Male. — Strongly shining, black, with a vague reddish tinge; body 

 beneath, antennal club, tibiae, and tarsi reddish brown ; palpi, antennae 

 (except clubs), femora, and anterior coxae brownish yellow. 



Head slightly gibbose ; front deflexed along anterior margin, densely, 

 finely punctate, with a longitudinal, median, smooth space, rather 

 densely clothed with moderately long, erect, yellow hairs on each side 

 along anterior margin ; occiput densely, rather coarsely granulose, the 

 granules round at middle and elongate on each side; clypeus flat, 

 coarsely, irregularly punctate, rather densely clothed with moderately 

 long, erect, yellowish hairs, feebly, arcuately emarginate in front; 

 clypeal suture distinct, biarcuate. 



Pronotum distinctly wider than long, widest at basal third; sides 

 broadly rounded posteriorly, strongly converging anteriorly, with a 

 short, unciform tooth at apical angles; posterior angles rectangular; 

 lateral margins arcuate near base ; surface glabrous, smooth and finely, 

 indistinctly punctate on basal half, more distinctly punctate at sides 

 on apical half, densely, irregularly dentate on disk on apical half, the 

 teeth broad, semierect, variable in size, and rasplike, with a few longer 

 teeth on each side toward lateral margin. 



Elytra at base subequal in width to pronotum at basal third ; sides 

 nearly parallel, conjointly broadly rounded at apices, the margins 

 strongly elevated along apical declivity, thickened and more strongly 

 elevated at sutural angles; surface glabrous, rather densely, coarsely 

 punctate, the punctures finer near base and apex ; apical declivity with 

 sutural margins slightly, uniformly elevated, the lateral submargin 

 short, not joined to lateral margin at anterior margin of declivity; 

 each elytron with three more or less distinct costif orm tubercles along 

 anterior margin of apical declivity. 



Abdomen beneath finely, densely punctate, rather densely clothed 

 with short, recumbent, yellowish hairs; last visible sternite feebly 

 emarginate and clothed with long hairs at apex, and with narrow, 

 smooth, lateral pieces. 



Female. — Differs from the male in having the front of the head 

 and clypeus densely clothed with very long, erect, yellowish hairs, 

 forming a transverse, arcuate crown on the front and two tufts on the 

 clypeus, the last visible abdominal sternite more deeply emarginate at 

 the apex, with the lateral pieces smaller and pubescent. 



Length 5-8.5 mm., width 2-3 mm.
