and having seen the specimen I agree entirely with this 

 view. It is remarkable that these small black and yellow 

 Acraeas occasionally produce forms in which the yellow 

 is replaced by red, whilst the red and black species 

 produce yellow and black varieties. Thus there is a $ 

 form of A. i^enclope with yellow h.-w., and a ^ form of 

 servona with the typical yellow replaced by red. The 

 case of orestia is still more peculiar since we have the 

 red, an orange intermediate, a yellow, and a colourless 

 form. 



The present species has a wide distribution, extending 

 from the neighbourhood of the Kassai R. to Entebbe.

(J. Exjianse about 44 mm. F.-w. brownisli black. At end 

 of cell a large lemon oclireous spot occupying the outer third 

 of cell, its proximal edge indented by the groiuid-colour, and 

 beneath it at base of area 2 a somewhat similar lemon oclireous 

 spot. Beyond cell, midway between cell end and apex a 

 slightly curved row of three subquadrate spots. These spots 

 are tran.slucent and appear to be white, but if examined by 

 reflected light only they are seen to be lightly scaled with 

 lemon ochreoiis. 



H.-w. brownish black with a lemon ochreous central patch, 

 occupying basal part of 6, 5, 4, 3 (very slightly) and 2, ex- 

 tending thence in a narrow continuation nearly to inner 

 margin, and also occupying the lower outer half of cell. On 

 the dark basal portion the spots of underside are just visible, 

 and in addition there is a black mark at extreme base of areas 

 5 and 4 on the discocellulars and plainly visible on the pale 

 yellow ground. On the outer dark coloured half of the wing 

 the dark internervular rays are visible. 



Underside. F.-w. costa pale greyi.sh ochreous, remainder of 

 wing blackish with pale spots as above but the large yellow 

 spots are only very slightly scaled and inclined to be larger 

 than above. At apex between the Ijranches of subcostal, and 

 along apical and hind-marginal border, between the black 

 nervules and rays, pale lemon ochreous. 



H.-w. lemon ochreous, slightly dusky over those areas which 

 are black on uppei'side. The marginal border is striated by
