1. Yellowish. 

 2. Reticulate with dark and obliquely shaded. 



3. Ground olivaceous to light ochre 5. alleniana. 



3. Ground brown 6. symphoricarpana. 



2. Not reticulate. 



3. Male with costal fold; shading on under side of fore wing and upper 



side of hind wing light brown; wings more acute 3. clemensiana- 



3. No costal fold; hind wing shaded with gray, or pure white; fore wing 

 with costa more arched and apex blunter 4. pallorana. 



I. Male icith a short costal fold, hardly reaching base of wing, and bearing a fan- 

 shaped tuft of long scales at middle, extending doivn over costal part of wing. 



1. T. affiictana Walker. Pale gray, with base, an oblique fascia across middle, 

 a costo-apical triangle and a vague shade on outer margin darker; defined with 

 fine black strise. Antemedial line angled at middle. Ground more or less dis- 

 tinctly reticulate. Hind wing slightly duller gray. 1S-22 mm. (fuscolineana) . 



May. Caterpillar on fir. 



Newfoundland to Texas and California. Xew York : Ithaca, Albany, New 

 Windsor. 



2. T. packardiana Fernald. Fifth report United States Entomological Com- 

 mission (Forest Insects) 849. A black, gray, and white species from fir, which 

 I have not seen. 



3. T. clemensiana Fernald. Fore wing long and narrow, nearly three times as long 

 as wide, and falcate in the female. Fore wing plain straw yellow, in variety 

 nervosana Kearfott lightly veined with gray. Hind wing and under side of fore 

 wing white, shaded, at least in male, with pale brown, leaving the costa white. 

 16-20 mm. 



Common in May and June, and in August. Female somewhat narrower-winged 

 than pallorana. 



Generally distributed. New York: Peru. Newport, Lewiston, Honeoye Falls, 

 Rock City (Cattaraugus County), Potter Swamp (Yates County), Ithaca, Big 

 Indian Valley, Utica, Albany, New Windsor, Staten Island, Brooklyn. Variety 

 ucrrosana Kearfott occurs at Peru and Ithaca. 



II. No costal fold. 



4. T. pallorana Robinson. Similar to T. clemensiana, but without costal fold; 

 on the average little larger, especially in female (30 mm.) ; hind wing a little 

 grayer in male, normally white in female; fore wing a little duller, not veined 

 with gray. 20 to 25 or 30 mm. (Male lata, female pallorana Robinson.) 



June and July. Larva on cherry, Silphium, and Verbena. 



Massachusetts to Illinois, Missouri, and Texas. New York: Newport, Honeoye 

 Falls, Batavia. Potter Swamp (Yates County), Ithaca, Albany. 



5. T. alleniana Fernald. Light yellow -brown, crisply reticulate with brown; 

 with a vague darker oblique fascia and a costo-apical patch, the fascia tending to 

 be lost in the middle, and both clean-cut only on the costa; sometimes suffused with 

 dull gray. 20-25 mm. (Caececia). 



July. Larva a general feeder. 



This species is superficially an Archips, but the palpi are markedly beaklike, 

 and the costal fold is completely absent. 



Maine to Manitoba. New York: Peru, Newcomb.
