I agree with Prof. Aurivillius that the characters which dis- 

 tinguish this form from typical B. acheloia are seen to be variable 

 when sufficient specimens are obtained, and therefore its distinct- 

 ness as a species cannot be maintained ; the extreme development 

 of this form seems to be reached in Somali-land.

Kampala and Uganda. 



An extremely variable species, sometimes very heavily banded, 

 but often almost as lightly as in the closely allied Madagascar 

 form C. elegans ; indeed, 1 fully expect to see these two supposed 

 species completely linked by transitional varieties, just as, in the 

 New-World genus Helicopis, the palest and darkest types of 

 H. cupiclo grade one into the other. 



42. Aegtnnis excelsioe, sp. n. (Plate XLII. fig. 4.) 



(S . Nearly allied to A. hanningtonii ' (PI. XLII. fig. 3), from 

 which it differs as follows : — Outer margin of primaries convex; 

 colouring above deep tawny ; outer border slightly narrower, with 

 its inner edge undulated and separated from the submarginal 

 series of black spots, which are also smaller : under surface with 

 the primaries orange-tawny, excepting the apical area, which is dull 

 creamy yellowish clouded with green ; ground-colour of secondaries 

 dull creamy yellowish, clouded with green ; silver markings rather 

 larger and more prominent than in A. hanningtonii ; otherwise 

 precisely similar, the disposition and character of the markings 

 being the same. Expanse of wings 40-42 millim. 



Eemale slightly duller and paler, with the borders less black 

 and the marginal pale spots consequently longer than in the 

 males. Expanse of wings 39 millim. 



Euwenzori, 5600 to 9000 feet. 



Twelve more or less worn examples were obtained : Mr. Scott 

 Elliot has a note that it " fertilizes the violet ( Viola abyssinica)." 

 There can be no doubt that this mountain form and that of
