mont County, Ohio. The mine resembles that of L. amphi- 

 carpeifoUella Clem, very closely and contains from one to 

 eight larvae. It may occupy almost the entire surface of the 

 leaf, with finger-like projections made by the individual lar- 

 vae. The cocoon, as in the other species of the genus, is spun 

 outside the mine. Mines of the first generation may be col- 

 lected toward the end of June, those of the second generation 

 in September. Although the mines are common where the 

 food plant occurs, the species is a difficult one to rear, as a 

 large proportion of the larvae are parasitized. 



Imagoes, July 8th to 29th. 



The differences between this species and L. amphicarpei- 

 foliella Clem., though slight, are constant. These differences 

 are italicized in the description. 



Type and paratypes in my collection. 



Acrocercops strigosa n. sp. 



Head brownish with whitish scales intermixed. Palpi fuscous. 

 The labial palpi have the base of the terminal joint and a ring near 

 the base whitish. Antennae fuscous. 



Fore wings pale brownish with a sprinkling of fuscous scales, which 

 are occasionally gathered into spots on the margins and near the tip 

 of the wing. A series of seven oblique almost parallel and equally 

 distant narrow white lines cross the wing from costa to dorsum, 

 reaching the dorsum farther from the base. The first of these is 

 placed at the basal fifth on the costa; the third forks below the fold; 

 the fourth and fifth are a little interrupted in the middle; the seventh 

 is concave outwardly. There is a short white streak at the extreme 

 apex, and a similar one beyond it crossing the cilia. Cilia gray. Hind 

 wings and cilia brownish gray. 



Legs whitish gray, with broad black annulations. Abdomen gray. 



Expanse: 10 mm. (male). 



Powell County, Kentucky; one specimen bred on Quercus 

 prinus L. The early mine is a narrow white gallery, which 

 suddenly expands into a very large whitish blotch. The larva 

 feeds here and there, finally consuming the entire parenchyma. 

 A dense brownish cocoon, ornamented with several whitish 

 globules, is spun in a fold in a leaf. Mine collected May 23rd ; 

 imago, June 25th.
