![Description of a new Species of the Genus Lestes. Lestes ridleyi, sp. n. S . Length of abdomen (without appendages) 48 mm., of hind wing 31 mm., pterostigma 2*75 to 3 mm. General colour dull bronze-green. Wmgs hyaline, iridescent, slightly tinged with brown at the tip. Two supplementary sectors between the subnodal and median sector, 18-19 post- nodals. The nodal sector begins in the seventh cell after the nodus in the fore wings, and in the sixth in the hind wings. Pteticulation and pterostigma black. Head. Lower lip dull yellowish brown, upper lip brown, rest of the upper part of the head bronze-coloured. Frothorax dull brown, with a small bronze transverse mark along its posterior margin, which is not indented. Thorax. Upper surface dark bronze-green, with an obscure paler line following the humeral suture. Sides and lower surface yellowish brown. Abdomen. First segment yellowish brown. The segments 2-7 have a roughened dorsal surface, which is brown-green with a fine yellowish-green basal ring ; ventral surface bluish green, the bronze extends laterally ; segments 8-10 smooth, bluish, pruinose. Anal appendages lost, but, if I remember rightly, these were also of a bluish colour. The male was taken in the same locality as the specimen of Fericnemis., at the foot of Gunong Inas. There is stated to be a female belonging to the same species, which I have not ex- amined, in the British Museum collection, taken by Mr. Bidley in Singapore. L. ridleyi is closely allied to L. orientalis Hagen, from Ceylon, and L. udeana Kruger, from Sumatra. It is sufficiently distin- guished from both by its size, being intermediate in this respect.
