136 WILLIAM T. M. FORBES 



New Hampshire; Pennsylvania; New Jersey; Kentucky. 



9. D. macula tella Dietz. Head bright ochre yellow; antcnnse three-quarters as 

 long as fore wing, fuscous above, and silvery below; thorax powdery; tegulse dark 

 brown anteriorly. Fore wing dull, powdery gray, tinted with yellow, with irregu- 

 lar dark costal spots and broken fasciae; tufts small, R 4 and R 6 stalked. 10-12 mm. 



I have never seen this form. 

 Pennsylvania; California. 



10. D. tricingulatella Clemens. Head blackish; face whitish. Antennae grayish; 

 palpi gray on outer side. Fore wings over six times as long as wide, gray, slightly 

 dusted with fuscous; a dark spot at base of costa; a band a third way out, hardly 

 reaching inner margin; a broad, irregular, brassy-brown band in middle of wing, 

 besides some brassy areas nearer base, and other irregular dark bands outwardly. 

 Fringe checkered black and white, pale outwardly. 10 mm. 



This species and the next are easily recognized by their pattern, which is formed 

 of grayish white, blackish, and golden in about equal proportions. 

 Northern New Jersey and Pennsylvania. 



11. D. miscecristatella Chambers. Differs from D. tricingulatella only as noted 

 in the key. Fore wing only five times as long as wide; yellow spots normally less 

 developed (fuscocristateUa Chambers). 



Var. auricristatella Chambers is pale, with the head wholly whitish. 

 I have taken the moth in July. 

 Kentvicky; Worcester, Massachusetts. 



12. D. ornatella Dietz. Face yellowish white; vertex and thorax dark brown; 

 antenna; silver gray. Fore wing dark brown with irregular, silvery and golden 

 patches and oblique bars; with raised, brown tufts. Hind wing more gray. 6.5 mm. 



This is said to be the smallest Tineid with folded maxillary palpi. It occurs 

 in July. 



District of Columbia. 



13. D. auriferella Dietz. Similar, the golden and silvery markings on the fore 

 wing less distinct. 8 mm. 



District of Columbia. 



14. D. marginimaculella Chambers. Fuscous ash-gray; head lighter, dull clay 

 color; antennae gray. Fore wing neatly and regularly spotted with black; rough 

 looking, without any yellow or golden scales. Costa heavily black-marked at base, 

 with foiir large, black bars toward the middle and three small ones toward apex. 

 Fold with dark spots at middle and four-fifths way out, a dorsal spot toward apex, 

 and spots a quarter, half, and three-fourths way out on the cell, the latter, and 

 the outer one in the fold, larger. Hind wing gray. 10 mm. (maculimarginella 

 Chambers; Tinea Chambers). 



I have seen the type and believe it belongs in Diachorisia. It is certainly no 

 Tinea. It came from Kentucky. 



15. D. (?) heteropalpella Dietz. Silvery white, reticulate with golden brown; 

 with more or less alternating, dark costal and dorsal spots. Head whitish, mixed 

 with brown on vertex; thorax white; front of tegular brown. Maxillary palpi long, 

 folded, the first joint as long as the remainder. Eyes small, round; antennae three- 

 fourths as long as fore wings, with whorls of loose scales like Tinea; fore wing 

 apparently with R 5 and Mj stalked; hind wing narrow, costa sinuate. 8 mm. 



This species may belong to the Adelidae (subgenus Bathroxena Meyrick; Pelates 

 Dietz, preoccupied ) . 



Plummer's Island, Maryland. 



16. D. (?) afflictella Walker is a plain blackish species, 25 mm. in expanse, which 

 very likely does not belong here (Tinea Walker).
