ricus, but in the latter there is only one broader dorsal band and an 

 outer marginal one, the hind femora have a very strong mucronate 

 tooth underneath at some distance from the knee, which is com- 

 pletely absent in H. karrooanus, the inner part of the tibiaB of which 

 is almost parallel and denticulate, and the mucronate inner apical 

 part less developed and bearing no spur underneath. 



Length 6^-7 mm. ; width 4-4f mm. 



Hab. Cape Colony (Willowmore). 



This species is to follow H. chiragricus, Catal., Scarab., i., p. 736. 



Heterochelus cristaticeps, n. spec. 



Male : Black with the elytra triangularly flavescent from the base 

 to past the median part ; clypeus very little narrowed in the anterior 

 part, straight and simple in front with the angles plain, but not 

 denticulate ; from the apex of the head to the median part of the 

 clypeus are three transverse, parallel rows of upright, closely set and 

 long, spine-like black bristles ; prothorax shagreened, clothed with 

 a brief, black pubescence, moderately deeply grooved in the centre, 

 and having no vestiges of scales ; scutellum of the normal shape ; 

 elytra strongly attenuate behind, non-costulate, very briefly pubes- 

 cent ; propygidium and upper sides of abdomen clothed with long 

 light fulvescent hairs ; pygidium deeply punctate, glabrous in the 

 male ; hind thighs short, moderately robust, hind tibiae also short, 

 gradually dilated towards the apex, nearly as broad there as the 

 thighs, slightly concave inwardly, simple, and with an apical spur ; 

 the upper margin bears a bristle-like spine above the supra-apical 

 sinuation ; anterior tibiae strongly tri-dentate, hind tarsi with a 

 single simple claw. 



Female : Like the male, but the transverse row of bristles on 

 the clypeus is very minute and the elytra are completely flavescent 

 the pubescence on the sides of the abdomen and the pygidium, which 

 is also red instead of black, is greyish and only moderately dense. 



Length 4^—6 mm. ; width 2^-3 mm. 



This species might at first sight be mistaken for an Omocrates on 

 account of the strong attenuation of the posterior part of the elytra ; 

 transverse rows of the singular spines on the head are also met witli 

 in some species of Omocrates (0. mendax). 



Hab. Cape Colony (Uitenhage). 



This species is to follow H. minutus, Cat. i., p. 753. 



Heterochelus griseus, n. spec. 

 Black with legs red, and clothed on the prothorax and elytra with 

 nearly contiguous, narrowly lanceolate, somewhat greyish scales, the
