Adoretus flaveolus, Fahr., 



Plate XLI., fig. 24. 



Insect. Caffr., ii., p. 75. 



Very closely allied to A. exasperans and A. fraudator, especially 

 to the latter, the colour is the same, but the clypeus is nearly straight 

 at the apex in the <? with the angles rounded, the punctures on the 

 prothorax are more shallow, the costules on the elytra are a little less 

 noticeable ; the colour of the body is pale testaceous, with the head 

 somewhat infuscate in the posterior part, the suture is hardly darker 

 than the background of the elytra, and the tarsi are brownish ; in shape 

 the clypeus resembles that of A. exasperans and A. impurus, but it 

 is transversely straighter at the apex, and the shape of the genital 

 armature of the male differs from both, being broader, shorter, more 

 ovately open on the upper side, abruptly acuminate near the apex, 

 and narrowly cleft there. 



Length 9-9|- mm. ; width 4|-5^ mm. 



Hab. Southern Rhodesia (Salisbury, Sebakwe). 



Adoretus cribrosus, Har., 



Plate XLI., fig. 19. 



Coleopt., Heft, v., 1869, p. 124. 



A. cribratus, Blanch., Cat. Coll. Entom., 1850, p. 234. 



Testaceous brown, very faintly metallic, head fuscous, median 

 part of prothorax sometimes slightly infuscate in the discoidal 

 part ; clypeus semicircular, scabroso-punctate, separated from the 

 head by a very distinct carina, head moderately closely punctate, 

 and with a somewhat more distinct metallic sheen, each puncture 

 bears a small whitish appressed hair; prothorax covered with closely 

 set but not contiguous, and somewhat irregular, small, deep punctures 

 emitting each a very fine whitish appressed hair ; scutellum closely 

 punctured ; elytra very plainly costate, the costae smooth and im- 

 punctate and having each a series of very distant, short white 

 bristles, the intervals are filled with irregular, deep, nearly con- 

 tiguous punctures separated by raised, sinuose walls, the suture 

 is raised, they are not strongly callose at the apex, and each 

 puncture bears a very minute greyish-white hair ; the pygidium, 

 under side, and legs are somewhat thinly clothed with greyish 

 appressed hairs ; all the tarsi are reddish brown ; the sheath of the 

 genital armature is entirely open on the upper side, not very 

 declivous, sinuate, deeply emarginate laterally, at a short distance 

 from the apex, very slightly incised at the middle, the inner angle 



genital armature is dilTerent from that of both A. capicola and A. punctipennis. 

 Length 13 mm. ; width 6^ mm. 



Hah. Southern Ehodesia (Sebakwe). 



Adoretus simplex, n. spec, pi. xliii., fig. 30. 



Shape, size, and sculpture of A. imjmriis, but the colour is a little darker, and 

 the coating of squamulose hairs is a little denser, the clypeus of the male is 

 plainly truncate instead of being arcuate, as in A. impurus, and is therefore more 

 like that of A. exaspercnis, but it is even straighter than in this last-named species, 

 and the genital armature is very different in shape from that of any of the other 

 South African species. Length lOi mm. ; width 5 mm. 



Hab. Southern Bhodesia (Sebakwe).
