Lepidoptera of Sikkim. 397 
Moller’s collectors have never found it, so I presume it 
is an inhabitant of the zone of forest from 6—8000 ft. 
310. Hypolycena (Sinthusa) chandrana. 
Hypolycena chandrana, Moore, P. Z. 8., 1882, p. 249, 
t. xi., figs. 2, 2a, 3. 
Hypolycena Grotet, Moore, P. Z. 8., 1883, p. 527, 
b Six hie. ob. 
The type of chandrana, which I have examined in the 
British Museum, is said to come from Lahoul; but I 
think this locality must be a mistake, as the insect is a 
tropical one, and Lahoul is a cold elevated valley in 
the North-west Himalaya; but I have two specimens 
taken in the adjoining valley of Kulu, at 5000 ft., on 
August 13th, by Capt. Young. I cannot see any 
difference between it and what is named Grotet in the 
' British Museum collection, which is said to come from 
N.E. Bengal (Grote). I have, however, taken specimens 
of both sexes myself both in Sikkim and the Khasia 
hills. In the former district it was found in dense 
tropical jungle, at 2500 ft., in June and July; but it is 
out from March to October, and occurs up to 5000 ft. 
In the Khasia I found it among bushes in the more open 
country, at about 4000 ft., in September. A perfectly- 
fresh female taken here differs somewhat from the 
similar sex in Sikkim, but only in minor and variable 
characters; and I see no way of separating the Kulu, 
Sikkim, and Khasia specimens. Nothing is said by 
Moore on the subject, the descriptions of both species 
being nearly the same. 
311. Hypolycena (Sinthusa) nasaka. 
Thecla nasaka, Horsf., Cat. Lep. E.1.C., p. 91 (1829). 
Rare in Sikkim, at 1—5000 ft., during the rainy season. 
Does not differ from a Kangra specimen in my collection. 
312. Hypolycena erylus. 
Polyommatus erylus, Godt., Ene. Meth., ix., p. 638. 
Hypolycena erylus, Hew., Ill. Lyc., p. 49, t. xxi, 
figs: 1, ¢; 2, 4,.-2 (1866). 
Common at low elevations from April to December.
