(7) Argynnis callippe Boisduval. Plate XV, 9 , under side 

 (Callippe). 



Wings on the upper side obscured with dark brown on which 

 the pale buff spots, margined with black, stand out conspicu- 

 ously. On the under side the wings are pale buff, with a 

 greenish cast, the spots well silvered. Expanse 2.3 to 3 inches. 



Abundant in southern California, according to W. G- 

 Wright, preferring plains, and being confined mainly to the 

 little hot valleys which traverse them. According to the same 

 author the life of the insect as an imago is very brief, "the 

 shortest of any Argynnid that I know of, being only a few days 

 in length." 



Many of the western species do not have the spots on the 

 under side silvered, but are none the less beautiful for that. 

 One of these species, without silvery spots, the spots being 

 creamy white, without metallic lustre, is the beautiful insect 

 figured on Plate XVI, A. rhodope, the under side of the female 

 type of w T hich we show. There are nearly a dozen species of 

 Argynnis belonging to the same group with A. rhodope, but the 

 latter is the most beautiful of all of them.
