as long as the four preceding, inner claw broad, compressed, very 

 long, flexed inwardly underneath and moderately sharp at tip ; the 

 intermediate and posterior tibiae end in two and three long spines 

 respectively, and the two median transverse carinse are strongly 

 dentate on the inner side. 



This genus includes only one species the habits of which are not 

 known, but I suppose that they are similar to those of Pseudo- 

 cyphonistes ; it has very wide range in South Africa, and is also 

 recorded from Zanzibar. 



Cyphonistes vallatus, Wiedem., 

 Zool. Magaz., ii., 1, p. 4. 



Piceous black, shining, under side and legs piceous or piceous red, 

 pectus densely villose ; head smooth in the male, very rugose in the 

 female, armed in the centre in the male with a flattened horn, slightly 

 curved backwards and strongly furcate at tip in the large develop- 

 ment, varying in size in the smaller, being less distinctly furcate at 

 tip as the size decreases, and with only a small, yet distinct bifid 

 tubercle in the female ; prothorax abruptly retuse in front, and with 

 the anterior part produced into a compressed, sub-horizontal horn 

 strongly bifid at tip, and about 4 mm. long and broad in the 

 large development ; in the female the prothorax is simple, but very 

 deeply and somewhat closely punctured on the sides and in the 

 anterior part, and with the punctures more remote in the centre and 

 the posterior part of the disk, while in the male they are only punctu- 

 late on the sides of the posterior part ; elytra covered all over with very 

 conspicuous, cicatricose punctures, crowded together, especially along 

 the sides, and with the four duplicate striae fairly distinct from the 

 base to three-fourths of the length in both sexes ; propygidium very 

 finely pubescent, pygidium smooth and shining in the whole of the 

 median part in the male, and with the upper ledge very rugose, and 

 the lower less so in the female ; in the male the last abdominal 

 segment has a broad, transverse, reddish brown, moderately arcuate, 

 membranaceous margin which is quadrate in the female, and the 

 abdominal segment proper is produced in the middle into a sharp 

 spine reaching to three-fourths of the length of the membranaceous 

 part, and overlapping it. 



Length 26-31 mm. ; width 13-17 mm. 



Hab. Cape Colony (Mossel Bay, Knysna, Kowie), Natal (Durban), 

 Transvaal (Potchefstroom, Eustenburg, Johannesburg), Southern
