Acrobasis nigrosignella Hulst. 



I have a single specimen that I refer to this species, Tryon, 

 N. C, May 7, 1904 (W. F. Fiske). Ragonot refers the name 

 as a synonym to his minimella (Mon. Phyc. Gall., i, p. 105, 

 1893), but I can not concur in this view. Minimella Ragonot 

 should rightly have no standing, being described from a 

 female only, and from its size, markings, and locality I refer 

 it to nebulella Riley (see below). 



Acrobasis eliella, n. sp. 



Head and thorax gray, with a reddish shade; abdomen gray, the seg- 

 ments ringed with whitish. Fore wing gray, shaded with red at the 

 base, the scale-ridge black, extending half way across the wing, resting 

 on inner margin ; beyond it a broad orange-red band, narrowing toward 

 costa and followed by a black shade on the costal half; discal dots 

 joined; outer line mesially exserted, slender, denticulate, with an 

 oblique inward shade from its upper angle, followed by a red shade. 

 Hind wing gray. In the male there is a broad black streak on the 

 hind wings below from base to beyond middle, approaching the costa at 

 its end. Expanse, 19 mm. 



Four males and six females East River, Conn, August 20, 

 1906 (Chas. R. Ely). 



Type. No. 11547, U. S. National Museum; three speci- 

 mens in Mr. Ely's collection. Named in honor of Mr. Charles 

 R. Ely. 



Acrobasis stigmella, n. sp. 



Head yellowish white on face and vertex, the palpi tipped with white; 

 collar white in the middle, the rest of the thorax dark purplish gray; 

 abdomen yellowish gray, ringed with dark at the bases of the segments, 

 the basal segments brown dorsally. Wings purplish gray, the basal 

 space very dark, the scale ridge scarcely darker, followed by a narrow 

 obscure reddish shade; discal dots small, separated; outer line whitish, 

 not strongly relieved, excurved in the middle, dentate, surrounded by a 

 darker purplish shading. Hind wings pale gray with a yellowish tint. 

 In the male there is a black subcostal streak on the fore wings below 

 and an elongate oval patch close to the costa of hind wing below before 

 the middle. Expanse, 19 mm. 



Two males, one female, bred from larvae on hickory, Fort 

 Lee, N. J., May, 1896 (H. G. Dyar) ; one female, East River, 

 Conn., August 20, 1906 (Chas. R. Ely). 



Type. No. 11548, U. S. National Museum.
