14. T. clavana Fernald. Fore wing light powdery blue -gray, the basal half 

 light brown except on the inner margin ; costal edge white, more narrowly so 

 toward the base than in T. striata-na, and cut by brown bars its whole length, those 

 on the basal half finer and shorter than those outward. A white band along lower 

 edge of cell, outwardly broken into streaks extending to the speculum, and with 

 a black dash below it ending abruptly at the middle of the wing. Speculum pale 

 yellow, preceded by a fine black line and containing a couple of dots. Apex drawn 

 out as in T. striaiana. Hind wing brownish gray; fringes pale. 15 mm. (I have 

 seen this species labelled tenuiana Walsingham). 



Hampton, New Hampshire; Truro, Massachusetts. "New York" (Heinrich). 



1;3. T. kiscana Kearfott. Nearly even, pale gray. Wing form as in T. striatana 

 Fore wing with costa broadly but a little diffusely white; outwardly strigose with 

 luteous and blackish; the white extending halfway across the cell on the basal 

 half, but narrower outwardly. Inner margin more or less shaded with whitish; 

 speculum white or pale yellow, preceded by a broken black line and containing 

 two black bars. Fringe powdery. Hind wing with dark veins. 12 mm. 



End of May. and June. 



Cincinnati, Ohio; New Jersey; District of Columbia. 



16. T. ochroterminana Kearfott. Dull black; roughly scaled; outer fifth, includ- 

 ing fringe, contrasting ochre yellow, somewhat mottled, preceded by a yellow - 

 brown streak on dorsal half of wing. 10-15 mm. 



August and September. 



Kennebunkport, Maine, and Maryland to Manitoba and- Illinois. New York: 

 Potter Swamp (Yates County). Ithaca. 



17. T. perfuscana Heinrich. Deep brown, mottled, made up of black-brown, 

 chocolate brown, and some flecks of paler gray-brown; speculum lighter, deep 

 ochre, flanked by two vertical lead-gray bars, and containing three black lines. 

 Antemedial band broad, strongly excurved, formed of a gathering of the fuscous 

 flecking; postmedial traceable at costa only. 12 mm. 



August. 



New York and western Pennsylvania. New York: Ithaca. 



18. T. raracana Kearfott. Red-brown or, more rarely, chocolate brown, shading 

 into light red-brown toward base, especially on costa. Costa with light gray- 

 white striae. Speculum contrasting pale yellow, with broad silvery bars and some 

 broken black markings. Fringe powdery gray at apex, light yellow-brown below. 

 12 mm. 



This form can be distinguished from the similarly marked Eucosmae by its brown 

 or reddish, rather than fuscous, color. In pattern it is very near T. formosana. 

 It has been taken in August, and. southward, in May also. 



New Jersey and western Pennsylvania to Texas and Florida. 



19. T. tomonana Kearfott. Pale gray, somewhat strigose with duller light gray; 

 the speculum represented by some black dots. Two contrasting blackish spots on 

 inner margin, the basal one half-crescentic, the outer half -elliptical or more 

 irregular, extending less than a third way across wing, but broad. 12 mm. 



August and September. 



St. Johns, Quebec; New Jersey; western Pennsylvania. New York: Ithaca. 



20. T. imbridana Fernald. Ground pale yellow, overlaid, except toward base of 

 costa, with rusty ochre; mottled irregularly with dark brown, with a strong 

 purple iridescence in some lights; the purple -brown gathering to form a band from 

 the middle of costa to inner margin before speculum, and another from this band 

 where it crosses the cell to inner margin at a third way out, both sometimes broken 

 up "or obscured by brown siiffusion. Outer part of costa also showing the yellow 

 ground, and striate with brown. Speculum luteous with three broken black bars. 

 Hind wing light gray. 



General in distribution; flying in August.
