Specific identity of two forms of Charaxes from South 

 Africa. — Professor E. B. Poulton, F.R.S., exhibited a sei-ies 

 of seven Charaxes neanthes and one C. zoolina, all reared by 

 Mr. G. F. Leigh, F.E.S., from the eggs laid by a single female 

 neanthes. He said that, although the evidence as it stood was 

 not entirely convincing, the independent experience of other 

 naturalists rendered it in the highest degree probable that the 

 conclusions suggested by the presence of the single zoolina in 

 the family of neanthes were sound and permanent. Mr. Leigh's 

 account of his interesting discovery was as follows : — 



Charaxes neanthes, Hew. (1854), a form of C. zoolina, West- 

 wood (1850). 



Having in January 1905 bred from the same larvae, or 

 what I took to be the same larvae, both Charaxes zoolina 

 and C. neanthes, although so different, I determined if 

 possible to obtain ova and try to rear them. On 18th May, 

 1908, I followed up a 9 ^- neanthes, and obtained 18 ova, 

 and should have obtained more, but the insect was then 

 captured by a bird. All hatched on the 23rd and 24th May, 

 and I put the larva? on their food-plant, an Acacia, Entada 

 natalensis, but was very unfortunate with them, no less 

 than 9 dying during the 1st and 2nd stages. The leaves 

 fold up at night, but open again in the wild state, but when 

 picked and put in water they do not open : this I believe 

 was the cause of the mortality ; for I was obliged to keep 

 taking the larvae off the old food and putting them on to 

 new. The 9 remaining larvre throve and 8 became pupae. 

 One larva I preserved, and have sent with the insects, as 

 also the empty pupa-cases. The C. zoolina, a female, was 

 the 3rd to emerge, and I give full pai'ticulars of the emergence 

 from pupa;. In January next I will breed again from C. 

 zoolina 9 , a^s this form is then more plentiful than in
