in Figure 474. The lower surface of the wings is repre- 

 sented on Plate I, Fig. 7. A characteristic feature is the 

 presence of two submarginal eye-like spots on the hind 

 wing. 



The larva feeds on everlasting (Gnaphaliuiri) and allied 

 plants. The species occurs in Ontario and nearly the whole 

 of the United States. 



The Cosmopolitan Butterfly, Vanessa cardui (V. car'du-i). 

 The butterfly resembles the preceding very closely in 

 color and markings. There is, however, a smaller propor- 

 tion of orange markings ; and on the lower surface of the 

 hind wings there is a submarginal row of four or five eye- 

 like spots. 



The larva feeds upon Compositae, especially thistles. 

 This species is very remarkable for its wide distribution. 

 Mr. Scudder states that "with the exception of the arctic 



regions and South Ameri- 

 ca it is distributed over 

 the entire extent of every 

 continent." 



The American Tor- 

 toise-shell, Aglais milberti 

 (Ag'la-is mil-ber'ti). The 

 wings above are brownish
