HOW TO KNOW THE BUTTERFLIES 



Fig. 29. — Synchlw olympi-a. 



This species being an Olympian, it has appar- 

 ently shared with the gods the privilege of incon- 

 sistency, for it is an orange-tip with the orange- 

 tips left off. However, the under sides of the 



hind wings are spangled 

 elaborately with brilliant 

 yellowish green, so it is 

 by no means a plain 

 butterfly. There is a 

 southern form called 

 rosa which has a beauti- 

 ful pink flush like the 

 upper clouds at sunrise, 

 spread over the under sides of the hind wings, 

 making a rosy background for the spangles. 



THE YELLOWS 



The yellows are easily recognized by their bright yellow 

 colors, although in some species whitish forms occur. They 

 abound almost everywhere in open fields, and are common 

 about wet places in roads. To this group belong the larger 

 number of our pierids. 



Our more common species, which are described below, can 

 be separated by the following table : 



A. Antennae with a distinct club, which is flattened, and is 

 rounded at the apex. 



I!. Front wings with a black bar along the inner margin.
