50 L. de Nicoville — List of the Butterflies of Calcutta. [No. 1, 



underside of a pale violet colour, and tlie subjacent portion of the wing 

 membrane slightly depressed. On holding a male insect up to the light 

 this secondary sexual character can be at once detected. 



100. Terias simulata, Moore. 



This species and the next have the male mark above referred to. 



101. Terias ptjrreea, Moore. 



Taken in the cold weather, not common. 



102. Terias lz^ta, Boisduval. 



There is one specimen of this species in the Indian Museum, Calcutta. 

 T. laeta and allied species have in the male an oval patch of ochreous 

 scales on the underside of the forewing near the base below the median 

 nervure. 



103. Terias drona, Horsfield. 



104. Terias rubella, Wallace. 

 Taken in December. 



105. Catopsilia catilla, Cramer. 



106. Catopsilia crocale, Cramer. 

 Feeds on Cassia fistula, 



107. Catopsilia gnoma, Fabricius. 



108. Catopsilia pyranthe, Linnaeus. 

 Feeds on Cassia fistula. 



*109. Catopsilia ilea, Fabricius. 



110. IxiAS GANDUCA, Moore. 



Occurs in February, and again during the rains. J. latifasciafa, 

 Butler, is given in Mr. Rothney's list, but I. ganduca is probably meant. 



111. IxiAS MARIANNE, Cramer. 

 Very rare. 



112. HuPHiNA PHRTNE, Fabricius. 



Common, feeds on Cai^paris horrida. It appears in Mr. Rothney's 

 list under its synonymic name H. evagete, Cramer (teste Moore, P. 

 Z. S. 1882, p. 255.) 



113. HuPHiNA HIRA, Moore. 



I think that this is only a seasonal (winter) form of the precedino- 

 species, which is a very variable one. 



114. HuPHiNA ZEUXIPPE, Cramer. 



This also appears to me to be a seasonal or varietal form of H. 

 phryne. 



*11^. Catophaga PAULINA, Cramer. 



116. Catophaga darada, Felder. 



I have taken a single male specimen only in August. 



117. Appias zelmira, Cramer. 



I have seen a single male specimen taken in Calcutta.
