respects the structure of the two insects is identical, except that while the | 
forewings of that species are very long and narrow, and almost pointed, 
in this their width af the apex ts more than one-fourth of their length, with 
the costo-apical' angle rather sharply, and the dorso-apical very obtusely 
rounded, and the apex oblique and a little concave. Yet the neuration does 
not differ. There is a similar difference in the shape of the hind wings, 
but none in the neuration. But for the palpi, it would, in external 
appearance, resemble a Zortrax. 
5. YŸ. caryæfoliella. NN. sp. 
Tongue yellowish, except at the base, where it is brownish. Palpi 
dark purplish-brown, except the inner surface, which is pale yellowish, and 
the apex of the tuft, which is dusky grey. Head, antennae and thorax 
reddish-golden, suffused with fuscous, in some lights appearing dark 
golden, in others reddish-brown. Antennae with pale annulations. 
Anterior wings with a silky lustre, dark yellowish-red suffused with fuscous, 
shining, some portions of the wing appearing almost slate color, whilst 
others are dark purplish-red, changing with the light ; two or three minute 
blackish dots upon the disc ; posterior wings plumbeous. Legs brown 
upon their anterior, yellowish on their interior surfaces. Alar ex. 1% inch.

The structure of this insect is identical with that of the preceding 
(Y. querciella), except that the anterior wings are scarcely so wide in 
proportion to their length. It resembles it closely, but may be dis- 
tinguished by the slightly narrower wings, which have a little wider 
expanse and have more of a deep dull red, and are not of so PERS a 
brick red. 
The larva sews together the leaves of Hickory trees (Caryæ alba.) 
When taken (June 6th) it was about 34 of an inch long, green, with six 
narrow, and some of them interrupted, white stripes which did not quite 
reach the anal segment ; head ferruginous ; the following segment brown ; 
true feet black. The next day it became white suffused with pink, and 
the longitudinal stripes became deep pink. On the roth it became a 
pupa, and on the 23rd the imago emerged. 
I should regard this as a variety of ”. guerciella but for the decided 
differences in the larva. |

Tongue and second joint of palpi brown, faintly tinged with Cole 
third joint and apex of the second, pale straw colour. Antennae pale.
