which mimics the typical female egina (fig. 3), the fore-wings 
are grey-brown with neither white nor yellow subapical 
area, and only a faint trace of pinkish brown suffusion 
at the anal angle. The hind-wings are red brown, re- 
sembling those of the egina female. The second Western 
9, taken by Neave in the S8.E. of the Congo State, about 
150-200 miles W. of Kambove, in 1907, has the typical 
appearance of an Hastern female. This is in accordance 
with the affinities displayed by other species from the 
same area. 
The conclusion is that the female, as well as the male, 
Pseudacraea boisduvali, of Bugalla Island, L. Victoria, 
follows the typical Western form in mimicking Acraea 
egina instead of Acraea zetes; the evidence being peculiarly 
convincing because the 2 egina, but not the @ zetes, appears 
as a striking local form which is mimicked by the 2 Pseud- 
acraea. In the male the resemblance to the model is not 
quite so perfectly developed as in the Western form, it 
being intermediate between that and the Eastern form, 
although much nearer to the former, as in certain other 
Uganda species which range from East to West. 
Addendum. 
Since writing the above I have had, through the kind- 
ness of Mr. Roland Trimen, F.R.S., an opportunity of 
examining the Ps. boisduvalc in his private collection, 
containing a fine series of specimens bred in 1910 by the 
late A. D. Millar, at Durban. 
In this series there are 12 males and 13 females. 
Of the 12 males, 6 were of the typical, highly-coloured 
Eastern form with very conspicuous large orange-yellow 
subapical area on the fore-wing. In 4 males the orange 
area was smaller, and from two only was it absent. One of 
the specimens with much orange had well-defined black 
suffusion over the base of the fore-wing, but none of the 
others exhibited any signs of this. 
Of the 13 bred females, 10 were of the typical Eastern 
form, with well-marked orange areas on the fore-wing; 
the other 3 had the yellow much reduced, or whitish in 
colour. 
Mr. Trimen also has 2 females, caught, one in Zululand 
and one at Malvern in Natal. These are typically Kastern, 
and one has a very slight suffusion with white on the hind- 
wing about the centre.
