 broad, blackish, sometimes obsolete. T. a. line outwardly oblique, 

 with a long, inward tooth on vein 1. T. p. line geminate, crennlate, 

 not qnite parallel with outer margin ; more upright. S. t. line inter- 

 rupted, marked by pale scales, preceded by black sagittate dashes, one

 median shade line. Orbicular rarely defined. Reniform obsoletely 

 marked by a few dirty white scales. Secondaries smoky fuscous. Be- 

 neath powdery, with variably distinct outer line and discal spot. 

 Head and thorax concolorous. The harpes of the male are broader

An obscure, sordid species, defined by the sagittate black marks 

 preceding s. t. line. The thoracic vestiture is rather loose and long, 

 the abdomen of male long and slender. The primaries have the costal 

 margin somewhat concave at middle, the apices rectangular, outer 

 margin straight to below middle, then very obliquely rouuded to hind 

 margin.

Proc. U. S. Nat. Mas., 1887, X, 478. 



Red brown, powdery ; median lines distinct, accompanied by broad, 

 luteous shades. T. a. line waved, with a wide outward bend at middle. 

 T. p. line crennlate, nearly parallel with outer margin. S. t. line broad, 

 diffuse, pale, preceded by a dusky shade. An interrupted terminal 

 liue ; fringes pale, dotted at base. A more or less indistinct shade line 

 through outer portion of median space. Orbicular small, indefinite, 

 luteous. Reniform narrow, upright, indefinite, luteous. Secondaries 

 blackish, paler in some specimens. Beneath, powdery, with a broad, 

 diffuse outer shade, black. A distinct discal spot on secondaries. The 

 harpes of male gradually narrow to an obtuse tip, inwardly fringed 

 with hair. The clasper is concave, somewhat curved, the tip corneous, 

 acute. Expands 1.10 to 1.20 inches (27 to 30 mm ). 



Habitat.— State of Washington. 



Readily recognizable by the pale shades accompanying the trans- 

 verse lines, as well as the coarsely powdered primaries. The broad, 

 diffuse outer line of under side seems also characteristic. The types 

 are with Messrs. Graef (female) and Hy. Edwards (male).
