10. Sub-species Indiensis. 
Some specimens sent me by Captain Cornwall, from Madras, 
present certain differences in venation to A. annularis , but 
which are only of sufficient importance to found a sub-species on, 
as all the other characters are similar to the typical A. annularis 
from the Malay Peninsula. In this sub-species the two fork- 
cells are relatively much longer than in the type (Fig. 34), the 
base of the first sub-marginal cell being quite close to the first 
costal spot, that is close to the junction of the sub-costal with 
the costal; the fringe scales are also pale at the end of the lower 
branch of the fifth long vein, whilst the cross-veins resemble most 
nearly those of A. annularis (type). 
The peculiarity in the venation of this variety places it very 
near the specimens sent by Professor Grassi and called by him 
A. pseudopictus, but it differs in regard to the relative positions 
of the cross-veins.
