VARIOUS FORMS COURT EACH OTHER 259 



more illuminated at Sesse than Damba. I never thought 

 that I should get such evidence of the effect of a model 

 on its mimic, ... It is very important that the Wiggins 

 Pseudacraea mimics come from several localities near 

 Entebbe and yet never approach your island forms in 

 being intermediate, or resemble their proportions to each 

 other or to the models." 



I began to try to obtain ova from captured females 

 placed in a box in the ft>rest, but although I knew the 

 genus of tree on which they would probably oviposit 

 {Chrysophyllum, Sapotaceae), it was some time before I 

 discovered it in the forest. It may be said here that 

 Miss Fountaine has published ^ beautifully coloured draw- 

 ings of the early stages of the form imitator, which is the 

 only representative in Natal. 



But breeding this form has thrown no light on its 

 genesis, or on the other forms. For, since there is only 

 one Planema to act as a model, imitator appears to have 

 become more fixed than the forms of hobleyi in Uganda, 

 and varies very little. 



Meanwhile, I had often seen the various forms in 

 Uganda flirting with each other in the manner character- 

 istic of male and female of the same species. The follow- 

 ing letter to Professor Poulton is quoted from the Proc. 

 Ent. Soc, June 5, 1912, p. Ixxxv : "I have already told 

 you that I have seen male hobleyi flirting with female 

 terra and vice versa, both hovering flutteringly in the 

 air. Since then I have seen a male obscura paying court 

 to a female terra in the same way. This makes the 

 observations complete. ... So far I have not succeeded 

 in getting eggs, though I have kept four females full 

 of ova : three have died without result, the fourth I 

 have had for a week and it is still living, though it has 

 hardly any wings left." 



However, prolonged observation in the forests at
