not sulcate longitudinally, produced in the ^ in a large tooth 

 on each side behind the anterior angles, minutely bi-tuberculate 

 on the disk before the median part, and depressed on each side 

 between the tooth and the tubercle, sometimes quadri-tuberculate in 

 front with the median tubercle separated from the external ones by a 

 depression ; in the 2 it is tuberculate on each side in front but more 

 towards the sides, the median part being broadly angularly arcuate ; 

 in both sexes the sides are strongly sinuate behind, and the base, 

 which is finely marginate on each side, is expanding in the centre 

 and angularly produced there ; elytra minutely striate with the 

 intervals plane, simply and moderately densely punctate, the third 

 and the fifth are narrower than the others, sub-convex and sparsely 

 punctate : pygidium strongly punctate. 



Length 11^—13 mm. 



Hab. Natal. 



This species is allied to 0. stib-extenstis, Kolb. ; 0. higendce, Bat. , 

 0. insignis, Per. ; and 0. lanista, Cast. 



Onthophagus (Pboag.) tubeeculicollis, Casteln. 

 Hist. Nat. Coleopt., ii., 1840, p. 84. 



It is very doubtful if the habitat " Cape of Good Hope " given 

 by Castelnau is a true one. d'Orbigny records the species from 

 Abyssinia.

" Shiny, metallic green, head golden, median posterior part of the 

 prothorax dark blue with a violaceous tinge, suture of elytra and 

 apex of the same greenish ; upper side briefly flavous pubescent, 

 disk of prothorax glabrous, elytra very briefly nigro-setose. Head 

 granulate, rounded in front, with a nearly straight transverse ridge, 

 and having a moderately raised longitudinal smooth line extending 

 from the ridge to the posterior margin; between the eyes there is, on 

 each side, a minute but sharp tubercle which is, however, sometimes 

 indistinct : prothorax granulate towards the sides, smooth in the 

 centre from the base to the anterior margin, this smooth part is 

 broad on the disk, much narrower and sub-depressed longitudinally 

 in front, the depression being punctate; sides sinuate behind, margin 

 not distinctly marginate, flattened and angularly produced; elytra 

 not broadly striate, intervals plane, strongly and moderately densely 

 asperate punctate, but sparsely so in the anterior part towards the 

 suture ; pygidium strongly and nearly simply and sparsely punctate.
