I take the present occasion of thanking Mr. Theo. L. Mead, of 
New York, who has sent me a collection of Noctuidae for study ; 
in the present Paper I describe several new species he has taken in 
Jolorado. To Mr. J. A. Lintner, of the State Museum, I am under 
renewed obligations for the loan of material. 
Agrotis auxiliaris, Grote. 
4.—Abdomen flattened ; fore tibiae spinose; form elongate; habitus recalling 
the European yellow-winged species. Fore wings with distinct ornamentation. 
Cinereous along the costal region and subterminal space; blackish, shaded 
with carneous on the median and basal spaces. Basal half-line followed and 
preceded by determinate black shades; t. a. line distinctly geminate, outer 
line marked with black; a faint carneous shade over basal space inferiorly ; 
claviform wide, distinctly margined inferiorly, from its extremity to sub- 
terminal line a rigid carneous shade borders vein 2 superiorly; orbicular 
cinereous, decumbent, irregularly oval; reniform large, of the usual shape, 
touching the gray costal region above; with an attenuated inner darker 
annulus, followed by a faint carneous streak; t. p. line regular, even, formed 
by slight black lunulate marks; subterminal line irregular, marked within 
by two black cuneiform spots opposite the cell and others precede the line 
inferiorly ; terminal space dark, narrow; terminal line continuous, black, 
slightly interspaceally lunulate; fringes fuscous, with an internal pale line. 
Hind wings smoky, deepening in tint to external margin, without marks, sub- 
iridescent; fringes whitish, fuscous at base with a darker line. Beneath, a 
tuft of testaceous hair at base on median vein of primaries; both pair pale, 
subirrorate, with a rather distinct common darker shaded line and discal 
dots. Body ashen, collar lined, abdomen, with the anal and lateral hairs 
stained subearneously. 
Hapanse, 45 m.m. Habitat, Colorado Territory (coll. Theo. L. 
Mead, No. 57). 
Agrotis repentis, Grote and Robinson. 
The transverse posterior line is regular, formed by little black lunulate 
marks, which extend outwardly along the veins to the outer component line 
which is sometimes wanting, but occasionally appears as an even distinct 
shade. Median shade sometimes distinct and diffuse, again, as in the Colorado 
specimen, improminent. Fore tibiae spinose. 
Habitat, Atlantic District; Colorado Territory (coll. Theo. L. 
Mead, No. 33).
