on each side. Beak short, smooth and with a median tubercle; an acute 

 ridge each side above the insertion of antennae extending to middle of 

 eyes and continued along their inner margin by a series of stiff yellowish 

 bristles. Thorax convex, slightly wider than long, sides nearly straight 

 rrom base to middle, thence strongly rounded, hind angles rectangular, 

 anterior angles very obtuse; surface strigose-punctate, without smooth 

 median line, flanks densely rugosely punctate. Scutellum feebly de- 

 pressed. Elytra twice longer and at base distinctly wider than thorax, 

 punctate-striate; interstices flat, rather sparsely rugosely punctate, those 

 on disc wider than the strise, narrowing on declivity and each bearing on 

 posterior half of elytra a row of semi-recumbent, short yellowish bristles. 

 Under side with sparse, short pubescence; front coxa? widely separated, 

 antecoxal ridges acute; metasternum rather coarsely punctate; abdominal 

 segments convex, moderately strongly punctate. Anterior legs very little 

 stouter than posterior ones. Length 2.5 mm. (Fig. 139, I.)

Cylindrical. Dark brown, clothed with yellowish hairs, which are 

 more stiff and arranged in rows upon the elytra. Prothorax longer than 

 wide, convex, sides parallel to near tip, where they are rounded, tip two- 

 thirds as wide as base; disc uniformly and densely covered with short, 

 longitudinal aciculate punctures. Elytra with deep punctured striae; in- 

 tervals flat, with very fine rugosities; tip obliquely declivous and broadly 

 sulcate along the suture. (LeConte.) Male, front shining, flattened be- 

 tween the eyes, anteriorly transversely depressed, the depression clothed 

 with short, grayish hair and with a flattened tubercle each side; antennal 

 scape elongate, curved, sutures of club fringed with long and conspicuous 

 hairs. Female, front subopaque, sharply margined between the eyes, an- 

 terior impression deeper, clothed with very dense reddish-brown hair and 

 without tubercles, antennal scape shorter, not curved, hairs of club shorter 

 and very fine. Length nearly 3 mm. (Sctiicarz, Ent. Am., II, 54.)
