species is probably a straggler at Jalpaiguri, its head-quarters being 

 almost certainly in the rich Terai forest at the foot of the hills. 



31-4. Arehopala aeama, de Nic^ville. 



I have a single male of this species from Sikhim in my collec- 

 tion, but do not know when it was captured or the exact locality. 

 Major C. T. Bingham took a second specimen in May on the road from 

 Kalimpong to Padong at 4,700 feet. Mr. Dudgeon possesses a single 

 female taken at a low elevation in September. It must be very rare 

 in the Eastern Himalayas, and is found also in Burmah. 



315. Aerhopala amantes, Hewitson. 



Occurs not uncommonly in the Terai and low on the hills. 



316. Aeehopala abseus, Hewitson. 



Common up to 9,000 feet, and flies from June to December. The 

 larva feeds on the leaves of the sal tree, and is attended by the ant, 

 (Ecophylla smaragdina, Fabricius. 



317. Aerhopala (enea, Hewitson. 



A rare species in Sikhim ; has been recorded from low elevations 

 from October to December and again in February. 



318. Arehopala atkax, Hewitson. 



A true plains' species, but occurs in the Sikhim Terai and low 

 valleys up to 3,000 feet, from April to October. 



319. Aerhopala singla, de Niceville. 



A very rare species in Sikhim and found from 1,500 up to 5,000 

 feet in May and June. It seems not quite so scarce to the east of 

 the Tista river, and has been taken in Upper Burmah. 



320. Aeehopala teesta, de Niceville. 



Very similar to, though quite distinct from, xi. singla, de 

 Niceville, and is much the more common sjDecies of the two in 

 Sikhim, and occurs with it at low elevations. This species may be 

 the same as x\. tiirbata, Butler, described from Nikko in Japan, but I 

 have not been able to compare males of the two species. A. teesta 

 has a wide range, being found not only in Sikhim, Assam, and Burmah, 

 but also in Sumatra and Java. 



321. Aeehopala eama, Kollar. 



Occurs in Sikhim at low elevations from April to October, and is 

 rather rare. It is found also at Kiukiang in Central China. 



322. Aerhopala asoka, de Niceville. 



A common species at low elevations from June to October. 



323. Aeehopala adeiana, de Niceville. 



Occurs at the same elevations and seasons as A. asoka, de Niceville, 

 and is even more common. It is found also in the Chin-Lushai Hills.
