August, and I also hope to obtain a larger number of ova. 

 All the 8 specimens now sent are midgets, owing to the 

 larvae being starved in July, because, in consequence of 

 ill-health, I was unable to get them fresh food often 

 enough. The times of pupation and of emergence were as 

 follows : — 



I may mention that Mr. E. L. Clark, F.E.S., of Congella, 

 bred 2 zoolina and 4 neanthes in January this year from what 

 he took to be the same larvae. 



G. F. Leigh, F.E.S., 



Dui-ban, Natal. 



Professor Poulton said that he had submitted Mr. 

 Leigh's paper to Mr. G. A. K. Marshall, who had replied as 

 follows : — 



London, Oct. 8, 1908. 



" Leigh's results with Charaxes neanthes are extremely 

 interesting, but I am not at all surprised to hear of them. 

 I have always been struck by the very close relationship 

 of this form to zoolina, and at one time thought they might 

 be seasonal forms one of the other ; but such dates as 1 

 could obtain did not seem to quite agree with that idea." 



Professor Poulton observed that the far more cryptic 

 under surface of neanthes, together with its general colouring, 

 suggested a dry-season form. He had asked Mr. Marshall 

 for his experience of the duration and succession of the Avet 

 and dry seasons in Natal, and his friend had kindly supplied 

 the following account : — 



The early rains begin about mid-August and the wet 

 season proper in mid-September, continuing until mid-March.
