(in 1 a to 2) is narrowest in 1 a, distally strongly incised at the veins; in 2 and 2 $$ it is dull ochre- 
yellow, in one $ densely dusted with yellow-red, in another with black, in 3 examples yellow-red; the longitu¬ 
dinal streak at the hindmargin of the cell is indistinct in the specimens with predominantly yellow markings, 
distinct in those with the red ones and in one $ even encroaches into 1 a, so that this specimen somewhat 
approaches Acraea bonasia. On the hindwing the very narrow median band recedes far from the distal margin 
in cellule 3, where only a very small light spot still persists, but projects distad in 4 and 5 in the shape 
of a double tooth; the median band is in 2 pairs dull ochre-yellow, in 1 and 1 $ in cellule 2 distally, 
in 4 to 6 for its entire breadth dusted with yellow-red, in the other specimens yellow-red. Light marginal 
spots are only indicated in one $ by sparse yellow scaling. On the under surface rupicola likewise nearly 
approaches karschi. Expanse 37 to 42 (rf) to 44 to 46 ($) mm”. Primeval forests of the South Cameroons, 
where the species seems chiefly to frequent the cool granite rocks which occur here and there; was taken 
flying round a yellow-flowered Composite. — I was not able to introduce this species in the synopsis. 
A. cabira may be known by the hindmarginal spot on the uppersicle of the forewing completely covering 
the base of cellule 2 and reaching the cell in 1 b also; the light spot in 1 b is, however, proximally cut 
off obliquely and hence much narrower at vein 1 than at vein 2, so that the hindmarginal spot assumes 
a peculiar shape. The median band of the hind wing is widened in cellules 4 and 5 and on the under sur¬ 
face the hindwing has always broad red streaks in the cell and in cellule 8 and at the distal margin the 
whitish marginal spots are proximally prolonged into red, black-edged streaks and the veins bordered by grey 
lines. Forewing beneath reddish to yellow-brown in the cell and at the base of cellule 1 b. ■— In the type- 
form cabira Hpff. the markings of the upper surface are light yellow and the hindmarginal spot of the forewing cabira.

A. uvui 8m. (56 b) is a small species and may be known by having the markings of the upper sur- uvui. 
face yellow-red (only at the inner margin of the hindwing light yellow) and the proximal edge of the 
hindmarginal spot of the fore wing straight and sharply defined; it covers the base of cellule 2 and also forms a small 
spot in 3 and in the apex of the cell. In the type-form the hindwing has on the underside no red streaks 
between the basal clots and no light stripes in the black marginal band; the subapical band of the fore wing 
is nearly straight. German and British East Africa; Uganda. —- balirsa Karsch (56 b). Spots 4 and 5 of the balina.

spots. Hindwing beneath with light yellow ground-colour, at the base with black dots but without red spots 
or streaks; its marginal band deep black without light stripes and with no spots except the white mar¬ 
ginal ones. Cameroons; Ruwenzori; Uganda; British East Africa; Kilimandjaro. — $-ab. tenelloides Poult, tenclloides.

A. bonasia is nearly allied both to alicia and to sotikensis and all three probably belong to one species. 
From alicia, which Eltringham regards only as a form of bonasia, it differs in having the base of cellule 2 
of the forewing black and from sotikensis it seems to me only to differ in having the light longitudinal stripe at 
the median of the forewing above completely united with the hindmarginal spot. On this ground I also refer 
praeponina Stgr. to sotikensis. •—- bonasia F. (56 b). Markings of the upper surface yellow-red; the black dots bonasia.
