On Dr. C. A. Wiggins’ Researches on Mimicry 
in the Forest Butterflies of Uganda (1909), 
by EDWARD BAPOULIoN„E.R.S, 
Hope Professor of Zoology in the University of Oxford, Fellow of Jesus College, Oxford. 
The object of the present paper is to investigate the numerical 
and other relations between the models and mimics of three 
interesting associations, each grouped around one or more species 
of the Acræine genus Planema. The whole of the material was 
captured, between May 23rd and August 31st, 1909, in patches of 
native forest within a few miles of Entebbe, Uganda. The examples 
themselves are well known, the most important having been 
described by Mr. S. A. wNEAVE, M. A. B. Se., im) 1904 (1) and 
1906 (2). The instances of mimicry unrecognised at the time of 
Mr. NEAVE’s memoirs have been described by Mr. HARRY 
ELTRINGHAM in his monograph on Mimicry in the Butterflies of 
Africa (Oxford,« Clarendon Press », 1910), where beautiful coloured 
illustrations of nearly every form mentioned in the present paper 
will be found.
