inner apical part developed into a long spine curving inwards, outer 

 part simple ; tibiae comparatively short, strongly curved, grooved 

 underneath in the anterior part only, dilated in the apical into a 

 conspicuous sub-quadrate lamina continued as a long, curved mucro 

 at the lower apical part, the upper being only angular, the inner 

 edge of the groove is moderately dented near the knee ; inner claw 

 cleft and only slightly shorter than the outer. 



Female : Colour and vestiture of the male, but the scales on the 

 elytra are more hair-like. 



In general build this species is not unlike H. natalensis, but the 

 shape of both the hind femora and tibiae is different, and the pygidium 

 is completely covered with yellow scales instead of being velvety 

 black as in H. natalensis. 



Length 5-6^ mm. ; width 2f-3 mm. 



Hab. Transvaal (Pietersburg). 



Heterochelus shilouvanus, n. spec. 



Male : Black with a greenish metallic sheen which is very distinct 

 on the sides of the prothorax, and still more so on the two discoidal 

 costae of the elytra and the suture ; hind legs red ; head with the 

 anterior corners sub-dentate ; prothorax not scaly, but clothed with 

 long, greyish, partly appressed hairs ; scutellum scaly, the scales 

 long ; elytra of the usual shape, sharply costate and with the suture 

 conspicuously raised and denuded, the intervals filled with short, 

 lanceolate greyish flavescent scales forming three distinct bands ; 

 propygidium and pygidium covered with contiguous yellow scales ; 

 pectus and legs densely hairy ; hind femora greatly developed, armed 

 underneath with a long, horizontal, nearly cylindrical trochanterine 

 spine projecting at one-third of the length and with an hamate, robust 

 tooth in the inner part of the apex; tibiae not deeply grooved under- 

 neath near the base, provided inwardly with a sub-basal quadrate 

 tooth, and three sub-serrate ones at a short distance from it, the 

 apical inner angle is produced into a long, falcate mucro ; the inner 

 tooth is about one-half of the length of the other, broad and cleft 

 at the tip. 



In shape the hind legs are similar to those of H. armipes, from 

 which it is easily distinguished by the strongly costate elytra and 

 the concolorous pygidium ; H. natalensis is its nearest ally in the 

 form of the body and the colour of the hairs and scales, but not so in 

 the shape of the legs nor of the vestiture of the pygidium, which 

 is wholly velvety black. 



Female unknown.
