THE BUTTERFLIES OF CEYLON 95 
caught were worn specimens. I have, however, failed to 
produce the effect by exposing dead specimens to sunlight for 
some weeks. The under side of both sexes varies greatly in 
ground colour and markings. 
In bright sunshine its flight is rather fast, though faa and 
owing to the thorns it is not easy tocatch. In cloudy weather 
it flies little, and, if beaten up, is easily taken. 
163. CoLoTis (CALLOSUNE) DANE, B. Moore also gives 
sanguinalis, which is only the small dry season form. Also 
found in India and Persia. 
I have never seen it out of the Néthern Province, though 
I believe it has been taken at Puttalam. It is extremely 
plentiful in the Mannar District, and is not rare at Kankesan- 
turai on the Jaffna coast. The females are usually much 
scarcer than the males, but I found them in profusion at 
Murunkan in July. 
It flies with C. escharis, and has the same habits, its flight 
in bright sunshine being rather fast, but it is easy to catch 
in the early morning or in cloudy weather. Both species con- 
gregate round bushes ot Cadaba indica, which is apparently 
the chief food plant of their larve in Ceylon, and they may 
be found roosting at the foot of these bushes in the evening, 
and the finest specimens can be easily selected. 
It seems to vary much less in Ceylon than either eucharis 
or limbata, the chief variation being in the ground colour of 
the underside. Dry season specimens are very often dwarfed. 
164. ANAPH&IS MESENTINA TAPROBANA, B., E. Belenois 
taprobana, M. Peculiar to Ceylon, but is an insular race 
of A. meseniina, which is found from Africa to India. 
It is very variable, but seems to be well established as a 
race, except in the north of the Island. I have single speci- 
mens from Jaffna and Mannar, and have seen one from 
Anuradhapura, which are very near typical mesentina, 
though the under side of the hind wing is chrome-yellow in 
all. It is much given to “‘ flighting,’’ especially during the 
north-east monsoon. During these flights it is common at 
Haldummulla, Colombo, Kandy, and Galle, which are much 
further from its normal haunts than the distance across Adam ’s.
