AMERICAN LEPIDOPTERA. 177 



wardly, and somewhat sinuously outwardly obliquely, until over third 

 median nervule, whence it is bent inwardly obliquely, being once in- 

 wardly dentated on the submedian fold to internal margin. Below 

 third median nervule it is limited inwardly by a dark coincident line, 

 which is apt here to become confounded with the median shade-line, 

 the latter in reality running very faintly and approximately inside of 

 it. The t. p. line is margined outwardly by a very distinct, bright and 

 deep brown, oblique streak, which becomes broader on submedian fild 

 where it is inwardly dentate, coincident with the line itself and the in- 

 ner line. There is thus a certain conformity suggested, between the 

 appearance of the two median lines below median nervule, which is 

 strengthened by their juxtaposition and the constriction of the median 

 space at this point. Without the t. p. line the wing is terminally dark 

 brown, and there is a subteriuinal zig-zag streak or series of streaks of 

 a deep brown color, and followed outwardly by pale scales, which is 

 more or less obsolete, and of which the continued deep brown streak, 

 margining the t. p. line outwardly inferiorly, is perhaps the terminal 

 inflection. Within and over internal angle the wing is pale, and shows 

 a black spot or shade about third median nervule on the margin. The 

 ashen fringes are here clouded and lined with blackish. Secondaries, 

 smoky grey, without markings, a little paler at base. Under surface, 

 smoky grey, the secondaries whitish, without markings on either 

 pair.

The darker shaded upper surface of the labial palpi, the general 

 light brown color and the grey median space of the primaries, together 

 with the more lengthily pectinated antennae — are characters which se- 

 parate this species from Dasylophia anguina, Puck., {Phahiena angui- 

 na, Smith; 9 L)n/7noiiia cucuUifera, H-S.), and which are indicated 

 in the original description. The typical specimen is from New Hamp- 

 shire, and is preserved in Dr. Harris' Collection, now in possession of 

 the Boston Society of Natural History.
