Show 1892.] ON BUTTERFLIES FROM THE NAGA HILLS, ETC. 617 to a foliated tree, having a stony kernel. They were often observed foraging in company with Hylobales syndactylus, but with this exception they were never seen along with other Monkeys. One individual, which was taken alive, proved to be wild and untamable. 3. O n Butterflies collected by Mr. W . Doherty in the Naga and Karen Hills and in Perak.-Part II.1 By H E N RY J. E L W E S , F.Z.S. [Received December 5, 1892.] (Plates XLIII. & XLIV.) Fam. LYCJENID/E, GERYDUS SYMETHUS. Pap. symethus, Cram. Pap. Ex. ii. t. cxlix. B, C (1777). Gerydus symethus, Butt. Ind. iii. p. 22. Symetha pandu, Horsf. Cat. E. I. C. ii. 2 a, b (1828). 1 Miletus zinckeni, Feld. Reise Nov. p. 284, t. 35. fig. 34. Specimens from Perak, as well as others from Pulo Laut, Borneo, have a bluish tinge, which is not evident in Javan examples, and both sexes are much darker on the wings than specimens from Nias, which may be a local race, though they agree on the underside. I cannot see how to distinguish M. zinckeni, Feld., from Java. GERYDUS BIGGSII. ? Gerydus biggsii, Dist. Rhop. Mai. p. 206, t. xxii. 12 $ (1884) ; Butt. Ind. iii. p. 24. 1 Gerydus gopara, de Niceville, Butt. Ind. iii. p. 25 3 (1890) ; id. Journ. Bomb. Nat. Hist. Soc. vol. v. p. 208. n. 8, pi. E. figs. 1 3, 2 2 (1890). Several specimens from Perak agree with others from Sumatra, Nias, and Pulo Laut, one of which is marked biyysii $ by Doherty. I have little doubt that these are the same species as de Niceviile described from Perak, which he distinguishes from biggsii (of which he had not seen the type) by the distinctness of the markings below. Neither Distant's figure nor his description is clear enough to identify his species, which came from Malacca; and there is some variation in the markings of both the upper and underside among my specimens. GERYDUS HERACLEON. Gerydus heracleon, Doh. J. A. S. B. Ix. pt. ii. no. 1, p. 36 (1891). The type of this species, from Perak, is like the last but larger, and with the markings below more like those of G. symethus. i For Part I. see P. Z. S. 1891, p. 249. |
