LEUCOPHASIA. 39 



small discoiilnl cells. As yet only two species of the genus are known, ami some very good Lepidopterists still 

 consider them only varieties of one species. Both are confined to Europe ; one is not uncommon in Britain. 



In general they frequent open places in woods, flying not very rapidly, with an undulating unsteady motion. Our 

 own species occurs both in the spring and autumn. Those of the autumnal brood almost entirely wanting the black 

 at the apex have been formed into a species by Hiibner, under the name of P. Erysimi. 



The Larva feeds on various Papilionaceous plants, especially Vicia Cracca and Lotus coruiculatus ; resembling in 

 this respect those of the genera Terias, Colias, and Callidryas, more than those of Pieris and Anthocharis. It is 

 green, with a lateral yellow stripe. The Pupa is elongate, very pointed at each extremity.
