The exceedingly fine and complete collection of British 

 East African butterflies (1905-12), presented by the captor, 

 Rev. K. St. Aubyn Rogers, M.A., Wadham College, has now 

 been catalogued and incorporated. The generous donor gave 

 extremely kind and efficient assistance in this task, by himself 

 undertaking the arrangement of the African Lycacnidae, during 

 a visit to Oxford in the summer of 1912. The immense 

 extent of the gift may be inferred from a glance at the 

 following pages, where the collection, although catalogued 

 under the separate years, is acknowledged as a whole. The 

 University Collection now possesses, in consequence of this 

 great gift, one of the finest, if not the finest series of British 

 East African butterflies in any museum. All possess the 

 most excellent data of time and place. A small but valuable 

 collection of moths and of beetles, as well as many specimens 

 of great bionomic interest, are also included. 



The localities are arranged in the following order : — (1) The 

 coast district in the neighbourhood of Rabai, 14 miles N.W. 

 of Mombasa ; (2) The Uganda Railway as far as Voi and then 

 diverging to the Hills of Taita, Taveta, and Kilimanjaro ; 

 (3) The Uganda Railway W. from Voi, thus reaching the 

 Nairobi, Fort Hall, and Kenia districts. 



Rabai (about 700 ft.), 14 miles N.W. of Mombasa.
