Show 1888.] LEPIDOPTERA O F JAPAN A N D COREA. 637 This species is allied to D. fasciata, but the different coloration and the shape of central fascia, which in D. approximans is much attenuated towards inner margin, and has its outer edge twice indented, readily separates the two species. The secondaries in both sexes are also much darker than in D. fasciata. Several specimens, coll. Pryer (No. 238). Yokohama (Pryer). 265. ROSAMA PLUSIOIDES. Rosamaplusioides, Moore, Desc. Ind. Lep. Atk. i. p. 62 (1879). Ptilodontis ornata, Oberth. Etud. d'Entom. x. p. 15, pl. ii. fig. 5 (1884). Two examples in Pryer's collection, placed with the Liparidae and labelled " 167. OrgyiaX sp." Japan (Pryer) • Darjeeling ; Sidemi. 266. ROSAMA CINNAMOMEA, sp. n. (Plate XXXI. fig. 11.) rf . Primaries cinnamon-brown, streaked with darker from apex to centre of wing, and with ill-defined darker basal and discal lines. Apical and discal spots blackish. Secondaries fuscous brown. Head, palpi, and thora.x dark brown; abdomen fuscous. Under surface of primaries brown with paler margins ; secondaries and abdomen yellowish grey. Expanse 33-35 millim. I took an example at Nagasaki in June, and there was one in Pryer's collection. Nagasaki (Leech) ; Ohoyama (Pryer). 267. ROSAMA MACRODONTA. Rosama macrodonta, Butl. Cist. Ent. vol. iii. p. 127 (1885). One example, coll. Pryer. Japan (Pryer). 268. PTILODONTIS PLUSIOTIS. Ptilodontis plusiotis, Oberth. Etud. d'Entom. v. p. 65, pl. vii. fig. 3 (1880). . A female example at Gensan in July ; two males, coll. Pryer. The three specimens agree well each with the other, but neither of them are quite like Oberthiir's figure of his P. plusiotis ; however, as my insect has been identified by Herr Banghaas as that species, I am content to let it stand as such, especially as I have not seen Oberthiir's type.
