15 <? and 15 9. — Wings acutely angled in the middle <>l the outer edge, 

 and fore wings very falcate; hind wings extending farther than usual behind 

 the tip of the abdomen. Fawn-color, sometimes frosted over and varying to 

 oehreous; body concolorous with the wings, which are more or less striated. 

 Head with the front chocolate-brown; vertex white. Fore wings with the 

 inner line usually present, curved, consisting of two large scallops meeting on 

 the median vein and pointing inward, the upper scallop touching the discal 

 dot, or the line is straight below the dot and parallel with the outer 

 line; the line is sometimes either absent, or represented by a few scattered 

 patches, and when well developed is dark fawn-brown, with or without a 

 frosty edging on the inside. Outer line straight, more or less distinctly 

 angled near the apex, and bending at right angles on the costa ; sometimes 

 the angle is much rounded, brown or black-brown, simple, or edged exter- 

 nally with gray. From the angle extends a more or less distinct slightly- 

 curved series of irregular diffuse dark spots to the inner angle ; this is usually 

 represented by a faint shade. Discal dots alike in both wings, Small, con- 

 sisting of erect black scales. Hind wings with the single line in the middle 

 of the wing, straight, with the outer series of diffuse spots as on the tine 

 wings. Fringe a little deeper in hue than the wings, varying in hue between 

 an oehreous or fawn color. Beneath, a little paler than above; line not pres- 

 ent, or very faint, distinctly dusted with transverse strigcie. Legs strigated. 



Length of body, J, 0.72-0.S5, 9, 0.65; of fore wing, <? , 0.90-1.00, 

 9, 0.95-1.00; expanse of wings, 2.00-2.10 inches.

This is a very variable species, and in the above description we have 

 noted the extremes. It may be distinguished l»y the very falcate wings, the 

 obtusely-angled outer line on the fore wings, the suhmarginal shade or row 

 of spots on both wings. The oehreous variety, which I take to be goniata, 

 would easily be considered a separate species from trcmsversata Guen. ; but 

 they are intermediate forms ; so one of the Georgia males is dark, uniformly 

 lawn-colored, with the margin of the wings beyond the outer line darker, and 

 would be at first thought specifically distinct.
