 slightly rugulose ; eyes convex, prominent, deeply set in orbits at 

 base ; orbits not protuberant behind eyes. Antenna* filiform, long, 

 compressed, thicker towards apex. Prothorax transverse (1-8 x 2-1

 rounded from apex to base ; anterior angles obtuse, hardly 

 advanced ; basal angle rounded, not marked ; lateral bordei- 

 narrow, even ; median line very lightly impressed ; two short, 

 nariow oblong fovefe on each side of base near basal angles ; 

 posterior marginal setigerous puncture placed a little l^efore the 

 base at extremity of marginal channel. Elytra oblong, truncate 

 on base, very little wider than prothorax (3-8 x 2-3 mm.), 

 cjnvex, strongly declivous to apex ; sides subparallel in middle, 

 rounded to base ; shoulders widely rounded ; apical curve short, 

 hardly sinuate on each side ; four inner stria^ strong, entire,

 sixth and seventh wanting (seventh indicated on apical extremity), 

 eighth strongly impressed ; four inner interstices convex, fifth 

 flat ; lateral interstice punctate on basal and apical third ; lateral 

 border narrow ; basal border narrow, curved on posterioi- 

 margin ; marginal channel narrow. Prosternum narrowed on 

 each side of base, basal border oljsolete ; episterna strongly
