suture, and having in the middle a triangular ridge, anterior edge 

 very strongly reflexed, tri-dentate, the anterior margin is so much 

 reflexed that there is a deep depression on each side of the anterior 

 part, genae strongly developed, slanting ; antennae 10-jointed, joints 

 3-5 short, of nearly equal length, 6-7 compressed, the latter some- 

 what aculeate, club tri-jointed, as long as the pedicel in the male ; 

 prothorax nearly twice as broad as long, slightly narrowed laterally 

 in anterior part, slightly bi-sinuate in front and behind, moderately 

 sloping forwards ; scutellum acuminate at tip ; elytra elongated, sub- 

 cylindrical ; pygidium convex ; coxae less broad than in most Sericince ; 

 covering only the basal abdominal segment ; anterior tibiae tri- 

 dentate, tarsi long, claws normally cleft in both sexes, but with 

 the teeth more developed in the male than in the female ; upper 

 hind spur longer than the basal joint which is only half the length 

 of the second in both sexes.

Testaceous, or testaceous-red, glabrous, club of antennae navescent ; 

 clypeus tri-dentate in front owing to the median part of the 

 anterior, strongly reflexed margin being sharply aculeate, plainly 

 concave on each side of the anterior part, straight laterally in the 

 basal, slightly rounded in the anterior, median keel widely triangular 

 and almost connected with the genae, deeply punctate in the interval 

 between the keel and the frontal suture, frontal part less deeply 

 punctate ; prothorax a little attenuate laterally in front, slightly 

 rounded in the posterior, a little more so in the female than in 

 the male, moderately sloping, deeply punctate, the punctures being 

 separated by a smooth interval about equal to their diameter ; 

 scutellum closely punctate ; elytra elongated, slightly ampliated 

 behind in the female, not plainly striate except along the suture, 

 but with three or four faintly raised costules on each side, intervals 

 irregularly and somewhat coarsely punctate ; pygidium deeply 

 punctate.
