Show 662 MR. H. J. EI.WES ON BUTTERFLIES FROM [DeC. 6, on the underside of hind wings, which are visible when carefully examined. ASTICTOPTERUS GEMMIFER. A. gemmifer, Butl. Trans. Linn. Soc, 2nd ser. Zool. i. p. 555 (1877). Kerana gemmifer, Dist. Rhop. Mai. i. p. 403, t. xxxiv. 29. I have this also from Perak, where it seems not uncommon. It agrees with specimens from Pulo Laut, Borneo. I cannot follow Distant in his generic separation of this species from the last. ASTICTOPTERUS LADANA. (Plate XLIII. fig. 4, 3 •) Carystus ladana, Butl. Trans. Ent. Soc. 1870, p. 502. Three specimens from Perak agree with the type from Borneo in the British Museum. Above they are very like A. gemmifer, but are easily distinguished by the yellow colour of the legs, palpi, and abdomen below, and by the orange tinge on the inner margin of the hind wings below. I do not know in what genus to put this species. Carystus is a name of Hiibner's adopted by Butler, who puts in the genus four South-American species. ASTICTOPTERUS SINDU. (Plate XLIII. fig. 3, 3.) A. sindu, Feld. Wien. ent. Mon. iv. p. 401 (1860). A single specimen of this small species from Perak has the band of the fore wing less developed than in specimens from Borneo. It is distinguished by the colour of the hind wing below, which is sprinkled with yellow scales, from A. xanites or A. gemmifer. ASTICTOPTERUS OLIVASCENS. A. olivascens, Moore, P. Z. S. 1878, p. 692. A. olivascens, Wood-Mason & de Nicev. J. A. S. B. 1886, pt. ii. p. 381, t. xviii. 2, 2 a $ . I believe there are two species confused under this name, of which one may be the A. jama of Felder; but what Distant calls A. jama, Rhop. Mai. p. 401, may be A. subfasciatus. The one is in the male sex plain unspotted black on both surfaces, with some green scales on the hind wing below; the female has two spots at the apex of the fore wing. I have it from Sikkim, Bhutan, the Khasia and Naga Hills, Margharita, the Shan Hills, Perak, and West Java. The other has the underside dull brown with some darker markings on the hind wing below, two or three glossy spots in both sexes near the apex and another below it beyond the cell. This I have from Burmah, the Karen and Shan Hills. ASTICTOPTERUS BUTLERI. A. butleri, Wood-Mason & de Nicev. J. A. S. B. 18H3 uf ii p. 98, t. x. 3 3 . ' ' Two males from Margharita. |
