PIERTNiE. 41 



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 suliused 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 nerv^ule. Hind-iving : 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. — Hind-ioing and apiccd lorder of fore-wing faintly tinged 

 with rather dull 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-iving : 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. 



$ Blackish border of fore-wing very Iroad, and a very hroad hlacJcish 

 hind-marginal lorder in hind-wing ; basal area of fore-wing very broadly 

 blackish ; luhite ground thus reduced to a discal band in fore-wing^ and 

 a broad basi-central sjmce in hind-iving. Fore-iving : basal blackish 

 extending from costa to inner margin, completely and exactly fillino- 

 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 ner\Tiles, — the dentation on third median nervule often more 

 or less completely united to outermost extremity of black fillino- 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-u-ing : base narrowly and usually 

 faintly irrorated with blackish ; hind-marginal broad border somewhat 

 variable in width, its inner edge irregular and more or less sufiused, 

 but with a more or less marked dentation or prominence on second 

 subcostal nervule. Under side. — Hind-wing and apex of fore-icing 

 greyish-white with a very slight opalescent tinge and a faint marginal 

 edging of yellowish; hind-marginal dark borders much didler than on 

 upper side, especicdly in hind-wing. 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
