Family ERYCINIDAE. 

 Nymphidia, Fab. 



J¥yi«ii>IaBclia Jborealis, n. s. 



Upper surface, rich brownish ferruginous, covered and shaded 

 by dusky scales, which leave merely the narrow terminal space 

 (outside of the exterior metallic line) reddish ferruginous. Com- 

 mon, black, flexuous lines cross the wings basally ; these lines are 

 more or less continuous, but appear less macular than in N. pu- 

 mila, Bdv. and Lee. The outer and most prominent of these lines 

 is preceded by a broad, continued, black shade. Beyond, two exte- 

 rior lead-colored metallic lines, as in N". pumila, but the outer 

 line is straighter, and the inner appears more continuous, being less 

 exserted at the centre of the wing and less lunulate, indistinctly 

 margined by black scales ; these metallic lines are both narrower 

 than in 1ST. pumila. The interspacial dots are large and prominent. 



Under surface, bright orange yellow, of a rather deeper shade 

 on the primaries ; the black transverse lines are more interrupted. 

 Compared with N". pumila, the inner metallic line is less discon- 

 nected and angulated. The metallic spots on the costa which pre- 

 cede this inner line and which, in N. pumila, are very distinct, are 

 sub-obsolete in N. borealis. 



Upper surface of the body, blackish, clothed with dusky scales • 

 under surface and legs, fulvous yellow ; antennae, resembling those 

 of N. pumila, but longer, the club more prominent. 



Expanse, 1.00 to 1.10 inches. 



Habitat, New York State. 



With a general resemblance to N. pumila, Bdv. and Lee,
