patches separated by a narrow testaceous band, the suture is 

 faintly fuscous, the whole surface of the body is covered with fine 

 appressed not squamose hairs ; the head is granulose, the clypeus is 

 slightly oblique laterally at base and rounded in front in the male, 

 quite semicircular with the margin plainly reflexed in the female, 

 the punctures on the prothorax are deep, broad, somewhat closely 

 set, the elytra are faintly costulate, and the intervals deeply and very 

 closely punctured ; the sheath of the genital armature of the male is 

 open on the upper side, elongate, moderately declivous, bi- sinuate 

 laterally, narrowing towards the apex where it is incised in the centre 

 with the sides very obliquely narrowed. 



Length 10-11^ mm. ; 5-6 mm. 



Hah. Transvaal (Johannesburg). 



Adoketus exasperans, n. spec. 

 Plate XLI., fig. 16. 



In colour, shape, size, and sculpture this species is so very much 

 like ^4. impurus that it is most likely to be confused with it 

 unless the difference in shape of the genital armature of the 

 male is noticed. The sheath is equally long, and also bi-sinuate 

 laterally, but it is a little more deeply incised in the middle at the 

 apex and sharply dentate laterally. 



Length 11 mm. ; width 5f mm. 



Hah. Cape Colony (Fort Beaufort). 



Adoretus fraudator, n. spec. 

 Plate XLI., fig. 17. 



Colour, shape, and size of the two preceding species, but the 

 prothorax has no discoidal infuscate patch, the clypeus is more 

 rounded at the apex, the punctures on the elytra are a little broader, 

 and the suture is hardly infuscate ; the club of the antennae is much 

 more elongate, being nearly as long as all the joints taken together, 

 and the shape of the genital ai'mature differs considerably ; it is open 

 on the upper side and suddenly very sharply acuminate from about 

 the median part to the apex where it is narrowly incised, somewhat 

 in the manner of A. mashunus, but it is less declivous. 



Length lOJ mm. ; width 5 mm. 



Hah. Natal (Eshowe). 



Adoretus latiusculus, n. spec. 

 Female: Testaceous without any metallic sheen, head, median part 

 of the prothorax and shoulders somewhat infuscate ; clypeus half as
