470 Mr. Kinsy’s Description of several new Species of Insects — 
sed revera deflexa est horum segmentorum pars media. Ex 
fundo cavitatis lamine due, late, compresse, obcuneatæ, 
apice rotundatæ, lævissimæ, glaberrimæ, nitidæ emergunt, et 
postice utrinque in margine ipso circuli setarum rigidissima-

Var. Sexus alter: mandibulis trigonis obscuris, rugosis setosis, 
acutis, thorace vix impresso, ventre integro: cavitate nulla. 
I know no insect amongst the Curculionide (except one of the 
same tribe with this in Mr. MacLeay's cabinet with an anal for- 
ceps, something like that of an earwig,) that is so wonderfully 
formed as the species here described. The ventral cavity, lami- 
nee, and pecten have no parallel that I am aware of in the insect 
world. These organs are probably for sexual purposes, since the 
other sex, if I am not mistaken in supposing the variety I have 
described merely sexual, is without them.

STENOCORUS Fabr. 
punctatus. 22. St. piceus, thorace spinoso, elytris excavato-punc-

Long. corp. lin. 14. 
Corpus lineare, subdepressum, piceum, nitidum, subtus piloso- 
incanum. Caput subinclinatum, subtus transverse rugosum : 
gula in medio levissima, supra subpilosum postice rugosum, 
inter antennas canaliculatum. Labrum transversum: disco de- 
presso. Labium bilobum: lobis divaricatis pilosis. Mandi- 
bule incurvæ, acute, supra rugose. Mazille aperte: lobo
