glance, tbe lower lobe of the clasper being produced npwards into a broad black 

 triaugnlar tooth, while the corresponding lobe of antilope is ver)' short and obtnse ; 

 the upper process of the clasper as well as the other parts of the copulatory 

 ajjpeudages are also different in the two insects. lu the ? of cuama (= trimeni) 

 the eighth abdominal sternite is smooth and bears at the base a large vaginal 

 tubercle, which is slight!}- sinuate at the apex. The eighth sternite of the ? of 

 antilope (= siinia) is densely scaled, subcarinate mesially, and has only the 

 rudiment of a vaginal tubercle at the base. P. cuama appears to be confined to 

 the eastern side of the Continent ; we have it from Nyassaland, German and British 

 East Africa.

In this species again there are two conspicuously different forms, hitherto 

 considered to be distinct species, except by some of the old writers. Cramer's 

 leotiice is the cryptic form and pclarga the " wet phase " of the same species. 

 The ? of f. leodice has the band of the upperside of the wings more or less 

 e.xtendedly shaded with blue. In the f. pelarga the sexes are nearly similar to 

 each other in colour, the band of the c? being as a rule paler than that of the ? . 

 P. jielarga occurs from the Senegal to Angola, its range extending eastwards to 

 Uganda and Abyssinia. 



0. Neumann procured two c?(? of f. leodice at KoUu-Kilbe, Schoa, 6. x. 00. 

 In one of them the band of the forewing is narrow and is interrupted behind R' ; 

 on the underside the basal half of the wings and the distal marginal area are shaded 

 with bluish white, contrasting strongly with a tawny olive elongate-triangular 

 discal space. 



Closely allied with P. pelarga is an essentially East African insect which we 

 possess from British and German East Africa, Nyassaland, and Angola in two 

 forms corresponding to f. pelarga and f. leodice of P. pelarga. This is

In P. actia f. actia both sexes have the band on the upperside of the wings 

 more or less shaded with bine. The " wet " form has apparently escaped being 

 named, being generally considered to be pelarga. This " wet " form, for which we 

 propose the name 



furcata {Igpe: i from Dar-es-Salaam), 



is distinguished by the postdiscal costal branch of the baud of the upjierside of the 

 forewing being better expressed than in /'. pelarga f. pelarga, this postdiscal 

 branch being, especially in the ? of fifrrafa, clearly marked. Moreover, the black 

 dots within the band are less close to the distal edge of the band, the hluisli-white 

 bars near the distal margin on the upperside of the wings are longer, and the 

 distal marginal area of the underside is deeper black. In the ? the band of
