The specimens include i Salamis cacta, i Pseiidacraea albo-

 The data are admirable and the specimens of much value to 

 the Department. 



Additions to the Collections in 1906. 



One hundred and eighty-two butterflies, collected in N.E. 

 and N.W. Rhodesia (1904-5) by S. A. Neave, Esq., M.A., 

 B.Sc, Magdalen College, and presented by him and the 

 British South African Company, have been added to the 

 collection. The series includes 5 Acraea leucopyge, i A. viola- 

 rtini n^nbrata^ i Papilio mackiiuioni benguelae, and male and 

 female co-types of a new Sarangesa (to be described as vS. nox 

 in Mr. Neave's forthcoming paper in the Proc. Zool. Soc. 

 Lond.). The addition of these specimens, of which half have 

 been catalogued as permanent accessions, completes the in- 

 corporation of the earlier collection of butterflies made by this 

 generous friend of the Department. Some account of the 

 collection (of which 1,278 specimens were catalogued) and of 

 the parts of Africa which it represents was published in last 

 year's Report. 



Two very interesting sets of mimetic butterflies and their 

 models, presented by the captor, Rev. K. St. Aubyn Rogers, 

 M.A., F.E.S., Wadham College, have been incorporated in 

 the bionomic collection. 



The first, consisting of 21 specimens captured on the slopes 

 of Kilimanjaro (Jan. 5-16, 1906), contains 5 Amaiiris albima- 

 adata [Danaifiae), two of its Papilionine mimics (2 cenea 

 females of P. dardajitis tibtdlns and 3 males of P. echerioidcs, 

 of which the female is a mimic), and several specimens of its 

 Acraeine mimics A.johnstoni ?iv\d fallax. Also the dorippiis
