94 THE BUTTERFLIES OF CEYLON 
limbata. Their flight is so weak that it is difficult to imagine 
specimens of etrida crossing by Adam’s Bridge,.so they may 
only be extreme dry season forms of limbata ; they are almost 
invariably very dwarfed. (My specimens vary from 21 to 
32 mm. in expanse. ) In this connection I may mention that 
I have taken a specimen of limbata on the cart road at 
Haldummulla, at least 50 miles from its usual haunts, | 
believe in this case that the insect had pupated on a Hamban- 
tota salt cart, and hatched out on the road to Haputale, 
Specimens might, therefore, be easily brought over from 
India in a similar manner on the native boats, and thus 
interfere with the complete establishment of the race in the 
Mannar District. 
It is found all round the north and east coasts from Chilaw 
to Tangalla, but its range does not, as a rule, extend for as 
much as 10 miles inland. The largest and darkest specimens 
are found in the Hambantota-Tangalla District. It flies 
close to the ground, and is very easy to capture. 
162. CoLoTis (CALLOSUNE) EUCHARIS. Also found in 
India. 
Confined to the north of the Island and never found very 
far from the sea. It is very abundant in places in the Mannar 
and Jaffna Districts, especially near Giants Tank. 
Both sexes are very variable, and the variation seems to 
be largely dependent on season. In the dry season form of 
the male the black is confined to an external border to the 
orange patch on the fore wing, and very minute spots at the 
end of the veins on the hind wing. In the wet season form 
there is a large black patch on the fore wing below the orange, 
extending to the tornus, another small one on the costa at the 
commencement of the orange, and traces of an inner border 
connecting the two. The black spots on the hind wing are 
much larger, and sometimes coalesce to form a black border. 
In the females the orange spots at the apex vary in number 
from 3 to 5, 4 being the usual number; the orange often ex~ 
tends 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
