Elongate, moderately slender. Black; pubescence conspicuous, 

 fine, long, whitish to j^eUowish white, sparse, uniform. Male beak 

 one-fourth longer than prothorax, nearly straight, cylindrical, sHghtly 

 dilated laterally over antennal insertion; basal two-thirds mod- 

 erately punctured and with sparse pubescence, apex smooth, more 

 shining. Female beak equal to, to much longer than, head and 

 prothorax, one-half to twice as long as prothorax, slightly cm'ved, 

 nearly cylindrical throughout; finely punctured throughout, tip 

 slightly more shining. Antennae of male inserted at distance from 

 eye twice as great as width of frons, at basal two-fifths of beak; of 

 female inserted at distance from eye one-half greater than width of 

 frons, at basal third of beak; first segment about equal to next three; 

 second segment longer than third, shorter than next two; club 0.16 

 by 0.08 to 0.21 by 0.10 mm. Eyes moderately prominent; frons 

 moderately wide, shallowly punctured, alutaceous. Prothorax one- 

 seventh to one-fom-th wider at base than long, middle a little wider 

 than base, apex from three-fourths to four-fifths as wide as base ; sides 

 with very slight lateral expansion at base, diverging slightly to middle, 

 rounding to slightly constricted apex; in profile dorsal surface slightly 

 arcuate, flatter at apex and base; punctation 0.03 mm. in diameter, 

 moderately deep, interspaces variable, less than, to equal to, diameter 

 of punctures; basal fovea shallow, rounded. Elytra one-fourth to 

 one-third wider at humeri than base of prothorax, from 3.2 to 3.5 

 times as long as prothorax, length to width varies from 11:7 to 

 14 : 8.5; intervals nearly twice as wide as striae, variable but convex, 

 with one or two rows of fine punctures bearing fine scales; striae deep, 

 with one row of fine scales. Scutellum triangular, 0.06 by 0.04 mm., 

 with median furrow or not. Front femora of male 3.2, of female 3.8 

 times as long as wide. Claws with acute basal tooth.
