Head, prothorax, and legs piceous black, elytra piceous red, 

 propygidium and abdominal segments clothed with yellow scales ; 

 head very rugose, villose, and having in the centre a sharp, conical, 

 not compressed tul)ercle equally developed in both sexes ; clj^eus 

 sharply six-dentate on each side ; prothorax obliquely ampliate 

 laterally from the anterior angle to about one-third of the length 

 whence it is slightly and roundly attenuate up to the base, it is 

 deeply and closely punctured, has a shallow median groove, is 

 briefly pubescent, and fringed with longish black hairs ; the 

 scutellum is somewhat narrow, moderately long, and deeply pitted ; 

 the elytra are gradually ampliated from the shoulder to the median 

 part where they are broadest, and moderately attenuate from there 

 towards the apex ; the diagonal costa on each side is distinct in the 

 male, but less so in the female, in which, moreover, the elytra are also 

 a little less ampliate laterally in the middle, they are somewhat 

 closely and deeply punctured, each puncture bearing a short, black 

 bristle, and in specimens which have not been rubbed, there are also 

 in the median discoidal part, from the base to past the middle, some 

 appressed, slender, fiavescent scales not at all closely set ; pygidium 

 vertical, slightly convex, and without scales ; in the male the hind 

 femora are thickened ; the hind tibiae are as broad but shorter, 

 somewhat deeply excavated inwardly at apex, and they have on the 

 inner side of the excavate part a short, sharp spine set next to the 

 apical spur, and below it a short, blunt process serrate outwardly in 

 the male ; in the female the hind tibiic are thick but simple. 



Length 10-11^ mm. ; width 6^-8 mm.

 This species greatly resembles H. aurivcntris, the facies, size, and 

 sculpture being similar ; some of my examples, however, have
