THE BUTTERFLIES OF CEYLON 13 
If disturbed, it flies away rapidly, but soon settles again. 
Its wings are very fragile, and it is easily damaged by the net. 
It comes readily to toddy, etc. 
February and August are, in my experience, the best 
months for fresh-hatched specimens, but a few may be taken 
all the year round. 
Localities : Nuwara Eliya, Horton Plains, Ohiya, etc. 
23. YPTHIMASINGALA, M., DeN., Ypthima avanta singala, 
B. Ypthima (Thymipa) avanta singala, E. 
Also found in India. 
Y. avanta is found in the Western Himalayas and Burmah. 
It differs from simgalain having a sex mark on the fore wing 
of the male, and very conspicuous transverse dark fascize 
on the under side. 
Moore also gives Y. thora, but it is certainly only a variety. 
It differs only in having a minute sub-apical bi-pupilled 
ocellus on the upper side of the fore wing of the male. 
The number of ocelli on the under side of the hind wing 
varies in my specimens from 4 to 7, and is not always the 
same on both wings. They also vary as much in size as in 
number ; but this does not seem to depend on season or 
climate, except that I have only taken a variety with the 
ocelli reduced to mere specks at the highest elevations. 
Specimens from Elpitiya, near Galle, taken during the 
rains, agree very well with those taken at Haldummulla 
during the drought, except that var. thora was proportion- 
ately more abundant at the lower elevation. 
Common all over the Uva patanas from 500 to over 5,000 
feet ; Galaha, near Kandy ; and Elpitiya, near Galle. Flies 
all the year round at Haldummulla. 
24. YPTHIMA CEYLONICA, M., DeN., E.; Ypthima huebneri 
ceylonica, B. 
Also found in S. India. 
Y. huebneri, which is foundin India, Burniah, Malaya, etc., 
differs in having the whole of the upper side of the hind wing 
brown. De Nicéville says of ceylonica that: “In the Orissa 
specimens the striation of the ‘‘under sides is denser, and
