Description

''A. pharsalus'' Ward. (56 d). Upper surface of both wings dusted with black at the base; forewing above very broadly black at the apex and distal margin with small whitish (occasionally reddish) subapical spots in 4 to 6 and large discal dots in 1b to 6, of which those in cellules 4 to 6 are scarcely distinguishable from the ground-colour; cell with a black spot in the middle and one at the apex; the middle of the forewing and the greater part of the hindwing above red, the hindwing with black marginal band; forewing beneath reddish grey, at the apex and distal margin yellowish with black veins and marginal streaks; hindwing beneath at the base and distal margin greenish light grey, in the middle slightly reddish with well developed basal and discal dots and large triangular spots at the distal margin on the interneural folds. Larva above red-yellow, beneath lighter, with black dorsal line and small black striae at the anterior and posterior margin of each segment; head and spines black. Pupa light yellowish with black markings. Senegal to Angola, Nyassaland and Uganda.
* ''pharsaloides'' Holl. (= ''saluspha'' Suff.) is the East African race and only differs in having the light subapical band of the forewing much larger and red, connected with the red ground-colour by a spot of the same colour in 3; hence the black discal dots in cellules 3 to 6 appear as independent spots; the base of both wings above is less dusted with black than in the type-form. In the female the ground-colour of the upper surface is often grey-yellowish. Angola, German and British East Africa.
* ab. ''pallidepicta'' Strand Subapical band of the forewing whitish. German East Africa.
* ab. ''nia'' Strand, forms in certain respects the transition to ''vuilloti'', as the hindwing has a light yellowish patch in the same position as in the latter. German East Africa: Amani.
* ''vuilloti'' Mab. ow species ''Acraea vuilloti'' ">Acraea_vuilloti.html" ;"title="ow species ''Acraea vuilloti">ow species ''Acraea vuilloti'' 56 d). The ground-colour of the forewing is often completely broken up into spots and the hindwing has a large white spot at the inner margin in cellules 1b to 2 (to 3). Hindwing also beneath with dark marginal band. Marginal streaks thick, but not triangular. German East Africa.
* ''rhodina'' Rothsch. Forewing as in ''vuilloti'' ; hindwing also similarly marked, but without white area. Abyssinia.
