I took this species only in the Luangwa valley, ii., iii., where 

 it was scarce. 



Caprona pillaana Wallengr.

Hesperia secessus Trim. 



A species not uncommon on the plateau, especially in the Lake

 type from India.

A single specimen from the high plateau between the Lofu 

 river and Lake Tanganyika, viii., and another near the mouth of 

 the Chambezi river, x.
