half Avider than the protliorax, gradually wider with the tsides nearly straight 

 to apical third, almost senii-circularly rounded behind; punctures fine hut 

 strong, even and moderately close-set. Abdomen very sparsely and incon- 

 spicuously clothed with plumbeo-cinereous hairs. Length 1.5-1.7 mm. ; width 

 0.6-0.7 mm.

This species is evidently rather closely related to the last, l3ut 

 it differs in vestiture, in its more posteriorly broadened form, in 

 its longer epistoma, and in the less narrowl}' truncate subtrian- 

 gnlar fifth ventral of the female. The description is drawn from 

 that sex for facility of comparison, but the male differs scarcely 

 at all, having the elytra A^ery slightly shorter and the apex of the 

 fifth ventral broadly arcuato-triincate. In both of these species the 

 ungual appendage is full}- developed and as long as the claws. 

 Four specimens.

Narrow, strongly convex, subparallel, strongl}" shining though 

 feebly reticulate throughout, densely so on the head, black, the 

 legs piceous-black ; antenna? black throughout; pubescence mod- 

 erate in length, cinereous, sparse, moderately fine and distinct, 

 decumbent and without trace of erect setoe. Head rather more 

 than three-fourths as wide as the prothorax, much wider than 

 long, very minutel}', sparsel}^ punctate, the epistoma short and 

 with a polished black margin ; labrum dark, transverse, strongly 

 rounded ; eyes small and not very prominent ; antennas short

 toward tip, the penultimate joints transverse. Prothorax two- 

 thirds wider than long, the sides broadly arcuate, more conver- 

 gent and straighter toward apex ; angles all obtuse ; apex and 

 base feebly arcuato-truncate, the former scarcely perceptibly nar- 

 rower; disk finel}" and sparsely punctate, the submarginal im- 

 pressed line distinct particularly toward base, the sculpture 

 slightly' rugose near the sides. Elytra three-fifths longer than 

 wide, scarcely two-fifths wider than the prothorax, the sides 

 parallel and scarcely arcuate, becoming oblique and feeble arcu- 

 ate toward apex, the latter very narrow and obtuse ; disk finely 

 but strongl}^ rather closely punctate. Length 1.75-1.9 mm.j
