Robust. Black; pubescence white, fine inconspicuous on dorsal 

 surface of elytra, pro thorax dorsally with scattered, sparse scales; on 

 sides of mesothorax and metathorax moderately dense. Beak of male

 pro thorax, slightly curved; basal fifth rather stout, subcylindrical, not 

 expanded laterally at antennal insertion; basal half with sparse punc- 

 tures and scales; apical half smoother, bare. Antennae inserted at 

 basal sixth of beak at distance from eye equal to width of frons; first 

 segment equals next two, second segment shorter than next two, club 

 0.24 by 0.10 mm. Eyes moderately prominent; frons slightly wider 

 than dorsal tip of beak, flat medially. Prothorax at base one-fourth 

 wider than long, middle slightly narrower than base, apex three- 

 fourths as wide as base; sides beyond basal lateral expansion nearly 

 parallel-sided to middle, rounded to constricted apex; in profile dorsal 

 surface nearly flat; punctation 0.03 mm. in diameter, rather shallow, 

 irregularly placed, a large impunctate area laterally at base, inter- 

 spaces from one-fourth as wide to wider than punctures; basal fovea 

 deep, linear, extending about one-half length of prothorax. Elytra 

 at humeri one-half wider than prothorax at base, 2.5 times as long as 

 prothorax, length to width as 10 : 9; intervals nearly flat, about one- 

 half wider than striae, with a single irregular row of minute punctures 

 bearing minute scales; striae deep, coarse, scales in striae somewhat 

 larger than those on intervals. Scutellum triangular, 0.09 by 0.09 

 mm. Front femora 3.7 times as long as wide. Claws with acute 

 basal tooth.
