96 THE BUTTERFLIES OF CEYLON 
Bridge, so it is easy tc 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, in the South-East of the Island. 
165. APPIAS (HyPOSCRITIA) INDRA NARENDRA, B.,,. E. 
- Hiposcritia narendra, M. Also found in S. India. 
I have never come across this butterfly, my only specimen 
being a male from Ratnapura given to me by Mr. Mackwood. 
It is also found in the Knuckles District and North Matale. 
The material is so limited that it is impossible to say whether 
our Ceylon form is entitled to rank as a race, or species. 
166. Appras (CATOPHAGA) VENUSTA, M. Aphias albina, 
B.; Catophaga albina venusta, E. Also found in India, 
Burma, Malaya, etc. 
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is obsolete, except for a round spot in interspace 3.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 (A. patulina) 
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 as in paulina 9. 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. 
It is very plentiful everywhere during the flights, but is 
not often found at high elevations, except when these are on,
