236 WILLIAM T. M. FORBES 



wings beyond middle, or a patch in fold, which is rarely obscure. Fore tibia solid 

 brown, or with a complete, broad, longitudinal stripe. 12-15 mm. 



Larva on oak and chestnut in September; pale yellowish or greenish; head and 

 entire thorax black. Moth in March and April; and in July. 



Generally distributed. New York: New Windsor (Morton). 



2. P. obsoletella Zeller. Closely similar to P. quercicella, but usually, slightly 

 larger (16 mm.), and more evenly strigose; usually without the postmedial shade 

 across the wing. Larva also on oak and chestnut, but with only prothorax black ; 

 mesothorax with some red on sides, and metathorax pale, like the abdomen. 



Ohio. New York: Ithaca. 



P. dubitatella Zeller appears to be a synonym of P. obsoletella, but without 

 knowledge of the larva this must be a little uncertain. 



3. P. faginella Chambers. Mouse -gray, with the strigae less contrasting, deep 

 brown; the terminal line reduced to about four dots at apex, inconspicuous. 

 Longitudinal striping of antennae unusuallv long, obscure; white lines on palpi 

 very slender, broken. Fore tibia with a brown patch on anterior side. 13 mm. 

 (Hagno Chambers). 



Larva on beech; whitish with ferruginous head, some ferruginous on prothorax 

 and a pinkish patch on each side of mesothorax. 



4. P. cryptolechiella Chambers. Very similar to P. faginella,, rather evenly col- 

 ored, with slender, inconspicuous, broken terminal line and light fringe. Head, 

 thorax, and base of fore wing reddish orange. 15 mm. 



This species is unknown to me. It was bred from holly. In the United States 

 National Museum it is identified with a species from Vaccinium, known from 

 Massachusetts to North Carolina. 



5. P. reflexella Clemens. Fore wings dull straw color, strigose with fuscous, 

 appearing dull fuscous brown. Terminal dots obscure; fore tibia slightly dark- 

 ened. 20 mm. (quercicella Zeller, not Clemens; cressonella Chambers). 



Larva on oak. Moth in June. 



Massachusetts to Virginia. New York: Ithaca (determined by Chambers). 



6. P. ferruginosa Zeller. Ground color and fringe, light ochreous, markings as 

 in P. reflexella, with distinct black discal dot. Fore tibia light. 18 mm. (con- 

 fertella Walker). 



Maine to Ohio. New York: Otto. 



7. P. fletcherella Gibson. Antennae black, annulate with light ochreous; fore 

 wing pale golden yellow, rather heavily dusted with pale brown, with purplish 

 reflections; discal dot black, conspicuous; fringe ochreous, shaded with brown. 

 Legs bright pale ochreous; fore leg sometimes dark; tarsal joints dark. 19 mm. 



Larva on aspen poplar; yellowish green, head jet black, cervical shield blackish, 

 brown in middle, tubercles inconspicuous, a few blotches of crimson on eighth 

 segment of abdomen, above spiracles; anal plate black. 



Ottawa, Ontario. 



Members of the genus have also been bred from Ambrosia, Amelanchier, and 

 Carpinus, but not named. 



6. AGONOPTERYX Hiibner 

 (Depressaria,-\n part; Agnopteryx] 



Similar to Depressaria,, but with Cu^ and Cu 2 stalked in the fore wing (fig. 139); 

 hind wing less strongly lobed, as a rule. 



The imagoes of this genus and of Depressaria emerge in the fall, often as early 

 as August, and overwinter. They are otten found under bark or flying by day 

 in the early spring.
