 anteriorly from basal angles, without isolated grooves or ridges; 

 supraantennal prominences very large; with rather indefinite ground 

 sculpture between the strigae; clypeus rounded in front; labrum 

 transverse, concealed; antennae rather slender, segments transverse 

 from eighth to tenth only ; mandibles not elongate ; third segment of 

 maxillary palpus very large, cup-shaped, fourth as long but nar-

 absent in male. Pronotum over one-third wider than long, as wide as 

 head (in male) ; widest near apex and moderately narrowed to base; 

 sides biarcuate, margin double because of complete ridge forming 

 secondary margin and setting off a deep lateral groove scarcely visible

 along midline, deeper in front where it divides a transverse mar- 

 ginal prominence; rest of surface densely longitudinally strigose as 

 head, but with ground sculpture a little more distinct. Elytra one-

 with strigae as on pronotum but stronger, less dense, and occasionally
