1040 — 
Mr. NEAVE's two papers owed their existence to the generosity 
and energy of my friend Dr. C. A. WIGGINS of Entebbe, and the 
present paper is equally due to his kindness. Dr. WIGGINS has, in 
part by his own efforts, in part by the employment of native 
collectors, obtained collections of Forest Butterflies on a large 
number of dates. These collections are ample enough to enable the 
enquirer to judge of the numerical relationships. Special care was 
taken to eliminate, as far as possible, the natural preferences of the 
collector for one species rather than another. Dr. WIGGINS’ own 
captures are clearly distinguished from those of the natives in the 
columns of the following tables. Upon Dr. WIGGINS has fallen the 
severe labour of recording the data of time and place with precision, 
and packing the collections so that no mistake in interpretation 
could be made. 
My assistants in the Hope Department of the Oxford 
University Museum, and Mr. A. CANT, who has given most 
efficient help in the « setting », have worked hard and success- 
fully to render the data permanent and these great collections 
available for the student. I wish particularly to thank my friend 
Mr. H. ELTRINGHAM for very much kind help in unpacking, 
determining and recording the collections, and Dr. KARL JORDAN 
for his valuable opinion on some of the most difficult of the species. 
The present paper is only an instalment; for Dr. WIGGINS has 
most kindly promised to continue his important work until the 
conclusions derived from material collected during certain months 
have been tested by collections made in the same period of 
another year. But I have not wished to withhold the whole of 
the results until his work is complete, and I have chosen the First 
International Entomological Congress as the occasion on which to 
bring forward this preliminary statement. 
The three Planema-centred Combinations, which ferm the sub- 
ject of this paper, are by no means the only mimetic associations in 
the forests near Entebbe. Thus the species of the Danaine genera
