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. &c.

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.

XVIII: ante, 1, 35.]

2. C. DEcEMNOTATA, American Entomology, Plate VI. [Plate
AVI: 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 punc-
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-

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. ©. HIRTICOLLIS.—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
divaricated 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 CO. 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. ©. pusttuA.—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 lunule 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 ofan inch. Found by Mr. Nuttall. The
band is often obsolete, or only detached portions of it are visible,
the enlarged marginal part is permanent. [22]

OF PHILADELPHIA. 3

Genus NEMOGNATHA Illiger, Zonitis of Fabr. and Latr.

Maxillee very much elongated, inflected, filiform.

N. IMMACULATA.—Lemon yellow, immaculate. Hlytra with
scattered punctures. Maxilla not longer than the thorax, and with

the antennz and palpi black.

N. immacunata, 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. Llytra 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 N. vittata.

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

Genus ZONITIS Fabricius and Latreille.

Maxille not elongated. Antenne 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. LElytra pale yellowish, with a
black fillet. Scutel black.

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

Antenne 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

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.

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 Fabry. Tri-
chocera of Lamarck. Cecidomyia of Latr. and Meigen. '

Antenne filiform, joints subequal, globular, hairy. Proboscis
salient. Wings incumbent, horizontal.

C. pestRucTOR.—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 fulyous at base, furnished at the tip with

[Vol. I.

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

Female.—Antennx 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 crenulze ; 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. 2382, and
named by him Zipula Tritic?, is without doubt of the same ee
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 oe 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
eges 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. prstrucToR.—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.

[Vol. I.

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 Ichneumon 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,” Xc., 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. CEPHALOSTOMATA.
Order Ist, PODOSOMATA.

Genus *ANAPHTA.+
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 :
coxe 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 ;)
coxe second joint clavate ; tibie first joint 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 Phoxichilus 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 ean discover,
he has omitted in his subsequent works. It will of course be a
second species of this new genus. _

Order IT. POLYMEROSOMATA.

Family 2. SCORPIONIDE..
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.

[ Vol. aE.

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
scabrous 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 Kast 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 Linneé, 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.

1. C. muricatus.—Third joint of the palpi nearly three times
1821.]

12 ACADEMY OF NATURAL SCIENCES

as long as the second, linear, gradually a little attenuated to the
base ; thorax muricated.

Inhabits North America.

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,
&c. Ifound a variety on the river St. John, in Hast 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. CO. 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-

OF PHILADELPHIA. Is

siderable resemblance, in the form of the palpi, to the C. Geoffroyt
of Leach, (Zool. Mise. 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;
mandibles salient much shorter than the body: eyes two, sup-
ported on a common tubercle.

1. P. virratum.—Whitish, with a dorsal fuscous vitta ; termi-
nal joint of the palpi not pectinated with spines.

Tnhabits the Southern States.

Cabinet of the Academy.

Body whitish, truncated and fuscous behind, a dorsal fuscous
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-
terior one is semicircular including the ocular tubercle, the inter-
mediate one transverse, and the posterior one recurved; ocular
tubercle prominent, slightly contracted at base, crowned with from
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 coztu, but have considered them

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

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

Inhabits the United States.

habitant of the Northern States.

Family 3. ARANEIDEM.

Although I have a considerable number of descriptions of
Araneides, which I think are new, yet, as Iam 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.

narrowing behind, densely covered with short silken hair ; thorax
elongated, sublinear, slightly contracted before the middle, and
with a darker, central line above: eyes white, placed in a trans-
verse line ; feet paler, whitish.

of the palpi with five or six acute spines above.

Cabinet of the Academy.

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

2. G. SPINIPES.—Body suboval, hirsute, rufous; feet with
rather longer distant hairs, second pair very robust, third joint
armed beneath with a large, prominent, acute, spine, which is
nearly as long as the transverse diameter of the joint, compressed,

Cabinet of the Academy.

Body spheroidal, somewhat oval, glabrous, polished, black ;
head longitudinally semi-oval ; 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
over the mouth, and the whole of the thorax is then deflected
upon the anterior part of the body ; in this state the general form
is a solid oval.

half as long as the body, with two or three pairs of stouter
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,
the posterior ones rather longer. [75]

Length rather more than one-twentieth of an inch.

Found in Georgia, under stones, under bark of decaying trees,
&c., in rather moist situations.

Genus IXODES Latr.

Palpi short, simple, valvular, forming with the haustellum a
short rostrum; mandibles none; feet with a pedunculated pul-
villus and two nails; eyes obsolete or wanting.

with sanguineous, particularly behind, and with several longi-
tudinal and oblique, black, abbreviated lines, scattered pune-
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.

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.

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 Z lineatus, if so,
my name must of course be rejected.

6. I. PUNCTULATUS.—Body oblong-ovate, gradually attenuated

terminated by a moveable appendage: body subglobular; feet
natatory.

H. TRIANGULARIS.—Body white; eyes two, sanguineous ;
tergum with a black triangular spot near the eyes, posterior por-
tion black, with a white dorsal line terminating in the cloaca.

The specimen, from which this portion of a description was
taken, I found in Unio cariosus, in which, possibly, it had ad-
ventitiously effected a lodgement. [ 80]

Genus LIMNOCHARES Latr.

Rostrum hardly prominent; palpi incurved, simple ; mandibles
none; feet natatory.

L. EXTENDENS.—Body ovate, red, minutely lineated; tergum
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, Xc., in forests,
and shady places. The posterior feet being destitute of cilize,
are only useful in walking; when the animal is swimming, they
are extended behind, without distinct motion. The eggs are
elobular, 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,

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 specimen 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. L. uisprpus.—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.

I 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, &c.

Genus CRYPTOPS Leach.

Anterior edge of the labium not denticulated, hardly emar-
ginate ; eyes obsolete ; posterior pair of feet longest; basal joint
unarmed.

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

Inhabits Georgia and Kast Florida.

My Cabinet.

Head reddish-brown, polished, impunctured, with scattered
hairs, no impressed clypeal line ; antennz reddish-brown hirsute,
joints sessile, cylindric, terminal ones rounded: body white,
polished, two black internal lines, a few sparse hairs, impune-
tured; feet with a few hairs; posterior feet reddish-brown, first
joint not so long as double its breadth, and with the second joint
armed with numerous short, rigid sete, with an indented line
above; third joint four or five toothed within, fourth joint about
two toothed.

Length three-fifths of an inch.

Numerous spécimens 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.

On a South American species of @strus 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.

“ (sTRUS 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 (strus ; 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 (. 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.

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 Q’strus 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 Wstrus 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 Wstrus ; 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.
—L«c.] 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 [357] numerous minute tubercles of the same
character with the others, excepting that they conform to no regu-
lar series ; the anterior [posterior.—L«c.] 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.

Cabinet of the Academy.

Obs. From this description we may gather the facts, that the
larva in question corresponds with that of (M. 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 Linnzan Wstrus 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 a very 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

poderma for this genus.

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, I 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 having 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.

“In 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 [ 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.

[Vol. ID.

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 Wstri
in the human body, consult Keferstein, iiber Gstrus hominis
Verh. Zool. Botan. Vereins in Wien, 1856, 637.

While travelling in Honduras, several of my companions were
very much afflicted with similar larvee; they seem to infest par-
ticular portions of the body not usually exposed; the pectoral,
dorsal 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

note several species of Culex.—s.

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. ]

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 85° 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

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 Kastern 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

2. 0. 5-rascratus.—Body clothed with cinereous hair ; abdo-
men annulate with blackish.

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

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 vitta
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-

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

Tnhabits Pennsylvania.

Head above with rather long yellow-ferruginous hair ; antennz
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-
fatus Fabr., although we must infer from his description, that
the posterior tarsi [12] only are annulated. Wiedemann con-
siders the e/ngulatus 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.

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, &c., 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.

curved line to the origin of the wings; pleura with a silvery
line; wings hyaline, nervures brown; poisers yellowish-white ;
feet including the coxe white, tarsi dusky; abdomen elongated,
depressed ; tergum blackish-brown, darker towards the tip, first

The third nervure of the costal margin is much less distant
from the second, than the corresponding nervures of S. sabea
Meig., and the first basal cellule is much less elongated, and the
superior branch of the apical fork is much less arquated than in
that insect. .

[Wiedemann removes this species to Lomatia, adding at the
same time that it probably belongs to some other genus.

placed transversely, and one near the tip of the opaque portion ;
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 and occipital orbits wlth white hair: stethidium
with fulvous hair, particularly on the sides of the thorax, on the
pleura and collar; wings as far as the basal transverse nervure
fuscous, costal nervures fuscous, the included areola yellowish-
brown, feet, the hair with a whitish reflexion; tergum with a
band of prostrate yellowish hair at the base of each segment, and
with long fulvous hair each side as far as the middle of the
length.

Length nearly one-fourth of an inch.

It belongs to Wiedemann’s fifth tribe.

with four series of silvery points.

Inhabits Pennsylvania.

Head reddish-brown, obscure covered by yellow ferruginous
hair, intermixed with longer black hairs, a black band on the
hypostoma, a black spot on each frontal orbit, and vertex black ;
thorax dusky, or blackish, with three black vitte, 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.

black at base.

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

Found in Pennsylvania, and also in Missouri. It belongs to
Wiedemann’s fifth tribe.

6. A. trRoRATUS.—Black; wings hyaline, with numerous
black punctures.

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. 28. 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.

This insect closely resembles the preceding species, [74] but
the elongated first joint of the antennze, 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 nervures is pre-
cisely as in L. ephippium.

[Wiedemann who had specimens communicated by Say before
him, describes this species as Dilophus orbatus Say. I collected
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 nervure distinctly, others have it very faint, and others
again show a beginning of it. This cross nervure, 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.

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 Dilophus, (D. serraticollis Walker ?), which
is, besides, a little smaller. The females of the two species are
entirely different, and cannot be easily mistaken.—SAcKEN. ]

It requires some examination to perceive the difference be-
tween this insect and the S. corollz 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.

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.

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 S., 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.

Size of WS. 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]

This appears to be a much smaller species than the Hippobosca
cervt of Oliv., to which it is very probably allied, though on cor-
parison with Oliver’s description I conclude it is very sufficiently
distinct. It has, like that insect, slight rudiments of wings.

B. CYANIPENNIS.—Testaceous; elytra blackish-blue ; venter
dark reddish-brown.
Length near seven-twentieths of an inch.

1823.]

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 with a
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 B. 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
fumans, 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.

FERONTA Latr.

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

Length nearly two-thirds of an inch.

Body black, impunctured, glabrous: antennz 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 ; strize profound, impunc-
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 sfygicus, but the thorax is differently formed, being
much wider before, the antenne longer, frontal grooves more
dilated, the elytra of a different color and more obtuse.

wards the tip with light brownish hair: palpi, tip of the mandi-
bles and of the labrum piceous, the former tipped with pale yel-

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 ; stria 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

before the eyes and on the orbits: antennz, palpi and suture of
the clypeus yellowish: thorax with a few punctures each side,
and an abbreviated oblique series of punctures each side before

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 oblongus, which, however, is said to haye
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.

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 [202] 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.

one transverse and profoundly emarginate; a longitudinal obso-
lete impressed line above; a transverse indented cavity or punc-
ture each side, beneath which is an oblique elevated line con-
fluent anteriorly with’ the edge of the thorax ; anterior angles
emarginate : elytra with profound, [205] indented, crenate, di-
lated strie ; interstitial spaces, punctured.

Length seven-twentieths of an inch.

This insect appears to be a general inhabitant of the United
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
of 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. CO. HISTEROIDES.—Dark cupreous ; clypeus emarginate; an-
tennee yellowish.

Inhabits the United States.

Scarbzus 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: antennx
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 cilz; exterior edge four-toothed, the
posterior tooth minute or obsolete ; termina] spine acute.

Length more than one-fourth of an inch.

This insect, which occurs in Pennsylvania, I 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 having 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. OBSOLETUS.—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: antenne 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 striz: 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.

SCARABAUS 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. III.

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.

Scarabzeus 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
clypeus, 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

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-
burnii 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 striz.

Scarab. strigatus Knoch in Melsh. Catal.

Body deep black, immaculate: clypeus with very minute punc-

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,
striae 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.

Scarabeus 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.

rounded: scutel blackish: elytra rufous, immaculate, striate, the
stri 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. conCcAVUS.—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, stria 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 thoracie punctures in one specimen are obsolete. [215]

verse impressed line between the eyes, which is angulated in the
middle: thorax punctured: elytra with punctured strie, and
very minute punctures in the interstitial spaces.

Length three-tenths of an inch.

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.

it disagrees with the descriptions of each of these insects, by
having a very distinct and rather large scutel, inserted at the base

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

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 |

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 tristis 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 ¢ristis are said to be glabrous, and the scu-
tel white.

This insect is beautifully iridescent, and by this character is
readily distinguishable from all other North American insects of

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 M. 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.”

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 platycerus Melsh. Catal.
[Vol. III.

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
elevated 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.

Length 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.

mate one subacute at tip, precisely resembling the corresponding ~

_joimt of FLurychora 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 maxillz so much as
that of Pimelia bipunctata: thorax curvilinearly emarginated
before for the reception of the head; punctures very minute,

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.

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 antennz, a prominent acute angle: an-
tenn 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
acute 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-
fuent; those of the disk smaller and distinct; lateral edge ree-
tilinear: elytra with profound, excavated punctures at base, and
smailer 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.
flavicollis 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

the terminal joint smaller and shorter than the preceding, and
[Vol. Ii.

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. 8, No. 59, Pl. 1, and although this terminal joint is
proportionally larger than that of the bipunctata, yet it is not
more dilated than that of Yentyria glabra, which is admitted
into the same subdivision with Pimedlia.

The anterior tibiz 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.

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 |

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 Scauwrus
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 Blapsidz, under a separate genus, which may
be named Lmbaphion. — 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 beimg armed with a horny
nail, excludes it entirely and Sap ey from the family of which
Heleus is a member.

allied to Hleodes than to Akis—LEC. |

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, excurved near the base :

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 antennee
gradually become a little wider and shorter to the terminal one,
which is less than half the size of the preceding joint. The

mentum is much dilated and at tip emarginate, concealing the
inferior portion of the maxille, with the exception of a point

ceous, edged with black, excepting the exterior edge near the
base ; extreme tip and spot on the anterior part of the humeral

Length about a quarter of an inch.

This species resembles the male of dimidiatus Fab., and hume-
ratus Fab., but the vertex of those twe 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. Sayt,
(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 R. pectinatus Fabr.,
(varicolor Gersteker). Although Gerstecker has placed R.
bicolor Ol. as a synonym of P. 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 Gerstaec-
ker asa synonym of his R. 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.—Lxc.] [276 ]

Length more than two-fifths of an inch.

This species is an interesting addition to the catalogue of
North American insects, as it is the only one of its very limited
genus, yet found here: It must be rare, only a single specimen
having yet occurred. It is very distinct from the three or four
species already known.

MELOE Linn. Latr.

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

Inhabits Pennsylvania.

Body dark violaceous, punctured: head with profound pun-

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 M. 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

the insect are more violaceous. When taken, it diffused an odor
very similar to that of some Blattez.

2. M. conrerTa.—Black, with dense punctures; antenne
regular.

Inhabits Missouri and Arkansa.

Body black, opaque, punctured ; punctures’ crowded, concave,
equally distributed, confluent, furnishing short black hairs : head
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.

1. L. FERRUGINEA.—Black, covered with short ferruginous
hair.

Inhabits Missouri Territory.

Body above invested with crowded ferruginous, short, prostrate
hair; beneath darker in consequence of the more sparse hair:
eyes brown, oval: antenne hardly larger than the thorax, gla-
brous, black; basal joint hairy: labrum and palpi glabrous,

3. L. spHmRICOLLIS—[ Ante, 1, 7.] - [300]

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 Zonittis,
as defined by Latr., Régne Animal, and together with those of
the species aenea, polita, sphzericollis 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 Mylabris; 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 antennze 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.

Body above glabrous, punctured ; beneath hairy; head brassy,
polished, with distant punctures: eyes large, oval, entire, promi-
nent: antenne black, rather long; joints oblong-conic, terminal

ble a twelfth joint; tip acute: labrum blue, bilolate, lobes divari-
cating : palpi black, not remarkably dilated at tip: thorax gla-
brous, brassy, polished, punctured each side, distinctly wider be-
fore the middle: scutel hairy: elytra pale olivaceous, [303]
tinged with brassy, slightly rugose: two slightly elevated, obso-
lete lines: feet rufous, knees and two anterior pairs of tibia
blue: tarsi fuscous.

Length three-fifths of an inch.

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, &e.

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.

Body black, covered by very numerous, short, prostrate black
hairs: head with an obsolete, hardly perceptible, rufous, abbre-
viated, frontal line ; anterior edge of the clypeus somewhat pale ;
beneath, and each side before the eyes, covered with cinereous
hair; antenne, second joint. two-thirds the length of the third

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 D. ferruginea, but that
insect is very different in the proportional length of the an-
tennee. [ 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
Horta in the form of the tarsi, which are bifid and pectinated,
in this respect widely differing from Lytta, &c., of which the
tarsi are simply bifid.

This species exhibits the general form of brevicornis, but the
the thorax is proportionally much narrowed, and the characters

3. P. PALPARIS.—Black ; thorax tridentate ; terminal joint of
the maxillary palpi longer than the preceding one. [ 328 ]

Inhabits the upper part of the Arkansa river.

Body black, immaculate, punctured; head confluently punc-
tured ; an impressed, longitudinal line: maxillary palpi with the
last joint longer than the penultimate one: thorax, punctures
rather more sparse on the disk; lateral margin not dilated ; edge
tridentate ; anterior tooth a slight prominence of the anterior
angle ; intermediate one acute, subconic, spiniform, not reflected ;
posterior tooth not prominent, and consisting only of the poste-
rior angle: elytra slightly punctured, nearly smooth; tip slightly
mucronate : pectus and postpectus of the male hairy; hair yel-
lowish.

Length, male one and one-fifth, female one and a half inches
nearly.

I observed several specimens of this species on the Arkansa
near the Mountains. It resembles at first sight P. brevicornis
Fab., but it differs from that insect in some important characters,
the elytra are much smoother, the thorax is not so broadly mar-
gined on each side, the intermediate thoracic tooth is more spini-
form ; but the most characteristic difference appears to reside in
the maxillary palpi the terminal joint of which is very conspicu-

dentated with very small, obtuse teeth; an obtuse angle behind
the middle: elytra punctured, destitute of elevated lines: post-
pectus with short yellowish hair: tibia densely ciliated with yel-
lowish hair on the inferior edge.

Length one inch and three-fifths.

The specimen, from which this description is taken, is a female ;
in general form it approaches P. cylindricus, but the thorax is
broader and destitute of spiniform teeth; the third joint of the
antenne is obviously shorter than the first, and the tibiee 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.

Body glabrous, black : antennz shorter than the body, obso-

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.

Tnhabits the United States.

Body blackish-brown, with sparse, cinereous, prostrate hair,

antennze longer than the body, attenuated: thorax cylindric,
rather long, narrower than the elytra; with four ferruginous

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

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

The entire termination of the elytra sufficiently distinguishes
this species from the oculaticollis, and it is also a more robust

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 Oliv., as the antennee of that insect are de-
scribed to be as long again as the body.

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

5. S. pERGRATA.—Black, covered with cinereous hair; an-
tennee 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]

7. S. BrvitTaTA.—Hoary ; above light brown, with two broad
white fillets.

Inhabits the United States.
[ Vol. III.

OF PHILADELPHIA. 191

Body white: eyes fuscous; a small spot on the vertex, and
another behind each eye, light brown: antennz moderate,
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.—LeEc.]

8. S. MuticA.—Reddish-brown, covered with cinereous and
ferruginous hair; elytra mutie; 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 : antenne 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.

nent line; punctured; punctures enclosed by minute, irregular,
indented lines: pectus, punctures very minute : venter, posterior
margins of the segments highly polished.

Length one inch and three-tenths.

Appears to be a rare insect. I found but one specimen on the
Arkansa river near the mountains. [411] The elytra to the

This species very much resembles C. discoideum, but is much
smaller; and besides other differences, the punctuations of the
head and thorax are very distinct both in point of form and posi-
tion, being crowded and rounded in discotdewm, and comparatively
distant in the present species.

194 ACADEMY OF NATURAL SCIENCES

Length one-fourth of an inch.

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-
yania. The name bicolor is preoccupied by an insect of South
America.

6. C. BREVILINEUM.—Black ; thorax bituberculate ; elytra vio-
laceous, with three abbreviated, white lines.

Inhabits the United Sates.

Body black, scabrous, with small, elevated points: head with

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 seven-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.

Inhabits Arkanga.

Body deep black, covered with dense black hair: antenne
rather longer than the body, somewhat hairy: palpi glabrous,
deep reddish-brown: thorax, above with four obsolete tubercles,

slightly prominent, lateral spine: scutel hairy, black: elytra yel-
lowish-fulvous, covered with dense, very short, prostrate hair ;
four longitudinal, slightly elevated lines.

vitta on each.

Inhabits Missouri.

Head black, with much crowded punctures ; an impressed line
between the antenne: antenne as long as the body: thorax
slightly punctured ; two longitudinal black spots, and an anterior
posterior submarginal, impressed line, and an obsolete, dorsal,

longitudinal one; an obtuse, slightly elevated, lateral tubercle :

196 ACADEMY OF NATURAL SCIENCES

scutel black : elytra densely punctured, rounded at tip, with two
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.

[Unknown to me.—LEc. ]

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

Inhabits the United States.

Rhagium sericeum 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 elevated 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 Rhagiwm, and has been
referred to that genus by Mr. Melsheimer in his Catalogue ;
but as the thorax is destitute of armature, and the antenne are
longer than the body, I prefer giving it a place in the present
genus, agreeably to the generic characters of Latrcille and Leach.
I think it ought [418] to form a distinct genus, together with
Rhagium trivittatum.

[Vol. LIL.

OF PHILADELPHIA. 197

It is rather rare. The trivial name, applied by Mr. Knoch, is
pre-occupied in this genus.

3. L. Bicotor.—Rufous, sericeous ; elytra black.

Inhabits the United States.

Leptura bicolor Melsh. Catal.

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.

4. L. ruBricA.—Black ; elytra and abdomen rufous.

Inhabits the United States.

Leptura rubrica Knoch in Melsh. Catal.

Body black, punctured, with numerous short hairs above, and
scriceous beneath: head obsoletely punctured: antenne as long
as the body ; [419] six terminal joints fulyous at base: thorax
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.

Length about half an inch.

This insect occurs on the Missouri. It is found in Pennsyl-
vania, but I have not frequently observed it.

5. L. 8-Notara.—Black, hairy ; elytra each four-spotted.

Inhabits Mississippi.

an impressed, longitudinal line: antenne not longer than the
body: thorax subcylindric: elytra polished; each elytron with
four subtriangular, equidistant, yellow spots; the basal one at
the base, and the terminal one near the tip; hair near the tip
shorter, and nearly prostrate ; tip truncate, mutic: posterior feet,
with the base and tarsi, yellowish.

Length less than half an inch.

But a single specimen of this species was taken by Mr. Nut-
tall on the Mississippi.

tata Hald.—Lkzc. ]

6. L. LUGUBRIS.—Black ; sericeous beneath; antenne shorter
than the body.

Inhabits Lower Missouri.

L. scutellum-album ? Knoch in Melsh. Catal. [420 |

Body deep black, immaculate, with short, prostrate hairs above,
and yellowish-sericeous ones beneath: head with an elevated line
between the antenne: antennz. rather shorter than the body:
thorax conical ; posterior margin grooved ; posterior angles acute:
scutel with yellow hair: elytra attenuated; tip obliquely truncate,
subemarginate; the external angle acute and prominent, the inner
one rounded.

Length rather more than two-fifths of an inch.

Two specimens of this species were taken by Mr. T. Nuttall
on the banks of the lower part of the Missouri.

7. L. proxima.—Black; elytra testaceous, with a black tip.

Inhabits Missouri.

Body deep black, hairy: antenne nearly as long as the body :
thorax rounded or suboyvate; 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 venter: tail entire.

Length less than three-fifths of an inch.

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

T 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.

[Vol. IL.

OF PHILADELPHIA. 199

The variety may prove to be a distinct species, bearing a similar
relation to proxima that the testacea of Linné does to the
tomentosa.

8. L. LinroLA.—Black ; elytra punctured ; suture, margin and
vitta, black.

Inhabits the United States.

Leptura lineola Knoch in Melsh. Catal.

truncato-emarginate : feet pale testaceous: tarsi blackish: abdo-
men dark reddish-brown, sericeous.

Length two-fifths to nine-twentieths of an inch.

This is an inhabitant of various parts of the United States. It
is found in Pennsylvania, and on the Mississippi, though I have
not observed it to be common any where.

9. L. RUFICOLLIS.—Black ; thorax rufous; labrum pale.

Inhabits Kentucky.

LL. collaris Melsh. Catal.

Body black, with very short hairs: antenne, basal joint dull
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 amore slender
form.

RHAGIUM Fabr.

1. R. rrivirrarumM.—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 colors on
its elytra, this species probably bears some resemblance to #. 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.

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

referred it, but for the small thoracic tubercles.

dibles black at tip: antennz 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 : scutel 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.

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 antennz
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

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. ©. punotipes.—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,

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

(Vol. III.

OF PHILADELPHIA. 219

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. 3-MACULATA.—Bluish-egreen ; elytra yellow, with a com-
mon band, and each with a triangular, black spot near the tip;
feet purplish.

Tnhabits the United States.

Chrysomela maculata Melsh. Catal.

3 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. coryi1.—Pale yellowish, testaceous; elytra bifasciate
with blue.

Inhabits the United States. Tlinois.

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

Body pale yellowish-testaceous: head with an impressed line
between the antennz: antennz 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 Adorium, 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) upon which it feeds.

[A species of Caelomera.—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:
antenne 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-

Inhabits Missisippi.

Body yellowish-brown: head with an impressed line on the
front : antennze and vertex black : thorax with a dorsal spot and
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.

[I have a species which agrees with this except that the elytra

rather behind the middle: elytra irregularly punctured; three
or four obsolete, elevated lines, of which the exterior one is
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 antennz 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
antenne 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-
lar to Criaceris vittata of Fab.

[Belongs to Phyllobrotica.—LE¢. ]

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-

cated ; tergum tricarinate, and with an elevated edge; anterior
tibia arcuated.

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-
nate ; penultimate joint also large and triangular, with a slender
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
Ctenistes 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.

distinct, entire ; three dorsal striz entire; fourth and fifth ab-
breviated, not reaching the middle; sutural stria extending
rather beyond the middle ; a slight transverse indentation near
the tip: thighs bright rufous: anterior tibie with two very
prominent entire teeth.

Length one-fourth of an inch.

Var. a. Transverse line of the head not very obvious ; fifth
atria of the elytra obsolete.

This species is rather rare. In its general appearance as re-
spects color, it resembles the sinwatus Panz., which, however, is
destitute of the marginal stria. The variety occurred in Arkansa.

4. H. sreipus.—Thoracic strie entire; marginal and four
dorsal striz entire; an oblique abbreviated stria at base.

Body black, immaculate: head with the transverse line very
distinct ; an obsolete, longitudinal line visible in a particular in-
sidence of light: antenne with [35] the tip of the clavum pale :
thorax, striz entire, not approaching at tip: elytra, marginal
stria entire, near the base exterior to the humerus, bifid and di-
yaricated ; an abbreviated, very oblique stria from the humeral
angle, inwards towards the first dorsal stria; dorsal strize four,
entire ; fifth not reaching the middle; sutural stria extending
beyond the middle; an abbreviated, very oblique stria at base,

rior tarsi threee toothed, the intermediate tooth largest, three
smaller teeth above.

Length less than one-fifth of an inch.

From the character of the fifth stria this species might be mis-
taken for the interruptus of Beauvois, but it is a much smaller
insect, and the cnterruptus has two abbreviated strie at the base
of the elytra.

It is an inhabitant of Missouri; I obtained two specimens
when with Major Long’s party in that region.

5. H. rnpistincrus.—Thoracic striz entire; dorsal striz
four, entire; fifth stria abbreviated, obsolete ; sutural stria slight.

distinct : thorax with an indentation on the middle of the poste-
rior submargin ; lateral strize entire and not approaching at their
tips: elytra with four entire dorsal strie ; fifth abbreviated, more
or less obsolete, generally consisting of five or six punctures ;
sutural stria not deeply impressed, extending [36] rather
beyond the middle, and not reaching the tip: anterior tibiz tri-
dentate, terminal tooth largest, emarginate.

Length less than one-fifth of an inch.

B. Thoracic stria single.

6. H. sEDECIMSTRIATUS.—Dorsal strie entire ; fifth connected
to the sutural at base.

Body black, immaculate: head with the transverse line dis-
tinct: antennze ferruginous, paler at tip: thorax with the stria
entire and well impressed: elytra with the dorsal and sutural
striz entire, the latter uninterruptedly connected with the fifth
at base: marginal strix two, exterior one entire, inner one ab-
breviated at the termination of the small oblique line; terminal
margin with small profound punctures: feet piceous: anterior
tibize tridentate.

Length more than three-twentieths of an inch.

This species is not uncommon, and seems to extend to many re-
mote parts of the Union, as I obtained a specimen in Missouri.
The fifth and sutura! strix of the elytra unite at base as obviously
as those of the 12-striatus of Europe and Africa; it is, therefore,
somewhat similar to the americanus of Paykull, which, however,
differs by being altogether destitute of the marginal striz of the

elytra, and by having two thoracic strz, though one of them is
much abbreviated. It may be useful to state in this place, that
Paykull has represented his americanus as having the sutural
strize widely interrupted at base from the basal termination of the
fifth stria; in this character [37] he is, perhaps, correct, as
respects a few specimens, but in most individuals the connection
can be traced, with the exception of a very short interval of ob-
solete interruption.

7. H. optiquus.—Elytra with an oblique rufous spot at tip ;
lateral thoracic stria interrupted from the anterior one.

Body black: head with the transverse line angulated in the
middle: antennz rufous: thorax, an orbicular indentation at the
angle formed by the anterior and lateral strive, which do not
join: elytra with a large oblique spot on the exterior tip, extend-
ing from the sutural angle to the humerus, where it is obsolete ;
four dorsal stria, entire; fifth somewhat abbreviated, being ob-
viously shorter than the others; sutural stria extending to the
middle: feet with a large, prominent, slightly emarginate tooth
at tip, and three smaller ones.

‘Length more than three-twentieths of an inch.

This is so much like the diémaculatus Linn., of Europe, that I
have long hesitated to describe it, being inclined to consider it a
mere variety of that species. Paykull represents the frontal
stria of the bimaculatus of the usual form, excepting that it is
more obtuse than others, whereas that of our insect is precisely
similar to the same part of the senegalensis Payk., this character,
for which I rely on the accuracy of Paykull, combined with
those of the interrupted thoracic strive, and the somewhat abbre-
viated fifth dorsal stria, justify the separation of this insect as an
independent species. [38]

[Does not differ from the European species mentioned.—LkEC. |

Family 2.—Frontal stria obsolete or none ; lateral thoracic

perceptible and generally abbreviated : stria on the lateral edge
of the superior surface as distinct as the dorsal ones: feet piceous:
anterior tibia ciliated with short spines.

Length one-tenth of an inch.

Var. a. Body piceous.

This species is altogether different from the flavicornis Herbst,
in which are but three abbreviated striz at the base of the elytra.
I therefore adopt a name given by Dr. J. F. Melsheimer. It is
certainly very closely allied to the fulvicornis Fabr., and may
possibly prove to be a variety of that insect.

fulvous capitulum : [39] thorax more obviously punctured each
side: elytra piceous at the terminal margin; marginal stria ob-
solete, more distinct behind ; four dorsal striz entire, and fourth
very obtusely incurved at base, so as almost to join the sutural
stria; fifth stria abbreviated, extending a little beyond the mid-
dle : anterior tibize narrower at tip, and very obtusely and slightly
crenate on the edge.

Length rather less than one-tenth of an inch.

A very distinct species, remarkable for the connexion of the
fourth and sutural strie.

Var. a. Fifth dorsal stria abbreviated, (rare. )

Var. b. Entirely black.

This seems to be closely allied to the troglodytes Payk. of the
East Indies; but in that species the form is more oval, and the

at base.

Length rather more than three-twentieths of an inch.

Var. a. Cupreous dull.

Length less than three-twentieths of an inch.

Inhabits Missouri.

Very closely allied to 4-striatus Payk. of Europe, but the im-
punctured space of the thorax is much smaller, and that of the
elytra is shorter, transversely oval. Not uncommon. It occurs
numerously on the sea beach under Fuci, and other decaying
vegetable and animal substances. I obtained a specimen also in
East Florida.

13. H. mancus.—Thoracic punctures smaller on the disk; a
common space on the elytra, impunctured ; dorsal striz all ab-
breviated ; head without impressed lines.

Body black: head punctured, compressed before and destitute
of rugs: thorax densely punctured ; punctures smaller on the
disk, and particularly behind the middle: elytra densely punc-

punctured ; marginal stria entire ; dorsal strize abbreviated rather
behind the middle; fourth and sutural strize connected at base :
feet piceous-black : anterior tibize not dentated, but with remote
short thick spines.

Length rather less than three-twentieths of an inch.

I obtained it in the North-west Territory during Major Long’s
second expedition. It resembles the [42] preceding, but the
abbreviated first dorsal stria, and the anterior tarsi, amply dis-
tinguish it.

14. H. patmatus.—Thorax, excepting on the posterior mar-
gin, impunctured; anterior tibiz profoundly dentated.

Body black: head with a transverse line and longitudinal bi-
farious one : antennee, small joints rufous: thorax without any ap-

16. H. rronraris.—Head a little depressed; nasus very
short, transverse line indistinct; elytra with entire striae.

clypeus terminating before in a rather prominent line between
the antennz; transverse line obsolete ; nasus very short, trans-
verse, linear, not concave: labrum and mandibles piceous: an-
tenn piceous, with a yellow capitulum : thorax subequally punc-
tured: elytra slightly punctured on the lateral margin and tip ;
striz entire; fifth obsolete at base, or continued only by punc-
tures : anterior tarsi with four small teeth.

Length less than one-tenth of an inch.

Very similar to the preceding, but much smaller, and distin-
guished by the peculiar form of that part of the head to which
the labrum is attached; this part is transverse linear. I ob-
tained a specimen on the eastern shore of Virginia.

intermediate pairs of tibize five-toothed, of which the superior
tooth is very small, and with the appearance of a still smaller

This is very similar to 7. depressus of Europe, but there is no
appearance of punctures on the thorax.

merous ; a very slight appearance of a marginal stria, and of one
or two oblique abbreviated ones at base: anterior tibiae somewhat
dilated, teeth four, obsolete ; posterior tibiz unarmed.

Length three-twentieths of an inch.

To the unassisted eye, the elytra appear perfectly smooth, and
it is only on a close examination, aided [45] by a particular in-
cidence of light, that the strize we have described are at all visi-
ble. In some specimens, the anterior tibiz are hardly crenate,
in others they appear armed with four very short spine-like
teeth.

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. Melsheimger, I 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 pyradis 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 al) 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.

ed, with short hairs, somewhat inequal; lateral margins nearly
obsolete behind, depressed before ; posterior margin abruptly de-
pressed ; anterior margin regularly rounded, lateral angles none:
scutel pale rufous: elytra plumbeous and decidedly sericeous,
varying with the incidence of the light: beneath pale rufous,
sericeous : anterior tibiz simple.

Length nearly three-fifths of an inch.

The colors of this species, as well as their distribution, are so
very similar to those of the preceding, that it might be easily
mistaken for the same, but it differs in the anterior rotundity of
the thorax and the simplicity of the anterior tibie.

the length of the fourth ; mouth prominent, with a black line!
each side above; palpi long, terminal joint but little dilated:
thorax quadrate, not transverse; lateral edges rectilinear; angles
rounded, posterior ones more acutely so; a broad black vitta,
which, however, does not affect the anterior and posterior raised

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 antennze
are less elongated, the thorax is less contracted before, and the
strie of the elytra are much narrower. The name given by Mr.

Although the antenne differ considerably from the character-

joints to the tarsi, I have thought best to place the present in-
sect in the genus Hnoplium.

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 mortworum 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.

form of a V, the angle pointing towards the base: beneath black-

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 ;
strie 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.

APHODIUS Illig. Fabr.

A. viTTatus.—Black ; clypeus trituberculate ; elytra with a
dull rufous vitta.

Scarabzus vittatus Melsh. Catal.

Head minutely punctured ; three tubercles placed in a trans-
verse line, the intermediate one largest, and the lateral ones elon-
gated in a line to the eye: tip of the clypeus slightly and very
obtusely emarginated: thorax with numerous small punctures :
elytra with narrow punctured striz ; the interstitial spaces flat ;
a dull rufous vitta including the humerus at base, [192] extend-
ing somewhat obliquely towards the apex of the elytron, and con-
tracted in the middle: feet obscure rufous.

Length more than three-twentieths of an inch.

This insect is very like the terminalis nobis, but it may be dis-
tinguished by the vitta of the elytra, and the much less pro-
foundly emarginated clypeus.

TROX Fabr.

1. T. stRIATULUS.—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 ofan 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

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 distinct 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]

It may be compared with the S. punctatus Fabr. of Southern

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 M. quercina in being more cylindrical,
from M. quercus, in the absence of the “rore coerulescenti,” 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.”

2. M. epuitipa.—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. J 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 angu/aris, 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 vollig mit der kalkerde iiberein kémmt; 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.

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 M. liberta

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.

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-
guished ; 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
striz on the elytra.

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 strie 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

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.”

HOPLIA ITllig.

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 ]

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 spets 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 ]

a dilated indentation each side anterior to the eyes: antenne 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 IJ find the sides of the thorax to be a little
more rounded than in the European specimens.—LEc. ]

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

more obviously cupreous, with punctured striz : 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.

Body bright copper, polished; punctured: antenne long,
blackish ; third joint equal to the fourth and fifth together,
which are equal; labrum piceous: eyes moderate: thorax de-

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 Al/e-
cula of authors.

2. C. aTRA:—Blackish-brown, with short hairs; striae 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; antenne 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
-yufo-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 striae.

[The name having been previously employed, this species has
been described by Dr. Melsheimer as Allecula nigrans.—L«xc. |

2. A. BIFAscIaTUS.—Rufous ; elytra with a black band and
tip.

Head darker than the thorax: antennz and palpi paler than

Length one-tenth of an inch.

Comes near to basilaris nob.; but, in addition to its difference

1826.]

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 °
Ferté A. bizonatus; it does not, however, appear different from
his A. cervinus.—LEC. |

suture, blackish.

Head and thorax pale ochreous; the latter with a moderate
longitudinal groove, and gradually narrowed towards the base ;

band on the middle much dilated on the exterior margin, and at
the suture; on both of which, it extends in a narrow line to the
base and tip; punctures not distinct ; beneath pale rufous; feet
whitish.

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.

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

Inhabits Pennsylvania.

Mouth, antennz, 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 lugubris, 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.

ANTHRIBUS Fabr.

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-

[I have a species of Hylesinus which agrees with this descrip-
tion, but the elevated punctures are hardly more distinct at the
tip. Phleotribus liminaris also agrees, except that the front is
concave with two distant small acute tubercles.—LeEc. ]

APATE Fabr.

A. punctatus.—Black-brown: posterior declivity of the ely-
tra carinate on the exterior submargin.

Apate punctatus Melsh Catal.

three exterior joints yellowish, decidedly transverse: thorax be-
fore rough, with elevated, thick points, which disappear towards
the base, and are there supplied by discoidal punctures: elytra
with large, impressed punctures, which can hardly be traced
into a series; tip rather abruptly declining, [ 259] with prostrate
yellowish hairs, and a carinate line on the exterior submargin.

Length more than three-twentieths of an inch.

CLYPEASTER And. Latr.

C. rasctaTus.—Thorax yellowish, with a dusky disk; elytra

the edge of the tip somewhat dull yellowish: beneath dusky:
feet honey-yellow.

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

Length about one-twentieth of an inch.

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.

3. L. HaMATODES.—Thorax with two indented lines; elytra
with large, deep punctured strize.

Lyctus hematodes ? Fabr.

Body dark reddish-brown, a little depressed: head [263]
with large, not profound punctures; an indented longitudinal

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 ZL. hamatodes
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.

SYNCHITA Hel.

1. §8. 4-aurrata.—Blackish-brown ; thorax canaliculate ;
elytra each with two rufous spots.

Inhabits Arkansa and 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, and a marginal groove, containing
but a single series of transverse punctures; interstitial lines

spot at base, and another beyond the middle.

Length less than three-twentieths of an inch.

I obtained three specimens when with Major Long’s party in
Arkansa, and several occurred in Florida.

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

Inhabits East Florida. [ 267]

Body blackish-brown: head granulated, somewhat rufous
before: antennz 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.

CUCUJUS Fabr.

1. C. BIGuTTATUS.—Dark reddish-brown ; antennz more than
half the length of the body; elytra with a large spot; thorax

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 strie: 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 Laemophloeus.—LEc. ]

2. C. MopESTA.—Reddish-brown ; antennz more than half
the length of the body; thorax with a lateral impressed line ;
elytra with punctured strie.

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. It is 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.

Body brownish: antenne 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 sevyen-twentieths of an inch.

This species resembles the preceding, but it may be distin-
cuished 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 LZ. 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.—L«c. | [270]

3. L. pAsycerus.—Antenne hairy beneath; elytra with
minute elevated points.

Body light brownish-cinereous : antennze a little longer than

nal, approximate, brown lines: elytra with a commom arcuated
black line, extending from one humerus to the other; numerous,

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.

acute at tip, each side before the posterior angles, which are
emarginate; posterior margin with a transverse indented line:
seutel 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.

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...

Length more than three-fifths of an inch.

The spines on the inferior surface of the antenne, are not

This insect is not uncommon. It is related to S. 4-maculatus
Fabr., S. maculosus Fabr., S. didymus Oliv., all of South
America, and S. 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 antennz more hairy than the
other joints ; from st¢gma by having the basal spot of the elytra
double.

1. L. scALARIS.—Rufous, sericeous; elytra slender, with
sericeous triangles along the suture.

Body elongated rufous, more or less covered with golden seri-
ceous ; impunctured : head with a transverse indentation before,
and a longitudinal indented line; space behind the eyes promi-
nent: ar>*ennze rather more than half the length of the body:

For this fine species I am indebted to my friend, Prince
Musignano, who obtained it near his summer residence, at Point
Breeze, New Jersey. It is much like the Cerambyzx longipes of

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. rrIpLA.—Rufous ; feet yellowish ; thorax dentate each

This species is nearly equal in size to the palmata Oliv., 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 antennz nearly double the length of the second, and
the tips of the elytra more profoundly emarginated; the thorax
is moreover transverse. I may observe, with respect to the
palmata, that the male only has the anterior tarsi dilated.

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. rrivirrata.—Blue-black ; margin of the thorax and two
elytral vitte yellow.

Body punctured: head entirely blue-black, with an impressed

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.

Thorax cinereous, tinged with rufous on the back, each side of
which is a fuscous somewhat undulated line, confluent with the
margin behind the middle; exterior to the fuscous line is a
cinereous arquated line within which is an abbreviated marginal
fuscous line: back not much elevated, simple; tip terminating
more obtusely than usual and with a cinereous spot above:
hemelytra hyaline, with a dusky base, and fuliginous spot in the
middle and at tip; nervures margined with brown; terminal
cellule smaller than either of the two adjoining ones and trans-
verse : thighs blackish.

13. M. BeLiicera.—Thorax with a projecting horn; tip
slender, acute.

Inhabits Pennsylvania and Florida. [ 303 ]

Thorax green, with small, fulvous spots; a compressed horn
before, which is not in the slightest degree arquated, at its ex-
tremity rounded; back not carinated, but with an impunctured
line; tip slender, and equally slender when viewed laterally as from
above, acute: hemelytra hyaline, at base varied with green and
yellow ; terminal nervure about three times longer than wide.

Length to tip of hemelytra and tip of the horn half an inch.

Resembles bimaculata Fabr., but the tip of the thorax is much
more attenuated and acute and the terminal cellule of the
hemelytra is elongated.

In adddition to the bimaculata F., sinuata F., emarginata F.,
we must place in this genus, his Centrotus bubalis. The Centro-
tus acuminatus of that author, is only the female of his Membra-
cis bimaculata. His sinuata does not appear to me to differ
specifically from the emarginata.

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.

with a lateral vitta, which is gray, and becomes gradually yellow
to the tip; beneath [21] with a yellow lateral vitta, being a
continuation of the posterior line of the pleura, and becoming
obsolete behind.

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.

[Vol. VIII.

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 algo are dissimilar.

[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.

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 LZ. Lydia Drury, 2, pl. 47, fig. 1, must be restored
to this species, as the other L. Lydia of the same author had been

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 having 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.

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 I. marginata Degeer. Wings fuscous from the
base nearly to the middle.

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 por-
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.

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.

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 vittz 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.

This beautiful little insect is very common. When irritated,
it diffuses a strong offensive odor, similar to that of human ex-
crement. 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.

Series, vol. 1, 1818, pp. 401-426. ]

A Monograph of North American insects, of the genus CICINDELA.
Read, 7th November, 1817.

It 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 these 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
alichting 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

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 animated 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. Ctcindela,
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, Cicindela 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, [ 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 Carabi, 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 Nottophilus there exists the spine and
recipient cavity of Elater. Colliwris is composed of two species,
natives of the East Indies, and one of South America, distin-

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. dabiata. 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.

every particular with the short description of that insect in the
Syst. Nat. and also in the Syst. Hleut., 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 trifasciata, the most important of which “on voit une raie
interrompue, le long de la suture, jusque vers le milicu,” is
with respect to our insect a [411] good discriminative charac-
ter, in which this line or vitta never has existence; the size also

whereas that of the vulgaris is full three-fifths. From these
characters it must be evident that Olivier’s ¢rifasciata 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 tri/asciata ; 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 generie 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, pune-
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-
timorensts Herbst., (repanda Dej.)—LEc. |

Inhabits the southern States.

Dec. Head entirely rugose, neck above granulate; clypeus
narrowed in the middle; labrum much broader in the middle,
white, edge brown, strongly thrée-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
inarginal 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, venter 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. wnipunctata 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, I shall consider it as the same until those
who have an opportunity of seeing the original may decide.

nal blackish punctures each of which latter furnishes a hair ;

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. Each 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.

Length nearly three-fifths of an inch.

Inhabits New Jersey.

Desc. Head bronzed, naked, edges green; antenne 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 and a 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-
le 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

covered with dense hair; palpi white, terminal joint of each
black at the tip. Trunk, on each side cupreous, concealed by short,
cinereous hair ; thorax bronze or olivaceous, posterior impressed
line green or reddish ; elytra olivaceous-obscure, or tinged with
cupreous, margin pale, uniting the anterior and posterior lunules,
the former with an accessary spot atthe 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 ¢rist’s, and seems to be alienated from it, only by the
presence of an intermediate dot and terminal line; the central re-
clivate band is precisely the same in form. Nevertheless it is
highly probable that the ¢ristis is a distinct species, although for
the present I have placed it here as a variety, having no oppor-
tunity of examining a specimen.

small white dots, of which three are on the disk arranged in an

A very common insect, its variations are confined to changes
in the number and magnitude of the spots of the elytra; the
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.

This is the smallest of our species, being less than punctulata,

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 :-—

same, or only a variety of it, for it is as characteristic of that
species as it can be of any other.

Vol. 2, No.1, 1823.]

Descriptions of Insects of the Families of CARABICI and HYDROCAN-
THARI of Latreille, inhabiting North 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 Linnzan genus which occupies the first station in the improved
classification of Latreille.

I now proceed to lay befere the Society descriptions of such
of our native insects, as were included by Linneé, in his three
genera, Carabus, Dytiscus, and Gyrinus. The two former of
these, but more purticularly the first, are now considered as great
families, constituting numerous genera, and agreeably to the or-
der in which I have enumerated them, immediately succeeding
the Cicindeletx, 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 thoge published by Germar in bis Sp.

436 TRANSACTIONS OF THE

The Carabii 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 Dytiscii are much less numerous than the preceding, but
are equally nourished by animalfood. 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 Dytisci’, 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 movements 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, [ have carefully referred to those collections from which I

[Vol. II.

AMERICAN PHILOSOPHICAL SOCIETY. 48

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, [ have been anticipated by the labors
of this, or any author, [ shall immediately relinquish my claims,
and do justice to the real discoverers, when their labors shall
meet my eye.

To the inflexible Linnzan 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-
nzus,) 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 Linnzan method.

The modern entomologist will readily perceive that T 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.

This was sent to me by Dr. J. F. Melsheimer ; I have not found
a specimen, and therefore have considered it as a rare [ 10 ] spe-
cies. The name prasinus having been already applied to a dif-
ferent species has rendered it necessary to change it.

[Belongs to Calleida, and described by Dejean as OC. margt-
nata.— LEC. ]

If the figure given by Olivier be correct, the specimens [13 ]
here described must be considered a variety. Several individuals
were brought from the Missouri by Mr. Nuttall. They are
occasionally taken in Pennsylvania, on flowers. When recent,
it is of a much more bright red than when long preserved in the
cabinet. The red becomes pale and the white vitta yellowish.

Caught in Mr. R. Haines’s garden, Germantown.

3. L. ATRIVENTRIS.—Ferruginous ; elytra deep purple ; venter

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 ; strie acute, distant; two large subtriangular or
subovate 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. 3. 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 occur
enlarged, so as to be confluent with the apical margin. It

[Vol. 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

convex, obtuse; margin blued-purple, with a regular series of
minute, elevated, ocellate granules.

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
copy of the work from Paris.

A large species by no means common. I think it highly prob-
able that the 4-maculatus of Palisot is no other than this insect ;
if so, the spots of the elytra, and especially those of the base, in
his figure, are by far too distinct ; indeed, the former are always
obsolete and sometimes not at all visible.

This resembles Scarites gibbus, of which no description has

same figure of Fuess. Arch. the 17th of plate 29, has been refer-

therefore that they are one species, particularly as Herbst calls it

angles more acute, feet much paler, and the thorax more dis-
tinctly transverse.

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 cenus,
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 Hpomis, &c., did not that author expressly
state that insects of that division ought to have the two anterior
tarsi only of the male dilated.

smaragdulus having been appropriated to a very different insect,
I have substituted that of basillaris. It belongs to the genus
Amara of Bonelli.

whether this species or the next was the true pallipes Fabr., had
it not been for the specific character “ thorax rotundatus” applied

of the former with a dusky carina; thorax impunctured, widest
in the middle, a very little narrowed behind by a regularly
curved edge, base nearly as broad as the elytra, basal angles rec-

antennz is not confined to the third joint, but is extended to
the second and first, and is very definite and striking ; but the
character attributed to that genus of “ thorax [66] narrowed be-
hind” is not sufficiently obvious in our insect. Wings perfect.

antennz with ferruginous hair towards the tip; beneath green ;
tooth of the labium very short, hardly prominent; thorax im-

This species makes a very near approach to the sycophanta of
Europe ; but, as Dr. Leach observes, it differs from that insect 1n

basal line; elytra black, striz reticulated by smaller transverse
lines, which, near the base, are much more deeply impressed, so
as almost to granulate the interstitial lines; striz fifteen, trans-

golden dots, and a solitary one near the scutel, exterior marginal

of the abdomen with rather larger punctures.

I was formerly misled respecting this insect by that portion of
the specific description of Fabricius which ascribes to it an apte-
rous character. In this error I was corrected by Professor
Wiedemann of Kiel, who assures me that Fabricius was mistaken,
and that his species is certainly winged.

CARABUS Lin. Latr.

Anterior tibiz entire; elytra entire ; exterior maxillary and
labial palpi subtriangular, dilated; mandibles not elongated,
robust; labrum short, transverse, bilobate; labium profoundly
emarginate and with a central tooth; antenne, second joint half

tips; palpi, terminal joint dilated ; thorax margined, margin vio-
laceous, gradually more recurved to the posterior angles, very ob-
tusely rounded, slightly extending backwards beyond the basal
line, base depressed and with the lateral margin somewhat scabrous,
dorsal line obsolete, basal lines wanting ; elytra black, margin
violaceous, disk nearly smooth with about thirty striz of minute

Carabus granulatus Melsh. Catal.

Head black ; antennz and palpi deep piceous, the former fus-
cous towards the tip; thorax black, with numerous, minute, in-
dented punctures, which are obsolete on the disk, dorsal and
basal lines conspicuous, margin towards the posterior angles
slightly reflected, posterior angles rounded, prominent behind the
basal line; elytra black-bronzed, striae with a somewhat lateral
series of punctures and numerous elevated ones, interstitial lines
fifteen, two of which are more conspicuous, fourth, eighth, and
twelfth interrupted, interrupted lines acute behind, a submar-
ginal series of elevated punctures ; feet black ; venter deep pice-
ous or black.

The impressed punctures of the intervening lines of the [77]
elytra are sometimes obsolete or wanting. This species does not
agree with the description of C. granu/atus either as respects the
color of the antenne 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.”

This insect very much resembles C. interruptus, but differs in
the form of the punctures of the elytra and in haying this part
margined with purple; the form also is less elongated.

Carabus catenatus Melsh. Catal.

Body black, glabrous; head smooth, impunctured ; antenne
fuscous beyond the middle ; thorax, exterior margin obscure vio-
laceous, and with the base somewhat scabrous, disk impunctured,
dorsal and basal lines obsolete, the latter oblique; elytra mar-
gined with obscure violaceous, edge near the base slightly serrate,
interstitial lines about fifteen, obtuse and smooth, connected by
numerous transverse septa, which are equally prominent and ob-
tuse, not continued, fourth, eighth, and twelfth line dilated, in-
terrupted, obtuse. Postpectus and venter each side punctured.

The name catenatus has been applied by Panzer to a species
inhabiting Carolina.

labial palpi with the last joint clongated, subcylindrical, the
latter of equal joints; tongue not longer than the labrum, and
not tricuspidate at tip; labrum entire; labium profoundly emar-
ginate, and with an emarginate, obtuse, central tooth ; mandibles
not dilated at base ; thorax truncate, cordate ; abdomen oval, de-
pressed; antennee filiform.

AMERICAN PHILOSOPHICAL SOCIETY. 495

Body black, glabrous, depressed ; head with two obsolete pice-
ous spots on the vertex; mouth piceous; palpi paler at base;
antennz 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-
terior margins depressed, [79] lateral edge reflected, dorsal line
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 very 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.

OMOPHRON Latr.

Tongue very short ; antenne filiform ; maxille ciliated on the
exterior side; body short, nearly hemispherical; thorax trape-

Body glabrous, beneath black ; head black ; antennee brown ;
base and palpi testaceous ; nasus and labrum piceous; thorax
rufous, rounded behind, dorsal line distinct, continued to the
base, posterior lines excavated, dilated, and punctured, a few

what darker on the disk, striz impunctured ; pectus rufous ; ster-
num black; feet testaceous ; postpectus and abdomen black. [91]

Very closely allied to the preceding, is less common, and is
distinct by the punctures of the thorax, by the less abrupt poste-
rior termination of that part, and by the consequent less obtuse
form of the angles.

yellow margin, there is an oblique subterminal line, as in D.
marginatus, but it is very distinct from the latter species, by not
having the yellowish anterior and posterior thoracic margins.

lines.

Var. a. Above dark reddish-brown, margin paler, spots yel-
low, distinct, piceous ; feet pale rufous. Z

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. Ihave 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.

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, Xe. 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. *

G. americanus Dr. Forsberg, Trans. Upsal Society.

Body oblong, subovate, blackish, slightly tinged with bronze
or purplish, beneath piceous ; head, labrum deeply ciliated with
white hair; thorax impunctured, scutel none; elytra with very
minute obsolete, distant punctures, disk plain, each side with
four or five obsolete striae, tip distinctly and very obtusely
sinuated, a projecting angle at the sutural tip ; poststernum with
distant profound punctures before ; feet testaceous, anterior pair

very similar to that of the flowers of the Calycanthas.

before, punctures profound and distant; feet, posterior pairs
testaceous, anterior pair in the 4 furnished with a prominent
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 having 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
of the male and by the simply rotund termination of the elytra
in both sexes.

3. G. ANALIS.—Black, slightly bronzed; elytra with punc-
tured strize; thorax with a transverse indented line.

Body beneath impunctured and tinged with piceous; front
between the eyes with two impressed dots; labrum at tip and
palpi at base ciliated with white hairs; mouth beneath piceous ;
labial palpi testaceous, blackish at tip ; thorax with a transverse
indented line rather before the middle not attaining to the lateral
margins, and a short oblique line on each side behind it curving
towards the lateral edge; scutel distinct, subtriangular [109 ]
elytra with about eleven distinct narrow striz of punctures, in-
terstitial lines depressed, each elytron very obtusely rounded at
tip; poststernum impunctured; feet rufous; caudal segment
testaceous.

A. cYLINpRIFoMIs Say, (Manticora) Journ. Acad. Nat. Sci.—
This insect, which I found near the Rocky Mountains, I de-
scribed under the genus Manticora, but judging by the present
mutilated state of the specimen it seems to agree better with the
Megacephala. Vt 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.

Of this genus I have in my cabinet twenty-two species, natives

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; antennz 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; tibie, 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 Cici-
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 tibize 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 I 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 Carabidzx, 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
antennz, form of palpi, ligula and mandibles, prove conclusively
that it enters the group Pzederini. 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—Luc.]

CASNONIA Lair.

C. rurIpEs 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.

Odacantha dorsalis Faby. 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.

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 antenne, Xc.

Can this be the janus, or is the quadripennis Dej. synonymous
with that species described in Turton’s Linn. ?

CLIVINA Latr., Dej.

1. C. BrpustuLATA 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 Beauyois.—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.

description ; but in addition I may add that it varies in having a
large obscure rufous spot on the vertex.

8. 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. EH. ruLiatnosus.—This new species was found in Pennsyl-
vania by Mr. Le Sueur, to whom I am indebted for the specimen ;
and although the head and thorax are destroyed, yet sufficient
character remains to prove it the analogue of the £. uliginosus,
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-

ber. The body is slightly larger than in that species. It ap-
pears to be rare.

[This is perhaps E. cicatricosus Lec.—L«Ec.]

2. E. ruscartus.—This species I described in the Trans.
Amer. Philos. Soc., with a mark of doubt, as the L. 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 riparius, 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 all agree, 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 WV. 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 elytra]
puncture is small, and like that of aquaticus, 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.—WN. 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 fect
are entirely rufous, even including the thighs. The head is
larger than that of the semistriatus, 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.

O.? PARALLELUS.—Black; thoracic angles rufous; feet pi-
ceous.

Inhabits Louisiana.

Body black, very slightly tinged with piceous; head with but
a slightly impressed point between the antennz; antenne red-
dish brown, three basal joints honey yellow ; palpi honey yellow;
mandibles piceous ; thorax narrowed before, smooth, dorsal line

distinct, not extended on the margins; basal lines distinct, ob-
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 striz continued parallel to the tip, well impressed, minutely
punctured; interstitial spaces depressed, third with a single
slight puncture on the posterior fifth from the base ; beneath
black ; posterior 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 terminatus or Calathus gregarius 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.

about three punctures, excepting the middle one, hardly distinet
from the punctures of the strize.

Body black, polished, glabrous, with a few, rather long,
marginal [422] hairs; head impunctured; base of the first
joint of the antenne, of the mandibles black-piceous ; antennze

impressions between the eyes rather deep; thorax rather short,
wider than long, subquadrate, impunctured; lateral edge regu-
larly curved; margin slightly elevated, narrow, broader towards
the posterior angles ; dorsal and anterior lines distinct ; posterior
lines dilated, suborbicular, slightly rugous ; posterior angles very
obtuse ; anterior and posterior margins subequally broad ; elytra
with acutely impressed striz, regularly punctured; punctures
small, obsolete towards the tip ; third interstitial line with three
punctures, two at the third striz and the terminal one at the
second strie; interstitial lines much depressed; tibia, tarsi,
knees and extreme base of the thighs piceous.

Length seven-twentieths of an inch.

This species is rather more robust in proportion to its length
than the other American species. The thorax is much broader
and shorter. The species is perhaps more like scutellaris Say,
than any other ; that insect is remarkably depressed about the
region of the scutel.

AGONUM Bonelli.

1. A. suTURALE.—Green, polished ; suture cupreous.

Inhabits Mexico.

Above metallic green, polished, impunctured; head with a
slight coppery reflection ; labrum, antennz and palpi blackish :
thorax varied with cupreous; dorsal line and basal dots obviously
indented ; elytra with very slender striz ; interstitial spaces wide
and plain, first one cupreous, third with three punctures, equidis-
tant, basal one on the third strie, middle one on the second
striee ; beneath piceous black; cox piceous.

Length three-tenths of an inch.

This is a brilliant species, equalling in this respect the 8-punc-
tatum Fabr., and errans nob. and but little inferior to cupripenne
nob., all of which, together with nutans nob., belonging to this
genus, although I referred them to the including genus Feronia,
Latr. The cupripenne nob., is equal in splendor, though not in
magnitude, to the 6-punctatum Fabr. In comparison with parum-
punctatum F., the form is more robust, thorax more brilliant,
wider, and is as wide at base as anteriorly ; the interstitial spaces
also are much more flattened. [423]

2. A. ORBICOLLIS.—Black ; thorax rounded ; third interstitial
line with three punctures.

Inhabits Mexico.

Body black, polished, impunctured; antenne
joint and palpi piceous; thorax orbicular, truncate before and
slightly so behind; lateral edge regularly arquated, not depressed,
but with a simple and equally elevated edge ; dorsal line obsolete,
anterior and posterior transverse lines obsolete ; basal impressed
lines or dots distinct; elytra with well impressed striz, which
are crenate, not punctured ; interstitial lines convex, the third
from the suture with three equidistant punctures; feet piceous ;

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 me/anarium 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 viduwum, 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, &e.

impressed ; base a little emarginate, not wider than the abdomi-
nal petiole ; elytra with punctured, not deeply impressed striz,
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. L/ligeri Panz., but the thorax of that spe-
cies is not so narrow at base, and its elytral striae 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 tenebricosa 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 strize 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. Jiligeri Panz., but aside from color, it may
be distinguished from the obsolete lateral striae, the much less
dilated thoracic basal lines, Ke.

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 F., 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 posterior 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 strie, 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 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.

convexity, nearly flat; near the lateral tip slightly and rather
acutely sinuated ; tibie and tarsi-piceous.

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 antennee
as strongly contrast as those of A. vulgaris F.

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 ;

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, &e. [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.

For this insect Iam indebted to Dr. Harris. On a cursory
examination I considered it identical with WS. ochropezus Say,
notwithstanding its great inferiority of size, which may at once
distinguish it. The thoracic posterior angles are much more ob-

are much more numerous and extend nearly to the basal middle,

analogue of paludosum, it belongs to the genns Bembidium, as
at present restricted.

2. B. nongestuM Say, Trans. Amer. Philos. Soc.—When de-
scribing 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.

thoracic lines are much dilated.

5. B. coxenprx Say, Journ. Acad. Nat. Se. 3, 151.—An-
tennz with three basal joints and base of the fourth pale yellow-

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 Meg.

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

tenne fuscous, piceousat 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 ; striz somewhat dilated, and
with dilated, quadrate, profound punctures; strize 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 strie 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.

HYDROCANTHUS Say. [447]

H. ATRIPENNIS.—Ferruginous ; black.

Inhabits Mexico.

Head and thorax ferruginous; the former with an oblong tri-
angular, obsolete, darker spot between the eyes, and the latter
with an impressed line on the lateral submargin ; elytra blue-
black, immaculate, impunctured ; pectus, as well as the head be-
neath, dull yellowish ; sternum flat, at its anterior tip acute, but
not prominent, dusky; postpectus blackish, dull yellow at tip ;
feet, intermediate and posterior pairs blackish, slightly varied
with piceous.

Length less than one-fifth of an inch.

This is the second species of this genus; the first I published
in the Trans. Amer. Philos. Soc. vol. 2, new series. The genus
is allied to Noterus Latr., but the labial palpi are much more di-
lated, and have no appearance of emargination.

1. G. emaroinatus Say, Trans. Amer. Philos. Soc.—Since
described by Germar under the name of vittatus, Spec. Nov.

2. G. ANALIS Say, Trans. Amer. Philos. Soc.—Germar is of
opinion that this is the same as natator I’.; but on comparison, I
find it to differ in many small characters, the most obvious one
of which is the color of the epipleura, that of the natator being
light piceous, whilst in the analis it is of a bronzed black, &e.
It is no doubt a closely allied species.

3. G. optusus.—Black ; feet honey-yellow ; behind obtuse.

Tnhabits Mexico.

Body black, polished; head with two indented dots between
the eyes; mouth piceous ; antennz piceous-black ; thorax with
the anterior lateral, posterior lateral and medial impressed lines
very distinct; elytra obtuse behind and widely truncate; near
the tip obviously depressed ; punctures well impressed, in regu-
lar series, the intervals not impressed; beneath dark piceous,
somewhat paler on the edges of the segments; feet and tip of
the venter honey-yellow.

Length over one-fifth of an inch. [448 }

It may be distinguished from the analis and limbatus nob.,
and from the natator Fabr., and marinus Gyl., in being more ob-
tuse behind and the consequent greater truncation of the elytra.

4, G. pARcus.—Black ; feet honey-yellow.

Inhabits Mexico.

Body rather robust, black, highly polished ; head with two in-
dented, oblique lines between and before the eyes: thorax with
the impressed lines very obvious; elytra with very distinct, well
impressed series of punctures, the intervals not at all impressed ;
tips obtusely rounded ; feet honey-yellow.

Length nearly one-fifth of an inch.

In comparison with minutus Fabr. this species is a little longer
and much more robust, more highly polished, and the impressed
lines of the thorax and dots of the elytra are more profound and
distinct. It is somewhat smaller than either of those I have
before described, and the punctures of the elytra are, notwith-
standing, larger.

depilia,” but my specimens certainly have prostrate hairs on the
elytra as well as on the scutel. If this is not in reality Graven-

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, SS. cyanop-
terus, will be an appropriate one: Fam Ist.

losus as the true name, although it was given by himself a year -
after the Fabrician name.

11. S. vionacrus Gravy.—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,

Ist.

13. 8. ATER Grav.—-In my cabinet I find that I formerly
placed this species under the genus Astrapzxus 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 Astrapeus, 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.

Gravenhorst considered this insect as specifically identical
with his piceus, but in his remarks on that species he states that
“huic Oxytelo alius affinis est, quam D. Prof. Knoch O. sculptus
nuncupayit. Differt thorace lateribus subrotundatis, basin versus
paulo angustiore, coleoptris breviore et paulo angustiore, fusco
seu rufo; coleoptris quadratis, rufescentibus seu piceo-rufo.”
These differences of character indicate a difference of species.
It is the A/eochara sculpta of Melsheimer’s Catalogue.

2. O. RUGULOsSUS.—Black; longitudinally wrinkled; elytra
obscure piceous.

Inhabits Mexico.

Body black, rather short, with numerous punctures, somewhat
confluent into longitudinal wrinkles; head with three grooves,
rather slightly impressed, the lateral ones dilated; antenne
brown, dull honey-yellow at base; palpi dull honey-yellow ; tho-
rax with three grooves, of which the middle one is wider before
and the lateral ones wider behind ; each side a little concave,
the edge slightly reflected: anterior [461 ] angles acute ; lateral
edge arquated; rounded behind; elytra transverse quadrate,
blackish piceous; tergum with dense minute punctures ; feet
honey-yellow.

Length less than one-tenth of an inch.

This does not altogether agree with the var. a. of the carinatus
of Gravenhorst, and to which he has given the name of insignitus.
The present species is proportionally much shorter than the cart-
natus. It is not more than half the length of that species. It
is more than probable that the insignitus is also a distinct
species.

I obtained three specimens of the rugulosus in Mexico.

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. tatipes Gray. Monog. Coleopt. Mier., p. 198.

In the present state of the science, the dafipes can no longer
remain in the genus Oxyte/us, as a species of which Grayenhorst
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. 154) 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 hoe micropteron Tachinis
adjungeremus. Oxytelis autem, sicut hue usque determinati
erant, ob characteres per systema artificiale constitutos, haud
adsociari potest. Kodem ergo jure, quo Astrapael genus olim a
Staphylino disjungebatur, quibus attamen simillimum est, hoe
etiam insectum genus noyum, ab Oxytelis separatum, conderet,
nisi regula systematis naturalis, i. e. character totus externus
seu habitus totus, dissuaderet.” [463]

6. B. HyBeRNATA F.—From the specimen in my collection,
I am led to believe that the hybernata F., 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. onnatTA.—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 having 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.

11. B. rusutus 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 seutel, &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 thoracie edge. It is the
solvulus 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 geranti. +

13. B. weepira.*—Elytra bluish-green, grooved and punc-
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 wltramarina; 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 striz 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 impedita 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 coste, 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; 2. wltra-
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—Lxc.]

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 disc 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.

is A. guercata, the other a variety of A. viridicornis.—LEC.]

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 ein
but the acute, arcuated elevated line at the posterlor angles, 18

similar to that of the /inearis 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
thoracie angles, but the antennz 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

The above species of Agrilus, excepting the first, I described

oblique and dilated; more or less tinged with cupreous; an areu-
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 reflec-
tion from the remainder of the surface. In some positions they
are hardly obvious; but seen from before or behind they are dis-
tinct, 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 rujicollis,
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 Jateralis, 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-

margin, and another each side of the basal middle ; elevated line
of the posterior angles less than one-fourth of the length of the

frontal punctures are obsolete, and the elevated line of the thora-
cic angles is much shorter and less distinct.

12. A. coairans Weber.—The thorax is described to be

rest the tarsi are applied to the outer edge : preesternum promi-
nent to the mouth, and behind applied evenly to the poststernum
by a transverse line.

This genus differs from 7raehys in the thorax being not lobed

1. E. opnxssus 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
occupies 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
oblessus.

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 ig
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 S., 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, &e.

Body black-brown, punctured, rather slender : clypeus concave,

edge not arcuated; a little narrowed before, and contracted at
the spines ; spines excurved, acute: scutel rounded behind: ely-

ance of strie, the series alternately larger : pectus, tarsal grooves

obvious.

The thoracic fissures readily distinguish this species. I formerly
marked it in my cabinet interr ogatively as the brevicollis Herbst ; but
it can hardly be that species, as no notice_is taken of the fissures. Can

color, and a little different in form; being less attenuated be-
hind; in size it is much the same; it is also somewhat more ob-

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. : e

BRACHINUS Weber.

B. ALTERNANS? Dej.—A specimen occurred near New Or-
leans, which, so far as I have been able to compare [152] the
characters, nearly corresponds with this species ; but as the head
is deficient in the specimen, I cannot determine positively ; and,
furthermore, the circumstance of the second and fourth elytral
costa 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 strix, 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 tibie are quadrilateral and denticulate, and the
tarsi beneath are clothed with very dense hairs. In our insect
the conformation of the antenne 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 tibiee
dre 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.

To this genus, as I now understand it, belong several species,
which I published under the genus Malachius ; such as termi- .
nalis nob., &e.

TILLUS Fab.

T.? TERMINATUS.—Black ; terminal joint of the antennz 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.

I 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-
tenne seems to require a separation from the other species, at
least in a distinct subgenus.

It varies in having the rufous thoracic margin very narrow
and even interrupted on the lateral margin.

PRIOCERA Kirby.

P. rvorNATA.—Black-piceous ; antenne and palpi yellowish ;
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
strize : coxe 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.

[Belongs to Cymatodera.—LEc. ] [162]

middle and a narrower one near the tip; more obviously and
densely punctured at base: feet black.

Length two-fifths of an inch.

Very different from C. ichnewmoneus F., and trifasciatus §.

pectus with a black middle.

Length one-fifth of an inch.

May be distinguished from nigrifrons 8. and nigripes 8. by
the intermediate angle of the anterior band pointing forward,

disposition of the lines of the clypeus. It is much larger than
O. latebrosus Fabr., from the female of which it differs consider-

observed any trait which can justify the separation of it from the
Fabrician type.

Var. a.—Elevated lines of the clypeus obsolete or entirely want-
ing.

Var. g.—Anterior elevated line of the head obsolete.

Var. y.—Head bidentate before.

Var. §.—Posterior elevated line of the head interrupted in the

middle.

COPRIS Fabr.

1. C. coLontcaA.—Thorax somewhat retuse ; head with a short
elevation between the eyes.

Inhabits Mexico. .

Body black ; head a little rugose, with a 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 striz ;
interstitial spaces convex.

Length nine-tenths of an inch.

Resembles C. carolina Fab., buttis not so robust, and the tho-
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 Nicanor ? as figured by Drury i. pl. 36,
fig. 1.

2. C. rxcertTA.—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, lmpunc-
tured..-

Length nearly seyen-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

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 cami fot Fabr.,
or even as the triangular’s nob., from both of which it is emi-
nently distinguished by the Gee denticulations. |

4. C. procrpuaA.—Thorax three-horned ; head two-horned.

Inhabits 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 impunc-
tured ; elytra with impressed, punctured striz ; interstitial spaces
convex, impunctured.

Var. «. Highly polished.

Length more than three-fifths of an inch.

The armature of the thorax is very similar to that of C. Juna-
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.

Inhabits Mexico.

Head widely emarginate before, punctured; disk convex im-
punctured: antennz cinereous at tip; palpi honey-yellow : thorax
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 striz, 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 Jateral

vitta: with slender punctured striz; interstitial lines flat, im-
punctured.

Length over three-twentieths of an inch.

Very closely allied to the ‘nguinatus 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.

PSAMMODIUS Gyll.

P. rvrerruprus.—Thorax with three lateral, transverse undu-
lations.

Inhabits Indiana.

Body dark chestnut, punctured : head deeply and somewhat
acutely emarginated ; with very numerous raised points: thorax
with about three, lateral, transverse, but little impressed grooves,

In the sw/cicollis Ill., the thoracic grooves are not interrupted on
the back; it is also smaller than the present species.

ODONT.AAUS Meg.

O. MUscULUS.—Small, brown, with short hairs; elytra with
punctured striz.

Inhabits Indiana.

Body small, light chestnut brown, darker before, with very
numerous short hairs, punctured: head, between the eyes, with a
hardly elevated, arcuated line, above which is a transverse
indentation, then a hardly perceptible raised line: labrum
emarginate; mandibles concave above, convex beneath, regularly
arcuated, exterior edge entire: clypeus not trilobate at tip, entire:
antennze yellowish at tip: thorax convex, laterally a little dilated

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 Oliv. than the cephus Oliv.

TROX Fabr.

1. T. atrernatus.—Elytra with cinereous, elevated lines
interrupted by black spots.

Inhabits United States.

Body black, or black slightly tinged with brown: head bituber-

punctured ; posterior angles obtusely dentate: scutel, posterior
margin Cinereous: elytra striate with dilated punctures; alternate
interstitial lines more elevated, cinereous, interrupted by black spots.

Length over half an inch.

This species is readily known by the cinereous and black
alternation of the more elevated interstitial spaces. A variety

[Vol. I.

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 an individual taken near New Orleans.

A. label, attached to a specimen in my cabinet, states that it
cannot be the crenatus Oliv., with which I am now unacquainted.

[Belongs to Omorgus, and was previously described as 7.

T. globosus Melsh. Catal.

Body blackish-bronze, punctured : head entire, unarmed ; thorax
with an impressed line on the anterior lateral submargin: elytra
with oblong, deeply impressed, rather distant punctures; posterior
declivity with four or five elevated, converging lines, the two exte-
rior ones continued towards the humerus ; exterior edge with numer-
ous, approximate teeth : posterior tibize much dilated and compressed.

Length about one-fifth of an inch.

[Belongs to Acanthocerus.—LECc. ]

3. T. sPLENDIDUS.—Dark brassy; elytra with series of punc-
tures, and on the posterior declivity with elevated lines.

Inhabits United States.

T. splendidus Melsh. Catal.

Body rather short, oval, polished, dark bronze ; punctured : head
unarmed, entire: thorax with an impressed line on the anterior
lateral submargin : elytra with regular series of rather long, deeply
impressed, approximate punctures; on the posterior declivity four
or five elevated, converging lines, the exterior one extending
towards the humerus; posterior tibize much dilated and impressed.

Length nearly one-fifth of an inch.

Readily distinguishable from the preceding by the more approxi-
mate punctures of the elytra, and the simplicity of the lateral
edge. They both exhibit a remarkable difference, in their smooth
surface, from the greater number of the species of this genus.

MELOLONTHA F abr.

M. 1nreGrA.—Reddish-brown, hairy ; clypeus entire.

Inhabits Mexico. [181 ]

Body reddish-brown, hairy on every part: head with rather
large dense punctures; tip of the clypeus obtusely rounded ; thorax
with the hair equal, reflected : scutel with rather short hair: ely-
tra destitute of elevated lines; hair longer near the base : post-
pectus with long hair: feet with sparse hair.

Length less than three-fourths of an inch.

Distinguishable from all the other known North American
species by its rounded clypeus combined with its universal hairy
vesture and magnitude.

ANOMALA Meg.

1. A. GemMEeLLA.—Yellowish-white, varied with blackish, ely-
tra with geminate striz.

Inhabits Mexico.

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
dot on the middle of the lateral submargin : scutel piceous: ely-
tra with rather distant, large and blackish punctures; three
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.

Length half an inch.

In some respects resembles A. wnifasciatus nob., but it is
larger, with a shorter head, and is very different by other
characters.

2. A. crncTA.—Bluish-green, elytra pale brownish.

Inhabits Mexico. [182]

Head cupreous, punctured: thorax slightly punctured, bluish-
green: scutel bluish-green, punctured: elytra pale brownish, or

regular punctures near the suture: suture and edge all around
and spot on the humerus blackish-green : ‘antennze and palpi fer-
ruginous.

Length over half an inch.

This insect and the preceding may be only varieties ; never-
theless, having three specimens that are similar to each other, I
may state that it differs from A. gemella nob., in the more ob-
viously punctured thorax, in not having the striz of the elytra
so obviously in pairs, and in the color.

HEGETER Latr.

H. puncratus.—Thorax transverse; elytra punctured, and
with obsolete series of punctures.

Body black, densely punctured: antenne and palpi piceous ;
terminal joint of the maxillary palpi rather large: thorax trans-
verse, convex: elytra irregularly punctured, and with regular
series of punctures: feet piceous.

and indentations and punctures.

Inhabits Mexico.

Body black, oblong-oval; head minutely rugose, with an obtuse
indentation each side: thorax inequal, with [183] elevated obtuse
lines and indentations, and numerous small, elevated dots; pos-
terior angles acute: elytra with many small elevated dots, and
deeply impressed, distant punctures; several elevated, obtuse,
abbreviated lines, of which the largest one is near the middle
and extends to the posterior declivity ; on this declivity are three
large, elevated tubercles; an abbreviated line extends from the
humerus, and a very short basal one is nearest the suture:

Body black, punctured: thorax somewhat longer than broad,
punctures confluent each side and behind; a transverse, sub-
basal, indented band, obsolete in the middle; lateral margin
rounded, the marginal, hardly elevated line being so low on the

Body black, nearly opaque, very minutely punctured: head,
transverse line between the antenne, obsolete: thorax rather
wider than long, greatest width a little before the middle; lateral
edge a slightly elevated line, abruptly a little excurved at the
posterior angle, exhibiting [184] in that part a very small, acute,
lateral projection: elytra smooth to the eye, but on close inspec-
tion minutely and irregularly rugose and punctured ; lateral
margin rounded.

Length over three-fifths of an inch.

Much like B. xqualis, but distinguishable by its almost total
want of polish, the minute prominence of its posterior angle, and
the microscopic roughness of its elytra.

3. B. MAURA.—Elytra with impunctured, obtuse striz.

Inhabits Mexico.

Body black: head punctured, an impressed line between the
antennz: thorax with hardly discernible punctures; wider than
long; posterior angles not rounded ; lateral edge a vertically ele-

grooved, the grooves impunctured, but viewed in a particular
direction they appear obsoletely rugose; interstitial lines convex;
lateral margin rounded and evidently irregularly punctured ; epi-
pleura impunctured ; feet punctured.

Length more than three-fifths of an inch.

Body black, immaculate : head slightly punctured ; an impres-
sed line between the antennz: thorax wider than long; lateral
edge a slightly elevated line, a little excurved at the posterior
angle, which is consequently somewhat acute: elytra with obso-
lete grooves, minutely punctured; lateral margin rounded and
smooth: thighs not obviously punctured. [185]

Length less than three-fifths of an inch.

Resembles the preceding, but differs in the excurvature of the
lateral thoracic edge near the posterior angle, and in the grooves
of the elytra being obsolete.

5. B. cetsa.—Body somewhat elongated ; elytra with traces
of grooves and punctures.

TInhabits Mexico.

Body brownish-black, minutely punctured, somewhat elongated:
head with the impressed line between the antennz obsolete: an-
tennee at tip, and palpi piceous : thorax rather wider than long ;
lateral edge a slightly elevated line, not excurved at the posterior
angles; an obsolete, abbreviated, oblique, impressed line near
the posterior angles ; somewhat attenuated behind ; lateral margin
rounded.

Length more than three-fifths of an inch.

More slender than the maura and obliterata, which have no
appearance of an indentation near the posterior angles of the
thorax.

6. B. mquatis.—Elytra smooth, simple ; thoracic basal angles

rot excurved.

Inhabits Mexico.
Body black, minutely punctured: head with the impressed

line between the antennz, obsolete: thorax broader than long,
broadest in the middle; lateral edge a slightly elevated line, not

appearance of the rudiment of a groove or of striz ; rounded on
the lateral margin.

Length over three-fifths of an inch.

Shorter and more robust than B. celsa nob.; allied [186]
more closely to B. obliterata nob. ; but the elytra of that species
are much more rough, and its antes: thoracic angles are slightly
excurved.

7. B. parvA.—Lateral thoracic edge recliyate ; elytra with
punctured striz.

Inhabits Mexico.

Body black, punctured: head with two obsolete indentations
between the antenne: thorax emarginate before for the recep-

hind, forming an acute posterior angle; greatest breadth rather
before the middle : elytra with large punctures in regular series ;
interstitial lines irregularly punctured.

Length nearly three-tenths of an inch.

The smallest species I have yet met with in North America.

Of this genus I have described sixteen North American
species, each of which has only the three ultimate joints of the
antennz moniliform ; whereas in all the exotic species of my col-
lection, nine in number, the four ultimate joints are moniliform.

anterior tip of the clypeus is not so prominently reflected, and
the contraction towards the Junction of the thorax and abdomen
is more obtuse.

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.
émpressa 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, certainly a division of the present,
ander the name of Corphyra.

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, | 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 eata-
logue. I introduce the description for the purpose of preserving
the Fabrician name for a species not commonly known.

MORDELLA Latr.

1. M. nmaris.—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.

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 MJ. 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 antenne.

Length three-twentieths of an inch.

P. poLtirA.—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. I.

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, which 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, &c.

The species is rare. [193]

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. ntl

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.

TETRAOPES Schonh.

T. rorNator 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, but
as they are unaccompanied with descriptions, the above will of
course, take precedence.

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.

OF NATURAL HISTORY. 669

Body pale yellowish: antennz 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 Hlig., 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 tibia black.

Length less than one-fifth of an inch.

Resembles the A. collaris Mlig., (zanthomelas 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.

EROTYLUS Fab.

E. 4-puncratus.—Testaceous, beneath black: thorax with
four black dots: elytra trifasciate with black.

Inhabits Missouri.

Erotylus 4-punctatus ? Oliv. Enc. Meth.

middle, dilated on the suture, and a terminal, longitudinally ob-
long spot, black ; edge black: beneath black: pectus each side,
and a series of five spots on each side of the venter, testaccous.

Length three-tenths of an inch.

This insect I believe to be the #. 4-punctata Oliv. and as it
is but little known, I describe it more particularly to fix the spe-
cles.

thorax sanguineous, immaculate: elytra with [202] very dis-
tinct series of well impressed punctures: pectus and head beneath
sanguineous.

Length nearly two-fifths of an inch.

Much larger than Z. 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
thorax, more profoundly punctured elytral striae, and black post
pectus and venter.

I have specimens in my collection from remote parts of North
America. Dr. Harris sent it to me from Massachusetts, and Dr.
Melsheimer from near Maryland. I have found it in the N orth
West Territory, Pennsylvania, Indiana, Missouri, Florida, and
varieties a and Z, in Mexico. The name is taken from Melshei-
mer’s Catalogue.

2. C. DenTIPES Fabr.—Is common in Mexico, and I formerly
obtained an individual in the North West Territory.

3. C. cacti Fabr.—This species occurs abundantly in Mexico ;
it certainly resembles very closely the stigma [203] nob., so
common in this country, and the renipustulata Mill., of Europe ;
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 oval,
whilst that of the stigma is orbicular.

SCYMNUS Herbst. (COCCINELLA F.)

S. TERMINATUS.—Black ; elytra, at tip yellowish.

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—Antennz 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: tibiae 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 antennae, viz., Zarca
and Perga Leach ; but both have clavate antennz and in many
respects are at variance 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. DORSALIS.—Black ; hypostoma, a base of the tergum and
feet whitish.

Inhabits Indiana.

¢ © 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-

cous: tergum pale yellowish on the basal disk, blackish brown
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. scureLLata.—Fulvous; head and thorax, excepting
the humerus and scutel, blackish.

Inhabits United States.

_ 9. 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. cancANEA.—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 : antennz 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: tibize destitute of a spine in
their middle.

1835. ] 43

674 BOSTON JOURNAL

Obs. The name of Cryptus, applied by Jurine to one of his
genera, has been previously appropriated by Fabricius to a genus
of Ichneumonides, 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 antenne. It may be thus divided, with modified

characters. ;

Hytoroma Latr.—Radial cellule appendiculated : four poste-
rior tibiz with a spine on their middle.
Hl. rose F.

ATOMACERA nob.—Radial cellule simple ; tibize destitute of a
spine on their middle.

Oryptus Jurine (by error.)—Antennz of the male biparted :
tibize destitute of a spine on their middle.
C. furcata F.C. Klugii, Leach, Xe.

1. A. peBinis.—Black ; tibia whitish.

Inhabits Indiana.

% Body black, polished : antennee, cilie 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: tibiz, anterior pair dull pale yellowish.

Length three-twentieths of an inch.

2. A. CELLULARIS.—Black ; abdomen rufous.

Inhabits Indiana.

2 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, coxee, trochanters and small base of the tibie, whitish ;
anterior pair of tibie dull whitish.

Length less than one-fourth of an inch.

Much smaller than Hylotoma abdominalis Leach, which it
probably resembles.

[Vol. I.

OF NATURAL HISTORY. 675

THULEA Say.

Artificial Character.—Antenne six-jointed ; last joint clavate.
Radial cellule one. Cubital cellules three.

Natural Character.—The antenne are rather short, decidedly
clavate ; 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 Sth, 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 antennz, 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 Zara 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-
lules.

T. nrGRA.—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.

It resembles the ma/acus, and requires the additional deserip-

The remarkable resemblance which exists between the present

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 coxe, give it a little the air
of a Fenus, but the numerously jointed antenne place it in this
family. [237]

OPHION Fabr.

1. @. puraATUS.—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 bilineatus nob., may be
distinguished from this species by haying 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.

large cubital cellule.

Inhabits Indiana.

Body dull honey-yellow: head bright yellow: antennz, mouth
and stemmata honey-yellow : eyes blackish: wings, first cubital
cellule beyond its middle with a longitudinally oval glabrous
space, but destitute of any opake spot: metathorax transversely
wrinkled near the petiole of the abdomen.

Much like purgatus nob., with a similar glabrous spot in the
cubital cellule, but this spot is destitute of any appearance of
the opake coriaceous spots which distinguish that species.

3. O. MuNDUS.—Black ; antennee, posterior tibie and tarsi
yellow.

Inhabits Indiana.

3% Body black : head with the front, nasus and anterior orbits
greenish-yellow: antennz fulvous yellow; three or four basal
joints above black; the first joint beneath greenish-yellow : trunk
with rather dense, short hairs: wings purple-black : abdomen
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 tibise yellowish : [248] posterior pair
with the tibie, 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.

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
nervure, which are always black in the populator.

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. Ifthe genera throughout this order, are not to be
divided as in the Tenthredinetx, | 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

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
game 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 ee
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 antenne 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.

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.

silvery hairs, particularly on the head, on the anterior segment
of the thorax and on the metathorax: thorax with four slight,
im»ressed lines, and numerous confluent punctures : metathorax
reticulate with punctures, and with a slight groove from the base
nearly to the middle: wings dark purplish-fuliginous ; radial cel-
_lule rounded at tip, not truncate; third cubital cellule [296]

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 valvwlus 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.

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 eqyal-
ity of the edge. This arrangement gives the surface an alternate
appearance.

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
rug: pleure 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 tibia 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; I have, however, in this
instance, been guided by the characters laid down by Latreille
in the Régne Animale (first Edition).

3. 8. CONFLUENTA nob. Western Quarterly Reporter.—I think
it highly probable that Drury’s fig. 5, pl. 44, vol. it 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 radula ¥. 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 [865] Sphea plumi-
pes Drury. If this be correct, Drury has the priority, and the
name and synonyms, will stand thus :

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.

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

the middle: wings slightly dusky ; a darker band at tip; by an
obliquely transmitted light, opalescent, varying to purplish, and
at tip, in the darker portion, tinged with green; recurrent ner-
vures entering the second cubital cellule very near to each other,
but little more than their own width apart: metathorax, poste-

1. T. porirus.—Black ; very highly polished: without any
silvery reflection ; thorax and scutel with a slightly impressed,
longitudinal line: wings black-purple, almost opake : abdomen
rather less slender at base than that of 7. figulus F., but the ba-
sal joint is rather abruptly slender on its basal half; this segment
has an abbreviated, impressed, longitudinal line before its tip ;
second segment with a similar line before its middle: on the
head and stethidium are very numerous, small punctures, but
none on the abdomen: posterior tarsi white, first joint at base,
and pulvilli blackish.

Inhabits Indiana.

Length nine-tenths of an inch.

Judging by memory, as I have not his work here, this is prob-
ably the albitarsa Beauvyois, but although it agrees with the short
description of Fabricius, yet I greatly doubt if it is the albitarsa
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 [$74] in the insect productions,
I give a new name to this species.

2. T. chAvATus.—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.

{Vol. I.

OF NATURAL HISTORY. 757

Var. a. 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
nigra cyaneo parum nitide,” neither does it agree with “ Pedes
nigri 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 antenne,
divaricating above the antenne into two carine : antenne 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.

scale honey-yellow : wings hyaline : seutel 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-

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 tibie have a white line.

This species resembles the O. trispinosus Fabr., but that inseet
may be distinguished by the dilated figure of the spot on the basal
segment of the tergum and by the tibize being entirely honey-
yellow.

3. O. Larus.—Line on the collar, on the scuteland five lateral
spots on the tergum yellow.

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 tibize 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.

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.

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.

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

STIGMUS Jur. Latr.

1. S. PARALLELUS.—This species resembles the fraternus nob.
but it may be distinguished by the following comparative char-
acters. he 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 /raternus, the latter
ig more oblique.

The size is much the same.

Inhabits Mexico.

The Stiymus fraternus, is not uncommon in Indiana, and as in
the present species, the hypostoma of the male is somewhat sil-
very.

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]

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 isbehind the scutel.

This is much like the guadridens 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.

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

1837.] 49

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] Se. Nat. tom. 4,
p. 335,) 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 lien de soupconner que ces insectes sont iden-
tique ou peu differens,” from his P. lecheguana.

774 BOSTON JOURNAL

Length less than one-fourth of an inch.

A very common species. I have found their nests in [396]
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-
hblage are the young of all ages to the perfect insect.

The male varies in having the tibize and tarsi yellowish-white,
with more or less of green on the middle of the posterior tibia.

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.

it, as well as with Anthophora lagopoda Fabr., if I may judge
by the similarity of the anterior feet, though it certainly ap-
proaches Steles in the paucity of ventral hair. The maxillary

M. BREVIS.—Black ; not remarkably hairy; anterior tarsi
simple ; abdomen short.

Inhabits Indiana.

& Body black, somewhat polished: head densely covered
with long, yellowish hairs in front: thorax with whitish hair,
sometimes tinged with yellowish, and not concealing the surface :
wings a little fuliginous, tinged with violaceous: venter not, or
hardly longer than broad: tergum with small, dense punctures,
and a narrow, white band on each segment; anal segment trans-
versely concave, at its tip emarginate, in ile smite and on each
side, [408] the edge has several small denticulations : anterior
tarsi simple : tarsi piceous at their tips.

Length less than two-fifths of an inch.

Q A little larger than the male; with very little hair on the
front ; abdomen short conic-oval ; venter hairy.

Length two-fifths of an inch.

The male of this species closely resembles that of pugnatus,
so much so, that it might readily be considered as the same ; but
the anterior tarsi are not dilated, and the abdomen, although
similarly terminated, is remarkably shorter.

M. puanatus.—Black ; anterior tarsi dilated in the male,
with the first joint prolonged at its anterior angle beyond the tip
of the second joint.

Inhabits Indiana.

%, Body black, not densely hairy: head densely covered with
long whitish hairs in front: thorax with whitish hair not con-
cealing the surface: wings fuliginous, tinged with violaceous ;
venter longer than broad: tergum with small, dense punctures ;
and a narrow white band on each segment; anal segment trans-
versely concave, at its tip emarginate in the middle, and on each
side the edge has several small denticulations: anterior tarsi
whitish, dilated, and ciliated; anterior tip of the basal joint pro-
longed a little beyond the tip of the second joint, and its whole
leneth excavated before; anterior tip of the second joint also
prolonged almost to the tip of the third joint; fourth joint not
dilated : anterior tibie with dilated crowded punctures : anterior
coxee, each with a prominent, black spine: intermediate and
posterior tarsi piceous at tip.

TR4 BOSTON JOURNAL

Length over two-fifths to nearly half an inch.

? 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 /atimanus, or pollicaris nob., and has a somewhat different
habit.

ANTHOPHORA Latr.

1. A. ABruPTA.—% 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 fulyous 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. FRONTATA.—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-
tenn 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.

a yellow oval spot at base and a 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-scale blackish: wings with a slight dusky tint; nervures
black, exterior recurrent nervure entering the outer cubital
cellule 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 3 about two-fifths; 9 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 cylindrical 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 ebserved 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 Siiqguaria. 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 Cenfris, 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. 48, of vol.i,
for Bombus virgineus Linn., leads me to suppose that he had
this species also in view in that description. Butas that descrip.
tion in the Syst. Piez. p. 846, 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 XY. 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 antennee; thorax hairy.

Inhabits United States.

© Body black, tinged with purplish: head with close set,

‘ [Vol. I.

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 middle:
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 nasuy. 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 : antennz with an anterior white line on the radical joint :
gene with a few gray hairs: wings, first recurrent nervure 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 ? 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,

i , nsiderable por-
~ however, is so much elongated as to conceal a co I

788 BOSTON JOURNAL

tion of the next segment. The color is a much deeper yellow
than that of fervida.

2. B. EpHIppratus.—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 eolor of the pleura.

Length less than half an inch.

3. B. rernartus.—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 ; antennz, 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 cilize of the
edge sparse.

Length less than one-fourth of an inch.

It is somewhat smaller, and less robust than the rujficrus Latr.
of which the posterior tibiz are densely ciliated. I am indebted
to Dr. Klug for a specimen of the ruficrus: and it is very differ-

ent from the amalthea and spinipes Fabr. My specimens are

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 T'rigonia of Conchology, but as the pronunciation
differs it can remain.

2. T. LiGATA.—O Blackish ; abdominal segments margined
with ochreous.

Inhabits Mexico.

Body brownish-black, hairy; antennz 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 tibiee 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 Mllig., 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.
