinguishable.

The much larger second abdominal segment and tlie almost always
closed radial area easily distinguish them.

The species in our fauna represent but four genera separated as

The genera may be separated by the following table:

A monograph of f lie speoies of C'HRTSOBOTHRIS
inhabiting the United State*^.

BY GEORGE H. HORN, M. D.

Since the publication of the " Revision of the Buprestidae of the
United States," by Dr. LeConte (Trans. Amer. Philos. Soc. xi, 1859),
the species of Chrysobothri^ have remained practically undisturbed.
There have been in the meantime but six species described, of which
two are valid. The material has been allowed to accumulate in our
cabinets until enough has been obtained to supply defects in the
original series and to render it probable that veiy few more new spe-
cies will be discovered. Nor has it appeared that science has seri-
ously suffered by retaining many of the species more than twenty
years without names, and it is highly probable that much unnecessary
synonymy has been avoided by the aggregation of series, which at
the same time indicate the great variability of many of our species
and the real characters separating them. The publication of descrip-
tions of isolated species in advance of any monographic work, or
preparation for it, must necessarily be done at the risk of insuffi-
ciency as important characters are frequently developed by serious
study which are overlooked in the haste of descriptive work. Chryso-
bothris is no exception, and the books are foil of descriptions, some
of which having no value in themselves are useful merely in fixmg
specific names in our literature until comparison places them in the
grand crowd of synonyms. Our species have quite their shai'e of
synonymy, jn'incipally due to Laporte and Gory ; for, of the twenty-
two species mentioned by them together or by Gory in the supple-
ment, l>ut five remain valid and one (errans) does not belong to our
fauna, and it may be added that the figures in their work leave much
to be desired and the descriptions are, for the most part, very insuffi-
cient.

Anterior to the " Revision" above cited the species described by
Laporte and Gory were made the subject of a special synonymical
study by Dr. LeConte, and the results published in Proc. Acad.
1857, pp. 6-10, with approximately correct conclusions which were
confirmed or corrected by studies of the types then in the possession
of Count Mniszech, in Paris (Proc. Acad. 1873, pp. 330-333).

TRANS. AMER. ENT. SOC. (9) MARCH, 1886.

()6 GEO. H. HORN, M. D.

The types of the species described by Melsheimer were obtained
by the Museum of Comparative^ Zo()h)gy at Cambridge, and for a
long time were loaned to Dr. LeConte, many of them still remaining
in his cabinet, now part of that Museum.

The species described by other authors anterior to the " Revision"
are fcAV in number, and fortunately definitely known. Typical s])eci-
mens of all the species described by LeConte are, with one exception,
in his cabinet.

The few inunediately preceding remarks indicate the authority for
the names which will be used for the sj^ecies in the f )llowing ])ages,
while the work itself is based on an aggregation of material which
it would be impossible at the ])resent time to equal.

During his life-time LeConte's cabinet and my own were used in
conunon with the result of making them similar in the names of the
species and by interchange of specimens as nearly equal as possible
in numbers. I have already remarked that close monographic study
usually develops previously unnoticed characters, and, as will be ob-
served in the following pages, the exact definition of several of the
species became somewhat uncertain. A renewed study of many of
LeConte's types became necessary, and fi)r this possibility I must re-
turn my thanks to the jMuseum of Comparative Zoology for the
freedom with which they have permitted me to use not only these,
but also all other material in their possession. The series in the
National ^Museum at Washington has been kindly loaned me.

Among the personal friends who have assisted me by the loan of
their entire collections Mr. Ulke, of Washhigton, requires sj)ecial
mention, his series being very full and his specimens the perfection
of neatness.

To Messrs. Edwards, Angell, Merkel and Reinecke, of New York,
Fuller, of New Jersey, Pergande and Lugger, of Washington, Hen-
shaw, and Blanchard of Massachusetts, Wilt and Wenzel, of this
city, I am also indebted for the loan of smaller series which have
been useful in their aggregation by indicating points of distribution
not otherwise known. My own cabinet contains all the species with
one exception.

Regarding the number of specimens examined — of thirty-three
species, I have seen ten and over, in many cases hundreds, seven
with five or six, five with three or four, one with two, while four only

NORTH AMERICAN COLEOPTERA. 67

are uniques. In the fifty species enumerated both sexes are described
of forty-two, seven are known only by females, one by the male.

Having an unequaled oppoilunity in both the quality and quan-
tity of material, it remains to be seen whether the results of my study,
as given in the following pages, will make a really difficult subject
comprehensible to others.

The genus as recognized in the following pages is in full accord
with those who unite Chrysobothris and Colobogaster, the reasons for
which have been aptly given by James Thomson, in " Typi Bupres-
tidarum," App. 1, p. 40, and need not be repeated here further than
to say that the size of the cavities for the articulation of the antennae
is very variable in our species. The first joint of the hind tarsi is
always as long as the next three, frequently much longer.

The general form of the species is variable, but the variation is
not as great as in some genera, such as Psiloptera, which are truly
lX)lymorijhic: For a better idea than can be given by description
the reader is referred to the annexed sketches.

In the various synoptic tables some of the characters used are
common to both sexes, others are purely sexual. In the first cate-
gory are those found in the surface of the thorax, the anterior mar-
gin of prosternum, the last ventral segment, and finally the clypeus.

The disc of the thorax may be regular and even, more or less
equally punctured and without either grooves or irregular elevations,
this is illustrated in the first six species on Plate ii and others on
Plates vi-vii. The irregular disc, that is with grooves or irregular
callosities and with usually uneven punctuation, is by far the most
abundant form, and, in our fauna, more characteristic of the genus,
see Plates iii and iv.

The anterior margin of the prosternum may be lobed or truncate,
neither character being ])eculiar to any of the groups into which I
have divided our species. The truncate prosternum occurs in den-
tipe^, trinervia and the related species as well as elsewhere, the form
is illustrated by diagram fig. 98. In those species in which the pros-
ternum is lobed in front, the lobe varies greatly in form and size —
from a simple arcuation of the middle of the front margin (fig. 99)
to an abrupt, well developed projection (fig. 22).

68 GEO. H. HORN, M. D.

The last ventral segment by the character of its lateral margins
enables us to divide the genus into two primary series. In the first
the margins are distinctly serrulate, sometimes strongly so, occasion-
ally simply crenulate, many illustrations will be found on Plates ii
to V. In the second series the lateral margins are not serrulate, as
shown on Plates vi-vii, although in two species, cerea and Ubonoti
(figs. 175-176 and 195-196), the margin is interrupted beyond the
middle.

The firm of the clypeus appears to have escaped observation, or
at least description by nearly every author, and no one seems to have
attached the importance to it which it deserves. The usual emar-
gination of the clypeus is triangular or oval, the broader the emar-
gination the more shallow it becomes. There are, however, several
curious forms as shown in figures 12, 81, 36, 46, which are, with the
exception of 36, restricted to a single species in each case. Other
modifications probably occur in exotic forms and will doubtless be
more accurately observed in the future.

Modifications of structure dependant on sex are very numerous,
and occur in many parts of the body and its members. Descriptions
are given as fully as necessary under each species and many of them
illustrated on the plates, so that but little more than a few general
remarks will be here given.

Form of body. — There is but little diflTerence in the sexes except
that the male is often more slender and the female more convex.

Head. — This varies in form, color, sculpture and pubescence.

Fortn. — The front of the male is usually nnich flatter, the female
more convex.

Color. — Frequently the male head is green, while that of the
female is aeneous or cupreous.

Sculpture. — In the majority of species the front is much more
densely and finely punctured and the callosities indistinct or want-
ing in the male, while in the female the punctures are coarser and
sparser and the callosities prominent. It is rare that the callosities
are more prominent in the male, while in a small number of species
the front is similarly (that is, coarsely and sparsely) punctured in
both sexes.

Pubescence. — In those species with a very flat front that portion
is quite densely pubescent in the male and scarcely so in the female.

NORTH AMERICAN COLEOPTERA. ^ 69

Antenn.e. — These difter in form and color.

Form. — The only instance of variation of form occurs in group
viii, in which the only known male has the lower edge doubly serrate
(fig. 238). In the females of this group the lower edge of the an-
tennae is broader than in the species of the preceding series.

Color. — The most common difference is that the male antennae
are brighter in color, green or cupreous, while in the female they are
bronze or piceous. In acutipennis joints four to eleven of the male
antennae are more or less testaceous, in the $ bronze.

Prosternum. — It is quite common to find the same differences in
the prosternum as have been observed in the front, that is, more
densely punctured and finely pubescent % , or more coarsely and
sparsely punctured and less pubescent 9 . It is, however, not rarely
that both sexes are similar and have coarse, sj^arse punctuation, or
the prosternum may be very nearly smooth.

Legs. — The femora show no perceptible differences in the two
sexes, except that in the males they are slightly stouter. The tooth
is similar.

Tihixe. — The differences between the two sexes is usually very
well marked. In the female the tibia is at most feebly arcuate
without apical dilatation or tooth or serration on the inner edge. In
two species, aziirea (221) and atrifaseiata (242), the tibiae are so nearly
alike in the sexes that the difierences might readily escape observa-
tion, and in libonoti (197) they do not differ at all. In the males
the anterior tibiae are always more or less arcuate, and in one
species impressa (202) angularly bent. A comparatively small num-
ber of species have the anterior tibiae serrulate on the inner margin,
and in these it will be observed that the aj^ical dilatation is either
feeble or null. Those with the tooth at a greater or less distance
below the middle are even less numerous. The apical dilatation is
of very variable form and size, as will be seen on the accompanying
sketches. The middle tibiae show much less variation, but in floricola
(50) they are distinctly sinuate, in a few other species the tip is
slightly thickened, while in femorata and Merkelii they are nearly as
serrulate as the anterior tibiae. In a large number the middle tibia
S is arcuate, but much less than the anterior, while in the $ it is
usually straight. In but one species, scabripennis, the posterior tibia
% is arcuate.

70 GEO. H. HORN, M. 1).

Last Ventral Segment. — In all our species the last ventral
segment is emarginate in the male, but variable in extent among the
species, from the deep quadrangular ncjtch of rjemmata (180) or
acufipeiuiis (190) to the feeble arcuate truncation of chrijmela (229),
seitH/it{2o4) or atrifcisciata (240). It is not often that the disc is
carinate in the male, and then the carina is short, and never entire,
as in the female. The disc is more commonly broadly sulcate at
middle as in Merkelii (185) or aentipe)tiiis (190). The last ventral
of the female is rarely as deeply emarginate as in its male, analis
(210), usually much less so and quite often truncate as in acvtipennis
(191) or geimnata (181), sometimes more or less sinuate as in chri/soela
(230), scihda (235) or utrifasciata (241). The tridentate form of
apex is rare, libonotl (196). Many modifications of the emarginate
type will be observed in the sketches. The disc is often strongly
carinate in the female, the carina extending from the base to the
apex as in octocola (9), gemmata (181) or Merkelii (186). The last
dorsal segment often differs in the sexes, principally in sculpture, the
punctuation in the female being coarser and deeper than in the male.
It will, however, be observed that in feiuomta the last dorsal of female
is carinate at middle, a deep fovea on each side.

From the preceding remarks, which have been condensed as much
as possible, it will be seen that modifications of a purely sexual im-
port occur in many portions of the body, which can be utilized in
more accurately defining species. The form, color and sculpture of
species are often so variable that two specimens of different species
will more closely resemble each other superficially than other indi-
viduals of the species to which they belong. This is especially ob-
servable in the trinervia series, where recourse to sexual characters is
the only means of separating the closely allied members.

The species of Chrysobothris are so numerous in our fauna that
they may be best understood by dividing them into groups. The
primary division adopted is practically that i)roposed by Dr. LeConte
in his Revision, with such modifications as have been rendered neces-
sary by the increased material. It nnist not be supposed that these
" groups" are such natural divisions that they have equal value, they
are merely adopted for convenience, and those who study the species
will find many points of resemblance between members of widely
separated grou])s, e. g. femoratu and ^ie.vsi g imta.

NORTH AMERICAN COLEOPTERA. 71

The following is the scheme :

Lateral margiu of last ventral segment serrulate (3-171).

Disc of thorax even, without fovese or callosities (1-25) Group I.

Disc of thorax irregular, median line more or less sulcate, often with callosi-
ties (30-164).
Anterior tibife % arcuate and serrulate within ; clypeus acutely notched at

middle, semi-circularly arcuate each side (30-34) Group II.

Anterior tibise % arcuate and with a tooth near the tip (35-65).... Group III.
Anterior tibise % more or less arcuate, dilated at tip (66-172).

Form depressed (66-145) Group IV.

Form subcylindrical, slightly pubescent (150-169) ' Group V.

Lateral margin of last ventral segment not serrulate, rarely interrupted (175 -246).

Elytra acuminate at tip (173-193) Group VI.

Elytra obtuse and serrulate at tip (198-244).

Elytra with either costse or discal fovete, sometimes with l)oth (198-232).

Group VII.
Elytra without cost» or discal fovese (237-244) Group VIII.

The numbers in the tiible refer to the figures cm the accompanying
plates, the numbering being continuous for greater ease and ceilainty
of reference. Regarding the figures on the plates it must be remem-
bered that while many of the species are practically constant in
sculpture, others are greatly variable. Every figure represents the
sculpture of the specimen in hand at the time, that one being chosen
which seemed most closely to represent the average sculpture.

Group I.

In this group we now have six species, two of these were so placed
by Dr. LeConte, and I have added four others, three being for the
first time here described, Avhile the other had been placed in the series
with the disc of thorax unequal. Five of them agree in having the
thorax gradually narrowed to base, very feebly so in purpureovittata.
In Edirardsii, howevei', the thorax is broader at base and the sides
irregular. All agree in having the prosternum lobed in front, very
feebly in the larger species and quite prominently in the smaller
forms.

The following table will assist in separating the species :

Larger species ; the elytral costfe very distinctly elevated ; prosternal lobe rela-
tively feeble ; ventral segments with distinct lateral callosities.
Clypeus broadly emarginate.

Middle and posterior femora % and 9 coarsely serrate on their posterior

edges 1. atabalipa.

Middle a^id posterior femora simple 2. octocola.

Clypeus semi-circularly emarginate and with a tooth each side.

3. EdwaiHlsii.

72 GEO. H. HORN, M. D.

Smaller species ; the elytral costje either entirely obliterated or very faintly in-
dicated ; prosternal lobe very well marked ; ventral segments without
lateral callosities.
Sides of thorax arcuately narrowing to base ; sides of ventral segments
densely punctate and rather densely clothed with tine recumbent pu-
bescence.
Elytra with first costa faintly indicated and with indistinct discal fovea?.

4. (lebilis.
Elytra without trace of costse or foveas ; a large cupreous humeral space.

5. axillaris.
Sides of thorax straight and almost parallel ; abdomen sparsely punctate and
not pubescent.
Elytra without trace of costse. or fovea; ; usually blue or green, with a me-
dian purple-black vitta, surface shining 6. purpureovittata.

These species are all from the southwestern regions of our territory.
The serration of the femora in atabaUpa is a remarkable character
and has not been observed in any other species in our fauna.

tooth serrate on its entire edge ; the posterior edge of the lower
side of both the middle and posterior femora is coarsely serrate
in its entire extent. The first ventral segment is broadly sulcate at
middle, the following segments flattened.

There seems to be very little variation in this species. Usually the
first and second elytral costaj are alone distinct ; in some specimens,
however, there are traces of the third and fourth near the apex.

Female. — Front seneous or cupreous, more couvex, usually witli two chevrons
and sometimes a smooth median line in front ; antennae darker and less metallic
than in the male ; prosternum smooth at middle as in the male ; anterior femur
as in the male but less stout, the tibia less ai'cuate and not denticulate ; middle
tibia nearly straight, the posterior straight; last ventral segment (9) carinate at
middle, the apex truncate, with a slight tooth at middle, the angles prominent;
an intra-marginal serrate ridge ; last dorsal coarsely and densely punctate,
strongly carinate at middle and distinctly emarginate at apex.

In both sexes the first ventral segment is vaguely sulcate. There
have been no variations of moment observed in this species. On
comparison with ntabalipa its form is less elongate, the golden fovese
more evident and the emargination of the front rounded at bottom.

Occurs in Texas, Arizona, California and in Tamaulipas, Mexico.

larly emarginate at middle, on ,eaeh side dentiform ; anteuuse piceous, feebly
bronzed, third joint a little shorter than the next two, joints four to eleven grad-
ually narrower ; thorax more than twice as wide as long, sides feebly arcuate,
sinuate at middle, obliquely narrowing at apex, and slightly arcuately narrowing

tate, rather sparsely at middle, more densely and transversely wrinkled at the
sides; elytra very little wider than the thorax, very little more than twice as
long as wide, arcuately narrowing at apical third, the lateral margin serrate ; the
sutural margin elevated two-thirds to base, the first costa sharply elevated
three-fourths to base, the second nearly as long, the third less distinct, the fourth
very distinct in its apical half; the basal fovea deep, the humeral depression dis-
tinct, the discal fovea; existing in a faint trace, the inner about one-fourth from
the apex between the first and second costse, the second more anterior, interrupt-
ing the third costa ; intervals between the costte moderately, densely and very
regularly punctate ; body beneath coarsely and moderately densely punctured,
the ventral segments one to five with a smooth umbone at the sides. Length
.45 inch ; 11.5 mm. (Fig. 11.)

3Iale. — Unknown.

Female. -Front cupreous, convex, with two chevrons in the form of an inverted
V ; prosternum broadly smooth at middle, coarsely punctured at the sides ; an-
terior tibije slightly arcuate, the middle and posterior straight ; last ventral seg-
ment (13) nearly semi-circular, with a very feeble notch at tip, the margin ser-
rate ; a distinct submarginal line, within which is a feebly serrate elevation.

The prosternum is very distinctly lobed in front and the tooth of
the anterior femur is serrate along its entire outer edge from the
apex.

At first glance this species resembles some of the more robust
forms of femorata. It is, however, easily known from any other
species in our fauna by the form of the clypeus which seems peculiar.

Occurs at Tucson, Arizona ; Henry Edwards.

4. C. clebilis Lee. — Form moderately elongate, slightly convex, dark brown-
ish bronze, sometimes slightly feneous, sides of thorax usually broadly, bright cu-
preous ; antennse bright cupreous % or piceous 9 > gradually more slender to the
tip, the third joint as long as the next two ; front slightly convex, densely punctate,
more finely and more distinctly pubescent in the male, two distinct callosities, the
occipital carina sometimes bifurcate on the vertex ; clypeus with a moderately deep
oval emargination at middle arcuate each side ; thorax one and a half times as wide
as long, the base slightly narrower than the apex, the sides arcuate, broadest at
apical third, disc moderately convex, surface regular, without median or other
grooves or callosities, the punctuation a little variable, usually not dense, some-
times indistinct, but with distinct transverse strigse ; elytra a little wider than
the thorax, parallel, narrowed at apical third, the margins serrulate, the apices
obtuse ; first costa elevated near the apex, the others indicated by smooth lines,
more or less distinct, and usually interrupted ; basal fovea distinct but not deep,
two fovefe at apical third sometimes confluent, another in front of middle on the
second costal line, surface moderately closely punctured, more densely near the
base ; body beneath dark bronze, rather densely punctured, the sides of the ven-
tral segments densely and finely punctured and rather densely clothed with
white pubescence, the middle of the segments more coarsely and sparsely punc-
tured, a narrow space on each side of sutures two, three and four smooth and
shining; prosternum with a well defined lobe in front; anterior femur with a
moderately large, serrate tooth ; margin of last ventral segment serrulate.
Length ,20 -..32 inch : 5-8 mm. (Fig, 15.)

Hale. — Prosternum flat, densely, finely punctured and pubescent ; anterior
tibia (19) arcuate and with a short dilatation at apex ; middle and posterior tibiae
straight; last ventral segment (17) senii-circularly emarginate ; last dorsal
coarsely punctate, triangularly emarginate at apex.

Female. — Prosternum flat, more coarsely punctured and less pubescent than the
male; anterior tibia slightly arcuate, the middle and posterior straight; last
ventral (18* truncate, slightly emarginate; last dorsal coarsely punctate, entire.

While this species is rather inconspicuous in appearance it is as
easy to recognize as any in our fauna by the very well defined pros-
ternal lohe, the densely finely punctured sides of the abdomen with
the white pubescence and the elytral sculpture. I have examined
the types of debilis and dl^jnncta and find no appreciable difference.
They were originally described from uniques, but I have recently
examined more than twenty specimens. The elytral foveas are often
consjiicuously cupreous ; in the majority of specimens not so.

Occurs in Ohio (LeConte), Texas, Arizona and southern California.

5, C axillaris n, sp, — Form moderately elongate, not very convex, nearly
as in debilis, but broader ; color dark brownish bronze, the basal fovea of the
elytra and large humeral space, bright coppei-y red ; autennse more slender to the
tip, piceous, second joint as long as the next two ; front very slightly convex,
coarsely, closely punctate, two small tuberosities and a feeble chevron above ;
clypeus with a moderately deep oval emargination, arcuate each side ; thorax
twice as wide as long, base and apex equal, sides slightly irregularly arcuate, disc
moderately convex, without depressions or callosities, the surface rather sparsely

punctured at middle ; more densely at the sides ; elytra wider than the thorax,
parallel, arcuately narrowed at apical third, the margins serrate, the apices oh-
tuse, disc moderately convex, basal fovea distinct and bright cupreous, the first
costa faintly indicated behind the middle by a smooth line, the surface densely
punctured, more sparsely toward the suture and posteriorly; body beneath
nearly black, densely punctured, the ventral segments very densely punctulate
at the sides and clothed with fine white pubescence, at middle much more coarsely
punctured, the basal margins of the last three segments smooth, the terminal
segment with the margins serrulate ; prosternum very distinctly lobed in front ;
anterior femur with a moderately large tooth, serrate in its distal edge. Length
.31 inch; 8mm. (Fig. 20.)

Male. — Unknown.

Female. — Prosternum flat, densely and coarsely, almost cribrately punctured ;
anterior tibia (24) slightly arcuate, the middle and posterior straight ; last ventral
segment (23) with a very small, semi-circular notch at tip.

This species is closely allied by its prosternal lobe and the punc-
tuation of the abdomen to debilis, but ditt'ers from that species in the
almost total absence of elytral sculpture excepting the punctuation.
The ventral punctuation is also different, as the densely punctured
lateral region extends more to the middle and the median region is
more coarsely and closely punctate. The anterior tibi?e are bright
coppery red, Avhile the large humeral space is quite conspicuous.

One specimen, southern Arizona ; two from Texas a little more
brilliantly colored.

6. C. purpiireovittata n. sp.— Form moderately elongate, feebly de-
pressed, color bright blue or green, varying to violet or coppery bronze, each ely-
tron with a moderately broad purple-black vitta extending from the humeri
nearly to the tip, indistinct on the violet or bronze species, surface rather shin-
ing; antennfe cupreous, gradually more slender to the tip, the third joint very
little longer than the fourth ; front slightly convex, moderately densely punc-
tured, a slight arcuate carina near the top , clypeus rather broadly triangularly
emarginate, the notch oval at bottom, on each side arcuate , thorax about one
and a half times as wide as long, the sides straight and very slightly convergent
to base, anterior angles slightly rounded, disc moderately convex, surface regular
without inequalities, punctuation rather sparse at middle, den.ser and very
slightly strigose near the sides ; elytra a little wider than the thorax, parallel,
very slightly wider behind the middle, apical third rather obliquely narrowed,
the margin relatively coarsely serrate, the apices obtuse ; surface equal, without
costse or foveas, except the usual basal fovea and a moderate intra-humeral de-
pression, surface rather finely not closely, but quite evenly punctate ; body be-
neath similar in color to the upper surface, rather sparsely punctate, the ventral
segments without callosities, the margin of the last distinctly serrulate ; pros-
ternum very distinctly lobed in front; anterior femur with a small, very acute
tooth and a few denticulations more externally. Length .22- .29 inch ; 5.5-7.5
mm. (Fig. 25.)

Male. — Prosternum slightly convex, a little more coarsely and closely punctured
than the elytra; anterior tibia (29) slightly arcuate, a short and leather narrow

dilatation at apex ; middle and posterior tibiae straight ; last ventral segment (27)
semi-circularly emargiuate ; last dorsal coarsely, sparsely punctate, slightly
notched at middle.

Female. — Presternum as in the male ; anterior tibia very slightly arcuate, the
others straight ; last ventral (28) sinuately truncate ; last dorsal coarsely punc-
tate, the apex entire.

In the bright blue or green specimens the extreme margin of the
thorax as well as the entire lateral margin of the body beneath and
the femora are bright cupreous. The brightly cplored specimens
with the more distinct blackish vitta are very pretty and easily
known, the darker forms by their color and form resemble seitiUa at
first glance.

Occurs in Indiana, Illinois, Kansas and Texas, the latter region
being most numerously represented.

Group II.

The group here separated is characterized by having the disc of
the thorax irregular, more or less sulcate at middle, the last ventral
segment with serrulate margin. The clypeus is acutely incised at
middle, semi-circular each side and it may be aptly compared to two
semi-circles tangent with their diameters continuous. The anterior
tibiae of the male are arcuate, the inner edge multi-denticulate and
the middle tibiae are similar. The form of the two pairs of tibise is
repeated in sexdgnata which has also a similar clypeus, but more
broadly emarginate, but the last ventral segment has the lateral
margin entire.

There is but one species known which can be referred to this group,
but what the group lacks in number is made up in the variation of
that one species and is without parallel in our series.

7. €-. foinoratst Fab. — Form oblong, sometimes slightly robust or moder-
ately elongate, usually of dark bronze surface, but sometimes slightly brassy,
cupreous, or rarely seneous ; antennse serrate from the fourth joint and gradually
more slender to the tip, the third joint a little longer than the next two; green-
ish % or cupreous 9 ; front rather flat % or slightly convex 9 ^^d ^Jth a
chevron in both sexes and other callosities 9 ; clypeus (31) at middle acutely
notched, on each side semi-circular ; thorax more than twice as wide as long,
widest slightly behind the apex, the sides somewhat irregular, slightly narrowed
at base ; disc irregular, an indistinct median depression, a deeper depression pos-
terior to and parallel with the apical margin, with other irregular depressions
near the side ; surface rather coarsely punctured less densely at middle, more
densely and deeply at the sides ; elytra a little wider than the thorax, sides
nearly parallel, gradually narrowed at apical third, the margin serrate, the apices
obtuse ; disc feebly convex, the sculpture very variable, usually with the first

and second costfe distinct near tlie apex, and with two fovese on each side, which
are transverse in form, the tirst a little in front of middle, the second one-third
from apex, the basal depression father feeble, the surface otherwise coarsely and
near the sides conflueutly punctured ; body beneath more shining than above
and more metallic, usually more or less greenish in the % or cupreous 9 , the
surface coarsely but not densely punctured, the ventral segments with a trian-
gular umlxnie on each side ; presternum not lobed in front, the surface coarsely
punctured at the sides and with a smooth broad line at middle, hairy in the % ;
anterior femur with a rather broad, obtuse tooth, the entire margin of which is
serrate. Length .28- .64 inch ; 7- 16 mm. (Fig. 30.)

Male. — Front usually green, hairy ; anterior tibise (34) arcuate, slightly dilated
at tip, the inner margin with small teeth, usually five, sometimes more, rarely
serrulate ; middle tibise arcuate, the inner margin serrulate, except near the
base; iiosterior tibite straight; last ventral segment (32) with the margin serru-
late, a submarginal depression, the apex semi-circularly emarginate ; last dorsal
segment coarsely, sparsely punctate, the apical border emarginate.

Female. — Front cupreous, never green, not hairy; anterior tibiae arcuate,
slightly broader at tip, not serrate or toothed internally ; middle tibive slightly
arcuate, inner margin simple ; posterior tibiae straight; last ventral segment (33)
more elongate than in the male, the apex broadly but feebly emai-ginate, the
angles sometimes slightly prominent; last dorsal strongly carinate at middle,
the apex truncate.

As might be expected Avith a species of such wide distriliution the
variations in aspect and in sculpture are very great, but with a large
series the specific identity of all the forms is easily demonstrable.
The essential characters of the speckles remain the same through all
its variations and may be summarized as follows ; last ventral seg-
ment with serrulate margin ; thorax with irregular surface ; clypeus
acutely notched at middle and semi-circular each side; anterior tibias
of male slightly dilated at tip, the inner side denticulate.

The form of the clypeus is peculiar to the s])ecies, the only ap-
proach to a similarity being in sexdg}iata, which has the margin of
the last ventral simple. The variations of sculpture have given rise
to the descriptions of many of the forms under different specific
names, the most important of which will be briefly noted.

C. Alabamce Gory. — This is the larger and more robust form oc-
curring in the Gulf States. The sculpture is quite coarse, but the
elytral costae are hardly indicated. The fovefe of the disc are well
marked and usually coj^pery.

C. femorata Fab. — Is the form more common in the Middle States,
and in size it is somewhat smaller and less robust than Alabamce, the
sculpture smoother, the elytral cost® a little more evident, and the
foveae more sharply limited.

NORTH AMERICAN COLEOPTERA. 79

C. soror Lee. — Tliis is a little sniootlier and more slender, the
thorax more decidedly narrowed at base, the elytral costae without
being much elevated are more distinct for a greater length.

(J. Lesueuri Lap. et Gory. — In this form, which resembles soror in
shajie, the elytral sculpture is quite sharply indicated and the costae,
foveas and more densely punctured intervals are well limited. The
foveae are especially sharply defined and are usually more golden in
color.

C. nigritula Lap. et Gory, (ohscura Lee.) — Form slender, rather
more acutely narroAved posteriorly, the surface more greenish from
the color of the punctures and the sculpture even more confused than
in Alabamce.

C. misella Lee. — This form is founded on small and imperfectly
developed specimens and from their sculpture and general appear-
ance should be referred to the variety femorata.

Other variations will be observed in the color of the under side of
the body from brassy to cupreous and green, but as these are so com-
mon everywhere in the Buprestidee it is merely necessary to indicate
their occurrence.

As already remarked the species has a very wide distribution. It
occurs in Canada and in every State and territory in the United
States and extends into Mexico.

Group III.

The group here suggested consists of species of at most moderate
size, without very conspicuous or well defined elytral sculpture. The
thorax has a rather feeble median impression, almost Avanting in
ignicollis and contigua, being therefore intermediate between the spe-
cies of the first group and those aggregated around trinervia. The
last ventral segment has a serrate margin. The essential character
of the group is found in the anterior tibia of the male, which has an
acute tooth (in contigua obtuse) usually one-third from the apex,
although in speculifer and virldicyanea it is very close to the apex.

The following table gives, in brief, the characters separating the
species :

Clypeus acutely incised at middle, dentate each side.

Clypeal teeth well marked ; tooth of anterior tibia % rather broad, not veiy

acute at tip - 8. contigua.

Clypeal teeth scarcely prominent; tooth of anterior tibia male acute and
prominent 9. cuprascens.

80 GEO. H. HORN, M. D.

Clypeus with a truncate median lobe, a slight sinuation on each side ; anterior

tibia % as in cuprascens 10. floi'ieola.

Clypeus with an oval or broad emargination at middle.

Color coppery bronze, or some slight variation of that.

Tooth of anterior tibia % slender, acute and one-third from the apex.

11. ignicollis.
Tooth of anterior tibia % triangular, very near the tip. .12. speculifer.
Color bright blue or greenish ; tooth of anterior tibia % rather large, trian-
gular and acute, very near the apex 13. Tiridioyanea.

The species of this group, with the exception of floricola, belong
to the region of Colorado and Texas, westward to California and
Oregon.- The first mentioned {florkohi) belongs to the Atlantic
region proper.

8. C'. eoiitigiia Lee. — Moderately elongate, subdepressed ; color above dark
bronze, moderately shining ; thorax somewhat cupreous, beneath usually cupre-
ous; antenuse gradually more slender to tip, with greenish % or cuxireous 9
lustre, third joint as long as the next two; front flat and densely punctured,
greenish and pubescent % or slightly convex, less densely punctured, cupreous
and not pubescent 9 \ clypeus (36) with a small acute notch at middle, on each
side a small acute tooth and sinuate ; thorax twice as wide as long, base and apex
equal, sides obliquely narrowed at apex, nearly parallel at middle, then slightly
narrowed at base; disc rather uneven, median depression feeble, with a distinct
impressed line posteriorly, post apical transverse impression distinct; surface
coarsely and not densely punctured" at middle, more densely, almost cribrately
punctured at the sides ; elytra wider than the thorax, parallel, narrower at apical
third, the margin serrulate, the apices obtuse ; surface irregularly sculptured, the
first eosta distinct at apical half, the others confused, intervals coarsely, densely
punctured, with an irregular smoother space behind the middle, a second near the
apex, basal and humeral depressions distinct ; prosteruum distinctly but feebly
lobed in front ; body beneath shining, coarsely not densely punctured ; anterior
femur with a small tooth, not visibly, serrate. Length .28 - .42 inch ; 7 - 10.5 mm.
(Fig. 35.)

Male. — Prosternum very densely punctured, sparsely pubescent ; anterior tibiae
(39) slightly arcuate, a little thicker at tip and with a broad, rather obtuse tooth
below the middle ; middle and posterior tibise straight ; last ventral segment (37)
with serrulate margin, the ajiex with a small semi-circular emargination; last
dorsal sparsely punctate, apex emarginate.

Female. — Prosternum coarsely not densely punctate ; anterior tibiae slightly
arcuate not dilated nor toothed ; middle and posterior straight ; last ventral seg-
ment (38) with serrulate margin, and with a very small emargination at tip; last
dorsal very coarsely punctate and entire.

This species shows very little variation in the color of its surface,
but the sculpture is slightly variable and difficult to describe without
being individual. In appearance it resembles some of the forms of
femorata. With this species begins a small series in which the male
has the anterior tibia toothed at some point below the middle, of

NORTH AMERICAN COLEOPTERA. 81

these two only have the form of clypeus described above ; the present
species has the tibial tooth slightly below the middle and obtuse,
while in cnprascens it is one-third from the apex and acute.

Occurs in Oregon, Washington Territory, Nevada and California.

9. C ouprasceiis Lee. — Form of femorata, subdepressed, cupreo-seneous,
the thorax more reddish, moderately shining; antennte more slender at tip,
greenish % or feneous 9 > third joint as long as the next two ; front feebly con-
vex, without callosities, more densely punctured and greenish % ; clypeus (41)
triangularly notched at middle, on each side acutely toothed, then subtruncate ;
thorax twice as wide as long, base and apex equal, sides in front narrowing, at
middle parallel, slightly sinuate, base slightly narrowed ; disc irregular, a vague
median depression and with slight depressions near the side ; surface coarsely
and moderately closely punctate, subconfluent near the sides ; elytra wider than
the thorax, the sides parallel, or slightly sinuous, naiTOwing at apical third, the
margin serrulate, the apices obtuse ; the first costa distinctly elevated, extending
two-thirds to base, the second and third costse feebly evident at middle ; basal
fovea moderately deep, discal foveas two on each side, the first irregularly quad-
rate near the middle between the first and third costse,, the second one-third from
the apex transverse, the fovese very densely and finely punctured, the surface
otherwise irregularly punctured, densely and coarsely punctured at sides and
apex, more sparsely on the disc; body beneath coarsely not densely punctate ;
last ventral segment serrulate ; anterior femur with a small tooth not serrulate.
Length .26-36 inch ; 6.5-9 mm. (Fig. 40.)

3Iale. — Prosternum very densely punctured, finely pubescent ; anterior tibiae
(44) slightly arcuate, acutely toothed one-third from the apex ; middle and pos-
terior tibise straight ; last ventral segment (42) with a small, semi-circular emar-
gination ; last dorsal obsoletely punctate, apex subtruncate.

Female. — Prosternum coarsely and closely punctate ; anterior tibise slightly
arcuate, simple, the middle and posterior straight; last ventral (43 j with a very
small emargination at apex ; last dorsal sparsely punctate at the sides, the apex
entire.

With a form of clypeus similar to that of eontigua this species
differs in the form and position of the anterior tibial tooth of the
male. The sculpture of the surface is more distinctly defined and
the shallow fovese quite well indicated. There seems to be very little
variation m the numerous specimens examined.

The unique type in the cabinet of Dr. LeConte has the clyjoeus
without the two median teeth as I have indicated in a previous paper
(Trans. Am. Ent. Soc. pi. iv, fig. 16) ; this seems, however, purely
accidental, as my specimens otherwise agree so closely in form, color,
sculpture and sexual characters.

Occurs in Colorado and New Mexico.

10. <'. florieola Gory. — Form oi femorata, subdepressed, dark bronze, with
slight cupreous tinge; antennae very little more slender toward the tip, aneous

9 or greenish % , third joint a little longer than the next two ; front slightly

convex in both sexes, coarsely, densely punctured, with small, irregular callosi-
ties; clypeus (46) with a short, median, truncate lobe, on each side of which is a
slight sinuation ; thorax more than twice as wide as long, the sides nearly par-
allel at middle, narrowed at apex and base ; disc irregular, a distinct median chan-
nel, wider in 9 , and some irregular depressions near the side, a subcariniforni
callus at base opposite the middle of each elytron ; surface coarsely punctate, not
densely at middle, very densely and confluent at the sides ; elytra wider than the
thorax, often wider slightly behind the middle, gradually narrowed at apical third,
the margin serrulate, the apices obtusely rounded ; the first costa moderately ele-
vated from the apex to the middle, the other costa very indistinctly defined and
irregular, the basal and humeral depressions not deep, surface very densely i)unc-
tured between the slight elevations, more sparsely near the base ; body beneath
sparsely punctate, very shining; prosternum distinctly lobed in front; last ven-
tral segment with serrulate margin ; anterior femur with rather strong tooth,
serrulate on its distal edge. Length .34 - .48 inch ; 8.5 - 12 mm. (Fig. 45.)

Male. — Prosternum coarsely, sparsely punctate at the sides, scarcely hairy ; an-
terior tibia (50) slightly arcuate, with a very acute and prominent tooth one-third
from the tip ; middle tibia slightly arcuate, the inner side slightly sinuous and
subangulate one-third from the apex ; posterior tibia straight ; last ventral seg-
ment (47) with a very feeble emargination at apex ; last dor.sal coarsely punctate,
the apical margin subtruncate.

Female. — Prosternum as in the male ; anterior tibia feebly arcuate, inner mar-
gin simple ; middle and posterior tibise straight ; last ventral segment (48) longer
than in the male, subtruncate at apex ; last dorsal very coarsely punctate, apex
entire.

While there is very little noteworthy in the general ai)j)earance of
this species, it is unique in the form of the clypeus being the only
one in our fauna without emargination. The form of the middle
tibia of the male is also unique.

Occurs from the Middle Btates to Florida.

11. C ignieollis Horn. — Form nearly that of the smaller femorata, but
rather broader, color dark bronze, the head and thorax bright cupreous ; antennse
rather short, seneous %, piceous 9> serrate from the fourth joint but scarcely
narrower externally, third joint as long as the next two ; front slightly convex,
more densely punctured in the male ; clypeus (52) with a rather shallow, broad
emargination at middle ; thorax twice as wide as long, sides at middle parallel
and slightly sinuate, narrowed at apex and base ; disc feebly convex, a vague
median depression with others irregular near the sides and apex ; surface moder-
ately coarsely punctured, the punctures sparse and rather irregular at middle,
dense and confluent at the sides ; elytra a little wider than the thorax, parallel,
narrowed at apical third, the margin serrulate, the apices obtuse ; disc feebly con-
vex, the first costa extending from apex to middle, the discal fovese shallow,
transverse, densely punctured, the basal fovea deep, the surface between the discal
fovese and posterior to the last very sparsely punctured, the surface otherwise
coarsely and densely punctured ; body beneath bright aeneous or subcupreous,
coarsely, sparsely punctured, rather more densely at the sides of the ventral seg-
ments ; last ventral segment with serrulate margin ; anterior femur with rather
small, obtuse tooth, serrate along its distal margin. Length .24 - .32 inch ; 6-8
mm. (Fig. 51.)

NORTH AMERICAN COLEOPTERA. 83

Male. — Prostenium not lobed in front, coarsely, densely punctured, with a feeble
trace of smooth median space, sparsely puliescent ; anterior tibia (55) slightly ar-
cuate, and with a very acute tooth one-third from the tip ; middle tibia slightly
sinuate on the inner side; last ventral segment (53) broadly, almost semi-circu-
larly emarginate ; last dorsal sparsely punctured.

Female. — Prosternum coarsely, sparsely punctured, the median smooth space
evident; anterior tibia slightly arcuate, middle and posterior straight ; last ven-
tral segment (54) with a very small emargination at apex ; last doi-sal very coarsely
densely punctured.

The general style of elytral sculpture is that of contigua, cupras-
cens and speculifer, and in aspect it resembles especially the second.
The form of the clypeus will distinguish it from the first two while
the form and position of the anterior tibial tooth of male will sepa-
rate it from the third. It is almost impossible, in description, to
separate the females of speculifer and ignkoJUs.

Occurs in Colorado and Texas.

12. C. speculifer n. sp. — Form oblong, subdepressed, as in the var. misella
of femorata, bright cupreo-seneous, usually more red posteriorly; antennee piceous,

tate, continent near the sides ; elytra a little wider than the thorax, parallel, nar-
rowed at apical third, the margin posteriorly feebly serrate, the apices separately
rounded ; disc subdepressed, the first costa distinctly elevated from apex to middle,
two more densely punctured discal fovese of large and irregular form, the one at
apical third the other in front of middle, the basal fovea deep, and with elevated
spaces conspicuously shining and smooth, the surface otherwise rather densely
and coarsely punctured ; body beneath very coarsely not closely punctate, the
ventral segments with distinct callosities at the sides ; prosternum not lobed in
front, coarsely, closely punctate in both sexes with feeble, smooth, median line ;
anterior femur with moderate tooth serrate on its distal margin. Length .24- .28
inch; 6-7 mm. (Fig. 56.)

Male. — Anterior tibia (60) feebly arcuate, slightly broadened at tip and with an
acute tooth near the apex ; middle tibia slightly arcuate, the posterior straight ;
last ventral segment (58) semi-circularly emarginate.

Female.— Anterior tibia slightly arcuate, without notch ; the middle and poste-
rior straight ; last ventral (59) with a very small emargination at tip.

With a similai-ity of surface sculpture to the other members of the
group with toothed auterior tibia, this species is notable in having

the smooth spaces more sharply limited and more shining. The es-
pecial distinction is, however, based on the form of clypeus and the
male sexual characters.

Occurs in Colorado and Arizona.

changing to green ; antennse green, more slender externally, third joint as long
as the next two ; front feebly convex, rather densely punctured and with two
feeble callosities ; clypeus (62) with a feeble, triangular emargination at middle
on each side arcuate ; thorax more than twice as wide as long, nearly parallel at
middle, narrowed at apex and base ; disc feebly convex, a vague, median, and
some irregular lateral depressions ; surface coarsely punctate, sparsely at middle,
more densely and subconfluently at the sides ; elytra broader than the thorax, a
little wider behind the middle, arcuately narrowing at apical third, margin feebly
serrate posteriorly, the apices separately obtuse ; the first costa distinctly elevated
from apex to middle, the basal fovea deep, the surface rather coarsely and densely
punctured, very irregularly in places with transverse smoother spaces at apical
third, behind the middle and obliquely from the humeri ; body beneath more
shining than above, coarsely but sparsely punctate ; prosternum not lobed ; last
ventral with serrulate margin ; anterior tibia with feeble tooth, serrate on its
distal edge. Length .32- .36 inch -,8-9 mm. (Fig. 61.)

ilffflZe.— Prosternum very densely punctured and pubescent; anterior tibia (65)
slightly arcuate, a slight dilatation one-third from base, a strong acute tooth near
the apex ; middle tibia slightly sinuous within, the posterior straight ; last ven-
tral segment (63) deeply semi-circularly emarginate, the last dorsal coarsely punc-
tate and feebly emarginate at apex.

Female. — Prosternum coarsely, moderately, closely punctate ; anterior tibia
feebly arcuate; middle and posterior straight; last ventral (64) longer than in
the male, feebly but rather broadly emarginate ; last dorsal closely punctate,
subtruncate.

This species has a general superficial resemblance to Harrisii, but
is more densely punctate and less shining. The two species differ
primarily in their sexual chai'acters.

Occurs in California, Nevada and Montana.

Group IV.

This group contains nearly one-third of all the species in our fauna,
and is of very difficult study, and from the similarity of the elytral
sculpture in seven of the species it is necessary to have recourse to
sexual characters. The species divide themselves into two equal
series — those Avith the prosternum lobed in front and those with the
prosternum truncate. The lobe is here never so well marked as has
been observed in several other groups, and in fact in several species
consists of a mere arcuatiou of the anterior margin of the proster-

This group has representation in every part of our fauna and two

other species are more restricted in their habitats.

14. V. Harrisii Hentz. — Form rather broad, subdepressed ; color blue, or
greenish liluo, shining, beneath similar in color, but usually darker ; antenna;
piceous, slightly more slender to tip, third joint not as long as the next two,
sometimes hardly longer than the fourth ; front slightly convex, a little more
punctate in the male and somewhat more green ; clypeus (67) with a broad, shal-
low emargination at middle, arcuate each side ; thorax a little more than twice
as wide as long, obliquely narrowed at apex and base, slightly sinuate at middle,
disc moderately convex, a vague depression of the median line ; surface some-
what irregular, coarsely and closely punctured, transversely strigose near the
sides ; elytra wider than the thorax, slightly wider behind the middle, disc feebly
convex, the first and fourth costfe slightly elevated near the apex, basal depres-
sion deep, the humeral slight, a large shallow fovea one-third from base on the
line of the second costa, frequently another le.ss distinct one-third from apex,
surface rather coarsely and roughly punctured ; body beneath moderately
coarsely, but not densely punctured, the ventral segments without lateral cal-
losities, the posterior angles not prominent, the last ventral with serrulate mar-
gin ; anterior femur with a moderate and rather obtuse tooth, feebly serrate ;
prosternum not lobed in front. Length .24- .32 inch ; 6 -8 mm. (Fig. 66.)

Male. — Prosternum tlat, densely punctured ; anterior tibiae (70) arcuate, slightly
dilated at apex, sinuate above the dilatation ; middle tibia arcuate, very obliquely
grooved, posterior tibia straight; last ventral segment (68) semi-circularly emar-
ginate ; last dorsal coarsely punctate, triangularly notched at apex.

Female. — Prosternum very coarsely punctate; anterior tibia slightly arcuate,
the middle less so, the posterior straight ; last dorsal (69) longer than in the male,
a very slight notch at tip; last dorsal coarsely punctured, the apex entire.

This species has heretofore been placed among those in which the
htst ventral segment has an entire border, but in all the specimens
examined it is distinctly serrulate, its place is therefore in the ])resent
series. The only species at all closely resembling it is viridicyanea,
which has other sexual characters.

New England States and Canada, extending as far south as North
Carolina.

NORTH AMERICAN COLEOPTERA. Ql

15. i\ dolata u. sp. — Form rather broad, as depressed as in dentipes, color
piceous or nearly black, with faint bronze lustre, beneath cupreous; antennfe
cupreous, gradually more slender to the tip, the third joint a little longer than
the next two ; front ( 9 ) cupreous, coarsely and closely punctate, with two cal-
losities at middle ; clyiseus (72) with a triangularly oval emarginatiou at middle
on each side arcuate ; thorax twice as wide as long, sides strongly arcuate near
the front angles then feebly arcuately narrowing to base ; disc feebly convex
not sulcate at middle, a moderately deep crescentic depression each side, an ob-
lique depression near the apex, a feebly elevated ridge near the sides, surface
very densely, rather coarsely punctate, the punctures slightly transversely con-
fluent ; elytra wider than the thorax, rapidly narrowed at apical third, the mar-
gin serrulate, the apices obtuse ; disc with the first costa entire, the second and
third interrupted and transversely confluent into large, smooth, elevated spaces,
the fourth costa fine and submarginal, the intervals very densely i)unctured and
opaque ; body beneath cupreous, moderately closely punctate ; prosternum not
lobed in front, coarsely and closely punctate 9 ; la^^t ventral segment with ser-
rulate margin ; anterior femur with moderately strong, serrulate tooth. Length
.46 inch; 11.5 mm. (Fig. 71.)

Male. — Unknown.

fema/e.— Anterior and middle tibise feebly arcuate, the posterior straight; last
ventral segment (73) very feebly emarginate at apex ; last dorsal sparsely punc-
tate, acutely notched at apex.

Not having the male of this species its position in a tabular ai'-
rangenient is somewhat uncertain, but the absence of prosternal lobe
restricts its position between those in which the male have a tibial
tooth or those with an apical dilatation. The form of the thorax,
the emargination of the clypeus and the peculiar elytral sculpture
will make it recognizable. The contrast on the elytra between the
elevated smooth spaces and the densely punctured intervals is very
striking.

Occurs in California, Nevada and Oregon, and is thus far rare.

16. C dentipes Germ.— Form moderately elongate, depressed, color dark
bronze, either brownish or piceous, very feebly shining : antenuie more slender
externally, joint three nearly as long as the next two, joints four to eleven in
great part testaceous ; front flat and densely punctured, without distinct callosi-
ties % , or slightly convex, irregularly, coarsely punctured, with more or less
distinct callosities 9 ; clypeus (76) rather broadly, triangularly notched at mid-
dle, on each side rounded ; thorax nearly twice as wide as long, broadest one-
third from apex, the sides posteriorly slightly sinuate and gradually narrowed
to base ; disc moderately convex, a broad median sulcus wider in front, limited
on either side by a more elevated smoother space, between which and the margin
the surface is irregular; surface densely punctate and at sides confluent; el;si:ra
wider than the thorax, nearly parallel, obliquely narrowed at apical third, the
margin feebly serrate, the apices separately obtuse ; disc rather flat, the fir.st co.sta
distinct at apical half terminating in front in a vague, smooth space, the other
costa^ replaced by broad smoother spaces of irregular shape, the surface between
very densely punctured, the basal fovea moderate ; body beneath cupreous.

coarsely not closely punctate ; prostcrnum (98) not lobed in front ; anterior femur
with a rather strong but obtuse tooth, serrate on its distal edge ; last ventral
segment with serrulate border. Length .40- .64 inch ; 10-16 mm. (Fig. 75.)

3Iale. — Prosternum very sparsely punctate, more densely and finely along the
anterior border; anterior (79) and middle tibiaj arcuate and slightly dilated near
the apex, the posterior very feebly arcuate; last ventral segment (77) broadly,
nearly semi-circularly emargiuate : last dorsal coarsely not densely punctate,
emarginate at apex.

Female. — Prosternum as in the male : anterior and middle tibiae feebly arcu-
ate, the posterior straight; last ventral (78) longer than in the male, a feeble
emargination at apex ; last dorsal coarsely punctate at apex and with a .small
emarginatiou.

Notwithstanding the wide distribution of this species it shows so
very little variation except in size and surface color, that there will
be no trouble in recognizing it. It is remarkable in having the outer
joints of the antennae yellowish testaceous in both sexes, a similar
structure will be observed in the male of prolonr/afa. The anterior
and middle tibite of the male are almost exactly alike, a condition
very unusual in the genus. Superficially the sculpture is somewhat
like floricola.

Occurs in Canada and all the States east of the Mississippi and
trom Missouri westward to Nevada and Oregon. I have never had
specimens from Texas, Arizona, New Mexico or California.

17. C Itiflificata n. sjj. — Form moderately elongate, very little convex,
piceous or nearly black with the densely punctured spaces cupreous, body be-
neath dark bronze ; antennae (96) bronze, joints four to eleven serrate and equally
broad, third as long as the next two ; front very slightly convex, coarsely punc-
tate, with more elevated tubercles; clypeus (81) very broadly triangularly emar-
ginate, on each side slightly arcuate ; thorax nearly twice as wide as long, the
sides in front and posteriorly oblique, at middle slightly sinuate ; disc moderately
convex, a rather deep, median, densely punctured sulcus limited each side by an
irregular co.sta, the surface thence to the sides coarsely and confluently punctured
and with two smoother tubercles; elytra a little wider than the thorax, parallel,
narrower at apical third, the margin serrulate, the apices obtuse ; disc with the
usual four costse, the first nearly entire and straight the others interrupted and
irregular, the intervals with alternating smooth and densely punctured spaces,
the latter cupreous ; body beneath very shining, sparsely punctate, dark bronze,
sometimes slightly greenish at middle ; prosternum truncate in front, coarsely
punctate in both sexes, but smoother at middle in the female ; last ventral seg-
ment with serrulate margins ; anterior femur strongly toothed, the tooth serru-
late on its outer edge. Length .40 -.48 inch ; 10- 12 mm. (Fig. 80.)

Male. — Anterior tibiae. (84) slightly arcuate, an obtuse dilatation at tip, an ob-
lique groove above the dilatation extending along the front of the tibia in front
of the dilatation ; middle tibia feebly arcuate and slightly thickened below the
middle ; posterior tibia straight; last ventral segment (82)' semi-circularly emar-
ginate, a vague median depression ; last dorsal coarsely punctate, emarginate at
tip.

NORTH AMERICAN COLEOPTERA. 89

Female. — The tibiae nearly straight, the anterior not dilated ; last ventral (83)
longer than in the male and with a small semi-eircular notch ; last dorsal coarsely
punctate, feebly emargiuate.

This species is one of a small group in which the markings are
very similar, and consequently difficult to distinguish, except by other
characters, principally sexual. The present species is notable in
having the joints of the antenme from the fourth to the tenth of
equal width, the usual form is more slender externally. The male
is ])eculiar in not having the prosternum very differently sculptured
from the female, the usual punctuation is denser and finer.

Occurs not uncommonly in Colorado. I have seen others in the
cabinet of Mr. Ulke from New Mexico, Arizona and California.

18. C scabripeiinis Lap. et Gory. — Form offemorata, a little more acute
posteriorly, color brassy or slightly cupreous ; antennse more slender externally,
greenish blue % or subcupreous 9- third joint as long as the next two; front
rather flat, densely punctate and green % , or slightly convex, more coarsely
punctate and more or less cupreous 9 - callosities in both sexes ; clypevis (86) very
broadly not deeply triangularly emarginate at middle, on each side rounded ;
thorax twice as wide as long, narrowed at apex and base, sides at middle nearly
parallel, disc moderately convex, a vague median channel densely punctured,
wider in front, limited each side by a slightly elevated smooth space, between
which and the sides the surface is irregular, very coarsely and confluently punc-
tate, forming transverse plicae ; elytra wider than the thorax, parallel, narrowed
at apical third, the margin serrulate the apices separately obtuse ; disc slightly
convex, the four costae distinct, but more or less interrupted and with anasto-
mozing lines, the surface densely, moderately, finely punctured, the basal fovea
rather feeble ; body beneath coarsely not densely punctate, the metasternum more
densely and finely ; prosternum not lobed in front ; anterior femur with a mod-
erately strong tooth crenulate on its distal margin ; last ventral segment with
serrulate margin. Length .34 -.42 inch ; 8.5 -10.5 mm. (Fig. 85.)

Male.— Prostevnum. moderately, densely and rather coarsely punctate, sparsely
pubescent ; anterior tibia (89) arcuate, moderately dilated at apical fourth ; middle
tibia arcuate, slightly broader near the apex, the posterior arcuate ; last ventral
segment (87) semi-circularly emarginate; last dorsal coarsely punctate feebly
emarginate at apex.

Female. -Prosternum coarsely and much more sparsely than in the male; an-
terior and middle tibife feebly arcuate, the posterior straight; last ventral (88)
with a very small semi-circular emargination ; last dorsal coarsely and densely
punctate, the apex emarginate.

The color of the under surftice may vary from aeneo-cupreous to
greenish. I have seen a specimen from the Museum of Comj)arative
Zoology (juite green above. From all the other species of the group
which follow (with truncate i)rostei-num) this nmst be distinguished

primarily by the male sexual characters ; secondarily it will be ob-
served that the thorax here is shorter and more abruptly narrowed
at base.

Occurs in Canada, New York and the New England States.

19. C triiiervia Kby. — Form nearly that of femornfa, subdepressed, pice-
ous, with aeneous surface lustre, the punctured spaces of the elyti'a cupreous, body
beneath cupreous; antennee bronzed, gradually more slender to tip, third joint
as long as the next two ; front green, rather flat % , cupreous, slightly convex 9 ,
coarsely and closely punctured, with two small callosities; clypeus (91) broadly
triangularly emarginate at middle, the notch sometimes oval at bottom, on each
side arcuate ; thorax twice as wide as loug, sides rather abruptly wider in front,
then slightly convergent and near the hind angles abruptly narrowed, but less
so than in front ; disc moderately convex, a moderately deep median sulcus
densely punctured, on each side an ii-regular elevation, near the sides usually
with two tubercles placed obliquely, the surface otherwise densely and coarsely
punctured ; elytra parallel, narrowed at apical third, the margin serrulate, the
apices obtuse ; disc subdepressed, with three more or less interrupted costse. with
intercurrent elevations, the fourth costa close to the margin and inconspicuous ;
intervals between the costfe with alternating, densely punctured, and smoother
spaces ; body beneath sparsely punctate ; prosternum not lobed in front ; anterior
femur with a broad but obtuse tooth, feebly serrate on its outer edge ; last ven-
tral segment with the margin serrulate. Length .36 - .56 inch ; 9-14 mm.
(Figs. 90 and 95.)

Male. — Prosternum very densely punctured and finely pubescent ; anterior
tibia (94) arcuate, riither abruptly dilated at tip, the dilatation being a lamina
arising from the posterior side of the tibia; middle tibia less arcuate, gradually
broader to tip, the posterior tibia straight; last ventral segment (92) broadly
semi-circularly emarginate, the last dorsal sparsely punctate with a triangular
emargination.

Female. — Prosternum coarsely, sparsely punctate ; anterior tibia slightly arcu-
ate, gradually wider to tip, the middle less arcuate, not thicker, the posterior
straight ; last ventral (93) longer than in the male and with a small semi-circular
emargination ; last dorsal more punctate than in the male, a vague median sul-
cus and a small apical notch.

As is usual in a species with wide distribution the facies is ex-
tremely variable. This results from the greater or less i)rominence
of the costse and their extent as well as from the variable j^unctua-
tion. From the aggregate, which has heretofore passed as trinervia
in (>ur cabinets, I have separated a number of species — some of which
follow immediately — others belong to the series with the prosternum
feebly lobed in front. These differ in their sexual characters in ad-
dition to the presence of the lobe. There remains, notwithstanding,
the separation of these, an aggregate of variable facies with all inter-
grades of form and sculpture, which must by their sexual characters
be considered trinervia. It will therefore be necessary in examining
specimens to look closely to the sexual characters.

NORTH AMERICAN OOLEOPTERA. 91

111 the more iiortlieru specimens (from New England States,
Canada and northward) the individuals are usually smaller and with
the elytral costae well marked often entire, the thorax is also often
slightly narrowed from the post apical dilatation to the base, while
in the southern and western forms the thorax is in shape quite like
femorata. The color beneath is always brassy or cupreous, those
mentioned by LeConte as entirely green beneath belong to ccmrina
or carmipennis.

Occurs from the Hudson's Bay region through Canada and the
New England States as fer south as North Carolina ; from the Mid-
dle States it extends westward to Colorado, New Mexico, thence to
Utah, and to Alaska. I have never seen specimens from our Pacific
States.

20. C. cariiiipennis Lee. — Form rather more elongate than femorata,
piceous, the ]iunctured spaces dark bronze or coppery, body beneath either sene-
ous or sometimes entirely green ; antenuse aeneous in both sexes, gradually more
slender to the tip, third joint as long as the next two; front rather flat %,

allel, gradually narrowed at apical third, sides feebly serrulate, apices obtuse,
disc feebly convex, the first costa nearly entire, the second and third distinct but
interrupted by the punctured spaces, the fourth finely elevated, intervals with
alternating densely punctured and smooth spaces conjointly of nearly equal
areas, the basal fovea not deep ; body beneath not densely punctured, the punc-
tures somewhat elongated , prosternum not lobed in front ; anterior femora with
a moderate tooth very feebly serrulate on distal edge ; last ventral segment with
serrulate margin. Length .36- .50 inch ; 9-12.5 mm. (Fig. 100.)

Male. —Prosternum coarsely and moderately densely punctured, sparsely pubes-
cent; anterior tibia (104) arcuate and with a deep sinuation one-third from the
apex and a dilatation from the posterior border of the tibia from the emargina-
tion to the apex ; middle tibia slightly arcuate and feebly dilated at tip, the pos-
terior straight ; last ventral segment (102) deeply semi-circularly emarginate, the
last dorsal moderately punctate, feebly emarginate at apex.

middle ; anterior and middle tibiae very feebly arcuate, the posterior .straight ;
last ventral segment (103) longer than in the male, the apex with a scarcely per-
ceptible truncation, usually with a slightly elevated serrulate ridge in front of
the apex, last dorsal coarsely sparsely punctate, a small triangular emargination
at apex.

92 GEO. H. HORN, M. D.

In sculpture this species occupies an exactly intermediate position
between ludificaia and trinervia, the sexual characters of the male
apart from the last ventral are also intermediate. As already re-
marked, a strict regard for the sexual peculiarities is necessary to
enable the species to be correctly separated.

Four female specimens in my cabinet from Nevada are entirely
green beneath.

Occurs in Colorado and Nevada.

21. C. oaurina n. sp. — Form nearly as in femorata, piceous, surface dark
bronze, the punctured spaces usually cupreous, rarely greenish, body beneath
feneous, sometimes slightly greenish along the middle ; antennje more slender to
tip, greenish % or cupreous 9 , third joint as long as the next two ; front %
rather flat, greenish, densely punctate and with two callosities, or in 9 more
convex, more coarsely punctured and cupreous; clypeus (106 > very broadly tri-
angularly emarginate at middle, arcuate each side ; thorax nearly twice as wide
as long, sides at middle nearly jjarallel or slightly sinuate, at apex and base nar-
rowed ; disc feebly convex, median line broadly depressed and densely punctured,
limited each side by an irregular but rather broad smoother space, usually two
callosities toward the side, the surface otherwise densely and very coarsely punc-
tured ; elytra a little wider than the thorax, parallel, narrowed at apical third,
the margin serrulate, the apices obtuse ; disc subdepressed, the first costa distinct,
sometimes nearly entire, the second and third more or less interrupted, the fourth
existing as a finely elevated line, the intervals with densely punctured spaces of
irregular shape, and broad smoother spaces with reticulating lines near the sides,
basal fovea moderate ; body beneath sparsely punctate ; prosternum truncate in
front; anterior femur with rather obtuse tooth, very feebly serrulate; last ven-
tral segment with margin serrate. Length .34 -.44 inch; 8.5-11 mm. (Fig. 10.5.)

Male. — Prosternum densely punctured, sparsely pubescent; anterior tibia (109)
arcuate, the inner edge with a rather deep notch one-third from the apex, and
an obtuse dilatation narrowing again at the tip ; middle til)ia arcuate, rather ab-
ruptly dilated at apex, posterior tibia straight; last ventral (107) with deep,
semi-circular emargination and vaguely depressed along the middle ; last dorsal
sparsely punctate, triangularly emarginate at tip.

Female.- — Prosternum coarsely .sparsely punctate ; anterior tibia feebly arcuate,
not dilated at tip, middle and posterior straight; last ventral (108) with a feeble
emargination limited in front by a distinctly elevated transverse carina; last
dorsal coarsely punctate, with a very feeble notch at middle.

This is one of the species separated from the series formerly
thought to be varieties of trinervia. On comparison the present
species differs from trinervia and carinipennis in having the cost?e
much less distinct and more interrupted, and the densely punctured
spaces less numerous and the smooth spaces consequently much larger.
The true differences must, however, be looked for in the sexual char-
acters as figured.

Occurs in Colorado, Nevada and Oregon.

. 22. C califoriiiea Lee. — Form very like trinerria, but rather more de-
pressed and broader ; color dark cupreo-seneons, sometimes slightly greenish,
beneath rather brassy, sometimes slightly greenish ; antennae greenish % or
cupreous 9) gradually more slender to the tip, the third joint as long as the
next two ; front flat, greenish, more densely punctured and slightly i)ubescent % ,
slightly convex, seneous, more coarsely punctured f ^md with two indistinct
callosities in both sexes; clypeus (111) with a broadly oval emargination at mid-
dle, arcuate each side; thorax twice as wide as long, narrowed at apex and base,
the sides at middle often slightly sinuate ; disc moderately convex, a median,
broad, densely punctured sulcus limited each side by a broad elevated space
which is smooth in front and very coarsely punctate posteriorly, two oblique
callosities near the side, the surface otherwise densely and coarsely punctate :
elytra a little wider than the thorax, parallel, narrowed at ajiical third, the mar-
gin feebly serrulate, the apices obtuse ; disc with the first costa entire, hut less
elevated and liroader near the base, the other co.sta interrupted, the third quite
oblique, often joining the second at middle, the intervals between the costse with
alternating smooth and punctured spaces, the punctuation dense or sparse in
places, the basal depressions rather feeble ; body beneath coarsely but sparsely
punctate, the ventral segments with distinct lateral callosities; prosternum (99)
with a short, broad lobe in front ; anterior femur with a moderate tooth, serru-
late externally ; last ventral segment serrulate at the sides and with a feeble
submarginal elevation. Length .40 -.76 inch; 10 -19 mm. (Fig. 110. J

Male. — Prosternum densely punctate, spar.sely pubescent ; anterior tibia (114)
flexed at apex and base and with a nearly semi-circular dilatation at apical
fourth ; middle tibia slightly arcuate and gradually broader at apical third, the
posterior straight; last ventral .segment (112) deeply semi-circularly emarginate,
the last dorsal coarsely punctate, acutely notched at middle.

Female. — Prosternum more convex, more coarsely and not densely punctured ;
anterior tibia feebly arcuate, the middle and posterior straight; last ventral (113)
subtruncate at apex, the angles acute, last dorsal crihrately punctured with a
slight notch at tip.

This species seems to vary more in size than in any of those with
the sculjiture of the style of trinervia, and its smaller forms greatly
resemble some of those, especially caurina, and for its separation the
presence of the prosternal lobe, although feeble, and the sexual char-
acters Avill suffice.

With this species I have united vulcanica Lee. as a smaller form.

Occurs in the northern part of California and in Nevada.

tured ; elytra a little wider than the thorax, gradually narrowed fi-om the mid-
dle to the apex, the sides feebly serrate, the apices obtuse; disc subdepressed,
the first costa sharply elevated from the apex to the middle, extending to the

between the ends of the second costa, the basal fovea shallow, the surface mod-
erately coarsely and rather irregularly punctured ; body beneath very shining,
the punctures moderately coarse and not closely placed, ventral segments with-
out distinct lateral callosities ; prosteruum distinctly lobed in front, the lobe

apex ; middle tibia arcuate and gradually broader near the tip, the posterior very
slightly arcuate; last ventral segment (117) semi-circularly emarginate; last

It is remarkable that a species from a locality from which this
comes should have remained so long unseparated, it having doubtless
been mixed with denUpes as a smoother and smaller variety. To the
acute observation of Mr. Fred. Blanchard we are indebted for its
recognition, and by him ray attention was first directed to the varia-
tion of the form of the prosternum in this genus. I take great
pleasure in making his name the specific appellation of this insect as
an evidence of my appreciation of his cai-eful study as well as of
his many kindnesses.

Occurs in Massachusetts (Tyngsboro'), District of Columbia and
Lake Superior region.

Valley could not possibly have had that habit.

Occurs in California, Nevada, Utah and Colorado.

This is a small and inconspicuous species quite constant in its color,
but variable in the distinctness of its markings as the costse may
almost entirely disappear and the foveae become very vague. The
basal depression of the elytra usually remains quite distinct.

Occurs from Massachusetts to Wisconsin and North Carolina ;
does not seem to be rare.

differing in its style of ornamentation as well as by the sexual char-
acters.

Occurs in western Nevada, and at Calaveras, Cal.

Group V.

The following species form a small and apparently natural group
characterized by a subcylindrical, parallel form, with the elytra very
little wider than the thorax. The upper surface is usually slightly
pubescent with grayish hair, but this with careless handling is apt to
be lost. The thorax is convex, and while but one exhibits a faint
trace of median depression several have callosities. The punctuation
is dense and rather coarse. In some respects this group seems to
connect the first and second groups, but the species appear, on the
whole, to be degraded forms of the series with the last ventral seg-
ment serrate, and to represent, or at least parallel the group placed
at the end of the other series.

The prosternum is lobed in all the species, the lobe short and in-
distinct in the bronze species, very prominent in the blue species.

The following table will assist in the determination of the species :

Anterior femur distinctly toothed.
Color dark bronze or greenish.
Thorax with distinct callosities.

El>i:ral costa; distinct; sides of thorax regularly arcuate 30. deleta.

Elytra! costse replaced by smooth lines ; sides of thorax narrowed at ajiex

and base .31. desorta.

Thorax without callosities, the punctuation coarse, but not crowded ; sides

regularly arcuate ; costse of elytra distinct 32. lixa.

Color bright blue, green or violaceous.

Thorax with faint median depression (in the larger specimens), sides nar-
rowed at base; elytral sculpture very feeble 33. eyaiiella.

Anterior femur without tooth.
Color blue-green.

Surface densely punctulate ; sides of thorax regularly arcuate ; apex of ab-
domen exposed 34. Iiiiiiiilis.

Of the five species of this group three occur in California (two
Southern, one from the North), the other two are from Arizona.

30. C. deleta Lee— Moderately elongate, subcylindrical, dark bronze, some-
times brownish or greenish, sparsely pubescent ; antennse rather short, gradually

bronze in 9 ; head slightly convex and \vith two frontal tubercles in both sexes,
green and more densely punctate % , bronze and more coarsely punctate 9 !
clypeus (151) with an oval emargination at middle ; thorax twice as wide as long,
sides regularly arcuate, disc convex, very coarsely and closely punctate and with
four callosities transversely placed (the outer indistinct) and a median posterior
smooth line ; elytra scarcely wider than the thorax, parallel, narrowed at apical
third, the margin very finely serrulate, the apices obtuse ; disc convex, the first
costa distinctly elevated from apex to middle, the outer costfe indistinct and in-
terrupted ; basal fovea distinct, the discal fovese scarcely visible ; body beneath

segments with indistinct lateral callosities ; last ventral segment with serrulate
border ; prosternum with a small lobe in front ; anterior femur with a very acute
tooth, serrulate on its outer edge. Length .28- .36 inch ; 7-9 mm. (Fig. 150.)

Male. — Prosternum coarsely and closely punctate, sparsely pubescent ; anterior
tibia [ 154) feebly arcuate, stouter toward the tip, with a slight and short dilata-
tion near the apex ; middle tibia slightly arcuate, thickened at the extreme apex ;
posterior tibia straight ; last ventral (152) nearly semi-circularly emarginate.

Female. — Prosternum coarsely not closely punctate ; anterior tibia slightly ar-
cuate, gradually stouter to the tip ; middle and posterior tibise straight ; last ven-
tral segment (153) oval and entire at apex, a slight sinuation each side limited by
the last serration of the margin ; last dorsal coarsely and densely punctured and
entire.

In one specimen before me the body beneath is entirely green. As
a rule the punctures of the under side, particularly of the abdomen,
are much coarser and more distinct than in deserta. While there is
some little variation in scul])ture, the first or subsutural costa remains
distinct in its posterior half

Occurs in California (Owen's Valley and northward) and Wash-
ington Territory.

not densely punctured, an indistinct chevron above, sparsely pubescent and
greenish % ; clypeus (156) very broadly but not deeply emarginate; thorax
nearly twice as wide as long, sides rounded at apex and base, disc convex, veiy
coarsely and closely punctured with four callosities arranged in a transverse row
in front of the middle and a smooth median line jiosteriorly ; elytra scarcely
wider than the thorax, parallel, narrower at apical third, the margin very feebly
.serrulate, the apices obtuse, disc convex, the costie replaced by smoother lines,
basal fovea deep, two indistinct discal fovese, one on the second smooth line one-
third from base, the second one-third from apex between the first and second
smooth lines, surface rather coarsely and closely subgranulately punctured ; body
beneath more shining than above, very coarsely and closely punctate, the punc-
tures of the abdomen much finer and submuricate ; margin of last ventral seg-
ment distinctly serrulate ; prosternum with a very short lobe in front ; anterior
femur with a small acute tooth, serrulate on its distal edge. Length .35 inch ;

NORTH AMERICAN COLEOPTERA. 101

Male. — Prosternura deusely punctate, sparsely pubescent ; anterior tibia (158)
slightly arcuate, with a small semi-circular dilatation before the apex ; middle
and posterior tibise straight; last ventral segment (1.57) broadly arcuately trun-
cate ; last dorsal sparsely punctate, entire.

Of this species I have seeu but three males. It resembles very
closely and might readily be mistaken for deleta, which has, however,
the first costa at least elevated neai- the apex. In deserta the clypeus
is rather more broadly emarginate and the anterior tibia of the male
otherwise formed.

Occurs in the Mojave Desert of California, also near San Diego.

32. C lixa n. sp. — Form subcylindrical, moderately convex, dark bronze,
moderately shining, sparsely pubescent ; antennte dark bronze, gradually more
slender to the tip, the third joint but little longer than the second or fourth;
front convex, coarsely and moderately closely punctured in both sexes and
slightly pubescent; clypeus (160) broadly triangularly emarginate at middle,
rounded on each side ; twice as wide as long, base and apex equal, the sides regu-
larly arcuate ; disc convex, coarsely, deeply and rather closely punctate, more
densely at the sides, often with a median smooth space posteriorly, but without
distinct callosities ; elytra scarcely wider than the thorax, parallel, narrowed at
apical third, the margins finely serrulate, the apices obtuse ; disc convex, the first
costa distinctly elevated from the apex to middle or even more, and continued
by a smooth line, the second and third indicated by smooth lines, basal fovea dis-
tinct, a faint, more densely punctured fovea one-third from apes external to the'
second co.sta, another in front of middle interrupting the second costa, surface
otherwise relatively coarsely and rather closely punctate ; body beneath more
shining than above, the punctuation less coarse and moderately close along the
side of the body and ventral segments, these with a feeble lateral umbone, the
last segment with serrulate margin ; anterior femur with a small, rather acute
tooth, serrulate on its outer edge ; jn'osternum scarcely lobed in front. Length
.16 - .28 inch ; 4-7 mm. (Fig. 1.59.)

Male. — Prosternum coarsely and moderately closely punctured, scarcely punc-
tured near the anterior margin: anterior tibia (163) .slightly arcuate and grad-
ually thicker to tip and with a very faint dilatation at apex ; middle tibia very
slightly arcuate, the posterior straight; last ventral segment (161) nearly semi-
circularly emarginate, last dorsal coarsely sparsely punctate, slightly emarginate
at apex.

Female. — Prosternum more coarsely and si)arsely punctate, a median smooth
space posteriorly; tibiae nearly straight; last ventral (162) longer than in the
male, the apex truncate, with distinct but not prominent angles; last dorsal
coarsely, sparsely punctate, apex entire.

This species might be mistaken for a small form of deleta. It is,
however, more cylindrical, the punctuation relatively coarser, and
the thorax without callosities. The male sexual characters are not
different, but the last ventral of the females is distinctly so.

Occurs in Texas and Arizona, taken rather abundantly by Morri-
son in the latter reg-ion.

33. C cyaiiella n. sp. — Form subcyliudrif-al, very slightly depressed, color
bright blue or green, becoming violaceous on the elytra rarely, surface slightly
pubescent, beneath greenish blue ; antennse greenish % or piceous 9 > ^ little
more slender to the tip, the third joint as long as the next two; front slightly
convex in both sexes, more densely punctured in the male and vrith two small
callosities, more coarsely punctured in the female, the callosities almost obliter-
ated ; clypeus (165) with a small oval emargination at middle, arcuate each side ;
thorax twice as wide as long, or even a little wider, arcuately narrowed in front,
obliquely at base, disc convex, with a vague median depression in the larger
specimens, which is wanting in the smaller ones, a distinct rounded fovea near
the side, surface coarsely, deeply and moderately densely punctured, and in the
largest specimens transversely confluent near the sides; elytra a little wider
than the thorax, parallel, apical third arcuately narrowed, the margin scarcely
serrulate, the apices obtuse, disc feebly convex, the costse faintly indicated only
in the larger specimens and then by smoother lines, the basal fovea not deep, the
surface somewhat irregular, and occasionally with faint traces, the first quite
small, one-third from apex and near the fourth costa, the second larger on the
second costa in front of middle, the surface rather coarsely and not densely
punctured, except near the base ; body beneath rather sparsely punctate, the
ventral segments without lateral callosities, the last segment with serrulate
margin ; prosternum very distinctly lobed in front ; anterior femur with a mod-
erately large tooth with but few serrations externally. Length .20 - .42 inch ;
5-10.5 mm. (Fig. 164.)

Jf«?e.— Pi-osternum flat, very densely punctate, sparsely pubescent; anterior
tibia (168) feebly arcuate, a shoi't and narrow dilatation at tip; middle tibia,
slightly arcuate, a little thicker at tip, posterior tibia straight ; last ventral seg-
ment (166) with a shallow semi-circular emargination ; last dorsal coarsely punc-
tate and with a rather broad, triangular notch at tip.

Female. — Prosternum flat, more coarsely punctate than in the male ; anterior
tibia feebly arcuate, the middle and posterior straight ; last ventral (167 1 a little
longer than in the male, a barely perceptible notch at apex ; last dorsal coarsely
punctate and with a slight notch at tip.

The subcylindrical form, blue color and the well lobed prosternum
make this species an easily recognized one. The larger specimens do
not vary greatly from deleta in the elytral sculpture, except that it is
more obliterated, while this is even lost as the specimens become
smaller, so that the elytra have only the punctuation remaining.
The color varies from green to blue and violet, as is usual in blue
species. The largest specimen I have seen is in the collection of
Mr. H. Edwards, and is that from which the figure was prepared.

Occurs in the mountain regions of northern California near Yreka
and Mt. Shasta.

34. C hnmilis n. sp.— Form subcylindrical, parallel, moderately robust,
color bluish green, variable in the direction of the light, subopaque, beneath
blue-black, with white pubescence, femora bright feneous ; antennae rather stout,

jiunctate ; elytra very little wider than the thorax, parallel, arcuately narrowed
at apical third, the margin serrulate, the apices very obtuse, exposing the tip of
the abdomen ; disc moderately convex and even, the basal fovea very faint, sur-
face very densely and equally punctate, the punctures a little finer than on the
thorax and with a tendency to form oblique strigse near the sides ; body beneath
moderately, densely punctate, and clothed with short white recumbent pubes-
cence, sides of abdomen more densely punctulate and pubescent, the margins of
the segments on each side sutures two, three and four smooth ; last ventral seg-
ment with serrulate margin ; prosternum rather strongly lobed in front ; anterior
femur without trace of tooth. Length .22 inch ; 5.5 mm. (Fig. 169.)

3Ia}e. — Unknown.

Female. — Prosternum flat, closely punctate ; the tibise all straight ; last ventral
segment (171) sinuately truncate ; last dorsal segment punctate, the tip emar-
giuate.

This species is a diminutive in form of atrifasciata, and could
have been placed next to it if the last ventral segment had not ser-
rulate margins. I place it, however, among the subcylindrical spe-
cies, admitting at the same time that it shows a marked relationship
with debilis in the sculpture and pubescence of the under surface as
well as with atrifasciata in its general form. It is remarkalile in the
absence of femoral tooth, and while the specimen is a female it is not
probable that the male is otherwise, as I have not observed any dif-
ferences in all the other species in the form or size of the femoral
tooth between the sexes.

One specimen, Arizona.

Group VI.

The species of the small grcjup here separated are of medium or
rather large size. They agree in having the thorax widest anteriorly,
the sides from the anterior third narrowed to base ; the prosternum
is not lobed in front, and in both sexes is nearly smooth along the
middle ; the last ventral segment has the margin devoid of serrula-
tions, although in several the edge is interrupted ; in the male the
apex is usually very deeply, almost quadrangularly emarginate. The
apices of the elytra are rather acute and more or less prolonged in a
spine.

The following table will assist in recognizing the species :

Thorax not sulcate at middle, or with a feeble trace of a depression.

by the anterior fovea and not joining the fourth near the apex.

36. geiiiinata.

Elytra with two indistinct fovefe ; the second costa continuous through the
anterior fovea and at apex joining the fourth costa 37. Jlerkelii.

Elytra with two discal cupreous fovese ; second costa interrupted by the
anterior fovea and not joining the fourth at apex; disc of thorax with

vague median depression 38. aciitipeiiiiis.

Thorax with a well marked median sulcus ; elytral costs© interru]ited ; last ven-
tral segment with slightly interrupted margin 39. libonoti.

The s])ecies of this group, which are all from the extreme south-
western regions of our country, recall in a striking manner the spe-
cies of the first group by their size, outline and many points in their
sexual characters.

35. C. serea Chev. — Form rather elongate, piceous, with feeble bronze sur-
face lustre, beneath more brassy and shining, sometimes slightly cupreous; an-
tennse bronzed % or piceous 9 , gradually more slender to the tip, the third
joint a little longer than the next three ; front nearly flat, seneous, densely punc-
tured and finely pubescent % , more coarsely and irregularly punctured and with
irregular smooth spaces 9 ! clypeus (174) deeply triangularly emarginate at mid-
dle, arcuate each side ; thorax nearly twice as wide as long, obliquely naiTowed
in front, the sides straight, nearly parallel or slightly convergent to base, the hind
angles distinct ; disc moderately convex, slightly depressed at middle, sometimes
a vague depression at base opposite the middle of each elytron, and with irregular
callo.sities near the sides in front ; surface finely sparsely punctured at middle
third, with a smooth median line, near the sides more coarsely and densely punc-
tured ; elytra a little wider than the thorax, gradually narrowed almost from

first usually well defined from apex to middle, the others finer, more or less in-
terrupted, connected by intervening smooth spaces, one moderately large, densely
punctured discal fovea ou the second carina one-third from base, usually sur-
rounded by a smooth elevated border, intervals between the carinae rather finely,
not very densely punctured, the punctuation finer and sparser in the scutellar
region ; body beneath nearly smooth along the median line, except ou the abdo-
men, whfere the punctures are coarse and sparse, sides of body more densely and
finely punctured and slightly pubescent ; ventral segments with feeble callosities
and with the hind angles slightly prominent ; last ventral segment with the mar-
gin not serrate, but with an interruption at the posterior third ; prosternum
slightly arcuate in front, but not truly lobed ; anterior femur with a moderately
large tooth not serrate. Length .68 - .86 inch ; 17 - 22 mm. ( Fig. 173. )

ilfaie.— Prosternum with very few fine punctures at middle, a line of piliferous
hairs along the sides and very coarse punctures at the sides in front ; anterior
tibia (177) feebly arcuate, slightly dilated at tip, a slight tooth at the beginning
of the dilatation, above which is a distinct notch ; middle tibia slightly arcuate,
the posterior straight; last ventral (175) with a short, flat carina at middle in
front, the apex vei-y deeply emarginate, the angles prominent and sinuately
truncate ; last dorsal segment coarsely punctured and entire.

i^ema^e.— Prosteruum as iu the male; tibise are all nearly straight ; last ven-
tral segment (174) sinuately truncate with prominent angles, a broad obtuse
carina extending from base nearly to apex.

This is one of the h\rgest species in our fauna and may be at once
known by the interrupted margin of the last ventral segment, the
edge not being serrate. My first specimen was given me by Dr. C.
A. Dohrn, of 8tettin, since which others have been collected by
Morrison in Arizona. On comparison with the Saunders collection
now in the British Museum it bore the name cosUfrom Chev. The
facies of the species is quite unlike our others, and it would not have
been introduced in the pi-esent essay except from the specimens col-
lected by Morrison.

Being somewhat in doubt, however, regarding the status of costi-
from I communicated with my friend Salle, who, with his usual
kindness, sends me a specimen of C. crrea Chev. {mexicana Dej.)
with the following remarks : " The C. costifrons Chev. is very near
to it (cerea), but the elytral impressions are more round and brilliant
golden." From my own comparisons I am satisfied that the chai'ac-
ters referred to by Salle are purely varietal, and that costifrons can-
not be considered a distinct species.

Occurs in Arizona, extending as far south as Oaxaca, Mexico.

tibia very slightly arcuate, the middle and posterior straight ; last ventral seg-
ment (181) longer than in the male, sides slightly sinuate near the tip, the apex
sinuously truncate, the angles acute, the median line rather strongly carinate.

This species is one of the hxrgest iii our faunii and is consjiicuous
by the purplish color of its surface, the well marked golden spots
and the very regular and even surface scul])ture.

Hale. — Prosternum slightly convex at middle, with a few coarse punctures, the
anterior angles more densely punctured and slightly pubescent ; anterior tibise
(187) slightly arcuate, not dilated at tip, the inner edge multidenticnlate, the
middle tibia similar; posterior tibia straight; last ventral segment (185) broadly

robust and with fewer and less distinct elytral spots, the surface color
being also ditierent. From the latter it differs in its stouter and
more robust form and the absence of median depression of the thorax.

For specimens I am indebted to the kindness of Mr. Aug. Merkel,
of New York, to whom I take great pleasure in dedicating it.

Occurs in Texas and Arizona.

In both sexes the last ventral segment has near the margin a feebly
elevated serrate ridge. The species has the appearance of a gigantic
sexsignata. This species, Merkelli and geymnata, form a very natural
group with the costse well defined ; they differ in the number, posi-
tion and distinctness of the fovea?.

Occurs iu Texas, Arizona and Mexico.

remarkable in having practically no difference between the sexes in
the prosternum and in the form of the tibiae.

Grou]) VII.
The species of this group are all of small size, excepting impressa
and chalcophoroldes, and have in great part a feeble development of
elytral sculpture. They agree in having the last ventral segment
with entire margin and the apices of the elyti'a obtuse.

This species occurs at Surinam, and is recorded from Santo Do-
mingo. While mentioned by Chevrolat in his " Coleopteres de
Cuba," (Ann. Fr. 1867, p. 586) it is not credited to that island. In
the " Catalogus G. and H.," the species appears as a Colobogaster,
while in the " Catalogus Buprestidarum," Saunders, 1871, the specific
name tranquebarica is adopted.

The specimens before me were collected at Key West, Fla., by
Morrison, and kindly given me by Mr. G. W. J. Angell, of New
York.

Female. — Anterior tihia (206) feebly arcuate, the middle and posterior straight ;
last ventral .segment (205) sinuately truncate, the angles distinct, the surface
smooth at middle, a distinctly elevated submarginal serrulate ridge.

The large size and robust form of this species are rather striking
in its association with those forms in which the apices of the elytra
are not spiniform. The sculpture is also peculiar and with the sui--
tace color resembles more closely our species of Chalcophora near
v{rgini€n.'iii<.

One specimen from Arizona given me by Mr. F. G. Schaupp with-

Of all the species without special supei-ficial characters this one is
probably the easiest to recognize by its structural characters. There
is but little variation, except in color. The sexual characters as

112 (4E0. H. HORN, M. D.

given by Dr. LeConte are, unfortunately, reversed, the dilatation of
the anterior tibiae indicating the male not having been observed.

ventral segment with entire margin; anterior femur with a moderate tooth,
sinuate and serrate on its distal edge ; prosternum not lobed in front. Length
.26 -.50 inch; 6.5-12.5 mm. (Fig. 212.)

Jlfa^e. —Prosternum flat, densely punctured, sparsely piibescent; anterior tibia
(216) arcuate, not dilated at tip, serrulate within ; middle tibia less arcuate and
less serrulate ; posterior tibia straight ; last ventral (214) finely carinate at mid-
dle, semi-circularly emarginate at tip, the angles acute ; last dorsal coarsely punc-
tate, apex entire.

Female. — Prosternum a little more coarsely punctured ; anterior tibia feebly
arcuate, the middle and posterior straight ; last ventral segment (215) strongly
carinate at middle, the apex truncate, the angles slightly prominent.

This species represents in this series /e^n orate in the other, many of
its characters of form, sculpture and sexual modifications are similar,
as will be seen on comparison.

Occurs from New York to Virginia, westward to Nebraska and
Indian Territory.

44. C. aziirea Lee. — Form rather broad, subdepressed, color variable from
blue to greenish blue, violet or cupreous, beneath blue, the sides of the abdomen
sometimes cupreous; antennse greenish % or bronze ?, gradually more slender
to the tip, the third joint nearly as long as the next three ; front slightly convex,
coarsely and rather closely punctured; clypeus (218) very broadly not deeply,
triangularly emarginate at middle, on each side slightly arcuate ; thorax nearly

twice as wide as long, widest slightly behind the middle, sides sit apex and base
narrowing, at middle slightly sinuate : disc moderately convex, without well
marked depressions, except the usual post-apical, surface coarsely punctate, the
punctures rather close at middle and sometimes transversely confluent, at sides
much more dense ; elytra wider than the thorax, gradually wider to two-thirds,
then arcuately narrowing to apex, the margins serrate, the apices obtuse ; disc
feebly convex, a faint trace of the first costa and barely pei-ceptible smooth lines
indicating the others, the basal fovea small but distinct, two discal fovese, one in
front of middle, the other one-third from the apex, the foveae often brighter blue
or green; surface coarsely punctate, not closely in apical half, more densely near
the base ; body beneath more shining than above, usually blue, rarely green,
these latter with the sides bright cupreous, as in sexsignata, the surface rather
sparsely punctate ; prosternum scarcely perceptibly lobed in front ; anterior femur
with a rather broad tooth, serrulate on its distal edge ; last ventral segment with
entire margin. Length .24- .31 inch ; 6- 8 mm. (Fig. 217.)

Male. — Prosternum densely, coarsely punctured over its entire surface ; ante-
rior tibia (221) arcuate, thicker to tip, but not dilated at apex ; middle tibia
slightly arcuate, the posterior straight ; last ventral segment (219) deeply, semi-
circularly emarginate, the angles acute, a slight carina at middle posteriorly.

i^emrt/c — Prosternum a little less densely punctured ; anterior and middle tibiae
slightly arcuate, the posterior straight; last ventral (220) truncate, with the
angles acute and prominent, slightly carinate, at middle posteriorly.

This species from its variable color might be confounded with
Hai-risii or .^cihila, but the structure of the antennae will distinguish
it from the first, and of the thorax from the second. In one speci-
men I have seen the suture of the elytra is greenish metallic.

Occurs in New York, Illinois, District of Columbia, Georgia and
Texas.

45. €\ teueola Lee — Form rather broad, subdepressed, nearly as in jjusiUa,
dark bronze, subopaque ; front slightly convex in both sexes, coarsely punctured,
a little more closely in the male, the female with two faint chevrons, dark
bronze 9 > slightly greenish % ; antenufe rather broad, gradually more slender to
the tip, the third joint not as long as the next two ; clypeus (223) acutely emar-
ginate at middle arcuate each side, closely resembling femorntn ; thorax a little
more than twice as wide as long, narrowed in front, sinuate at the middle of the
sides, incurved posteriorly ; disc feebly convex, a vague median sulcus, a deeper
depression near the sides ; surface moderately and coarsely punctate, slightly
transversely confluent in the female ; elytra scarcelj^ wider than the thorax, par-
allel, narrowed at apical third, the margin feebly serrulate, the apices obtuse ;
disc subdepressed, basal fovea moderate, a longer humeral depression, first co.sta
slightly elevated from apex one-third to base and continued slightly by a smooth
line, the other costa faintly indicated by short lines ; surface moderately, densely,
equally punctured without distinct fovese ; body beneath much more shining than
above, the punctures of the abdomen rather sparse and indistinct ; last ventral
segment with entire margin ; prosternum not lobed in front ; anterior femur
with a moderate tooth not serrulate on its margin. Length .27 inch ; 7 mm.
(Fig. 222.)

3Iale. — Prosternum densely, coarsely punctured and slightly pubescent between
the coxae, more sparsely punctured in front ; anterior tibiae (226) arcuate and
with a dilatation at apical third ; middle tibiae straight, slightly thickened at tip,
posterior tibia straight; last ventral segment (224) with a shallow, semi-circular
emargination, the last dorsal sparsely punctate, vaguely emarginate at tip.

Female. — Prosternum coarsely, sparsely punctate; anterior tibia slightly arcu-
ate, the middle and posterior straight ; last ventral segment (225) very slightly
notched at tip, longer than in the male, the sides slightly sinuate ; last dorsal
sparsely punctate, entire.

This species is very inconspicuous and might readily be mistaken
for p mi /la. In the typical specimens the elytra show no traces of
more densely punctured foveas, although there are slight depressions
where they should be, but in some specimens I have examined the
foveie are nearly as plain as in puslMa, thereby increasing the resem-
blance, at the same time the elytral punctuation is coarser.
Occurs in Kansas, Nebraska, Nevada, Texas and Arizona.

46. C clirysoela Illig. — Form moderately broad, not depressed, color pur-
plish black, or faintly cupreous ; elytra with golden to greenish spots, usually
four on each side, the posterior two often transversely confluent ; body beneath
dark bronze ; antennae gradually more slender to tip, cupreous in both sexes, the
third joint a little longer than the next two; front slightly convex, coarsely
punctured, an arcuate carina above joining the occipital carina, greenish % or
bronze 9 ! clypeus (228) triangularly emarginate at middle, arcuate each side;
thorax twice as wide as long, anterior angles obliquely truncate, the sides slightly
sinuous ; disc moderately convex, without depressions, punctuation coarse,
sparser at middle, dense near the sides; elytra wider than the thorax, slightly
broader behind the middle, arcuately narrowing at apical third, the margin ser-
rulate, the apices obtuse ; disc moderately convex, without trace of costae, basal
fovea moderately deep, golden or green, this color often reaching the humeri, a
distinctly impressed fovea near the middle of each elytron and a spot opposite on
the lateral margin, these often united, one-third from apex two spots, these often
transverely confluent ; surface coarsely but not closely punctate ; body beneath
with very large punctures, the ventral segments without callosities, the margin
of the last ventral entire ; prosternum faintly lobed in front ; anterior femur with
a moderate, acute tooth, not serrulate. Length .28 - .32 inch ; 7 - 8 mm. ( Fig. 227. )

ilnle. — Prosternum very coarsely punctate, a uarrow elevated median line ; an-
terior tibia (231) arcuate, a very slight dilatation near the tip; middle tibia
slightly arcuate, the posterior straight; last ventral segment (229) with a broad,
but shallow, arcuate emargination, the angles distinct ; last dorsal coarsely punc-
tured, the apex entire.

Female. — Prosternum as in the male ; anterior and middle tibiae slightly arcuate,
posterior straight ; last ventral (230) sinuately truncate, the angles acute, a sub-
apical serrulate ridge ; last dorsal as in the male.

This species and scitula are closely related, more so in description
than in facies. The present species has a broader thorax, and is in
fact broader generally, the punctuation is less coarse and the elytral
spots of difll^rent appearance and form.

NORTH AMERICAN COLEOPTERA. 115

This species seems strictly southern in its distribution, occurring
from Virginia to Florida and Texas.

47. C seitula Gory. — Form rather elongate, moderately convex, color deep
violet, or dark cupreous, the thorax often more decidedly blue, each elytron with
three more brilliant spots, blue or green, and of variable distinctness and ex-
tent; antennse gradually more slender to tip, piceous, three basal joints greenish
% or cupreous 9- third joint nearly as long as the next three; front slightly
convex, green % , violaceous 9 1 coarsely and deeply punctured, an arcuate line,
the concavity upward, above which is a slight depression in both sexes ; clypeus
(23.3) with a small triangular emargination at middle, subtruncate each side;
thorax one and a half times as wide as long, the sides straight, very slightly con-
vergent posteriorly, rounded near the front angles, the hind angles distinct and
sometimes slightly everted; disc convex, without depressions or callosities, sur-
face coarsely jiunctured, sparsely at middle, more densely near the sides, some-
times slightly transversely strigose ; elytra wider than the thorax, humeri
rounded, sides slightly wider behind the middle, arcuately narrowed at apical
third, the margin finely serrate, the apices obtuse ; disc convex, the punctuation
coarse, deep, but not dense, there is no trace of costpe and the fovese are scarcely
impressed, the basal even rather shallow, the colored spots are placed in the usual
position of the fovefe of the other species ; body beneath violet-blue, punctuation
coarse, but sparse, the ventral segments without umbones, their angles not promi-
nent ; presternum distinctly lobed in front ; anterior femur with rather strong
tooth, obsoletely serrate or simple ; last ventral with entire margin. Length
.22 - .28 inch ; 5.5 - 7 mm. ( Fig. 232. )

Male. — Presternum flat, densely punctured, not pubescent; anterior tibia (2.36)
arcuate, a slight dilatation near the tip ; middle tibia feebly arcuate, the posterior
straight ; last ventral (234) with a very shallow, broad emargination ; last dorsal
very coarsely punctured, entire at apex.

Female. — Prosternum as in the male ; anterior tibia slightly arcuate, the middle
and posterior straight; last ventral (235) sinuately truncate, the angles promi-
nent ; last dorsal coarsely punctured, entire.

This species appears in the monograph of Laporte and Gory as
vltramarina Say. Dr. LeConte recognizing the erroneous determi-
nation pro])osed the name azurea for it (Proc. Acad. 1857, p. 8), and
in his " Revision of the Buprestidse" (Trans. Am. Philos. Soc. xi,
1859, p. 288) the name concinnula Lee. is substituted and azurea used
for another species. Later, in the " Check List," Crotch used the
name chlorocepha/a. During his visit to Europe Dr. LeConte exam-
ined many of the types of Gory and Laporte in the possession of
Count Mniszech, and obtained a specimen of scitula, which proves to
be merely a more brilliantly colored variety of uUramarina % Gr.
and L., and concinnufa Lee. I have for these reasons adopted the
name scitula as the prior name.

The more brightly colored specimens resemble both azurea and
somewhat Harrml, but the form of the thorax is quite characteristic,

116 GEO. H. HORN, M. D.

and the strong rather distant j)unetuation of the elytra is ahnost
peculiar to the present species.

Occurs in the Middle States region, New Jersey, Pennsylvania,
Ohio and District of Columbia.

Group VIII.

Three species are separated below as a group, the essential chai'ac-
ters being : — last ventral segment with the margin entire, not serru-
late ; elytra with the apices separately rounded, the disc without
trace of either costa or fovea.

The following table will distinguish the species :

Species of rather large size, robust, apex of abdomen exposed beyond the elytra,
punctuation of surface rather coarse, elytra with three interrupted purple-
black fascife.

Sides of thorax regularly arcuate 48. atrifa^ciata.

Sides of thorax oblique in front, arcuate posteriorly 49. l^lltei.

■ Species rather small and slender, the punctuation sparse and fine ; elytra cov-
ering the abdomen, color bright green, without fascife.
Sides of thorax very feebly arcuate 50. prasina.

The male is known of the first species only, in it the antennte are
bipectinate, the terminal joint itself being bifurcate. In the female
the lower edge of the antennae is broad, so that in section the anten-
nal joints are an equilateral triangle. In the other two species, of
Avhich only females are known ; the antennae present the usual flat-
tened form, and it is probable that those of the male do not differ in
structure from the normal type.

The three species are western, atrifamcda occurring in New Mexico
and Arizona, JJlkel in Texas and prasina in the north of California.

48. C. atrifasciata Lee. — Form robust, slightly depressed, cylindrical,
bright green or blue, varying to golden or cupreous ; elytra with three inter-
rupted fasciae of black or purple color ; antennae variable in form in the two
sexes, dark bronze, third joint very nearly as long as the next three ; front con-
vex, not differing in color in the two sexes, coarsely and deeply punctured and
with an arcuate, transverse, elevated line above, beneath which is a zigzag line
in form of W ; clypeus (239) very broadly not deeply emarginate ; thorax more
than twice as wide as long, slightly broader at base than apex, the sides regularly
arcuate ; disc convex, a smoother median line posteriorly ; punctures near the
middle very coarse and deep, at the sides more dense ; elytra scarcely wider thaik
the thorax, parallel, narrowed at apical third, the apices separately rounded and
not covei'ing entirely the abdomen, the margins feebly serrulate ; disc convex,
without trace of costre, basal fovea moderately deep ; surface less coarsely punc-
tured than the thorax and not densely, those nearer the base rather coarser;
body beneath coarsely, not densely punctured, the ventral segments without

NORTH AMERICAN COLEOPTERA. 117

lateral umbone, the angles rather prominent, the last segment with entire mar-
gin ; prosternum not lohed in front ; anterior femur with an acute, not serrulate
tooth. Length .44 - .58 inch ; 11 - 14.5 inm. (Fig. 238.)

Male. — Antennae hipectinate (,238) from the fourth joint, the posterior or infe-
rior branch a little longer, terminal joint bifurcate; prosternum convex, coar.sely
sparsely punctured ; anterior tibia (242) slightly arcuate, very vaguely sinuate on
its inner edge ; middle tibia slightly arcuate, the posterior straight ; last ventral
segment (240) very vaguely emarginate at middle truncate each side ; last dorsal
short, coarsely punctate and entire.

Female. — Antennae simply serrate, the lower edge, however, broader than usual ;
pro.sternum as in the male ; anterior tibia scarcely arcuate, the middle and poste-
rior straight; last ventral segment (241) sinuately truncate; last dorsal coarsely
punctate, entire.

The dark markings on the elytra seem quite constant, and. are in
a general way as represented in the figure. The color of the body
beneath is as above. The male antennas present an unique structure
in the genus.

Five specimens have been examined, one only a male. It occurs
in Arizona and New Mexico.

49. C Ulkei Lee. — Form of atrifasciata, deep blue, the elytra with darker
spaces as in that species ; thorax more than twice as wide as long, widest behind
the middle, the sides in front rather oblique, posteriorly strongly]arcuate. Length
.60 inch ; 15 mm. (Fig. 243.)

This species is so closely related to the preceding that a few words
of description with some comparative remarks are all that seem
necessary. The foveas of the head, of which Dr. LeConte speaks,
are merely the spaces above and below the W-like line, which is less
elevated than in atrifasciata. The thorax is otherwise formed as
shown in the outline, although this is really less of a variation than
may be observed in such 'species as femorata. The sculpture of the
surface is less marked and the punctures less dense, Avhile those of
the elytra are rather finer and closer than in atrifasdata.

The only specimen I have seen is the type kindly loaned me by
Mr. Ulke. It is a female, and the ventral segments are as in atri-
fasciata. The antennae, however, present the usual form observed
in the genus, the free angles being truncate and not at all acute,
while the lower edge is no broader than normal. The antennal
structure alone induces me to retain the species as distinct, otherwise
I should have considered it an unusually stout female of atrifasciata,
as indeed it may ultimately prove to be.

One specimen, Texas.

118 GEO. H. HORN, M. D.

50. C prasiiiti n. sp. — Form moderately elongate, color above bright green,
beneath dark violet ; surface moderately shining, glabrous ; antennte 9 piceous,
gradually more slender to tip, third joint as long as the next two; front moder-
ately convex, coarsely not deeply punctured, occiput without carina; clypeus
(245) very broadly, not deeply emarginate, arcuate each side ; thorax posteriorly
very nearly twice as wide as long, sides very feebly arcuate, gradually divergent
from the front angles, slightly arcuate posteriorly, disc convex ; surface even
without fovepe or callosities, punctuation rather sparse, a little coarse toward the
sides ; elytra very little wider than the thorax, parallel, arcuately narrowed at
apical third, the margin serrate, the apices separately rounded ; disc regularly
convex, without costie or fovese, the basal fovea very feeble ; surface finely, indis-
tinctly and sparsely punctate; body beneath dark violet, the punctuation coarse,
feebly impressed and not dense, the flanks of the prothorax almost smooth, ven-
tral segments without callosities, the margin of the last ventral entire ; proster-
num coarsely not densely punctured, feebly lobed in front ; anterior femur with
a short broad tooth, serrulate on its distal edge. Length .26 inch ; 6.5 nmi.
(Fig. 244.)

Male. — Unknown.

Female. — Anterior and middle tibiie ( 247) slightly arcuate, the posterior straight ;
last ventral segment (246) with the apex rounded, entire, an ante-apical serrate
ridge, the terminal teeth on each side prominent ; last dorsal coarsely punctured,
entire.

A pretty little species readily known by its structural characters
and color. The contrast between the color of the upper and lower
surfaces is greater than I have observed in any other species.

One specimen from California, probably the northern regions.

* The name impressa has been used, although it was preoccupied by Fabricius
himself. Later Gmelin changed the name to tranquebarica, and two years after
Olivier proposed excavata. In accordance with the sti'ictest rules the name pro-
posed by Gmelin should be adopted, although it conveys an erroneous idea of
habitat. Inasmuch as the first impressa proposed by Fabricius is now placed in
Halecia, it might be as well to allow the Chrysobothris to retain the name pro-
posed for it. It is better, at times, to violate the law of priority than perpetuate
an annoyance.

Stii<lie«« on the IVortli Amerieaii CHAIXIDID^, with
«le»<>erii>tioiis of new species from Florida.

BY WILLIAM H. ASHMEAD.

Jacksouvillc, Florida.
(Paper No. 7.)

Subfamily— LEUCOSPIN^.

liElJCOSPIS Fabr.

1. Liencospis aflinis Say, var. floridana Cresson.

One specimen of this variety was identified from 8outh Florida, it
measured nearly half an inch in length.
The species is very rare in Florida.

Subfamily— CHALCIDIN^.

SiTIICRA Spinola.

2. Siniera pnlohra Cresson.

This species was originally described by Mr. E. T. Cresson from
specimens from Mexico and Cuba.

I took and identified three specimens here last summer.

3. Sinicra biocnlata Cressou.

Originally described from Texas. I took two specimens in Florida
last summer.

4. ISinicra flavopicta Cresson.

I took two specimens of this species last autunm ; it was originally
described from Cuba.

5. Smicra torvina Cresson.

Two specimens of this species were bred from lai'VJe feeding on
oak leaves, with about fifty specimens of an undetermined ichneumon.

The chalcids made their appearance long after the ichneumons,
and they may be secondary parasites on it.

126 W. H. ASHMEAD.

Subfomily— PERILAMPINtE.

PERI1,A]»IPIS Latreille.

6. Perilainpis oyaneus Brulle.

7. Perilainpis Ii.yaliiiii$« Say.

8. Perilainpis triangularis Say.

I have taken here and identified specimens of all three of the
above species.

In studying the genus I notice the following synonyms :

Perilampis alexis Walker = P. hyalinus Say.

" entellus Walker = P. platygaster Say.

" lepreos Walker ~= P. triangularis Say.

The following species is undescribed :

9. Perilampis fulvicornis u. sp.

% . — Length .08 inch. Head and thorax brown-black with a slight metallic
lustre; head at ba.se metallic green and transversely wrinkled; face smooth im-
punctured, pubescent ; ocelli dai-k ; eyes brown ; antennae, scape more or less
metallic green and grooved beneath ; thorax coarsely, deeply punctate ; scutellum
long, highly elevated posteriorly with the tip obtusely i-ounded ; abdomen blue-
black, triangular, smooth and shining ; coxae and femora blue-black ; tibia? and
tarsi clear yellow ; wings hyaline, veins pale or slightly yellowish.

Described from one specimen captured at large.

This s{)ecies approaches nearest to P. hyalinus Say, but is at once
distinguished from it by its smaller size, more slender form and by
the yellow tibiae and tarsi.

Subfemily— EURYTOMINaE.

DEC'ATOMA Spinola.

10. Decatonia niaeulipes n. sp.

9. — Length .11 inch. Black, coarsely punctate and covered with short, white
pubescence; antennae black, with a dull yellow scape; legs: coxae and femora
black, except at tips ; tips with tibiae dull yellow, tibiae with a black blotch in the
middle, tarsi pale; wings hyaline, veins pale yellowish.

Described from one specimen bred April, 1885, from oak gall
Dryorhizoxenns florUJanus Ashm.

It is closely related to Decrdoma liyalipennis Walsh, but the yellow
legs and collar in that species readily distinguish it.

SYSTOIiE Walker.

11. Systole bracliyptera n. sp.

9 . — Length .12 inch. Slender, black, with the surface finely shagreened,
pubescent ; head more coarsely shagreened than the thorax, viewed from front

NORTH AMERICAN HYMENOPTERA. 127

triangular with mouth parts flull yellow ; eyes greenish ; antennte 9-jointed,
black, or piceo-black, the apex of pedicel and first flagellar joint yellow, the
mesonotum is twice as long as wide and transversely shagreened at base ; scutel-
lum coarsely but shallowly punctate ; legs piceous with coxse, knees and tips of
tibipe and tarsi dull yellow ; abdomen very long, pointed fusiform, the fourth
segment is unusually long, occupying considerably more than a third of the
whole surface, anus and tip of venter yellow ; wings hyaline, short and broadly
rounded, veins yellowish, submarginal vein about twice as long as marginal and
post-marginal veins combined post-marginal slightly shorter than marginal ;
stigmal vein clavate.

This interesting species is described from one specimen taken at
large last summer. It is the first species of the genus described in
our fauna.

ISOSO.^IA Walker.

12. Isofsoina gigautea n. sp.

% . — Length .1,5 inch. Black, punctate ; head wider than thorax ; antennap
9-jointed, brown, pedicel short, flagellar joints long, cylindrical, pubescent, pu-
bescence in whorls, first joint of flagellum longest and thickest, about five times
as long as thick, other joints about four times as long as thick ; abdomen black,
shining, petiole stout, as long as the posterior coxse ; legs a uniform dull yellow
with the posterior coxse black ; wings dusky hyaline, rather densely pubescent,
veins yellowish, the post-marginal vein very long.

Described from one % captured at large.

Subfamily— TORYMIN^.

CALiLrlMOME Spinola.

14. C'alliiiioine theon Walker.

15. Calliiiioine li!$sii$t> Walker.

I have identified both of these sjiecies from specimens captured at
large last summer.

SYNTO^flASPIS Forster.

16. Syiitoinaspi!!) californiea n. sp.

9 . — Length .14 inch ; ovip. .25 inch. Golden green, coarsely, deeply punctate ;
eyes brown ; antennae black, scape dull yellow ; coxae metallic green, legs rufous ;

Described from eight specimens (two % six 9 ) bred from Cynipi-
dous gall (Andi'iciis batafoides Ashni.)

19. Ormyrus antlricus n. sp.

9 . — Length .12 inch. This species is much more robu.st than the preceding
species, and the abdomen is not nearly so pointed, metallic green, finely, trans-
versely rugulose; antennse brown, scape pale; legs: the femora are dark brown,
the tibife rufous and the tarsi yellowish, posterior tibial spurs short; wings
hyaline, veins brownish.

Described from one 9 specimen bred from Cynipidous gall (An-

Subtamily— EUPELMIN.E.
ElJPEIiMUS Dalnion.

20. Eupelmii^i auratu!!» n. sp.

9 . — Length .11 inch ; ovip. .02 inch. Bright golden green, surface shagreened ;
antennae long, subclavate and obliquely truncate at tip ; thorax but feebly de-
pressed, inclined to scutellum ; scutellum declining, obconical ; legs bright lemon
yellow ; coxse metallic green ; wings hyaline.

Described from one 9 taken at large, and two 9 specimens bred
from the Cynipidous oak gall Andricus rugoms Ashm.

The lemon yellow legs and the clear hyaline wings at once distin-
guish this species from all others in our fauna.

NORTH AMERICAN HYMENOPTERA. 129

21. Eupelmas clryorhizoxeni n. sp.

% 9. — Length .10-. 14 iuch ; ovip. .02 inch. Apterous; head large, much
broader than thorax, nearly smooth, greenish metallic on face, bluish on vertex,
mentum black ; eyes brown ; antennae subclavate, 11-jointed, scape dull yellow,
flagellum blackish, hairy, thorax at sides and beneath reddish brown, above gol-
den green with violaceous reflections ; collar narrow, quadrate ; parapsidal eleva-

upper surface of femora and a blotch on the upper surface of tibise, in the middle,
dark brown, ungues black ; abdomen ovate, brown black, with a submetallic
lustre ; ovipositor pale.

Described from three specimens, one Z two 9 , bred May, 1885,
from Cynipidous oak gall Dryorhizoxenns ftoridanus % Aslim.

In one 9 the brown markings on upper surface of femora and
tibiae are almost entirely obsolete.

The only other apterous Eupelmid in our feuna known to me is
Eupebnus epicmte Walk., described in " Annals and Magazine of
Natural History," vol. xx, p. 20, but it differs so widely in size and
color that it cannot be confounded with this species.

22. Eupelmus sphsericephalus n. sp.

9 • — Length .14 inch. Blue-black, long and slender, finely punctate ; head
nearly spherical when viewed from above ; face rather thickly covered with
short, white pubescence ; eyes dark ; antennse subclavate, including scape, black

25. Eu]>eliiiu!>4 quercus n. sp.

9 . — Lenjitli .18 inch ; ovip. .05.

This species so exactly resembles EupebnuH mirabilis Walsh, in
size and general apjDearance, as to be I'emarkable, and were it not
for the exserted ovipositor, might easily be confounded with that
species.

It is at once distinguished from it, however, by the yellow exserted
ovipositor, by the pleural pieces being black, and not rufo-i)iceous as
in mirabilis, and without the white band at base of abdomen. There
is a large brown blotch across wings leaving the base and tip hyaline.

Described from one specimen taken on an oak in April, 1881.

26. Enpelinus zeli n. sp.

9 • — Length .10 inch ; ovip. .10 inch, yellow. Head and thorax finely sha-
greened and dark metallic green ; eyes hrown ; antennse pale brown ; collar short,
triangular; mesouotuni with parapsidal grooves well defined, posterior raised
lobe convex, hluish, raised parapsides, pleural pieces, sternum, cox» and legs
rufo-piceous, scutellum and scapulse bright golden ; middle tibial spur as long as
first tarsal joint, first, second, third and fourth tarsal joints with black teeth
beneath, spur and tarsi yellowish, upper edge of posterior tibise blackish ; abdo-
men blue-black, with some long pubescence towards the tip ; wings hyaline, with
two transverse brown bands.

Described from two 9 specimens bred April, 1885, from the eggs
of the hemi})teron Zehis longipes Linn.

terologische Studien II Chalcidias und Proctotrupii p. 145," and this
is the first species described in our fauna.

A Review of the species describetl by Olivier in the
*• Eutomologie."

BY GEORGE H. HORN, M. D.

In the folloAving pages it is proposed to pass in review the species
described by Olivier, whether originally by himself or by quotation
from others, cited from our fauna. These species have been gone over
so frequently in past years that it seems to have been assumed that
nothing remained to be done. Really comparatively little new will
be found in the following pages, but it is deemed sufficient to warrant
the publication of the entire list.

The " Entomologie" consists of six large quarto volumes of text
and two of plates, which bear date as follows : vol. i, 1789 ; vol. ii,
1790 ; vol. iii and iv, 1795 ; vol. v, 1807 ; vol. vi, 1808. In the first
four volumes the different genera are treated as if distinct pamphlets,

136

GEO. H. HORN, M. D.

each having its separate paging. The genera are numbered continu-
ously throughout the work, and by a little manipulation are made
to count an even hundred. The last two volumes have a continuous
and continued paging. The entire work is one of the most trouble-
some from which to make a citation of any in the entire range of
entomological literature.

In the following pages the volumes are treated separately. The
number following the generic name is that used by Olivier, that fol-
lowing the species is the J^age subordinate to the generic number. In
the vast majority of cases the Olivierian species merely require a
change of generic name. In some instances the specific name is a
synonym, and it will be observed, especially among the Chrysomelidse,
that we are at present using names of a more modern origin for
many of the Olivierian species, in which case the name to be dropped
is in italics. Tbe number about which any doubt remains does not
exceed ten, the entire number enumerated being a little more than
three hundred.

[4] — Is the variety entirely pale above with the suture ferruginous
brown, wider at base.

[5] — Graptodera polita Oliv., is an olive green species of the size
and form of foliacea. The elytra are scarcely visibly punctate, the
thorax with feeble transver.se impression. The antenna? and legs are
rufo-testaceous, the hind femora piceous. I know but one other spe-
cies in our fauna with pale legs, G. fuscoceuea Mels. This is much
smaller and more robust, the elytra very distinctly punctured.

[6] — This is the larger variety of quercata in which the elytral
markings are broken into vittae.

Colaspis by the sides of the thorax entire, while in the latter genus
they are subbidentate or undulate.

Summary.

In glancing over the preceding list of species it will be observed
that the vast majority had been previously described by Fabricius,
Olivier himself coming next in order, while a few are cited from
Linnaeus, De Geer, Drury, Swederus and Herbst.

The greater number of specific names still remain valid, the only
change necessary being the addition of the more modern generic
name. In a few instances the names proposed by Olivier seem to
have been lost sight of and the species have been renamed by later
authors. In a few instances species foreign to our fauna have credited
to it and on the other hand some of our natives have been located
elsewhere. The result of the preparation of the above list is the reduc-
tion of the number of doubtful species very nearly to the lowest pos-
sible limit.

Additional Notes.

While going over the Ulivierian s^pecies my attention was directed
to the species described by Say under the name Colaspis as follows :
C. pretexta Say, is Rhabdopterus picipes Oliv.
C ovata iSay, is Chrysodina globnsa Oliv.
C. convexa Say, is a Nodonota and has been placed as a synonym

of N. tristis Oliv., but iueorreetly.
C. striata Say, is Paria aterrima Oliv.

C. puncticollis Say, is a Nodouota, and has since been described as
N. strigicollis Lefev. ; it may be known by having the sides of
the elytra obtusely subcarinate behind the humeral umbone ;
the legs are usually pale, but vary to piceous.
C. decemnotata Say, is a Xanthonia.
C. sexnotata Say and
C. quadrinotata Say, are varieties of the same, and identical with

Paria canella Fah.
C. pallida Say, is a Metachroma.

C. dubiosa Say, was placed by Crotch in Metachroma, which, as con-
stituted by him, is apparently composite, and the species should
be separated.
C. favosa Say, is a true Colaspis.
C. denticollis Say, is a Myochrous.
C. interrupta Say, has been placed in Metachroma.

Lefevre has described a Typophorus histrio from our fauna, which
seems identical with Say's species. I have not yet had the time to
study closely the genera of Eumolpidae as given by Lefevre (Mem.
Liege xi), but it is possible that 3L califormca, dahiosa, usta and in-
terrupta should go to Typophorus.

At present is a favorable opportunity for directing attention to the
collection of the species or forms associated in our present lists under
the name Colaspis tristw or Nodonota, as it should be called. In the
series at present before me at least five forms are clearly separable in
those occurring in the Atlantic region, while at least two occur in
Arizona. In all the species before me I have observed that the sixth
joint of the antennae is distinctly shorter than either the fifth or
seventh.

In collecting Nodonota the plant on which they occur should be
noted, and as large series from remote regions will be necessary for
the proper elucidation of the species I have refrained from greater
expression of opinion.

Descriptiou<!> of new PYRAL,ID.E.

BY GEO. D. HULST.

Some two years since I was led to endeavor to make a special
study of the Geometridce and Pymliche. The principal part of the
work done by me up to the present time has been in the first family,
— but I have been looking somewhat into the Pyralidce and collecting
at the same time, and a very considerable amount of material has
accumulated, for which I can get no names. That it may be handled
and in time classified, is the object of the present descriptive paper.
The most of the Pyralidce already described are determined in the
different American collections. The National Museum has a very
considerable collection l)y Belfrage, with Zeller's determinations I
believe, though, coming tlirough several hands, I am not able to say
how much reliance can be placed upon them. Mr. Henry Edwards
has some types, and many typical specimens of Mr. Grote, from the
Pacific Coast, and his whole collection has had the advantage of Mr.
Grote's determination. Prof. Fernald has the advantage of having
the most, if not all, of Packard's, Grote's and Zeller's types identified.
So, though Mr. Grote's types went to the British Museum, the loss
is in ])art remedied by the possession of typical specimens. A large
number of Lederer's, Guenee's alid Walker's species have been de-
termined, but quite a large number (almost all of them from the
East and South) are yet, after from twenty-five to thirty years, un-
identified. Some of them undoubtedly can never be determined.
My material described below has been through the hands of our best
American specialists, and has come back to me marked or declared
" unknown to me." So, making use of the knowledge of others as
well as giving faithful study myself, I publish the following as new
species.

Botis scurralis sp. nov. — Expands 28 mm. In general coloration like B.
perrnbraUs Pack., but differing as follows : In perrubralis the ground is yellow
washed with red, and there are two fine red cross lines. In this species the ground
color is even canary yellow, and this color is immaculate, save by the faint discal
spot. In perrubralis the outer band is bright reddish brown, being darker next to
median space ; the costa is edged with the same color ; there is a broken yellow
marginal line, and the fringes are dark reddish brown. In scurralis the outer
band is clear pink, uniform ; the costal band is of the same color, ^jnd is much
broader than in perrubralis. There is no marginal line ; posteriorly there is a
fading of the pink into a broad subterminal band, and the fringe is fuscous, be-
coming yellow posteriorly. In perrubralis the baud on the hind wings extends
only two-thirds across the wing and in my specimens ends abruptly and is red-
dish fuscous. In scurralis it generally reaches anal angle and fades posteriorly
along margin into light ochreous. These differences in part hold good for the
under side.

seurra/is may be a variety, but it holds its own in Arizona, and I

dian basal spot; a white subcostal line reaching out from base nearly half the
length of wing ; orbicular and reniform present, with white space before, between
and following them ; an outer black line, sinuous, edged outwardly with whitish,
which is broken into rather large spots by the blackish veins, each of these spots
dentate outwardly and there edged with black ; two corresponding spots within
the outer line in the bottom of sinus ; apex ochreous, rounded ; margin black ;
fringe light fuscous, white at outer angle ; hind wings semi-hyaline with basal
line angulated at middle ; outer and submarginal lines very dentate ; all lines
fuscous, submarginal space with an ochre shading ; margin black, fringe white ;
beneath generally lighter, but with a broad, dark, fuscous, marginal band.

One % , New York. This insect is not properly a Boti.-f, but like
a few above, and some to follow. I can find no satisfiictory home
for it in any genus after a study of Lederer and other systematists.
In many cases I have not been able to make a complete examination,
in view of the scarcity of material, and the fact that, very unfortu-
nately, nuich of it is not my personal property.

Its coloration is rather aberrant for this group ; it is certainly not a

antennae would place it close to Pyenarmon Led. ; its legs might make
it congeneric with Antigastra Led. If I had arrived at the point of
genus making, this with several others would give a fair field for
effort.

A generic $iyiiop!<iis of the hyineiiopterous Family
PRO< TOTRl PIDJE.

BY L. O. HOWARD.

This large family has been but little studied in this country, al-
though considerable material for study is to be found in the various
collections. I have been able to pay but little attention to the gi'oup,
and this synopsis is nearly a literal translation of that which appears
in Part II of Dr. Foerster's " Hymenopterologische Studien,"
Aachen, 1856. I have inserted, however, several of his more re-
cently erected genera taken from his " Kleine Monographien," and
also one or two others which have been described since. The divi-
sion into subfamilies which immediately follows is faulty in the ab-
.sence of the subfamily BETHYLiNiE, a generic synopsis of which is
included later. My excuse for this omission is ignorance of the gen-
eral characters of this subfamily, which, together with the Embo-
leminae, is omitted by Foerster frorn his subfamily synopsis. I
have been unable to find a copy of Haliday's " Hymenojiterorum
Synopsis" in America in which the characters of this subfamily are
presumably given, and while this synopsis is being printed Prof
Riley is kindly searching for this paper in English libraries. I am
advised, however, not to defer publication on this account. I have
prefixed an asterisk to those genera, species of which have been
published as found in America north of Mexico, and a dagger to
those which I have myself recognized in collections (mainly in Prof
C. V. Riley's, now the property of the National Museum by dona-
tion), but which have not yet been published as American. Of
the one hundred and thirteen genera mentioned in the synopsis,
but twenty-nine have thus far been found in this country.

Sublhinily Hp:lorin.«.

This subfiuiiily consists only of the genus Helorus Latreille, which
is sufficiently characterized in the subfamily synopsis. One unde-
scribed species of the genus has been collected in this country. A
single specimen was sent me by Mr. Cresson labeled " Canada."

The genus Copelus Provancher (Petite Faune entomologiciue de
Canada, II, 539, 1883), seems, from the figures and description which
Mr. Provancher gives, to be identical with Helorits. The author
places it with the Braconidae, and says : " The singular arrangement
of the wing- veins with these insects renders them at once remarkable.
The form of the abdomen would seem at first to place them with the
Proctotrupidj\3, but the perfect venation of the wings excludes them
from this fi\mily."

The proper position of this genus has been a matter of considerable
dispute. The full venation of the Avings and its evident high or-
ganization must place it at the head of the Proctotrupidae. The
species which I have seen bears a strong superficial resemblance to
the Sphegid genus Tiphia. Its habits are those of a parasite, and
H. anomalipea Panz., has been bred from the pupa of a Hemerobim.

NORTH AMERICAN HYMENOPTERA. 179

91onograph or the ]VIUTIL,L<IDi£ of North America.

BY CHARLES A. BLAKE.

The accumulation of much new material, in this interesting family,
from all parts of the country has suggested a revision of the " Sy-
nopsis" published in the "Transactions" in 1871, which, although
tolerably complete at that time, the subsequent discovery of new
species and also of a new genus, together with changes in nomen-
clature, have rendered a review of the work both necessary and de-
sirable.

Full descriptions of all the species known to me are given, and of
those that have not been identified descriptions are added, in most
cases in the author's own words, thus assisting the student to identify
his material without the necessity of consulting scientific works,
which are often published in foreign languages, and generally diffi-
cult of access.

The MutillidEe, unlike the Formicidte, or social ants, are solitary
in their habits, and usually found in hot sandy situations. The spe-
cies of the genus MnfUla are now well known to be parasitic, espe-
cially on various species of Bombas, and it is presumable that those
of the other genera of the family are likewise of the same habit.

The characters of SpJutrojjJiiha/ma, which was treated as a subgenus
in the "Synopsis," appear to be sufficiently constant and distinct to
warrant its elevation into a genus ; the smooth, round eyes separating
it at once from Mutilla, which have the body less coarsely sculjitured
and not so densely hirsute.

The selection of the name Agama used for a genus erected for the
reception of those species characterized by the more or less shining
unicolorous body, unusually large eyes and ocelli, and hyaline wings
was unfortunate, as it was preoccupied in the Reptilia, a fiict over-
looked at the time. The name PhoiojisiH is therefore substituted.
Of this genus the males only are known, and it is possible that the
females, which have thus far escaped the observations of collectors,
are larviform and subterraneous in their habits.

Chjphotex is the name I propose for a new genus, characterized
by the binodose thorax and petiolate abdomen, the first segment of
which is very slender at base and suddenly dilated and nodose at
apex ; the eyes are smooth and round, as in SpJucrophthahna, while
the absence of ocelli separated it from 3Iyrniosa.

180 CHARLES A. BLAKE.

The genus Apterogyna, which does not appear to have been found
in North America, is remarkable for the two anterior segments of
the abdomen being constricted and nodose, and for the great length
of the antennae in the male, being nearly as long as the body, and
for the curious neuration of the wings.

The genus Bradynolxenus, also exotic, is characterized by the large
quadrate head, having the anterior and posterior angles acute, and
the thorax of the female being divided in two parts ; the femora and
tibiae are more robust than in the other genera of the family.

In Myrmom the head is subglobose, eyes small and round ; the
thorax ovate and the anterior wrings have one marginal and four
submarginal cells. The females of our species appear to be unknown.

In the genus Methoca the ocelli are said to be distinct in both sexes,
head subglobose in the female, transverse in the male, eyes ovate,
thorax trinodose in the female and oblong in the male.

Nothing definite appears to be known of their habits, although
they are supposed to be parasitic. Owing to the dissimilarity of the
two sexes Latreille considered the male belonging to a distinct genu.;,
Tengyra, which was arranged among the Scoliidte.

I have divided the family into nine genera, in all of which the
females are apterous, and may be tabulated as follows :

Antennae of male flabellate 1, I'Maiiiiiiotherina.

Antennae simple in both sexes.

Eyes ovate, emarginate in the male, entire in the female 2, Mtitilla.

Genus 1, PSAMMOTHERMA Latr.

This is distinguished from all the other genera of MutillidfB by
the male anteuiice being; flabellate. The neuration of the anterior
wing is much like that of the first division of the next genus (fig. 1),
except that the third submarginal cell is not hexagonal, but rather
subtriangular, shaped considerably like that of oceldentaUs (fig. 2).

This is only the second species of this genus so far known, the first
l)eing from Senegal, the P. jlabeUata Latr., which differs by the second
abdominal segment being ferruginous.

Genus 2, MrTIL,L.A Linu.

Male. — Head usually transvei'se and compressed, eyes moderately
large, ovate, more or less emarginate, but in a few species they are
entire. The ocelli placed in a triangle on the vertex. The antennse
subfiliform, gradually tapering to the apex, which is acuminate, in-
serted on the sides of the base of the cly]3eus. The mandibles ar-
cuate and tridentate, but varying occasionally in this respect. The
prothorax extending laterally to the origin of the wings ; the tegulae
usually very large. The anterior Avings with one marginal and three
submarginal cells, the marginal usually of a semi-circular form ; the
three submarginal cells subequal, the second and third each receiving
a recurrent nervure, the second nervure being almost obsolete, as
well as the third transverso-cubital nervure, from the middle of which
emanates a more or less abbreviated nervure, never extending to the
apex of the wing ; in a few exotic species the third submarginal cell
is obsolete. The legs moderately long and pubescent. Abdomen
ovate, the first segment subpyriform or sometimes }>etiolate, the second
campanulate, and the apex curved.

Female. — Head suborbiculate, or subquadrate, sometimes enor-
mously developed and armed beneath with two or more formidable
spines ; the ocelli always wanting, the eyes ovate, entire ; mandibles
arcuate and usually unidentate. Thorax longitudinal and truncate
interiorly and posteriorly ; in some exotic species much narrowed
behind. Legs more robust than in the male and armed exteriorly
with spines. Abdomen similar to the male.

The species, which are not numerous, may be divided into three
divisions, viz. :

This is a very variable and abundant species ; in some individuals
the legs are ferruginous, and without the dark spot on the second
abdominal segment, while in some instances there are indications of
small lateral spots, and occasionally the disc of the thorax and ab-
domen beneath is testaceous. Its geographical range is quite ex-
tended, being found from Maine to Texas, and westward to California.

It resembles *S'. simU/ima Smith, but is recognized by the more
elongate thorax, which is narrowed behind, and the smaller head ;
the head in simU/ima being broad and quadrate.

Upon the examination of a large series of specimens this may
prove to be only a variety of ferrugata. It is, distinguished by the
more or less distinct pale spots on the second abdominal segment ;
thorax is rather shorter and broader, and the color of the apical
fringe of the segments varies precisely as in jerrugata.

ovate, prominent and lateral ; the stemmata large, placed in a tri-
angle on the vertex ; antennae filiform, tapering to a point at the
apex ; the scape very short ; the joints of the flagellum beyond the
third subarcuate ; thorax oblong, the collar extending to the inser-
tion of the wings ; the metathorax obtuse ; the anterior wings with
one elongate marginal cell, which is pointed at its apex and extends
nearly to the tip of the wing ; three submarginal cells, the first as
long as the two following, receiving the first recurrent nervure ; the
second quadrangular, receiving the second recurrent nervure ; the
third extending to the apex of the wing ; abdomen linear, the seg-
ments subcrenate ; the hypopygium produced laterally into two ver-

at the lateral posterior margins of the clypeus, rather longer than the
thorax ; the clypeus triangular ; the mandibles arcuate ; the thorax
elongate, doubly strangulated, rounded at the base and apex ; legs
long and slender, the coxte very robust ; femora subclavate ; the

The abdomen does not contract abruptly to the petiole, but sub-
sides gradually. Van der Linden says that the species of this genus
are the females of species of Tengyra.

9Iethoca Poeyi Guer.

3Iale. — Black, without spots, with some whitish hairs ; the metathorax is
slightly rugose and truncate ; wings hyaline, the nervures black, the two trans-
verso-cubital nervures, which from the second submarginal cell, are not parallel,

Resembles Sanvifali Latr., but is larger, with a much larger stigma
and each abdominal segment is much more contracted before its pos-
terior incisure. (Say.)

DIPTEROL.OGICAI. ]¥OTES AND DESCRIPTIONS.

BY S. W. WILLISTON.

LEPTID^.

Symphoroinyia pachyceras n. sp.

3Iale. — Opaque black, first anteunal joint very much thickened; wings yellow.
Length 5-6 mm.

Antennse black, first joint very much thickened, bushy black hairy. Face gray
polliuose, but mostly concealed ; palpi porrect, bushy black pilose. Dorsum of
thorax opaque black, with only faint indications of brown stripes and with long
black pile ; abdomen opaque black, in front and on the sides anterioi-ly with long
yellow pile, posteriorly with black pile. Legs blackish pitchy ; tarsi mostly black.

sometimes divided by a line. Abdomen brownish gray polliuose, nearly bare.
Legs black, knees narrowly luteous. Wings nearly hyaline, stigma brown.

One male and three females. Northern California. The females
differ very much from the male ; I believe they belong together,
nevertheless.

iSyinphoroniyia plageiis n. sp.

3Iale. — First antennal joint much thickened, third yellowish red; abdomen
shining metallescent black ; wings brownLsh clouded ; femora black. Length
7 mm.

First antennal joint much thickened and bushy black hairy, black, gray pol-

Two specimens, Washington and Mt. Hood, Oregon.

ASILID.E.

Ceraturgn^i iiigripes u. sp.

Male. — Abdomen with golden pollinose posterior cross-bands; legs black.
Length 14 mm.

288 S. W. WILLISTON.

Antennse in structure like those of C. cruciatus, the style somewhat shorter;
hlaek, the first joint bushy black hairy, the second joint less so. Face projecting
a little more below than in C. cruciatus; densely light golden yellow pollinose,
and with long, soft, rather abundant light yellow pile below, extending up more
thinly in the middle ; occiput below with silky white hair ; above, the occipito-
orbital hairs are black, longer and more abundant than in C. cruciatus ; front
shining black, with black hair, except some yellowish ones on the ocelligerous
tubercle, the orbits narrowly golden pollinose. Dorsum of thorax thickly golden
pollinose, leaving two not very broad, median, brownish black stripes, separated
by a line, and on each side two large, oval, black spots narrowly separated by a
sutural line ; pile or hair rather long and erect, on the front part yellowish white,
broadly behind black, the bristly hairs of the post-alar callosities and the scutel-
luni light yellow ; pleurae thickly light yellow pollinose, below and on the coxse
more grayish. Abdomen in shape like that of C. cruciatus, with short, but abun-
dant, erect light yellow pile ; each segment with an opaque, light golden yellow
posterior cross band, composed of dense pollen, moderately narrowed on the
sides ; that on the first segment narrowest, that on the second comprising about
oue-half the segment, on the last leaving only a slender anterior black band.
Legs pitchy black, the tibiae and tarsi fulvous pubescent; pile of the coxse, espe-
cially the front ones, and of the femora below, long and silky white. Wings
nearly pure hyaline ; neuration as in C. cruciatus.

One specimen, Georgia. The thorax and abdomen in shajje and
markings are singularly like those of Laparas pictitarsis Bigot. The
'' pedes flavr prevents the identification with the long-lost C. auru-
lentus Fabr.

Iflyelaplilis lobicornis O. Sacken. Western Dipt. 287 ; Williston, Tians.
Am. Eut. Soc. xi, 7 ; xii, 53.

Either there is a number of closely allied species, or else a con-
siderable variation in the one. The fourth posterior cell is in some
cases wide open, in others narrowed, while in yet others it may be
closed and petiolate. I have seen a specimen ( % ) from California
in which the abdomen is wholly black, the femora at the base blackish
and the tip of the tibise and all the tarsi black. The fourth poste-
rior cell is closed in the margin ; otherwise, the specimen is quite like
the one I first described.

myelaphus rufus Williston, Trans. Am. Ent. Soc. xi, 7.

I have seen a male of this species in which the wings, as I sus-
pected, are wholly blackish, except the very base. The fourth poste-
rior cell is closed in the margin and the second joint of the antennae
is reddish.
Dioctria pusio O. Sacken, Western Dipt. 288.

A male specimen from Colorado I refer to this species. The coxae
are yellow, the tip of the hind tibise considerably incrassated and the

NORTH AMERICAN DIPTERA. 289

slender abdomen has the third and following segments broadly l)lue-
lilack on tlie disk of each, the margins yellowish red, the seventh
almost wholly, the hypopygium entirely so. The four front tarsi are
also brownish, excei^t the base.

^iteiiopogon icacidiuus n. sp.

Male. — Black; abdomen, except base and hypopygium, yellowisli red; wings
black ; mystax white. Length 14-1.5 mm.

Like species of Ospriocerus, but the antennse with a distinct terminal style.
Face wholly densely grayish white polliuose, the bri.stles of the mystax white:
frontal and occipito-orbital bristles black, beard and long hair of the anterior
coxffi white. Dorsum of thorax moderately shining, brownish black, on the sides
grayish or browni.sh yellowish pollinose, behind and on the scutellura less thickly
so, in the middle with not very noticeable stripes. Abdomen slender, yellowish
red, the first, second, and anterior angles of the third segment and the hypo-
pygium black. Legs black, the front femora more or less, the front and middle
tibife and tarsi pitchy or reddish. Wings black.

This species has a very different aspect from other Sienopogoiies,
but the presence of a well-developed cylindrical antennal style, pre-
vents its location among the Ospriocerl. It differs from the known
species of Os})rioceri(s also in the possession of long white hair on
the anterior coxae.

Three specimens, Kansas Plains ; taken in a grassy ravine, Aug. 20.

13 [Bigot].

I have compared specimens of this species from New" England,
Kansas and Southern California and find no differences. I believe
the synonymy above may be safely accepted.

Triclis tagax Williston, Trans. Am. Ent. Soc. xi, 8.

A male specimen of this species, received without locality, differs
in having the pollinose bands of the abdomen confined to a spot on
the hind angles of the segments ; the last two segments red on the
hind margins. On each side of the front margin of the dorsum of
the thorax there is a large light brown pollinose spot extending back
narrowly above the dorso-pleural suture.

Saropogoii u. sp.

I have specimens of a species of this genus (California) with widely
open fourth posterior cell, of which the abdomen is as slender as that

TRANS. AMER. KNT. SOC. XIII. (.37) OCTOBER, 1886.

290 S. W. WILLISTON.

of the most slender species of Deromyia known to me. Species with
this cell widely open belong here, and those wdth it petiolate with
Deromyia ; but, as an actual fact, not a few species will be found in
which this character is variable ; indeed, my specimens of S. adustus
and combustus have the cell closed ; there is absolutely no discovered
character that wdll separate the genera. Still, the multitude of spe-
cies (I have seen more than thirty, chiefly from the United States)
of Deromyia renders its retention almost imperative.

Liapliria pubescens Williston, Traus. Am. Ent. Soc. xi, 32.

I have seen specimens of this species, collected by Mr. Morrison,
bearing the label "White Mountains."

Atoiiiosia (Atractia) Mikii n. sp.

3Iale. — Black, shining, white pilose ; middle tibife slender, with long bristles,
at the tip dilated and black pilose ; wings cinereous hyaline. Length 6 mm.

Front, face and occiput clothed with whitish gray pollen ; on the lower part
of the face with a silvery reflection ; beard and thin pile of the face silky white;
mystax not abundant, soft, white. Antennae black ; first two joints of equal
length, short, with black bristles; third joint elongate, of nearly equal width
throughout, truncated at tip, and provided with a slender style, about a third
as long as the joint. Dorsum of the thorax and scutellum shining, with silvery
pubescence, the bristles black. Pleurse densely white poUinose, with a shining
black spot on the mesopleurge, the trichostical bristles white; tegulse yellow.
Abdomen black, shining, finely punctulate, the pubescence or short pile on the
posterior angles and borders white. Legs black, the tarsi largely reddish ; all
the tibife and tarsi with long, chiefly black bristles, on the outer side of the
middle pair with two very long and two shorter ones; the middle tibiie are
slender to near the tip, where they are dilated and provided on the outer side
with a tuft of black pile ; the middle metatai-si slender on the basal part, with a
small tuberosity near the base below ; hiud tibite on the inner side with short,
white and thick pile, as in Dioctria. Wings a little clouded ; first posterior cell
not coarctate.

Hab. — San Domingo.

This species differs distinctly from the three known South American
ones of Atractia in the pubescence, scutellum, legs, etc. The peculiar
structure of the middle legs in the present species is not mentioned
in any, though it is probably a sexual character, and the sex is not
given by either Wiedemann or Schiner ; nor can I tell of which sex
my specimens are, though I think they are males. So far as the
location of the genus is concerned, I object to placing it among tlte
Asiliiue,. My species is an Atomosia with a terminal antennal style,
and must be placed in the immediate vicinity of that genus. I take
much pleasure in dedicating this s])ecies to the distinguished Austrian

NORTH AMERICAN DIPTERA. 291

dipterologist, Professor Mik. Schiner speaks of a "Griffel" in the
South American Aiommia cydocera Sch. (Nov. Exped. 170) and in
his descri])tion of A. m-gyrophora he says the species is quite like an
Atmetia, save in the structure of the antennae, so that it is difficult
to say what the genus Atractia really is.

MIDASID^.

Leptoinidai^ paiitlierinus Gerstsecker, Stett. Eiit. Zeit. 1868, 85; Osten
Saeken, Western Dipt. 280.

The male of this species differs very much from the female in
coloration, and, had I not received specimens collected together, I
would have believed them specifically different. In the male the
head, thorax and antennae are black, the pile is longer and more
abundant, and the constriction of the basal part of the lamella is
less evident, the black bands of the abdomen are broader and the
hind femora are sometimes largely blackish. The knob of the hal-
teres in the female is brown ; in the male black.

Four specimens, Washington, California.

Jflidas luteipeiiuis Loew, vii, 23.

I have seen specimens of this species from Arizona (Professor
Comstock, No. 148).

Midas militaris Gerstsecker, Stett, Ent. Zeit. 1868; M. vittatus Macquart
(lion Wiedemann), Dipt. Exot. 4e Suppl. 60, pi. iv, fig. 6; Bellardi, Saggio, etc.
ii, 7 (id.)

A number of specimens (Professor Comstock, No. 149) from Ariz.,
evidently of this species, show a considerable variation in coloration.
The lamella is sometimes red, the thorax varies from a coffee-black
to a red. The black spot on the sides of the abdominal segments
is sometimes wanting, and the venter and legs vary from red to
nearly black.

91idas scitulns n. sp.

M<de. — Black, abdomen with yellow bands ; lamella of antennae elongate ;
wings nearly hyaline, brown along the costa. Length 15 mm.

Antennse black ; lamella considerably longer than the first three joints together,
broadest at the base, sinuate, and then gently tapering to near the tip. Head
black ; face broad, below and the oral margin deep red ; pile short, not abundant,
white. Dorsum of thorax opaque black, nearly bare ; the lateral margins, humeri,
post-alar callosities, scutellum and metanotum dark yellowish or brownish red ;
pleurre shining, more or less pitchy red. Abdomen shining bluish black, with a
yellow and reddish yellow posterior cross band on each segment ; the anterior
angles, extending narrowly across the front part of the anterior segments, reddish

yellow. Venter yellow fasciate at the incisures. Legs dark pitchy black, the hind
pair more reddish ; hind femora considerably thickened on outer part, more
slender and arcuate toward the base, below with short spines ; hind tibise straight,
produced into a small spur below. Wings nearly hyaline, with dark veins, nar-
rowly clouded with In-own along the costa.

One specimen, Arizona (Professor Comstock, No. 152).

Ectypiis linibatus n. sp.

Female. — Clay yellow; thorax reddish; veins of the wings clouded with
brown ; abdomen light-yellow fasciate. Length 22 mm.

Antennae orange-red, the third joint, except its base, blackish ; lamella shorter
than the third joint, tapering on the middle to the base. Head red, in the mid-
dle of the front blackish; the sides of the front, the face, and the posterior orbits
thickly light yellowish gray pollinose ; pile sparse, silky white ; proboscis short,
blackish, labellse broad. Thorax opaque reddish cinnamon-brown, the humeri and
pleuraj more yellowish ; dorsum with two stripes of sparse white pubescence :
just above and below the dorso-pleural suture two spots of whitish pollen and
another on the sterno-pleurre. Abdomen luteous yellow, shining, the first four
segments with a rather broad posterior light yellow margin ; terminal segments
cylindi-ical, the ovipositor with about twelve short rays ; legs yellow through-
out; hind femora elongate, only slightly thickened, gently arcuate, with two
rows of spines below ; hind tibiae straight, not produced into a spur at the tip.
Wings with broad, dark brown clouds on the veins.

One specimen, Arizona (Professor Comstock, No. 149). This spe-
cies agrees throughout in its general characters with the description
and figures given by Gerstaecker (Stett. Ent. Zeit. 1868) of his genus
Edypus, and, so far as the female characters indicate, evidently
belongs to this genus. The tyj^e and only other known species of the
genus, so far as I am aware, is E. pinguls Gerst., from Africa.

NEMESTRINID.^.

Hirinoiieiira flavipes u. sp.

i^emrtZe.— Black, thickly pollinose; anteunse and legs yellowish; wings nearly
hyaline, narrowly luteous in front; two submarginal cells, both open, fourth
posterior only closed. Length, with ovipositor, 15 mm. ; without, 1.3 mm.

Eyes bare, large, their inner borders nearly parallel, the face a little narrowed
below. Front narrow, only a little wider below, a little shining, with grayish
pollen and black pile ; most projecting above the base of the antennse, thence
receding to the oral margin ; above, on each side of the ocelli, deeply excised.
Antennje situated below the middle of the head in profile, short, joints of nearly
equal length; the third cordate; pile of basal joints yellow and blackish; face
narrowly and deeply grooved on each side near the eye, in which grooves the
slender, cylindrical, yellow palpi are closely lodged, reaching nearly to the an-
tennae; face with sparse yellowish pile, but that of the palpi longer, blackish;
proboscis short. Thorax black, but mostly concealed beneath uniform, tliick.
grayish brownish dust; pile erect, moderately abundant, not long, lutescent yel-
lowish. Pleurae, pectus, and venter thickly covered with light gray pollen, the

NORTH AMEEICAN DIPTERA. 293

pile whitish. Abdomen like the dorsum of the thorax ; at the base, witli yellowish
pile, beyond with a short, reclining, sparse black hairs; a narrow band at the
base of the second segment, gray polliuose, beyond it a broader brown band;
ovipositor directed backward, composed of five segments, their entire length
about equal to that of the two preceding segments together, forming a tapering
continuation of the abdomen, the last one elongate, reddish, and split nearly to
its base. Legs light yellow, the tip of four anterior tarsi, the tip of hiud femora
and the rest of the hind legs reddi.sh.

The thorax, abdomen and wing-neuration are like those of Trich-
ophthahnia A^ovm HoUangce Macquart, as figured in pL ii, fig. 7, Dipt.
Exot. ii, 1. The last segment of the ovipositor is not as long. I de-
scribed the eyes as bare, but, by looking across the under part with a
good lens, a few scattering hairs are visible, and it is possible that in
the male they may be more distinctly pubescent. This is the fourth
species of this family now recorded from North of Mexico, viz.,
Hirmoneura {Parasymmiclm) clausa O. S., H. flavipes, Rhynchoceph-
alm /Sackenii Will., and B. volaticus Will. In my description of the
last species I should have described the "black" pile of the abdomen
as dark chocolate-brown, and the " white" tomentum as glistening-
light yellow.

THEREVID^

There va v talis O. Sacken, Western Dipt. 274.

I have several specimens of this species from Washington Terri-
tory. In some the blackish bristles of the vertex and front are want-
ing ; in others the pile of the thoracic dorsum is in large part black.
A female with them, and which seems to be of the same sj^ecies, dif-
fers in having the pollen above more brownish, and is as usual less
pilose ; it is most especially characterized, however, by the presence
of two large, round, deep velvet-black spots on the front

Tliereva crassicoriiis n. sp.

Jl/(//e.— Black, white pollinose and pilose; the thickened first antenual joint
thickly black hairy above; vertex and thoracic dorsum black pilose; front bare;
wings hyaline, stigma and narrow clouds of the discal veins brown. Length
9-10 mm.

Eyes separated only by a sutural space, front bare of pile. Antennae black, the
first joint pollinose, above with long black hair and bristles, below with black
.bristles and white (jile. Head below densely white pilose and with sparse
black hairs ; occipito-orbital bristly hairs black. Dorsum of thorax in the middle
with three slender pollinose stripes, enclosing two opaque dark ones; on the
sides blackish and pollinose; pile black. Pleurpe thickly white pollinose and
pilose. Abdomen thickly wdiite pollinose and with recumbent, moderately long,
white pile. Femora black, white pilose, tibite luteous yellow, their tip black ;

tarsi luteoas yellow at the base, black distally. Wings cinereous hyaline, the
.stigma brown, the veins of the disk narrowly cloiuled with brown ; fourth pos-
terior cell open.

Female. — Front narrow above, short black pilose across the middle, below which
there is a narrow white pollinose cross band ; no black hairs visible on the under
side of the head. Abdomen nearly bare, thickly grayish white pollinose, leaving
a large dark brown, semi-oval, basal cross band on the second segment and similar,
successively smaller ones, on the next two segments.

Hab. — California.

This species, with T. mehmophleba Loew, forms a connection with
the genus Tahuda. From Loew's species it will be distinguished by
the bare front in the male ; in the female by the abdominal markings,
and the absence of black abdominal pile.

CYRTIDJ5.

Acrocera litiij*ata n. sp.

ilfaZe.— Yellow; three broad, dorsal, thoracic stripes, pectus and tip of tarsi
black ; abdomen with irregular brown fasciae. Length 3 mm.

Vertical triangle and occiput black, the latter pollinose. Doi-sum of thorax
honey-yellow, the humeri and post-alar callosities yellowish white, in the middle
with a broad black stripe, attenuated behind, and on each side a large elongate
spot or stripe. Pleurse dark ; pectus black. Scutellum black above, the margin
broadly honey-yellow. Tegulse white. Abdomen yellow, translucent, the second
and third segments on the sides brown, connected by a basal fascia, narrower on
the third, dilated triangularly in the middle ; fourth .segment with a median,
basal, subtriangular or T-shaped spot. Venter brown in the middle. Legs ytllow-
ish white, the tip of all the tarsi and claws black. Wings hyaline, veins yellowish.

Hab. — Washington.

Latvia Kletii O. Sacken, Wheeler's Reports, vol. v, Zool. 804.

Two specimens of this beautiliil large Cyrtid from New Mexico
are easily recognizable. The species is almost entirely bare, the
sparse, short, black and light colored hairs on the dorsum of the
thorax are hardly discernible. In the South American species of
this genus, so far as I can learn, there is always a considerable vesti-
ture ; this fact, together with the termination of the second vein in
the first, renders its location in this genus a little doubtful. I can
see scarcely any golden reflections in my specimens, but, on the con-
trary, a pronounced blue or violet reflection, almost obscuring the
green of the abdomen of one. The stumps of vein on the anterior
branch of the third vein and near the tip of the fourth are wanting.

Ociiiva heluo O. Sacken, Western Dipt. 276.

I have a specimen of this species agreeing with the description,
except that the outer first posterior cell is but slightly coarctate, not
closed and petiolate.

NORTH AMERICAN DIPTERA. 295

Pterodontia iiiisella O. Sacken, Western Dipt. 277.

I have several specimens of this species from Washington varying
from six to nine millimetres in length. The black markings of the
abdomen vary in extent, and, from comparison with Eastern s})eci-
niens (P. flavipes Gray ?), I can find no constant difference, and be-
lieve them to be the same.

DOLICHOPID^.

Plagioneurus univittatus Loew, Wien. Ent. Monatschr. i, 43; Neue
Beitr. viii, 69; Monogr. ii, 196, pi. vi, fig. 36.

A single male specimen of this species from San Domingo agrees
well with the de.scriptions of the author. The genus was founded on
female .specimens, and hitherto the male — so important in the ge-
neric definitions of this family — has been unknown. The generic
characters apply very well, except that the face is a little less broad.
The author, however, was very much mistaken in supposing that
" the peculiarities of the female seem to indicate that the hypopygium
of the male is disengaged." In reality the sexual apparatus is almost
completely hidden.

PIPUNCULID^E.

Piptiiiculus opacus n. sp.

Female. — Black, abdomen narrowly gray fasciate; face white; legs chiefly
black; thorax with bristles; fourth longitudinal vein with a stump, cross-vein
near middle of discal cell, stigma small. Length 6 mm.

Front below and the face silvery white ; front elsewhere black, grayish polli-
nose. Antennae black, third joint large, reniform, silvery on the front and inner
side. Dorsum of thorax and scutellum black, apparently gray pollinose, with
black pile, and on the post-alar callosities and scutellum with black bristles.
Pleurffi pollinose. Abdomen depressed, opaque black, the posterior margin of
the segments narrowly, and the sides, gray pollinose; along the sides in front
with light yellow, behind with black pile. Legs black, femora gray pollinose ;
tip of femora, base and tip of tibise, and all the tarsi, yellowish red, the tip of the
last brown, with bristly hairs ; pulviili large, yellowish white. Front, and es-
pecially the middle, femora behind with white pile, hind femora and tibiie with-
out with fine bristly hairs. Wings nearly hyaline, stigma small, brown ; anterior
cross-vein near middle of discal cell, last section of fourth vein angulated and
with a stump.

One specimen, Washington Territory. The ]n-esence of bristles
and pile, the shape of the abdomen and the neuration, all are suffi-
cient to justify the erection of a new genus. F. auctas and modestm
seem to be related, European, species.

296 S. W. WILLISTON.

MUHCID^ CALYPTRAT.E

Hyalomyia aeiieoveiitris n. sp.

3Iale. — Black, abdomen metallic coppery bronze, margined with white pollen ;
wings broadly brown anteriorly near the middle; thoi-ax not vittate. Length
6 mm.

Front narrow below the ocelli, with a slender, opaque, black stripe, filling out
the front above, a little dilated below, the triangular frontal part lightly polli-
nose on the sides, clothed with black hair and bristles. Antennse black, the third
joint a little longer than broad. Face and cheeks white pollinose. Dorsum of
thorax black, but little shining, faintly pollinose, except, when seen obliquely
from behind, there appear an irregular white cross-band before the suture and
more or less silvery ])ollen in front of the scutellum ; clothed with black pile.
Abdomen broadly oval, depressed, shining dark metallic coppery bronze, less so
near the base ; the third, fourth and fifth segments, in well-preserved specimens,
conspicuously margined with snowy white pollen ; the short hair black, near the
tip with some fine bristles. Legs, black, pulvilli brown. Wings in the middle
broadly brown, the distal part, and behind the fifth vein, subhyaline, the base
brownish yellow.

Four specimens, Washington Territory. A female specimen with
these, that may possibly be the same, is larger, the third antennal
joint smaller, the eyes nearly contiguous below the ocelli, the abdo-
men less shining metallic, and the distal part wholly lightly pollinose,
except a narrow, median, indistinct stripe (Avhen viewed from behind
the pollen and stripe much more distinct). The wings differ very
distinctly in being hyaline, with the base and basal veins yellow.

This genus seems to be well represented on the Pacific coast. I
have three other species not well enough preserved for description.
One is larger (7 mm.) with broader front, red antennae, and with
considerable red on abdomen. The others are small (3 and 4 nun.)
and resemble the female mentioned above. The wings in all are
nearly hyaline.

Cistogaster «livisa Loew, Ceutur. iv, 78 ; Gymnosoma occidua Walker, List,
etc., iv, 692.

Walker's species seems only to be the female of Loew's male. It
differs very much from the male, as the females of this genus and of
Ghjvinosoma usually do ; I have taken them in numbers in Connec-
ticut. The head is white, only faintly yellowish on the sides of the
frontal stripe ; the dorsum of the thorax is shining black, with three
broad white pollinose strij^es ; the abdomen black, with a median pol-
linose stripe, and two pollinose cross-bands, the fourth segment chiefly
pollinose ; the first and second segments are rarely red on the sides.
The male sometimes has the black mai-kings of the abdomen much

less in extent or even wholly wanting, except the basal spot. Males
from Kansas, Colorado and California I cannot distinguish, though
the abdomen more frequently has less or no black.

Heinyda sp.

The type species of this genus, H. aurata R. Desvoidy, has been
recognized by Mr. V. v. Roeder (Berl. Ent. Zeitschr. xxv, 212)
among specimens from Missouri. I have a specimen from Washing-
ton Territory that may be the same. The genus is very distinct from
Ocyptera in the open first posterior cell, the very long third antennal
joint, and the thickened large hypopygium folded beneath the ab-
domen. My specimen has a very glossy silvery golden face, black
antenuc^, elongate-oval bright shining black frontal stripe, a broad
light yellow, translucent, interrupted band on the second abdominal
segment, much broader and complete on the venter, and a narrow,
interrupted, basal, dorsal band on the third. Legs yellow, the distal
half of hind femora, the four front femora in front, and all the tarsi
black. Length 9 mm. The genus Ancydogaster Bigot (Bull. Soc.
Ent. Fr. 1884, 95), seems to be closely allied.

Head whitish yellow, the ground color of the sides of the front black, but
nearly concealed beneath yellowish pollen ; frontal stripe ochraceous or reddish.
Antennae brown or black, the second joint and base of third on the inner side
more or less yellowish. Proboscis black, palpi yellow, projecting a third or a half
beyond the oral margin. Thorax black ; the humeri, sides, and posterior part of
the dorsum obscure yellow, dorsum rather thinly yellowish grayish dusted, when
seen from behind more thickly so, and with three slender stripes anteriorly.
Scutellum somewhat obscure yellow, with strong spines. Abdomen reddish yel-
low, the distal part more or less broadly testaceous ; with stout black spines, the
sides broadly bare in front, in the middle occupying the whole length of the seg-
ment, but not in the shape of a shallow V. Legs black ; tibiae yellowish or
brownish red, front tarsal joints of the female only a little dilated. Wings as

Hystricia soror n. sp.

Female. — BhicK scutellum dark red, palpi yellow ; second joint of the antennaj
short, third long and broad, convex in front. Length 10 mm.

Eyes densely lutescent pilose. Front with two rows of bristles, the inner one
extending only a little ways on the face. Occiput with black hair and white
pile. Face thickly covered with light gray pollen, less thick on the sides of the
front. Antennfe black, first two joints as in H. abruptn, the third about four
times as long as the second, reaching nearly to the bottom of the face, broad,
convex in front. Thorax light grayish pollinose, the dorsum with the beginning
of slender stripes in front; scutellum, except the base, deep red, thickly beset
with spines. Abdomen deep black, shining, wholly and densely beset, except
the first segment, with stout black spines; venter in the middle thickly clothed
with similar spines. Legs black, the tibise, faintly reddish ; distal front tarsal
joints disciform. Wings nearly hyaline.

One specimen, Arizona. I would have identified this with the
South American H. mgriventris Macquart (Dipt. Exot. ii, 3, 44, pi.

Juriiiia algens Wiedemann, Auss. Zw. ii, 285, 8 (Tachina).

An examination of a considerable number of specimens that may
be included under this species discloses differences perhaps specific.
I give them briefly.

«,. % . — Epistoma moderately projecting, palpi slender, antennte black, third
joint two-thirds as long as the secoiid, rounded on the angles below and moder-
ately dilated ; front broad.

Three specimens, North Park, Colorado. This is certainly dis-
tinct, and probably is J. ait Ida v. d. Wulp. (Notes from the Ley den
Museum, iv, 82).

In numerous females from most of these localities the palpi seem
to be uniformly more, the third antennal joint less dilated. The
front tarsal joints are considerably dilated ; in the male these joints
are angular. In the females from North Park, Colorado, the third
antennal joint is truncate, angular, but less dilated than in the males ;
the aristal joints are likewise elongate, and the epistoma more promi-
nent.

Desvoidy, Myod. 35,

Specimens that I identify as this are all larger than the size given
l)y Wiedemann, reaching a length of as many as seventeen millime-
tres. In the material I have I distinguish three forms or species, as
follows :

a. % . — Front with a single row of bristles on each side reaching below the
base of the antennae. (A few smaller bristles without below, and within above,
in both sexes, are not considered as forming a distinct row.) Third joint of the
antennae a little longer than the second ; palpi yellow.

9 .—Front with a single row of bristles extending below the base of antennae,
and exteriorly with two strong anteriorly directed ones. Front tarsal joints very
much dilated.

Hab. — Connecticut, New York, Florida, Colorado, New Mexico.
The antennre vary much in color and the third joint appears to be
usually smaller in the female.

h. % . — Front much narrower, antennae black, the thii'd joint smaller, not lon-
ger than the second, palpi more blackish.

One specimen. North Carolina.

c. 9-^Like the females of a, but the front tarsal joints not dilated. The
claws, pulvilli and bristles of the front are as in the other females.

One s])ecimen, Connecticut.

This specimen would seem to be related to the genus Mikia Kowarz,
and must resemble M. magnifica Mik. The second joint of the an-
tennse is, however, more slender.

All the above mentioned specimens agree in having a row of stout
spines on the posterior borders of the second and third abdominal
segments.

300 S. W. WILLISTON.

Jiiriiiia (Fabricia) hystricoides n. sp.

/^ ^ .—Like J. hystrix {a), but the third anteniial joint comparatively larger
and longer, the second abdominal segment with only two median posterior spines
and the front tarsal joints of the female not dilated. Length 14-17 mm.

The third joint of the antennse is about twice as long as the second, the frontal
stripe is broader and more noticeable, the epistoma less projecting than in /.
hystrix, and the abdomen does not have the thickened and rigid spines charac-
teristic of that species, but has more slender and less numerous ones ; where, in
hystrix, the second segment has a row of ten to fifteen stout spines in the middle
behind, the present species has but two smaller ones, and only about twelve in
the hind border of the third. Most especially, however, does the female differ
in not having the front tarsal joints at all dilated. The species or form that I
have called c under hystrix occupies a singular middle position between the two
in this respect.

Hab. — Connecticut, District of Columbia, Virginia, Georgia, New
Mexico, Arizona.

A specimen from California is more deeply black, the antennae
lighter, the abdomen with a bluish reflection.

Jurinia lateralis Macquart, Dipt. Exot. ii, 3, 42, 8, pi. iii, fig 10.

Ten male specimens from New Mexico agree very well with the
description of this species.

Jurinia siuaragdina Macquart, Dipt. Exot. ii, S, 39, 2, pi. iii, fig. 6 ; ? J.

amethystina, ibid. 42, 9, pi. iii, fig. 7.

'^ 9 .— Tegulai nearly white; third joint of the autenuse longer than the sec-
ond, convex in front; thorax dusted, deep greenish blue-black; abdomen deep
shining black with greenish reflections; second and third segments without
median anterior bristles. Length 12-15 mm.

Antennfe red, third joint a half longer than the second, strongly convex in
front, largely black. Dorsum of thorax with a distinct greenish bluish reflec-
tion, when seen from behind rather thickly poUinose and with two distinct
slender stripes in front. The alidomen deep shining, but the green or blue re-
flection or color not so evident.

This species is given by Macquart with the habitat " Bresil ?" but
his descrii)tion applies so fairly well that the name may be provi-
sionally accepted for our species. The length of the antennal joints
prevents the acceptance of J. amythystina Macquart, and the color
of the tegulae of J. vlrginiensis Macquart.

Jurinia apicifera Walker, List, etc., iv, 718.

/^ 9.— Second joint of antennte reddish yellow, but little shorter than the
anteriorly convex third. Thorax shining brassy, but partly concealed beneath
yellowish pollen. Abdomen shining metallescent black ; no anterior median
bristles on the second and third segments; extreme tip and hypopygium fre-
quently red. Legs black ; front female tarsi moderately dilated ; front femora
poUinose behind. Wings lightly brownish, yellowish at the base. Tegulse nearly
white. Length 12-14 mm.

Very common, Massachusetts, Connecticut, New Hampshire,

This seems to be Walker's species, but it is very probable that it
has been described under other names. Specimens from San Domingo
I cannot distinguish ; the dorsum of the thorax seems a little less
metallic.
Jurinia decisa Walker, List, etc., iv, 715.

Specimens that I identify as this I have from New Hampshire,
Connecticut, Virginia, Colorado and New Mexico. The antennae
vary in coloration. The small, but conspicuous, brown spot on the
anterior cross vein, dark tegulae, and the third joint of the antennae
being broader near the end, with the deep red abdomen, will render
this species recognizable.

A number of specimens from the White Mountains agree suffi-

of frontal bristles, however, reaches " tot even onder den sprietwortel."
In the male the third antenual joint is larger, as long as the second,
the abdomen red on the sides, and the fourth segment frequently in
large part black. The front tarsi of the female are dilated. A
female from Washington does not seem to differ,

also has the abdomen marked similarly.

terior borders, and a broad median stripe reaching to tip of abdomen, black ;
second, third, and fourth segments broadly fasciate with grayish pollen ; tibiae
chiefly dark reddish. Length 10-12 mm.

Female. — Third joint of antennae smaller; first abdominal segment at the base,
second segment at the middle and a spot exteriorly behind, third segment with
a broad posterior band, fourth with a median stripe, black ; front tarsal joints
dilated.

Gyiniiochseta alcedo Loew, C'entur. viii, 61.

I refer a female specimen from Connecticut to this species, though
I hardly understand what is meant by the " tomentum" of the face
and humeri. There are minute spinules on the costa, otherwise the
description applies well. A male from Wyoming seems to be the
same ; the palpi, however, are blacker, and there are distinct spinules
at the tip of the auxiliaiy vein.

Ciiyiniiocliieta vivida n. sp.

Female. — Sides of the frout with a doulile row of bristles below. Antennte and
palpi black. Second and third abdominal segments each with three pairs of
median bristles. Length 13 mm.

Bright metallic green, with violaceous reflections. Face and the posterior
orbits below with a gray satiny lustre ; lower part of the face and the cheeks in
ground-color red; occiput, posterior part of the checks, and the sides of the
front, shining. Front with an opaque dark reddish-brown stripe, moderately
broadened in front, pollinose when seen obliquely; hair of the occiput black and
yellow. Antennse black, third joint a half longer than the second. Orbits
above with two strong bristles, directed forward. Thorax scarcely dusted on the
humeri and sides. Tegulse white. Legs black, femora greenish. Wings cine-
reous hyaline; a stump of a vein on first posterior cell ; co.sta with two spinules
at tip of auxiliary vein, the last section of the fourth vein more oblique than in
G. alcedo.

Gjimioeha'ta ruflcoriiis n. sp.

Female.— Xntennte wholly light red, the third joint broader and proportionally
a little longer; palpi reddish yellow; frontal stripe broadened in frout ; a single

Male and female specimens from San Domingo, Arizona and Cali-
fornia I refer to this species, differing from bifasciata in the antennae
being shorter, with the third joint not more than twice the length of
the second, the posterior margin of the third segment more broadly
black, and the last section of the fourth vein more concave. Mac-
quart (1. c.) united the species, prematurely I think, as the difference
in the antennas is not sexual, as he supposed. I have males and
females of each, agreeing in the antennal character, or at least not
appreciablv diffei'ent. The difference in length is considerable, and
I can hardly think it an individual variation ; in any event numerous
specimens are needed to make it clear that such is the case. The
size of the pulvilli and ungues will distinguish the sexes.

Belvoisia v. cl. Wiilpi n. sp.

Female. — Black, face silvery on the sides; dorsum of thorax before the suture
opaque, shining behind, the last two segments of the abdomen deep opaque
orange-red, antennae and legs black, wings bvown. Length 14 mm.

In size and structure like B. bifasciata. Sides of the face silvery white, in the
middle between the ridges opaque black. Front opaque black, the middle stripe
ashy ; on each side with two rows of bristles. Antennae wholly black, the third
joint about twice the length of the second. Palpi black, the tip cinereous. Dor-
sura of thorax to the suture, or a little beyond, deep opaque black, behind bright
shining. Scutellum subopaque. First two segments of the abdomen deep black,
moderately shining, the third and fourth wholly deep opaque orange or brick red.
Tegulfe dark brown. Legs black ; front femora behind with a row of rather
slender bristles, the middle and hind tibise with stout spinous bristles without.

The front is narrower above than in B. bifasciata, the bristles of
the front are stronger ; there are but two on the hind margin of the
first and second abdominal segments ; the claws are small, as usual
in the females. The wings are lighter colored in the anal angle and
posterior border.

MEIjAXOPHRYS gen. uov. [TacMninarum.)

Head in profile nearly square. Front long, gently inclined, broad
in the female, about one-third of the width of the head in the male ;
in the male with a single row of not very strong bristles reaching to
but not below, the base of the antennae. Face in profile very gently
retreating, nearly vertical and straight, deeply excavated, and with
sharp, smooth, free and bare lateral ridges ; sides of face broad in
the side view, wholly bare. Oral opening elongate ; palpi slender,
proboscis not elongate. Cheek nearly horizontal, gently convex
below, broad, bare ; fringed along the lower border with a row of
fine bristles, not perceptibly stouter, or longer in front and not as-
cending on the side ridges ; epistoma but very little projecting. An-
tennae elongate, the third joint in the male four or five times as long
as the second, in the female shorter ; arista thickened, not elongate.
Eyes rather small, elliptical, thinly pilose in the male (I do not dis-
tinguish any hairs in the female). Occiput convex. Abdomen
short, broad, convex, bristles not abundant nor strong. Front tarsal
joints of female slightly dilated. Neuration as in Echinomyia ; pos-

IVIelaiiophry!^ flavipeniiis u. sp.

% 9 . — Deep blue-black, shining ; a silvery stripe between the eyes and base of
the anteunsB ; wings light yellow at base ; tegulse. yellow. Length 12-13 mm.

Cheeks and face bare, smooth, shining black ; from the eye above, on each side,
a horizontal yellowish silvery stripe runs to the base of the antennse. Front less
shining, in the middle with an opaque, lightly furrowed stripe. Antennse black,
arista luteous. Palpi luteous. Occiput with thin black pile. In the male, beside
the black bristles, the dorsum of the thorax is clothed with moderately long thin
black pile ; in the female with short recumbent black hair. Abdomen in the
male with short, erect, abundant black pile, wanting in the female ; two weak
bristles on the hind margin of the second segment, a row on the hind margin of
the third and fourth segments. Legs black, bristles not very stout. Wings
brownish yellowish, at the base light reddish yellow ; tegulse yellow.

Five specimens, Wyoming, California. In the California female
the veins of the wings exteriorly are clouded with brown. The
specimens from Wyoming I took in 1878 in the vicinity of Como.
The sj)ecies in general appearance resembles Jurinia algens, but the
remarkably projecting face is very different from any Tachinid known
to me.
lUicroplithalina nigra Macquart, Dipt. Exot. ii, .3, 85, 1, pi. x, fig. 2.

This species, the type of the genus, I have recognized in a specimen
from Pennsylvania, but Macquart's specimens must have been in poor
preservation. The face, cheeks and front are densely covered with
pollen, that on the sides of the front ochraceous, the median frontal
stripe is dark reddish brown. The ground color of the face and
cheeks is, as stated by Macquart, deep red. The dorsum of the thorax
and scutellum is thickly covered with brownish gray pollen, leaving
four slender black stripes, the outer ones abbreviated and interrupted.
The female front is broader than that of the female, and has, besides
the single row of bristles of the male, two strong bristles without
above. My male specimen, from Western Kansas, may be different.
It has the ground color of the head lighter, the antennae wholly red,
the wings less brown, and the posterior cross- vein not /like, but with
a strong median outward convexity.

Since writing the above, I have examined a number of specimens
of this species from New England. Rather oddly, however, they
were all greasy and uniformly black, apparently like Macquart's
type. By soaking them in ether, however, they have been restored
to nearly their original- condition. They have the abdominal seg-
ments broadly banded in front with white pollen. The European
species referred to this genus, by Egger, seems to be closely allied,
the legs being perhaps lighter colored, and the abdomen differently
marked.

NORTH AMERICAN DIPTERA. 307

9Iorinia sp.

I have species of this genus agreeing closely in their generic char-
acters with European specimens.

Plirissopocia prseceps Wiedemaim.

I have specimens of this very large Sarcophagid, agreeing well
with Wiedemann's description, from San Domingo.

Hypodernia liiieata Villers, etc.

I have specimens of this species from Northern California and
Arizona.

<£<leinagena tarandi Liune, etc.

I can confirm the statements of the occurrence of this species in
America. I have seen specimens from Alaska. Richardson (Fauna
Boreali) speaks of the occurrence of a bot-fly in great numbers in the
American Arctic regions ; it is probably this.

Oclitliera mantis Degeer.

I am unable to distinguish Californian and Eastern specimens of
this common species.

Oclithera exsculpta Loew.

I have specimens of this Cuban species from the Southern States.

Spilographa electa Say.

Mr. Pergande has sent me specimens of this species bearing the
label " Bred from berries of Sokmum Carolina, Oct. 7, 1877." They
were from Missouri.

Cepltalia ruflpes Meigen. Syst. Beschr. v, 291, 1, pi. xlvii, fig. 15 ; Schiner,
Fauna Austr. ii, 176.

Specimens from Virginia, collected by Mr. Pergande in June,
agree so closely with the description of this European species, that I
believe the species the same. The legs and front are dark, the hind
femora and tibiae almost wholly black. The fly is very singularly
ant-like in appearance.

Catalogue of the Described Species of South
American SYRFHID^EI.

BY PROF. S. W. AVILLISTON.

A catalogue of the South American species of Diptera is very
much to be desired. One was begun, in an excellent way, recently
by Lynch, but, unfortunately its progress has been interrupted, and
its plan only comprised the Southern fauna. There is a vast deal of
Avork yet to be done before any real list of the South American spe-
cies is possible, for many synonyms will have to be cleared up, and
most of the early described species must be recognized, — a no incon-
siderable task — and redistributed in the modern genera ; neverthe-
less, a preliminary catalogue will give us a sketch of the fauna, —
an indispensable one — from which many lines must be rubbed out
and many more filled in before the picture becomes at all complete.
As a contribution towards this end, I offer the following list of the
South American Species of Syrphidae. Little can be done in such
a work save compile, but I have spared no pains to render the com-
pilation complete, and have made such distributions as a careful
perusal of the descriptions and a tolerably full knowledge of the
North American forms have suggested. It should be distinctly un-
derstood, however, that such distributions and remarks as I offer have
only, in general, a negative value.

About three hundred names have been given to the South Amer-
ican species, distributed among about forty genera. About the same
number of species are actually known to occur in the United States,
located under nearly sixty genera, so that one may safely say that
less than half of the actual fauna of South America in this family
is yet known.

But little can be ventured on the general facies of the fauna based
on descriptions alone, yet I would direct attention to some points of
interest that have impressed me from a perusal of the literature.
The Volucella, Eridalis and Microdon groups appear to be unusually
predominant. Undoubtedly many of the names are synonyms, still,
enough must remain to indicate a proportionally far greater abun-
dance of these forms than exists North of Mexico, though their

NORTH AMERICAN DIPTERA. 309

Southern character is well indicated in our fauna. Helophihis, which
with us is distinctly a Northern type, is poorly represented. Species
and genera with club-shaped abdomen are unusually numerous, and
are undoubtedly mostly very active in their habits. Forms con-
spicuous for their absence are the larger, bright-colored, less active
species. I find no certain indication of a single species of Milesia,
Spilomyia, or Temnostoma, having been hitherto described. The typical
American genus Mesograpta is very rich in species, apparently, while
Syrphus, in the narrow sense, I do not believe will be found as well
represented as in North America. Nor do there seem to be any
species of Chilosia now known. Owing to the greater diversity of
])hysical conditions, it is very probable that a far richer and more
varied fauna will be eventually disclosed, and one more divergent
from the European, than is our own. The genera Pia, Bhoga, Sal-
jjingogaMer, Meromacrus, Ortholophus, StUbosoma, 3Iacrometopia, Ster-
phus, and the less differentiated Phalacromyia and Glaurotricha, are,
so far, peculiar to the region South of the United States.

Walker's species will be found in a list by themselves at the close.
Generic names with him afford evidence so unreliable of the real
affinities of the insects, that it is safest to consider the generic limits
as commensurate with those of the family.

I desire to express my hearty thanks to Mr. George B. Cresson,
Custodian of the American Entomological Society, for very kind
assistance in the preparation of this paper.

* Mr. Bigot suppresses (1. c.) both Lycastrirhyncha Big. and Lycastris Walk, as
not being sufficiently distinct from Rhingia ; at the same time he retains his own
genus in his synoptic table of the genera of Syrphidfe (Ann. Soc. Ent. Fr. 1883,
230-258) under the group with closed marginal cell, where, indeed, his original
diagnosis of the genus would bring it. Macquart describes R. nigra as having
" nervures normales" ; if he was correct, R. nigra and L. nitens must be distinct,
both specifically and, probably, generically.

t For dichotomous tables of the known species of Phalacromyia and Volucella,

AFRICAN LEPIDOPTERA. 325

Contributions to a Knowledgo of the LEPIDOPTERA
of West Africa.

BY REV. W. J. HOLLAND, M.A., PH.D.
PAPEE I.

I propose in a series of papers to present the results of the study
of a large body of interesting material received by me during recent
years from the Western Coast of Afi-ica, for much of which I am
indebted to my friend, the Rev. A. C. Good, whose many excellences,
both as a Christian minister and as an enthusiastic observer of nature,
are forthshadowed by his patronymic. In the following pages I
present descriptions of three species of diurnal Lepidoptera which
I believe to be new to science ; and I also present descriptions of
the females of three species hitherto only known in the male sex.
In all cases figures are given, and if I have been inadvertently led
into creating synonyms, those of larger knowledge than myself will
quickly detect the fact by means of the plates. In that event I shall
be happy to have my error pointed out to me.

The males of this genus, of which but two species are as yet known,
are i-emarkable for the large patch of dark hair-like scales near the
costal margin of the posterior wings. With the exception of the

* The generic name given by Doubleday in the " Genera of Diurnal Lepidoptera"
is undoubtedly more felicitous than that bestowed by Hiibner, being in a measure
descriptive, yet the name given by Hiibner has the priority, and is set aside by
Doubleday without assigning a reason so far as I have observed. Nevertheless,
inasmuch as Trimen and Butler both accept the name given by Doubleday I
hesitate, at least for the present, to restore that of Hiibner.

genus Terinos, which is East Indian, there is no other genus included
in the Nymphalince propei-, whicli presents a like phenomenon. On
the other hand the males of many genera included in the Satyrince
are furnished with patches and tufts of long hair-like scales. These
a])pendages are doubtless sexual.

Fp:male. — Topical forrn.^ Wings somewhat broader, and less
acute at the apex, than in the male. A small caruncula or ridge
upon upper surface of posteriors at the end of the cell. This is
found in all females, never in males. The basal area of the upper
surface of both primaries and secondaries is dark fulvous, the outer
half of the wings light fulvous, the division between the darker and
lighter areas being marked by an irregularly waved and toothed
line of dark fuscous, heaviest upon the costal margin of the })rima-
ries. The end of the cell of the primaries is also indicated by a line
of fuscous. The purplish iridescence discernible in certain lights
upon the wings of the male is lacking in the female. A row of six
sagittate black spots, one for each intra-neural space extends across
the primaries about one-fourth of the distance from the margin.
This band of sagittate marks is continued on the secondaries parallel

* Mr. Doubleday at the time of the publication of the " Genera of Diurnal
Lepidoptera" did not know the female, though acquainted with the male by nu-
merous examples. Mr. A. G. Butler tells us in his "Catalogue of the Fabrician
Diurnal Lepidoptera" that the types of both the male and the female of this
species " agreeing in the fulvous ground-color of the wings" are contained in the
British Museum as part of the Banksian Collection, and calls attention to a white
form of the female from Gaboon " which mimics Harma Althea." Mr. Trimen
in the "Transactions of the Ent. Soc. of London," vol. xxvii, p. 328, incidentally
alludes to " the butterfly which the late Mr. Hewitson referred (I believe rightly)
to the female sex of lole, which I noted as 'fuscous; all the outer area of the
wings dull white, with the spots and streaks strongly and blackly marked ; mark-
ings of the under surface agreeing with those of lole % '." These are the only
references I find to the female of this interesting species after an exhaustive
search of the entire literature of the subject, and I have been, therefore, embold-
ened to give a full description of the two forms of the female, of which several
examples have come into my possession.

to the outer margin, gradually passing toward the anal angle into a
continuous zigzag line. This series of sagittate spots and lines are
followed on both primaries and secondaries by a submarginal line of
black, acutely angulated at the middle of each intra-neural space,
and this is succeeded on both wings by a marginal line also of black.
Between these two lines the ground color appears as a series of ful-
vous lunules. Near the apex of the secondaries, in the region cov-
ered in the male by the oval patch of dark leaden-hued, hair-like
scales, characteristic of the genus, are three heavy, oval, black spots,
of which the one in the middle is the lai-gest, and the first is fused
at the costal margin with the row of sagittate spots already described.
Two similar, but smaller spots, are found, one near the anal angle
and the other in the preceding intra-neural space. Fringe dark
brown. The under surface is much lighter than the upper, and alto-
gether lacking the purplish iridescence of the males. The markings
are as above, but very faint, excej^t in the case of the last of the band
of sagittate spots on the primaries, w'hich is heavy and black, and
the oval spots of the secondaries, which reappear on the under sur-
face as black ocelli, pupilled with white and surrounded by an ochra-
ceous ring. On their inner margin these ocelli are bounded by silvery
spots resembling those found in the genus Argyimis. One female ;
expanse 2] inches.

Ogove River, W. Africa.

Dimorphic Female. — The dark fulvous of the basal area of the
upper surface of the wings of the typical female is replaced in this
form by dark fuscous, having an olivaceous tint, and shading into
black near the middle of the wings. The light fulvous of the outer
half of the Avings of the typical female is replaced by white, having
a lilacine lustre. The spots and lines are as in the typical form, but
broader and running together. The apices of both anterior and pos-
terior wings are also more or less clouded with fuscous, somewhat
obscuring the markings. The under surface is lilacine gray and
white, with the markings as in the typical form, but more distinct.
Head, thorax and abdomen concolorous. Four females; exp. 2> in.

primaries. Both wings crossed near the base and at the middle by
three bands of dark red margined by black. Of these bands the one
near the middle is the widest. Both wings crossed beyond the middle
by a band of broad hinules, compressed and fused at the nervules, of
a light fawn color, with dark sagittate marks in the centre and sur-
rounded by dark brown outer shades. These markings grow grad-
ually darker from the costa of the anterior wings toward the anal
angle of the posteriors. The cell in both anterior and posterior
wings crossed near the middle and at the end by geminate black
lines, the spaces between which are light rufous. Anterior wings
with a marginal line of black ; posterior with geminate submarginal
lines, the interspace being rufous brown. A white, subapical spot
on primaries. Fringe white. Under surface as the upper, but the
marginal area much lighter, save at apex, and the spots and lines
broader and heavier though less sharply defined, and more preva-
lently rufous than on the upper side. Palpi, thorax and abdomen
concolorous. Expanse of wings 2| inches.

Described from one imperfect 9 in coll. Holland, from Ogove

ever, as intense as in the male. Apex and outer margin of the
primaries deep brown or black. Three black spots just beyond the
cell of primaries unite to form a dark transverse shade, or fascia,
extending from the costa half way across the wing toward the inner
angle. The space between this shade and the dark shading of the
apex is much lighter, but broken by the nervules. which are shaded
on either side by black, and by a black subapical spot situated be-
tween the fifth subcostal and the discoidal nervule. Posterior wings

Under surface bright orange, shaded with darker orange. Anterior
wings with three somewhat sagittate, black spots beyond the cell,
and a faint brown shade between the first and second median ner-
vules, and a large oval black spot between the fifth subcostal and the
discoidal nervule. Above this oval spot two minute light blue spots,
jHipilled with dark blue. A series of light blue lunules shaded in-
wardly with black extend from the apex, where they are widest,
along the outer margin as far as the second discoidal nervule ; margin
black ; fringe white. Posterior wings crossed near the middle of the
cell by tw^o irregular bands of very dark purjjle or blue-black, the
innermost bordered on the side of the base, and the outermost bor-
dered on both sides by light ultramarine blue. The middle of the
marginal area traversed by a row of seven oval spots of bright ul-
tramarine pupilled with dark blue-black, these spots diminishing in
size from the middle towards the costal and anal mai-gins. A sub-
marginal line of black, followed by a line of light blue ; outer mar-
gin black ; inner margin broadly blue, dusted with black scales ;
fringe white ; upper surface of palpi, head, thorax and abdomen of
same general color as upper surface of wing ; under surface of palpi
and abdomen bluish white ; antennae dai'k fulvous. Expanse of
wings 2} inches.

Described from one female in coll. Holland, from Ogove River,

Cramer, Donovan, and Butler have figured the male of this- ex-
quisite species, but the female, which is somewhat less brilliant than
the male, has never hitherto been described or figured.

with costal and outer margins shaded with dark brown, passing at
apex of primaries into black. Primaries with a small, annular, black
mark at base of cell, in the middle of the cell a figure "8" mark,
and at the end of the cell three black lines, the innermost of which
is narrow and fiiint, and the two outermost heavy and irregular fusing

together at extremities and forming a crescent. Beyond these lines is
a series of irregular dark shades, produced along the nervules, and bor-
dei-ed externally by light fulvous ; these are followed by a series of sub-
apical dark marks and a submarginal row of dark spots, of which the
three nearest the apex are the darkest. Secondaries with two annular
marks in cell, the uppermost the largest, and an elongated, oval mark
at end of cell. Internal margin clothed with long brown hairs ; anal
groove pale straw-color. Head and thorax olive-brown, abdomen
rufous. Underside of primaries at apex and on cell lilacine white.
The remainder of the primaries broadly rufous brown, lighter toward
inner angle. The spots and lines in the cell and the submarginal
row of dark spots as upon the upper surface. A row of narrow
white lunules, bordered on the side of the base with black, begins at
the middle of the space between the second discoidal and the first
median nervule, and runs to the posterior margin, nearly parallel to
the costal margin. The ground color of the underside of the secon-
daries is on the basal area lilacine white, on the outer half of the
wing light stone gray Avith a reddish tint. Anterior margin broadly
black, shading near base and outer angle into maroon. This broad
band is broken about half way from the base by a nearly white
spot having the form of an inverted comma. A broad, but very ir-
regular raaroon-black band originating at the point marked by this
comma-like spot, and fusing with the broad band on the anterior
margin crosses the wing transversely at the middle and terminates
just before reaching the posterior margin. The broad, white, disco-
cellular space enclosed between these dark bands is marked by three
very dark spots, the two uppermost of which are more or less con-
fluent with the dark band of the anterior margin. Underside of
palpi, breast and abdomen, white. Alar expanse 2t inches.

Described from one imperfect male in coll. Holland, from Ogove
River, W. Africa.

I dedicate this fine species to my good friend, Mr. Good, its captor.

Genus CHARAXES. Ochsenheimer.

Male. — Anterior wings well rounded on costa, subfalcate at apex,
deeply excavated on outer margin opposite cell, rectangular at inner
angle. Posterior wings well rounded on outer margin, regularly
toothed at extremities of nervules, but ivithont tails. The ground

AFRICAN LEPIDOPTERA. 331

color of the pi'iiiiarie.s and ?;ecoiidai'ies is rich rufous, deepest at base.
The primaries have a bhick spot in the middle of the cell, and a
large black crescent at the end of the cell, two oval and somewhat
confluent subapical black spots, one near the origin of the first me-
dian, and the other near the origin of the second median nervule.
A broad black band irregularly toothed inwardly, and regularly
toothed externally extends from the apex to the posterior margin.
This is followed by a row of bright red lunules gradually increasing
in size from the apex to the posterior margin, and these are followed
by a marginal band of dark fuscous. The broad black band of the
primaries is continued upon the secondaries, and is at first quite nar-
row upon the costal margin, but rapidly widening and sweeping
toward the base and the anal angle, covers almost the entire basal
two-thirds of the wing, except an oval spot of light red on the costal
margin above the cell. The outer third is bright red embellished by
a submarginal band of ocelliforin black spots pupilled with dark red.
Of these spots the two at the anal angle are very small the four in the
middle large and heavy, and confluent at the nervules, and the two
nearest the outer angle small and lighter in color. The underside of
primaries and secondaries is much lighter than the upper side and have
a bright purplish sheen over the entire surface. Three small bluish
white spots mark the apex of the primaries, a narrow band of dark ru-
fous extends from the apex across both wings vanishing before reaching
the anal angle of the secondaries. A small dark brown spot appears
near the basal extremity of the cell in the primaries, and is followed
by a mark of the same color resembling the figure " 2 ". A dai'k
oval blotch margined with very dark brown appears at the end of
the cell, and is followed by two dark oval spots between the cell and
the apex near the costa. There are three oval spots margined with
dark brown between the median nervules near their origin. The
posterior wings are traversed by two very irregular and broken bands
of narrow brown lines, one crossing the middle of the cell, and the
other its outer extremity. A submarginal row of minute, bluish
white spots takes the place of the row of heavy ocellated spots
which appears on the upper side. The color of the upper and under
surfiice of the body harmonizes with the tint of the adjacent wing
surfaces.

In certain lights the upper surface of this beautiful insect, which
in coloration bears a superficial resemblance to Charaxes Lucretia

Africa.

Charaxes Talagugte n. si>. pl. viii, fig. 3, %, .

Mai>e. — The outline of the wings is similar to that of C. Ephijra
Godt., % . The upper surface of primaries and secondaries is dark
velvety black with a greenish reflection. A macular band of white
extends beyond the middle across both wings gradually widening
from near the apex of the primaries, where the spots composing it
are mere narrow streaklets, to the inner margin of the anal groove
of the secondaries, where it abi'uptly terminates. This white band
is margined on its exterior iu the primaries, and on both sides in the
secondaries by a bluish green shade. The ground color of the under
surface of both wings is a lavender gray. Both wings are traversed
as on the upper surface by the white macular band. The other
markings are as follows : a small oblong black spot at base of cell in
the ^j/'/>/iflrie.s, two small round spots arranged vertically n])on middle
of cell, followed by a narrow and obtusely angled black line, and a
curved line at end of cell. Two narrow vertical lines, one above,
the other below the third median nervule near its origin ; three nar-
row, vertical black lines bounding the inner margin of so much of
the white macular band as lies between the median nervules, a broad
geminate black shade near the inner angle of the ])rimarie6. Two
narrow black lines cross the cell of the secoiuhries, the outermost
being produced upwards to the costal margin. A submarginal band
of faint olive-green .lunules bordered on both sides by narrow black
lines crosses the secondaries, which are also adorned by a marginal
series of small black points edged inwardly with pale blue. The
upper surface of the palpi, head, thorax and abdomen are black.
Four minute white spots ornament the head, and two each of the
patagia. The underside of the palpi and the breast are snowy white.
The sides of the thorax beneath and the legs of the same gray color
as the adjacent parts of the wings, the underside of the abdomen is
yellowish white.

The Pulilication Committee reported in fUvor of publishing paper
193, entitled:

Studies on the North American Chalcididse with descriptions of
new species from Florida, by William H. Ashmead.

The same Committee placed on the table the concluding i)art of
vol. xii of the Transactions of the American Entomological Society
and Proceedings of the Entomological Section of the Academy of
Natural Sciences and reported that ninety-six pages with seven plates
of vol. xiii had been completed.

Mr. Cresson reported that the Hymenoptera which had been placed
in the hands of Mr. W. H. Patton for study in 1879, had been re-
turned. The condition of Mr. Patton's health was such that he
might not possibly recover ; in the mean time the entii'e cabinet of
Ml-. Patton was placed in the Society's care. The collection contains
much valuable material.

MONTHLY PROCEEDINGS.

MR. CHARLES ^VILT.

In 1859 a few friends met to cojisider the formation of an entomo-
logical society, and in response to the call Mr. Wilt was one of fifteen
who assembled. The organization was soon completed, and Mr. Wilt
became treasurer March 14th of that year, remaining in that position
until the close of 1863.

For neai'ly a year the Society met at the houses of its members
until it was resolved that a library and cabinet would be necessary
to aid the members in their studies. The difficulty of finding a home
for the Society was solved by Mr. Wilt, who placed at its disposal
the large saloon-room of his house, then recently l>uilt, and from
Jan. 9, 1860, until August, 1862, these comfortable quarters were
occupied without expense to the Society, and in this room the first
volume of our Proceedings ^vas printed — on a small hand-])ress —
page by page.

The interest taken hy Mr. Wilt in the Society increased with its
progress, and no one was more ready to respond to any call for per-
sonal or pecuniary assistance than he. While not an active student
of entomology he kept himself well advised in whatever related to
its progress, especially in the fauna of our country. His interest
was concentrated in the two orders Coleoptera and Lepidoptera,
and by liberal purchases and constant exchanges he accunuilated a
collection of the former order standing high in rank in our country,
while in certain portions of the Lepidoptera, the SphingidcU and
Catocalae, his series has but few, if any, superiors.

His cabinet was at all times freely at the disposal of others, and
verv many of his friends were accustomed to use it in naming their
local captures. To those who desired the use of his material for
more thorough study he was especially kind in loan and gift, as it
has been my pleasure on many occasions to testif\\

Of the life of Mr. Wilt apart from his connection with our Society
very little need be said. With an early training to mercantile pur-
suits he continued in business until his death, ac(|uiring a competency,
which enabled him to indulge his love for entomology.

Mr. Charles Wilt was born June 12, 1821, and died April 3, 1886.

Notes on the " Biologia Centrali-Americaiia."

BY OEO. H. HORN, M. D.

Students of the natural history of the North American continent
have niucli to be thankful foi' in the progress of the im])ortant work
undertaken under the editorship of Messrs. Godman and Salvin, with
the collaboration of those whose names scarcely need any. additional
lustre from the " Biologia."

The work aims to embrace that portion of the continent of North
America south of the boundary line of the United States and in-
cluding the Isthmus of Panama. From a political stand-point the
Peninsula of California should have been included, but it has been
(emitted, from the fact that many of the species have been described
by Dr. LeConte and myself, showing that the fauna of that region
(with the exception of the extreme southern end) is much more
closely related to our Arizona region than would be any similar
.southern extension from the boundary line of Arizona.

The territory along the boundary line is for the most part an in-
hospitable region — hot, dry and barren, with occasional more or less
fertile valleys extending in a general direction N. W. to S. E. Some
of these valleys are pi'operly Arizonian extensions, others extend
u})wards from Mexico. The latter case prevails in the northwestern
portion of Mexico, while the reverse exists in the northeast, in the
region west of the Rio Grande. This results in a preponderance of
the species of the region from which the fertile peninsula arises. The
broad belt of desert, hot and rainless, east and southeast of Fort
Yuma seems to act as an effectual barrier against the intermingling
of the species of the two faunas to any notable extent.

The collection made by Morrison teaches very little. How far he
went below the boundary I do not know, although my series was
purchased as from Arizona purely, and the same series is quoted by
the authors of the " Biologia" as from northern Sonora. With very
few exceptions the series was such as we are accustomed to meet in
Arizona with no greater admixture of Mexican forms than we find
on the Texas side of the Rio Grande.

Vlll MONTHLY PROCEEDINGS.

On the whole the two tauiias, Boreal and Central America, seem
to be quite distinctly marked, more so than would be expected from
the topoo;raphy of the greater part of the border zone as there are
no natural obstructions — as high mountains or wide seas — in the way
of a free intermingling of species.

These remarks, which must be restricted in their application to the
Coleoptera alone, express the views entertained by Dr. LeConte and
explained in his notes on the first series of Coleoptera collected by
Xantus in the Peninsula of California. Mr. H. W. Bates seems to
have adopted what is practically the same idea, as I have gathered
from his introduction to vol. i, and isolated expressions more particu-
larly in the Appendix.

To students of the Coleopterous fauna of the more northern por-
tions of the continent the work is indispensable, and will doubtless
diminish in future the duplication of descriptions of species on the
two sides of the line. It is only to be regretted that the authors
have satisfied themselves with cataloguing very many of the species,
giving, often, too abundant citations of habitat in place of a fcAV lines
of description, which would have been of far greater utility.

The first volume of Coleoptera deals with the Cicindelidse and
Carabidae, and is from the hands of Mr. H. W. Bates. It contains
316 pages and 13 plates, on which are figures of 323 species and
varieties. Publication of the volume began in October, 1881, and
finished in August, 1884. In going over the pages a few notes have
been made, which have been thought of sufficient interest to give :

Iresia boucardi Chev., p. 17. A male of this species taken at Cor-
dova by Jose Nieto, and now in my possession, is entirely rufo-testa-
ceous beneath. The male was unknown to Mr. Bates, and it is prob-
able that he is entirely correct in separating Iresia pulchra as distinct.

Calosoma peregriuator Guer. As this species has C. carbonafum
Lee. for a synonym, the remarks concerning prominem and hujubre
Lee, should be disregarded.

Micrixys distinctus Lee. This species should be added on p. 41.
I have seen a specimen in the possession of Mr. Flohr, collected (I
think in Coahuila) in Mexican territory.

Dicaelus flohri Bates, p. 49. Mr. Bates is correct in referring
(on p. 269) this species to lcevipen7iis Lee.

A second species, D. costatm Lee, occurs in Mexico (see preceding
note).

ENTOMOLOGICAL SECTION. IX

On p. 73 ]Mr. Bates seems to have doubts as to the position of
Polpochila. The difficuhy seems capable of sohition by accepting
as groups (or whatever else they may be called) those aggregations
of genera with male tarsi dilated and (1) biseriately squamose, or
(2) spongy pubescent, and (3) those with undilated male tarsi with
few or no squamules. While it is inferentially stated here that I
have suggested too many subdivisions I am reminded on p. 75 that
I have not made quite enough.

Evarthrus constrictus Bates, p. 80. This name is preoccupied in
the genus and in the series with bisetose labial palpi.

Blechrus glabratus DufU., p. 192. This Eurojiean species is quoted
from California. That the nigrinus Mann., is a Blechrus is undoubted,
as LeConte had a type from Mannerheim. It is highly probable that
the nigrinus is glabratus. I am not aware that Metabletus occui's in
California, but it is known from British Columbia, etc.

On p. 220 Mr. Bates intimates that I consider Loxopeza majiiscula
Chd., a synonym of L. grandis Hentz (not Hald.). All my publica-
tions have been quite to the contrary.

The Diseoderus mentioned on j). 27(3, as number 10, had been de-
scribed by me as rohustus.

With page 256 of this volume the supplementary part begins, in
which we find introduced the species collected by Mr. Morrison. On
going over these latter it will be observed that, with extremely few
exceptions, all had been described from our territory.

It seems worthy of sjiecial note that Scaphinotus mexicanus is the
only Cychride described or recorded, while in California species of
the subgenus Brennus are numerous. Arizona has not, to my
knowledge, furnished even a specimen of Cychride, while the adjacent
region of NeAV Mexico furnishes Scaphinotm Snmvii Lee, and north-
ward in Colorado we find only S. elevatus.

The occurrence of a species of Carabus is remarkable. In Calo-
soma the fauna of Mexico is unexpectedly less rich than our own,
twenty being enumerated from Mexico and twenty-six with us.
Three are common to the two regions: scrutator, Sayi (armatum Lap.)
and peregrinator (carbonatum Lee.) while another, angulatum, is ad-
mitted to our lists with doubt.

MONTHLY PEOC. ENT. SEC. A. N. S. (2) JUNE, 1886.

X MONTHLY PROCEEDINGS.

The fifth vokiine of Coleoptera c(jiiiprises the Cerainbycidas and
Bruchidse (the intermediate volumes being in preparation), and con-
sists of 537 pages and 26 phates, ilkistrating over 500 species or va-
rieties. The part relating to Cerand)ycida} is the result of the studies
of Mr. H. W. Bates, that concerning the Bruchidae of Dr. David
Sharp.

Perilasius Bates, j). 16. This genus is related to Brothylm and
O&tnidus. It differs from the former in having the anterior coxse less
angulated externally ; the antennae are similarly sulcate. Omddm
has the anterior coxse as in Ferilasim, but the antennae are not sul-
cate. P. championi has a great superficial resemblance to 0. guttatvs
Lee.

Page 84. Mr. Bates proposes to unite under the generic name
Sphenothecvs those species which, in our fauna, are divided among
several genera, viz. : Sphenothecus, Isclmoaiemis, Entomosterna and
possibly Perarthrm. As we have but one species in each it would be
presuming to controvert the opinion of Mr. Bates, but the separation
of genera in the Cerambycidae seems to depend entirely on the stand-
point from which separation starts. Important structural characters
have, in this family, at times merely specific or sexual value, as be-
tween Gaurotes eyanipeiiuis and abdomhni/l.t in the mesosternum as
well as in the vestiture of the hind tarsi in the two sexes of Acviceop)^
militaris. The form of the mandibles, the initial point of LeConte's
subdivision, seems to me more important and less subject to variation
than the form of the mesosternum.

Lepturges infilatus Bates, very closely resembles our avr/uhitm, but
is less distinctly punctured.

L. symmetrimacula Bates, is extremely close to our symvietricus.
I have seen but one of the form.

On page 216 Mr. Bates recurs to the question of Am])hi()nycha
and its type, and I think supplies what was lacking in my previous
notes in proof of the fact that LeConte was the first who described
the genus and gave a definite type. Mr. Bates' argument is correct
if we admit the propriety of shifting one of Chevrolat's names from
one type to another, and then admitting that Leseleuc established
the genus, although " he did not give a generic formula."

On page 314 the name Agalissus gratus Hald., has been placed us
a synonym of clytoides, while the case should be reversed.

ENTOMOLOGICAL SECTION. XI

Myi'MoIamia Bates, j). .'^Bo. This is identical with Cyrtinus, as I
am informed by Mr. Bates. It is interesting to find the genus ex-
tending so far as Panama.

On page 392 it is suggested that our species of Liopus, — Wilt'd,
crassulus and fascicidaris should be referred to Eleothinus. Tlie char-
acters seem extremely feeble for generic separation.

With page 437 of the fifth volume the portion relating to the
Bruchidse begins, Dr. David Sharp the author. In the Mexican
fauna there are but three genera, as in our own, but the species far
exceed those described in our fauna. Dr. Sharp remarks that in
our " Classification" the Bruchidte are placed between the Chryso-
melidte and Tenebrionidee. While this is true it is merely from the
mechanical necessities of book-making. The Teuebrionidte and
Chrysomelidae belong to tw'o distinct divisions of normal Coleoptera,
and while the Bruchidse are placed between the two families, it is
intended to indicate their relationship with Chrysomelidse, but not
even the most vague with the Heteromera, as will be seen by reference
to p. xxxvi of the Classification.

Bruchus longiventris Shp., p. 476, is protractus Horn.

Spermophagus p. 492. Under this genus Dr. Sharp has suppressed
Zabrotes Horn, and pnjbably justly, but whatever the typical form
of Spermophagus may be the species robinue. and those separated
by me as Zabrotes should not belong to the same genus.

Notes from tlie Miisenin at Caiubridge.

BY GEORGE H. HORN, M. D.

The Museum became the recipient of the cabinets of Ziegler and
Melsheimer by purchase, and the types have been examined with
extremely few exceptions by Mr. Henshaw and myself, and our re-
sults will soon be jniblished by hira in the manner already adopted
for other of the older authors. The search for the actual types re-
(juired a considerable expenditure of time and labor, as many were
scattered in the general collections of the Museum, while others were
in the cabinet of Dr. LeConte.

XU MONTHLY PPvOCF:EDINGS.

Fortuuately, a short time before my arrival, the Museum had re-
ceived a number of duplicates representing a portion of the species
studied by H. W. Bates in the volumes on Carabidae and Ceram-
bycidse of the Biologia Centrali-Americana. These fortunately re-
mained intact until I had an oj)portunity to examine them. I have
made the following notes :

Lachnophorus sculptifrons Bates. I am unable to see that this
differs from L. elegantulus Mann.

Anchonoderus myops Reiclie. My A. quadrinotatm resembles this
species, but has a much larger humeral red spot. Unfortunately I
had not sufficient material for comparison, but I suspect that the
species have been unduly increased.

Anchomenus decempunctatus Reiche. I am not able to see that
this differs from our Platynus bembidioides Kby., which in our fauna
extends from the Hudson's Bay region to Arizona.

Philophuga viridicollis. This species has been incorrectly deter-
mined, and should be amoena Lee. Chaudoir has already made the
same mistake, calling the latter species Horni. I have already cor-
rected this error. Trans. Am. Ent. Soc. 1882, p. 144.

Galerita mexicana Chd. It is highly probable that the sj^ecies
described by me as G. decipieiis (Trans. Am. Ent. Soc. xii, p. 131)
is identical with this, my determination being from memory alone,
but why Mr. Bates makes atripes Lee, a synonym I cannot under-
stand, as it is certainly not warranted either by the facts of the case
or the date of publication.

Anisotarsus mexicanus DeJ., has been described as Ankodaeiylm
arizoMB Casey. I can see no reason why the generic name used by
Casey should not stand.

Anisotarsus brevicollis Chaud., also occurs in Arizona. It is a
very black species, the female more opaque than the male.

Bradycellus obsoletus Say. This species does not differ from the
very variable TachyceUm nitidus Dej.

Chlaenius caeruleicollis Chd., has been redescribed by me as C.
insperatus.

Chlsenius chrysopleurus Chaud., has been incorrectly determined
by me as C. validiis (Trans. Am. Ent. Soc. 1876, p. 257).

Bembidium scintillans Bates, has been redescribed by ]\Ir. Casey
as B. vinnulmn.

Stenosphenus hirsutipennis Bates, is identical with S. lugens Lee.
Nyssodrys contempta Bates, is Haldemani Lee.

ENTOMOLOGICAL SECTION. XIU

At the time of my review of the Acanthocinini there was but the
typical specimen known, a S . 8ince, others have been abundantly
obtained by Mr. G. Noble, of Savannah, and the presence of an ovi-
positor in the 9 shows that it must he referred to the group Acan-
thocini and placed after Acanthocinus, from which it may be sepa-
rated in the table by the antennjie not fimbriate and the lateral
tubercle of the thorax close to the base. The species must be known
as Nyssodrys Haldemani.

Malacopterus lineatus Guer., with the species M. vlttatm Lee, is
identical.

Tetraopes rubrocinereus Thorns., is identical with T. discoideus Lee.

The following synonymy was given me by Mr. F. Blanchard from
Mr. A. Fauvel :

Stenus atomarim Casey, is pumilio Er.
mavimops Casey, is humilis Er.
suhgriseus Casey, is morio Grav.
reconditus Casey, is tarsalis Ljimgh.

The following additional notes have been made from an examina-
tion of specimens in the cabinet of Dr. LeConte :

Bembidium stabile Lee. This species is exactly identical with
lugubre Lee.

B. nitens Lee. (pidpes X Mann.) does not differ from Grapii Gyll.

B. plctum Lee. This name being preoccupied, flavopictum 3Iofs.
must be used.

Pterostichus (Poecilus) cyaneus iee. This name is also preoccu-
pied, and Chaudoir has proposed cyanicolor, Abeille, 1875, p. 84.

Gyrinus gibber Lee. This specimen is simply a deformity of
analis. By an accident this species is erroneously placed in the
synopsis by Dr. LeConte, and should have come after analis, as will
be seen by the letter b, the mesosternum being not at all trilobed in
front as in pectoralis {vide Proc Acad. 1868, p. 370).

Elmis vulnercdus Lee, is merely a color variety of glaber Horn.

Pristoscelis cruralis Lee., should be i^eferred to Listrus.

Platycerus Agassii Lee. The type specimen is a female, and the
species described as P. ealifornieus Casey, is perfectly identical.

Leptura spuria Jjee. This is positively the % of Acmaeops mili-
taris Lee. In this species the first joint of the % hind tarsus is not
densely pubescent beneath.

Leptura quadrata Ijee. This species is a color variety of eonvcva,
itself a race of instabiHs. L. quadrata has pale antennae and legs,

Xiv MONTHLY PROCEEDINGS.

hut this is by no nieauri rare in noi'iually marked specimens of con-
vexa ; the elytra are entirely black, except tw(j marginal yellow spots
on each elytron, one a little before, the other behind the middle ;
these are the ends of the yellow bands seen in convexa.

Leptura brevicornis Lee. This sj)ecies was described from a female.
At the present time b(jth sexes are before me. In the female the
antennae are short, gradually thicker to tip, extend but little beyond
the humeri and are 11-jointed, while in the male the antenna are as
long as the body, slender and subserrate (as in Ganmle^isis) and with
the eleventh joint almost divided. The male insect is also much
smaller than the female, the elyti'a more densely but less coarsely
punctured.

Leptura sexmaculata Linn.. The species mentioned by Dr. Le-
Conte in his table (New Species, 1872) agrees well with the figure
given by Olivier, but vexatrix Mann., is erroneously placed as a
synonym. The latter species more closely resembles conve.va in its
markings, but is a much more slender species, with tlTe apices of the
elytra obliquely truncate. L. vexatrix Mann., should be restored
to a place in our lists following sexmaculata.

Haltica inaerata Lee, is simply a color variety of ignita III.

The following synonymy has been otherwise observed :

Metachroma cuprea Provancher, Nat. Canad. x, p. 383, is Scelo-
donta nebulosa Lee. Through the kindness of I'Abbe Provancher
I have been enabled to examine the type.

Brumus septentrionis Weise, Stett. Zeit. 1885, p. '40^, is Exocho-
nms marginipennis Lee, and the variety in which the elytra are in
great part red, the suture black and abruptly dilated at apex, on
each elytron two black spots.

In the Revue d'Entomologie, 1885, p. 134, Mr. Fauvel indicates
the possible identity of Direoxt fuma Lee. with Phkeotrya Vandoueri
Muls. I have recently received, through the kindness of Mr. Fauvel,
a specimen of the latter, and am happy in confirming his supposition
by direct comparison. The question of the generic name remains
to be settled. From the remarks of Mr. Fauvel it seems that Dirccea
Fab., is purely a synonym of Serropalpus and Phloeotrya was pro-
posed by Stephens for the species co;isidered by his cotemporaries as
Dircsea. As Mr. Fauvel is doubtless correct, the name Dircrea in
our lists should be replaced by Phlceotrya and the specific name
fusca Lee. by Vaudoueri 3fuls.

ENTOMOLOGICAL SECTION.

Daring the progress of the " Genera" Dr. LeConte, with a com-
mendable liberality, sent to Lacordaire for study a number of types
of genera, and in particular many from California, among which
were several uniques, namely, Acreph maculata, Craniotus jmbescens,
Oryptadius mflatus and Auckmobim subkevis. By an unfortunate
calamity the vessel conveying them never reached Euro])e, and the
specimens were lost ; the types of Schonherr's Curculionidac were
near meeting a similar fate some years later. Two of the lost species
were recovered dui'ing my travels in the West, the third is due to
Ci'otch, while it is now, after more than thirty years, a pleasure to
add the fourth.

Psoa {Acrep'is) luactllata Lee. Ann. Lye. v, p. 213. Form elongate, slightly
depressed cyliudrical, .sparsely pul)escent, aeneo-piceous varying to blue. Head
coarsely, moderately densely punctured ; thorax subquadrate, narrowed at base,
basal margin slightly reflexed, apical margin slightly impressed on each side of
the insertion of the head, median line slightly impressed posteriorly, disc coarsely
punctate, very den.sely at the sides ; elytra slightly wider than the thorax,
coarsely and deeply, but not densely punctured, surface variably ornamented
with yellowish white spaces forming often a narrow lateral and more irregular
median vitta. Body beneath seneous or bluish, the abdomen variable in color
sexually. Length .30-. 40 inch ; 7.5-10 mm.

Male. — Thorax a little longer than wide ; the three joints uf the antennal club
together much shorter than all the preceding joints. Abdomen above and be-
neath peneous, rarely paler at tip, the sixth segment distinctly emarginate.

Female. — Thorax broader than long ; the joints of the club nearly as long as
the preceding joints. Abdomen reddish yellow, the small terminal segment
piceous, the sixth segment not emarginate.

figure in each line is the typical form of the two species, and from
the series it will be observed that in imtculata the tendency is to
become vittate, while in the other the darker ground-color gradually
lessens, leaving the elytra simply red, spotted with blue.

In quadrmgnata the same sexual characters have been observed
as in macidata. In the former species the thorax is more nearly
ovate, the sides arcuately narrowing to base, while in maculata they
are parallel at middle, the disc more convex and shining, and less
densely punctured in the former species. The form of the two species
is also different, quadrisignata being more slender and cylindrical,
resembling Polycaon, while macukda more nearly approaches some
Clerides.

It seems remarkable that Dr. LeConte should have obtained an
unique of what seems the rarest species, and that more than thirty
years have passed without its recovery. In view of the great vari-
ability of the elytral markings of quadrisignata we were disposed to
suppress the name proposed by me as a possible variety, but I am
noAV confident that we have to deal with two distinct species.

I have been told that quadrisignata infests grape vines.
