THE CANADIAN ENTOMOLOGIST. 127 



the leaf around it also becomes stained of that hue. The larva is bright 

 green. Possibly this may be the N. bifasciella Clem., but I can discern 

 no trace of green in the wings. Dr. Clemens gives no measurements and 

 was not acquainted with the mine of bifasciella. He mentions, Proc. Ent 

 Soc. Phila.. Nov., 1S61, an empty mine in the leaves of the Wild Cherry 

 as doubtfully that of a Nepticula, and possibly dipterous,- and calls it N. I 

 prunifoliella. As, however, he says that that mine begins in a blotch, 

 and as he was not acquainted with the insect in any of its stages, and it 

 often happens that two or three species mine leaves of the same plant, I 

 have not deemed it expedient to adopt his name. The practice of naming 

 species from an empty mine or even a larva, is a bad one, I think. 



N. apici-albella. X. sp. 



Palpi and eye-caps white ; face reddish orange ; antennae silvery, 

 suffused with fuscous ; thorax and primaries dark brown, slightly irides- 

 cent, suffused with purplish or golden, according to the light : just behind 

 the middle of the wing is an oblique white fascia, which is nearest to the 

 apex on the dorsal margin ; ciliae of the general hue, except at the extreme 

 apex, which is white. Al. ex. A inch. Kentucky. Larva unknown. 

 Imago in June. 



X. minimeUa. X. sp. 



Palpi white : face ochreous ; eye-caps white : antennae light fuscous; 

 primaries fuscous to the fascia, which is just immediately behind the 

 middle, and is convex both anteriorly and posteriorly ; purplish fuscous 

 behind the fascia ; apex whitish. Al. ex. less than two lines. Kentucky. 

 At light in August. 



N. thorace-albella. X.sp. 



Palpi and eye-caps white  face reddish ochreous ; antennae pale fus- 

 cous ; thorax white, with a few scattered dark brown scales ; primaries 

 dark brown, with a curved white fascia about the middle, concave towards 

 the base, and rather indistinct upon the costa. A white spot at the 

 beginning of the costal ciliae, and an opposite dorsal one ; ciliae of the 

 general hue, except at the apex, where they are white. Al. ex. A inch. 

 Captured in June in Kentucky. 



A r . querci-castanella. N. sp. 



Head, eye caps and palpi white, except a dark brown spot between
