as longas the third: éhorax with numerous, distant pune-
tures; elytra immaculate, the striz distinct ; apicial mar-
gin obsoletely rufous; beneath black, with prostrate hair ;
feet dullrufous: posterior thighs somewhat dilated, beneath
blackish with a tooth near the tip & about too small ones
nearer the tip; abdomen dullrufous, immaculate.

dot: posterior éhighs witha spine, beyond which are two
smaller spines.

Length nearly three twentieths of an inch.

*Tam greatly indebted to this distinguished naturalist for his able work the
“Dispositio. Methodica Curculionidum’’ as well! as fora knowledge of several
unpublished genera of this family; my thanks are also due to Germar who hae
kindly furnished me with his’Colcopterorum species novae aut minus copnitaa”
descriptionibus ilustratae”, in which many new gencra are instituted.

1. R. collaris Faby. The three ultimate joints of the
antennae are elongated, differing in this respect from other
species of the genus, it has been separated under the
generic name of Sapindus. | }

_ The species varies so much in colour as to have given
Frise to several specific names; viz.

_—..— nigripes, Melsh. quercus. Knoch in Melsh Catal.

—,,— ruficolis, Germar Sp. Nov. p. 188.

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

‘2, R. hirtus, Fabr. |

R. aeneuvs? Bohemann. : |
- Doubts have been expressed of our insect being the
hirtus of Fabr., but it agrees better with the description
than any. It is also,as Fabricius says, of the stature &
magnitude of ht. pubescens.

3. R. aeratus, Brassy, antennae, rostrum & beneath obse-
ure bluish.

Inhab. Pennsylvania.

- Curculio aeratus, Knoch in Melsh. Catalogue.

Body brassy, punctured : rostrum very slightly dilating
towards the tip, with an impressed line above, from the
base to the middle: front with small punctures: thorax
with dense punctures: elytra with a transverse, dilated but
but not profound, common indentation 5 with striae of tra
nsverse, large punctures: beneath blackish blue.

Length nearly one tenth of an inch.

‘this is the smallest North American species yet known.
’ Thave found it on the Oak in June.

enus PTEROCOLUS, Sch.

Antennae 11-jointed, not geniculate; basal joint not
much elongated ; eighth joint transverse linear; 9th. and
10th. transverse subquadrate, dilated, & with the ultimate
semioval! one, remote, perfoliated, forming an oblong oval
club: rostrum dilated at tip: head rather long behind the
eyes, neck not contracted: scutel transverse subquadrate:
elytra somewhat abbreviated; each rounded at tip, depres-
sed above: podex and part of the back, naked : feet robust:
thighs unarmed, dilated ; tibiae unarmed, ‘ciliate densely |
on the exterior edge with very short spines, and with small
spines around the edge of the tip: body rounded.

This genus differs from Rynchites by the rounded form
of the body; the shorter and depressed elytra, more divar-

G

icate at their tips; the rostrum is shorter and more con-
tracted in the middle, and the origin of the antennae is _
nearer the middle or rather the base of the rostrum; the
tibiae are ciliated with short spines &c.

1. L. marginatus, Black, covered with minute cinereous hairs; th¢rax im-
pressed ; elytra, region of the scutel and middle of the base indented.

Tnhab. U.S.

Body black, covered with short minute robust recurved hairs, punctured ;
antennae rufous, club dusky ; thorax a little convex each side, behindthe mid-
dle of the side rectilinear, a little contracted before, with an indeatéd line
above, more profound, near the base ; with dilated, confluent, slightlyimpress-
ed punctures not deeply sinuated at base, with regular series of punctures : ely-
tra region of the scutel indented subacute: abdomen dull fulvous behind.

Length from the origin of the rostrum nearly seven-twentieths pf an inch:

The hair detains a ferruginous powder. It is found on the lower Missouri.
It also occurs in the Atlantic states. With my first description of this species I
gave it the name of impressus, but in the Curcul. dispos. methed. Schoenherr
quotes the same name for a very different and large species of S. America
from Sahlberg.

2. L, concavus, Base of the thorax and of the elytra with a common dilated
indentation.

Inhap. Indiana.

Thorax convex each side, much contracted before, with very small punctures;
dorsal indentation obsolete near the anterior margin and in the middle, profound
at base: elytra with regular punctured striae, not rugose; base with a dilated
commor deep indentation equalling that of the thorax, and another smaller in-
dentation on the middle of the base : thighs unarmed.

Leng‘h over halfan inch.

Comnon, and is the largest species I have met with in this country. The
hair of the body detains a yellowish ferruginous dust which often gives the
whole insect that colour. It is smaller than the angustatus F. the thorax is
much nore convex each side, the elytra are less abruptly contracted each side
at base, &c. :

3. L. lateralis, Thorax laterally cinereous; elytra with a transverse basal
groove.

Inhao. Arkansaw. .

Bod: rather slender ; head punctured between the eyes: rostrum but little ar-
quated, punctured between the eyes, short - thorax with rather large profound
distant punctures on each side, ¢inereous; a-dorsal indented line; sides recti-
linear on the posterior three-fourths, and rather suddenly contracted on the an-
terior hurth : elytra with regular series of punctures ; somewhat indented about
the scuel ; basal margin with a groove, basal edge much arquated.

Length seven-twentieths of an inch. .

4. L.musculus, Thorax indented before and behind the middle and with ra-
ther small punctures.

Inha}. Louisiana.

Bedy black or blackish piceous, with short white hairs: head between the eyes
a littleindented: rostrum slightly arquated, punctures at its lateral base nearly
as large as those of the thorax ; thorax with rather small but dense punctures,
with alarge longitudinal depression on the back, a little impressed and more
obvious before the middle and at the base : elytra with series of punctures which
at tip cre smaller and placed in striae : region of the scutel indented.

Length over seven-twentieths of an inch.

It issma!lerthan L. bardane, F’. not so densely clothed with hairs, the elytral
punctures are more obvious ; the thoracic punctures are a little smaller ; that
species has not the thoracic indentations. It has the rostrum a little longer
and more arquated than in the preceding; the thorax has not such large and pro-
found pinctures, on the side is slightly and regularly curved, not abruptly con-
tracted before, &c.

This species was sent to me by Mr. J. Barabino of New Orleans.

ERIRHINUS, Schoenh.

BE. mucidus, Body black-brown with short prostrate yellowish hairs + rostrum
slender, linear, arquated, punctured, much longer taan the head and thorax :
antennae rufous: elytra with rather wide, impressed, densely punctured striae;

Body dull ferruginous ; rostrum more than half the length of the body; thorax
with three obsolete whitish lines: pleura bilineate, of which one is more distinct:
elytra with double series of punctures, the interstitial lines alternately elevated,
the two inner ones on each with two or three compressed elevations, of which
the posterior one on the inner line is more prominent; posterior declivity paler :
anterior thighs two toothed, the posterior tooth prominent.

Curculio myrmex, Herbst. Natursyst.
In appearance it has a slight resemblance to a Formica:

BALANINUS, Germ. \

1. B. proboscidus, Fabr. (Rynchaeus) Rostrum as long again as the body.
This seems to be Curculio Daviesii, Swederus in Transactions of the Stockholm
Society, 1787, and it is probable that the latter name is prior to that of Fabr.

2. B. nasicus, Rostrum not so long as the body or hardly longer, not thicker
at base, but proceeding abruptly from the head, rectilinear to the middle, piceous.

Inhab. Pennsylvania,

It is remarkable by having the rostrum at base hardly thicker than in the
middle, in consequence of whichit appears to proceed abruptly from the head
without any gradation.

It is the Curculio nucum of Melsh. Catalogue.

3. B. rectus, Rostrum rectilinear or very slightly recurved to near the tip
where it curves downward ; antennae very slender.

Inhab. Pennsylvania.
This is distinguishable by the rectilinear or slightly recurved rostrum.

4. B. nasutus, Body robust ; scutel elongated white.

Inhab. Pennsylvania.

This species differs from proboscideus, Ff’. in being more robust and in having
the scutel longer. Schoenherr has proposed the name of rostratus for this insect,
(in litt.)

TYLOMUS, Schoenh.

T. lineaticollis, Say. [Rynchaenus] Journ. Acad. Nat. Sc. Vol. 3, p. 313.

Var. a: much smaller.

Length cxclusive of the rostrum less than one-fifth of an inch.

It differs also considerably in the lineations of the thorax, ard the alternate
elevated, interstitial lines of the elytra are less obvious and not so acutely edg-
ed. Ihave named it provisionally palmicollis.

ORCHESTES, Ilig.
1, O. ephippiatus, Blackish piceous ; elytra each with two yellowish spots.

Inhab. Indiana,

Body blackish, more or less tinged with piceous, densely punctured : baze of

somewhat common spot before the middle and a transverse abbreviated common
band of yellowish hair behind the middle, both on a piceous surface; feet and
antennae rufous,

Length over one-tenth of an inch.

A very distinct species.

panel U.S.

urculio trinotatus,

—::—Pensylvanicus K. t Melsh. Catal.

Body black, covered with rather short, robust, linear, white prostrate hairs:
thorax with the hairs pointing towards the longitudinal middle; at base on each
side is a black dot, scutel black: elytra with obvious striae: interestitial lines flat
and each with about three series ofthe short hairs:

Length three twentieths of an inch.

The covering of white hairs, with the three denuded spots distinguish this
species. I have obtained it in Indiana as well asin Pennsylvania.

2. B. picumnus, Herbst. Natursyst.

Vol. 7, p. 30, pl. 99, f£ 9. This is a common species. The third joint of
the antennae is hardly longer than the fourth. The covering of hairs is more
dense than in the preceding species.

3. B. penicellus Herbst. Naturyst. Vol. 7; p. 29, pl. 99, f 6 F.

Much like the preceding but larger and the third joint of the antennae is as
long again as the fourth. I described it under the name of amictus but I have
little doubt that itis the species described by Herbst. Genus Toxerus Sch. ?
holosericeus Sch. Dej.

4, B. undatus, Black; elytra with two undulations,

Tnhab. Mexico.

Body black: head with small punctures, sparse on the vertex, more dense on
the rostrum: rostrum arquated: thorax a little compressed each side on the an-
terior margin; with rather large confluent lateral punctures and smaller sparse
ones on the disk: elytra with capillary impunctured striae, becoming rather di-
lated at tip; interstitial spaces flat, with numerous transverse lines, a dilated in-
dentation or undulation before the middle, and rather behind the middle, a less
obvious indentation near the tip.

Length over one fifth of an inch. .

Var. A. Body dark brassy polished; undulations of the elytra obsolete.

Length less than three twentieths of an inch.

‘The pectoral groove is very distinct, but the antennae are too robust, and
the club is too obtuse to be placed in the genus Centrinus, and the fusiform club
of Madarus wili not permit a reference to that genus.

5. B. striatus, Interstitial lines hard!y wider than the striae and with a single

series of punctures,

Inhab. U.S

Body black,punctured: rostrum a little prominent at the insertion of the anten —
nae on each side; more or less transversely indented between the eyes: anten-
nae dark piceous inserted beyond the middle of the rostrum; second joint rather
Jong; third not longer than the fourth; club obtuse; thorax subconic with approx-
imate orbicular punctures end a glabrous middie line; basal edge deeply sinuous

[is]

elytra with deep punctured striae; interstitial lines hardly broacer than the
striae and each with a single series of rounded punctures: nal tip naked,densee
ly punctured: pectus slightly indented: anterior feet not very distant.

Length one fifth of an inch.

This isthe true striatus of Melsheimer’s Catalogue ; the following species
which I formerly confounded with it, is different.

6. B. interstitialis, Nob. (Rynchaenus) Journ. Acad. Nat. Sc. 3,p. 314.

Much like the preceding, but the thorax is more rounded, being more abruptly
contracted before & the punctures are much smaller. The interstitial lines ‘are
broader & their punctures have a transverse rugulous appearance.

7. B. transversus, Thorax at the scutel obtusely jobed; scutel transverse.

Inhab. Missouri.

Body black, punctured: head transversely indented between the eyes: an-
tenmae obscure piceous, inserted beyond the middle of the rostrum; third

with close set, almost confluent punctures; third line with more than one see
ries; exterior & posterior edges piceous: dibiae a little tinged with piceous :
anal segment naked, punctured.

Length over one fifth of an inch.

Yn the form ofthe:thorax it resembles interstitialis, Nob. but the punctures
wre much larger, the ‘posterior lobe is more rounded, & the punctures of th
interstitial lines are rounded. :

space behind.

Inhab. U.S.

Curculio elegans, Melsh. Catal.

Body dull piceous, more or less varied with brown or blackish: rostrum
sulcated, carinate, piceous!: antennae sufous: thorax lobed at the eyes ; punc-
tured ; an obsolete, oblique, cinereous line each side proceding to the posterior
angles: elytra with four somewhat elevated, acute lines, the exterior ones

line is interrupted, & the line is aleo depressed or interrupted towards the base ;
thighs two toothed, somewhat annulated with piceous & blackish.

Aength less than one fifth of an inch.

Var. A. Somewhat cinerous.

Var’ B. Paler piceous ; larger.

I have obtained this species in June on Pinus rigida. The body is more ob-
long than that of anaglypticus ; the humerus is less prominent. It occurred in
New Jersey, Florida, & the varieties in Missouri. Canthis be C. aratue, Ger-
mar? His description does not altogether agree with my specimens.

_ 3. C, foveolatus, Black, with large, profound punctures ; elytra with yellow-

thorax with three smali yellowish spots & one before; e/ytra with regular series
of large quadrate punctures ; several small yellowish spots & a large, irregular
one behind : feet unarmed. ;

Length less than one fifth of an inch. |

This insect differs so essentially from the characters of this genus as given
by Schoenherr that it may be separated under the following name & characters
Genus Tyloderma, Antennae rather short & robust, eleven jointed ; rostrum
moderate, rather robust, arquated ; pectus grooved ; postpectus entire; thorax
lobed at the eyes; tarsi spongy beneath: elytra coyering the tip ofthe abdo-
men, ’

From Cryptorhynchus it is distinguished by the number of joints in the
antennae, & in thisrespect it agrees with Lyprus. Tapinotus é& Ulosomus
Sch. but the former has the tarsi compressed & not spongy beneath ; Tapinotus
has the elytra shorter than the abdomen é& in Ulosomus the recipient groove is
extended upon the postpectus. Ihave not seen the insect which forms this
latter genus, but its characters seem to agree better with the above described
than any other. ~

4.C. bisignotus, Elytra with an oblique whitish spot rather before the mid-
dle, Blackish brown: body covered with small scales, which are more erect
Pon the thorax ; chorax extended on the posterior middle at the scutel, & acute:
elytra with about four elevated lines é& intermediate double series of punc,
tures ; an oblique, oval, whitish spot rather before the middle.

the punctures: scufel polished : elytra with regular series“of rather large pune-
tures, the four interstitial lines next the suture, on each, more elevated than
those of the middle.

Length about three tenths of an inch.

Xn comparison with R. venatus, the thorax is much more densely punctured,
and the lateral vittae are rectilinear.

8. R. immunis, Naked; thorax profoundly punctured, excepting on the middle
and each side of the middle.

Body black, punctured: rostrum arquated, compressed, piceous towards the
base; with an impressed, punctured line ; antennae piceous : thorax with dense
punctures, destitute ofobvious elevations : scutel concave, polished : elytra with
series of punctures rather wider or as wide as the interstitial lines, which also
have a series of small punctures ; tip dull piceous : fee¢ rufous, with black incis-
ures,

Length about three tenths of an inch.

In general shape it resembles R. tmmunis, N. but the thorax has not very ob-
vious elevations and is more generally punctured ; the punctures of the ely-
tral series are larger & the interstitial lines have a series of small punctures ;
the feet also are rufous,

10. R. inaequalis, Thorax with numerous discoidal punctures ; elytra with
the punctures in the series remote.

{nhab. U.S.
_ Body black, more or less covered with a dirty brown pigment or crust, pun-

etured ; rostrum moderate, compressed, arquated, with an. impressed line at
base ; thora« with discoidal punctures and from one to three'slight elevations:
elytra with obvious striae, in which are remote’ punctures; interstitial lines
with oblong, longitudinal punctures ; sutural line witha series of small close
set punctures. i

Length nearly one fourth of an inch.

The elytral punctures are remote in the striae, and those of the interstitial
lines are much elongated.

line between the eyes, and another on the middle of the rostrum.

Curculio corticola, Melsh. Catal.

Body deep black, immaculate, punctured ; head, punctures minute and remote
upon the vertex and becoming larger and more dense'towatds the tip of the
Tostrum ; a profoundly indented, dilated line between the eyes; rostrum dila=
ted towards the tip, piceous: thorax with a transverse obtusely indented line
on the anterior sub margin; punctures large separate pt¢found orbicular,minute
upon the anterior margin and confluent upon the posterior and lateral margins ;
middle of the base widely indented and with a carinate line inthe indentation :
elytra profoundly striate, striae with large profound transverse punctures.

Length, base of rostrum to tip of elytra more than three twentieths of an
inch.

A species equally common in Missouri and Pennsylvania. I have observed it
to inhabit in considerable numbers under the loose bark of yellow Pine trees
in October.

2.'C. platalea, Thorax impressed behind ; rostrum punctured ; thorax rather

short.
Inhab. U.S.
ATead punctured, a little indented transversely between the eyes; rostruss

dilated towards the tip, punctured : antennae piceous; thorax with the
punctures not very profound, distant, irregular ; a basal indentation, witha
slight, obtuse carina in the middle of the indentation ; rather short, much rou-
nded on the sides ; elytra, striae with large punctures ; tarsi obscure piceous.

Length nearly one fourth of an inch.

The thorax is proportionally shorter than that of the corticola, the punctures
are less deeply impressed, and the rostrum is not obviously indented longitudi-
nally. It varies in having the tibiae obscure piceous.

DRYOPTHORUS, Schupp.

D. corticalis, Thorax with dilated punctures; elytra with dilated striae.

This is so much like D. lymexylon Fabr. that it is considered the same: but
on comparing with my European specimens, J find it smaller and the punctures
of the head are obsolete, whereas inthe European specimens they are large
andobvious. This is the Curculio corticalis, Payk. of Melsh. Catalogue.
