252 THE BUTTERFLIES OF THE WEST COAST 



461. Nisoniades Perseus. 



Plate XXXII; Figure 461, Male, San Bernardino Mts., 

 July, 1899; Author. 

 This butterfly is found flying on the plains and also on the 

 mountains of moderate height ; one of the most common species, 

 and a voracious feeder on flowers, seemingly always hungry, and 

 never satisfied. It is common all over the United States west of 

 the Rocky Mountains. 



The food-plant is said to be willow, but there must be some 

 other plant as well. 



462. Nisoniades Juvenalis. 



Plate XXXII ; Figure 462, Female, Lake County, Cal., 

 June 20, 1894; Author. 

 This species is common at the East, but is more rare on the West 

 Coast, being occasionally met with in the southern parts, but not 

 present in the more northern portion of the Coast States. 

 The food-plants are the leguminous or pod-bearing plants. 



463. Nisoniades Propertius. Not elsewhere illustrated. 

 Plate XXXII ; Figure 463, Male, San Bernardino Valley, 



1903 ; Author. 

 This is sometimes considered to be the Western form of the 

 Eastern Juvenalis ; it is one of the most uninteresting species, and 

 is usually not taken when it is met with, and so the localities are 

 not well filled out ; at present it is credited only to California and 

 Vancouver Island, but doubtless inhabits Oregon and Washington 

 as well. 



464. Nisoniades Clitus. 



Plate XXXII ; Figure 464, Female, Southern California, 

 June, 1891 ; Author. 

 Clitus is a strong-flying and active butterfly, and is usually 

 taken while feeding on flowers, as it is difficult to catch while in 

 flight. It is a southern species, and is not found north of the 

 Tehachapi Mountains. The chief feature of this species is the 

 wide white fringe to hind wings.
