Show 1892.] THE NAGA AND KAREN HILLS AND PERAK. 663 KERANA ARMATA. Astictopterus armatus, Druce, P. Z. S. 1873, p. 359, t. xxxiii. 7. Kerana armata, Dist. Rhop. Mai. p. 402, t. xxxv. 31. This fine species seems not uncommon at Perak, and according to a note of Doherty's the male gives out a pleasant aromatic smell. The female differs in being of a paler brown colour. KERANA DIOCLES. Nisoniades diocles, Moore, P. Z. S. 1865, p. 787. Kerana diocles, Dist. Rhop, Mai. p. 403, t. xxxiv. 8. Common at Perak. The female here differs from the male in being of a paler brown, which does not seem to be the case in my Sikkim specimens. KERANA AURIVITTATA. Plesioneura aurivittata, Moore, P. Z. S. 1878, p. 483. One specimen from the Karen Hills, one from the Naga Hills, and several from near Bernardmyo seem to belong to this species, which is distinguished from P. cameroni, not by the shape of the band, but by its colour, which is pale golden like that of P. dhanada, Moore, from which it is distinguished by the larger size and different shape. ? KERANA CAMERONI. ? Plesioneura cameroni, Dist. Ann. Nat. Hist. ser.5,x. p. 248(1882). Kerana aurivittata, var. cameroni, Dist. Rhop. Mai. p. 403, t. xxxiv. 19. Five specimens from Perak are easily distinguished from the last by the smaller size, different shape, and by the band being of a much deeper golden colour. The baud is also wider, which makes the spots at the apex look nearer to it than in K. aurivittata. The fringe of both wings also is plain and unspotted, whilst in the latter a small part of the fringe of the fore wing opposite the end of the band is pale as in K. dhanada. KERANA? DHANADA. Plesioneura dhanada, Moore, P. Z. S. 1865, p. 789. Three specimens from the Karen Hills which agree with one from Tenasserim and one from Khasia, in m y collection. This species was incorrectly identified in m y list of the Sikkim butterflies ; where I put it with a ? as a synonym of C. dan, but I have one specimen sent me by Moller from thence which differs in the band being much shorter outwardly and narrower on the costa. The underside, with the fringe of the hind wings, easily distinguishes this from either of the last two species. S A N C U S SUBFASCIATUS. Astictopterus subfasciatus, Moore, P. Z.
