Fuscous brown on the upper side, with the clypeus, the sides of 

 the prothorax and the elytra lighter brown, under side and legs 

 testaceous red, hind legs somewhat infuscate ; clypeus straight 

 laterally at the base, rounded thence but distinctly emarginate 

 in the centre in the male, but not in the female, the suture with 

 the head is slender but distinct, and both the head and clypeus 

 are scabrose and covered with dense greyish hairs ; prothorax also 

 clothed with dense appressed hairs, it is very closely punctured, and 

 has a metallic sheen; elytra plainly tri-costulate on each side, deeply 

 punctured and clothed with fine, short, very closely set appressed 

 hairs, the three costae of the elytra are regularly hairy but have 

 a tesselate appearance owing to the hairs being interrupted at 

 regular intervals by denuded, transverse patches ; the sheath of 

 the genital armature of the male is entirely open on the upper 

 side, slightly sinuate laterally but sub-parallel for the greater part 

 of the length and obliquely truncate on each side towards the apex 

 which is not deeply emarginate and is not cleft. 



This species is very closely allied to A. obsciirus from Senegambia. 

 The shape of the head and vestiture are identical, but the sheath of 

 the genital armature is not so obliquely truncate laterally and is 

 broader at the apex. 



Length 9-11 mm. ; width 5-6 mm.

Plate XLI., fig. 21. 



Pale testaceous, with the head and the hind tibiye fuscous black,^ 



clotlied with greyish moderately dense greyish hairs ; closely allied 



to A. fraud 11 lent us and to A. Jiavcolus, but differs from the former in 



having the clypeus more truncate in front, and from the second in it 



Adoretus disparilis, n. spec, pi. xliii., fig. 31. 



Pale testaceous, slightly metallic, and covered on the upper and under sides and 

 also on the lej^s with somewhat long and very dense squamulose, appressed, 

 flavescent hairs, so closely set on the scutellum as to hide the whole surface ; the 

 clypeus is rounded laterally and truncate in the anterior part in the male, sub- 

 acuminate tliere in the female, in which the median lateral part of the prothorax is 

 also slightly more ampliate than in the male ; the elytra are plainly costate ; the 

 joints of the tarsi are very short, but the apical one is long and very robust in the 

 male, and in both sexes the apical outer tooth of the anterior tibia; is a little 

 shorter than in the intermediate. The genital armature differs much from that, 

 of the other South African species. Length il-'.H mm. ; width 4:^-45 mm. 



Hah. Southern Rhodesia (Sebakwe).
