Canada and Maine to Virginia and Kansas. New York: Ithaca, Rhinebeck. 



T. leuconotella Busck, a slightly paler species with a single conspicuous, not 

 ocellate, canary-yellow dot at the end of the cell, and a faint light brown costo- 

 apical spot, has been determined by Busck from East Aurora, Xew York. It was 

 described from Washington State. 



8. T. trinotella Busck. Antennae dark purple, palpi light ochreous, face ochreous, 

 thorax and fore wing brown, prominent ochreous dots at middle of wing, end of 

 cell, and in fold; a few ochreous scales at beginning of costal fringe. 15 mm. 



May. Caterpillar, apparently of this species, on (Enothera in Missouri. 

 Western Pennsylvania. 



9. T. levisella Fyles. Palpi fuscous with third segment paler. Fore wing 

 clouded brown, a little lighter than T. juncidella, with a darker postmedial band 

 tending to break into spots; and an obscure, pale brown, horse-shoe mark at end of 

 cell. 15-22 mm. 



June and August. Caterpillar folding and crumbling basal leaves of Aster 

 macrophylhis in June and eating the parenchyma. Pale green, with darker dorsal, 

 subdorsal, and lateral lines; head and cervical shield glossy black; mesothorax 

 brown in front, behind with four conspicuous white patches; tubercles, spiracles 

 and leg-plates black. Cocoon capsule-like, open at one end. 



Canada; New York. 



T. washingtoniella Busck, described from Ambrosia, artemisicefolia, and reported 

 from the District of Columbia to Missouri, appears to be the same species. 



10. T. chambersella Murtfeldt. Palpus nearly three times as long as head, sec- 

 ond segment smooth-scaled above. Outer margin more oblique than usual, nearly 

 straight. Fore wing clay-color dusted with light fuscous; head, thorax, and 

 palpi concolorous. Fore wing with dusting gathering in blackish streaks between 

 the veins; a blackish bar or streak in the cell beyond the middle, and a spot at 

 the end of- the cell sometimes also drawn out into a streak. Terminal line black, 

 continuous; fringe whitish at base. Hind wing pale gray with whitish fringe. 

 9-13 mm. (inasquepulvella Chambers). 



End of May to September (2 broods?). Caterpillar in a fusiform case, on 

 Ambrosia artemisicefolia, webbing together the divisions of the leaf, and eating 

 the upper parenchyma from the inside. Head polished, dark brown; cervical shield 

 small, yellowish; prothorax otherwise dark brown; rest of thorax and third and 

 fourth segments of abdomen brown-black with a white fold on the posterior edge 

 of each segment; first two segments of abdomen wholly black; the rest with an 

 oblique anterior lateral band on each segment. Caterpillar making several nests, 

 and pupating in the last one. 



Western Pennsylvania; Kentucky; Missouri; and south. 



11. T. inversella Zeller. Second segment of palpus with a large loose tuft on 

 upper side; dark gray on outer side; third segment very short, with a black ring 

 beyond middle. Fore wing shaded powdery gray, with a diffuse whitish post- 

 medial band, and a longitudinal shade through cell. Slightly diffuse black spots 

 beyond middle and at end of cell, and near base and middle of fold; costal edge 

 blackish at base. 18 mm. (Epicorthylis Zeller). 



Texas ( doubtful northward ) . There is a related but much smaller species 

 known from Maryland and Virginia in June. 



12. T. trimaculella Chambers. Palpus with third segment only half as long as 

 second. Pale yellowish, minutely and sparsely dusted with reddish ochreous; head 

 and palpi nearly white; third segment of palpus tinged with fuscous. Two small, 

 nearly round, blackish spots at middle of wing, obliquely placed in fold and cell, a 

 larger one at end of cell, and a minute terminal series. 12 mm. 



April and May. Almost identical with Dichomeris touceyellus, except for the 

 smoothish Trichotaphe palpus with short third joint. 

 District of Columbia to Texas.
