Geous— YPTHIMA. 



A. Hindwing underside : with two subapical ocelli ; 



the ocelli arranged in pairs in echelon. Exp. 

 l-25"-l-28" pldlomela. 



B. Hindwing underside : with one subapical ocellus. 

 a. Hindwing underside : with two posterior ocelli, 



the lower one geminate (with 2 pupils). Exp. 



l-4"-l-7" asterope. 



h. Hindwing underside : with three posterior ocelli, 

 the tornal one geminate. 

 a^. Hindwing upperside : brown. Exp. l*6"-r7'... huebneri. 

 b^. Hindwing upperside : partly pure white. Exp. 



1-7" ceylonica. 



The ocelli of the underskle of hindwing in these last two are all in 

 :a line, not ^chelonned in pairs as in phUomela. It should be noted 

 that the upperside of hindwing in the last species must be pure white ; 

 greyish-white or grey will not do : such is often the colour of the wing- 

 in the dry-weather i'ovm of huebneri. All these butterflies have a wet 

 ^nd dry-season form, the former with all ocelli well developed and the 

 ground-colour finely striated on the underside and rather dark, the 

 latter with the ocelli reduced sometimes there to mere black spots and 

 the whole of the ground-colour on which they are placed suffused 

 with grey-white. This suffusion often invades the upperside in 

 huebneri. The larvas of philomela and huebneri have the head rounded 

 without horns but have the usual tnil-points : thoy are green and feed 



•on grasses. 



Genus— ORSOTRICENA. 

 A. Underside : with a transverse narrow white band 

 hardly 2mm. in breadth. Exp. l-75"-2" (^Vide
