Genus Phyciodes 
This species is one of many dimorphic species, the wintei 
form marcia, 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 morpheus. 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.

This species ranges from New York to Virginia, and westward 
to Ohio. 
(7) Phyciodes pratensis, Behr, Plate XVII, Fig. 37, <3 ; Fig. 
38, ?, under side (The Meadow-Crescent-spot). 
Butterfly, <3.—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 
heavier than the male, and all the spots pale yellow'. The mark¬ 
ings on the under side are heavier than in the male sex. Ex¬ 
panse, <3, 1.15 inch; ?, 1.40 inch. 
Early Stages. —Unknown. 
The range of this species is the Pacific coast from Oregon to

(8) Phyciodes orseis, Edwards, Plate XVII, Fig. 31, <3 
(Orseis). 
Butterfly , <3 .—The dark markings on the upper side are much 
heavier than in either of the two preceding species, and the ful¬
