1882.] MR. H. J. ELWKS ON BUTTERFLIES FROM SIKKIM. 405 



same time and place. C. pumilus was found by the late Dr. Stoliczka 

 on the Lanak Pass (1.t,500 feet) in Ladak, and has never been 

 taken by any one else as far as I know. There are no specimens of it 

 in English collections that Mr. Moore or 1 have seen. 



Debts (T.4.nsima, Moore) masoni, n. sp. (Plate XXV. fig. 2.) 



Resembles Debis verma, KolL, in general appearance, size, form, 

 and colour, but distinguished on the upperside by a single white 

 spot near the apex of the fore wing, which is slightly undulate and 

 fringed white ; the anterior angle of the hind wing is bordered and 

 fringed white. On the underside there is one ocellus close to the 

 white spot near the apex of fore wing, and the ground-colour of the 

 hind wings is overlaid with greyish scales, and without the transverse 

 steely bands of D. verma. The ocelli resemble those of D. verma iu 

 number, size, and position, but are ringed with hair-brown instead of 

 fulvous. The sexes do not differ. 



Of this species, which, though allied to D. verma and to D. isana, 

 Koll., is very distinct, I received a large number of specimens, which 

 do not vary. As this insect has never been taken before, I imagine 

 it to be from the Chumbi valley, on the other side of the passes, but 

 it is probably not found at extreme elevations. 



Lethe (?) margarit^, n. sp. (Plate XXV. fig. 1.) 



A single male specimen of this fine and distinct species was in the 

 collection, and appears very distinct from any thing which has been 

 described. At first sight it seems most nearly allied to Neorina hilda, 

 but does not quite agree with that species in neuration. ]S^either 

 does it agree exactly with either Zophoessa or Lethe, though it 

 somewhat resembles L. lunaris, Butler, in markings. Until we know 

 more of the insect, it will be best to leave it in the genus Lethe, 

 which requires careful revision, as the species at present comprised in 

 it are very varied. 



Antennae in size and shape like those of N. hilda, rufous with 

 reddish tip. Palpi longer, more pointed, and less hairy than in N, 

 hilda. Abdomen and legs rather shorter. 



Colour hair-brown, paler beneath, with a transverse pale fawn- 

 coloured band beyond the disk, well defined on underside and fainter 

 above. A similar band near the margin of the wing at an acute 

 angle to the first, enclosing five white-pupilled ocelli in a straight 

 row. On the exterior margin are two narrow lines of similar colour to 

 the bands. Pattern of hind wings beneath somewhat similar, but 

 the transverse band is rather curved outwards, and there is a large 

 ocellus between the first and second subcostal nervule. The ocellus 

 at anal angle has a double pupil. The bands on hind wing do not 

 show on the upperside, and the ocelli are indistinct. 



Expanse 31 inches. 



Neorina hilda, Doubl. & Westw. Gen. D. L. p. 369, t. 65. fig. 2. 



A single male specimen of this fine species, taken probably in the 

 lower valleys of the interior, was in the collection.
