Forewings, dark brown, chestnut brown on the basal part of the costa, and over- 
laid to a great extent with white scales, especially along the veins which are indi- 
cated by white lines. The inner cross-line is not indicated. The outer cross-line is 
white, nearly parallel with the outer border, and nearer to it than to the end of the 
cell, wider on the costa than elsewhere, and not quite reaching the hind margin. 
Terminal line, dark brown, bordered on the inside by a wider white line. 
Fringes, pale yellowish, with a darker line through the basal j>art. 
Hind wings, light ash gray, with a darker terminal line preceded by a light line. 
neither of which reaches the anal angle. The outer cross-line, which is scarcely vis- 
ible, extends from the outer fourth of the costa nearly straight to a spot near the 
end of vein 2. 
Fringes white, with an ash gray line near the base. 
Under side of the fore wings, ash gray, lighter on the costa and beyond the cross- 
link, which shows faintly. Under side of hind wings silvery white, grayish along 
the costal portion : the beginning of a cross-line on the outer fourth of the costa. 
All the wings have a terminal row of dark points beneath ; those of the hind wings 
do not reach the anal angle. Under side of the body and of the legs silvery white. 
Described from one example in the National Museum, taken on the 
Argus Mountains. California, in April, 1891. 
Titanio proxiinalis n. sp. 
Expanse of wings, from 20 to 25 mm. Head, thorax, upper side of abdomen, and 
fore wings dark brown, overlaid more or less with whitish scales. The outer cross- 
line is represented by an ill-defined, dentate, dark brown line crossing the wing 
about halfway between the end of the cell and the outer border, and beat in below 
the cell. This line is margined imperfectly with cream white. 
Hind wings, orange red, with a narrow, terminal, dark brown border. 
Fringes of the same color as the border. 
Under side of all the wings orange red. with brown fringes, and an oblique brown 
streak on the cross- vein. 
A variety of this species has the hind wings orange yellow. It was 
taken on the Argus Mountains, California, April, 1891. 
One example in ray collection and two in the collection of the National 
Museum, collected in San Bernardino County, Cal. 
This species is most nearly allied to Titanio super ua, of Europe. 
Metasia argalis n. sp. 
Expanse of wings, 20 mm. Head, thorax, and fore wings straw yellow, sprinkled 
more or less with brownish scales. Labial palpi brown on the outside and white 
beneath. 
The fore wings have the base, above the median vein out as far as the inner cross- 
line, thickly sprinkled with brown scales. The cross-line is oblique to the median 
vein, where it bends and runs nearly at right angles to the hind margin. The orbic- 
ular andreniform are strongly marked, and sprinkled within with brown scales; the 
former is slightly oblique; the latter straight on the inner side, and with a short, 
blunt outward tooth at the end of the subcostal vein. The outer cross-line starts 
from a point on the costa halfway between the reniform spot and the apex, and runs 
parallel to the outer margin, to a point between veins 5 and 6, giving off a single 
blunt tooth in the middle of its course, then, curving around beneath and touching 
the lower end of the reniform, continues obliquely inward and downward to a point 
below the orbicular on the fold, then runs to a point near the outer fourth of the hind 
margin, forming an inward angle on the fold and an outward angle on vein 1. The 
terminal space is sprinkled with brown scales quite densely along the inner edge, 
and especially below the cell, and is separated from the cross-line by a narrow clear
