shade on the basal portion of the primaries and on the central area of the secondaries, 

 the latter having a tiny black spot at the end of the cell. The primaries show 

 several distinct black spots, a large one between the sub-median nervure and the 

 first median norvule ; a second smaller spot occurs nearer the hind margin, between 

 the first and second median nervules ; above this spot is a band of dusky green 

 shading, extending to the costal margin and corresponding with the inner black band 

 on the upper surface. The end of the discoidal cell is outlined with black. 



Female.— While reproducing the markings of the male, the female differs from 

 that sex considerably in the extent of the mottlings and in general colour. Thus 

 tlie orange is confined to the basal area, and the ground colour of the apical portion 

 of the wins: is lemon-yellow ; hence the spots which intersect the dai'k apical portion 

 of the wings are lemon-yellow instead of being salmon-buff" as in the male, though, 

 in the secondaries, there is a slight tiiit of orange perceptible on the inner band. 

 The blackish aspect of the wings is not so pronounced in the female, but is of a 

 browner shade, and the blackish border of the secondaries is narrower ; while the 

 sub-terminal row of pale spots is distinctly larger and more prominent than in the 

 other sex. 



Underside. — Much more coarsely marked, and with the orange confined to a patch 

 on the basal third of the wings. The markings which are faintly evident on the 

 underside of the male are strongly emphasised in the female, being darker and of a 

 reddish-brown colour. This is especially the case on the secondaries, where the 

 dusky markings ai"e distinctly indicated, so that there is a narrow but distinct sub- 

 terminal line of reddish-brown traversing the wing. Expanse 1 '0 inch. 



Among the females there is an occasional tendency to a white form, wherein the 

 pale markings of the wings are almost yellowish-white. Great variation in size is 

 evident in a series, and I have examined some unusually large specimens from 

 Mombasa and Kilimanjaro (see plate la, figs. 2 and 2«).
