Imago. —Male. Upperside. Forewing salmon-pink, paler than in Protractus, basal 
area with black and blue-grey scales, costal band imperfect, narrow and with black and 
blue-grey scales, the salmon-pink portion consequently much more extensive, a large 
black, usually round spot at the end of the cell with a black streak running inwards 
from it, outer band much as in Protr actus, but with a deeper curve on its upper margin 
below the apex and another below the middle. The spots larger, and of the ground 
colour of the wing, the lower one large and square. Hindwing as in Protractus, but 
the ground colour is pure white, with a few blue-grey scales at the base. Underside, 
both wings as in Protractus. 
Female. Upperside. Forewing paler than in the male, the costal band broader, 
more perfect and blackish-brown, the outer band much as in the male, but browner and 
with some pale pinkish spots on the exterior margin. Hindwing as in the male, but 
the exterior band is more brown, and paler, and there are some pale pinkish spots 
on the exterior margin. Underside. Both wings pale yellowish, tinged with pink, 
darkest on the costa of the forewing and the outer borders of both wings, the spots on 
the forewing larger, the cell spot usually white-centred ; a small spot white-centred at 
the end of the cell in the hindwing, and indications of a diseal whorl of conjoined brown 
spots. The general colour in this sex is sometimes yellowish above, with the base of 
the forewing suffused with salmon-pink, sometimes without this suffusion, and sometimes 
both wings are white. 
Expanse, £ $ 2 inches. 
Larva found feeding on Salvadora Persica at Aden; pea-green when young, two 
black spots on back of head, a white mark almost the shape of an ace of diamonds, but 
rather large on the second segment, when older the black spots on head disappear, and 
the white mark gets clearer and is outlined with black; there are tw r o similar marks 
just beyond the centre of the back, the front being the smaller, and another similar 
mark on the eleventh segment. (Nurse, Butler s Memoir, Proc. Zool. Soc. 1896, p. 245.) 
Pupa.— Pinkish-grey with the segments well marked, rests on its tail and is tied 
to the wood by a silk thread; well figured by Butler, Proc. Zool. Soc. 1896, plate 10, 
fig. 13.
