( 99 ) V. On a collection of Lepidoptera from Kiukiang. By John Henry Leech, B.A., F.L.S., F.Z.S., F.K.G.S., &c. [Read December 5th, 1888.] Plates VII., VIII., & IX. The materials for this paper were collected for me during the months of April, May, June, and July, 1887, by Mr. A. E. Pratt, in the neighbourhood of Kiukiang (which is situated on the Yangzee Eiver, about 500 miles from the sea). The collection is not rich in species, probably only representing about one-sixth part of the lepidopterous fauna ; it contains, however, a fair pro-portion of new species, and also many that have not hitherto been recorded from that region. The larger proportion of species are common to the eastern coast of China, and Japan, but many occur also in the Hima-layas. The chief point of interest in the collection is the variation exhibited in so many species, especially in Papilio Sarpedon and Melanargia halimede. 1. Euploea midamus, Linn. ; Kirby, Cat. Diurn. Lep., p. 15. Two examples only. 2. Lethe butleri, n. s. (PI. VEL, fig. 3). Wings in both sexes smoky brown, with their margins traversed by a slender pale band intersected by a line somewhat darker than the ground colour. Male. Outer third of primaries rather paler than rest of wing. One small ocellus near the tip. Towards the outer margin of secondaries are two or sometimes three ocelli, that nearest to the anal angle being the largest, and always havmg a white pupil, though this varies in size, and is scarcely visible in some specimens. Female. Larger than the male. Outer third of primaries paler. TRANS. ENT. SOO. LOND. 1889. — PAET I. (MARCH.) H 2
