Show 560 MR. H. H. DRUCE ON BORNEAN LYC^ENIDJE. [June 18, I have not seen this species, the female only of which is described. W e possess specimens from Nias I. which are referred to 67. symethus, but which possibly are 67. petronius if this should prove to be a distinct species. GERYDUS INNOCENS, sp. n. (Plate XXXI. fig. 4 d •) Miletus innocens, Staud. M S . d . Upperside: fore wing white, the apical half and outer margin to anal angle black, greyish along the costa to about the middle of the cell: bind wing white, slightly tinged with greyish ; costal margin broadly black ; anal and outer margins narrowly dusted with blackish brown, darkest at the tips of the nervules. Underside: ground-colour pale grey, with dark chocolate markings and spots arranged much as in 67. symethus, but the short band near the apex of the fore wing straighter and broader and the basal streak below the cell ending abruptly where it meets the white, just beyond the base of the lower median nervule, not running along the nervules as in G. symethus. 2 • Upperside differs only from male by the wdiite area of the fore wing being slightly more extensive, by the purer white of the hind wing, which has the outer margin dentated rather more strongly than G. symethus d , the cilia only being fuscous. Underside as male, but with the white discal area slightly larger. Expanse, d 14, $ 1| inch. Kina Balu ( Waterstr.). Types Mus. Staud. G. innocens is much like 67. gigantes on the upperside, but is very different below, and the dentated outer margin of the hind wing of the female also distinguishes it. The swollen base to the third mediau of the fore wing in the male, which is present, so far as I know, in all other species of the genus, is entirely wanting, in 67. innocens. The coloration of the underside is quite different from 67. symethus. Dr. Staudinger has sent m e a pair of this interesting butterfly. GERYDUS BIGGSII. Gerydus biggsii, Distant, Rhop. Malay, p. 206, pi. xxii. fig. 12, $ (1884). Gerydus gopara, de Nicev. Butt. India etc. iii. p. 25 (1890). Kina Balu (Waterstr.); Saudakan (Pryer); Labuan (Low and Wahnes). Tbis is a somewhat puzzling species, as it appears to vary considerably in the width of tbe white band on the fore wing: in males from Sandakan and Kina Balu it is shortest and narrowest, and in one specimen in Messrs. Godman and Salvin's collection is practically reduced to a median patch, being almost all below- the third median nervule ; in a male from Labuan in Dr. Staudinger's collection it is broad and long aud the basal area is much paler than usual. The females before m e from Kina Balu are much like the male noted above from Labuan and present a very different appearance from Mr. Distant's figure. |
