BUTTERFLIES COLLECTED IN THE TAVOY DISTRICT, 127 
269. Arhopala aida, DeN. 
A male and two females taken, the male at Yeawing on 27th February 
1919 and the females on Kalataung, 1,700’, on 21st December 1919. 
Female. Expanse 1‘6—1°'8 inches. 
Upperside ; Forewing bright rich purple, the costal margin very broadly, 
increasingly to the apex, thence decreasingly to the anal angle, black; a 
black spot on the disco-cellulars. Hindwing, the costal margin very widely, 
the exterior margin less so, black, abdominal margin broadly pale fuscus, 
anal lobe black with a tuft of white hair at the apex: tail black, tipped with 
white. The margins of the hindwings are very wide so that the purple colour 
is confined to the middle portion and appears as a large spot. Underside as in 
male. 
270. Arhopala vihara, Felder. 
A single male taken at Yeawing, 300’, in February 1919. 
270. Arhopala silhetensis, Hew. 
Two males and a female of this rare species were taken. A male on Saba- 
taung, 300’, in January 1920, one in Mergui district in February and a 
female at Myekhanbaw in April 1920. These specimens agree exactly with 
A. arama, DeN., which Bethune Baker places as a synonym of siihetensis. 
The males are darker than the Sikkim specimens in my collection, but the 
black borders are narrower. 
272. Arhopala anthelus, Db. & Hew. 
Several males and females of this magnificent species were taken at Kala- 
chaung in April 1919, and also on Kalataung, 1,500’, during the last week 
of December 1919. 
273. Arhopala subfasciata, Moore. 
Very common everywhere in heavy forest, but good specimens are 
difficult to get. 
274. Arhepala agata, Hew. 
Rather a common species, found on the hills in heavy forest. Numerous 
specimens of both sexes were taken at Pagaye, Kalataung and Sabataung 
during December 1919. 
275. Arhopala selta, Hew. 
A rare species of which I took a female at Yeawing, 300’, on 28th 
February 1919, a pair on Kalataung, 1,700’, and a male at Pagaye, 600’, 
during December 1919. 
276. Arhopala rafflesii, DeN. 
Two males only taken ; one in the Mergui district in February and the 
other at Kalachaung in March 1919. 
277. Arhopala aroa, Hew. 
Five males and four females were taken on Kalataung, 1,500’, on 22nd 
December 1919 and a few at Pagaye and Myekhanbaw during December 
and April respectively. 
278. Arhopaia atosia aricia, Std. 
Three males and two females taken during December and January 1919- 
20 ; a female at Pagaye, 600’, a pair on Kambauk hill, 500’, and two males 
at Yeawing, 300’. 
279. Arhopala moolaiana, Moore. 
This species was quite plentiful on the hill to the east of Yeawing 
during February 1919. I also took many specimens at Pagaye, Wagon and 
Kambauk, in December and January 1919-20. During the heat of the day 
they descend to the streams and settle on damp patches of sand. 
280. Arhopala antimuta, Felder. 
A single female taken on Kalataung, 1,700’, on 22nd December 1919.
