NOTJSS ON BUTTERFLIES FROM THE NAG A HILLS. 51 



slightly broader and paler, beyond it three of the subapical ocelli of the 

 underside shew through as black spots on a pale ground of the same colour 

 as the discal band ; above these spots inclined inwards are two pale 

 brown diffuse spots in interspaces 6 and 7, the upper one minute. . Hind- 

 wing with all the spots more conspicuous than in the male, those in 

 interspaces 2 and 3 centred with white and distinctly encircled with 

 yellowish brown, that in interspace 4 indistinctly encircled with the same 

 colour and with no white pupil, those in interspaces 5 and 6 diffuse and 

 blind and not encircled with an outer ring. The geminate spot in inter- 

 space 1 on the underside does not show throvigh. 



Underside as in male but paler : f orewing, the discal band a little more 

 curved, broader and paler ; the area between it and the submarginal lines 

 near the tornal angle yellowish brown ; above which are four submarginal 

 spots placed on a lilacine ground in interspaces 3, 4, 5 and 6 ; the lower 

 three being black with white pupils, encircled with yellow and a narrow 

 outer ring of darker colour ; the upper spot lilacine with a dark outer ring. 

 Hindwing as in male but lighter and the yellow rings round the occelli 

 brighter. 



The male and female can at once be distinguished from the same sexes 

 of Lethe dinarbas as follows : — 



(1) In L. brisanda the discal band is directed towards a point on the 

 dorsum short of the tornal angle, whereas in L. dinarbas it is directed either 

 towards the tornal angle, or to a point on the termen above it. 



(2) The submarginal spots on the underside of the forewing in L. brisanda 

 are four, in L. dinarbas three. 



(8) The termen of the hindwing at vein 4 in L. brisanda is prolonged 

 into a more distinct tooth than in L. dinarbas and gives the wing a different 

 appearance. 



In addition to the above differences the female of L. brisanda has the 

 discal band narrow, pale-brown and curved, the female of L. dAnarbas has 

 it broad pure white and straight. 



29. Lethe confusa, Aurivillius.- — ^The wet season form is connnon at Kohima 

 from July to October and the dry season form which appears to be undes- 

 cribed was taken commonly from the foot of the hills up to 3,000 feet in 

 February and April. 



Description of the dry season form. — 



Upperside: the same as in the wat season form except thai: on tlie 

 hindwing the submarginal ocelli are more conspicuous and in some speci- 

 mens distinctly ringed with yellow. Underside : differs from the wet 

 season form as follows : the ground colour between the discal band and 

 the apex of the forewing and also that on the anterior sides of the discal 

 and discoidal bands rich chocolate brown, this colour filling the apex of the 

 ceJl; the rest of the wing grey brown ; the submarginal spots are partially
