Note (Plate XXVIII) the absence of a 

 broad yellowish submarginal band on under- 

 side of hind wing, but usually there is a 

 narrow one and it is often difficult to tell aphrodite from 

 cybele; they may hybridize. The life history, immature 

 stages, and range, much like cybele. 



The Mountain Silver-spot is much like 

 the preceding species but is smaller, and 

 darker at the base of the wings both above 

 and below. On the upper side there usually is present 

 a narrow black border to all the wings and on the hind 

 pair the black spots in the middle are connected to form a 

 very narrow irregular band. Below, the submarginal 

 band of yellow on the hind wings is paler. The males have 

 a decided odor of sandal-wood. In early stages and life 

 history it is similar to aphrodite but it is more confined 

 to mountainous regions especially in the Southeast. 



There are many other species of this genus in the West, 

 all rather difficult to identify correctly; and Brenthis (q. v.) 

 is often united with it. A. diana of the Southeast is 

 interesting because the male has the outer third of the 

 upper side of the wings orange while the female is black with 

 blue spots. As a rule, larvae of this genus have the front 

 spines the longest ; they feed chiefly at night. The chrysa- 

 lids have a forked head. 



Although the upper side of the Silver-bor- 

 Brenthis dered pritillary is tawny with black mark- 



ings and resembles B. bellona, the species 

 are easily distinguished by the fact that myrina is rich in 

 silver spots on the under side of the wings (Plate XXIX). 

 Its larvae feed on violets, and after hibernating get to be 

 about an inch long ; they are dark olive brown with lighter 

 markings and are covered with fleshy spines. Chrysalis: 

 dark with darker spots and somewhat curved forward. 



See Plate XXIX and the description of 

 myrina. The Meadow Fritillary has no 

 silver underneath. Its life-history is much 

 like -that of myrina. 



The chrysalids of Brenthis have two rows of conical
