c? . Upperside : pale salmon-buff, paler in specimens from 

 desert areas, darker in those procured in regions where there is a 

 regular though not heavy rainfall. Fore wing : base and costal 

 margin irrorated in varying degree with dusky scales ; an oval 

 annular discocellular spot that varies in size ; a black, festooned, 

 postdiscal fascia that extends from costa to vein 4, beyond which 

 the veins are margined with black ; this colour broadened sub- 

 terminally into a second transverse fascia, that is followed by a 

 very fine black line on the extreme terminal margin. In specimens 

 from desert regions the transverse fasciae and the black edging to 

 the veins are narrow, but in moister areas the two transverse 

 fasciae unite posteriorly and with the slender black terminal line 

 give an appearance as of a double series of spots of the ground- 

 colour enclosed between them. Hind wing : more uniform, the 

 veins with terminal black spots ; costa broadly pale, fading to 

 white. Underside : pale yellowish white, in many specimens from 

 moist localities suffused with a beautiful rosy flush ; the markings 

 in such specimens prominent, in those from dry localities inore or 

 less obsolescent. Fore wing: discocellular spot as on the upper- 

 side, but complete, and not an oval ring ; in some specimens a 

 postdiscal, dark ochraceous brown, narrow, curved baud from 

 costa to middle of interspace 2. Hind wing : a small discocellular 

 spot in the form of an oval light brown ring always much smaller 

 than the similar spot on the fore wing ; a postdiscal, curved, more 

 or less sinuate band similar to and in continuation of the band on 

 the fore wing from the costa to vein 1. Antennae, head, thorax 

 and abdomen dusky black, the club of the antennae on the under- 

 side, the hairs that cover the head and thorax and the scaling of 

 the abdomen salmon-buff ; beneath : much paler, fading to white in 

 specimens from dry localities. Sex-mark : a small patch of brown 

 specialized scales on the underside of the fore wing above vein 1, 

 closer to the base than to the termen. On the upperside this is 

 more or less prominent as a small raised spot. 



$ . Dimorphic. Form 1 : ground-colour and markings as in the 

 c? ; the costa of the hind wing on the upperside concolorous with the 

 rest of the wing ; the sex-mark of course absent. Form 2. Upper- 

 side : ground-colour white, often more or less irregularly suffused on 

 parts of the wing with salmon-buff ; markings similar to those in 

 the d , but very much broader. Fore wing : base and costal area 

 heavily irrorated with greyish-blue scales. Hind wing : the 

 terminal spots at apices of the veins large and quadrate, often 

 united into a continuous band which then encloses an anticiliary
