partem oculorum insertum ; ocuUs intus emarginatis, supra 



sulco distincto plenimque marginatis ; antennis filiformibus 



aut subfiliformibiis; mento quadrato-emarginato. Thorax mar- 



ginatiis, transversiis. Ehjlra thorace paidlo aut vix latiora, 



confuse aut seriatim punctata. Pedes robust! ; femnr'ibus 



interdum incrassatis, plerumque muticis, rarius dente acuto 



armatis ; unguicutis appendiculatis. Prosternum planum, 



utrinque ab episterno antico sulco suturali separatum. 



The Asiatic species of Coh/spo'nhs, so far as I at present know 



them, have the punctures on their elytra arranged in more or less 



regular longitudinal rows, whilst in many of the American species 



they are placed without order on the surface. 



I. Anterior and hinder pairs of thighs armed beneath with a 

 short acute tooth ; intermediate pair simple.

Head distantly punctured ; epistome broadly semiovate, not 

 separated at its apex from the face, anterior border broadly con- 

 cave-emarginate ; antennae three-fourths the length of the body, 

 six or seven lower joints fulvous, the rest fuscous. Thorax 

 twice as broad as long, sides nearly straight and parallel behind 

 the middle, thence rounded and converging to the apex ; upper 

 surface finely and distinctly but not very closely punctured. 

 Elytra oblong, parallel, convex, very indistinctly excavated below 

 the basilar space, coarsely punctured, the punctures irregularly 

 arranged in double longitudinal rows, which contract near the 

 suture and on the outer disk, and become single, the two nearest 

 the suture very regular, each formed of a single series of. 

 regularly-placed punctures ; the interspaces towards the apex of 

 the elytron thick"ned, convex and more or less costate j on the
