scaling; s.t. line as a shade rather than a definate line, strongly bent in almost 

 touching t.p. line near vein 5 ; fringe deep slate-gray with some white, but 

 not definitely checkered. Secondaries : pale, suffused with fuscous basally, the 

 veins somewhat tinged with fuscous, with crescent shaped discal spot and broad 

 outer black band ; fringe nearly pure white with a faint interline toward the 

 base. Beneath: presenting a pale appearance; the primaries somewhat suf- 

 fused, with blackish discal lunule and trace of s.t. and t.p. lines ; the secondaries 

 white, with some fuscous hairs basally, black discal lunule, trace of a median 

 line formed by fuscous scales on the veins, and an outer blackish band. 



Expanse: 26-28 mm. 



Genitalia: Uncus sharply pointed, heavily chitenized; anus membraneous; 

 valves bilaterally symmetrical ; corona present ; true claspers apparently as mere 

 folds at the cucullus ; sacculus extending in a long, rather broad arm, its caudal 

 edge serrate, with an additional finger-like projection ; an additional clasper- 

 like flap of membrane present only as a fold near the cucullus (see Anarta 

 staudingeri) near the base of which is a second lobate flap ; clavus unarmed 

 except by sensory hairs; peniculus, absent; juxta not heavily chitenized, its 

 caudal end invisable; penis armed with a heavy row of small spines only. 



The present species, because of the serrate antennae is tentatively 

 placed at the head of the genus Anarta. It is apparently closely allied 

 to Anarta staudingeri. It has heretofore been confused with A. staud- 

 ingeri in the Barnes Collection. A series of fine specimens have been 

 received thru the kindness of Mr. George P. Engelhardt, which show 

 considerable variation in color and minute details of maculation, but 

 in general the species presents a homogenous appearance.

Anarta poca sp. nov. 



Antennae of male moderately serrate and fasciculate, yellowish. Head and 

 thorax variable ; olivaceous in male, grayish in female ; mixed with brownish, 

 black and white. Abdomen whitish-gray in female, somewhat more luteous in 

 male. Ground color of primaries blackish, mixed with a considerable dusting 

 of white scales. Basal line obscured; t. a. line black, waved from costa to clavi- 

 f orm, drawn inwardly V-shaped in submedian fold ; white edged mesally, the 

 white faintly edged by a few black scales, thus tending to make a geminate 

 t. a. line; claviform bordered by a black line, filled with ochreous; orbicular 

 white, surrounded by a faint black line, and with a grayish center; median shade 

 present, black, almost lost in the dark ground color; reniform whitish, kidney
