the alleged co-type, if not type, of which I have seen, but Fahraeus 

 ascribes to it a thorax with " remote punctures," as well as elytral 

 " intervals sparingly punctate," which is not the case in 0. confertus. 

 This species, however, belongs to a group in which there are no 

 traces of frontal carina in either sex, only a small horn or a 

 tubercle on the vertex. Fahraeus' description of the $ possesses 

 this character, but to the $ he ascribes two frontal transverse 

 arcuate carina?, which could not be applied to 0. confertus. This 

 latter is allied to 0. apiciosus, but differs by the less closely punctate 

 prothorax, which has distinctly a basal fold, and by the more trans- 

 verse carina of the vertex, the said carina being also situated more 

 backwards than in 0. confer his. 



Length 5 mm. ; width 3 J mm. 



Rah. Natal (Maritzburg). 



Onthophagus l^vatus, d'Orbigny, 

 Ann. Soc. Ent. Fr., lxxi., 1902, p. 69. 



" Black, shiny, glabrous ; head minutely and densely punctate, 

 clypeus rugose, truncate at the apex ; frontal part with a long 

 carina produced as far as the outer margin of the head, and having 

 on the vertex a shorter carina situate between the eyes and in the 

 middle ; prothorax minutely and not very densely punctate, the 

 punctures simple, nearly smooth in the posterior half, more deeply 

 and more densely sub-rugosely punctate towards the sides, gibbose 

 in the middle of the anterior part and with a tubercle or a callosity 

 on each side of the apex ; hind part of the sides sinuate, base very 

 finely marginate, the striae briefly sulciform at the base, intervals 

 plane, most minutely and sparingly punctate ; pygidium sub-finely 

 punctate. Club of antennae black or deep fuscous. 



Length 7-9 mm. 



Hah. Mozambique (Delagoa)." 



I have not met with this species, and the description here given 

 is that of d'Orbigny. 



Onthophagus placens, Pering., 

 Ann. S. Afric. Mus., hi., 1904, p. 219. 



Male : Black, very shiny, glabrous on the upper side, but with the 

 epipleural fold punctulate, and with a few fulvous hairs, prosternum 

 hairy, legs sparingly hairy, clypeus semicircular but broadly although 

 not deeply emarginate in front, strongly plicate transversely, sepa- 

 rated from the frontal part by a transverse, not much raised keel 

 extending from one gena to the other, far in front of the eyes, frontal
