 Segnipes of Smith. Head twice as high as long, tapering very rai)idly with 

 arcuate sides, delicately and transversely striate; eye circular, situated 

 slightly behind the base of the beak, nnd removed from the front margin of 

 the prothorax l)y its own diameter; front of licad desciaiding rapidly above 

 and so forming a decided angle with tlie lienk, which is moderately stout, a 

 little shorter than tlie doi'smii of the protlioi'ax, neurly straiglit, equal on 

 the basal, tapering slightly on the apical li.ilf Tliorax considerably higher 

 than long, hardly tai)ering, longest above by reason of the arcuation of the 

 body, delicately and closely punctate. Elytra about twdce as long as

 much as in the group Segnipesof Smith. The head is hut little higher tiian 

 long, subconical, with scarcel}^ arcuate sides, smooth or with exceedingly 

 fine faint transverse striation; eyes large, circular, situated as far forward 

 as possible, and separated from the front margin of the prothorax by more 

 than half their own diameter; rostrum moderately stout, as long as hem I 

 and prothorax together, porrect, gently arcuate, especially on apical half, 

 e(jual or scarcely enlarging apically. Prothorax a third higher tlian long, 

 tapering but little, and with hardly any fullness, nearly smooth or very
