The genus I have now placed it in belongs to the CoUada, and 

 appears to connect that family with the Pierida : their distinc- 

 tions are obviously marked and very constant in all the species I 

 have yet seen, and which are tropical : of these, seven I disco- 

 vered in Brazil; three or four more are natives of the southern 

 extremity of North America ; and Dr.Horsfeild has four or five 

 from Java. I know of none from Africa. Their size in gene- 

 ral is very small. 



I think this species is the Pieris Elvina of Godart; although 

 the insect he mentions as the female is in reality that of his 

 Pieris 'Neda. The true female I have never seen ; I suspect it 

 will want the gibbous curve on the hinder wings of the male, 

 which sex is, indeed, not common, and is generally much smaller, 

 and sometimes half the size only, of the figure. 



Papilio Nicippe of Cramer (tab. 210. fig. C D.) strictly be- 

 longs to this genus, though placed in that of Colias by Godart, 

 as well as his Pieris Agave, Hecabe, and doubtless many others, 

 not novvf before me.
