the sides minutely serrulate, feebly convergent and very slightly arcuate from 

 the broadly rounded and apparently obliterated basal angles to the apex, the 

 apical angles but slightly obtuse; apex quite distinctly narrower than the 

 base, both feebly arcuate; disk smooth, minutely and remotely punctate, ab- 

 ruptly rugose near the sides. Elytra parallel, three-fifths longer than wide, 

 not quite one-third wider than the prothorax, the sides nearly straight; apex 

 evenly but obtusely rounded; disk finely but strongly and closely punctate, 

 the interspaces shining. Under surface finely and sparsely pubescent. Length

Oblong, parallel, feebly convex, polished, black ; legs red with 

 the femora black ; antenna? black throughout ; pubescence short, 

 rather dense, cinereous, intermixed anteriorl}^ with sparse erect 

 blackish hairs, and, on the elytra, with extremely short erect cine- 

 reous setae. Head four-fifths as wide as the prothorax, flat, 

 smooth, strongly and closely punctate, the impressions subob- 

 solete ; frontal margin broadly tumid and impunctate; epistoma 

 ver}' short and broad, the labrum moderate, broadly rounded at 

 apex ; ej'es small and prominent ; antennte long, filiform, as long 

 as the head and prothorax, the joints rounded, the tenth slightly 

 wider than long, the eleventh longer than the two preceding and 

 a little wider, gradually' pointed in apical two-thirds. Prothorax 

 three-fifths wider than long, the sides subparallel and rather 

 strongh^, evenly rounded throughout, the edges minuteh' ser- 

 rulate ; basal angles broadly- rounded and obsolete; apex just 

 visibly narrower than the base, both ver}- feebly arcuate ; disk 

 finely but strongly, rather closel3'^ punctate, abruptly and coai'selj^ 

 reto-rugose at the sides, the line of demarcation not impressed. 

 Elytra one-half longer than wide, less than one-third wider than 

 the prothorax, parallel and nearly straight at the sides, evenly 

 rounded in apical third, the punctures fine but somewhat strong 

 and close-set. Length 2.2-2.4 mm.; width 0.85-1.05 mm.
