CEYLON BUTTERFLIES. 161 
are, I believe, almost entirely composed of 7’. distans and 
atticus, but one specimen I succeeded in catching proved to 
be U. folus. In May, 1917, they were exceptionally numerous, 
and all I caught, or saw settled, were 7’. distans. When not 
flighting, it only flies a short distance, and settles. with its 
wings expanded, usually on the under side of a leaf, but often 
in the most conspicuous positions. 
“Has a wide range, from Colombo to Nuwara Eliya” (F. 
M. Mackwood). 
196. TacrapEes arricus.—Also found in India, Burma, 
Malaya, Dutch Indies, &ce. 
This is a very variable species ; as a rule, specimens from 
Kandy, Ratnapura, and other places in the wet zone are 
much smaller, and have less white, than those from the highest 
elevations. The marginal spots on the hind wing vary greatly 
in size, but the one at the end of vein 1 is usually the largest. 
The black spot in the cell on the under side of the hind wing 
is frequently missing. In my series the number of hyaline 
spots on the fore wing varies from 5 to 10, the lowest one in 
the cell, and those in interspaces 2 to 5 being sometimes 
obsolete. The clasp is figured on Pl. 3, fig. 8. I have noticed 
no variation in it so far, but have only been able to spare 
specimens for dissection from Kandy and Ratnapura (wet 
zone). 
It is much rarer at Haldummulla than distans, and far 
harder to catch, as it seldom seems to settle here. It is 
commoner at Haputale (5,000 feet), and I am told that it is 
abundant in Nuwara Eliya at times. I can get plenty from 
Kandy. 
“An up-country species, from Kandy upwards” (F. M. 
Mackwood). 
197. TarEna THWAITESI.—Also found in India, Burma, 
Malaya, &e. 
Elwes and Edwards divide this genus as follows :— 
“1. Upper lobe of clasp bifid at the apex = thwaitesi. 
“2. Upper lobe of clasp not bifid at the apex. 
“3. Upper lobe of clasp with three limbs, all of which are 
serrate. Similar to thwaitesi, but smaller and paler above = 
minuscula,
