316 WILLIAM T. M. FORBES 



1. P. confusella Dietz. Fuscous brown, the antemedial band broad, pale, erect, 

 faint and diffuse; some pale scales at anal angle. No other distinct marks. This 

 form looks very much like P. fidella but is browner. 



June. 



Pennsylvania; New Jersey. 



2. P. purpurella Dietz. Blackish, shot with purple; with more or less distinct 

 traces of the usual markings. Head and palpi concolorous. Male unknown. 12 mm. 



June. 



Pennsylvania. New York: Rock City. 



3. P. laticapitella Clemens. Dull fuscous, about the color of P. fidetta; the 

 scales largely pale-tipped, especially on outer half of wing. Antemedial fascia 

 prominent, straight, erect, pale (the curve shown in Dietz's figure is probably an 

 artefact), fairly defined on outer side, but diffuse on basal. Base more solidly 

 fuscous; a broad shade of solid fuscous beyond the fascia to middle of wing. Two 

 blackish discal dots, sometimes obscure, with a bar below them in the fold, all 

 defined by a well-marked pale shade; the apex again darker. Some whitish dusting 

 in base of fringe. 12 mm. 



June. 



New Hampshire; Pennsylvania; Iowa; Kansas. 



4. P. mediofasciella Dietz. Practically like the last form, the marks less con- 

 trasting antemedial fascia narrower, discal dots fused into a vague vertical bar, 

 only faintly defined with pale; white- tipped scaling at apex well marked. 12 mm. 



July 1. 



New Jersey; Pennsylvania. 



5. P. basilarella Dietz. Pale silvery gray, dusted with pale fuscous. Head, 

 thorax, and costal half of fore wing at base with golden iridescence. Fore wing 

 with base paler, and a dark shade beyond the antemedial fascia; a dark streak on 

 fold at a sixth way from base; fascia with a curved projection at the middle; discal 

 dots strong, with a dot below them in the fold, and followed by a waved postmedial 

 shade. Female less iridescent, with third segment of palpus shorter than second; 

 first segment fuscous-dusted, second and third pale. 12 mm. (Not seen.) 



Pennsylvania; Louisiana; Kansas. 



6. P. ornatella Dietz. Similar to P. laticapitella and mediofasciella, the white 

 antemedial fascia striking, and perceptibly excurved on outer side, almost pure 

 white; discal dots separate, dark, faintly set off; the whole apical region with 

 white-tipped scales, paler than the base. 11-12 mm. 



Hazelton, Pennsylvania. 



7. P. angustipennella Dietz. Fore wing narrower (less than one-fifth as wide 

 as long). Lighter mouse gray with a slight violet tint; antemedial band erect, 

 vague, slightly paler. A vague pale area over end of cell with obscure darker 

 discal dots. 11 mm. 



Pennsylvania. 



The one type I have seen looks too similar to P. confusella. 



8. P. tristella Dietz. Mouse gray. Antemedial band, of white-tipped scales, but 

 quite narrow; discal dots practically obsolete, vaguely defined by the well-marked 

 white-tipped scales on the outer half of the wing. All the scales with more or less 

 distinct pale tips. 11 mm. 



Hazelton, Pennsylvania. 



9. P. spoliatella Dietz. Identical with Dryoperia grisella (of which it may be a 

 venational aberration), except for the stalking of M 2 and M 3 . 11 mm. (Unknown 

 to me.) 



Hazelton, Pennsylvania. 



10. P. obscurella Dietz. Fore wing broad, four times as long as wide, mouse 

 gray, immaculate, with ochreous bronzy head and pale palpi. 11 mm. 



July 4. 



Northern New Jersey; Pennsylvania.
