Colorado. 



The single specimen serving as the type is probably a female. 

 This species is one of the smallest of the genus and is somewhat 

 allied to hystricula, but differs greatly in its coarser, sparser punc- 

 tuation, sparser pubescence and especially in the form of the pro- 

 thorax, which is shorter, more strongly narrowed anteriorly and 

 not at all constricted behind the apical margin.

Oblong, moderately stout, convex, scarcely shining, densely and 

 almost uniformly clothed throughout with short robust recumbent 

 hairs of a dark cinereous tint, and without long erect setae; body 

 black, the legs piceous ; antenna? paler, piceous. Beak very short, 

 stout, densely punctured and setose but not longitudinally grooved, 

 opaque, feebly arcuate and equal in length to the prothorax ; antennae 

 inserted but slightly beyond apical two-fifths, the basal joint of the 

 funicle robust and but little longer than the next two. Prothorax 

 short, fully one-half wider than long, parallel and rounded on the 

 sides, strongly constricted and broadly subtubulate at apex, ex- 

 tremely densely, not very coarsely punctured, without impunctate 

 line. Elytra at base much wider than the prothorax and about 

 three and one-half times as long, the sides parallel and straight, 

 rounded in apical third, with a small sutural notch : striae rather 

 coarsely deeply and closely punctate, not strongly impressed ; inter- 

 vals but slightly wider than the strial punctures, densely punctu- 

 late. Length 2.7 mm.; width 1.25 mm. 



Alaska. Cab. LeConte. Easily distinguishable from the other 

 Alaskan species by its dense and uniform pubescence and shorter, 

 broader, more parallel form. It is doubtful if the name substituted 

 by Gemminger should be retained, as the south African vestitus is 

 possibly a true Erirhinus. The anterior femora in mannerheimi 

 are distinctly toothed; the others are not in a favorable position for 

 observation in the single specimen which I have studied. The pro- 

 notal vittae, mentioned by Mannerheim, are obliterated in this ex- 

 ample, and the small subdenuded spots of the elytra are extremely 

 feebly defined.
