The extensive genus above described, with Colias and Terias which precede, and Pieris which follows, 

 as well as the genera Gonepteryx of Leach, and Leucophasia of Stephens, were all originally included in a 

 single subdivision of the genus Papilio of Linnaeus. The paleness of tint by which the individuals of this 

 group are generally characterized, suggested the designation of Z)ana2 Ciznc?zc??, to which the name of Whites 

 has been accommodated in the English nomenclature. From this group, which at the time of its limitation 

 was tolerably natural, the genus Colias was separated as early as the year 1776, by the acute authors of the 

 Wiener Verzeichnis. They were led to this judicious separation by their extensive researches regarding the 



metamorphosis
