One of tlie most distinct species of the genus, on account of the 

 outline of the elytra.

 moso, eristis dorsalibus lateralibusque tuberculis conicis, npice ple- 

 rumque sctis duabus coronatis, munitis ; elytris ovatis, dorso esqun-

The male is probably narrower, or with parallel elytra, as in its 

 congeners. This species is well differentiated by the small but 

 prominent tubercles on the crests and sides of the prothorax, the 

 latter appearing as if crenate or serrate. The tubercles on tlie 

 elytra in the species of this genus can only be depended on ap- 

 proximately ; occasionally one side has one more than the other. 



DiALEPTOPUS GRANULATUS. D. $ oblongo-ovalis, niger, esquamo- 

 sus, setulis tenuissirais ubique adspersus ; rostro latitudine vix lon- 

 giore, supra scrobes elevato ; antennis piceis, breviusculis, clava brevi ; 

 prothorace haud cristate, apice valde producto, dorso granulato, 

 utrinque angulatim dilatato, in medio lineatim longitudinaliter sulcato, 

 lateribus infra vage tuberculato ; elytris ovatis, supra versus basin

 exteriore sex, constitutis, apice sat late rotundatis, ad sutuiam sub-
