214 Mr. S. A. Neave : some lionomic 



may be conveniently taken as the same model. They 

 both seem common in nearly every locality except the 

 more exposed and open plains. There were 176 specimens 

 from various localities in the two collections, but Mr. 

 Wiggins speaks of them as his " pet aversion," explaining 

 that they were enormously abundant. The best mimics 

 of these species in the collection are : — - 



Eiiralia mima, Trim. (16), mostly from the west shore of 

 the Lake. 



FcqnUo hoyneycri, Plotz, 86 (^^ and 3 i^ $, of which the 

 latter only are mimetic. 



Papilio dardanics $, f. cenca, StoU. 



This form of the $ did not occur in the Wiggins 

 collection, but there are three specimens in the Harrison 

 coll. from Nyangori, near the north-east shore of the 

 Lake. 



As Professor Poult on has pointed out, loc. cit. p. 48-5, 

 there is a very remarkable secondary resemblance between 

 these mimics. The $ of P. homeyeri, Avhich does not occur 

 in the group mentioned by him, further bears this out, 

 having an actually closer resemblance to Euralia mima 

 than to Amatiris ccheria itself. There are also in the collec- 

 tion some other less good mimics of A. echeria lying on 

 the outskirts of the group, comprising :■ — Hypolimnas 

 dinarcha, Hew., the forms of Pseudacr.va lucretia, and a 

 number of the smaller Acr/vas such as A. servona, Godm., 

 A.circeis, Dewitz, J.. o?'m5, Sharpe, and its form alhimaculata, 

 and especially A. johnstoni, f. Jlavcsccns. N'eptis woodivardi, 

 Sharpe, also comes into the same group. 



For a full account of the convergence between many 

 species o^ Acrxa, including most of the above-mentioned, 

 and species of Amauris, see Professor Poulton's paper, read 

 before Section D of the British Association at Toronto, 

 1897.* 



LiMNAS CHRYSIPPUS GrOUP. 



Limnas chri/sip2JUS, L. (842) and Hyiiolimnas misiirpus, 

 L. (160), were abundant in every locality. They were 

 somewhat less numerous in forest districts. 



Acrxa cncedon, L. (442), was alfco very common every- 

 where.
