Head closely and confluently punctured and with sparse whitish 

 scaling, vertex convex, forehead almost plane ; anteocular furrows 

 absent. Rostrum not incised at base, as long as head and pro- 

 thorax, very little curved, dilated towards apex. Upper surface 

 with five smooth narrow carinse of about equal height; lateral 

 sulci distinct, the upper pair longer and uniting at base ; scrobes 

 lateral, shallow and curved ; inferior basal furrow absent.

 broadest before middle, dorsal anterior margin truncate, ocular 

 lobes feeble. Upper surface convex, closely set with low rounded 

 granules, leaving a distinct central f uitow containing no carina ; 

 granules bare, with depressed pale setse, the interstices with greyish

 Elytra narrowly ovate, broader in $ and subacuminate towards 

 apex, shoulders sloping, sides rounded, broadest before middle, 

 apical processes absent. Upper surface convex, with regular 

 shallow stride containing rows of deep closely- set puncttures ; the 

 intervals evenly raised, slightly convex and quite smooth on disk, 

 but with faint traces of gi'anulation laterally ; each interval with 

 a row of depressed white setfe ; the whole surface with moderately 

 dense small white scaling, which is more or less denuded on
