Palpi long recurved, slender, smooth, third segment a little exceeding 

 the second, acute; antennae a? in Perimede, basal segment somewhat 

 elongate, slightly clavate, stalk serrate near apex. Fore wings with- 

 out scale tufts; ib furcate, 2 from very near angle of cell (opposite 

 origin of 10), 3 from angle, 4 remote at origin, but curving immedi- 

 ately downward toward 3, 7 and 8 stalked, 6 out of 7 near apex, n 

 from middle of cell. Hind wings 1-2, linear lanceolate, 2, 3. 4 parallel, 

 equidistant, 5 approximate to or connate with 4, 6 and 7 long stalked, 

 cell open between 5 and 7. Hind tibiae rough haired above. 



Apart from the stalking of 6 with 7 in the fore wing, and 

 the stalking of 6 and 7 of hind wing, the position of vein 2 

 of fore wing is the chief difference 1 between this genus and 

 Perimede, where this vein arises but slightly beyond n. The 



o 



hind wings are much narrower, with more deeply excised 

 costa and pronounced costal shoulder. To Chambers' genus 

 Eriphia it has no resemblance. 



In addition to these structural differences, Illwme itnima- 

 culella differs from Perimede erransella by its smaller si/e 

 (7.5-9 mm.), the series of distinct white spots on the under 

 surface of the third palpal segment (varying in number from 

 four to seven, including the white extreme apex as a spot), 

 the absence of markings except the costal spot before the 

 cilia, a very minute plical spot, and the immaculate under sur- 

 face of the wings. As both species easily become worn on 

 the upper side, and a slight abrasion produces a sordid whitish 

 spot, the palpal markings and the immaculate under surface of 

 the wings are the most reliable characters. 



Perimede falcata n. sp. 



Head and thorax shining whitish gray, densely dusted with fus- 

 cous; palpi shining grayish brown with the upper sides whitish, lower 

 surfaces faintly hoary. Antennae dark grayish fuscous. 



Fore wings shining grayish white almost overlaid with purplish 

 fuscous dusting. Three spots of raised black scales margined with 

 white inwardly, the first in the fold sometimes elongate, the second 

 in the middle, the third at the end of the cell; a whitish costal spot 

 at the beginning of the cilia and an opposite dorsal one. A black spot 

 in apex, margined inwardly with white scales; a series of minute 

 raised black specks along the termen, usually with whitish scales h<>r 

 dering them inwardly. _ Cilia along costa to a point opposite apex 

 dark fuscous, beneath apex for about half the termen white, rest of 

 cilia dark fuscous, the line separating the white from the HIM on-, 

 terminal cilia curving obliquely across the cilia. Under surface oi
