compressa. Femora modice incrassata; tihice recto, corbulia 

 posticis cavernosia ; unguiculi connati. Processus intercoxalis 

 antice angulatus. 



This genus has more the habit of some of the species of Scio- 

 hius than of Episomtis, to which, on account of its cavernous cor- 

 bels and connate claws, it is most allied. 



Cychrotonus viduatus. C. ovalis, niger, subnitidus, fere glabratus; 

 capite inter oculos sulcato ; rostro fortiter tricarinato ; prothorace' 

 crebre punctate, punctis nonnullis squama alba repletis ; elytris pro- 

 funde sat confertim fortiter punctatis, interstitiis subtibssime punctu- 

 latis squamis albis remote adspersis ; corpore infra pedibusque sparse 

 albo-squamosis. Long. 4 Hn. (rost. incl.).

 to Lacordaire, may be thus tabulated : —

Zyrcosa, Pasc. 

 Prothorax not produced. 



Elytra broader at the base than the prothorax. 



Platyomicus, Thorns. 

 Elytra not broader at the base than the prothorax. 

 Scrobes at the apex of the rostrum nearly contiguous. 



SpitapJiocerus,Thom8. 

 Scrobes widely apart at the apex. 



Intercoxal process gradually narrower and forming an 

 angle anteriorly. 

 Elytra at the base projecting on the prothorax. 

 Scrobes terminating before the eye. 



JEpisomus, Schon. 

 Scrobes terminating beneath the eye. 



Antinia, n. g. 

 Elytra truncate at the base. 



Scrobes terminating beneath the eye. 



Cychrotonus, n. g. 

 Scrobes terminating before the eyes. 



Eostrum as broad as the head. Simallus, Pasc. 

 Eostrum narrower than the head. 



Demenica, n. g.
