1. L. tricristatella Clianibors. Dull brown, slightly shining, the scales of the 

 paler portion pale-barred and tipped. Markings mostly indefinite. Inner margin 

 slightly paler toward base, apex distinctly paler, tending to show a pale sub- 

 terminal costal patch. The principal tufts are a median one below fold, and one 

 at end of cell. 20 nun. (graiidisella Chambers, siibiridescetis Walsingham.) 



May and June. 



Ontario to District of Columbia and Colorado. Xew York: Uphill Brook (Mt. 

 Marcy). 



2. L. eloisella Clemens. White. Palpus with two black bars. Fore wing with 

 black dot at base, one on costa a fourth way out, and a small tuft on the fold 

 opposite it. Outer half heavily streaked with yellow-brown; two broad streaks 

 converging on apex from costa at three-fifths and four-fifths way to apex, each 

 sometimes divided into two lines; two finer lines beyond middle of disc, meeting 

 at the upper edge of a large brown, white, and gray tuft three-fourths way out. 

 A smaller black spot near middle of inner margin, followed by a brown triangle 

 just reaching this tuft; a powdery gray patch below apex. Fringe with a strong 

 black pencil projecting from apex; with two triangular teeth on costal side, each 

 edged with black. The yellow-brown may lie partly replaced with black. lv> mm.

Generally distributed; in .June. Larva yellowish white, with red-brown head; 

 in pith of (Knothera stems, wintering in the dry stems. 



3. L. passerella Busck. Venation as in Psacaphora; wing-form and pattern as in 

 L. eloisella. Pet-ten present. White; palpus with a gray spot on second segment; 

 fore wing with two black dots at base, a streak on costa a third way out, a broad 

 light brown median fascia, and a postmedian one separated by a narrow white 

 area, both further out in the middle, irregular, and defined with black scales. 

 Apex with mixed brown and black-and-white-barred scales, with a longitudinal 

 black streak from the outermost dorsal tuft to the apex. A transverse black line 

 across fringe at apex. Basal two-thirds of hind wing black, the rest fuscous. 

 7 mm. 



East River. Connecticut. Xew York: Xew Y'ork City (Watson). 



6. FSACAPHORA Herrich-Schfpffer 

 (Lophoptilus, Laverna, Mompha, in part) 



Pecten rudimentary. Palpi rather thick, but smooth, third segment much 

 shorter than second; venation as in Lophoptilus, but with R of hind wing reach- 

 ing costa only two-thirds way to apex, like R, of Tinagma. 1st A stalked (fig. 

 187). Fore wing typically with slightly raised metallic markings.

1. P. (?) cephalanthiella C'haml>ers. Powdery gray, obscurely mottled. Head 

 cream-white, contrasting. Fore wing with markings all obscure, the distinctest 

 being dark dashes in fold at base, and in middle of wing toward apex, of black 

 scales and an antemedian silvery white spot in cell, one in fold before middle, and 

 one at end of cell. Some of the dark scales also shining lead gray in some lights. 

 Black dorsal tufts at two-fifths and three-fourths way to apex. 7 mm.
