somewhat attenuated at extremities, usually with more or less 

 close short hairs. Pupa with the head more or less pointed, 

 attached by the tail and a central belt of silk. 



Colias and Gonepteryx are nearly correlated, and so are 

 Pieris and Aporia; the other two genera have no immediate 

 connection either with these or with each other.

 hemisphere and in Africa. The 

 imago has a very bold and 

 strong flight. When at rest, the 

 under side of the hindwings 

 closely resembles a faded clover- 

 leaf with a central fungus-spot.
