Male. — Strongly shining, brownish black to reddish brown, the 

 reddish-brown specimens usually with apical declivity of elytra brown- 

 ish black ; antennae, palpi, and usually legs brownish yellow. 



Head moderately convex, vaguely, transversely depressed near occi- 

 put, sometimes with two vague tubercles on front, densety, finely gran- 

 ulose or punctate, sparsely clothed with short, recumbent, yellowish 

 hairs; clypeus flat, sparsely, finely punctate, sometimes vaguely de- 

 pressed at middle ; clypeal suture vaguely indicated ; mandibles without 

 a distinct tooth near base on dorsal surface. 



Pronotum slightly wider than long, widest near middle, arcuately 

 declivous along anterior margin ; sides broadly rounded, more strongly 

 converging anteriorly, with a broad, erect tooth at apical angles; 

 posterior angles broadly rounded ; surface sparsely clothed with long, 

 fine, erect hairs along sides on anterior half, and with short, recum- 

 bent hairs on basal half, very finely, sparsely, irregularly punctate 

 at sides on basal half, rather densely covered with small, cuneiform 

 reliefs at middle on basal half, densely, irregularly dentate on apical 

 half, the teeth broad, semierect, variable in size, and rasplike, with a 

 few larger teeth on each side toward apical angles, densely, finely 

 granulose along anterior margin. 



Elytra at base subequal in width to pronotum at middle; sides 

 slightly expanded posteriorly, conjointly broadly rounded at apices, 

 not tuberculate on underside of lateral margins; surface densely, 

 coarsely, deeply punctate, the punctures coarser on apical declivity, 

 and usually arranged in rows between tubercles, densely clothed with 

 short, recumbent, yellowish hairs on apical declivity ; apical declivity 

 with lateral submargins moderately elevated and united with lateral 

 margins along declivity, then curving inward to near outer tubercles, 

 the sutural margins slightly elevated; each elytron with three long, 

 strongly elevated, costiform tubercles along anterior margin of apical 

 declivity, the tubercles obtusely rounded at apices. 



Body beneath finely, densely punctate, rather densely clothed with 

 moderately long, recumbent, yellowish hairs; last visible abdominal 

 sternite broadly rounded at apex. 



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

 flattened or concave, limited posteriorly by a transverse, arcuate eleva- 

 tion and with surface finely, sparsely punctate, the mandibles with 

 a distinct tooth near the base on the dorsal surface, the first segment 

 of the antenna with long, dense pubescence, the pronotum broadly 

 concave behind the anterior margin, densely granulose and densely 

 clothed with long, erect, yellowish hairs, the last visible abdominal
