not spring from one point. I should precede Omf^lialocera with, both 

 these Western genera. 



Prorasea simalis, n. s. 



S 9 . Ocherous, sometimes more or less fuscous or blackish, variable 

 in tone. Fore wings with indistinct oblique lines, flecked with white. 

 Median space ocherous, narrowed below median vein. Median lines 

 dark, fine, the outer much projected subcostally, oblique. Subterminal 

 space fuscous or ocherous. Subterminal shade white, more or less in- 

 distinct superiorly, with a notch on submedian fold. Biscal dots with 

 a white spot between them at the place of the reniform ; this discal mark 

 often difficult to make out. Fringes white at base, interlined. A ter- 

 minal punctiform black or dark line. Hind wings smoky-fuscous, paler 

 at base, with an external line picked out by a following pale shade, and 

 submedially sometimes white-flecked. A terminal, blackish, punctiform 

 line. Fringes white at base, doubly interlined. Beneath pale, soiled 

 yellow-fuscous with fine, common, exterior line and short double lines 

 on primaries in place of the discal mark. White shades accompany the 

 median lines on the primaries above. Body fuscous-ocherous, paler 

 beneath. Expanse, S ,22', 9 , 26 to 29 mil. Eight or ten specimens ex- 

 amined under the number "5939", and collected by Mr. Hy. Edwards 

 in Oregon. Also collected by Hayden's Sur^^ey in Montana. 



Aedis, n. g. 



Front narrow, smooth, clothed with thin, converging squamation. 

 Ocelli prominent. Maxillary palpi linear, as long as the second article 

 of the labial palpi, these latter narrow, with moderate third article. 

 Male antennae scaled above, ciliate beneath, the joints improminent. 

 The supracaputal scales diverge between the antenuse at base, forming 

 two inconspicuous, decumbent tufts. Wings ample. Fore wings 12- 

 veined ; veins 4 and 5 separate, 5 near 4 from the cross-vein j 9 out of 

 8, a short furcation to costa. Hind wings 8-veined ; 3 just before the 

 lower angle of the cell, 4 and 5 together from the lower angle of the cell, 

 which is closed, 8 out of 7 beyond 6. This form seems to have some 

 resemblance to ExarcJm in the shape of the wings. In the neuratibn 

 of primaries, it agrees with Prorasea. 



Aedis funalis, n. s. 



S 9 . Primaries whitish-gray or brown. Outer transverse line black, 

 distinci}; inwardly oblique, a little rounded below costa. Between this 

 and the base the markings are obsolete. Beyond it, the wing is shaded 

 with bright brown, especially centrally. Some black streaks below apices 

 and at internal angle before the narrow subterminal line. Fringes dark. 

 Hint! wings pale fuscous; fringes narrowly interlined. A fine, dark, 

 sometimes punctate, terminal line. Hind border touched with fuscous. 

 An outer transverse line distinct over the middle of the wing. Beneath
