a. A Plancma-Acnea-centred Combination. 



Both at Taveta and Rabai the form of Planema aganice, 

 Hew., which has been named by Dr. Butler Planema 

 montana, is common. This form is characterised by the 

 rich fulvous colouring of the male, the female coming 

 into the black and Avhite combination centred round 

 Amauris niavius f. dominicanns, as referred to on pp. 507, 

 508. Associated with this species, but perhaps always less 

 numerous, I took a form of Acrma esehria, Hew., called 

 by Miss Sharpe Acr/va jacJcsoni, which bears a strong 

 resemblance to it, especially on the wing, where the details 

 of the black and fulvous colouring would not be prominent. 

 This form is considerably smaller than Plamema aganice, 

 but they are so much alike that it was some time before 

 I realised that they were not the same species. 



[Eahai, July 1, 1908. 



I once took a Pseudathyma (possibly a new species), 

 now in the British Museum, which quite deceived me on 

 the wing. I took it for A. esehria until I had it in the 

 net] 



[Plymouth, Jan. 2, 1908. 



I may also refer to the obvious resemblance of a male 

 Pscudacraia * to the males of these two Acrgeines [especially 

 the rich fulvous-marked Planema montana], although I 

 have not myself taken this mimic. The single specimen 

 (from Shimba) in the collection I sent to Oxford, was 

 given to me. This Pscudacriea from Shimba is probably 

 the male of the form allied to P. hirce, mentioned on 

 p. 508.]

My kind friend the author has presented to the Hope 

 Department the following specimens of Planema aganice f. 

 montana together with the Acrseas resembling it : — ■ 



Dabida (May 25— June 16, 1904) : 2 ^ and 3 ? of 

 montana, all normal except one female with a pale ochreous 

 instead of a white patch on the hind- wing. There are no 

 specimens of A. esehria from this locality.
