punctate ; elytra plane, slightly sinuate laterally, punctate but with 

 the punctures very shallow and minutely setulose, the two dorsal 

 costules are distinct, and the suture raised, the narrow fold of the 

 elytra is black ; under side moderately densely villose, hind legs also 

 villose, the hairs black. 



Female : Black, the elytra light testaceous yellow with the mar- 

 ginal fold only narrowly edged with black ; body shorter, more 

 robust, prothorax and elytra more convex than in the $ ; clypeus 

 nearly parallel, truncate at apex and incised in the anterior margin 

 which is strongly reflexed and make thus the anterior part look 

 concave ; prothorax twice as broad as long, and slightly grooved 

 longitudinally in the centre, moderately sparsely punctured and 

 with the pubescence shorter, and probably obliterated in the only 

 example I have seen ; elytra ampliated in the posterior part ; more 

 distinctly pitted ; pygidium glabrous, plainly convex at apex and 

 having there a marginal fringe of black hairs ; legs and pectus 

 hardly hairy ; hind thighs robust, terminal part of hind tarsi very 

 broadly dilated ; upper hind spur expanded at apex like a tennis 

 racket ; anterior tibiae with two long, strong outer teeth and a 

 smaller but distinct one above the two ; antennae piceous red. 



Length 13^-18 mm. ; width 7j— 8J mm. 



Hab. British Bechuanaland (Eamoutsa).

Male : " Clypeus not much longer than the head, anterior margin 

 angularly pointed, no lateral incision before the insertion of antennae,

 hollow, sharply raised and rounded, sharp laterally at end, and 

 having a blunt angular rise in the centre of the anterior margin ; 

 prothorax shorter than in the preceding species (I. cuspidata), more 

 convex, strongly punctate, slightly grooved longitudinally in the 

 centre, opaque black, like the punctured scutellum ; elytra dirty dull 

 yellow, moderately raised, somewhat longer than the preceding 

 species, and having on each side two weak costae and shallow 

 scattered punctures ; pygidium opaque ; under side strongly shiny 

 black, punctate and hairy as in the other species ; legs also just the
