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, gene strongly developed, slanting; antenne 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 ; cox less broad than in most Sericine ; 
covering only the basal abdominal segment; anterior tibiz tri- 
dentate, tarsi long, claws normally cleft in both sexes, but with 
the teeth more developed in the male than in the female; upper

Testaceous, or testaceous-red, glabrous, club of antenne flavescent ; 
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 gene, 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
