AMERICAN LEPIDOPTERA. 59 



T. oregonella Busck.— Dyar's List, p. 572, No. 6518. 



Bred in large numbers from a fungus by Mr. A Busck. Readily 

 recognized by its rusty white wings, with several, wide, dark brown 

 longitudinal streaks, of which one on the fold, reaching from base 

 to apical third of wing, and one in the middle of the wing, reaching 

 from basal third to apex are the most conspicuous; a less conspicu- 

 ous streak along basal third of both margins; some irregular spots 

 along costal margin, and a row of connected spots along base of 

 dorsal cilia. Cilia whitish, with brown dividing line about their 

 middle and some scattered brown scales. Hindwings grayish fus- 

 cous ; narrower than the forewings, costa emarginate beyond mid- 

 dle ; cilia gray, yellowish at base. 



Exp. 15.0-17.0 mm.; 0.6-0.8 inch. 



Hub. — Oregon. 



T. mtiltistriatella n. sp. — PI. II, fig. 5.- -Palpi yellowish white, lahials 

 externally, except at apex, dark brown. Hair of face whitish, rather appressed. 

 on the vertex sordid white, intermixed with brown in the middle. Antennae 

 moderately robust, scarcely one-half the wing length, brownish above, paler be- 

 neath, basal joint whitish. Thorax white and fuscous intermixed. Forewings 

 elongate, pointed, white, with dark brown marginal spots and numerous longitu- 

 dinal communicating lines, without lustre ; a large elongate spot about middle of 

 costa, before it several smaller spots, and beyond it about five spots, decreasing in 

 size; a row of dots along base of dorsal cilia, forming an almost uninterrupted 

 line, a distinct spot at beginning of dorsal cilia; the space between the longitu- 

 dinal lines is sparsely sprinkled with brown scales. Cilia ochreous brown, with 

 an indistinct dividing line about the middle, the basal half being more grayish, 

 the outer half more ochreous, with dark bars, corresponding to the marginal 

 spots. Hindwings under 1, costa emargiiiate in apical two-fifths, pointed, pale 

 grayish wiiite, speckled with fuscous scales; cilia concolorous, pale ochreous at 

 base. Abdomen ochreous fuscous above, reddish ochreous brown beneath. Legs 

 ochreous white, dusted with fuscous, especially anterior and middle pair; tarsal 

 joints paler at apex. 



Exp. 16.0-17.5 mm.; 0.64-0.7 inch. 



Hub. — Canada (Toronto); Maryland (Plummers Island). 



Specimens in my collection were bred from a fungus, growing on 

 beech stumps. A specimen from the second locality was taken by 

 Mr. A. Busck in May, 1903. A specimen in poor condition, collec- 

 ted by Chambers, labeled "Tinea sp.," but without locality, is in the 

 Cambridge Musuem. Very closely related to oregonella. 



T. rileyi n. sp. — Maxillary palpi grayish white; labial palpi dark fuscous 

 externally, sordid white, dusted with fuscous within. Head and thorax dark 

 brown, patagia speckled with white. Anteniue pale ochreous fuscous. Fore-
