Agonoptcrix pteleae (Barnes and Busck) McDunnoiigh, Check list of Lepid- 



optera of Canada and the United States of America (Part 2, Microlepidop- 



tera), No. 8426, 1939. 

 Depressaria pteleae (Barnes and Busck) Meyrick, in Wytsman, Genera insec- 



torum, fasc. ISO, p. 175, 1922. — Gaede, in Bryk, Lepidopterorum catalogus, 



pt. 92, p. 342, 1939. 



Labial palpus light ochreous ; second segment with fuscous base and 

 iiTorations exteriorly; third seginent with fuscous basal and sub- 

 apical annuli. Antenna fuscous. Head reddish ochreous above ; face 

 light silvery ochreous, Tliorax and fore wing light ochreous-brown 

 mottled and suffused with black and brown, the entire surface rough- 

 ened with raised scales ; extreme base at inner angle whitish ochreous 

 broadly edged with black; from costa to end of cell a large blackish- 

 fuscous blotch; along costa and around termen a series of blackish- 

 fuscous spots ; first and second discal spots black, the latter obscured 

 by the large costal blotch. Hind wing light ochreous fuscous; cilia 

 light ochreous brown with basal band a shade lighter. Legs light 

 ochreous brown suffused and annulated with blackish fuscous. Ab- 

 domen light ochreous-brown, with two lateral longitudinal rows of 

 black spots on the underside. 



Male genitalia. — Harpe moderately sclerotized, pointed, and almost 

 entirely clothed with fine hairs; at base, just inside costa, is a group 

 of long fine spines; clasper and a narrow "spur" of the sacculus adja- 

 cent to it, heavily sclerotized. The clasper tapers gently to a fine 

 point, is slightly curved, and reaches almost to costa. Anellus a 

 heavily sclerotized oval plate, longer than broad, with truncated pos- 

 terior edge ; lateral lobes large, hairy. Transtilla a narrow sclerotized 

 band with well-developed, hairy lateral lobes. Aedeagus rather stout, 

 curved, and pointed, with a lateral, lightly sclerotized flap from about 

 the middle to the apex. Gnathos a short oval knob armed with many 

 spines. Socii small, mainly indicated by hairs. Tegumen with a 

 single apical projection. 



Female genitalia. — Ostium large, near posterior edge of genital plate. 

 Genital plate greatly produced anteriorly and narrowly cleft on an- 

 terior margin. Extreme posterior portion of ductus bursae abruptly 

 constricted before ostium, where ductus seminalis enters ; ductus bursae 

 gently tapering to form the large bursae copulatrix. Signum a roughly 

 diamond shaped, sclerotized, spined plate. 



Alar expanse, 20-22 mm. 



Type. — In the United States National Museum. 



Type locality. — Decatur, 111. 



Food plant — Ptelea trifoliata L. (hoptree). 



Remarks. — This species is exceedingly close to pulvipennslla but dif- 

 fers from it by the rough-scaled fore wing, smaller anellus, and less 

 sharply pointed anterior margin of the genital plate.
