THE BUTTERFLIES OF CEYLON 93 
in the drier districts, especially in the Southern Province 
from Tangalla to Hambantota, and at Anuradhapura, Jaffna, 
Mannar, etc. 
The males vary little, but the females grade perfectly from 
salmon colour to almost pure white, specimens as dark as the 
males being by far the rarest ; they also vary considerably in 
the ground colour of the under side. 
They fly slowly near the ground, and settle frequently, so 
are very easy to catch. 
160. CoLotis (IDMAIS) FAUSTA TRIPUNCTA, B. Idmats 
tripuncta, M.; Colotts (Madais) fausta fulvia, E. Also found 
in India. It differs from fausta in having three apical spots 
only. 
Moore figures the female the same colour as the male, but 
all the specimens I have seen have been white. The markings 
are the same in both sexes, so, if.a salmon-coloured female 
exists, she could only be distinguished by the different shape 
of the dorsal margin of the fore wing and the absence of the 
sex mark, which is a small oval patch of specialized scales on 
the under side of the fore wing above the basal half of vein I. 
It is found only in the north of the Island and is never 
plentiful. It has a very strong flight in the middle of the 
day in bright sunshine, but is easier to catch in the early 
morning. I have taken a few males at the blossom of Cadaba 
indica. It seems to frequent forest country more than any 
other member of the group, with the exception of amata. 
There is a fair amount of seasonal variation, but the dry 
season forms, especially of the female, seem to be very rare. 
I have specimens from Puttalam (October), Murunkan 
(July and November), and Elephant Pass (November to 
January), and I saw a fair number from the train near Madhu 
Road, on the Mannar line, in November. 
161. CoLoTis (CALLOSUNE) ETRIDA LIMBATA, B.; &. 
Callosune limbata, M. Peculiar to Ceylon, but is an 
insular race of the Indian C. etrida. It varies considerably, 
but the race seems to be well established everywhere, except 
in the Mannar District, where specimens that are very close 
to typical eivida may be taken in company with typical]
