teristic; considerable variation is shown in the subterminal shading. 
We take pleasure in dedicating this species to Mr. J. A. Grossbeck, the 
well known student of Geometridae. 
EvEMERA IMMACULATA sp. nov. (PI. VIII, Fig. 2). 
$. Head, thorax and abdomen gray; primaries pale smoky-brown, more 
ochreous along costa and outer margin, which are thickly sprinkled with smoky 
atoms; faintest trace of a smoky postmedian line bent outwards around cell, 
not attaining inner margin; fringes gray; secondaries pale smoky, veins and 
outer margin slightly ochreous; fringes gray. Beneath primaries deep smoky 
brown, costa and apex gray, sprinkled with brown; secondaries even gray with 
heavy brown sprinkling and distinct discal dot. Expanse 29, mm. 
Hasirat. Loma Linda, S. Calif. (July 8-15) (G. R. Pilate) 1 g. Type, 
Coll. Barnes. 
The species resembles simularia Tayl. in general color but is paler, 
and the lack of maculation on both upper and under sides renders it 
easily distinguishable. 
SELIDOSEMA NIGRICARIA sp. nov. (PI. VII, Fig. 11). 
@. Primaries blackish, sprinkled, especially in median area, with white 
scales; antemedian line narrow, deep black, bent below costa and inwardly 
oblique to inner margin; median line broader, black, parallel to preceding line, 
beyond it a narrow discal dash; postmedian line slightly sinuate, scalloped be- 
tween the veins, especially prominently between veins 1 and 2; subterminal line 
represented by white, diffuse, slightly scalloped markings preceded by slight black 
shading more prominent in central portion; terminal lunate black line; fringes 
deep gray. Secondaries with markings of primaries repeated except that ante- 
median line is wanting; subterminal line at times shows distinctly as a black 
line, bordered on both sides by white, but usually the white predominates and 
the black line cannot be traced; median area paler, due to sprinkling of white 
scales, with small discal dot. Beneath pale, silky, immaculate, sprinkled more 
or less strongly with smoky; small discal dots. Expanse 32-36 mm. 
Hasitat. Palmerlee, Ariz. (C. Biederman) 1 6, 5 @. Types, Coll. 
Barnes. 
The species resembles gnophosarium Gn. but can be most readily 
separated by the fact that the discal dots are punctiform and do not 
form ringlets: Our ¢ is in poor condition but possesses the hind 
tibiae which are without hair pencils so the generic reference is fairly 
certain. 
SELIDOSEMA PURPURARIA sp. nov. (PI. VII, Fig. 5). 
@. Head, thorax and abdomen suffused purplish gray, latter paler at base 
with slight black banding at rear of segments; primaries purple-brown, shaded 
with pale reddish-brown along inner margin and subterminally; antemedian
