notes on Butterflies from the Victoria Nyanza. 219 
All the members of a small group of peculiar interest 
were captured by Mr. Wiggins at Entebbe on the north- 
west shore of the Lake within a few days of each other. 
The dull-coloured Planema paragea, Grose-Smith, 1 f 
(April 5, 1903) and 1 (April 9, 1903) is the model of 
the group. It is mimicked by two species both recently 
described,* viz. :— 
Pseudacreva obscura, 1,12 (April 5, 1903), of which the 
is the better mimic. 
Papilio gallienus peculiaris,t 1 2 (April 6, 1903). 
This species is remarkable for its small size and sombre 
colour relieved by pale cream-coloured markings, thus 
closely resembling the model. 
Remarkable evidence of the coimcidence of mimetic 
forms in time and space is here afforded by the fact that 
three such widely-separated species, all very closely 
resembling one another, should all have been captured on 
the same spot and on nearly the same date. 
The plentiful Acrwa sotikensis, Sharpe (87), has only 
one mimic in the collection but that a remarkable one, 
viz. Mimacrxa poultoni, mihi (3). The resemblance on 
both surfaces is extremely close. The group of spots on 
the underside at the base of the hind wing and the 
characteristically marked hind margin of the Acrwva is 
faithfully represented on the Lyczenid. 
A very large number of small orange-red and_ black 
Acreas, forming a synaposematic group occur in the 
collection comprising :— 
Acrea vinidia, Hew. (1287). 
alicia, Sharpe (147). 
wour, Grose-Smith (5). 
” 
” 
And the more outlying A. serena, Fabr. (1451). 
They are mimicked by the Lycenid Telipna carnuta, 
Hew. (2). 
A similar group is that in which the common Pardopsis 
* loc. cit. pp. 333 and 342. 
+ N.B.—Dr. Karl Jordan, of the Tring Museum, informs me that 
this species may not improbably prove to be a mimetic form of 
the ? of cynorta, Fabr., the ¢ ¢ (not represented in the Wiggins 
coll.) being hardly distinguishable from that species.
