1 c?. — Of medium size; antennae broadly pectinated; hind wings rounded, 

 fuller than in II. unitaria and more deeply serrated, the entire edge being so. 

 Body and wings pale ash; front with a round dark spot; palpi with the third 

 joint black. Hind edge of prothorax and hinder edge of the basal segments 

 of the abdomen with a black band. Fore wings reddish-ash, with a broad, 

 curved, basal, blackish band ; outer line slightly oblique ; straight on the inner 

 edge, curved inward in the middle of the wing, thence going straight to the 

 costa ; this portion of the line is represented by three or four venular dots, 

 the costal one being the largest, while the posterior two-thirds of the line is 

 bordered externally by two diffuse, parallel, broad lines, the whole making a 

 broad band. Costal edge speckled with dark ash. Outer edge scalloped, with 

 a black point between each scallop. Hind wings concolorous with the fore 

 wings; two parallel slightly-waved lines; beyond the middle of the wing a 

 very distinct, nearly straight, blackish line, with a supplementary brown shade 

 beyond. A submarginal broad shade. A black line follows the scallops. 

 Fringe pale ash. Beneath uniformly pale ; costa with transverse dark strigae ; 

 the outer band forms a smoky shade beneath, and on the hind wings a smoky 

 line. Legs ash-colored ; two anterior pairs of tibiae and tarsi broadly banded 

 with blackish. 



Length of body, 0.60 ; fore wing, 0.73 ; expanse of wings, 1.50 inches.

4 J and 1 9. — Body and wings whitish-ash; head brown in front, a 

 whitish line just in front of the antennae; vertex whitish. Thorax whitish, 

 witli a transverse brown line on the front edge of the prothorax. Fore wings

 lops very shallow; inner line curved outward below the costa, parallel with
