Dark brown, antenna? and feet ferruginous-yellow; front scarcely hairy. 

 Head of male strongly punctured, rather flat, broad but slightly concave in 

 front; of female, strongly punctured, uniformly convex, with a slight callus 

 in the front. Thorax roughly tuberculate in front, punctured behind, with 

 a faint, smooth dorsal carina. Elytra glabrous, distinctly punctured, but 

 not in rows, since the intervals between the rows are punctured as strongly 

 as the rows themselves; a faint longitudinal groove along the suture, tip 

 rounded; declivity almost without cusps, slightly more retuse in female 

 than in male, but the suture is strongly elevated in both and armed with 

 two or three slight spines. Length 2 mm.

Slender, cylindrical. Piceous, shining, thinly clothed with long, erect 

 yellow hair. Antennal club thicker, obliquely truncate at tip, proximal 

 half smooth and shining, limited by a curved line. Thorax longer than 

 wide, granulato-asperate for more than half the length, sides and behind 

 densely and coarsely punctured, smooth median line rather wide, more or 

 less distinct. Elytra coarsely punctured, though not in altogether regular 

 rows, suture elevated and sutural stria deep for the whole length, declivity 

 of female oblique, retuse, the concave part coarsely punctured; there are 

 two acute discoidal cusps and several small indistinct marginal ones, the 

 most anterior of which is near the suture and more prominent: (Fig. 149, 

 D.) Front tibia? moderately dilated, two to four dentate. Punctures of 

 prothorax and elytra coarser and more numerous than in liopldnsi. Male, 

 head flat, shining, hairy with very long yellow hair; the four larger teeth 

 of apical declivity less prominent. Female, head finely punctured, carinate 

 with an acute elevated line; four larger teeth of apical declivity very prom- 

 inent. Length 2.3 2 : 5 mm. 



Female described from Marquette, Mich. Male described as
