G. viridicollis, Fahr., the former being an Onthophagus, the other a 

 Gaccobius. My description must therefore be amended. 



Type. Bronze, with the head and prothorax bright green, the 

 elytra testaceous red, with the suture green ; the antennal club 

 black, and the legs reddish. Clypeus narrowed in front, deeply 

 scooped there, each angle of the incision triangularly produced, genae 

 projecting ; head simple, sparingly punctate, the punctures bearing a 

 rigid flavescent seta ; prothorax with a fulvescent macule near the 

 anterior angle, simple, moderately ampliate laterally with the basal 

 angles well rounded, base marginate, surface covered with deep, 

 simple, round punctures, each bearing a setulose hair and separated 

 by an interval equal to their own diameter in the dorsal part, and 

 broader on the sides ; elytra ampliate laterally, geminate striate and 

 punctate, with the intervals plane, of equal width in the dorsal part 

 and bearing each a series of briefly setigerous punctures ; pygidium 

 with closely set, deep, setigerous punctures. 



Length 3 mm. ; width 2 mm. 



Hab. Transvaal (Pretoria, Pietersburg) ; Mozambique (Beira).

According to d'Orbigny (Ann. Soc. Ent. Fi\, 1805, p. 386) 

 this species is identical with C. (Onthoph.) convexifrons, Raffr. I 

 doubt whether this synonymy is justified. Raffray, himself an excel- 

 lent and most trustworthy entomologist, gives to the $ a "vertex 

 tuberculatus." None of my examples of C. pudens have a tubercu- 

 late vertex. d'Orbigny considers as a variety examples which are 

 totally dark piceous brown, turning to light brown at the anterior 

 angles of the prothorax, at the apex, and on the sides of the elytra. 



This species occurs also in German East Africa, British East 

 Africa, and the island of Zanzibar. In South Africa it is recorded 

 from Southern Rhodesia (Salisbury and Sebakwe); Transvaal 

 (Lydenburg). 



Caccobius postlutatus, d'Orbign., 



Annal. Soc. Ent. Fr., lxxiv., 1905, p. 388. 



Black, with a metallic sheen, elytra fuscous testaceous on the 



anterior dorsal part and testaceous on the sides and especially 



towards the apex ; shiny, sub-orbicular ; antennae piceous ; clypeus 



triangular from the genae, incised in the centre of the apex with the
