PIERIN/E. 
rather closely irrorated with blackish ; costa with a linear black edging 
from before middle to end of second subcostal nervule ; at the latter 
point commences the apical hind-marginal blackish border, which is 
narrow, and rather suffused and ill-defined on its inner edge (where it 
forms more or less marked nervular dentations), extending to between 
second and first median nervules ; usually a small blackish mark at 
extremity of first median nervule. Hind-iuing : sometimes without 
marking, but usually with a series of very small, faint, nervular blackish 
marks along hind-margin, of which the first (at extremity of first sub- 
costal nervule) is much longer and more pronounced than the rest. 
Under side. — Eind-wing mid apical border of fore-iuing faintly tinged 
with rather didl cream-colour. Fore-wing : no blackish border ; in dis- 
coidal cell a narrow basal suffusion of chrome-yellow ; some scarcely 
perceptible indications of very small hind-marginal nervular spots. 
Hind-wing : costa from base to a point considerably before middle 
narrowly edged with chrome-yellow ; in some specimens, traces of some 
very small hind-marginal nervular spots, those at extremities of first 
subcostal and second median nervules more apparent than the rest. 
$ Blaclush border of fore-wing very broad, and a very broad blackish 
hind-marginal border iii hind-iving ; basal area of fore-iving very broadly 
blackish ; ivhite ground thus reduced to a discal band in fore-ioing^ and 
a broad basi-central space in hind-ioing. Fore-wing: basal blackish 
extending from costa to inner margin, completely and exactly filling 
discoidal cell to its extremity, narrower and somewhat suffused below 
cell ; very broad apical hind-marginal border widest on costa (where it 
extends sometimes to a little before middle), somewhat abruptly nar- 
rowed near and at posterior angle, its inner edge regularly dentated on 
median nervules, — the dentation on third median nervule often more 
or less completely united to outermost extremity of black filling dis- 
coidal cell ; in blackish border, and towards its outer part, a subapical 
oblique row of three inter-nervular, elongate, rather ill-defined white 
spots (of which the lowest is rarely obsolete), between fourth subcostal 
and third median nervules. Hind-wi^ig : base narrowly and usually 
faintly irrorated with blackish ; hind-marginal broad border somewhat 
variable in width, its inner edge irregular and more or less suffused, 
but with a more or less marked dentation or prominence on second 
subcostal nervule. Under side. — Hind-wing and apex of fore-wing 
greyish-white with a very slight opalescent tinge and a faint marginal 
edging of yellowish; hind-marginal dark borders much duller than on 
upper side, especially in hind-iuing. Fore-wing : basal blackish much 
fainter, obsolete below discoidal cell ; yellow basal suffusion much more 
extensive than in ^, covering about two-thirds of cell, and reach- 
ing also to costal edge ; greyish-white apical patch representing on its 
inner side the white spots of the upper side. Hind-iving : yellow 
costal edging extending to middle or a little beyond ; hind-marginal 
border diffusedly narrowed in its lower half, and outwardly marked
