186 THE CANADIAN ENTOMOLOGIST. 



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 Trypanisma. The neuration of Agnippe 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 ? difficilisclla, ante v. 4, p. 

 192, belongs to the same group, near to if not in Trypanisma. 



E. prunifoliella. N. 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, with a 

 wide white streak from the mouth over the head, thorax and wings to the 

 dorsal ciliae. Al. ex. 3/% 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 Lithocolletis cratcegella Clem., but I have never 

 succeeded in rearing the insect from it, and possibly it may be made by 

 this species in its younger stages. 



eidothoa, gen. 110V. 



The insect upon which I found this genus resembles Evippe pruni- 

 foliella so closely that I have hesitated much as to the propriety of 

 separating them generically. The differences most marked are in the
