quadi'ate vertical lamina strongly bi-dentate and a horizontal, sharp 

 apical mucro almost in a line with the two teeth ; inner claw of hind 

 tarsi not quite half the length of the outer, the latter is cleft. 



Female unknown. 



Length 6-6^ mm. ; width 3^ mm. 



Hab. Natal (Newcastle), Transvaal (Johannesburg). 



Heterochelus persimilis, n. spec. 



Male : Very similar to H. promontorii ; the hind femora and 

 tibiae have the same shape, but the body is a little more elongate, 

 owing to the base of the elytra not being broader than that of 

 the prothorax ; the clypeus is not dentate laterally, the prothorax 

 is distinctly grooved in the posterior part, the punctures are much 

 more scattered, deeper and not scabrose ; the elytra have on each 

 side four narrow bands of white scales and are redder than in 

 H. promontorii but the punctuation is the same ; pygidium black, not 

 scaly ; scutellum densely scaly ; legs black. 



Female : Head and prothorax as in the male, and similarly 

 sculptured ; elytra and pygidium redder than in H. promontorii 2 ■ 



Length 5 mm. ; width 2|- mm. 



Hab. Cape Colony (Willowmore). 



Heterochelus bi-vittatus, Burm., 

 Handb. d. EntomoL, iv., 1, p. 114. 

 Male : Black, with the elytra and the hind legs shining red ; 

 prothorax villose and having a median longitudinal line of white 

 scales ; elytra with a discoidal line of similar scales ; scutellum, 

 abdomen and pygidium clothed with contiguous w^hite scales, but the 

 latter has a median longitudinal denuded line which does not reach to 

 the apex ; clypeus sharply quadri-dentate, the teeth equal ; head and 

 prothorax very closely scabroso-punctate, the pubescence is very long 

 and greyish and along the lateral and basal margins there is a narrow 

 line of white scales ; elytra elongate, attenuate towards the apex, 

 but not deeply sinuate below the shoulder, they are cicatricose and 

 roughly punctate, and have a narrow discoidal impressed interval 

 filled with the white scales, but they are not costulate ; the hind 

 femora are only moderately robust and simple, the hind tibiae are 

 long, strongly swollen inwardly, sharply but briefly mucronate in the 

 inner apical part, and quite similar to those of H. ditiis (pi. xlii., 

 iig. 39) ; apical joint of hind tarsi and claw very long. The shape of 

 the hind tibias is nearly similar to that of H. ditus (pi. xlii., Iig. 39).
