384 Mr. H. J. Elwes’ catalogue of the 
259. Chilades ? pontis. (Pl. VIIL., fig. 5). 
Chilades pontis, Elwes, P. Z.§., 1887, p. 446. 
Of this curious little species I know four specimens 
only, of which one is unnamed in Mr. Godman’s col- 
lection, and the other three were taken by myself on the 
bridge over the Rangbi jhora, on the road from Darjeeling 
to Serail, at an elevation of 6000 ft., on May 27th, 1886. 
The locality was in the middle of a dense damp forest, and 
the insects settled on the wooden bridge which was carried 
away by the torrent during the heavy rain (twelve 
inches in eight hours) which occurred on the night of 
June 18th, and which caused much destruction to life 
and property at Mongpo. 
The illustration, which faithfully represents the species, 
makes a detailed description unnecessary, but I may say 
that it is most nearly allied to a species discovered by 
Maries at Kiukiang, in Central China, and described by 
me in P.Z.§., 1887, p. 446. From this, however, it is 
easily distinguished by the narrower border to the wings, 
which have a green reflection and less rounded apex. 
The markings beneath are very similar but less regular, 
and there is an extra band on the hind wing not found 
in the Chinese insect. 
260. Lampides elianus. 
Hesperia elianus, Fabr., Ent. Syst., ii., p. 280 (1798). 
Common up to 4000 ft. from March to December. 
261. Lampides elpis. 
Polyommatus elpis, God., Enc. Meth., ix., p. 654 (1823). 
Common with the last at the same elevation and 
seasons. 
262. Catochrysops strabo. 
Hesperia strabo, Fabr., Ent. Syst., ii., p. 287 (1798). 
Not so common as in the plains, but occurs up to 
8000 ft. from April to November. I took it below 
Mongpo in June.
