138 SPOLIA ZEYLANICA. 
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 etrida may be taken in company 
with typical 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. I believe in this case that the insect had pupated 
on a Hambantota 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. 
“ Particularly abundant in Fort Frederick, Trincomalee ”

‘onfined 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 Giant’s 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 commence- 
ment 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
