CEYLON BUTTERFLIES. +9) 
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. 
Satyrine. 
_ 13. Orsotri@Nna MANDATA, M.& De N.; Orsotricena meda 
mandata, B. & K.—Found also in Southern India. 
“ Tt differs from O. meda in the white discal band on the 
under side being very much broader, and proportionately more 
attenuate apically’ (Bingham). 
It is very common here nearly all the year round in grass by 
the road sides or near jungle, but it doesnot usually frequent 
the open patanas away fromjungle. It is common in growing 
paddy. 
It usually varies very little in the wet or dry seasons, or at 
high or low elevations. I have, however, one specimen caucht 
at Kumbukkan (500 feet) after a severe drought. 
In this the white band is only half the usual width, the ocelli . 
are much smaller, and the white marginal and sub-marginal 
bands on the hind wing are further apart. Others caught at 
the same time were quite normal. 
It is common all over the southern part of the Island from 
sea level to over 4,000 feet, but I have not yet seen it in the 
Northern or North-Central Provinces, 
It sometimes comes to sugar. 
“ Taken at Lindula, 5,000 feet, in October” (Ff. M. Mack- 
wood), 
14. CALYSISME PERSEUS.—Moore also gives C. blasius, 
which is the wet season form —Found in India, Burma, 
Malaya, Southern China, &c. Very common at Haldummulla 
on grass by the road sides, or on patanas, especially above 
3,000 feet. 
T have found it equally plentiful at Elpitiya, in the Southern 
Province, on patana very little above sea level, and have taken 
it at Galle and Kumbukkan (Uva, 500 feet). I have never seen 
it in the Northern Province.
