8 SPOLIA ZEYLANICA. 
A common insect in the drier low-country. It often joins 
in the flights, and in December, 1902, it was for a few days by 
tar the commonest Euplcea in the flight. 
It is very common at Wellawaya, in the low-country of Uva, 
and at Anuradhapura, Ihave also taken it at Galle and Jaffna. 
It is not found at high elevations, except during the flights, 
12. SricLopLa@a MONTANA, De N.; Narmada montana, M.; 
Sticto plea coreta montana, B. & E.—Peculiar to Ceylon, but is 
only a race of the Indian S. coreta, from which it differs in the 
same way as asela from core and sinhala from kollart. 
| It is almost as abundant as asela in the flights, but does not 
usually appear till they have been on for some days. 
Like sinhala, it does not seem to remain at high elevations 
after the flights end, but it is then common in many parts of 
the low-country, particularly in the dry zone. 
The females of the three species asela, sinhala, and montana 
are difficult to distinguish. 'The usual rule is 

A.—Under side fore wing : no spot in cell = sinhala. 
B.—Under side fore wing : white spot in cell : 
A 1,—No spots outside cell above veins 5 and 6 = asela. 
Lb 1.—Complete series of spots between nerves immediately 
outside cell = montana. 
T have specimens of both asela and montana without the spot 
in the cell.. This variety is quite common. Ihave also— 
Montana : Only 4 spots outside cell ; no spot above vein 5, 
Asela ; 6 spots outside cell ; spot above vein 6. 
In my series of montana, thé spots outside celi vary from 4 
to 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 | 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. 
2 sinhala has a very minute white streak, or narrow spot, 
seldom over 2 mm. in length.
