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 markirjgs 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.
