branches, occupying the same position as in the female. 

 In the wet-season female the costa and apex of the fore- 

 wing and the whole of the hind-wing are usually yellowish 

 beneath. The submarginal chain of spots is present on 

 both wings ; the spot on the fore- wing between the second 

 and third median being large and conspicuous, as on the 

 upper surface. Discocellular spots are present on both 

 wings. In the dry season the male may show above little 

 or no trace of dark veining. The dark markings of the 

 female are also much reduced, but the large spot between 

 the second and third median branches is still present and 

 conspicuous on the fore-wing; the hind-wing may be 

 spotless, though there is usually a marginal series of dark 

 spots. A discocellular spot is generally present on the

fore-wing, but not on the hind-wing. Beneath, the male 

 may be spotless but for the large median spot, which per- 

 sists. The female often shows a slight mottling on the 

 hind-wing and apex of the fore-wing, to which the sub- 

 marginal spots are assimilated. This mottling is com- 

 paratively pale, and the powdering specks are usually 

 more sparsely distributed than in most specimens of 

 /'. charina. Discocellular spots are present on both wings, 

 but may be very faint. The clasper in a male from Mom- 

 basa is large, like thai of P. charina; and ends posteriorly 

 in a long spur (fig. 3), still longer than the correspond- 

 ing structure in that subspecies. The clasper of another 

 Mombasa specimen, which corresponds in appearance 

 with Grose Smith and Kirby's P. gerda, is of the same 

 HI in na character, but with a somewhat shorter spine (fig. L6).
