I have little doubt that the four names quoted above 
are all synonymous of one species, though, without 
seeing Felder’s type, it is impossible to be certain. At 
any rate, we have only one species in Sikkim which can 
be made to fit any of them, and I have compared this 
with the types of alberta and dolopes in the British 
Museum. It is very rare in Sikkim and in Bhotan and 
in the Khasia hills. Myr. Gammie took a single female 
close to his house at 3800 ft. in the month of August ; 
Messrs. Knyvett and Méller’s native collectors took two 
or three specimens near Buxa, in Bhotan; and I took a 
single male myself near Cherra Punji in the Khasia 
hills, at the end of September, at about 2500 ft.

Debis mekara, Moore, Cat. Lep. E.1. C., p. 219 (1857); 
Butt. Ind., p. 148, t. xi., fig. 24, d 2. 
A common species in the low valleys, and up to 5000 ft., 
from March to November. It frequents bamboos, and 
when disturbed flies into the thick foliage, where it 
settles on a bamboo-stem with closed wings, and is 
difficult to see. Like several of its congeners, it prefers 
shady to sunny places,
