darker, the black markings being similar to those of the typical female. Secondaries 

 entirely deep chrome-yellow and showing an additional bright orange streak along 

 the sub-median nervure : the other dark markings do not differ from those of the

A third form of the female is similar to the one above described, but is white 

 suffused with yellow ; the sub-apical row of yellow spots on the primaries is 

 sprinkled with red, while there are three purple spots representing the lower row of 

 markings. 



Underside. — Central area of primaries white, the base, apex and hind-margin 

 greenish yellow, all the black markings well pronounced. Secondaries with the discal 

 area and hind margin pale yellow, the costal margin, basal area, discoidal cell and 

 sub-median nervure strongly suffused with streaks of bright orange. Expanse 2 "4 

 inches. {Spec, ex Henga, 3200 feet, January 22, 1895; B. Crawshai/ ; Mus. Brit.) 



Dry-season form of male. — White with no grey shading near the base, and 

 differing in havuig the black border, which encloses the iridescent purple patch on 

 the primaries much narrower, the apical margin suffused with grey. Secondaries 

 without any nervular lines or terminal spots. 



Underside. — Central area white, apex pinkish-buS", the black discoidal spot very 

 minute. Secondaries entirely pinkish-buff, with the costal orange streak paler ; the 

 costal margin and the basal area waved with fine vermiculations of dusky brown 

 which extend along the sub-median nervure to the anal angle; the usual dusky 

 transverse discal baud nearly obsolete. Expanse 27 inches. {Spec, ex Loangwa 

 Valley Pass, Nyasa Land, 4090 /ee^, August 28, 1895; B. Crawsliay ; Mus. Brit.) 



Dry-season form of female. — Agrees with the " wet-season " female m colour 

 and markings, but the black on the apical area and hind margin of the primaries is 

 more restricted, and shows a distinct grey shading at the extreme edge as in the 

 male ; the sub-apical row of spots on the apex is white sprinkled with crimson, the 

 three lower spots bright crimson. Secondaries have the black nervular spots on 

 the hind margin nearly obsolete and the grey shading at the base only faintly 

 indicated. 



Underside. — Primaries white, the apex sandy colour darkly speckled, the post- 

 median band of black spots somewhat smaller, those situated above the sub-median 

 nervure and first median nervule nearly obsolete. Secondaries entirely sandy colour, 

 dusted all over with greyish brown, the transverse band, composed of brownish 

 spots, not pronounced as in the " wet-season " forms ; the orange costal streak also 

 paler in colour. Expanse 2-2 inches. {Spec, ex Makaya District, November 1890 ;
