Show 1882.] MR. H. J. ELWES ON BUTTERFLIES FROM SIKKIM. 405 same time and place. C. pumilus was found by the late Dr. Stoliczka on the Lanak Pass (15,500 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 I have seen. DEBIS (TANSIMA, 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 in 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 (?) MARGARITA, 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. Neither 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 3*1 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. |
