Onthophagus flavimargo, d'Orbigny, 

 Ann. Soc. Ent. Fr., p. 59. 



" Moderately shiny, testaceous, head and prothorax green-bronze, 

 sides of the prothorax and base broadly testaceous ; elytra tessellated 

 with black, the minute macules are round and situated between the 

 granules ; glabrous on the upper side ; head briefly but not con- 

 spicuously flavous pubescent in front, also the sides and apex of the 

 elytra, and the pygidium. Head bi-carinate, finely and densely 

 rugose granulate, but with simple punctures on the vertex ; clypeus 

 rounded, anterior carina set a little before the middle, and sub- 

 arcuate, hind carina set between the eyes but slightly past the 

 anterior margin of the eyes and strongly angulate backwards in the 

 centre ; prothorax with simple punctures moderately dense and 

 moderately deep, somewhat unequal and deeper towards the sides, 

 posterior sides sinuate, base marginate ; elytra somewhat finely 

 striate, intervals plane, sparingly and not regularly granulate ; 

 pygidium not densely punctate. 



Length 7-7-J mm. 



Hab. Natal." 



This species, which is not known to me, is compared by 

 d'Orbigny to 0. ambiguus, Pering., but the armature of the head 

 differs. I should not be surprised if it proved to be identical with 

 0. plebejus, Kl. 



Onthophagus limbibasis, d'Orb., 

 Ann. Soc. Ent. Fr., 1905, p. 428. 



*? Female : " Slightly shiny, head and prothorax bronze-green, base of 

 prothorax broadly testaceous ; elytra testaceous, sprinkled with small 

 black rounded patches surrounding a granule ; pygidium testaceous, 

 glabrous on the prothorax but with the sides briefly flavous-pubescent, 

 on the elytra this pubescence is very short, but long towards the 

 apex and also on the pygidium ; head granulate in the anterior part, 

 simply punctate on the posterior, not carinate, having merely a 

 minute tubercle between the eyes, clypeus rounded ; prothorax 

 simply and sparsely punctate, the punctuation being moderately 

 fine and moderately equal in the centre, but intermixed with plainly 

 larger ones towards the sides, sides sinuate behind, base marginate ; 

 elytra finely striate, intervals plane, sparingly and irregularly granu- 

 late ; pygidium sparingly granulate punctate.
