Light brown, with a shght metalUc sheen ; head broadly and deeply 

 emarginate in the anterior part, and with the angles of the emargi- 

 nation sharp and slightly recurved, genae slightly incised laterally 

 and with also the angles of the incision sharp, that of the genae, 

 however, is sharper than that of the clypeus, the surface is covered 

 with setigerous punctures not closely set, and there is a slight 

 indication of a transverse raised line between the eyes ; anterior 

 part of the head depressed in the centre ; prothorax convex, strongly

 and with the edge of the lateral impression sub-carinate ; it is very 

 slightly attenuate in the anterior part, and the surface is covered 

 with somewhat closely set punctures bearing each a moderately 

 short, sub-flavescent hair curved at tip, the lateral depressions, 

 however, have much shorter hairs, in the central part of the disk 

 there is a longitudinal impressed line reaching from the top of the
