male.

Moore, P. Z.8., 1882, p. 240. 
Quite a rare insect, and apparently only found at low 
elevations in Sikkim, though at Simla it occurs from 
4 to 7000 ft. I have never seen a female from Sikkim.

Not common in Sikkim at 8—4000 ft. during and after 
the rains. A specimen from the east side of the Tista, 
taken in March, is much smaller and paler in colour, 
forming an intermediate link with H. angustata. 
119. Precis whita. 
Papilio iphita, Cram., Pap. Ex., iii., p. ecix., fig. o, D 
(Pega): 
Precis iphita, Butt. Ind., p. 68, t. xix., fig. 84, 3. 
A very abundant species here as elsewhere in the 
wetter parts of India. Occurs up to 7 or 8000 ft., and 
all the year round. 
120. Junonia asterie. 
Papilio asterie, Linn., Syst. Nat., x., p. 472 (1758) ;

Papilio almana, Linn., l.c.; Butt. Ind., p. 68. 
Not rare at low levels at all seasons in the year. De 
Nicéville’s suggestion that the two insects above quoted 
are seasonal forms of each other is confirmed by Moller, 
and seems to be most probably correct, though the two 
forms do not seem to be invariable, or to occur only in 
the wet and dry seasons respectively.
