black line on the extreme terminal margin. In specimens from desert 

 regions the transverse fascise 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, black 

 series of spots of the ground-colour enclosed between them. Hindwing : 

 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 more or less obsolescent. 

 Forewing : discocellular spot as on the upperside but complete, and not an 

 oval ring ; in some specimens a postdiscal, dark ochraceous brown narrow, 

 curved band from costa to middle of interspace 2. Hindwing : a small dis- 

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

 than that on the forewing ; a postdiscal, curved, more or less sinuate band, 

 similar to and in continuation of the band on the forewing from costa to 

 vein 1. Antennte, head, thorax and abdomen dusky black, the club of the 

 antennte on the underside, 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 di-y localities. Sex-mark : a small patch of brown, specialized 

 scales on the underside of the forewing above vein 1, closer to the base 

 than to the termen ; on the upperside this is more or less prominent as a 

 raised spot. 



Female is dimorphic. For7Ji I : ground-colour and markings as in male ; 

 the costa of the hindwing on the upperside concolorous with the rest of the 

 wing ; the sex-mark of course absent. Form 2, upperside : ground-colour white, 

 often more or less irregularly suffused on parts of the wing with salmon- 

 buff" ; markings like in male though very much broader. Forewing : base 

 and costal area heavily irrorated with greyish-blue scales. Hindwing : the 

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

 a continuous band which then encloses an anteciliary series of spots of the 

 ground-colour. In a few specimens there are traces of a post discal, 

 macular, black band, in a very few this band is almost complete and very 

 prominent. Underside : ground-colour white, markings as in male but 

 broader, darker and more prominent. Expanse : 46-58mm. 



The race tripuncta, Butler, is described as follows : — 



Male and female : very closely resemble the typical forms ; but this, the 

 siiuthern form, can be distinguished as follows : — Male, upperside : ground- 

 colour a much deeper tint of salmon-buff", almost orange-yellow. Fore- 

 wing : the costa heavily irrorated with black scales ; discocellular spot 

 larger, not annular ; postdiscal, black fascia at all seasons united to the 

 subterminal fascia and black, anteciliary line so that the whole apex and 

 termen of the wing are black, broadly at the costa and gradually narrowed 

 towards the tornal angle. This black area encloses never more than three 

 preapical, moderately large spots and a complete series of minute, anteciliary 

 specks of the ground-colour. Hindwing : as in fausta, but the terminal 

 black spots very large. Underside: ground colour of a richer, yellower tint 

 than in the typical form ; markings similar, those on the forewing dusky 

 black, on the hindwing rose-pink. Antennte, head, thorax and abdomen 

 and sex mark as in the male of the typical form. Female, upperside : closely 

 resembles the female Form 2 of fausta, but all the markings are darker and 

 conspicuously broader, while the number of preapical spots of the ground- 

 colour enclosed within the black area on the forewing is never more than 

 three, the same as in the male. Underside: forewing: white, sometimes 

 faintly suffused with yellow ; apical and terminal areas anteriorly light to 

 dark ochraceous yellow ; discocellular spot very large ; transverse, post- 

 discal, macular, dark reddish-brown band very broad. Hindwing : pale
