Description
A. rogersi is characterized by the presence of black submarginal dots at least in cellules 1b and 2 of both wings. The fore wing has a basal dot in 1b, a black spot in the cell, one at its apex and large discal dots in 1b to 6, of which those in 1b to 3 are placed in a straight line running parallel with the distal margin. The upperside of the hindwing is usually so much darkened at the base as far as the apex of the cell that the basal dots are not distinct, and has a broad black marginal band; beneath there are basal dots in 1a to 1c, 7 and 8 and two in the cell; the discal dots are usually present in all the cellules, but are irregularly arranged, the spots in 1c and 4 being placed nearer to the base than those next to them, a black dot on the middle discocellular; the submarginal dots are placed just before the marginal band and occur in the female in cellules 1b to 7, in the male often only in 1b to 3. Larva black-brown with black spines and black head. Pupa light yellowish brown with fine black striae; head with two long, obtuse, divergent horns. Lagos.
 * rogersi Hew. Black above with a transverse band 8 to 9 mm. in breadth on the hind wing and a large spot at the hinder angle of the fore wing in cellules 1 a to 2 in the male red or red-yellow, in the female only indistinctly reddish. Sierra Leone to Angola.
 * salambo Sm. (56 d). Both wings smoky brown above, more or less broadly relieved with yellowish grey in the middle. Among the type-form,
 * lamborni Eltr. is similar to the preceding form, but has a dirty cream coloured transverse band on the upperside of the hindwing.
