General color ash gray, with a slight reddish tinge. Head fuscous 
on front, paler on vertex; collar with a black line near tip; thorax with 
a small black central tuft, and a lateral line on patagie at the base of 
the wings. Primaries, basal line marked only by a geminate costal: 
spot; acurved black mark from base below median vein to the subcostal 
vein near the t. a. line; above this the color is pale, beneath much 
darker and tinged with fuscous. T. a. line very variably distinct, gem- 
inate, often only the somewhat paler included space obvious, inner line 
never distinct; in general course it is somewhat oblique outwardly, -a 
little curved between veins. T. p. line more or less indefinite, always 
traceable, dusky, better marked in costal region, where it is geminate. 
It is rather distant from base, well outcurved over the reniform, but not 
much ineurved below. Between the ordinary spots a median shade 
darkens the intervening space, theuce continues as a narrow and rather 
faint line, nearly upright in course, to the hind margin. 5S. t. line pale, 
marked on either side by a blackish shade which is broader in the 
terminal space, making a feeble \/W on veins 3 and 4, in some specimens 
much less marked and almost even. Claviform small, black ringed, con- 
colorous or somewhat darker; beyond it the submedian interspace is 
paler to the s. t. shade. Orbicular large, pale, oval, superiorly open to 
the costa. Reniform moderate, upright, with a median brownish-red 
shade, inferiorily darkened also by the median shade. Beyond the 
middle a pale shade extends to thes. t. line. Thes. t. shade consists 
rather of a series of closely connected interspaceal lunules, of which the 
central are in rare cases obsolete. Secondaries whitish, with a distinct 
discal dot, a more or less obvious exterior line and with fringes cut with 
black. Beneath, primaries smoky, secondaries white; both with an 
exterior line and discal dot. 
Expands 27 to 31 millimetres=1.10 to 1.25 inches. 
HABITAT: California. 
Several specimens are in the collection of the U.S. National Museum, 
all from California (O. Meske; Alameda County, January, through C. 
-V. Riley). 
The species is easily recognizable by the small size, combined with 
the very long pectinations of the antenne and large, distinct, ordinary 
spots. 
The genitalia have the harpes bent toward tip, and tapering to an ob- 
tuse point; the clasper is chitinous, stout, rather long, curved some- 
what more than the angulation of the harpes. The species seems not 
uncommon, and is one of the most generally represented in collections.
