half Avider than tlie prothorax, gradually wider with the sides nearly straight 

 to apical third, almost semi-circularly rounded behind; punctures fine but 

 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, but 

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

 its longer epistoma, and in the less narrowly truncate subtrian- 

 gular 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 elj'tra xery slightly shorter and the apex of the 

 fifth ventral broadly arcuato-truncate. 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 setse. Head rather more 

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

 long, A^ery minutely, sparsely punctate, the epistoma short and 

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

 rounded ; eyes small and not very prominent ; antennte short 

 though one-third longer than the prothorax, strongly incrassate 

 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 scarcel}' perceptibly nar- 

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

 pressed line distinct particularly toward base, the sculpture 

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

 wide, scarcel}^ two-fifths wider than the prothorax, the sides 

 parallel and scarcely arcuate, becoming oblique and feeble arcu- 

 ate toward apex, the latter ver}' narrow and ol)tuse ; disk finely 

 but strongl}', rather closely punctate. Length 1.75-1.9 mm.; 

 width 0.8-0.85 mm.
