CEYLON BUTTERFLIES. 139 
to 5, 4 being the usual number; the orange often extends 
into the wing within the inner border of the black area. In 
some specimens the apical spots are nearly white. This may 
be the result of fading, as the majority of those I have 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 low, and 
owing to the thorns it is not easy to catch. In cloudy weather 
it flies little, and, if beaten up, is easily taken. 
165. CALLOSUNE DAN/E, M. & E.; Colotis dane, B.; ' 
Teracolus dane, De N.—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 Northern 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. eucharis, 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 of 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 than either eucharis or limbata, 
the chief variation being in the ground colour of the under 
side. Dry season specimens are very often dwarfed. 
166. BELENOIS TAPROBANA, M.; Anapheis mesentina 
taprobana, B. & E.—Peculiar to Ceylon, but is an insular race 
of B. mesentina, 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. [have single specimens 
from Jaffna and Mannar, and have seen one from Anuradha- 
pura, which are very near typical mesentina, though the under 
side of the hind wing is chrome-yellow in all. It is much given
