1. The Primary Danaine Models. 



In Kikuyu Amauris albimaculata, Butl., is the dominant 

 species and all my specimens belong to it, whereas on Kili- 

 manjaro Amauris echxria, Stoll., is also commonly found, 

 as is usually the case Avhere A. albimaculata occurs. It is 

 quite probable that A. echeria exists in Kikuyu, but it 

 must have been comparatively rare in the under-mentioned 

 localities at the times when I visited them. 



2. Nymijhalijie Mimics. 



I have never met with Eurcdia mima, Trim. ; * and the 

 British East African forms of Pseudacnea liLcretia seem to 

 fall more properly into the group of which A. ochlea is the 

 centre. Certain varieties of the female in the closely allied 

 sub-species tarquinia. from Natal are, on the other hand, 

 excellent mimics of Ainauris echeria and albimacidata. 



A form of the female Aterica galene appears to be a 

 well-marked member of this group, while the male is 

 a more outlying member. Although probably always 

 mimetic this species is very independent of the local 



* When glancing over the splendid collection of Congo butterflies 

 in the Brussels Museum, under the kind direction of Monsieur 

 Severin, I noticed several ec/iecia-like specimens of Euralia dinarcha. 

 Hew. — the var. bartteloti — Grose-Smith, from Beni Bendi, in the 

 central part of the State. I was astonished at this because it was 

 fairly certain that the well-known models did not exist in that 

 locality. Turning to the Danaince, it was at once evident that a 

 form of Aiivxtiris egialed, Cram., with an ochreous hind-wing patch, 

 occurred at the same locality and supplied the model. E. B. P.
