$ White, with (jlittcring-vioUt cqncal patcJi edged on loth sides ivitli 

 blackish. Fore-wing : base rather widely and closely sprinkled with 

 blackish scales, especially along and near inner margin ; costa also 

 similarly sprinkled but becoming black-edged before middle ; apical 

 violet forming a moderately wide band, lessening in width towards its 

 extremities (especially inferiorly), from second subcostal to between 

 third and second median nervules, and divided by slender black crossing 

 nervules into five unequal parts (besides a minute sixth part between 

 third and fourth subcostal nervules) ; inner black edge of violet mode- 

 rately broad, complete throughout, but rather diffused inwardly, extend- 

 ing from costa a little beyond middle to a point at extremity of first 

 median nervule on hind-margin ; outer edge broader, especially at 

 apex, and (except on nervules) strongly clouded with pale grey, the 

 dark indentations of the violet on nervules very slight ; a small, thin, 

 elongate, slightly curved terminal disco-cellular black spot ; ueuration 

 only black beyond middle, except submedian nervure, which is heavily 

 marked in black from considerably before middle. Hirid-iving : neura- 

 tion conspicuously black-marked throughout ; in some specimens the 

 black is barely or slightly thickened at extremity of nervules, but in 

 most it is developed into a conspicuous series of hind-marginal spots 

 with diffiised edges ; fold between median nervure and its first nervule 

 and submedian nervure marked with a distinct black line, and some 

 blackish irroration over the same inter-nervular space and lower basal 

 part of discoidal cell. Under side. — IVhite throughout, or ivith a very 

 slight tinge of pale yelloivish or p)ale pinhish-creamy over hind-iDing and 

 apical area of fore-wing. Fore-wing : disco-cellular spot distinct ; a 

 veiy faint indication of the position of the violet patch of upper side. 

 Hind-wing : costa edged narrowly with orange-yellow for a little dis- 

 tance from base (rarely as far as middle or a little beyond it) ; a termi- 

 nal disco-cellular black spot, smaller than that in fore-wing ; beyond 

 middle a blackish mark on costa is the first and usually the most dis- 

 tinct trace remaining of a discal macular ray, normally angulated on 

 third median nervule, — but its course seldom continuously marked even 

 so far, and beyond that point never indicated except by two widely 

 separated, small, often indistinct spots. 



$ IFhitc {rarely more or less yelloiv) ; apieal patch of fore-wing much 

 broader than in $, orange-red, spotted and broadly bordered with black. 

 Fore-wing : basal clouding much denser, darker, and superiorly much 

 broader than in ^ ; disco-cellular spot much larger and rounder ; 

 between first median nervule and submedian nervure a large quadrate 

 discal black spot, sometimes enlarged aud confluent inwardly with
