to “flighting,” especially during the north-east monsoon. 
During these flights it is common at Haldummulla, Kandy, 
and Galle, which are much further from its normal haunts 
than the distance across Adam’s Bridge, so it is easy to 
understand the introduction of fresh blood, from the parent 
species, in the north. 
It is very plentiful in the drier parts of the Island, especially 
in the Hambantota and Mannar Districts. The cream- 
coloured variety of the female is commonest in the wet 
season.

B.; Hyposcritia indra narendra, E.—Also found in Southern 
India. 
I have never come across this butterfly, my only specimen 
being a male from Ratnapura given to me by Mr. Mackwood, 
** Found also at 3,000 feet elevation in the country north of 
Matale and the Knuckles Mountains ” (F. M. Mackwood). 
168. CATOPHAGA VENUSTA, M.; Appias albina, B.; Cato- 
phaga albina venusta, E—Also found in India, Burma, 
Malaya, &c. 
Moore divides it into venusta and neombo. I have never 
seen anything at all resembling his figure of neombo 3, but 
those of the female and under side are clearly lightly marked 
varieties of venusta. It is, however, curious that he describes 
neombo as extremely plentiful, and venusta as having been 
taken only at Vavuniya. In both the white and yellow 
varieties of the female specimens may be captured in which 
the pre-apical black band on the under side of the fore wing 
is obsolete, except for a round spot in interspace 3. This 
variety, however, grades perfectly into the normal. 
The male can be distinguished from the next (C. paulina) 
by its more pointed wings. The female can be distinguished 
by having the outer margin of the black band on the under 
side of the fore wing, irregularly zig-zag, never regularly curved 
asin paulina 2. It has in addition, as a rule, four or five white 
spots at the apex of the fore wing above, while paulina has 
almost invariably only 3; but I have specimens of venusta 
in which these spots are reduced to two, those in interspaces 
3 and 4 being obsolete.
