nervule and tlie sulmiedian uervure, and being narrowly crowned with orange, and 

 having a black edge. Cilia white, crossed by brown at the tips of tiie veins. 



Underside : more brownisli white than in N. knlriii, Druce, but the spots and 

 markings very similar in shape, but bright tawny. Posterior wings with all the spots 

 the same colour, thus differing from N. keiria, in which the two subcostal spots and 

 the spot in the cell are black. 



Female. — Upperside : both wings greyish brown, with large white spaces on the 

 disc suffused with pale blue in certain lights, a dark grey spot at the end of the cell. 

 and a row of similar contiguous spots across the disc, all situate in the white space. 

 On the posterior wings the white space is traversed by a grey spot in the cell, a 

 curved row outside the cell, another beyond it nearer the margin, and a .submarginal 

 row of grey spots, the spot between the lowest median nervule and the submedian 

 uervure being crowned with an orange band. 



Underside as in the mile. 



Expanse of wings : J inch.

Nearest to N. keiria Druce. The female is very different from that sex of keiria, 

 which is an uniform dull ashy brown-grey, with a patch of blue scales in the region 

 of the cell of the anterior wings. 



23. Nacaduba elsa sp. nov. 



Male. — Upperside: dull violaceous blue; both wings broadly bordered on the 

 outer margins, by dull greyish brown. 



Underside : brown. Anterior wings with two brownish white lines acro.ss the cell, 

 followed by five brownish white bands: the first, commencing on the first discoidal 

 nervule at the end of the cell, and the second, commencing a little below the costal 

 nervure, cross the wings rather obliquely to the inner margin, where the second 

 becomes confluent with the fourth band; the third band merges in the fourth on the 

 lowest submedian nervule ; the fourth and fifth hands cross the wings parallel to the 

 outer margin ; on either side of the fifth band is a row of darker brown bars, the outer- 

 most being followed, on the margin, by [lale tawny. Posterior wings with the inner 

 three-fourths crossed by a series of irregular ))ale tawny lines, and there is an 

 irregular row of submarginal brow'nish black lunules, of which the second and sixth 

 are the largest, all being bordered on each side with tawny markings ; there are 

 no tails. 



Expanse of wings : J inch. 



ffab. Amboina. 



I cannot find that it is allied to any described species ; in tlie shape of the wings 

 it resembles the genus Chilades or Zizera. 



24. Jamides seminiger sp. nov. 



Male. — Upperside: both wings black, centred with dark violet purple, which 

 colour extends over the cells on both wings and a short distance round. 



Underside: dull cinereous brown, with the usual sijots and markings scarcely 

 distinguishable from other species of the genus, but tlic wings are rather shorter and 

 rounder. 



Fkmale. — Uppernitle : dull cinereous lirowii ; on the posterior wings is an indis- 

 tinct submarginal row of darker spots, paitiallv surrounded by obscure grey.
