AMERICAN LEPIDOPTERA. 17 



the scales may be gray on the thoracic crest. Primaries with all the markings 

 traceable, but none of them contrasting. The basal half line is brown, visible 

 on the costa in most specimens and sometimes below the cell. T. a. line imper- 

 fect, single, brown, almost upright, outeurved between the veins. T. p. line 

 geminate, the inner line almost even or a little crenulated, slightly outeurved 

 over the cell and a very little incurved below. The outer line is dotted, the dots 

 connected by a dusky shading. The dots are on the veins and are black, followed 

 by white in most cases. The white dots may be absent or they may be prominent 

 and followed as well as preceded by a black dot. The median shade is broad, 

 diffuse, well marked and forms an angle, just below the reniform, which is infe- 

 riorly darkened by an extension of this shade. S. t. line pale, irregular, marked 

 by the darker terminal space and by a dusky preceding shade. Near the costa 

 it is defined by the paler apex and dusky s. t. space. There is a pale terminal 

 line which is emphasized by black dots on the veins. All the veins are more or 

 less flecked with white and black scales, particularly in the s. t. space and beyond 

 it. The ordinary spots are moderate in size, concolorous or slightly paler, out- 

 lined by white and black scales. The orbicular is oval, oblique, the reniform 

 upright, constricted in the middle and considerably dilated inferiorly. It is also 

 blackish shaded in its lower portion. The fringes are distinctly scalloped, and 

 the angle near the middle of the wing is much better marked than usual. Sec- 

 ondaries a smoky luteous, the fringes a little paler, with a darker line at their 

 base. Beneath pale yellowish, primaries tending to become smoky, the second- 

 aries tending to yellow. Both wings are powdered toward the edges, and both 

 have a more or less well-marked outer dusky line and may have a discal Iunule. 

 Expanse 1.25 1.50 in. ; 31-37 mm. 



Huh. — Canada to Virginia, west to the Mississippi River, Mis- 

 souri, Iowa. Date of flight June, July and August. 



This is not an uncommon species, and occurs throughout the 

 whole Northern, Eastern and Central United States. The speci- 

 mens run even, and the species is recognizable by the fact that it is 

 the only one in which the ordinary spots are outlined by white 

 scales. The ring is a very narrow one, but is quite evident. The 

 antennae of the male are entirely simple. The harpes of the S are 

 long, very broad at the base, abruptly bent toward the tip, and at 

 the point of bending is a large curved, corneous clasper, which ex- 

 tends to the tip and almost across the harpes at the base. Near the 

 middle of each harpe is a slender, pointed process, which may be 

 considered an accessory clasper. 



Hydroecia interoceaiiica n. sp., pi. 1. fig. 4, %, genitalia. 



Ground color a very dark smoky brown, the ordinary markings almost black- 

 ish. In general the species resembles nictitans, or, more correctly, atlantica ; hut 

 it is smaller, much darker in general color and, so far as the specimens in hand 

 show, the reniform is uniformly white marked. The orbicular in all the speci- 

 mens before me is round, considerably paler and more yellowish than the ground 

 color, but without any trace of while markings. Expanse 1.10-1.25 in.; 28 31 mm. 



Hub — Winnipeg, Manitoba.
