THE NYMPHS 



Phyciodes. On the under surface the wings are fulvous, with 

 the veins and transverse lines and bars black, and with pale 

 yellow and silvery white spots. On the hind wings the 

 median, transverse, white band is traversed by two black 

 lines near the edges, so as to form three nearly complete 

 bands. Expanse one and three-fourths inches. 



Caterpillar. — Length nearly one inch; body orange in 

 color ringed with black stripes, with a black line down the 

 back, and ornamented with rows of black spines. 



Food-plants. — Asters. 



When flying, this hutterfly so much resembles 

 the silver crescent that it is likely to be mistaken 

 for it ; however, the lower sides of the wings 

 are much darker. The caterpillars have similar 

 habits to those of the silver crescent. It is a 

 New England species, seldom being found south 

 of the 42d degree of latitude. 



The Silver Crescent 

 Charidryas nycteis (Cha-rid'ry-as nyc-te'is) 



Plate XXII, Fig. 6, 7 



The silver crescent is most easily distinguished by the mark- 

 ings of the lower surface of the wings, the outer margin of 

 which has a distinct, narrow, yellow terminal line of nearly 

 uniform width, bordered within and without with brown. 

 Just within this line there is a series of silver-white lunules ; 

 these lunules are very small or wanting in cells M, and M 2 of 

 each wing. There is a transverse band of silver-white or
