390 Mr. Roland Trinien on some hitherto 



tlie Mazoe District, Mashonaland, as far back as 1894 and 

 1895. Among the few specimens received from Mr. 

 Marshall there were several which differed strikingly from 

 typical sccessus in presenting on the underside of the hind- 

 wing a conspicuous creamy-whitish median band and other 

 markings, instead of the very faint ones characteristic of 

 secessns, which are scarcely distinguishable from the pale 

 dull brownish-ochreous ground-colour. I thought that 

 these white-marked individuals represented a very distinct 

 variety or possibly a closely allied species ; and it was not 

 until the year 1905 that my attention was again recalled 

 to them by receiving from Mr. H. L. Feltham and Mr. 

 A. T. Cooke two quite similar but larger examples taken by 

 the latter in the Transvaal. The occurrence of this con- 

 spicuously-banded form so much further southward rather 

 confirmed my impression that it might be distinct from 

 secessus; and Mr. Feltham and Mi*. Cooke kindly promised 

 to endeavour to secure more material towards deciding the 

 question. This endeavour has been successful, and I have 

 received from them thirteen examples (8 ^^, 5 $$) — four 

 taken at Nelspruit, and nine at White River (about 

 eight miles from Nelspruit). All these are of the same 

 conspicuous white marking on the underside of the hind- 

 wing, presenting no variation in the direction of the obscure 

 colouring of typical secessus. Eleven of them bear dates 

 of capture, ranging from October to January ; and the 

 dates of Mr, Marshall's three Mashonaland examples of 

 the same form were respectively October 21 and 30 and 

 November 4. Similarly, in a series of thirteen N. 

 Rhodesian examples collected by Mr. Neave, which are 

 in the Hope Department of the Oxford University 

 Museum,* the only one with the underside of the hind- 

 wings white-banded is dated November, while three with 

 the band much paler than in typical secessus are dated 

 respectively September 18, October 29, and December 1. 

 The remaining riine specimens are dated as captured in 

 July and August, and though varying in depth of tint all 

 present the dull underside colouring of typical secessus; 

 and I have recorded {I.e.) that Mr. Eriksson took the 

 South-Angolan type examples in August 1887. 



The dates given by the several captors appear to indicate 



* I am indebted to my friend, Mr. H. Eltringham, for supplying 

 these dates of capture of Mr. Neave's specimens, which in a rather 

 hurried examination I had omitted to note.
