Genus Phyciodes 



This species is one of many dimorphic species, the winter 

 form mar da, which emerges in spring, having the under side 

 brighter, and the light markings more conspicuous on that side 

 than in the summer form, which has been called morpbeus. Con- 

 cerning all of this, and the way in which cold affects the color of 

 butterflies, the reader will do well to consult the splendid pages 

 of Edwards and of Scudder. 



The pretty little Pearl Crescent ranges from southern Labrador 

 to Florida; in fact, all over North America north of Texas and 

 south of the region of Hudson Bay, except the Pacific coast of 

 California.

 to Ohio. 



(7) Phyciodes pratensis, Behr, Plate XVII, Fig. 37, $ ; Fig. 

 38, ?, under side (The Meadow Crescent-spot). 



Butterfly, $ . The butterfly resembles the preceding species 

 on the upper side, but the ground-color is much paler and the 

 black markings are not so heavy. The under side of the wings 

 is pale fulvous, spotted with yellow. 



? . The female has the black markings of the upper side

 ings on the under side are heavier than in the male sex. Ex- 

 panse, $, 1. 1 5 inch; ?, 1.40 inch.
