Luteous to fen urinous, fintly powdcrec]; median lines narrow, pale, even. 

 Basal line pale, often indefinite or wanting. T. a. line rigidly n]-)right, or 

 slightly oblique, rarely faintly sinuate. T. p. line variable; rarely rigidly up- 

 right, often arcuate or sinuate, usually about 

 parallel with outer margin. S. t. hue faint, 

 hardly paler, irregularly dentate; sometimes 

 preceded by a slightly darker shade. Orbicular 

 obsolete; reniform sometimes obsolete, more 

 usually marked as a narrow, slightly paler, rarely 

 white lunule, interiorly with a blackish dot. The median shade line is indis- 

 tinct, or entirely wanting. Secondaries blackish, with pale, more or less 

 reddish fringes. Head and thorax concolorous with primaries. Antennae 

 (^ $ with lateral bristles to each joint. Expands 1.4c — 1.4S inch. ; 35 — 37 mm. 



Had. — New York, Massachusetts, northward to Canada. 

 Distinguishable by the even, narrow, pale median lines and 

 indistinct irregularly angulate s. t. line.

 1S84, Tha.xter, Can. Ent. xvi, 2,2), life history. 

 Mouse-gray, with pale powderings, less distinct in median space; median 

 lines whitish. T. a. line remote from base, inwardly obliciue, even, rigid. 

 T. p. line rather narrower, even, bisinuate. S. t. line distinct, pale, irregu- 

 larly sinuate; through the middle of the s. t. space 

 is a rigidly oblique, rather broad, pale shade line. 

 Orbicular wanting, reniform narrowly and incom- 

 pletely outlined. The basal line is usually trace- 

 able, but olten absorbed in the pale powderings of 

 the basal space. The median lines are unusually 

 approximate. Secondaries a shade paler than primaries, but not powdery. 

 Beneath like secondaries above; powdery; a broad, diffuse, outer line on 

 both wings. Head and thorax concolorous with primaries; abdomen with 

 secondaries. The $ antennae are laterally bristled, in front clothed with 

 pure white scales for half their length. Exp. 1.20 — 1.32 inch.; 30—33 mm. 



Hab. — New York and northward. 



This species is very readily distinguished by the absence of me- 

 dian shade line, and the presence of a broad pale shade through s. t. 

 space. It is rather rare.
