Description

For a key to the terms used, see Glossary of entomology terms.

A. oreas E. Sharpe (57 c). Both wings deep black above, with yellow markings; the forewing spotted quite as in [forma] fallax and confusa , but in addition with a similar spot in the cell; the hindwing with a long but narrow median area, which covers the cell and the base of cellules 2-7, but is proximally bounded by vein 2, thus not nearly reaching the inner margin; the fore wing is somewhat longer and narrower than in johnstoni and lycoa. On the under surface the hindwing and the apical part of the forewing have a rust-brown ground colour with black longitudinal streaks; the light markings almost as above, but the yellow median area of the hindwing emits a branch to or almost to the middle of the inner margin. Angola; German and British East Africa; Uganda, ab. albimaculata Neave. Spots of the forewing white. In the same localities as the type-form. f. angolana Lathy.[ now subspecies ] Marginal band of the hindwing beneath and apical part of the forewing with grey-yellow ground-colour; spots of the forewing white. Angola. female-ab. radians ab. nov. (= angolana female-ab. Lathy) only differs from angolana in the yellow median area of the hindwing above extending in broad rays between the veins nearly to the distal margin; the spots on the upperside of the forewing yellowish. Angola. ^[4]
