cation. It is not a Heteronychus. The mandibles, instead of being 

 tri-dentate on each side, are a little concave and similar to those of 

 Bhizoplatys, and there is a highly raised frontal carina bearing an 

 emarginate tubercle ; the prothorax has an excavation in the anterior 

 part which is edged in front by a transverse lamellate carina ; the 

 anterior femora are armed with an obtuse tooth ; the anterior tibiae 

 are quadri-dentate, and judging from the example I have seen, the 

 tarsi of the anterior tibiae and also the inner claw are not thickened 

 in the male.

" Oblong, convex, black, shining, under side ferruginous, sternum 

 sparingly villose ; head not rugose ; clypeus triangular, strongly 

 reflexed at tip, mandibles concave, not rounded, and reflexed, and 

 in the frontal part there is a short, bifid, more or less raised tuber- 

 culated carina ; prothorax slightly attenuate laterally in front 

 ampliate and rounded in the middle, very convex and having in 

 the anterior part a triangular impression slightly retuse in front 

 and edged by a vertical, laminate carina, this impression extends 

 a little further than the median part of the disk, and the rest of the 

 surface, with the exception of the posterior part, is unevenly 

 punctured ; scutellum smooth ; elytra parallel, convex, moderately 

 distinctly punctato-striate and with the intervals of the dorsal part 

 very sparingly punctulate, but the punctures on the sides are more 

 numerous and more irregular ; pygidium finely but somewhat 

 densely punctulate except at the base where the punctures are 

 not so numerous ; anterior femora armed not far from the apex 

 with an obtuse tooth, and emarginate at apex, anterior tibiae quadri- 

 dentate. 



Although Boheman gives the whole of Caffraria as the habitat of 

 this insect, which therefore ought not to be scarce, I have seen only 

 one example — one of Boheman's. 



Length 191-21 mm. ; width 10-10^ mm." 



PSEUDOCYPHONISTES, n. gen. 



Mentum not very convex, ovate laterally from the base to past, 

 the median part and a little attenuate obliquely from there, truncate 

 at the tip, and not constricted or grooved laterally for the insertion 

 of the labial palpi which are set in the inner face of the mentum ;, 

 labial palpi moderately short, last joint cylindrical, slightly rounded.
