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.

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.

 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 band is also wider, which makes 

 the spots at the a])ex 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.

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 my collection. This species 

 was incorrectly identified in my 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.
