CEYLON BUTTERFLIES. 1733 
The only place I have seen it is on the cart road near 
Haldummulla in March and May. 
In working out this group, I am greatly indebted to some 
notes on Indian Butterflies published by Colonel Evans in the 
Journal of the Bombay Natural History Society (Vol. X XIIT., 
p. 307). Lam also indebted to Mr. F. Hannyngton, I.C.S., for 
some specimens of two forms from Coorg. One of these is 
very like pseudomesa externally, but the prehensores are quite 
distinct ; the other is very unlike any Ceylon form both 
externally and internally. 
219. HALPE CEYLONICA.

Halpe egena is restricted to Ceylon. H. ceylonica is also 
found in Southern India. 
According to Moore, who described brunnea (= egena) from 
a single female specimen, the chief distinction between it and 
ceylonica lies in the ground colour, which is “ dark vinous 
brown ”’ in brunnea, and “ dark brown, base of wings and body 
olive-brown,”’ in ceylonica. 
Elwes and Edwards distinguish them by the discal band 
on the under side of the hind wing, which is brownish-yellow, 
and very indistinct, in egena, and yellowish-white, and clearly 
defined, in ceylonica. The colour of the discal band is usually 
as they state, but it varies greatly in definition, and I have 
specimens of ceylonica in which it is so diffuse as to be almost 
indistinguishable. My experience is that the ground colour 
is the only reliable test. In the specimen of egena described 
by Moore the discal band was evidently exceptionally indis- 
tinct. As a rule, the spots on the fore wing are larger in 
ceylonica, but they vary much in size in both. In ceylonica 3 
the pre-apical spots vary from 1 to 3 in number, but the discal 
spots vary only in size. I have a specimen of egena 3 with 
the wing entirely unspotted. The spot in the cell is rarely 
present in egena 3, and rarely absent in ceylonica 3. I can 
perceive no difference whatever in the prehensores. See PI. 5, 
figs. 9 and 10. The females are much rarer than the males, 
and the material at my disposal is rather limited. Apart 
from the ground colour, the chief difference between them 
seems to be the spots in interspace | of the fore wing. I have
