$ . White ; apical patch bright-red, inclining to orange, hut 

 </lossed with a rosy lustre. Fore-wing: apical red divided into 

 six by the dark nervules crossing it, margined outwardly by a 

 narrow black stripe sharply indenting the red by radiating upon 

 the nervules, inwardly by a thin, blackish, ill-defined streak ; 

 costa edged with blackish ; a distinct, round, black dot at 

 extremity of discoidal cell ; a broad, blackish band along 

 inner-margin, to beyond middle, w^here it very slightly curves 

 upwards and ends abruptly. Hind-iving : base greyish ; a 

 blackish band along costa adjoining that on inner-margin of 

 fcre-wing, and abruptly ending immediately below where the 

 latter ends ; on hind-margin, at extremities of nervules, a 

 row of black spots, variable in size, and inclining to form a 

 continuous band, generally diminishing to anal angle. Un- 

 der-side. — Fore-wing : apical marking soft creamy-yellow, 

 inwardly pale orange ; disco-cellular spot distinct ; inner- 

 marginal band pale-greyish from base, ending in a darker 

 spot. Hind-wing : pale creamy-ochreous, or creamy-reddish, 

 more or less irrorated with grey atoms ; costa, from base to 

 beyond middle, edged with bright orange-yellow ; disco- 

 cellular spot orange, outwardly black-dotted ; a scarcely 

 perceivable greyish tint along costa indicates the position of 

 the costal band, the extremity of which is always shown by 

 a greyish mark. 



? . Very variable in size, frequently smaller than $ . 

 Fore-wing : red at apex much narrower than in $ , of a more 

 orange tint, and ivithout rosy lustre, its black borders much 

 wider, especially the inner one (which latter is, however, 

 often intersected by the red, and occasionally with faint red- 

 dish colouring on its inner-side) ; spot at extremity of 

 discoidal cell larger than in $ ; inner-marginal blackish band 

 broader and darker, its upper edge not clearly, defined, but 

 gradually shading off in discoidal cell to near costa, and its 

 outer extremity often united to inner black border of apical 

 marking, on first median nervule, by a narrow, upward, 

 blackish streak. Hind-iving : grey at base, and costal band, 

 similar to the same in $ , but broader and darker ; from ex- 

 tremity of band, a more or less marked blackish streak 

 extends almost to middle of hind-margin, where it meets the 

 row of black spots (larger and more contiguous than in ^ ), 

 and from whence it turns off at right angles to beyond
