fore wing, black, the black edging to the discocellulars and apical 

 portion of the median vein of the fore 

 wing broader; the apices of veins 3 to 7 

 increasingly broadly black-marked. Hind 

 wing uniform. Both fore and hind wings 

 with a slender marginal black line along 

 costa, termen and dorsum ; this is more 

 or less interrupted in the middle of the 

 dorsum of the fore wing; base with a 

 slight irroration of black scales. Under- 

 side : ground-colour white ; fore wing on 

 costa narrowly and on apex, hind wing all 

 over, suffused with pale yellow ; markings 

 similar. Hind wing : the precostal area 

 Fig. 41. Aporia soracte. chrome-yellow, the discocellulars some- 

 what prominently defined with black ; 



interspace 2 divided longitudinally by a black line. Cilia of wings 

 dusky brown. Antennae black ; head, thorax and abdomen white, 

 generally strongly suffused with fuscous black ; beneath : head, 

 thorax and abdomen white.

 The markings on both upper and under sides are to some extent 

 variable, but I have not seen a sufficient number of dated spe- 

 cimens to make out whether the variation is seasonal or not. 

 Thus many, both males and females, have on the upper and 

 under sides of the fore wing a postdiscal, curved, diffuse, trans- 

 verse black band between veins 2 and 3 continued anteriorly from 

 veins 4 to 10 ; a few specimens have also on the hind wing, both 

 on the upper and under sides, some diffuse black scaling on the 

 disc that takes the form of outwardly acute sagittate marks in 

 the interspaces.

c? 5 . Eesembles A. soracte, but is smaller, and may be distin- 

 guished as follows : Upperside fore wing : the discocellular black 

 spot broader, the dilatation of the black at the apices of the veins 

 also much more marked ; in addition there is always a black 

 postdiscal band that runs obliquely from costa at apex of vein 10 

 to vein 5, thence transversely to vein 2, subinterrupted iu inter- 

 space 3 and broadened in interspaces 2 and 4. Underside : differs 

 from that, of soracte in the apex of the fore and the whole of the 

 hind wing, which are suffused with a darker yellow, the black 

 edging to the veins is broader on both fore and hind wings, and a 

 postdiscal black band is always present on both wings ; on the
