but the most obvious difference and the one that will enable this species 
to be readily recognized is in the black filled ordinary spots. In this 
character the species is unique. The insect gives the impression, some¬ 
how, of a dirty creature. 
The male parts are very simple, consisting of a single upright corne¬ 
ous process on a broad triangular harpe. 
Setagrotis elata, sp. nov. 
Ground color ash gray, varying in general shade from a yellowish to a bluish 
tinge. Head and thorax without markings of any kind. Primaries with all the 
markings obscured and very feebly traceable. The median lines are always visible as 
geminate black costal spots, but beyond that they are only vaguely indicated. In a 
general way and so far as can be indicated the t. a. line seems to be a little outcurved 
between the veins, and as a whole a little outcurved in its course. The t. p. line is 
even, with an even outcurve over the cell and an almost equally even incurve. The 
s. t. line is whitish, irregular, broken, well defined by a blackish preceding shade 
and by the somewhat darker terminal space. The claviform is merely indicated by a 
few black scales. Orbicular round, of moderate size, incompletely defined by a few 
black scales, within which is a somewhat more distinct circlet of yellowish scales. 
The reniform is moderate in size, also incompletely outlined by black and yellow 
scales, the lower portion filled with blackish and forming quite a prominent feature in 
the markings of the wing. Secondaries in the male white, with a vague smoky outer 
margin and a narrow discal lunule. In the female more smoky, with a blackish outer 
margin and discal lunule. Beneath whitish, powdery, with a more or less marked 
outer line and discal spot on both wings. Expanse, 1.50-1.60 inches = 36-40 mm. 
Habitat: Colorado. 
I have three specimens, two males and one female, received from 
Professor C. P. Gillette, and numbered 565, 2610 and 2732. The 
specimens differ considerably, and yet resemble each other quite closely, 
The female is the larger and much the darker. All the specimens agree 
in showing the black filled reniform and pale, dark bordered s. t. line, 
as the only prominent features in the wing.
