242 Teneina of the United States. 



recurved, divergent, over arching the vertex, simple ; the third joint 

 more than half as long as the second, and accuminate similar to those 

 of many species of Gelechia. Wings broad; with rather short 

 short cilice. The forewings in outline and neuration nearly those of 

 Strobisia iridipenella, Clem,, widest about the middle and with the 

 apex obtusely rounded ; the costal vein runs near the subcostal for 

 about half its length and then rather suddenly diverges, attaining the 

 margin about the middle ; the subcostal subdivides into five nearly 

 equidistant branches of which the first arises before the middle and 

 the last attains the apex ; the median subdivides about the end of 

 the cell iuto three equi-distant branches of which the first arises op- 

 posite to the third subcostal branch, and the last is parallel to the 

 apical branch of the subcostal, and is produced forward for a short 

 distance into the cell which is closed ; there is no discal branch ; fold 

 very distinct, sub median vein furcate at its base. Hind wings Avider 

 than the forewings, width equal to half of their length, in form and 

 neuration like those of Tortrix ; the costal margin is slightly excised 

 from the base to the apical fourth, and the dorsal margin is very faint- 

 ly excised beneath the rounded tip. The costal vein is long, the cell 

 is closed, short and wide, and near the subcostal vein the discal is 

 strongly angulated towards the base. The subcostal and median are 

 both furcate behind the cell, the superior branch of the subcostal 

 going to the apex ; the median emits a branch before the end of the 

 ceil ; the fold, submedian and internal veins are all distinct. (Perhaps 

 it would be more correct to say that the median is straight and with 

 out branches, and that the discal is strongly angulated anteriorly near 

 to the subcostal vein and still more angulated posteriorly near the 

 median with a branch from the latter angle which bifurcates behind 

 the cell). The wings are but slightly deflexed in repose, and the in- 

 sect sits flat upon the surface of the object on which it rests. 



H. coryliella, n. sp. 



Shining black with a velvety lustre ; the base and under surface 

 of the palpi, face, anterior surface of the basal joints of the legs, and 

 under surface of the abdomen are white ; there is a transverse white 

 spot on the discal vein of the forewings which is visible also on the 

 under surface ; sometimes it is faint and interrupted ; and there is 

 a white streak across the middle of the apical cilise, and sometimes 

 the entire apical half of the cilia is white. AntennjB fuscus, hind 

 wings shining fuscus. Al. ex. f inch. 



The larva is white and feeds on the under surface of leaves of the 

 filbert (Corylus Americana), under a thin ■ silken web which is rather
