HOW TO KNOW THE BUTTERFLIES 



The Silver-bordered Fritillary 



Brcnthis myrina (Bren'this my-ri'na) 



Plate XXII, Fig. i, 3 



This species differs from the meadow fritillary in having on 

 the under side of the hind wings two transverse series of 

 silver spots, one marginal and one submarginal ; there are 

 also several larger silver spots on the base of the wing. 



Caterpillar. — Length three-fourths inch. In color a 

 mottled green, brown and purple, with spines like the cater- 

 pillars of Argynnis except that in this species the pair of 

 spines on top the first thoracic segment are several times as 

 long as the others. 



Food-plant. — Violets. 



When in our childish ignorance we regarded 

 a small butterfly as not yet fully grown, we often 

 found on thistle blossoms in the pasture certain 

 small butterflies that carried " money " under 

 their wings and we thought them too young to 

 be trusted with so much silver. These small 

 Croesuses were the silver-bordered fritillaries. 



The silver-bordered fritillary is a pretty little 

 creature decorated in rather conventional squares, 

 dot c and scallops of black and orange that sug- 

 gest canvas embroidery. On the lower side of 

 the wings the silver spots are set in with brown 

 and yellow squares and lines; the border of "half 

 coins " on the hind wings is especially prominent
