NOTHLOBA, new genus. 
Fore wing.—in the male very broad, the hind margin longer than 
the inner; the lower two-thirds more oblique than the upper third; 
in the female the hind margin is not so long as the inner margin. 
Hind wing.—Small, especially in the male, with a small flap at 
base of inner margin in that sex. 
Abdomen stout, and in the males elongated; palpi porrect, hairy, 
the last segment drooping; antenne as in Rhopalodes,; tongue and 
frenulum present, hind tibize with 4 spurs. 
Neuration.—Fore wing, as in Physoloba; hind wing in female also 
as in Physoloba, in the male the subcostal is separate from costal, 
but united at end of cell by a bar; 6 and 7 stalked; 6 reaching hind 
margin below middle; no radial visible; only two veins from the 
lower end of cell; inner margin with a full fringe and somewhat 
thickened. | 
Ty pe.—N otholoba schausi Warren. 
The discocellular in hind wing of the female is slightly triangulate 
and the radial rises from the lower angulation. 
NOTHOLOBA SCHAUSI, new species. 
Fore wing.—Grayish white, tinged with brown in basal and mar- 
ginal areas; basal patch very small, limited by a dark band between 
two lines angled on median; inner edge of central fascia sinuous at 
one-third, followed by a grayish brown band; outer edge at two- 
thirds, bluntly angled at 6 and 4, then incurved, lunulate-dentate, 
the teeth pointing basewards and well marked, preceded by two sim- 
ilar lines and below costa by a brown band, the teeth on the veins 
running in to the inner band; a blackish linear cell spot in the cen- 
tra] pale area; interval before fascia with the center brown edged 
by pale bands with a gray line down them; band beyond narrow, 
with a gray middle line; submarginal line pale and waved, preceded 
by a brown tinge, which forms blotches at costa and beyond cell, 
with the lunules outwardly edged with blackish; pairs of blackish 
marginal spots at the vein ends; fringe mottled dark and lght gray. 
Hind wing.—Rufous gray, along the costa whitish. 
Under side rufous gray, the fore wing whitish along inner margin ; 
the markings all showing slightly. 
Head, thorax, and abdomen pale gray; the metathorax with a pair 
of dark spots; the segments of dorsum with blackish pale-edged 
rings. 
The female is paler, with the bands blacker, but the insect is not 
so fresh as the male, which probably accounts for the difference. 
Hupanse of wings.—Male, 36 mm.; female, 40 mm.
