middle; median lobe feebly produced, disc feebly flattened in

 sides of base, closely set and setigerous. Elytra(16 x 9*5 mm.) 

 evenly rounded on sides, strongly declivous; base rather deeply 

 emarginate, shoulders thickened, outturned and prominent; apex 

 mucronate; foveo-striate, fovese almost quadrilateral, separated 

 by rather low transverse ridges; interstices slightly wavy in 

 course, finely setigero-granulate, sutural interstice only prominent 

 at base; second, fourth, and sixth in single series, somewhat 

 irregular; third, fifth, and seventh in double series; sides longi-

 rounded, overlapping. Penis narrowed towards apex, which is 

 bulbous. Postanal process of apical tergite strongl}^ bearded. 

 Legs moderately long, clothed with black setse and rather stout
