Mr. W. L. Distant on Malayan Entomology. 199 



museum, who, acting on the initiative of my friend Mr. Lionel 

 de Niceville, most considerately forwarded a complete set of 

 specimens to London to aid me in rendering my ' Rhopalo- 

 cera Malayana ' as comprehensive as existing materials will 

 allow it to be made in that direction. It is by such 

 help (and I have received much unexpected and valuable 

 assistance from other quarters) that faunistic publications can 

 be encouraged and that the maximum of such work may be 

 completed by a proper division of labour. 



The species here described will be all subsequently figured. 



Ehopaloceea. 



Fam. Nymphalidae. 



Subfam. Ntmfhalin^. 



Chersonesia peraha, n. sp. 



Allied to C. rahria^ Moore, but smaller, the ground-colour 

 more ochraceous and less rufous ; markings similar, but with 

 the transverse fascia broader, much darker, and placed closer 

 together. The obsolete caudate prolongations in C. rahria 

 near the apices of the first and third median nervules are 

 scarcely visible in C. ijeraka^ and a structural peculiarity 

 exists in the first subcostal nervule of the anterior wings, which, 

 in the species I here describe, impinges near its base on the 

 costal nervure. 



Exp. wings, $ 28 millim., ? 34 millim. 



Hah. Perak {Kunstler^ Calcutta Mus.). 



Tanaecia Nicevilleij n. sp. 



Male. Wings above very dark brownish, with a violaceous 

 tinge ; anterior wings with the cell crossed by two basal 

 black lines, continued beneath to the median nervure, two black 

 lines near middle of cell, the innermost of which has a parallel 

 line between the lower median nervule and the submedian 

 nervure, and a single black line at end of cell ; a small bluish 

 spot near apex and a marginal bluish fascia commencino- 

 about centre of wing and gradually widening to outer angle, 

 where it possesses two inner lanceolate black spots margined 

 with bluish beneath the lower median nervule, and an inner 

 black streak at inner margin : posterior wings with a very 

 broad outer marginal bluish fascia, narrowest at apex of wing, 

 inwardly margined with small blackish spots, and containing 

 a central series of blackish spots placed between the nervules, 

 which become practically obsolete at the area of the median 

 nervules ; three obscure blackish lines crossing cell^ two near
