THE BUTTERFLIES OF 3WSS00RIE. 383 



larger and a shade lighter in colour. The opposite sexes in this 

 species are coloured and marked almost exactly alike — an unusual 

 feature in the genus. 



167. Arrhopala ganesa, Moore. 



The commonest species of the genus found in Mussoorie, flying in 

 shady ravines near running water in May and June. The larva, as 

 in the case of the two species which precede, feeds on the young leaves 

 of Quercus incana, Roxb., Natural Order Cupuliferce, is of a very beauti- 

 ful pinkish-white colour, covered with very fine and soft white hairs, 

 extending all round beyond the body. The larvse of A. rama, Kollar, 

 A. dodoncea, Moore, and A. ganesa, when nearly full-grown, remain in 

 a shelter made by fastening the edges of a leaf together. The ants 

 which attends the larva of this species are much larger than those 

 which pervade the larvse of the other two species. All these species 

 have a honey-gland on the eleventh segment. 



168. Curetis angulata, Moore. 



Very rare in the valleys about Mussoorie in August and September ; 

 occurs in Dehra Dun in September. 



169. Curetis dentata, Moore. 



Found in Mussoorie and Dehra Dun ( from whence it was 

 originally described) with the species which precedes and follows. 

 170. Curetis bulis, Doubleday and Hewitson. 



Found in the low valleys about Mussoorie from June to September; 

 not rare in the Dun in April, July, August and September. It is 

 unfortunate that no fresh evidence is forthcoming of the distinctness 

 or otherwise of the various species of this genus which have been 

 described. 



171» Thecla sassanides, Kollar. 



Brought in by native collectors in July and August from the Nila 

 Valley, close to the Ganges, at an elevation of about 8,000 feet. 

 172. Zephyrus ataxus, Doubleday and Hewitson. 



Excessively rare in Mussoorie and in a valley near Nag Tiba, and 

 flies from May to July. Z. ataxus is the male, and Z. Jcatura t Hewit- 

 son, the female of one and the same species.
