LlMNAS CHRYSIPPUS L. 



A common insect everywhere but prefers open country and 

 avoids very dense forest. The specimens are mostly of the type 

 form with occasional individuals tending to var. alcippus Cram. 

 I saw one specimen of the dorippus Klug form in the mid- 

 Ohambezi valley in May, and found it not uncommon a few 

 miles above the mouth of the Lofu river, near Lake Tanganyika, 

 but did not meet with it to the south of these localities. 



TlRUMALA LIMNIACE PETIVERANA Dbl. & Hew. 



Occurs over the whole area except in the Zambezi valley, but 

 is nowhere a common insect so far as my experience goes. 



Amauris niavius L. 



Sparingly in dense forest on the Lualaba river, iv. and v., and 

 in similar localities on the Kalungwisi river, ix.
