to the discal cross-vein; orbicular only visible as a central pale shade 
and four outer brown dots. Nerves and nervules clothed with black 
scales; on the interspaces intermediately are brown scales, with a 
whitish streak centrally, beneath which, on the subterminal margin, 
are the usual black streaks in all the interspaces, the most conspicuous 
of which is tnat in cell 4 (farther removed from the margin than the 
others). Fringes white, cut with brown on each side of the nervules, 
opposite the interspaceal lines of brown scales; these brown ciliary 
scales of each interspace joined by a brown marginal line. Secondaries 
acute, excavated opposite the cell, slightly dentate ; white, hyaline. 
Nerves and nervules heavily marked with black scales, especially 
toward the margin; no distinct marginal border, but in place thereof 
the extreme margin is brown, with some brown scales extending a 
short distance therefrom, and farther in cells 1 b and 4; some brown 
scales on the costal nervure apically. Beneath, primaries pale brown, 
with an aeneous reflection; a conspicuous brown spot on the discal 
cross vein. Secondaries, with brown scales on the nerves and nervules 
and marginally as above, though less abundantly; sprinkled with 
brown scales costally and in the cell above the fold; cellular fold and 
discal cross vein above it broadly covered with brown scales, diffuse 
on the latter, giving a conspicuous cellular spot; these features seen in 
transparency from above. 
‘Described from two és, differing materially in size; the larger and 
better specimen, from which the features are mainly drawn, measures 
2 inches expanse of wings, length of body 0.86 inch; the other, 1.70 
inches expanse, length of body 0.72 inch. 
‘‘In addition to disparity in size, the two examples differ somewhat 
in shape of wings, those of the smaller being narrower and more 
acute, to the degree that the male usually varies from the female in the 
several species of this genus; yet the two examples are undoubtedly 
maies, a8 is Shown by their frenelum examination. In all other par- 
ticulars, so far as they are traceable, the two are identical. They are, 
unfortunately, in poor condition, and the description above given may 
require correction.” 
HABITAT: California. 
Ihave quoted Dr. Lintener’s description of this species because I 
have only a single male, not in the best condition, before me. It is 
marked ‘“Sauz., Mch. 23, 1878,” and belongs to the U. S. National 
Museum. 
The sexual characters are as distinctive and aberrant as is the anten- 
nal structure. The harpe narrows from a moderately broad base, very 
gradually, to an acute, corneous tip, which is a little curved and beak- 
like. The clasper is a stout, moderately long corneous process, with a 
spoon-shaped tip. 
The insect seems,rare, and it is rather strange that no females have 
been thus far received,
