stripe running through the spiracles below which the color is 

 decidedly lighter than above. Pupation takes place in the 

 ground. The pupa is J inch in length and of a dark mahogany 

 brown. The pupal period varies from two to four weeks. 



The moths are on the wing from late May to October and 

 apparently belong to two overlapping broods. The moth 

 has an expanse of 1| to 2 inches (Fig. 154). The front wings 

 are rich purplish to reddish brown. The kidney-shaped spot 

 is usually tinged with reddish. From this spot there extends 

 towards the base of the 

 wing a black bar deeply 

 incised by a triangular 

 light area which often 

 extends to the front margin 

 of the wing. The hind 

 wings are smoky, darker 

 along the outer margin. 



The moth deposits her 

 eggs singly, in rows, or in 

 compact clusters of 200 or 

 more on leaves. The egg is hemispherical in shape, strongly 

 ribbed, almost transparent and is about 2V inch in diameter. 

 There are probably two generations annually.
