 Ann. Soc. Ent. Fr., lxxi., 1902, p. 223. 



" Moderately shiny, black, with the shoulders of the elytra, the 

 apex and often the base and side with testaceous macules, briefly 

 flavo-pubescent on the upper side ; head sparingly granulose ; cly- 

 peus completely smooth in the male, but in the female smooth 

 in front only, excised at apex, frontal part arcuately carinate, vertex 

 with a long, nearly straight carina situated between the hind margin 

 of the eyes ; prothorax moderately strongly and sub-densely sub- 

 asperate punctate, more asperous or granulate in front and towards 

 the sides, deeply declivous in front in the male, simple in the female ; 

 sides sinuate behind, base marginate ; elytra tolerably striate, inter- 

 vals plane, not densely granulate, the granules partly bi- seriate ; 

 pygidium strongly punctate, the punctures intermixed with smaller 

 ones. 



Length 4A— 5i mm. 



Hab. Mozambique; Delagoa Bay." 



d'Orbigny compares this species with 0. sugillatus, Klug (Catal. i., 

 p. 214), which differs from it by the moderately projecting and less 

 rounded genas, the sides of the head not sinuate at the junction of 

 the gen® and of the epistoma, the vertex, which in the $ bears 

 usually two horns with their base dentate and a tubercle in the 

 centre in front of the horns, while in the $ the vertex bears a 

 slightly arcuate carina situated well behind the posterior edge of the 

 eyes, and the whole prothorax is entirely granulate. 



Onthophagus rubens, d'Orb., Ann. Soc. Ent. Fr., 1902, p. 238. 

 0. exiguus, Pering., Cat. i., p. 215. 



This name having been used in 1877 by Eaffray for a species from 

 Eastern Africa, d'Orbigny has therefore changed the name of my 

 species.
