the Prince’s Island form. On the lower surface, the wings 
show a little more yellowish tint than in the true medea, 
in this also being intermediate between the type and this 
subspecies. 
Unfortunately I only caught four specimens, not realising 
at the time the interest attaching to them, so that I cannot 
show from my own experience that they are the only form 
of female egina on Bugalla Island. That they are the only 
form is also indicated by Griinberg (Trans. Ent. Soc. Lond., 
1913, p. 412), and I hope to put the matter beyond doubt 
on my return to Bugalla; for egina is an abundant species 
there. I was struck with the general likeness of this pale 
form to Planema consanguinea albicolor, Karsch (arenaria, 
EK. M. Sharpe), when seen at a little distance on a flower 
head. 
Now the Bugalla females of Pseudacraea boisduvali are 
also peculiar in the large development of a white suffusion 
on the fore-wings. This varies much in degree in the 
twelve specimens, but in that which shows it best (Plate 
XXXVIII, fig. 10) there is a white subapical area, and much 
of the basal half of the fore-wing is whitish, a pinkish tint 
being confined to the base. The hind-wings are of a dull 
brownish, like those of a typical 2 egina, but there is a 
whiter patch on the anterior margin. The likeness of 
this specimen to its model (Plate XX XVIII, figs. 3 and 4) 
is further accentuated by the row of heavy black spots 
just internal to the subapical white patch on the fore-wing. 
These spots are only just indicated in the other specimens 
(figs. 8, 9), but they form a characteristic marking of the 
model. 
In none of the 12 Bugalla females is there the large 
yellow subapical patch which is a conspicuous feature of the 
Kastern Q boisduvali, which resembles Acraea zetes acara, 
though in 9 of them the white patch which takes its place 
has a trace of yellow suffusion at the hind-marginal end. 
In these points they agree with Neave’s 3 specimens 
from the mainland of Uganda. None of Neave’s, how- 
ever, show the white suffusion over the base of the fore- 
wing, so characteristic of the Bugalla specimens, and not 
shown in any of the 39 Southern and Eastern forms. 
The Western female of boisduvali is represented in the 
Hope Department by two specimens, one of which comes 
from Sierra Leone, and was purchased in 1901 from 
Watkins and Doncaster. In this (Plate XX XVII, fig. 4),
