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

 distinct, black. T. a. line iiprit;iit, somewhat irregular, varying in shade from 

 brrtwn to l)lack. T. p. line Ijlack, 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 thora.x concolorous with primaries. Secondaries blackish with 

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

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



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

 shire, Maine, Canada. 



A very distinct species, evidently bel(jngin^' to the narrow winged 

 series, and yet with considerable likeness in niaculation 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.
