98 Mr. W. C. Hewitson on 



Pieris nesha, Lucas (p. 341) . 

 Thyca agostina, Hewitson (p. 353) . 



P. nesha is tlie female of agostina ; and the latter name 

 has priority. My description and figure were published 

 in April, 1852 ; Lucas's description in July, 1852. 



Pieris ajal-a, Moore (p. 342) . 

 This does not differ from P. melite of Menetries. 



Pieris pigea, Boisduval (p. 342) . 



Mr. Wallace gives China as the habitat. I believe it 

 is an African species. My specimens, which I suppose 

 to be referable to this species, are from Natal. 



Pieris halora, Moore (p. 343) . 

 This does not diflFer from P. calUdice of Europe. 



Thyca lanassa, Boisduval (p. 361). 



This differs little from Pieris nahis, Lucas (p. 332) . 

 Both of them are probably mere varieties of P. rachel, 

 Boisduval (p. 331). At any rate, lanassa belongs to the 

 genus Pieris. 



Tachyris nerissa, Fabricius (p. 364) . 



Two of Cramer's figures of zehnira, E and F, which 

 Mr. Wallace quotes as females of nerissa, belong to another 

 species, and have a male similar to orhona, Boisduval, 

 from Madagascar. 



Tachyris paulina, Cramer (p. 369) . 



I wonder that Mr. Wallace should place neombo of Bois- 

 duval as a variety of paulina.. Neomho is constant in the 

 outline and breadth of the black margins. I have males, 

 resembling cga of Boisduval, which are decidedly the 

 other sex of neomho. I cannot discover what Mr. Wallace 

 considers the distinction between paulina and melania, 

 Boisd. (which he gives as the female of ega) , when he 

 unites Cramer's fig. 110 F, which has not any border to 

 the posterior wing on the underside, with Hiibner's fig. 

 of Icis, which has a broad border. I must also express 

 my want of belief that albina is the male of paulina ; it is 

 certainly not the male of neomho.
