Also at Kimberley, and Ababis, S.W. African Protectorate (R. W. 

 Tucker). These agree with Forel's description in every way except 

 the colour, which is darker, almost pitch-black, the tarsi and the apex 

 of the flagellum dark reddish-brown. From an examination of these 

 specimens and of a co-type ( $ media) in my possession, it appears to 

 me that the emphasis laid on the presence of a tooth on the scape is 

 somewhat misleading. Unless seen at a certain angle from above, 

 this dentiform projection at the base of the scape is by no means 

 conspicuous, and moreover, a similar though smaller tooth occurs in 

 capensis and its var. pseudoaegyptiaca. Denticornis differs from the 

 latter species chiefly in its much more shining integument, in its 

 feebler and more superficial sculpture of the head, and by its 

 narrower form.

" $ . Differs from the type by the much smaller tooth on the 

 scape. Some specimens have also more obliquely exsertecl hairs on 

 the tibiae.

" $ . 6-8'5 mm. Allied to var. parvidens but smaller, of a light 

 brownish-red, with the tarsi, antennae and mandibles yellowish-red or 

 reddish-yellow. The sculpture of the head is finer and closer, and the 

 occiput is transversely striate (longitudinally so and more rugose in 

 the type of the species and var. parvidens).
