this as identical with the shattered insect taken a month previously, 

 or as a second form of the female of those obtained in the pre- 

 ceding November : not having the specimens mounted, it is quite 

 likely that this yellow female was mistaken for a form of B. mesen- 

 tina, which certainly is a very " familiar form " all over Africa, 

 B. zochalia being far less abundant and with a considerably more 

 restricted range.

Of the first female Mr. Crawshay says : — " I am inclined to think 

 this is an insect altogether new to me. Yellowish-white barley- 

 corn-shaped ova." In this belief I think he is correct, although he 

 obtained the male of it at Maranga. The species occurs not un- 

 commonly at Zomba, so that it is strange that Mr. Crawshay should 

 not have come across it in Nyasaland : I am not sure that he did 

 not obtain a female at Lake Mweru.

Of the males Mr. Crawshay writes : — " I took this butterfly, I 

 think, on the Tana Biver about 15 months ago. Here it is not 

 plentiful, at any rate as yet, for to-day I have seen only three 

 amongst a great crowd of other ' Whites ' feasting on the mud, all 

 which three I took without any difficulty." Of the single female 

 he says : — " I do not think I have seen this insect before to-day 

 and then only the one specimen." One female with a (intermediate 

 rather than dry) male was secured on the Muthambi Biver.
