PSEUDACRAEA EURYTUS 



predominant form of Psevdacraea is not the same on 

 each island. 



At each locality the predominant Pseudacraea is that 

 which mimics the species of Planema that is most 

 numerous in that locality, and this is further borne out 

 by the collection from Kakindu on the mainland to the 

 west of the lake. 



From the above table it is seen that while on Kome 

 the model of type of colouring IV {Planema tellus) was 

 most abundant, on Ngamba the species that predom- 

 inated were of types I and II, and on each island the 

 proportions of the forms of Pseudacraea are according 

 to the prevailing type of models. At Kakindu, again, 

 type IV predominated in the models, and all the Pseud- 

 acraeas save one were of type IV. The islands mentioned 

 are so close together that it would be absurd to attempt 

 to explain the differences in the Pseudacraea fauna by
