though many of these females have such a broad brownish 
border to the white band on the hind-wing that they are 
to some extent intermediate between the typical eastern 
Uganda @ form aurivilliz, and the typical western female. 
Of the 17 alciope which were taken 5 were males, 11 were 
of the eastern form of female (awrivillii), and one transi- 
tional towards the typical western form, which closely 
resembles the male Pl. alcinoe mentioned below. The 
single transitional 9 resembled this model so closely that 
I was quite deceived by it even after I had seen the speci- 
mens in the cabinet. The male Acraea alciope stands by 
itself, and does not mimic anything in either KE. or W. 
Africa. The scarcity of this species on Bugalla Island is 
remarkable—and probably due to scarcity of its food-plant, 
which I never saw there. On another island, where I was 
previously (Damba), the food-plant was abundant, and 
alciope was extremely common. 
The Pseudacraea mimic is the male of the mimetic form 
hobleyr, of Ps. eurytus hobleyi (Plate XXXV, fig. 12; 
XXXVI, fig. 9). This mimic is abundant on Bugalla, 28 
having been captured. The resemblance is so close that 
I was often deceived until I had learnt to distinguish them. 
Another Nymphaline member of this combination is 
Precis rauana, whose male is non-mimetic, but the female 
mimics well the male macarista : 24 males and 23 females 
were taken. This species is not often seen actually within 
the forest, but is to be found along the border-line between 
the forest and the open grass-land, or at the edge of the 
forest on the shore. In both these localities may be found 
beds of a thick-leaved aromatic Labiate herb, which may 
be the food-plant of the larva of this species. It is to be 
found also on the flowers of the “ Gamboge ” tree, Haronga 
madagascariensis, Chois. (Hypericineae), which particularly 
favours such localities, and attracts numbers of all the 
butterflies mentioned in this paper. 
Precis rauana has the typical, very dashing and rapid 
flight of the genus to which it belongs, and is unlike that 
of its model. But the general impression gained from its 
appearance leaves no room for doubt that the female zs a 
mimic of the male Pl. macarista. The male, having no 
white on the hind-wings, is not mimetic of this Planema, 
but on the other hand a fresh specimen often has such 
a rich crimson suffusion over the light-coloured band on 
the wings that I think it presents a decidedly Acraeine
