^ IFIiite, with rather sinall dull orange-yellow apical imtch Uaclcish- 

 hordcred hath internally and externally. Fore-wing : costa with a very 

 fine linear black edging ; base narrowly and very sparsely powdered 

 with blackish ; a well-defined terminal disco-cellular black dot ; apical 

 orange bordered internally rather widely with blackish (which in type 

 is even throughout, but in a second specimen becomes rather thin and 

 diffused between third and second median nervules), and externally by 

 narrower border, piercing the orange to some depth on nervules, and 

 itself pierced by four or five inter-nervular acuminate rays of the orange, 

 and ending about second median nervule. Hind-wing : sparse basal 

 powdering rather more extended than in fore-win^^ ; a hind-marginal 

 series of six moderate-sized or small separate nervular blackish spots. 

 Under side. — Rind-wing and apiccd patch of fore-wing creamy-iohite, 

 finely irrorated with fuscous. Fore-wing : terminal disco-cellular dot 

 larger, well defined ; a very faint indication of apical orange and its 

 dark inner border. Ilind-wing : costa edged with orange-yellow for a 

 little distance from base ; a terminal disco-cellular black dot, bounded 

 internally by a small bright orange spot ; nervular hind-marginal black 

 dots very minute. 



$ Apiccd orange-yclloio patch narrow, much curved, six-p)artite (un- 

 equcdhj) by very fine Uach nervules, much more hroadly hlachish-hordercd 

 interncdly and extcrncdly than in $ ; in each wing an imperfect longi- 

 tudincd Uackish stripe, and in hind-iuing cdso an irrccjular clhoiced disced 

 Uackish ray. Fore-ioing : basal area finely irrorated with blackish (in 

 one example also tinged with sulphur-yellow) ; inner-marginal blackish 

 broad, somewhat greyish, and diflused, except at its extremity not far 

 beyond middle (where it emits a faint thin upward ray) joinino- inner 

 border of apical patch ; terminal disco-cellular spot large, sub-ovate ; 

 outer border of apical patch broad, not deeply indenting the orange, 

 and not pierced by the latter, ending abruptly on or just below first 

 median nervule ; the two borders unite rather broadly on second median 

 nervule. Hind-wing: basal irroration sparse, but widely extended 

 inferiorly; costal stripe broad, rather faint, excejot at its abrupt ter- 

 mination ; a small but distinct terminal disco-cellular dot ; discal 

 elbowed ray narrow, irregularly angulated, fainter superiorly, and be- 

 coming obsolete towards inner margin; a rather wide hind-marginal 

 blackish border, continuous from apex to second subcostal nervule 

 (where it is connected with elbow of discal ray), but thence with inter- 

 nervular interruptions and becoming obsolete not far from anal angle. 

 Under side. — Hind-iving and apical patch of fore-wing very pah 

 creamy-yellowish or dull creamy, very finely irrorated icith fuscous. 

 Fore-u-ing : basal area faintly suffused with sulphur-yellow, but without
