(4) Argynnis cybele (Fabricius), Plate XII, 9 , under side 

 (The Great Spangled Fritillary). 



The male is bright reddish-fulvous on the upper side of the 

 wings, with the characteristic dark markings of the genus; on 

 the under side the wings are heavily silvered. There always 

 is a pale yellowish submarginal band shown on the under side 

 of the hind wings which does not appear in the next species, 

 and by the presence or absence of which they may be discrim- 

 inated from each other. The caterpillars hibernate as soon as 

 hatched, and pass the winter in this state, feeding up and ma- 

 turing in the following spring when the violets begin to grow. 

 Expanse 3 to 4 inches. 



This species ranges from Maine to Nebraska and southward 

 to Georgia and Arkansas. It is our commonest species in the 

 Middle States.
