 found in Angola and in the Congo State, and extends 

 north and east to Ruwenzori, Toro, and Entebbe.

Hewitson published the description of acerata in May 

 and that of riDidia, in November 1874. In the descrip- 

 tion accompanying the figures in Exot. Butt, he expresses 

 the opinion that acerata is a form of vinidia, as no doubt 

 it is, but as the name acerata was published first it would 

 appear that it must stand as that of the species. As the 

 mnidia f. is much the commoner I will describe it first, 

 afterwards indicating the differences presented by the 

 other forms.
