Mr. Moore has a specimen unnamed in his collection which he has placed next to Propachys, but the palpi and legs are utterly different from this genus. Superficially it resembles a Tyspanodes, but has short legs like those of a Lithosid moth; its habit and general aspect make me think it must belong to the Lithosiidee, in which also Dr. Staudinger concurs ; and as I am unable to make out the venation clearly without injuring the specimen, I have placed it here for the present. I have two pairs, which I took at light on July 7th, 1886, at the old bungalow at Rangyroon near Darjeeling, at about 5000 feet; also a male from Bhutan and another which agrees perfectly, from the Naga Hills, taken in September. 6" $ . Fore wings above pale red, with a black line from the base to the outer margin, and two faint short ones above this at the apex ; hind wings sooty black. Below, the fore wing is sooty black with the costal margin and fringes red, and a red tinge at the base and hind margin. Thorax, tegulae, base of the antennae, and front of head red. Palpi, legs, and abdomen black. The hind legs have a strong double spur on the last joint; there is a conspicuous haustellum. Antennae rather short and filiform, with fine setae at the joints. Expanse, rf 23-25 mm., $ 28-31 m m . K A T H A ? SEMIFUSCA, n. sp. (Plate XXXII. fig. 9.) According to Mr. Moore this belongs to the genus Katha (P. Z. S. 1878, p. 16), but I am unable to follow his minute subdivision of the Lithosiidee, and have no other species with which to compare it, except K. nigrifrons, which it resembles in size and shape. It comes, however, nearer to the figure of K. terminalis (P. Z. S. 1878, pi. i. fig. 14) in colour, but differs in the band of tbe fore wing being more than twice as broad. Fore wing fawn-colour, with a broad fuscous band not extending to the costa except at the apex, or to the outer margin. Hind wing pale straw-colour. Below as above, but the band paler and less defined. Head and thorax brown; neck, legs, and abdomen pale straw-colour. Expanse 32 m m . Described from a single specimen, which seems to be a male, taken by one of Mbller's men in the interior of Sikkim. N U D A R I A ? D U D G E O N I , n. sp. (Plate XXXII. fig. 10.) This species seems to come nearest to Nudaria margaritacea, Wk., but I am not at all sure that it is congeneric with the European Nudaria, the venation being obscure. Mr. Moore thinks it should form the type of a new genus, but there are too many ill-defined genera in the family already, as it seems to me. The species is very distinct from anything known to me or to Mr. Moore, and the figure is so good that I need hardly describe the colour. The fringes at apex of both fore and hind wings are much darker brown than the remainder, and all the markings of the underside are darker than above. The hind legs have a double spur on |
