OF WASHINGTON. 35 
Outer line whitish, diffused, scarcely darker edged within, bent inward 
rather sharply on both folds. A terminal row of black dashes. Expanse 
22-25 mm. 
Two specimens, Chicago, 111. (A. Kwiat). The female was 
sent me some time ago by Mr. Kwiat for name, the male I have 
just received through Mr. Kearfott. The species is near to 
mirandella Rag., but much darker in color. I have named it in 
honor of the discoverer, though I am not sure that he will recog- 
nize his name in the Latin form. 
Type. No. 8186, U. S. National Museum. 
Salebria yumaella^new species. 
Fore wing gray, black coarsely powdered on a white ground, nearly uni- 
form. Lower half of basal space darkened. Inner line somewhat curved 
S-shaped, black on the upper cusp, white on the lower; discal dots black. 
Outer line white, doubly black edged, the black increased at apex, bent in 
on both folds. Terminal dots black, powdery, confluent. Hind wings 
whitish. Expanse 18 mm. 
One cT, Yuma Co., Arizona (collection of W. D. Kearfott). 
Type. No. 8191, U. S. National Museum. 
Allied to odiosella Hulst, bakerella Dyar and bifasciella Hulst. 
From the latter it is separated by the absence of the lower half 
of the inner black line ; from the two former, by the smaller size 
and narrower markings. 
Salebria nogalesella,' new species. 
Dark bluish gray, cinereous and blackish scales mixed. Basal space 
lighter outwardly. Inner line broad, black, divided by a narrow, pale, 
zigzag line. Discal spots joined. Outer line curved at discal fold, straight 
and crenulate below, pale, finely black edged within. A terminal row of 
black dots. Hind wings subpellucid yellowish fuscous, darker on the edge. 
Expanse 20 mm. 
One cT, Nogales, Arizona (E. J. Oslar). 
Type. No. 8192, U. S. National Museum. 
This falls near Meroptera pravella Grote, but looks so differ- 
ently that I cannot leave it under that label. The markings 
are about the same, but the color is brighter gray and more 
powdery. I have compared also the descriptions of Meroptera 
umnella Rag., and Salebria subfuscella Rag., which are very near 
to pravella if not synonymous therewith; but do not find that 
they apply to nogalesella. 
Megasis aridella^f new species. 
Fore wings nearly white with blackish shadings, faintly ocherous in the 
terminal space, all the veins lined with black. Inner line broken, showing 
an angle on vein i and a patch on the median vein and on costa; two discal
