BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 



butterfly is readily known by its sulphur-yellow wings with black 

 borders. A pale form of the female occurs in which the wings 

 are whitish or yellowish- white ; sometimes a male form occurs which 

 is thickly covered with black scales, so as to obscure the yellow 

 ground color. The caterpillar lives on clover and allied plants. 



12. Orange Sulphur Butterfly (Colias eurytheme). 



Very rare in this vicinity, but common in the Southern and 

 Western States. It differs from Colias philodice in having the wings 

 orange instead of yellow. The caterpillar lives on clover. 



13. Orange-Tip (Euchloe gemitia). 



This pretty species is local, and appears to be restricted to certain 

 localities. It is on the wing early in May, and flies until about the 

 middle of that month. The butterfly is white with the tips of the 

 fore wings orange in the male; the under side of the hind wings 

 is marbled with green. The caterpillar is dark yellowish-green, 

 glossy, with a yellow stripe along the back and a broader white one 

 on each side. It feeds on rock cress (Arabis). 



14. Orange Butterfly (Eurema nicippi). 



About 1880 this beautiful species appeared in considerable num- 

 bers in Central Park, New York City, and other places around New 

 York, but since then only a few specimens have been taken. The 

 butterfly is found from the Atlantic to the Pacific, and in most of 

 the States south of Lat. 40 in Mexico and in Central America. In 

 the South it is very abundunt. The caterpillar lives on senna (Cassia).
