This fine species is generally somewhat larger 
than the preceding, the male of a fine sulphur-yel- 
low (sometimes, however, nearly white) ; the female 
white, faintly tinged with sulphur. The upper wings 
are greyish at the base, marked with a black spot 
near the middle anteriorly, and having at the extre- 
mity a broad black border, which is attenuated at the 
binder angle, and almost divided by a series of nearly 
continuous spots down the middle. The under 
wings have a large orange spot on the disk, with a 
small one attached to it; the margin next the upper 
wings is dusky, and there are a few dusky spots re- 
mote from the outer edge, and nearly parallel with 
it. Beneath, the upper wings are whitish -yellow, 
suffused with orange at the tip, having a discoidal 
black spot with a yellow centre, and a row of small 
dusky marks at some distance from the outer mar-
