42 L. de Niceville — List of the Butterflies of Galcutta. [No. 1, 



known, the rainy season seems to give birth to ocellated forms amongst 

 the SatyrincB. 



11. Mycalesis (Calysisme) blasius, Fabricius. 



Wot uncommon during the rains. The glandular patch of scales 

 which is placed on the underside of the forewing on the submedian 

 nervure in the middle of a nacreous patch in the male is hlach and 

 small. Mr. Rothney's list gives an additional species (1/. samha). 



12. Mycalesis (Calysisme) perseus, Fabricius. 



Very common during the cold and hot weather. The glandular 

 patch is hlach and small. 



13. Mycalesis (Calysisme) mineus, Linnaeus. 



Not uncommon during the rains. The glandular patch in this 

 species is ochreous and large. 



14. Mycalesis (Calysisme) indistans, Moore. 



Common during the cold and hot weather. The glandular patch 

 is ochreous and large. 



Summary of the four preceding species. Breeding will almost 

 undoubtedly prove that If. perseus is the dry season and M. hlasius the 

 wet season generation of one species, and that similarly M. indistans 

 is the dry season and M. tnineus the wet season generation of a second 

 sj^ecies, thus reducing the species of the subgenus Calysisme occurring in 

 Calcutta to two species, an ocellated form of both with an inner white 

 fascia (M. hlasius and M. mineus) occurring during tlie rains, and a 

 non-ocellated form with the white fascia obsolescent (M. perseus and 

 M. indistans) occurring during the dry season. 



15. Lethe europa, Fabricius. 



In the cold weather this species affects dry ditches. It occurs also 

 during the rains. 



16. Ypthima PHILOMELA, Johausscn. 

 Common amongst grass throughout the rains. 



17. Ypthima marshallii, Butler. 



Common everywhere during the cold and hot weather. This and 

 the preceding species are probably seasonal forms of one and the same 

 species. 



18. Ypthima huebneri, Kirby. 

 Common everywhere during the rains. 



19. Ypthima howra, Moore. 



Common everywhere during the cold and hot seasons. Similarly 

 this species and Y. huehneri are probably but two generations of one and 

 the same species, the strongly ocellated form in both cases occurring 

 during the wet season. 



20. Melanitis leda, Lianj^us.
