While the index of the present volume was passing through 
the press, I received, through the kindness of a friend, a copy of 
the first edition of Say’s Entomology, a work of exteeme rarity, 
and which I had never before seen. 

It contains six plates used subsequently in the same work ; 
but as they represent in part species not previously described, 
the work must be cited, and I therefore stbjoin a list of the 
figures. The date on the title page is 1817.

Much to my regret the following error was discovered too late 
for insertion in the corrections on page 790. 

Page 328 line 10, for L. aurrata read L. 6-GurTara. 

A typical specimen of this species in Dr. Melsheimer’s collec- 
tion is the same as Leptostylus interruptus, (Ammiscus interrup- 
tus Hald.) 

A typical specimen of Hlater viridis (vol. 1, p. 890) in Dr. 
Melsheimer’s cabinet, is the Corymbites afterwards described as 
C. micans Germar. The other species of Say, mentioned by me 
as not determined, do not exist in the collections either of Dr. 
Melsheimer or of the late Dr. Harris.

ENTOMOLOGICAL WRITINGS 


OF 


THOMAS Say: 


[From the Journal of the Academy of Natural Sciences, Vol. 1, No. 2; 
June, 1817: pp. 19—23] 


Descriptions of several New Species of North American Insects. 
Order COLEOPTERA. 


Genus CICINDELA Linn. Fab. Xe. 


Antenne inserted into the anterior margin of the eye. Palpi 
filiform, the intermediate and posterior ones nearly equal, penulti- 
mate joint of the latter hairy. Thorax short. Elytra flat, rounded 
at the tip. Clypeus shorter than the labrum. 


1. C. Formosa, American Entomology, Plate VI.* [Plate 
XVIII: ante, 1, 35.] 

2. C. peceMNnoTaTA, American Entomology, Plate VI. [Plate 
XVIII: ante, 1, 34.] [20] 

3. C. DoRSALIS.—Brassy : elytra white ; two curved lines on 
each, suture and curved branch near the base green: lip and tail pale. 

Inhabits New Jersey. 

Head brassy, naked, with green edges. Labrum, mandibles and 
palpi white ; tips of the mandibles and terminal joint of the palpi 
dusky. Thorax brassy, varied with green, margin and back longi- 
tudinally hairy. Scutel green. Elytra white, irregularly pune- 
tured ; suture green, a lunated branch on each elytron terminating 
at the middle of the base; disk with two abbreviated lines, of 
which the anterior is curved outwards and the posterior one in- 
wards, respectively terminating at one of the ends opposite the cen- 


*These reference are to the suppressed first edition of the American En- 
tomology, which I have never seen. The first volume of the second 
edition reprinted in this work was published in 1824.—Lxc.

tre of the other. Body beneath hairy on the sides; hair short, 
prostrate, cinereous; last segment of the abdomen and tail yellow. 
ish. On the sea beach of New Jersey; numerous. 

[Afterwards described by Dejean as C. signata.—Lxc.] 

4. C. nirticoLtis.—Dull brownish-cupreous, beneath green ; 
trunk and head with cinereous hair ; lip white ; [21] outer margin of 
each elytron white with two abbreviated bands, and an interme- 
diate refracted one; trochanters purple. 

Inhabits North America. 

Head coppery, varied with green and blue. Labrum and base 
of the mandibles white. Thorax very hairy, impressed lines blue. 
Elytra punctured irregularly with green, a marginal lunale at base , 
the extremities of which are almost equally prominent; the'band is 
diyaricated on the margin so as to join the anterior lunule, but it is 
interrupted before the terminal lunule, abruptly refracted at the 
centre of the elytron and curved near its termination, towards the 
suture. Body beneath green, very hairy. 

Length rather more than half an inch. 

Common in Pennsylvania, very much resembles C. trifasciata, 
for which itis probable it has generally been mistaken. 

[This description is very indefinite, but the expressions ‘ thorax 
very hairy,’ and ‘ band divaricated on the margin so as to join the 
anterior lunule,’ lead me to refer it to our common sea shore spe- 
cies afterwards described as C. albohirta Dej.; the figure given by 
Say in the Transactions of the American Philosophical Society 
(infra) represents perfectly that species. It does not live within 
the limits of Pennsylvania, though on the banks of rivers beyond 
the Mississippi it is occasionally seen—LEc. ] 


5. C. pustrta.—Above black, obscure ; elytra with two lunules 
and a recurved band, white. Body beneath black-blue, or green- 
ish. Trochanters testaceous. 

Inhabits with the first. [Kansas and Nebraska.] 

Elytra with a marginal Junule at base and another at the tip, 
both very narrow and white ; an intermediate band, divaricate on 
the margin, recurved at the middle of the elytron and terminating 
near the suture behind. Labrum and base of the mandibles 
whitish ; the four basal joints of the antenne purple. 

Length not quite half ofaninch. Found by Mr. Nuttall. The 
band is often obsolete, or only detached portions of it are visible, 
the enlarged marginal part is permanent. [22] 

[ Vol. I. 


OF PHILADELPHIA. 3 


Genus NEMOGNATHA Illiger, Zonztis of Fabr. and Latr. 
Maxillz very much elongated, inflected, filiform. 


N. 1mMAcuLata.—Lemon yellow, immaculate. LElytra with 
scattered punctures. Maxilla not longer than the thorax, and with 


the antennz and palpi black. 

N. rmmacunata, American Entomology, plate III. [Plate 
VII.; ante, 1, 13.] 

Inhabits the plains of the Missouri. 

Antennz black, basal joint pale testaceous. Eyes, maxillze, pal- 
pi, tips of the thighs and tarsi black. LElytra irregularly punc- 
tured, naked, polished. 

Comes near to the description of Zonitis pallida of Fabricius, but 
that insect is said to be large, and may probably be a true Zonitis. 
Our specimens are not more than half the size of NV. vittata. 

Found on thistles (Cardui) by Mr. Nuttall: numerous. 


Genus ZONITIS Fabricius and Latreille. 

Maxillz not elongated. Antennee with the first and the third 
joint of the same length, the second a little shorter, the third and 
following cylindric, the last one fusiform, terminating abruptly in 
a short point. 

Z. BILINEATA.—Ferruginous. Elytra pale yellowish, with a 
black fillet. Scutel black. 

Inhabits with the preceding on thistles. Nuttall. [23] 

Antennz black, the two basal joints ferruginous. Eyes black. 
Elytra naked, punctured, the fillet occupies the middle of each 
elytron and is abbreviated at the base and apex. Scutel black. 
Tibia fuscous. Less than the preceding insect. In its color and 
appearance, except as to size, it resembles NV. vittata. 


Order DIPTERA. 
Genus DIOPSIS Linn. 


Head furnished with two inarticulate, immoveable horns. Eyes 
situated at the extremit es of the horns. Antennz small, placed 
beneath the eyes. 

D. BREVICORNIS—Black, pedicels short, not so long as the in- 
terval between the bases. [Ante vol. 1, p. 116.] 

Inhabits Pennsylvania. 

Head rufous; vertex brown, thorax blackish, a little blended 
1817.]

with cinereous, a lunate impression on each side before, an impres- 
sed band on the middle interrupted on the back ; and an impressed 
angulated one behind. Lateral spines short, black ; posterior ones 
longer, rufous. Wings fasciated with brown near the apex. Feet 
rufous, thighs, and tibia towards the tips, blackish, anterior thighs 
thickened. Poisers white. Abdomen black immaculate. 

Length rather more than three-twentieths of an inch. 

Extremely rare; I found but a single individual in May last 
seated on a leaf of the Skunk Cabbage, (Pothos fetida) near the 
Wissahickon Creek a few miles from this city. This insect will 
be considered as a most interesting addition to the American Fauna. 
(Achias Fab.) 

The insects above described I believe to be new, at least they 
are not noticed in any book to which I have access. 


[From Vol. 1, No. 3: pp. 45—48.] 


Some account of the insect known by the name of Hessian Fly, and ofa 
parasitic insect that feeds on it, 
Read June 24th, 1817. 


Order DIPTERA. 
Genus CECIDOMYIA. 

Genus Tipula of Linné and Degeer. Chironomus of Fabr. Tri- 
chocera of Lamarck. Cecidomyia of Latr. and Meigen. 
Antenne filiform, joints subequal, globular, hairy. Proboscis 

salient. Wings incumbent, horizontal. 

C. prstRUcTOR.—Head and thorax black; wings black, ful- 
vous at base; feet pale, covered with black hair. 

Inhabits the Northern and Middle States. 

Body clothed, with short black hairs; head black; antennz 
shorter than the body, somewhat smaller toward the tip, verti- 
cillate, joints moniliform, separated by a hyaline filament. Tho- 
rax gibbous, black, glabrous, and polished. Scutel prominent, 
color of the thorax rounded behind. Wings ciliate, rounded at 
tip, blackish, the fulvous color of the base is sometimes ex- 
tended upon the nerves of the wing, paler and gradully disap- 
pearing before the middle ; longer than the abdomen. Feet long, 
slender, [46] thighs fulvous at base, furnished at the tip with 

[Vol. I. 


OF PHILADELPHIA. 5 


several very acute claws. Poisers, pale nearly as long as the 
thorax, with a suboval capitulum. Breast sometimes fulvous. 
Abdomen brownish. 

Female.—Antennz longer than the thorax, the joints some- 
what oval, not separated by filaments. Abdomen elongate-oval, 
above rectilinear, beneath somewhat ventricose, fulvous, with a 
dorsal and ventral black vitta widely interrupted by the sutures. 
Tail more or less acute in the dead specimen in proportion as the 
oviduct is exserted. 

Length rather more than three-twentieths of an inch. 

Eggs elongated, linear, pale fulvous. 

Larva.—Body somewhat fusiform, whitish ; tail acute, rather 
abruptly attenuated ; head incurved and attached by the mouth ; 
above hyaline, exhibiting an internal, abbreviated, visceral, green 
line ; beneath with opaque white clouds, which in the young ani- 
mal are perfectly separate and about nine on each side, with an 
intermediate series of smaller ones; as the larva advances to its 
full stature, these unite so as to exhibit the appearance of regular 
transverse segments ; near the anterior extremity are the rudiments 
of feet resembling obsolete tubercules, or crenulz ; when taken from 
the culm it is almost inert, exhibiting very little motion to the eye. 

Length three-twentieths of an inch, breadth one-twentieth. 

Pupa.—Resembles the mature larva, but is of a dark reddish- 
brown color; and appears perfectly inert. 

This well known destroyer of the wheat has received the name 
of “ Hessian Fly,” in consequence of an erroneous supposition, 
that it was imported in some straw with the Hessian troops dur- 
ing the revolutionary war. But the truth is, it is absolutely un- 
known in Europe, and is a species entirely new to the systems— 
being now for the first time described. The insect described by 
Mr. Kirby in the Trans. Lin. Soc. of Lond. vol. iv. p. 232, and 
named by him Zipula Tritici, is without doubt of the same genius 
with this, but specifically distinct. [47] 

The history of the changes of this insect, is probably briefly 
this :—The eggs are deposited by the female in different numbers 
from one to eight, and perhaps more, upon a single plant of 
wheat, and in so doing the parent exhibits another instance of 
that provident care for the welfare of her offspring, which is so 
strongly evinced by many of the insect race. The egg is not 
placed at the axilla of either of the leaves indifferently, but display- 
1817.] 


6 ACADEMY OF NATURAL SCIENCES 


ing some portion of botanical knowledge, the fly carefully insinuates 
her elongated oviduct between the vagina of the inner leaf and 
the culm nearest the root of the plant, where the larva when ex- 
cluded from the egg will be in immediate contact with the culm, 
from which alone its nourishment is derived. In this situation, 
with the body inverted, the head being invariably towards the 
roots, or if above, towards the first joint, the infant larva passes 
the winter. The pressure and puncture of the insect in this 
state of its being, upon the culm, produces a longitudinal groove 
of sometimes sufficient depth to receive almost one-half of the 
side of its body. When several of them are contiguous on the 
same plant, the pressure on the body of the larva is un- 
equal, and an inequality in the form of the body is the conse- 
quence, as well as the destruction of the plant which is subjected 
to their attack. The perfect fly appears early in June, lives but 
a short time, deposits its eggs and dies; the insect from these 
eggs complete the history by preparing for the winter brood. 


Order HYMENOPTERA. 
Genus CERAPHRON Latr. 


Antenne infracted, moniliform, ten or twelve jointed, basal 
joint long, cylindrical. Abdomen subovate. Inferior wings with- 
out apparent nerves. Superior wings with a costal nerve, and a 
single branch, forming an incomplete radial cellule. 

C./ pEsTRUCTOR.—Black, granulated; abdomen glabrous, 
polished ; feet, and base of the antenne, whitish. [ 48] 

In the Larva of Cecidomyia destructor —Head black, opaque, 
sometimes brassy, granulated over its entire surface; eyes not 
prominent, rounded in compliance with the curve of the head, 
and with the stemmata, red-brown; antenne pale brown, fur- 
nished with short cinereous hairs, the two basal joints pale yel- 
lowish ; the terminal ones in the male a little dilated and ap- 
proximated so as to form an obvious ovate-acute mass. Thorax 
with the granule equal to those of the head; black, usually 
brassy before the line of the base of the wings; nerve of the 
wings pale brownish ; feet whitish with black apophysis. Abdo- 
men ovate-acute, perfectly black, highly polished and furnished 
with a few short hairs; the segments of the base are sometimes 
pale yellowish or testaceous. Length one-tenth of an inch. 

[Yor 


OF PHILADELPHIA. 7 


This is often mistaken for the Hessian fly, in consequence of 
being found in wheat fields in vast numbers during the devasta- 
tion committed there by that insect, and many have been deceived 
by the specious circumstance of its evolution from the pupa it- 
self of the destroying larva, under their own observation. But 
the truth is the Ceraphron belongs to that vast tribe of insects 
included by Linné under the Genus Jchneumon. True to the 
manners of its kind the parent deposits her eggs within the 
bodies of the larve of the Cecidomyia destructor, through a 
puncture made by her acute oviduct for the purpose; the 
young, when disclosed from the egg, feeding securely within 
the body of the larva, at length kills it, but not in general until 
after its change into the pupastate. Protected by this indurated 
covering, the parasite undergoes its change, and appears in the 
perfect state, about the latter part of June. It seems probable 
that this insect prevents the total loss of our wheat crops, by re- 
straining the increase of the Cecidomyia within certain bounds. 
The Jchneumon Tipule of Mr. Kirby is congeneric with this, but 
is doubtless specifically distinct.

An account of the ARACHNIDES of the United States. 


The following descriptions of the Arachnides of this country, 
which respire by means of trachez in the manner of insects, may 
be regarded as the continuation of a series of essays, of which the 
“account of the Crustacea,” &c., is the first, on the vast orders of 
articulated animals with articulated feet, (Annulosa of Cuvier) 
natives of this country. As the nature of this journal precludes 
the introduction of old matter or known facts, I shall confine 
myself in its pages, to the description of such of these animals 
only, as appear to be unknown to naturalists, or to the elucidation 
of such, as from their obscurity, are not understood. 


Subclass I. CHPHALOSTOMATA. 
Order Ist, PODOSOMATA. 


Genus *ANAPHIA.+ 
Pl. 5. fig. 7.—a, Trophi. 
Artificial Character—Mandibles longer than the rostrum, 
first joint longer than the second; palpi none; nails single. 
Natural Character —Body very slender, composed of four seg- 
ments bearing feet, and a small suboval caudal process; head 
prominent, not perceptibly contracted behind, and consisting of a 
prolongation of the anterior segment of the body : eyes four, [60] 
inserted on a common tubercle, upon the top of the head : mandi- 
bles robust, didactyle, inserted at the extremity of the head, por- 
rected, parallel, two-jointed, longer than the rostrum, first joint

elongated attaining the tip of the rostrum ; hand abruptly inflect- 
ed upon the tip of the rostrum: rostrum porrected, cylindrical, 
truncated at tip, shorter than the body, and inserted beneath the 
first segment ; palpi none; feet eight, filiform elongated, slender : 
cox three-jointed, the middle one longest: thighs one-jointed ; 
tibie, two-jointed : tarsi two-jointed, the first very short; nails 
single, arcuated, capable of being inflected. 

A. PALLIDA.—Body whitish : ocular tubercle acute at tip; 
eyes sanguineous ; hands suboval, slightly hairy, not dilated, in- 
flected vertically, and with the fingers, hardly more than two-thirds 
the length of the preceding joint ; fingers arcuated, crossing each 
other near the tip; a small, rather acute tubercle at the base of 
the anterior feet (probably the rudiment of the egg-bearing organ ;) 
coxee second joint clavate ; tibie first jomt rather shorter than 
the second. 

Length of the body one fourth of an inch. 

Span of the feet one and one half an inch. 

Inhabits the coast of South Carolina. 

Cabinet of the Academy. 

Of this new genus I found two specimens in the bay of Charles- 
ton, 8. C., upon the branches of the Gorgonia virgulata, and as 
they have not the egg-bearing organs, I suppose them to be males. 
This [61] animal resembles Phowichilus in being destitute of palpi, 
but differs from it in having didactyle mandibles and simple nails. 
In the form of the mandibles it resembles Nymphon and Am- 
mothea but the want of palpi distinguishes it from those genera, 
its proper situation is probably next to the genus Phoxichilus. It 
unquestionably, is generically the same with Phalangium aculea- 
tum of Montague, (Trans. Lin. Soc. vol. 9, tab. 5,) which Dr. 
Leach, in the article Crustaceology of Brewster's Encyclopeedia, 
refers to the genus Nymphon, but which, as far as I can discover, 
he has omitted in his subsequent works. It will of course be a 
second species of this new genus. 


Order JT. POL YMEROSOMATA. 


Family 2. SCORPIONIDEZ.. 
Genus BUTHUS Leach. Scorpio Latr. 
Palpi brachiform, didactyle ; eyes eight; abdomen terminated 
by a caudal process of six articulations, of which the terminal one 
is armed with a venomous aculeus.

OF PHILADELPHIA. 11 


B. virratus.—Fuscous, with three fulvous vitte ; sides 
black. 

Inhabits Georgia and Florida. 

Cabinet of the Academy. 

Body above granulated, granules irregular, distant, three ful- 
vous equal vitta, and an elevated, interrupted vertebral line ; 
sides black, rugose, beneath white ; thorax reddish-brown, more 
seabrous before [62] and behind, hardly marked by the vitta, sube- 
marginate before, and divided by a longitudinal impressed line, 
region of the dorsal eyes blackish ; palpi longer than the body, 
with granulated lines, carpus with three or four of the granules 
more conspicuous ; hand subovate, greatest diameter about equal 
to that of the preceding joint ; fingers filiform, incurved, longer 
than the hand, reddish brown, furnished with numerous minute 
teeth feet paler than the palpi, minutely granulated above and 
beneath ; caudal process color of the palpi, longer than the body, 
with granulated costa, those of the penultimate segment not more 
conspicuous; terminal segment subovate, slightly mucronate 
beneath the aculeus, the costal granule minute. 

Length from tip of the palpi to tip of the caudal process, one 
inch and seven-tenths. 

I found numerous specimens of this species on the sea islands 
of Georgia and in East Florida, hybernating beneath the bark of 
trees. 

The wound inflicted by the puncture of their aculeus, causes 
much pain and intumescence, but is readily cured by the topical 
application of the volatile alkali. 

The species to which vittatus is allied, are the punctatus of 
Degeer and americanus of Linné, but according to Latreille (v. 
Sonnini’s Buffon) these are both spotted with brown, the caudal 
process of punctatus being of the length of the body and that of 
americanus three times the length of the body. [63] It is how- 
ever very possible that our species may be a variety of punctatus. 


Genus CHELIFER Geoff, Leach. 


Palpi brachiform, didactyle ; thorax with the first segment divi- 
ded by a transverse indented iine ; eyes two; mandibles short.

Cabinet of the Academy. 

Body ovate, narrowed before, rounded behind ; thorax black- 
brown opake, gradually narrowed from the base to the tip of the 
mandibles, armed with numerous short, robust spines; feet rufo- 
testaceous ; palpi rufous basal joints subglobular, gibbous behind 
third joint cylindrical, nearly three times longer than the second, 
armed with short rigid hairs, and gradually attenuated to the base, 
fourth joint shorter but somewhat larger than the preceding one, 
and gradually much attenuated to its base; hand black-brown, 
above oblong subovate, laterally linear, fingers as long as the hand 
paler, incurved and furnished with a few elongated, flexible hairs ; 
abdomen above black-brown, and with the feet furnished with 
minute, spine-like hairs, segments margined with obsolete pale 
testaceous. 

Length rather more than one-tenth of an inch. [ 64 j 

Common in decaying wood, under bark, in houses, under stones, 
&e. Ifound a variety on the river St. John, in East Florida, of 
which the anterior portion of the abdomen and posterior part of 
the thorax is rufous. This species considerably resembles C. 
Hermanni of Leach, (Zool. Mise. vol. 3, p. 49.) 


2. ©. oBLoNGus.—Second joint of the anterior feet hardly 
twice as long as the first, rather larger towards the base; thorax 
polished. 

Inhabits North America. 

Cabinet of the Academy. 

Body oblong, sublinear: thorax reddish-brown, polished; tes- 
taceous at base, rather abruptly attenuated from the middle to the 
tip, and with abbreviated flexible hairs, instead of spinules : feet 
pale, testaceous ; palpi reddish-brown, with dilated, short joints, 
and furnished with numerous flexible hairs, second and third 
joints subequal, the latter rather shorter and dilated in the mid- 
dle : hands ovate, almost truncated at base; fingers shorter than 
the hand, and with a few longer hairs ; abdomen above brownish, 
slightly hairy, polished, margins of the incisures testaceous. 
Smaller than the last. 

Occupies the same situations as the preceding. It bears con-

siderable resemblance, in the form of the palpi, to the C. Geoffroyi 
of Leach, (Zool. Misc. p. 50.) This species, as well as the pre- 
ceding, are readily distinguishable from the Phalangium aca- 
roides of Linné, by the mutic antepenultimate segment of the 


palpi. 


Order 3. DUOMEROSOMATA. 


Family 2. PHALANGIDE. 
Genus PHALANGIUM. 


Body rounded; feet elongated ; tarsi with numerous joints;

vitta from the clypeus to the cloaca and lateral fuscous line, above 
with dense, obtuse granules, beneath with distant ones; three 
profoundly impressed lines before the middle, of which the an-

four to six more conspicuous, acute spines: clypeus not elevated, 
concave beneath the obtuse tip; feet, second pair about fifteen 
times as long as the body; tarsi capillary, articulations not con- 
tracted. 

Length, female nearly one-fifth of an inch. Male much smaller. 

The armature of the ocular tubercle is obsolete in the male, 
and in this sex there are generally two whitish [66] lines, drawn 
from the base of the occular tubercle to the tip of the clypeus, 
which are also sometimes visible in the female. 

I have not found these in coitu, but have considered them 


of the same species, from their being associated and somewhat 
similar in form and markings. 


2. P. DoRsATUM.—Whitish with a dorsal fuscous vitta, joints 
of the palpi armed with a series of spines. 

Inhabits the United States. 
1821.]

Family 3. ARANEIDEZ. 


Although I have a considerable number of descriptions of 
Araneides, which I think are new, yet, as I am not sufficiently 
well acquainted with the species of this family, in their different 
ages, prudential motives induce me to refrain from publishing 
them until further investigation shall qualify me for the task. 


Order 4. MONOMEROSOMATA. 
Genus TROMBIDIUM. 


Body consisting of a thorax and head united and distinct from 
the abdomen; two anterior pairs of feet distant from the others ; 
eyes pedunculated, lateral; palpi with a moveable appendice be- 

neath their tips.

I have frequently observed this species, inhabiting, in con- 
siderable numbers, the body of Passalus cornutus. The fore feet 
are, as their slender appearance indicates, used as antenna to feel 
the way, and not as feet to support the body. ‘

rather longer distant hairs, second pair very robust, third joint 
armed beneath with a large, prominent, acute, spine, which js

hind vesicular and whitish, the coriaceous epidermis of the ter- 
gum terminating before the vesicular posterior margin in an emar- 
gination ; feet short and very robust; pulvilli dilated, very short.

lineated; venter plain. 

Inhabits Pennsylvania. 

Cabinet of the Academy. 

Body spheroidal, black, opake, rounded before and carinated

Body spheroidal, somewhat oval, glabrous, polished, black ; 
head longitudinally semi-ovai ; eyes sessile, near the base of the 
head each side, remote; feet hairy, pale testaceous, subequal, 
shorter than the body. 

I found this species several times under stones, &c. It is 
sluggish in its movements, like other species of this genus ; 
when alarmed or in danger the feet are thrown forward together

hairs; palpi four jointed, resembling arms; first joint destitute 
of hairs and longer than the others conjunctly ; second and third 
joints very short; fourth joint longer than the two preceding 
ones, attenuated towards the base and truncated at tip, with 
several short hairs and two terminal setz longer than itself, of 
which the inner one is rather shorter; feet hairy, subequal, pale,

villus and two nails; eyes obsolete or wanting. 


1. I. annuLatus.—Body oval, pale reddish-brown, tinged 
with sanguineous, particularly behind, and with several longi- 
tudinal and oblique, black, abbreviated lines, scattered punc- 
tures, and three abbreviated, longitudinal impressed lines behind ; 
rostrum, with the palpi dilated, rather suddenly contracted at 
base, and annulated more prominently beneath with about two 


elevated lines, which on the sides produce an angulated appear-

lum, the two superior organs emarginate at tip, exterior division 
dentate beneath, inferior organ with numerous resupinate teeth 
resembling fenestrate punctures ; posterior to the origin of the 
palpi above is an orbicular, obscure assemblage of punctures re- 
sembling eyes; black dorsal lines of the male somewhat regular, 
consisting usually of a dorsal line divaricating before, and behind, 
the middle, furnishing a branch each side, which at the tip of 
the abdomen [76] is confluent with a lateral line, which also 
branches off in two or three short lines towards the feet; feet 
with a short robust nail, and a reclivate pedunculated pulvillus 
and nails. 

Found in considerable numbers on a Cervus virginianus, in 
Kast Florida. 

2. I. oRBICULATUS.—Body nearly orbicular, slightly narrower 
before, punctured, ten or twelve longitudinal, abbreviated im- 
pressed line on the posterior margin, marginal impressed line 
none, two longitudinal indented lines before the middle; head 
transverse subquadrate, posterior edge very obtasely rounded, the 
posterior angles complying with the general curve ; palpi oblong, 
sublinear.

Found inhabiting Scturus capistratus of the Southern States. 


3. I. orENATUS.—Body ovate, with distant deeply impressed 
punctures, posterior margin lobated by ten or twelve profoundly 
indented lines, which are abbreviated by an impressed submar- 
ginal line, which becomes gradually obsolete before the lateral 
middle; posterior edge crenulated ; thorax none, distinct; head, 
posterior edge transversely rectilinear, angles slightly arquated 
backward and rounded at tip; palpi oblong, sublinear and regu- 
larly rounded at tip. 

Cabinet of the Academy. 

Found in the Southern States, the color is reddish, [ 77] some- 
times slightly varied with whitish, particularly behind, and the 
lobate divisions of the posterior margin are sometimes whitish 
above, and the disk is obsoletely lineated with black.

pressed line, two abbreviated lines before; head, posterior edge 
transversely rectilinear, angles extended backward abruptly, and 
subacute; rostrum rather short; palpi oval-orbicular. 

Found in the Southern States; the color is reddish or ferru-

dented, abbreviated lines before; head, hind edge rectilinear, 
angles abruptly a little extended backwards, acute; rostrum 
rather short; palpi ovate; color reddish or ferruginous varied 
with white, incisures of the feet white. 

Very much resembles the preceding in form ; the white of the 
back is more or less reticulated, and the [78] feet are white 
above, or only their joints. May not this be J lineatus, if so, 
my name must of course be rejected. 


6. I. puNcruLATUS.—Body oblong-ovate, gradually attenuated 
before, sides hardly arquated, crowded with impressed confluent 
punctures ; thorax destitute of punctures, but with two impressed 
undulated lines; abbreviated lines of the posterior margin not 
deeply impressed, almost obsolete; lateral submarginal line 
deeply impressed, obsolete behind; head, hind edge rectilinear, 
angles abruptly a little projected backward, acute ; rostrum rather

with a few indented points ; beneath, origin of the feet paler red ; 
feet, second and third pair ciliate with very fine and long hairs, 
posterior pair destitute of cilia. 

Length nearly three-twentieths of an inch. 

A common species, inhabiting stagnant pools, &e., in forests, 
and shady places. The posterior feet being destitute of cilie, 
are only useful in walking; when the animal is swimming, they 
are extended behind, without distinct motion. The eggs are 
globular, surrounded by a white gluten, and are deposited on 
almost any object indifferently, from two hundred to three hun- 
dred in number, arranged somewhat symmetrically in parallel,

middle of May. 


Genus LEPTUS Latr. 


Feet six; trophi forming a capitate body; palpi conic, quadri- 
articulate ; an obtuse tube, subconic, advanced ; body soft. 


1. L. arAnEn [ARANE&®].—Body oval, red, with short, dis- 
tant hairs; head whitish, somewhat rounded, [81] contracted, 
at base aid acute at tip; palpi white, a little hairy, rather sur- 
passing the tip of the head; tergum with a deeper red eye on 
each side over the interval between the anterior and second pairs 
of feet, anteriorly indented, and with two lines each of four or 
five indented points. 

Length one-thirtieth of an inch. 

Cabinet of the Academy. 

Of this species, I have found a yee adhering near the base 
of the palpi of an Aranea. 

The head-like process, is sometimes retracted so as to be not 
prominent, but is not long withheld in this position. The body 
is somewhat contractile, not perceptibly as regard its length, but 
in its breadth, by an irregularly undulated motion of the edge. 


2. LL. HIsprIpus.—Body suboval; head with a distinct neck ; 
palpi more robust at base; feet elongated, much longer than the 
body, filiform and furnished with numerous robust, incumbent, 
flexible sete, about twice the diameter of the leg in length. 

My Cabinet. 

1 took no less than ten of these animals from a Phalangium, to 
which they adhered very strongly ; when feeding, they often are 
supported only by the rostrum and palpi, the body and feet being 
elevated so as to be sometimes perpendicular to the supporting 


surface. [82] 
Genus OCYPETE Leach. 


Feet six; mouth rostrated, porrected, with mandibles; palpi 
elongate-conic, with a moveable appendage at base; body soft ; 
eyes two. 


O. comata.—Body subtriangular, very obtusely rounded 
behind, hirsute, and narrowed by an arquated line to the rostrum : 
rostrum short, narrowed and emarginated at tip; posterior feet

the body. 

Inhabits several species of Tipula. 

This is readily distinguishable from the O. rubra Leach, by 
the elongated hairs of the feet. The specimens in my possession, 
are so disposed that the trophi cannot be examined, I therefore 
refer them to this genus by analogy, drawn from habit, &e.

with a submarginal, infracted series of ten or twelve punctures 
furnishing hairs, tip ciliated, reddish, obsoletely dentate. 

Length more than three inches. 

A very large species inhabiting decaying wood, &c.; when ir- 
ritated it diffuses an odor like that of muriatic acid, and is infest- 
ed by Gamasus Juloides. It varies in color; the margin of the 
segments and all beneath are sometimes white, the ultimate seg- 
ment is sometimes almost acutely angled at tip, and there isa 
distinct lateral series of black dots.

gitudinally sublunate ; ultimate segment unarmed, longer than the 
penultimate one, rounded at tip and blackish.

glabrous, an impressed longitudinal line on the vertex ; antennae, 
feet and terminal segment hairy; color, above reddish-brown, 
beneath yellowish white. 

Common in similar situations with the preceding. 

Julus virginiensis of Drury, is also rather common ; it appears to 
be synonymous with J. tridentata of authors. I have found spe- 
cimens double the usual size in the Southern States. It seems 
also to vary in having only the second joint of the feet mucro- 
nate, and in being destitute of the robust ventral spines between 
the feet.

unarmed. 


1. C. HyALINA.—Body much depressed, white, with a double 
blackish internal line; hind feet with third joint five toothed. 

Inhabits Georgia and Hast Florida. 

My Cabinet. 

Head reddish-brown, polished, impunctured, with scattered

joints sessile, cylindric, terminal ones rounded: body white, 
polished, two black internal lines, a few sparse hairs, impune-

Numerous specimens of this species occurred beneath the de- 
caying bark of a live oak (Q. virens) on the River St. John, East 
Florida. The appearance of the posterior feet approximates it 
to Scolopendra ; [112] but the eyes exclude it from that genus, 
as the number of the feet does from Lithobius. 


2. C. SEXSPINOSA.—First joint of the posterior feet two spined.

Body reddish-ferruginous, punctured ; second segment shortest, 
then the fourth and sixth, terminal one indented at tip, and

posterior feet remarkably robust, hardly longer than the ultimate 
segment ; nail very robust, as long as the two preceding joints 
conjunctly. 

A very remarkable species, distinguished at once from al! 
others, by the very thick and short posterior pair of feet, the 
nails of which cross each other, and are much used by the animal 
in its defence.

On a South American species of Estrus which inhabits the human body. 
Read November 26th, 1822. 


Many of the objects of natural history described by Linné are 
at present, entirely unknown, notwithstanding the laborious and 
ardent researches that have been made, by a multitude of ob- 
servers, since the time of the great reformer. This may be in part 
attributed to the great rarity of some of those objects, but it may 
be supposed to be more particularly due to his habitual manner 
of attempting to concentrate all the characters of a being, in the 
comprehensive significancy of a few words. This excessive con- 
ciseness, appears to have been intended to check or discountenance 
a continuation of the habit of voluminous description, so freely 
used by his predecessors; but with due deference to his vast 
and deserved reputation, be it said, that, in the attempt to intro- 
duce a necessary reformation in this respect, that great naturalist 
passed to the opposite extreme. 

In common with the greater number of naturalists of the present 
day, I have very often felt the inconvenience of this imaginary 
improvement and real detriment in zoology, and heartily wish 
that brevity may be sacrificed to accuracy, as I am convinced 
that however desirable every describer may, and, indeed, ought 
to be, to represent the object before him in as few words as possi- 
ble, he should, nevertheless, not hesitate to avail himself of as 
many expletives as will in all probability obviously distinguish 
his object [354] from others, regardless of the number of words 
that may be required for this purpose. 

It is to be regretted that some very distinguished zoologists, 
perceiving as they must this grand impediment to the determina- 
tion of species, still, by their example, perpetuate and in- 
crease this grievance, considering it sufficient for them to add to 


a very laconic description, a reference to a cabinet in which the 
[Vol. II. 


OF PHILADELPHIA. 33 
specimen may be inspected, by the comparatively few persons 
who have the opportunity. 

Now, although a reference to a cabinet specimen ought to be 
considered as the duty of the describer of every animal, plant or 
mineral, whenever such reference is at all possible, yet it never- 
theless seems also indispensable, that a detailed description, in- 
cluding many characters, should at the same time be given for 
the information of the distant naturalist or traveller, in order 
that its utility may not be limited exclusively to our compatriots. 

Amongst a multitude of short and insufficient descriptions, or 
rather indications, we find in Turton’s edition of the Systema 
Nature, the following notice, translated from Gmelin, of the 
existence of a very remarkable insect. 

“‘ (istRUS HOMINIS.—Body entirely brown. Inhabits South 
America. Linné ap. Pall. nord. Beytr. p. 157. Deposits its eggs 
under the skin, on the bellies of the natives; the larva, if it be 
disturbed, penetrates deeper and produces an ulcer which fre- 
quently becomes fatal.” 

This insect, for the identifying of which we have [ 355 | mani- 
festly to depend almost entirely on the habitat, does not appear 
to have been observed by any succeeding writers since it was 
mentioned by its discoverer. Humboldt, however, when occu- 
pied with his highly interesting travels in South America, was 
struck with certain tumors that he sometimes observed to exist 
on the bodies of the natives of that country, and which he attri- 
buted to the concealed operations of the larva of an Gstrus ; but 
as he had no opportunity of verifying this conjecture by satis- 
factory examination, he relied upon the form and appearance of 
the tumors, with a recollection, probably, of the description 
above quoted. 

Clarke, the best writer on this genus of insects, observes that 
the hominis is probably a spurious species, and he further states 
that it “is, perhaps, merely an accidental deposit of G. bovis, in 
the human body, of which there are numerous instances.”’* 

So perfectly satisfied was Fabricius of the non-existence of the 
hominis as a distinct species, that in his Systema Antliatorum he 
has taken no notice whatever of this name and description.

34 ACADEMY OF NATURAL SCIENCES 


The most eminent of living entomologists, Mr. Latreille, ob- 
serves* that neither of the authors who have mentioned this in- 
sect, saw it in its perfect state; he therefore thinks it probable, 
that the larve to which they had reference, were those of the 
Musca carnaria [356] of Linnzeus, or some other analogous spe- 
cies; for, he adds, all the larve of Cstrus known, live on quad- 
rupeds of the order Herbivora and Rodentia. 

Now, although I have not seen the perfect insect, in question, 
yet my object in this paper is to show, by the aid I think of 
sufficient data, that there is an (strus of South America which 
must be added to the catalogue of the foes of our kind, fully 
capable of a notable agency in augmenting the afflictions of 
humanity, and to prove that this species is altogether distinct 
from bovis, to which the ingenious Clark was disposed to refer it. 

A few days since, Dr. Harlan presented to me for examination, 
a small animal preserved in alcohol, that resembled, at first view, 
a parasitic worm, but, on a slight inspection, it became. evident 
that it was no other than the larva of a species of Mstrus ; he 
informed me that he had received it from Dr. Brick, who had 
extracted it from his own leg, during a journey in South 
America. 

Desc. The form of this larva is clavate, the posterior [anterior. 
—Lxc.] moiety of the whole length being dilated and somewhat de- 
pressed ; the segments of this portion are armed with transverse 
series of small, black, horny tubercles, dilated at their bases, near 
their tips rather suddenly diminishing to a filiform curved hook, 
pointing forwards with an acute termination ; these series are six 
in number on the back and sides, placed in pairs, and three in 
number on the abdomen; near the posterior [anterior] termina- 
tion of the body are [857] numerous minute tubercles of the same 
character with the others, excepting that they conform to no regu- 
lar series ; the anterior [posterior—LeEc.] moiety of the body is 
entirely glabrous, cylindrical, or rather elongate conic, of a much 
smaller diameter than the posterior [anterior] portion, and trun- 
cate at the tip; the lipsatthe posterior [anterior] termination of 
the body are short, and the intervening fissure of but little width. 

Total length eleven-twentieths ; greatest width more than three- 
twentieths of an inch.

Obs. From this description we may gather the facts, that the 
larva in question corresponds with that of CM. bovis in being 
destitute of hooks or holders at the mouth, but it widely differs in 
general form, as the larva of bovis is oblong-oval, hardly more 
narrowed at one end than at the other. The appearance of the 
series of minute hooks which subserve the functions of feet, in 
the latter species; also are very different from that of the cor- 
responding armature of this larva, the superior line of each 
double series being narrow, and seemingly composed of but a 
row of hooks, whilst the inferior line is much more dilated, and 
the hooks far more numerous than in the superior line ; indeed, the 
series of hooks of the South American larva are more like those 
of the larve of @. equi and hemorrhoidalis, than those of the im- 
perfect bovis or ovis. But independently of those considerations, 
the single character of the much attenuated form of the anterior 
[posterior] part of the body of this larva, at once and eminently 
distinguishes it from any [ 358] other yet known in this family ; 
while at the same time, the above description, taken in conjunc- 
tion with its habitat, forbids the supposition of its belonging to 
any other group, and will, I think, justify the restoration to its 
place in the system of the Linnean. @strus hominis. To which 
of Latreille’s recently established genera it belongs, is at present 
impossible to determine, though, for the present, it may, perhaps, 
be not unsafe to refer it to the Cute[re]bra* of Clark. | 

Since the above was read to the Academy, Dr. Harlan has 
furnished me with the following interesting extract of a letter, 
which he received from a gentleman from whose leg this larva 
was extracted :— 

“After avery sultry day’s march, and being very much fa- 
tigued, I went to bathe in the Chama, a small stream emptying 
in the lagoon of Maracaibo. Not long after coming out of the 
water, I received a sting from some insect, in the left leg, over 
the upper and fore part of the tibia; it was several days attended 
with a considerable degree of itching, but without any pain, and 
I continued on my journey some few days longer without ex- 
periencing much inconvenience; except during several periods of

36 ACADEMY OF NATURAL SCIENCES 


perhaps two or three minutes continuance, when an acute pain 
came on suddenly, and was severe whilst it continued, and then 
as suddenly subsided. On my arrival, and during my continu- 
ance at Il. Rosaria de Cucuta, I walked [359] with difficulty ; 
there was a considerable tumefaction over the tibia, which had 
the appearance of ordinary bile (phlegmon ;) in the centre there 
was a small black speck; the usual applications were used with- 
out any success, and the tumor became more irritated and in- 
flamed, and thus it remained for some days, attended at times 
with a most acute pain, which for a few minutes was almost in- 
tolerable. 

“Tn returning to Maracaibo, I had to descend the Cottatumba 
in an open boat, without any shelter, and being wet to the skin 
by the cold rains which fell every night, [ suffered much, and 
was almost constantly tormented by the tumor, which became 
more painful at those particular periods than usual; during this 
passage, which lasted for twelve days, I was induced to scarify 
it, and had recourse to the usual topical applications, but without 
success. At times I imagined that I felt something moving, and 
suspected that there was something alive beneath the skin. 

“After my return to Maracaibo I became scarcely able to walk, 
and was, in a manner, confined to my quarters. In this situation 
I continued two weeks longer, the tumor haying began to dis- 
charge, and without any diminution of the painful periods. 

“ Being now nearly worried out, it occurred to me to try a 
poultice of tobacco, which was used for several nights, having 
previously scarified the tumor; during the day I frequently 
dusted it with ashes of segars: as an ingredient I used rum in- 
stead of water [360] in making the poultice. On the fourth 
morning after this remedy, I felt considerable relief, and on the 
fifth, with a forceps, I drew out the worm which you have now 
in your possession, and which was then dead. 

“Tn a few days the sore assumed a healthy look, and in ten 
days was perfectly healed up, although, at times, I yet experience 
a heavy pain in the part from whence the worm has been taken. 
It had travelled on the periosteum along the the tibia for at least 
two inches. The severe pain which I experienced from those 
periods, I attribute to the irritation of some of the branches of 
the nerves distributed to the parts by the worm in its progress.

Respecting this worm there are different opinions among the 
Spaniards and Creoles. Ouche is the name it is called by some, 
who say it is produced by a worm which crawls on the body, from 
the ground, and penetrating the skin, increases in size. Others 
maintain that they are produced from the sting of a winged insect 
which they call Zancudo,* others again, call the insect Husano; 
for my part, I am rather inclined to think that they are produced 
from the sting of a winged insect, which deposits its egg. 

“N. B. Should it even be proved that the form of the anterior 
part of this larva is owing to the violence used in extracting it, 
of which there is no appearance, still it will stand as distinct 
from other known species.” 

[The larva above described, is now supposed to be that of Cute- 
rebra noxialis Goudot, for the characters of which see Annales de 
la Société Entomologique de France, 2d series, 2, xli. For a de- 
tailed discussion of all the facts known on the subject of Gstri 
in the human body, consult Keferstein, tiber Gstrus hominis 
Verh. Zool. Botan. Vereins in Wien, 1856, 637. 

While travelling in Honduras, several of my companions were 
very much afflicted with similar larvae; they seem to infest par- 
ticular portions of the body not usually exposed; the pectoral, 
dorgal and lumbar regions, the thighs and upper parts of the 
arm. When the eggs were deposited, was entirely unknown to 
the patients, none of them having ever observed a fly alight on 
the body; but from the position of the parasite, it is most proba- 
ble that the eggs were laid while the patients were bathing. 
The effects of these intruders are very much exaggerated in the 
text ; they produce a swelling, having the appearance of an ordi- 
nary boil, in which, at times, is felt, for a few seconds, an acute 
pain when the worm moves; the method of extraction is very 
simple, and but moderately painful. The tumor is held be- 
tween the thumb and forefinger, a lighted segar is approached 
to the skin as near as the patient will permit, when the worm 
becomes restless, and the point of his body will be seen at a very 
minute orifice in the skin, not before obvious; the segar is im- 
mediately dropped, and with both hands the tumor is com- 
pressed violently; the worm is thus forced out, sometimes with 


*The word Zancudo is used by the South American Spaniards to de- 
note several species of Culex.—3s.

such velocity as to be projected several inches. No inflamma- 
tion or discharge follows, but the sac immediately closes and heals. 
Sometimes the worm is so small as to resist this mode of ex- 
traction ; a piece of tobacco leaf is then gummed over the tumor, 
(usually with an exudation from the skin of a plantain;) the 
worm dies in a few hours, and is then readily removed by 
squeezing the part. I have nothing to add to the description of 
the larva in the text, as emended by me, except to say that my 
specimens were regularly clavate, not at all depressed; the form 
mentioned above was perhaps owing to contraction, produced by 
the liquor in which the specimen was preserved. The figures 
given by Mr. Goudot are regularly oval, and not at all clavate. 
The name Gusano del Monte is commonly applied to the worms 
by the natives, while the insect is called Zancudo gusano; the 
word Zancudo means simply long legged, and it is difficult to 
understand how it could be applied to a species of Cuterebra. 
The natives assured me that the fly was frequently seen, that 
it was of a grey color, and resembled an ordinary mosquito, ex- 
cept in being larger. I imagine that some species of Tipula 
was meant. A similar superstition in the United States has con- 
ferred upon those harmless insects the fearful title of Gallinip- 
pers.—LEC. ]

Descriptions of Dipterous Insects of the United States. 
Read Dec. 24th, 1822, 

The dipterous insects, from which the following descriptions 
are drawn out, were chiefly collected by myself, during the late 
expedition to the Rocky Mountains under the command of Major 
Long, and patronage of Mr. Calhoun, the present Secretary of 
War. 

Of these insects, many appear to be common inhabitants of 
the United States, throughout the immense region included by 
the Rocky Mountains and the Atlantic ocean, between the parallels 
of latitude 35° and 41° north; others are probably restricted to 
the Western States, and some were seen only in the vicinity of 
the Missouri river; along the base of the great northern Andes, 
where numbers of new and highly interesting animals and plants 


[Vol. TI. 


OF PHILADELPHIA. 39 


were for the first time detected by the party, interesting animals 
of the order under consideration were also collected. The speci- 
mens are in my cabinet. 


CULEX Linn. 


1. C. PUNCTIPENNIS.—Body dark rufous, covered with cinereo- 
ferruginous hair; feet elongated ; wings maculated. 

Inhabits the United States. 

Orbits, bright cinereous; eyes deep black; antennz and pro- 
boscis deep fuscous or blackish immaculate ; thorax dark rufous, 
with obsolete blackish lines, and covered with cinereo-ferrugin- 
ous hair; wings hairy, dusky, with a hardly perceptible pale 
band beyond the middle, and obsolete dusky spots; scutel gla- 
brous, dark rufous, with a longitudinal bluish vitta; halteres 
yellow at base; feet elongated, deep fuscous or blackish; pectus 
each side above the posterior feet plumbeous. 

It is probable this is the species which Fabr. considers as the 
same with the pulicaris of Europe; it is common on the Missis- 
sippi, and troublesome to travellers. When the insect is at rest, 
the wings being incumbent, one on the other, the pale band is 
very distinct; when recent, the eyes are greenish-blue. I ob- 
served this species in considerable numbers on the Eastern shore 
of Maryland. The dusky spots on the wings of this species, are 
occasioned by the thicker growth of hair in those parts. 

[Belongs to Anopheles: Wiedemann has changed the name to 
A. crucians.—SACKEN. | 


2. C. 5-rasctaTus.—Body clothed with cinereous hair ; abdo- 
men annulate with blackish. 

Inhabits the Western States. 

Eyes deep black; antenne: fuscous, region of the base paler ; 
proboscis black ; thorax with a dilated dorsal fuscous vitta ; pectus 
each side varied with blackish ; halteres entirely whitish ; scutel 
glabrous; wings with dusky nervures, immaculate; feet mode- 
rate, fuscous ; thighs whitish ; abdomen cinereous; tergum with 
five black, broad fascie ; tail black above. [11] 

Length about one-fifth of an inch; proboscis one-tenth of an 
inch. 

This is an exceedingly numerous and troublesome species 
We found them in great numbers on the Mississippi in May and

June. The hairy covering is very deciduous, and when an in- 
dividual is caught by hand, the back of the thorax, in conse- 
quence of being denuded by the touch, exhibits the dorsal vitte 
of a blackish color confluent at the base, with an oval black spot 
on each side. The abdominal annuli are sometimes fuscous or 
even light brown. 

Legs much shorter than those of the preceding species, but 
like them in not being annulated. 

[Also an Anopheles: Wiedemann has named it A. ferrugi- 
nosus.—SACKEN. | 


2. C. pAMNOSUS.—Rostrum and tarsi annulate with white. 

Inhabits Pennsylvania. 

Head above with rather long yellow-ferruginous hair ; antennee 
pale-brownish ; rostrum blackish; with a broad white band on 
the middle ; thorax black, with three cinereous lines, and clothed 
with yellow-ferruginous short hair ; scutel dull testaceous ; pleura 
grayish ; feet pale, covered with blackish hairs; joints of the 
tarsi, excepting the first, whitish at their bases ; tergum brown, 
basal margins of the segments cinereous-whitish. 

Length a quarter of an inch. 

This is one of the most common and troublesome of our mos- 
quitoes. It seems to correspond in some degree with the cingu- 
latus Fabr., although we must infer from his description, that 
the posterior tarsi [12] only are annulated. Wiedemann con- 
siders the cingulatus as the male of his molestus, of which all the 
tarsi are annulated, like those of our species. I feel, however, 
perfect confidence in the description of Wiedemann, and there- 
fore must consider our species distinct, inasmuch as the thorax is 
not “ lateribusque niveis ;’ and from the laudable accuracy of 
that author, I cannot suppose that he would have overlooked 
the annulation of the proboscis, which certainly exists in this 
species. 

[Wiedemann has changed the name to C. teniorhynchus.— 
SACKEN. | 

4, C. TRISERIATUS.—Anterior margin of the wings fuscous ; 
tergum with white spots on each side. 

Inhabits Pennsylvania.

with dusky hair; thighs naked, blackish above near the tip ; 
tergum with a triangular white spot at the base of each segment

This is one of the species which are called prairie flies ; it is 
numerous in the prairies of the State of Missouri, and is very 
troublesome to the cattle. I have seen cattle in the forests 
which margin the prairies, when attacked by these insects, start 
suddenly and plunge into the thickets, that the branches may 
divest them of their enemies. Travellers are much incommoded 
by them; many cover their horses with canvas, Xc., to shield 
them from their attacks, or rest in some shaded or secluded situ- 
ation, during that part of the day when they are most abundant.

poisers pale ; capitulum black beneath, and near the tip above ; 
feet pale, tarsi and anterior thighs dusky: tergum with silvery 
hairs each side at base, and each side near the tip. 

Length three-tenths of an inch. 

Very closely allied to A. morio Fab. I observed this species 
in considerable numbers near Merrimac river, Missouri. The 
terminal joint of the antenne is rather short, by which character 
it may be distinguished from A. fulvohirta Wied. It is referable 
to the fifth tribe of the genus Anthrax, agreeably to Wiedmann’s 
divisions. 


2. A. LATERALIS.—Black ; wings hyaline ; sides with fulvous 
hair ; tergum banded. 

Inhabits Pennsylvania and Maryland. [43 ]

hypostoma, a black spot on each frontal orbit, and vertex black ; 
thorax dusky, or blackish, with three black vittee, sides before 
the wings dull cinereous, bounded beneath by another black line, 
beneath the posterior angles is a fascicle of gray hairs, above 
which are a few ferruginous hairs; scutel reddish-brown, with 
short black hair, and a small white spot at the subangulated tip ; 
pleura and pectus reddish-brown; feet reddish-brown, tarsi 
blackish ; wings, costal areola with a small hyaline spot, which is 
the termination of a band extending in a slightly arquated di-

rection to the inner angle of the wing, and interrupted by the 
nervures into five compartments; the three larger [44] cellules 
of the hinder margin, with the exception of the margins of the 
nervures, hyaline ; a hyaline rounded spot occupying the exterior 
half of the central cellule, with a smaller spot on each side of 
it ; sometimes obsolete or double; above this central cellule, and 
near the costal nervures, are two double distant small hyaline 
spots; tip of the wing hyaline, the two nervures margined with 
blackish, the margin of the superior one is generally interrupted 
in the middle; tergum reddish-brown, covered with black hair, 
first segment with cinereous hair each side of the scutel; second 
and third segments with each four small white spots on the pos- 
terior edge, the lateral ones on the former linear ; fourth with but 
two, the lateral being obsolete; fifth with a transverse line each 
side, sometimes crossed by a longitudinal line extending on the 
posterior segments, and exhibiting a cruciform mark, these marks 
and dots have a silvery brilliancy. 

Length seven-tenths of an inch. 

This species seems to come nearest to Meigen’s second tribe, 
but it differs by having an additional cellule under the large 
central cellule of the wing. I labelled it in my cabinet with the 
Fabrician name of capucina, but I cannot identify it with the 
somewhat detailed description which Meigen quotes from Fabri_ 
cius, nor yet with Pallas’s description of the caloptera, that both 
Meigen and Wiedemann quote, and regard as synonymous with 
the capucina, which they believe to be a native of Europe. [45] 

That our insect is totally different from the caloptera no one 
will fora moment doubt, for the latter is no larger than the 
morio, whereas our insect is nearly equal to the cerberus in size. 

In deference therefore to the opinion of the authorities above 
referred, I describe this species as distinct, though it seems pro- 
bable that Fabricius had this species in view when he referred to 
North America as the native country of the capucina.

lineolar bands; venter cinereous ; segments, particularly the third, 
black at base. 

Length of body more than eleven-twentieths of an inch. 

Found in Pennsylvania, and also in Missouri. It belongs to

Var. a. Feet pale. 

I have a specimen in which the external branch of the termi- 
minal furcate nervure is continued a short distance beyond its 
connexion, as in Meigen’s fig. 23. The antennz of this species 
are like those of Dioctria 8-punctata, excepting that they are 
acute at tip, and the arrangement of the nervures, decides the ge- 
neric affinity of this insect. ,

3. LAPHRIA MACROCERA.—First joint of the antenne elonga- 
ted; body black. 

Inhabits Pennsylvania. 

Body somewhat polished, with short, prostrate, grayish hair, 
punctured ; antenna, first joint more than four times as long as 
the second ; wings a little dusky, nervures nearly as in the prece- 
ding species: poisers pale-yellowish ; feet black, tibia and base of 
the tarsi pale testaceous ; tergum on each side and at tip margined 
with testaceous. 

Length one-quarter of an inch. 

This insect closely resembles the preceding species, [74] but 
the elongated first joint ofthe antennz, the want of white poste- 
rior edges to the abdominal segments, together with the color of 
the lateral margin and tip of the abdomen, prove it distinct. I 
had formerly placed both this insect and the preceding under the 
genus Dioctria, but the disposition of their wing neryures is pre- 
cisely as in L. ephippium.

pale yellowish hair, which, on the anterior part, and on the lat- 
eral edge is tinged with ferruginous; pleura blackish-piceous, with 
two fascicles of ferruginous hair; wing nervures brown, margined ; 
scutel blackish, ciliated with dusky hair; feet blued-black, two 
anterior pairs of tibia with yellowish hair, posterior thighs cla- 
yate, anterior pair of coxze concealed by yellowish hair; tergum 
blackish, the three intermediate segments with dense pale yel- 
lowish hair, which is interrupted in the middle, and does not oc-

LEPTOGASTER Meig. 


L. ANNULATUS.—Feet whitish, annulate with rufous. 

Inhabits Pennsylvania. 

Antennee and trophi whitish ; thorax pale cinereous, with three 
dilated pale brown lines; wings hyaline, immaculate ; anterior

elongated, dilated at tip, segments yellow-brown, dark reddish- 
brown at base and on the terminal submargin, terminal margins 
white. 

Length two-fifths of an inch nearly. 

The neryures of the wings of this insect, do not perfectly cor- 
respond with those of L. tipuloides, which circumstance, com- 
bined with another highly important difference that this insect 
exhibits, in having but two nails to the tarsi, would justify the 
generic separation of the annulatus from the tipuloides, and its 
reference to a distinct genus. 

It is not a Phthiria of Wiedemann ?

terior spine of the anterior tibia much larger than the interior 
one. 

Length three-tenths of an inch. 

This is a very common insect. The wings have a white ap- 
pearance, and are strongly contrasted with the color of the 
body, and the brown and definite stigma. The posterior tibia of 
the male are much more dilated towards the tip than those of 
the female.

the disk, that in other species connects the inner branches of the 
two bifurcated nervures together, is entirely wanting. 

Length one-fifth of an inch. 

[Wiedemann who had specimens communicated by Say before 
him, describes this species as Dilophus orbatus Say. I coilected 
a Dilophus in Florida which agrees very well with both descrip- 
tions. The absence of the central cross nervure is not a constant 
character ; although it is not seen in many specimens, some show 
the cross neryure distinctly, others have it very faint, and others 
again show a beginning of it. This cross nervyure, when ap- 
parent, is situated about half way between the upper cross ner- 
vure and the fork. Wiedemann describes the female ; the sex is 
not mentioned by Say, but he evidently refers to the same sex. 
As I have several males in my possession, and they differ con- 
siderably from the female, I take occasion to give the descrip- 
tion. 

D. orpatus. $—Black, shining: feet black, with black hairs- 
Wings pale yellowish, tinged with pale brownish along the ante- 
rior border ; stigma fuscous ; nervures near the anterior border 
brown; the others very pale; central cross nervure sometimes 
wanting, sometimes distinct, and then situated as in the female. 

The color of the hairs on the feet, and the position of the 
cross nervure distinguish the male of this species from the male 
of another American Délophus, (D. serraticollis Walker 7), which 
is, besides, a little smaller. The females of the two species are 
entirely different, and cannot be easily mistaken.—SACKEN. ]

SARGUS Latr. Meig. 


S. vir1pIs.—Body green, polished ; wings dusky ; eyes above 
brassy. 

Inhabits the United States. 

Body green, polished, varied with brassy, and in a certain

brown, when recent deep green, polished beneath, above tinged 
with brassy, sub-opaque, [88] and separated from the green of 
the inferior portion, by a red line; antennz black; labia pale; 
tibia blackish.

Var. a. Bluish-purple. 

Var. b. Bluish-purple ; abdomen green. 

A very pretty species; I found it near Cincinnati, perched 
upon a leaf; it is also an inhabitant of the Atlantic States. It 
has a bright-green appearance, although covered with very short 
hairs, but these are hardly discernible to the unassisted eye. It is 
closely allied to S. wanthopterus Fab., but the joints of its feet 
are not yellowish, as those of that species are.

and the markings of the tergum are different. 


3 8. concavA.—Thorax bluish-green, tergum with four yel- 
low bands. 

Inhabits Pennsylvania. 

Head whitish, sericeous ; antenne pale testaceous; margin of

Very much resembles S. ribesi? of authors, but the second and 
third bands of the tergum are widely concave behind, instead 
of being almost acutely notched, as in the common European 
species. I obtained several pupe of this insect, adhering by the

inferior part of the abdomen to the rails of a fence. This in- 
cluded insect was evolved on the 22d of April. 


4. §. quapRATA.—Thorax bluish-bronzed ; abdomen with 
eight very large quadrate yellowish spots. 

Inhabits the United States. 

Head bluish-bronze, with short cinereous hair; frontal eleva- 
tion dusky; antenne dark reddish-brown; thorax and scutel 
bluish-bronze, polished, immaculate; feet testaceous; anterior 
tibia and tarsi of the male dilated, the joints of the latter much 
shortened ; first and last joints of the posterior tarsi blackish ; 
tergum with eight very large, quadrate, fulvous spots, occupy-

sures black, the two spots of the penultimate segments are hardly 
separated, sometimes united into a continuous band, and the ul- 
timate or anal segment is immaculate, somewhat livid; venter 
yellow, whitish at base.

(which joins the tip of the preceding segment to form a narrow 
band,) band on the middle not attaining the lateral edges, and 
most profoundly emarginate behind, and posterior edge yellow ; 
fifth segment with a triangular basal spot each side, and tip, 
yellow. 

Length to the tip of the wings half an inch.

It requires some examination to perceive the difference be- 
tween this insect and the S. corolle of Fabr., but on inspecting 
the third and fourth segments of the tergum, it will be observed, 
that there are at least two more bands on our species; these bands 
are narrow and are formed by the confluence of the yellow and 
posterior edges of those segments with the yellow basal angles of 
the succeeding segments. 

It is highly probable that the band on the middle [92] of the 
fourth segment, and perhaps also that on the third are sometimes 
entirely separated by their posterior emargination, each into two 
oval spots. 

6. S. MARGINATA.—Thorax blackish, with a yellow margin ; 
tergum spotted, banded and edged with yellow. 

Inhabits the United States. 

Head yellow, a blackish line above the antenee ; thorax black- 
ish, tinged with olivaceous or glaucous, a lateral yellow line con- 
tinued to the scutel and an obsolete dorsal cinereous one ; scutel 
yellow; feet pale, posterior tarsi a little dusky at tip; tergum 
blackish, edged with yellow; first segment with a yellow basal 
edge ; second segment with a yellow band on the middle; third 
and fourth segments each with a dorsal line and somewhat ob- 
lique spot each side confluent with the base yellow, sometimes 
tinged with rufous ; fifth segment with two oblique yellow spots 
confluent at tip. 

Length rather more than one-fifth of an inch. 

This insect is smaller ‘than the preceding ones, and may be 
readily distinguished from them by the yellow abdominal edge, 
as well as by the different arrangement of its spots. It is sub- 
ject to vary in the character of its tergum, in having the spots 
sometimes almost confluent with each other, or in being colored 
with rufous. 

7. S. Gemrnata.—Thorax with a yellow margin; tergum 
spotted and banded with yellow. 

Inhabits the United States. 

Head yellow silvery, at its junction with the thorax [93] 
glaucous ; antenne yellow; thorax bronze-blackish, a yellow line 
each side, and an obsolete cinereous dorsal one ; scutel color of 
the thorax, with a yellow margin: feet pale, posterior pair with

the thighs and tibia arquated, the former blackish at tip, the 
latter sub-bifasciate with brown; tergum black; first segments 
yellow on the basal edge ; second segment with a yellow band on 
the middle ; third and fourth segments with each a central longi- 
tudinal line, and two triangular spots on each side ; fifth segment 
four spotted. 

Length about one-fifth of an inch. 

About equal in size to S. marginata 8., from which it may be 
known by its double lateral spots of the tergum, as well as by 
the absence of a yellow edging upon this part of the body.

ous ; feet whitish, dusky at base ; tergum black, with three lunules 
on each side, and the two terminal segments edged with yellow; 
venter yellowish, exterior edge and disks of the segments black. 

Length to the tip of the wings three-fifths of an inch. 

Size of S. transfuga Fabr., which it very closely [ 94] resem- 
bles, and is to be distinguished by the somewhat darker coloring. 
Ts it not a variety of that species? 


RHINGIA Fab. 

R. nastcaA. $.—Tergum yellow, incisures and dorsal line 
black.

side of the disk, and extends to the lateral edge of each of the 
three basal segments. 

Size of S. rostrata Fab., to which it is very closely allied, but 
it has a larger portion of black upon the tergum, the incisural 
lines and the dorsal line being wider, and of a much more in- 
tense color; the fourth segment also is much darker than in that 
insect. Ihave a female still more like the rostrata; the color 
and markings of the head, thorax and scutel being similar, and 
the fourth segment of the tergum is much tinged with yellow, 
but still the above remark respecting the intensity of the color 
of the sutures and dorsal lines apply to this specimen. [ 95]

Length’ of the body three-tenths, of the posterior feet less than 
three-fifths of an inch. 

The anterior pair of feet, when compared with the others, are 
very short, and being extended before the head, considerably ele- 
vated above the plane on which the insect moves, and also being 
constantly vibrated, they assume the appearance of antennee. The 
whiteness of the anterior tarsi is very distinct and characteristic. 

This species occurred in the State of Illinois, it is also found 
in Philadelphia.

A remarkably splendid insect, and is a large species. It occurs 
in the country bordering the Platte and Arkansa rivers near the 
mountains. [143 ] 

5. C. oBsoLeTA.—Black ; labrum and point on the elytra

polished : antennz four basal joints dark purplish: labrum and 
exterior base of the mandibles white : thorax with two transverse 
indented lines connected by a longitudinal one; lateral margin 
with cinereous hair: elytra with minute profound punctures to- 
wards the base, impunctured towards the tip; a transverse white 
abbreviated line on the middle of the submargin, and an obsolete 
apical dusky-yellowish dot: venter tinged with purplish. 

Length four-fifths of an inch. 

Var. a. Black, immaculate. 

This large and fine species we observed to be not uncommon 
on the banks of the Arkansa river, near the mountains. It 
seems to be closely related to C. tristis Fab. The elytra exhibit 
in some lights a silky appearance.

92 ACADEMY OF NATURAL SCIENCES 


Body pale testaceous, with numerous minute hairs, which on 
the elytra are yellowish: head with a slight irregular frontal im- 
pressed line each side: antenne brown at tip: thorax witha 
longitudinal impressed line from the head to the scutel: elytra 
black-blue, [144] with very obtuse hardly impressed grooves : 
venter testaceous or blackish-piceous. 

This species was found by Mr. Nuttall in Missouri, and I have 
since observed great numbers of them near Engineer Canton- 
ment. These chiefly occurred during the winter, in a quarry 
from which building stone had been taken for the use of Camp 
Missouri. They were found hybernating in the fissures of the 
rocks. 

It differs from the 6. fumans in being much inferior in point 
of size, in this respect approaching nearer to B. crepitans of 
Europe. The greatest width of the thorax is much more con- 
siderable in proportion to the shortest diameter, than that of the 
Jumans, and of course the thorax appears proportionally wider 
before. The color, also, of the head and thorax is different, and 
the elytra are far more slightly grooved. It possesses the singu- 
lar power of crepitating common to its congeners. 


FERONIA ILatr. 


1. F. surercriiosA.—Apterous; black, impunctured ; elytra 
tinged with purplish ; basal thoracic lines dilated. 

Length nearly two-thirds of an inch. 

Body black, impunctured, glabrous: antennee surpassing the 
base of the thorax, with brownish hair towards the tip; frontal 
groove much dilated: labrum and palpi piceous, the former 
emarginate ; thorax wide before, much marrowed behind ; dorsal 
[ 145 ] line distinct, basal lines dilated; a very distinct anterior 
transverse line; lateral edge rectilinear from near the middle to 
the posterior angles ; posterior angles rounded ; base wider than 
the petiole: elytra tinged with purple ; striz profound, impune- 
tured ; interstitial lines convex : beneath tinged with piceous. 

This species, which seems to belong to the genus Pterostichus 
of Bonelli, is closely allied to that which I have described under 
the name of stygicus, but the thorax is differently formed, being 
much wider before, the antennz longer, frontal grooves more 
dilated, the elytra of a different color and more obtuse.

Length more than two-fifths of an inch. 

Body black, glabrous : vertex with two obsolete piceous spots, 
placed near the eyes, and very distinct in a particular exposure 
to the light: antennze piceous, the joints paler at their bases, to- 
wards the tip with light brownish hair: palpi, tip of the mandi- 
bles and of the labrum piceous, the former tipped with pale yel- 
lowish: thorax narrower than the elytra, longitudinally suborbi- 
cular ; lateral edge a little recurved, particularly at the hind 
angles, which are not excurved, but obtusely rounded; dorsal 
line and anterior transverse line impressed, basal lines almost 
obsolete in the concavity of the lateral base, which is not rugose : 
elytra with a very slight cupreous reflection ; striae acute, im- 
punctured, interstitial lines flat : all beneath piceous. 

This insect was found in the Arkansa Territory by Mr. Thomas 
Nuttall. It is so closely allied to the species which I have named 
placida, as not to be, at first sight, distinguished from it ; never- 
theless, on comparing it with that species, it will be discovered

This species is very similar to the preceding, and differs in 
having a rufous postpectus and venter, and immaculate front. 
It also resembles Clerus dubius Fab., but differs from it, if I am 
not mistaken in that species, by being much smaller; and besides 
other differences, by the central band of the elytra curving back- 
ward, and not towards the head, as in dubcus. [192]

quadrate black spot behind the scutel. 

It occurs on the Missouri, and is a fine insect, probably one 
of the largest of the genus. In the colors and form of body it 
most strikingly resembles H. fasciata Fabr., but it is much larger, 
and there is not the slightest oppearance of punctures on the 
elytra ;. the humeral black spot is angular, and its anterior angle 
is extended towards the humeral angle ; the basal portion of the

completely to inclose the transverse black spot. In the /asciatu 
the elytra are distinctly punctured in striz, the humeral spot is 
orbicular, and the basal portion of the basal band does not extend 
towards the scutel further than the middle of the base. In the

Hydrophilus ater 2 Melsh. Catal. 

Body elongate-oval, black, tinged with olivaceous: head with 
two diverging frontal series of impressed punctures; punctures 
before the eyes and on the orbits: antenne, palpi and suture of 
the clypeus yellowish: thorax with a few punctures each side, 
and an abbreviated oblique series of punctures each side before 
the middle: elytra, each with four series of punctures, the ex- 
terior one double: beneath black: pectus with very short dense 
yellowish hair before ; a bifid prominence for the reception of the 
anterior tip of the sternum: postpectus covered by short dense 
yellowish hair: sternum grooved before, rounded at the anterior 
tip, and elongated, subulate, perfectly rectilinear behind : abdo- 
men glabrous, with a triangular marginal spot of short yellowish 
hair on each segment. 

Length from one and one-fifth to one and two-fifths of an inch. 

I think this a different species from the H. ater of Oliv., inas- 
much as no notice is taken, in the description of that insect, of 
lateral ventral triangles which are so conspicuous in our speci- 
mens. It is also a more elongated insect than Olivier’s figure 
represents the ater to be; in this respect approaching [201] much 
nearer to his figure of ob/ongus, which, however, is said to have 
ferruginous thighs, and a but slightly canaliculated sternum. 

In a certain light, the elytra appear, under a lens, to be marked 
by seven or eight capillary reddish lines. It is rather rare in 
Pennsylvania, but I obtained several specimens near the Rocky 
Mountains.

much abbreviated line of impressed punctures each side before the 
middle, and a few lateral punctures: elytra very obtusely rounded

flattened, with an impressed line; posterior tip rounded and hard- 
ly extending beyond the base of the postpectus : feet dark piceous. 

Length from three-fifths to thirteen-twentieths of an inch. 

This species, which is found equally in Pennsylvania and on 
the Missouri, is certainly very closely allied to the H. caraboides 
of Fabr. The venter as [2062] well as the postpectus of this 
species has a silky appearance in a certain light, occasioned by its 
minute dense hairs. The posterior termination of the body is 
more obtusely rounded than the head.

States; itis not unfrequent on the Upper Missouri and on the 
Arkansa. 

It is closely allied to Copris lunaris and emarginatus, but may 
be distinguished from either by the punctured interstitial spaces 
ef the elytra. It seems also related to C. Ammon, but Olivier 
attributes to that insect the size only of Sinodendron cylindricum 
which is certainly less than half the magnitude of our insect. It 
also resembles the Janus of Panzer, but is much larger. 

The thoracic tubercles of the female are almost obsolete, and 
the horn of the head is transverse and much shorter than the 
head, but the other external characters are the same as those of 
the male.

2. C. HISTEROIDES.—Dark cupreous ; clypeus emarginate; an- 
tennz yellowish. 

Inhabits the United States. 

Scarbeeus histeroides Knoch in Melsh. Catal. 

Body punctured; above dark cupreous; beneath blackish-cu- 
preous: clypeus with the punctures obsolete behind, and more 
distinct before; an impressed line from the anterior canthus of 
the eye to the lateral edge; anterior edge bidentate, teeth 
slightly elevated and separated by an emargination: antenne 
yellow: thorax with an abbreviated impressed line from the 
middle nearly to the base, nearly obsolete on the disk and [206] 
anteriorly ; lateral submargin with an impressed dot; lateral 
edge not angulated; elytra striate; strie profound, slightly pune- 
tured ; interstitial lines flat and impunctured; anterior tibia 
with series of yellowish cil; exterior edge four-toothed, the 
posterior tooth minute or obsolete ; terminal spine acute. 

Length more than one-fourth of an inch. 

This insect, which occurs in Pennsylvania, [ also obtained on 
the Mississippi near Cape Gerardeau. 

[Belongs to Cheridium and is the same as Ateuchus capistra- 
tus Fab.—LEc. ] 


3. C. TRIANGULARIS.—Cupreous ; head horned; thorax angu- 
lated; elytra striated and punctured. 

Inhabits Arkansa. 

Body dark reddish-cupreous: clypeus reticulate, margined with 
black; horn as long as the thorax, recurved, black: thorax 
minutely scabrous, with a depressed triangular plane upon the 
surface ; the lateral angles very prominent; a large submarginal 
lateral puncture : elytra regularly striate, with impressed slightly 
punctured lines; interstitial spaces punctured. 

Length less than four-fifths of an inch. 

This species is somewhat larger than C. carnifex, to which it 
is closely allied, but differs in color, in haying an impressed strie 
upon the elytra, and punctured interstitial spaces; whereas in car- 
nifex the sides of thorax and the elytra are green, and the latter 
have elevated striz, and irregular elevated abbreviated lines on 
the interstitial spaces.

1. A. nIGRIcoRNIS.—Black, minutely scabrous; clypeus six- 
toothed, incisure of the posterior tooth much less profound than 
that of the preceding one; anterior tibia three-toothed. 

Inhabits the United States. 

Body deep black, immaculate, slightly scabrous with elevated 
points or minute lines; head with cupreous reflexions: clypeus 
six-toothed ; the two anterior teeth more prominent, flattened, 
conic, slightly recurved; lateral ones smaller, more like serratures ; 
the exterior one much the smallest, and separated from the pre- 
ceding tooth by a slight incisure : antennz black; thorax con- 
vex, with cupreous reflexions ; an obsolete, indented, longitudinal, 
obtuse line, near the base; posterior edge regularly arquated ; 
lateral edge angulated in the middle ; anterior margin profoundly 
emarginate for the reception of the head; elytra with numerous 
elevated points, and with obsolete impunctured striz: anterior 
tibia dentate upon the exterior edge, the three terminal teeth 
large. 

Length more than one-fourth of an inch. 

I observed this species near Cape Gerardeau, and in the inter- 
mediate country between that town and the Rocky Mountains ; 
and as I formerly obtained two specimens in New Jersey, I think 
it probable that it inhabits a principal portion of our country ; 
but it does not seem to be common anywhere. Those I ob- 
served in New Jersey were busily engaged in [208] rolling a 
small pellet of hog dung, which, however, was not shaped in the 
spherical form.

2. A. opsoLETUS.—Cupreous polished; clypeus bidentate 
before ; elytra obsoletely striated. 

Inhabits near the Rocky Mountains. 

Body entirely cupreous, polished, immaculate, with very 
minute punctures: clypeus slightly margined anteriorly with 
dull green ; an oblique, slightly impressed, glabrous line before 
the eye; edge bidentate before, and with an obsolete remote 
tooth each side before the eyes: antennz blackish: thorax a 
little angulated each side on the edge: elytra obsoletely striated.

Length nearly one-fifth of an inch. 

This species was obtained on the river Platte near the Moun- 
tains. The punctures are so minute as not to be visible, but 
with the aid of a strong magnifier. ; 


3. A. EBENEUS [EBENUS].—Black ; clypeus six-toothed ; inci- 
sure of the posterior tooth as profound as that of the preceding one. 

Inhabits Missouri. 

Body deep black, immaculate, scabrous, with slightly elevated, 
very numerous points: clypeus six-toothed; the two anterior 
teeth hardly more prominent; the fissure separating the poste- 
rior tooth more acute, and as profound as that of the preceding 
tooth: thorax convex; an obsolete, indented, longitudinal, ob- 
tuse line towards the base ; posterior edge perceptibly projecting 
into a slight angle in the middle, lateral edge angulated in the 
middle, and with irregular denticles behind the middle: elytra 
with [209] obsolete impunctured strive: anterior tibia with three 
large teeth. 

Length two-fifths of an inch. 

This species very much resembles the preceding, from which 
it is, however, distinguishable by its superior magnitude, by the 
much more numerous small tubercles with which its surface is 
overspread, and by the much more profound fissure which sepa- 
rates the two posterior teeth of the clypeus from each other; 
from this fissure a distinct line passes upwards and intersects a 
similar transverse line drawn from the inner canthus of the eye, 
as in many species of this genus. 


SCARABASUS Latr. 


S. TRIDENTATUS.—Clypeus with an elevated tridentate line 
on the anterior submargin. 

Inhabits Arkansa. 

Body black, punctured: clypeus scabrous; an obsolete elevated 
abbreviated line in the middle; an elevated transverse tridentate 
line on the anterior submargin, confluent each side with the 
lateral reflected edge ; tip much narrowed, emarginate, reflected : 
thorax, punctures generally diffused: scutel impunctured : elytra 
with punctured striz: beneath reddish-brown. 

Length three-fifths of an inch. 

The maxillz of this insect are horny, and dentated at tip, but 

[ Vol. IIL.

the mandibles are short, unarmed, ciliated on the interior and 
exterior sides, and not [210] prominent; the labrum also is con- 
cealed; the labium is conical and prominent, and the tongue is 
concealed. The extremity of the clypeus has very much the ap- 
pearance of the labrum, as the elevated and dentated line resem- 
bles a reflected termination of the head. 

A single specimen was brought from the Arkansa by Mr. 
Thomas Nuttall.

1. G. EXCREMENTI.—Black-bronzed, mutic; an impressed rec- 
tangular line on the clypeus. 

Inhabits the United States. 

Scarabzus excrementi Knoch in Melsh. Catal. 

Body above black bronzed, punctured; beneath dark violace- 
ous: clypeus confluently punctured; summit destitute of punc- 
tures ; three very obtuse slightly elevated tubercles, of which one 
is above each eye, and consists of a more elevated portion of a 
raised line, which passes from above the eye to the edge of the 
elypeus, another tubercle is situated upon the middle; a pro- 
foundly impressed, abbreviated, longitudinal line between the 
eyes, which divaricates anteriorly into two lines that terminate at 
the tip of the elevated lateral line: thorax densely punctured 
each side, punctures rare on the dish; an impressed longitudinal 
obsolete line, from the base to the middle; an indented, obsolete 
spot on the lateral submargin, distinguished by more dense punc- 
tures; elytra profoundly striate, striz slightly crenate on the 
inner sides. [211] 

Length about eleven-twentieths of an inch. 

This species is common in various parts of the United States. 
It is found in Pennsylvania, and I obtained specimens at Engineer 
Cantonment, and at Cape Gerardeau. 

The tubercles of the head are not more distinct than those of 
S. stercorarius. 

It strongly resembles S. splendidus of Fabr., miarophagus of 
Knoch, but differs from both in color, and from the latter, which 
it more closely resembles, by having the thoracic punctures less 
numerous, not so much dilated or so profoundly impressed; the

136 ACADEMY OF NATURAL SCIENCES 


color of the miarophagus is dark piceous above and beneath, the 
legs are slightly violaceous. 

It is very probable that the excrementi is allied to the Black- 
burntii of Fab., if not the same. 


2. G. FILICORNIS.—Rufous; thorax tridentate; clypeus with 
an elongated horn. 

Inhabits Upper Missouri. 

Body pale brownish-rufous: clypeus, anterior and lateral mar- 
gins punctured, entire; horn elongated, linear, slightly recurved 
and compressed, longer than the greatest breadth of the head: 
thorax unequal ; three tubercles, placed in a transverse series, the 
exterior ones compressed and longitudinal ; intermediate tubercle 
transverse subemarginate; an indented line behind the middle 
tubercle, and a concavity each side: scutel triangular: elytra 
with punctured strize. 

Length one-fourth of an inch. 

I obtained it near the Council Bluff on the Missouri. Mr. T. 
Nuttall obtained specimens on the Arkansa. Belongs to the 
genus Odonteus Megerle. [212]

Body above deep black immaculate, punctured: clypeus densely 
punctured, with a very slightly elevated, obtuse, obsolete, central 
tubercle; anterior edge very obtusely and widely emarginated : 
thorax densely punctured in every part, excepting upon the ante- 
rior edge which is of a pale color: elytra profoundly striated, 
striz crenated; interstitial lines minutely punctured: beneath 
pale reddish-brown : pectus and antenne blackish: postpectus and 
venter punctured. 

Var.a. Elytra with a few obsolete hardly perceptible rufous

2. A. sTRIGATUS.—Black, clypeus convex on the disk; feet 
dark piceous. 

Inhabits the United States. 

Scarab. strigatus Knoch in Melsh. Catal. 

Body deep black, immaculate: clypeus with very minute punc- 
tures and larger ones at the base; anteriorly emarginate ; middle 
of the disk convex: thorax with rather large punctures, which 
are remote on the disk and more numerous each side ;. posterior 
angles very obtusely rounded: elytra profoundly [213] striated, 
striz punctured ; interstitial spaces convex: beneath black: feet 
piceous towards their extremities. 

Length nearly one-fifth of an inch. 

Rather a common species; it is found in Pennsylvania and as 
far west as the Rocky Mountains. It is longer in proportion to 
its width than A. terminalis.

3. A. TERMINALIS.—Black, tip of the elytra and feet rufous ; 
celypeus trituberculate. 

Inhabits the United States. 

Scarabzus stercoreus Melsh. Catal. 

Body black: clypeus with numerous distinct approximate 
punctures ; three small tuberculi, placed in a transverse line, the 
intermediate one rather largest ; anteriorly emarginate : thorax 
punctured, punctures subequal and equally distributed ; posterior 
angles subangulated, not obtusely rounded: scutel slightly ele- 
vated into a longitudinal line on the posterior disk: elytra with 
punctured striz; interstitial spaces perfectly flat; tip with a 
large, common, obscure, rufous spot, sometimes obsolete, or di- 
vided into two distant ones : beneath blackish : feet rufous black- 
ish at base. 

Length more than three-twentieths of an inch. 

The term ‘stercoreus of Melsh. being preoccupied, I have ap- 
plied to this species that of terminalis. It is readily distinguish- 
able from our other species by the trituberculate clypeus, and the 
uniformly distributed punctures of the thorax.

Body black: clypeus truncate or slightly emarginate at tip: 
thorax punctured, lateral margins rufous, posterior angles obtusely 
rounded : scutel blackish : elytra rufous, immaculate, striate, the 
strie punctured : interstitial spaces very minutely punctured and 
but slightly convex: beneath blackish-piceous : feet rufous. 

Length more than three-twentieths of an inch. 

Var. a. Anterior and lateral margins of the clypeus rufous. 

This species is an inhabitant of Pennsylvania, I also obtained 
specimens of it in the vicinity of Engineer Cantonment on the 
Missouri. It is certainly not the same with the insect which 
Fabricius described under the name of fimetarius, as it is much 
smaller and the clypeus is not tuberculated. I have therefore 
adopted a new name for this species 

5. A. concAvUS.—Thorax impunctured on the disk. 

Inhabits near the Rocky Mountains. 

Body black or rufous ; beneath piceous : clypeus very obtusely 
emarginate before: thorax with rather large distant punctures 
each side; disk, impunctured; posterior angles very obtusely 
rounded : elytra, strie punctured ; interstitial spaces impunctured, 
flat: anterior tibia strongly tridentate. 

Length three-tenths of an inch. 

This species occurred on the Arkansa river near the moun- 
tains. It is about equal in size to “A. oblongus, but will not be 
readily confounded with that insect, as the disk of the thorax 
is impunctured, and the edge of the clypeus is unarmed. The 
lateral thoracic punctures in one specimen are obsolete. [215] 

6. A. oBLonauS.—Black punctured ; clypeus with two tuber- 
cles in the anterior emargination. 

Inhabits the United States. 

Scarabzus oblongus Knoch in Melsh. Catal. 

Body black; beneath blackish-piceous: clypeus punctured, 
punctures confluent before; anterior edge emarginate and with a 
prominent acute tooth each side of the emargination; a trans- 
verse impressed line between the eyes, which is angulated in the 
middle: thorax punctured: elytra with punctured striz, and 
very minute punctures in the interstitial spaces. 

Length three-tenths of an ich. 

This species appears to be common to most parts of the United

States. I have found it in Pennsylvania and near the Rocky 
Mountains. It is readily distinguished from our other species of 
the genus by the bidentate anterior edge of the clypeus and 
striate elytra. 


7. A. FEMORALIS.—Blackish ; margins of the elytra and of 
the thorax pale. 

Inhabits Missouri. 

Clypeus blackish-brown, minutely punctured, anteriorly emar- 
ginate: thorax with small punctures, which are rather more nu- 
merous each side; lateral margins dull yellowish-white, with a 
dusky dot: scutel black : elytra profoundly striated ; strize dilated 
and transversely punctured ; interstitial spaces convex, narrow ; 
color dirty yellowish-white, with a dusky, common disk : beneath 
dark piceous: thighs pale, yellowish-white. 

Length less than one-fifth of an inch. [216]

interstitial lines distinguish it from other species. 


2. T. scUTELLARIS.—Thorax inequal, posterior [239] angles 
rounded; elytra with elevated polished and impressed lines. 

Inhabits Upper Platte. 

Body black, the depressions dusky cinereous: clypeus pune- 
tured, and with two distinct rounded tubercles ; anterior tip an- 
culated ; edge reflected; thorax very unequal, punctured ; lateral 
edge entire; posterior angles very obtusely rounded: scutel an- 
gularly contracted in the middle, acute at tip: elytra with some- 
what capillary impressed striz, and transverse irregular im- 
pressed lines, dividing the surface into irregular longitudinally- 
quadrate, equally elevated, polished spaces ; a few remote punc- 
tures : feet profoundly punctured; anterior tibia with a very ob- 
tuse crenation on the exterior edge. 

Length thirteen-twentieths of an inch. 

This I believe to be our largest species; like its kindred, it 
feeds upon decomposing animal bodies, and is an inhabitant of 
the superior portion of the extensive region through which the 
rivers Platte and Arkansa flow. It may be distinguished from 
its neighboring large species, by the entire lateral thoracic edge, 
and by the equally elevated polished spaces of the elytra.

segments margined with reddish-brown. 

Length rather more thau half an inch. 

Not uncommon in various parts of our country, and is found 
at Council Bluff, on the Missouri, and upon the Arkansa. Mr. 
Melsheimer, in his catalogue, refers to danius and tonkxa ; but 
it disagrees with the descriptions of each of these insects, by 
having a very distinct and rather large scutel, inserted at the base 
into a thoracic emargination. Neither does it agree with the de- 
scription of C. carnifex, to which it has also been referred.

thorax with a transverse dilated excavation before the middle, 
anterior to which is a transverse, elevated, abbreviated line; 
punctures numerous and dense before, sparse behind: elytra 
smooth, simply punctured.

Body pale, punctured, nearly glabrous: clypeus very densely 
punctured above, and sparsely so before ; anterior edge very pro- 
foundly emarginate, the lobes concave above: thorax with nu- 
merous, slightly indented, irregular punctures; posterior angles 
subacute : scutel rounded at tip: elytra with irregular punctures:

2. M. LANCEOLATA.—Above with small lanceolate hairs or 
scales: beneath hairy. 

Inhabits Missouri and Arkansa. 

Body short, suboval, black or reddish-brown; nearly covered 
above with small lanceolate cinereous scales, which arise from 
impressed punctures : clypeus slightly emarginate, edge reflected: 
thorax a little dilated each side before the middle into a rounded 
angle; posterior angles acute; lateral edge slightly crenated: 
scutel rounded at tip: elytrawith minute elevated points between 
the scale-like processes; from two to four obsolete, subglabrous 
lines: pectus and postpectus downy: venter in the male, having 
a compressed tubercle on the centre of each of the three middle 
segments, and the penultimate segment much indented: nails 
one-toothed near the base. 

Length three-fifths of an inch. 

This insect is very short in proportion to its thickness; and 
the remarkable character of the compressed tubercles on the 
venter of the male readily distinguish it from other species. I 
found this species near the Rocky Mountains. [243 ]

lated; striz none; scutel punctured, [244] hairy, rounded at 
tip: elytra pale testaceous, densely and equally punctured, and 
covered with short, reflected, dense hair, and with longer hair at 
base: pectus and postpectus with long hair. 

Length half an inch. 

An inhabitant of various parts of the United States. I ob- 
served it on the Missouri and Arkansa. It may be readily dis- 
tinguished from our other species by the remarkably hairy ap- 
pearance of the body, and particularly of the head, thorax, base 
of the elytra and breast. I can hardly suppose this species to 
be the frist’s of Fab., although the hairy appearance of the tho- 
rax corresponds with the description of that insect; but the 
elytra are punctured and hairy, and the scutel is not white; 
whereas the elytra of ¢rist/s are said to be glabrous, and the scu- 
tel white.

than wide, densely punctured each side nearly to the tip; a 
longitudinal elevated line; elytra concavely striated, strize con- 
fluently punctured: anterior tibia bidentate. 

Length about seven-twentieths of an inch. 

This insect is beautifully iridescent, and by this character is 
readily distinguishable from all other North American insects of 
this genus that I have seen, with the exception of the M. ricolor

Length less than one-quarter of an inch. 

Knoch’s name micans is pre-occupied. My excellent and in- 
genious friend Mr. John F. Melsheimer, makes the following re- 
marks on this insect in a letter to me: “ This insect is very nearly 
related to ©. sericea, but it is still sufficiently distinct, to entitle 
it to the rank of a peculiar species. It abounds in hilly and 
mountainous situations, where, in the month of May, the time of 
the sexual union of the species, it may be seen flying about 
amongst the whortle-berry bushes, in such profusion, that in a 
very short time any number desired might be collected : whenever 
a female alights upon the surface of the ground, she is imme- 
diately surrounded by a number of males.”

8. M. 10-r1nEATA.—Above covered with a yellowish down ; 
thorax trilineate, and elytra quadrilineate with white. 

Inhabits Missouri. [ 247 | 

Body reddish-brown, covered with a very short spiniforn. 
down: clypeus quadrate, slightly wider at tip and truncate, 
emarginate in the middle; down yellowish, dusky on the tip, and 
whitish above the eyes: antenne pule yellowish-brown, glabrous : 
clava elongated, and composed of seven lamina: thorax wit): 
yellowish-brown, and three longitudinal lines of white down, o/ 
which the lateral ones are interrupted near the anterior tip: 
scutel with white down, and glabrous margin: elytra with yel- 
lowish down ; a common gutural line, and three others upon the 
disk of each elytron of white down ; an abbreviated oblique white 
line from the humerus: pectus and postpectus hairy: feet cas-

nee villages on the Platte; several other specimens, however, 
occurred during our journey to the mountains. Its color varies 
from a light chestnut to a black; but the downy or spiny vesture 
is immutable, though it is very deciduous. 

It seems to be closely allied to the M. occidentalis; but if 
Oliver’s description of that insect be correct, it is sufficiently 
distinct. According to him, that species has sometimes only 
“une ligne [248] longitudinale, blanche, au milieu du corcelet,” 
and the scutel is “ marqué de deux taches blanchatres ;’”’ whereas 
our insect has always three thoracic lines, and but a single scu- 
tellar spot. 

Mr. Nuttall also obtained specimens of this insect on the Ar- 
kansas.

LUCANUS Lin. 


L. PARALLELUS.—Mandibles one-toothed ; elytrastriate, punc- 
tured. 

Inhabits the United States. 

L. parallelus Knoch in Melsh. Catal. 

Body dark reddish-brown, with dilated punctures: mandibles 
with an elevated conic tooth arquated inwards, situated on the 
middle of the superior inner edge, and a smaller tooth on the 
middle of the inferior inner edge ; elytra punctured, striate, striz 
with much dilated punctures; humeral angle mucronate ; tibiee, 
anteriors from four to seven-toothed, interior and posterior ones 
one-spined on the middle. 

Length four-fifths of an inch. 

Female destitute of the tooth of the mandibles. 

Very distinct from LZ. parallellipedus by the striated elytra. It 
is not uncommon in the Atlantic States, and as far west as the 
Rocky Mountains.

Lucanus platycerus Melsh. Catal. 
[Vol. II. 


OF PHILADELPHIA. 147 


Body blackish or dark reddish-brown, tinged with brassy, punc- 
tured: mandibles as long as the head; inner side with a robust 
emarginate tooth at base; an unarmed excavated interval in the 
middle, and a dilated somewhat securiform tip, armed with about 
six small teeth; exterior edge with a rounded lobe at base, and 
eleyated angle near the tip: thorax margined, not distinctly sinu- 
ous before the posterior angles: elytra punctured ; striz almost 
obsolete and punctured: anterior tibia with more than ten inequal 
very acute teeth. 

Leneth two-fifths of an inch. 

Very closely allied to Lucanus caraboides, and may possibly 
prove to be only a variety of that species; but as far as I have 
had an opportunity of comparing specimens, it differs from cara- 
boides in color, in being rather more robust, and in being desti- 
tute of the obtuse sinus or truncation near the posterior angles 
of the thorax, which is observable in that species. The mandi- 
bles of the female are shorter than those of the male, the inner 
edge sometimes merely dilated and rectilinear, [250] terminating 
in an angle near the tip; the lobe on the exterior edge, also, is 
not apparent. 

It inhabits as far west as the Rocky Mountains.

Z. RETICULATA.—Black ; posterior angles of the thorax elon- 
gated; elytra irregularly reticulate. 

Inhabits near the Rocky Mountains. 

Clypeus emarginate before : antenn@ a little larger towards the 
three exterior joints not rounded but truncated at tip, the ulti- 
mate one subacute at tip, precisely resembling the corresponding 
joint of Hurychora as represented by Herbst, (pl. 5.) and not 
larger than the preceding joint: palpi, terminal joint a little 
larger than the preceding one: mentum widely emarginate, nar- 
rower at base, not concealing the base of the maxille so much as 
that of Pimelia bipunctata: thorax curvilinearly emarginated 
before for the reception of the head; punctures very minute, 
distant ; anterior angles obtuse, somewhat prominent; margined 
each side; posterior angles elongated, acute, closely embracing 
the humeral angles: scutel none: elytra with obtuse, elevated, 
irregular, somewhat reticulated lines.

Length nearly three-fifths of an inch. 

Several specimens of this interesting insect occurred under 
dried bison dung near the Rocky [251] Mountains. They were 
generally pruinose, or more or less covered with a whitish powder. 
in form they agree perfectly with the present genus, but the 
mentum is rather too narrow, and the terminal joint of the palpi 
is rather too much dilated to correspond perfectly with Mr. La- 
treille’s character of the genus.

PIMELIA Lat. 


P. rorunpdA.—Black, with a few white hairs; anterior thora- 
cic angles prominent, acute. 

Inhabits Arkansa. 

Body rounded, black, immaculate, with numerous white hairs 
arising from excavated punctures: head, anterior termination 
truncate, and much narrowed by the concavity of the lateral edge; 
over the insertion of the antennze, a prominent acute angle: an- 
tennze blackish-piceous; second, fourth, fifth, and sixth joints, 
equal ; third slightly longer, obconic-cylindric ; remaining joints 
more ovate, two or three terminal ones rather larger, the last 
ucute at tip: palpi dark piceous, terminal joint truncate at tip: 
thorax very short and wide; anterior angles prominent, acute ; 
punctures of the lateral margin much dilated, excavated, con- 
fluent; those of the disk smaller and distinct; lateral edge rec- 
tilinear: elytra with profound, excavated punctures at base, and 
smaller and less indented ones towards the tip. [252] 

Length less than one-fourth of an inch. 

This species we observed only within the distance of a hundred 
miles from the Rocky Mountains. In the form of the body it 
very closely resembles Olivier’s figure of his P. inflata, the P. 
jlavicollis of Fabricius. This new species I believe to be the 
first of this genus that has yet been found on this continent. 
The mentum is proportionally much larger than that of P. bipunc- 
tata, entirely concealing the mandibles even when viewed lateral- 
ly, affording space only for a circumscribed play of the palpi. 
But the antenne differ from those of the bipunctata, which have 
che terminal joint smaller and shorter than the preceding, and 


[Vol. IL. 


OF PHILADELPHIA. 149 


partly included in it; this character, however, Latreille, in the 
Régne Animal, does not state to be essential in this genus. The 
proportion which the terminal joint of the palpi bears to the pre- 
ceding joints, is very similar to that of the palpi figured by 
Olivier, Vol. 3, No. 59, Pl. 1, and although this terminal joint is 
proportionally larger than that of the dipunctata, yet it is not 
more dilated than that of Tentyria glabra, which is admitted 
into the same subdivision with Pimelia. 

The anterior tibize are not dentated like those of Hrodius, but 
are furnished with small spines on the anterior and posterior 
edges; the form of the thorax and abdomen agree with Latreille’s 
definition of Pimelia in the Régne Animal.

AKIS Fab. 


A.? muricatsa.—Black; above with numerous small tuber- 
cles and sete; thorax and elytra with widely reflected margins. 

Inhabits Arkansa at the Rocky Mountains. 

Body oblong-oval, black; superior surface armed with numer- 
ous minute tubercles, from each of which arises a small, recurved, 
ferruginous seta: clypeus not reflected: antenne, third joint 
nearly equal to the two succeeding ones conjunctly ; fourth, fifth, 
sixth, seventh, eighth, joints, obconic-cylindric; ninth, tenth, 
eleventh, rounded, the latter somewhat larger than the preceding 
one, and subacute at its tip: thorax transverse, dilated, and 
widely reflected each side, widest behind; anterior margin very 
profoundly and abruptly emarginated, the emargination receiving 
the head to the origin of the antenne, and rather too narrow to 
admit the free motion of the head upward; lateral edge simply 
arquated ; posterior edge rectilinear in the middle, excavated 
each side; anterior and posterior angles subacute, the latter ex- 
tending far backwards so as to cover the anterior angles of the 
elytra: elytra inseparably united, widely reflected each side and 
behind, the exterior edge continuing the course of the thoracic 
edge, without any indentation between them: wings none: scutel 
minute: tibia armed with minute spines. [254 J

mo. ACADEMY OF NATURAL SCIENCES 


Occurred under dried bison dung, &c., near the Rocky Monn- 
tains. In addition to the above description of the antenne, I 
may add that the four terminal joints are somewhat more dilated 
than the others. The mentum, although broader than long and 
emarginate at tip, is proportionally smaller than that of Scawrus 
striatus, permitting a view of the mandibles to the base; the palpi 
are decidedly more dilated at tip than those of Tentyria glabra ; 
in this respect approaching the family of Blapside. In form it 
seems to bear some resemblance to Hurychora, but the antenne 
are eleven-jointed. As it does not entirely agree with any genus 
the characters of which Latreille has noted, it may be proper to 
remove it to the Blapsida, under a separate genus, which may 
be named Embaphion. It is still more closely allied to Heleus 
by its form, and indeed, if external characters only were to be 
considered, we would certainly be justified in referring it to that 
genus, but the fact of the maxilla being armed with a horny 
nail, excludes it entirely and absolutely from the family of which 
Heleus is a member.

allied to E/eodes than to A/is.—LEc. | 


ASIDA Latr. 


1. A. opaAcA.—Black, opaque, scabrous: thorax with acute 
angles, and lateral reflected margin; elytra subinequal. [255 ] 

Inhabits Arkansa. 

Body black, opaque, scabrous with minute elevated points, 
which furnish very minute polished hairs: antennee, terminal 
joint as small as the second: thorax widely emarginate for the 
reception of the head ; anterior angles prominent ; lateral margin 
dilated, reflected ; lateral edge arquated, excuryed near the base : 
posterior angle very prominent, acute ; posterior edge slightly de- 
flected in the middle, recurved each side towards the angles: 
scutel minute: elytra with a somewhat inequal surface, destitute 
of distinct strize or punctures ; lateral edge acute, a little reflected 
at base ; humeral angles acute. 

Length three-fourths of an inch. 

Found near the Rocky Mountains. The joints of the antenne 
gradually become a little wider and shorter to the terminal one, 
which is less than half the size of the preceding joint. The 


[Vol. III.

mentum is much dilated and at tip emarginate, concealing the 
inferior portion of the maxilla, with the exception of a point 
near their base. The form of the thorax agrees with Axis, but 
agreeably to Latreille’s definition of that genus, it cannot have a 
place there.

2. A. poritA.—Black, polished, glabrous ; thorax with acute 
angles and reflected lateral margin. 

Inhabits Arkansa. 

Body deep black, polished, glabrous; head rugose with con- 
fluent punctures: labrum with [ 256] minute black hairs above 
and rufous ones on the anterior edge: thorax with minute, dis- 
tant punctures; anterior edge concave; anterior and posterior 
angles acute, not prominent; lateral margin reflected, the edge 
arquated, not excurved near the base; basal edge nearly recti- 
linear: scutel minute: elytra slightly and irregularly rugose, 
destitute of punctures or impressed lines; exterior edge promi- 
nent and reflected near the base, rounded towards the tip ; hu- 
meral angles acute. 

Length more than half an inch. 

Like the preceding species, and several of the Blaps, this spe- 
cies occurs under dried bison dung in the extensive region bor- 
dering the Rocky Mountains. The antennze and mentum are 
similar to those of A. opaca.

smallest and rufous: thorax, angles subacute, anterior edge con- 
cave; lateral margin hardly reflected; edge arquated, very 
slightly excurved near the base: basal edge rectilinear: elytra 
each with three profound and concave grooves at the base, of 
which the sutural one extends to the tip, and the two others 
terminate beyond the middle, [257] at the origin of two other 
much abbreviated grooves, which are confluent before the tip :

thorax and abdomen. Under bison dung with the foregoing 
species. 

The terminal joint of the maxillary palpi of these three species, 
corresponding in its dilatation and form with the definition of 
the Fabrician genus Blaps by Mr. Latreille, in the Regne Ani-

they are most closely related, though the form of the body 
perhaps better agrees with Axis.

It is very possible that under this specific denomination, I

hairs: thorax subquadrate, punctures smaller than those of the 
head and more distant ; lateral edge regularly arquated ; anterior 
edge very slightly concave; posterior edge nearly rectilinear, a 
little arquated each side near the angles which are obtuse : scutel 
convex, impunctured: elytra destitute of strie, or distinctly 
regular series of punctures; scabrous with minute slightly ele- 
vated points, each of which precedes a puncture; lateral margin 
rounded. 

Length about half an inch. 

This species occurs in the country of the Arkansa and Platte, 
near the mountains. Mr. Nuttall also obtained specimens on the 
Upper Missouri. It is somewhat similar to the preceding species, 
but is shorter, and the sculpture of the elytra sufficiently distin-

Length about a quarter of an inch. 

This species resembles the male of dimidiatus Fab., and hume- 
ratus Fab., but the vertex of those two species, although con- 
siderably elevated, is rounded at tip, and the former has a robust 
spine over the middle lobe of the posterior margin of the thorax. 

[I have proposed for this species the name R. Say, 
(Journ. Acad. Nat. Se. 2nd ser. 4, 21), for the following reasons: 
The name proposed by Say was pre-occupied by Olivier; Dr. 
Melsheimer on this account substituted the name R. ambiguus, 
but described under that name a variety of 2. pectinatus Fabr., 
(varicolor Gersteker). Although Gersteecker has placed R. 
bicolor Ol. as a synonym of F. bimaculatus, this does not obviate 
the necessity of changing the name imposed by Say under a 
belief that the name was free. This species is cited by Gersteee- 
ker asa synonym of his 2. varicolor, but it differs very much 
from that species by the anterior face of the vertex being flat- 
tened, and the posterior margin so broadly rounded as to appear 
truncate, as above noted by Say.—Lec. ] [276 |

MELOE Linn. Latr. 


1. M. AnGusticoLtuis.—Thorax narrower than the head; 
elytra and abdomen violaceous. 

Inhabits Pennsylvania. 

Body dark violaceous, punctured: head with profound pun- 
tures, an impressed, longitudinal, abbreviated, acute, frontal line ; 
and a transverse, elevated, obtuse one connecting the bases of 
the antenne: thorax slender, narrower than the head, profoundly 
punctured, widest rather before the middle, and narrowed at tip 
and base ; base emarginate, and slightly margined : elytra rugu- 
lose, dark bluish-violaceous: feet slightly hairy, spines [281] 
of the tibia, and nails ferruginous: abdomen slightly rugulose, 
dark greenish, or violaceous: tergum each side black, opaque. 

A rare species, very distinct from the JM. americana of Leach, 
which is not uncommon, and is sometimes gregarious in great 
numbers; the thorax of angusticollis is strikingly narrower pro- 
portionally, as well as the head, than the body; and the colors of

regular. 

Inhabits Missouri and Arkansa. 

Body black, opaque, punctured ; punctures crowded, concave,

with separated punctures on the anterior part of the front, distant 
ones on the clypeus, and remote ones on the labrum: antenne 
regular: thorax as wide as the head, emarginate at base; sides 
very slightly arquated, hardly narrower at base ; a longitudinal, 
dorsal, acute, impressed line: elytra scabrous, with minute 
elevated points, and numerous short black hairs. 

Length, male half, female four-fifths of an inch. 

Perfectly distinct from the preceding species, and from the 
americana, by the very dense and equally distributed punctures 
of its head and thorax, [282] and by its minutely scabrous 
elytra. Found in the vicinity of Council Bluff, and near the 
Rocky Mountains.

4. L. Nurratii.—[Ante, 1, 5.] [301 | 

The antennz of this species in the proportional length of the 
second and third joints, are similar to those of the genus Zonitis, 
as defined by Latr., Régne Animal, and together with those of 
the species aenea, polita, sphzricollis and reticulata, are consider- 
ably different from those of many of the other species of this 
genus, being somewhat thicker towards the tip, but are much 
shorter than in Zonitis; these characters, combined with form of 
the terminal joint, approach them to the genus J/ylabris; but 
the antennz are not arquated at tip, and are of a more consider- 
able length ; the habit also differs, the form of the body being 
more elongated. These four species then, seem to have the 
habit of Lytta, combined with a form of antennz approaching 
somewhat to that of Mylabris. They cannot be referred to 
Zonitis, as the palpi are not filiform, and the habit differs. 

First observed by Mr. Thomas Nuttall on the Missouri. I 
found them on one occasion near the Rocky Mountains in great 
numbers; small bushes of various kinds were loaded with them.

Very much resembles the preceding species, but differs by 
many characters, particularly in the form of the thorax, in the 
color, polish, and hair of this part and the head, in the form of 
the antenne, Xe. 

In the bilobate form of the labrum, these two species differ 
from the other species of this genus; their palpi are somewhat 
similar to those of Zonitis and Nemognatha, but the second joint 
of the antennz is minute, and the body is elongated.

second joint equal to the third: palpi obscure reddish-brown ; 
thorax with a longitudinal impressed line, not narrowed behind : 
tibia with sparse hairs: tarsi with black hairs. 

Size of the preceding, to which it is very similar in form, and 
of which it may very possibly be a variety. Found near the 
Rocky Mountains. The color of the hair, with which the body 
is covered, is very similar to that of LZ. ferruginea, but that 
insect is very different in the proportional length of the an- 
tenn. [ 305]

Found near the base of the Rocky Mountains, and between 
the rivers Arkansa and Platte. 

The genera Zonitis and Nemognatha are similar to the genus 
Hloria in the form of the tarsi, which are bifid and pectinated, 
in this respect widely differing from Lytta, &e., of which the 
tarsi are simply bifid. 

2. N. mintma.—Testaceous ; head and thorax elongated; post- 
pectus black.

in general form it approaches P. cylindricus, but the thorax is 
broader and destitute of spiniform teeth; the third joint of the 
antennz is obviously shorter than the first, and the tibize are 
densely ciliated on the inferior edge. It is probably somewhat 
allied to the P. dentatus of Fabricius, judging from the descrip- 
tion of that author.

LAMIA. 


1. L. AcuLIFERA.—Thorax unequal; elytra aculeate, with a 
white band behind. 

Inhabits Missouri. [330] 

Body blackish-brown, covered with short, prostrate, cinereous 
hair: head with a double slightly elevated line on the vertex : 
antennee as long as the body, cinereous, spotted towards the base, 
and annulated towards the tip with brown: thorax unequal; a 
dorsal, rectilinear, elevated line, and two undulated or interrupted 
ones ; lateral tubercle obtuse, little elevated: elytra unequal, with 
numerous, elevated, acute points ; behind the middle a white fas- 
cia broadest at the suture, and edged behind by a black line: tip 
entire: thighs clavate, spotted, and tibia biannulate with black- 
brown. 

Length seven-twentieths of an inch. 

This is a common species. I observed it on the banks of the 
Mississippi; Missouri, Platte (Nebraska) and Arkansa.

2. L. aspersA.—Covered with cinereous hair; elytra with 
numerous black dots. 

Inhabits Mississippi and Missouri. 

Body reddish-brown or blackish, covered with cinereous hair : 
head black : antenne longer than the body: thorax with a small, 
acute, reflected spine behind the middle each side, and with two 
er four black dots above placed in a transverse series, the two 
intermediate ones larger : elytra reddish-brown, with numerous 
black dots; tip emarginate, bidentate: beneath black, covered 
with cinereous hair: thighs clavate, pale reddish-brown at base. 

Length less than one-fourth of an inch. [331] 

This insect is not uncommon in the western regions. It varies 
a little in having the black elytral spots smaller, or in having 
some of them which are situated behind the midde, confluent 
into a band. I have taken a specimen of this insect near Phila- 
delphia, at Harrowgate, the seat of my friend Mr. J. Gilliams, 
in a rye field.

MONEILEMA* Say. 


Essential character.—Hlytra undivided ; wings none. 

Natural .character—Body convex: head vertical: antennz 
eleven-jointed, [404 ] setaceous, inserted into a profound emargi- 
nation of the eye; first joint elongated, robust ; second joint very 
short, third nearly as long as the first; remaining joints gradu- 
ally diminishing in length to the tip: eyes rather small, pro- 
foundly emarginate: labrum prominent, rounded: mandibles ro- 
bust, emarginate at tip: palpi, terminal articulation as robust as 
the preceding one, rounded at tip: labiales inserted near the base 
of the labium: labium prominent, bifid; lobes rounded : elytra 
consisting of one piece, convex, subovate, narrowed behind, sub- 
truncate at tip, and rather shorter than the abdomen: epipleura 
dilated, encasing the abdomen each side: feet robust: thighs 
clavate.

Body glabrous, black : antennz shorter than the body, obso- 
letely annulated with cinereous: front impunctured: thorax 
slightly punctured at base and each side; a lateral, small, sub- 
acute tubercle: scutel rounded at tip; elytra with numerous, in- 
dented, irregular, longitudinal, abbreviated, confluent lines; a 
few distant punctures towards the base. 

Length four-fifths of an inch. 

This singular insect I found near the Rocky [405] Mountains, 
and in the vicinity of the rivers Platte (Nebraska) and Arkansa. 
Mr. Nuttall also obtained specimens on the Upper Missouri. 

It is essentially distinct from the genus Lamia, (to which it is 
most closely related,) by the total absence of wings, and by having 
the elytra inseparably united into one piece. The epipleura em- 
brace the sides of the abdomen, as in the genus Pimelia, Xe. 
and its gibbous or convex form and somewhat pointed abdomen 
give to it almost the habit of some species of that genus. 


SAPERDA. 


1. 8. AtreRNATA.—Blackish, with cinereous hair and ferru- 
ginous spots; thorax long. 

Inhabits the United States. 

Body blackish-brown, with sparse, cinereous, prostrate hair, 
varied with spots and lines of dense ferruginous hair: head, with 
the edge around the antennz, much elevated, somewhat spinose 
on the inner side; between the antenne profoundly indented : 
antenne longer than the body, attenuated: thorax cylindric, 
rather long, narrower than the elytra; with four ferruginous 
lines ; elytra with three or four series of irregular, ferruginous 
spots : tip rounded. 

Length, male seven-twentieths, female nine-twentieths of an 
inch. 

The marginal and sutural series of elytral spots [406] more 
regularly alternate with the intervening colors than the inter- 
mediate series do. 

It somewhat resembles Olivier’s figure of S. maculata, but 
the thorax is much shorter, and the spot are differently disposed.

2. S. punctrcotiis.—Yellow; beneath plumbeous; elytra 
black, with a yellow margin and suture. 

Inhabits Arkansa. 

Body covered with bright yellow, crowded, short, prostrate 
hair: head with a black, frontal dot, and another upon the vertex: 
antenne as long as the body, black: thorax with four black, 
equal spots above, and one each side: elytra black and punctured 
upon the disk; exterior margin, tip, and suture with an equal 
line of dense yellow hair; tip entire: beneath plumbeous. 

Length seven-twentieths of an inch. 

A very pretty insect, of which but a single specimen was found 
by Mr. T. Nuttall on the Arkansa. 

[Afterwards described as S. trigeminata Randall.—L«c. } 


3. S. ocuLATICOLLIS.—Black, covered with cinereous hair: 
elytra truncate at tip. 

Inhabits Missouri. 

Body black, immaculate, cylindrical, covered with short pros- 
trate hair, which partially conceals the punctures: palpi piceous ; 
antenne rather shorter than the body : thorax cylindric, diameters 
nearly equal; two small glabrous spots on the disk, and an obso- 
lete, glabrous, longitudinal line; elytra truncate at tip. 

Length nine-twentieths of an inch. 

[Belongs to Oberea.—LeEc.] 


4, S. rvornata.—Black, covered with cinereous hair; an- 
tennz annulate; elytra entire. 

Inhabits Missouri. 

Body black, immaculate, cylindrical, covered with short, pros- 
trate hair, which conceals the punctures: palpi black: antennx 
rather shorter than the body, and, excepting the basal joints, an- 
nulate, with cinereous and black: thorax cylindric, diameters 
subequal : elytra entire and subacute at tip, which is equally at- 
tenuated from the suture and exterior margins. 

Length less than nine-twentieths of an inch. 

The entire termination of the elytra sufficiently distinguishes 
this species from the oculaticollis, and it is also a more robust 
species ; it is, however, still more closely allied to the S. pergrata, 
but in addition to the difference in the color of the femur, and 


that of the margins of the elytra, the elytra are much less obtuse

at tip, and the thorax is entirely destitute of glabrous spots. It 
cannot be the cinerea Oliy., as the antenne of that insect are de- 
scribed to be as long again as the body. 

[I have not identified this insect.—Lxc.] 

5. S. PERGRATA.—Black, covered with cinereous hair; an- 
tenn annulate ; elytra entire ; thorax with small glabrous spots. 

Inhabits Missouri. 

Body black, covered with short, prostrate hair, which partially 
conceals the punctures: antenne nearly as long as the body, an- 
nulate, with cinereous and black: thorax slightly dilated in the 
[408 | middle ; a transverse, arquated series of four glabrous 
spots, and a longitudinal, abbreviated, glabrous line behind the 
middle : scutel whitish: elytra with a narrow white margin and 
suture; tip entire: thighs dull rufous. 

Length about nine-twentieths of an inch. 

Upon the middle of each elytron is a very indistinct, rufous 
line, which is only visible upon close inspection, and is very 
probably often wanting; a similar spot is upon the anterior por- 
tion of the thorax; the white appearance of the margin of the 
elytra is occasioned by the more dense disposition of the hairs on 
* that part. We captured but a single specimen on the Platte 
river (Nebraska) near the mountains. 

[Belongs to Stenostola.—Lxc. ] 

6. S. cALCARATA.— Reddish-brown, covered with cinereous 
and yellow hair; elytra mucronate at tip. 

Inhabits Missouri Territory. 

Body clothed with dense, prostrate, cinereous hair, varied with 
yellow or somewhat ferruginous hair: front, a geminate line on 
the vertex and lateral line, yellow: antennz cinereous, longer 
than the body: thorax trilineate with yellow: scutel yellow, 
sub-emarginate behind: elytra cinereous, varied with yellow-fer- 
ruginous lines and spots; numerous small glabrous punctures ; 
tip mucronate in the middle ; humerus rather prominent. 

Length nearly nine-tenths of an inch. 

Closely related to S. mutica. [409]

‘slightly tinged with bluish: thorax light brown, with two broad, 
white lines approaching before: elytra light brown, irregularly 
punctured ; a broad, white, longitudinal line on each, nearer to 
the suture than to the outer edge. 

Length from one-half to seven-tenths of an inch. 

A very pretty insect. Inthe larve state it is very injurious to 
the apple tree; boring into the wood. 

[Previously described by Fabricius as S. candida.—LEc.] 

8. 8S. murica.—Reddish-brown, covered with cinereous and 
ferruginous hair; elytra mutic; antenne annulated. 

Inhabits Missouri Territory. 

Body dark reddish-brown, partially covered with cinereous- 
yellow, prostrate hair, varied with ferruginous hair: front, anda 
geminate line on the vertex, ferruginous : antennz annulate, with 
cinereous and blackish ; shorter than the body : thorax trilineate, 
with ferruginous : scutel yellow, subemarginate behind: elytra 
with yellowish-cinereous hair, varied with ferruginous spots; 
numerous glabrous punctures ; tip mutic, obtusely sublanceolate. 

Length half an inch. [410] 

Very much resembles S. calcarata, and may possibly prove to 
be a sexual variety, nevertheless the differences are remarkable ; 
in the present insect the antenne are shorter than the body, and 
annulated, and the elytra are destitute of a spinose point at tip.

Very much resembles C. foenicum, but is much smaller, and 
the elytra are very obviously punctured. We obtained speci- 
mens on the Arkansa river; it is also an inhabitant of Pennsyl-

body: palpi piceous: [414] thorax with dense, minute hairs ; 
two elevated, obtuse tubercles behind the middle and an inter- 
mediate, elevated line, obsolete before: scutel hairy, rounded : 
elytra violaceous, scabrous, with minute, subequal, numerous 
tubercles ; base dusky, with minute hairs; two or three longi- 
tudinal, elevated, white lines on the middle, nearly parallel, and 
placed in an obliquely transverse series; tip obtusely rounded : 
thighs clavate. 

Length, male nine-twentieths ; female seyen-tenths of an inch 
nearly. 

I found a specimen in Pennsylvania some time since, and re- 
cently an individual occurred on the Arkansa river. The white 
lines of the elytra are very short, and nearly parallel to each 
other ; nearer to the base is sometimes another abbreviated white 
line.

longitudinal, blued-black lines on the disk of each: beneath 
black ; sides of the pectus, margins of the ventral incisures, and 
middle of the thighs, rufous. 

Length two-fifths of an inch. 

This insect, which is not very uncommon in the vicinity of 
Council Bluff and the Pawnee villages, bears some resemblance 
to the vittata of Swederus in Stockh. Trans. 1787, p. 198, and of 
Hellwig in Melsh. Catal., but in that insect there is but a single 
elytral vitta. In many other characters it is widely distinct, 
and approaches somewhat in [417] character to the genus Rha- 
gium. It varies in having an immaculate thorax and rufous 
clypeus.

2. L. CYLINDRICOLLIS.—Sericeous, rufous; elytra, tibia, and 
tarsi blackish. 

Inhabits the United States. 

Rhagium sericewm Knoch in Melsh. Catal. 

Body sericeous, yellowish-rufous: head with a longitudinal, 
indented line, and a transverse, elevated one between the antennex: 
antenne rather longer than the body: palpi blackish: thorax 
long, subcylindric, with a longitudinal, dorsal, and anterior and 
posterior, impressed, submarginal lines: elytra blackish, attenu- 
ated rectilinearly or somewhat concavely from the prominent 
humerus to the obliquely emarginate or bidentate tip: feet ru- 
fous: knees, tibia and tarsi, black. 

Length, male more than half an inch; female more than 
three-fifths. 

In the male the head is often dusky, and the thorax, with the 
exception of the more eleyated part, and the coxe, are blackish. 

In the general appearance of the head and thorax of this 
insect, it is closely allied to the genus Rhagium, and has been 
referred to that genus by Mr. Melsheimer in his Catalogue ; 
but as the thorax is destitute of armature, and the antennz are 
longer than the body, I prefer giving it a place in the present 
genus, agreeably to the generic characters of Latreille and Leach. 
[ think it ought [418] to form a distinct genus, together with 
Rhagium trivittatun.

Body elongated, pale rufous, sericeous : head with an obsolete, 
impressed line: antennz as long as the body: thorax conical ; 
posterior angles acute: elytra black, attenuated; with numerous 
short, prostrate, black hairs; tip very obliquely emarginate, ap- 
pearing mucronate: wings black. 

Length from half an inch to three-fifths. 

This species is found in Pennsylvania, and on the Ohio and 
Mississippi rivers. It may be allied to the L. bicolor of Swede- 
rus in Stockholm Trans. 1817, p. 197, but his insect is said to be 
black on the upper part of the tail, a character which our insect 
does not possess. In Turton’s translation of the Syst. Nat., the 
name bicolor of Swederus is changed to bicolorata, so that Mr. 
Melsheimer’s designation may be retained for the species here 
described.

confluently punctured ; punctures dilated; a transverse groove 
on the hind margin: scutel small, black: elytra rufous or dull 
brick red; punctures numerous, becoming smaller to the tip, 
which is emarginate, mutic: beneath black: abdomen rufous; of 
the female, black.

thorax rounded or subovate; a transverse groove on the posterior 
margin, and an impressed line on the anterior margin: elytra 
testaceous, with very short, yellowish hairs; tip black, truncate 
on the edge: beneath, with long hair on the pectus, and short 
hair a little sericeous on the postpectus and yenter: tail entire. 

Length less than three-fifths of an inch. 

Var. a. Elytra testaceous, destitute of the black tip. 

I have not seen this insect in Pennsylvania. It seems to be 
very closely allied to ZL. tomentosa Fab., but is larger, more 
robust, and the tail is not [421] emarginate as that of tomentosa.

rufous: labrum and mouth pale rufous: thorax rufous, subglo- 
bose in the middle, and with a flattened, anterior, and posterior 
margin: elytra not tapering, confluently punctured, [422] black, 
entire at tip: beneath sericeous: feet varied with testaceous. 

Length less than three-tenths of an inch. 

In the distribution of colors it approaches L. thoracica Fab., but 
isa much smaller species. It is also very different from the co/- 
laris Linn. of Europe, in being smaller and of a more slender 
form. 


RHAGIUM Fabr. 


1. R. rrrvirrarum.—Black ; elytra with black suture, yel- 
low vitta, black central line, and rufous margin. 

Inhabits Mississippi. 

Head black: clypeus, mouth and antenne rufous: thorax 
uneven, very little narrowed before; an anterior and posterior 
impressed band, and a dorsal, impressed line: scutel black: ely- 
tra hardly emarginated; humerus prominent; suture black,

broader near the base ; a broad, yellowish vitta hardly reaching 
the tip; a black line from near the base separates the vitta from 
the rufous margin : body, beneath black, with golden pubescence ; 
feet and abdomen rufous. 

Length seven-tenths of an inch. 

The body is sometimes rufous. In the disposition of colers on 
its elytra, this species probably bears some resemblance to R. cur- 
sor. It is certainly generically distinct from R. lineatum, which 
[423] is the only true Rhagium of this country that I have seen, 
though it is highly probable that there is another species. 

[Belongs to Toxotus.—Lxc.] 

2. R. CYANIPENNE.—Black ; antenne and feet testaceous ; 
elytra blue. 

Inhabits the United States. 

Body black, tinged with cupreous, punctured; head densely 
punctured ; a longitudinal, obsolete, impressed line: antennz 
rather shorter than the body, testaceous: trophi piceous-yellow : 
thorax impunctured ; an obtuse tubercle each side: scutel black : 
elytra violaceous-blue ; punctures numerous, small, profound ; tip 
truncate ; humerus rather prominent: feet testaccous. 

Length two-fifths of an inch nearly. 

A rare insect. I obtained a specimen several years since near 
Philadelphia, and recently Mr. Nuttall presented me with a speci- 
men which he captured during his botanical expedition to the 
Arkansa river, 

In form of body, it very much resembles Leptura collaris and 
L. virginea, as figured by Olivier, to which genus I would have 
referred it, but for the small thoracic tubercles.

tel impunctured: elytra with large, rounded, deeply impressed, 
numerous punctures ; apex truncato-sinuate, bidentate: thighs 
clavate ; posterior ones elongated: postpectus and abdomen coy- 
ered with dense, short, incumbent, cinereous hair. 

Length five-sixteenths of an inch.

It is an elongated insect, resembling a Necydalis. The posterior 
thighs are much elongated, and, like the others, are clavated at 
tip.

202 ACADEMY OF NATURAL SCIENCES 


Body reddish-brown, partially covered with short, prostrate’ 
cinereous hair, inequally distributed: trophi pale rufous: man- 
dibles black at tip: antennze longer than the body ; third, fourth, 
fifth and sixth joints terminated each by a spine, the first one 
largest, two-thirds the length of the next joint: thorax with two 
tubercles before the middle, two longitudinal ones at base, and a 
longitudinal line, glabrous : seutel white, with dense hair, divided 
into two lobes: elytra punctured; hair so disposed as to give the 
surface an irregularly maculated appearance ; tip bispinose ; in- 
termediate and posterior thighs bimucronate; the inner spine 
longest. 

Length seven-twentieths of an inch. 

This species is not the S. marylandicus of Fabr., as described 
and figured by Olivier, which is a much larger and more dilated 
insect ; the thighs not mucronate, and the joints of the antennze 
spinous to the tip. It is, perhaps, more closely related to S. 
spinicornis Fab., but that insect is described as having the joints 
of its antenne bispinous at tip. 

It is a common insect in many sections of the United States 
and is by no means rare in Pennsylvania; [428] we obtained 
specimens on the Missouri, Platte, and Arkansa rivers.

preceding species) and a larger spot at tip; beneath black: feet 
pale testaceous. 

Length three-twentieths of an inch.

tures at tip irregularly disposed ; three dilated, somewhat undu- 
lated, rufous fascize : beneath rufous: feet somewhat paler. 

Length about three-twentieths of an inch. 

Found near the Konza river. At first sight it might be taken 
for a variety of C. congestus, of which the spots had become 
confluent into bands, but the much punctured thorax is a dis- 
tinguishing character that cannot in this instance be mistaken. 


4. C. puncTIpES.—Black ; front two-spotted; thorax with 
three spots, and margin rufous; elytra varied with whitish 
spots. 

Inhabits Arkansa. 

Body black, punctured : labrum each side, base of the antenne,

larger ones between the eyes, dull rufous: thorax, anterior and 
lateral margins, two oblique, dilated, abbreviated lines at base, 
and one at tip dull rufous: elytra with punctured strie; basal 
edge, three large marginal spots, of which one is terminal; a 
smaller one on the middle, near the suture, and two or three 
smaller ones near the base, yellowish: thighs with a white ob- 
long spot near the anterior tip: tail with two dull rufous dots, 
and a smaller one each side on the terminal ventral segment. 

Length less than one-fifth of an inch. 

Corresponds in some respects with Olivier’s [439] descrip-

antennee are shorter than the body. It may possibly, however, 
be the same.

robust than the others. 

Size of the preceding. 

The form of this species is very like that of punctipes. Varies 
in having the thorax entirely red, slightly shaded with black;

ous: thighs black. 

Length three-twentieths of an inch. 

Very similar to C. convexa, but is smaller, and the thoracic punc- 
tures are larger. The feet are sometimes entirely rufous. [ 445] 


6. C. 10-norara.—Rufous-brown, hairy; elytra each with 
about six obsolete, black spots. 

Inhabits the United States. 

Body dark reddish-brown, punctured, clothed with short cine- 
reous hair: labrum and base of the antennz yellowish: thorax 
emarginate: elytra with dilated, confluent punctures: humerus 
prominent ; each with a black spot on the middle of the base, 
one on the humerus, a linear, dorsal one near the suture, a fourth 
near the margin, sometimes double, and a double one before the 
tip: thighs with a projecting angle beneath. 

Length less than three-twentieths of an inch. 

A very distinct species; it may perhaps, with almost equal 
propriety, be referred to the genus Lumolpus.

7. C. 6-norata.—Pale ; each elytron with three black spots. 

Inhabits the United States. 

Body pale punctured: front with an obsolete black spot: ely- 
tra with regular series of punctures, which disappear towards the 
tip; a black, linear spot near the base, and two others on the 
middle, which are parallel and approximate, and of which the 
interior one is placed rather further backward: beneath black: 
pectus, feet, and posterior portion of the venter, pale: thighs 
with a slight angle beneath.

black, oblique spot near the base of each, and a larger obliquely, 
quadrate one on the middle; exterior edge black: feet pale: 
thighs with a minute angle beneath. 

Length about three-twentieths of an inch. 

It has considerable resemblance to the preceding.

Body very pale rufous ; head obsoletely punctured ; an indented, 
abbreviated line or spot on the vertex: thorax, punctures small, 
sometimes obsolete: elytra pale testaceous, with striz of pune- 
tures which become obsolete before the tip: beneath pale. 

Length three-twentieths of an inch. 

Very similar to C. 6-notata, but is always destitute of spots 
on the elytra. 

[This and the next belong to Metachroma, as limited by me,

10. C. puBrosA.—Pale rufous; elytra pale testaceous, with a 
black suture dilated at base. 

Inhabits Arkansa. 

This species seems to differ from the preceding, only by hay- 
ing a black suture dilated at base, a black lateral edge on the an- 
terior half, sometimes obsolete, and a black, basal ventral seg- 
ment; the thorax is sometimes obsoletely dotted with black, and 
in one specimen is a small black spot anterior to the middle of 
each elytra; the 6-notata, 4-notata, pallida, and dubiosa may 
possibly prove to be the same species, exhibiting remarkably dis- 
tinct variations in the distributions of its colors. Found near 
the Rocky Mountains. I think it possible that dubiosa may 
prove to be a variety of Crytocephalus canellus Fabr.

216 "ACADEMY OF NATURAL SCIENCES 


Body densely covered with short, robust, cinereous hair, be- 
neath which the surface is dull reddish, inclining to cupreous ; 
punctured: scutel dusky, sparsely hairy: elytra with very small, 
profound punctures, which are more distant from each other than 
the length of their diameters ; tip attenuated equally from the 
suture and exterior edge; a little produced, and terminating 
acutely. 

Length less than two-fifths of an inch. 

Very similar to a smaller species which Mr. F’. N. Melsheimer, 
in his catalogue, names pilosus ; but the elytral punctures of that 
insect are much more crowded. 


CHRYSOMELA of Authors. 

1. C. nyBripA.—Ferruginous ; elytra pale yellow ; suture and

Body yellow: head with a triangular, black, frontal spot : tho- 
rax, two abbreviated, black, approximate lines, divergent before ; 
about six black dots on each side: elytra, suture, and five lines 
on each, black; the interior line is confluent with the suture be- 
hind ; exterior line marginal; three intermediate ones joined or 
approximated at tip: beneath, incisures and three or four series 
of ventral spots black. 

Length two-fifths of an inch. [ 454 } 

Var. a. Elytra white: the two outer intermediate lines are 
united at base and tip. 

This species seems to be not uncommon on the Upper Missouri, 
where it was obtained by Mr. Nuttall and by myself. The 
variety I found on the Arkansa. 


2. D. 8-mAcuLATA.—Bluish-green ; elytra yellow, with a com- 
mon band, and each with a triangular, black spot near the tip ; 
feet purplish. 

Inhabits the United States. 

Chrysomela maculata Melsh. Catal. 

#s trimaculata ? Fab. Syst. Eleut. 

Bluish-green, punctured: antennze and palpi black: elytra 
punctured in double lines, which become confused near the tip ; 
a dilated, black band extending in breadth from near the base to 
the middle, not attaining the lateral edge, and often interrupted 
in the middle of each elytron; a large, triangular spot near the 
tip of each elytron: beneath black-blue ; feet purplish. 

Length two-fifth of an inch. 

A common insect. Mr. Nuttall captured a specimen with the 
band interrupted into small spots, and the triangular spot near 
the tip entirely wanting. 

This species is no doubt closely related to Chrysomela trimacu- 
lata of Fabr., if not the same, which I believe it to be, although 
that insect is said to be a native of South America, and the 
tarsi are not rufous as those of that insect are described [455 ] 
to be. The terminal joint of the maxillary palpi is very short 
and transverse ; in this respect, corresponding in character with 
the palpi of the genus Doryphora, as defined by Mr. Latreille, 
and, although, as in the preceding species, the prosternum is not 
remarkably advanced, I prefer arranging it here.

1. G. coryitI.—Pale yellowish, testaceous; elytra bifasciate 
with blue. 

Inhabits the United States. Illinois. 

Galleruca coryli J. F. Melsheimer’s letter to me. 

Body pale yellowish-testaceous: head with an impressed line 
between the antennze: antenne blackish: labrum hirsute: man- 
dibles black at tip: thorax transversely concave in the middle ; 
anterior angles subacute ; posterior ones rounded : scutel rounded 
at tip: elytra somewhat dilated behind the middle, with numerous, 
minute punctures, a much dilated blue band at base, and a still 
larger one at tip: wings black. 

Var. a. Pale yellowish-testaceous, immaculate. 

Length more than half an inch. 

A very large species; it is considerably dilated behind, and 
has probably considerable affinity with the genus Ador‘um, but 
the terminal joint of the palpi is not truncated. It occurs in 
Maryland [456] and Virginia, on the banks of the Missouri, 
and J. F. Melsheimer informs me that it is so numerous in some 
parts of Virginia, that it completely defoliates, in a short time, 
the Hazel, (Corylus americanus) wpon which it feeds. 

[A species of Celomera.—Lxc. ] 

2. G. TUBERCULATA.—Dull reddish-brown ; a slight tubercle 
at the anterior and posterior angles. 

Inhabits Missouri. 

Body dull reddish-brown, immaculate, with prostrate hairs : 
antennz black, rufous at three basal incisures: thorax with a 
much dilated, slightly indented spot each side, and an inconspicu- 
ous, central line; edge slightly emarginated each side of the pos- 
terior angles, which, with the anterior angles, are somewhat 
elevated, and resemble slight tubercles: elytra irregularly pune- 
tured: knees, tibia, and tarsi black. 

Length one-fourth of an inch. 

This species is remarkable by its dull, and, with the exception 
of the antenne and feet, uniform reddish-brown color; the two 
emarginations near the posterior thoracic angles are so obtuse as 
to be little more than truncations ; the lateral one of which pro-

yellow. 

Length less than one-fourth of an inch, 

The basal joint of the antennze is sometimes yellowish.

Captured by Mr. T. Nuttall on the Mississippi. I also found 
specimens on the Arkansa near the Mountains. It considerably 
resembles G. baccharidis Fab., but, besides its different mark-

lateral one each side, black: elytra greenish-blue, with very 
minute, crowded, and confluent punctures; fillet attenuated, 
arising from the middle of the base, and terminating beyond the 
middle of the elytron, and with the exterior margin and tip yel- 
lowish-brown. 

Length three-tenths of an inch. 

The fillet varies in length, and its breadth sometimes continues 
undiminished to the tip. Captured by Mr. T. Nuttall.

letely punctured, rounded at tip; each with an oval, black spot 
at base, and a larger, oblong one extending from the middle to 
near the tip: pectus and postpectus black.

largest, and colored by a brown fillet which does not attain the 
tip: a brown common sutural line. 

Var. a. Destitute of the fillet and sutural line. 

Length less than one-fifth of an inch. 

I obtained specimens near the Rocky Mountains. The length 
of the antennze in some specimens would authorize the placing 
of it in the genus Luperus, whilst the abbreviation of the third 
and fourth joints resembles those of the genus Adimonia [461] 
of Schrank. This insect varies in being more robust, with the 
antennee shorter than the body, and the elytra, at first view, are 
entirely olive-green ; but on inspection, vestiges of the fillet and 
sutural line sometimes are visible near the base. It is very simi-

The posterior thighs are much less dilated than those of col- 
laris Fabr. 


6. A. 5-virrara.—Yellowish; thorax four or five-spotted : ely- 
tra five-lined. 

Inhabits Missouri. 

Body oblong-oval, yellowish, glabrous: antenne black ; three

line on the middle of the posterior submargin, and a semi-circu- 
lar series of four equal, equidistant, suborbicular black spots : 
posterior edge concave at the scutel: scutel black: elytra with a 
common sutural fillet; each elytron with a fillet originating at 
the humerus and terminating near the tip, and another marginal, 
less [86] dilated filet, confluent with the sutural vitta at tip ;

A. caroliniana Fabr. The head is sometimes black at base, and 
the two intermediate thoracic dots are confluent. 

Found in considerable numbers on the common elder (Sam- 
bucus) and some other plants. On the evening of the 16th of 
June, I observed great numbers of these flying in a south-east 
direction from near St. Louis, obliquely across the Mississippi 
towards an island, the wind at the same time blowing moderately 
from the eastward; the subsequent evening, about the same 
hour, they returned by the same route reversed, the wind di- 
rectly opposing them; both of these days were very warm. 
During our progress up the Missouri river, I observed, several 
times, similar migrations of this species.

Inhabits the United States. 

Body with short hairs: head deeply indented on the front ; 
vertex with two small indentations: maxillary palpi with the 
three last joints dilated; the ultimate one triangular or cordate, 
being widely emarginate at tip ; the inner lobe somewhat mucro-

spine or seta as long as the joint placed on the exterior angle ; 
antepenultimate joint rounded, with a spine on the exterior side, 
similar and equal to that of the other joint: thorax rounded, 
somewhat angulated on the middle of the side, punctured : elytra 
not quite half the length of the abdomen; minutely punctured,

This species is not uncommon, and is often found under the 
loose bark of the yellow pine; it [98] is referrible to the genus 
Otenistes Reich. The elytra are terminated by a straight line 
like those of the dresdensis. It seems probable that the cordate, 
terminal joint of the maxillary palpi, and the two elongated 
spines of the preceding joints, may be peculiar to one sex, as a 
specimen in my collection has but a single spine, and the termi- 
nal joint is acute and not dilated.

testaceous: scutel with a lateral marginal line, the elevated a 
and two dorsal dilated lines, testaceous; the dorsal lines are 
merely emarginate on the inner side, and do not form the W; at 
the tip of each anterior line of the x is a conspicuous, black, im- 
pressed puncture, and behind the «x the posterior edge of the 
scutel is visible and testaceous: beneath, very pale testaceous ; 
rostrum black each side of the grooved base, in the middle 
and at tip: feet lineated with black ; anterior thighs bispinous: 
tergum with narrow posterior reddish-brown margins; termina] 
and anal segments testaceous, the latter with two black spots : 
nervures of the wings testaceous, beyond the middle fuscous. 

Length to the tip of the hemelytra less than one inch. 

Dr. James and Mr. Peale observed this species in great num- 
bers in one locality, at the base of [335] the Rocky Mountains: 
but it did not occur elsewhere.

an inch. 

A small species which I do not suppose to possess the power of 
yielding light, It inhabits the Arkanga near the Rocky Moun- 


tains.

his species is very closely allied to the S. auratus Meig. 
abr., but it is smaller, and the feet are dissimilar ; it may, how- 
sver, prove to be a variety of that species. 

2. §. porsatis.—Black, eyes brassy, with a green line; feet 
white, tibize and tarsi above blackish. 

-Inhabits Kentucky. 

- Stemmata approximate on the vertex; eyes brown, when re- 
sent brassy-green tinged with red or purplish, a broad, green, 
eitudinal line across the middle; antenne whitish at base; 
white; tarsi black at the tip; anterior and posterior tibiz 


‘ked by an oblong, opake, brown spot; abdomen oval, mid- 
of the two or three basal segments of the tergum and venter 


Length of 9 one-fifth of aninch, % rather less. 

‘The male is very similar to the female, but is a little smaller. 
This species is allied to the genus Vappo Latr., by the ner- 
ures of the wings, the nervure between the three which radiate 
‘om the central joint being altogether wanting, but the second 
yint of the antenne resembles that of a Sargus, the third joint

258 LONG'S SECOND EXPEDITION. 

Inhabits North-west Territory. 

Head pale yellowish; hypostoma slightly impressed with a 
black line, and another dilated black line descends [378] from 
the black vertex and includes the superior portion of the tuber- 
cle of the antennz ; mouth each side black; antennz blackish- 
piceous, basal joint and seta paler ; second joint decidedly longer 
than the first; eyes with two yellow bands of which the anterior 
one is irregular; occiput black, with a cinereous orbital line ; 
thorax with four yellow spots on the anterior margin; an obso- 
lete, yellowish, curved line above the wings terminating an- 
teriorly in a transverse, whitish spot on each side of the centre ; 
an angulated yellow line behind; pleura with two yellow spots 
placed vertically ; scutel edged with yellow ; wings hyaline, a fus- 
cous costal margin, ferruginous at base and gradually dilated to- 
wards the tip; poisers white; feet white; anterior pair with the 
anterior half of the thighs and tibiz and all the tarsi black ; in- 
termediate pair with the tip of the thighs, of the tibie, and all the 
tarsi pale rufous, posterior pair hairy beneath, with a tooth near 
the tip and posterior half black; tarsi and tip of the tibie pale 
rufous, the latter arcuated ; tergum with a band near the base, 
somewhat narrowest in its middle; another narrower one on the 
middle and two near the tip a little broader in their middles, 
yellow; venter with about three distant, narrow, yellow bands, 
of which the middle one is sometimes fulvous. 

Length less than three-fifths of an inch. 

This insect does not altogether agree with the characters of 
the genus in which I have placed it, inasmuch as the hind thighs 
are toothed, the hind tibiz arcuated, and the terminal joint of 
the antennz is oval and not elongated. It disagrees with Milesia 
in the elongated first and second joints of the antenne, and with 
Pipiza in the length of the palpi, and but for the character of 
the antenne, I should certainly refer it to the genus Milesia. 

[Macquart has placed this insect as a new genus Mixtemyia.

Descriptions of North American Curculionides and an arrangement of some 
of our known species agreeably to the method of Schoenherr,* July 1831. 


BRUCHUS Fabr. 


1. B. 4-macunatus, F. Oliv—Fabricius says it inhabits the 
island of Santa Cruz, and Olivier says it is from Carolina. The 
only individual I have seen was found by Mr. Barabino at New 
Orleans. 

Olivier gives its length at three-twentieths of an inch. The 
present specimen is considerably over one-tenth, but is less than 
three-twentieths. 


2. B. oprectus.—Dusky ; base and tip of the antenne feet 
and abdomen obscure rufous. 

Inhabits Louisiana. 

Body above blackish ; with prostrate, somewhat dense, dull 
yellowish hairs: antenne gradually thicker to the tip, basal half 
and terminal joint dull rufous, second joint nearly as long as the 
third : thorax with numerous, distant punctures; elytra immac- 
ulate, the striz distinct ; apical margin obsoletely rufous ; beneath 
black, with prostrate hair; feet dull rufous; posterior thighs 
somewhat dilated, beneath blackish with a tooth near the tip and 
about two small ones nearer the tip ; abdomen dull rufous, immae- 
ulate. 

Length less than three-twentieths of an inch. 


3. B. TRIANGULARIS.—Black ; elytra with a triangular band, 
in which is a black spot each side. 
Inhabits Mexico. 


*I am greatly ‘indebted to this distinguished naturalist for his able 
work the ‘‘ Dispositio Methodica Curculionidum”’ as well as for a know- 
ledge of several unpublished genera of this family ; my thanks are also 
due to Germar who has kindly furnished me with his ‘‘Coleopterorum 
species noye aut minus cognite descriptionibus illustrate,’’ in which 
many new genera are instituted. 

[The very unnatural classification of Schénherr has left this family 
in such an unsatisfactory condition so far as regards the identification 
of genera, that I have not yet attempted a critical study of our species. 
My notes on this paper therefore will be meagre and more imperfect 
than in other portions of the work.—LEc. ] 


260 CURCULIONIDES. 


Body black; antennz rufous at base; thorax transverse ; 
elytra with slender, deep, punctured strize; a common, large tri- 
angular white band, connected along the suture with the white 
scutel and attenuating to the lateral edge ; in the middle on each 
side of the suture is a black dot; posterior thighs with a spine, 
beyond which are two smaller spines. 

Length nearly three-twentieths of an inch. [2] 

Readily distinguished by the common white triangular band of 
the elytra marked by two black spots. I had three specimens 
from Mexican seeds of the size of those of Palmetto, but concave 
within. 


3. B. mrmus.—Brown, varied with black lines and cinereous. 

Inhabits Indiana. 

Body light brown, variegated: antenne pale rufous: thorax 
much narrowed before, with two interrupted, elevated, black lines 
and one or two on each side ; base rather prominent at the scutel ; 
scutel whitish apparently bifid: elytra with black spots and ab- 
breviated lines, which have a whitish spot at their anterior 
tip ; a light brown line curves inwards from the humerus and 
passes along the third interstitial line towards the tip; beneath 
dusky or blackish: feet pale rufous; posterior thighs blackish 
beneath with several minute spines and four or five larger ones 
near the tip: posterior tibiz blackish, subfasciate beyond the mid- 
dle : podex yellow.

5. B. ocunatus.—Brown; posterior thighs three or four- 
toothed. 

Inhabits Mexico. 

Body elongated, pale brown, covered on every part with short 
prostrate, dense hair: head on the front dusky, with a slight cu- 
preous tinge; much dilated orbits cinereous; tip of the labrum 
piceous : antennze fuscous : four basal joints honey-yellow; tho- 
rax with a hardly obvious, dorsal, pale line: elytra with aéute 
strie, which have distant punctures rather short: anal segment 
but little oblique, more than half the length of the elytra; feet 
honey-yellow : posterior thighs near the tip with about four teeth, 
of which the first is most prominent. 

Length one fifth of an inch. 


CURCULIONIDES. 261 


The anal segment is more nearly horizontal than any species I 
have seen. 


6. B. opsoLeTus.—Blackish, varied with cinereous hair. 

Inhabits Indiana. 

Body blackish cinereous, with a slight tinge of brown: anten- 
nz not deeply serrate: thorax much narrowed before, [ 3] cin- 
ereous each side, a slight impressed dorsal line; base with the 
edge almost angulated, central lobe almost truncate; scutel quad- 
rate, whitish, longitudinally divided by a dusky line; elytra with 
the interstitial lines having a slight appearance of alternating 
whitish and dusky ; on the middle of the third interstitial line is 
a more obvious abbreviated whitish line: posterior thighs with a 
black spine, and two smaller ones. 

Length over one-tenth of an inch. 

The whitish or cinereous markings are not very striking; on 
the elytra they may sometimes be traced into two obsolete macu- 
lar bands. I obtained many specimens from the seeds of an 
Astragulus in August, in company with Apion segnipes nob. 

7. B. mMuscuLus.—Blackish with cinereous hair; antenne and 
feet rufous. 

Inhabits Indiana. 

Body blackish-cinereous, with a slight tinge of brown, or black 
with cinereous hair: labrum piceous: antenne rufous at base 
and tip, piceous in the middle: thorax rather long, narrowed be- 
fore, somewhat cinereous each side, and on a dorsal line ; basal 
edge lobed at the scutel: scutel quadrate cinereous, with a dusky 
line ; elytra, third interstitial line with an abbreviated cinereous 
line on its middle; feet rufous; anterior thighs at base, interme- 
diate pair to the middle, black; posterior thighs with a spine, 
and three close set smaller ones distant from it, and with their 
tibize black. 

Length less than one-tenth of an inch. 

Resembles obsoletus nob., but is a little smaller, and the ru- 
fous antenne and feet distinguish it. 


8. B. rransversus.—Black, with cinereous hair; interstitial 
spaces with transverse black lines. 

Inhabits Indiana. 

Body black, more or less covered with cinereous hair; head 


‘

black: antennze rufous: thorax transverse, widely rounded before, 
with a scutellar lobe: scutel subquadrate with a dusky line: 
elytra, interstitial spaces interrupted by transverse black lines: 
feet rufous: posterior thighs black at base, armed with a spine 
near the tip. 

Length over one-tenth of an inch. 


ANTHRIBUS F. Sch. [4] 
Subgenus TRoprpEREs Sch. 


1. A. cornutus.—Thorax with five tubercles. 

Inhabits Indiana. 

Head white: mandibles piceous: antenne rufous, clava fuscous : 
rostrum moderate: eyes distant: thorax with two fascicles of 
erect hairs on the anterior edge, and three larger ones placed 
transversely on the middle; elytra somewhat variegated, with 
several fascicles of erect hairs on the interstitial lines; and a 
white, double, common, transverse spot before the middle; feet 
hairy. 

Length less than one-fifth of an inch. 

[This is A. coronatus Sch.—Lec. ] 


Subgenus PHAENITHON? Schon." 


2. A. BREVICORNIS.—Antenne short; seutel and alternate 
spots on the elytra, whitish. 

Inhabits Mexico. 

Body black-brown : head covered with prostrate whitish hair: 
antenne hardly longer than the head, fuseous; thorax with a 
transverse elevated subbasal line, rectilinear in the middle, ar- 
quated each side, reflected at the posterior angles, and termi- 
nating at the lateral middle: scutel white : elytra striated : inter- 
stitial spaces convex, with alternate blackish and whitish spots ; 
humerus prominent, and a prominence on the middle of the 
base: feet obscure piceous. 

Length less than three-twentieths of an inch. 

The tip of the club, exhibits the appearance of a fourth joint, 
which however is much smaller than the others; the eyes are 
emarginate. These characters justify the formation of a distinct 
subgenus.

RHYNCHITES Herbst. Schénh. 


1. R. copraris Fabr.—The three ultimate joints of the an- 
tennze are elongated, differing in this respect from the other spe- 
cies of the genus; it has been separated under the generic name 
of Sapindus. 

The species varies so much in color as to have given rise to 

‘several specific names, viz. : 

Anthribus collaris Fabr. Syst. Eleut. 

Rhynchites angustatus Herbst. [5] 

Rhynchites rubricollis nob., Journ. Acad. Nat. Sci,* and Melsh. 
Catal. 

Rhynchites nigripes Melsh. ; quercus Knoch. in Melsh. Catal. 

Rhynchites ruficollis Germar, Sp. Nov. p. 188. 

The latter is very remarkable in having the thorax of the same 
color as the elytra. Dejean in his Catalogue places the species 
in the genus Rhinomacer. 

[Is Hugnamptus angustatus Sch.—L«xc. | 


2. R. nirtus Fabr. 

R. xneus ? Bohemann. 

Doubts have been expressed of our insect being the hirtus of 
Fabr., but it agrees better with the description than any. It is 
also, as Fabricius says, of the stature and magnitude of R. pubes- 
cens. 


3. R. 2RATuS.—Brassy, antennee, rostrum, and beneath, ob-

neath blackish-blue. 

Length nearly one-tenth of an inch. 

This is the smallest North American species yet known. 

I have found it on the oak in June. 


Genus PTEROCOLUS Sch. 


Antenne 11-jointed, not geniculate; basal joint not much 
elongated ; eighth joint transverse linear ; ninth and tenth trans- 
verse subquadrate, dilated, and with the ultimate semioval one 
remote, perfoliated, forming an oblong oval club; rostrum di- 
lated at tip: head rather long behind the eyes, neck not con- ~ 
tracted ; scutel transverse subquadrate: elytra somewhat abbre- 
viated ; each rounded at tip, depressed above: podex and part of 
the back, naked: feet robust: thighs unarmed, dilated ; tibize un- 
armed, ciliate densely on the exterior edge with very short spines, 
and with small spines around the edge of the tip: body rounded. 

This genus differs from Rhynchites by the rounded form of 
the body; the shorter and depressed elytra, more divaricate [ 6 ] 
at their tips; the rostrum is shorter and more contracted in the 
middle, and the origin of the antennz is nearer the middle or 
rather the base of the rostrum; the tibie are ciliated with short 
spines, Xe.

LAIMOSACCUS Sch. 


L. practarus Fabr. Schénh. ; Curculio nephele Herbst. 

This is a well marked insect, remarkable by the very large

elytra with the striz rather wide and deep, punctured ; thighs 
with a tooth beneath. 

Inhabits Pennsylvania. 

Length to the tip of the rostrum three-tenths of an inch.

Genus THECESTERNUS nob. 


Anterior part of the pectus excavated for the reception of the 
rostrum. 

Natural character—Body convex, firm, unequal: rostrum 
very short, thick, entire: antennz rather slender, inserted near 
the middle of the rostrum, ina deep, somewhat angulated groove ; 
first jomt oblong turbinate, a little arquated; second and third 
short, subturbinate, the latter shorter; fourth and eighth very 
short, quadrate or transverse ; club rather large, of which the 
basal joint (or two joints 7) is as long again as the ultimate one, 
which is subacute: eyes a little oblique, somewhat acute before, 
oblong subovate: thorax longitudinally somewhat quadrate : scu- 
tel none: elytra connate, rigid, hardly broader at base than the 
thorax, narrowed at tip and concealing the podex: pectus ante-

This is our very abundant “ Fire-fly,” and is familiar to every 
inhabitant of this country. It is very like the centrata nob., 
but is much smaller and of a much paler color. With the late 
Mr. Melsheimer, [ have always hitherto considered this species 
to be the [165] pyralis of authors; but on a careful comparison 
with their descriptions, and particularly that of Olivier and his 
figure, I have, after much hesitation, concluded that it is dis- 
tinct from that species. The pyratis is described to be equal in 
size to the splendidula and noctiluca, but our species is smaller ; 
my chief reliance, however, is on the figure given by Olivier, 
which is beyond all doubt that of a widely different species from 
the present. 

The female differs from the male in having the elytra imper- 
fect, being not more than one-third the length of the abdomen ; 
they are, however, margined like those of the male.

It is also very destructive to Iris root of the shops, and to various 
other farinaceous substances. It has some resemblance to the A. 
striatum Fabr., of Europe, but the terminal joints of the antennz 
are less elongated, the thorax is less contracted before, and the 
strie of the elytra are much narrower. The name given by Mr. 
Melsheimer is pre-occupied. [174] 


TILLUS Fabr. Latr. 


1. T. prcotor.—Black ; thorax rufous, anterior and posterior 
margins black. 

Body hairy: head black : antennz dusky, pale rufous at base : 
mouth pale rufous: thorax contracted behind the middle, and a 
little dilated at the middle: rufous, anterior and posterior mar- 
gins black : elytra black, with regular strize of punctures: pectus 
tufous, anterior and posterior margins black : postpectus piceous : 
feet yellowish, knees and tarsi dusky. 

Length more than three-tenths of an inch. 

Resembles 7. elongatus Linn., of Europe, but the middle of the 
pectus is not black, and the anterior and posterior margins of the 
thorax are black. Mr. Nuttall brought me a specimen of this 
insect from Arkansa, and Dr. J. F. Melsheimer sent me one 
under the name which I have adopted. 

[This is a Cymatodera.—Lxc. } 


2. T. uNDULATUS.—Elytra pale testaceous, two undulated 
bands and tip black. 

Notoxus undulatus Melsh. Catal. 

Body long, slender: head black : eyes nearly entire : antennze 
pale rufous, nearly filiform, slightly larger towards the tip, and 
hardly serrated: palpi pale rufous: thorax blackish, cylindrical, 
transversely indented on the anterior submargin, a little dilated 
on the middle of the lateral margin, and narrower behind: elytra 
with regular strie of punctures, pale testaceous; basal margin 
blackish ; an undulated band before the middle, another behind, 
the middle and tip black: [175] beneath rufous, stethidium 
sometimes varied with blackish: feet pale testaceous; nails pec- 
tinated. ‘ 

Length nearly two-fifths of an inch. 

This insect has the habit of a Notoxus, but it cannot be con- 

(Vol. V.

generic with the mollis, owing to the conformation of the first 
joint of the tarsi, which agrees with that of the present genus. 
The antenne are much less serrated than those of elongatus Fabr., 
and are proportionally longer, the nails also are pectinated.

CLERUS Fabr. Dej. 


1. C. TRIFASCIATUS.—Rufous; elytra with a broad band on the 
middle, and tip black, an intermediate cinereous band. 

Body hairy, bright rufous : head at tip dusky : antennz black, 
terminal joint rufous at tip: thorax short, the transverse inden- 
tation rather deep: elytra rufous and granulated at base; on the 
middle a much dilated deep black band, undulated on its anterior 
and posterior edges, and with a narrow cinereous line at its ante- 
rior edge; behind this black band is a pale rufous band so covered 
by cinereous hair as to appear entirely cinereous ; tip deep black : 
beneath rufous: feet hairy, black. 

- Length more than nine-twentieths of an inch. 

This insect has considerable resemblance to the ichnewmoneus 
Fabr., and rufus Oliv., but the black band occupies the situation 
of the rufous band of those insects, behind this band these two 
species have [176] a black band, but in our insect this is rufo- 
cinereous; the tip also is deep black, whereas in the above men- 
tioned species, it is either spotted or margined with cinereous.

ate with black. 

Body greenish-black : antenne and palpi pale rufous, terminal 
joint of the former a little dusky : thorax widest before the mid- 
dle, contracted behind; an indented transverse line on the ante- 
rior submargin, and a less conspicuous one on the posterior 
margin: elytra very pale testaceous, with a black band on the 
middle, and another at tip: feet pale testaceous, posterior pair 
rather long.

ENOPLIUM Latr. 


E. pistocatuM.—Black ; elytra with a whitish band and 
spots. 

Body punctured, black, hairy: head on the anterior [177 ] 
part reddish-yellow ; antennz brownish, yellowish at base, ter- 
minal joints not deeply serrated, somewhat rounded: thorax sub- 
cylindric: elytra with an oblique line from the humerus, having 
a spot at its inner tip,an angulated band beyond the middle, and 
a spot near the tip, whitish-yellow : feet pale. 

Length from three-twentieths to nearly one-fifth of an inch. 

Var. a. Spot at tip of the elytra obsolete or wanting. 

Although the antenne differ considerably from the character- 
istic form of this genus, yet as they have three large and sepa- 
rated joints at tip, and*the palpi are all filiform, with five distinet 
joints to the tarsi, I have thought best to place the present in- 
sect in the genus Hnoplium. \

NECROPHORUS Fabr. 


N. orprcouiiis.—Thorax orbicular: elytra with rufous band 
before the middle and spot at tip. 

Body deep black, above polished: clypeus before with a large, 
square, rufous spot: antenne black ; clavum, excepting its first 
joint, light ferruginous : thorax orbicular, margined all round, ex- 
cepting on the anterior portion, which is truncated ; the impressed 
lines are well defined, and the longitudinal one extends to the 
base undiminished: elytra minutely punctured, and with two

obsolete neryures ; the anterior band is rather before the middle, 
but does not extend to the seutel; it is undulated, and does not 
reach the suture ; the spot at tip is somewhat [178] reniform or 
trilobate, and does not reach the edge or suture: beneath pi- 
ceous : feet above black : postpectus yellow sericeous. 

Length more than nine-tenths of an inch. 

It differs from marginatus Fabr., particularly in the rounded 
form of the thorax, which in that species is much narrowed be- 
hind: the elytra of marginatus have a rufous exterior margin, 
the basal band is not interrupted by the suture, and embraces 
the tip of the scutel; there is also a band at tip. The colors of 
the antenne are arranged exactly as in vespillo Fabr., but the 
thorax is much more accurately rounded, and the elytral mark- 
ings are different. The rotundity of the thorax is more com- 
plete than even that of mortuorum Fabr. The species occurs in 
the N. W. Territory: it is very rare in the Middle States. I 
have received a specimen from Dr. T. W. Harris of Milton, 
Massachusetts. 


NITIDULA Fabr. Dej. 


I. N. 6-MacuLata.—Blackish, with a broad pale rufous mar- 
gin and elytral spots. 

Nitidula 6-maculata Melsh. Catal. 

Body blackish-brown or deep piceous: antennz pale rufous: 
thorax with a dilated pale rufous margin: elytra with a dilated 
pale rufous margin; an angulated line in the form of a U at 
base, a small spot on the submargin, sometimes connected with a 
line which runs towards the tip, and becomes confluent with the 
lateral margin ; an angulated or rounded spot [179] behind the 
middle, rufous : beneath piceous: feet paler. 

Length more than a quarter of an inch. 

The rufous angular line at the base of each elytron, in the 
form of the letter U, is a striking character.

2. N. z1czAc.—Black-brown ; elytra with an angulated band. 
Body dark-brown or blackish, with numerous prostrate hairs : 
antennz piceous, two basal joints rufous: thorax with a rufo- 
cinereous lateral margin : elytra without striz, an obsoletely rufo- 
cinereous margin ; on each is one or two obsolete rufous spots at

base, and a very obvious ochreous spot on the middle, in the 
form of a V, the angle pointing towards the base: beneath black- 
ish-piceous : feet and lateral margin of the pectus, rufous. 

Length more than three-twentieths of an inch. 

This species was sent me by Dr. J. F. Melsheimer, who re- 
marked, that “it resembles the European Mitidula undulata 
very much, but differs in having the undula or lunule nearer to 
the apex of the elytra.” With that species I am entirely unac- 
quainted. 

3. N. unpuLATA.—Yellowish-fulvous, varied with fuscous ; 
an undulated, common immaculate space behind the middle of 
the elytra. 

Nitidula undulata Melsh. Catal. 

Body above fulvous, more or less tinged with yellowish : head 
varied with fuscous, sometimes nearly all fuscous, with the ex- 
ception of the anterior portion, [180] and the antenne: thorax 
literate with fuscous, the broad lateral margins immaculate with 
the exception of a single spot on the middle: elytra irregularly 
marked with small fuscous spots; a large, common, transverse, 
undulated, immaculate space behind the middle : slightly striated ; 
striz not obviously punctured, but furnished with very short, 
recurved hairs; exterior margin immaculate: beneath rufous: 
feet and tail paler. 

Length about one-fifth of an inch. 

The European analogue of this insect is certainly the NV. varia 
Fabr., but the spots of the elytra of that insect seem to be more 
distinctly arranged in abbreviated longitudinal lines, and the 
common immaculate space of the elytra appears to be less ob- 
vious, and less acutely undulated. I know of no species in this 
country, for which it. can be readily mistaken. It may possi- 
bly prove to be a variety of varia.

5. N. GEMINATA.—Reddish-brown: elytra, each with four 
ochreous spots, placed 2, 2. 

Body obscure reddish-brown, a little hairy: thorax widest at 
the basal angles; lateral margin rufous: elytra striate with ele- 
vated, acute lines, and with intervening regularly concave 
grooves ; tip reunded, concealing the extremity of the abdomen ; 
on each elytrum are four ochreous spots, of which one is on the 
humerus: another near the scutel, elongated, approaching the 
suture, near the tip, and sometimes common; and two other 
rounded ones beyond the middle, placed transversely, equal; ex- 
terior margin obscure ochreous. 

Length more than one-tenth of an inch. 

The general color of the elytra is sometimes so similar to that 
of the spots, that the latter are hardly observable. 

[Belongs to Stelidota Kr.—Lxc.] 


6. N. 8-MacuLtata.—Dark reddish-brown: elytra with four 
rufous spots placed 1, 2, 1. 

Body very obscure reddish-brown : front with two indentations : 
thorax rather large; lateral margin paler; elytra striate with 
slightly elevated lines ; a rufous oblong spot at the middle of the 

base, a rounded one behind the humerus, atiother on the sutural 
. margin near the middle, and a fourth a little behind the mid- 
dle, oval, oblique; tip rounded, concealing the tip of the abdo- 
men, and rufous. 

Length more than one-tenth of an inch. 

The lines of the elytra are more obtuse than those [ 182 ] of the 
preceding species, the interstitial spaces are not so regularly 
grooved, and the spots are located differently. I found it in 
plenty, when on the Arkansa river with Major Long’s party.

tinguished by the vitta of the elytra, and the much less pro- 
foundly emarginated clypeus. 


TROX Fabr. 


1. T. strraTuLus.—Elytra with elevated acute lines, and in- 
termediate regular grooves. 

Trox striatulus Melsh. Catal. 

Head blackish-brown, with confluent punctures; tip widely 
emarginate : thorax blackish-brown, with dilated confluent punc- 
tures ; a slightly impressed longitudinal groove ; sides very much 
decurved : elytra light brown, with numerous profound grooves, 
which are separated by elevated acute lines. 

Length three-twentieths of an inch. 

The smallest species known to inhabit the United States, and 
so perfectly distinct in the striking character of its grooved ely- 
tra, as not to require any comparative observations. 


2. T. TERRESTRIS.—Elytra with raised obtuse lines, on which 
are round fascicles of short hairs. 

Trox terrestris Melsh. Catal. 

Body blackish-brown: head with two small tubercles on the 
front: thorax with the dorsal groove very distinct, contracted 
and almost obliterated in its middle, so as to be nearly inter- 
rupted into two, on each [193] side of the posterior portion of 
1825.] 


296 ACADEMY OF NATURAL SCIENCES 


it is another groove equally profound ; posterior angles obliquely 
truncated: elytra with the fascicles of yellow hair, on the ele- 
vated lines, rounded and not oblong, equal; interstitial spaces 
with small tubercles. 

Length nearly one-fourth of an inch. 

This insect is about equal in size to the arenarius Fabr., from 
which it differs in having no capillary lines in the interstitial 
spaces of the elytra. The variolatus of Melsh. Catal. if not alto- 
gether the same as the arenarius of Europe, is certainly most 
closely allied to it. 


3. T. porcatus.—Elytra with elevated interrupted lines and 
numerous transverse punctures on the interstitial spaces. 

Trox porcatus Melsh. Catal. 

Body brownish-black: head somewhat inequal, with a more 
distinct frontal groove: thorax with short brownish hair ; a deep 
and well defined longitudinal groove, sides inequal ; lateral edge 
entire ; posterior angles projecting: elytra with regular series of 
interrupted hairy lines, the series alternately smaller ; interstitial 
spaces with dilated transverse impressed distinet punctures. 

Length nearly nine-twentieths of an inch. 

A little larger than canaliculatus nobis, which it resembles, 
but it differs in having the transverse punctures of the elytra ; 
capillaris nobis is smaller than the above-mentioned species, and 
may be distinguished from the present by the capillary lines of 
its elytra. [194] 

SCARAB AUS Latr. 


S. reLicrus.—Head with an elevated transverse line, inter- 
rupted in the middle ; clypeus at tip elevated and bidentate. 
Body brownish-black: head with a transverse elevated line 
between the origin of the antennee, interrupted in the middle, 
and most prominent near the interrupted part; tip of the clypeus 
with two reflected, acute denticulations: thorax with rather 
sparse punctures : elytra punctured, and with three double series 
of punctures, converging towards the apical angle; the second 
and third double series do not reach the angle, a fourth double 
series is on the exterior submargin, but is not so distinct as the 
others: beneath piceous: pectus and postpectus hairy: feet 
above blackish : yenter blackish. 
[Vole V. 


OF PHILADELPHIA. 297 


Length more than four-fifths of an inch. 

It may be compared with the S. punctatus Fabr. of Southern 
Kurope, but is of a more slender form, and is otherwise dis- 
tinguished by the armature of the anterior termination of the 
head. I have found specimens in Pennsylvania. It varies in 
having the reflected tip of the head emarginate, and not deeply 
divided into two teeth. I have received a specimen from Dr. 'T. 
W. Harris, of Milton, Massachusetts. 

[Belongs to Ligyrus Burm.—L«c. ] 


MELOLONTHA Fabr. 


1. M. satra.—Chesnut-brown; head and thorax blackish- 
brown; the former and the inferior surface of the stethidium 
hairy. [195] 

Body cylindrical; head blackish, with small but dense and 
confluent punctures; front, below the vertex, and above the trans- 
verse impressed line, with a band of rather long dense ochreous 
hairs, terminating at the eyes ; clypeus deeply and widely emargi- 
nated, the edge reflected, and beneath the edge is a fringe of re- 
curved hairs; thorax rather prominent on the middle of the 
lateral edge; nearly as dark colored as the head; punctures 
numerous, irregularly disposed: scutel with a few punctures, 
and with reflected prostrate yellow hairs at its base, partly 
covered by the base of the thorax: elytra confluently punctured, 
chestnut-brown: stethidium beneath, with dense pale yellow hair : 
nails with a prominent tooth on the middle, and an angle at 
base. 

Var. a. Thorax rufo-castaneous. 

Length more than thirteen-twentieths of an inch. 

This common species was sent to me by Dr. J. F. Melsheimer, 
under the name which I have adopted. The following are his 
remarks: “it differs from J. quercina in being more cylindrical, 
from M. quercus, in the absence of the “rore ccerulescenti,” Xe. 
and from M. hirticula, in the want of the triple series of fuscous 
erect hair on each elytrum. In its proper season this insect may 
be found in vast numbers under the deciduous leaves of forests ; 
during the night the millions of wings that fan the air, produce 
a loud humming sound, not unlike that emitted by the enraged 


occupants of a humble-bee’s nest.” 
1825.] 


298 ACADEMY OF NATURAL SCIENCES 


It is much smaller than the quercina, smaller than the hirticu- 
la, and larger than quercus. 


[Belongs to Lachnosterna.—Lxc.] [196] 


2. M. Epui~ipa.—Ochraceous; thorax somewhat rufous ; 
head blackish ; clypeus nearly entire. 

Head blackish, with sometimes an obscure chestnut disk ; very 
densely and confluently punctured; punctures small: clypeus, 
anterior termination widely, but slightly truncated, not at all 
emarginated, the edge reflected: thorax pale rufo-castaneous, 
polished ; punctures irregularly scattered ; middle of the lateral 
edge rather prominent: scutel with a very few punctures, and 
with reflected prostrate hairs at its base, partly covered by the 
base of the thorax: elytra pale ochraceous, densely punctured : 
stethidium beneath, with pale yellow, dense hair: nails with a 
strong prominent tooth on the middle. 

Var. a. Scutel entirely destitute of punctures. 

Length three-fifths of an inch. 

This species closely resembles the preceding, but it has a 
more robust form, it is somewhat shorter, destitute of the frontal 
band of hair, and is of a paler color. I adopt the name given 
to it by Dr. J. F. Melsheimer, who remarked ina letter to me, 
that “it approaches nearest to a Melolontha described by Pro- 
fessor Knoch under the name of angularis, but as the thoracic 
angles of that insect are covered with a substance resembling 
Mother of Pearl, or, as the Professor expresses it, “einer farbe 
die véllig mit der kalkerde iiberein kimmt; welche von den 
Mineralogen Schaumerde genannt wird,’ we cannot connect 
with propriety, our insect with the M. angularis.’ In color it 
closely resembles the longitarsa nobis (in Long’s second expedi- 
tion) but that [197] insect is somewhat smaller, with an emargi- 
nate clypeus and much longer-tarsi. 

[Belongs to Lachnosterna ; Burmeister places it in Trichestes, 
which is not entitled to be considered as a’ genus. —Lec.] 


3. M. Morsta.—Elytra punctured, and with two double series 
of punctures ; clypeus slightly emarginated. 
Melolontha moesta Knoch in Melsh. Catal. 
Head with very ‘dense profound punctures; transverse line be- 
tween the eyes rather deeply.indented : clypeus with the margin 
[Vol. V. 


OF PHILADELPHIA. 299 


recurved, the tip very obtusely, but not very profoundly emargi- 
nated: thorax with scattered profound punctures; lateral edge 
obtusely projecting a little, rather behind its middle: elytra with 
numerous punctures, and with two regular double series of punc- 
tures on the disk, one or two on the exterior submargin, and a 
single subsutural series: beneath glabrous: nails with a robust 
prominent obliquely truncated tooth beyond the middle. 

Length about one-half an inch. 

The color of young specimens is rather pale chestnut, but, as is 
the fact with respect to many species, as they grow older, the color 
becomes darker, and it is not uncommon to find individuals that 
are almost black. 

[A species of Diplotaxis, previously described as MM. liberta 
Germ.—LEc. ] 


4, M. sorpipa.—Covered with short dense hair. 

Melolontha sordida Melsh. Catal. 

Superior surface entirely covered by short close set hairs, which 
are longest on the head, thorax, and base of the elytra; the punc- 
tures are also dense and confluent: clypeus with the edge reflect- 
ed; tip widely emarginated: thorax, lateral edge reflected, and 
[198] a little dilated rather behind the middle: elytra having the 
subsutural line obliterated: beneath nearly glabrous: nails with 
an obliquely truncated, very robust tooth beyond the middle. 

Length about two-fifths of an inch. 

The color varies considerably. I have a specimen that is of a 
pale chestnut color, and others that are dark dullbrown. I have 
found this species in May; and at Chinquoteague Island, many in- 
dividuals occurred under yellow.pine trees in company with the 
preceding species in October. It is very well distinguished from 
other species by its equally distributed hairy covering. 

[Belongs to Diplotaxis, and afterwards described as D. carbo- 
naria Burm.—LeEc.] 


5. M. rronpicota.—Elytra punctured, and with two double 
series of punctures ; ¢lypeus entire. 

Melolontha frondicola Knoch, Melsh. Catal. 

Body pale chesnut : head ‘dusky, with large confluent. punc- 
tures ; transverse line’ ‘angulated i in the middle; clypeus very ob- 
bse rounded at tip, almost truncated, the edge reflected : see) 


1826.) 


300 ACADEMY OF NATURAL SCIENCES 


with rather large, very numerous punctures, more dense and con- 
fluent on the sides; lateral edge a little obtusely dilated at the 
middle: elytra with numerous punctures, and with two double 
strie of punctures on the disk, one or two on the exterior sub- 
margin, and a single subsutural one : beneath glabrous : nails with 
a remarkably robust broad compressed truncated tooth. 

Length three-tenths of an inch. 

Although this species is very similar in some respect to the 
moesta, yet it is so much smaller as to [199] be readily distin- 
cuished ; the clypeus also of that species is emarginated, and the 
punctured series are much more regular than those of the present 
species, in which the punctures of the series are often confluent 
with the punctures of the interstitial lines. As regards, size, it is 
but little smaller than vespertina, which has numerous indented 
strize on the elytra. 

[ Also a Diplotaxis and appears to be D. testacea Burm.—LEc. ] 


6. M. unirascrata.—Thorax very dark green; elytra testa- 
ceous, with a black abbreviated band or spot on the middle. 

Head densely punctured, particularly before, very dark green- 
ish on the vertex, and tinged with cupreous before: clypeus en- 
tire at tip, the edge reflected: thorax blackish-green, rather 
sparsely punctured, punctures small, lateral edge a little dilated 
rather before the middle: scutel dark green, sometimes tinged 
with cupreous, with a few punctures : elytra pale testaceous, in a 
particular light having a slight metallic tinge, each with seven 
or eight regular striz of punctures, and a few scattered ones 
near the suture; margin and suture dusky; on the middle is a 
blackish band which is more or less interrupted or undulated : 
beneath black, slightly tinged with green and cupreous: stethi- 
dium a little hairy: acetabulum with an indented longitudinal 
line : nails, of the anterior and intermediate feet having one nail 
simple, and the other bifid at tip, of the posterior feet simple. 

Length two-fifths of an inch. 

Var. a. Elytra, excepting at base, simple. 

This species is very closely allied to varians Fabr., but it may 
be distinguished by its much larger size. [200] The varians 
is not uncommon in Pennsylvania, but the present is a Southern 
species. Dr. J. F. Melsheimer gave it the name of vernalis, 


[Vol. V. 


OF PHILADELPHIA. 301 


which is preoccupied in this genus; he informed me that it 
“‘was captured in Virginia, in the early part of the year 1807. 
Male and female were flying about in a ploughed field in innu- 
merable multitudes.” 

Judging from its habit, it belongs to Megerle’s genus Ano- 
mala. 

[An Anomadla previously described as M. binotata Schénh— 
Lec.] 

HOPLIA Nig. 

H. Trirascrata.—Head black : clypeus at tip reflected: tho- 
rax densely covered with reddish-yellow scales: feet brownish- 
red: scutel blackish: elytra light brownish-red, with sparse yel- 
lowish scales, which, however, are more dense in some parts, so 
as to form three bands, which are tolerably distinct; of these, 
one is at the base, the other on the middle, and the third near 
the tip ; they are somewhat undulated : anal segment and beneath 
densely covered with pale cinereous scales, which have, in some 
parts, a cupreous reflection. The opposite sex is black on those 
parts, which in the other are brownish-red, and the bands of the 
elytra are hardly discernible: in both sexes the humerus is pro- 
minent, and at the decurvature of the elytra near the tip, they 
are elevated almost into an angle. 

Length nearly one-third of an inch. 

The great difference in color between the two sexes of this 
species, may readily deceive naturalists into the belief that they 
are two distinct species. [201 ] 

[Described by Burmeister as H. primona; the male also by 
Melsheimer as /. tristis—Leo.] 


CETONIA Fabr. 

C. vesTita.—Hairy ; clypeus emarginate ; elytra with a few 
white spots. 

Body brownish-black, with very numerous, rather long, re- 
flected, cinereous hairs: head with the hairs smaller and sparse 
before ; clypeus widely emarginate at tip, the lateral angles sub- 
acute and a little elevated; lateral margin not recurved: thorax 
with a carinated glabrous line, little elevated but very distinct : 


elytra with two hardly obvious elevated lines on the middle, con- 
1825.] . 


302 ACADEMY OF NATURAL SCIENCES 


fluent behind; striz slightly impressed, with small punctures ; 
on each elytrum is a small white dot on the middle of the sutural 
submargin, another behind the middle and approaching nearer 
to the suture, three oblique ones on the exterior submargin, and 
a transverse one at tip near the suture. 

Length two-fifths of an inch. 

This species resembles the sepulchralis Fabr., but it differs in 
having the clypeus emarginated, the hairs of the body elongated, 
and the spots of the elytra fewer in number. In form it is more 
slender than that well known species, and its color more opaque 
and less metallic. It is much more closely allied to the C. hirta 
Fabr., of Europe, the spots being nearly similar; but the vestita 
is one half smaller, and the hair is much coarser and much less 
abundant ; can it be a variety of that species ? 

I have met with but two specimens, one beloning to the Phila- 
delphia Museum, and the other sent to me by Dr. T. W. Harris, 
of Milton, Massachusetts. [202] 

[Unknown to me; believed by Schaum and other entomolo- 
gists to be the European species.—LEc. ] 


LUCANUS Linn. Latr. 


1. L. pracipus.—Head small, slightly concave ;, tooth of the 
mandibles emarginate. 

Body dark reddish-brown: head slightly concaye, rather nar- 
rower than the thorax: mandibles hardly as long as the head, 
regularly curved ; tooth a little beyond the middle, not very pro- 
minent, but rather wide and emarginate at tip: elytra without 
strive : anterior tibize about four-toothed, superior tooth small. 

Length one inch. 

I found this species when with Major Long’s party in Arkansa. 
It differs from the dama Fabr. in being smaller, in having the 
head narrower than the thorax, the mandibles shorter and less 
arcuated, and their tooth wide and bifid at its tip. 

[Appears to be the female of L. ldentus, a species cited from 
Say, but of which, as Burmeister observes, no description can be 
found in his writings; it was first published under that name by 
Laporte, in his Hist. Nat. 2,71. The name placidus has greatly 
the priority.—LEc. ] 

[Vol. V. 


OF PHILADELPHIA. 303 


2. L. BREVIS.—Short and wide; mandibles one-toothed; ely- 
tra smooth, humerus mucronate. 

Body robust, reddish-brown: head wide, rather narrower than 
the thorax, minutely punctured, a little concave above the man- 
dibles ; mandibles short, with one simple oblique tooth on the mid- 
dle, extending inwards and forwards; thorax wide with minute 
punctures, angles rounded ; posterior ones not obliquely truncated ; 
elytra nearly smooth, having numerous small punctures, and ob- 
solete, hardly impressed lines ; humerus mucronate: anterior ti- 
bie with five or six small denticulations, and a broad terminal, 
prominent one widely emarginate; intermediate tibiz with a 
single spine on the middle. [ 203 | 

Length nearly nine-tenths of an inch. 

This species seems to be related to parallelus nobis, but it is 
much wider in proportion to its length, and there are no distinct 
strize on the elytra.

1. T. REFLEXUS.—Blackish-green ; edge of the clypeus re- 
flected ; thorax subquadrate. 

Tenebrio xruginosus Melsh. Catal. 

Body very dark green, almost black: head minutely and 
densely punctured, anterior edge of the clypeus regularly ar- 
cuated and reflected; antennz black; palpi blackish piceous ; 
thorax rather transversely quadrate, minutely and densely punc- 
tured ; angles subacute: elytra with impressed, punctured strie ; 
interstitial lines depressed, almost flattened, obsoletely punc- 
tured: tibie, anterior pair of the male with a prominent angle 
above the middle, and with the second pair much arcuated on 
the inner side. 

Length three-fifths of an inch. 

The specific name xruginosus is preoccupied. 

[This belongs to Centronipus, and is 7. calcaratus Fabr.—Lec. ] 

2. 'T. RuFIPES.—Black, polished; terminal joint of the an- 
tenne pale fulyous; thighs bright rufous.

rather narrower than the elytra, and with the head densely and 
minutely punctured : elytra with impressed, punctured striae, and 
convex interstitial lines: thighs bright rufous; tibiz, anterior 
[ 204] pair of the male with a short spine on the inner middle. 

Length half an inch. 

I have stated this insect to be polished, in order to distinguish 
it from the Upis fulvipes Herbst, which it very much resembles, 
and with which it is strictly congeneric. 

[Also a Centronipus.—Lec.]

OPATRUM Fabr. 


1. O. Notum.—Brownish-black : elytra with regular series of 
impressed punctures. 

Opatrum clathratum Melsh. Catal. 

Head with small, close set punctures ; terminal emargination 
not angulated: thorax with small, close set punctures ; lateral 
edge reflected ; posterior angles somewhat produced subacute : 
elytra destitute of impressed striz, but with regular series of 
large, profoundly impressed, rather longitudinal punctures ; tarsi 
piceous. 

Length less than seven-twentieths of an inch. 

This does not correspond with the description of the c/athra- 
tum Fabr., inasmuch as the elytra are not striated. It is common. 

[Belongs to Opatrinus.—L«Ec. ] 

2. O. PULLUM.—Brown; head and thorax darker; elytra 
with punctured striz ; beneath reddish-brown. 

Desc. Head and thorax dark-brown, minutely and densely 
punctured ; posterior angles not prominent; lateral edges not re- 
flected: antennze piceous ; terminal emarginations of the clypeus 
not angulated : elytra with impressed, punctured striz, the punc- 
tures profound, somewhat transverse; interstitial lines with 
numerous small punctures : beneath reddish-brown. (6,0 mm

the preceding by the striated elytra, and by the simple edge of 
the thorax. 

[Unknown to me, perhaps a Blapstinus.—LEc.] 


BOROS Herbst. 


B. unIcoLor.—Blackish-brown, punctured ; thorax not obvi- 
ously indented behind. 

Body depressed, rather slender, blackish-brown, punctured : 
head suboval, punctures rather large, numerous; smaller before ; 
a dilated indentation each side anterior to the eyes: antennze but 
little longer than the head: thorax oval, accurately rounded each 
side, punctures numerous, rather large; no indentation: elytra 
with irregular, numerous punctures, smaller than those of the 
thorax, not disposed in any regular series; an obtuse indented 
line on the outer margin, and another at the suture. 

Length nine-twentieths of an inch. 

I received this insect from Dr. J. F. Melsheimer, under the 
name I have adopted. It is certainly very closely allied to B. 
elongatus Herbst, but judging by the figure given by this author, 
it is much smaller; it is also destitute of any obvious indentation 
on the posterior part of the thorax. 

[On comparison I find the sides of the thorax to be a little 
more rounded than in the European specimens.—L&c. ]

behind ; brown, covered with very numerous, bright sericeous 
hairs: antenne and palpi rufous: thorax but little undulated on 
the posterior edge: elytra with slender, punctured strize : beneath 
color of the antenne.

color, almost black, with a comparatively slight opal-sericeous 
gloss; the antennz also are blackish, with the base and tip 
rufous or fulyous; the bifasciatus nob., has banded elytra. [240 ] 


HELOPS Fabr. 


1. H. putitus.—Body short, very convex, somewhat eupreous ; 
third joint of the antennz not greatly longer than the fourth. 

Helops pullus Melsh. Catal. 

Antenne piceous ; third joint hardly as long as the fourth and 
fifth together; the two latter equal: eyes moderate: head and 
thorax densely and equally punctured; anterior angles of the 
latter subacute ; lateral edge slightly contracted behind the an- 
terior angles: elytra rather paler than the head and thorax, and 
more obviously cupreous, with punctured striae : pectus each side, 
with numerous, longitudinal, impressed lines ; tarsi dark rufous. 

Length from one-fourth to three-tenths of an inch. 

In general form, it somewhat resembles H. contractus Beauy.; 
particularly in the great convexity of the superior surface of the 
body ; but it cannot be mistaken for that insect. 


2. H. porrrus.—Cupreous ; elytra united ; wings imperfect. 

Body bright copper, polished; punctured: antennz long, 
blackish ; third joint equal to the fourth and fifth together, 
which are equal; labrum piceous: eyes moderate: thorax de- 
cidedly widest before, narrowest at the posterior angles, with 
small, close set punctures, and a longitudinal, obsolete, impressed 
line: elytra united, the line of the suture distinct, with acutely 
impressed, punctured striz; interstitial lines flat, with very 
minute punctures: wings imperfect, shorter. than the elytra: 
beneath piceous. [241 ] 

Length two-fifths of an inch.

fulvous; thorax cylindrical. 

Body elongated, brownish black: eyes large : antennee rather 
short; fifth joint obviously shorter than the fourth; terminal

sub-cylindric, slightly wider in the middle, equally wide at base 
and tip; narrower than the elytra: elytra with rather wide and 
profound striz, which are punctured ; interstitial lines narrow, 
convex ; beneath piceous: anterior tibie slightly arcuated. 

Length half an inch. 

This species resembles a Upis, in the form of the thorax.

4, H. aratus.—Body short, moderately convex; third joint 
of the antennez rather shorter than the fourth and fifth united ; 
lateral thoracic edges rectilinear. 

Head punctured densely: antenne dark testaceous: thorax 
dull metallic greenish, slightly tinged with purplish; thickly 
punctured, punctures rather large; angles subacute; lateral 
rectilinear : elytra slightly purplish, brassy, with punctured striz, 
and smaller punctures on the intermeditae spaces: beneath 
blackish : pectus punctured on each side, with small, close set, 
longitudinal impressed lines: feet reddish-testaceous at base. 

Length one-fourth of an inch. [ 242] 

I am indebted for this species to Mr. Jno. S. Skinner, editor 
of the American Farmer, who received it from a correspondent, 
with a note, stating that they had been found on the body of the 
peach tree, just below the surface of the ground.

angles subacutely rounded: elytra with slightly impressed _striz, 
their punctures profound: beneath piceous, and, excepting the

Length % lessthan one-fourth ; ? more than three-tenths of an 
inch.

308 ACADEMY OF NATURAL SCIENCES 


The male in my specimens is of a paler color than the female. 
It differs from the atra nob., by having the striz of the elytra 
much less deeply impressed. 

The palpi are all terminated by a joint formed like a reversed 
triangle ; it therefore belongs more properly to the genus Ad/e- 
cula of authors. 

2. CO. arra:—Blackish-brown, with short hairs; striz of the 
elytra deeply impressed. 

Cistela atra Melsh. Catal, [243] 

Body nearly black, with a tinge of brown, with numerous short 
blackish hairs, arising from punctures : head transversely indented 
between the eyes; antennz dark fuscous, nearly half as long as 
the body, terminal joints somewhat ovate, and slightly petiolated : 
thorax with the posterior angles subacutely rounded: elytra 
with rather deeply impressed, punctured striz: beneath dark 
rufo-piceous. 

Length three-tenths of an inch. 

It may be distinguished from the preceding, by the form of 
the terminal joints of the antenna, as well as by the more deeply 
impressed striz. 

[The name having been previously employed, this species has 
been described by Dr. Melsheimer as Alleculu nigrans.—LEc. }

in having the elytra banded, the base of these wing-sheaths is 
not turgid, as in that species. I obtained a specimen in East — 
Florida, when in that country with Mr. Maclure’s party. 

[The name being preoccupied, this was afterwards named by 
Ferte A. bizonatus; it does not, however, appear different from 
his A. cervinus.—Lk«c. ]

transverse impressed line and spot at base : scutel rounded at tip: 
elytra densely punctured, tip mucronate, and with an indented 
spot: coxee and trochanters rufous: pectus rufous, a lateral, sub- 
marginal black spot. 

Length about seven-twentieths of an inch. [ 248 } 

Taken on the lower Missouri, near Fort Osage: closely allied 
to the preceding species. 

[ Afterwards described as Pyrochroa infumata Hentz, and Ped. 
marginicollis LZiegler.—L«xc. ] 

9. A. ImprEssus.—Black: thorax rufous; an indented spot 
at the tip of each elytra. 

Inhabits Pennsylvania. 

Mouth, antennze, two basal joints, and palpi at base, dark rufous : 
thorax rufous, with a longitudinal slightly impressed line : elytra 
densely and irregularly punctured ; a large profound, indented, 
oval impunctured spot at the sutural tip of each elytra. 

Length three-tenths of an inch. 

Resembles A. collaris, but is distinguished by its somewhat 
larger size, and the profoundly impressed spot at the tip of each 
elytra. I found this species early in May, attached to the side 
of a Meloe angusticollis, which was perfectly at rest upon the 
ground, not appearing to be in the slightest degree incommoded 
by the weight of its temporary parasite, but seeming rather 
pleased with its society. This species and the ugubris, collaris, 
terminalis, and labiatus, differ much from the other species of the 
genus that have come under my observation; but as they appear 
to me to approach more closely to this genus than to any other, 
I place them here for the present.

[Belongs to Brachytarsus.—LEc’] 

5. A. ALTERNATUS.—Robust ; elytra with series of alternate 
gray and black spot. 

Body short and thick, densely hairy, brownish-cinereous : head 
plane, not prominent between the eyes: antennz moderate, pale 
rufous, three last joints fuscous: thorax with a few black spots ; 
elevated line of the posterior margin not prominent, placed near, 
and parallel to the posterior edge: elytra with punctured [251 ] 
strie, alternate interstitial lines, with alternate black and gray 
spots: feet rufous; thighs dusky ; tibiz with about two dusky 
bands. 

Length three-twentieths of an inch. 

This may readily be distinguished from A. capitlicornis, by the 
much shorter antennz, and more robust form of body. 

[Also a Brachytarsus.—LEc. ] 


6.. A. VARIEGATUS.—Varied, with blackish and dull yellow- 
ish; elytra, each with two larger spots.

middle, near the suture: feet pale rufous: thighs blackish in the 
middle. 

Length more than one-tenth of an inch. 

The two spots of eaeh elytron are sometimes united by an 
intervening blackish sutural line. 

The species is not uncommon, and I have found it on the 
“smut” of wheat. Mr. Lea took eighty individuals from six 
heads of wheat. 

[Subsequently described by Schénherr as Brachytarsus obso- 
letus. —Lxc. ]

1. A. PUBESCENS.—Dull rufous, with short yellow down. 

Attelabus pubescens Melsh. Catal. 

Body above dull rufous, the whole surface covered with thick 
set, somewhat matted, short yellowish down: head with very 
small punctures at base, and large ones at tip; an elevated frontal 
_ longitudinal line ; rostrum much contracted between the antennx, 
dilated before: thorax with an indentation each side of the 
middle: elytra striate, and with irregular punctures: venter 
nearly naked: feet naked, bright rufous. 

Length about one-fifth of an inch. 

This species is not uncommon. Dr. Melsheimer found it on the 
leaves of the Corylus americana. 

[This was previously described as A. rhois Boheman.—L«c. ] 

2. A. SCUTELLARIS.—Black ; antennz and tarsi rufous ; scutel 
white. 

1826.] 


316 ACADEMY OF NATURAL SCIENCES 


Body deep black, much punctured: head short behind the

tenn rufous: thorax with numerous [253] dense punctures : 
scutel white: elytra slightly hairy, with punctured striz; the 
interstitial lines crenate : feet piceous: thighs with a slight angle 
on the inferior middle : tarsi rufous. 

Length one-tenth of an inch. 

I obtained two specimens on the Kalmia latifolia in July. 
It is a small species. 

[Is the type of Piazorhinus Schonh.—Lxc. } 


APION Herbst. 


1. A. RostRuM.—Black ; thoracic punctures large, dense; an 
impressed line, and punctures between the eyes. 

Rhynchites rostrum Melsh. Catal. 

Body entirely black: vertex impunctured: front with large 
punctures, and a longitudinal impressed line ; an impressed lon- 
gitudinal line between the antenne : thorax with large, concave, 
close set punctures ; an impressed, abbreviated line on the mid- 
dle of the posterior submargin: elytra striate, the strise rather 
wide, punctured, interstitial lines flat topped with a single series 
of small hairs. 

Length from the tip of the rostrum less than three-twentieths 
of an inch. 

This is a very abundant species. Dr. J. F. Melsheimer found 
it on the leaves of the Robinia pseudacacia ; and Dr. Harris of 
Milton, Massachusetts, informs me that it occurs in all its stages 
in the seed vessels of the wild indigo, (Baptista tinctoria,) in the 
months of August and September. I have also taken it in 
plenty on that plant. It seems to be allied to [254] the A. ni- 
grum Herbst., but it does not agree with his figure, nor sufli- 
ciently well with his description. 

[Afterwards described as A. Sayi Sch.—Lxc. ] 


BRACHYCERUS Oliv. Fab. 
B. HUMERALIS.—Body inequal, with punctures furnishing 
small hairs; humeral angles advanced. [

short, robust, filiform, white remote hairs: head transversely in- 
dented at the base of the very short rostrum, and with a very 
profoundly impressed abbreviated frontal line: antenna, termi- 
nal joint oval, acute: thorax inequal, widest in the middle, punc- 
tures dilated, preceded each side by small tubercles; anteriorly 
profoundly excavated, for the reception of the proboscis: elytra 
with double series of dilated punctures, each puncture preceded 
by an obtuse, slightly elevated tubercle, and each double series of 
punctures above separated by a slightly elevated interstitial line: 
humeral angles projected forwards, and embracing the lateral 
base of the thorax ; obtuse at tip, and rugged. 

Length seven-twentieths of an inch. 

Male more than one-fifth of an inch. 

Not uncommon near the head waters of the Arkansa river ; 
where [ obtained a few specimens, when with Major Long’s party. 

It is remarkable by the profound excavation in the anterior 
face of the trunk, for the reception of the rostrum; the antenne 
also do not perfectly agree with [255] those of the genus; these 
and other distinctions would authorize the formation of a new sub- 
genus, which may be named 

[The type of Lithodus ; afterwards named Thecesternus by Say ;

Length more than one-tenth of an inch. 

[Belongs to Corthylus Kr.—Lxc.] 

3. B. xyLocRAPpHuUS.—Rufous; elytra with series of punc- 
tures and short points on the posterior declivity. 

Bostrichus xylographus Melsh. Catal. 

Body somewhat polished, a little hairy, rufous : thorax rugous

tures, the interstitial lines with minute punctures, furnishing 
hairs; posterior declivity not truncate, but with small denticula- 
tions on the interstitial lines. 

Length much less than three-twentieths of an inch. 

This insect is abundant in forests of the pine, (Pinus mitis 
Mx.,) to which it is very destructive. Immediately beneath the 
bark, on the wood, it excavates a rectilinear groove, with short, 
equal, lateral grooves at right angles with the preceding. 

It varies considerably in size. 

4, B. porirus.—Rufous, with rather long hair; elytra entire. 

Apate politus Melsh. Catal.

with four denticulations, of which the second from above is the 
largest, and the inferior one is smallest and most acute; there 
are sometimes two very small ones above, near the suture. 

Length three-twentieths of an inch. 

This species is very closely allied to B. exesus. It is very de- 
structive to many species of pine. Mr. Z. Collins informs me 
that it depredates on the larch, (Pinus pendula? Aiton.) Dr. 
J. Mease recently exhibited to me some sections of limbs of the 
Silver pine (Pinus strobus) trees, which decorate the public 


squares of this city, now discovered to be seriously injured by 
the attacks of this insect. [258] 


HYLURGUS Latr. 

H. pentatus.—Head plane ; body reddish-brown ; elytra with 
impressed, punctured striz. 

Head blackish, with short hairs: antenne rufous: thorax 
blackish, passing into dull rufous at base ; with numerous hairs 
rather shorter than those of the head; punctured: elytra dull 
rufous, with numerous short hairs; striate, the striz deeply im- 
pressed, and giving the prominent basal edge a dentate appear- 
ance ; interstitial lines rough, with raised points, which are more 


prominent and destitute [distinct ?] towards the tip; beneath

black, with a honey-yellow band a little beyond the middle, and 
the edge of the tip somewhat dull yellowish: beneath dusky: 
feet honey-yellow. 

Var. a. Elytra honey-yellow, with a paler band.

I refer this little insect to the present genus, by its form of 
body. It is very like a small Cassida, and the head is equally 
concealed by the clypeiform thorax.

rower behind ; elytra striate. 

Inhabits Pennsylvania. 

Lyctus americanus ? Melsh. Catal.

2. L. geminatus.—Thorax longitudinally indented ; strix of 
the elytra geminate. 

Tnhabits Pennsylvania. 

Body depressed, dark reddish-brown, with short, prostrate 
hairs: head punctured : antennz rather robust, with short hairs : 
thorax gradually a little narrowed behind, with numerous large 
punctures; middle of the disk widely indented longitudinally : 
scutel convex, rounded: elytra depressed above; impressed strix 
placed in pairs; interstitial lines punctured. 

Length three-twentieths of an inch. 

[This is a species of Bothrideres Er., but very different from 
B. geminatus Hald., which was subsequently described as B. 
exaratus Mels.—LEc. ] 


3. L. H#MATODES.—Thorax with two indented lines; elytra 
with large, deep punctured striz. 

Lyctus hematodes ? Fabr. 

Body dark reddish-brown, a little depressed: head [263] 
with large, not profound punctures; an indented longitudinal 
space each side, between the antenne: antennz short, robust : 
thorax with large, somewhat deep punctures, and two dilated, 
parallel, indented lines on the disk: margin a little ele- 
vated, in the middle contracted ; elytra with dilated profound 
strie or grooves, in which are dilated, not deeply impressed 
punctures ; interstitial lines narrow, prominent. 

Length less than three-twentieths of an inch. 

This certainly approaches the description of LZ. hamatoces 
Fabr., and probably is the same; but as he describes that species 
to be carinated on the thorax, I have made out the above des- 
cription, that those who have an opportunity, may compare. 

I obtained may specimens under loose bark of the yellow-pine, 
on Chinquoteague Island, in October. 

The three species above described, correspond with the charac- 
ters of the genus Bitoma of Herbst, in having the antenne 
shorter than the head and thorax, and the mandibles not very 
obviously projecting ; yet they appear to me to be very properly 
retained in the present genus.

COLYDIUM Fabr. 

1. C. PARALLELOPIPEDUM.—Head with two tubercles ; thorax 
with two elevations, and an elevated line each side. 

Colydium parallelopipedum Melsh. Catal. 

Body dull rufous ; glabrous, punctured : head with an indented, 
transverse line, and two hardly prominent [264] tubercles, 
often obsolete: thorax quadrate, rather longitudinal ; two tuber- 
¢les before, which gradually dilate and disappear behind ; lateral 
submargin, with an elevated line hardly attaining to the base, 
and extending on the anterior edge, so as to join the opposite

elytra with hardly impressed, punctured striz, becoming small 
behind: feet pale rufous. 

Length less than one-fifth of an inch. 

This seems to be allied to C. bidentatum Fabr., of South

LATRIDIUS Herbst. 


L. puBrescens.—Reddish-brown; thorax each side irregu- 
larly denticulated. 

Inhabits Pennsylvania. 

Latridius pubescens Melsh. Catal. 

Body irregularly punctured, with numerous scattered hairs : 
thorax on the lateral edge having eight or nine irregular denti- 
culations: elytra without any series of punctures or Impressed 
line; hairs of the lateral margin prominent. 

Length neraly three-twentieths of an inch. 

Very different from the species which I described under the 
name of J. 8-dentatus, which has regular series of punctures on 
the elytra. 

[Belongs to Paratenetus, and seems to be P. punctatus Spin.,

SYNCHITA Hel. 


1. S. 4-currara.—Blackish-brown ; thorax canaliculate ; 
elytra each with two rufous spots. . 

Inhabits Arkansaand East Florida. 

Body with short curved hairs: head at tip tinged with rufous: 
thorax with a longitudinal groove each side on the submargin, 
continued on the anterior margin ; lateral margin a little concave, 
the edge denticulated : elytra with four dilated grooves, containing 
double series of punctures, anda marginal groove, containing 
but a single series of transverse punctures; interstitial lines 
slender; each elytron with an oblong longitudinal dull rufous 
spot at base, and another beyond the middle. 

Length less than three-twentieths of an inch. 

_ L obtained three specimens when with Major Long’s party in 
Arkansa, and several occurred in Florida. 
[Belongs to Ditoma Latr.—Lec. } 


2. S. GRANULATA.—Thorax granulated; elytra with granu- 
lated interstitial lines. 

Inhabits East Florida. [ 267] 

Body blackish-brown: head granulated, somewhat rufous 
before: antenne rufous, joints of the capitulum not distinctly 
separate: thorax covered with granulations; without grooves ; 
lateral edge denticulated : elytra with regular series of elevated 
granulated striz, and intervening, narrower, smooth ones. 

Length less than three-twentieths of an inch. 

Very distinct from the preceding. I obtained but a single 
specimen in Florida, and Mr. Nuttall presented me with three 
which he brought from Missouri. 

CUCUJUS Fabr. 

1. C. Braurratus.—Dark reddish-brown ; antennz more than 
half the length of the body; elytra with a large spot; thorax 
with a lateral impressed line. : 

Cucujus biguttatus Melsh. Catal. 

Head with numerous small punctures: thorax with numerous 
small punctures, not obviously crenate on the lateral edge, with 
an impressed line on the lateral submargin ; the margins slightly

paler than the disk: scutel pale: elytra with acute impressed 
striz ; a rather large, oval, pale spot somewhat before the middle, 
chiefly included between the second and third strive: beneath 
rufous. 

Length more than one-tenth of an inch. 

This is a common insect. It is so much like the C. bipustula- 
tus of Panzer, that we find some hesitation in admitting it to a 
distinct rank. That species, however, judging from Panzer’s 
figure, has the lateral [268] edges of the thorax obviously 
crenate, and the pale elytra spot is much larger than in the pre- 
sent species. 

[This species belongs to Laemophlous.—Lxc. | 


2. ©. MopEsTtA.—Reddish-brown ; antennz more than half 
the length of the body; thorax with a lateral impressed line ; 
elytra with punctured striz. 

Head and thorax reddish-brown, with numerous small pune- 
tures; the latter somewhat rounded, hardly narrower behind, 
with an obvious impressed longitudinal line on each lateral sub- 
margin: antenne considerably more than half the length of the 
body : elytra rather shorter than the abdomen, pale testaceous, 
immaculate; striz obtuse, hardly impressed, with large punc- 
tures: beneath reddish-brown. 

Length more than one-twentieth of an inch. 

This small species occurs in East Florida, and was obtained by 
Mr. Maclure’s party. Itis about equal in size to C. testaceus 
Fabr., of Europe, but is a very different species. In the form 
of its antenne, this species approaches the genus Brontes.

LAMIA Fabr. 


1. L. MAcuLA.—Brownish; sides of the thorax and spot on 
the elytra gray. 

Cerambyx macula Melsh. Catal. 

Head brownish above, grayish before, and gray on the cheeks : 
antennee a little longer than the body, dull rufous; the joints 
blackish at their tips: thorax slightly inequal, with very obtuse, 
obsolete tubercles; lateral spine none, substituted by a hardly 
elevated tubercle ; above brownish, with two longitudinal, [269] 
1826.] 


328 ACADEMY OF NATURAL SCIENCES 


distant blackish lines; sides beneath the lines gray : elytra pune- 
tured ; each with six lines of minute black spots, one of which is 
at the suture, and another on the lateral margin; a large trian- 
gular gray spot on the lateral middle, rarely reaching the suture: 
thighs clavate, black: tibize dull rufous, annulate with dusky. 

Length three-tenths of an inch. 

This species frequently occurs. 

[Belongs to Leptosty/us, Lec. Journ. Acad. Nat. Se. Phila. 2d

2. L. currata.—Elytra with minute elevated points, and 
about six obsolete gray spots. j 

Lamia 6-guttata Melsh. Catal. 

Body brownish: antennz a little longer than the body, obscure 
rufous; the joints dusky at their tips: thorax a little inequal, 
with hardly elevated, very obtuse tubercles; lateral spine none, 
being substituted by a slightly elevated tubercle: elytra punc- 
tured, each with six lines of minute black spots, which are each 
elevated, reflected, and acute ; about six obsolete gray spots on 
each, of which one-is sub-marginal behind the humerus, a minute 
one is upon the middle, and the third is small, subsutural, and 
behind the middle: thighs clavate, blackish: tibize dull rufous, 
annulate with dusky. 

Length nearly seven-twentieths of an inch. 

This species resembles the preceding, but it may be distin- 
guished by the want of the large gray lateral spot of the elytra, 
and more essentially by being armed with reflected points on the 
elytra. It also resembles the ZL. aculifera nobis, but is destitute 
of the whitish elytral band, and the general form of the body is 
different from either, being less robust. 

[A species of Leptostylus, which I have failed to identify ; it 
seems to be most like L. commixtus.—LEc. ] [270] 


3. L. pasycerus.—Antennz hairy beneath; elytra with 
minute elevated points. 

Body light brownish-cinereous : antennz a little longer than 
the body, with rather long, close-set hairs on the inferior side: 
thorax without obvious tubercles: with two obsolete, longitudi- 
nal, approximate, brown lines: elytra with a commom arcuated 
black line, extending from one humerus to the other; numerous,

rather large, irregular punctures ; a few series of distant elevated 
black points ; an obsolete common white band behind the mid- 
dle: thighs clavate: tibize not annulated. 

Length three-twentieths of an inch. 

This may be distinguished from either of the before mentioned 
species ; by the pendant hair of the inferior side of the antenne, 
&e. The white band is sometimes altogether wanting; and if 
very closely examined, the black points of the elytra will be 
found to consist of fasciculated hairs. 

[This is the type of Heyrus Lec., Journ. Ac. Nat. Se. Phila.,

Cerambyx analis ? Melsh. Catal. 

Body dull reddish-brown : head longitudinally deeply indent. 
ed on the vertex : antennze considerably longer than the body ; 
incisures blackish: thorax above, destitute of tubercles, but with 
three small black spots, placed 2, 1; a short tubercle, abruptly 
acute at tip, each side before the posterior angles, which are 
emarginate; posterior margin with a transverse indented line: 
scutel blackish: elytra irregularly [271] punctured; a few 
black dots, consisting of tufts of hair, chiefly along the suture; 
region of the scutel dusky; a blackish marginal abbreviated line 
from the humerus; a blackish line margined with gray, extends 
from the middle of the suture, obliquely backwards, towards the 
exterior margin. 

Length nearly three-tenths of an inch. 

This species is not very rare in Pennsylvania; I also obtained 
one in the N. W. Territory.

blackish bands. 

Antenne nearly twice as long as the body: thorax equal, with 
an acute spine each side, near the posterior angles, which are 
emarginate ; a gray mark behind the middle, in the form of a W: 
elytra yellowish-white ; a blackish band at base, decurrent behind 
along the suture ; a narrow oblique band before the middle, not

6. L. spinosA.—Covered with short, prostrate gray hair; an- 
tennz gray and black. 

Saperda spinosa Melsh. Catal. y 

Head deeply indented between the antenne: labrum piceous : 
antennz longer than the body, black, each joint gray at base: 
thorax cylindrical, immaculate; an acute, slightly recurved spine 
near the posterior angles; elytra with numerous small impressed 
[272] punctures, at tip truncated: venter with a series of almost 
concealed black spots on each side. 

Length more than three-tenths of an inch. 

The general form is that of a Saperda; but, agreeably to the 
generic characters, the spines of the thorax determine the affinity. 

[I formed a special genus Dectes for this insect, but it seems 
to be scarcely distinct from Liopus.—L«c. ] :

Body rather slender, ferruginous, with very short hairs: head, 
space between the antennze more elevated ; a longitudinal impress-

hairy, a little longer than the body; with numerous spines be- 
neath, particularly on the third or fourth basal joints: thorax 
rounded, a little narrower before, widest behind the middle: ely- 
tra very pale ferruginous; without any striz or punctures, instead 
of which, are very slight depressions, furnishing very short hairs ; 
on the middle of each elytron is a longitudinal obvious nervure ; 
tip acutely rounded: thighs, anterior ones more robust than the 
posterior pairs. 

Length more than three-fifths of an inch. 

The spines on the inferior surface of the antenne, are not 
confined to the tips of the joints, as in some species, but occupy

the surface from base to tip; they are obsolete on the first, 
second, and terminal joints. The species is rare.

two black tubercles above, rather before the middle, placed trans- 
versely, and a short spine each side on the middle of the length 
of the thorax: elytra rather paler than the thorax; each with 
two double, somewhat elevated bright yellow, abbreviated very 
short lines; the two members of the basal spot equal, the othe 
spot is placed on the middle, and its inner member is shorter 
than, the exterior one ; tip two-spined, the exterior spine longest . 
intermediate and posterior thighs two-spined at tip, the inner 
spine rather longest. [276 | 

Length nine-tenths of an inch. 

This insect is not uncommon. It is related to S. 4-maculatus 
Fabr., S. maculosus Fabr., S. didymus Oliv., all of South 
America, and WS. stigma Oliv., of Cuba. It differs from the first, 
to which it is more closely related than to either, by the equality 
of the two members of the basal double spot of the elytra, and 
by having only two tubercles on the back of the thorax ; from 
the maculosus it may be distinguished by its greater size and 
simple pale color ; from didymus by its smaller size, and not hav- 
the third and fourth joints of the antenne more hairy than the 
other joints ; from stigma by having the basal spot of the elytra 
double.

with a grooved prominence between the eyes, terminating ina 
short carina: antenne but little longer than the thorax: thorax 
with a naked dorsal vitta: elytra with the hair more densely 
arranged in some parts, so as to exhibit the appearance of small 
spots, which are arranged in two bands, in each of which are 
two spots each side, the second band is on the middle ; near the

Length three-tenths of an inch. [ 280 | 

This is very different from the preceding in the form of the 
thorax, as well as in color, Xe.

Rhagium rufipes Melsh. Catal. 

Body slender, punctured: head transversely much indented 
near the nasus: palpi pale rufous: antenne situated on a tuber- 
cle: thorax with a small tubercle, rather behind the middle on 
eacn side; an anterior and posterior, transverse, impressed line : 
elytra acutely rounded at tip: feet pale rufous; beneath dull 
plumbeous.

of Megerle. The name rujipes, is pre-occupied in this genus. 

[The type of Encyclops Newman, but described by him as L. 
pallipes.—LKEc. ] 

5. L. SPHHRICOLLIS.—Black ; thorax contracted on the poste- 
rior margin; feet varied with yellowish. 

Body with very short hairs, somewhat sericeous: labrum and 
anterior margin of the nasus yellowish: mandibles and palpi 
yellowish, at tip piceous: thorax globular in the middle; ante- 
rior and posterior margins much contracted: elytra punctured ; 
the punctures large at base, small towards the tip of the elytra: 
feet yellowish ; thighs at tip, and tibia at base, blackish. 

Length nearly one-third of an inch. 

I received this insect from Mr. Charles Pickering, of Salem, 
Massachusetts, to whom I returned for it the name of L. pubera ; 
but on a strict comparison, I find that by the form of the thorax,

it is quite different from that species, and much more closely re- 
lated [281] to the L.rujicollis nobis, from which it differs chiefly 
in the color of the thorax. 


ORSODACNA Fabr. 


1. O. TrIPLA.—Rufous ; feet yellowish ; thorax dentate each 
side. 

Crioceris asparagi Melsh. Catal. 

Body rufous, punctured: head coarsely and confluently pune- 
tured ; before the antenne yellow : antennz with the basal joints 
yellow at their tips: mandibles black at tip: thorax widest in 
the middle, with coarse, confluent punctures ; lateral edge with

densely and confluently punctured ; the longitudinal line, as well 
as the lateral tubercles, indistinct ; color brassy-green: elytra a 
little inequal near the suture; slightly truncated, and not de- 
curved at tip: with regular distinct striz of punctures : beneath

This species is nearly equal in size to the palmata Oliy., which 
is the D. anea of Melsh. Catal. ; but that common insect has the 
dorsal thoracic line and lateral tubercles well defined, the third 
joint of the antennze nearly double the length of the second, and 
the tips of the elytra more profoundly emarginated; the thorax 
is moreover transverse. JI may observe, with respect to the 
palmata, that the male only has the anterior tarsi dilated.

1. E. prnt.—Brassy, with short whitish hair ; antennz obscure 
rufous. 

Body rather dark brassy polished, punctured, with short 
whitish hair: head with an impressed longitudinal line on the 
front : antennz and palpi dull rufous : thorax, as well as the head, 
slightly tinged with cupreous: scutel cupreous: elytra destitute 
of striz or lines: beneath reddish-brassy, more densely covered 
with the whitish hair than the superior surface: feet not so 
thickly hairy, dark rufous. 

Length seven-twentieths of an inch. 

I received this insect from Dr. J. F. Melsheimer, [ 296] under 
the name which I have adopted; he informed me that its favor- 
ite food is the different species of Pinus.

destitute of striz or lines: beneath reddish-brassy, covered with 
whitish hair: feet very dark rufous. 

Length nearly three-tenths of an inch. 

Resembles the preceding, but is always smaller, and it may be 
at once distinguished from it by the color of the hair, which on 
the superior surface is decidedly ferruginous. 


CHRYSOMELA Linz. Latr. 


1. C. cH#RULEIPENNIS.—Blue polished ; thorax and feet ru- 
fous; antennz and tarsi black. 

Head punctured, blue-black: antennz black, basal joint ru-

margin, and another on the posterior submargin: scutel blue : 
elytra polished blue, numerously punctured, the punctures irre- 
gularly situated, sometimes confluent: beneath blackish-blue : 
feet pale rufous: tarsi black: anus rufous. [ 297 | 

Length more than three-twentieths of an inch. 

A beautiful and rare species, an inhabitant ofthe North West 
Territory. I received a specimen from Mr. John P. Brace of 
Litchfield, and another from Dr. T. W. Harris. 

This is the very abundant C. polygoni, which is probably in- 
troduced from Europe.—Lec.] 


2. C. sprr#A[E].—Green; elytra pale yellow, with green spots, 
a common and sutural line trifid at base. 

Head dark green, tinged with brassy: antennz and palpi ru- 
fous : thorax dark green, tinged with brassy: elytra pale yellow, 
sometimes tinged with rufous: each with about seventeen un- 
equal small green spots; a larger lunate one originating on the 
humerus ; a common green sutural line, which sends off a lateral 
short branch on each side near the base : beneath blackish-green : 
feet rufous. 

Length a quarter of an inch. 

I received several specimens from Dr. Jno. F. Melsheimer, 
under the name which I have adopted. He informed me that 
he found them on the Spirea opulifolia Muhl. Catal. I have 
also found them near Philadelphia, and in Missouri. It is very 


[Vol. V.

closely allied to the C. philadelphica Fabr., but is smaller, and 
the sutural line is always common ; whereas in the philadelphica 
there is a slender subsutural line on each elytron always insu- 
lated from the suture throughout its whole length. 

It has also a general similarity to the multipunctata nobis, but 
that species is larger and more oblong, the elytral spots more 
numerous, and arranged in a different manner, and the head and 
thorax are of a different color. [298] 


HELODES Fabr. 


H. rrivitrata.—Blue-black ; margin of the thorax and two 
elytral vitte yellow: y 

Body punctured : head entirely blue-black, with an impressed 
frontal line divaricated before: thorax with somewhat sparse 
punctures ; lateral margins yellow, this color being contracted in 
the middle on the inner side: elytra with punctured stirs: su- 
tural margin yellow; vitta on the middle not reaching the tip, 
and exterior edge blue-black : feet immaculate: venter with the 
caudal segment margined behind with dull yellowish. 

Length more than one-fifth of an inch. 

This insect was sent me by Mr, Charles Pickering, of Salem. 
It is so closely allied to the H. phellandrii Linn., in size, form, 
description, and disposition of colors, that I have hesitated to 
consider it as distinct. The chief difference which I have been 
able to discover, consists in the circumstance, that the feet in the 
phellandrii are partly yellow, whilst those of the present species 
are perfectly immaculate. Still it is highly possible that it may 
prove to be a variety of that well known insect.

B. FuscrTaRsis nob.—When describing this species I observed 
that “The scutel of my specimen is wanting, I cannot therefore 
ascertain its number of spines.” I have since obtained individu- 
als in Indiana, and find that the scutel is altogether destitute of 
spines or radii. It differs in this respect from all the known 
species.

If it be true that the male in this genus, is distinguished [168] 
invariably by the contact of the eyes on the vertex, then the 
male of the present species is nearly double the size of the fe-

vure: poisers and wing scale pale ferruginous: abdomen pale 
ferruginous, black at tip: feet black ; thighs at base, and coxe 
pale ferruginous; posterior tibiae deeply ciliated with dilated 
scale-like hairs. 

Length three-tenths of an inch. 

This cannot be the Thereva lanipes of Fabr. of which the 
thoracic lines are said to be white, and the abdomen black, im- 
maculate; neither can it be the T’hereva pilipes Fabr., which is 
said by Wiedemann to be a Phania, for the antenne of our species 
have not the third joint “elongated and linear” as in that 
genus. It seems also allied to Dictya pennipes Fabr., which, 
however, has a large ferruginous spot on the wing. 

[This isa Trichopoda Latr., previously described as 7. (Dictya) 
pennipes Fabr. Say described the male ; the female has a ferru- 
ginous spot at the base of the wing, and the abdomen is entirely 
ferruginous.—SACKEN. |

“ COTTON PLANT. 369 


_ Correspondence relative to the Insect that destroys the Cotton Plant. 
oa 


To Tuomas Say, Esq., 
Prof. of Natural History, University of Pennsylvania. 


‘a Sir —I have for several years ‘paid some attention to an in- 
sect which has infested our cotton, whose character and species 
‘Ihave been very desirous of ascertaining. I addressed a letter 
to Mr. Stephen Elliott on this subject, and he referred me to 
you, not being able to give me the description wanted. TI also 
sent to Dr. Samuel Mitchell of New York, but he likewise was 
_ not able to give any satisfactory account, and referred me to Mr. 
Le Conte]; but owing tosome adventitious circumstances, I never 
heard from him, and have now taken the liberty of addressing 
_ you, although an entire stranger, and must make my love of the 
sciences generally, as well as my desire to be acquainted on 
this particular point, my excuse. I have therefore sent a box 
containing the moths. They were put into the box in the cater- 
_ pillar state, with a few cotton leaves to feed on. After a time 
they went into the pupa state, and finally became moths. I have 
_ written an essay on these insects which is incomplete, from not 
_ knowing their scientific name and character. If you will so far 
- oblige me, please address a few lines on the subject to your obe- 


_ dient servant, C. W. CAPERS. 


New Harmony, Nov. 1, 1827. 

_ Sir:—I received your interesting communication of the date 
of Jan. 21, not until Thursday last, and how to account for its 
_ long detention I know not. It was brought by private convey- 
ance in due time from Philadelphia, so that the delay must have 
occurred in that city, or on its way there. Any future package 
"you may wish to send me, may be confided to the care of a house 
in New Orleans.

370 COTTON PLANT. 


I have carefully examined the contents of the box which 
accompanied your letter. It contained several cotton moths, 
which are much injured, but as far as I am enabled to judge by 
their remaing characters, they constitute a new species, of which 
I have made the following description : 


NOCTUA Fabr. 

N. xvurna.—Olivaceous, tinged with vinaceous; superior 
wings with a black spot. [814] 

Description. —Head vinaceous, with a small whitish tuft before: 
antennze pale honey-yellow, of moderate length, covered with 
scales above and short hair beneath: labrum rounded, small : 
mandibles conic, whitish, with a fascicle of sericeous fulyous hair 
on the inner base: maxillze as long as the antenne, papilaceous 
towards the tip: palpi densely covered with short, equal scales, 
which are intermixed rufous and white; second joint much 
longer than the first; third joint very distinct, conic, linear; 
thorax vinaceous with more or less of olivaceous, particularly 
on the sides: superior wings vinaceous towards the posterior 
margin obsoletely olivaceous; a little above and partly on the 
second bifurcation of the post costal neryure is an oblique sub- 
oval, blackish spot, in which are paler scales, forming almost a 
double pupil: posterior to this spot is an obsolete, much undu- 
lated, interrupted, dull rufous line, reaching the anal margin 
near the middle and the costal margin at two-thirds the distance 
from the humerus: behind this line is a distinct one, and in 
some specimens a still less distinct one towards the base of the 
wing, accompanied by a small spot : inferior wings on the inferior 
page with a slight, slender, rufous band: anterior tibiz with a 
spine: posterior tibiae with spines on the middle and tip: claws 
distinct, emarginate beneath. 

Length to tip of superior wings nine-tenths of an inch. 

Larva sixteen-footed, spotted; eyes spotted: beneath immacu- 
late, simple. Pupa simple, dark chestnut or blackish ; three of 
the abdominal segments with dilated, rufous, posterior margins. 

In the above description, if any errors occur as regards color, 
you can rectify them from more recent and perfect specimens. 
With these moths a single individual occurs of the Noctua Iota 


COTTON PLANT. 371 


Linn. Whether or not this is a confederate of the aylina in de- 
stroying the cotton plant, you are best able to judge ; but I should 
rather suppose that its ravages are not particularly directed against 
that plant, and that its presence here is rather fortuitous. 

One of the small vials contains a Gryllotalpa Americana. 

I take the earliest conveyance for this letter, in hopes it may 
reach you early enough to be of some utility.

Chrysomela scalaris Le C. may possibly prove to be the @.

of the suture, which he says is “ brunneus;” a specimen in my 
collection has a tinge of that color, and another has a slight ap- 
pearance of the lateral thoracic indentations, which Weber attri- 
butes to his species. At any rate, I referred the species to that 
description until another insect could be found better adapted 
to it. 

There can be no doubt respecting priority in relation to the 
above names.

with a semiocellate blackish mark, and on the posterior margin 
pale bluish, including a black line; inferior portion tinged with 
gray, and with several moveable internal spots; frontal vesicle 
dull whitish, above reddish-brown, dull yellowish in the middle, 
with a quadrate blackish spot; [10] thorax with two anterior 
green lines, and on the pleura beneath each wing, also a green 
oblique line, between the bases of the wings are green spots ;

somewhat dilated in the middle, gradually narrowed to each ex- 
tremity, and rounded at tip; feet black; thighs rufous at base. 

Length three and three-fifths inches to tip of caudal appendices.

at the exterior tip prominent mucronate. 

Length three inches. 

@ Wings with a trace of ferruginous on the anterior portion ; 
foliaceous appendages rather smaller, lanceolate, acute. 

Drury in his figure represents the abdomen as entirely green ; 
but this is a mistake ; his dried specimen had this part brown, 
and supposing it to have been green when living, he figured it 
so. Can this be vesiculosa L.? It is allied to the formosa Van- 
derlinden, which, however, appears to have a black, angulated, 
dorsal vitta on the abdomen, and the eyes are described to be 
green.

It belongs to the genus Gomphus Leach. 

10. A. stigmMata.—? Body yellow ; stemmata. rather large ; 
thorax with a double brown arcuated vitta before, each side of 
which is an abbreviated, oblique, brown line, and another brown

This species agrees with the short description in Turton’s 
Linn., of the trimaculata Degeer, and I should certainly consider 
it the same species, if Olivier had not decided the trimaculata 
to be the same as the bifasciata L.

It is on the authority of Olivier, that I quote Degeer’s trima- 
culata for this species, as I do not possess the work of the latter 
author.

7. L. TERNARIA.—Wings with a fuscous line or spot at base . 
a spot or band in the middle and another near the tip. 

Inhabits Massachusetts. 

*, Head, a black line between the antennz; eyes above in 
contact by a curved line; posterior lateral canthus of the eyes 
with two yellow spots; pleura with two oblique lines; wings 
with a pale ferruginous vitta, extending from the base along the 
anterior submargin to the middle, thence along the margin to the 
tip, interrupted by the stigma, which is black; on the middle of 
the costal margin a fuscous spot, and from the stigma a fuscous 
band, which does not reach the tip; at base of the posterior 
wings, behind the vitta, is a rather large and conspicuous, irre- 
gular, fuscous spot, reticulated with whitish nervures; anal 
membrane white; margined cellules ten or eleven between the 
middle and stigma; abdomen greenish-yellow at base, and black 
at tip, with a yellow lateral vitta ; anal processes fusiform, black, 
subacute ; inferior process hardly one-third as long as the others.

9 The spot of the middle of the wing is extended into a 
semifascia, and the subterminal band is more distinct; at the 
base of the posterior wings is a black, securiform line, one-fourth 
the length of the [22] wing, behind which isa large, pale ferru- 
ginous spot, reticulated with whitish nervures. 

Length one inch and seven-tenths. 

At first sight resembles L. bifasciata Fabr., but is quite dif- 
ferent; the ultimate wing band is not terminal, the anal pro- 
cesses also are dissimilar. 

I have not seen any other specimens than the sexes sent me 
by Dr. Harris for examination. 

In some of its characters it resembles the LZ. guadrimaculata 
Linn., of Europe, but that has not the terminal wing bands.

8. L. Lepa.—Wings at tip, point on the costal margin, and 
line at base, brown. 

Inhabits the United States. 

L. Lydia, Drury, Ins. Vol. 2, ea 47, fig. 1, and Oliv. Ency. 
Meth. p. 570, No. 8. 

Thorax brown, with a pale vitta; pleura greenish ; wings with 
a blackish point on the middle of the costal margin, and oblong 
blackish carpus ; terminal half of the anterior margins and tip 
fuscous ; a slender black line, at base, equal in length to the 
breadth of the body; abdomen with a broad, yellowish-rufous 
lateral vitta ; anal segment remarkably short ; on each posterior 
orbit of the eyes are two yellow spots. 

Length about two inches. 

Var. a. Fuscous tint on the anterior margin of the wings ob- 
solete, being only a very slight tinge of ferruginous. 

Drury’s figure represents this species very well, but the fuscous 
tips of the wings are generally broader, though sometimes alto- 
gether wanting. [23] 

Olivier has two different species of the name of Lydia, both of 
which he quotes from Drury. We have therefore changed the 
name of the present species. 

[The name L. Lydia Drury, 2, pl. 47, fig. 1, must be restored

9. L. quADRUPLA.—Thorax with a whitish vitta; abdomen 
with a lateral, yellowish one ; wings with a bicolored stigma, and 
basal blackish line. 

Inhabits Massachusetts. 

This insect very closelyr esembles L. Leda 8. It differs, how- 
ever, in being smaller, and in haying the stigma larger, white, 
with a black tip. The male is destitute of the black wing tips, 
and like the female, has the exterior half of the costal margin 
tinged slightly with ferruginous. The anal processes are short, 
subcylindric, a little smaller at base, and beneath, towards the 
tip, minutely denticulated ; at tip a small point. 

The sexes were sent me by Dr. Harris. 

Length from one inch and three-fifths to one inch and seven- 
tenths. 


10. L. BASALIS.—Wings fuscous on the basal half. 

Inhabits the United States.

dark fuliginous opaque, on the basal half, beyond which is a 
broad, milk-white almost opaque band ; stigma blackish ; abdomen 
somewhat depressed, of equal diameter nearly to the tip, dusky, 
with a lateral dull yellowish vitta ; beneath black-brown. 

Length nearly two inches. 

[In a note attached to this description by Mr. Say, [24] is a 
reference to L. marginata Degeer. Wings fuscous from the 
base nearly to the middle. 

Ix. dimidiata Fabr. V. Enc. Meth., refers to Seba, which is 
quite different. Said to be from Surinam, and is much smaller,

12. L. acura.—Wings immaculate; body greenish-yellow ; 
abdomen with the edges blackish. 

Inhabits Mexico. 

° Body greenish-yellow ; eyes approaching above, but hardly 
touching, the nearest parts not rounded, almost acute ; orbits be- 
fore and above with a black edge; stethidium immaculate ; ad- 
domen pale yellowish-brown, yellowish green at base ; the acute 
longitudinal edges, above and each side, black ; the [25] trans- 
verse edges and a subbasal transverse line on each segments fus- 
cous ; venter also with a black line; feet black; thighs yellow- 
ish, with the spines black, and on the anterior pairs a line be- 
neath. 

Length one-inch and three-fifths. 

The quadrilineate abdomen, with the subacute proximate per- 
tion of the eyes distinguish this species ; the abdominal lines are 
not dilated, but limited to the edge of the caring. The frontal 
vesicle is greenish-yellow, with a dark transverse line at the an- 
tenne.

particularly of the posterior pair, and on the middle ; anal mem- 
brane blackish ; stigma rather large and blackish ; feet black ; 
coxee and trochanters yellow ; inferior side of the anterior thighs 
yellow; abdomen with a dorsal black vitta, including the carina, 
and a lateral black vitta above the lateral carina; lateral carina 
black; these vittea are more and more widely confluent at the 
sutures, towards the tip of the abdomen, which is entirely 
black. [26 ] 

Length from one inch and a half to one inch and three-quarters. 

It may be distinguished by the blue top of the frontal vesicle, 
and the ferruginous mark at base of the wings. The ferruginous 
cloud on the middle of the wings is often altogether wanting. 
It also varies in having no abdominal vitte, excepting a vestige 
at base. The blue color sometimes extends down the front. The 
abdomen is also sometimes blue, and the thorax sometimes black. 
Drury describes the abdomen of the female as yellow, with black 
annulations, and that of the male blue. 

The inferior anal process is at least two-thirds the length of 
the superior ones, which are arcuated, with a tooth beneath near 
the tip, and at tip acute.

inch in length, more evident on the inferior wings; stigma brown; 
about nine marginal cellules between the stigma and middle of 
the wings; tergum bright sanguineous, above carinate, immacu- 
late, on each side a black line, which dilates [27] towards the 
tip of each segment ; anal appendices deflected, longer than the 
inferior conic one, mucronate, and with a strong tooth on the in- 
ferior middle; feet blackish, venter pale. 


Length one inch and a half.

tending to the middle; that of the superior pair chiefly on the 
anterior half of the wing; that of inferior pair more obvious, 
much broader, extending nearly to the thinner margin.

culations beneath, an angle beneath near the tip, and the tip 
acute ; inferior process extending nearly to the tip of the superior 
pair. 

Length about one inch. [28] 

Very much like a small specimen of rubicundula 8., but dif- 
fers in several characters, particularly in the anal processes, and 
in the number of marginal cellules.

wings immaculate ; stigma fuscous ; anal membrane narrow, black ; 
feet black; thighs on their posterior side brownish; abdomen 
brownish, with slender incisural black lines and black edges to 
the carinze ; a black spot on each, excepting the three basal ones ;

submarginal spots of the wings, are sometimes obsolete, or alto- 
gether wanting anal appendices $ arcuated, unarmed; inferior 
process a little curved upward, over three-fourths the length of

Of this fine species, Mr. Nuttall presented me two individuals 
which he obtained from Missouri. The bright sanguineous color 
of the wings in one sex terminates abruptly, and in the other the 
very pale yellowish-brown color of the same part gradually disap- 
pears towards the middle. 

In the A. cata Drury of South America, (A. Brightwelli Kirby?) 
the inferior pair of wings have a reddish spot at tip. 

It is very abundant in some situations in Indiana, and is easily

of the tip of the abdomen and of the thorax, which arrests the 
attention when the insect is on the wing. [41] 

But it varies much in color. The vitte of the abdomen are 
more or less dilated, sometimes hardly visible; the head and 
thorax are, in some individuals pearlaceous-blue, and the ultimate 
abdominal segment varies from dull yellowish, with blackish lines, 
to a bright pearl-blue, sometimes dull-yellowish with a pearlace- 
ous-blue lateral spot on each. 

It is very common. 

The female has two small angulated processes beneath the tail, 
which do not extend beyond the tip of the abdomen, the nails at 
their extremities are curved downwards; the hooks at the tip of 
abdomen of the male are not obvious. 

The description is from recent specimens. The fine blue color 
disappears in the cabinet specimens.

C. ocuLATA.—Pea-green; head and thorax spotted; tarsi 
brownish. 

Inhabits the United States. 

Antenne pale brownish ; first joint white, with a sanguineous 
band at base above, second joint black; eyes golden; palpi al- 
ternately black and white; labrum with two dilated sanguineons 
vittze ; between the eye and mouth is a black, angulated line ; 
base of the anteunz enclosed by two black circles; which are 
tinged with sanguineous above; above each antenna are two 
blackish spots, of which the anterior ones are sometimes con- 
fluent with the [46] circles of the antennz ; thorax with two

This beautiful little insect is very common. When irritated, 
it diffuses a strong offensive odor, similar to that of human ex- 
erement. It is the analogue of the C. perla L., with which I 
have hitherto confounded it, but, judging by Donovan’s figure, 
it is never so large. Donovan says the perla stinks before a 
storm; our species has always that quality when irritated or 
alarmed.

A Monograph of North American insects, of the gonus CICINDELA. 
Read, 7th November, 1817. 


Tt will perhaps be thought necessary, previous to entering into 
a technical detail of the characters of the genus Cicindela, and 
of the indigenous individuals which are comprehended by it, that 
some account of the manners of this sprightly tribe should be 
given, and of such circumstances, relating to them, as may serve 
to present them to the recollection of the general observer. [I 
shall accordingly proceed to state, that thése insects usually fre- 
quent arid, denudated soils; are very agile, run with greater celer- 
ity than the majority of the vast order to which they belong; and 
rise upon the wing, almost with the facility of the common fly. 
They are always to be seen, during the warm season, in roads or 
pathways, open to the sun, where the earth is beaten firm and 
level. At the approach of the traveller, they fly up suddenly to 
the height of a few feet, pursuing then a horizontal course, and 
alighting again at a short distance in advance, as suddenly as 
they arose. The same individual may be roused again and again, 
but when he perceives himself the object of a particular pursuit, 
he evades the danger by a distant and circuitous flight, usually 
directed towards his original station. It is worthy of observation, 
as a peculiarity common to the species, that when they alight, 
after having been driven from [402] their previous position, they 
usually perform an evolution in the air near the earth, so as to 
bring the head in the direction of the advancing danger, in order 
to be the more certainly warned of its too near approach. 

They lead a predatory life, and as it would appear, are well 
adapted to it, by their swiftness, and powerful weapons of attack. 
The beaten path, or open sandy plain, is preferred, that the 
operations of the insects may not be impeded by the stems and 
leaves of vegetables, through which, owing to their elongated 
feet, they pass with evident difficulty and embarrassment. They 


416 TRANSACTIONS OF THE 


prey voraciously upon the smaller and weaker insects, upon larvee 
and worms, preferring those whose bodies are furnished with a 
membranaceous cuticle, more readily permeable to their instru- 
menta cibaria. 

The same rapacity is observable in the larva, or imperfect stage 
of existence, of these insects, that we have occasion to remark in 
the parent; but not having been endowed by nature with the 
same light and active frame of body, they are under the neces- 
sity of resorting to stratagem and ambuscade for the acquisition 
of the prey, which is denied to their sluggish gait. The remark 
is, I believe, generally correct, though liable to many signal ex- 
ceptions, that carnivorous animals display more cunning, industry, 
and intelligence, than those whose food is herbs, for the acquisi- 
tion of which, fewer of the mental attributes are requisite; we 
see throughout the amimated creation, that the development of 
these qualities, as well as of the corporeal functions, are in exact 
correspondence with their necessities; and that where a portion 
of the one is withheld, an additional proportion of the other is 
imparted. This larva has a very large head, elongated abdomen, 
and six short feet placed near the head; when walking, the body 
rests upon the earth, and is dragged forward slowly by the feet. 
Notwithstanding these disadvantages they contrive means to ad- 
minister plentifully to an appetite, sharpened by a rapid increase 
of size. A cylindrical hole is dug in the ground to a consider- 
able depth, by means of the feet and mandibles, and the earth 
transported from it, on the concave surface of the head; this cell is 
enlarged [403] and deepened, as the inhabitant increases in size, 
so that its diameter is always nearly equal to that of the head. At 
the surface of the earth they lay in wait for their prey, nicely 
closing the orifice of the hole by the depressed head, that the 
plain may appear uninterrupted; when an incautious or unsus- 
pecting insect approaches sufficiently near, it is seized by a sudden 
effort of the larva, and hurried to the bottom of the dwelling, to 
be devoured at leisure. These holes we sometimes remark, dug 
in a footpath ; they draw the eye by the motion of the inhabitant 
retreating from the surface, alarmed at the approach of danger. 

I shall now proceed to offer some remarks on the affinities of 
this genus, and endeavor to point out the differential traits, by 

[Vol. I. 


AMERICAN PHILOSOPHICAL SOCIETY. 417 


which it may be distinguished from its congeners. Cicindela, 
according to Linnzus, included not only all the insects, which 
would at this day be referred to it, but many others, which, how- 
ever closely allied by habit, are widely distinct in the formation 
of their oral organs. These were separated by the celebrated 
systematists, Fabricius and Latreille, into several new genera, to 
which well defined essential characters have been affixed. These 
separations have been made upon the best possible grounds; the 
convenience of the student, and the approximation to natural 
method. So circumscribed, Cicinde/a presents a natural group, 
in which each individual so perfectly corresponds with the others, 
as well in its internal organization and parts of the mouth, as in 
habit, or general form of the body, that the entomologist finds 
no difficulty in distinguishing it from insects of neighboring 
genera, and referring it to its relative situation. 

The genera to which allusion is here made, as having affinity 
with the one under consideration, are principally Colliuris, Ther- 
ates, Megacephala, Manticora, Elaphrus, and Notiophilus. In 
constructing the essential character, I have endeavored to ascer- 
tain such traits as will at once, invariably, distinguish Cicindela 
from all other known genera of the Pentamerous Coleoptera, and 
prevent the occurrence of error in the reference of species to it. 
In external form, Cicindela [404] borders very closely upon the 
genera here enumerated, and in addition to evidence of frequent re- 
currence, furnishes us with ample proof, that if habit was the only 
character consulted in the formation of a system, animals of very 
different modes of life, and totally distinct in nature, would be 
blended together by artificial violence. Of the genera above 
mentioned, the two last are very distinct from Cicindela, by the 
inarticulated maxillary nail, and by a deep sinus on the inner 
edge of the anterior tibia, characters which at once approach 
them to the Carati, notwithstanding the almost perfect similarity 
which Elaphrus bears to Cicindela in miniature, by the form and 
proportions of its body. The mentum or chin also of the former 
is not divided as it is in the latter genus, and it is worthy of 
particular remark, that in Notiophilus there exists the spine and 
recipient cavity of Elater. Colliuris is composed of two species, 
natives of the East Indies, and one of South America, distin-

418 TRANSACTIONS OF THE 


guished by the cylindrically-conic thorax, more elongated body, 
and narrow, transverse mentum, which is widely emarginated, 
without a conspicuous inner division, but in other respects much 
resembling Cicindela. A genus has been lately formed by Mr. 
Latreille, under the name of Therates, for an insect of the South 
Sea Islands, which Fabricius had named C. labiata. This has a 
strikingly discrepant peculiarity in the form of the intermediate 
palpi, which are abbreviated into a spine-like process. Manticora 
includes two species, indigenous to the Cape of Good Hope, 
which resemble Cicindela by the form of the mentum, in which 
there is scarcely any difference; the jaws also are similar, and the 
mandibles not unlike; but a good distinctive character rests in 
the palpi, of which the posterior are larger than the intermediate 
ones; the abdomen also is somewhat pedunculated, and embraced 
each side by the elytra. The last proximate genus which I shall 
notice, is that of Megacephala, of which at least two species, the ~ 
Carolina and Virginica, are natives of this country, and are 
principally found in the Southern States. In this genus, as in 
those before adverted to, there is no difficulty in pointing out 
good and substantial characters, by which [ 405 ] it may be read- 
ily known; the anterior palpi are elongated, and reflected, not 
equal to the intermediate ones, as in Cicindela ; the inner divis- 
ion of the mentum is much shorter and the front of the head 
convex. 

Having thus noted the differences existing between this genus 
and each of its neighboring genera, I shall next proceed to lay 
down its characters, distinguishing them into Essential, Artifi- 
cial'and Natural, for the first of which the preceding remarks 
will furnish materials ; and finally, I shall endeavor to describe 
the species with such accuracy and detail, that they may be 
readily known.

Obs. The sexes may be distinguished from each other by the 
three first anterior tarsal joints of the male being dilated, and 
hairy beneath ; the last segment of the body, with an obtuse sinus. 
The tarsi of the female are simple, the tail canaliculate towards 
the tip. 


1. C. vunGaris.—Obscure, on each elytron three whitish 
bands, two of which are curved, and the intermediate one re- 
fracted. 


Length more than three-fifths of an inch. 

Tnhabits North America. 

Desc. Head blackish or obscure cupreous, green at base above, 
front with cinereous hair; antenne, first, second, third and 
fourth joints green, furnished with a few white hairs before, ori- 
gin of the hairs in punctures, which are more obvious on the 
basal joint, remaining joints black, opaque ; labrum white, with 
three [410] black teeth at tip and four marginal punctures, one 
of which behind each of the lateral teeth, and one at each an- 
terior angle; mandibles white at the base, black within and at 
the tip; palpi above green, beneath purple, the second joint of 
the labials white. Trunk, thorax quadrate, inconspicuously nar- 
rowed behind, obscure cupreous, with distant hairs, submarginal 
impressed lines blue ; feet green ; thighs usually brassy-red above; 
elytra cupreous brown or blackish obscure, with minute, irregular, 
ereen punctures; suture and external edge cupreous, each ely- 
tron with an external lunule or curved line, originating on the 
humerus, sometimes interrupted on the margin and curved in- 
wards towards the tip of the elytron, intermediate band refracted,

wards, and terminating near the suture, posterior band, some- 
what lunate, terminal. Abdomen, tergum greenish blue, segment 
brownish or pale at tip; venter blue with a purple shade ; tail, 
and sinus of the male purple. 

This species I have always been accustomed to refer to C. tri- 
jfasciata, and it is not without considerable hesitation that I ven- 
ture to give it a distinct name. Mr. Melsheimer considered it 
as trifasciata, and that name in his catalogue refers to the in- 
sect under consideration ; it is also true, that it corresponds in 


[Vol. 1. 


AMERICAN PHILOSOPHICAL SOCIETY. 428 


every particular with the short description of that insect in the 
Syst. Nat. and also in the Syst. Eleut., but this circumstance 
alone is not sufficient to warrant us in concluding it to be the 
same, for in this instance, as in very many others wherein brief 
descriptions are concerned, several distinct species may be re- 
ferred with equal propriety to the same trivial name. Olivier, 
in his celebrated work, gives us a few additional characters of 
the trifusciata, the most important of which “on voit une raie 
interrompue, le long de la suture, jusque vers le milieu,” is 
with respect to our insect a [411] good discriminative charac- 
ter, in which this line or vitta never has existence; the size also 
as depicted by him, tab. 2, fig. 18, is not quite half an inch, 
whereas that of the vulgaris is full three-fifths. From these 
characters it must be evident that Olivier’s trifasciata is a dif- 
ferent insect from the one here described, and as he examined 
the various cabinets in which the insects described by Fabricius 
are preserved, I rely upon his knowledge of the Fabrician spe- 
cies, particularly as he gives the synonym of that author. 
Against the correctness of this decision it might be urged, that 
Fabricius, in his subsequent work, Syst. Hleut., does not refer 
to the above mentioned figure, neither does he quote Olivier at 
all under his description of ¢rifasciata ; but this objection, how- 
ever plausible, will have no weight, when we know that he refers 
to this very figure, the 18th, of tab. 2, for the C. punctulata, an 
insect with which it has no other than a generic affinity, and for 

which, on comparison, it could not be mistaken.

single tooth and eight submarginal punctures producing hairs ; 
mandibles white at the base, within dark green, tip black: palpi 
white, terminal joints green. Trunk, thorax with the submarginal 
lines blue, quadrate, not straitened behind ; elytra obscure, punc- 
tured irregularly with green, punctures larger than in [412] the 
preceding species, more conspicuously serrate at the hind margin 
and mucronate at the inner tip: anterior lunule originating on the 
humerus, continued a short distance on the margin, aud curved 
rather towards the base of the elytron, intermediate band divari- 
cated on the margin, so as to attain the lunules, but is sometimes 
interrupted before the posterior, refracted in a somewhat acute 
angle at the centre of the elytron, thence recurved nearly parallel 
with the suture, and dilated at its termination ; posterior lunule 
terminal; feet red-cupreous, hairy; trochanters purple. Abdo- 
men, venter blue, segments tipped with brassy ; tail purple. 

This insect does not appear to have been described except in 
the work to which the synonym refers; it had been previously 
overlooked, probably in consequence of its proximity in point of 
colors and marking to the preceding species, which it generally 
accompanies; but a small degree of scrutiny will detect a suffi- 
cient number of discriminative characters to warrant us in con- 
stituting of this insect a distinct species; in size its female is 
equal to the male of (. vulgaris, the punctures of the elytra are 
much larger, the intermediate band is so widely spread out upon 
the margin, as nearly to connect the anterior and posterior 
lunules, and the tip of the anterior lunule is curved towards the 
base of the elytra, and not obliquely towards the tip, as in the 
preceding species ; a striking difference also is perceptible in the 
upper lip which in that insect is three-toothed, but in the C. hir- 
ticollis it is one-toothed. Neither this nor the preceding species 
have been observed to vary in their colors or markings. 

[Ante, 2; this description and figure evidently refer to the 
species afterwards described as C. albohirta Dej. The figure is 
quite characteristic, and can by no means be regarded as C. bal- 
timorensis Herbst., (repanda Dej.)—LEc. |

Inhabits the southern States. 

Dec. Héad entirely rugose, neck above granulate; clypeus 
narrowed in the middle; labrum much broader in the middle, 
white, edge brown, strongly three-toothed before, of which the 
intermediate one is larger, margin with four punctures, of which 
two are at the lateral angles and the others at the base of the 
lateral teeth ; mandibles white at base, tip black; palpi green. 
Trunk, reddish-purple on the sides; thorax with the lines not 
deeply impressed or differently colored, a little narrowed be- 
hind ; elytra with a slight shade of greenish-olive, convex, with- 
out a sutural angle or spine behind, irregularly punctured with 
green; on the posterior half are some larger, scattered, impress- 
ed green dots, a few at the base and in an undulated line near 
the suture ; surface somewhat unequal, a conspicuous indenta- 
tion towards the base of each near the suture and an oblique, 
abbreviated, obscure one in the centre of the elytron near the 
marginal spot, which is subtriangular, white and placed on the 
middle of the margin; a minute, obsolete, white dot is situate 
at the posterior curve. Abdomen, yenter reddish-purple each 
side near the base; tail black. 

Of this insect I have seen but a single specimen, for 
which I am indebted to Mr. J. Gilliams, who caught it in the 
state of Maryland. It is very possible that it may be a distinct 
species from the C. unipunctata as the figure of that insect by 
Olivier above referred to is rather smaller and of a somewhat 
different habit ; nevertheless as his description agrees very well 
[414] with our insect, J shall consider it as the same until those 
who haye an opportunity of seeing the original may decide.

Desc. Head green, sometimes glossed with blue; antenna, 
four basal joints green, remainder black-brown; labrum white, 
edged with brown, three triangular teeth before, and six margi- 
nal blackish punctures each of which latter furnishes a hair ; 
mandibles white above, tip black; palpi green; eyes brown. 
Trunk green, tinged beneath with blue, but without a cu- 
preous tint, hairs remote and short; feet green; trochanters 
brassy ; intermediate tibia with more numerous short hairs near 
the tip behind ; elytra green, brilliant, behind the middle blu- 
ish-purple, which deepens towards the tip, hind margin rounded, 
obscurely serrate, sutural margin not abbreviated nor mucronate 
at tip, each elytron marked by three marginal white dots, the 
first placed in the middle of the margin, one at the posterior 
curve, and the third transverse and terminal; inferior page 
blackish, marginal spots testaceous. Abdomen, venter bluish- 
green, segments margined, bronzed, edge and tail purple. [415] 

Var. a. Elytra each with an additional spot, which is fulvous 
or white, and generally inconspicuous, placed behind the middle 
triangularly with respect to the two anterior, marginal ones. 

Var. 8. Hach elytron with a single marginal spot, the two 
posterior ones wanting. 

This insect is common in Pennsylvania, but not so frequent 
as either vulgaris or hirticollis. Its characters are strong and 
discriminative, so that our synonymes are free from doubt, al- 
though that of Herbst represents the eyes as white; but this 
color is, as in some of the Carabi and many other insects, only to 
be found in the dried specimen, and is by no means universal. 
The second variety was brought from the banks of the Missouri, 
above the confluence of the river Platte, by Mr. Thomas Nuttall.

bp. /20. 

Length nearly three-fifths of an inch. 

Inhabits New Jersey. 

Desc. Head bronzed, naked, edges green; antennz brown, 
basal joints green, the third hairy before; labrum white, not 
emarginate at the anterior angles, broad before, and furnished 
with a single tooth, eight punctures very near the edge, of which 
six are equidistant on each side of the tooth, the others remote ; 
clypeus almost obsolete above; mandibles white above and be- 
neath, tips and teeth within [416] black-green, a very strong 
tooth beneath, near the tip of one mandible, the other simply a 
little angulated in that part; palpi white, tip of the terminal 
joint of each blackish. Trunk cupreous, covered each side by 
short, dense, prostrate, cinereous hair ; thorax bronzed, varied with 
green, margin and longitudinal dorsal line hairy ; scutel green or 
bronze ; elytra white, with very minute, irregular punctures, and 
afew larger ones on the anterior margin; suture anda lunated branch 
near the scutel, curving on each elytron and abbreviated behind, the 
middle of the base green, disk with two abbreviated green brack- 
et-formed lines, of which one curves outwards and the other in- 
wards, respectively terminating at one end opposite the centre of 
the other. Abdomen, venter bronzed, segments margined with 
purple, having dense, cinereous, prostrate hair each side; tail and 
tip of the last abdominal segments testaceous. 

This very fine and beautiful species I discovered a few years 
ago on the sea beach of New Jersey. In several of the Cicinde- 
lee there is a strong tooth on one of the mandibles near the tip, 
beneath pointing downwards, which is very conspicuous in the 
present species; these teeth are I believe never found on both 
mandibles, otherwise the mouth could not be properly closed, ac- 
cordingly the tip of the armed jaw is always beneath the other 
in repose; neither is the weapon confined to the right or left 
mandible, but is found upon either indifferently, whilst upon the 
corresponding part of the other, is usually a very small angle. 
It must be remarked that this insect seems to approach a species

cupreous, margin pale, uniting the anterior and posterior lunules, 
the former with an accessary spot at the middle of the base, and a 
smaller one interrupted from its tip, the latter continued a short 
distance upon the sutural margin, intermediate band refracted in 
a very acute angle, at the centre of the elytron elongated, and 
dilated behind, terminating at the suture, in a transverse line 
drawn from the tip of the posterior lunule ; trochanters testaceous. 
Abdomen, venter very hairy each side, segments bronzed and 
margined with purple; tail testaceous, of the female blackish- 
purple. [418] 

The markings of the elytra are in many specimens so far obso- 
lete, as to be only distinguishable in a particular light; and they 
are always less obvious than those of the vulgaris, hirticollis, &c., 
to the latter of which, this insect, in the distribution of its bands 
and lunules, bears some resemblance.

This insect is subject to numerous varieties in color and mark- 
ings, but those above described are the most striking of any that 
have fallen under my observation ; the anterior band is sometimes 
obsolete towards the tip, so as to leave a very short perfectly 
transverse line attached to the margin. The variety a, is much 
more common in Pennsylvania than either of the others. It is 
probable that the marginalis of Fabricius will prove to be the 
same with this, but Olivier’s designation, having the right of 
priority, will of course be adopted. The variety 5 is a memora- 
ble departure from the appearance of the species, no trace of the 
original coloring remains upon it, but that of the bands, &c., of 
the elytra ; is seems a link in the connecting chain which unites 
the purpurea with the species described by Fabricius, under the 
trivial name ¢ristis, and seems to be alienated from it, only by the 
presence of an intermediate dot and terminal line; the central re- 
elivate band is precisely the same in form. Nevertheless it is 
highly probable that the ¢rist’s is a distinct species, although for 
the present I have placed it here as a variety, having no oppor- 
tunity of examining a specimen.

anterior marginal dot is always minute, and of all the others 
most frequently wanting, the two anterior spots of the disk also 
are often invisible. Fabricius by mistake refers to fig. 18, tab.

for the C. trifasciata, a native of South America, rather smaller 
than this insect and totally distinct in its characters.

from the band, which is refracted at the centre of the elytron, 
and terminated near the suture, in a transverse line with the 
penultimate spot; this last is large, submarginal, and orbicular ; 
terminal spot transversely triangular, and with the first interrupt- 
ing the margin; sutural angle not mucronate. Abdomen, 
venter bluish-green, with a few hairs each side; tail purple. 

The specimen from which this description was taken is a 
female; it resembles C. purpurea in its differently colored elytral 
margin, but is sufficiently distinct from that insect by its more 
numerous spots, &e. [424]

mology, ante 1, 34, that it is impossible to believe that both have 
been taken from the same specimen. The present figure evi- 
dently belongs to one of the western varieties of C. punctulata, 
but the description does not agree with that species —LEc. ]

Var. a. Elytra destitute of the intermediate band. 

This is the smallest of our species, being less than punctulata, 
and of the most sombre coloring; the lunules and band hardly 
relieved by a contrast with the general surface, as they are very 
narrow. 

The preceding descriptions were drawn out from specimens in 
my possession, the three last species, were caught by [425] 
Mr. Thomas Nuttall on the Missouri, and now form a part of 
his collection ; to him I am indebted for the permission to de- 
scribe them. Specimens of those for which I have referred to 
Melsheimer’s Catalogue, were sent me by the Rey. John Melshei- 
mer of Hanover, a zealous entomologist, and son of the author of 
that work, who may justly be entitled the father of entomology 
in this country. 

In order that the present paper may comprehend all the 
known North American species of this genus, and thereby pre- 
sent a complete Monograph, I subjoin from Fabricius, three de- 
scriptions of species, which have not fallen under my notice ; 
I therefore have taken the liberty to translate his description as 
follows :— 


13. C. viotacEA.—Bright blue polished ; labrum white. 

inhabits Carolina. 

Cabinet of Mr. Bose. 

Desc. Of a medium size; body bright blue, polished, covered 
with elevated scabrous punctures; antennze dark brown at tip ; 
labium (labrum) and base of the mandibles above white. Syst. 
Eleut. part 1, p. 282. 

Is not this referable to the genus Megacephala ? 


14. C. ABDOMINALIS.—Black, labrum and lunule at the apex 
of the elytra white ; abdomen rufous. 

Inhabits Carolina. 

Cabinet of Mr. Bose. 

Desc. Smaller than C. germanica ; head and thorax eylindri- 
cal, black-cupreous, a little polished ; labrum [426] white; ely- 
tra black, an obscure line of impressed punctures at the suture, 


[Vol. I.

and white lunule at tip ; body and feet greenish-brassy, polished ; 
abdomen ferruginons. Syst. Eleut. part 1, p. 237. 


15. C. Mrcans.—Head and thorax cupreous polished; elytra 
obscure ; minute points and lunule at the apex white. 

Inhabits North America. Syst. Eleut. part 1, p. 238. 

It is highly probable that this description was intended to de- 
signate an insect very similar to the C. puactulata, perhaps the 
same, or only a variety of it, for it is as characteristic of that 
species as it can be of any other. 


[From Transactions of the American Philosophical Society, New Series, 
Vol. 2, No.1, 1823.] 


Descriptions of Insects of the Families of CARABICI and HYDROCAN- 
THARI of Latreille, inhabiting Nerth America.* 


Read August 26th, 1819. 


In the first volume of the New Series of the Transactions of 
this Society, I commenced the regular description of our North 
American insects, by a Monograph of the indigenous Cicindelete ; 
a Linnean genus whick occupies the first station in the improved 
classification of Latreille. 

I now proceed to lay before the Society descriptions of such 
of our native insects, as were included by Linné, in his three 
genera, Carabus, Dytiscus, and Gyrinus. The two former of 
these, but more purticularly the first, are nuw considered as great 
families, constituting numerous genera, and agreeably to the or- 
der in which I have enumerated them, immediately succeeding 
the Cicindeletex, in the system which I have adopted. . 


*The title page of the 2d vol. of the New Series of these Transactions 
bears date 1825, which was the time of completion of the volume, but 
the late Dr. T. W. Harris informed mein a letter, that he received from 
Mr. Say a copy of this paper, with the following addition to the title :— 
**Printed and published by Abraham Small, 1823.’ This, of course, 
gives Say’s names precedence of those published by Germar in his Sp. 
Tns. Noy. in 1825.—Lxc. 

1823.) 


436 TRANSACTIONS OF THE 


The Carabit are very numerous, are insectivorous, terrestrial, 
commonly inhabiting moist places, under stones, or [2] fallen 
trees, under bark or on flowers, &c. They generally run briskly 
when disturbed, and many species diffuse a foetid odor, or dis- 
charge a peculiar, pungent, acetous gas. 

The Dytiscti are much less numerous than the preceding, but 
are equally nourished by animal food. They inhabit the waters, 
occasionally visiting the surface for the purpose of respiration ; 
they move with rapidity and ease through the water and the air, 
but on land their gait is embarrassed by the natatory form of the 
posterior feet. 

The Gyrinii, which are now included in the same family with 
the Dytiscii, are comparatively few in number of species, and 
those few are so intimately united in nature by a similarity of 
character and habit, that no division has yet been found neces- 
sary in the genus, which still remains unchanged as it was first 
established in the artificial system. These insects, like those of 
the preceding Linnzan genus, are insectivorous and aquatic ; they 
do not, however, like them, remain at the bottom to seek their 
prey, but chiefly confine themselves to the surface. They de- 
scribe graceful curvatures or gyrations on the surface of the water 
with a pleasing facility of movement, without exhibiting to the 
eye the oar-like feet by which that celerity is effected. When 
alarmed, they dive to the bottom with swiftness, carrying with 
them a globule of air, that their respiration may not be suspend- 
ed. When irritated, they eject a lactescent fluid, which, in 
many instances, diffuses an agreeable odor, somewhat similar to 
that of the Calycanthus floridus of botanists. They fly with 
much ease and chiefly at night, but their moyements on land are 
uncouth and embarrassed. 

After thus briefly noticing the most prominent features exhib- 
ited by these insects, it may be proper to observe, that the de- 
scriptions are drawn out from such specimens only as have fallen 
under my own observation, and which I had an opportunity of 
examining and comparing together, in order the more effectually 
to indicate their differential characters. The individuals are 
chiefly preserved in my cabinet ; and for such as I do not pos- 
sess, I have carefully referred to those collections from which I 


(Vol. IL. 


AMERICAN PHILOSOPHICAL SOCIETY. 4387 


have described them. I have scrupulously [3] retained all the 
specific names, which have been given by the late Rev. F. V. 
Melsheimer, in his Catalogue of the insects of Pennsylvania; ex- 
cepting only such as have been previously employed in the same 
genera by other entomologists ; and so far as I could ascertain 
them by the aid of the scientific intelligence of his son the Rev. 
J. F. Melsheimer, who has liberally furnished me with specimens 
from his collection. I am also indebted to Mr. Thomas Nuttall, 
who has confided to my care his entire collection, with permis- 
sion to avail myself of the opportunity of describing such of them 
as are new. 

I have not thought it necessary to draw out the generic de- 
scriptions at length, as this has already been done with sufficient 
detail by Professor Bonelli of Turin; whose excellent papers I 
have not yet had the good fortune to peruse. If, in the descrip- 
tion of some of the species, I have been anticipated by the labors 
of this, or any author, I shall immediately relinquish my claims, 
and do justice to the real discoverers, when their labors shall 
meet my eye. 

To the inflexible Linnean entomologist, who may object to the 
numerous genera which are here adopted, I will merely observe, 
that each of those divisions which are here called families, he 
may regard as only genera, (as they coincide with those of Lin- 
nzeus,) and to each of the species described he may add the char- 
acters of those divisions which are, in this essay, called genera ; 
thus the system as it stands, complicated as it is by the vast 
accession of discoveries of recent date, will afford him every fa- 
cility, which he might suppose to result from a scrupulous adhe- 
rence to the Linnzean method. 

The modern entomologist will readily perceive that I have not 
adopted all the genera of M. Bonelli, but that many of these are 
included under the genus Feronia of Latreille. In this respect 
I had no option; having no definitions of such genera, with the 
exception of those contained in the Régne Animal, many of 
which are too brief to be exclusively relied upon.

Length, male one-fifth—female one-fourth of an inch. 

Body impunctured and almost destitute of hairs; head black ; 
three basal joints of antenne rufous ; trunk rufous, paler beneath ; 
thorax with an obsolete longitudinal impressed line ; disk some- 
what convex; margin depressed; feet pale; nails pectinated ; 
elytra striated ; striee acute, distant; two large subtriangular or 
suboyate spots near the base ; two smaller ones near the tip; and 
outer edge yellow ; [14] venter pale yellow or reddish-brown. 

Var. a. The two basal spots of the elytra wanting. 

Var. g. Head corrugated. Probably a distinct species. 

This species varies in the form of the basal spots, which are 
sometimes elongated or confluent with the margin, and either ab- 
breviated or attaining the base. The posterior spots also oceur 
enlarged, so as to be confluent with the apical margin. It

strongly resembles Dromius 4-maculatus, but the venter is not 
black, and the spots of the elytra are differently formed. 

On flowers, (the blossom of the blackberry, &c.) in May, June, 
July and August. Not uncommon. 

The name 4-notatus has already been made use of in this 
genus; I have therefore been compelled to change it. 

[The species afterwards described by Dejean as L. analis is 
subsequently claimed as this species, and it is certain that varie- 
ties 2 and 8 are so correctly referred: with regard to the type, 
however, I believe that Say has described LZ. axillaris Dej., thus 
confounding these two very distinct species.—LEc. ]

Very common on flowers. The thorax and elytra, when ex- 
amined by a high magnifier, are granulated.

I found several specimens of this insect in Georgia and Florida. 
It is sufficiently distinct from the preceding ; being smaller, more 
of an oval form, the thorax less contracted at the base, and the 
elytra subsulcate; the lateral edge also is excurved at the base, 
which character distinguishes it at once from the marginatus of 
Fabr. and the sub/evis of Palisot. How closely it may correspond 
with the sulcatus of Macleay I am unable to determine, not having 
yet seen his work. 

I have to regret the circumstance of my not having it in my 
power to refer to M. Palisot de Beauvois’s splendid work on the 
insects of Africaand America. The seventh number only, belong- 
ing to the library of the Philadelphia Museum, has yet met.my 
eye; although I have made several attempts to procure an entire

same figure of Fuess. Arch. the 17th of plate 29, has been refer-

Head black ; antennze and palpi testaceous ; thorax, impressed 
line obsolete, lateral basal lines very distinct, margin somewhat 
depressed, posterior angles rounded, not depressed or punctured 
above ; elytra, striz impunctured, tip obtusely rounded, margi- 
nal punctures continued, edge ferruginous ; feet reddish-brown. 

Not uncommon. Very much resembles the next, but differs 
from it by the more obtuse termination of the body, &c. This 
may possibly be the H. dubius of Palisot, but his description is 
not sufficiently detailed to enable us to determine satisfactorily.

dorsal line obsolete, basal lines subimpressed ; elytra dark green 
or cupreous ; strise impunctured, edge ferruginous, tip acutely 
rounded ; feet pale testaceous. 

I collected this species in North Carolina, where it appears to 
be rather common. It is distinguishable from the preceding 
only by immediate comparison : the tips of the elytra when taken 
together are more acute, the labrum ferruginous, hind thoracic 
angles more acute, feet much paler, and the thorax more dis- 
tinetly transverse. 

[I consider this as probably the species subsequently described 
by Dejean as H. agilis, in which case it belongs to Hurytrichus 
Lec. It may however be Gynandrotarsus harpaloides Ferte, 
an insect from Texas, unknown to me.—LEC. ] 


8. H. vutpecuivs.—Rufous ; elytra brownish, impunctured ; 
posterior thoracic angles rectangular. 

Length nearly two-fifths of an inch. 

Body glabrous, beneath obsoletely punctured; head with the 
mandibles black at tip ; thorax a little contracted behind, base 
each side depressed and punctured, dorsal line obsolete, lateral 
angles rectangular, basal edge rectilinear; scutel dark rufous ; 
elytra blackish-brown, strize profound, impunctured, interstitial 
lines convex, impunctured; pectus and postpectus obsoletely 
punctured ; feet paler. 

This, at first view, resembles Feronia interstitialis. I have but 
a single specimen, which is a female. 

[Subsequently described as H. nigripennis Dej.; belongs to 
Bradycellus.—Lxc. | 

9. H. mrpennts.—Black ; elytra black-blue iridescent; feet 
testaceous. 

Length one-fourth of an inch. 

Body black, beneath dark piceous; antennz, labrum, mouth, 
and feet rufo-testaceous, the latter paler ; thorax somewhat wider 
than long, widest in the middle, hardly narrower at base than at 
tip; lateral edge piceous, [81] almost regularly arquated ; angles 
obtusely rounded ; basal edge rectilinear ; dorsal and basal lines 
obsolete ; base with numerous slight punctures ; elytra blackish, 
with blue and iridescent reflexions. 

[Afterwards described by me as Selenophorus varicolor, having

must therefore now be called H. (S.) opalinus.—Lexc.] 

10. H. vrripis.—Green, beneath black; feet rufous; thorax 
punctured ; elytra with minute hairs. 

Length two-fifths of an inch. 

Head tinged with bronze ; antenne and palpi rufous; labrum 
piceous ; thorax before and at base slightly bronzed; punctures 
numerous, obsolete on the anterior disk; elytra slightly tinged 
with brassy, with acute, impunctured striz, and numerous short 
hairs ; interstitial lines flat ; feet rufous; bears some resemblance 
to Feronia lucublandus. 

[Previously described as H. viridizneus Beauv. and subse- 
quently as H. assimilis Dej.—Lxc. ] 

11. H. nynacis.—Black ; labrum, mouth, and feet testace- 
ous ; abdomen piceous ; base of the thorax narrowed, angles ob- 
tuse. 

Length three-tenths of an inch. 

Body black, beneath piceous ; labrum, mandibles, excepting at 
tip, palpi, three basal joints of the antennze, and feet rufo-testa- 
ceous ; antennz dusky. Thorax of equal diameters, narrower at 
base than the elytra, broadest in the middle ; lateral edge regu- 
larly arquated ; angles very obtuse, posterior edge rectilinear; a 
longitudinal, slightly impressed, continuous line; basal lines 
very distinct. Elytra with a very slight greenish shade; basal 
joint of the anterior and intermediate tarsi dilated and granula- 
ted beneath, the remaining joints hardly dilated. 

The first or basal joint of the anterior and intermediate [32] 
tarsi only is dilated, and it is granulated beneath as in cexnus, 
and of course does not, strictly speaking, belong to this genus. 
The baltimoriensis, carbonarius, agricolus, ceenus, and rusticus 
have also granulations, or rather close set hairs on the dilated 
tarsi of the male. On account of this distinctive character, I 
should have referred them all to that division of Feronia in which 
M. Latreille places Epomis, &c., did not that author expressly 
state that insects of that division ought to have the two anterior 
tarsi only of the male dilated.

FERONIA* Latr. 


From this genus, as defined by Latreille, in the Régne Animal 
I have distinguished Abax, Epomis, Chienius, and Dicelus, as 
distinct genera. [34] 

1. F. Muscunis.—Bedy oval, piceous; thorax at base as 
broad as the elytra. 

Length one-fifth to one-fourth of an inch. 

Body oval, dark piceous or blackish ; beneath piceous ; labrum 
piceous ; antenne and palpi rufous; thorax from the middle to 
the base as broad as the base of the elytra; hind angles subacute 
not depressed ; lateral margin not depressed, but with an elevated 
line; dorsal and basal lines indistinct; elytra striate, striz 
indistinctly punctured, lateral interstitial line serrate before and 
behind on the inner edge; feet rufous or piceous. 

This species I found common on the eastern shore of Virginia, 
in October, on the blossoms of the kinks bush. When caught, 
like very many of the tribe, they diffuse a strong foetid odor. In 
Florida I took several specimens on the wing in a conflagrated 
salt marsh. Belongs to the genus Amara of Bonelli. 

2. F. BASILLARIS.—Oval, blackish-bronzed, beneath black ; 
feet piceous; thorax punctured each side at base, and as broad 
as the elytra; palpi blackish. 

Length three-tenths of an inch. 

Carabus smaragdulus Melsh. Catal. 

Body oval, blackish bronzed or purplish black ; beneath black ; 
antennz deep brown, three basal joints rufous; palpi black ; 
thorax from the middle to the base as broad as the elytra, 
numerous distinct punctures each side at base, posterior angles 
acute, margin not depressed; elytra striate, strie punctured,

marginal interstitial line serrate on the inner edge, margin tinged 
with green; feet deep piceous. [36] 

Closely resembles impuncticollis, but the strive of the elytre 
and the hind angles of the thorax: are punctured. The name 
smaragdulus having been appropriated to a very different insect, 
I have substituted that of basillaris. It belongs to the genus 
Amara of Bonelli. 

[Afterwards described by Dejean as Amara lucidula.—Lxc. | 


3. F. rMpuncricotiis.—Oval, blackish-bronzed, beneath 
black ; thorax impunctured and as broad at base as the elytra ;

basal lines distinct, margin not depressed ; elytra somewhat nar- 
rowed behind with impunctured striz, lateral interstitial line 
serrate on the inner edge; feet piceous black. 

This insect is not uncommon in Pennsylvania; it was also 
found by Mr. Nuttall on the Missouri. Corresponds with the 
characters of the genus Amara of Bonelli. 


4. F. anaustata.—Oval, blackish cupreous, beneath black ; 
feet rufous ; thorax impunctured, as broad as the elytra; palpi 
rufous. 

Length hardly one-fourth of an inch.

broad as the elytra, impunctured, posterior angles acute, margin 
not depressed, dorsal and basal lines distinct; elytra striate, im- 
punctured, marginal interstitial line serrate on the inner edge; 
feet rufous. [37] 

Taken by Mr. Nuttall on the Missouri. Resembles basillaris 
and impuncticollis, but is much smaller, and differs from the first 
by being impunctured, and from the last by the color of the an- 
tenne, palpi, feet, &e. Belongs to the genus Amara of Bonelli.

and otherwise sufficiently distinct. I should have been in doubt 
whether this species or the next was the true pallipes Fabr., had 
it not been for the specific character “ thorax rotundatus” applied 
by that naturalist to his insect, a character more decidedly ap- 
plicable to this species.

The impressed punctures of the intervening lines of the [77]

agree with the description of C. granulatus either as respects the 
color of the antennz or that of the body. And although it 
corresponds with the description of txdatus better than any 
other insect I have yet seen, yet the differences are so striking as 
to forbid its being referred to that species. This will be placed 
beyond a doubt by comparing Olivier’s description with the above, 
and particularly that portion of it relating to the elytra, of which 
he says that they are “ presque lisses ou sans stries bien mar- 
quées, avec trois rangées des points enfoncés.”

Body black, glabrous, depressed ; head with two obsolete pice-

antenn rufous, base paler ; labium elongated, nearly as long as 
the labrum, bisetous near the tip; thorax much abbreviated, as 
broad as the elytra, much contracted behind, exterior and _pos-

conspicuous, posterior angles acute; elytra profoundly striated, 
strize punctured on the sides, interstitial lines convex ; pectus 
and postpectus with obsolete dilated punctures ; feet testaceous: 
venter piceous towards the tip, impunctured. 

In this species the emargina of the anterior tibia is yery small 
and placed very near to the tip, so as to be undiscoverable but 
by particular examination. Judging from the generic definition 
which authors have given, this species must differ from the 
other species of this genus in the form of the labium, which is 
elongated, acute, as in Pogonophorus, and has on each side near 
the tip a long hair or bristle, instead of spines, as in the latter 
genus ; it does not therefore agree with the character given of 
the labium of Nebria,— labium subquadrate,” “ labium short,” 
“nearly quadrate,” &c., nor yet with that of Pogonophorus, of 
which this part is tricuspidate. But as it will not agree with 
any other than the two genera above mentioned, and as it differs 
from the latter genus in not having the mandibles dilated at base, 
nor the maxillary palpi much elongated, I have thought proper to 
place it with the present genus, to which it seems to have the 
closest affinity.

pectus not obviously granulated; sternum acutely carinated ; 
feet piceous; venter with very numerous, oblique, irregular 
lines. 

Var. a. Above dark reddish-brown, margin paler, spots yel- 
low, distinct, piceous ; feet pale rufous. 

My friend Dr. J. F. Melsheimer, in a letter written some 
time since, observes that “the two yellowish macule near 
the apex of the elytra differ oftentimes in depth of coloring 
and in size. I have several specimens that have the macula 
of an irregular, others of an oval or elongated form, and the 
color of all the different shades from a faint yellow to a light 
brown. It delights in miry forest springs, where it feeds on 
tender vegetables and minute insects. If it is caught and 
pressed between the fingers, it will exude from the divisional 
line of the stethidium (truncus) and abdomen, a white milky 
substance. It moves with great activity.” 

It undoubtedly approaches very closely to C. fenestratus of 
Europe, which insect has the same fenestrate elytral spots; as 
well as another insect which is described by Marsham under the 
name of D. obscurus. 

[Belongs to J/ybius, and was afterwards described as Dytiscus 
biguttulus Germ.—L«c. ] 


3. C. AMBIauUS.—Black ; elytra dark reddish-brown; feet 
rufous; body somewhat acute behind; yertex with obsolete 
piceous spots. [97] 

Length not quite seven-twentieths of an inch. 

Body black, above with minute, depressed, irregular granules ; 
head black, two indistinct piceous spots on the vertex and an ab- 
breviated frontal line and puncture each side; antennz and palpi 
pale rufous ; thorax black, dorsal line obsolete ; seutel black; elytra 
dark reddish-brown, immaculate, margin and base paler, apex 
acute; epipleura black; sternum acutely carinated; feet pale 
rufous, posterior ones rufous. 

For this insect I am indebted to my friend Dr. J. F. Melsheimer, 
who sent it to me as a distinct species. It approaches very closely 
to E. erythropterus, but may be distinguished by its smaller size,

4. C. sertatus,—Black, immaculate, slightly purple-bronzed ; 
elytra with about three irregular series of punctures on each ; 
lateral edge of the thorax somewhat rectilinear. 

Length seven-twentieths of an inch. 

Body black; immaculate, above very slightly bronzed, divided 
into very minute, suborbicular, depressed granules, beneath black ; 
head, a transverse frontal puncture each side, with double, parallel, 
obsolete, smaller ones above; antennz and palpi rufous; thorax, 
submargin slightly depressed, dorsal line obsolete, lateral and basal 
edges nearly rectilinear, posterior angles subacute ; elytra on each 
three irregular series of villous punctures, and a submarginal less 
distinct one ; epipleura piceous; sternum acutely carinated, depres- 
sed behind, slightly elevated, obtuse before; feet rufous, posterior 
pair piceous. 

This insect was sent me as distinct by Dr. J. F. Melsheimer. 
It is very closely allied to C. nitidus, but is considerably larger.

viated, central, lateral edge arquated, posterior angles subacute ; 
elytra with three irregular series of villous punctures, and a sub- 
marginal and sutural less distinct one; epipleura black ; sternum 
acutely carinated, depressed behind; feet piceous, anterior ones 
rufous. 

The chief difference between this species and the preceding one 


appears to rest in the general form and size of the body, the color

Body reddish-brown or ferruginous, oblong-oval, with minute 
numerous punctures ; head, lateral frontal line oblique, puncture 
above wanting; thorax, a submarginal slightly rugose line, dorsal

blackish lineated with whitish. [99] 

Length about three-tenths of an inch. 

Body pale rufous, minutely punctured, beneath testaceous tinged 
with reddish, minutely lineated; head blackish at base; antennz 
and palpi testaceous; thorax at the middle of the base and tip 
blackish ; elytra blackish, with very minute, numerous fenestrate

round the humerus, and falcate on the base, an abbreviated sub- 
sutural one at base, hardly attaining the middle, and two or three 
smaller obsolete ones near the marginal line; sternum acutely 
carinated. 

A remarkably handsome and distinct species. It is not common, 
and may probably prove to be the interrogatus of Fabricius.

tures, somewhat irregular, scattered behind, each elytron with a 
pale, fenestrate, elongated, submarginal spot behind the middle, 
and a subtriangular one near the tip ; feet piceous. 

Var. a. Body beneath testaceous; frontal spots obsolete. 

This species approaches very near to fenestralis, but differs in 
having the series of large distinct punctures, in being not more 
than half the size of that insect and more obtuse before. Found 
on Mr. R. Haines’s farm, Germantown.

Dytiscus maculosus Melsh.'Catal. 

Body yellowish-testaceous, glabrous; elytra blackish, three 
spots or dilated lines at base, of which one is humeral and one 
subsutural, each emarginate at tip and profoundly so on the inner 
side, and the third rather shorter, arising from the middle of the

largest, a common irregular spot behind the middle, and an 
apical common band, white, tip obliquely truncate. 

Var. a. Trunk beneath black. 

Var. 6. Yellowish-testaceous ; elytra with a common black

distinct. 

This species I found very numerous in the fresh water marshes

tarsi abbreviated; elytra dark reddish-brown, iridescent, desti- 
tute of punctures or striz, and attenuated behind. 

This seems to be a rare insect; I have seen but a single speci- 
men. This new genus certainly differs from all the genera of 
its family by the form of the labial palpi, of the sternum and 
poststernum, mucronate anterior tibia, &e. It closely approaches 
the genus Noterus by the dilated labial [106] palpi, but differs 
in having those parts entire.. It also has some relation to Hali- 
plus by the scales which conceal the origin of the posterior feet. 
The proper situation of this new genus is between those two 
genera, but it is unquestionably much more closely allied to the 
former.

1, 2, the anterior one before the middle, the two succeeding ones

The Dytiscus maculatus of Fabricius is altogether different from 
this species; it is a Colymbetes. I have, however, thought 
proper to reject the name maculatus as applied to this insect, 
lest it should be confounded with the Fabrician insect by those 
who adhere to his system or to that of Linné.

four or five obsolete striz, tip distinctly and very obtusely 
sinuated, a projecting angle at the sutural tip; poststernum with

angle or obtuse spine near the tip of the anterior edge of the 
thigh. 

The elytra appear emarginated at the tip of the suture when 
at rest, in consequence of each of them haying a rounded termi- 
nation. This species must have hitherto been confounded 
with the Americanus with which it associates indiscriminately, 
but is sufficiently distinct by the armature of the anterior femora

This insect, which I found near the Rocky Mountains, I de-

mutilated state of the specimen it seems to agree better with the 
Megacephala. It differs from Manticora altogether in form, in 
the smaller size of the head, and in not having a lobed thorax, Xc., 
but it corresponds in the comparative magnitude of the eyes, the 
diameter of which is hardly more considerable than that of the

basal joint of the antennz. In the size of the eyes it differs 
greatly from Megacephala, also in the circumstance that the 
basal joint of its labial palpi is altogether concealed by the men- 
tum : but it agrees with this genus in form, and is probably [410] 
more closely related to it than Manticora. Still, however, as it 
does not agree with any known group, it may perhaps be proper 
to construct a genus for its reception.

State. 

Of this genus I have in my cabinet twenty-two species, natives 
of the United States, that have been described. 


ARETHAREA Say. 

Artificial character.—Elytra truncated ; terminal joint of the 
maxillary palpi acicular; anterior tibie simple. 

Natural Character.—Head large, wider than the thorax, con- 
tracted behind at the junction with the thorax; antenne origi- 
nating beneath a carina, with the first joint much shorter than 
the head; labrum short, bilobated ; the lobes divaricated ; margin 
hairy ; mandibles very prominent, arquated, acute ; within promi- 
nently and acutely denticulated ; maxille rectilinear with rigid 
hairs within; palpi with the penultimate joint dilated ; ultimate 
joint acicular and minute ; labium at tip with two equal mem- 
branaceous lobes and a lateral robust seta; palpi very small and 
feeble, terminal joint somewhat shorter and more slender than 
the preceding one; mentum transverse, simple; destitute of 
auricles; thorax cylindrical; truncate before and behind; elytra 
broadly truncate at tip; tibize, anterior pair simple; tarsi with 
subequal simple joints; the basal ones slightly longest ; nails un- 
armed ; posterior pair of feet with the nails pectinated. 

Obs. The prominent, arquated and denticulated mandibles of 
this curious insect resemble, with some accuracy, those of Cicin- 
dela ; but the general appearance and extraordinary assemblage 
of characters widely separate it. It has the truncated elytra of 
Lebia and its congeners; the simple anterior tibiz of Cicindela ; 
and a singular character that seems to connect the two families, 
that of having the anterior pair of nails simple and the posterior 
pair pectinated. We may also remark, however, that the acicu-

lar terminal joint of the maxillary palpi is a trait in common with 
Bembidium Bon. 


A. HELLUONIS.—Head black ; thorax rufous ; elytra blue. 

Inhabits Pennsylvania. 

Head punctured, somewhat hairy; eyes small, almost equidis- 
tant [412] between the tip of the mandibles and the thorax ; an- 
tenne, first and second joints pale rufous; labrum yellowish-ru- 
fous; mandibles piceous; palpi pale yellowish rufous; thorax 
punctured, excepting along the dorsal middle; elytra destitute 
of striz or punctures, blue, with a purplish reflection; feet and 
postpectus pale yellowish; knees and tarsi brownish. 

Length three-tenths of an inch. 

The intermediate feet and the antenne, excepting the first and 
second joints, are deficient in this specimen. I am not sure 
whether [ obtained it on our journey to the Rocky Mountains, 
to St. Peter’s river, or in Pennsylvania, but I think the latter. 

[No insect has yet been seen by other entomologists, which at 
all approaches the description here given. With regard to the 
systematic relations which such an object would have, it is quite 
obvious that it should not be placed with the Carabide, since 
the mentum transverse, simple, destitute of auricles, is altogether 
foreign to the Adephagous series. This form of mentum, with the 
subulate palpi and bilobate labrum, fix the head, at least, as be- 
longing to a Staphylinide. In that family the insertion of the 
antennze, form of palpi, ligula and mandibles, prove conclusively 
that it enters the group Pederini. In fact, there is nothing in 
the description of the head, thorax and anterior legs, which for- 
bids a reference to Cryptobium bicolor or C. melanocephalum. 
With regard to the elytra and posterior legs, I must suppose them 
to have been derived from some foreign Carabide, and that the 
union was effected unintentionally, before the specimen came 
under Say’s notice.—LEc. ] " 


CASNONTA Latr. 

C. RurreEes Dej.—The insect of this genus represented by 
Drury (Ins. 1, pl. 42, f. 4 and 6) is probably a variety of this 
species. Dejean has not noticed this figure at all. The Galerita 
americana is represented in the same plate.

Elytra entire; tibia emarginate; terminal joint of the tarsi 
profoundly bilobated ; nails simple ; head as long behind the eyes 
as before them; thorax subcylindric; antenne much shorter 
than the body; basal joint much shorter than the head, 
joints excepting the second not very unequal in length, subcy- 
lindric ; labrum emarginate ; palpi with the terminal joint some- 
what fusiform, subacute; mentum with a prominent acute cen- 
tral tooth.

polished, broader than the thorax; thorax cylindrical, obscurely 
ferruginous; elytra striate, testaceous; suture broadly black, 
hardly attaining the tip ; body black ; feet testaceous.” abr. 

Odacantha dorsalis Fabr. Syst. Eleuth. 1, 229. 

In my specimen the head only is black, or rather of so deep a 
rufous as to appear black, excepting the tip and base. [413] 

This well known species was referred by its discoverer, Fabri- 
cius, to his genus Odacantha ; in which arrangement he was.fol- 
lowed by Dejean, who, however, was fully aware of its generic 
difference from the O. melanura, Fabr. Dejean, in his observa- 
tions on the genus, says, “that in consequence of the joints of 
the tarsi being less filiform than those of the type of the genus, 
almost triangular, the penultimate one deeply bilobate and the 
extremities of the elytra rounded, it would be perhaps proper to 
make a new genus of this insect.” In this remark I perfectly 
coincide, as I cannot see the propriety of joining, in the same 
genus, two insects whose characters in the artificial system place 
them in different families, though it cannot be denied that they 
have many, more intimate, natural affinities. 

I had written the above with the expectation of introducing 
a new species, in an insect which, in form and color, resembles 
the dorsalis exceedingly to the eye, excepting in size; but on 
close examination it proves to be widely distinct.

1. C. piaticoniis Say, (Lebia) Trans. Amer. Philos. Soe. 
vol. 2, new series. 

This species has been since described by Dejean under the 
name of C. complanata. In my specimens the palpi are hardly 
dilated. It varies in having the thorax darker and of the color 
of the head. I obtained an individual in Indiana. 


2. ©. LATICOLLIS.—Blackish ; thorax transverse; feet pale 
rufous; elytra with slender strie and minute punctures. 

Inhabits near the Rocky Mountains. 

Body black-brown, punctured, with short hairs : head ; 
thorax decidedly transverse, with numerous somewhat large punc- 
tures ; truncate before, and a little sinuate behind; margin each 
side depressed and a little elevated, dull rufous ; at the posterior 
an obvious tooth; elytra with very slender capillary strie im 
which are minute punctures, which are larger and more obvious 
towards the base and lateral margin; interstitial lines with a 
very slight convexity, and with numerous small punctures, rather 
larger than those of the strie ; lateral margin [414] obscure 
rufous; tip truncate, without any appearance of sinuation: be- 
neath obscure rufous, punctured ; feet rufous; thighs and _ tro- 


chanters paler. 

Length about two-fifths of an inch. 

I obtained it when on the expedition to the Rocky Mountains 
with Major Long. The thorax is shaped somewhat like that of 
americana, Dej., but is wider, as in platicollis, Say. The elytra 
have not the slightest appearance of being sinuated at tip.

slight ; lineations near the eyes: antennze brownish blue, first and 
second joints ferruginous: thorax with minute, irregular, transverse 
lines, dorsal lines well impressed: elytra slightly grooved, more

Var. a. Sutural edge of the elytra ferruginous. 

I obtained this species in the winter of 1819, when with Major 
Long’s party, at Engineer Cantonment, near Council Bluff. It 
occurred in considerable numbers, occupying some crevices of 
rock, eight or ten feet under the surface, in a temporary quarry, 
where they were hybernating. It differs from cyanipennis, Say, 
found at the same locality, by the different color of the antennze, &c. 

Can this be the janus, or is the guadripennis De}. synonymous 
with that species described in Turton’s Linn. ? 


CLIVINA Latr., Dej. 


1. C. prpustuLATA Fabr.—The true species of this author 
has almost always, if not in every instance, but two spots on the 
elytra, and these are terminal. The second interstitial line has 
seven or eight subequidistant punctures, and the fourth interstitial 
line has five or six punctures, subequal, excepting the terminal 
one, which is more distant. 

2. C. QUADRIMACULATA Palisot de Beauvois.—This species is 
quite distinct, though very closely allied to the bipustulata. It is 
similar in size and almost so in form; but the thorax is propor- 
tionally longer. In color it is generally like the preceding, but in 
addition to the two terminal punctures of the elytra, their base is 
more or less, but generally obsoletely, tinged with obscure rufous. 
The interstitial lines are [416] altogether destitute of punctures. 
I have a variety in my collection, of which the elytra are entirely 
of a rufous color and even paler than the terminal spots usually 
appear; these spots are of course not visible. 

3. C. viripis Say, Trans. Amer. Philos. Soc., has been since 
described by Dejean under the name of rostrata, Sp. Gen. 1, 
419, but corrected vol. 2, Supp. 478. 

Of this genus I have eight described species of this country. 


CARABUS Linn. 
1..C. vinctus Weber.—I think it highly probable that Dejean 
is right in considering, as he does, (doubtfully however), my C. 
interruptus to be the same as this. Weber's expression, “ lineis 
elevatis tribus,” renders this conclusion highly probable. 
[Vol. IV. 


AMERICAN PHILOSOPHICAL SOCIETY. 529 


2. C. Ligatus Germar, Sp. Nove, p. 6.—Since described by 
Dejean under the name of carinatus, Sp. Gen. 2, 80. He quotes 
igatus doubtfully as synonymous. His description, however, 
agrees so perfectly that I feel no hesitation in considering them 
the same. 


3. C. SERRATUS Say, Trans. Amer. Philos. Soc.—Since de- 
scribed by Dejean under the name of lineato-punctatus, Sp. Gen. 
2, 77; the former has, of course, the priority. 


4. C. ExTERNUS Say, Jour. Acad. Nat. Sce.—The largest 
American species I have seen. It belongs to Dejean’s twelfth 
division of this numerous genus. What is the C. tedatus L.? 


CALOSOMA Weber.

2. C. LaVE Dej., Sp. Gen. 2, 210.—I obtained an individual 
of this insect in Mexico. It corresponds accurately with the 
description ; but in addition I may add that it varies in having a 
large obscure rufous spot on the vertex. 


3. C. cALIDUM Fabr.—My description in the Trans. Amer. 
Philos. Soc. was taken from the true Fabrician species as is evinced 
by the expression “ dilated, impressed, golden dots,” as applied to 
the elytral [417] excavations. But I did not sufficiently examine 
the very closely allied species which Dejean has separated from it, 
as I supposed it to be only a variety. 


ELAPHRUS. 


1. E. ruticrnosus.—This new species was found in Pennsyl- 
vania by Mr. Le Sueur, to whom J am indebted for the specimen ; 
and although the head and thorax are destroyed, yet sufficient 
character remains to prove it the analogue of the L£. wliginosus, 
Fabr., of Europe. In comparison with that species, however, 
many dissimilarities are perceptible. The discoidal indentations 
are larger and more obviously emarginated by the entering an- 
gles of the interstitial spaces. The interstitial spaces are some- 
what less regular, and have rather large punctures, particularly 
towards the base; towards the tips of the elytra the punctures 
are not larger than those of the wliginosus, but are fewer in num- 


1834.] 34 


530 TRANSACTIONS OF THE 


ber. The body is slightly larger than in that species. It ap- 
pears to be rare. 
[This is perhaps L. cicatricosus Lee.—Lxc.] 


2. E. ruscarius.—This species I described in the Trans. 
Amer. Philos. Soc., with a mark of doubt, as the £. riparius 
Fabr., but having recently compared it more accurately with nu- 
merous European specimens, I think it may, with propriety, con- 
stitute a distinct, but certainly very closely allied species. In 
comparison with the ripardus, it is rather more robust, ofa darker 
color, more deeply sculptured, as well on the thorax as on the 
elytra, and the discoidal impressions are somewhat larger and 
more obvious. 

In these characters my specimens allagree, and I possess more 
or less mutilated specimens from Pennsylvania, Mississippi, Ar- 
kansaw, Missouri and the Rocky Mountains. I therefore have 
ventured to separate it as a distinct species. 


NOTIOPHILUS Dumer. 


1. N. sEMIsTRIATUS, Say.—Closely allied to V. aquaticus F., 
and biguttatus F., partaking of the characters of both. Dejean 
states that it “ne différe peut-étre pas de l’une des espéces 
d’Europe,” but he does not inform us which of the species ; in- 
deed they are all so closely [418] allied, that considerable exam- 
ination is required to detect permanent differences. The elytral 
puncture is small, and like that of aqguaticus, placed nearer the 
base than that of the biguttatus, but the striz like those of the 
latter, are not obsolete towards the tip; the four basal joints of 
the antenne are rufous, Xe. 


2. N. porrectus Say.—W. semistriatus, var. b, Say. Trans. 
Amer. Philos. Soc. On close examination I am convinced that 
this deserves to rank as a separate species. In comparison with 
either of the species above mentioned, the thorax is much more 
contracted behind, and the labrum is more advanced. The feet 
are entirely rufous, even including the thighs. The head is 
larger than that of the sem/istriatus, and the strie are not so deep- 
ly impressed, but the impressed point of the elytra is similarly 
situated, though perhaps a little further back. The length is 
much the same. The color is tinged with violaceous.

ly punctured, sparse near the anterior angles, and almost want- 
ing each side of the middle; dorsal line acute, almost obsolete ; 
basal lines widely indented ; lateral edge regularly arquated ; 
dull rufous; basal edge rectilinear in the middle and a little ob-

with profound, obsoletely punctured striz; interstitial spaces 
flattened, punctuated, [419] sericeous ; rather dull green with a

tions between the antennze, and an obsolete transverse one be- 
tween the eyes; antenne pubescent, blackish, three basal joints 
dark piceous ; palpi piceous ; thorax short ; lateral margin regu- 
larly arquated ; posterior angles rounded ; impressed lines dilated ; 
elytra with punctured strix ; interstitial spaces minutely granu- 
lated, depressed ; beneath blackish ; feet rufo-ferruginous, joints 
and tarsi blackish-piceous. 

Length nearly half an inch. 

Resembles vigilans Nob., but the thorax is shorter and the

lique; region of the posterior angles a little, but widely, depressed, 
rufous or sanguineous, and by transmitted light it appears reti- 
culated; impunctured; posterior angles rounded, but not ob- 
tusely so; greatest width a little behind the midle ; elytra with 
the strize continued parallel to the tip, well impressed, minutely 
punctured; interstitial spaces depressed, third with a single 
slight puncture en the posterior fifth from the base ; beneath 
black ; posterier angles of the pectus, epipleura and feet piceous ; 
anterior tarsi with four not widely dilated subquadrate joints, the 
fourth joint being as large as the third, and all beneath with 
dense fastigiate hairs; intermediate tarsi also somewhat dilated. 

Length less than two-fifths of an inch. 

The elytra are hardly perceptibly sinuous near the tip. 

The specimen, for which I am indebted to Mr. J. Barabino of 
New Orleans, is a doubtful congener of the O. helopoides Fabr., 
than which the body is somewhat more elongated, the thorax 
more gradually narrowed before. It has at first sight more the 
appearance of the Harpalus terminataus or Calathus gregartus Say. 
The intermediate tarsi are somewhat dilated, the anterior tarsi 
are not widely dilated and the terminal joint is as large as the 
preceding one. I place it in this genus provisionally, more speci- 
mens may show this arrangement to be incorrect. The parallel- 
ism of the striz of the elytra to their termination is a remarka- 
ble character, even more obvious than in the helopoides.

This species is rather more robust in proportion to its length

Length nearly seven-twentieths of an inch. 

Size of A. viduum Fabr., with the similar punctures on the 
third interstitial line, excepting that they are equidistant, and 
these lines are more convex, the thorax is much more orbicular, 
the feet differently colored, and there is no brassy reflection. 
This cannot be the melanarium Dej., for the striz are as obvious 
as in the viduum, and although the thorax agrees with that 
insect in being “plus etroit” than that of the vidwum, yet it 
would not be described as “ subrotundato,” as that author ap- 
plies the same term to designate the form of the thorax of viduum. 
It is much like A. punctiforme Say, but it is a little more elon- 
gated, the thoracic lines are much less distinct, &c.

Inhabits Pennsylvania. 

Body blackish ; head impunctured ; antennse dusky, pale rufous 
at base; palpi piceous ; thorax with the dorsal and anterior lines 
almost obsolete ; lateral narrow margin obviously rufous ; lateral 
basal impressions very distinct, suborbicular and sparsely punc-

Sreropus Meg. 


2. F. opsoLETA.—Blackish-ferruginous ; elytra, strie obsolete 
each side and at tip. 

Inhabits Indiana. 

Body very dark rufous, polished; labrum, palpi, mandibles at 
base, antenne, feet and abdomen honey-yellow; head impunc-_ 
tured ; a slightly raised line over the antenne, inside of which the 
front is slightly corrugated transversely each side; thorax with 
the surface obsoletely corrugated, visible in a particular direc- 
tion ; dorsal line acute, slightly impressed ; basal lines indented, 
single, viewed from above orbicular, definitely and rather deeply

impressed ; base a little emarginate, not wider than the abdomi- 
nal petiole ; elytra with punctured, not deeply impressed strize, 
obsolete at tip and on each side; marginal ocellate punctures 
about seventeen, in a continuous series rather sparse in the mid- 
dle : near the tip very slightly sinuated ; third interstitial space 
with a puncture [425] near the middle of the second stria. 

Length two-fifths of an inch. 

Closely allied to S. Uigeri Panz., but the thorax of that spe- 
cies is not so narrow at base, and its elytral striz are not obsolete 
at tip, and not even decidedly so on the sides. It is excedingly 
like S. ventralis N., but it is more robust, and the sides of the 
elytra are more arquated. 

The characters of this species agree very well with the descrip- 
tion of tencbricosa Dej., excepting that the elytra are not “assez 
fortement sinuées postérieurement.” 

3. F. opscurA.—Black ; tibiee and tarsi dark rufous; elytral 
strize obsolete on each side. 

Inhabits Indiana. 

Body black ; labrum and base of mandibles tinged with rufous ; 
palpi dull honey-yellow ; antenne blackish ferruginous ; front 
with two indented lines; head impunctured ; thorax not so nar- 
row at base as the petiole; dorsal line acute, not deeply im- 
pressed; basal lines well indented, definite, impunctured, not or- 
bicular, viewed in any direction, very slightly arquated ; elytra 
striate ; the striz not distinctly punctured, obsolete on the lateral 
submargin, and not so obvious at tip as on the disk; marginal 
ocellated punctures about seventeen ; near the tip rather slightly 
sinuate ; third interstitial tripunctured, the two anterior punc- 
tures at the third stria. 

Length less than nine-twentieths of an inch. 

Resembles the preceding, but the thorax at base is wider, and 
the body is longer. In the proportion of the base of the thorax 
it corresponds with F. J/ligeri Panz., but aside from color, it may 
be distinguished from the obsolete lateral strize, the much less 
dilated thoracice basal lines, Xe.

PLATYSMA Sturm. Dej. 

4. I. opLonconoraTa.—Dark reddish-ferruginous; elytra 
with five or six large subsutural punctures. 

Inhabits North West Territory. 

Body with a hardly perceptible metallic gloss; head darker ; 
thorax with the dorsal line very distinct ; lateral basal lines well 
indented and with obsolete confluent punctures ; posterior angles 
angulated ; elytra striated; five or six large indented punctures 
placed somewhat [426] alternately on the second and third 
strie ; marginal ocellate punctures with their regions indented. 

Length nine-twentieths of an inch. 

This is the analogue of the F. oblongopunctata ¥., correspond- 
ing in the punctures of the elytra, but differing in color, and 
having the thorax somewhat more robust. 

5. F. pepARCA.—Reddish-brown ; thorax punctured on the 
anterior and postérior margins. 

Inhabits Mexico. 

Body reddish-brown, rather pale; head much darker, tinged 
with blackish, impunctured; antennz short, not reaching the 
base of the thorax ; thorax rather abruptly contracted behind ; 
anterior and posterior margins deeply punctured, the punctures 
of the former not extending to the lateral margin; lateral mar- 
gin with a puncture furnishing a hair on the middle and another 
on the posterior angles, which are rectangular ; dorsal line dis- 
tinct, but not deeply impressed; basal impressions dilated, and 
with all the base punctured ; elytra with slender striz, not deeply 
impressed, but with very distinct punctures; stria obsolete to- 
wards the tip; epipleura and all beneath paler. 

Length nearly half an inch. 

The light color, with the punctured anterior and posterior 
thoracic margins, will distinguish this species. 

It was taken by William Bennett and presented to me by Mr. 
Maclure.

agrees perfectly with his description, but as the palpi of my only 
remaining specimen are deficient, I cannot be certain of its ge- 
neric identity. 

7. F. [A.] permunpa.—Black, with a perlaceous reflection ; 
third interstitial line three-punctured. 

Inhabits Indiana. 

Body black; antennz piceous, dull honey-yellow towards the 
tip; distinctly compressed; joints, in profile a little narrowed to 
the base ; palpi piceous, not at all securiform, terminal joint less 
dilated at tip than that of the preceding joint; thorax with a 
slight perlaceous reflection, rather narrower at tip than at base ; 
lateral margin depressed, [427] punctured, gradually reflected 
to the edge, which is but little arquated ; posterior angles rect- 
angular ; disk impunctured ; dorsal line well indented ; basal lines 
two on each side, punctured within, deeply impressed, the ex-. 
terior one very short; elytra brownish-black, somewhat irides- 
cently pearlaceous; striz deeply indented, impunctured ; scutel- 
lar striae short, but definite; interstitial spaces convex ; third 
three-punctured, first puncture near the base on the third stria, 
second on the middle on the second stria, third towards the tip, 
also on the second stria; beneath piceous ; sides very distinctly 
and numerously punctured. 

Length half an inch. 

I obtained this fine species a few days since under an old log. 
It does not at all agree with either of the descriptions of Dejean. 
The labrum is not emarginate. The terminal joint of the palpi 
is less dilated towards the tip than that of the A. parallelus 
Duftschm., or A. metallicus Fabr.

obtusely sinuous ; tarsi dull rufous. 

Length less than two-fifths of an inch. 

Taken by William Bennett, during his stay in Mexico with 
Mr. Maclure. 

It will be obvious from this description, that our species does 
not well correspond with the S. pumicatus, Panz., but agreeably 
to the tables given by Dejean it cannot be placed elsewhere. It 
is larger and more dilated than pumicatus, the basal joint of the 
antenne is shorter, the palpi are not so obtusely truncated, and 
its habit and appearance quite different.

In my paper on the Curabiciand Hydrocanthari, published in 
the Trans. Amer. Philos. Soc. vol. 2, new series, as above quoted, 
I described five species of the United States, under the genus 
Feronia, agreeably to the arrangement of Latreille, indicating, 
however, at the same time, that they belonged to Bonelli’s Amara. 
But Dejean and many other distinguished entomologists give the 
group a separate station.

The following species appear to be new: [429] 

7. A. potosa.—Black ; oblique line near the thoracic angle 
obviously impressed ; elytra vias impunctured striz. 

Inhabits Mexico. 

Body black, impunctured ; head with the impressed lines be- 
tween the antenne absolete ; antennze fuscous, joints rather short, 
three basal joints honey-yellow ; palpi black piceous, thorax rather 
short, lines not deeply impressed ; oblique line near the posterior 
angles very distinct; hair of the lateral margin situated at one- 
third of the distance between the anterior and posterior angles, 
another hair at the basal angle ; elytra with impunctured capillary 
striee; interstitial lines depressed, hardly convex; feet piceous- 
black ; tibize and tarsi a little paler. 

Length nearly three-tenths of an inch. 

Resembles A. impuncticollis, nob., and A. communis and vul- 
garis Fabr., but differs from all in color, greater brevity of the 
thorax, more robust form, &c. Viewed in a particular light, a 
tint of blue may be, with some difficulty, detected. 


8. A. seRA.—Greenish black ; three basal joints of the anten- 


ne yellowish. 


Inhabits Mexico. 
Antenne fuscous; first, second, third and base of the fourth 


joints yellowish ; thorax impunctured, basal angles rectangular, 
with the oblique line not deeply impressed ; basal lines rather 
deep, abbreviated, definite, impunctured; dorsal line distinct ; 
elytra with the striz impunctured, acutely impressed ; basal ab- 
breviated striz rather long ; interstitial lines with a very slight

convexity, nearly flat; near the lateral tip slightly and rather 
acutely sinuated ; tibie and tarsi-piceous. 

Length three-tenths of an inch. 

The thorax is longer than that of the preceding species, and 
the interstitial lines are a little convex, which will readily dis- 
tinguish it from A. impuncticollis, N. The colors of the antennx 
as strongly contrast as those of A. vulgaris F. 

9. A. FURTIVA.—Pale ; thorax punctured at base ; elytra with 
punctured strize. 

Inhabits Indiana. 

Body honey-yellow, more or less tinged with dusky; antenna, 
palpi and all beneath paler; head with the frontal impressed 
lines dilated, distinct; thorax a little contracted at base, the 
posterior angles slightly excurved and acute ; dorsal line well 
impressed, particularly behind the [430] middle; basal lines 
deeply impressed and definite, punctured ; impressed lines of the 
posterior angles, distinct and rather deep, punctured ; base pune- 
tured ; elytra with punctured strie ; the punctures orbicular and 
close set ; near the tip obtusely, but not deeply sinuated. 

Length less than two-fifths of an inch. 

Resembles the A. fulva, Ill., particularly in the form of the 
thorax. The color has sometimes a very slight metallic tinge, 
but never so obvious as in the fulva. 


10. A.? agrossa.—Alternate interstitial spaces punctured. 

Inhabits N. W. Territory. 

Body short, robust, convex, blackish piceous; head ; 
thorax convex, descending much each side, transverse, oblong- 
quadrate ; dorsal line almost obsolete ; anterior transverse line 
hardly obvious; basal margin depressed and somewhat rough ; 
lateral margin depressed, but not elevated except near the poste- 
rior angles lightly ; elytra with a sinus near the tip; stria well 
impressed, impunctured ; interstitial spaces with from five to 
eight distinct punctures on the third, fifth and seventh spaces ; 
marginal series of punctures small, almost indistinct. 

Length of thorax and abdomen nine-twenticths of an inch. 

This species I found in the north western part of the United 

. States when traversing that country with Major Long’s party. 
It is a remarkable insect, readily distinguishable by the peculiar

Body black, impunctured ; antennz not reaching the base of 
the thorax; first joint pale testaceous, second joint darker, re- 
maining joints blackish; impressed frontal lines very distinct ; 
thorax without any appearance of puncture, not narrowed behind ; 
lateral edge regularly arquated ; posterior angles rounded ; dorsal 
line not very obvious ; basal indentations much dilated, not pro-

obtusely sinuous; abdomen, terminal and anal segments above

is perhaps still more like that of an Amara in being more obtuse 
and robust. It is much larger and more rounded behind. It

anterior pairs of the tarsi of the male are clothed with dense 
hairs beneath. 


6. H. amputatrus.—Elytra greenish, truncate at tip. 

Inhabits N. W. Territory. 

Body blackish ; head with the frontal lines rather slightly 
indented ; antennze, palpi, tibize and tarsi honey-yellow, the tibize 
darkest; thorax with the basal angles rounded; edge obscure 
rufous; dorsal line [433] obsolete, or slightly impressed; basal 
lines substituted by dilated, slightly indented spaces, in which are 
numerous small punctures; posterior lateral margin with smal] 
punctures; basal margin obsoletely tinted with greenish ; elytra 
with impunctured striz, more or less green, sometimes bright 
green; suture, outer and terminal edges obscure rufous; tip 
widely and somewhat obliquely truncate. 

Length less than two-fifths of an inch. 

Var. a. Elytra reddish brown, with hardly any tint of green. 

Readily distinguished by the truncated appearance of the tip 
of the elytra, from H. zneus F., which has the elytra decidedly 
sinuate at tip, and even abruptly so. 


7. H. ocreatus.—Black green ; impunctured ; feet pale yel- 
lowish. 
Inhabits Mexico. 
[Vol. IV 


AMERICAN PHILOSOPHICAL SOCIETY. 547 


Body very dark green, impunctured ; head black, with hardly 
any appearance of green ; antenne honey-yellow, the joints, ex- 
cepting the first and second, with darker centres ; palpi and base 
of the mandibles honey-yellow ; labrum with a slight projecting 
angle in the middle of the emargination ; thorax blackish green, 
hardly narrower at base ; dorsal line indistinct, but more obvious 
in the middle ; basal indentations dilated not profound ; lateral 
edge dull honey-yellow ; posterior angles obtuse ; elytra obviously 
tinged with green ; a little wider at base than the thorax; strie 
very slender, impunctured ; interstitial spaces flat, third space 
with a puncture at three-fourths the length from the base ; lateral 
edge near the tip and suture near the tip obscurely piceous ; tip 
deeply and rather obtusely sinuous; beneath black, the greenish 
tinge hardly perceptible; feet yellowish; tarsi rather darker ; 
first joint of the anteriors of the male somewhat smaller than the 
second ; these tarsi have beneath close set hairs. 

Length over seven-twentieths of an inch. 

This species has almost the Amara like form of some species 
of Anisodactylus, in which genus I should have placed the spe- 
cies but for the angle in the emargination of the mentum. It is 
very closely allied to terminatus Say, but is rather more robust, 
the head and thorax are differently colored, the posterior lateral 
margin is more depressed, &c. [434] It must resemble closely 
H. agilis Dej., of which it may possibly be a variety. 

It was obtained by William Bennett, and presented to me by 
Mr. Maclure. 


STENOLOPHUS Meg., Dej. 


S. crnctus.—Dark piceous; margin and suture of the elytra

Inhabits Massachusetts. 

Body blackish piceous ; antenne fuscous, three basal joinis 
and labrum honey-yellow ; mandibles piceous, black at tip; tho- 
rax rather convex, a little narrowed behind gradually ; base rec- 
tilinear, each side a little arquated to the posterior angles, which 
are obvious but almost rounded; lateral edge but slightly 
arquated, nearly rectilinear behind the middle, near the posterior 
angle hardly perceptibly excurved; dorsal line very distinct

anterior transverse line distinct, obtusely arquated; basal lines 
so much dilated as to extend to the lateral angle, including a 
few sparse, profound punctures ; base and tip and exterior edge 
paler piceous; elytra with impunctured, deeply indented striz, 
less profound towards the margin; rudimental strie none ; sutural 
interstitial space paler piceous; dilated exterior margin honey- 
yellow ; lateral series of punctures, with the exception of a small 
one, widely interrupted in the middle; feet pale yellow. 

Length less than three-twentieths of an inch. 

For this insect [am indebted to Dr. Harris. On a cursory 
examination I considered it identical with S. ochropezus Say, 
notwithstanding its great inferiority of size, which may at once 
distinguish it. The thoracic posterior angles are much more ob- 
tusely rounded in that species, the punctures of the basal lines 
are much more numerous and extend nearly to the basal middle, 
the dorsal line is obsolete, &e.

at present restricted. 

2. B. HonestuM Say, Trans. Amer. Philos. Soec.—When de- 
seribing this species I stated that the elytral strie are “not ob- 
solete behind.” This may be corrected by substituting the phrase 
“almost obsolete behind.’ The punctures of the strie are large 
and obvious at base, but are obsolete, or rather entirely wanting 
on the posterior third. The exterior margin and epipleura are 
blackish green. 

3. b. PUNCTATOSTRIATUM Say, Trans. Amer. Philos. Soc.— 
The posterior angles of the thorax are very acute; the basal and 
anterior margins are slightly longitudinally wrinkled, the dorsal 
line transversely wrinkled on its margins, and the basal lines are 
obliquely wrinkled; the sides of the thorax are also somewhat 
undulatedly wrinkled. The third interstitial space is much wider 
than the others, and the posterior punctures is much nearer to 
the anterior puncture than to the tips. 


4. B. Lavicatum Say, Trans. Amer. Philos. Soc.—The basal 
thoracic lines are much dilated. 


d. B. coxenprx Say, Journ. Acad. Nat. Se. 3, 151.—An- 
tennee with three basal joints and base of the fourth pale yellow- 
ish ; palpi (in the dry state) pale yellowish, dusky at tip; face 
with an impressed line each side; vertex longitudinally wrinkled ; 
surface somewhat wrinkled transversely and at base longitudi- 
nally ; basal indentations dilated, minutely rugose; elytra with 
the anterior and posterior discs obscurely testaceous. I am not 
so fortunate as to possess definitions of the several genera into 
which this genus, as originally constructed by Latreille, has been 
recently divided; but I rather think, by analogy, that the pre- 
sent species is a Peryphus Mee. ‘ 

[This variety, if it be so, was previously described by Dejean 
as B. nitidulum.—L«xo.] [437] 

6. B. porsALE Say, Trans. Amer. Philos. Soc.—This species 
varies considerably. The dorsal line is more or less obvious, and 
sometimes rather deeply impressed. In one specimen is a slight 
appearance of puncturing on the middle of the thoracic base. 
The thorax is more or less engraved with undulated lines, which

Meg. 

7. B. rerracotum Say, Trans. Amer. Philos. Soc.—Allied 
most closely to Peryphus rupestris Illig., than which it is some-

tennz fuscous, piceous at base; palpi dark honey-yellow; mandibles 
at base piceous; thorax bronze black, very obscurely piceous on 
the middle of the anterior margin ; contracted behind ; posterior 
angles obtuse angular ; dorsal line impressed ; anterior transverse 
very obvious, arquated; basal line dilated, suborbicular; basal 
margin with slight inequalities or punctures between the basal 
lines; a slightly elevated line on the lateral margin, forming a 
groove with the slightly elevated edge, more obvious near the 
angle, and becoming obsolete before ; elytra very dark honey-yel- 
low or brownish, much paler at tip; strize somewhat dilated, and 
with dilated, quadrate, profound punctures; striz more slightly 
impressed towards the tip, and the punctures obsolete ; third in- 
terstitial space a little broader than the others, with a puncture 
before the middle and another equidistant behind the middle, 
both nearer the third stria ; wings perfect ; beneath black ; abdo- 
men tinged with piceous; feet pale yellowish. 

Length one-fifth of an inch. 

Resembles tetracolum Say, but the elytral striz are more di- 
lated, the punctures of the third interstitial space are more an- 
terior, and the posterior pale spot of the elytra is quite terminal. 
Belongs to the genus Peryphus Meg.

I obtained this species during the journey of Major Long’s 
party to the Rocky Mountains. It is very distinct from the i- 
equale Say, which it somewhat resembles by many characters. 
That of the rectilinear fourth stria of the elytra is an obvious 
one.

thorax widest before the middle, gradually contracting by an al- 
most rectilinear, but hardly perceptible concave line, to the basal 
angle, which is rectangular; dorsal line but slightly impressed, 
obsolete before ; basal lines hardly distinct from the depressed 
basal margin, which is minutely wrinkled ; elytra with impressed, 
punctured strize, obsolete at tip; seventh stria wanting; third in- 
terstitial line with two small orbicular punctures, one before the 
middle and the other a little behind the middle; a very large 
common blackish spot on the middle, within which the suture is 
reddish-brown ; suture behind the spot blackish ; a small, obso- 
lete blackish spot at the base each side of the scutel; feet pale 
yellowish. 

Length one-tenth of an inch.

the posterior edge ; elytra polished, with a profoundly impressed, 
somewhat dilated, simple, sutural strixe; the second stria obso- 
lete ; an interrupted stria on the lateral margin ; a dilated inden-

a dilated vitta from the humerus, near its tip, curves a little to- 
wards the suture; and is in that part a little more dilated ; venter 
black piceous; feet honey-yellow. 

Length over four-fiftieths of an inch. 

Resembles the preceding, but is destitute of the three punctures 
at the base of the thorax, and with that species belongs probably

palpi and antennz yellowish; thorax honey-yellow ; posterior 
margin black, which is more dilated on the middle half; elytra 
with three series of distant slight punctures; on the lateral sub- 
margin a yellow vitta, which passes a short distance on the hu- 
meral base, and posteriorly diverges a little from the margin, 
attenuates, and does not reach the tip; margin and epipleura 
dull rufous, not reaching the tip; beneath piceous-black ; pectus

4. S. BLANDUS Gray.—The reddish color of this handsome 
insect is of a tint approaching sanguineous. 

Gravenhorst had probably old specimens, of which the color 
had faded. He describes the feet as “ rufo testacei,” but in my 
specimens the tibia and tarsi are piceous. He says “ coleoptera 
depilia,” but my specimens certainly have prostrate hairs on the 
elytra as well as on the seutel. If this is not in reality Graven- 
horst’s species, it differs in the exceptions I have stated, and can 
be called /xtulus. Fam. Ist.

9. S. CYANIPENNIS Fabr.—The allied species of the United 
States was considered by Gravenhorst as a variety only of the 
European species. I have not at present in my collection the 
true cyanipennis of Europe to compare, but as Gravenhorst mentions 
a difference in the size of the head, it may yet prove to be a dis- 
tinct species, and, if so, the name proposed by Knoch, S. ceyanop- 
terus, will be an appropriate one. Fam Ist. 

[Also a Philonthus.—LEc. } 

10. S. vipvatus F.—This name has the priority over that of 
maculosus Gray. Belongs to Family 4. It is singular that Gra- 
venhorst, in his revised work the ‘‘ Monographia,” quotes the 
proper name of this insect and yet retains the synonym of macu- 
dosus as the true name, although it was given by himself a year 
after the Fabrician name. 


11. 8. vionacrus Grav.—This species is subject to vary con- 
siderably ; the “linea media longitudinali levi” of the head is 
very commonly obliterated by punctures, and there exists a variety, 
of which the elytra are tinged with greenish, or are dusky brassy.

them has four only as stated in the description. Belongs to Fam. 
Ist. 


13. S. ATER Grav.—-In my cabinet I find that I formerly 
placed this species under the genus Astrapxus Gray., from the 
circumstance that the terminal joints of the palpi are more dilated 
than in any other species of Staphylinus, that I am acquainted 
with. The terminal joint of the maxillary palpi, is not longer 
than the penultimate one, and the diameter is nearly, if not quite 
as great; the terminal joint of the labial palpi is very obviously, 
dilated, oval, and its transverse diameter is nearly double that of 
the last joint of the maxillaries. Still, however, as neither of 
these joints can be called securiform, agreeably to the essential 
characters of Astrapzus, we must agree with Gravenhorst, and 
return the species to his third family of Staphylinus, from which 
it certainly differs in the characters above stated.

larger puncture each side at base; and a slight longitudinal in- 
dentation on the basal margin ; thorax as wide as the head ante-

is more than probable that the insignitus is also a distinct

This occurred extremely numerous, in October, under the sur- 
face of the sand in flat places on the sea beach, over which the 
high tides flow. When the water subsides, their labors become 
visible. They proceed forwards a little beneath the surface in a 
very irregular line, casting up the sand so as to resemble a 
miniature mole tunnel. 

On the wet or partially dry plain, their tunnels, though very 
small, are yet very striking to the eye, in consequence of their 
great abundance, and being drier and whiter than the general 
surface. They appear to be in search of the various minute 
crustaceous animals, that take refuge in the sand on the recession 
of the waters.

M. natipes Gray. Monog. Coleopt. Micr., p. 198. 

In the present state of the science, the datipes can no longer 
remain in the genus Oxytelus, as a species of which Gravenhorst 
described it. That author was, however, perfectly sensible of 
its distinguishing characters, and had he written twenty years 
later, I should not now have to construct this new genus. The 
following are his remarks adjoined to his copious description, to 
which I must refer the reader : 

“ Cum hoc insectum palpis instructum sit filiformibus, antennis 
extrorsum crassioribus, thorace immarginato basi truncato, Tachi- 
nis adnumerandum foret, si solos characteres artificiales (Coleopt. 
Micropt., p. 134) datos respiceremus. Habitu autem toto, et ex- 
ceptis ultimis palporum articulis, partibus etiam singulis cum 
Oxytelis hujus familiz plane congruit. Certo systematis natu- 
ralis nullam haberemus rationem, cum hoc micropteron Tachinis 
adjungeremus. Oxytelis autem, sicut huc usque determinati 
erant, ob characteres per systema artificiale constitutos, haud 
adsociari potest. KHodem ergo jure, quo Astrapaei genus olim a 
Staphylino disjungebatur, quibus attamen simillimum est, hoc 
etiam insectum genus novum, ab Oxytelis separatum, conderet, 
nisi regula systematis naturalis, i. e. character totus externus 
seu habitus totus, dissuaderet.”’ [463 |

Herbst says the side of the thorax is rectilinear, not arcuated. 
This would agree better with /urida F.; my specimens of ob-

[This and the two following belong to Chrysobothris—Lxc. ] 


6. B. HYBERNATA F.—From the specimen in my collection, 
T am led to believe that the hybernata ¥., is but a variety of the 
frontalis Olivier, and that both have serrate elytra; but I have 
not at present the means of referring to Olivier’s work. My 
specimen is reddish purple; thorax immaculate ; elytra serrate, 
with but five green spots; and the anterior thighs are armed 
with a prominent tooth.

There is some confusion amongst the species of the small group 
to which this belongs, in consequence of the short descriptions 
of Fabricius. Herbst’s description of this species cannot well 
be mistaken. I have found it in Pennsylvania, [159] Florida 
and Arkansa. It is the ornata of Dejean’s Catalogue; and

Germar, in a letter, considers it a new species under the name of 
olydonia. 

[This and the two succeeding species belong to Acmzodera.— 
LEc.] 


10. B. ornata.—About the size of the preceding, though 
perhaps a little more robust, of a much darker color; and may 
also be distinguished from it by the thorax haying the dorsal line 
deeply indented, more especially on the posterior margin, and 
being obtusely angulated behind the middle of the lateral edge. 
Dejean supposed it a new species, and gave it, in MSS., the name 
of multiguttata, but I think there is no doubt that it is the 
Fabrician species. i) 

11. B. tusutus F.—This species is described as having but 
five yellow punctures on the elytra, placed 2, 2, 1, the latter 
being the largest. But it varies considerably in this respect, 
sometimes having eight or nine spots, and again other specimens 
occur with not more than are indicated by Fabricius, if we con- 
sider the posterior larger one as being composed of two confluent 
ones. The rest of the description agrees precisely, and even the 
noted size corresponds with our insect; as Fabricius says, 
“statura omnino C. volvuli, at duplo minor.” It may indeed be 
at once distinguished from pulchella by its much inferior size, 
very different color, and the greater regularity of its elytral spots ; 
but the lateral edge of the thorax has a similar curvature. It is 
the smallest of our species of the group distinguished by the want 
of scutel, &c.. and approaches the ornata by its coloring and the 
somewhat similar arrangement of the elytral spots, but differs in 
the regular curvature of its lateral thoracic edge. It is the 
volvulus of Dejean’s Catalogue. Germar believed it new and 
gave it the name of xanthocyma ; it is the culta of Weber; and 
Dr. Harris has described it under the name of geranii. 


12. B. acornis.—Brassy black ; antenne short; scutel green ; 
beneath cupreous.

Body with dense, rather large, confluent punctures: head a

cave curvature: labrum hardly prominent, not visible when 
viewed from above : antennz very short, not reaching the vertex, 
the three basal joints together about as long as all the others 
combined ; thorax in breadth at least [160 ] twice the length, 
with transverse confluent punctures: scutel bright green: elytra 
with transversely confluent punctures; serrate from near the 
humerus; surface obsoletely undulated: beneath cupreous: an- 
terior thighs with a prominent acute spine. 

Length seven-twentieths of an inch. 

A small and distinct species.

13. B. impepira.*—Elytra bluish-green, grooved and pune- 
tured. 

Inhabits Pennsylvania. 

Head confluently punctured, green with a cupreous reflection: 
antenne steel-blue, at base green: labrum green, ciliate at tip: 
thorax cupreous, with green confluent punctures; on some parts 
of the disk the punctures are sparse: scutel oval, regularly con- 
cave, green ; elytra densely punctured, with five dilated grooves 
and four elevated lines, the latter sparsely punctured; green, 
gradually shaded into a blue vitta along the middle; suture and 
outer margin cupreous; tip somewhat truncated: beneath green 
cupreous. 

Length three-fifths of an inch. 

The specimen was taken near Philadelphia. It is evidently 
related to salisburiensis, as described by Weber, to decora F., and 
splendens F., of China. But Weber’s description states the 
former to have striated elytra, without elevated lines. The 
splendens has only three elevated lines on the elytra, and the 
decora is larger, with the tip of the elytra two-toothed. Neither 
can it be the striata Oliv., as the elytra are not slightly bidentate, 
nor are their two inner elevated lines abbreviated. A variety 
found by my brother, B. Say, in New Jersey, is much tinted 


* Dr. Harris is of opinion that this species, the aurulenta of Linneus 
and Olivier, and the striata of Fabricius are the same; and that the 
decora F. and salisburiensis Weber and Herbst, are identical. The latter 
differ from the aurulenta L., in not having elevated lines on the elytra.

with copper, and is smaller, but the sculpture and form are the 
same. 

I may add, as closely allied to the impedita and to the salis- 
buriensis Web., in point of coloring, a specimen which I found 
in New Jersey many years since, and which I then described 
under the name of ultramarina; but the description was mis- 
laid and never published, and the specimen is now deprived of 
its head and thorax. The following is a description of what re- 
mains of it. [ 160 | 

Scutel orbicular, disk indented : elytra blue on the disk; sub- 
margin and subsuture green, passing into golden towards the 
margin and suture which are brilliant coppery or red golden ; 
basal margin green golden ; surface with seven or eight stria of 
dilated profound punctures; the interstitial lines with each a 
single series of smaller punctures ; elevated lines; tip truncated, 
with a slight projection at the inner angle : beneath green-golden, 
with a slight coppery tinge: tibiae coppery. 

Length of the elytra two-fifths of an inch. 

It is more brilliant than either the tmpedita or salisburiensis. 
From the former it is distinguished by being destitute of elevated 
lines on the elytra, and from both by its regular series of large 
profound punctures. 

[I agree perfectly with the opinions of Dr. Harris expressed 
in the note on the preceding page, except in regard to the B. 
aurulenta mentioned, which is not that of Linneus, but of Oli- 
vier and several later authors. The description of Linneus, 
Syst. Nat. 1, 661, makes no mention of the elytral costa, and 
applies better to A. decora than to A. striata; the name has 
produced so much confusion, that it should not be applied to 
any species, but should rather be altogether dropped; B. uléra- 
marina is an Ancylochira very closely allied to A. decora, but 
of a broader form, with the intervals of the elytra less irregularly 
punctured, especially towards the suture, with the tips rounded 
or truncate and not bidentate. 

Messrs, Laporte and Gory, by unaccountable carelessness, have 
affixed this name to a species of Chrysobothris—LxE¢. ]

very different in form, which is much more like that of a true 
Buprestis ; and the color is also different, though that of the 
head and thorax probably deceived him, being coppery in each, 
though much more obscure in our insect. I have taken a variety 
in this State differing greatly in color, so much so, that it might 
lead to error unless actually compared. 

The color is bright green; thorax on the dise tinged with 
coppery, with a common green triangle extending from the 
humerus to beyond the middle; beneath the green color is less 
brilliant. Another variety has the cupreous color of the thorax 
confined to the lateral margin, the remainder being of the color 
of the elytra. 

I may add to the specific description that the head has an or- 
bicular indentation between the eyes, and a slightly indented 
line on the vertex ; the scutel is altogether destitute of a trans- 
verse elevated line; it is convex, and widely triangular; the 
elytra are minutely serrate at tip. 

This species has characters in common with Buprestis and 
Agrilus, and it may perhaps belong to the latter. 

[Two species of Anthaxia are here confounded together: one 
is A. quercata, the other a variety of A. viridicornis— Luc. ] 


AGRILUS Megerle. 


1. A. RuFIcoLLIS F.—We may add to the Fabrician charac- 
ters that the head is profoundly indented on the vertex ; the in- 
dented line is continued down the front; the elytra are scabrous, 
and at tip, as well as that of the abdomen, serrate. 

Var. a. Thorax obscure green. [ 162] 

Var. b. Thorax color of the elytra. 

The great indentation of the vertex distinguishes this species 
from others of this country. Herbst’s figure only tends to mis- 
lead, if indeed it can be intended for this insect at all. It is too 
robust, the thorax is not represented as indented, and the elytra 
are punctured in striz, with large punctures. 


2. A. GEMINATUS nob.—A numerous species ; the color of the 
head and thorax often resembling those of the preceding species, 
but the acute, arcuated elevated line at the posterior angles, is 


1836.] 


596 TRANSACTIONS OF THE 


similar to that of the linearis F., of Austria, which it very much 
resembles. 

3. A. PoLITUs nob.—Much like arcuatus, but a little more ro- 
bust, and of a brilliant color. Like the other species its elytra 
are denticulated at tip. Having examined numerous specimens, 
I find that it is not of a larger size than geminatus. 

4. A. ARcuATUS nob.—A little larger than geminatus, and re- 
sembling it in the character of the elevated line at the posterior 
thoracic angles, but the antenng are much more slender and 
elongated. 

5. A. GRANULATUS nob.—This species has three hardly visible 
fulyous spots on the elytra; one on the depressed base, one near 
the suture before the middle, and one behind the middle, also 
near the suture. I have a specimen in which these spots are 
not at all visible. 

The elevated line at the posterior angles of the thorax is short, 
but very obvious. 


6. A. BILINEATUS Weber, nob.—In my printed description 
an error occurs. When describing the elytral vitte, instead of 
“extended towards the tip, where it gradually approaches the 
scutel,”’ I should have said suture instead of “ scutel.” 

7. A. LATERALIS nob.—I stated in the description that the 
elytra are entire ; I would add that they are not obviously denti- 
culated at tip. 


8. A. pusILLus nob.—The smallest North American species I 
have yet seen. 

The above species of Agrilus, excepting the first, I described

most entomologists yet refer their kindred species. [163 ] 


9. A. FALLAX.—Elytra with about three spots on each, which 
exhibit a different reflection. 

Tnhabits Indiana. 

Brassy-greenish: head green, sometimes cupreous on the ver- 
tex ; impressed line hardly obvious: thorax with a dorsal and 
lateral indented line ; the former more obvious behind, the latter

oblique and dilated ; more or less tinged with cupreous; an arcu- 
ated, elevated line at the posterior angles ; posterior angles acute : 
elytra with the basal indentation, subsutural spot behind the 
middle, composed of minute prostrate hairs, producing a differ- 
ent reflection from that of the general surface; tip denticulate : 
beneath blackish-brassy. 

Var. a. Dull cupreous; thorax brighter. 

Length more than one-fifth of an inch. 

Distinguished by the elytral spots offering a different reflee- 
tion from the remainder of the surface. In some positions they 
are hardly obvious; but seen from before or behind they are dis- 
tinet, particularly the posterior one. 


10. A. purmius.—Thorax transversely indented before and 
behind the middle ; elevated line of the posterior angle none. 

Inhabits Indiana. 

Body blackish-brassy : head greenish ; longitudinal impressed 
line very distinct: thorax with a transverse indentation before, 
a much larger transverse indentation behind the middle, and a 
more profound lateral one parallel with the lateral margin; pos- 
terior angles destitute of an elevated line, retangular or rather 
more obtuse; elytra, basal indentation ovate-oblong, oblique ; tip 
denticulated, from the suture to the middle concave; suture 
rather prominent. 

Length over one-tenth of an inch. 

Only three of the before mentioned species are destitute of an 
elevated line at the posterior thoracic angles, viz. the rujficollis, 
bilineata and lateralis, to these we may add the cogitans Weber. 
From all these the present is separable by its inferior size, ex- 
cepting the /ateralis, which has no denticulations at the tip of the 
elytra. One of my specimens has the head green before. 


11. A. orrosus.—Line of the thoracic angles short and ob- 
tuse; front but slightly punctured. 

Inhabits Indiana. 

Body greenish, or brassy-blackish, rather slender : head with 
the punctures obsolete, excepting on the vertex, where they are 
not profound [164] or well defined; beneath the middle of the 
front with short whitish hairs: thorax with two slight indenta-

tions placed longitudinally, a more obyious one on the lateral 
margin, and another each side of the basal middle ; elevated line 
of the posterior angles less than one-fourth of the length of the 
lateral edge, but slightly elevated and obtuse: elytra depressed 
from the suture to the middle ; tip denticulated. 

Length nearly one-fifth of an inch. 

Resembles geminatus, but its form is rather more slender, the 
frontal punctures are obsolete, and the elevated line of the thora- 
cie angles is much shorter and less distinct. 

12. A. cocirans Weber.—The thorax is deseribed to be 
serrate ; but on close examination the edge will be found to be 
entire, and the upper surface of the edge, or extreme margin 
only, is serrate. The body is more dilated than in any other of 
our species.

Thorax short, wide, and deeply emarginate before for the re-

rest the tarsi are applied to the outer edge : praesternum promi- 
nent to the mouth, and behind applied evenly to the poststernum

behind ; in the prasternum terminating by a straight line; by 
the dilatation of the tibia, Ke.

rus ; punctures rather large but not deeply impressed, placed in 
series and obsolete behind: tibiz angulated. 

Length under three-twentieths of an inch.

I was deterred from referring this species to Cerophytum Latr.,

corps est ovale.”” Our insect cannot therefore be the Melasis 
picea Beauy., which is referred to Cerophytum.

1. E. optessus nob. (discoideus Fabr.)—The Fabrician 
phrase, when describing the elytra, is, “elytra striata, atra, mar- 
gine baseos lateralique late albo;” but as the whitish portion 
oceupies about two-thirds of the whole surface and might lead to 
error, it would be better to say, elytra whitish, with the sutu- 
ral margin and exterior edge, excepting at base, black. 

I change the Fabrician name, because it is preoccupied by 
Weber for a very different species of this country.* 


* Dr. Harris says that Weber’s species here referred to, is the hamatus 
of Fabricius ; and that Mr. Say does not seem to have known the Elater 
discoideus of Fabricius, which is quite distinct from the above named

56. E. MARMOoRATUS F.—Our largest species of this division 
that I have seen. I have found it as far north as Canada, and 
Mr. Nuttall presented me a specimen from Arkansa. It occurs 
both in Pennsylvania and Indiana, and Dr. Harris sent me a spe- 
cimen which was found in N. Carolina. The thorax may be de- 
seribed as unequal, as it has several indentations ; the pectus has 
deeply impressed tarsal grooves; the clypeus is concave. [181] 

57. E. opercunatus 8., Ann. Lyc. N. Y.*—Belongs to this 
division. Dr. Harris sent me specimens from Massachusetts 
and New Hampshire. 

[Probably the species afterwards described by me as Adelocera 
brevicornis is here intended.—LEc. | 

58. E. Auroratus.—Blackish, sprinkled with golden seales ; 
pectoral tarsal impressions not profound. 

Inhabits New Hampshire. 

Body blackish, punctured, with bright yellow scales: clypeus 
not conspicuously concave before: thorax convex; a longitudi- 
nal, impressed, but not much dilated line, obsolete on the ante- 
rior third; lateral edge regularly arcuated to the origin of the 
posterior angles, which are rather broad, acute, and extending 
outward and backward, with their exterior edge perfectly rectilinear 
to the tip, basal edge sinuous ; elytra destitute of elevated lines at 
base: pectus, tarsal impressions not deeply marked, but distinct, 
concave: tarsi rufous. 

Length eleven-twentieths of an inch. 

Sent to me for examination by Dr. Harris. The lateral edge 
of the thorax is not undulatedly arcuated as in 2. marmoratus F., 
and £. operculatus 8. 

[Belongs with the two following species to Adelocera.—LEc.]

Body blackish piceous: clypeus transversely concave before : 
thorax rather short and wide ; dorsal groove much dilated, the top 
of its lateral elevations being equidistant from the middle of the ex- 
terior edge; exterior edge arcuated, not undulated ; lateral mar- 
gin broadly depressed ; posterior angles rather broad, extending 
outwards and backwards, their exterior edge rectilinear to the 
tip: elytra with elevated, obtuse lines at base, one of which is 
obliquely elongated and is obsolete behind the middle: tarsal 
groove of the pectus none. 

Length three-fifths of an inch. 

For this species I am indebted to Dr. Harris. It is as large as 
marmoratus F., and operculatus 8., to the latter of which it ap- 
proaches in being destitute of the tarsal grooves of the pectus, 
and in the short wide thorax ; but it differs from it in the more 
regular arcuation of the lateral edge of the thorax, the exterior 
edge of the posterior angles [ 182 ] being rectilinear, and in the 
crimped appearance of the base of the elytra, &c. 


60. E. piscorprus Weber.*—Remarkable by the golden hairy 
head and sides of the thorax. This is the pennatus Fabr.; but 
Weber’s name has the priority, and must therefore be adopted. 


61. E. reprurus. Blackish; spines acute; elytra with ap- 
proximated series of punctures. 

Inhabits United States, Pennsylvania, Indiana, and North 
Carolina. Harris. 

Body black-brown, punctured, rather slender: clypeus concave, 
truncate at tip, and emarginate each side at the insertion of the 
antenne : antenne rufous, serrate; second joint not half the length 
of the third: thorax with a dorsal, slightly indented line ; lateral 
edge not arcuated; a little narrowed before, and contracted at 
the spines ; spines excurved, acute: scutel rounded behind: ely- 
tra with approximate series of deep punctures, with an appear- 
ance of striae, the series alternately larger : pectus, tarsal grooves 
obvious. 


~* ‘¢Observationes Entomologice.’? This work, which was presented 
to me by Professor Wiedemann, was published in the same year with the

hardly elevated before ; anterior edge very obtusely arcuated, a 
little concave ; antenne serrate, rufous; second joint small, sub-

scutel concave, rounded behind ; elytra [183] with hardly percep- 
tible, raised lines: punctures profound, densely and irregularly 
set: feet piceous: pectus, tarsal grooves none. 

Length eleven-twentieths of an inch. 

Smaller than £. marmoratus F., and more slender, with a 
more equal thorax ; larger than LZ. /epturus 8., discoideus Weber; 
impressicollis §., and rectangularis §., and the punctures of the 
elytra are not in regular series. It seems to approach nearer to 
E. operculatus S., but the elytra are more obtuse at tip, and have 
much more profound, large, and close set punctures. I have not 
now an entire specimen of the latter species, and therefore can- 
not compare with the anterior part of the body.

The second and third joints of the antenne are rounded, equal.

basal margin of the thorax has a fissure each side. 

Length from three-tenths to seven-tenths of an inch. 

The former size is rare; but the more usual length is about 
half an inch. 

This is the vulgaris and pilosus of Melsheimer’s Catalogue. 
It resembles the brunnipes Ziegler; but the thoracic punctures 
are rather larger, and less crowded, the thoracic spines are longer 
and more acute, and the second joint of the antenngs is a little 
longer in proportion to the third.* [184]

The thoracic fissures readily distinguish this species. I formerly 
marked it in my cabinet interr ogatively as the brevicollis Herbst; but

Descriptions of new North American COLEOPTEROUS INSECTS, and 
Observations on some already described. 


Communicated Feb. 1835. 


In this number we present to our readers a part of the hither- 
to unpublished entomological papers of the late Thomas Say. 
This distinguished and lamented American naturalist was en- 
gaged in preparing them for publication in the Boston Journal 
of Natural History, when his labors were prematurely arrested 
by the disease which proved fatal to him, on the tenth of Octo- 
ber, 1834. In justice to his memory, it becomes our duty, with- 
out delay, to publish these posthumous papers, and thereby to 
secure to his names, as far as possible, the right of priority. 

These papers consist of descriptions of New American Coleop- 
terous and Hymenopterous insects, and remarks upon some al- 
ready described. The Hymenoptera will appear in our next 
number.—Pub. Committee.

is deficient in the specimen, I cannot determine positively ; and, 
furthermore, the circumstance of the second and fourth elytral 
costee not being obviously elevated, leads to a doubt.

2. 8.? BRUNNEUS.—Blackish-brown ; antenne sericeous-brown ; 
thorax with two indentations on the disk. 

Inhabits Indiana. 

Body blackish-brown, punctured, oblong; head with small 
punctures, rather prominent between the antenne, above which 
it is somewhat indented ; antenne as long as the thorax or rather 
longer, brown sericeous; thorax with small punctures, anterior 
and posterior angles dentiform; disk with a small orbicular in- 
dentation each side behind the middle, and an irregular one on 
the basal middle ; posterior margin each side of the middle a lit- 
tle concave ; scutel orbicular; elytra with numerous somewhat 
large punctures ; not in striz, with four slightly elevated lines or 
nervures, the inner one abbreviated before the tip, the others 
confluent near the tips. 

Length from two-fifths to three-fifths of an inch. 

This insect approaches, in character, nearer to Sandalus than 
to any other genus. In that genus the mandibles are remarka- 
bly faleate, and the tooth is on the inner side, towards the base ; 
they are also covered to the middle by a membrane or coriaceous 
process ; the tibiw are quadrilateral and denticulate, and the 
tarsi beneath are clothed with very dense hairs. In our insect 
the conformation of the antennz is the same as in the female of 
Sandalus, excepting that they are much more elongated ; the 
mandibles are less prominent, and have the tooth on the superior 
side near the tip, which is therefore emarginate, or rather bifid, 
and are destitute of any membranous covering at base ; the tibia 
are not quadrangular, the tarsi are simple beneath, and the men- 
tum is somewhat transversely oval, with a robust dentiform pro- 
cess before. It can be separated under the name of Zenoa. 

I have found it under the bark of decaying trees. 

Vid. Gen. Analestes Leach, or Cebrio. Probably C.. bicolor, 
but it does not appear to agree with Fabricius’s description.

T.? TERMINATUS.—Black ; terminal joint of the antenns as 
long as the head and thorax. 

Inhabits United States. 

Body black, densely punctured and with numerous cinereous 
hairs: eyes reniform, emargination very profound: antenne, 
radical joint suboval; second joint globular ; third, fourth, fifth 
and sixth, very short, transverse, approximated ; seventh, eighth 
and ninth, rather larger, serrate ; terminal one greatly elongated, 
longer than the head and thorax, and about three times as long 
as all the preceding joints conjunctly, much compressed, linear, 
with dense minute black hairs, tip and base rounded: labrum 
rounded at tip: mandibles bifid at tip : thorax cylindrical, hardly 
narrowed at base, margin rufous: tarsi distinctly five articulate ; 
first joint longer than the second; penultimate one bilobate : 
nails dentated : abdomen sanguineous ; terminal segment black. 

Length rather more than one-fourth of an inch. 

T obtained two specimens of this curious insect, at the [ 161 ] 
cantonment of Major Long’s party near Council Bluff on the 
Missouri river. It occurs also in Indiana and Pennsylvania. 

By the form of the tarsi, palpi and thorax, it approaches the 
present genus; but the extraordinary conformation of the an- 
tenn seems to require a separation from the other species, at 
least in a distinct subgenus.

maxillary palpi with the last joint rather small. 

Inhabits Indiana. 

Body elongated, blackish-piceous, with pale hairs, punctured : 
head, punctures somewhat confluent, so as to present a rather 
granulated appearance: antennz honey-yellow, terminal joint 
hardly larger than the preceding one: labrum piceous, obtusely 
emarginate: mandibles piceous at base: maxillary palpi with 
the terminal joint small: thorax with an obtuse tubercle each 
side of the middle, on which is an indentation ; an impressed, 
transverse line before the middle and a contraction behind the 
middle ; an indentation on the basal margin ; punctures not pro- 
found, transversely confluent: elytra with deeply punctured 
striz : coxee and tarsi honey-yellow. 

Length two-fifths of an inch. 

This species agrees with all the characters of the present 
genus, as laid down by Kirby, with the exception of the magni- 
tude of the terminal joint of the maxillary palpi, which is much 
smaller than that of the type of the genus. It is rare.

Body oval, deep black: antennze piceous: head and thorax 
with small, regular, subequidistant punctures : elytra punctured, 
very obtusely rounded at tip, almost truncate; each elytron with 
two yellowish spots, slightly tinged with rufous; the basal one 
areuated so as to enclose the humerus; posterior one behind the 
middle transversely oval, not sinuated; terminal lateral margin 
obscurely piceous : beneath piceous-blackish. 

Length slightly more than one-fifth of an inch. 

Very similar to the Nitidula fasciata Oliv., but it may be dis- 
tinguished by its uniformly small spots. The Lngis confluenta

reaching the middle of the humerus, and an intermediate one 
hardly more than one-fourth of the length of the elytra; tip

with short hairs, another narrower impressed line nearer the eye: 
antenne, first joint of the club with an acute ciliated process: 
second joint triangular, small, the anterior angle prominent, 
acute; terminal joint subovate, rounded at tip: palpi rufous,

HYDROPHILUS Fabr. 


1. H. Mercus.—Black, highly polished ; sternum not reach- 
ing the middle of the venter. 

Inhabits Mexico. 

Body highly polished, black, oblong-oval; head with an ab- 
breviated line of impressed, confluent punctures on the inner or- 
bit ; a much arcuated line of punctures from the anterior can- 
thus terminates between the eyes; thorax with a much abbrevi- 
ated, oblique line of punctures each side; elytra with three se- 
ries of distant, obsolete punctures; exterior series remote from 
the others ; sternum not canaliculate, not extending to the mid- 
dle of the venter; feet more or less piceous. 

Length nearly seven-twentieths of an inch. 

In comparison with HH. natator nob., which it closely resem- 
bles, the surface is more highly polished, the sternum much 
shorter and without any appearance of a groove between the an- 
terior pairs of feet. 

2. H. EXSTRIATUS.—Subsutural stria none, black ; thoracic 
edge and beneath piceous. 

Inhabits Louisiana. 

Body short-oval or rounded, convex, glabrous, black ; [172]

palpi and base of the antenne pale yellow; three last joints of 
the latter fuscous ; thorax piceous on the lateral and posterior 
margins; scutel small, with but few punctures ; elytra destitute 
of striz, and without any appearance of one on the sutural mar-

tarsi yellow, brighter beneath. 

Length less than three-twentieths of an inch. 

This species was sent to me by Mr. Barabino. It is smaller 
than the orbicularis F., which it resembles much in the punctur- 
ing and form; but that species has the subsutural stria extend- 
ing from before the middle to the tip of the elytra.

Body black, polished, punctured; head with two transverse, 
elevated lines ; posterior line between the eyes, and slightly emar- 
ginate in its middle; anterior line a little more elevated in the 
middle, equidistant from thetip of the clypeus and posterior line ; 
tip slightly contracted ; antenne ferruginous ; thorax on the mid-

nutely punctured ; head and thorax with a hardly perceptible 
tinge of green. 

Length over three-tenths of an inch. 

The specimen is probably a female. It is smaller than the 
O. taurus Linn., the female of which it resembles in the form and 
disposition of the lines of the clypeus. It is much larger than 
O. latebrosus Fabr., from the female of which it differs consider- 
ably in the form of the elevated lines of the head, but agrees in 
having a thoracic prominence ; this prominence, however, is more 
obvious, and widely emarginate. 

2. QO. viripicatTus.—Green ;  elypeus bidentate; elytra 
smooth. 

Inhabits United States. 

Scarabus smaragdulus Fab. Melsh. Catal. 

Body robust, green; head bidentate at tip; antenne black- 
ish ; thorax on the lateral edge a little angulated before the mid- 
dle ; elytra smooth, impunctured, or with [174] three or four 
hardly perceptible impressed lines; beneath dark green. 

Length nearly one-fifth of an inch. 

Certainly not smaragdulus of Fab., but it is related, in point of 
size and form to Copris subzneus Pal. de Beauy., of which, how- 
ever, he remarks, ‘‘Clypeo integro, transverse bicarinato,”’ and 
“ses élytres sont d’un noire terne, les stries peu marquées, et une 
rangée de points élevés entre chacune,” which prove it to be very 
different from our species.

3. O. ovatus Fabr. 

Our specimens are subject, like the European, to vary consid- 
erably in magnitude and some other characters; but I have not 
observed any trait which can justify the separation of it from the 
Fabrician type.

COPRIS Fabr. 


1. C. coLonica.—Thorax somewhat retuse ; head with a short 
elevation between the eyes. 

Inhabits Mexico. 

Body black ; head a little rugose, witha slightly elevated, com- 
pressed, rounded horn, broader than high, situated between the 
eyes and not surpassing the line of [175] their anterior canthi ; 
tip of the clypeus rather acutely rounded ; thorax somewhat ab- 
breviated dorsal line behind the middle, and a deeply indented, 
oval impression on the middle of the lateral margin; punctures 
small, very numerous ; elytra with indented, punctured stria ; 
interstitial spaces convex. 

Length nine-tenths of an inch. 

Resembles C. carolina Fab., but is not so robust, and the the- 
rax is much less elevated behind. The horn of the head, also, 
in Carolina is equidistant between the eyes and the tip of the 
clypeus. It is also like Micanor ? as figured by Drury i. pl. 35, 
fis. 1: 

2. C. INCERTA.—Thorax simple, with an impressed line; head 
horned ; elytra striate. 

Inhabits Mexico. 

Body black, somewhat polished ; head with dense, shallow 
punctures; a short, conic, vertical horn on the middle; tip of 
the clypeus acutely and rather deeply emarginate ; thorax punc- 
tured except on the posterior disk ; a deeply impressed line from 
a little before the middle to the base, and an impressed oval spot 
each side ; anterior margin rather abrupt; elytra with deeply 
impressed, crenate strie; interstitial spaces convex, impunc- 
tured. 

Length nearly seven-tenths of an inch. 

I should be inclined to consider this as as the female of the 
procidua nob., but in that species the larger horn is very near 
the anterior termination of the head, and the posterior horn is 
much shorter and remarkably inclined ; whilst in the present in- 
sect no tubercle exists to mark the locality of the larger horn, and 


1835.] 


650 BOSTON JOURNAL 


the horn that it possesses is larger than the posterior horn of 
that insect, with which it corresponds in locality but not in di- 


rection. [176] 


3. C. QUADRIDENS.—Thorax angulated, four-toothed; head 
horned. 

Inhabits Mexico. 

Body blackish-violaceous ; head densely punctured, and with 
an elongated, recurved, trigonate horn, which is as long as the 
thorax, punctured and acute; thorax rugose, angulated ; poste- 
rior angles compressed, elevated, subacute; on a line between 
them are two remote, short, vertical, conic denticulations ; ante- 
rior margin near the middle with two short, vertical, conic den- 
ticulations separated by a raised line; elytra with obsolete striz. 

Length seven-tenths of an inch. 

A fine species, not so brilliantly colored as the carnifex Fabr., 
or even as the triangulars nob., from both of which it is emi- 
nently distinguished by the thoracic denticulations. 


4. C. procipua.—Thorax three-horned ; head two-horned. 

Tnhabits Mexico. 

Body black ; head punctured, two-horned ; anterior horn ver- 
tical or hardly recurved, not as long as the head; posterior horn 
very short, inclined; thorax punctured, with three horns, the 
middle one very obtuse and emarginate, lateral ones acute, in a 
transverse line on the anterior submargin; anterior margins de- 
clivous; anterior angles rounded; an impressed, abbreviated, 
dorsal line and a lateral indented spot ; posterior disk impune- 
tured ; elytra with impressed, punctured striz ; interstitial spaces 
convex, impunctured. 

Var. a. Highly polished. 

Length more than three-fifths of an inch. 

The armature of the thorax is very similar to that of C. Zuna- 
ris Linn., but it is less robust, and is widely distinguished [177] 
from that species, by having two horns on the head. The variety 
resembles C. Ammon Fabr., anaglyptica nob., in the thoracic 
sculpture.

punctured, excepting on the disk, anterior margin and middle of 
the lateral margin; margin, at the anterior angles, obsoletely dull 
honey-yellow: scutel impunctured: elytra with impressed, very 
regular crenate strize, exterior and terminal margins rather pale 
honey-yellow ; this color dilates towards the tip, and is deeply 
undulated on the inner edge: feet honey-yellow. 

Length less than one-fourth of an inch. 

About the size of A. ater Fabr. 

2. A. sERVAL.—Black ; elytra dull whitish, with black spots. 

Inhabits Indiana. 

Body piceous black, punctured ; head widely emarginated before, 
and with a dull rufous margin; thorax with a dull rufous lateral 
margin: elytra yellowish white, with seven or eight subquadrate 
black spots, and a lateral, abbreviated, black, double, confluent 
vitta: with slender punctured striz; interstitial lines flat, im- 
punctured. 

Length over three-twentieths of an inch. 

Very closely allied to the inquinatus Fabr., and resembles also 
A. contaminatus Fabr., but the clypeus is much more deeply 
emarginated, and is acutely angulated [178] at each end of the 
emargination. ‘This latter species is hairy.

arcuated, exterior edge entire: clypeus not trilobate at tip, entire: 
antennz yellowish at tip: thorax convex, laterally a little dilated 
towards the base; an indentation on the middle of the lateral 
submargin ; elytra with somewhat impressed and punctured [179] 
strie, which are obsolete on the humerus; interstitial lines 
depressed, with minute punctures furnishing hairs. 

Length over one-fifth of an inch. 

A rare insect; I have found but one specimen, which is 
probably a female. It is even smaller than the O. filicornis nob., 
and in form more like the Lazarus Oliy. than the cephus Oliy.

occurs, of which the elytral punctures are much less dilated, and 
the thorax is less deeply sculptured. I have found the species in 
Pennsylvania; Nuttall obtained it in Arkansaw, and Mr. Barabino 
sent me am individual taken near New Orleans. 

A label, attached to a specimen in my cabinet, states that it

edge. They both exhibit a remarkable difference, in their smooth 
surface, from the greater number of the species of this genus.

Body pale, varied with blackish: head punctured, cupreous : 
thorax with minute, distant punctures ; edge blackish-cupreous ; 
disk blackish; this color reaches the middle of the anterior mar- 
gin, is sinuate on the sides and profoundly so behind ; a blackish

double series of impressed punctures similar to the others, but 
approximate, and a single subsutural series; edge all around 
blackish, a humeral spot and middle of the exterior margin 
blackish.

In some respects resembles A. unifasciatus nob., but it is 
larger, with a shorter head, and is very different by other 
characters.

This insect and the preceding may be only varieties ; never- 
theless, having three specimens that are similar to each other, I

posterior margin with an impressed line: scutel triangular: ely- 
tra with impressed, punctured, and crenate striz ; interstitial 
spaces convex, impunctured ; lateral edge acute: anterior tibiz 
with a strong tooth. 

Length half an inch. 

In comparison with 7. reflexus nob., the thorax is larger, more 
arcuated on the lateral edge, and more narrowed behind; the 
anterior tip of the clypeus is not so prominently reflected, and 
the contraction towards the junction of the thorax and abdomen 
is more obtuse. 


2. T. rnurinasus,—Suboval, black; head before, antenne 
and feet ferruginous. 

Inhabits Louisiana. 

Body oval, a little oblong ; densely punctured: head on the 
anterior part obscure rufous ; antenne obscure, [188] ferrugin- 
ous; joints transverse, subtriangular or conic: palpi and mentum 
ferruginous: thorax regularly punctured; basal edge undulated ; 
basal angles rectangular: scutel densely punctured : elytra with 
_regular series of punctures ; interstitial spaces slightly convex, 
particularly the lateral ones, and with three or four irregular 
series of small punctures: beneath ferruginous, punctured. 

Length over one-fifth of an inch. 

Sent to me by Mr. Barabino from New Orleans.

CQDEMERA Oliv. 


(EZ. APICALIS.—Pale reddish-brown; elytra black at tip and 
with four elevated lines. 

Inhabits United States. 

Body rufo-testaceous, densely punctured: eyes obvious emar- 
ginate: mandibles black at tip: thorax dilated each side before 
the middle, narrowed behind: elytra with four narrow, slightly 
elevated lines, on each side of which is a series of more obvious 
punctures ; third line obsolete before the middle; tip black ; 
postpectus, abdomen and feet black, a little sericeous: wings 
blackish. 

Length about half an inch. 

I have found it in Pennsylvania and other parts of the Union, 
and Mr. Barabino sent me an individual from Louisiana. 

{This is the common Nacerdes melanura, imported from

LAGRIA Fabr. 


To this genus, as it is at present constituted, it seems probable 
that the following species belong, rather than to Anthicus, under 
which I published an account of them, stating, at the same time, 
that they differ from the other species of the genus that had 
fallen under my observation, viz :— 

Lagria lugubris, L. collaris, L. terminalis, L. labiata, and L. 
impressa nob., but the orbicular thorax, the nails being armed 
with a tooth or abrupt angle beneath, &c., seem to justify, if not 
the formation of a new genus, pease a Apes of the present, 
under the name of Corphyra. 

[As will be seen ante, 311, these species all belong to Pedilus.

RHIPIPHORUS Fabr. 
R. trMBaAtus Fabr.—Sanguineous; thoracic disk and margin 
of the elytra black. 
Inhabits the United States.

nuated behind, and with a more or less dilated, black spot on 
the middle: elytra with a whitish disk, more or less broadly mar- 
gined with black: thighs at tip, tibie except at base, and tarsi, 
except the base of the first joint, black. 

Length to tip of elytra a quarter of an inch. 

Var. a. Vertex black. 

Var. 8. Elytra black, immaculate. 

Var. y. Beneath varied with black. 

Fabricius was unacquainted with the native country of his 
limbatus, but as his description agrees very well with [190] our 
insect, and was made out from a specimen belonging to the same 
collection in which he described his dimidiatus, I have no doubt 
that it was intended to indicate this species. Dr. Melsheimer 
was of the same opinion, and has recorded the name in his cata- 
logue. I introduce the description for the purpose of preserving 
the Fabrician name for a species not commonly known. 


MORDELLA Latr. 


1. M. nitraris.—Blackish, silvery-sericeous ; elytra with a di- 
lated, irregular, dull yellowish band margined with whitish. 

Inhabits Indiana. 

Body black, somewhat purplish-iridescent, sericeous: head 
dull yellowish-sericeous : thorax varied with gray hairs: scutel 
silvery: elytra with a much dilated, dull golden sericeous, 
oblique band, occupying about one-third, spread widely towards 
the scutel, and margi ned before and behind with a whitish line, 
the anterior line much angulated and the posterior one reclivate ; 
tip rounded: beneath with purple and green reflections, and sil- 
very-Sericeous. 

Length about two-fifths of an inch. 

This has some resemblance to MV. bidentata nob., but it is 
widely distinct by the elytral band and the much more dilated 
terminal joint of the maxillary palpi. It is common about the 
flowers of the Hydrangia cordata Ph. Its movements are rapid. 

2. M. ocunaTa.—Black ; elytra bifasciate, anterior bands with 
two dots. 

Inhabits Pennsylvania and Indiana. 

M, fasciata Melsh. Catal. [191 ] 
18385. ] 


662 BOSTON JOURNAL 


Body black, whitish sericeous : antennz dull rufous, dusky to- 
wards the tip: thorax with two slightly indented dots a little be- 
hind the middle: elytra with a yellow-cinereous band a little be- 
hind the middle, interrupted at the suture and contracted on 
each side, and a mnch larger basal band extending posteriorly 
on each elytra in a point, nearly to the middle, and having a 
subbasal obvious, definite, black dot each side of the suture: 
tibize and tarsi dull rufous. 

Length over three-tenths of an inch. 

The two black dots on the basal band of the elytra are very 
obvious, and serve to distinguish it from JL. fasciata Fabr., which 
it certainly resembles, and to which it has been referred. 


3. M. servAu.—Blackish, spotted with yellowish. 

Inhabits Indiana. 

Body brownish-black: antenne and palpi pale, dull rufous: 
thorax with numerous spots of short, yellowish hairs : elytra with 
numerous subequal spots of short, yellowish hairs, a dentated 
band behind the middle, and narrow terminal margin: beneath 
sericeous: venter each side with obsolete oblique, brown lines: 
tarsi, color of the antennee. 

Length three-twentieths of an inch. 

A very pretty species. 


APATE Fabr. 


A. BICAUDATA nob.—A variety of this species occurred in 
Mexico. It is large, the feet are nearly black, and the punctures 
of the elytra are somewhat larger than in those of this country. 


PARANDRA Latr. [192] 


P. potiraA.—Ferruginous, head and thorax impunctured. 

Inhabits Indiana. 

Body ferruginous, polished : head blackish-ferruginous, almost 
impunctured, excepting behind the eyes, where the punctures 
are numerous ; a longitudinal, slightly indented line before : an- 
tenn ferruginous at tip: mandibles with a large, prominent, 
rounded tooth near the base; then a profound, rounded sinus, 
then a subterminal tooth: palpi ferruginous: thorax blackish-fer- 
ruginous, impunctured, gradually a little narrowed behind ; an ob- 


[Vol. T. 


OF NATURAL HISTORY. 663 


solete indentation in the middle of the lateral margin; lateral 
margin decurved, the edging line hardly prominent, so that, 
when viewed from above, it is not visible; posterior angles 
almost rounded: posterior edging line hardly visible: scutel 
small: elytra minutely punctured ; pectus and postpectus dark 
ferruginous. 

Length about seven-tenths of an inch. 

This species, by its size and color, may be readily mistaken 
for the P. brunneus of authors, but it differs in many characters. 
It has a more slender thorax, whick is not wider than the head. 
The teeth of the mandibles are but two, the basal one being very 
large and remote from the other, so that when the mandibles are 
closed, an oval interval appears, as in the ferruginea Sturm., 
which species, however, has the posterior angles of the thorax 
very obtusely rounded. The P. brunnea has three subequal, 
subequidistant teeth in the mandibles; the head and thorax ob- 
viously punctured, the latter broader than the head, &e. 

The species is rare. [193] 


PRIONUS. 

P. DASYSTOMUS nob.—Occurred near Natchez, on the Missis- 

sippl. 
MONEILEMA Say. 

M. INEQUALIS.—Cinereous ; rough, with elevated points and 
tubercles. 

Inhabits Mexico. 

Body pale, brownish-cinereous : eyes small, distant from the 
antennz : antennz nearer to each other than to the eyes; first 
joint robust, longer than the second and third together ; half the 
length of the body: thorax cylindric-oval, covered with small, 
unequal, irregular elevations: elytra with many elevated tuber- 
cles, of which some form a regular arcuated series from near the 
humerus to the tip, and parallel with the suture beyond the mid- 
dle ; tip entire, as long as the abdomen. 

Length seven-twentieths of an inch. 

Inasmuch as this species is apterous and has a similarity of 
habit, I place it in the present genus, although the approxima- 
tion of the antenne is an obvious distinction.

CLYTUS Fabr. 


1. C. cuarus.—Thorax yellow, with three black dots; elytra 
black ; base, band behind the middle, and tip yellow. 

Inhabits Indiana. | 

Body covered with short, dense, prostrate hair: head black; a 
band on the vertex curving under the head, an abbreviated line 
above the antenne, and front yellow: thorax yellow, with three 
dorsal, transverse, abbreviated, [194] parallel, blackish bands : 
elytra black; basal third a narrow, undulated band behind the 
middle, and tip in which is a small black spot, yellow ; a black 
dot on the humerus: beneath yellow sutures and feet black. 

Length nine-tenths of an inch. 

Somewhat like C. decorus Oliv., and speciosus nob., but the 
bands of the elytra and other characters are essentially different. 
I first observed it near the end of August. It is a remarkably 
fine insect. 

[ Belongs to Arhopalus as enlarged by me. ] 

2. C. CAPREA nob.—Occurred at New Orleans. 


STENOPTERUS Illig. (NECYDALIS Fabr.) 

S. SANGUINICOLLIS.—Blackish, thorax sanguineous. 

Inhabits Indiana. 

Body black, with cinereous hairs, punctured : thorax sanguine- 
ous, inequal, with three more obvious elevations: elytra with a 
longitudinal, slightly elevated line; disk obscurely tinged with 
brownish: feet yellow; club of the thighs and tip of the tibiz 
black. 

Length seven-twentieths of an inch. 

It is more slender than S. preeustus Fabr.; but the thoracic 
and elytral elevations are somewhat similar. 


MOLORCHUS Fabr. 
M. Metirus.—Black ; abdomen, feet and basal joint of the 
antenne honey-yellow. 
Inhabits Indiana. 
Body black: head indented between the antennz: antennze 
about as long as the body, basal joint rufous ; thorax subeylindric, 
contracted before the middle, and with an indented longitudinal

and obsolete spot on the basal middle: postpectus sericeous : feet 
honey-yellow ; tip of the posterior thighs, their tibise and tarsi 
dusky : abdomen honey-yellow. 

Length % nearly three-fifths of an inch; ? over four-fifths. 

In the form of the thorax it is more like M. bimaculatus nob., 
than marginalis, but it is greatly superior in magnitude to either, 
and yery distinct as a species. 


ACANTHOCINUS Meg. 


A. QUADRIGIBBUS.—Antennx annulate; thorax four tuber- 
cled ; elytra with a cinereous spot on each. 

Inhabits Louisiana. 

Body dark brownish, when closely examined, varied with fer- 
ruginous and cinereous, short, prostrate hair: antennz hardly 
longer than the body, blackish ; the joints, excepting the basal 
ones, reddish cinereous at their bases ; basal joint clavate : head 
before remotely punctured; behind the eyes, small, numerous 
punctures : labrum dull honey-yellow: thorax with distant punc- 
tures; four tubercles nearly in a transverse line, and a longi- 
tudinal, elevated line: elytra quadrigibbous at base; inner 
gibbosity extended into a longitudinal elevated line, gradually 
declining and terminating before the tip ; numerous, distant, pro- 
found, punctures; a dilated, undulated, cinereous spot, before 
the middle ; a sutural series of alternate, quadrate, small brown 
and cinereous spots, nearly opposite; tip emarginate: thighs 
clavate. 

Length less than three-fifths of an inch. 

For an opportunity to described this species, I am indebted to 
Mr. Joseph Barabino, who obtained it near New Orleans. 

[Belongs to Acanthoderes.—LkEc. ] [196] 


TETRAOPES Schoénh. 

T. TORNATOR Fabr.—This species is subject to vary. I ob- 
tained an individual near the Rocky Mountains, so covered with 
short whitish hair as almost to conceal its color; it was destitute 
of the large black spot of the elytra. Two specimens occurred 
in Mexico, both of which were destitute of the same spot. It 


is the 7. tetropthalmus Forster.

666 BOSTON JOURNAL 


Of this genus are two species; the tornator F., and the can- 
teriator Drapiez, both of North America. The latter has re- 
ceived three or four names from as many different authors, bat 
as they are unaccompanied with descriptions, the above will of 
course, take precedence. 


HISPA Linn. 

H. arricornis.—Above yellowish; antennee, thoracic line and 
tip of the elytra, black. 

Inhabits Mexico. 

Body above yellowish-fulyous: head impunctured: antennee

scutel black : elytra serrate, with double series of punctures, and 
interstitial, slender, elevated lines; tip black-brown, not more 
than one-fifth of the whole surface of the elytra: pectus and 
postpectus with a lateral black vitta dilating behind: feet black : 
thighs fulvous at base: venter black, yellowish each side. 

Length more than one-fifth of an inch. 

This cannot be H. quadrata Fabr., which has the elytra mar- 
gined with purple. [197] 


CASSIDA Linn. 


(©. UNIPUNCTATA nob. Journ. Acad. Nat. Se. vol. iii. 

A variety of this species occurs in Mexico, of a smaller size, 
with sometimes a black, arcuated, transverse line behind the ab- 
breviated thoracic line. The inferior surface, in some specimens, 
is black, the feet varied with whitish, and whitish triangular 
lateral spots on the incisures of the venter ; in others the inferior 
surface is pale greenish-yellow, more or less varied with black, 
the spiracles black. It is an abundant species.

Inhabits Mexico. [198] 

Body dark green, somewhat metallic, punctured : head with an 
impressed angular line between the antennz: antennz honey- 
yellow, at tip fuscous: labrum and palpi honey-yellow: thorax 
irregularly, and in parts confluently punctured, particularly on 
the sides; on the disk the punctures are sparse: elytra with a 
cupreous tinge, and more or less arcuated and abbreviated series 
of punctures, including the whitish spots; spots unequal, more 
or less rounded, between twenty and thirty in number, yellowish- 
white, the largest one on the humeral margin and bilobate, two 
geminate ones at base, none on the sutural margin: wings carne-

Head punctured, sanguineous, beneath the antennz whitish ; 
vertex with an impressed dot: antennz fuscous, or blackish, 
basal joints whitish beneath: thorax sanguineous, punctured, 
with two indented dots: elytra densely punctured, with a common 
suture and vitta blue, the latter originating on the humeral tu- 
bercle and abbreviated before the tip: pectus ferruginous: post- 
pectus and venter black ; feet white. 

Length one-fifth of an inch. 

Distinguishable from other species by the indentations of the 
head and thorax, combined with the elytral vitte and irregular 
puncturing. 

The G. vittata Fabr. is common in Mexico. 


ALTICA Geoff.

Related to collaris Ilig., and collata Fabr., and particularly the 
latter, from which it may be distinguished by its blue elytra and 
immaculate face. A specimen was sent to me by Mr. Barabino, 
from New Orleans. [200 |

OF NATURAL HISTORY. 669 


Body pale yellowish: antenne blackish; three basal joints 
honey-yellow, with a black line above: vertex with a black spot 
thorax with two small dots, and an abbreviated line arranged tri- 
angularly, black, and a lateral, somewhat larger, oblique, oval, 
indented black dot: scutel black: elytra impunctured, destitute 
of striz; a common sutural black vitta, another in the middle, 
somewhat narrower than the intervening portion, and a submar- 
ginal one: pectus yellowish : postpectus and venter black, the 
latter with yellowish margins to the segments : feet honey-yellow : 
tibize and anterior and intermediate thighs with a black line. 

Length one-fifth of an inch. 

Very closely allied to A. alternata Mlig., the form and propor- 
portion of the elytral vitta being the same, but that species is 
somewhat larger, and is altogether destitute of the lateral thora- 
cic impressed dots. 


3. A. CERACOLLIS.— White ; head black, elytra violaceous. 

Inhabits Mexico. 

Body white, impunctured; head black, with an elevated line 
below the antennz : antenne black, second and third joints white, 
with a black line above: thorax immaculate: elytra violaceous, 
burnished ; tarsi and tips of the tibize black. 

Length less than one-fifth of an inch. 

Resembles the A. collaris Illig., (aanthomelas Dalman,) but 
is much more closely allied to A. collata Fabr. It is somewhat 
doubtful if it be a distinct species; but as I possess specimens 
of the latter from Pennsylvania, Missouri [201] and Florida, all 
correspond in having green elytra, white front, and other dis- 
tinguishing traits, I have ventured to assign it a distinct name. 


EHROTYLUS Fab.

Much larger than L. Mozardi Latr., and with a proportionally 
shorter thorax, in these respects corresponding with L. puncti- 
collis nob., which it equals in magnitude, but has an immaculate

it certainly resembles very closely the stigma [203] nob., so

but it is more than twice the size of either of those insects, and 
may also be distinguished from the former, by the superior mag- 
nitude of the rufous spot of which the form is transversely oyal, 
whilst that of the stigma is orbicular.

Descriptions of new North American HYMENOPTERA, and Observations 
on some already described. 


Communicated Feb. 1835. 
Family TENTHREDINETA. 


ACORDULECERA Say. 

Artificial character —Antenne filiform, 6-jointed, short ; radial 
cellule one; cubital cellules three, the second smallest. 

Natural character—Antenne six-jointed ; first and second 
joints subequal, the second larger ; third joint longest but equal 
to the following ones in diameter; remaining joints gradually 
shorter; terminal joint not longer than the second: mandibles 
arcuated, acute; a prominent tooth on their middle: labrum 
prominent and distinct: radial cellule rather large: cubital 
cellules three ; first elongated, as long [210] again as the second: 
carpus large : tibize with one pair of spines at tip. 

Obs. The family of which this new genus is a member, was 
~ divided by Leach into nine Stirpes, all of which have nine or 
more joints in the antennz excepting the first, second, and fifth. 
Of these, two genera only, have 6-jointed antenna, viz., Zarca 
and Perga Leach ; but both have clavate antennz and in many 
respects are at variunce with the characters of the present insect. 
In alater work, the ‘“ Entomologische Monographieen,”’ by Dr. 
Klug, which that author has done me the favor to send me, are 
the two new genera Pachylosticta and Syzygonia, both of which 
have clavate antenne, and therefore, like the preceding, cannot 
possibly include our insect. 

A. porSALIS.—Black ; hypostoma, a base of the tergum and 
feet whitish. 

Inhabits Indiana. 

¢ 9 Black, with minute whitish hairs; nasus, labrum and 
mouth white: mandibles rufous at tip: thorax with the anterior 
segment, curving to the base of the wing, white; line of the in- 
sertion of the wings white: wings a little dusky; nervures fus-

at tip: venter more or less yellowish-white, dusky or blackish at 
tip: feet and coxe whitish-green. 

Var. a. Feet and part of the costal rib green ; scutel and pos- 
terior portion of the stethidium whitish. [211] 

Var. 6. Thorax and abdomen entirely black. 

Length three-twentieths of an inch. 

This insect is common. 


HYLOTOMA Latr. 

1. H. scurerrara.—Fulvous ; head and thorax, excepting 
the humerus and scutel, blackish. 

Inhabits United States. 

@ Body reddish-yellow: head blue-black : thorax blue-black ; 
each side before the wings, including the superior portion of the 
pleura, reddish-yellow : scutel elevated, bright reddish-yellow : 
metathorax with two oblique, oblong, white spots: wings dusky 
violaceous : pectus, neck, incisures of the stethidium (and feet?) 
blue-black : anal segments at tip black. 

Length nine-twentieths of an inch. 

Ido not remember in what part of the Union I found this 
species. The feet in the specimen are mutilated. 

2. H. cALcANEA.—Blackish ; thorax yellow; tarsi whitish at 
base. 

Inhabits United States. 

Violaceous black : thorax with the anterior superior portion of 
the pleura yellow; suture of the anterior segment, or collar, 
blackish: wings dusky violaceous: tarsi at base white. 

Length less than seven-twentieths of an inch. 

I have also lost the particular locality of this species. They 
do not correspond with either of the species described by Dr. 
Leach. [212] 

ATOMACERA Say. 

Generic character.—Body rather short : antennee with but three 
obvious joints; in the male ciliated: cellules, one radial, unap- 
pendiculated ; three or four cubitals, the dividing nervure of the 
first and second being obsolete: tibia destitute of a spine in 
their middle.

Obs. The name of Cryptus, applied by Jurine to one of his 
genera, has been previously appropriated by Fabricius to a genus 
of Ichnewmonides, and is altogether synonymous with Hylotoma 
of Latreille, which is the anterior designation. It includes spe- 
cies of at least three genera, all of which are distinguished by 
tri-articulate antennz. It may be thus divided, with modified 
characters. 


Hytoroma Latr.—Radial cellule appendiculated : four poste- 
rior tibize with a spine on their middle. 
HT. roszx F. 


ATOMACERA nob.—Radial cellule simple ; tibize destitute of a 
spine on their middle. 


Cryptus Jurine (by error.)—Antenne of the male biparted : 
tibize destitute of a spine on their middle. 
C. furcata F.C. Klugii, Leach, Xe. 


1. A. DEBILIS.—Black ; tibia whitish. 

Inhabits Indiana. 

% Body black, polished : antennee, cili# longer than the trans- 
verse diameter of the antenne: mouth dull piceous: wings fuli- 
ginous, a little paler at tip; first and [213] second cubital cellules 
confluent: tibize, anterior pair dull pale yellowish. 

Length three-twentieths of an inch. 


2. A. CELLULARIS.—Black ; abdomen rufous. 

Inhabits Indiana. 

Q Body black, polished : antenne distinctly and rather densely 
ciliated with hairs, which are a little shorter than the transverse 
diameter of the antenne: nasus, labrum and palpi whitish: 
wings dusky violaceous ; cubital cellules three; the second very 
small, hardly one third the length of the first, and but little 
wider at its tip than at its base: abdomen entirely yellow-ru- 
fous: feet, cox, trochanters and small base of the tibie, whitish ; 
anterior pair of tibiz dull whitish. 

Length less than one-fourth of an inch. 

Much smaller than Hylotoma abdominalis Leach, which it ~ 
probably resembles.

THULEA Say. 


Artificial Character.—Antenne six-jointed ; last joint clayate. 
Radial cellule one. Cubital cellules three. — 

Natural Character.—The antenne are rather short, decidedly 
clayate ; first joint very short, not longer than broad; second 
joint at least as long again as the first and somewhat more ro- 
bust, cylindrical; third rather longer than the Ist and 2d to- 
gether, much more slender, cylindric, hairy; fourth minute, 
shortest ; fifth about the length of the third, subcylindric, [214] 
naked ; sixth slightly longest, nearly equal to the 3d and 5th, a 
little dilated towards the tip ; scutel large. 

Observations. —This is distinguished from the genera into 
which Leach has divided Cimbex Fabr. by the number and con- 
struction of the joints of the antenne, combined with the wing 
cellules. It corresponds with Clavellaria in its one-jointed club, 
but has one joint more in its antenne, and only one radial cellule. 
It agrees with Zarea in the number of the joints of the antenne, 
but not in the number which constitute the club, nor in the 
number of radial cellules. With Perga it is related by the com- 
parative magnitude of the scutel, and the number of joints of 
the antenne, but differs remarkably in the proportions of the 
latter, as well as in the number of cubital cellules. Pachylosticta 
of Klug has a one-jointed club, but one joint less than the pre- 
sent genus, and two radial cellules; and Syzygonia of the same 
author, with a one-jointed club, has appendiculated radial cel- 
lales. 


T. nriGRA.—Body black: nasus and labrum green : spot before 
the wings, wing-scale and feet yellowish-green. 

Inhabits Mexico. 

Length to the tip of the wings three-twentieths of an inch. 

The smallest species I have seen of this family with clavate 


antenne. [215]

second joints of the antenne short, equal. 

Inhabits Indiana. 

%& Body short, robust, black, polished : antenne rather robust,

This is undoubtedly much like the X. camelus Linn., which, 
however, is destitute of spots on the disk of the thorax, the wings 
are clouded towards the tip, and there are but six lateral spots on 
the abdomen, the ultimate segment being immaculate.

punctured : feet, two anterior pairs piceous. [224] 

Length about one-fifth of an inch. 

I agree with Leach in the propriety of separating this group 
from Hvania. In addition to the great dissimilarity of the neu- 
ration of the wings, the proportional length of the posterior feet 
and of the antenne is quite different.

generally interrupted into two distant dots: thighs at base and 
tip, tibiee at tip, and tarsi, with a slight tinge of piceous: an- 
tenne annulate. [230] 

* Hypostoma and mouth yellow : feet with the thighs at base 
and tip, tibize at tip and base of the joints of the tarsi, dull yel- 
lowish. 

Length from nine-twentieths to three-fifths of an inch. 

May be distinguished from brevicinctor, unifasciatorius, and 
otiosus nob. by its black scutel; and from morulus aud malacus 
nob. by having a yellow line before the wings. I have found it 
in Pennsylvania, Indiana and Louisiana.

It varies in having the seutel black and the feet entirely black. 

Another variety has the tibie and tarsi ferruginous. My 
largest specimen was sent to me by Dr. Harris.

OF NATURAL HISTORY. 691 


Body pale ferruginous yellow: antennx black, ferruginous at 
base, and with white semi-annulus on the middle: scutel with its 
basal angles connected with the thorax by an elevated line: 
wings yellowish, a black band before the middle, another beyond 
the middle, connected in the form of av with the black apical 
margin ; central cellule pentangular, its basal and apical lines being 
nearly Genellel; ; inferior wings with a dot in the middle, and 
apical margin blackish: tergum with the third segment dusky 
or black at its base: oviduct black, nearly as long as the abdo- 
men: posterior tibie blackish at tip. 

Length less than three-fifths of an inch. 

The remarkable resemblance which exists between the present 
insect and the bifasciatus nob. in point of color, renders it neces- 
sary, in order to prevent mistake, that we should observe that in 
the bifasciatus the oviduct is not half the length of the abdomen, 
and the central cellule of its wing joins the radial cellule in an 
acute angle, its basal and apical lines being confluent at the 
point of the junction with it.

at tip.

2 Body rufous, almost sanguineous, opake : antenna, excepting 
the two basal joints, black with a white annulus in the middle ; 
wings hyaline, a blackish band on [235] the middle, abbre- 
viated before ; another blackish band nearer the tip abbreviated 
behind; tip, margin dusky ; second cubital cellule pentangular, 
its basal and terminal lines not parallel: metathorax a little ru- 
gose each side with a short compressed tubercle each side on the 
declivity: tergum with the basal segment polished ; third seg- 
ment black at base: oviduct nearly as long as the abdomen: 
pleura with the incisures punctured : posterior tarsi a little paler.

The male is much smaller than the female. I obtained a fe- 
male from a follicle of the common folliculate [236] Linnzan 
Bombyx, with transparent wings, which were extremely abun- 
dant a few years since in Maryland, causing much apprehension 
for the safety of the trees of their choice. Some of them were 
obtained for me by my friend Mr. Gilliams, for examination, 
when I described them under the name of hyalina, but did not 
publish the account.

pentangular, the side of the radial cellule much the smallest ; 
two bullz and recurrent nervures each with one: metathorax 
with the sutures black; scutel rounded : abdomen clavate, faleate, 
gradually narrowed to the base, somewhat polished ; posterior 
margins of the segments obsoletely yellowish ; base of the seg-

pair at tibia and tarsi paler than the thighs; posterior coxe 
nearly as long as the thighs. 

Length three-fifths of an inch. 

This insect differs somewhat in appearance from its congeners. 
The form of the abdomen, excepting that it is not compressed, 
the fact that it originates higher upon the metathorax than the 
others, and the elongated posterior coxa, give it a little the air 
of a Fanus, but the numerously jointed antennie place it in this 
family. [ 237 ] 

11. CO. nuncrus.—Black ; abdomen excepting the base and 
tip rufous. 

Inhabits Pennsylvania. 

Body black ; palpi white, blackish at tip; antenne 9 a long

elevated line before the bi-foveolate scutellar groove: wings, 
radial cellule rather wide and short: cubital cellule pentangular, 
sides subequal, angles at the radial cellule nearly rectangular : ab-

OPHION Fabr. 

1. O. purGATUS.—Honey-yellow ; two opake dots in the first 
cubital cellule. 

Inhabits Indiana. 

Body pale honey-yellow, somewhat sericeous: antenne rather 
longer than the body: orbits yellow, dilated before so as to oc- 
cupy the greater part of the hypostoma : ocelli large, prominent: 
wings hyaline; stigma slender; first cubital cellule with two 
opake, subtriangular spots; second cubital cellule none: meta- 
thorax with a single, raised, rectilinear, transverse line, near the 
base. 

Length about seven-tenths of an inch. 

This is much like an insect sent me by Mr. Winthem [239] 
as the ramidulus Fabr., which has also opake wing-spots, but is 
black on the tip of the abdomen. The dilineatus nob., may be 
distinguished from this species by having many raised lines on 
the metathorax and by being destitute of the opake wings-spots. 
The sexes are similar in color, and both have the opake wing- 
spots, which is not the case in Mr. Winthem’s specimens of 
ramidulus.

much compressed: basal joint cylindrical; second segment as 
long as the first, or a little longer, compressed towards the tip: 
anterior pair of the feet yellowish before : intermediate pair with 
a line before and base of the tibize yellowish : [248] posterior pair 
with the tibia, excepting the tip, and the tarsi, excepting the 
terminal joint, fulvous-yellow. 

Length nearly one inch. 

Resembles flavicornis nob., which, however, has the first seg- 
ment of the abdomen considerably longer than the second. It is 
also allied to morio Fab., but that species is described to have 
the wings blue, tipped with brown, and the legs black, the ante- 
rior ones testaceous.

tibize at tip and annulus near the base, and posterior halves of the 
tarsal joints black.

the impressed lines of the tergum are very oblique, and the 
wings are destitute of the small second cubital cellule.

1. B. pectinator.—Black ; abdomen yellowish ; wings black- 
ish; cellules regular. 

Inhabits United States. 

Head rather large and robust, concave behind at the neck; 
rostrum not prominent; thorax with the dorsal sutures dilated 
and containing very obvious transverse lines ; the transverse su- 
ture at base of the scutel with five elevated lines; wings dark 
violaceous; second cubital cellule shorter and smaller than the 
first, quadrangular; nervure forming the radial cellule rectili- 
near ; oviduct exserted, black. 

Length 9 to tip of wings nearly two fifths of an inch. 

I am not certain whereabout this insect was captured, but I 
think I obtained it in the N. W. Territory when engaged on the 
northern expedition with Major Long. 

It resembles the populator, but the rectilinear form of the 
nervure of the radial cellule places it nearer rugator nob., and 
initiator F.; from the former it is distinguished by the more sim- 
ple surface of the tergum, and fromthe latter by the much shorter 
second cubital cellule.

OF NATURAL HISTORY. 705 

Rostrum distinct : head piceous; antenne black ; [252] tho- 
rax polished ; wings purplish-fuliginous, with three or four ob- 
solete, small, white spots; cellules regular; tergum with numer- 
ous longitudinal, elevated lines on each segment; first segment 
with the lines transverse and interrupted by a large, elevated 
oval lobe on the disk, which has a longitudinal line and irregu- 
lar ruge ; the lateral edge elevated ; second and third segments 
with an oblique indented line at base each side; oviduct two- 
thirds the length of the abdomen, black, clothed with short hairs ; 
feet piceous-black. 

Length 9 three-tenths of an inch. 

The remarkable appearance of the tergum readily distinguishs 
this species from populator nov., which it resembles. It has 
a general resemblance to B. initiator Fabr. 


3. B. ueBetor.—Black; head, thoracic lines, tibiae and base

piceous, oblique lines confluent at the middle and terminating in 
a spot each side of the scutel; wings dusky, nervures black ; 
stigma rather large; nervure from the stigma, oblique to the 
second cubital ; abdomen depressed, oblong-ovate ; cox, knees 
and base of the tibize, yellowish-white : oviduct shorter than the 
abdomen. 

% Abdomen whitish at base. 

Length nearly one-tenth of an inch. 

The antennz of the male are twenty-two-jointed and those of 
the female are short, more robust, fourteen-jointed. The short, 
thoracic piceous lines have sometimes a cruciform appearance by 
being continued around the scutel. [253]

on the disk or towards the tip: pleura with a blackish line be- 
hind the wing: pectus blackish on the disk: feet with the tarsi 
dusky at tip. 
@ Oviduct half as long as the abdomen. 

Length to the tip of the wings less than three-twentieths of 
an inch. 

Much like hebetor, but is somewhat larger and more robust ; 
it may be distinguished at first by its lighter color. As in that 
species the first cubital cellule is wider by one-third than the 
second at their junction, and the latter is hardly as long as the 
first, in either sex. 


5. B. arcurator.—Honey-yellow ; antennze, terminal joint 
of the tarsi and oviduct, black.

? Body honey-yellow, somewhat polished: antennz black : 
mandibles piceous : hypostoma with a transverse, dilated inden- 
tation: stemmata blackish: thorax immaculate: wings very 
slightly tinged with dusky; nervures blackish ; stigma yellowish

than the first, and nearly as wide at their junction : tergum of a 
yather paler yellow than the thorax, and opake with minute 
punctures or granules, oblong-oval : oviduct black, half as long 
as the abdomen : tarsi, terminal joint blackish. [254] 

Length to tip of wings over three-twentieths of an inch. 

Of the same general habit with Achetor, but is considerably 
larger, and may be known at once apart from it, by the equality, 
at their junction, of the 1st and 2d cubital cellules, by the punc- 
tured tergum, Kc.

ish: thorax dull fulvous, with three dilated black lines, of which 
the middle one is abbreviated before the middle: metathorax

towards the tip; lateral edge dusky ; first segment at tip bisin- 
uate or three-angled : feet paler: thighs a little dusky.

thorax black: wings hyaline; nervures pale brownish ; stigma 
yellowish at base ; 2d cubital cellule shorter and narrower than 
the first: tergum elongate sub-obovate, black at base, this color 
extending paler on each side; middle of the disk towards the 
base [255] pale yellow extending on the tip of the first segment, 
which is sub-bisinuate or slightly three-angled ; second segment 
as well as the first with an elevated line: oviduct not exserted 
beyond the tip of the abdomen, black. 

% Third and following segments of the tergum annulate with 
black ; no elevated line on the tergum, nor three-angled appear- 
ance of the tip of the first segment.

pressed punctures, which on the front are transversely confluent 
into minute ruge : mouth obscure piceous : antenne obscure pl- 
ceous, black towards the tip: thorax somewhat tinged with san- 
guineous, and with three abbreviated, blackish vitte; behind

the intermediate vitta is a rugous space, with a slightly elevated 
line : wings hyaline ; nervures and carpus blackish ; cubital cel- 
lules three; metathorax rugous, with an elevated line : abdomen 
longitudinally rugous, oblong; with three larger segments, de- 
creasing in length; and three smaller ones at tip, taken together 
hardly longer than the third: pectus in the middle black. 

Length one-fourth of an inch. 

The magnitude of the three basal segments of the abdomen is 
remarkable in this species. 


9. B. TRANSVERSUS.—Granulated ; nervure from the stigma 
nearly transverse. 

Inhabits Indiana. [256] 

Body densely punctured or granulated ; blackish-piceous: an- 
tenn, mouth and feet honey-yellow: wings hyaline ; nervures 
brown; stigma large; nervure from the stigma to the second 
cubital cellule nearly transverse, so as to make the three angles 
at its contact, equal : tergum dull honey-yellow at base ; first seg- 
ment with two prominent, parallel lines; second segment oecu- 
pying three-fourths of the whole surface: oviduct shorter than 
the abdomen. 

Length over one-twentieth of an inch. 

The whole surface has a minutely granulated appearance, and 
the nervure from the stigma is more than usually transverse, 
having but a very slight obliquity. In having but two principal 
segments to the abdomen, this species approaches the genus 
Nigalphus, but the venter is not deeply vaulted as in that genus.

not polished ; paler than the thorax, with minute, prostrate hairs; 
second segment with an indented dot each side: oviduct black, 
as long as the abdomen: tarsi, terminal joint blackish.

Length one-fourth of an inch. 

This species and the following differ from the type of the 
genus Bracon in the from of the radial and third cubital cellules, 
in consequence of the arcuation of the separating nervure. 

It is much like populator nob., but among other characters it 
may be distinguished by the yellowish carpal spot and costal 
neryure, which are always black in the populator.

Length 4 one-fifth of an inch. [260] 

The cubital cellules are but two, the second transverse nervure 
being entirely wanting, and the nervure forming the anal side of 
the cubital cellules is very slender ; the other nervures being 
quite robust. If the genera throughout this order, are not to be 
divided as in the Tenthredinete, I would propose the separation 
of this and the following species, under the generic name of 
Aliolus. 

The character of the abdomen agrees with this genus; but the 
neuration of the wings seems to agree rather better with Micro- 
gaster.

The much elongated stigma and the small spot which precedes 
it, being larger and more separate than usual, readily distinguish 
this species.

Stethidium black : feet honey-yellow : wings, at base and stigma 
yellowish; a blackish band upon the two [ 265 | discoidal cel-

descending nervure to the small second cubital and continued 
dilating to the anal margin, where it is almost confluent with the 
other band ; terminal third hyaline ; inferior wings blackish, yel- 
lowish on the basal third, this color extending along the costal

Jurine, this species as well as the following belongs to this genus, 
on account of the undivided abdomen; still, however, the denta- 
tas F., which has two distinct sutures on the tergum, is also re- 
ferred by some modern naturalists to this genus.

This species is remarkable in having but a very short, bifid 
process extending from the tip of the abdomen. ‘The sexes are 
not well understood. Jurine says that the antenne have the 
same number of joints, and that the pointed valves which termi- 
nate the abdomen are nearly alike in both sexes. But the pre- 
sent insect leads me to suppose that the male has not been 
hitherto known. At the extremity of its abdomen are two very 
short, parallel filiform processes, which are probably character- 
istic of the male sex in this genus. It seems, therefore, possible 
that the pallidus may prove to be of the same species as [ 279 ]

P. caudatus nob., notwithstanding their great apparent difference. 
But this cannot be determined without more specimens, and a 
better acquaintance with them both. 

Since the above was written, I have obtained many specimens 
of this species, all corresponding in apparent sexual character, 
excepting that in some the second joint of the antennz is so 
far immersed in the first, as to be hardly visible; still as it is 
not, in any, much exserted, this character is probably dependent 
on the greater or less degree of contraction in drying.

Although the wings entitle this species to a place in Jurine’s 
Psilus, yet the antennz are entirely different from those of the 


type P. elegans, resembling considerably those of his P. antenna- 
Zus.

black, abdomen whitish. 

Inhabits Indiana. 

Body black : antennx broken at the second joint; first joint 
one-fourth the whole length, whitish: second joint obconic: 
terminal joint ovate-fusiform, longer than the three preceding 
joints together ; wings very deeply ciliated: abdomen whitish, 
particularly at base: tarsi whitish.

A. FERVENS Drury, vol. iii. p. 58, pl. 42, f.3.—I obtained a 
female of this species in Mexico, and on comparison with an in- 
dividual of the cephalotes sent me by Dr. Klug, I find it to be a 
closely allied species. The color of the wings and their neura- 
tion are the same ; but the body is more hairy or downy, and its 
brown color is not so deep, (the color is much too black in my 
copy of Drury, agreeing better with the cephalotes, than with 
Drury’s description.) The head is not so large, so deeply in- 
dented above, nor so acute at the posterior angles. The impressed, 
longitudinal line on the anterior part of the thorax, so distinct 
in cephalotes is not, or is scarcely visible in fervens. Judging 
from these two specimens, I am convinced that the fervens ought 
to be admitted into the modern books as a distinct species.

This is called the “little yellow ant,” and is frequently found

like the puncture of a very fine needle. I placed a piece of 
meat on a window board frequented by these little depredators ; 
it was soon absolutely covered by them, and thus enabled me to

each side. 

Inhabits Indiana. 

% Body black, polished, with small pnnctures: nasus, labrum, 
tip of the basal joint of the antennz, two spots between the an- 
tenne and base of the mandibles yellow : collar on the anterior 
margins interrupted in the middle and on the posterior margin, 
yellow: thorax with a spot in the middle emarginate before, yel- 
low: metathorax, a transverse yellow spot near the scutel and an

obscure yellow, longitudinal spot each side at tip: tergum with a 
perlaceous iridescence : on each segment a slender yellow [301] 
band on the posterior submargin, a little undulated obtusely on 
its anterior edge, not abruptly emarginated on each side; on the 
anterior submargin of the segments an impressed transverse line : 
pleura, a small yellow spot beneath each wing ; wings hyaline, a 
slightly dusky margin at tip : feet, coxe with a yellow spot: tarsi, 
excepting their tips: thighs at tip or a line above, and anterior 
pairs of tibia yellow: venter five spotted each side. 

Length from three-fifths to seven-tenths of an inch. 

This is so much like M. subulata nob., that it is not without 
much hesitation that I give it as distinct. It is, however, 
much larger and more robust, and the form of the bands 
of the tergum is different; those of the subulata being abruptly 
notched each side of the middle as in the va/vulus Fabr., whereas 
in the bands of the present species, instead of the abrupt notch, 
is an obtuse and dilated undulation of the edge. 

A variety occurs in Missouri, of which the wings are yellow- 
ish, and the second recurrent nervure is confluent with the divi- 
ding nervure of the second and third. cubital cellule.

POMPILUS Fabr. Latr. 


1. P. caLiprerus.—Wings bifasciate; antenne and feet 
honey-yellow. 

Inhabits Indiana. 

Body black, polished, slightly pruinose : antennze honey-yellow, 
a little dusky towards the tip: nasus, at tip, mandibles and palpi 
honey-yellow: wings hyaline, with a blackish band on the mid- 
dle and a much broader one crossing the second and third cubital 
cellules ; the latter hardly reaches the anal margin ; basal series 
of transverse nervures dislocated at the externo-medial nervure: 
feet honey-yellow ; tarsi with the ultimate joint blackish; inter- 
mediate and posterior pairs of feet more or less varied with 
blackish. 

Length three-tenths of an inch. 

A very pretty species, of which [ have as yet obtained but 
two specimens. It is probably allied to the bifasciatus Fabr. 


2. P. ancHITEcTtuS.—Dark purple ; wings hyaline. [303] 

Inhabits Ohio. ; 

9 Body dark bluish-purple, somewhat hairy: head black in 
front, with short, dense, yellowish-cinereous hair: mandibles at 
tip piceous: wing-scale dark piceous: wings hyaline, nervures 
blackish: second and third cubital cellules not unusually con- 
tracted at the radial cellule, but almost equal in that part, feet 
black : tergum, anal segment polished. 

Length about three-tenths of an inch. 

This insect forms neat mud nests under prostrate logs and 
stones. They consist of short cylinders, agglutinated together 
alternately, and each composed of little pellets of mud, com- 
pressed, or rather appressed to each other. When these are 
adjusted to their places on the edge of the cylinder, each has a 
fusiform shape and the slender end of one laps over that of 
another, and the convex part of the pellet of the succeeding 
layer is placed against this duplicature so as to restore the equal- 
ity of the edge. This arrangement gives the surface an alternate 
appearance.

The basal series of transverse nervures is very slightly dis- 
located. 


3. P. BiguTTaTus Fabr.—The individual described by Fabri- 
cius appears to be a female. Coquebert gives its length at nine- 
twentieths of an inch, but it sometimes exceeds half an inch in 
length. The male is over three-tenths of an inch in length ; it 
is destitute of the anterior white striga of the thorax, and the tip 
of the tergum has a white reflection; the posterior half of the 
metathorax also has a white reflection. The basal series of trans- 
verse nervures is not dislocated, in this species.

ond and third cubital cellules a little narrowed at the radial cel- 
lule, particularly the latter, which is less than two-thirds the 
length of the second cellule, in that part; basal series of trans- 
verse nervures not dislocated ; metathorax with a very slight re- 
flection of purplish, and without any impressed line; the poste- 
rior edge obviously reflected ; tergum with a distinct purplish re- 
flection ; beneath black; in a favorable light a very slight pur- 
plish reflection may be perceived on the thighs. 

Length two-fifths of an inch. 


5. P. 5-Noratus.—Tergum on the second segment with two 
white spots; third segment with a white interrupted band. 

Inhabits Indiana. 

9 Body black; head with a slight white reflection before ; and 
a very slender white line on the posterior orbit: wings on the 
apical margin black; basal series of transverse nervures not dis- 
located ; tergum with a white dot each side before the middle, on 
the second segment: third segment with a white, interrupted 
band at base, on the fourth segment at base is an obsolete, whit- 
ish spot each side, sometimes wanting ; anal segment with a white 
spot at base. 

Length two-fifths of an inch. 

Resembles biguttatus Fabr., but is distinguished by the two or 
four more white spots on the tergum, as well as by the white spot 
on the anal segment.

entering the radial cellule in a much arcuated direction, so as not 
to form an angle with it; third cubital cellule not much con- 
tracted anteriorly ; basal series of transverse nervures widely dis- 
located, that portion which is between the externo-medial and 
anal nervures is equal to the length of the dislocation ; abdomen

MERIA Jur. 


M. costatTa.—9Q Black; tergum with yellow bands and two 
spots. 

Inhabits Indiana. 

Body black: head above the antenne with a transverse line, 
slightly interrupted in the middle, an orbital line, and short line 
behind the eyes, yellow: mandibles piceous: thorax with two 
transverse spots before, a small, triangular one above the wing- 
scale, a transverse one behind the scutel, and a bilobed one each 
side behind, yellow ; each side of the middle of the thorax are 
two abbreviated, somewhat oblique, impressed lines : metathorax 
with a double yellow longitudinal side and obvious transverse 
ruge: pleura with a triangular spot under the superior wings, 
a small oblique line over the intermediate feet, yellow: wings 
with a brown costal margin: tergum [362] with a yellow band 
on the middle or before it, of each segment, excepting the last ; 
the second band interrupted into two transverse, oval spots : 
venter with a longitudinal, lateral spot on the second segment 
and a transverse lateral one on the third, yellow; tarsi and in- 
termediate and posterior pairs of tibie piceous; a yellow spot 
on the posterior coxe. 

Length half an inch. 

Vara. Middle of the thorax with a small double yellow spot. 

The observations which I had occasion to make relative to the 
generic affinities of Plesia marginata nob., are exactly applica- 
ble to this species. It agrees precisely with Jurine’s character 
of Plesia, but differs from Mizine Latr. by having the mandibles 
entirely destitute of teeth, a character which it has in common 
with Meria Ill., but the form of its wing-scale, will not admit of 
its being referred to the latter genus; [ have, however, in this 
instance, been guided by the characters laid down by Latreille 
in the Régne Animale (first Edition).

3. M. cotztaris.—Collar with an interrupted band and two 
spots yellow. 

Inhabits Indiana. 

Body black : head with two spots above the antennz, frontal 
orbits, and dilated line behind the eyes, yellow: mandibles dark 
piceous, black at tip: collar with an interrupted band on the 
posterior margin and two spots before yellow: thorax with a 
small yellow spot above the wings: wing-scale dull honey-yellow 
with a yellow spot: wings yellowish, fuliginous, dusky on the 
costal margin towards the tip; behind the scutel is a transverse 
[363] yellow line: metathorax somewhat sericeous, without any 
appearance of rugee, and with two yellow longitudinal spots : ter- 
eum with a somewhat varied reflection; first and second seg- 
ments with a lateral yellow spot, (those of the former probably, 
in some specimens, obsoletely connected) ; third and fourth seg- 
ments with a lateral basal yellow spot, connected by a slender 
line ; fifth segment with an obsolete yellow lateral spot: pleura 
with a yellow spot under the anterior wings : feet, anterior knees 
and tibial dilated line yellow; intermediate and posterior tibiz 
and all the tarsi ferruginous : anal segment above minutely line- 
ated, and at tip, dull ferruginous. 

Length over three-fifths of an inch. 

This species is larger than costata nob., which it much resem- 
bles, but may be distinguished by the sericeous appearance of 
the metathorax and the absolute destitution of rug on that part ; 
in the costata also, the lateral spots of the metathorax are double. 


SCOLIA Fabr.

second receiving two recurrent nervures, and with an abbreviated 
nervure proceeding from its base towards the tip of the wing: 
tergum violaceous-black; second and third segments fulvous, 
with a narrow basal and terminal black margin ; beneath black : 
venter slightly tinged with violaceous: thighs not remarkably 
robust. 

Length % over one inch and one tenth.

2. 8. puBIA.—Black; abdomen ferruginous behind with two 
yellow spots on the third segment. 

Inhabits United States. 

Body black: head and thorax immaculate : wings dark violet 
blue: cubital cellules two, with no appearance of more than 
one recurrent nervure: abdomen, first and second segments 
black; remaining segments ferruginous; more hairy, somewhat, 
than the others; the third segment, however, more or less tinged 
with blackish and with two transversely oval, a little oblique, 
bright yellow spots. 

- Length four-fifths of an inch. 

A very fine, though rather common species, in various parts of 

the Union. 


3. S. CONFLUENTA nob. Western Quarterly Reporter.—I think 
it highly probable that Drury’s fig. 5, pl. 44, vol. i, is intended 
for this insect. I was deterred from quoting this figure in con- 
sequence of its yellow head and four-banded tergum; but the 
head is truly, on its front and base, covered with yellowish 
cinereous hair, as well as the anterior part of the collar; this 
may agree with Drury’s observation that the “head is of a pale 
yellow, in front” and “the neck is hairy and of a lemon color.” 
The species also probably varies in having four yellow bands. 
Drury’s figure is that of a female, and my specimen agrees with 
it in Having an immaculate thorax and scutel, as in the fossulana 
Fabr., which I believe to be in reality the female of this same 
species, and of course the same as that of Drury; whereas he 
quotes Drury’s figure as that of radu/a F. which appears to be 
the male, if I may judge by the “ thorace maculato” and other 
corresponding characters. I have no index to the first volume 
of Drury, but Fabricius quotes the figure as [365] Sphex plum- 
pes Drury. If this be correct, Drury has the priority, and the 
name and synonyms, will stand thus :

Inhabits Indiana. 

Antennze honey-yellow; first joint, bright-yellow: labrum yel- 
low, black at base: Lypostoma yellow, with a quadrate spot and 
incisures black: orbits dilated, yellow, interrupted above: tho- 
rax impunctured ; margin of the anterior segment all around, 
longitudinal spot each side of the scutel and transverse spot be-

low, posterior band clavate each side on the pleura: wings fuli- 
vinous, particularly on the cubital cellules and tip: abdomen fer- 
ruginous, varied with obsolete yellow and black bands ; and with 
two yellowish spots on the first segment: pleura with a spot be- 
hind the wings and a larger one over the intermediate feet, yel- 
low: coxee varied with yellow: thighs honey-yellow, black at 
base: tibiee honey-yellow, yellow at base: tarsi yellow.

Closely allied to fasciata nob. but the thorax is not distinctly 
punctured, the wings are dusky, &c. [366]

solete hyaline spot or band: metathorax dull silvery; abdomen 
rather slender towards the base; second segment, excepting on 
its posterior margin, fulvous; anal segment white: posterior

BEMBEX Fabr. Latr. 


1. B. Lonarrostra.—Rostrum extending beyond the inser- 
tion of the intermediate feet ; superior: wings with the marginal 
and last submarginal cells divided by a very distinct space. 

Inhabits Mexico. 

Body black, with short, dense, white hair: antenne tinged 
with piceous; first joint white beneath: anterior orbits dull 
white : nasus whitish, with two black spots: tergum white, with 
a bilobate, black spot at base: rostrum honey-yellow; extending 
nearly to the origin of the posterior feet: collar, anterior and 
posterior margins white: [367] thorax with a very small ful- 
yous, abbreviated line each side of the middle, and a small, 
double, fulvous spot behind the middle: scutel with a white 
lateral spot : metathorax with a white line at base and an oblique 
one each side towards the tip: tergum varied with yellow and 
black or green and black; the posterior margins of the segments 
dullrufous ; about four distinct black spots : feet honey-yellow : 
thighs black beneath : tarsi paler: venter honey-yellow, with a 
black spot before the anterior spine. 

Length from seven-tenths to four-fifths of an inch. 

With the short maxillary palpi and the one-toothed mandible 
of Bembex, this insect has the radial and last cubital cellules as 
widely separated at their tips as in Monedula. The proboscis is 
not folded, but extended horizontally beneath the body. These 
characters may justify the formation ofa distinct genus, or at 
least of a division, under the name of Steniolia. 


2. B. rascrata Fabr.—A male in my cabinet has six bands 
upon the tergum and two spots on the ultimate segment: the 
first band is double the width of that of the female, and is inter- 
rupted by a very small space only ; second band not interrupted, 
but its two lunules are so continued as to inclose two black spots ; 
third band with the lunules not or hardly interrupted ; fourth 
and fifth bands interrupted ; sixth band entire, undulated: spots 


on the ultimate segment, orbicular; the female has but five 
bands.

mandibles, pale yellow: thorax, posterior margin of the collar, 
abbreviated line over the wings, and wing-scale, yellow: scutel 
yellow: wings dusky, purplish-fuliginous, tinged with yellowish 
towards the base ; stigma small ; second cubital cellule obviously 
hexagonal: metathorax with two large, oblong-oval, yellow spots ; 
triangle at base destitute of small lines and with but a single 
impressed line: tergum, basal segment yellow; posterior narrow 
margin, and lobed spot on the disk communicating with the base, 
black : second segment yellow on the posterior margin, the yel- 
low rather dull and a little undulated on its inner edge: third 
and fourth segments with obsolete yellowish posterior margins: 
pleura somewhat silvery sericeous, with three almost confluent 
yellow spots in a line with the collar: feet pale, honey-yellow ; 
thighs and coxee, with more or less of black above. 

Length about half an inch. 

This is a large species. The character which Jurine mentions 
as common to all the species, of having behind the scutel a tri- 
angular space, in which parallel lines are sculptured, is so modi- 
fied in this species as to present the triangle with only a simple 
longitudinal impressed line.

of this author, who gives its native country as South America, on 
the authority of Mr. Smith and of the Museum of Mr. Lund, 
from whom and from Mr. Sebestedt he obtained an opportunity 
to describe a great number of Hymenoptera of that portion of our 
hemisphere; and but two species from North America. For 
these reasons I have been led to consider the albitarsa F. as 
South American; and as Latreille says that every thirty degrees 
of latitude exhibits a total change [374] in the insect productions, 
T give a new name to this species. 


2. T. cLAvATUS.—Abdomen at base slender and a little nodu- 
lous; wings at tip dusky. 

Inhabits United States. 

Body black ; head and stethidium with silvery reflection : wings 
hyaline, terminal margin dusky : abdomen clavate: the first and 
second joints petioliform, a little nodulous at their tips: posteri- 
cr tarsi white ; the terminal joint and base of the first joint black ; 
* with a spine on the posterior trochanter. 

Length about nine-twentieths of an inch.

OF NATURAL HISTORY. 757 


Var. «. Terminal joints of the tarsi blackish ; a yellow band 
at base of the second segment of the tergum. 

Judging from memory, as in the preceding instance, I suppose 
this to be the fuscipennis Beauvois, but not that of Fabricius, for 
the reasons there adduced. I may also state that this species 
does not correspond with Fabricius’ description in having “ale 
nigrz cyaneo parum nitide,” neither does it agree with “ Pedes 
- higri tarsis albis’”’ inasmuch as the posterior pair only are par- 
tially white. 

3. T. CARINATUS.—% Black: head and stethidium with sil- 
very reflection : a prominent, acute carina between the antenna, 
divaricating above the antenne into two carinz : antennz emar- 
ginate beneath towards the middle: wings hyaline: a slight tint 
of dusky at tip: tergum gradually attenuated to the base; three 
first incisures a little contracted; feet, anterior pair of knees, 
. tibize and tarsi yellowish ; intermediate knees and tarsi yellowish 
‘in the middle above dusky ; posterior tarsi obscurely yellowish 

towards the tip. 

Inhabits Indiana. 

Length three-tenths of an inch. [375] 

Remarkable by the carina of the head and the emarginate an- 
tenn. It is much smaller than the jigulus F., and its abdomen 
is formed as in that species. 


OXYBELUS Latr. 


1. O. EMARGINATUS.—% Black ; scutellar spine emarginate ; 
tergum 4-spotted. 

Inhabits Indiana. 

Body black, with a slight silvery reflection, particularly on the 
anterior part of the head: antennz dull yellowish at tip: wing- 
scale honey-yellow: wings hyaline: scutel with a dilated process 
widely emarginate at tip, and a lateral sublanceolate, decurved, 
acute, white one; tergum, first segment with a longitudinal, in- 
dented line, and a transverse, abbreviated, white line at tip each 
side; second segment also with a similar line: tarsi pale honey- 
yellow: anterior thighs yellow at tip: tibia yellow; posterior 
pair black, yellow at base. 

Length three-twentieths of an inch.

2. O. 4-noratus nob. Long’s Expedition. 

The male is almost destitute of spots on the second segment of 
the tergum, and all the tibiz have a white line. 

This species resembles the O. trispinosus Fabr., but that insect 
may be distinguished by the dilated figure of the spot on the basal 
segment of the tergum and by the tibizw being entirely honey- 
yellow. 

3. O. LaTus.—Line on the collar, on the scuteland five lateral 
spots on the tergum yellow. 

Inhabits Indiana. 

% Body black, punctured; head with a slight silvery reflee- 
tion: antenne ferruginous: mandibles yellow, piceous [876] at 
tip: collar with a transverse, somewhat undulated yellow line, 
interrupted in the middle : scutel with a double, transverse, yel- 
low spot ; metathorax with the middle spine simple; the lateral 
ones depressed, whitish, margined on the inner side with bright 
yellow : tergum with five yellow spots on each side: knees, tarsi _ 
and tibie yellow, the latter with a dilated black line on the inner 
side. 

Length nearly one-fifth of an inch. 

Smaller than mucronatus F., which is destitute of the scutellar 
line. It may be distinguished from the preceding species, by the 
yellow color on the collar and scutel. 


CRABRO Fabr. 


(©. CONFLUENTUS [CONFLUENS ].—Black, with large confluent 
punctures ; tergum interruptedly fasciate. 

Inhabits Indiana. 

Q Body black, densely and confluently punctured, particularly 
on the stethidium, where they are sometimes longitudinally con- 
fluent, so as to exhibit lines between them; they are largest on 
the metathorax ; hypostoma and anterior orbits behind the basal 
joint of the antennez, silvery : antenne, basal joint yellow; sec- 
ond joint honey-yellow ; collar yellow, slightly interrupted in the 
middle: scutel with a large, transverse, yellow spot; a yellow 
transverse line behind it; wings slightly tinged with dusky : 
abdomen oval, rather abruptly narrowed at base: tergum with 
the incisures contracted, the segments being conyex; approxi-

mately punctured ; segments on their middles, each with an equal 
band which is interrupted for only a narrow space at the middle : 
pleura with a yellow spot at the humerus: knees, tibia and tarsi 
yellow: venter immaculate. [377] 

Length over three-tenths of an inch. 

% Spot of the scutel interrupted or wanting ; antennz beneath, 
dull honey-yellow; the two posterior bands of the tergum gene- 
rally confluent in their middles; abdomen longer and more slen- 
der than that of the female. 

Length three-tenths of an inch. 

The sexes are more readily distinguished by the tip of their 
abdomen than by the antenne. I have nine males and three fe- 
males: two of the latter measure two-fifths of an inch. The 
punctures of this species are larger and more dense than in our 
other species. 


C. ancuatus.—Metathorax with numerous parallel lines ; ter- 
gum with yellow spots and bands. 

Inhabits Indiana. 

Body black, with minute, dense punctures: front with a wide 
glabrous interval between the silvery orbits: antennz, basal joint 
yellow, with a black line near the inner base ; sixth joint arcua- 
ted, a little prominent inwardly at tip: hypostoma yellowish-sil- 
very: thorax with a slightly interrupted line on the collar, of a 
bright yellow; a yellow transverse line beneath the scutel : wings 
a little tinged with dusky: metathorax with numerous, small, 
parallel lines, arcuated at base, and transversely rectilinear be- 
hind, extending upon the pleura beneath the wings: pleura with 
two small yellow spots before: tergum with an oblique some- 
what arcuated, yellow spot each side of the first segment; an 
oblique elliptic one on the second segment each side ; a reclivate, 
transverse, lateral yellow line on the third; remaining segments 
each with an entire, slightly undulated, slender greenish-yellow 
band: anal processes acute, very deeply and regularly ciliated : 
feet yellow: coxe and trochanters black: thighs at the base 
black ; the black portion very small on the anterior [378] pair, 
but on the posterior pair extending on the inferior surface to 
the tip: venter immaculate. 

Length two-fifths of an inch.

STIGMUS Jur. Latr. 


1. S. PARALLELUS.—This species resembles the fraternus nob. 
but it may be distinguished by the following comparative char- 
acters. The posterior thighs and middle of the tibiz are black. 
The stigma is a little smaller. The dividing nervure of the first 
and second cubital cellules is parallel to the posterior nervure of 
the second discoidal cellule ; whereas in the fraternus, the latter 
is more oblique. 

The size is much the same. 

Inhabits Mexico. 

The Stigmus fraternus, is not uncommon in Indiana, and as in 
the present species, the hypostoma of the male is somewhat sil- 
very. 

2..S. pusi~Lus.—Petiole obsolete: second cubital cellule 
large. 

Inhabits Indiana. 

Body black, polished: head before, and mouth, including the 
mandibles, whitish: antenne honey-yellow; basal joint before, 
whitish : wings hyaline; nervures pale brownish ; stigma fus- 
cous; second cubital cellule large, somewhat longer than broad : 
feet honey yellow; posterior pair blackish ; abdomen with a very 
short petiole, almost sessile. 

Length about one-twelfth of an inch. 

This is much the smallest species I have seen. The dividing 
nervure of the first and second cubital cellules is exactly opposite 
to the posterior nervure of the middle discoidal cellule. The 
hypostoma of the female is black. [379]

1. P. MARGINATUS.—Black ; antennze at base, mandibles and 
feet honey-yellow. 

Inhabits Pennsylvania. 

Body polished; antenne blackish; first and second joints 
honey-yellow; the former as long as the second and third to- 
gether, which are nearly equal: mandibles honey-yellow, not 
very obviously denticulated at tip: wings tinted with fuliginous; 
nervures brown; stigma fuscous, not much dilated; nervures of

the second cubital cellule and second recurrent nervure margined 
with whitish, the latter abbreviated before the anal tip: abdomen 
subsessile ; with the exception of the first segment, piceous 
blackish : “feet honey-yellow. 

Length over three-twentieths of an inch. 

The second cubital cellule is somewhat larger than usual, and 
the nervures which form it, as well as the second recurrent ner- 
vure, are less distinct than usual. 

2. P. annuLATUS.—Black; mandibles white; feet yellowish. 

Inhabits Indiana.

spot before the wings each side: wings very slightly tinted with 
dusky, more particularly in an obsolete band toward the tip: ner- 
vures fuscous: stigma brown: recurrent nervures entering the 
petiolated, cellule exactly opposite to its bounding nervures: 
spines very short: feet honey-yellow: tergum polished, first

2. A. MELLEUS.— Honey-yellow; head, pectus, and tip of 
the abdomen black. 

Tnhabits Indiana. 

Thorax honey-yellow: head black : mouth, anterior [381] orbits 
and basal joint of the antennz excepting a line on the exterior side, 
whitish: region of the scutel dusky: wings with a dusky band: 
metathorax honey-yellow, with the elevated lines rather slender ; 
the lateral lines of the dorsal area arcuated : tergum with the first 
and second segments honey-yellow, the latter with a lateral 
whitish spot ; remaining segments blackish; anal segment ob- 
scure piceous: pectus black: feet, excepting the base of the 
posterior coxze, honey-yellow. 

Length under one-fourth of an inch. 

The prevailing honey-yellowish color distinguishes this spe- 
cies ; and the metathoracic lineations are much finer than those 
of the preceding species. The lateral lines of the dorsal area of 
the metathorax in the oppositus are nearly rectilinear.

inner side and tip of the exterior side black : tarsi, anterior pair 
dull yellowish ; posterior pairs, except at base, blackish : venter 
immaculate.

Resembles C. deserta nob., but aside from other differences it 
may be distinguished by that species having somewhat clearer 
wings, and the inosculation of the first recurrent nervure being 
opposite to the middle of the second, or petiolated cubital cel- 
lule; the antenne also in that species are yellowish before, 
towards the base ; the scutel has two spots in addition to the 
yellow line behind it, and the bands of the tergum are always 
broader than in the present species. The fallax nob. differs in 
having the transverse yellow line on the scutel in a direct line 
between the origin of the posterior wings; whereas in the pre- 
sent species it is behind the scutel. 

2. C. sexTA.—A broad band on each segment of the tergum ; 
metathorax with a lateral spot. 

Inhabits Missouri. 

Body black; head before, base of the mandibles and basal 
joint of the antenne beneath, yellow; third joint of the antennz 
dull honey-yellow : collar with two large yellow spots: wing- 
seale and transverse line behind the scutel yellow; the triangular 
impunctured space behind the transverse line very obvious, with 
oblique lines and a longitudinal one in the middle: wings a little 
fuliginous particularly on the margin and tip; nervures brown ; 
stigma yellow ; recurrent nervure of the second cubital cellule 
entering at its middle : metathorax with a large, oval, longitudi-

This is much like the quadridens Linn., which is a true Ody- 
nerus, but it is destitute of the metathoracic spines of that spe- 
cies, and besides other differences it has a band on the second 
abdominal segment. This latter character not being very obvi- 
ous may readily have been overlooked by Fabricius. 

The male differs but little from the female ; my specimens 
have two additional white spots on the anterior portion of the 
nasus. .

low, emarginate at tip: mandibles yellow, honey-yellow at tip: 
antenne, basal joint yellow, with a black line above: front with 
a yellow line from the base of the antennge, into the emargina- 
tion of the eye, and a small spot above the interval of the an- 
tenn, yellow ; thorax, a bilobed spot on the anterior margin, 
wing-scale and small spot beneath it, and transverse spot behind 
the scutel, yellow: wings dusky: tergum not so grossly punc- 
tured as the thorax ; first segment with a yellow posterior mar- 
gin; second with a yellow small dot each side, and yellow poste- 
rior margin extending around the venter; remaining segments 
obsoletely margined at tip with yellowish: feet yellow; thighs 
black at base. 

Length over three-tenths of an inch. 

Like the acutus Latr., but may be distinguished by its more 
gross puncturing, as well as by the yellow dots on the tergum. 

A variety from Missouri, has the feet all yellow.

Resembles the annularis Fabr., but the ferruginous color is 
more prevalent; the hypostoma is not sericeous, a little more 
prominent in the middle; the basal abdominal segment is some- 
what larger and destitute of the annulation. JI have obtained it 
abundantly in Indiana and Mr. Barabino sent it to me from New 
Orleans.

Body blackish, sericeous, with a slight golden reflection : ely- 
peus not acute, but almost rounded at tip: mandibles at tip pi- 
ceous ; thorax with a distinct, longitudinal, impressed line be- 
fore, extending to the middle: wings yellowish; dusky at tip :

Not being able to find my notes relative to this species, I can 
only state, that near Jalapa, my attention was attracted by a 
group of Indians, who were eating honey from a paper nest, 
which was then so far dissected in their repast, that I could not

770 BOSTON JOURNAL 


ascertain its proper form. The honey had a pleasant taste, and 
as far as I could gather from their gestures, the nest was obtained 
from a tree. Some of the specimens above described I found 
crawling feebly away, and others I extracted frem the cells in a 
perfect state. 

The trophi agree with those of the P. nigripennis Oliv., except- 
ing that the obliquely truncated portion of the mandibles is a lit- 
tle longer, and the terminal joint of the labial palpi is equal to 
the preceding joint. 

I had made the above description and remarks before an op- 
portunity offered to compare the individuals with Latreille’s de- 
scription of his P. lecheguana (Ann. des [391] Sc. Nat. tom. 4, 
p- 835,) which I find it closely resembles, and to which I should 
refer it, but for the character attributed to that insect of having 
only the “bord posterieur des cing premiers anneaux de l’abdo- 
men jaune,” whilst all the segments of the tergum of our species 
are margined with yellow, and the anal segment is also of that 
color, in all the specimens which I have seen; all the segments 
of the venter, moreover, are margined with the same color ex- 
cepting the basal one. These differences induce me not to with- 
hold this description, as we may reasonably infer that others 
exist, which can be detected only by comparison. Whether this 
species is the artificer of either of the nests figured by Hernan- 
dez and copied by Latreille in Humboldt’s Zoology, I cannot 
determine, but it seems highly probable. The observation of La- 
treille relative to the insects that construct those nests, (or at 
least one of them, for they are very unlike each other) seems ju- 
dicious, that “ j’ai lieu de soupgonner que ces insectes sont iden- 
tique ou peu differens,” from his P. lecheguana. !

Length less than one-fourth of an inch. 

A very common species. I have found their nests in [896] 
the soft, decomposing sap-wood of the Oak and Hickory, between 
the bark and the solid wood. Their cells are oval, horizontal, 
not symmetrically disposed, though many are parallel. These 
cells are composed of particles of the decayed wood, agglutinated 
together. Each cell contains an individual, subsisting on a yel- 
low pollen, enclosed with it by the parent. In the same assem- 
blage are the young of all ages to the perfect insect. 

The male varies in having the tibiz and tarsi yellowish-white, 
with more or less of green on the middle of the posterior tibiz. 

The preceding species, distinguished by their polished green 
color, are also remarkable by the very obtuse emargination of 
their eyes, or, in other words, the curvature of the inner side of 
the eye: they might very properly constitute a division of the 
genus. 

5. H. nraarus.—Black; tergum banded with whitish.

current nervure entering the second cubital cellule near, but not 
at the dividing nervure : metathorax at base having the depressed 
surface granulated or very minutely lineated; posterior face sub- 
orbicular, slightly concave : tergum haying the posterior margins 
of the segments white with prostrate hair, beneath which the 
surface is piceous: venter a little hairy; posterior margins of 
the segments obscurely piceous: feet tinged with piceous, paler 
towards their tips; the posterior with pale ferruginous hair.

A common species ; at first sight somewhat like obliqua nob. 
which however is much larger, the bands of the tergum much 
narrower and more oblique than in the present species. In 
magnitude this species does not seem to differ widely from that 
which Drury names annularis ii. pl. 387, f. 7. That figure is, 
however, a very uncertain one, even as respects its genus, and in 
my copy of the work, does not at all agree with the description 
which accompanies it.

A smaller species than pruinosa and much like it; but it may 
be distinguished by the much longer antenne of the male, by 
the nasus being all white, and by the whitish or almost uncolored

Mr. Barabino sent me this species. It differs in many respects 
from the M. /atimanus nob. (Western Quarterly Reporter) which 
has in that species the anterior coxz black; the appendage of 
the anterior tarsi shorter, &c., but it is perfectly congenerie with 
it, as well as with Anthophora lagopoda Fabr., if I may judge 
by the similarity of the anterior feet, though it certainly ap- 
proaches S¢eles in the paucity of ventral hair. The maxillary 
palpi of /attémanus have the second joint rather longer than the 
first.

prolonged almost to the tip of the third joint; fourth joint not 
dilated : anterior tibiz with dilated crowded punctures : anterior 
cox, each with a prominent, black spine: intermediate and 
posterior tarsi piceous at tip. 


1837.] 


784 BOSTON JOURNAL 


Length over two-fifths to nearly half an inch. 

Y Frontal hair shorter and less conspicuous; anterior feet 
simple ; venter with dense yellow hair. 

Length over half an inch. [409] 

It is smaller, much more slender and much less hairy than 
either latimanus, or pollicaris nob., and has a somewhat different 
habit. 


ANTHOPHORA Latr. 


1. A. AsrupTA.—% Black ; thorax with cinereous hair; nasus 
and labrum whitish. 

Inhabits Indiana. 

Body robust : antenng on the anterior side of the basal joint, 
whitish : nasus, and each side of it to the eye yellowish, a little 
tinged with fulvous in the middle: labrum pale yellowish, hairy : 
mandibles having a whitish spot near their outer base: thorax, 
pleura and pectus, clothed with whitish cinereous hair: wings 
hyaline ; nervures ‘fuscous; stigma not at all dilated: pleura 
with an oblique line of black hairs passing downward and back- 
ward from the posterior wings: tergum with much shorter and 
less dense hair than that of the thorax, and black; that of the 
basal segment a little longer, and near the metathorax partaking 
of the color of the hair of that part: feet black ; the longer hairs 
of the anterior pair are whitish. 

Length over half an inch. 

It is less robust than A. pilipes F. and is equally well clothed 
with hair on the anterior part of the body, but the transition of 
color between the hair of the thorax and that of the tergum is 
much more abrupt. It has much the appearance of a small hum- 
ble-bee and also resembles Andrena thoracica F. 

2. A. rronTATA.—Thorax with yellowish hair; hypostoma 
and basal joint of the antenne beneath, and spot at base and 
near the tip of the mandibles, yellow. 

Inhabits Louisiana. [410] 

% Body black: hypostoma yellow and with yellow hair: an- 
tennee with the inferior longitudinal half of the basal joint yel- 
low, and with dense yellow hair : nasus yellow, with yellow hair: 
labrum black, covered by the hair of the nasus: mandibles with 

[Vol. I. 


OF NATURAL HISTORY. 785 


a yellow oval spot at base anda slender obsolete one near the 
tip: maxilla with an obsolete yellowish spot before the palpi : 
palpi with a few rigid hairs; terminal joint one-third the length 
of the preceding joint : tongue ferruginous : vertex in the middle, 
having a few yellow hairs : thorax with dense, long, yellow hair : 
wing-seale blackish: wings with a slight dusky tint; nervures 
black, exterior recurrent nervure entering the outer cubital 
eellule directly opposite to the outer nervure of the cellule : ter- 
gum hairy; hairs black, rather long; a few yellow hairs towards 
the middle of the first segment : anterior feet with yellow hair on 
the posterior edge: hind feet, hairs not much elongated. 

Length half an inch. 

Sent to me by Mr. Barabino. Differs from the abrupta nob., in 
being less robust, the hair of the thorax being pale yellow, and 
the mandibles having a white spot near their tips. 

3. A. TAUREA.—Thorax pale, with a dusky central spot, from 
which proceed two lines to the anterior angles. 

Inhabits Indiana. 

Body black with whitish cinereous hair: head, hair on the 
vertex dusky: thorax with whitish hair; a large, obvious, cen- 
tral, dusky spot, with a line curving from it to each anterior 
angle of the thorax: scutel, hair dusky: metathorax and first 
segment of the tergum, with cinereous hair; remaining segments 
of the tergum with the hair very short and black, excepting on 
the posterior margins which are pure white: ? ultimate segment 
with [411] a glabrous, subcarinate, triangular, oblong space 
above : wings hyaline; nervures fuscous ; stigma not suddenly 
dilated: terminal third of the radial cellule slightly separated 
from the edge of the wing; terminal nervure of the third 
cubital cellule inserted at the middle of the nervure of the radial 
cellule. 

Length g about two-fifths; ? half of an inch. 

The thoracic spot will readily distinguish this species. The 
manners and habits of the species may be likened to those of the 
A. parietina Latr. It digs a eylindrical hole in compact clay or 
adhesive earth on the side of a bank, orin earth retained amongst 
the roots of an overturned tree. The hole is two or three inches 
in depth. The sides and bottom are of a dark brown color, quite 


1837.] 50 


786 BOSTON JOURNAL 


smooth and somewhat polished, containing a quantity of white 
pollen, considerably larger than the artificer itself. The entrance 
consists of a cylinder extending downwards from the mouth of 
the hole, more than an inch in length, and consisting of small 
pellets of earth compacted together, very rough on the exterior 
and smooth within. A species of Odynerus was numerous in 
the same locality in which I observed the above, and sometimes 
entered the holes ; but the exterior cylinder does not agree with 
that which is attributed to O. muraria Latr. which Kirby and 
Spence inform us is composed of “ little masses so attached to 
each other, as to leave numerous vacuities between them, which 
give it the appearance of filagree-work.” Many of the tubes of 
the taurea, have a fissure above, throughout the whole length ; 
resembling in this respect the shell Stliguaria. It does not 
agree with Fabricius’ description of Melecta remigata. [412] 


XYLOCOPA Latr. 


X. cARoLINA Fabr.—This species was referred by Fabricius 
to the genus Centris, and is even now generally considered as be- 
longing to that genus. But doubting the accuracy of that 
arrangement, I found on examination, that the labial palpi are 
rectilinear, the terminal joints being in a right line with the 
others, and the maxillary palpi are six-jointed. The} mandibles 
have only one large tooth, which is on the inner side. The cir- 
cumstance of Fabricius referring to Drury’s fig. 1, pl. 43, of vol.i, 
for Bombus virgineus Linn., leads me to suppose that he had 
this species also in view in that description. Butas that deserip- 
tion in the Syst. Piez. p. 346, agrees very well with one of our 
largest and finest species of Bombus, rather than introduce a 
new name, I would transfer the quotation of Drury’s figure to 
the description of Y. carolina, (Centris), F. I add the follow- 
ing description of it, which I formerly drew out, with the name > 
of valida, under the belief that the carolina, is really a Centris, 
and therefore altogether different. 

Blackish ; a prominent, compressed, obtuse tubercle between 
the antenne; thorax hairy. 

Inhabits United States. 


9 Body black, tinged with purplish: head with close set, 
[Vol. I. 


OF NATURAL HISTORY. 787 


discoidal punctures; an obvious, compressed tubercle between 
the antennz, rounded at its tip: labrum conic: thorax tinged 
with greenish ; with pale yellow hair, except on the saddle : 
wings fuliginous, subopake at tip: tergum tinted with very ob- 
scure green: basal joint covered with pale yellow hairs: pleura 
beneath the wing, with yellow hairs. 

Length about four-fifths of an inch. [413] 

% Nasus white. The tubercle of the head is very distinct. 

Common in the Union. The males may be distinguished by 
their larger and more approximate eyes and white nasus. It 
varies in having the hair of the thorax and of the first abdominal 
segment, almost ferruginous. 

2. X. LATERALIS.—Violaceous; abdomen with a posterior 
lateral cinereous spot. 

Inhabits Mexico. 

% Body blackish-violaceous: head black: nasus and labrum 
white : antennze with an anterior white line on the radical joint : 
gene with a few gray hairs : wings, first recurrent neryure enter- 
ing the third cellule within the distance of its own breadth from 
the nervure of intersection of the third cellule: abdomen, each 
side near the tip with a cinereous spot of hair, extending up- 
wards on each side of the venter, but becoming obsolete towards 
the base. 

Length over seven-tenths of an inch. 


BOMBUS Latr. 


1. B. sonorus.—Yellow; head, thoracic band and abdomen 
behind black. 

Inhabits Mexico. 

Body yellow: head black: thorax with a broad black band in 
the middle: wings violaceous-black: tergum with the first, 
second and third segments yellow, the others black: beneath 
black. 

Length 9 four-fifths of an inch. 

Resembles the fervidus Fabr. so closely that it may readily be 
mistaken for it, but that species has only two segments of the 
tergum clothed with yellow hair; that of [414] the second one, 
however, is so much elongated as to conceal a considerable por- 


1887.] 


788 BOSTON JOURNAL 


tion of the next segment. The color is a much deeper yellow 
than that of fervida. 

2. B. EPHIPPIATUS.—Black ; pleura and base of the tergum 
yellowish. 

Inhabits Mexico. 

Body black: pleura pale yellow: wings dusky, tinged with 
violaceous: tergum pale yellow towards the base ; this color is 
gradually narrowed behind and terminates on the third segment, 
forming somewhat of a semioval, with its base to the thorax and 
confluent with the color of the pleura. 

Length less than half an inch. 

3. B. TeRNARIUS.—Yellowish; thorax fasciate; tergum ful- 
yous in the middle. 

Inhabits Indiana. 

Head black: thorax with dull yellowish hair, and a blackish 
band on the middle: wings with a slight yellowish tinge; ner- 
vures fuscous : tergum fulvous on the second and third segments; 
first and fourth segments yellowish ; remaining segments black. 

Length % nearly three-fifths of an inch. 


TRIGONA Jurine, Latr. 


1. T. pringeata.— O Blackish ; antennze, beneath, labrum 
and two lines on the nasus pale. 

Inhabits Mexico. 

Body piceous black ; flagellum of the antennz beneath, obsolete 
narrow anterior orbits, two rather broad lines on the hypostoma, 
labrum and mandibles somewhat pale: wings hyaline, slightly 
tinged with fuliginous towards the base; cubital cellules obso- 
letely divided into three by two [415] hardly perceptible ner- 
vures ; ultimate cellules hardly attaining to the tip of the wing ; 
the second receiving the recurrent nervure: feet not different 
in color from the body; posterior tibie with the cilis of the 
edge sparse. 

Length less than one-fourth of an inch. 

It is somewhat smaller, and less robust than the ruficrus Latr. 
of which the posterior tibize are densely ciliated. I am indebted 
to Dr. Klug for a specimen of the rujficrus: and it is very differ- 


ent from the amalthea and spinipes Fabr. My specimens are 
[ Vol. I. 


OF NATURAL HISTORY. 789 


workers, and I did not find the nest or ascertain the kind and 
importance of the honey they make. The generic name is almost 


too much like Trigonia of Conchology, but as the pronunciation 
differs it can remain. 


2. T. tigata.— © Blackish ; abdominal segments margined 
with ochreous. 

Inhabits Mexico. 

Body brownish-black, hairy; antenne beneath, particularly 
the basal joint, anterior half of the anterior orbits, line distin- 
guishing two lobes of the hypostoma and mouth, dull yellowish : 
wings slightly tinged with fuliginous, particularly towards the 
base ; nervures of the cubital cellules like those of the bilineata 
nob., but the first one is much more distinct: tergum shortly 
hairy; posterior margins of the segments ochreous: feet dull 


honey-yellow ; tip of the posterior tibize and base of the first tar- 
sal joint black. 


Length about two fifths of an inch. 

Of this I obtained but a single specimen, which is a worker. 
It is widely different from the preceding species, particularly in 
being hairy, and is much larger and of a somewhat different 
habit. I have carefully compared it with Latreille’s descriptions 
and figures of Melipona [416] favosa Illig., scutellaris Latr., fas- 
ciata Latr., interrupta, Latr., and other species as given in Hum- 
boldt’s Zoological Observations ; and even should it be referred 
to that genus notwithstanding its denticulated mandibles, I have 
endeavored to draw out such characters as may distinguish it 
from them. Latreille, however, says of Melipona, “ Mandibles 
sans dentelures apparentes ” which entirely includes this species, 
although it agrees in habit.
