The dark upper surface with pale median line and sides to the pronotum and pale 

 longitudinal stripe at the middle of each elytron make this an easily recognisable 

 species. It is coarsely punctured, shining, and very thinly but evenly clothed above 

 with minute hairs. It closely resembles another East African species (described in 

 the footnote below*), but is smaller and less pubescent, and the elytral stripe only 

 reaches the margin of the elytron at its front edge. 



Family Dynastid^.

 made for it by Fairraaire, but the absence of a horn in the male is us only distinctive 

 feature.

 except in having the pronotum less narrowed at the base.
