base; margin very narrow; apex broadly, circularly arcuate; collar short and 

 broad ; disk rather convex, densely and strongly granuiato-rugose. Elytra nearly 

 two-thirds longer than wide and about two-thirds wider than the prothorax, 

 the sides parallel and almost straight, slightly arcuate in the female, dehiscent 

 and broadly rounded at apex; humeri well exposed at base; disk even, finely 

 very densely and comiiositely sculptured and opaque. Abdomen shining 

 finely, sparsely punctulate, the legs moderately long and slender. Length 2.9 

 mm.; width 0.75 mm.

The description is drawn from the male, this sex having the 

 fifth ventral rather shorter than the fourth, broadly truncate at 

 apex, with a very feeble sinuation and with a slightl}^ thickened 

 bead-like edge toward the middle ; onl}^ the pygidium is ex- 

 posed at apex. 



Besides the denser, more opaque and differentl}" ornamented 

 elytra, this species diflers from salicola in its relatively smaller 

 head and coarser sculpture of the pronotum.

Narrow, feebly convex, rather shining and scarcely distinctly 

 reticulate, black throughout, the antennaj and legs in part paler ; 

 pubescence fine, very short and not dense. Head fully as long as 

 wide, broadl}' arcuate and not distinctly impressed at base ; the 

 angles very broadly rounded to the small, anterior but somewhat 

 convex ej'es ; punctures large, very shallow and sparse, without 

 trace of a median smooth line ; antennae short, moniliform one- 

 third longer than the head, the subdivided eleventh joint as long 

 as the two preceding. Prothorax trapezoidal, the sides oblique 

 and straight and the apex broadly arcuate, rather small, much 

 narrower than the head and slightly transverse, the punctures 

 large, very shallow and sparse. Elytra one-half longer than wide 

 and thi'ee-fifths wider than the prothorax, with unevenly and 

 sparsely scattered, shallow, craterform areolae, the hairs arising 

 from almost imperceptible punctures of the interspaces. Meta- 

 sternum highly polished. Abdomen shining, not distinctly punc- 

 tured. Legs slender, moderate in length. Length 2.2 mm.; 

 width 0.55 mm.
