THE BUTTERFLIES OF CEYLON 7 
4to 7. In asela from 3 to 6. 
Mr. A. C. Hayley has called my attention to another means 
of distinguishing them, which, to judge from the specimens 
in my collection, seems reliable. 
In interspace 1 on the under side of the fore wing— 
2 asela has one long milky white streak (about 10 mm. 
long). | 
2 montana has two similar streaks. 
° sinhala has a very minute white streak, or narrow spot, 
seldom over 2 mm. in length. 
The males can be easily distinguished by the sex mark, 
which is a black shiny mark in interspace 1 of the upper side 
of the fore wing, as follows :— 
One short narrow streak = asela. 
Two long rather broad streaks = montana, 
One short oval spot = sinhala.

Found also in S. India. 
It is so constant and geographically separated a form that 
it seems to deserve specific rank, though the more recent writers 
treat it as a race of O. meda of N. India, Burmah, Malaya, 
etc., from which it differs “‘on the under side in having 
the transverse band three times the width that it is in that 
species’ (Moore). -It varies very little in Ceylon, but I have 
seen two specimens in which the white band was almost 
obsolete: One was taken by Mr. T. G. Elliott at Kumbukkan, 
near Moneragalla, and the other by Mr. John Pole at Nawala- 
pitiya. The latter is figured in ‘‘Spolia Zeylanica,”’ Vol. IX., 
Part XXXIII. They are however quite distinct from meda. 
It is very common all over the southern portion of the 
Island, from sea level to over 4,000 feet at least, all the 
year :ound, but I have not yet noted it in the Northern or 
North-Central Provinces. It is found in paddy-fields 
and in grass by the roadsides, or near jungle, but does not
