Show ] 891 -1 THE NAGA AND KAREN HILLS AND PEKAK. 261 malsara, whilst one sent by Major Bingham from the Karen Hills in February is a perfect rudis. I think there can be no question of the seasonal dimorphism in this species. MYCALESIS SURKHA. M. surkha, Marsh. J. A. S. B. vol. Ii. pt. ii. p. 37, t. iv. fig. I d (1882); Butt. ind. i. p. 133. Afar. ustulata. M. ustulata, Dist. Entomologist, vol. xviii. p. 289 (1885); Rhop. Mai. p. 418, t. xii. fig. 16 cS. With the exception of the larger ocelli, broader transverse lilac band, and more distinct markings of the underside, in which, as Distant says, it forms a transition to the Javan M. oroates, Hew., I see nothing to distinguish M. ustulata, of which I have two pairs taken by Doherty at Perak in February, from surkha, which I have from lavoy. The difference is just that which might be expected to be produced by a damper and hotter climate, and I have little doubt that both forms will be found at different seasons iu the same locality, if the dry and wet seasons are well marked. MYCALESIS FUSCUM. Dasyomnia fuscum, Feld. Wien. ent. Mon. iv. p. 401 (1860). Mycalesis diniche, Hew. Ex. Butt. iii. Myc. t. iv. fig. 23 (1862). Mycalesis fusca, Dist. Rhop. Mai. p. 53, t. v. fig. 1 ? . Taken at Perak by Doherty, and also common in the island of Nias off the coast of Sumatra (Mogdiliani). MYCALESIS DOHERTYI, n. sp. (Plate XXVII. figs. 3 J, 4 $ .) Mr. Doherty sent a pair from the low country of Perak which seem to me, as to him, to belong to an undescribed species of the same group as the last, in which the base of the costal, median, and submedian veins are much swelled in both sexes, and the male has a tuft of fine silky hairs at the base of the hind wing covering a glandular patch. „,, d. Dark hair-brown above, with an ocellus near the apex of tore wing, another larger one below it. The hind wing has three small ocelli above and two larger ones below. Beneath, the wings are paler brown, with a faint broken pale transverse oblique band near the base, another distinct whitish one across both wings not reaching the inner margin of hind wing. Ocelli as above but more distinct, the upper one on the hind wing larger but not so large as the fourth and fifth, and two additional small ones at anal angle which do not show above. Below, the band of ocelli is edged on both sides with whitish, and there are two pale marginal zigzag lines of same colour. The female is hke the male but rather larger, paler above, and with rounder wings. |
