^ White, with rather small dull orange-yellow apical patch hlacldsh- 
hordered loth internally and externally. Fore-iving : costa witli 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-wing ; a hind-marginal 
series of six moderate-sized or small separate nervular blackish spots. 
Undee side. — Hind-iving and apical patch of fore-wing creamy-ivhite, 
finely irrorated with fuscous. Fore-ioing : terminal disco-cellular dot 
larger, well defined ; a very faint indication of apical orange and its 
dark inner border. Hind-iuing : 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. 
$ Apical orange-yelloio patch narroio, much curved, six-partite {un- 
equally) hy very fine Uach nervules, much more Iroaclly Uachish-hordered 
internally and externally tlian in $ ; in each wing an imperfect longi- 
tudinal blackish stripe, and in hind-wing cdso an irregular elbowed disced 
Uackish ray. Fore-iuing : basal area finely irrorated with blackish (in 
one example also tinged with sulphur-yellow) ; inner-marginal blackish 
broad, somewhat greyish, and diffused, except at its extremity not far 
beyond middle (where it emits a faint thin upward ray) joining 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, except 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 fate 
creamy -yellowish or dull creamy, very finely irrorated ivith fuscous. 
Fore-iuing : basal area faintly suffused with sulphur-yellow, but without
