outer tooth of the knee is strongly developed, and the trochanters 

 are not spinose ; the hind tibi8e are curved, dilated towards the apex, 

 concave inwardly with the inner apical part obliquely truncate 

 towards the mucro which is long, curved, and strongly bifid; no 

 apical spur ; hind claws single, simple. 



Female : Elytra darker ; sparsely clothed on the upper side with 

 greyish hairs, which are more squamose on the elytra than on the 

 prothorax ; scales on pygidium and abdomen similar to those of the 

 male. 



Length 4-4^ mm. ; width 2-2^ mm. 



Hab. Cape Colony (Graham's Town, Port Elizabeth). 



Heterochelus bimaculatus, Burm., 

 Handb. b. Entomol, iv., 1, p. 103. 

 Male: Black, with the elytra clothed with yellow scales but 

 having on each side of the posterior part an oblique, elongate, sub- 

 parallel black or dark brown patch; legs reddish brown; clypeus 

 indistinctly bi-dentate in the median part; prothorax covered with 

 lanciform yellow scales moderately dense but looking more like 

 strongly squamiform hairs ; scutellum densely scaly ; the scales on 

 the elytra, which are not costate, are small and very dense, and the 

 postical brown patch reaches from the apical callosity to about one- 

 fifth of the whole length ; the propygidium and sides of the abdomen 

 have yellow scales, but the pygidium is piceous red, and not scaly ; 

 the hind legs are robust, the trochanters are very briefly spinose, 

 and the knees are briefly and equally dentate on each side ; the 

 hind tibiffi are broadly and somewhat deeply excavated underneath 

 for nearly all the length, but the angle of the inner margin is more 

 strongly dentate than the outer, and the mucro is much curved and 

 long ; hind claws simple, single. 



Female : According to Burmeister, the female, which I have not 

 been able to obtain, is sub-squamose, and the pygidium is clothed 

 with squamiform scales. 



Length 5^ mm. ; width 3 mm. 



Hab. Cape Colony (exact locality unknown). 



Hetebochelus oreopygus, Burm., 



Handb. d. Entomol., iv., 1, p. 107. 



Male : This species is closely allied to H. armatus ; but it is a little 



smaller ; the two median teeth of the clypeus are stronger and equal 



in height to the lateral ones ; the vestiture and the disposition of the 



yellow scales are similar, but the pygidium is nude and shining,
