with black specks, then becomiug a pale, whitish, somewhat silvery band, crosses 

 the wing. A broad median, dark, olive-green patch; the outer scales raised and 

 dotted with black. Beyond this patch are three light, squarish, costal spots. An 

 oblique, olive-green line passes from the outer margin just above the internal margin 

 to the costa, becoming nearly obsolete before reaching the costa, but ending on the 

 fourth costal spot. An apical dijsky spot. Hind wings dark slate, and fore-wings 

 beneath dark slate, with lighter costal spots. Expanse of wings, 15™°*. 



77. Cacosda semiferana (Walker). 



This leaf- roller is said by Miss Murtfeldt to occur on "various species 

 of oak, and a strougly marked variety on hickory." (Fernald's Cata- 

 logue of Tortricidfe, p. 12.)

Gelechia carycevorella Pack. 



Order Lepidoptera ; family Tineid.^:. 



Although we have numerous species of this extensive genus of Tiueid 

 moths feeding upon our forest trees, none, we believe, have been re- 

 corded as living at the expense of the hickory. 



The larvsB of the present species were found at Providence, E.I., feed- 

 ing upon the young, freshly unfolded leaves of the white-heart hickory 

 {Garya tometitosa), rolling them up. Within the roll the chrysalis was 

 discovered from June 2 to 4. The insect remains about two weeks in 

 this stage, the moths appearing in my breeding box June 17 and 23. 



The moth belongs to that section of the genus with moderately wide 

 fore-wings, which are oblong, and moderately pointed at the tip. Pro- 

 fessor Fernald informs me that it is allied to Gelechia bicostomaculellaof 

 Chambers. 



Moth.—Falvi very long, the third joint slender, one-half as long as the second; 

 second joint with black specks ; third black, but white at the tip. The fore- wings 

 broad, oblong. Head, thorax, and wings blackish, with whitish buff-yellow specks 

 aud dots. The fore-wings are dark pepper and salt, with a row of five deep black 

 spots along the middle of the wing, increasing in size towards the end of the wing; 

 the basal spot minute; the third large, and sending a branch obliquely inwards to 

 the costa; the fourth patch large, irregularly squarish ; above it is a black square 

 ■costal spot, next to a buff-white, distinct costal spot opposite another on the inner
