426 Mr. H. J. Elwes’ catalogue of the 
the pink lunules of the hind wing, and I think the 
abdominal fold is less developed in dasarada. I have 
not observed in this species the nauseous odour which, 
according to Wood-Mason, is characteristic of Philoaenus, 
but Mr. de Nicéville says it has the strongest smell of 
any butterfly he knows. The flight of this butterfly is 
much less swift than that of many Papilios. It may 
be seen sailing with a very soft, graceful flight along 
the edge of the clearings and round the flowering trees 
in the open places. A species of Albizzia is one of its 
favourite trees, but to get fresh specimens one must 
search for those which, having recently emerged from 
the pupa, may be found settled on the low herbage and 
flowers at the side of the forest-path.

Di. Lep., t. ii., fig. 3, ¢; Westw., Cat. Or. Ent., 
t. iv.a, fig. 3. 
This species seems to have a much wider range than 
the last, as I have specimens from Hazara, in the 
extreme N.W. Himalaya, to Mooleyit, in Tenasserim. 
It is common in Sikkim at the same elevations and in 
the same mouths as the last, but I am unable to say 
whether the species mix together. 
402. Papilio Janaka. 
Papilio Janaka, Moore, Cat. Lep. E. 1. C., 1, p. 97 
(1857); P. Z.8., 1857, p. 104, t. 45. 
2 P. sikkimensis, Wood-Mason, Ann. Nat. Hist., 1882, 
p- 103. 
A rather rare species in Sikkim, where it is found at 
3—5000 ft.in May and June. I am doubtful whether 
P. sikkimensis is really distinct or not. Mr. Wood- 
Mason describes it as having the fore wings and basal 
half of the hind wings of a greenish black, which is not 
the case in any specimens I have seen from Sikkim. He 
does not, however, give any comparison of it with Janaka, 
and as only one species is known to us in Sikkim to ~ 
which these two names can be applied, I cannot help .
