of the prothorax is not as highly raised as in the male and is therefore 

 proportionately less declivous, but it is plainly bi-tuberculate ; the 

 intervals of the elytra are plane and very closely punctured ; the 

 closely punctate pygidium is nearly as broad as long in both sexes ; 

 in the male the inner spur of the anterior tibiae is nearly straight, but 

 it is slightly inflexed inwardly at tip in the female. 



Closely allied to 0. pictipodex, d'Orb., but the armature of the 

 head is very different. 0. pictipodex was probably described from 

 female examples. 



Length 8|— 9| mm. ; width 5-5J mm

Onthophagus ubsinus, d'Orbigm, 

 Ann. Soc. Ent. Fr., lxxi., 1902, p. 112. 

 Moderately shiny, black ; elytra brownish red, except for a broad 

 median triangular fuscous patch reaching from the base to about the 

 middle and acuminate there, occasionally there is only a narrow 

 reddish band along the sides and the apex, the upper part is clothed 

 with a somewhat erect and moderately thick flavescent pubescence ; 

 clypeus sub-orbicular, very slightly sinuate in the centre of the 

 anterior part, frontal part with an arcuate ridge between the genaa 

 which are not very greatly projecting, and a transverse, fairly highly 

 raised ridge broadly separated from the eyes, the surface is granulate 

 except at the back of the anterior arcuate ridge ; prothorax not much 

 ampliated laterally, and having thus the appearance of being some- 

 what elongated, the posterior lateral margin is plainly sinuate, but 

 the basal angle is not rounded ; it is covered with closely set, elon- 

 gated granules the intervals of which are setulose, the anterior part 

 is simple and the disk very little convex, on the posterior part is a 

 short supra-basal longitudinal impression, and the base is narrowly 

 marginate ; elytra hardly longer or broader than the prothorax, finely 

 striate, the intervals with two series of granules turning on the sides 

 to asperous punctures ; pygidium covered with round punctures 

 separated by an interval equal to their own diameter, and clothed 

 with the same pubescence as the elytra. 

 Length 3^-3f mm. ; width 2-2£ mm.

Onthophagus graphicus, Wallengr., Catal. i., p. 264. 

 Black, with a very faint metallic tinge on the head and prothorax, 

 but more so on the under side and legs, glabrous ; elytra flavescent
