AMERICAN MICROLEPIDOPTEKA. 103 



Two species are recognized : 



Anterior wings less elongate, fascia feebly curved (PI. VI, fig. 1) ailipla. 



Anterior wings more elongate, fascia strongly curved toward the dorsal margin 

 (PI. VI, fig. 2) fidella. 



P. aiiipla sp. n. (PI. VI, fig. 1). Male. — Greyish fuscous; thorax, head and 

 antennal eye-caps greyish luteous, with metallic lustre, antennae dark fuscous. 

 Palpi pale ochreous, second joint dusted with fuscous above its inner, surface 

 smooth and surrounded by dark brown scales. Anterior wings four times as 

 long as wide; costa nearly straight for three-fourths its length, dusted with dark 

 fuscous scales, more dense along the costa and on the fold, the whole wing has a 

 somewhat brassy reflection. A whitish fascia at one-third the wing length, rec- 

 tangular to the margins and faced externally by a line of dark fuscous scales; 

 two dai'k fuscous dots at end of cell and a third one immediately below near the 

 end of the fold, this latter is a trifle nearer the base. Cilia concolorous and like 

 the apical part of wing, dusted with dark fuscous and some scattered white scales. 

 Hind wing grey, fuscous towards the apex. Abdomen above dark fuscous, first 

 two segments more tawny, with a feeble cupreous lustre. Under side : thorax 

 and femora silvery, tinged with fuscous; abdomen anterior and outer side of 

 middle and hind legs brownish fuscous, inside of latter silvery, tinged with och- 

 reous; apex of tarsal joints with a pale annulation ; fore wings dark fuscous, 

 hind wings a little paler. 



Expanse 12. mm., .48 inch. 



Hah. — Hazleton, Pa. 



All the specimens before nie are males ; a female specimen in poor 



condition I refer with some hesitation to the present species ; it has 



the labial palpi fuscous externally, yellowish fuscous on the inner 



.side ; fascia of fore wings indistinct.

I*, fidella sp. n. (PL VI, fig. 2). Male. — Pale greyish fuscous; head and 

 antennal eye-caps paler, tawny, with scarcely any metallic reflections, antennae 

 dark fuscous. Labial palpi of male pale yellow, sprinkled with fuscous scales 

 above. Fore wings more elongate, five times as long as wide; costa slightly re- 

 tuse along the middle, dark fuscous; basal space limited at about one-third the 

 wing length by a fascia, strongly curved inwards towards the dorsal margin ; a 

 paler space in disk beyond the middle, enclosing two dark fuscous dots at end of 

 cell ; apical part of wing and adjoining cilite dusted with dark fuscous, with a 

 sprinkling of white scales, cilia greyish fuscous; hind wings greyish fuscous, 

 cilia the same. Abdomen greyish fuscous, with some metallic lustre above. 

 Underside: thorax and femora silvery white; anterior legs and outer side of 

 middle and hind legs fuscous, the latter ochreous-white on inside; tarsal joints 

 obscurely annulate at the apex ; wings fuscous. 



In the female, head, thorax and antennal eye-caps darker than in the male, with 

 stronger metallic reflections, the labial palpi fuscous, especially towards the apex. 



Expanse 11. mm., .44 inches. 



i/ct 6. — Hazleton, Pa. 



Not rare at electric light. Males predominate. I have but one
