Description



A. perenna Dbl. and Hew. (54 e) is distinguished by the long, narrow forewing, with the termen emarginate, almost exactly the same shape as in Papilio antimachus; the discal dots are large and on the hindwing are placed near the base of their cellules (the one in 3 seems to be always absent); forewing above black with yellow-red hindmarginal spot, which covers the middle of cellules 1a to 2, beneath lighter, at the distal margin broadly yellowish with black veins and stripes on the interneural folds. Hindwing above black nearly to the discal dots, then with red transverse band and at the distal margin with black, red-spotted marginal band, beneath much lighter, at the base greenish yellow with free dots and some red spots or stripes close to the base; marginal band as above. Larva black with yellow spots; head and spines black. Sierra Leone to Angola, Uganda and Nairobi.

In thesprio Oberth. (54 e) the red-yellow colour of the forewing more or less completely covers also the cell and the base of cellules 3 to 6. Katanga; Nyassaland; German and British East Africa.
kaffana Rothsch. (59 f) nearly agrees with thesprio, but has the discal dots larger and the marginal band of the hindwing broader. Abyssinia.
