incised laterally, and has the anterior keel and the frontal suture of 

 Gamenta, but the gense are considerably developed and project 

 beyond the eyes, the head is somewhat declivous, and the broadly 

 ampliated, convex elytra give to the species included in this genus the 

 appearance of a Trochalus ; the anterior tibiae are strongly bi-dentate 

 outwardly, the claws are those of C 'amenta, the abdominal segments 

 are not free although the sutural line is deep, but the hind femora 

 are nearly as laminate as in Trochalus, and the short hind tibiae are 

 also short, broad, and although bi-dentate on the upper edge, have 

 no oblique ridge on the outer side.

Head, prothorax, and scutellum black, very shining ; elytra as 

 black as the prothorax, or having on each side a large basal reddish 

 patch which often invades the whole surface, abdomen reddish, 

 pectus piceous-red ; antennae occasionally brownish in the male, but 

 almost always navescent in the female, the 10-jointed antennae 

 of the male have a 6-jointed club longer than the pedicel the fifth 

 joint of which is plainly angular at the base, the antennae are 

 9-jointed in the female, and the 4-jointed club is as long as the 

 pedicel the fourth joint of which is aculeate, and the fourth and 

 third are almost fused ; the clypeal keel and suture are very plain, 

 and the punctures of the whole head are moderately closely set ; the 

 short, convex prothorax is very faintly aciculate in the male, but 

 finely punctate in the female, except in the median posterior part ; 

 elytra short, ampliato-ovate, convex and having somewhat seriate 

 rows of shallow punctures without any traces of costules ; pygidial 

 part deeply and closely punctate ; abdominal segments weakly punc- 

 tulate, pectus sparsely hairy. 



Length 5J-7J mm. ; width 4-5 mm.
