As regards the females of the last three species the descriptions will 

 have to be consulted and, even then, they are not easily distinguish- 

 able. The size of the ocellus on the upperside of forewing and the 

 more or less light suffusion around it affords no criterion of difference, 

 being very variable in the same species. The wet-season forms have 

 the ocelli on the undersides of the wings very clearly defined, promi- 

 nent and large; the dry- season forms have them very much reduced 

 in size {vide PI. F, tfgs. 37 and 37a), sometimes mere black or white 

 dots, or even altogether wanting and the ground-colour of the whole 

 wings underneath shaded and variegated, sometimes dark, sometimes 

 light, generally with a dark transverse fascia or line from costa of 

 forewing after middle to the inner margin of hindwing before tornus; 

 in the wet-season the colour of the underside is uniform and dark, the 

 fascia being then sometimes white. 



Genus— LETHE.

with a conspicuous pale or purplish transverse 

 straight line (male upperside forewing with two 

 prominent white preapical spots ; female with a

 ?.-45" to 3" euroiya. 



B. Hindwing underside : basal half mottled and 



shaded with greyish-brown and purple, no dis- 

 tinct transverse line.

 without spots ; of female : with oblique white 

 discal band, Exp. 2'55" to 2-7" dryptUs. 



ht Forewing upperside male : with a costal and two 

 preapical white spots and another between 

 veins 2 and 3 with, mostly, a black dot on it : 

 of female : with an oblique white band of 

 three white spots. Exp. 2*5" to 2*6" nilgmeiisii. 



Genus— MELANITIS. 

 A. Forewing upperside : without, or with compai*- 

 atively small and narrow markings of ferrugi-
