EXTRACTS FROM THE PROCEEDINGS 
OF THE 
ENTOMOLOGICAL SOCIETY OF LONDON 
(DrceMBER 247TH, 1903). 
October 7th, 1903. 
Mr. Ronanp Trimen, F.R.S., exhibited some cases of mimi- 
ery between butterflies inhabiting the Kavirondo-Nandi 
district of the Uganda British Protectorate, particularly that 
in which Planema poggei, Dewitz, is imitated by an apparent 
variety of Psewducrxa kiinowii, Dewitz, and also by a hitherto 
undescribed form of the polymorphic 9 Papilio merope, Cram. 
He mentioned that both Planema poggei and Pseudacrea 
kiinowti were described and figured by Dewitz in 1879 from 
single specimens taken by Dr. Pogge in Angola, and added 
the interesting fact that the only other example of the unde- 
seribed mimicking form of the 2 Papilio merope known to 
him—in the Hope Department of the Oxford University 
Museum—is ticketed ‘“‘ Angola; Rogers, 1873.” Now, all 
three butterflies had been found as far to the eastward as 
Uganda, the Planema apparently not uncommonly, but its 
two mimickers very rarely indeed, by Mr. C. W. Hobley, of 
Jisumu. 
This case was of special interest because it was the first brought 
to notice of the mimicry of one of the Acrxinx by a 2 Papilio 
of the merope-group of the genus, members of the Danaine 
genera Amauris and Danais being the known models copied. 
Yet it must not be forgotten that the extremely rare form 
of ° of the Abyssinian Pap. antinorii, Oberthiir, named 
Ruspine by Kheil, mimicked the moth Aletis helcita more 
closely than it did Danais chrysippus ; and the large number 
of variations in various directions from the principal and 
pronounced mimicking forms of the merope-group indicated
