less developed, following the outer and anterior margin of the cell, 

 and so having its concavity directed towards the root of the wing. 

 Some or all of the interspaces between the veins which traverse the 

 dark apex and hind border are marked by a powdering of white 

 scales, generally very indistinct, but in the space between the 

 fourth subcostal branch and the first radial vein assuming the appear- 

 ance of a definite white spot. The hind-wing may be entirely 

 immaculate, or may have the marginal ends of the veins marked 

 with black points. 



Underside. Fore-wing white; the costa slightly edged with 

 greyish yellow. Apical patch, correspondmg in extent with that 

 of the upper surface, of the same greyish yellow, bordered inwardly 

 with a slightly festooned streak of pale fawn-colour. A dark spot 

 more or less developed, in the second median interspace, corresponds 

 in position with the inward projection of the dark hind border 

 above. The spot on the second discocellular vein corresponds with 

 that on the upper surface, but is of a less intense black ; there may 

 or may not be a trace of the curved dusky band connecting it with 

 the costa. In some specimens there is a slight yellow shade at the 

 root of the wing. 



The hind-wing is of a greyish yellow like the apex of the fore-wing. 

 There is a streak of vivid orange along the whole length of the costa, 

 broadest near the body, and reachmg as far as the marginal end of 

 the first subcostal branch ; a short streak of the same colour occupies 

 the root of the interspace between the median and submedian veins. 

 The remaining marks are of the same pale fawn-colour as that 

 bordering the apical patch of the fore -wing. They consist of a slight 

 accentuation of the veins with their branches, broadening into a 

 patch on the second discocellular, and including the vestigial vein 

 between the median and submedian and that within the cell; in- 

 cluding also a patch between the origins of the first and second 

 median branches and another patch adjoining it internally; a 

 series of submarginal sjoots in the interspaces, those from the 

 second subcostal to the submedian vein taking an arrow-head form 

 with the pomts directed inwards; and, finally, a series of linear 

 spots at the marginal ends of the veins and theii" branches, parallel 

 with the margin, and occasionally fused into a narrow marginal 

 band. 



$. Exp. al. 53 mm. U2:)perside. Fore-wing white; hind-wing 

 varies from white through primrose yellow to deep yellow ochre. 

 Dark markings as in the male, but more pronounced. Fore-wing, 

 costal edging broader, apical black continued along hind margin as 

 far as anal angle; no separate marginal spots; no white dusting 

 in interspaces; the black spot on the second discocellular joined to
