AMERICAN MICROJ.EPIDOPTERA. 105 



ground color a sordid white, with an ochreous tinge, overlaid with fuscous scales, 

 a strongly curved pale fascia at one-third, illdefined toward the base, convex 

 externally, and equidistant from the base at both margins of the wing, extreme 

 costa deep fuscous; basal space darker towards the base, especially adjacent to 

 the margins; middle part of wing dark fuscous in the costal half of the wing, 

 paler towards the inner margin. Opposite the beginning of the costal ciliaj is a 

 triangular space, dusted over with white scales and limited towards the apex by 

 a darker, zig-zag fuscous line, within this space are two dark spots at end of 

 cell and a short line on the dorsal margin immediately beneath ; apical part of 

 wing and adjoining cilia sparsely dusted with fuscous scales. Hind wings and 

 cilia of both wings greyish fuscous. Under side: thorax and femora silvery 

 white; abdomen greyish fuscous, legs fuscous, with paler scales; tarsal joints 

 tipped with paler; wings fuscous. 



In the female the head and antennal eye-caps are darker, a;neo-fuscous ; labial 

 palpi dark fuscous, apices of second and third joints a little paler, somewhat com- 

 pressed, the latter distinctly shorter than the former. 



Expanse 10.-12. mm., .42-.48 inch. 



Hab.—Fa. ; N. J. . 



Probably occurs over the whole Atlantic district ; attracted by 

 light, June, July. Varies in extent and intensity of the dark shad- 

 ings of fore wings. Superficially, scarcely to be distinguished from 

 Ploiophora ampla, the difference in the labial palpi will prevent 

 confusion, third joint in the fen)ale of the latter species being longer 

 and depressed. The fascia of fore wing is more strongly curved in 

 confusella. From laticapitella the present species differs by the longer 

 labial palpi of the female, second joint longer than the third, and 

 the more strongly curved fascia. 



P. purpurella sp. n. — Dark brownish fuscous; thorax, head and antennal 

 eye-caps jeneo-fuscous, with strong lustre; antennse dark, blackish. Lal)ial 

 palpi (female) distinct, dark fuscous, a narrow ring at apex of second and extreme 

 apex of thii'd joint paler ; latter much shorter than the former ; fore wings : costa 

 feebly convex from base to apex, slightly depressed along middle third ; dee]i 

 fuscous brown, overlaid with purple, basal space scarcely paler, limited externally 

 by a regularly curved line, convexity toward the apex and equidistant from the 

 base at both margins ; stigmata illdefined ; apical part and base of cilia thinly 

 sprinkled with white scales; cilia with three or four indistinct paler lines; hind 

 wings greyish fuscous, cilia paler towards the base. Under side: body and 

 femora silvery grey, tinged with fuscous, last ventral segment with fulvous 

 scales ; legs fuscous, tarsal joints with a pale annulus at their apex ; wings dark 

 fuscous. 



Expanse 11.5-13. mm., .46-.52 inch.
