NYTHA. 115 



S 2 • This form so closely resembles N. thelephassa that, but 

 for the remarkable difference in the S secondary sex-mark, it 

 might be mistaken for a rather dark variety of that insect. The 

 ground-colour on the upper side and on the basal half of the hind 

 wing on the underside is much darker, and the two white dots 

 lying between the ocelli on the upperside of the fore wing are 

 rarely present. The secondary sex-mark in the S is a dark band 

 of scales concolorous with the ground-colour and placed on either 

 side of the median vein on the upperside of the fore wing. 



Exp. S 2 60-65 mm. (2-4-2-6"). 



Hab. N.W. Himalayas, Spiti, Kunawar. 



Race lehana, Moore. — Differs from typical N. baldiva as 

 follows : — Ground-colour paler, the ochraceous postdiscal band 

 crossing the wings very much broader, and the black subtornal 

 spot within the ochraceous band on the upperside of the hind 

 wing absent. Male secondary sex-mark as in N. baldiva. 



Exp. S 2 62-68 mm. (2-45-2-7"). 



Hab. Ladak, Hunza, Chitral.

S . Upperside dusky-brown, a subterminal, indistinct, darker 

 line on both fore and hind wing ; cilia white, brown at the apices 

 of the veins. Fore wing broad, dusky-fulvous, short streaks in 

 middle of interspaces 1 to 5, the streaks in second and fifth 

 bearing each a white-centred black ocellus. Hind wing with 

 postdiscal broad similar streaks not reaching termen in inter- 

 spaces 2 to 6, these streaks palest inwardly, that in 2 bearing a 

 small white-centred ocellus near its apex. Underside : fore wing — 

 basal portion to apex of cell ochraceous yellow ; remainder not 

 reaching costa and termen paler ; costa, apex broadly and termen 

 irrorated with brown and white scales which extend into the cell ; 

 discocellulars defined by a short brown line ; ocelli as on upper- 

 side. Hind wing : basal half darkened by a dense powdering of 

 ochraceous and black scales, the highly sinuous outer border of the 

 dark portion abruptly defined by a broad irregular white band, 

 beyond which the wing darkens to the termen. Antenna?, head, 

 thorax and abdomen brown. 



Exp. <5 54-64 mm. (2-1-2-51"). 



Hab. N.W. Himalayas. 



Recorded from the basin of the Ravi by Mr. A. Graham-Young.
