470 Mr. Kirby's Description ofseveralnew Species of Insects 



sed revera deflexa est liorum segmenlorum pars media. Ex 

 fundo cavitatis laminae dua.-, latae, conipressa?, obcuneata?, 

 apice rotundatae, Itevissima?, glaberriina;, nitidte eniergunt, et 

 postice utrinque in margine ipso circuli setarum rigidissinia- 

 runi fasciculi, vel potiiis pectines duo. Basi late cxcavatus est 

 venter. 

 Var. Sexus alter: mandibulis trigonis obscuris, rugosis setosis, 

 acutis, thorace vix impresso, ventre integro: cavitate nulla. 

 I know no insect amongst the Citrculioniche (except one of the 

 same tribe wiih 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- 

 nae, and pecten have no parallel that I am aware of in the insect 

 world. 'J'hese 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.

Stknocorus Fabr. 



pimctatus. 22. St. piceus, thorace spinoso, ely tris excavato-punc-
