178 THE BUTTERFLIES OF THE WEST COAST 



Cardui has a habit of occasionally migrating in endless numbers, 

 as written upon in another part of this book, under the head of 

 Migrations. 



231. Pyrameis Carye. 



Plate XXII ; Figure 231. Male, Southern California, 1895 ; 

 Author. 



This species resembles somewhat the preceding, on both the 

 upper and lower sides, but it can be recognized at a glance on 

 account of the tip of the fore wing being cut off square, and not 

 rounded. It is not anything like as universal as the preceding, 

 being found only on the West Coast of both Americas, and in the 

 United States not going east of Nevada, or perhaps Utah. 



The larval food-plant is Malva rotundifolia. This fact I have 

 proved many times. 



Hybrid. No figure. Alany years ago Mr. H. Edwards noted a 

 hybrid of Carye and Atalanta. It seems scarcely worth mention. 



Muelleri. No figure. A variety known as Muelleri is of occa- 

 sional occurrence ; in this variety all wings are blurred or flushed 

 with fulvous, at the expense of the black markings, and the white 

 spots are elongated and obsolescent. 



234. Junonia Ccenia. 



Pl.\te XXIII ; Figure 234, Southern California. June, 

 1880; Author. 



The figure is that of a male. Ccenia is a plains and valley butter- 

 flv, where they are very abundant from spring to fall ; but they 

 do not frequent the hills and mountains. Ccenia is somewhat com- 

 mon over most of the temperate States of the Union, also in Can- 

 ada, and Mexico, to some extent. 



The sexes look much alike : the determination is by the lappets, 

 and by the size and shape of the body. 



The preliminary stages are well known : the larvae feed on 

 antirrhinum, plantago, and some other plants ; probably on the 

 Coast the antirrhinums afford most of the food for the larvse. 



235. Junonia Genoveva. Not elsewhere illustrated in 



America. 

 Pl.\te XXIII ; Figure 235, Mazatlan. Mexico, Jan. 10, 

 1888: Author. 

 Genoveva is mostly a Mexican butterfly, but comes north far 

 enough to get within .Arizona territory along the southern boun-
