1. Tlie Primary Danaine Models. 



In Kikuyu Amauris alhimaculata, Butl., is the dominant 

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

 manjaro Amattris echeria, Stoll., is also commonly found, 

 as is usually the case where A. alhimaculata occurs. It is 

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

 must have been comparatively rare in the under-mentioned 

 localities at the times when I visited them. 



2. NympJmli-Jie Mimics. 



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

 British East African forms of Pseudacrsea lucretia seem to 

 fall more properly into the group of which A. ocJilea 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 Amauris echeria. and alhimac7ilata. 



A form of the female Atcrica galcnc 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 echeria-liko. 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 Danainee, it was at once evident that a 

 form of Amauris cgialea, Cram., with an oehreous hind-wing patch, 

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