apex to form the slightly prominent anterior angles, lightly sinuate 

 on each side just before the })ase, thicker but hardly raised on 

 base; a light elongate lateral basal impression extending forward 

 from each juxtabasal sinuosity; median line linear but strongly 

 impressed. Elytra wider than prothorax, elongate-oval (12-5 x 

 6-1 mm.), widest (including border) behind middle, narrowed to 

 base, convex, lightly depressed on each side of suture, strongly 

 declivous to apex ; base lightly emarginate behind peduncle, 

 strongly and abruptly declivous, the declivity impunctate; apical 

 curve wide, apex produced shortly and obtusely beyond lateral 

 border; a strongly raised roundly convex oblique ridge on each 

 elytron above basal declivity, a punctate depression behind this 

 ridge; border narrow near shoulders, becoming very wide and 

 thick posteriorly, reaching peduncle, strongly upturned and 

 rounded at humeral angles; a row of umbilicate punctures along 

 margin, these becoming more widely placed near apex. Ventral 

 segments impunctate. Legs long, light; anterior tibiae with apex

 orbital punctures on each side; eyes deeply set in orbits, depressed; 

 orbits large, equally prominent w^ith and enclosing posterior two- 

 thirds of eyes, projecting abruptly behind from sides of head.
