C? . Upperside : chalky-white, sometimes with a more or less 

 broad and clearly defined basal sulphur-yellow area on both fore 

 and hind wings ; this sulphur-yellow colour is at times diffused 

 over the whole surface of the wings, though generally it becomes 

 paler towards the terminal margins. Fore wing : the whole, or 

 sometimes only the apical half, of the costa narrowly black, 

 this colour widened out irregularly at the apex ; termen widely 

 black at the apex, the colour narrowed posteriorly. This border 

 in some specimens almost reaches the tornus, in others ter- 

 minates above vein 4 ; occasionally ifc is continued posteriorly 

 by a series of black dots at the apices of the veins. Hind 

 wing : generally uniform, unmarked, some specimens bear minute 

 black dots at the apices of the veins. Underside : ground- 

 colour very variable, white with a slight to strong ochraceous 

 tinge, greenish white or sulphur-yellow. Fore wing : typically 

 without markings, in some specimens with a patch of sulphur- 

 yellow on either side of base of median nervure ; in the very 

 yellow examples the tornal area is often widely greenish white; 

 in others (C. catilla, Cramer) it bears a spot variable in size on 

 the discocellulars, this spot has a pearly centre and an outer
