Show 386 MR. H. J. ELWES ON S O M E [May 6, and abdomen tinged with steel-blue, which also extends to the base of the fore wings. Hinder part of abdomen clothed with some scattered white hairs. The haustellum bright red, looking, when rolled up, like a red spot below the neck. Of this curious and distinct species I received two specimens only, from the late Otto Moller in 1887. As they have neither date nor locality, I presume they were taken in the interior of Sikkim by his native collectors. RETINA? FUSCESCENS. (Plate XXXII. fig. 12, $.) Of this very distinct species I have a single specimen only, of which the antennae are not perfect and the wings somewhat worn; but though I cannot be certain of the genus, yet the insect can be confounded with no other known to Mr. Moore or myself from the Indian region l. The venation seems near that of Retina rubrivitta, though in this family I do not attach so much importance to that character. The antennae are somewhat less pectinated though similar in structure. The projecting organ which resembles an ovipositor, and the red neck and the character of the wing-scales, all tend to prove that it belongs to the Cbalcosiidae, though its superficial appearance might lead one to place it among the Lithosiidae. Colour dull black, with a large whitish patch from the base to beyond the middle of hind wing. Tip of fore wing and costa of hind wing below also whitish. Collar and shoulders beneath red. Head, legs, and body black. Expanse 33 m m . Described from a single specimen taken in the interior of Sikkim by one of Mdller's collectors. RETINA? FLAVICOSTA, n. sp. (Plate XXXII. fig. 1, $ .) Of this insect I had a single female in the same collection as the last. It seems to be most nearly allied to R. rubrivitta, Wk. Cat. Het. ii. p. 439 (1854) ; Butl. 111. Het. v. p. 25, t. 84. fig. 4. Fore and hind wings dull black, with the costa of both wings and outer margin of hind wing dull yellow ; collar and sides of neck below crimson. Thorax and body apparently tinged with green, but the specimen is too much rubbed to be certain; antennae wanting. Genus ELCYSMA, Butl. Trans. Ent. Soc. 1881, p. 4. E L C Y S M A D O H E R T Y I , n. sp. (Plate X X X I V . fig. 4, <3.) This remarkable species is very nearly allied to E. westwoodi, Voll., from Japan, which is figured in the Tijdschrift for 1863, t. ix. fig. 3, o" > and described at page 136, of which E. translucida, Butl., 1 After describing this species I saw it in Dr. Staudinger's collection, and found that it was the same as Soritia fuscescens, Moore, Atk. p. 16 (1879). The male differs in having the hind wing without white, only a paler brown in the centre, and in being smaller. The antennae are very long, measuring -40 of an inch, which is the same a» the length of the hind wings. Both sexes are in the Atkinson collection. |
