Hob. Southern Rhodesia (Zambesi River) ; Damaraland (Oma- 

 ruru) ; Ovampoland (Omrramba) ; Transvaal (Pienaar's River) ; 

 Bechuanaland (Kuruman). 



I have found by examination of the sexual characters of the types 

 that S. ncglccta is the female of S. puncticollis. 



SCHIZONYCHA PLAUSIBILIS, 11. Spec. 



This species is so closely allied to S. neglecta that it is at first 

 sight difficult to distinguish the two, but apart from the totally 

 different shape of the genital armature, it is differentiated by the 

 punctures on the prothorax, which are not quite so closely set, 

 especially in the posterior part, the median longitudinal smooth line 

 is also less plainly indicated ; the pygidium is much more broadly 

 punctured, and the epipleural fold of the elytra is distinctly punctate 

 near the basal part ; tarsi long, both teeth of the claws long, upper 

 one longer than the other, and slightly emarginate underneath ; 

 the nearest approach to the shape of the genital armature is that of 

 S. zambesiana, but it is very distinct. 



Length 13-J-- 15 mm. ; width 7-10 mm. 



Hab. Natal (Durban, Umsimkulu, Maritzburg). 



SCHIZONYCHA RUFINA, BoheiTl., 



Plate XLL, fig. 73. 



Insect. Caffr., ii., 97. 



Rusty-red, and with a minute hair in every puncture. In general 

 appearance it very much resembles S. spuria, the shape of the clypeus 

 is the same, but the clypeal carina is more arcuate, and the 

 suture nearly obliterated ; the punctuation of the prothorax is 

 different on account of the punctures being cicatricose and also more 

 asperous in the anterior part of the sides, which are also less am- 

 pliated at about the median part, and less obliquely attenuate 

 towards the basal angle, the median longitudinal smooth space when 

 it occurs is also more conspicuous, and the punctures on the 

 scutellum and elytra are a little broader ; the punctures on the 

 pygidium are also deeper and more cicatricose ; the tarsi are also 

 long, and the upper tooth of the anterior claws which is very curved, 

 is not emarginated underneath. In the female the hind tarsi are 

 slightly shorter than in the male; the penultimate abdominal 

 segment is hardly wider than the preceding one, and the last is 

 swollen ; in the male the penultimate is slightly wider than the 

 antepenultimate, and the last is also very swollen.
