spots distinct; terminal space darker, more heavily powdered. Basal line 

 distinct, black. T. a. line npright, somewhat irregular, varying in shade from 

 brown to black. T. p. line black, parallel with outer margin, with black 



points on veins making it crenate. A 

 more or less broken brown shade in s. t. 

 space serves to indicate the concolor- 

 ous s. t. line. Through the median 

 space is a dark brown shade, outwardly 

 angulate, the angle touching the black 

 filling of inferior portion of reniform; 

 the latter is large, not defined, usually 

 of a paler shade of ground color, but 

 often white; always, however, the inferior portion is black filled. The or- 

 bicular is small, round, concolorous, neatly brown ringed. The claviform is 

 small, pointed, inconspicuous, but evident in all specimens I have seen. 

 Head and thorax concolorous with primaries. Secondaries blackish with 

 reddish fringes. Beneath reddish powdery, with a variably distinct outer line 

 and discal lunule. Expands 1.20 — 1.40 inch.; 30 — 35 mm. 



Hab. — Dist. Columbia, New York, Massachusetts, New Hamp- 

 -shire, Maine, Canada. 



A very distinct species, evidently belonging to the narrow winged 

 series, and yet with considerable likeness in maculation and habitus 

 to the wider winged forms. The black spot in inferior portion of 

 reniform, the evident claviform, the darker terminal space and crenu- 

 lated t. p. line are distinctive.

Reddish luteous, powdery, maculation often indistinct, subobsolete. 

 Basal line rarely traceable. T. a. line often indistinct, or even entirely want- 

 ing; when present, rigidly upright, pale or dusky, preceded by a narrow pale 



shade. T. p. line well removed toward, 

 and parallel with the outer margin; crenu- 

 late, dusky or blackish; often indistinct. 

 .S. t. line very faint, concolorous, barely 

 traceable,, sometimes more relieved by 

 blackish powderings at either side; median 

 shade variably distinct, angulate; the angle touching the reniform inferiorly. 

 Orbicular wanting; reniform a narrow, blackish lunule, usually with a larger 

 ovate white spot in the middle and small white dots at the tips. Secondaries 

 smoky to blackish, with pale fringes, variably shaded with reddish. Beneath 

 with a dusky common line, variably complete; and a discal lunule. Antennce
