Upper Egypt, the White Nile, and Abyssinia, and chiefly 
differs in its inferior size, yellower colouring, and frequently 
in the larger orange patch on the primaries. T’. syrtinus is 
an intermediate-season form which apparently ranges west- 
wards from Mombasa through the Sabaki valley, past Kilima- 
njaro and the Victoria Nyanza to Wadelai, and thence across 
the continent to Senegal, where it varies slightly from the 
normal form, the lower extremity of the orange apical patch 
being indistinetly bordered with blackish, so as vaguely to 
resemble the wet-season form of 7’. auxo (nobody, however, 
with an eye for species could calmly compare the two and 
fora moment regard them as identical). The males of this 
form never have the margin of the secondaries dotted, and on 
the under surface they show a slight tendency to rosy tinting. 
The females are altogether more lightly marked than those of 
typical 7. evarne. TT. liagore is probably little more than a rare 
starved albinism occurring in Egypt and on the borders of 
the Red Sea; in its weak markings it would seein to be 
a dry-season form, but the colouring of the under surface 
is that of the wet-season. I should look upon it as an inter- 
mediate form probably occurring just before the rains. 
T. citreus is the dry-season form occurring with typical 
T. evarne, but smaller, much more lightly marked above, and 
very rosy below.

This is a well-defined local representative of 7. evarne most 
nearly approaching the varietal form 7. /éagore in character. 
In all its seasonal phases it is much more lightly marked and 
-paler in colouring than 7’ evarne, as well as slightly smaller 
than in the corresponding phases of 7. evarne. ‘The ground- 
colouring is always white, with the pale orange apical patch 
very faintly tinted with yellow along the inner edge; the 
marginal bordering even of the wet-season male is compara- 
tively weak, while the secondaries are always unspotted. 
The female in the wet-season has the upper surface marked 
almost as in the dry-season female of 7’. evarne, while the 
intermediate type, which is much smaller, has the female 
still less marked above and striated below with greyish olive ; 
the dry-season form is very small, the male withont marginal 
markings, the female very faintly marked, but both sexes 
rosy and more or less striated below.
