Chilades? pontis', n. sp. 



Male above dull purplish black with faint green or (in some lights) 

 purple reflection, darker towards the body. Fringes alternated with 

 black and white. 



Beneath dull grey, with irregular darker markings, which on the 

 hind wing coalesce into a blackish patch powdered with grey on the 

 inner half of the wing. 



Body black, with grey hairs and palpi. Antennae faintly ringed, 

 with a short distinct club. 



Expanse ^ inch. 



The shape of the hind wing is very peculiar, the costal margin, 

 which is straight, forming almost a right angle with the outer 

 margin. I know of no other species in which the character is so 

 well marked. 



Described from three males (a fourth exists in Godman's collection 

 ex coll. Lidderdale) taken by me on May 27, 1886, on the bridge 

 crossing the Rangbi river on the way from Darjeeling to Mongpo, at 

 about 6000 feet elevation, in dense dripping evergreen-forest. 



This curious little insect is unlike anything found in India or the 

 Himalaya, but has a very near ally in China, which, as it is unde- 

 scribed, I will here characterize as follows : — 



Chilades sinensis, n. sp. 



Resembles C. pontis, but has a broad border of darker colour 

 than the -wings, no green reflections, and a rounder apex to the fore 

 wing. Beneath, the markings are very similar but more continuous, 

 and there is an outer band near the margin of the fore wing not 

 found in C. pontis. Tlie dark markings on the hind wing also 

 come nearer to tlie margin. 



Described from a specimen taken by Mr. H. Leech near Ningpo 

 in May 1886. This agrees perfectly with several others from 

 Kiukiang on the Yangtse river taken by Maries, which have for 

 some years been in the coUeclion of the British Museum. 



HyPOLYCiENA VIRGO, U. Sp. 



Female. Fore wing above black, with a large discal patch of French- 

 grey extending to the hind margin inwardly. Hind wing grey 

 powdered with black, and becoming dull black on the costal margin, 

 with a single narrow black tail tipped white, and a small fuscous lobe 

 at anal angle. Fiinges white, narrow towards the apex of fore wing. 



Beneath bright French-grey, with a distinct transverse sinuous 

 yellowish band, narrowly edged black on both sides about two thirds 

 of the length, not extending quite to the hinder margin ; a short 



^ I include this in the genus Chilades (Moore, Lep. Ceylon, i. p. 71) with 

 doubt. It seems, on a superficial examination, to have most afSnity to Chilades 

 laius. Cram. ; but vcithout sacrificing a specimen I cannot be sure that the 

 apparent resemblance is real. And many of Moore's distinctions are so trivial 

 that I do not think they can be adopted without an independent study, not only 

 of the insects in question, but of the whole of the Eastern Lycoenidce.
