100 THE BUTTERFLIES OF THE WEST COAST 



plants, and do not lay their eggs on any cultivated plants, unless 

 compelled to do so. I have raised Raps larv'se to imago from eggs 

 laid on common garden Nasturtium, the larvae being fed solely on 

 the leaves of that plant. 



49. Pieris Nov-Angliae. 

 No figure. 



This is a minor variation of Rapae, named for New England, 

 where it was first noted, and it is set down in the lists as occurring 

 all over the United States wherever Rapse may fly. But there is 

 no account of this form ever having been seen on the West Coast. 

 The peculiarity of this form is that the wings are all yellowed on 

 both sides, whereas the typical Rapae is yellow only on the under 

 side of hind wings, and apices of fore wings. 



Manni. This name stands for a pale yellow form of Rapae, and 

 presumably there is but little diflference between this and the pre- 

 ceding, but, as stated, these yellow forms have not yet been seen 

 on the West Coast. 



50. Pieris Immaculata. 



No figure. 

 This is another variation of Rapse, not yet seen on the Pacific 

 Coast ; the name indicates that it is not spotted with black. These 

 names are mentioned as it is possible that such forms may at any 

 time be found here. 



51. Pieris Marginalis.

 At about the same time that Rapae was introduced into the At- 

 lantic States from Europe, or, perhaps, a few years earlier, a simi- 

 lar species was found on one of the islands of Puget Sound, and 

 also near Crescent City in northwestern California ; these western 

 Rapae were given the names Marginalis, Yreka, Resedae, by dif- 

 ferent authors, but these names are now generally ignored. I will, 

 however, illustrate one example, and that one will be sufficient to 

 cover all of the names, I believe. 



Genus NATHALIS.
