median nervule, afterwards becoming nearly obsolete ; the usual orange basal streak 

 visible on the costal margin. Expanse 2-3 inches. {Spec. ex. Witii, May 1891 ; F. J. 

 Jackson Coll.) 



Female. — Primaries with the apex, hind- and inner-margins, brownish-black, 

 heavily pronounced on the latter ; a black band crossing the apical area enclosing a 

 bright orange patch, this patch being relieved by a post-median row of black spots ; 

 about the centre of the costal margin a broad white band crossing the wings and 

 terminating in an almost ovate spot near the posterior angle, the dark shading at the 

 basal area thickly sprinkled with grey. Secondaries with the central area white ; a 

 broad brownish-black border on the hind-margin strongly dentated on its inner 

 aspect ; costal margin dark ; a narrow dark line crossing the white discal area and so 

 dividing three distinct white spots from the central area ; the base dark and thickly 

 dusted with grey, which extends along the sub-median nervure to the hind-margin. 



Underside. — Central area of the primaries yellowish-white, the apical portion pale 

 orange, shading to a lighter yellow on the extreme edge of the hind-margin; the 

 post-median row of black apical spots well indicated, the dark shading at the base 

 and on the inner margin also visible. Secondaries pale yellow, somewhat lighter in 

 colour on the discal area, the transverse rufous band and orange costal streak well 

 pronounced ; the hind-marginal border dusky yellow. Expanse 2"2 inches. {Sjjec. 

 ex. Witu, May 1891 ; F. J. Jackson.) 



A second form of the female (PI. 18, fig. \d) only differs from the one above 

 described in the absence of the orange apical patch on the primaries, fn this 

 specimen the black apical patch is relieved by three distinct ovate spots of ochre 

 colour; two being nearly obsolete, one near the costal margin, the second situated 

 above the second median nervule. The black hind-marginal border on the secondaries 

 is not so broad. 



Underside. — Differs in having a broad black apical band from the costal margin 

 to the first median nervule on the primaries, the apex and hind-margin being of a 

 deeper yellow. Secondaries yellow with rufous-brown vermiculations, the transverse 

 band strongly marked with the same colour. Expanse 2*2 inches. {Spec. ex. "East 

 Africa"; Mm. Rothschild.) 



Mr. Jackson has in his collection another form of the female which agrees with 

 the second phase above described as regards spots and markings, the apical spots 

 being entirely white instead of ochre-yellow or orange. The underside is much paler 

 and the post-median row of black apical spots on the primaries is distinctly visible ; 

 otherwise the markings agree with those of the " orange " form of the female. 



"Dar-SEASON" Form of Male. — Differs from that of the "wet-season" form in 

 having the black on the apex and hind-margin less strongly marked, the apical
