space paler and with a brick-red tinge. T. a. line upright, or a little outwardly 
oblique, geminate, outer defining line usually very distinct and touching the 
orbicular in its course. T. p. line geminate, inner line darker, included space 
paler; in course it is very even, widely outcurved over the reniform, altogether 
what might be termed S-shaped, with most of lower extension lopped ofl’. The 
s. t. si)ace is pale, except costally, darkening to form a continuous dusky shade 
before tbe s. t. line, which is pale and irregularly sinuate. Tliere is an admix- 
ture of reddish scales in this preceding shade which is most obvious at anal 
angle. A prominent, rigid black line from the costa, forming the inner margin 
of reniform and continued thence to the hind margin at t. p. line. Claviform 
small, indefinite, marked only by a vague brick-red shade. Reniform large, 
kidney-shaped, suffused with brick-red : a black line at base of fringes, which 
have a dusky interline. Secondaries soiled white, veins and terminal line dusky. 
Beneath whitish powdery, with a more or less complete outei' line and discal 
spot. Expands 1.24 — 1.40 inches; 31 — 3.5 mm. 
Hab . — Sierra Nevada, Cal. (Edwards). 
The anteimte of the male have the joints but feebly marked and 
ciliated, not at all serrate, much less pectinated. The transverse 
median line corresponds to the outer defining line of the median 
shade in elda, but is more prominent. The differences in details need 
not be pointed out where structural characters declare the species 
difierent. 
An incomplete specimen is in the United States National Museum ; 
the wings and antennm are, however, perfect, and the specimen is 
one of my types. 
Dryobota. ciirvitascia n. sp. — Asheu-gray or darker, with or without 
an admixture of hiick-red scales, the black maculatiou consisting generally of 
elevated scales, giving the species a rough or “squammose” appearance. Collar 
inferiorly pale, a vague reddish median line, surmounted by an equally vague 
blackish one. Primaries, basal line geminate, blackish, vague, reaching to the 
short black basal dash, along which a brick-red shade is more or less marked. 
T. a. Hue geminate, incomplete, outwardly oblique and slightly curved between 
the veins. T. p. line vague, scarcely definable, obsoletely geminate, evenly out- 
curved over cell, and incurved beneath. The s. t. space is outwardly a little 
paler, a partial series of black or blackish lunules, becoming more distinct toward 
inner margin ; an admixture of reddish in these lunules also increases toward 
anal angle. Terminal space dusky; a blackish terminal line and a narrow pale 
line at base of fringes. Claviform apparently obsolete. Orbicular oblong, ob- 
lique, concolorous, with a narrow black margin and a very narrow white annulus. 
Reniform narrow, quite long, lunate, shot with reddish, defined by black and 
white scales rather than lines. A dusky median shade, feebly Insinuate, touch- 
ing neither of the spots and reaching margin between the ordinary lines. Sec- 
ondaries soiled white or smoky, with a blackish terminal line. Beneath pow- 
dery, pale, with a variably distinct discal spot and outer line. Expands 1.12 — 
1.20 inches ; 28—30 mm. 
Hab . — Sierra Nevada, Cal. (Edwards), September ; Placer County, 
C'al., through C. V. Riley.
