Agrotis balanitis, Grote, Plate 3, fig. 14, ?. 
? —Resembles repentis in general appearance, color, and size ; fore wings a 
little darker with a pale costal reflection ; ordinary lines blackish, perpendicular ; 
t. a. with the outer component line black, dentate; orbicular, moderate, a little 
pointed outwardly ; reniform incomplete, both spots concolorous, with narrow 
black annuli and pale gray inner edging. Median shade apparent on the 
median space below the nervure. T, p. line irregular, incompletely geminate, 
unevenly dentate, running inwardly below median nervure, and hence differ- 
ing from repentis, where it is even, nearly perpendicular, and does not run 
in inferiorly. Subterminal line much as in repentis, preceded by a dark 
shade. Terminal line broken into dots; fringes concolorous; hind wings 
pale smoky, without marks or border; fringes whitish, with a faint interior 
line. Beneath, pale, with discal dots, and a common transverse line broken 
into nervular marks on the hind wings. 
Lapanse,40 m. m. Habitat, Colorado Territory (coll. Theo. L. 
Mead, No. 34). 
This species offers a resemblance to Lycarum H.-S., fig. 122. 
Beneath, the abdomen, in A. balanitis, is laterally marked by a stig-

Agrotis atrifrons, Grote. 
9.—Antennae simple, scaled, ciliate, with scattered hairs, not bristled 
beneath ; ocelli; eyes naked; spurs short on middle and hind tibiae; fore 
tibiae spinose. Head with pale supra-caputal vestiture projected between 
the antennae; the clypeal scales are black and contrasting. Collar with a 
black line. Thorax above ashen. Fore wings ashen shaded with reddish 
brown; ornamentation simple. Transverse lines narrow, black, single, con- 
‘ tinued, t. p. line narrowly lunulate. Nervules marked terminally with dark 
scales. No trace of the ordinary spots. Median vein at base marked with 
blackish scales. The wing is shaded at base, above and below the m. nervure, 
with reddish ; again diffusely over the discal cell, and less obviously on the 
median space below the median nervure. Subterminal space dark, shaded 
with reddish brown, and bringing the subterminal line into relief by its 
contrast with the purely pale ashen terminal space. Hind wings white, 
smoky along the hind border, and the veins are also marked; fringes white, 
with a faint smoky interior line. Beneath whitish, costal region of hind wings 
irrorate, no discal dots on either surface; the primaries show a faint discal
