gray along dorsal edge. Hindwing blackish brown, cilia dark gray. 

 Abdomen gray, anal segment white. Legs white with brown shadings, 

 and brown annulations on tarsal joint. 



Expanse, 8-8.5 mm. 



Hab. — Pittsburgh, Pa., May 14-27, August II, October 5 

 (Engel), Oak Station, Pa. (Marloff). 



Type No. 10,287, U. S. National Museum. Cotypes in Mer- 

 rick Museum, New Brighton, Pa. 



This species is near Gracilaria lespedezaefoliella Clem., but 

 the larger size, bolder ornamentation, and the comparatively 

 long basal streak separate it from that species. 



Tinagma crenulellum n. sp. 



Antennae gray, annulated with ocherous. Labial palpi and head whitish 

 gray. Forewing ocherous strongly dusted with white, giving a speckled 

 appearance to the wing. A broad dark ocherous fascia on the middle 

 of the .wing of equal width on costal and dorsal edge. This fascia 

 is poorly defined basaly, but distinctly edged with white outwardly. 

 A pale gray shade crosses the wing beyond this central fascia extend- 

 ing nearly to the apex. Apical part of wing dusted ocherous, cilia 

 coarsely speckled with dark brown and white. Hind wings ocherous, 

 cilia smoky gray. Abdomen ocherous. Legs grayish. 



Expanse, 8.5-9.5 mm. 



Hab. — Pittsburgh, Pa., May 27-31, 1906, (Engel), New 

 Hampshire. 



The latter record was reported by Mr. Busck who received 

 this species from New Hampshire since he had my material for 

 study. 



Type in the U. S. Nat'l. Museum. Cotypes in the Merrick 

 Museum, New Brighton, Pa. This species is very close to, if 

 distinct from, the European Tinagma perdiccllum Zeller It 

 seems advisable to keep it under a separate name until the iden- 

 tity shall eventually be proven by the breeding of both species. 

 The American species has the labial palpi and head whitish, not 

 ocherous, as in the European species, and the central fascia of 

 the forewing has a different angle, more perpendicular not in- 

 wardly inclined on dorsal edge as in pcrdicellum. These dif- 

 ferences alone would hardly justify the separation of the 

 American form, but it is easier to prove the two forms syno- 

 nyms than to disprove the faulty record of the European 

 species here.
