a. A Plancma-Acrxa-ccntrccl 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 white combination centred round 

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

 508. Associated with this species, but perhaps always less 

 numerous, I took a form of Acraia esebria, Hew., called 

 by Miss Sharpe Acrica 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 Planema aganice, 

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

 I realised that they were not the same species. 



[Rahai, 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. esebria until I had it in the 

 net.] 



[Phjmouth, Jan. 2, 1908. 



I may also refer to the obvious resemblance of a male 

 Pseudacriea* to the males of these two Acrseines [especially 

 the rich fulvous-marked Plancnuc 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 Pseudacrssa from Shimba is probably 

 the male of the form allied to P. hvrce, 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 paleochreous 

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

 specimens of A. esebria from this locality.
