^ . Pure white, with very brilliant blue-shot violet-lake apical 

 patch. Fore-wing : a linear, black, disco-cellular dot ; costa white, 

 or very faintly grqy-dusted nearly to middle, where the blackish 

 edging of the apical patch commences ; apical patch composed of 

 six elongate stripes (defined by the more or less strongly-marked 

 dark nervules), and lying between the 2nd subcostal and 2nd 

 median nervules, very narrowly and faintly edged with blackish 

 internally, narrowly along costa to apex, more widely from apex 

 along hind-margin as far as third median nervule (slightly indenting 

 the violet on each nervule) ; median nervules usually blackish in 

 their central portion, submedian nervure always so ; base very 

 slightly dusted with faint greyish. Hind-iving : usually spotless, 

 occasionally with a hind-marginal row of small blackish spots, one 

 at extremity of each nervule; 2nd subcostal and discoidal nervules 

 often blackish near their origin ; base very slightly grey- dusted, 

 the irrorations often scarcely perceptible. Underside. — White, 

 the hind-wing very faintly tinged with yellowish, apical patch pink- 

 ish-grey. Fore-wing : disco-cellular spot always present; occa- 

 sionally a faint row of four or five fuscous spots about middle 

 of apical patch. Hind-wing : costa more or less brightly edged 

 with yellow from base to about middle ; a minute disco-cellular 

 dot, usually edged superiorly with yellow ; rarely a very indis- 

 tinct transverse row of five greyish spots from costa; extremities 

 of nervules rarely marked with greyish. 



$ . White, with no blackish nervules ; apical patch of the same 

 colour as in $ , but with a less brilliant blue gloss (in one spe- 

 cimen this is scarcely inferior in brilliancy), and divided down its 

 centre by a macular black band, which sometimes almost oblite- 

 rates the inner portion of the violet, — the blackish edgings broader 

 and darker. Fore-wing : disco-cellular dot well marked, ovate or 

 round; near anal angle two blackish spots, continuous of the row 

 dividing the violet. Hind-wing: blackish hind-marginal spots 

 more usual than in $, but far from common. Bases of both 

 ■wings a little more markedly and widely irrorated. Underside. 

 •^Apex o^ fore-wing and whole of hind-wing dull creamy-ochre- 

 ous, occasionally with a reddish tint, and faintly patched minutely 

 with grey j disco-cellular spots well defined, that of hind-wing
