Apical portion of the fore wings reddish, and hind wings often shaded with 

 reddish beyond the outer line. The fringe varies with the color of the 

 wing, being speckled with brown or reddish, with a hair-line at the base

This protean form varies greatly in the color of the wings, owing to the 

 degree of speckling and distance of the point of the outer line from the 

 edge of the wing, the point being occasionally short and obtuse, and then 

 obsolete, as in var. amicaria H.-Sch. 



The distinctness of the submarginal black spots varies, being sometimes 

 entirely absent, and the outer edge of the bind wings is sometimes pale and 

 sometimes reddish-brown. 



In another individual (<?), from Natick, Mass., the angle of the outer 

 line is very obtuse and short, the point being nearly as far from the edge of 

 the wing as on the costa, the space beyond being reddish-brown, and with 

 scarcely any specks ; the wings are less falcate and angulated than usual. 

 Beneath, the outer edge of the wings has a faint violaceous hue. 



Fig. 40 represents the normal, most abundant form of H. nyssaria. 

 Fig. 39 represents var. amicaria H.-Sch. In this form, the outer third of 

 both pairs of wings is clear brick-red or red, with a decided purplish 

 tinge; the wings within are whitish, as in the normal nyssaria; the inner 

 line on the fore wings is broad. I have received it from Lawrence, Kans. 

 (Snow) and Alabama (Grote). Fig. 37 represents a second small variety, in 

 which the outer third of both wings is pale reddish; the lines are distinct, 

 reddish-brown, and the inner two-thirds of the wings is tinged with reddish. 



This form merges into another (closely resembling Walker's H.nepiasa- 

 ria from Nova Scotia), which nearly agrees with GueneVs description of 

 H. insinuaria, in which the entire surface of the wings is nearly uniformly 

 pale reddish-brown, with three submarginal dark spots, one subapical, one in
