ill the posterior part there is a well-defined impressed longitudinal 

 line reaching from the median part to the base ; elytra convex, 

 hardly sinuate laterally above the metasternal epimera, geminato- 

 striate and with the intervals plane and having each in the centre a 

 series of elongate, carinate tubercles except on the juxta-sutural one 

 which is very narrow, as well as a supra-marginal carina formed 

 sometimes by two coalescing, very elongate tubercles, and widely 

 disconnected from both base and apex ; pygidium very deeply and 

 rugosely punctured ; metasternum impunctate in the whole of the 

 median part ; apical spur of anterior tibia3 very distinctly bifid at tip, 

 but the inner tooth is a little stronger than the outer. 



Length 6 mm. ; width 3f mm.

Black, opaque ; head rugose laterally, smooth in the centre, 

 impressed on each side of the ocular carina and also in the base, 

 and having in the centre of the frontal part a very small tubercle, 

 genae ampliated laterally as a more or less sharp triangle, sharper 

 in the male ; clypeus produced on each side of the incised apical 

 part into a long, or very long, compressed, recurved horn in the 

 male, and a long triangular, also recurved tooth in the female, and 

 carinate longitudinally in the centre; prothorax simple, slightly 

 emarginate in the centre at apex, and strongly sinuate above the 

 eye, nearly straight laterally if seen from above, but briefly sinuate 

 near the base, covered with very closely set sub-foveolate punctures, 

 and having a very short, basal median impressed line ; elytra less 

 convex than in the other species, very slightly sinuate laterally above 

 the metasternal epimera, geminato-striate, striae not deep and 

 slightly punctate, intervals plane, closely punctulate, and having 

 each one series of elongate, carinate tubercles, except on the juxta- 

 sutural one, where they are absent, between the outer stria and the 

 outer margin there is a very distinct median longitudinal carina 

 extending for about one-third of the length ; pygidium closely and 

 roughly punctured ; edges of abdominal segments very deeply 

 crenulato-punctate, last segment foveolato-punctate ; metasternum 

 quite impunctate between the coxae, and without basal impression 

 or longitudinally impressed line; anterior tibia3 pluri-serrate, the
