Observed in a tour through India and Ceylon, 97 



expedition. Alas for the once fair road, now a foot deep 

 in white dust ! 



December 19th. From Riang by way of Mongpn and 

 Sareil bach to Darjiling. This was such a long 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 Acroptcris vagata, 

 Moore, was conspicuously spread out upon a leaf, this was 

 the only Uraniid that I met with. Near Mongpu, at about 

 3000 feet, Ergolis merionc was very common about Bicinus, 

 the castor-oil plant, upon which its larva feeds. A little 

 higher up I came across Ticherra acte, Moore, a Lycaenid 

 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 Hitplvina nerissa, a male ; Ganoris 

 canidia, a female with all the hind margin of the hind- 

 wing gone ; Tachyris hippo, Cr., a male ; Arhopala rama, 

 Koll. ; Neptis astola, Moore ; Uerda epicles, Godart, with all 

 the hinder part of the secondary apparently bitten off by a 

 lizard ; Cirrochroa aoris, Dbl, which I had seen at Pashok 

 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, Mutter- 

 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 

 fiegyas, also Symbrenthia hyppochis. 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 Zivinas chrysippus in extreme
