Mr. Grote's descriptions are as follows: 



^'■^[adoixi hiio'puncta, Grote. — Primaries dark-shaded pearly gray, 

 finely irrorate with black scales, with three nearly equidistant trans- 

 verse even brownish lines preceded by pale coincident shades, the first 

 line nearer the second, while the third is slightly arcuate, continued 

 from apices to internal margin within the angle. Between the first 

 and second lines a black dot on the disk, the orbicular. Beyond, but 

 approximate to the second line, a larger black dot, the reniform. A 

 series of minute interspaceal terminal dots. These are more continu- 

 ous on the pale secondaries, which show a discal dot beneath. Legs 

 darker than the body parts and abdomen above. Expanse, 20 to 22 

 mm." 



^^Saliariifa, n. s. — Primaries brownish gray, crossed by three oblique, 

 yellowish, narrow lines. Inner line with a costal projection. The first 

 discal dot is close to it. The middle line is a little waved and followed 

 by a diffuse black shading, which obscures the outer discal dot. The 

 outer line is a little bent at the middle, and loses itself to apex. The 

 subterminal field which follows is sufiused with reddish brown and lim- 

 ited by a very fine irregular line ; terminally the wing is again brownish 

 gray and shows a fiiint festooned line; fringes paler, a little brownish. 

 Hind wings fuscous gray with brownish fringes beneath, with black 

 discal dot and outer liius the surface paler, irrorate. Arizona Coll.. B.
