Male. — Brownish black to dark reddish brown, with base of .elytra 

 reddish or brownish yellow ; antennae, palpi, anterior coxae, last visi- 

 ble abdominal sternite in part, and legs (except anterior tibiae) 

 brownish yellow. 



Head slightly convex, with two small, median tubercles on front, 

 sometimes with a longitudinal groove between tubercles, densely, finely 

 granulose on front, with fine, longitudinal, parallel costae on occiput, 

 sparsely clothed with short, recumbent, inconspicuous hairs ; clypeus 

 vaguely convex, sparsely, shallowly punctate or finely granulose, 

 sparsely clothed with short, recumbent, inconspicuous hairs; clypeal 

 suture deeply depressed at middle, obsolete at sides. 



Pronotum quadrate or slightly wider than long, widest along mid- 

 dle; sides vaguely rounded or parallel along middle, more strongly 

 converging anteriorly; apical and posterior angles broadly rounded, 

 the former usually with a small tooth near margin ; surface sparsely 

 clothed with short, recumbent, inconspicuous hairs, with a few rather 

 long, semierect, arcuate hairs on apical half toward lateral margins, 

 smooth and indistinctly punctate at sides, finely, densely scabrous at 

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

 half, the teeth broad, semierect, variable in size, and rasplike. 



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

 nearly parallel, conjointly broadly rounded at apices ; surface glabrous 

 on disk, rather densely clothed with short, recumbent, yellowish hairs 

 on apical declivity, coarsely, densely, irregularly punctate on basal 

 two-thirds, the punctures finer toward sides and base ; apical declivity

 tubercles, the sutural margins slightly, broadly elevated, and lateral 

 margins strongly elevated; each elytron with three costiform tuber- 

 cles along anterior margin of apical declivity, the two inner tubercles 

 short and obtuse at apices, the outer one long, and usually spinose at 

 apex, and without distinct costae at base.
