Show 1895.] MR. H. H. DRUCE O N BORNEAN LYCJENIDJE. 561 GERYDUS PHILIPPUS. Miletus philippus, Staud. Lep. Palaw. p. 92, pi. i. fig. 2 (1889). Gerydus irroratus \ Semper (nee Druce), Schmett. Phil. Insel p. 162, pi. xxxi. figs. 10, 11, 12 (1889). Labuan (Low and Wahnes). Both sexes of this species from Borneo agree exactly with Herr Semper's figures. Dr. Staudinger has kindly sent me his types for examination, and I quite agree with Herr Semper (vide Supp. Schmett. Phil. Insel.) that they are conspecific; but as irroratus, Druce, falls before boisduvali, Moore, Dr. Staudinger's name must stand. Dr. Staudinger possesses a female from S.E. Borneo, near Banjar-masin, taken by Wahnes, which may possibly represent another species, as the band on the upperside is very narrow and obscured and the underside is of a reddish-brown hue; but without seeing a male I do not care to describe it. The specimen referred to M. zinkenii, Feld., by Mr. Herbert Druce (P. Z. S. 1873, p. 348), is an example of 67. philippus. GERYDUS VINCULA, sp. n. (Plate XXXI. figs. 9 d , 10 2 •)• d • Upperside uniform dull brown, with a pale oval spot at the base of the third median nervule of the fore wing, which just surrounds the swollen portion of the vein. Underside much like that of G. philippus but paler, and with a submarginal band of confluent markings extending from the apex to the outer angle of the fore wing and with the marginal spots very indistinct. 2 • Form of G.philippus : upperside uniform dull brown without markings ; underside as male. Expanse, d lyo", 2 lyV incn- Borneo. This obscure species is, I believe, the only one of the genus which has the ultra-median band on the underside of the fore wing extending across the wing to the anal angle-it usually ends somewhere about the third median nervule ; the sombre colouring of the female is also unusual. The types are iu Messrs. Godman and Salvin's collection, the male received from Dr. Staudinger and the female formerly in Bates's cabinet, neither being exactly localized2. PARAGERYDUS, Distant. PARAGERYDUS HORSFIELDI. Miletus horsfieldi, Moore, Horsf. & Moore, Cat. Lep. Mus. 1 I have carefully examined the type of Mr. Herbert Druce's Miletus irroratus, which is in Messrs. Godman and Salvin's collection, and find that it is quite impossible to separate it from G. boisduvali, Moore. 2 I have not included the Megalopalpus simplex, described by Herr Rober (' Iris,' i. p. 51, pi. iv. f. 1. 1885) from Borneo, as I a m of opinion that it is an African species closely allied to, or identical with, the Pentila zymna, Doub.. Hew. I have not seen M. simplex, and judge from the figure only, which is from a photograph. PROC. ZOOL. Soc-1895, No. XXXVI. 36 |
