Observed in a tour through India and Ocylon. 97 
expedition. Alas for the once fair road, now a foot deep 
in white dust ! | 
December 19th. From Riang by way of Mongpu and 
Sareil back to Darjiling. This was such along march that 
little time could be given to collecting, moreover many 
hours were spent passing along a beautiful forest track in 
the deep afternoon shadow of the mountain. At the start, 
close to the river, the silvery-white Acropteris vagata, 
Moore, was conspicuously spread out upon a leaf, this was 
the only Uraniid that I met with. Near Mongpu, at about 
3000 feet, Hrgolis merione was very common about Ricinus, 
the castor-oil plant, upon which its larva feeds. A little 
higher up I came across Ticherra acte, Moore, a Lyczenid 
with very long tails that wave with the wind; it has a 
swift jerky flight. The hind-wing of this species is much 
plaited but the anal lobe is rudimentary. 
Other captures were Huphina nerissa, a male; Ganoris 
canidia, a female with all the hind margin of the hind- 
wing gone; Zachyris hippo, Cr..a male; Arhopala rama, 
Koll. ; Neptis astola, Moore; Llerda epicles, Godart, with all 
the hinder part of the secondary apparently bitten off by a 
lizard ; Cirrochroa aoris, Dbl., which I had seen at Pashék 
on the previous day ; Lethe rohria, very like P. xgeria in its 
habits and liking for partial shade; and Argynnis niphe, 
this last in the cinchona plantation at about 3600 feet. 
A large white butterfly, bright yellow underneath, flutter- 
ing at the sweet white flower of the cinchona led me to 
dismount, and it was well that I did so, for it turned out 
to be Prioneris thestylis, Dbl., and fortunately a female, 
which must be very much the less common sex, at any rate 
the Hope Collection contained no female of the genus. 
The next day, December 20th, I rode down to the 
Ranjit River, the boundary of Sikkim, the great Papilio 
country. Distance however reduced my actual collecting 
to less than four hours. 
At about 3000 feet I took two of the Erycinid Zemeros 
Jlegyas, also Symbrenthia hyppoclus. The chief collecting- 
ground was near the suspension bridge leading into 
Independent Sikkim, closed this year to all Europeans, 
including entomologists, on account of the Tibetan difficulty. 
It was trying to one’s European temper to be stopped by 
a coloured policeman, while natives passed freely over! 
Here, some 8000 feet above the sea, the first thing that 
I happened upon was Limnas chrysippus in extreme
