Distinguished from A. procerus, which is also an oblong species, 

 by its very much smaller size and broader and shorter thorax (the 

 thorax in ^. j^rocen^s being for this genus remarkably long), and in 

 the (J also by the shorter and less curved tibia?, and the narrower 

 groove of their uuder-surface.

River Lujenda, East Central Africa (Mr. Last). 



In most of its characters, intermediate between A. cupreus and 

 A. procerus, the latter of which was found in the same neighbourhood 

 by Mr. Last. In A. cupreus, the apex of the pygidium in the ^ 

 is broadly rounded, and the margin equally and only slightly reflexed. 

 This obtains both in East African and West African examples.

E. Lujenda (Mr. Last). A large series of examples offering no 

 Tariation. 



The species is almost exactly intermediate, in structure as well as 

 in locality, between 0. lanista, of the Cape and ISTatal, and O. negus 

 (Eaffray), of Abyssinia. In the latter, the large deep thoracic foveaD 

 are within and behind the horns, in O. lujendcs they lie at the base and 

 in front of each horn, and are smaller, rounder, and better defined.

 triangulariter breviter producto, margine laterali ante angulum basalem
