subterminal series of black spots most of them transversely linear, 

 but the spots iu interspace 6 of the inner series and that in 

 interspace 2 of the outer series very large, round and prominent ; 

 these are followed by a very slender jet-black anticiliary .line. 

 Cilia of both fore and hind wings brown. Antennae black, shafts 

 obscurely speckled with white ; head, thorax and abdomen dark 

 brown, slightly purplish on the thorax ; beneath : palpi fringed 

 with black hairs, thorax and abdomen white. $ . Unknown.

c? . Upperside : purple with a frosted silvery-blue sheen very 

 much as in N. macropliihalma. Pore wing : a slender black 

 anticiliary line. Hind wing : costal and dorsal margins somewhat 

 broadly dull brown, an anticiliary black line as on the fore wing ; 

 the subterminal black spots in interspaces 1 and 2 of the underside 

 apparent in most specimens by transparency. Underside: ground- 

 colour and markings similar to those of N. macrophthalma but

a narrow edging of pale brown along the dorsal margin ; rest of

 wing: pale brown, much paler than the brown on the fore wing ; 

 base very obscurely shot with iridescent blue ; costal and dorsal 

 margins brownish white ; a transverse subterminal series of black 

 spots edged inwardly arid outwardly with slender white lines, two 

 minute spots in interspace 1 geminate, that in interspace 2 large, 

 these three crowned inwardly beyond the white edging with an 

 additional dusky spot. Underside : very similar to that of the J , 

 ground-colour paler, transverse white strigae broader. Both c? and 

 5 have the basal area of the fore wing within the transverse 

 white strigae lining the inner side of the discocellulars immaculate, 

 as in N. macrophthalma and N. kerriana.
