VOLUME VI.

I.—A Catalogue of Rutherfurd’s Photographic Plates of the

Sun, the Moon, and the Stars.

BY JOHN K. REES.

Read March 9, 1891.

On November 13th, 1890, Lewis M. Rutherfurd, LL.D., of New

York City, presented to the Columbia College Observatory all his

photographic negatives taken between the years 1858 and 1878.

Many of the plates had been measured, and these measures were

included in the gift. The measures fill some thirty quarto volumes.

Several years ago (1884) Mr. Rutherfurd gave to the Observatory

his 13-inch equatorial with its photographic corrector, with which

the photographs, taken since 1868, were made; and at the same time

he donated to the Observatory his measuring engine supplied with

a glass scale. This improved measuring apparatus was used in

January, 1872, and subsequently.

The star cluster negatives received an exposure of either three or

Six minutes. Each negative bears the date, time of exposure, a

record of the barometer and thermometer readings, and other data

necessary for the reductions.

The Observatory of Columbia College hopes to,issue soon the

reductions of many of the measures.

Mr. Harold Jacoby aided in the preparation of the catalogue.

BY THOS. L. CASEY.

Read October 5, 1891.

The most important contribution presented in the following paper,

at least from a systematic standpoint, is a review of the Cistelide

of the United States, but I feel only too fully that the discussion

of the species of a local fauna, however complete and well intended

it may be, can count but scarcely more than as a letter in the alpha-

bet of a general monograph. In the absence of representatives from

other parts of the earth, we labor to a great extent blindly in the

delimitation of the higher groups, and in selecting proper structural

characters for the differentiation of the genera.

For various reasons, however, the accumulation of the necessary

material for a general revision of any family of Coleoptera, is now

an exceedingly difficult matter, and this difficulty is, with the present

system of museum management throughout the world, a constantly

increasing one. Whether or not we are to have any more epoch-

making monographs, is becoming largely a question for the museums

to decide, for it is here that material is principally accumulating.

These reflections cal] to mind another feature of the case, in which

this restrictive policy of the museums is to a great degree embar-

rassing, and which concerns us on this side of the Atlantic more

particularly—lI refer to the American types of Mannerheim, Maklin,

Hschscholtz, and Motschulsky. These are now reposing in extreme

security within some almost inaccessible European museums, where

they are practically never disturbed, but if transferred to an Ameri-

can museum where they could at least be occasionally examined by

our working entomologists, it would be a vast aid to us and would

be a loss scarcely at all appreciable to them. I go so far as to say

that all satisfactory study on our part in certain directions is com-

pletely checked, because of the absence of these types; from an

equitable and reasonably liberal point of view they should be placed

in our keeping, for the descriptions to which they answer are in

general quite insufficient, and are often worse than useless from

inaccuracy of statement.

After this short and I trust pardonable digression, it only remains

to be said, that the present opportunity has been taken to publish

the descriptions of some other more or less interesting species,

mainly in the Longicornia and Heteromera.

New York, August 18, 1891.

Note.

In a report of the proceedings of the Second Ornithological Congress (Nature,

No. 1129, p. 153), it is stated that among other resolutions favorably passed

upon was the ‘‘adoption of names, even faulty in construction or misspelt,

with all the consequences.’’ The phrase ‘‘with all the consequences’’ affords a

convenient pretext for the further discussion of certain matters concerning

nomenclature, which I have previously touched upon to some extent.

The designation of every species consists of two distinct parts: the generic

symbol and the specific name. The former need not necessarily have any

meaning whatever, the latter always must have a meaning; we should there-

fore apply to these two parts rules which are somewhat different.

I apply the word ‘‘ symbol’’ to the generic designation, because the latter is

not a word in the ordinary sense of being a combination of letters possessing

linguistic meaning, but is simply a codrdination of letters, the sole conditions

of which are that of being readily pronounceable, or consisting of consonants

and vowels harmoniously arranged, and of having a Latin termination, in order

to determine generic endings in the specific name. Even this last condition

has not been strictly complied with, as a great many generic symbols have

Greek or barbarian terminations, often necessitating the arbitrary determina-

tion of gender; nevertheless, words with endings which are neither Latin nor

Greek, such as Marail Less. and Lemming Cuv., should not be admitted. The

earliest printed symbol satisfying these conditions should be the one adopted.

The specific designation is, however, a word taken from the Latin, or from

any other language through the Latin by universal agreement, in order to

avoid the undue favoring of any of the languages at present in use, and the

inevitable discordances of opinion which would result therefrom. As one of

the prime conditions of the specific name is that it shall have a meaning, and

must therefore be linguistic in form and origin, there can be no objection to

the alteration of the printed word to suit the proper rules of orthography or

gender, when the intentions of the imposer of the name are evident. There

are, in fact, on the ground of uniformity and simplicity, many reasons why

this should be done, and why rules should be laid down and followed for

writing specific names derived from various sources.

Coleopterological Notices, IT. 31

Now let us ask the question: Upon what foundation principle does the

permanence and inflexibility of our nomenclature depend ’—for no scientific

notation or symbolization in any branch of human investigation can be of

value, which is not put beyond the power of individual opinion to alter at

pleasure. This question seems to be easily answerable if (1) we agree to adopt

the earliest properly published combination of letters intended to represent any

particular genus, and (2) if we formulate invariable rules for writing specific

-names, but is apparently unanswerable under any other conditions. If a

writer be permitted to alter the original spelling of a generic symbol on the

ground of incorrect orthography, we at once dispel any hope of permanence in

nomenclature, and open the door to new argument and discussion which may

result in a subsequent author giving a third designation, based upon his own

conception of the hypothetical intentions of the original namer, and so on

without end to the ultimate destruction of all semblance of stability: for there

are differences of opinion as to the proper spelling of certain words in all

languages.

If it be asked why the generic symbol need have no meaning in any lan-

guage which has ever existed, while the specific designation is required to

have a meaning in or through the Latin, it may be answered that it simply

results from the condition of nomenclature as we find it to-day. One need

but glancé over a small portion of the great Munich Catalogue, to see that the

proportion of generic words of unknown or dubious etymology, is so great as

to give character to the whole, and to necessitate the rule that generic words

must simply be considered harmonious combinations. In regard to the specific

names, however, we can perceive at once that the proportion of words among

them which are devoid of meaning or withdrawn from the influence of linguistic

rules, is not large enough to have any weight at all.

- In view of these facts, it is quite incomprehensible how the original generic

symbols Brentus, Sitona, Monochamus, Leiopus, Leichenum and a host of

others, could have been changed as they have been. Are not the words noted

harmonious combinations, and, as such, are they not as much entitled to stand

as Brenthus, Sitones, Monohammus, Liopus, and Lichenum? We must go

back to the original mode of spelling generic names before nomenclature can

be placed upon an absolutely stable foundation. The next catalogue similar

in scope to the Munich Catalogue, will be the first suitable opportunity for

effecting this change, and it is hoped that the liberties in spelling which have

been proposed in the one alluded to, and which constitute its only serious

blemish, will not be repeated.

Other questions involving more or less difference of opinion occasionally

arise, as for instance whether generic names, differing only in termination by

reason of gender or derivation, as for example Oplocephala and Oplocephalus,

Platycerus and Platyceras, or Tylas and Tylos, should be maintained as dis-

tinct. As the words become shorter such differences of ending constitute a

great part of the entire symbol. Ulus, for example, is quite a different word

from Ula, Ixus from Ixa, Janus from Jana, and numerous such resemblances

exist at present, but if we admit that Ulus and Ula are satisfactory as generic

12 Coleopterological Notices, ITI.

symbols, and there can be but little doubt that they are, we must also admit

Oplocephala and Oplocephalus; we should have absolute and consistent

law throughout. I believe the difficulty can be overcome if we hold that

generic symbols are not words in any sense, but constants, analogous to the

constants of a mathematical formula; that they form part of no language,—

although Latin by induction, and that they are completely indeclinable,

except when used in the genitive as specific names or in the nominative

plural as group names. Under these circumstances Ulus and Ula would be

distinct and different combinations of letters, and could be maintained as

genera with perfect propriety.

The Ornithological Congress has passed favorably upon the trinomial nomen-

clature. In regard to this it need only be said that the admission is a dan-

gerous one, for it will result finally in names including four, five or even six

words, and nomenclature will gradually become involved in a web of its own

weaving. If the trinomial nomenclature is admitted, it should only be with

the understanding that either the specific or subspecific name be bracketed.

Our system should remain essentially binomial.

CUCUJIDA.

LYCTUS Fab.

The characters given by me (Ann. N. Y. Acad. Sci., V, p. 324),

to distinguish the two genera Lyctus and Trogoxylon, I find to be

of no value, for, while applicable to the latter as represented by

parallelopipedus, the distance separating the anterior coxe gradu-

ally diminishes through calzfornicus and punctatus to the slight

prosternal width characterizing cavicollis and others. So also in

regard to the external prominence of the anterior tibie at apex, not

at all discernable in curtulus and a little more pronounced in paral-

lelopipedus, it becomes normally prominent in punctatus, this char-

acter not having the value here which it has in Eurymetopon. The

elytral punctures are completely devoid of serial arrangement in

parallelopipedus, have a slight tendency thereto in punctatus, and

are distinctly seriate in californicus. There are the same grada-

tions in regard to the prominence of the apical angles of the pro-

thorax. /

I am forced therefore to regard 'Trogoxylon as a synonym of

Lyctus, and, a few new forms having been recently received, the

pvesent opportunity is taken to give a complete statement of our

species as far as known :—

habitus, and means nothing more, the two affinities being about

equally pronounced.

L. caroline n. sp.—Parallel, moderately slender, rather convex, ferru-

ginous, the head and prothorax darker than the elytra; integuments shining,

the vestiture rather inconspicuous, yellowish. Head rather coarsely, moder-

ately densely punctate; antenne slender, one-half longer than the head, the

South Carolina. Mr. Morrison.

A single specimen. This species is easily distinguishable from

striatus, which it perhaps most closely resembles, by its entirely

different elytral punctuation and thoracic structure.

L. californicus n. sp. (Crotch MS.).—Rather slender, parallel, some-

what strongly depressed, castaneous to piceous-black, strongly shining; pubes-

cence not conspicuous. Head transverse, somewhat coarsely and densely but

shallowly punctured, the epistomal suture deep, transverse, the epistoma

short, almost impunctate, polished; eyes rather small, convex; antenne

slender, compact, almost glabrous, one-half longer than the head, the elub

small and slender. JProthorax as long as wide, feebly narrowed from apex to

base, the apex broadly, strongly arcuate, the base subtruneate ; sides straight,

minutely denticulate throughout; apical angles right, not rounded, basal

slightly obtuse, minutely denticuliform and prominent; disk feebly convex,

broadly, feebly impressed in the middle and finely canaliculate near the base,

coarsely punctate, the punctures not very dense, shallow, becoming fine and

sparse anteriorly especiaily toward the middle; pubescence coarse but sparse.

disk moderately convex, polished, rather finely, sparsely punctate, the punc-

tures deep but narrow and elongate, arranged in subeven single rows except

toward the suture and base, where they are confused, the intervals not

perceptibly punctate, the coarse sparse recumbent set entirely filling the

punctures and rather irregularly distributed. Abdomen polished, excessively

minutely and sparsely punctate. Anterior cox widely separated, the pro-

sternum polished and almost completely impunctate. Auterior tibie strongly

broadening toward apex, the apical angle acute and distinctly prolonged out-

wardly. Length 2.2-2.5 mm.; width 0.65 mm.

Coleopterological Notices, ITT. 15

California (Fort Yuma). Mr. H. F. Wickham.

One of the two specimens before me has the prothorax more

strongly narrowed behind than the type above described, the differ-

ence being probably sexual in nature. It will be observed that the

characters of this species are quite composite, the outer apical angle

of the anterior tibize being prolonged and acute, the elytral punc-

tures distinctly seria] in arrangement, and the anterior coxe widely

separated. It is the smallest of the genus known to me from our

territories.

L. curtulus n. sp.—Parallel, rather depressed, pale brownish-testaceous

throughout, moderately shining, the vestiture coarse, yellowish, moderately

long and dense and somewhat conspicuous. Head rather coarsely, very densely

punctate, the epistoma less densely so, the suture very deep, broadly arcuate ;

eyes moderate in size and prominence; antenne stout, nearly one-half longer

than the head, the third and fourth joints subequal and each rather distinctly

shorter than the fifth, club small but robust, oval and rather compact. Pro-

thorax as long as wide, distinctly narrowed from apex to base, the apex broadly,

strongly arcuate; base very feebly arcuate; sides straight; apical angles very

slightly obtuse, not rounded although slightly blunt, basal more broadly

obtuse and decidedly blunt; disk feebly convex, broadly feebly impressed in

the middle except toward apex, with a fine deep canaliculation near the base,

moderately coarsely, very densely punctate, a little more sparsely so near the

apical margin. Elytra two and one-half times longer than the prothorax and

scarcely at all wider than the latter, not distinctly more than twice as long as

wide, the apex broadly, abruptly and obtusely rounded; humeri right, not

rounded but a little blunt; sides straight; disk rather closely, confusedly

punctate, with two or three feebly defined, narrow, impunctate lines on each.

Abdomen polished, minutely and very sparsely punctate. Anterior coxe rather

widely separated, the prosternum polished and almost impunctate, the hypo-

mera rather finely and very densely so throughout. Anterior tibie gradually

much broader from base to apex but with the exterior angle not at all pro-

duced outwardly. Length 2.7 mm.; width 0.8 mm.

California.

The two or three narrow, slightly oblique, impunctate lines on

each elytron, is a character which is also sometimes observable in

paralleloptpedus and punctatus but much less distinctly. The

present species differs from californicus in its broader form, denser

punctuation especially of the hypomera and elytra, in its more nar-

rowly separated anterior cox, and in its uneverted exterior apical

angles of the anterior tibiz, as well as in its stouter antenne with

much larger club and in its slightly larger but less convex eyes.

L. punctatus Lec. from Cape San Lucas is a remarkably aberrant

species, broader and more convex in form than any of the others,

and with the elytra narrowed from apical third, more narrowly sub-

truncate and broadly arcuate at apex. The head is transverse, with

the eyes moderate in size and strongly convex, the antenne stout,

nearly normal in size and structure but with the clnb parallel, the -

epistomal suture very fine and scarcely perceptibly impressed. The

prothorax is much wider than long, nearly as wide as the elytra,

feebly narrowed from apex to base and with the sides feebly, evenly

arcuate throughout, the disk being feebly impressed in the middle

toward base. ‘The elvtra are not quite twice as long as wide,

very coarsely deeply and confusedly punctate, the punctures toward

base becoming dense and subcoalescent. The abdomen is polished,

minutely and sparsely punctate, the prosternum polished, rather

strongly but sparsely punctate, the process being rather broad

between the cox. The anterior tibize have the exterior apical

angle prolonged outwardly and acute. The head and pronotum —

are rather coarsely and densely and unusually deeply punctured,

and each puncture of the entire upper surface bears a short robust

erect seta, which is coarsely plumose or bushy in structure. The

feebly marked epistomal suture, parallel antennal club and peculiar

vestiture may perhaps warrant the generic isolation of this species,

in which event the name Trogoxylon Lec. could be appropriately

adopted for it.

ELATERIDA.

CHALCOLEPIDIUS Ksch.

The following species belongs near webbi Lec., but is much

larger :—

C. apacheanus n. sp.—Moderately slender and convex, smooth,

polished, intense black throughout, clothed rather densely with small robust

recumbent and squamiform hairs, which are strongly convex and finely

pointed, dark bluish in color, giving a deep violet-blue bloom to the surface,

the lateral edges of the pronotum rather broadly, and of the elytra very

narrowly, clothed with dense white recumbent pubescence, the white border

abruptly limited. Head strongly impressed, rather coarsely, deeply, sparsely

punctate, the interspaces very finely, densely punctate ; antenne short, two-

thirds as long as the prothorax, pruinose with violet-blue, the third joint but

slightly shorter than the fourth. Prothorax one-fifth longer than wide, in form

nearly as in webbi, very finely, moderately closely punctate throughout and

with scattered coarser punctures anteriorly, especially toward the sides.

Scutellum a little wider than long, polished. lytra in form and relation to

Coleopterological Notices, ITT. 17

the prothorax nearly as in webbi, polished, very minutely feebly and rather

sparsely punctured, with somewhat uneven, completely unimpressed series of

fine, rather distant punctures. Under surface polished, pruinose with violet-

blue toward the sides, minutely, feebly punctulate. Length 36.0-38.0 mm. ;

width 12.0-12.5 mm.

Arizona (Fort Apache).

This species differs from webbi, in addition to its very much larger

size, in the decidedly longer third antennal joint in the male, more

minutely punctulate surface with the pronotum coarsely punctate

anteriorly, in the strong impression of the head, in the abruptly

limited and much narrower marginal white vitte, and in the sparser

and deep violet-blue vestiture, the latter being extremely dense,

paler and olive-green in webbi. Together with webbi, it belongs

to Section III of Candeze, and in the vicinity of carcumductus, from

which it differs in its entirely flat and not alternately convex elytral

intervals.

SCARAB AID A.

POLYPHYLLA JHarris.

The western species which are homologues of decimlineata in

ornamentation, may be easily identified as follows :—

Antennal club of the male very large, fully three times as long as the stem;

vestiture more or less strongly squamiform.

Antennal club of the female nearly as long as the entire stem; ere in

lineata in its larger size, broader and more depressed form and

sparser vestiture, in addition to the characters given in the table.

Crinita seems to be comparatively limited in range, all the speci-

mens which I have seen being from Southern California. The

following is allied to crinita :—

P. diffracta n. sp.—Oval, strongly convex, piceous-black, polished, the

vestiture consisting of very narrow, extremely sparsely scattered scales inter-

mingled with longer erect hairs on the pronotum, the latter trivittate, each

elytron with a very narrow sutural and three discal vitte of denser white

seales, also a short humeral vitta which is more or less evanescent, but some-

times prolonged, the elytral vittz more or less disintegrated and uneven.

Head coarsely, densely punctate, the clypeus broadly reflexed, extremely

broadly, feebly bisinuate at apex and very densely clothed with yellow squa-

mose pubescence. Prothorax twice as wide as long, the apex broadly emargi-

nate and much narrower than the base; sides broadly subangulate; lateral

vitta interrupted anteriorly. lytra about three times as long as the protho-

rax, and, in the middle, one-third wider than the latter, rather finely, sparsely

punctate and subrugulose. Pygidium slightly wider than long, very densely

squamulo-pubescent except toward the sides, where it is very sparsely so, also

with asubdenuded median line. Length 21.0-24.0 mm.; width 10.3-11.3 mm.

New Mexico (probably near Las Vegas). | |

The two specimens before me are males; there is another in the

cabinet of Mr. Jiilich in which the elytral vitte are still more dis-

integrated. The antennal club of the male is still somewhat smaller

than in crinita.

Subvittata and hammondi of LeConte are easily distinguishable

from each other by the antennal character separating decimlineata

and crinita. The male club in subvitiata is fully three times as

long as the stem, and in hammondz but slightly more than twice as

long as the latter; there are differences also in the general character

of the elytral ornamentation, form of the clypeus, size and other

characters, showing that the two species are without doubt dis-

tinct. Mr. Dunn, who has taken both of them abundantly, states

that they are never found together.

THYCE Lec.

With increased care in collecting, the species of this interesting

genus are becoming somewhat numerous on the Pacific coast, where

they replace Lachnosterna to some extent. The species appear to

be more nocturnal than crepuscular in habit, and, although proba-

Coleopterologieal Notices, ITT. | Uy)

bly constituting a moderately large genus, are unquestionably much

less numerous than those of Lachnosterna.

The two following species have been received since my last refer-

ence to the genus :—

TN. Dlaisdelli n. sp.—Robust, moderately convex, form nearly as in

fossiger, rather shining, pale rufo-castaneous in color, the humeri and under

surface blackish ; vestiture pale ochreous in color.

Male.—Head, excluding the eyes, subquadrate, but slightly wider than

long, very densely clothed with short robust pubescence and long erect hairs ;

clypeus moderately refiexed, very feebly sinuate, the angles broadly rounded ;

antennz moderate, the club slender, straight, a little shorter than the stem ;

fourth joint of the maxillary palpi unusually robust, oval, twice as long as

wide, about three-fourths as long as the antennal club, the groove wide, deep,

extending from base to apex, two and one-half times as long as wide, the

bottom broadly, evenly concave and alutaceous in lustre. Prothorax two-thirds

wider than long, broadly lobed at base and subangulate at the sides, some-

what coarsely and densely punctate, clothed rather densely with robust

squamiform pubescence and fine, moderately long erect hairs. Scutellum

densely punctate and squamose. Flytra about one-third longer than wide

and nearly one-half wider than the prothorax, the apex broadly subtruncate ;

sides feebly arcuate ; humeral callus rather prominent; disk shining, moder-

ately densely and unevenly punctate and subrugulose, the punctures some-

what strong, the vestiture consisting of short recumbent moderately densely

placed hairs, which are robust but not at all squamiform. Pygidium finely,

densely punctate and clothed like the elytra. Addomen finely, densely punc-

tate and very densely squamulo-pubescent, the vestiture whiter than that of

the upper surface; sterna with the usual long silken pile. Legs rather

short, the posterior tarsi distinctly shorter than the tibia ; ungual teeth of the

corresponding tarsi very unequal, the anterior twice as long as the posterior.

Length 20.0-23.0 mm. ; width 9.4-11.0 mm.

California (Coronado, San Diego Co.). Dr. F. E. Blaisdell.

This species, which is represented by the male only, is somewhat

allied to fossiger, but differs in its more robust and less densely

placed elytral vestiture, shorter, much broader terminal joint of the

maxillary palpi and in its shorter posterior tarsi.

I have before me a female, pale brownish-rufous in color, strongly

shining throughout, with the elytral pubescence excessively fine

and sparse, much shorter and finer than in squamicollis, but about

twice as dense as in that species. It was taken at Los Angeles and

probably represents still another species which it would not be

advisable to describe in the absence of the male. It may possibly

be the female of the present species.

20 Coleopterological Notices, IIT.

T. squamosa n. sp.—Oblong-oval, strongly convex, piceous-black ;

integuments shining.

the base, the latter broadly subangulate ; sides broadly subangulate, the

margins strongly reflexed toward base, feebly serrate; apical angles narrowly

rounded, basal rather obtuse and broadly rounded; disk very strongly con-

vex, narrowly impressed along the middle, coarsely, densely punctate, clothed

which is dense along the median line except near the base. Scutellum densely

punctate and squamose. lytra one-third longer than wide, one-third wider

than the prothorax, subparallel; sides feebly arcuate ; humeri rounded ; apex

broadly subtruncate; disk finely, somewhat densely punctate and clothed

with distinct pointed scales. Pygidium slightly wider than long, convex,

minute recumbent hairs, sparsely placed, with erect hair as in the male.

Length 20.0-23.0 mm.; width 9.3-11.3 mm.

California (San Luis Obispo Co.).

A distinct species, somewhat related to harfordi, but easily dis-

tinguishable by many characters of both sexes. The tubercle of

the vertex is, throughout the genus, particularly characteristic of

the female.

CERAMBYCID &.

ERGATES Serv.

Subgen. TricHocnemis Lec.

The principal character upon which reliance was placed in sepa-

rating neomexicanus from spiculatus, is rendered somewhat doubt-

Coleopterological Notices, ITI. 21

ful from the fact that similar differences, in the male sexual charac-

ters at the apex of the abdomen, are observable in specimens appa-

rentlv taken in the same locality. I have observed them in examples

said to have been collected in Oregon, and forming part of the cabi-

net of Mr. Ulke, and Dr. Horn states (Tr. Am. Ent. Soc., XVIII,

p. 41) that they are equally visible in specimens in his own cabinet

taken in Vancouver Island.

Nevertheless there are some circumstances which lead me to

believe that this is not a case of ordinary fortuitous variation, the

chief of which is the apparent want of any known male specimen

in which the modification of the fifth segment is truly intermediate

between the forms figured on Plate IV, Vol. V, of these Annals.

Another singular fact is the remarkable disparity in general form

and several important structural characters, as exhibited in the

assumed male type of spzculatus—represented by a specimen in

my cabinet taken near the shores of Cour d’Aléne Lake, Idaho—

and the specimens taken by Mr. Meeske at Las Vegas, New Mexico.

Not being able, therefore, to be fully satisfied that the species

described by me as neomexicanus is actually the same as spiculatus,

it seems only right that the question should be held in abeyance

until more material can be collected in both of these, as well as in

other, localities. When this is done, and if it be then proved that

the two names are truly synonymous, I believe that it will be

demonstrated at the same time that the male of spiculatus is

dimorphous.'

PRIONUS Geoff.

The following species is allied to imbricornis :—

P. debilis n. sp.—Narrow, subparallel, rufo-testaceous, the elytra pale

brownish flavate, thin and almost coriaceous; lustre moderately shining.

1 Since this was written I have compared the females of the two forms in

question, and find that the mandibles of spiculatus are bidentate internally,

the teeth being situated before and behind the middle respectively, while in

neomexicanus there is but one tooth, situated at the middle; in the latter the

basal joint of the antenne is much shorter than in the former in both sexes,

but especially in the female. Having in mind the comparative constancy of

female structural characters, these observations tend to materially strengthen

my original position, in regarding. the two specimens of spiculatus and four of

neomexicanus which I have before me, as representative of two distinct but

rather closely allied species. Spiculatus inhabits the Pacific districts, extend-

ing inland toward the north and descending along the Rocky Mountains as

far as Colorado; to the southward of this limit it is replaced by neomexicanus.

22 Coleopterological Notices, IIT.

Head coarsely, deeply punctate, sparsely so behind ; eyes separated above by

three-fourths of their own width ; antenne (male) two-thirds as long as the

body, nearly as in imbricornis, 18-19 jointed. Prothorar more than twice as

wide as long, two-thirds wider than the head and three-fourths as wide as the

elytra; base and apex equal, transverse, each feebly sinuate laterally ; sides

parallel, feebly dentate at base and apex and also just before the middle;

disk rather finely and sparsely punctate. lytra twice as long as wide,

parallel, the sides feebly arcuate, obtusely rounded behind, narrowly dehis-

cent from basal third or fourth; inner apical angle obtuse, with scarcely an

indication of the everted tooth of embricornis; disk coarsely, deeply, subrugu-

losely punctate. Legs slender, posterior tarsi very slender, the under surface

densely pubescent only in two small spots at the apices of joints one to three.

Length 20.0-24.0 mm.; width 8.0-9.5 mm.

Indiana; Missouri; Kansas.

Represented by a very homogeneous series of seven male speci-

mens from the Levette cabinet; I have not seen the female.

This species is allied to ¢mbricornis, having nearly the same

antennal structure, but differs in its much smaller size, narrower,

more parallel and less convex form, less chitinized and paler elytra,

in the more widely separated eyes and in the vestiture of the hind

tarsi. In the normal forms of imbricornis—for there seems to be

at least one undescribed variety of this species before me—the eyes

are separated above by much less than one-half of their own width,

and the posterior tarsi are densely pubescent throughout joints one

to three, in a widely divided line except toward the base of the first

joint. The upper surface of the antenne is much more coarsely

and sparsely punctate throughout in debilis than in tmbricornis,

this being one of the most striking and constant of the differential

characters.

TETROPIUM Kirby.

The species before me may be recognized as follows—the char-

acters throughout being taken from the female, except when other-

wise mentioned :—

Elytra wider than the prothorax; third antennal joint in the male much

longer than the second.

Third antennal joint (female) pyriform, unusually short, scarcely twice as

long as wide; pronotum very pap oe except laterally; elytra

Pronotum with a narrow and abruptly limited median impunctate area

toward base, which is subcarinate; elytra generally pale.

parallelum

Pronotum without a median impunctate area except narrowly and vaguely

toward base; elytra usually concolorous.

Sides of the prothorax broadly rounded ; pygidium evenly parabolic.

schwarzianum

Sides of the prothorax vaguely subangulate in the middle, the punc-

tuation very fine, oe dense; pygidium triangular with the

apex narrowly Subtruncate ........00cceeceseessceecee . Vvelutinum

Elytra not wider than the Manca eed Seine fae of the male but

slightly shorter than the third, the latter equal in length to the fourth.

parvulum

The forms of Tetropium here mentioned seem certainly worthy

of recognition, and as far as can be perceived are as distinct as is

usually the case in the allied genera. The color of the elytra varies,

it is true, as is usual in this part of the Cerambicide, but the char-

acteristics of sculpture and structure upon which the species have

been separated, are of more permanent value. The genus will

probably prove to be more fully developed in our fauna than in the

European.

T. parallelum n. sp.—Elongate, moderately convex, parallel, piceous-

black, the elytra paler and uniform red-brown, rather dull throughout, the

pubescence short, very dense. Head densely punctate, the longitudinal fron-

tal groove feeble; antenne nearly one-half as long as the body, moderately

incrassate toward base. Jrothorax slightly wider than long, the apex and

base truncate, the former much the wider; sides broadly, obtusely angulate

at the middle; thence feebly convergent to the apex, more strongly so to the

base and almost straight; disk longitudinally, distinctly impressed in the

middle, finely, very densely punctate, extremely Gensely so laterally and

toward base except along a narrow tumid median line. Scutellum shining,

finely, rather densely punctate. Hlytra two and one-half times as long as

wide, about one-fourth wider than the prothorax, the apex obtusely and

abruptly rounded. Legs moderate in length, rather densely pubescent.

Pygidium triangular, with the apex SLIME uncate. Length 12.0-14.0 mm. ;

width 3.3-3.8 mm. 9°.

Colorado; New Mexico.

Represented by three females which agree perfectly among them-

selves. Parallelum slightly resembles cinnamopterum, but differs

in its larger size, more elongate elytra and in the characters given

in the table; it is more southern in habitat than cinnamopterum,

which is represented before me by both sexes from Canada and

24 Coleopterological Notices, ITT.

New Hampshire. In the male of cinnamopterum the pronotal

punctuation is still sparser than in the female.

T. schwarzianum un. sp.—Robust, the elytra somewhat depressed,

piceous-black and rather dull throughout, the pubescence short and dense.

Head moderately densely and somewhat unevenly punctate; antenne nearly

one-half as long as the body, the second joint nearly two-thirds as long as the

third, the latter feebly swollen toward apex. Prothorar but little wider than

long, the apex wider than the base, both truncate; sides broadly, strongly

arcuate, becoming convergent and straighter toward base and apex; disk con-

stricted just before the base, rather strongly, deeply punctured throughout,

the punctures generally separated by about twice their widths but denser

laterally and toward base, with a more or less narrow uneven impunctate

area toward base, which is not at all tumid. lytra not more than twice as

long as wide, in the middle nearly one-half wider than the prothorax, slightly

dehiscent near the apex and obtusely subtruncate; sides parallel and broadly

arcuate ; disk with indistinct traces of the usual two fine ridges. Legs mode-

rate in length. Length 14.0 mm.; width 4.5 mm.

Michigan (Marquette). Mr. Schwarz.

This species somewhat resembles velutinum, but differs in its

shorter and more robust form, more broadly rounded sides of the

prothorax and coarser, sparser pronotal punctuation. It is widely

different from cinnamopterum in all these characters, as well as in

its broader and more parabolic terminal dorsal segment, and much

longer antenne. The description is drawn from the female, and all

comparisons are made in the same sex.

T. parvulum 0. sp.—Parallel, depressed above, black, the antenna,

legs and elytra more or less pale; pronotum highly polished; elytra dull;

pubescence short, dense on the elytra. Head finely, sparsely punctate,

strongly tumid between the antenne and longitudinally, deeply sulcate ;

antenne two-thirds as long as the body, stout, gradually, finely attenuate,

the basal joint one-third longer than wide, second but very slightly shorter

than the third, obconical. Prothorax slightly wider than long, the apex

broadly sinuate in the middle, nearly one-half wider than the base, the latter

truncate; sides subangulate just before the middle; disk broadly impressed

along the middle, constricted just. before the base, smooth, highly polished,

finely, extremely sparsely punctate, the punctures larger and moderately

dense only on the flanks. Scutellum narrow, polished, with a few minute

widely distant punctures. L£lytra parallel, two and one-half times as long as

wide, broadly rounded at apex near which they are dehiscent, each elytron

rounded; sides straight; disk not wider than that of the prothorax, with

vague traces of the usual fine ridges. Legs short, the hind femora robust.

Length 8.0 mm.; width 2.2 mm.

Coleopterological Notices, ILI. 25

Indiana.

The description is taken from the male. The species resembles

cinnamopterum, but differs in many characters, chiefly mentioned

in the table, but also in its shorter and more robust legs. The

punctuation at the sides of the prothorax is coarser and sparser, and

the terminal joint of the antenne is quite different, being shorter

and without a well-marked cylindrical process at apex; the basal

joint, also, is much shorter, although this latter character is less

important.

HYLOTRUPES Serv.

The following species has been well known in our cabinets for

many years, and has given rise to much discussion as to its proper

value. It is generally conceded to be a well-marked variety of

ligneus, but certain characters not heretofore dwelt upon lead me

to believe that it is specifically distinct.

Hi. litigiosus n. sp.—Black, shining, the pubescence rather long, sparse ;.

elytra with two transverse fascie, one before basal third, the other just behind

the middle, both broadly interrupted at the suture and not attaining the lateral!

margins. Head as in ligneus. Prothvrax nearly as in ligneus, but slightly

larger. lytra parallel in the female, distinctly attenuate from base to apex

in the male, subdepressed. Length 9.0-12.0 mm.; width 3.0-4.3 mm.

California.

The principal distinctive features of this species, apart from color,

are the following :—

1—The prothorax is relatively larger and the elytra distinctly

narrowed from the humeri to the apex in the male, the latter being

shorter and nearly parallel in the corresponding sex of ligneus.

2—The elytral pubescence is longer and rather finer, and the

punctures do not become so decidedly finer and closer toward apex,

this character applying more especially to the male.

3—The intermediate tarsi of the male of ligneus are robust or

subdilated, with the second joint about as wide as long, while in

the same sex of litigivsus they are slender, with the second joint

fully one-half longer than wide; corresponding differences are

observable also in the anterior tarsi of this sex, the second joint

being strongly transverse in ligneus, and scarcely wider than long

in litigzosus.

It is difficult to believe that these differences merely indicate

varietal modification, especially as they are confirmed by ample

series in my cabinet. Zigneus is found throughout the United

States, and is equally abundant in California, while liéigiosus is

confined as far as known to the latter locality.

PHYMATODES Muls.

This genus is not separable from Callidium by any decided modi-

fication of the legs, sterna or trophi, and depends for its validity

almost entirely upon habitus; the latter may however often become

more important, as a generic character, than the modification of any

special organ, as is apparently evidenced in the present case.

In Phymatodes the eyes are singularly inconsistent in degree of

emargination, the two lobes being generally connected by a rather

wide faceted band, but in some species, as varius, this band or

isthmus becomes very narrow, bearing a single line only of some-

what coarser facets, and in amenus almost entirely disappear, the

eyes being as completely divided as in Tetropium. Thus a charac-

ter, apparently important in the Asemini, becomes here quite value-

less.

P. obliquus n. sp.—Oblong, subparallel, rather depressed, black

throughout, the coxe alone pale testaceous, moderately shining, each elytrou

with two narrow fascie, oblique toward the suture, the anterior at basal third

feebly and posteriorly so, the posterior at apical fourth anteriorly and strongly.

Head somewhat finely, contusedly punctate; antenne in the male slightly

longer than the body, slender, but slightly stouter toward base, the second

joint less than one-half as long as the third, the latter slightly longer than

the fourth and a little shorter than the fifth, in the female more than three-

fourths as long as the body. Prothorar very slightly wider than long; apex

and base truncate, the former slightly the wider; sides arcuate; disk widest

at about the middle, finely punctate, the punctures dense and scabrous later-

ally, very sparse toward the middle. lytra feebly narrowed from base to

apex, and, at base, but little wider than the prothorax in the male, parallel

and much wider than the latter in the female, finely, very densely punctate,

much more sparsely so in basal third. Legs long, with the femora strongly

pedunculate and clavate in the male, shorter and a little more slender in une

female. Length 7.2-7.6 mm.; width 2.3-2.5 mm.

California (Santa Clara Co.). Mr. Harford.

The three specimens represent a species allied to varius, but

differing in the much finer, sparser punctuation of the pronotum,

denser punctures of the elytra, with shorter finer pubescence, longer

antenne and much more oblique posterior fasciee.

This species bears no resemblance to decussatus of which I have

Coleopterological Notices, ITT. 27

a large series; the body is more robust, the femora more clavate,

and the antennal joints much more elongate.

CHROTOMA 1. gen.

Body elongate, densely pubescent, the elytra with small denuded spots.

Head not quite vertical, the front feebly concave between the antenne, longi-

tudinally and finely sulcate, divided from the epistoma by a rather fine but

distinct sulcus; eyes deeply emarginate, large, coarsely faceted; palpi slightly

unequal, elongate, slender, the last joint elongate, nearly parallel, the apex

minutely, transversely truncate; antennal tubercles slightly and obtusely

prominent; antenne (female) two-thirds as long as the body, the third joint

very long, slender, slightly enlarged near the apex, three-fourths longer than

the fourth, the latter slightly shorter than the fifth, joints five to eleven sub-

equal in length, compressed, the edges very acute, the flat sides feebly swollen

along the middle, the apex acutely angulate and very prominent but not

spinose internally, tenth joint slightly shorter than the ninth or eleventh, the

latter with a small conical apical process. Prothorax without lateral spine

and with five dorsal callosities. Scutellum acutely triangular. Elytra with

a stout acute sutural spine. Front coxal cavities angulate externally, sepa-

rated by a narrow but distinct prosternal lamina. Middle coxe distinctly

separated, the cavities open externally. Metathoracic episterna moderate in

width, scarcely visibly narrowed from base to apex. Legs short, slender, the

basal joint of the hind tarsi rather longer than the two following combined.

This genus, together with Brothylus and Osmidus of LeConte

and Perilasius Bates, constitutes a group of species which is very

difficult to treat; they are all allied to the European Hesperophanes.

Chrotoma differs from Brothylus‘and Osmidus in the peculiar elon-

gate subparallel form of the last joint of both palpi, and from Peri-

lasius, to which it is probably more closely allied, in the slender,

almost parallel femora, absence of lateral thoracic spine in the

female, and very different disposition of the dorsal callosities, appa-

rently also in the form of the terminal palpal joints.

C. dunniana 0». sp.—Parallel, moderately, evenly and cylindrically

convex, piceous-black throughout, the antenne and legs concolorous, the

elytra with a marginal and discal vitta of pale rufo-testaceous, feebly evident

through the dense vestiture and which become more distinct toward base ;

pubescence moderate in length, coarse, recumbent, very dense throughout the

body and legs, pale grayish-white, the small elytral denudations bearing long

erect flying hairs, the latter also present rather densely on the prothorax and

sparsely on the legs and toward the base of the antenne. Head three-fourths

as wide as the prothorax, the antenne clothed with fine recumbent ashy

pubescence toward base, which becomes slightly darker and excessively minute

28 Coleopterological Notices, IIT. —

and dense toward apex. Prothorax very slightly wider than long, the base

and apex equal, truncate, the sides evenly and rather strongly arcuate; disk

with four small denuded callous spots, which are granulato-rugose but not

elevated and arranged in a transverse arc at about the middle of the length,

the fifth slightly more elongate-oval on the median line at basal third; on

each side of the latter there is also visible a minute callus, which is probably

not constant, the median callus slightly impressed and polished. Llytra about

one-fifth wider than the prothorax, parallel, the sides straight, the apex

abruptly, broadly rounded, subtruncate in the middle; disk with fine, rather

dense punctures, almost completely concealed by the vestiture, the denuded

spots small, numerous, arranged without order, smooth, polished and flat.

Length 16.5 mm.; width 4.3 mm.

Texas (El Paso). Mr. G. W. Dunn.

The vestiture is longer, coarser and denser than in Brothylus,

and almost completely conceals the sculpture. The species is repre-

sented by a single female.

ELAPHIDION Serv.

Hypermallus Lac.; Aneflus Lee.

The following species belongs near irroratum and mucronatum,

but has the outer joints of the antenne strongly and finely carinate

along the middle of the flat sides, being thus a highly typical mem-

ber of the group of species generically separated by Dr. LeConte

under the name Aneflus; it will be noticed that the outer joints

of irroratum are also strongly carinate. In fact Aneflus not only

cannot be regarded as a genus, but apparently does not form even a

distinctly marked group, the tendency to carination being apparent

in the majority of species and to a very variable degree, so that it

is impossible to assign any limits to the group.

E. arizonense n. sp.—Form as in irroratum, castaneous throughout,

scarcely more shining than mucronatum; pubescence very short and sparse,

finely and rather sparsely marmorate on the pronotum and elytra with small

irregular patches of denser pale yellowish pubescence, four of the spots of the

pronotum forming a transverse row just before the middle. Head coarsely,

densely punctate; antenne (male) about two-fifths longer than the body,

stout, third and fifth joints equal in length, the fourth distinctly shorter,

three to five strongly spinose internally, the remainder with a small inner

and outer spine at apex, joints eight to eleven with a fine strong median

carina along their compressed sides. Prothorax very nearly as long as wide;

apex and base subequal, truncate; sides broadly, very obtusely subangulate

at or just behind the middle; disk with a small, elongate, almost impunctate

median callus just behind the middle, and a subcallous line at lateral fourth

Coleopterological Notices, III. 29

extending from apical two-fifths to the base, which is more coarsely punctate

and more pubescent; other regions dull, coarsely punctate, the punctures

densely crowded and themselves finely densely punctate, forming an intricate

but coarse sculpture. Scutellum densely pubescent. lytra a little less than

three times as long as wide, at base distinctly wider than the prothorax ; sides

feebly convergent from base to apex, the latter truncate, the outer spine very

short and broadly obtuse, the sutural short, narrower and more acute ; disk

sparsely punctate, the punctures very coarse toward base but fine in apical

half. Under surface nearly as in mucronatum, the legs longer and the femora

much stouter in the male, not spinose ; posterior tibiz carinate as in irroratum.

Length 21.0-23.0 mm.; width 5.6-5.8 mm.

Arizona.

The two specimens, which are from the Levette cabinet, are both

males. Although by the characters given for Aneflus, this species

should be placed near protensum, I cannot recommend that it be

withdrawn from the neighborhood of ¢rroratum, and if it is trans-

ferred to Aneflus, ¢rroratum must go also; but in truth there is

no such group in nature as Aneflus, and it should therefore be

suppressed and the species returned to Elaphidion.

E. levettei n. sp.—Elongate, very slender, parallel, dark rufo-castane-

ous, shining, the pubescence silvery-white, not at all maculate on the protho-

rax, arranged in four even parallel vitte on each elytron, which do not quite

attain the apex, and which are separated by narrower, very sparsely pubescent

lines, also with a series of small widely separated denuded spots on each side _

of the suture. Head rather coarsely, densely punctate; antenne wanting in

the type. Prothorax much longer than wide, the apex subtruncate, distinctly

narrower than the base; sides feebly swollen just behind the middle, thence

feebly convergent and nearly straight to the apex, and parallel and feebly,

broadly sinuate to the base; disk very coarsely, deeply, densely punctate, the

punctures tending to coalesce transversely at the sides, with a small elongate

very uneven impunctate area at the middle. Scutellum densely white, small,

the pubescence not at all parted along the middle. lytra fully three times

as long as the head and prothorax together, at base two-fifths wider than the

latter, each elytron very narrowly truncate at apex, and with two subequal

slender and well-developed spines; sides nearly straight, very feebly conver-

gent from base to apex; disk sparsely punctate, the punctures very coarse

toward base, gradually rather fine toward apex, the dense pubescence of the

vittz not borne from the punctures, but from almost invisible punctuation of

the flat interspaces, each of the sparsely pubescent lines having an extremely °

widely spaced row of coarser punctures, each bearing a long flying hair, one

of the latter borne also from each of the small sutural denuded spots. Legs

rather long, the femora very slender, not spinose at apex; tibie and tarsi

wanting in the type. Length 18.0 mm.; width 3.5 mm.

Arizona.

A single mutilated male from the Levette cabinet.

This species would almost seem to be generically distinct from

Elaphidion, but there are no characters relating to the under surface

by which it can be separated. The form of the body and size are

almost exactly as in swbpubescens, near which it may be placed for

the present.

RHOPALOPHORA Cerv.

The following species is allied to longipes but differs in its broader

form :—

R. meeskei nun. sp.—Elongate, subparallel, deplanate above, black

throughout, the prothorax above and beneath rufo-ferruginous ; integuments

dull and strongly alutaceous. Head somewhat coarsely, deeply punctate:

antenne one-half longer than the body in the male, scarcely longer than the

latter in the female, very slender, filiform, the basal joint much thicker. Pro-

thorax but very slightly longer than wide; base broadly emarginate, scarcely

one-half wider than the apex; sides strongly arcuate at basal third, thence

convergent anteriorly ; disk moderately constricted laterally at the apex and

just before the base, broadly, feebly biimpressed, the impressions joined by a

short transverse impression, the pubescence yellow, forming two broad longitu-

dinal lines. lytra nearly as in longipes, but more finely and densely cribrate.

Legs as in longipes. Length 7.5-8.4 mm.; width 1.7-1.9 mm.

New Mexico (Las Vegas). Mr. H. Meeske.

In longipes the form is very slender, the prothorax much longer

than wide, truncate at base, with the punctures extremely fine and

sparse, while in the present form the punctures are quite coarse and

distinct. In longipes the pronotum is not at all impressed, and the

lines of extremely short fine pubescence are very narrow.

The species of Rhopalophora within our limits may be recognized

as follows :—

Pronotum impunctate ; large species, 12 mm. in length........... laWicollis

Pronotum punctate ; smaller species, not exceeding 9.5 mm. in length.

The species of this genus with tuberculate sides of the prothorax

may be easily distinguished as follows :—

Prothorax more or less strongly transverse, very densely, confluently punc-

tured and densely pilose.

Antenne of the male rather short, never much longer than the body, those

of the female very short and stout, with the joints scarcely more than

twice as long as wide.

Elytral punctuation very coarse, becoming slightly finer toward apex, the

punctures always distinctly separated..............000- PuUNCctatus

Elytral punctuation finer, becoming extremely dense toward apex.

The posterior legs are notably longer than the four anterior

throughout the genus, as usual in this part of the family.

C. longipennis n. sp.—Elongate and slender, the female more robust,

oblong and parallel, pale brownish-testaceous throughout, the legs, antenne,

a more or less narrow fusiform sutural line not closely approaching the base,

and the pronotum except laterally, black; integuments moderately shining ;

three-fourths as long as the body, slender, not distinctly compressed, the

intermediate joints from three and one-half to four times as long as wide.

Prothorax from one-half (male) to nearly once (female) wider than long, the

lateral tubercle strong, the apex quite distinctly narrower than the base; disk —

extremely densely punctate, a very short narrow line in the middle usually

more or less impunctate. lytra at base as wide as the prothorax, each elytron

narrowly truncate at apex and obtusely but very distinctly angulate exter-

nally; disk of each with the usual three fine lines, rather finely, very densely

punctate toward apex, the punctures still dense but coarser toward base.

Length 15.0-19.0 mm.; width 4.4-5.7 mm.

New Mexico.

Related to intermedius, but larger and with much finer, denser

punctuation, and black legs and antenne. In intermedius the

-elytra are rounded behind and not truncate and angulate or even

prominent externally as in longipennis; this is an unusual char-

acter in the present genus, but may be perceived also to a less

degree in hirtipes Lec.

Four specimens from the Levette cabinet.

C. crassipes n.sp.—Robust, subparallel, black to piceous-black through-

out, the elytra and entire abdomen pale brownish-testaceous ; lustre of the

elytra rather strongly shining as in punctatus; pubescence long, dense and

pilose on the pronotum, rather long subrecumbent dense and conspicuous on

the elytra, pale throughout. Head rather small, the antenne (male) very

long and slender, much longer than the body, the third joint slightly shorter

than the prothorax. Prothorax coarsely, extremely densely punctate, with a

small indefinite median spot which is sparsely punctate; lateral tubercles

moderate ; disk (male) one-half wider than long, the apex distinctly narrower

than the base. Llytra at base distinctly wider than any part of the prothorax,

two and one-third times longer than wide, rounded behind, each elytron very

narrowly feebly sinuate at the suture; sides rather strongly convergent from

base to apex; disk very coarsely punctate, the punctures becoming smaller

but extremely dense toward apex, the three fine lines distinctly traceable.

Legs black, the anterior and intermediate very short, with the tarsi dilated,

the posterior much longer, with the tarsi two-thirds as long as the tibie,

robust, the second joint nearly one-half longer than wide. Length 14.0 mm. ;

width 4.5 mm.

A single male example from the Levette cabinet. This species

is intermediate between punctatus and intermedius, possessing the

of intermedius, and, in the latter, the posterior tarsi are very short

but slender, with the second joint not longer than wide.

C. mitidicollis n. sp.—Slender, strongly convex, subcylindrical,

strongly shining throughout, intense black, the median parts of the meta-

sternum and the abdomen pale rufous; elytra very pale flavate, with a

slender fusiform sutural space black; pubescence rather short and sparse,

slightly longer and more erect on the pronotum. Head small; antennz

(male) fully one-third longer than the body, slender. Prothorax two-fifths

wider than long, strongly convex and coarsely, not very densely punctate,

the apex truncate, much narrower than the base, lateral tubercle small but

distinct. lytra two and three-fourths times longer than wide, at base equal

in width to the widest part of the prothorax, the sides very feebly convergent

thence to the apex, each elytron narrowly and almost evenly rounded behind ;

disk very coarsely, deeply punctate, the punctures well separated toward

base and becoming finer but not much closer toward apex. Legs slender;

hind tarsi three-fourths as long as the tibie, with the second joint a little

longer than wide. Length 10.5-12.5 mm.; width 3.3-3.8 mm.

Arizona (Tugson). Mr. Wickham.

This species is allied somewhat to pulchellus, but differs con-

spicuously in many characters as detailed in the synoptic table; in

addition it may be noted that the prothorax is larger and longer

than in pulchellus, with the extremely slender and acute lateral

prolongation of the basal angles much more conspicuous. It is

represented before me by four specimens all of which are males.

The male appears to be more abundant than the female in all of the

species of this genus.

SPH EX NOTHECUS Dup.

Ischnocnemis Lec. nec Thoms.

The Mexican species allied to this genus form a very perplexing

mixture, and I have several in my cabinet which cannot be satisfac-

torily assigned to any of the described genera. The parts most

useful in generic identification are the mesosternum, posterior tarsi

and scutellum, but the last is probably much the least important

of the three. The presence or absence of raised ivory vitte is, as

remarked by Mr. Bates, a character of subordinate import, and in

Sphenothecus we have species with simple elytral disk like sutwralis,

others having raised coste, and others again with simple narrow

pubescent vitte.

Spheenothecus is allied to Mannophorus, but differs in its protu-

more finely attenuate scutellum. The true Ischnocnemis has the

The male antenne are always much shorter in su¢uralis than in

rubens, and are generally not more than two-thirds longer than the

body, the eyes also are more narrowly separated dorsally than in

rubens. The three species agree in the form of the elytral apices

which are strongly, very acutely dentiform but scarcely spinose

externally. Rubens was obtained in great abundance by Mr. Dunn

In various parts of southern Arizona and California, and suturalis

by Mr. Wickham at Tugson.

STENOSPHENUS Hald.

With the exception of nofatus our species seem to be quite local

in distribution ; the following belongs near lepidus Horn :—

S. longicollis n. sp.—Slender, elongate, subparallel, polished, the

elytra slightly less so than the prothorax and minutely evenly reticulate ;

body piceous-black, the femora red, piscescent near the apex; prothorax red,

clouded with piceous toward the sides; pro- and mesosterna red ; pubescence

coarse, moderate in length, sparse. Head finely, longitudinally canaliculate ;

antenne (male) very slender, fully three-fourths longer than the body, joints

three to five spinose internally at apex. Prothorax distinctly longer than

wide; sides broadly, evenly arcuate, gradually convergent anteriorly and

abruptly so near the base which is much wider than the apex ; disk widest at

basal third, with a few fine, widely dispersed punctures toward the sides only.

Scutellum small, rounded, densely flavo-pubescent. lytra three times as

long as the prothorax, and, at the base, one-fourth wider; sides feebly con-

vergent and nearly straight from the humeri to apical fourth or fifth, then

gradually more strongly convergent to the apex, each elytron being narrowly

truncate, the truncation bisinuate and limited internally and externally by a

minute acute dentiform process, which is not sufficiently elongate to be termed

spinose; disk rather finely but deeply, sparsely, evenly punctate throughout,

the punctures perforate and without trace of definite arrangement. Length

10.0 mm. ; width 2.5 mm. |

Texas.

A single male, probably received from Mr. Dunn, and without

any more definite locality. It differs from lepidus in having the

entire prosternum in front of the coxe strongly depressed and

coarsely densely punctato-rugulose, with the exception of a wide

polished apical margin; in lepidus this space is divided by a polished

longitudinal elevation, thus forming two depressed areas. Longi-

collis does not appear to be referrable to any of the described Mexi-

can species.

XYLOTRECHUS Chev.

The species insignis of LeConte, is remarkable for its pronounced

sexual disparity. A few years since I took a series of six speci-

mens from some low alder-like trees near the banks of the Trinity

River, in Humboldt Co., California, which upon cursory examina-

tion seemed to represent a distinct species near insignis. Subse-

quently I received a number of specimens from other parts of the

State.

The Humboldt specimens are uniformly pale in color, with the

prothorax large and transversely subquadrate, and the markings

indefinite and more or less confused with the ground color by dis-

persion of the pale hairs; upon close study all of these specimens

prove to be males. The female, represented before me by three

perfectly homogeneous examples, is black, and has the prothorax

narrower and the markings always distinctly and abruptly limited.

Although such striking sexual differences are unusual or alto-

gether unknown in our other species of this genus, it appears to be

a more common condition in-the allied Mexican genus Ochrethes

Chev., a seemingly undescribed species of which, represented in my

cabinet by a good series, having the markings suffused in the male

but distinct in the female.

36 Coleopterological Notices, ITI.

THESALIA n. gen.

This name is proposed for a small species, recently described by

Mr. Leng (Ent. Amer., VI, p. 108) under the name Acmeops lisa.

Briefly, its characters may be expressed as follows :—

Front before the antenne nearly vertical. Antenne long and slender,

rather approximate and dorsal in their insertion. Eyes moderate, convex,

with a small distinct but moderately deep sinuation. Neck strongly con-

stricted, the constriction extending entirely across the dorsal surface. Legs

moderate, the posterior tarsi rather short, densely pubescent beneath, the

basal joint subequal in length to the next two together.

The genus Thesalia should be placed between Leptalia and

Encyclops in our lists, and agrees with the former in most of its

characters.

The prothorax differs greatly from either Leptalia or Encyclops,

being long and slender, much longer than wide and narrower than

the head, rather coarsely and sparsely punctate and not at all im-

pressed or canaliculate along the middle. In Hncyclops cerulea

both the head and pronotum are dull and densely covered with a

reticulation formed by fine strongly elevated lines.

I have before me a single representative of Th. lisa collected in

Marin Co., California, by Mr. Dunn. It does not entirely agree

with the description given by Mr. Leng, having the pronotum

sparsely punctate toward the middle, without a well-defined impunc-

tate area, the elytra black with the punctures throughout decidedly

sparse as well as extremely coarse and deep, and with the sides

feebly convergent from base to apex. The hind tarsi have the two

basal joints densely pubescent beneath but not as densely so as the

third, and are strongly fimbriate along the sides. The specimen

here noted is probably the male of the original type, which is with-

out doubt a female.

CENTRODERA Lec.

There is before me a specimen which I took on the summit of

Mt. Diablo, near San Francisco, which is pale castaneous in color

throughout and uniformly and sparsely pubescent. The length is

16.5 mm., and the prothorax is much longer than wide, strongly

constricted at basal and apical fourth, with the apex much narrower

than the base and the disk broadly, deeply impressed along the

middle. The eyes are remarkably large and the antenne are

Coleopterological Notices, III. 37

slightly longer than the body, with the joints four to eleven pale

testaceous toward base and black in apical third. I think that this

is probably the male of C. nevadica Lec., which was described from

a unique female.

TOXOTUS Serv.

-™. lateralis n. sp.—Rather short and stout, moderately shining, black

throughout the body, legs and antenne, the abdomen rufo-testaceous and the

elytra with a pale narrow marginal vitta which does not quite attain the apex ;

pubescence short, cinereous, rather sparse, longer but not much denser on

the prothorax. Head rather finely densely and confluently punctate, broadly

tumid between the eyes, the latter rather large and convex; antenne but just

visibly shorter than the body, rather stout, compressed, the fourth joint nearly

two-thirds as long as the third and about three-fourths as long as the fifth,

the third joint three times as long as wide. /Prothorax a little longer than

wide, strongly constricted near apical third and basal fourth, the apex four-

fifths as wide as the base, broadly arcuate ; sides angularly tuberculate at the

middle; disk finely, densely punctate, the punctures sparser in the apical

constriction. lytra at base nearly one-half wider than the prothorax, two

and one-half times longer than wide, the sides very strongly convergent from

base to apex and nearly straight; each elytron narrowly and obliquely trun-

cate, the truncature straight, the outer angle acute, not rounded, the inner

dentiform ; humeri rather prominent, less than right, narrowly rounded ; disk

nearly flat, abruptly perpendicular at the sides, very finely, densely punctate

and also with slightly larger widely dispersed punctures. Under surface punc-

tured like the elytra, the abdomen more sparsely. Legs slender, moderate in

length. Length 13.0 mm.; width 4.0 mm.

California (near San Francisco).

The single male specimen which I took at the summit of Mt.

Diablo, represents a species somewhat allied to the eastern trivit-

tatus Say (vittcger Rand.), but differing in its unusually long, and,

at the same time, stout and compressed antenne. The elytral trun-

cature is as in trivittatus, but with the sutural tooth much larger

and more conspicuous.

ANTHOPHILAX Lec.

A. subvittata n. sp.—Moderately robust, rather convex, piceous-black ;

legs and antennz piceo-testaceous ; elytra pale luteo-testaceous, with a broad

common sutural and narrow submarginal vitta of piceous-black, the vitte

generally feebly marked and sometimes evanescent; pubescence extremely

short and sparse, on the elytra consisting of very minute erect sete borne

from the punctures. Head finely, densely punctate, finely canaliculate be-

tween the antenna, the latter three-fourths as long as the body, with the

third joint distinctly longer than the fourth but much shorter than the fifth.

Prothorar slightly wider than the head and a little wider than long, the apex

very slightly narrower than the base, both feebly arcuate; sides strongly,

obtusely tuberculate at the middle; disk finely, densely punctate, scarcely at

all impressed along the middle where the punctures are sometimes but not

always sparser. Jlytra at base not more than one-third wider than the

prothorax, about two and one-third times longer than wide; sides distinetly

convergent from base to the apex, which, conjointly, is broadly and evenly

rounded ; disk very coarsely and sparsely punctate toward base, the punc-

tures becoming gradually fine toward apex and along the suture. Length

9.3-11.0 mm.; width 3.2-4.0 mm.

Colorado ?

The five specimens before me are without definite indication of

locality, but as they are from the Levette cabinet they were in all

probability taken in or near the region above stated. These speci-

mens are apparently all males, and the species appears to be related

to tenebrosa, which is described from a unique female. JI do not

think however that subvittata can be the male of tenebrosa, for in

that case the general direction of the sexual differences, as shown

in mirifica by Dr. Horn, would be rather reversed, the elytra in

the male of mirifica being almost impunctate, while in the female

they are very coarsely so.

ACM ZEOPS Lec.

The series in my cabinet seem to show that A. subpilosa is a

species entirely distinct from dupina. The former is extremely

sparsely punctate, the pubescence very easily removable, but denser

and persistent in a very narrow line bordering the elytral suture,

giving it a narrowly vittate appearance, while in dupina there is no

indication of this sutural condensation, and the discal punctures are

between two and three times as dense, the pubescence being much

nore persistent.

The species longicornis and ligata are perfectly identical, and

the latter should be regarded as a synonym of the former, not a

variety. Gabbula isa synonym of proteus and not a variety, as it

is printed in our lists.

A. Variipes n. sp.—Rather slender, strongly convex, shining, deep

black ; antenne dark brown, with the basal joint darker and blackish; ante-

rior legs throughout and the intermediate and posterior femora feebly and

suffusedly near the coxe only, pale rufo-testaceous ; pubescence very short

and sparse, longer on the anterior portions. Head about equal in width to

Coleopterological Notices, ITT. 39

the prothorax, flattened above, rather coarsely, extremely densely punctate

and dull; sides behind the eyes parallel for a very short distance, then

rounded to the neck; tempora shorter than the eye; antenne very slender,

subequal in length to the body, third joint much shorter than the fifth and

but slightly longer than the fourth, the fifth thicker toward apex than the

others. Prothorax slightly wider than long, the apex broadly arcuate, three-

fourths as wide as the base; sides strongly but evenly arcuate, sinuate near

base and apex; disk narrowly impunctate but scarcely impressed along the

middle, rather coarsely, very densely punctate, the punctures generally not

in actual contact. Scutellum rather longer than wide, acutely rounded at

apex. lytra at base not quite one-half wider than the prothorax, two and

one-half times as long as wide; sides rather strongly convergent from base to

apex, the latter narrowly rounded, not at all truncate; disk very coarsely,

deeply, not closely punctate, the punctures becoming slightly smaller but not

denser toward apex, each bearing a very short coarse hair. Jegs rather long

-and slender. Length &.0-8.8 mm.; width 2.5-3.0 mm.

California (Sta. Cruz Co.).

This species is somewhat allied to longzcornis and basalis, but

differs in its shorter, more convex form, much coarser, sparser

punctuation, shorter, sparser pubescence, and also in coloration ;

from atra it differs greatly in the parallel sides of the head behind

the eyes, in the distinct basal constriction and prominent basal

angles of the prothorax, and in its much more crowded pronotal

punctuation.

A specimen from Nevada is nearly similar, but has the pubes-

cence still more minute and the elytra parallel and scarcely more

than twice as long as wide; this is probably the female of the

above-described male.

STRANGALIA CServ.

The sexual characters of this genus form an exceedingly inter-

esting study, as they manifest themselves strongly and in several

directions. The fifth segment of the male is sometimes very large,

dilated and strongly excavated beneath as in virdlis, and, to a less

degree, strigosa; in addition it will be noticed that this segment is

also invariably impressed or excavated beneath toward tip in the

female as well as the male, and in sexnotata the impression is quite

as deep in the former as in the latter sex, and involves even more

of the surface of the segment.

The community of impressions and excavations of the fifth ven-

tral segment to both male and female is noticeable in many parts

40 Coleopterological Notices, ITI.

of the Heteromera, and I have alluded to it before under the genus

Blapstinus (Ann. N. Y. Acad., V, p. 418). It is probable that this

fact has a more far-reaching import than may be apparent to us at

present.

The antenne of the male have, on the side at the apex of each

of the outer joints, a large elongate-oval depressed area which is

glabrous, but over which there are generally scattered a very few

coarse spinose sete. These sensory depressions are usually much

less developed in the female than in the male, and are sometimes

almost obsolete in that sex; they vary slightly in form and depth

in the various species.

I take the present occasion to call attention to a species allied to

sexnotata, which may be described as follows from the female :—

S. montana un. sp.—Moderately robust, rather dull and alutaceous in

lustre, pale rufo-testaceous throughout, the tarsi and three or four terminal

joints of the antenne picescent ; elytra each with three black spots arranged

as in sexnotata; pubescence rather short, coarse and sparse. Head finely, very

densely punctate, a posteriorly angulate area immediately behind the epistoma

impunctate and highly polished; epistoma and labrum finely, sparsely punc-

tate and shining; antenne (female) two-thirds as long as the body, stout,

cylindrical, the joints compactly joined toward apex and without trace of

sensitive apical areas, third joint one-half longer than the fourth. Prothorax

fully as long as the basal width, finely, strongly constricted just behind the

apex, the latter truncate and less than one-half as wide as the base, the latter

broadly bisinuate; basal angles laterally produced, acute and prominent ;

sides broadly sinuate toward base; disk immaculate, evenly convex, rather

coarsely and sparsely punctate. lytra at the humeri quite distinctly wider

than the prothorax, nearly three times as long as wide, the sides strongly

convergent from the rounded humeri to the apex; each elytron truncate at -

apex, the truncation but slightly oblique; disk rather coarsely, sparsely

punctate. Under surface finely, sparsely punctate and pubescent. Length

12.5 mm.; width 3.5 mm.

New Mexico (Las Vegas). Mr. Meeske.

Immediately distinguishable from the female of seanotata by the

truncate apices of the elytra, and stouter antenne; the antenne

and greater part of the legs are black in sexnotata, but two speci-

mens before me from Texas seem to indicate that they may occa-

sionally become pale throughout, this not being a character of great

importance. The elytra toward apex are much less dehiscent in

montana than in sexnotata, and the surface in the former is less

shining and more finely punctate.

OPHISTOMIS Thoms.

The species recently described by Bates (Biol. Cent.-Amer. Col.,

V, p. 39) as levicollis is represented before me by three specimens,

perfectly homogeneous as regards color, and belonging to the variety

designated “6” (1. c., page 279). These specimens were formerly

included in the Levette cabinet, and are labeled ‘‘ Arizona.’”? This

is therefore one of those tropical species of exceptionally extended

northern distribution, of which Xystropus californicus Horn, is

another notable example.

The elytra in O. levicollis are obliquely and rather widely trun-

cate at apex, the line of truncation straight and the outer angle very

acute but not appreciably produced. The elytral punctuation varies

considerably in density, but is generally finer and confused toward

apex and very coarse and sublineate in distribution toward base.

The humeri in the specimens alluded to are clouded with reddish-

testaceous. The intermediate tibie are quite distinctly clavate.’

LEPTURA 6erv.

A specimen of nigrella Say, from Colorado, before me, has the

elytra bright red throughout, with the exception of a narrow and

even black marginal vitta in apical third.

The three following species appear to be new :—

L. serpentina n. sp.—Rather slender and convex, feebly shining,

black throughout, the legs and antenne generally pale; pronotum with the

apical and basal margins bright sulphureo-pubescent ; elytra each with four

transverse bands of the same color, one at the base just behind the scutellum

narrowly interrupted at the suture, the second just before the middle, third

at posterior third, and the fourth near the apex ; under surface clothed with

yellow pubescence, the abdominal segments more distinctly so near the apex

1 Some time after the above paragraphs were written, I sent one of these

specimens to Mr. Bates, and take the liberty of quoting the following lines

from the very courteous letter recently received in reply :-—

‘*T have examined your Ophistomis, supposed to be from Arizona, and find

it cannot be specifically distinguished from O. levicollis. The punctuation is

a little more sparse, but a rather more important difference is the relative

greater length of the elytra, and the shorter outer acute angle of the trunca-

ture. I donot consider these differences specific, but note them only as some

evidence that the specimen comes from a different locality from those recorded

in the Biologia, 7. e., Oaxaca to Panama.”’

the body, slender, filiform, the third joint much longer than the fifth, the

latter distinctly longer than the fourth, (female) nearly three-fourths as long

as the body, with the joints proportioned nearly as in the male. Prothorax

about as wide as Jong, campanulate, with the sides inflated and broadly sub-

angulate before the middle, the basal angles acute and strongly produced out-

wardly and posteriorly ; disk almost evenly convex, with a small impunctate

vitta near the base, rather strongly and somewhat sparsely punctate in the

Idaho.

Greatly resembles trzbalteata Lec., and differs from that species

in much the same way that nitens Forst. (zebra Oliv.) does from

leta Lee. The form in the male is more slender than in tribalteata,

with the elytra less strongly narrowed from base to apex, and with

the apical truncation much less oblique; the antenne are much

longer and more slender, and the third joint is distinctly shorter in

comparison with the next two; the dorsal punctuation is coarser,

deeper and sparser in the male but rather denser in the female,

and the transverse bands of the elytra are much narrower. The

antennee are always pale in serpentina and intense black in ¢ribal-

teata, and the head and eyes are smaller in the former than in the

latter.

L. haldemani n. sp.—Slender and rather convex, intense black

throughout the body, legs and antenne, the elytral humeri obliquely red ;

lustre moderately shining; pubescence short, sparse and inconspicuous.

Head wider than long, the tempora and base nearly as in sanguinea; surface

flat, very densely punctate; antennze (male) nearly as long as the body,

rather stout. Prothoraz much longer than wide, as in sanguinea, but much

less inflated or subangulate at the middle; disk rather coarsely, deeply and

extremely densely punctate, the punctures in close mutual contact, without

distinct median impunctate line except very narrowly toward base, the line

generally with a very fine impressed stria. lytra between two and three

times as long as wide, at base nearly one-half wider than the prothorax, the

humeri rounded but rather prominent; sides evenly and rather strongly con-

vergent from base to apex and straight; each elytron narrowly truncate at

apex, the truncation slightly oblique and straight or extremely feebly sinuate,

the angles obtuse; disk not very coarsely or densely punctate, the punctures

deep and perforate toward base, becoming finer and more or less asperate

base. Under surface very finely and densely punctate, more conspicuously

pubescent. Length 9.0-10.5; width 2.5-3.0 mm.

New Mexico.

The two specimens are males, and are from the Levette cabinet.

The species is allied to sanguinea, but differs greatly in coloration

and punctuation, and in the more narrowly and obliquely truncate

elytral apices. The red humeral maculation is similar in form to

that of Acmeops basalis.

L. lacustris n. sp.—Body, legs and antenne entirely black, the elytra

pale brownish-testaceous, sometimes feebly infuscate near the apex; lustre

moderately shining; pubescence moderately long, very short on the elytra.

Male.—Slender, very convex. Head wider than long, the sides behind the

eyes parallel for a short distance; hind angles right and narrowly rounded ;

surface feebly convex, densely and rather coarsely punctate; antenne three-

fourths as long as the body, rather stout. Prothorar as in sanguinea, rather

coarsely, deeply, very densely punctate, with a narrow impunctate median

line, the punctures nearly but not quite in mutual contact, the interspaces

polished. lytra two and one-half times as long as wide, at base one-third

wider than the prothorax; sides gradually and distinctly convergent from

base to apex, the latter very narrowly and obliquely truncate, the truncation

deeply sinuate; disk rather densely and strongly punctate, the punctures be-

coming slightly finer toward apex. Length 9.0-11.0 mm.; width 2.8-3.6 mm.

Female.—Moderately slender, smaller than the male, the upper surface much

less convex. Head similar in form to that of the male, but with the surface

very finely and excessively densely punctate and dull; antennz scarcely more

than one-half as long as the body, very slender. Prothorar similar in form to

that of the male, but with the surface extremely densely punctate, and with-

out trace of median impunctate line, the punctures scarcely smaller than in

the male and very much larger than those of the head. lytra scarcely more

than twice as long as wide, at base rather more than one-third wider than the

prothorax, the humeri distinctly rounded but much more prominent than in

the male; sides almost parallel, feebly convergent toward apex, the apical

truncation as in the male; disk very coarsely, deeply, densely punctate, the

punctures becoming much finer toward apex, coarser toward base than those

of the male. Length 7.8-9.0 mm.; width 2.5-3.0 mm.

Michigan (Marquette). Mr. Schwarz.

This species is allied to sanguinea Lec., but differs in the much

stouter male antenne and in the radically different truncation of the

elytral apices; the latter in sanguinea is rather broad, scarcely at

all oblique, and is almost perfectly straight, the angles being blunt ;

in lacustris it is very much narrower, oblique, deeply sinuate and

with the angles, especially the exterior, very acute and prominent,

nearly as in canadensis. The sexual differences throughout the

body are extremely and unusually marked, and in the series before

me, the females are decidedly smaller than the males.

IPOCHUWS Lec.

The chief differences between this genus and Moneilema, apart

from the tribal characters relating to the support of the labrum and

size of the body, are the shorter and broader front, presence of long

tactile flying hairs on the body legs and antenne, and the great

divergence in form of the sexes. The last of these is one of the

most remarkable of the generic peculiarities of Ipochus, the male

being slender, strongly convex, with oval elytra, subglobular pro-

thorax and constricted neck, and the female more robust, subparallel,

the prothorax transversely subquadrate and the neck scarcely at all

constricted, the head being more deeply inserted. It will be observed —

therefore that the sexual differences are directly the reverse of those

of Moneilema, in which, when these are at all pronounced, the male

is more robust parallel and compact than the female, and with a

larger prothorax.

The following species are indicated by the material at hand :—

Elytra with three transverse, irrregular and more or less narrow fascie, the

first near the base, the second at apical third (viewed vertically), and

the third on the apical declivity, extending semi-circularly from the side

margins, crossing the suture midway between the second band and the

apex ; recumbent pubescence rather sparse; pronotum very coarsely,

deeply and not closely punctate, with two pairs of small discal pubescent

spots. Elytra broadly, deeply sinuate at apex when viewed along the

longitudinal axis of the body. Length 4.5 mm.; width 2.0mm. (San

Diego.) snes ens vine vee ciasieee sine son ace eos eenisee ote lnceitenseslaenienens sencilla San en Mil ommerEs

Elytra with two more or less narrow transverse fasciz, which are irregular

and zigzag in form, the first at the base, the second at apical fourth

(viewed vertically) ; in addition a small elongate-oval sutural spot near

the apex on the declivity. Body sparsely pubescent, the pronotal punc-

tures coarse, moderately close, distinct, the integuments shining. Head

finely, sparsely punctate; antennze about as long as the body, the outer

joints feebly annulated at base. Prothorax one-fourth wider than long,

the sides rounded, more convergent toward base, the latter much narrower

than the apex; discal pubescent spots evanescent, the fine pubescence

very sparse, short and inconspicuous. Elytra one-third longer than wide,

in the middle one-third wider than the prothorax; sides rounded, the

apical portion of the disk perpendicular and deep; apex not appreciably

emarginate when viewed longitudinally. Abdomen sparsely pubescent.

Length 7.0 mm.; width 3.4 mm. (female); in the male the length is

5.0-7.0 mm. ; width 1.6—2.2 mm. (Los Angeles.)....submitidus n. sp.

Elytra each with two transverse fasciz, the first subbasal, the second very

wide, with uneven margins, extending from the middle to the apex

(viewed vertically) and with a prolongation posteriorly along the suture.

Body robust, compact, the head and pronotum extremely densely pubes-

cent, the vestiture completely concealing the surface lustre and punctua-

tion, the elytra slightly shining and less densely pubescent. Head rather

strongly, somewhat closely punctate; antenne nearly as long as the body,

the outer joints scarcely annulate at base. Prothorax fully one-third wider

than long, the base much narrower than the apex; disk with two pairs

of small discal pubescent spots, and another which is median and more

posterior. Elytra two-fifths longer than wide, behind the middle but little

wider than the prothorax; apex broadly, feebly, subangularly emargi-

nate (viewed longitudinally); sides very feebly arcuate; disk finely, very

DAMM. (San Diego.).......scccecsecseccecceccccccceseeseee PUMWESCEMS N. sp.

The species above identified as fasczatus agrees in every particu-

lar with the type in the LeConte cabinet.

All the characters of the above diagnoses are taken from the

female, except when otherwise noted. Two males which I obtained

from the blossoming branches of the Monterey pine, near the town

of that name, seem to indicate another species, which the absence

of the female prevents me from describing at present. Another

“specimen from San Diego, resembles subnitidus, but is still more

shining and sparsely pubescent, and has a large impunctate median

area of the pronotum, which is finely and deeply canaliculate; it is

probable also that this is a distinct species, but more confirmatory

material is necessary.

MONEILEMA Say.

The following species belongs to the subgenus Collapteryx as

defined by Dr. Horn :—

M. spimicollis n. sp.—Moderately robust and convex, the elytra sub-

carinate at the sides toward base, black, rather strongly polished, glabrous.

Head with a few fine punctures beneath the eyes and antenne, impunctate

toward the middle, the front separated from the epistoma by a deep transverse

impression ; antenne three-fourths as long as the body, with the fourth joint

alone annulate at basal two-fifths ; scape very long and thick, with a few fine

widely dispersed punctures. Prothorax strongly transverse, from one-third to

nearly one-half wider than long, the base and apex equal in width, feebly

arcuate ; sides parallel, feebly arcuate, the spine long, acute, directed upward

and backward; disk evenly convex, with a more or less incomplete and very

fine stria along the middle, the punctures very fine and widely dispersed, but

coarse and deep along the basal margin and on the flanks beneath the spine.

Elytra oval, from two-thirds to once longer than wide, the sides arcuate but

sometimes almost straight and parallel, scarcely wider than the prothorax in

the male but distinctly so in the female, very coarsely and sparsely punctate ~

in scarcely more than basal half. Posterior tarsi as in armata in form, but

with the second joint densely spongy-pubescent throughout, except along a

median line which becomes broad at base, the basal joint sometimes with a

small spot of dense yellow spongy-pubescence at each apical angle. Length

23.0-29.0 mm.; width 9.0-11.5 mm.

Arizona.

Four specimens from the Levette cabinet. This species differs

from gigas in its much shorter and more transverse prothorax and

smaller size, and from armata in the much longer and thicker

antennal scape, longer thoracic spines and in the more spongy

pubescent second joint of the hind tarsi. It should be placed im-

mediately after gigas in the catalogue.

The ashy pubescence of the fourth antennal joint forms a narrow

band extending from basal sixth or seventh of the Jength to about

the middle.

PSENOCERUS Lec.

The two species contained in my cabinet may be recognized as

follows :—

P. tristis n. sp.—Form nearly as in supernotatus, feebly shining ; pubes-

cence rather sparse and inconspicuous. Head finely but deeply and very

densely punctate; antenne scarcely three-fourths as long as the body, cylin-

drical, the third and fourth joints elongate and subequal, joints five to eleven

shorter and becoming still shorter near the apex, the joints compactly joined.

cent. Legs moderate; tarsi short and stout. Length 4.5mm.; width 1.2mm.

New Mexico?

A single representative, the habitat of which is somewhat doubt-

ful. The species is easily distinguishable from supernotatus by the

characters given in the table. The basal tubercles of the elytra, so

distinct in supernotatus, are barely perceptible in tristzs as broad

and feeble swellings of the surface.

MONOCHAMUS Serv.

M. obtusus n. sp.—Stout, subparallel, moderately convex, brown

throughout and marmorate nearly as in @itillator. Head deeply angularly

impressed between the antenne; front shining, sparsely pubescent, finely,

sparsely and unevenly punctate; antenne (male) two-thirds longer than the

body, slender, not at all annulate, (female) but slightly longer than the body,

distinctly annulate. Prothorax slightly wider than long, the lateral spines

well developed; disk shining, coarsely, confluently punctate, transversely

rugulose anteriorly, with an oblong impunctate median area; pubescence

moderately conspicuous, feebly and minutely marmorate laterally, with two

distant, discal spots before the middle. Scutellum glabrous, pubescent at

base especially toward the sides. lytra scarcely more than twice as long as

wide, parallel in basal half in the male and basal two-thirds in the female, at

base distinctly wider than the prothorax, the apices individually rounded,

broadly so in the female, a little less broadly in the male; disk very coarsely

punctato-rugulose toward base, sparsely and more finely punctate thence to

the apex. Abdomen densely pubescent, the pubescence whitish and finely,

unevenly marmorate or nucleated. Legs rather short and moderately slender.

Length 13.0-19.0 mm. ; width 4.7-6.8 mm.

California.

This species is not at all closely related to any other hitherto

described. In general it resembles ¢itcllator, but is smaller, shorter

and broader, with the apical angles of the elytra broadly rounded

even in the males. In the recent table given by Dr. Horn it may

be placed between scutellatus and confusor. The scutellum, which

is pubescent only toward the sides of the base, will readily serve to

distinguish it from any other of our species, and from oregonensis

it may be known by its rounded elytral apices, scutellum and colora-

tion. It is represented before me by a good series of six specimens

collected near the northern boundary of the State.

LEIOPUS Serv.

L. setipes n. sp.—Moderately robust, convex, piceo-testaceous, densely

clothed with dark luteous pubescence, devoid of fasciculate tufts of coarser

hairs, and with an anteriorly angulate white fascia behind the middle, also a

very feebly defined paler oblique line on each elytron near the apex. Head

extremely minutely, densely punctate when denuded ; eyes separated above by

a distance which is scarcely more than one-half as great as in wilti; antenne

slender, two-fifths longer than the body, nearly as in wilt? Prothorax one-half

wider than long, four-fifths as wide as the elytra, rather finely and closely

punctate, the pubescence very indefinitely variegated ; lateral spine short but

not at all blunt, just behind the middle, nearly as in wiltz, but slightly more

anterior in position. lytra three-fourths longer than wide; sides nearly

parallel in basal two-thirds, then obliqte to the apex, each elytron narrowly

and obliquely truncate; disk coarsely, deeply punctate when denuded, each

elytron with a large lateral blackish semi-denuded spot, and three costiform

lines along which the pubescence is more prominent, the recumbent pubes-

cence unusually long; erect hairs short and very sparse. Under surface dark

plumbeus, densely pubescent. Legs rather short and stout, throughout nearly

as in wilti, but with long flying hairs on the tibie, especially pronounced on

the posterior. Length 7.0 mm.; width 2.8 mm.

Texas (El Paso). Mr. Dunn.

This species in general appearance is intermediate between alpha

and wilti, but is not closely related to any other form, the long

flying hairs of the tibize being a very unusual character in Leiopus.

In the present arrangement of the species it may be placed just

after punctatus. ;

L. mimeticus n. sp.—Rather robust and convex; integuments rather

pale rufo-testaceous, the pubescence short, luteo-cinereous, scarcely at all .

variegated on the prothorax, the elytra with very minute sparsely placed

black fasciculate tufts, which are usually arranged in four or five rows on

each, and, in addition, with an elongate blackish semi-denuded spot at the

side, and an oblique black fasciculate and usually interrupted line near

posterior third. Head extremely minutely, moderately densely punctate ;

eyes separated above as in punctatus; antenne one-half longer than the body,

annulate with black at the apex of each joint as usual. Prothorax rather

short, three-fourths wider than long and four-fifths as wide as the elytra,

evenly convex and pubescent, not distinctly punctate, the lateral spine very

short and broad but not in the least rounded, situated just before basal third.

Elytra four-fifths longer than wide, the sides subparallel in basal two thirds,

then oblique to the apex, each elytron narrowly and obliquely sinuato-trun-

cate; disk coarsely, deeply punctate when denuded. Under surface very

finely, densely, uniformly pubescent. Legs short, maculate, the femora

strongly clavate; tibiz without long flying hairs; tarsi short and robust.

Length 4.5-6.5 mm.; width 1.8-2.6 mm.

Coleopterological Notices, ITT. 49

Texas; District of Columbia.

A small, robust and convex species, with unusually short, even

and pale pubescence, and bearing a striking resemblance to Lepto-

stylus biustus. It is rather closely related to Letopus crassulus,

from Lower California, but is well distinguished by its more elon-

gate and convex form, longer and denser pubescence, and especially

by the form of the elytral apices, which are here obliquely and

strongly truncate, but evenly rounded in crassulus. This species

has been described by Dr. Horn (Tr. Am. Ent. Soc., VIII, p. 125),

and somewhat doubtfully referred to L. crassulus, but I think that

the form of the elytral apices will conclusively distinguish them.

It is scarcely possible to divide our species of Leiopus generically

upon the presence or absence of fasciculate tufts on the elytra, and,

as there is but little difference in the degree of separation of the

middle coxe, the mesosternum being rather broad throughout, it

seems probable that all of our species will have to be assigned to

Hleothinus as recently defined by Mr. Bates, or, perhaps more

justly, the genus Sternidius Lec. should be revived for these species,

in which case Hleothinus would become synonymous.

VALENUWS n. gen.

Body oblong, depressed, minutely, sparsely pubescent and with long erect

sparsely placed flying hairs. Head vertical; front subquadrate, transverse,

finely carinate along the coriaceous support of the labrum; mandibles small ;

palpi slender, unequal, the terminal joints slender and gradually acuminate,

second joint of the labial robust, the third oblique and much narrower ; men-

tum small, transverse, very deeply inserted and inwardly oblique; eyes deeply

emarginate, moderately finely granulate; antenne inserted at the sides within

the ocular emarginations, widely distant at base, slender, minutely, rather

densely pubescent, the first three or four joints with a single series of short,

spinose sete beneath, scape long, slender, cylindrical, without trace of apical

cicatrix. Prothorax obliquely spinose at the sides behind. Elytra not cari-

nate at the sides. Anterior coxe not appreciably angulated externally, the

middle cavities distinctly open, narrowly separated. Legs slender; femora

feebly clavate ; tarsi short, robust, the basal joint of the posterior slightly

longer than the next two combined ; claws divaricate, small.

This genus belongs near Lepturges and is apparently still more

closely allied to the Central American Phrissolaus Bates, differing

from the latter in its much shorter antenne, depressed form, rounded

elytral apices and more normal abdominal structure, the fifth seg-

ment of the male being only as long as the two preceding together

and obtusely sinuate at apex.

50 Coleopterological Notices, IIT.

There is an element of uncertainty as to the proper position of

Valenus, however, owing to the fact that the only known represen- ~

tative is a male, but if the female proves to have an elongated fifth

seoment, it can only be compared with Astynomus, and from this it

departs widely in its spinose and not tuberculate prothorax.

V. inornatus n. sp.—Moderately robust, feebly shining, dark rufo-

testaceous above, much paler beneath, the color of the integuments not at all

concealed by the extremely minute, rather sparse and inconspicuous vesti-

ture, the long flying hairs of the elytra rigid and setiform. Head extremely

minutely, densely but feebly punctate; antenne about one-third longer than

the body, slender, the scape thicker but not at all clavate, as long as the next

two combined, joints three to eleven gradually decreasing in length. Pro-

thorax fully one-half wider than long, distinctly wider than the head and two-

thirds as wide as the elytra; base and apex transverse, the former distinctly

the narrower ; sides broadly arcuate anteriorly, obliquely and acutely spinose

at basal third, disk very unevenly and sparsely punctate, almost impunctate

toward the sides. Scutellum rather large, broadly rounded behind. lytra

parallel, the sides straight, three-fourths longer than wide, broadly rounded

behind, each elytron narrowly rounded at apex; disk coarsely and rather —

closely punctate toward base, the punctures becoming sparser and finer toward

apex; punctures bearing the flying hairs small and inconspicuous; surface

even. Under surface pruinose with dense, extremely minute pubescence.

Length 9.0 mm.; width 3.3 mm.

more irregular discal blotch at apical third, the pronotum with four

nearly as in aspersa. Prothorax acutely, obliquely spiculate at the

sides at basal fourth or fifth. Elytra twice as long as wide, in form

throughout nearly as in maculata. Legs pale testaceous throughout,

the tarsi alone darker. Length 4.7-6.5 mm.; width 1.8-2.4 mm.

G@zlitornia, Sta. Cruz Co.) ......-- 00-0. s0..00---- CALILOFMICA Nn. sp.

The species above identified as nigrella seems to be abundantly

distinct from maculata in its much longer male antenne, and from

aspersa in its more elongate prothorax and more finely and sparsely

punctate elytra, the sides of the latter being much more convergent

from base to apex in the male, and with more prominent and less

rounded humeri. In aspersa the three discal vitte of the elytra

are nearly always very distinct and generally conspicuous, and by

this characteristic it can be separated at once from the other species.

Anisopodus White is possibly synonymous with Hyperplatys, at

least the elongation of the posterior legs appears to be so gradual

as to cause great confusion in attempting to limit the former genus.

Differs greatly from the Mexican protensa and variegata in its

small equilateral scutellum, and from suffusa and phantasma in its

larger size and from the latter in addition in the absence of long

curved rigid sete. From the eastern stolata and Cuban grandis it

differs in its convex and not flattened elytral disk, and from the

Cuban jfilum in its non-sulcate elytra. The semi-denuded blotches

of the elytra are sparsely scattered, but slightly darker in color, and

are broad and very irregular and not linear as in séolata.

Although by the characters given, ovalis is brought very near to

plumbeus, it is really quite distinct in general appearance from this

and all the other species, being unusually short, oval and convex.

The material before me seems to indicate several closely allied

Species in the neighborhood of canaliculatus, one male, especially,

has the punctuation very sparse throughout, with the apical angles

of the prothorax not at all everted.

EPITRAGODES Cas.

This name was proposed (Ann. N. Y. Acad., V, p. 865) for the

species known as Lpitragus tomentosus Lec., the principal charac-

ters distinguishing it from Epitragus being the unexcavated meso-

sternum and the more or less seriate arrangement of the elytral

punctures. J have recently received another species, the two being

easily known by the following characters :—

Body rather densely pubescent, the pubescence unevenly marmorate.

tomentosus

Body glabrous, each puncture bearing an infinitesimal seta entirely concealed

Colorado Mr. W. Jiilich.

This species differs from delicatulus in its shorter, broader form,

coarser punctures and radically different punctuation of the elytra.

Several specimens.

EUSATTUS Lec.

The following form is not at all closely allied to any other thus

far described, but may be placed just after robustus in our lists :—

E. websteri n. sp.—Form and size nearly corresponding with the larger

specimens of reticulatus, black throughout, rather strongly convex, glabrous,

the pronotum dull and coarsely sericeous, the elytra somewhat shining. Head

coarsely, densely punctate, the punctures strongly coalescent and rugulose

behind; antennz subequal in length to the prothorax, the third joint equal

in length to the next two together. Prothorax nearly two and one-half times

as wide as the median length, the apex deeply emarginate, two-fifths as wide

which are acute and slightly prominent posteriorly ; sides strongly convergent

anteriorly and very feebly arcuate from basal third, thence to the base nearly

parallel and more arcuate; apical angles anteriorly produced far beyond the

eyes, but with the apex rounded; disk strongly convex, very broadly expla-

nate and reflexed at the sides, coarsely, deeply, extremely densely punctate

throughout, the punctures longitudinally confiuent, and, on the reflexed lateral

parts, becoming coarsely rugulose and confusedly confluent. Scutellum dis-

tinct, triangular. lytra twice as long as the prothorax, and, at base, equal

to the latter in width, in the middle very slightly wider, scarcely as long as

wide; apex very broadly parabolic; sides feebly arcuate; disk convex, almost

perpendicular toward the sides and apex; side margins throughout strongly

and unusually widely reflexed, each elytron with three strong acutely elevated

cost, which are more or less interrupted, and which do not attain the apical

angles, the suture not appreciably costate; intervals coarsely, sparsely and

confusedly punctate, evenly concave, each with a single median row of

subelongate distant tubercles. Epipleure very broad, occupying the entire

inflexed sides, strongly impressed near the sides especially toward base;

prosternum granulato-punctate, strongly impressed laterally throughout the

length, the hypomera strongly, broadly and abruptly oblique downwards.

Colorado.

The under surface is clothed very sparsely with short yellowish

hairs. One specimen.

I take pleasure in dedicating this species, perhaps the most inter-

esting of the novelties contained in the Levette cabinet, to Mr. F.

M. Webster, in partial recognition of many favors rendered by him

in connection with the transfer of the cabinet mentioned.

ELEODES Esch.

_ The following species, represented by a series of eleven specimens

from the Levette cabinet, is not closely allied to any other, but may

be placed for the present near humeralts :-—

E. rileyi n. sp.—Rather robust and convex, somewhat strongly shining,

intense black throughout. Head coarsely, rather closely punctate; antenneze

subequal in length to the head and prothorax, the third joint three times as

long as wide and rather longer than the next two combined, the outer joints

but moderately robust. Prothorar from one-fourth to three-fifths wider than

long, the apex broadly, feebly emarginate, distinctly narrower than the base,

the latter transverse, generally very broadly, feebly sinuate toward the middle ;

apical angles obtuse but not at all rounded, basal slightly obtuse, not much

rounded and rather prominent ; sides strongly arcuate at apical third, thence

strongly convergent and nearly straight to the apex, distinctly sinuate before

the base; disk rather coarsely, deeply punctate, densely so toward the sides,

sparsely and unevenly, with large impunctate patches toward the middle.

Elytra two and one-half times longer than the prothorax, and, in the middle,

from one-fifth to nearly one-half wider than the latter ; sides evenly arcuate ;

humeri narrowly rounded, slightly prominent and usually distinctly exposed ;

apex narrowly rounded; disk almost vertical behind, rather coarsely, feebly

and subasperately punctate, sometimes with very feebly impressed distant

lines, the punctures rather sparse, not much denser laterally, confusedly

disposed but often having a feeble lineal arrangement. Prosternum not at

all produced. Anterior tibial spurs extremely unequal, the anterior robust,

long, subparallel and truncate at apex, the posterior very small, acute, the

larger spur still more pronounced, broader and more truncate in the female.

Length 12.0-15.0 mm.; width 5.2-7.2 mm.

Arizona.

The anterior femora are completely unarmed in both sexes, and

the relative proportion in the length of the anterior tibial spurs is

nearly independent of sex, but both spurs are longer, and the ante-

rior much wider, more broadly truncate and more parallel in the

female than in the male.

From humeralis the present species differs in its smaller size,

Annas N. Y. Acap. Scr., VI, Nov. 1891.—5

much sparser punctuation, narrower, more convex form and much

shorter third antennal joint.

I have dedicated it to Prof. C. V. Riley of Washington, as a

slight token of my appreciation of his many acts of kindness and

liberality.

E. nitidus n. sp.—Rather slender, convex and subcylindrical, black

throughout and strongly shining, glabrous. Head rather sparsely punctate,

moderately coarsely so toward apex; antenne robust, nearly as long as the

head and prothorax, the third joint four times as long as wide and fully as

long as the next two together, last three joints distinctly dilated forming a

club, the ninth and tenth strongly transverse. Prothorax quadrate, very nearly

as long as wide, the apex transverse, broadly and feebly bisinuate, equal in

width to the base, which is broadly, rather strongly arcuate; apical angles

right, narrowly rounded, basal broadly obtuse and not prominent but not at

all rounded; sides parallel, very feebly arcuate; disk just visibly wider at

apical third than at base, evenly convex, extremely minutely and sparsely

punctate. S/ytra two and three-fourths times as long as the prothorax, and,

in the middle, nearly one-half wider, about twice as long as wide; sides

broadly arcuate ; base broadly emarginate ; humeri right, not noticeably ex-

posed ; apex acutely rounded ; disk obliquely declivous behind, having feebly

marked, distant, completely unimpressed series of extremely minute punc-

tures ; intervals minutely, sparsely and more or less confusedly punctate, the

punctures not distinctly larger or denser laterally. Femora all slender and

completely unarmed; spurs of the anterior tibize very unequal, the anterior

slender, acutely pointed and moderate in size; posterior tarsi slightly com-

pressed, nearly three-fourths as long as the tibie. Prosternum slightly pro-

longed but not at all reflexed, the apex vertical. Length 18.0 mm.; width

6.7 mm.

Arizona.

This species, which is represented before me by a single speci-

men, apparently a male, belongs near longicollis, but differs in its

flatter, rather shorter prothorax, less rounded on the sides, in its

shorter, broader elytra, broadly and rather strongly emarginate at

base and having widely distant rows of punctures, and in its shorter,

stouter and much more clavate antenne.

E. Compositus n. sp.—Moderately robust, convex, intense black

throughout, the pronotum dull and strongly alutaceous; elytra shining, very

feebly alutaceous, glabrous. Head densely dull, finely, rather sparsely punc-

tate; antenne rather long and stout, fully as long as the head and prothorax,

third joint between three and four times as long as wide, outer joints slightly

broader, the ninth and tenth somewhat transversely oval. Prothorar about

as long as wide, the apex and base equal in width, the former broadly, very

feebly emarginate, the latter correspondingly arcuate; apical angles right,

Coleopterological Notices, ITT. 59

slightly blunt, not prominent, the basal broadly obtuse; sides parallel, broadly

arcuate or subangulate just before the middle, very feebly sinuate just behind

the apical angles, feebly convergent and nearly straight to the base; disk

evenly convex, very minutely, sparsely punctate. lytra about two and two-

thirds times as long as the prothorax, and, in the middle, one-half wider than

the latter, about twice as long as wide; sides broadly arcuate; humeri not at

all exposed ; apex acutely angulate; disk strongly declivous behind, deeply

sulcate, the ridges strongly convex and shining, each with a single rather

uneven Series of small, moderately distant punctures, the intervals as wide as

the ridges, deep, opaque, each with a single series of rather small, close-set,

asperate punctures. Legs slender, the femora shining, rather finely but

strongly punctate, the anterior alone with a strong acute tooth near the

apex; tibize strongly rugose except toward base, the spurs of the anterior

small, acute and nearly equal. Prosternum with the apex slightly reflexed,

acute and tuberculiform. Length 16.0 mm.; width 6.6 mm.

Texas.

A single specimen from the Levette cabinet. This species has

but little affinity with any other thus far described, the prothorax

being nearly similar to that of genizlzs and the elytra deeply sulcate,

as in the typical hispilabris; for the present it may be placed just

after the latter in our lists.

EULABIS Esch.

The species of this genus may be distinguished as follows :—

Pronotum bicarinate; body glabrous ..........scsseccsceesesseeeeeees DECAPINAtTA

The last of these was placed in a separate genus by LeConte, and

possibly Epantius should be regarded as valid, or at least a good

subgenus.

E. laticornis n. sp.—Moderately robust, subparallel, somewhat de-

pressed, glabrous, black to piceous-black ; legs paler, rufo-piceous ; antenne

black ; integuments dull. Head coarsely, densely punctate, the punctures

finer, less crowded and more asperate anteriorly ; epistoma transversely trun-

cate ; eyes short and transverse but only one-half divided ; antenne unusually

long, almost attaining the base of the prothorax, extremely stout, the outer

joints strongly transverse and compressed. /Prothorax one-fifth to one-fourth

wider than long, the apex transversely truncate, rather distinctly wider than

the base, the latter extremely feebly arcuate ; apical angles very obtuse, dis-

tinctly rounded, basal widely obtuse but not rounded and generally minutely

prominent; sides broadly, evenly arcuate, more convergent and straighter

toward base; disk widest before the middle, evenly, very feebly convex,

coarsely, deeply, extremely densely punctate, the punctures having much less

tendency to longitudinal coalescence than in crassicornis. lytra one-half

longer than wide, oblong-oval, about twice as long as the prothorax, and, in

the middle, about one-fourth wider than the latter, abruptly, obtusely rounded

at apex; sides broadly arcuate; humeri narrowly rounded, somewhat tuber-

culiform and prominent and distinctly exposed ; base broadly, feebly emargi- —

nate, the basal margin unevenly tumid; disk broadly flat above, the cost

strongly marked; intervals each with a single row of coarse deep circular

punctures. Abdomen densely, coarsely and deeply punctate, each puncture

bearing a distinct recumbent hair; median portions broadly impressed or

flattened. Legs very stout and moderately long, the hind femora much longer

than the intermediate ; anterior tibie slightly arcuate, stout. Length 9.2-10.0

mm.; width 3.8—4.2 mm.

California (San Diego).

One of the two specimens before me formed part of the Levette

cabinet, the other was kindly communicated by my friend Dr. F.

K. Blaisdell, and was collected at Poway.

This species is quite distinct from any other thus far known; it

is nearly as large as grossa, but has less inflated elvtra. It may

be readily distinguished from crassicornis by its more robust and

especially much longer antenne, much larger size, more depressed

form, coarser punctuation and scarcely at all longitudinally rugulose

sculpture of the pronotum.

C. levigata n. sp.—Moderately robust and convex, intense black

throughout, glabrous. Head rather coarsely, densely punctate behind, much

more finely so on the epistoma; sides broadly reflexed before the eyes;

antenne rather short and slender, about as long as the prothorax, rufescent

at base, the third joint distinctly shorter than the next two together. Pro-

thorax nearly twice as wide as the head, two-fifths wider than long, the apex

and base subequal, the former truncate, feebly sinuate laterally, the latter

broadly, feebly arcuate ; sides broadly, evenly arcuate, becoming oblique and

straight near the basal angles, which are very obtuse but not rounded ; apical

angles slightly obtuse and narrowly rounded; disk feebly alutaceous in lustre,

evenly convex, rather finely, sparsely punctate throughout, the punctures

becoming almost obliterated near the thick marginal bead. Scutellum broad,

triangular. lytra two-thirds longer than wide, two and one-half times as

long as the prothorax, and in the middle, one-fourth wider than the latter ;

sides nearly straight and parallel from the strongly oblique and broadly

arcuate humeri to posterior third, the apex rather acutely triangular; disk

rather strongly, gradually declivous behind, with scarcely at all impressed,

distant strie of small, unevenly spaced and feeble punctures, the intervals

shining, coarsely wrinkled, extremely minutely and sparsely punctate, without

small tubercles except near the sides toward apex. Jegs short and slender.

Length 13.0 mm. ; width 5.6 mm.

California (Sta. Barbara). Mr. G. W. Dunn.

This species differs from blaschkei in its shorter, broader form,

smooth surface, finely, rather sparsely punctate prothorax with the

sides behind oblique and straight and not at all sinuate before the

broadly obtuse basal angles, and in the much smoother and less

tuberculate elytra. In general appearance it is altogether distinct

from either blaschkei or bachet. A single specimen.

ALAEPHUS Horn.

A. macilentus »n. sp.—Elongate-oval, moderately convex, pale luteo-

flavate throughout, strongly shining, the head and pronotum very slightly

alutaceous ; body nearly glabrous, each puncture of the elytra bearing a

short pale recumbent seta. Head rather coarsely punctate, the punctures

shallow, strongly and polygonally crowded forming a reticulation of raised

lines ; eyes large, angulate antero-internally ; front deeply impressed at each

side in front of the eyes; antenne slender, cylindrical, filiform, a little longer

than the head and prothorax, the outer joints not thicker but gradually much

shorter, third very long and slender, though scarcely as long as the next two

together. Prothorax but very slightly wider than long, the apex transversely

truncate, nearly three-fourths as wide as the base, the latter transverse, very

broadly, feebly bisinuate; basal angles right, not rounded, the apical very

obtuse and rather blunt; sides broadly, feebly, almost evenly arcuate; disk

scarcely as wide at base as just behind the middle, feebly convex, broadly,

feebly impressed along the middle, feebly, rather widely reflexo-explanate

laterally, especially toward base, very feebly, subcoalescently punctate and

minutely subrugulose. Scutellum distinct, broadly rounded or subangulate

behind and constricted at the sides near the base. lytra about three times

as long as the prothorax, and, in the middle, about one-third wider than the

latter, a little more than twice as long as wide; sides broadly arcuate; apex

gradually, acutely ogival; humeri broadly rounded, a little broader than the

base of the prothorax; disk evenly convex, finely but rather strongly, evenly

but irregularly, moderately densely punctate. Abdomen finely, sparsely

punctate. Legs moderate in length, slender. Length 5.0-6.4 mm.; width

1.7-2.2 mm.

Arizona; New Mexico.

Distinguishable from pallidus by its much smaller size and more

slender form, more quadrate prothorax, still paler coloration and

more shining surface lustre. Apparently not rare.

IDIOBATES 2. gen.

This name is proposed for Tenebrio castaneus Knoch, an anoma-

lous form hitherto associated with the normal members of Tenebrio,

but manifestly distinct by reason of its completely divided eyes and

abdominal structure, only the penultimate segment of the latter

being provided with a visible coriaceous hind margin. I would

suggest that it be placed in the Blapstini near Mecysmus.

The generic value of castaneus was long ago recognized by

Bates, and later by LeConte, but I am not aware that it has ever

been given a distinctive name. It certainly constitutes as good a

connective bond, between the Blapstini by way of Mecysmus and

the other Tenebrionini through ‘Tenebrio, as could well be found,

the undilated anterior tarsi being a matter of no material import-

ance in this connection.

In the table of the tribe Tenebrionini given on page 393, Vol. V

of these Annals, the genus Calcar, together with one or two other

exotic genera, must constitute a group distinct from the Tenebriones

by reason of the very exceptional abdominal structure, the coria-

ceous hind margins of both the third and fourth segments being

completely invisible. This well-known fact was inadvertently over-

looked in compiling the table alluded to.

BLAPSTINUWS Latr.

I have recently, by way of experiment, dissected a series of eight

specimens of a form very near rufipes, probably a variety or race of

that species, and have found a singular and altogether unexpected

Coleopterological Notices, IIT. 63

constancy in the form and size of the rudimentary hind wing, the

extreme variation not amounting to more than one-fifth of the

average length, the latter being a little more than one-half the total

length of the elytra. This is not put forward as proof of any

general rule, but simply as an isolated fact in a field very little

explored and still less understood.

It seems extremely difficult to account for this constancy by the

theory of natural selection, and, as it is impossible to doubt the

ever-acting reality of the principle in question, we can only infer

that rudimentary organs are not necessarily inordinately variable,

and, when comparatively constant, that the standard is maintained

by the action of other laws less easily appreciated.

Darwin, in his ‘‘ Natural Selection,” dwells but briefly upon this

question, but gives as one instance of variability in rudimentary

organs, the wings of a certain beetle which may be either fully

developed or more or less rudimentary. Other authors have also

cited examples of a corresponding nature. I think, however, that

there is more or less doubt to be attached to this entire category of

observations, due to a lack of knowledge of the physical conditions

under which the various specimens may have existed. It would for

example be manifestly repugnant to the fundamental idea of natural

selection to imagine individuals of the same species, with fully

developed and rudimentary wings living together on the same

bush—except in cases of sexual dimorphism, which constitute a

wholly different branch of the subject,—for this very principle

would tend to eliminate those individuals which were least able to

maintain themselves, and we cannot assume that perfectly and

partially developed wings constitute conditions equally fitting the

Species to maintain itself against a great variety of external influ-

ences. | |

The only conceivable circumstances under which individuals of a

wingless species may, under the same conditions, also be found with

more or less developed wings, are due to occasional reversion to the

conditions characterizing the primitive stock from which the species

may have been derived. If the species has been differentiated for

a comparatively great length of time, which may perhaps be judged

of approximately by its degree of departure from related winged

species, this reversion will surely be quite exceptional.

Wingless species occurring on oceanic islands are frequently said

to be identical with continental fully winged forms, but it seems as

64 Coleopterological Notices, IT.

though the mere fact that one form is winged and the other wing-

less ought to be sufficient ground for specific isolation, especially as

it is highly probable that the more or less extended time necessary

to bring the winged continental form to the wingless insular condi-

tion, will generally be sufficient to develop other specific differences

At all events the wingless island form must always be considered

an incipient species or variety, for this kind of isolation has been one

of the most potent factors in the differentiation of species as we now

understand them.

CONIBIOSOMA Cas.

The following species bears but little external resemblance to

elongata, but as the prothorax is strongly fimbriate, the body appa-

rently apterous, and the anterior tibiz slender, it must either be

placed here or in a new genus :—

C. laciniata n. sp.—Moderately slender, oblong-suboval, densely punc-

tate anteriorly but rather shining; body black throughout, the legs rufous,

the antenne dark piceo-rufous; pubescence rather dense, moderately long,

nearly as in Blapstinus, very coarse, rigid, semi-erect and black, not very

conspicuous. Head short and broad, broadly, feebly sinuate at apex, rather

coarsely, very densely and deeply punctate ; eyes moderately large, the upper

lobe elliptical ; antennz long, about as long as the head and prothorax, stout,

clothed throughout with long stiff black sete, the outer joints gradually, feebly

incrassate and distinctly transverse, the eleventh narrower than the tenth,

the third long, equalling the next two combined. Prothorax about one-third

wider than long, the apex as wide as the base, transversely truncate, the base

broadly arcuate, not appreciably sinuate toward the basal angles which are

obtuse but not rounded; apical slightly obtuse, not rounded ; sides broadly,

almost evenly arcuate; disk widest near the middle, evenly convex, rather

coarsely, very deeply and extremely densely punctate throughout, the side

margins with a dense fringe of long erect stiff sete. Scutellum triangular,

entering the disk of the elytra, densely punctate. lytra about two and one-

half times as long as the prothorax, and, in the middle, nearly one-fourth

wider than the latter, fully three-fourths longer than wide, obtusely para-

bolic at apex ; sides parallel, very feebly arcuate ; humeri slightly exposed at

base; disk with rather coarse, feebly impressed series of somewhat coarse,

deep, moderately close-set punctures, the intervals feebly convex, shining,

extremely minutely, rather sparsely and confusedly punctate. Abdomen rather

finely, but deeply and densely punctate, broadly, deeply impressed in the

middle in the male. Legs rather slender, the hind tarsi with the basal joint

subequal to the next two and very much shorter than the last. Length 4.6-5.0

mm.; width 1.8—2.1 mm.

Coleopterological Notices, ILI. 65

Arizona (Tucson). Mr. H. F. Wickham.

This exceedingly interesting and aberrant species is easily recog-

nizable by its rather long antennz, conspicuous pronotal fringe and

coarse black vestiture ; it will probably have to be ultimately sepa-

rated from elongata as a distinct genus.

PALEMBUS 1. gen.

I have applied this name to a small species, having very nearly

the antennal structure of Oplocephala Lap. (= Hvoplus Lec.), and

apparently allied to that genus, but differing in its narrower, more

depressed form, non-tuberculate head, large coarsely faceted eyes,

longer hind tarsi and entire epipleure ; its general characters are as

follows :—

Body parallel, rather strongly convex. Head rather short and broad, the

eyes large, more prominent than the sides before them; antenne short, the

last seven joints short and transverse, forming a long loose parallel club;

maxillary palpi rather slender, the last joint elongate-oval, about as long as

the preceding two together, the apex obliquely and narrowly truncate;

mentum obtrapezoidal; ligula large, corneous, the connate paraglosse large,

broadly rounded. Prothorax transverse, the prosternum moderately wide

between the coxe. Elytra striate; epipleure narrow, entire, flat. Legs

rather slender, the anterior tibie not dilated; posterior tarsi long, but

slightly shorter than the tibie, the basal joint equal to the last and as long

as the second and third together, the third one-half longer than wide.

In the type specimen the structure of the middle coxal cavities

cannot be clearly discerned.

I owe the above-described specimen to the kindness of Mr. W.

Jiilich, in whose cabinet there is a considerable series, displaying

scarcely any variation.

RUES n. gen.

This name is proposed for a distinct genus belonging near Hege-

mona Cast., and represented by the species recently described by

me under the name Helops ovipennis (Ann. N. Y. Acad., V, p. 487).

It resembles Hegemona in the unusually wide mesosternum,

nearly flat between the coxe, and in the exceedingly short meta-

sternum, but differs in the wider elytra, extremely broad epipleure

and very short slender legs.

HELOPS Fab.

Both of the following species are related to bachez, and should

immediately follow that species in our lists :—

H. blaisdelli n. sp.—Oblong-oval, rather strongly convex, piceous-

black, the elytra castaneous ; antennz and legs throughout rufo-testaceous ;

integuments glabrous and strongly shining. Head feebly convex, rather

coarsely, deeply, moderately densely punctate, the punctures longitudinally

coalescent, forming long furrows and ruge; eyes prominent and convex;

antenne slender, filiform, nearly one-half as long as the body, joints four to

ten elongate, evenly obconical, subequal, eleventh a little longer, third much

longer. Prothorax transverse, one-half wider than long and four-fifths wider

than the head; base and apex subequal and both transversely truncate; sides

strongly and almost evenly arcuate; apical angles broadly obtuse and nar-

rowly rounded, basal very obtuse but scarcely rounded; marginal bead very

fine and feebly developed throughout the length; disk very much wider at

basal third than at base, evenly convex, somewhat coarsely, deeply, rather

densely and unevenly punctate throughout, the punctures but slightly sparser

toward the middle, toward the sides more or less longitudinally coalescent in

twos or threes. Scutellum broadly ogival. lytra two and one-half times as

long as the prothorax and not in the least wider than the latter in any part,

four-fifths longer than wide; sides parallel and nearly straight ; apex obtusely

ogival; humeri rather broadly exposed at base, slightly obtuse, narrowly

rounded; disk rather finely striate, the strie entire, not impressed but

abruptly grooved, the punctures elongate, moderate but uneven in size and

mutual separation ; intervals flat, feebly and confusedly undulated, finely, not

Coleopterological Notices, ITT. 67

very densely punctate, laterally toward the apex with small, distant, feebly

elevated tubercles in single series on each. Abdomen finely, somewhat densely

punctate; metasternum but slightly shorter than the first ventral segment ;

mesosternum long and depressed in front, rather narrowly separating the

coxe, feebly declivous and slightly impressed before the coxe, the process be-

coming horizontal behind ; prosternal process not at all prominent posteriorly.

Legs moderately long, the tibie rather strongly enlarged from base to apex,

the anterior tarsi rather broadly dilated in the male, posterior short with the

basal joint equal to the next two and much shorter than the last. Length

8.0-9.0 mm.; width 3.2-3.3 mm.

California (San Diego). Dr. F. E. Blaisdell.

The two specimens before me are both males, and have the intro-

mittent organ rather broad throughout, abruptly and sharply acumi-

nate at apex, and with the upper surface deeply and longitudinally

excavated, the excavation extending almost to the apex; in bachet

it is finely but less abruptly acuminate, and the upper surface is

finely, longitudinally subcarinate near the apex, the excavation

being very feeble and much less apical. The form of blaisdelli is

considerably shorter and the prothorax is very much more trans-

verse.

H. discipula n. sp.—Evenly elongate-oval, strongly convex, glabrous,

moderately shining, the elytra alutaceous; upper surface dark castaneous,

beneath paler, rufescent; legs and antenne rufous. Head coarsely, not

densely punctate, the punctures scarcely at all longitudinally confluent,

slightly finer anteriorly ; eyes prominent; antenne short, but slightly longer

than the head and prothorax, joints four to eight increasing in length, rather

slender, obconical, nine to eleven thence gradually shorter and more dilated,

the last obliquely oval and not longer than the tenth, third one-half longer

than the fourth. Prothorax nearly one-half wider than long, the apex rather

distinctly narrower than the base, both subtruncate or extremely feebly arcu-

ate; sides strongly evenly arcuate; apical angles broadly obtuse and slightly

rounded, basal extremely obtuse and widely rounded; marginal bead very

fine but distinct throughout the length; disk not very coarsely, rather densely

punctate, the punctures sparser in the middle, with scarcely any tendency to

coalesce longitudinally toward the sides. Scutellum broadly triangular, short,

coarsely, rather densely punctate. lytra oblong-oval, about three times as

long as the prothorax, and, in the middle nearly one-third wider than the

latter, twice as long as wide, gradually ogival behind ; sides parallel, broadly

arcuate; humeri obtuse, exposed at base; disk with very fine, entire unim-

pressed series of fine unevenly spaced and generally more or less linear punc-

tures, the intervals flat, minutely, sparsely, confusedly punctate, each with a

single widely spaced series of very small tubercles, which are rather indistinct

toward the suture. Abdomen finely, sparsely punctate; sterna nearly as in

blaisdelli. Legs rather long, very slender. Length 7.0 mm.; width 2.9 mm.

68 Coleopterological Notices, ILI.

California (probably near San Diego). Mr. W. Jiilich.

The type is apparently a female, and the anterior tarsi are not

dilated. It is easily distinguishable from both bachei and blaisdelli

by the short antenne and broader elytra, and from the former, in

addition, by its short transverse prothorax with fine marginal bead.

H. cylindriformis n. sp.—Narrow, strongly convex, subcylindrical,

black throughout, shining and feebly alutaceous. Head scarcely as long as

wide, broadly, evenly, feebly emarginate at apex, the surface rather finely and

densely, very strongly punctate; eyes rather more prominent than the feebly

reflexed sides before them; antenne slender about one-half as long as the

body (male) or scarcely as long as the head and prothorax (female), third

joint a little longer than the next two together, outer joints gradually and

only slightly broader, the tenth about one-half longer than wide and a little

shorter than the eleventh, the latter slightly longer in the male where it is

twice as long as wide, obliquely acute at apex. Prothorax elongate, fully as

long as wide, the apex broadly arcuate, a little narrower than the base, the

latter subtruncate ; sides broadly arcuate at or just before the middle, feebly

convergent and more feebly arcuate to the apex, broadly, distinctly sinuate

before the basal angles which are right, not at all rounded and somewhat

prominent; disk evenly convex, finely, densely punctate, the punctures strong

and always distinctly separated, but slightly less dense toward the middle

where there is usually a narrow uneven impunctate line. lytra twice as

long as wide, not quite three times as long as the prothorax, and, in the

middle, scarcely two-fifths wider than the latter; sides parallel, broadly,

feebly, evenly arcuate ; apex obtusely ogival ; humeri completly obsolete, the

base exactly equal to the thoracic base; disk with unimpressed series of small

unevenly spaced but generally approximate and slightly elongate punctures,

the intervals flat, very finely, irregularly, sparsely punctate. Abdomen very

finely, rather sparsely punctate. Legs slender, the anterior tarsi very slightly

dilated in the male. Length 9.0-14.0 mm.; width 3.2-5.0 mm.

New Mexico (Fort Wingate). Dr. Shufeldt. .

This species, which is represented by a series of eight specimens,

is allied to dzffictlis, but differs in its more slender subcylindrical

form, much more elongate prothorax with less blunt apical angles,

narrower and more finely and sparsely punctate elytra and rather

shorter antenne.

HT viridimicans Horn appears to be homologous with the Cuban

rufipes, and to be more appropriately assignable to Nautes than to

Helops, although it must be confessed that the difference between

these genera has not been very satisfactorily expressed.

H. montana Lec. is quite distinct from conveaxula in its broader,

more oblong form, and in its longer and much stouter antenne

and notably larger size.

Coleopterological Notices, ITT. 69

STRONGYLIUM Kirby.

Two specimens of S. atrum Champ., from the Levette cabinet and

labeled ‘‘ Arizona” are before me. This species is quite aberrant in

appearance and may be known at once by its large size, smooth but

dull surface, rather coarse, very dense pronotal punctuation and

fine unimpressed and feebly punctate elytral striz.

CISTELID.

There is probably no family, even of the Heteromera, where the

differentiation of genera depends so little upon definite and constant

modifications of special organs, and so greatly upon general habitus,

as in the Cistelidze. There are, for example, but few special char-

acters relating to the palpi, tarsal lobes, eyes or antenne, which

remain invariable throughout the limits of even those genera which,

in the majority of species, are particularly distinguished by important

developments or modifications of any one of the organs mentioned.

We are therefore beset with numerous difficulties in our definition

and limitation of the genera.

‘In regard to the family considered in its entirety, however, the

case is quite different, since there is no group of the Heteromera

which is so homogeneous within itself, or so clearly limited in

extent. For, while closely related to the Tenebrionide through

Strongylium and other allied genera, it is always and invariably

distinguishable by the pectination of the tarsal claws; besides this

there is, in the vast majority of genera, a marked and unmistakable

peculiarity of facies which can seldom be mistaken.

The porous system of the antenne is developed to an extent

unknown in the Tenebrionide, except in certain of the strongyliide

genera, the entire surface of all but three or four of the basal joints

being studded with large circular sparsely placed pits, which are

filled with a white sensitive material of a spongy-pubescent nature.

These pores are frequently so large as to be quite conspicuous under

the lowest powers of amplification.

The Cistelide resemble the lower Tenebrionide in the prolonga-

tion backward at the sides of the third and fourth ventral segments,

which is however more marked and general than in the latter family,

and also in the well-developed coriaceous posterior margin of these

70 Coleopterological Notices, ILI.

segments; also in the thinner integuments of the body, with soft

and easily ruptured connective tissues. Perhaps some of the char-

acters which the family in general possesses in common with the

. Strongyliini, indicate really a higher development than that of the

Asidine and Tentyriine; the superior powers of perception indi-

cated by the complex porous system of the antenne, large eyes and

more developed palpi, would, at any rate, seemingly point to this

conclusion.

As more important distinctive characters of the family, it may be

said that the antenne and tarsi are usually long and slender, the

basal joint of the posterior tarsi being more or less elongate. The

anterior cox are narrowly separated, the cavities always closed

behind but never confluent, at least externally, although sometimes

separated by a very thin lamina; beneath this lamina they may

possibly sometimes be confluent, but usually appear to be separated

by a more or less thickened membrane. The eyes are generally

large, sometimes extremely so. The mandibles are small or moder-

ate, arcuate and finely notched at apex, occasionally being nearly

entire, but this character cannot be advantageously employed in

classification, except in distinguishing closely allied genera. The

genera with lobed tarsi appear, as a rule, to be more constant in

generic as well as specific characters, than those with simple tarsi.

The sexual characters of the male are generally strongly mani-

fested in the eyes, antenne or genital apparatus. The intromittent

organ is more or less acutely pointed at apex, the under side being

channeled, except very near the apex. Lying in this groove is a

curious straight spike hinged at one end to a point of attachment

within the channel, which can be placed in a position perpendicular to

the organ, and which probably locks the organ securely to the inner

surface of the vagina. The strong hold thus obtained, is often

abundantly evident by the great extrusion of the female viscera in

specimens captured in copula. It is quite singular that this spike

is not exhibited in any of the many elaborate and apparently care-

ful drawings of Mr. Saunders published in the Biologia; it is often

plainly visible, projecting from the under surface of the penis in

Hymenorus.

The abdomen consists of five segments in both sexes. ~ The

cedeagus proper is protected by a plate which is often extruded

beyond but usually concealed beneath the fifth segment, the plate

being sometimes quite prominent behind in one or both sexes accord-

ing to the genus;' it is generally deeply bilobed in the male and

more or less truncate in the female, but may occasionally be com-

pletely non-lobed in the male. Under the latter circumstances it

has much the appearance of an additional segment, and is often

designated the ‘‘sixth segment.”” It is, however, not a segment in

any such meaning as is attached to the other abdominal segments,

but is a part of the genital apparatus, and should more properly be

termed the ‘genital armature.”? It probably serves no other pur-

pose than a guide or protection to the cedeagus proper, the lobes of

the male not constituting in any sense a clasping or locking organ.

In view of the intricate affinities of the various genera and the

complex, extremely prominent and greatly diversified sexual modi-

fications of the antenna, palpi, eyes, tarsi, fifth ventral segment and

genital armature in the various species composing them, a general

and exhaustive study of the Cistelidze would undoubtedly prove

one of the most instructive but, at the same time, one of the most

laborious works which could well be undertaken. In the absence

of a sufficiently general knowledge of the family, I feel therefore,

that the characters employed in the following table will, in many

cases at least, be ultimately found to possess far less value than

would, with the comparatively limited material at my service,

appear to belong to them. However, as represented in our fauna

the genera may for the present be distinguished by the following

characters :’—

1 The group ‘‘Cténiopides’’ of Lacordaire will probably not prove to be

entirely natural, and as there are extremely few genera—Andrimus (Cteniopus

Lec.), and possibly Androchirus—within our faunal limits ,which can be

placed within it, I have disregarded it in the generic scheme which is here

presented. A division into distinct groups, based upon the protrusion of the

genital armature in both sexes, would give rise to difficulties analogous to

those encountered in attempting to divide Mycetophila into distinct genera

on certain prosternal characters, a statement of which will be given more fuliy

under that genus.

2 I have been greatly aided in this investigation by material placed in my

care by Prof. C. V. Riley and Mr. W. Jiilich, and also have to acknowledge

my indebtedness to Mr. Champion for typical representatives of many of the

Central American forms, which have been extremely useful in many cases

besides that of proving the equality of Prostenus californicus and Xystropus

Sulgidus.

XYSTROPUS Sol.

Prostenus Horn nec Latr.

The head in Xystropus is almost of the same form as in Helops

and some other allied genera of Tenebrionide ; in Stenochidus it is

of a more strictly cistelide type, but still the general form of body

recalls the Tenebrionide much more forcibly than any of the typi-

cally cistelide genera which follow. In fact there seems to be some

decided coordination between the form of the abdominal process

and relationship with the Tenebrionide. This is my reason there-

fore for placing Xystropus and its allies first instead of last in the

series.

In Xystropus as represented by califurnicus, the eyes are small,

short and strongly transverse, the antenne moderate in length,

stout, incrassate and compressed, the maxillary palpi moderate, with

the apex of the fourth joint but moderately oblique and the angle

at the base much less than right, resembling somewhat that of

Helops californicus. The prosternal process is horizontal poste-

riorly, then abruptly vertical to the level of the prosternal side-

pieces, where it becomes strongly dilated, widely separating the

latter at the posterior margin; the hind coxe are distinctly sepa-

rated by a rounded abdominal projection. The legs are short, the

tarsi without lobes, clothed beneath with long coarse hair, and with

the basal joint of the posterior unusually short. The ungues are

Annas N. Y. Acap. Sc1., VI, Nov. 1891.—6

T4 Coleopterological Notices, ITT.

moderate in length, the outer contour almost evenly arcuate, the

apex finely and acutely produced beyond the pectinate portion, the

latter extending nearly to the base, the denticles fine, long and spini-

form, gradually becoming very short toward base, eight or nine in

number.

The single tropical species which extends within our faunal limits

may be described as follows :'—

X. californicus Horn.—Trans. Am. Ent. Soc., 1867, p. 138 (Prostenus) ;

fulgidus Makl.: Act. Soc. Fenn., X, p. 680.—Oblong-oval, evenly, moderately

convex, polished throughout, the upper surface metallic red, the under black

with steel-blue reflection ; legs and antenne black throughout; integuments

devoid of .fine pubescence, the upper surface bristling with long erect sete

from the coarse punctures. Head coarsely, very sparsely punctured, the eyes

small; antenne one-half as long as the body, very stout, compressed, feebly

attenuate through the last three joints, the ninth joint as wide as long, third

distinctly longer than the fourth. Prothorax transversely oval, but little more

than one-third wider than long, the sides feebly angulate at basal third; disk

without trace of impression or basal fovee, extremely coarsely, sparsely and

unevenly punctate, the large circular punctures intermingled with smaller

ones. Llytra between three and four times as long as the prothorax, and, in

the middle, about two-fifths wider, acutely parabolic at apex, the sides feebly

arcuate, the humeri rather narrowly rounded and broadly exposed, the disk

with unimpressed series of rather coarse close-set punctures; the intervals

each with a single series of widely distant punctures, which are very much

larger than those of the strie. Abdomen finely, sparsely punctured. Legs

short, slender, the tarsi somewhat compressed, short, the basal joint of the

posterior but slightly longer than the next two combined. Length 9.3 mm. ;

width 3.5 mm.

California; Mexico; Panama; Colombia.

The representative from Panama, sent me by Mr. Champion, is

precisely similar in every detail to the single specimen of Prostenus

californicus in the LeConte cabinet at the Cambridge Museum.

This indicates a distribution which certainly could not have been

anticipated from analogy, at least in the present family.

LYSTRONICHUS Latr.

A comparatively composite genus in its present scope, essentially

tropical in distribution, but extending to the extreme southern

limits of the United States.

pendicular to the middle point of the interocular surface.

Coleopterological Notices, ITI. T5

But one species has been described from our fauna, although two

are said to be known from Texas.

L. piliferus Champ.—Biol. Cent.-Amer., Coleopt., IV, Pt. i, Nov. 1888,

p. 462.

I have not seen any representative of this species. It is proba-

ble, however, from the remarks made by Mr. Champion, that it

will ultimately have to be separated from the more typical forms of

the genus.

It is ‘“‘oblong-ovate, feebly convex, obscure reddish-brown, opaque,

above usually of a pruinose bluish-violet, obscure purplish, or green-

ish-bronzy tint, the surface somewhat thickly clothed with long erect

hairs, and also sparsely pubescent.”” The antenne are ‘‘very long,

slender and filiform,” and the elytra have ‘‘rows of very minute

punctures placed upon obsolete strie.” Length 6.0-8.3 mm.; width

2.0-3.5 mm.

STENOCHIDUS Lec.

In this genus the posterior coxe are moderately separated by a

Short abdominal projection, which is evenly rounded at apex and

quite similar to that of Xystropus, the anterior being separated by

a rather wide, longitudinally convex prosternal process, which is

strongly declivous and gradually attenuate behind. ‘The legs are

long and slender, the penultimate joint of all the tarsi strongly

lobed beneath, the antepenultimate joint of the anterior and inter-

mediate also lobed but less strongly, that of the posterior simple ;

these modifications are independent of sex.

The mandibles are distinctly notched at apex, the two lobes sub-

equal. The fourth joint of the maxillary palpi is elongate, more or

less recti-triangular, and differs sexually in form as described below

under S. gracilis; the last joint of the labial is short and robust,

wider than long, with the inner side slightly shorter than the outer.

The ungues are moderate in size, the external outline more arcuate

near the apex, the latter being finely and acutely produced beyond

the pectination, which is long and rather fine, the denticles six or

seven in number.

The general form of the body is elongate and convex, the pro-

thorax subcylindrical, the integuments being more or less strongly

granulato-reticulate and completely glabrous. The wings are well

developed.

76 Coleopterological Notices, III.

Stenochidus seems more closely related to Narses Champ. than

to any of the other Central American genera, but the general aspect

of the species must be quite different. Our species are only two in

number and may be thus distinguished :— :

Very dull, the legs black, with the basal three-fourths of the femora red.

gracilis

More shining, the elytral punctuation more distinct; legs black throughout.

cyanescens

S. gracilis Lec.—Ann. Lye. N.Y., V, 1851, p. 150.—Oblong, subparallel,

strongly convex, black, the elytra sometimes with a bluish tinge, the basal

three-fourths of the femora red; upper surface throughout very dull and

strongly reticulato-granulose. Head and pronotum somewhat coarsely, very

densely punctate; eyes small; antenne long and slender, gradually incras-

sate. Prothorax quadrate (male) or very slightly transverse (female), the apex

transversely truncate, almost as wide as the base, the latter very feebly bi-.

sinuate; basal angles slightly obtuse and quite distinctly blunt; sides nearly

parallel and feebly arcuate, slightly more convergent near the apex; disk

feebly, cylindrically convex, not impressed ; fovee obsolete. lytra three and

one-half times as long as. the prothorax and nearly one-half wider, rather

abruptly, obtusely ogival in apical third; sides nearly straight, parallel ;

humeri narrowly rounded and broadly exposed at base; disk with fine,

minutely punctate strie; intervals not distinctly punctate. Abdomen more

shining, finely, sparsely punctate. Legs very long and slender, the hind tarsi

much shorter than the tibiw, with the basal joint distinctly longer than the

remainder. ;

Male.—EHyes separated by two-thirds more than their own width; antennz

two-thirds as long as the body, slender, feebly inerassate, the ninth joint fully

twice as long as wide; maxillary palpi with the fourth joint rather more than

twice as long as wide, the angle at the support distinctly more than right, the

apex a little longer than the outer side; abdominal punctures strong, becom-

ing closer toward apex, the fifth segment entire at apex, with the surface

broadly feebly impressed along the middle. :

Female.—Kyes separated by fully twice their width ; antenne one-half as long

as the body, gradually, rather strongly incrassate, the ninth joint obconical,

one-half longer than wide; fourth palpal joint recti-triangular, twice as long as

wide, the apex not at all longer than the outer side; abdomen very minutely,

feebly, sparsely and evenly punctate throughout.

Length 7.0-8.0 mm.; width 2.3-2.9 mm.

California (Santa Cruz and San Diego Cos.).

feebly so in the male, and the third and fourth antennal joints are

equal in both sexes. The male is generally distinctly more slender

than the female.

Coleopterological Notices, ITT. Te

S. cyamescens Lec.—Proc. Ac. Phila., 1859, p. 78.—Elongate, the body,

legs and antenne throughout black, rather strongly shining. Head rather

coarsely, densely punctate. Prothorax but slightly wider than long, nearly as

in gracilis but more finely, not so densely punctate, the punctures all narrowly

separated. lytra four times as long as the prothorax in the male, distinctly

shorter in the female, one-third wider than the latter, the humeri narrowly

rounded and broadly exposed; disk with feebly impressed series of rather

coarse impressed punctures, the intervals nearly flat in both sexes and

minutely, sparsely punctate, the punctures arranged in single series and more

distinct in the male. Legs and abdomen in both sexes nearly as in gracilis.

Male.—Eyes rather large, separated by one-fourth more than their own

width ; antenne two-thirds as long as the body, just visibly stouter toward

apex, the ninth joint much more than twice as long as wide and nearly parallel.

Female.—EHyes separated by nearly twice their width ; antenne one-half as .

long as the body, feebly incrassate toward apex, the ninth joint very feebly

obconical and nearly twice as long as wide.

Length 8.0-9.0 mm.; width 2.38-2.8 mm.

Nevada; California (Siskiyou Co.).

This species greatly resembles gracilis, but is more slender and

rather less convex, with the legs entirely black, and the punctures

of the elytral striz much larger and more conspicuous. All the

specimens before me are deep black, but, as the name indicates, the

color may perhaps occasionally be of a bluish tinge.

LOBOPODA Sol.

Allecula Say, Lec.

The species of Lobopoda are, as a rule, above the average of the

family in point of size, and are sometimes surprisingly closely allied

among themselves. The form is generally more or less oblong-oval

and gradually pointed behind, and the punctures of the elytral series

are almost invariably finer or more or less linear toward apex, often

becoming completely obsolete.

The tarsal lobes are especially highly developed, and generally

differ sexually to a marked degree, the lobes of the penultimate joint

being, however, usually free from sexual modification. Attempts

have been made to subdivide the genus upon the basis of variation

in the number and disposition of the lobed joints in the male and

female, but, as in most characters of this nature, there are so many

intergrading forms, that these efforts have only met with partial

success.

These tarsal modifications are useful, however, in tabulating the

species, but as the number of representatives within the limits of

the United States is comparatively small, and as the male of several

of our species is still unknown to me, I have, in the following pre-

liminary table, simply employed general characters relating to

superficial form and sculpture, and based upon the limited material

before me.

Our species as far as known may be distinguished as follows :—

less densely aggregated along the median line and in front of the scutellum.

L. socia Lec.—Proc. Ac. Phil., VII, 1854, p. 84.—Elongate-elliptical,

castaneous above, the under surface and posterior legs blackish ; anterior and

intermediate legs and antenne rufo-castaneous ; integuments rather polished

throughout, the pubescence voarse, rather short, sparse. Head somewhat

finely, sparsely, unevenly punctate; eyes large and approximate; antenne

very slender and filiform, nearly one-half as long as the body, the joints

cylindrical and nearly four times as long as wide, the third slightly shorter

than the fourth. Prothorax not quite twice as wide as long, the apex truncate

and three-fourths as wide as the base, the latter transverse, the sinuations

broad and strong; sides just visibly convergent from the basal angles to ante-

rior third and straight, thence strongly rounded to the apex; basal angles

right, not appreciably blunt; disk rather coarsely, very sparsely and unevenly

punctate, the punctures larger and closer before the scutellum and narrowly

along the median line; basal fovee large and distinct. lytra four times as

long as the prothorax, and, in the middle, about one-fourth wider, gradually

acute toward apex, the base very slightly wider than that of the prothorax ;

The description is drawn from the female. It is very closely

allied to mexicana Champ., but differs from the corresponding sex

of that species in its slightly closer punctuation on the elytral inter-

vals; there are usually but two punctures in a transverse direction

in mexicana, while in socia there are about three, which are rather

smaller than in the former. This is the only decided difference of

any kind which it is possible to discover, but I think that the two

species are distinct and that this would be clearly evident if the

males were compared. The elytra are perfectly simple and nar-

rowly rounded at apex in the female of socia. This species is not

at all closely related to punctulata.

L. subcuneata n. sp.—Elongate, moderately convex, the elytra cuneate,

black throughout, the head and prothorax smooth but dull and strongly alu-

taceous, the elytra more shining; pubescence coarse, moderate in length,

very sparse. Head finely, rather densely, unevenly punctured, the epistoma

coarsely, much more sparsely so and more shining; eyes very large; antenneze

filiform, fully one-half as long as the body. /Prothorax three-fifths wider than

long, the apex truncate and two-thirds as wide as the base, the latter trans-

verse, with broad and deep sinuations, the angles right, not blunt; sides

parallel and straight in basal two-thirds, then broadly, evenly rounded to

the apex; disk extremely obsoletely impressed along the middle, coarsely,

extremely unevenly punctate, the punctures mingled with smaller ones, dense

toward the median line and base, sparse laterally, with two large impunctate

- discal areas; punctures shallow and variolate, the larger ones elongate-ellip-

tical in form; basal fovee large and distinct but shallow. lytra four times

as long as the prothorax, and, just behind the humeri, very slightly wider ;

sides feebly convergent and nearly straight from this point nearly to the apex,

which is then more abruptly, acutely rounded; disk finely but distinctly

finely, extremely sparsely punctate. Abdomen in the male finely, not strongly,

Texas.

The unique specimen, which is fortunately a male, represents a

remarkably distinct species, not at all closely related to any other

here described, and readily known by its cuneate elytra, dull lustre

and peculiar pronotal punctuation.

The anterior tibie of the male are broadly, very obtusely fontnen

internally at basal two-fifths, this character being common to the

males of a large number of species; in punctulata and oculatifrons

it is more nearly in the form of a broad swelling.

L. punctulata Melsh.—Proc. Ac. Phil., III, 1846, p. 59.—Elongate-

oval, dark castaneous; under surface and legs piceous-black, the tarsi and

antenne rufo-ferruginous ; surface strongly polished throughout, the pubes-

cence rather fine, somewhat long and sparse. Head rather strongly, sparsely

punctate; eyes very large; antenne slender, filiform. Prothoraz one-half to

three-fourths wider than long, the sides distinctly convergent and nearly

straight from the basal angles nearly to the apex, then strongly rounded for

a short distance to the apex, which is truncate and three-fourths as wide as

the base, the latter transverse, the sinuations broad and deep; basal angles

right, not blunt; disk obsoletely, broadly impressed along the middle, very

coarsely, nearly evenly and rather closely punctate, the punctures separated

by two to three times their width ; basal fovez distinct. lytra four times as

long as the prothorax and scarcely perceptibly wider than the base of the

latter, gradually acute behind from the middle; sides nearly straight thence

to the base; disk rather finely but deeply striate, the punctures moderately

coarse and not very approximate; intervals feebly convex, rather finely and

not very closely punctured. Abdomen somewhat strongly, sparsely punctate, °

a little more closely so along the middle in the male. Jegs long, slender, the

basal joint of the hind tarsi equal in length to the remainder.

Male.—Narrower than the female; eyes broadly rounded throughout inter-

nally and subcontiguous through an interval equal to one-half the length of

the epistoma ; antennez fully one-half as long as the body, with the third joint

two-thirds as long as the fourth; anterior tarsi with the four basal joints

strongly lobed beneath, the intermediate with the fourth only, the posterior

with the penultimate narrowly and rudimentarily lobed.

Female.—Kyes separated by fully one-half their own width; antenne two-

Texas; Kansas; New Jersey.

The elytral intervals are slightly more sparsely punctured in the

male than in the female. Punctulata may be distinguished at once

from socia by the pronotal punctuation, the punctures being widely

dispersed except toward base and narrowly along the middle in the

latter, and the size of socia is much greater. In punctulata the

eyes are not absolutely contiguous in the male, but are separated

by a narrow setose isthmus; in oculatifrons they are contiguous

along a fine straight double line which is however also setigerous.

L. oculatifrons n. sp.— Elongate-oval, moderately convex, black

throughout; anterior tarsi ferruginous; antenne piceous, gradually paler

toward apex; lustre polished throughout, the pubescence rather long, fine,

moderately sparse, piceo-fulvous in color and not at all conspicuous. Head

rather coarsely, sparsely punctate; eyes very large but extremely unequal in

the sexes ; antenne long, slender and filiform, one-half as long as the body.

Prothorax from one-half to two-thirds wider than long, subquadrate, the sides

almost parallel and straight in basal two-thirds, then strongly, evenly rounded

to the apex, the latter truncate, three fourths as wide as the base, which is

transverse, the sinuations broad and very strong; basal angles right, not

blunt; disk coarsely, evenly and somewhat closely punctate throughout,

obsoletely impressed along the middle; punctures generally separated by two

to three times their width; basal fovee distinct. lytra four times as long as

the prothorax and about one-fifth wider, gradually acute behind from about

the middle, the sides parallel and nearly straight toward base; humeri very

narrowly exposed ; disk rather finely but strongly, evenly striate, the strial

punctures moderately coarse, deep, perforate and rather approximate; inter-

vals nearly flat, finely punctate, sparsely so in the male, decidedly densely so

‘in the female. Abdomen rather finely but strongly, sparsely punctate, not

noticeably more densely so along the middle in the male. Legs long and slen-

der; basal joint of the posterior tarsi fully equal in length to the remainder.

Male.—More slender than the female, the eyes extremely large, contiguous

along a fine straight line which is nearly as long as the entire epistoma ;

antennez with the third joint two-thirds as long as the fourth; tarsal char-

acters as in punctulata.

Texas.

This species, while allied to punctulata, may be easily distin-

guished by its larger size, more parallel and subquadrate prothorax,

intense black color, the larger eyes of the male and the decidedly

denser elytral punctuation especially of the female. The difference

in the density of elytral punctuation of the male and female is

extremely pronounced.

slightly shorter than the fourth in both sexes. Prothorax one-half wider than

third, then strongly rounded to the apex, the latter truncate and fully two-

thirds as wide as the base, the sinuations strong; disk extremely obsoletely

The male above noted has the legs piceous-black, and the same

condition exists in one of the females. Two other females have the

legs normally red throughout, the species is apparently variable

therefore in this respect. It may be distinguished from punctulata

by its smaller size and much sparser, feebler pronotal punctures, as

well as the more approximate eyes of the female, although in the

male they do not appear to be quite as approximate as in the cor-

responding sex of punctulata. As remarked by Mr. Champion,

erythrocnemis is allied to the Mexican lzxvicollis, but the latter

differs in its longer, more slender form and still sparser, more un-

evenly dispersed pronotal punctuation.

Hirythrocnemis probably inhabits the Mississippi valley as far to

the northward as southern Illinois.

The present species is chiefly notable for its extreme northern

habitat. ‘The eyes are much smaller than in any of the others here

enumerated, and it is also remarkable in having the punctures of

the elytral strie unusually coarse and conspicuous toward base;

but, as is often the case, they become completely obsolete toward

apex.

HYMENORUS Muls.

The two genera Lobopoda and Hymenorus are peculiarly A meri-

can, and together comprise probably more than one-half of the

entire family in our continent, the former being essentially tropical

but entering the southern parts of the United States in moderate

number, and the latter northern in its distribution but overrun-

ning Mexico with many species. Hymenorus is a nearctic, and, to

some extent also, a palearctic genus, while Lobopoda is entirely

neotropical. Hymenorus is one of the best defined of our genera,

although the species are comparatively diversified in facies. The

Species are as a rule much smaller than those of Lobopoda.

The lobes of the tarsi in Hymenorus generally differ from those

of Lobopoda in being small, and never more than two in number

on the two anterior and one on the posterior pair. The last joint

of the maxillary palpi is usually in the form of a right angled tri-

angle, with the apex and the outer side subequal in length, but rarely

it becomes more dilated and quite similar to the prevailing type in

Lobopoda and Allecula. The anterior coxe are always separated

by a narrow but distinct prosternal process, and the posterior by a

narrow acutely angulate abdominal projection, the entire structure

84 Coleopterological Notices, ITI.

of the under surface being surprisingly constant throughout the

genus when compared, for example, with that of Mycetophila.

The posterior tarsi are always slender, with the basal joint elon-

gate and sometimes slightly less, but often much greater, in length

than the remainder. The punctuation and pubescence are, as a

rule, rather dense, the latter pale, somewhat short, coarse and con-

spicuous. The eyes are generally moderate and subequal in size in

the two sexes, but sometimes larger, approaching the form seen in

Lobopoda; they are then nearly always subject to the sexual modi- —

fications characterizing that genus. The antenne are usually slen-

der and filiform, moderate in length, with the joints more or less

obconical, sometimes stouter and distinctly attenuate toward apex,

the third joint being nearly always equal to or slightly longer than

the fourth and similar in the sexes, but in a moderate number of

species becoming very short in the male, although still normal in

the female.

The general form of the body is oblong or oval, rather compact,

with the prothorax subequal in width to the base of the elytra, the

humeri never being in the least broadly exposed at base. The

elytra are almost invariably distinctly punctate-striate, although in

many cases the strial punctures become obsolete toward apex as in

Lobopoda, and in one instance—inquilinus—the strize are com-

pletely effaced throughout, being traceable with great difficulty only

in the immediate neighborhood of the base.

While the species are usually constant and easily separable among

themselves by marked structural differences, sexual or otherwise, I

have found the tabular classification of them a most difficult and

unsatisfactory problem. None of the structural peculiarities so

valuable in separating allied forms, continue constant throughout

a sufficient number of species to enable us to define large groups

with rigorous exactness, and I have been forced finally to adopt a

method of subdivision depending largely upon general habitus and

sculpture.

There are probably but few species common to the United States

and Mexico, at least below the latitude of Durango. Mr. Cham-

pion has kindly sent me representatives of his emmenastoides, palli-

dus, colonoides, guatemalensis and americanus, all of which are

widely different from any species which we possess. The densely

punctate species, so characteristic of the southwestern fauna, are for

the most part more or less local in distribution, contrasting strongly

Coleopterological Notices, ITT. 85

in this respect with the more northern and eastern polished and

sparsely punctate forms.

It is hoped that the following table may aid somewhat in identi-

fication, but as there are undoubtedly many species yet to be dis-

covered, it will probably prove more or less ambiguous unless used

solely as a key to the descriptions :—

Kentucky. Cab. LeConte.

The unique representative is a male, and is not in very good

condition for observation. In this specimen the intromittent organ

is far extruded, and the curious hinged spike protrudes from the

groove along its lower surface in a nearly perpendicular direction.

The fourth joint of the maxillary palpi is rather short and robust,

the apex scarcely as long as the outer side.

This remarkable species is quite similar in general appearance to

certain members of the genus Mycetophila, especially MZ. megalops,

and the slender tarsi, with unusually small narrow and inconspicu-

ous lobes, add to this superficial resemblance an element which

may indicate a still closer affinity. It is readily distinguishable,

however, from any of those species of Mycetophila which it most

nearly resembles, by its punctate-striate elytra and altogether differ-

ent form of the prothorax, the latter being strongly rounded at apex.

the eyes moderate, separated by a little more than their width; antenne

rather short, moderately slender, filiform, two-fifths as long as the body, the

by three or four times their own diameters. lytra nearly three and one-half

times as long as the prothorax and not appreciably wider, rather gradually,

acutely rounded behind; sides parallel and nearly straight; disk with almost

completely unimpressed series of small but deep punctures, the series entirely

obsolete toward apex, more distinct toward base, the intervals finely but

deeply, sparsely punctate. Abdomen finely, sparsely punctate, the meta-

sternum rather coarsely, sparsely so externally. Legs slender, the basal joint

of the hind tarsi fully one-third longer than the remainder. Length 5.3-6.0

The individual above described is a male from Pennsylvania, and

represents the typical form. The numerous specimens before me

are divisible into six sections, which are in all probability distinct

species, but time and material are wanting to definitely fix their values

at present. One of these, represented by twelve specimens, is rather

more slender than the type, with bright flavate legs and piceous

upper surface, the elytra being feebly and suffusedly rufescent toward

base. Another, represented by a single specimen from Florida, has

the pronotum rather coarsely punctate, and the eyes larger. Still

another, represented by a single male from Indiana, is larger, with

the pronotum very finely punctate, the eyes being large and sepa-

rated by less than their own width.

At a future time, with more material, it will be my endeavor to

properly define these allied forms.

3.H. infuscatus n. sp.—Oblong-oval, moderately convex, polished

throughout, dark brownish-piceous, the under surface and legs slightly paler,

rufescent ; pubescence rather long and coarse, somewhat sparse but conspicu-

of the usual fovee, rather coarsely and sparsely punctate. lytra four times

as long as the prothorax, and, behind the middle, just visibly wider than the

latter, acutely ogival in apical third; sides very feebly arcuate, especially

behind, thence nearly straight to the base and continuous with those of the

prothorax ; disk with feebly impressed rows of rather small but distinct,

rounded punctures which become obsolete toward apex, the intervals feebly

convex, finely, confusedly and rather sparsely punctate. Abdomen minutely,

sparsely punctate throughout. Zegs slender, the basal joint of the hind tarsi

equal in length to the remainder. Length 5.7 mm.; width 2.2 mm.

The single specimen before me is a male. The species does not

greatly resemble any other, although perhaps most closely allied to

niger. 'The pubescence is unusually long, and the prothorax short

and coarsely punctate.

Michigan.

The species above described is not likely to be confounded with

any other, being distinguishable by its long antenne with strongly

obconical joints, the third a little longer than the fourth—which is

unusual in this section,—its larger eyes and incomplete elytral

series. It also differs in its very fine, extremely sparse pronotal

punctuation. The two specimens before me are apparently females.

5 H. punctulatus Lec.—Proc. Ac. Phil., 1859, p. 78.—Oblong-oval,

moderately convex, polished and pale rufo-testaceous throughout, the pubes-

cence fine, short, subrecumbent, pale but rather sparse and not conspicuous.

Head rather large and strongly convex, somewhat coarsely, sparsely punctate,

the eyes small, separated by two-fifths more than their own width; antenne

rather short and robust, distinctly attenuate toward apex, but little more

than one-third as long as the body, the intermediate joints somewhat feebly

obconical, the third and fourth subequal. Prothorax strongly transverse,

about twice as wide as long, the apex broad and subtruncate, the base trans-

verse, broadly, feebly arcuate in the middle; sides broadly arcuate and con-

vergent in apical two-fifths, thence nearly parallel to the basal angles which

are obtuse and rather blunt; disk scarcely at all impressed, finely, rather

densely punctate, the punctures separated by about twice their own diameters.

Elytra nearly five times as long as the prothorax and rather distinctly wider,

somewhat abruptly ogival in apical third; sides parallel and just visibly

arcuate ; humeri rounded and oblique externally, but not exposed at base;

disk with feebly impressed series of fine, rather approximate punctures, the

intervals minutely, confusedly and somewhat sparsely punctate. Abdomen

minutely, rather feebly and sparsely punctate. Length 6.3 mm.; width 2.6 mm.

California. Cab. LeConte.

Although bearing a general resemblance to the obscurus group

of eastern species, punctulatus differs remarkably from all of them

in its fine and much shorter pubescence. The type specimen is a

male, and is in a poor state of preservation, the pronotum being

broken and crushed so that it is somewhat distorted in outline; the

above measurements have made allowance for this as far as possible.

The posterior legs are entirely wanting in the type. It is distin-

guishable from infuscatus by its broader form, relatively shorter

prothorax and longer elytra, shorter, stouter antenne and short

pubescence.

The antenne are quite robust, unusually compact and cylindrical,

with the third joint just visibly longer than the fourth and both

of these much longer than joints five to eleven, which are equal in

length, the fifth about one-half longer than wide, the tenth nearly

two and one-half times as long as wide.

6 H. melsheimeri n. sp.—Oblong-elongate, parallel, moderately con-

vex, piceous-black above, the entire under surface, legs and antenne paler,

rufo-ferruginous ; surface polished ; pubescence nearly as in obscurus. Head

rather coarsely, deeply, sparsely punctate, the eyes moderate, separated by

slightly more than their own width; antenne short, stout, filiform, not more

than one-third as long as the body, the last three joints rapidly shorter, joints

three to nine equal in length, the intermediate almost parallel, twice as long

as wide. Prothorax three-fourths wider than long, the apex broadly arcuate,

continuous in curvature around the apical angles, the sides becoming parallel

and feebly arcuate almost through basal two-thirds; basal angles right, not

rounded ; base transverse, with a short rounded median lobe; disk obsoletely

impressed only along the middle toward base, finely, sparsely punctate, the

punctures round, perforate and separated by about three times their own

diameters. /lytra nearly four times as long as the prothorax and equal to it

in width, rather gradually, acutely pointed in apical third; sides parallel and

nearly straight ; disk with feebly impressed series of fine, not very close-set and

inconspicuous punctures, the intervals minutely, sparsely punctate. Abdomen

finely, sparsely punctate. Zegs slender; basal joint of the hind tarsi nearly

one-half longer than the remainder, slightly arcuate. Length 7.3 mm.; width

2.7 mm.

Michigan.

The unique specimen before me is immediately distinguishable

from any other in this section by its narrower, more parallel form,

and unusually short, rather stout, but filiform antenne, with nearly

parallel-sided joints. The sex of the type cannot be definitely deter-

mined without dissection.

7 H. obesus n.sp.—Broadly oblong-oval, rather strongly convex, polished

throughout, piceous-black, the abdomen black ; legs piceous, the tarsi paler ;

antenne rufo-fuscous ; pubescence moderate in length, rather sparse, coarse,

pale in color. Head sparsely, somewhat coarsely punctate; eyes moderate,

separated by a little less (male), or a little more (female), than their own

width; antenne slender, filiform, two-fifths as long as the body, the joints

nearly parallel, gradually slightly shorter toward apex, the third a little

shorter than the fourth in the male, slender, the fourth three times as long as

wide. Prothorax two-thirds to three-fourths wider than long, the apex two-

thirds as wide as the base, broadly arcuate, the sides parallel and feebly

arcuate in basal half, thence rather strongly convergent and arcuate to the

apex; basal angles distinctly obtuse and blunt; base transverse, the sinua-

tions rather broad and feeble; disk scarcely at all impressed, moderately

coarsely, strongly, sparsely punctate. Flytra from three and one-half to nearly

four times as long as the prothorax, toward base barely perceptibly wider

than the prothorax, a little more distinctly so posteriorly, rather broadly,

obtusely ogival at apex; sides feebly arcuate; disk with feebly impressed

series of small, deep, close-set punctures, the intervals finely, rather sparsely

punctate in the female, very sparsely so in the male. Abdomen finely, sparsely

punctate throughout. Legs slender; basal joint of the hind tarsi much longer

than the remainder. Length 6.7-8.0 mm.; width 3.2-3.5 mm.

New York.

The broadly oval form and more slender, filiform antenne of this

species will serve to distinguish it from pilosus, to which it is rather

closely allied. The third antennal joint of the male is slightly

shorter, and the outer joints decrease more conspicuously in length,

than in pilosus, and the eyes in the same sex are distinctly larger.

8 H. pilosus Melsh.—Proc. Ac. Phil., III, 1846, p. 58.—Rather broad,

oblong-oval, moderately convex, black or piceous black throughout, the abdo-

conspicuous. Head coarsely, deeply, somewhat sparsely punctate, the eyes

moderate, separated by from one-third to one-fourth more than their own

width; antennz slender, filiform, two-fifths as long as the body, the joints

quite distinctly obconical, more than twice as long as wide, the third and

fourth long, exactly equal in both sexes. Prothorax three-fourths wider than

long, the apex broadly arcuate, three-fourths as wide as the base, not evenly

continuous with the sides, the latter convergent and almost evenly arcuate

from base to apex in both sexes; basal angles right and distinctly blunt;

base transverse, the sinuations rather broad and feeble; disk scarcely at all

impressed, quite coarsely, deeply, strongly punctate, the punctures separated

by two to three times their diameters in the male, rather closer in the female.

sparsely so externally. Legs slender, the basal joint of the hind tarsi one-

third longer than the remainder. Length 7.0-8.0 mm.; width 2.9-3.2 mm.

Massachusetts; Michigan; Virginia.

This species is more northern in distribution than obscurus, and

is easily distinguishable by its shorter prothorax, coarser punctua-

tion, rather broader, more depressed form, black color and long

third antennal joint of the male. The series before me is quite

homogeneous.

Two specimens from Florida are not included in the measure-

ments given above, as they appear to represent a much smaller,

though very closely allied species. It will require larger series to

definitely solve this question.

9 Hi. diffficilis n.sp.—Elongate, sub-oval, rather strongly convex, pice-

ous-black throughout, the tarsi paler ; surface highly polished, the pubescence

rather long, coarse, pale, moderately dense. Head coarsely punctate, the

punctures very sparse between the eyes, but dense along the base; eyes

moderate, separated by their own width; antenne about one-half as long as

the body, robust, strongly compressed, feebly attenuate, joints four to eleven

equal in length, very strongly obconical, nearly twice as long as wide, the

third joint short, about two-thirds as long as the fourth in the male. Prothorax

long, about one-half wider than long, broadly, rather strongly arcuate at apex,

the sides parallel or very feebly convergent and nearly straight in basal two-

thirds, then rounded into the apex; basal angles right, not at all rounded ;

sub-basal impression, very coarsely, deeply punctate, the punctures round,

separated by nearly twice their own widths. Elytra about three and one-half

times as long as the prothorax, and, in the middle, slightly wider, rather

obtusely ogival at apex; sides parallel and just visibly arcuate; disk with

unusually broadly, deeply impressed series of punctures, which are coarse,

deep and very conspicuous toward base, but finer, though still distinct, toward

apex; intervals rather strongly convex toward the suture, finely, sparsely

punctate. Abdomen finely, very sparsely punctate throughout. Legs slender ;

basal joint of the hind tarsi distinctly longer than the remainder, though

rather shorter than usual in this section. Length 7.38 mm.; width 3.0 mm.

joint of the male. From obscurus it may be known by its coarser

pronotal punctuation, and more robust and compressed antenne

with more strongly obconical joints and with longer third joint in

the male, and finally from perforatus, by its longer, rather less

coarsely and more evenly punctate pronotum, much shorter antenne

and relatively narrower elytra.

10 H. perforatus n. sp.—Oblong, moderately convex, polished through-

out, dark piceous-brown, the legs and antenne slightly paler and more ferru-

ginous; pubescence rather long, coarse, semi-erect, pale, moderately dense

The three specimens before me are males; in this sex the third

antennal joint is fully two-thirds as long as the fourth.

Although belonging to the same division of the genus as obscu-

rus, the present species differs greatly in its extremely coarse pro-

notal punctuation, and in having the elytra abruptly and distinctly

wider than the prothorax.

Towa.

A somewhat small, broadly depressed species for the present

section of the genus, with rather short prothorax, the sides of

which are unusually convergent from the base. It is easily recog-

nizable by its longer, more shaggy pubescence, as well as by the

antennal structure of the male.

The anterior tarsi of the male have the third joint very rudimen-

tarily lobed, the fourth distinctly so; the intermediate and posterior

tarsi having simply the penultimate joint lobed beneath.

Texas; New York.

The typical form above described is from Texas, the Long Island

specimen being quite similar, except that the pronotum is rather

more finely punctured and the elytral series not so strongly im-

pressed, tending to disappear laterally toward apex. It is singular

that in these species the elytral punctuation of the male is quite

distinctly sparser than that of the female, but the antennz seem to

be about equal in length in the two sexes. Still more striking

sexual differences in punctuation will be alluded to under discretus.'

This species is easily separated from the others of this section by

the characters given in the table.

The description is drawn from the male as I have not positively

identified the female. In this male type the last joint of the maxil-

lary palpi is rather large and elongate, but almost perfectly recti-

triangular, with the outer side subequal to the apex, and the elytral

Series are distinct to the apex.

This is the smallest species of the present group except humeralis,

and does not appear to be at all common.

This is quite a distinct species, readily distinguishable by its

extremely densely crowded punctuation of the pronotum and cor-

male.

size, but easily distinguishable by its dull lustre, finer and much

denser punctuation and strikingly more elongate basal joint of the

separated by scarcely two-fifths their own width ; antenne stout, just percep-

tibly attenuate, not quite two-fifths as long as the body, joints strongly obconi-

cal, the intermediate nearly twice as long as wide, the third just visibly longer

than thefourth. Prothorax scarcely one-half wider than long, the apex broadly,

strongly arcuate, not quite continuous in curvature with the sides, the latter

broadly, strongly arcuate and convergent anteriorly, becoming gradually feebly

arcuate and nearly parallel near the basal angles, which are right and very

slightly blunt; base transverse, the sinuations small and rather strong, the

median lobe subtruncate; disk scarcely at all impressed, rather finely, deeply,

excessively densely punctate and dull, the punctures polygonally crowded

throughout. lytra a little more than three times as long as the prothorax

and about one-fifth wider, rather gradually ogival in apical third; sides thence

parallel and almost straight to the humeri, which are oblique externally but

not exposed at base; disk with very feebly impressed series of small but rather

deep punctures, the intervals finely but strongly, extremely densely punctate.

Abdomen finely punctate, rather sparsely so except along the middle where the

_punctures become extremely dense. Jegs long and slender, the basal joint of

the hind tarsi distinctly longer than the remainder. Length 8.0 mm. ; width

its large size, unusually short, dense pubescence and excessively

dense punctuation, not only of the pronotum, but also the elytra ;

on the latter the serial punctures are not distinct, being goserue

by the crowded punctuation of the intervals.

The fourth joint of the maxillary palpi is normal, moderate in

size, recti-triangular, the apex being subequal in length to the outer

side.

This can hardly be the female of grandicollis, as the dense punc-

tuation along the middle of the abdomen is always a male char-

acteristic when it occurs in the allied Tenebrionide.

17 H. exiguus n. sp.—Oblong-oval, subparallel, rather convex, dark

brownish-castaneous ; under surface, legs and antenne paler, more rufous ;

integuments above rather dull, the pubescence short, very dense, conspicuous.

Head small, less than one-half as wide as the prothorax ; clypeus and inter-

ocular surface finely but not densely punctate, polished; eyes large, separated

by rather less than one-half their width; antenne somewhat slender, about

two-fifths as long as the body, joints five to ten moderately obconical, fully

one-half longer than wide, three and four subequal, nearly cylindrical.

Prothorax nearly three-fourths wider than long, the apex rather broadly but

strongly arcuate, and almost perfectly continuous with the sides, the latter

very broadly rounded anteriorly, becoming parallel and nearly straight only in

basal third; basal angles scarcely more than right, not noticeably rounded ;

base transverse, the sinuations narrow but rather strong; disk evenly convex,

not impressed, rather finely, extremely densely punctate, the punctures rather

shallow, arcuate anteriorly, rapidly shallow and evanescent at their posterior

extremities, in mutual contact in a transverse direction, which gives to the

punctuation a vague appearance of transverse rugulation under low power.

Elytra a little more than three times as long as the prothorax, and, throughout

basal two-thirds, equal in width to the latter, gradually ogival at apex; sides

parallel and barely perceptibly arcuate; disk finely, very densely punctate,

with fine, extremely feebly impressed strie which are just perceptibly punc-

tate. Under surface shining, the abdomen finely, sparsely punctate. Legs

moderate, the basal joint of the hind tarsi equal in length to the remainder.

Length 4.0 mm.; width 1.7 mm.

Texas (El Paso). Mr. Dunn.

A small and inconspicuous species, which is however not closely

related to any other here described. It may be known at once by

its exceptionally small size and large eyes.

In the unique type the prosternum has been broken away at the

sides, exposing the intercoxal process. This, viewed vertically upon

its exposed surface, is well known to be longitudinally convex,

strongly inflexed behind, arriving at the level of the prosternal side-

pieces at the hind margin. The exposure caused by the removal

of the coxa, shows that this process is really a thin hoop, and, that

below its surface, the cavities are almost confluent, being separated

only by what appears to be a thin hyaline membrane; the inner

edge of the hoop is ciliate.

18 H. helvinus n. sp.—Oblong-oval, subparallel, rather convex at the

sides, flatter above, pale rufo-testaceous throughout, the head and prothorax

very slightly darker and more brownish; lustre moderately shining ; pubes-

cence short, rather sparse, pale but inconspicuous. Head finely, rather densely

punctate anteriorly, more sparsely so toward base, the eyes in the male very

large and separated by one-fourth of their own width; antenne long and

rather stout, distinctly longer than one-half the body, joints strongly obconi-

eal, a little more serrate internally than externally, and fully twice as long as

wide, third and fourth subequal in length. Prothorax large, two-fifths wider

than long, the apex strongly arcuate and continuous in curvature with the

sides, the latter broadly, strongly, nearly evenly arcuate throughout, the basal

angles slightly obtuse but not rounded; base transverse, strongly sinuate at

each side of the middle; disk perfectly even, without impressions, convex,

distinctly wider behind the middle than at base, finely, densely punctate, the

punctures all distinctly separated. lytra three times as long as the protho-

rax, and, at the middle, equal in width to the disk of the latter; apex gradu-

ally, acutely ogival; sides parallel and very feebly arcuate, the two bases

exactly equal; disk with very fine strie which are generally very feebly

impressed, but more distinctly so toward the suture, the punctures of the

series fine, approximate and sublinear; intervals nearly flat, finely, rather

densely and confusedly punctured. Abdomen somewhat coarsely but sparsely

punctate, the prosternum densely so. Jegs moderate in length, the femora

robust, the posterior distinctly wider toward apex; tarsi slender, the basal

joint of the posterior slightly longer than the remainder. Length 5.8-6.3 mm. ;

width 2.5 mm.

Texas. National Museum.

The specimens before me are males, and in this sex the last ven-

tral segment is unimpressed, much longer than the fourth and

strongly evenly rounded at apex.

This is a comparatively isolated species, readily known by the

peculiar form of the prothorax, long antenne, very large eyes and

robust femora, as well as by its peculiar pale ochreous coloration.

The prothorax is more than ordinarily deflexed, the longitudinal con-

vexity of the body being therefore apparently greater than usual.

19 H. porosicornis n. sp.—Oblong-oval, subparallel, rather strongly

convex, piceous-black above and beneath, the legs and antenne slightly

paler, rufescent ; surface rather strongly shining, the pronotum finely, feebly

alutaceous ; pubescence coarse, short, pale ochreous but sparse and not very

conspicuous. Head rather large, polished, the epistoma flat, the vertex strongly,

abruptly, longitudinally convex and finely, sparsely punctate; eyes large,

separated by one-fifth their width in the male and two-fifths in the female;

antenne rather long and slender, two-fifths as long as the body in both sexes,

feebly but distinctly attenuate, joints six to ten strongly obconical, the former

a little less, the latter a little more than twice as long as wide, third distinctly

longer than the fourth. Prothorax two-thirds wider than long, the apex

broadly, strongly arcuate and continuous in curvature with the sides, the

latter broadly, strongly arcuate anteriorly, parallel or very feebly convergent

and feebly arcuate from the middle to the basal angles, which are slightly

obtuse and very narrowly rounded ; base transverse, the sinuation at each

side of the middle narrow but strong; disk convex, not distinctly impressed,

finely, rather densely punctate, the punctures round and separated by about

their own diameters. lytra fully three times as long as the prothorax and

equal to the disk of the latter in width, gradually ogival at apex from slightly

behind the middle; sides parallel and nearly straight in basal three-fifths ;

disk with very fine, feebly impressed series of fine but rather deep, close-set

punctures, the intervals finely, confusedly and sparsely punctate. Adldomen

finely, sparsely punctate. Legs moderate in length, rather robust, the basal

joint of the hind tarsi subequal in length to the remainder. Length 6.4—7.5

mm.; width 2.3-2.8 mm.

Texas (Hl Paso). Mr. Dunn.

A distinct species, somewhat resembling rotundicollis, but much

larger, more sparsely punctate and with larger, more approximate

eyes which differ sexually.

The remarkable porous system of the antenne is extremely devel-

oped in the present species. The pores are large and uniformly,

rather sparsely distributed over the entire surface of the joints four

to eleven; they are circular, rather deep, quite independent of the

hairs or bristles, and are filled with a peculiar white stellated mate-

rial, of a spongy-pubescent nature, somewhat similar to the sensi-

tive structure filling the pronotal fovez in many pselaphides.

This species approaches the genus Meneceus, but the thoracic

angles are not in the least prolonged posteriorly.

20 Hi. intermedius n. sp.—Oblong-oval, moderately convex, blackish-

castaneous, the under surface and antenne rufo-fuscous; legs paler and more

flavate; lustre rather shining, feebly alutaceous; pubescence moderate in

length, pale, somewhat dense, very easily removable. Head very small,

rather coarsely and densely punctate, the eyes large, separated by about one-

half their width ; antennz fully two-fifths as long as the body, rather robust,

feebly attenuate, the intermediate joints strongly obconical and scarcely more

than one-half longer than wide, the third slightly longer than the fourth.

Coleopterological Notices, ITT. 103

Prothorax nearly three-fifths wider than long, the apex strongly arcuate and

continuous with the sides, the latter becoming parallel and distinctly arcuate

toward base, the basal angles right, not distinctly blunt; base transverse, the

sinuations moderate; disk very obsoletely impressed in the middle toward

base, finely, deeply punctate, the punctures separated by scarcely their own

widths, the interspaces rather strongly alutaceous. lytra fully three times

as long as the prothorax and equal in width to the latter, rather abruptly

ogival in apical third; disk with feebly impressed series of small but distinct,

not very approximate punctures, the intervals minutely and moderately closely

punctured. Abdomen minutely, very sparsely punctate. Legs moderate; basal

joint of the hind tarsi almost two-fifths longer than the entire remainder.

Length 5.5 mm.; width 2.2 mm.

Texas. Mr. W. Jiilich.

_ The general form of the body recalls rotundicollis, but the latter

differs in its larger size, much smaller eyes and broader terminal

joint of the palpi. In intermedius this joint is almost normal, recti-

triangular, with the very oblique apex scarcely longer than the

outer side. The head seems to be even unusually small.

There is but little variation of any kind in the three specimens

before me.

21 H. prolixus n. sp.—Elongate, subparallel, moderately convex, aluta-

ceous in lustre and rather dull, piceous to castaneous, the legs, abdomen and

antenne paler and more rufous; pubescence short, rather sparse and incon-

spicuous. Head finely punctate, nearly evenly and rather densely so through-

out; eyes large, separated by one-third their width in the male, one-half in

the female; antennz long and slender, nearly one-half as long as the body,

the joints strongly obconical and much more than twice as long as wide, the

third and fourth equal. /rothorax one-half wider than long, the apex and

sides nearly as in occidentalis; basal angles right and narrowly but very dis-

tinctly rounded ; base transverse, the sinuations broad and strong, the median

lobe broadly arcuate, projecting posteriorly as far as the basal angles; disk

scarcely impressed, finely, deeply, densely punctate, usually slightly more

sparsely so toward base, the punctures anteriorly generally distinctly, some-

times rather widely separated. lytra fully four times as long as the protho-

rax and very slightly wider than the latter, rather gradually, obtusely ogival

at apex; sides parallel and nearly straight, the humeri somewhat abruptly

rounded to the prothorax; disk with very feebly impressed series of fine but

deep, close-set, sublinear punctures, the intervals finely, confusedly and rather

sparsely punctate. Abdomen, under surface and legs nearly as in occidentalis.

Length 8.5-9.7 mm.; width 2.9-3.2 mm.

New Mexico; Arizona.

This species is somewhat related to occidentalis, but differs in

several characters to a decisive degree. The punctuation of the

pronotum in prolixus is much finer and less dense, and the elytral

punctures are decidedly:sparser; the antennz are more slender,

with the joints more elongate, the comparisons being made from

the male; the base of the prothorax is scarcely at all oblique toward

the angles, and finally, the two sexes are similar in size and form,

while in occidentalis the male is notably more slender than the

female and with a less transverse prothorax.

The maxillary palpi are nearly as in occidentalis, but the fourth

joint is rather narrower. I have seen six specimens.

Mr. Champion writes me that this species is rather closely allied

to durangoensis, but is distinct.

22 HW. occidentalis Champ.—Biol. Cent.-Amer., Coleopt., IV, Pt. i,

p. 425.—Rather elongate, parallel, moderately convex, dull and alutaceous,

castaneous, the legs and under surface rather paler, rufescent; pubescence

short, rather fine, moderately dense, not at all conspicuous. Head finely,

densely punctate anteriorly, more coarsely and slightly more sparsely so

between the eyes, which are large, separated by one-third their width in the

male and one-half in the female; antenne about two-fifths as long as the

body, subfiliform, moderately stout, the joints about twice as long as wide,

third slightly longer than the fourth. Prothorax one third (male). to one-half

(female) wider than long, the apex broadly, rather feebly arcuate, three-

fourths as wide as the base, not continuous in curvature with the sides, the

latter parallel and nearly straight in basal half, thence moderately convergent

and arcuate to the apex ; basal angles right, slightly blunt; base posteriorly

oblique toward the basal angles, broadly, feebly arcuate in middle half; disk

scarcely impressed, rather coarsely, very densely punctate, the punctures

almost in contact but circular and not polygonally crowded. Llytra three and

one-half times as long as the prothorax and very slightly wider, gradually,

obtusely ogival toward apex; sides thence parallel and nearly straight to the

humeri, which are obliquely, broadly rounded externally to the prothorax ;

disk with rather broadly, feebly impressed series of small, close-set punctures,

the intervals finely, confusedly and moderately closely punctured. Abdomen

polished, finely, sparsely punctured, a little more closely so along the middle

in the male. Legs decidedly robust, the basal joint of the hind tarsi much

longer than the remainder. Length 10.0-11.0 mm.; width 3.3-3.8 mm.

Wexas:

The fourth joint of the Sap SUES palpi is strongly dilated, with

the apex much longer than either side, and, in outline, is nearly as

in Lobopoda.

The large size and elongate-parallel form will readily serve to

differentiate this species from any other within our faunal limits,

being approached in these neepects only by prolixus.

23 Hi. dorsalis Schz.—Proc. Am. Phil. Soc., XVII, p. 370.—Oblong-oval,

rather strongly depressed, dark rufo-ferruginous, the elytra black in apical

two-thirds ; abdomen, legs and antenne paler; surface moderately shining,

feebly alutaceous ; pubescence short, rather fine and sparse, pale but not con-

spicuous. Heud rather sparsely, coarsely punctate, the eyes large, somewhat

narrowly rounded within, separated in both sexes by one-third to one-fourth

their own width ; antennez long, slender, filiform, fully three-fifths as long as

the body in the male, joints almost parallel, much more than twice as long

as wide, third much shorter than the fourth in the male, subequal in the

female. Prothorax three-fifths wider than long, the apex strongly arcuate and

continuous with the sides, the latter broadly arcuate toward the base, which

is transverse, with the sinnations small and feeble; angles right in the male,

somewhat obtuse in the female, not rounded ; disk widest at about basal third,

coarsely and rather sparsely punctate, feebly deplanate toward the basal angles

in the female, very obsoletely impressed in the middle toward base. Llytra a

little more than three times as long as the prothorax and very slightly wider,

gradually ogival at apex; sides parallel and almost straight in basal three-

fifths, the humeri slightly exposed; disk with feebly impressed series of

exceedingly fine, scarcely distinguishable, not very close-set punctures, the

intervals finely, sparsely punctate, the punctures not distinctly finer than

those of the striz. Abdomen finely but distinctly, rather sparsely punctate.

Legs slender, the basal joint of the hind tarsi fully one-third longer than the

remainder. Length 5.7 mm.; width 2.2-2.3 mm.

Florida (Tampa and Capron). Mr. Schwarz.

A widely isolated species, not only in coloration but in its long

filiform male antenne, large eyes and peculiarly small inconspicuous

serial punctures. The male antenne, with the third joint shorter

than the fourth, differ from those of any other species belonging to

the present group which I have seen. In the female the antenne

are shorter and stouter.

The fifth segment in the male is much shorter and more obtusely

rounded than in the female, and, in both sexes, the lateral subapical

emarginations of this segment are unusually strong. ‘The sexual

difference in the eyes is not marked; in fact in the single female

before me they are, if anything, more narrowly separated than in

the male.

The fourth joint of the maxillary palpi is very broad, the apex a

little longer than either side, and the angle at the base slightly more

than right.

24 Hi. discretus n. sp.—Oblong, subparallel, moderately convex, pice-

and sparse. Head rather strongly, sparsely punctate, the eyes large, separated

by two-fifths their width ; antenne stout, two-fifths as long as the body, feebly

attenuate toward apex, joints four to eleven very slightly increasing in length,

the sixth joint on the compressed side fully one-half longer than wide, obconi-

cal, the tenth twice as long as wide, third and fourth equal in length. /Pro-

thorax three-fourths wider than long, the apex broadly arcuate and continuous

with the sides, the latter broadly, feebly arcuate and convergent: anteriorly,

more strongly arcuate toward the basal angles, which are slightly obtuse but

scarcely noticeably blunt; base transverse, the median lobe small and short,

rounded; disk quite distinctly wider at basal third than at base, scarcely

at all impressed, broadly explanate laterally toward the basal angles and

narrowly, feebly reflexed along the sides in their vicinity, coarsely, strongly

punctate throughout, the punctures circular and generally separated by

nearly their own diameters. lytra equal in width to the prothorax and

about three and one-half times as long, gradually, rather acutely ogival at

apex ; sides parallel and nearly straight in basal two-thirds ; disk with feebly

impressed series of rather small but distinct punctures, the intervals finely,

rather sparsely, confusedly punctured. Abdomen finely but rather strongly,

sparsely punctured, almost totally impunctate toward apex; metasternum

rather coarsely, sparsely punctate externally, rapidly very finely, densely so

toward the middle; prosternum densely punctured. Legs rather long, the

femora robust; basal joint of the hind tarsi two-fifths longer than the remain-

der. Length 6.2-7.4 mm.; width 2.4—3.1 mm.

Massachusetts; New York.

The general form throughout recalls that of fustcornis, and, as

in that species, the antenne are notably robust, at least in the

female, and attenuated, but here the resemblance altogether ceases.

In pronotal punctuation the two species stand almost at the extremes

of the genus in regard to the magnitude of the punctures, and the

basal joint of the hind tarsi is conspicuously longer in discretus.

The description is taken from the female. The male is smaller,

with entirely polished upper surface, the eyes separated by about

one-fourth of their width, and the antenne more slender and much

longer, being a little more than one-half as long as the body. The

pubescence, also, seems to be a little longer, and the elytral punc-

tuation is decidedly sparser; the pronotum is not so decidedly ex-

planate toward the basal angles.

In both sexes the fourth joint of the maxillary palpi is rather

strongly dilated, triangular, with the apex a little longer than the

outer side. The fifth elytral stria is more strongly impressed

toward base. ,

scarcely one-fourth wider, the apex gradually acute; sides arcuate and nearly

continuous with those of the prothorax; disk coarsely, deeply striate, the

strie coarsely, deeply and approximately punctate, the intervals moderately

convex, highly polished, rather finely, sparsely punctured. Under surface

sparsely throughout. Legs rather long, the basal joint of the hind tarsi

slightly longer than the remainder. Length 6.8-7.5 mm.; width 2.8-3.2 mm.

Florida (Key West); Texas. Mr. Jiilich.

A remarkably distinct species, apparently inhabiting the same

regions as densus; in outline somewhat similar to that species but

much larger, more shining, more coarsely, sparsely punctate and

pubescent, and with very much longer antenne. The eyes in the

ample series before me, do not vary measurably in the interval

separating them, which is much less than in densus.

somewhat sparsely punctured ; eyes large and convex, separated in both sexes

by about two-thirds their width ; antenne stout, one-third as long as the body,

joints four to ten very strongly obconical, slightly longer than wide, more

serrate internally than externally, third slender, slightly longer than the

Florida; Texas; Ohio.

The color is frequently piceous-black throughout above, the legs

always remaining pale. The eyes in sixteen of the seventeen speci-

mens before me are perfectly uniform, and separated by two-thirds

of their own width, but in the remaining specimen, which appa-

rently does not differ in any other particular, they are smaller and

separated by their full width; this specimen singularly enough is a_

male, and must be regarded as an accidental aberration.

A few specimens in the cabinet of Mr. Jiilich are labeled Ohio,

and are said to have been collected by Mr. Dury.

Arizona. Mr. Morrison.

A small, densely punctate and unusually dull form, rather closely

allied to densus and perfectly similar to the latter in the peculiar

coloration of the body, but differing in its much finer, still denser

punctuation, smaller eyes, and in its decidedly more depressed form.

28 H. dissensus n. sp.—Oval, moderately robust, rather convex, casta-

neous ; legs and antenne pale, flavo-testaceous ; lustre somewhat alutaceous,

the elytra more strongly shining, pubescence moderate in length and density,

base transverse, the sinuations just perceptible; disk evenly convex, rather

coarsely, very deeply punctate, the punctures round, separated by rather less

than their own widths, the bottom of each highly polished, the interspaces

strongly alutaceous and granulato-reticulate. Elytra scarcely two and one-

half times as long as the prothorax, and, at the middle, but slightly wider ;

apex somewhat gradually acute; sides broadly arcuate, nearly continuous

with those of the prothorax; disk with moderately impressed series of very

coarse, deep, perforate and approximate punctures, the intervals nearly flat,

Texas (Galveston).

A distinct species, easily recognizable by its small size, oval, con-

vex form, coarse punctuation especially of the elytral series, and

rather long prothorax. It does not appear to be especially related to

any of the Mexican species of the Biologia, but belongs near densus.

but deeply punctate, the punctures between the eyes separated by about their

own diameters, the eyes moderate, separated by very nearly their own width

in both sexes; antenne long, slender and filiform, three-fifths as long as the

tures, the intervals polished, nearly flat, finely and sparsely punctate. Abdo-

men finely, very sparsely but rather strongly punctate, the prosternum densely

so, the propleure very sparsely. Legs slender, the basal joint of the hind

tarsi equal in length to the remainder. Length 5.5 mm.; width 2.4—2.6 mm.

Arizona.

The peculiar form of this species—distinetly widest behind,—

together with the long antenne and coarsely perforate elytral striz,

will readily serve to distinguish it. It belongs near densus, and

has the coarse punctuation of the pronotum characterizing that and

some allied species, but the form is here rather less convex; it is

also allied to the Mexican pallidus Champ., but is darker in color,

and has the pronotal punctuation less dense and not rugulose.

Five specimens, which are extremely uniform among themselves

in size and outline; some are entirely pale testaceous from imma-

turity.

30 Hi. testaceus n. sp.—Elliptical, rather strongly convex, pale rufo-

testaceous throughout, strongly shining ; pubescence moderate in length, pale

but sparse and not conspicuous. Head rather coarsely, deeply and sparsely

punctate ; eyes large, separated by one-half their width in the male and two-

thirds in the female; antenne rather slender and filiform, two-fifths as long

as the body, the joints moderately obconical, the intermediate about twice as

long as wide, third and fourth equal. SProthorax nearly three-fourths wider

than long, the apex narrowly, strongly arcuate and continuous with the sides,

which are strongly oblique and feebly arcuate anteriorly, more strongly arcuate

in basal two-fifths, becoming very feebly convergent toward the basal angles,

the latter right and slightly blunt; base transverse, the median lobe small,

short, rounded ; disk scarcely at all impressed, coarsely, deeply, rather sparsely

punctate, the punctures generally separated by nearly their own diameters,

the interspaces highly polished. lytra but slightly more than three times

as long as the prothorax, and, at the middle, very slightly wider, gradually,

rather acutely ogival in apical two-fifths, the sides parallel and feebly arcuate,

the two bases exactly equal; disk with fine but distinctly impressed series of

fine but deep and distinct punctures, which are noticeably linear, the intervals

feebly convex, polished, finely but distinctly, sparsely punctate. Abdomen

minutely, feebly, sparsely punctate. Legs rather slender, the femora moder-

ately robust; basal joint of the hind tarsi slender, at least one-third longer

than the remainder. Length 6.0 mm.; width 2.6—-2.8 mm.

Arizona.

This distinct species is somewhat similar to helvinus in outline,

and in its pale color and rather more than ordinarly deflexed pro-

notum, which gives it a relatively strong longitudinal convexity.

It differs conspicuously from helvinus in its very coarse, sparse

pronotal punctuation; smaller eyes, much less robust femora and

shorter, more slender antenne. It is represented by four specimens.

31 H. rotundicollis n. sp.—Oblong-oval, rather strongly convex,

piceous-black throughout, the legs and antenne but slightly paler, rufescent,

rather strongly shining, the pubescence moderately long and dense, very

easily denuded. Head feebly convex, finely and somewhat densely punctate,

the punctures distinctly separated ; eyes moderate, separated by about their

own width; antenne moderately stout, filiform, scarcely one-half as long as

the body, the joints distinctly obconical, twice as long as wide, the third and

fourth equal. JProthorax large, three-fifths wider than long, the apex very

strongly, rather narrowly arcuate and continuous with the sides, the latter

parallel and nearly straight in a little more than basal third ; base transverse,

the median lobe short, broadly rounded, distinct; basal angles right and

slightly blunt; disk feebly explanate near the sides toward base, more

especially in the female, not distinctly impressed, rather finely but strongly,

somewhat sparsely punctate, the punctures separated by scarcely their own

widths, the interspaces strongly shining. £lytra rather distinctly more than

three times as long as the prothorax, gradually ogival in apical two-fifths ;

sides parallel and straight in basal three-fifths ; disk scarcely equal in width

to the prothorax, with feebly impressed series of small but deep, brevilinear,

not very close-set punctures, the intervals minutely, confusedly and moder-

ately closely punctured. Abdomen finely, very feebly and sparsely punctate.

Legs rather slender. Length 5.6-6.4 mm.; width 2.1-2.6 mm.

Arizona.

In the four specimens before me there is not one entire posterior

tarsus, but the basal joint is slender and appears to be slightly longer

than the remainder.

The fourth joint of the maxillary palpi is strongly dilated, as

much so as in Lobopoda, the angle at the point of support being

distinctly obtuse, and the apex much longer than either side and

rather widely open and spongiose throughout its extent.

The strongly arcuate apex of the prothorax, rather sparse punc-

tuation of the pronotum and palpal structure, will readily serve to

identify this distinct species. The Central American emmenasto-

32 MH. inquilinus n. sp.—Oblong-oval, moderately convex, rufo-testa-

ceous, the elytra still paler and more flavate; upper surface polished, the

pronotum feebly alutaceous; pubescence rather sparse, semi-erect, coarse,

flavate in color. Head decidedly large, strongly, longitudinally convex,

minutely, excessively sparsely punctate, the epistoma abruptly flat and more

closely but still sparsely punctate; eyes small, separated by distinctly more

than their own width; antenne stout, cylindrical, nearly one-half as long as

the body, distinctly attenuate, the joints obconical, third and fourth equal.

Prothorax short, twice as wide as long, the apex subtruncate, just visibly

arcuate, three-fourths as wide as the base, the latter broadly arcuate in the

middle, the lobe extending posteriorly fully as far as the angles; sinuations

extremely feeble; basal angles right; sides broadly arcuate throughout, a

little more convergent anteriorly ; disk slightly wider behind the middle than

at base, feebly explanate near the sides toward base, not distinctly impressed

or foveate, very finely, densely punctate, the punctures distinctly separated.

Elytra fully three times as long as the prothorax, and, throughout, slightly

narrower than the disk of the latter, distinctly dehiscent in apical third, the

two bases exactly equal; sides parallel and nearly straight, the apex some-

what obtusely ogival; disk rather finely, moderately closely punctate, with-

out trace of impressed lines except the sutural, which is very feeble, without

trace of punctured series except extremely indefinitely toward base. Abdo-

men finely, moderately closely punctate, the fifth segment almost completely

impunctate. Legs short and very robust, the tarsi short; basal joint of the

posterior as long as the remainder. Length 4.5 mm.; width 1.8 mm.

California.

The single specimen before me is a male, and differs so greatly

from the usual forms in general appearance, that for a long time I

thought that it would have to be considered the type of a distinct

genus; but, on close examination, no character of any kind can be

discerned by which to distinguish it from Hymenorus.

The maxillary palpi are of the usual form, and the lateral sub-

apical emarginations of the fifth ventral segment are deep and dis-

tinct. The claws are rather short and stout and finely, closely

pectinate nearly throughout the length. ‘This species is said to be

myrmecophilous.

33 HI. fusicormis n. sp.—Oblong, parallel, rather robust and feebly

convex, piceous above, the elytra black; under surface and antenne dark

piceo-castaneous, the legs paler and nore flavate; lustre rather shining, the

two-fifths as long as the body, joints four to eleven gradually increasing in

length, six and seven on the compressed side but very slightly longer than

wide, the tenth three-fourths longer than wide, the third quite distinctly

longer than the fourth. Prothorax three-fourths wider than long, the apex

broadly, moderately arcuate, three-fourths as wide as the base, the latter

broadly, strongly arcuate or feebly lobed in the middle, transverse toward the

basal angles, which are slightly obtuse but not distinctly rounded; sides

broadly, evenly arcuate throughout; disk slightly widest at basal third, very

feebly impressed in the middle near the base, very finely and rather sparsely

punctate. Llytra but little more than three times as long as the prothorax

and equal in width to the disk of the latter, rather abruptly but acutely ogival

in apical third ; sides parallel and straight; disk with very feebly impressed

series of unusually fine and feeble punctures, the intervals still more minutely

and sparsely punctate. Abdomen finely and unusually densely punctate, the

apices of the segments narrowly impunctate, metasternum a little more coarsely

and sparsely so. Legs moderate, normal, the basal joint of the hind tarsi but

slightly longer than the remainder. Length 6.8 mm.; width 2.8 mm.

California (southern).

A remarkably isolated species, to be readily identified by its

smooth, rather shining, minutely, sparsely punctate surface and

robust, compressed and rapidly finely attenuate antenne; the pro-

notum is unusually deplanate along the base to the basal angles,

but strongly declivous thence anteriorly along the sides.

I have seen but a single specimen which is a female. The so-

called sixth segment is about one-fifth as wide as the fifth, truncate

at apex, with the angles rounded.

This species appears to approach the genus Meneceus, but the

posterior angles of.the prothorax do not exhibit the slightest ten-

dency to prolongation backward.

dark piceo-castaneous above, the under surface, legs and antenne pale rufo-

testaceous; elytral suture narrowly rufescent; prothorax rather dull, the

Head rather coarsely punctate, sparsely so between the eyes, the latter moder-

ate in size, separated by nearly three-fourths of their width; antenne long,

somewhat stout, fully one-half as long as the body, the joints gradually nar-

rower and shorter toward apex, the intermediate extremely feebly obconical

and distinctly more than twice as long as wide, the third and fourth equal.

Prothorax a little more than one-half wider than long, the apex rather strongly

arcuate and continuous with the sides, which are broadly arcuate anteriorly,

becoming nearly parallel and straight only very near the base, the basal angles

right, not rounded ; base transverse, the sinuations rather broad, moderately

one-fifth wider, rather obtusely ogival in apical third, the humeri very slightly

rounded to the base of the prothorax; sides parallel and nearly straight in

basal two-thirds ; disk with rather deeply impressed striz of somewhat coarse,

close-set, almost perforate punctures, the intervals somewhat convex, very

minutely, rather sparsely punctured. Abdomen finely, sparsely punctate.

Legs slender, the basal joint of the hind tarsi distinctly longer than the

Arizona.

This species is not at all closely related to any other, the strongly

shining, deeply striate, minutely punctate elytra, coarsely, densely

punctate pronotum, long antennz and oblong, subdepressed form,

at once distinguishing it.

35 Hi. imzequalis n. sp.—Oblong, parallel, strongly convex, the elytra

polished, dark piceo-castaneous, the under surface, legs and antenne paler,

increasing in length, the former two-thirds longer than wide, strongly obconi-

cal, the tenth much more than twice as long as wide, third very distinctly

longer than the fourth. Prothorax short, three-fourths wider than long, the

apex two-thirds as wide as the base, almost transversely truncate, the base

transverse, the median portion broadly, distinctly arcuate; sides broadly

arcuate and strongly convergent anteriorly, very slightly convergent and

nearly straight in basal two-fifths, the angles rather distinctly obtuse -but not

at all rounded; disk not impressed, convex, very coarsely, extremely densely

and not very deeply punctate, the punctures in contact and somewhat poly-

gonally crowded. Jlytra nearly four times as long as the prothorax and just

perceptibly wider, the apex gradually, evenly ogival, the humeri feebly,

obliquely rounded externally to the prothoracic base, the sides parallel and

nearly straight; disk with extremely feebly impressed series of small but

deep, close-set and almost perforate punctures, which are slightly oblong;

intervals highly polished, minutely, sparsely punctate. Abdomen minutely,

sparsely punctate, the anterior portions of the body coarsely so, the prosternum

and propleure extremely densely so. Legs moderate in length, rather densely

pubescent, the femora slightly robust; basal joint of the hind tarsi subequal

but scarcely at all rounded; disk broadly, very feebly impressed in the middle

toward base, rather coarsely, deeply punctate, the punctures distinctly sepa-

rated toward the middle, rather finer and densely crowded toward the sides.

Elytra nearly three times as long as the prothorax, and, throughout, scarcely

perceptibly wider, the sides parallel and straight to apical third, the apex

ogival; disk finely, rather sparsely punctured, with series of very fine incon-

spicuous punctures, the series rather distinctly impressed near the suture but

becoming almost completely unimpressed laterally. Under surface very finely,

sparsely punctured, the prosternum and propleure finely, extremely densely

A small subparallel species, somewhat related to densus, but

differing greatly in form, structure of the antenne, coloration and

Florida.

This species belongs somewhat near tenellus, but differs greatly

‘in coloration, in its broader form, and especially in its wider elytra

and more transverse prothorax; the eyes in the unique female are

decidedly smaller, and the antenne still more slender.

Lower California (Cape San Lucas). Cab. LeConte.

In its oblong form, with the elytra rather short, parallel and

slightly wider than the prothorax, this species is an analogue of

sobrinus and floridanus, but it differs from both of the latter in

its finer, much denser punctuation, more elongate Drees and

slightly shorter, more robust antenne.

California (Coronado Beach, San Diego Co.). Dr. Blaisdell.

This species is allied to confertus, but differs in its larger size,

more elongate form, more slender antenne and longer basal joint

of the hind tarsi. The prothorax, especially, is longer and with the

apex more transverse. I have not positively identified the sexes in

the two individuals before me, but it is probable that the sexual

difference in the eyes is not marked.

A rather inconspicuous, unusually pale species, somewhat dis-

tantly related to deplanatus and distinguishable by its much more

convex form and slightly longer prothorax.

In deplanatus the punctures of the pronotum are small, circular

and distinctly separated, while in the present species they are quite

peculiar, giving under small magnifying power, the rugulose appear-

ance mentioned in the description. The punctures in macer are

much larger than in deplanatus, slightly elongate, closely crowded

arcuate, nearly three-fourths as wide as the base, the latter transverse, the

sinuations narrow but distinct; sides broadly rounded anteriorly, becoming

nearly straight and parallel in basal half, the angles right, not at all rounded ;

disk convex, finely, deeply, very densely punctured, the punctures round and

slightly separated toward the middle. /lytra three times as long as the pro-

Texas (El Paso); New Mexico; Arizona.

The large amount of material before me is rather heterogeneous

and apparently involves two or three very closely allied species.

Some of the smallest forms are females, and two are labeled

“ Florida,” but this is probably an erroneous locality.

The typical form is from E] Paso, and has the punctuation of the

pronotum as described above and the pubescence rather dark in

color. Other specimens have the punctuation of this part slightly

coarser, densely crowded, polygonal and more rugulose, the pubes-

cence being a little longer, pale ochreous and much more conspicuous.

All the specimens agree, however, in the extremely dense punctua-

tion of the elytra, which noticeably exceeds that of deplanatus, and

is even apparently denser than in macer. The species is allied to

than three times as long as the prothorax, and, behind the middle, about one-

third wider, somewhat abruptly and obtusely rounded behind ; sides just visi-

bly arcuate; disk rather distinctly shining, not very finely, deeply, densely

punctate and with distinctly impressed series of slightly coarser, very approxi-

mate punctures. Abdomen very minutely, sparsely punctate, the prosternum

rather densely so but strongly shining. Length 4.8-5.0 mm.; width 1.9 mm.

Arizona. Mr. Morrison.

This is a small species, somewhat allied to punctatissimus, but

easily distinguishable by its sparser punctuation especially of the

elytra, and the more distinctly punctate elytral striz, also by its

still more depressed form.

The two specimens before me appear to be females, as there is no

trace of the peculiar sexual modification of the tibize mentioned by

Mr. Champion.

45 H. gemellus n. sp.—Oblong-elongate, somewhat strongly depressed,

parallel, dark brownish-piceous, the abdomen blackish, remainder of under

surface, legs and antenne paler, rufescent ; integuments somewhat shining,

_ the pubescence short, moderately dense. Head deeply punctured, the punc-

tures rather small and well separated between the eyes, finer and denser

anteriorly ; eyes moderately large, separated by about two-thirds their width ;

antenne moderately long and slightly stout, joints strongly obconical, nearly

one-half longer than wide, third just visibly longer than the fourth. Prothorax

rather more than one-half wider than long, the apex broadly, feebly arcuate,

three-fourths as wide as the base, not continuous in curvature with the sides,

the latter broadly arcuate anteriorly, parallel and nearly straight in basal

half, the angles right; base transverse, the sinuations rather broad and dis-

tinct; disk not impressed, finely, extremely densely punctate throughout, the

punctures round, not quite in contact, the very narrow interspaces shining. *

Elytra quite distinctly more than three times as long as the prothorax and

just visibly wider, somewhat abruptly and obtusely ogival at apex, the humeri

very narrowly exposed ; sides parallel and nearly straight; disk somewhat

finely and feebly striate, the strie finely but distinctly, closely punctate; inter-

vals finely, contusedly and moderately densely punctate, polished. Abdomen

finely, very sparsely punctate. Legs normal, the basal joint of the hind tarsi

equal in length to the remainder. Length 6.0-6.3 mm.; width 2.2-2.3 mm.

Arizona.

A somewhat inconspicuous species, more or less allied to several

others but especially deplanatus. From the latter it is readily

separable by its finer and rather sparser elytral punctuation and

much larger size. The three specimens before me were formerly a

part of the Levette cabinet.

46 Hl. uniseriatus n. sp.—Oblong-oval, rather narrow, convex, highly

polished and pale flavo-testaceous throughout; pubescence somewhat long

and semi-erect, coarse, pale and sparse. Head distinctly, evenly convex,

coarsely, deeply, rather sparsely punctate; eyes small, separated by one-half

more than their own width; antenne moderately stout, a little less than one-

half as long as the body, the joints rather strongly obconical and scarcely

one-half longer than wide, the third scarcely as long as the fourth in the

female. Prothorax about one-half wider than long, the apex three-fourths as

wide as the base, feebly arcuate; sides parallel and almost straight in basal

two-thirds, the apical angles broadly rounded; base transverse, the sinua-

tions broad and rather distinct; basal angles right, distinctly, narrowly

rounded ; disk broadly, feebly impressed in the middle toward base, coarsely,

rather sparsely punctate, the basal fovee small but quite distinct. Hlytra

nearly four times as long as the prothorax and about one-half wider; sides

parallel, broadly arcuate behind, the apex ogival; humeri rounded, rather

broadly exposed ; disk with series of rather coarse, deep, moderately approxi-

mate punctures, the series scarcely at all impressed except very feebly toward

the suture; intervals each with a single even series of very fine punctures.

Abdomen finely, sparsely punctate, the prosternum very densely so. Legs

moderate, slender; basal joint of the hind tarsi slightly longer than the

remainder. Length 5.0 mm.; width 1.9 mm.

California.

The unique specimen is a female and it is possible that in the

male, the third antennal joint will prove to be quite distinctly

shorter than the fourth.

This species is decidedly aberrant in the form of the prothorax,

which is more subquadrate, in the smaller eyes and especially in

the arrangement of the elytral punctures. JI am however unable to

perceive any structural characters, which would warrant its removal

from the present genus. The maxillary palpi are of a common

form, the fourth joint being almost evenly recti-triangular, with the

oblique apex about equal in length to the outer side. )

MENGECEUS Champ.

Assuming M. crassicornis Champ. as the type of this genus, its

characters may be briefly stated as follows :—

Body oval, rather broad and moderately convex, the sides of the elytra con-

tinuous in curvature with those of the prothorax, the basal angles of the

latter acute and slightly produced posteriorly. Head small, short, deeply

inserted, vertical in repose, the fourth joint of the maxillary palpi very broad,

the apex nearly one-half longer than the outer side; terminal joint of the

labial short and robust. Antennz stout, the intermediate joints dilated in

Coleopterological Notices, IIT. 123

the male. Prosternal process horrizontal, tumid posteriorly, then abruptly

vertical and excavated to the level of the prosternal side-pieces. Legs and

tarsi throughout as in Hymenorus.

The general form of the body approaches some of the species of

Cistela or Isomira, but apart from the characters above mentioned

the genus is very closely related to Hymenorus. Some of the

species of the latter genus such as inqutlinus, fusicornis and

porosicornis are more or less allied to Meneceus, but the form is

narrower, the prothorax less transverse, and the basal angles not

posteriorly produced. This last feature constitutes really the only

important difference between Mencceus and Hymenorus.

- One species, which however differs from the typical form in

having the prosternal process and antenne as in Hymenorus, is

described in the Biologia by Mr. Champion from southern Texas ;

I have seen no representative of it, but the original description is as

follows :-—

M. texanus.—‘‘ Ovate, rather broad, piceous-brown, dull, thickly pubes-

cent. Head sparsely and rather coarsely punctured; eyes (% ) very large,

narrowly separated ; antenne (% ) stout, rather short, ferruginous ; prothorax

very broad, the disk obsoletely canaliculate behind, the surface closely (but

not densely), finely, and shallowly punctured ; elytra finely punctate-striate,

the interstices quite flat and finely and rather closely punctured ; legs ferru-

ginous ; the lateral lobes of the last ventral segment broad and spoon-shaped

and clothed with long hairs at the apex.’’ Length 74 mm.; width 3} mm.

This species is stated to be much broader than M. crassicornis,

with the pronotum more finely and sparsely punctured.

TELESICLES Champ.

This genus is very closely related to Hymenorus, the characters

throughout being similar, with the exception of the form of the

prothorax, the apex being transversely truncate and the sides con-

vergent toward base and feebly sinuate; this form is however so

radically different from anvthing known in Hymenorus, as to give

quite a distinct and peculiar habitus to the species of Telesicles,

and there can be but little doubt that the genus is a really valid

one. It is simply a good illustration of the statement made in the

introductory remarks to the present family, that generic differences

often depend ‘more upon general facies or appearance than upon any

decided modification of special organs.

124 Coleopterological Notices, IIT.

Our single species is as follows :—

T. cordatus Champ.—Biol. Cent.-Amer., Coleopt., IV, Pt. i, Nov. 1888,

p- 451.—Oblong, rather depressed, polished and pale ochreous-testaceous

throughout; pubescence rather short, semi-erect, coarse and sparse. Head

feebly convex, rather strongly, not very densely punctate; eyes small,-sepa-

rated by nearly one-half more than their own width; antenne slender, fili-

form, nearly one-half as long as the body, intermediate joints feebly obconieal,

about twice as long as wide, the third and fourth equal. Prothorax one-half

wider than long, the apex transversely truncate, four-fifths as wide as the

base, the latter transverse or just visibly, evenly arcuate throughout, the

sinuations obsolete; sides broadly arcuate, convergent in basal third and be-

coming strongly sinuate just before the basal angles, the latter right, some-

what prominent, not at all blunt; disk evenly convex, not impressed, rather

coarsely and sparsely punctate; basal fovee broadly impressed and alinost

obsolete. lytra about three times as long as the prothorax and one-fourth

wider than the disk of the latter, abruptly, acutely ogival at apex; sides

parallel and nearly straight; humeri narrowly rounded and quite broadly

exposed at base; disk with extremely feebly impressed series of rather coarse

deep punctures, which become much less distinct near the apex: intervals

flat, finely, confusedly and very sparsely punctate. Abdomen finely but dis-

tinctly, sparsely punctate. Legs rather short, slender, the basal joint of the

hind tarsi nearly as long as the remainder. Length 5.5-5.8 mm.; width

2,0—2.1 mm.

‘Texas (Hl Paso). Mr. Dunn.

There seems to be very little sexual difference, the eyes being just

visibly less distant in the male, and the fifth segment a little more

acutely rounded behind in that sex.

MYCETOCHARA! Berth.

Several attempts have been made to subdivide this genus but all

more or less unsuccessfully, for, although easily divisible into groups

by certain comparatively constant prosternal characters, it is found

that each group contains species which, in general habitus, are

strongly suggestive of homologous species in some of the others.

1 The correct designation of this genus is involved in considerable uncer-

tainty, and for this reason I at first determined to make use of the name given

in the Munich Catalogue, quite forgetting the familiar fact that Mycetophila

had been used by Meigen in 1803 for a genus of Diptera. The word here

adopted is that proposed by Seidlitz in the most recent edition of the “Pauna

Baltica,’’ and is considered by that author to be two years earlier than Myce-

tochares Latr., the former having been printed in 1827, while the latter was

not published in a properly latinized form until 1829.

Coleopterological Notices, IIT. 125

In other words each group is so heterogeneous, and the interos-

culating lines of affinity between them so numerous, that it seems

impossible to consider them as having full generic value.

The form and extent of the anterior coxe and of the prosternal

process which separates them, constitute the best characters for

minor subdivisions, for these appear to be the most constant within

the limits of the groups.

The fourth joint of the maxillary palpi is usually in the form of a

right-angled triangle, with the right angle at the point of attach-

ment, but sometimes the two sides form an angle which is slightly

less than right, the apex becoming shorter; it is generally quite

robust, but occasionally becomes decidedly slender. The eyes, tarsi

and antenne vary greatly in size and form in the various species,

and appear to be but slightly affected by sex.

The sexual differences are stated to be quite pronounced in many

of the European species, but in the North American they are cer-

tainly not remarkably so, and, as there is often much difficulty in

determining the sex of individuals, but little attention has been

given to this subject in the following descriptions.

The punctuation generally varies to a considerable degree, and

sometimes appears to be coarse or rather fine in the same individual

according to the direction of the reflected light; the elytra often

have to be held, therefore, in a very oblique position with reference

to the light, in order to see that the impressed lines, which are

nearly always distinct, are not accompanied by series of punctures

in such species as fraterna and nigerrima.

Our species may readily be separated into three groups as follows:

Anterior coxze rather small, separated by a comparatively wide prosternal

process, the latter longitudinally convex and attaining the level of their

Groups I and II both contain species with and without the red

the continent. Group III contains no species as far as known with

the humeral maculation, and is peculiar to the regions west of the

exactly, equivalent to those which have been indicated in the Huro-

The sexual differences appear to be exceedingly feeble.

This species is one of the smallest of the genus, and may readily

be known by its extremely sparse minute punctuation, almost in-

visible pubescence and absence of elytral series.

M. fraterma Say.—Journ. Ac. Phil., III, 1823, p. 270; laticollis Lec. :

Pr. Am. Phil. Soc., XVII, p. 617.—Oblong-elongate, subparallel, moderately

convex, piceous-black, the under surface, legs and antenne slightly paler,

piceous to rufo-ferruginous, each elytron with a large pale oblique spot from

near the suture to the humerus, polished ; pubescence fine, short, not very

dense and not conspicuous. Head feebly convex, rather finely, sparsely and

somewhat unevenly punctate; eyes moderate, separated by but slightly more

Pennsylvania; New York; Canada.

The description refers to the male which appears to be much

smaller and more slender than the female. In the latter sex the

antenne are relatively shorter and the prothorax is slightly more

transverse. Fraterna is more northern in its distribution than

haldemant.

I think that the unique specimen described by LeConte as lati-

collis is simply an extreme form of the female of this species. The

punctuation, especially of the head, is very uneven and quite vari-

able in fraterna, and there seemingly exists a most perplexing

plasticity in the form of the prothorax in some species—see remarks

under fenuzs. In fact I bave before me a normally punctate speci-

men of fraterna, in which the prothorax is somewhat dilated. and

rather wider than the elytra, just as in the type of latzcollis.

Although Melsheimer states that his ruficornis is distinct from

fraterna, I am inclined to think that it is nothing more than an

Coleopterological Notices, ITT. 129

immature specimen of this species, or at most a slight variety.

According to the description it is ‘brown, pubescent, densely punc-

tulate; antennz, labrum, palpi and feet testaceous; thorax at base

each side of middle with a small and profound impression; dorsal

impression obsolete; scutel brown; elytra densely rugulose; toward

the suture with faint traces of the interstices; base broadly and in-

determinately testaceous; beneath pale brown; femora rather pale

testaceous.”’ The punctuation of fraterna is sometimes strongly

rugulose, and, in regard to color, I have several specimens before me

of foveata, the normal color of which is black with pale humeri,

which have the elytra entirely pale from immaturity.

M. megalops n. sp.—Oblong-elongate, subparallel, rather depressed,

polished, black, the under surface piceous-black ; legs and antenne slightly

paler, piceous-brown, the latter paler toward base; pubescence moderate in

length, dark, recumbent, sparse and inconspicuous. Head feebly, longitudi-

nally convex, rather finely, densely punctate anteriorly, very sparsely and

unevenly so between the eyes, the latter extremely large and convex, separated

by about three-fourths their own width ; antenne robust, a little more than

one-third as long as the body, apparently very feebly attenuate toward apex,

the intermediate joints scarcely one-half longer than wide, third and fourth

equal. Prothorax nearly four-fifths wider than long, the apex scarcely two-

thirds as wide as the base, feebly arcuate; base transverse, the sinuations

very feeble, the angles slightly obtuse but not rounded; sides broadly rounded

and convergent anteriorly, less arcuate toward base; disk widest at about

basal third, convex throughout, almost completely unimpressed, very finely

and sparsely punctate. /ytra distinctly more than three times as long as

the prothorax and equal in width to the disk of the latter, parallel, rather

abruptly and obtusely rounded behind; disk somewhat strongly, asperately,

but rather sparsely punctate, without series but with the impressed lines dis-

tinct except toward the sides, with a vague appearance of punctured series

near the suture. Under surface finely, sparsely punctate throughout. Legs

normal. Length 4.0 mm.; width 1.5 mm.

Indiana? Cab. Levette.

The single specimen is a male, and is remarkable in having eyes

which are not only exceptionally large for the present genus, but in

proportion to the size of the body, fully as large as in any other

species of the family which I have seen. The elytra have, each, a

large oblique basal spot of a reddish-yellow tint, as usual in this

section of the genus. At first sight it resembles Hymenorus —

humeralis, but the tarsi are perfectly simple, the eyes large, the

pubescence dark, more recumbent and sparser, and the elytra are

devoid of distinct punctured series.

M. basillaris Say.—Journ. Ac. Phil., III, 1823, p. 269.

From the language employed by Say, it would seem as if this

species might be easily recognized if polaron but I have seen no

specimens.

Say’s description states that the head is punctured, the thorax

hardly punctured, with three indefinite indented lines on the poste-

rior margin; posterior angles rectangular; elytra with punctured

strie and interstitial lines; basal oval spot oblique; body dark

chestnut-brown, beneath paler. Length one-fifth of an inch.

Inhabits Pennsylvania.

M. tenuis Lec.—N. Spec. Col., 1866, p. 140.—Elongate, moderately con-

vex, subparallel, polished, piceous-black above and beneath ; legs pale flavate ;

antennz piceous, paler toward base; elytra each with a very small suffused

reddish spot just behind the humerus, which is sometimes wanting; pubes-

cence fine, rather short, very sparse and inconspicuous. Head evenly, feebly

convex, rather coarsely but sparsely punctate; eyes rather large and convex,

separated by nearly two-thirds more than their width; antenne rather slen-

der, not attenuate toward apex, a little less than one-half as long as the body,

the intermediate joints fully twice as long as wide, third distinctly longer

than the fourth. Prothorax about one-fourth wider than the head, two-fifths

wider than long, the apex three-fourths as wide as the base, subtruncate 5

base transverse, very feebly arcuate in the middle; sides parallel and nearly

straight from the base almost to apical two-fifths where they are broadly sub-

angulate and rounded ; basal angles right, not at all rounded, not depressed ;

disk feebly convex, more strongly so laterally toward apex, rather strongly

but very sparsely punctate throughout, not impressed in the middle, the basal-

fovee rather suffused but large and distinct. Llytra fully four times as long as

the prothorax, and, throughout, nearly two-thirds wider, somewhat strongly

narrowed behind in apical third; humeri rather broadly exposed, rounded ;

disk with somewhat vague, feebly impressed series of fine, feeble, not very

approximate punctures, the intervals having sparsely placed punctures which

are almost as large as those of the striw, arranged in rather uneven single

series. Under surface very finely, sparsely punctured throughout. Legs as

in gracilis. Length 5.2-6.0 mm.; width 1.7-1.9 mm.

New York; Ohio; Michigan.

This distinct species may be readily known by its slender form,

small head and prothorax, flavate legs and by its feebly marked

elytral series. In general form it approaches procera, but that

species has the prosternal process laminate.

little longer. As it is precisely similar to the normal forms in

every other particular, I am inclined to regard it as an accidental

variation.

M. foweata Lec.—N. Spec. Col., 1866, p. 140.—Elongate, suboval,

polished, moderately convex, piceous-black throughout, the legs and antennze

flavate; elytra sometimes testaceous throughout, but normally black, with a

small suffused subhumeral reddish spot; pubescence short, fine, extremely

sparse. dark and inconspicuous. Head suborbicular, feebly, evenly convex,

finely, sparsely punctate; eyes very small, not prominent, separated by nearly

four times their width; antenne somewhat robust, not attenuate, scarcely

two-fifths as long as the body, the intermediate joints strongly obconical,

about one-half longer than wide, third quite distinctly longer than the fourth.

Prothorax nearly one-half wider than the head, two-fifths wider than long,

the apex subtruncate, three-fourths as wide as the base, the latter transverse

and straight; sides strongly rounded at the middle, thence strongly conver-

gent and feebly arcuate to the apex, and distinctly convergent and broadly

sinuate to the basal angles, which are right and not at all rounded; disk

strongly declivous toward the apical angles, finely but deeply, distinctly,

sparsely punctate, narrowly, feebly impressed in the middle toward base;

basal fovee rounded, moderate in size, very deep and distinct. lytra a little

more than three times as long as the prothorax ; sides feebly arcuate; disk

slightly wider behind the middle, at base a little wider than the pronotal

disk, the humeri distinctly exposed, narrowly rounded; surface with feebly

impressed series of rather coarse, moderately close punctures, the intervals

each with a single series of very fine punctures. Abdomen very finely sparsely

punctate; anterior portions more coarsely but sparsely so. Legs moderately

slender, normal. Length 5.0-5.8 mm.; width 1.8-2.2 mm.

Michigan; Iowa; Indiana.

The sinuation of the sides of the prothorax is not always so

apparent as in the type, these often being convergent and straight

from near the middle to the base; it is more apparent in the large

specimens, and may therefore be more especially a female charac-

teristic. Otherwise there does not appear to be any noteworthy

sexual difference.

M. gilvipes n. sp.—Moderately robust and convex, suboval, polished,

black ; under surface dark rufo-testaceous, the legs flavate; antenne piceous-

black, paler toward base; each elytron with a large, clearly limited, oblique

basal spot, extending to internal third of the width ; pubescence rather long

and erect, but dark, sparse and inconspicuous. Head feebly convex, rather

coarsely but sparsely and feebly punctate; eyes rather small, separated by

scarcely three times their width ; antennz robust, the joints strongly obconi-

cal, generally about one-half longer than wide, the third much longer than the

fourth. Prothorax about one-third wider than long, the apex feebly arcuate,

sparsely punctate, the basal fovee small, deep and conspicuous. Elytra a

little less than three times as long as the prothorax, and, behind the middle,

about two-fifths wider; base slightly wider than the disk of the latter, the

humeri distinctly exposed; sides feebly arcuate behind, gradually and acutely

rounded at apex ; disk punctured and impressed nearly as in foveata. Under

surface very sparsely punctate, the abdomen minutely so. Legs rather short.

The single specimen serving as the basis of the above description,

represents a species closely allied to foveata, but distinguishable

more erect pubescence, slightly larger and more approximate eyes,

blackish antennse, much larger, more abruptly defined basal spots of

the elytra, and slightly coarser punctuation.

polished, intense black throughout above; legs and under surface piceous-

black, the tarsi paler; antenne pale brownish-testaceous throughout ; pubes-

cence fine, short, dark, very sparse and inconspicuous. Head feebly, evenly

convex, finely, very sparsely punctate; eyes rather small, separated by nearly

three times their width; antenne rather robust, barely more than one-third

as long as the body, scarcely attenuate toward apex, the intermediate joints

obconical, with the sides rounded, not quite one-half longer than wide, third

and fourth equal. Prothorax four-fifths wider than long, the apex broadly

arcuate, two-thirds as wide as the base, the latter transverse, with a small

feeble sinuations at each side of the middle; sides broadly arcuate through-

out, more convergent toward apex; basal angles obtuse and very narrowly

rounded; disk extremely minutely, sparsely punctate, barely perceptibly

impressed in the middle toward base, the basal fovee broadly impressed and

indefinite, but each apparently having a very small foveiform puncture in the

middle. Hlytra a little more than three times as long as the prothorax, and,

at the middle, scarcely visibly wider than the disk of the latter, gradually,

not very acutely rounded at apex; sides parallel and feebly arcuate; humeri

not exposed; disk finely, sparsely punctate, without series, the impressed

lines very feeble, but visible by obliquely reflected light, almost throughout the

sides subangulate at apical third, thence very feebly divergent and straight to

the basal angles, more strongly convergent and nearly straight to the apex ;

basal angles right, not rounded ; disk very feebly convex, except toward the

sides anteriorly where it becomes strongly declivous, rather finely but deeply,

distinctly, very sparsely punctate, the punctures becoming coarse and rather

dense laterally and anteriorly, broadly, strongly impressed along the middle

toward base, the basal fovee almost obsolete. Elytra about four times as long

as the prothorax, and, throughout, about three-fourths wider, parallel, the

humeri exposed and slightly rounded; apex rather gradually and acutely

rounded; disk with even series of small deep close-set punctures, the rows

Michigan (Marquette). Cab. LeConte.

The unique type has the partly concealed apical pseudosegment

narrow and strongly rounded at apex. I cannot determine its sex,

but it is probably a male.

This species somewhat resembles tenuzs, but may be aici diened

by its more robust form, larger eyes, more distinct elytral series,

absence of humeral pale spot and several other characters.

The unique type represents a very isolated species, not remotely

approaching any other, although in general somewhat recalling

marginata of the next group. I do not know the sex of the speci-

men described, but it is apparently the female.

Michigan (Marquette); New York.

The anterior coxal cavities are by no means confluent as stated

by LeConte (N. Spec. Col., 1866, p. 138, foot-note), but the thin

lamina separating them is almost completely hidden below and

between the unusually large and prominent coxe. This lamina

gradually becomes broader behind, and widely separates the side-

pieces of the prosternum at the posterior margin; it is on the same

level as the latter throughout its length.

Michigan (Detroit). Cab. LeConte.

The prothorax in general outline is similar to the prevailing type

in Hymenorus. The anterior coxe are large, subcontiguous, conoi-

dal and prominent, the cavities separated by a very narrow lamina,

apparently horizontal and almost completely concealed by the coxe.

This species is quite isolated, although bearing a remote general

resemblance to several others such as tenuis and procera. It is

represented, as far as known to me, only by the original unique type,

taken by Mr. Schwarz.

This is a remarkably distinct species, immediately recognizable

by the smooth, highly polished, minutely, sparsely punctate surface

and deeply impressed, almost sulciform elytral striz. The maxil-

lary palpi do not differ much from those of lugubris and analis.

The narrow lamina separating the anterior coxee is convex longi-

tudinally, but comes far from attaining the level of the coxal apices.

This species is closely allied to /ugubris, but may be distinguished

by its slightly smaller eyes, the unexplanate sides of the prothorax,

and more feebly impressed, less conspicuously punctured and more

uneven elytral striz, as well as by its rather larger size and more

robust form.

One specimen before me, from New York, is black above and

piceous-black throughout beneath, and, as I notice a few other

slight differences, it may possibly indicate a variety.

The maxillary palpi are rather shorter and thicker than in lugu-

bris, the recti-triangular fourth joint being but slightly longer than

wide.

Idaho; California (Los Angeles).

The last joint of the maxillary palpi is moderately robust, scarcely

twice as long as wide, the two sides making an angle of about sixty

degrees at base, the inner about one-half as long as the outer and

three-fourths as long as the apex. The anterior coxe and extremely

thin prosternal lamina are nearly as in longipennis, from which the

present species can at once be known by its more slender depressed

form, small head and prothorax and long posterior tarsi, with un-

usually short basal joint.

The specimen from California has the head, and to some extent

also the prothorax, much more densely punctate than that from

Idaho, and the head is a little larger in the former. These differ-

ences are probably in great part sexual, and I think generally but

little reliance is to be placed upon degree of punctuation in the

present genus. The genera with lobed tarsi are much more con-

stant in specific characters.

Nevada (Reno).

This species belongs to a small croup peculiar to the Pacific coast,

including also pubipennis and crassulipes; it is readily distinguish-

able from either of these by its much broader form, more transverse

prothorax, distinctly larger eyes and complete absence of punctured

series. One specimen has two discal fovez on the prothorax, of an

adventitious nature, similar to those which appear occasionally

throughout the Tenebrionids. The coxe are similar to those of

pubipennts, but the palpi are rather shorter and more robust.

slightly before the middle than at base, not noticeably impressed in any part,

somewhat coarsely and sparsely punctured, the basal fovez entirely obsolete.

Elytra between three and four times as long as the prothorax, and, at the

middle, nearly one-half wider, gradually, evenly ogival at apex; humeri

narrowly rounded, rather broadly exposed, the width at this point distinctly

greater than that of the pronotal disk; sides feebly but distinctly arcuate

throughout; disk rather finely, sparsely and confusedly punctate, with feebly

impressed lines and series of punctures toward the suture only. Under surface

finely, sparsely punctate. Legs short and unusually robust, the hind tarsi

much shorter than the tibiz, with the basal joint not more than three times

as long as wide, and but little longer than the next two. Length 4.0 mm.;

width 1.6 mm.

California (Hoopa Valley, Humboldt Co.).

Kasily distinguishable from pubipennis by its pale color, smaller,

more cordate and unimpressed prothorax, much shorter, more robust

antennal joints, pale shorter and coarser pubescence, sparser punc-

tuation and shorter more robust legs and tarsi. The unique speci-

men is a female and the before described type of pubipennis is also

of that sex.

ISOMIRA Mauls.

Although the species here assigned to Isomira have a community

of habitus which decidedly indicates the propriety of associating

them together, it is difficult to state any absolutely definitive struc-

tural characters. The maxillary palpus varies, in its terminal joint,

from the slender form seen in sericea, through the rather broadly tri-

angular of pulla, to the form seen in quadristriata. The antenne

have the third and fourth joints equal in rather more than half the

species, but in*the remainder the former is much the shorter of the

two, sometimes approaching the form seen in Cistela and the Euro-

pean antennata. ‘The elytra may be almost completely devoid of

impressed striz, or may have more or less feebly impressed rows of

punctures as in valida, tewana and many of the Central American

forms.

The only character which satisfactorily distinguishes the genus

from Cistela, apart from the very pronounced peculiarity of facies,

appears to be the slender filiform antenne, a differential character

corresponding with that made use of by Mr. Champion for the

separation of Allecula and Hymenorus.

Our species are found on foliage of low plants and are moderately

abundant. They are easily differentiated as follows :—

Iowa.

The single specimen before me seems to be slightly immature.

The maxillary palpi are nearly as in sericea, but with the inner

angle of the terminal joint rather more broadly rounded.

This is a rather isolated species, at once distinguishable by its

large eyes, strongly impressed front, sparse punctuation and antennal

‘structure.

I. discolor n. sp.—Elongate-elliptical, moderately convex, rather strongly

shining, piceous-black, the antenne and legs throughout concolorous ; pro-

notum and prosternum pale ferruginous ; pubescence fine, very short, sparse.

California.

This is our smallest species, and is very distinct in its coloration

and sparse, coarse punctuation, as well as in antennal structure.

The head is distinctly shining, the comparatively wide interspaces

of the punctures being polished. The abbreviated third joint of the

antenne is probably not altogether a sexual character.

I. tenebrosa n. sp.—Elongate-elliptical, strongly convex, extremely

finely and densely punctate and pubescent, rather dull and subsericeous,

piceous-black ; legs and antennez paler. Head feebly convex, the punctures

densely crowded ; eyes rather small; antenne filiform, moderate in length,

in the male scarcely more than one-half as long as the body ; joints slightly

shorter in the female. Prothorar about two-fifths wider than long, the apex

more or less strongly arcuate, and generally continuous in curvature with the

sides, the latter parallel and nearly straight toward base; basal angles slightly

obtuse and rather distinctly rounded; base transverse, just visibly arcuate in

the middle; disk very finely, extremely densely punctured, feebly impressed

in the middle toward base, the basal fovee broadly impressed along ‘the mar-

gin, feeble. lytra three times as long as the prothorax, and, at the middle,

New York (near the city and at Buffalo).

This species is quite slender, nearly similar in shape, and in its

extremely dense punctuation, to sericea; it differs in its much

smaller size, dark piceous-black color, shorter antenne, slightly

smaller eyes and still more decidedly in the form of the fourth joint

of the maxillary palpi, which is here very slender, twice as long as,

and not quite one-half wider than, the third, with the inner side

three-fourths as long as the outer and much longer than the apex,

the latter much less oblique and narrower than in any other species.

densely punctate, feebly, evenly convex ; eyes moderate; antenne long and

slender, filiform, nearly two-thirds as long as the body, with the third and

fourth joints equal in both sexes. Prothorax one-half wider than long, the

sides rounded anteriorly, nearly straight and parallel in basal half; apex

about two-thirds as wide as the base, feebly arcuate; base transverse, broadly,

feebly arcuate in middle half, the angles right, not rounded; disk dull, punc-

tured like the head, the basal fovex shallow but rather distinct. Llytra nearly

four times as long as the prothorax, and, in the middle, about one-third wider,

between the narrowly rounded humeri very slightly wider than the thoracic

base, rather acute at apex, the disk somewhat more shining than the anterior

portions, but exceedingly densely, finely punctured, with three or four feeble

impressed stri# near the suture, more strongly marked toward apex, the strie

where more deeply impressed becoming also very minutely punctate, elsewhere

without trace of serial punctuation. Under surface decidedly more shining,

the abdomen very minutely, feebly and densely punctate, the anterior portions

more coarsely and rather densely so. Jegs rather long, very slender ; poste-

rior tarsi a little shorter than the tibise, with the first joint three-fourths as

long as the next three.

Male.—Eyes separated by three-fourths more than their own width; fifth

ventral slightly longer and less truncate than in the female, more or less

feebly impressed.

Length 4.8-5.5 mm.; width 1.9-2.3 mm.

Massachusetts; North Carolina.

The last joint of the maxillary palpi is about twice as long as the

third, and about one-half wider, with the inner side one-half as long

as the outer, the apex obliquely truncate. In the female the eyes

are but slightly smaller than in the male, and the joints of the

antenne a very little shorter and thicker. This is the most abun-

dant of our eastern species.

I. variabilis Horn.—Trans. Am. Ent. Soc., Sept. 1875, p. 156.—Oval,

narrowed from base to apex, the latter scarcely more than one-half as wide as

the base, feebly arcuate; sides broadly rounded anteriorly ; base transverse,

the sinuations broad and very feeble; disk extremely densely and rather finely

punctate, the basal fovez broadly impressed and feeble. lytra about three

and one-half times as long as the prothorax, and, near the middle, from one-

third to one-half wider, not very acutely rounded at apex; disk very finely,

punctured. Legs slender, generally pale.

Male.—Kyes separated by about three times their width.

Length 4.3-5.9 mm.; width 1.8-2.3 mm.

California; Washington State.

In both male and female the third and fourth joints of the

antenne are long, slender and equal, and the joints throughout are

but slightly shorter and thicker in the latter sex. The maxillary

palpi are nearly as in sericea.

The large series before me is exceedingly heterogeneous, not only

in color, but in general habitus, there being some specimens which

are broad, short and strongly convex, with the prothorax large and

at the base as wide as that of the elytra, and others which are

comparatively narrow, elongate and depressed, with the prothorax

much smaller. These differences seem to be independent of sex,

and surely indicate a mixture of closely related but distinct forms,

which the amount of material before me will not suffice to elucidate ;

especially as there is marked uniformity in the antenne, sculpture

and other structural characters throughout the series.

I. Ruscitiosa n. sp.—Rather narrowly oval, generally slightly broader

behind, dull, the elytra shining, dark piceous-brown throughout, the anterior

portions blackish; pubescence fine, short, moderately dense. Head feebly,

evenly convex, very densely, rather coarsely punctate; eyes very small and

unusually convex; antenne slender, filiform, three-fifths as long as the body.

Prothorax nearly three-fourths wider than long, the sides broadly rounded,

almost straight and parallel toward base; apex avout two-thirds as wide as

the base, feebly arcuate; base transverse, the sinuations broad and very

feeble ; disk extremely densely punctate, the punctures rather coarse; basal

foveze widely impressed and feeble. lytra about three times as long as the

prothorax, and, at or behind the middle, nearly one-half wider, the two bases

equal; apex rather abruptly but acutely rounded; disk finely but distinctly,

not extremely densely punctate, without trace of impressed strie or series

except the usual two near the suture, which are fine but deep toward apex.

Abdomen polished, very finely, rather sparsely punctate, the prosternum duller

and densely, more coarsely so. Legs slender, moderate in length, the basal

joint of the hind tarsi distinctly shorter than the remainder.

Male.—Third and fourth joints of the antennz equal, each nearly twice as

long as the second ; eyes separated by about four times their own width.

the same time more convex and prominent eyes.

It is represented by two specimens collected by Mr. Albert

Koebele.

I. pullla Melsh.—Proc. Ac. Phil., III, p. 60.—Elliptical, convex, the

elytra generally slightly wider behind, piceous-black throughout, the tarsi

and sometimes the tibiw, prosternum and a feebly marked narrow sutural

line slightly testaceous ; surface slightly shining, the pubescence very short

and dense. Head finely, very densely punctate, the surface almost flat; eyes

rather small; antenne slender, about one-half as long as the body, the third

and fourth joints subequal in both sexes. Prothorax about three-fourths wider

than long, strongly narrowed from base to apex, the sides almost evenly arcu-

ate ; apex scarcely more than one-half as wide as the base, feebly arcuate ;

base transverse, scarcely visibly arcuate toward the middle, the angles right,

not distinctly rounded ; disk very vaguely and broadly impressed along the

middle, sometimes only near the base, the punctures fine but deep, distinct,

and almost in mutual contact; basal fovee very feeble, short and extending

slightly along the basal margin. lytra but slightly more than three times

as long as the prothorax, and, behind the middle, nearly two-fifths wider, at

base equal in width to the thoracic base; apex moderately acute; disk punc-

tured and with subsutaral strie nearly as in sericea, the punctures slightly

coarser and a little sparser. Under surface rather shining, the abdomen very

minutely, feebly and somewhat sparsely punctate. Legs nearly as in sericea

but rather shorter.

Male.—Kyes separated by about three times their own width.

Length 4.9-5.3 mm.; width 2.1-2.3 mm.

Rhode Island; North Carolina.

The terminal joint of the maxillary palpus is rather short and

robust, much less than twice as long as the penultimate, with the

inner side nearly three-fourths as long as the outer. In this respect,

as well as in the much smaller eyes, the present species is inter-

mediate between sericea and quadristriata.

The antenne do not differ greatly in the sexes, and are distinctly

shorter and a little thicker than in sericea. As in nearly all the

darker species the entire body is frequently paler from immaturity.

This species makes the nearest approach to the Kuropean murina,

but has the pronotal punctuation distinctly coarser and less dense ;

in fact we have no species in which the punctuation of this part is

SO excessively fine and densely crowded as in murina.

differing in the female.

Length 5.0-5.8 mm.; width 2.1-2.8 mm.

Canada; Lake Superior; North Carolina.

A widely diffused and common northern species, distinguishable

by its rather sparse punctuation and the sides of the prothorax more

strongly rounded toward base, so that in some specimens the disk

is distinctly widest before the base. The male is notably narrower

than the female. The terminal joint of the maxillary palpi is broad,

and the outer side is scarcely longer than the apex.

The single male which I took in North Carolina is decidedly

shorter and broader than another male taken in Rhode Island, and

the sides of the prothorax near the base much less rounded, in fact

almost straight and parallel; it may possibly be a variety.

The disk of the prothorax is less convex toward the sides than

in the species allied to serzcea, and there are generally two feebly

impressed discal foveze and a feeble median impression near the base.

punctate. Legs slender, the basal joint of the hind tarsi three-fourths as long

as the remainder.

California (Lake Tahoe).

This species is distinct in facies, resembling only oblongula in this

respect. It differs however from oblongula in many characters

besides those mentioned in the table, as may be inferred from the

description. The single specimen appears to be a female, although

it is impossible to state this definitely without dissection. From

quadristriata it differs in its more elongate form, larger prothorax,

which is much more nearly equal in width to the elytra, and in the

shorter third joint of the antenne.

I. oblongula n. sp.—Oblong, rather elongate and subparallel, convex,

blackish piceous throughout, the legs and antenne concolorous ; tarsi slightly

paler; suture feebly, narrowly rufescent ; pubescence very short, dense, pale

and conspicuous. Head feebly convex, finely, densely punctate, the punctures

distinctly separated; eyes large; antenne very slender, filiform, rather more

than one-half as long as the body. /Prothorax fully three-fourths wider than

long, the apex subtruncate, scarcely two-thirds as wide as the base, the latter

transverse, the lateral sinuations broad and almost obsolete; basal angles

very slightly obtuse, not rounded; sides broadly arcuate throughout, more

strongly so and convergent anteriorly ; disk slightly wider at basal third than

at base; convex, finely, extremely densely punctate, very feebly impressed in

the middle near the base, the basal fovexw widely, feebly impressed and incon-

spicuous. Jlytra fully four times as long as the prothorax, and, at the middle,

about one-third wider, ogival at apex; humeri slightly and arcuately oblique

externally, not at all exposed at base; sides very feebly arcuate; disk with

rather distinct but very feebly impressed lines throughout the width, finely,

densely punctate, without punctured series. Abdomen minutely, somewhat

densely punctate, polished ; propleure very sparsely so externally. Legs long

and slender, normal.

the fourth. The eyes are separated by scarcely one-third more

than their own width. The fourth joint of the maxillary palpi is

rather robust, the inner and outer sides making an angle at the base

of nearly ninety degrees, the former about one-half as long as the

latter, the outer side but slightly longer than the apex which is

feebly arcuate.

There is no species here described which is closely allied to this,

but the form of the maxillary palpi shows that it should be placed

in the neighborhood of quadristriata.

separated, feebly impressed just before the scutellum; basal foveze almost

obsolete. Elytra nearly four times as long as the prothorax, and, at the

middle, about one-fourth wider, gradually and rather acutely rounded behind,

disk rather finely, densely punctate, with series of almost similar punctures

which are completely unimpressed, except the two or three sutural toward

apex. Abdomen finely, densely punctate; metasternum very sparsely so;

propleure and prosternum again more densely so. Legs slender, the first joint

of the hind tarsi very nearly as long as the remainder.

This is one of the few tropical types which extend into our

fauna from Central America, where they constitute a characteristic

element of the genus. It is readily distinguishable by its unusually

large eyes and completely unimpressed elytral series.

This species is allied to valida, but easily distinguishable by its

more oblong parallel form, longer prothorax, larger head, smaller

and more distant eyes, more distinctly impressed elytral series, and

more sparsely punctate abdomen.

The maxillary palpi are nearly as in valida, the last joint about

twice as long, but scarcely twice as wide as the penultimate, the

outer side about one-fourth longer than the apex, the inner side a

little more than one-half as long as the outer.

moderate in length, very slender, the external side feebly, evenly arcuate, the

internal pectinate in apical two-thirds, the denticles very fine, short, five or

six in number. Genital armature of the male deeply bilobed.

This genus while more closely allied to Isomira than to any other

here noticed, possesses also many elements suggestive of Capnochroa

and Andrimus, especially the general form of the body, and the

dilated anterior tarsi of the male. The coarser sculpture of the

upper surface and slightly exposed humeri, are also characters

reminding us of Andrimus, while the form of the head and tendency

to obliteration of the elytral striz are characteristic of Isomira.

The genital armature of the male is similar to that of the latter

genus.

J have seen only a single species which may be defined as follows:

with series of small approximate punctures, which are obliterated and con-

fused with those of the intervals except toward the suture, the series extremely

ANDRIMUS n. gen.

Cteniopus Lec. nec Sol.

The principal characters of this genus may be stated as follows :—

Front not noticeably prolonged. Antenne differing in the sexes, much

longer, more broadly compressed, and with the joints more strongly obconical

in the male, filiform in the female, the third joint much shorter than the

fourth in both sexes. Eyes moderate in size, but convex and prominent, the

inner margin very broadly rounded. Maxillary palpi with the fourth joint

rather slender, the angle at the base much less than right, the inner side

distinctly shorter than the apex, slightly more robust in the male, with the

apex longer and sometimes nearly as long as the outer side. Labial palpi

with the third joint slender, twice as long as wide, the apex truncate and but

slightly oblique. Mandibles truncate at apex, the truncation slightly oblique

and very obsoletely, broadly emarginate, the upper lobe twice as wide as the

lower, longer and more advanced. Anterior coxe separated by a process simi-

lar to that of Cistela but a little narrower, the posterior separated by a slender

acute abdominal process. Legs rather short, the tarsi shorter than the tibia,

the anterior feebly dilated in the male; ungues rather long and slender, with

five or six denticles in apical two-thirds only, the basal third not pectinate.

Genital armature distinct in both sexes, broadly sinuato-truncate at apex in

the male, more narrowly and deeply sinuate in the middle in the female.

In the form of the mandibular apices this genus is intermediate

between Cistela and Androchirus, but differs from both in the much

feebler emargination. In its slightly dilated anterior tarsi of the

male it is between Capnochroa and Tedinus. In the form of body

in many of the species, which is oblong-oval, subparallel and but

feebly convex in a longitudinal direction, in the aspect of the head,

and in the general nature of the sculpture and vestiture it strongly

resembles Mycetochara.

The elytra are generally abruptly wider at base than the protho-

rax, and are gradually, narrowly dehiscent toward apex from near

the middle; the surface is striato-punctate and the pubescence is

quite peculiar, consisting of longer erect hairs, with others that are

shorter and more recumbent. In this last character Andrimus

differs radically from Cistela, but in Capnochroa it is feebly indi-

eated by viewing the elytra tangentially, when the surface will be

found to be sparsely strewn with short erect hairs in addition to

156 Coleopterological Notices, ITI.

the ordinary subrecumbent pubescence. In the form of the genital

armature this genus differs greatly from any of those allied to

Cistela, for in the male this part is not at all bilobed, and, what is

still more exceptional in the family, it is more strongly sinuate at

apex in the female than in the male; it is almost equally exposed

and prominent in both sexes.

This genus differs from the European Cteniopus in having the

anterior coxe more widely separated, in the short third antennal

joint, in its unextended front, and in the longer basal joint of the

hind tarsi.

Andrimus will probably prove to be a moderately large genus in

our Gulf States, but the species are rather closely allied among

themselves, and may be difficult to discriminate from description,

especially as there is nearly always more plasticity and specific

variability in the genera with non-lobed tarsi, than in the others.

The material which I have examined indicates five species, appa-

rently without much doubt; these may be distinguished by the

following characters :—

A. murrayi Lec.—New Spec. Col., 1866, p. 141 (Cteniopus).—Oblong-

oval, shining and rather pale piceous-brown throughout; pubescence rather

long, semi-erect and sparse on the elytra. Head nearly flat above, with a

transversely oval, deep impression involving the base of the epistoma and

margin of the front; surface rather finely but deeply, somewhat densely punc-

tate, the punctures all distinct ; eyes separated by their own width, bordered

internally by a fine groove; antenne scarcely one-half as long as the body,

slender, filiform, the third joint much more than twice as long as the second

and fully three-fourths as long as the fourth. Prothorax three-fifths wider

than long, rather campanulate in form, the basal angles right but distinctly

prominent laterally, the sides before them at first feebly sinuate then nearly

straight and parallel to anterior two-fifths, then strongly rounded to the apex

which is truncate and two-thirds as wide as the base, the latter transverse,

the sinuations rather narrow and feeble; disk almost evenly convex, finely,

sparsely punctate, with a narrow impunctate median line; basal fovee small

but distinct. Llytra between four and five times as long as the prothorax,

and, at the middle, about one-half wider, strongly dehiscent in apical third,

ogival at apex ; sides parallel, feebly arcuate, the humeri strongly rounded to

the base of the prothorax and somewhat widely exposed ; disk with series of

rather small, close-set punctures, the rows almost completely unimpressed,

except feebly near the suture; intervals finely, sparsely, confusedly punc-

tate. Abdomen minutely, extremely sparsely punctate. Zegs rather short and

moderately slender, the tarsi all much shorter than the tibie, the basal joint

of the posterior a little shorter than the remainder. Length 9.8 mm.; width

3.7 mm.

Florida. Cab. LeConte.

The description is taken from the unique female type, and I have

seen no other specimen which can be placed with it.

The lateral prominence of the basal angles of the prothorax is a

eharacter which is probably quite variable in degree, and has been

noticed by Champion in one of the Central American species of

Lobopoda.

The type is the largest specimen of the genus which I have seen.

The genital armature is narrowly and rather deeply sinuate in the

middle at apex, the sinus and apices being about equal in curvature.

The fifth ventral segment has, near the apex, a deep transversely

oval, abruptly limited excavation.

A. brunneus n. sp.—Brown, polished throughout, strongly convex,

sparsely pubescent. Prothorax from one-third (male) to one-half (female)

wider than long, the sides parallel and straight in basal two-thirds, then

rounded to the apex; disk evenly convex, finely but deeply, rather sparsely

punctate, without an impunctate median line except near the base; basal

fovez almost completely obsolete.

Male.—Hlytra four times as long as the prothorax, and, in the middle, about

one-third wider, the humeri very narrowly exposed at base; eyes separated

by their own width ; antenne two-thirds as long as the body, the joints rather

strongly obconical, a little more than twice as long as wide, the third one-half

longer than wide and about one-half as long as the fourth; anterior tarsi

quite distinctly dilated, subequal in length to the tibia, the basal joint nearly

as long as the next two combined ; fifth ventral segment short and broad, not

longer than the fourth, very broadly, evenly rounded at apex, the surface not

at all impressed; genital armature finely punctate, broadly truncate at apex,

the truncation broadly, very feebly, evenly sinuate throughout, the angles

obtuse and distinct but slightly rounded; intromittent organ long and very

slender.

Female.—Elytra distinctly more than four times as long as the prothorax,

and, behind the middle, nearly one-half wider, the humeri very narrowly

exposed at base; eyes separated by slightly more than their own width;

antenne rather more than one-half as long as the body, slender and filiform,

the third joint nearly twice as long as wide and three-fifths as long as the

fourth ; anterior tarsi slender, much shorter than the tibie; fifth ventral

segment short, broadly arcuate at apex, the surface broadly, indefinitely im-

pressed ; genital armature sinuate at apex, the lateral angles broadly rounded.

Length 7.3-8.5 mm.; width 2.6-3.2 mm.

Florida (Haulover). Mr. Schwarz. National Museum.

When compared with the female of murrayi, the corresponding

sex of this species differs in its longer antenne with shorter third

joint, in the less exposed elytral humeri, in the widely diffused im-

pression of the fifth ventral segment, in the broader, feebler median

sinuation of the genital armature, and in its smaller size. The

elytra of murrayi are more strongly dehiscent toward apex, and

have the sides parallel, so that they are widest at about the middle,

while in the present species they are subinflated behind the middle,

the sides being more convergent toward base.

A. concolor n. sp.—Oblong-oval, rather strongly depressed, brown and

polished throughout ; pubescence sparse.

Female.—Head rather strongly and densely punctate, with a distinct median

longitudinal sulcation ; eyes moderate, separated by fully two-fifths more than

their own width; antenne scarcely one-half as long as the body, slender,

filiform, the third joint but slightly longer than the second and one-half as

long as the third. Prothorax one-half wider than long; sides parallel and

nearly straight in basal three-fifths, then somewhat abruptly convergent and

feebly arcuate to the truncate apex; basal sinuations very feeble, the broadly

rounded median lobe more prominent posteriorly than the lateral portions ;

basal angles right and distinctly blunt; disk almost evenly but feebly con-

vex, with a very imperfectly defined median impunctate line, very finely,

sparsely punctate, the basal fovez almost obsolete. lytra fully four times

as long as the prothorax and about one-half wider, rather obtusely ogival in

apical third and gradually strongly dehiscent; sides parallel and very feebly

arcuate behind, straight toward base, the humeri rather broadly exposed ;

disk rather strongly flattened toward the suture, the first three or four striz

distinctly impressed ; strial punctures fine; intervals finely, unevenly and

sparsely punctate. Abdomen very minutely, extremely sparsely punctate.

Legs rather short, the tarsi about as long as the tibia; basal joint of the

posterior quite distinctly shorter than the remainder. Fifth ventral segment

short, broadly, indefinitely but strongly impressed ; genital armature sinuate

in the middle, nearly as in brunneus.

Length 8.5 mm.; width 2.9 mm.

This species is distinguishable at once from murrayt by the very

short third antennal joint of the female, and from brunneus by its

much narrower, more depressed form and smaller eyes of the same

sex. There is before me a male which should apparently be asso-

ciated with the female type above described, being depressed and

nearly similar in size and outline. The pronotum of this specimen

is strongly alutaceous and dull, and has two extremely large and

deep discal foveve, probably of an accidental nature; the antenne

are but slightly more than one-half as long as the body, but stout,

compressed, with the joints much more strongly obconical, the third

joint scarcely one-half as long as the fourth.

A. nigrescens n. sp.—Oblong-oval, rather strongly. convex, piceous-

black throughout, the antenne black; tarsi rufescent; integuments shining ;

pubescence sparse.

Male.—Head rather finely but deeply, very densely punctate; eyes promi-

nent, separated by their own width ; antenne long, stout, strongly compressed,

fully two-thirds as long as the body and subequal in length to the elytra,

joints strongly obconical, scarcely more than twice as long as wide, the third a

little longer than wide and less than one-half as long as the fourth. Prothorax

rather long and subquadrate, one-third wider than long; sides parallel and

straight in basal two-thirds, then evenly, strougly rounded to the truncate

apex ; base transverse, the sinuations narrow and feeble; basal angles right,

blunt; disk rather convex, finely punctate, the punctures sparse but denser

_ toward the middle anteriorly, with a feeble impunctate line toward base;

basal fovee small and distinct. Llytra unusually short, twice as long as wide,

one-half wider and not quite four times longer than the prothorax, narrowly,

gradually dehiscent from the middle, the sides in basal two-thirds parallel

and feebly arcuate; humeri broadly exposed at base; disk with rows of rather

small punctures, deep and conspicuous except toward the sides, where they

become very fine, the striz more or less strongly impressed throughout the

width ; intervals finely, confusedly and not very sparsely punctate. Aldomen

wanting in the type. Jegs rather short, the anterior tarsi dilated, the poste-

rior scarcely three-fourths as long as the tibiw, with the basal joint much

shorter than the remainder. Length 8.0 mm.; width 3.0 mm.

Florida. Mr. Jiilich.

The principal differences between this species and the male of

brunneus reside in the broader, relatively longer and more com-

pressed antenne, which are black in nigrescens and pale brown in

brunneus, in the broader, relatively shorter elytra and much shorter

tarsi. In the male of brunneus the hind tarsi are very nearly as

long as the tibie. From the male of concolor it differs in its convex

form and much longer antenne. With the female type of murrayt

it has very little in common.

A. convergens n. sp.—Rather slender, moderately convex, piceous ; legs

and elytra dark brown; integuments polished throughout ; pubescence sparse.

160 Coleopterological Notices, ITT.

Male.—Head somewhat concave between the eyes, rather coarsely, sparsely

and unevenly punctate; eyes somewhat large, separated by three-fourths of

their own width; antenne moderately stout and very feebly compressed, two-

thirds as long as the body, the joints distinctly more than twice as long as

wide, the third one-half as long as the fourth. Prothorax scarcely one-half

wider than long, slightly wider at anterior third than at base, the sides from

that point feebly convergent and straight to the basal angles, the latter right

and narrowly rounded; base transverse and straight in middle half, feebly

posteriorly oblique laterally ; apex truncate, two-thirds as wide as the base,

the sides in apical third rather strongly convergent and feebly arcuate; disk

rather finely, sparsely, somewhat unevenly punctate, with an impunctate

median line; basal fovee small but deep and very conspicuous. Elytra two-

fifths wider than the prothorax and rather more than four times as long ; sides

parallel ; humeri rather broadly exposed at base ; disk punctate and striate as

in concolor. Abdomen minutely and very sparsely punctate throughout. Legs

somewhat short; all the tarsi distinctly shorter than the tibie, the anterior

subdilated, the basal joint of the posterior two-thirds as long as the remainder.

Fifth ventral segment but slightly longer than the fourth; broadly rounded

behind, the genital armature broadly sinuato-truncate at apex. Length 7.3

mm.; width 2.5 mm.

New York.

The specimen before me is labeled as above, but there is more

or less doubt concerning such a northern habitat. The species is

quite distinct from the others in the decidedly larger eyes of the

male, and the sides of the prothorax convergent and straight from

before the middle to the base, also in its minute but unusually deep

basal foveee of the pronotum.

CAPNOCHROA Lec.

This is also an exclusively American genus, and is represented in

our fauna as far as known by a single large and interesting species.

It is not very closely related to Cistela, although the mandibles

are notched at apex and subequally bilobed as in that genus. The

sexual characters differ greatly, and the anterior tarsi instead of

being strongly compressed and distorted—when modified at all in

the male—are here long and slender, and feebly flattened or just visi-

bly dilated, with the basal joint as long as the next two together, in

this character approaching Andrimus (Cteniopus Lee.) and Tedinus.

In the great development of the lobes of the male genital arma-

ture, it resembles Androchirus and differs completely from Andri-

mus. The unusually composite nature of Capnochroa will therefore

be recognized at once.

The maxillary palpi differ somewhat conspicuously in the sexes,

the fourth joint being more elongate in the male, with the inner

side much shorter than the apex; in the female the inner side is

subequal to the apex. Less marked sexual differences in the palpi

are observable also in some other genera, such as Isomira and the

Huropean Cteniopus, this character apparently being especially

developed in the genera with simple tarsi.

Some of the Central American species assigned to Cistela by Mr.

Champion, are said to have the anterior tarsi more or less dilated,

and these may possibly find a more fitting place as a separate genus

allied to the present one, but differing in the serrate antenne. Cvs-

tela fragilicornis should, almost undoubtedly, be placed in Cap-

nochroa.

C. fuliginosa Melsh.—Proc. Ac. Phil., III, 1846, p. 59.—EHlongate-ellip-

tical, strongly, very gradually pointed behind, moderately convex, dark piceo-

eastaneous throughout, dull, the elytra polished ; pubescence extremely short,

dense on the pronotum, sparse on the elytra. Head finely, rather densely

punctured, the eyes moderate; antenne long, rather slender, feebly com-

pressed, filiform. Prothorax from three-fourths wider, to nearly twice as wide

as long, the apex less than one-half as wide as the base, truncate; base trans-

verse, broadly, rather feebly bisinuate, the basal angles right; sides parallel

and nearly straight in basal half, then very strongly convergent and broadly

arcuate to the apex; disk very feebly convex, more or less explanate laterally,

very finely but strongly, densely punctate, the punctures distinctly but nar-

rowly separated; basal fovee small but distinct. lytra feebly, gradually

dehiscent toward apex, rather more than four times as long as the prothorax,

and, in the middle, quite distinctly wider, very gradually acute behind, each

elytron narrowly rounded at tip; sides broadly, feebly arcuate, the humeri

obliquely rounded to the base of the prothorax; disk with fine, deeply

impressed series of moderately fine distinct punctures, the intervals con-

vex, minutely and not very closely, confusedly punctate. Abdomen polished,

minutely, rather sparsely punctate, somewhat more closely so toward the

middle in the male. Legs and tarsi long, very slender in both sexes, the basal

joint of the posterior as long as the remainder.

Male.—Kyes separated by just visibly less than their own width; antennze

two-thirds as long as the body, the fourth joint fully twice as long as the two

preceding together, third slightly longer than wide; anterior tarsi longer than

the tibie, extremely feebly dilated, densely clothed beneath with short flavate

hairs which bristle laterally in the form of fimbrie; fifth segment with a rather

small median sinuation which is much wider than deep, the edge bordering

it strongly inflexed; genital armature deeply bilobed, the lobes large, long,

flattened, slightly twisted but not bent downward, excavated along their inner

face, their apices rounded.

162 Coleopterological Notices, ITT.

Female.—Broader than the male, less acute behind ; eyes separated by one-

third more than their own width ; antenne one-half as long as the body, the

third joint more than twice as long as the second and two-thirds as long as

the fourth ; anterior tarsi slender, not quite as long as the tibie; fifth ventral

segment broadly impressed, the apex very feebly, narrowly sinuate, the geni-

tal armature truncate at apex, with the angles broadly rounded.

New York; Virginia.

This species is rather abundant and apparently not subject to

great variation.

CISTELA Fab.

Chromatia Lec.—Sm. Misc. Coll., III, p. 244.

This genus is at present quite composite, but the species here

referred to it agree in having the antenne more or less compressed,

always distinctly serrate internally, with the third joint very short

in both sexes, but decidedly longer in the female than in the male,

and the fourth joint of the maxillary palpi somewhat slender, with

the angle at the base less than right.

The genital armature is more or less truncate or feebly sinuate

in the female, as is usually the case throughout the family, and is

deeply bilobed in the male, the two lobes sublaminate and long, but

scarcely attaining the development or densely corneous structure

seen in Capnochroa and Androchirus.

The punctuation and pubescence as a rule are extremely dense,

the latter very short and more or less inconspicuous; the punctures

are, however, much sparser in the aberrant amcna. The latter

species forms the type of the genus Chromatia of LeConte, but the

difference in the form and prominence of the genital armature, “the

sixth ventral segment being prominent and deeply excavated in the

male,’? upon which it was separated, does not of itself appear to be

sufficiently decisive.’ It is quite true that amena differs greatly

from brevis in general facies and sculpture, but marginata is a

satisfactory intermediate in many of its characters in spite of its

much larger size, and it does not seem proper to admit the generic

validity of amena without’ granting that of marginata and also the

Central American nigricornis, a specimen of which is before me,

genus as exemplified by C. brevis and the closely related C. theveneti.
