Gracillaria, and the pattern and shades of coloration approach those of 
G. salicifoliella. It is, however, nearer to Agnippe, ante v. 4, p. 194, than 
to 7rypanisma. The neuration of Agrippe is incorrectly given at v. 4, p. 
194. That of the primaries is identical with that of this species, except 
that it lacks the first subcostal branch of this species ; and that of the 
secondaries is identical with this species. I do not feel certain that I am 
right in separating them generically. Gelechia? difficilisella, ante v. 4, p. 
192, belongs to the same group, near to if not in 7rypanzsma. 
Æ. prunifoliella. NN. sp. 
Labial palpi silvery white, except the base, which is dusky, and the 
tip, which is dark gray brown. Head silvery white. Antennae dark 
grayish brown. Thorax dark grayish brown on each side above the wings 
with a broad median longitudinal white streak from the base to the apex 
and continued thence along the posterior margin of the primaries to the 
cilia. Primaries (except the posterior margin as just stated) dark grayish 
brown, the line between the two colors scalloped, or rather the white 
portion sends two or three teeth or processes into the brownish part, one 
of which is just before the ciliae and is opposite to a costal white streak ; 
dorsal ciliae dusky silvery dusted with dark brown. Secondaries pale 
yellowish fuscous. 
When the insect is in repose it appears to be dark gray brown, witha 
wide white streak from the mouth over the head, thorax and wings to the 
dorsal ciliae. AZ ex. 38 inch. Kentucky. 
I do not know whether the larva is at any time a miner or not. It 
feeds upon the leaves of the Red Wild Plum (Prunus Americana), where 
I have found it in September feeding under the tip of the leaf turned 
downwards. The larva is pale green, immaculate. I have frequently 
found on the under side of the same leaves a tentiform mine which I 
suspected to be that of Zifhocolletis crategella Clem., but I have never 
succeeded in rearing the insect from it, and Aosszb/y it may be made by 
this species in its younger stages.

The insect upon which I found this genus resembles Luippe prunt- 
foliella so closely that I have hesitated much as to the propriety of 
separating them generically. ‘The differences most marked are in the
