reddish-brown." This description of the larva suits the larvae of a great 

 many species. 



O. prunivorella. N. sp. 



Dark steel gray, almost brown. Labial palpi white, each joint tipped 

 externally with dark steel gray. Antennae of the general hue, faintly 

 annulate with whitish. Thorax and primaries dark steel gray, the primaries 

 with about nine faint whitish costal streaks, the first near the base and the 

 last at the apex, becoming gradually longer from the base to the apex, all 

 faintly dark margined internally, the last three or four nearly perpendicular 

 to the costal margin, crossing the wing and Uniting near the dorsal margin, 

 where they are very narrow and indistinct. A small black apical spot, 

 behind which are three dark hinder marginal lines in the ciliae, the first 

 of which is at their base, and becomes furcate in the dorsal ciliae, the 

 second is at the middle, and the third at the apex of the ciliae. Al ex., 

 yi inch. Kentucky. 



The larva mines the leaves of Apple trees (Mains) and Wild Cherry 

 trees (Primus serotina), making a large tentiform mine on the under 

 surface, which can only be distinguished from that of Lithocolletis crataegella 

 Clem., in the same leaves, by its larger size. It is at first a short crooked 

 line, which ends in the large tentiform mine. It leaves the mine to pupate 

 under the edge of the leaf turned down. 



Lithocolletis crataegella, Tischeria malifoliella, Aspadisca splendor if erella, 

 and so many larvae of larger moths feed indifferently on the leaves of 

 Crataegus, Primus and Mains, that I at first, when I bred this insect from 

 Apple and Wild Cherry leaves, was inclined to suppose it to be O. 

 cralaegifoliella Clem., but a slight inspection shows it to be different, and 

 I have never found it feeding on Haw leaves. Among other things which 

 distinguish it from O. crataegifoliclla and O. inusitatumella the posterior 

 margin of the wings is not whitish, and it has three hinder marginal lines 

 in the ciliae. It may be found in all stages through the summer and fall. 



Personal. — We are pleased to learn that Mr. Aug. R. Grote, one of 

 our esteemed contributors, well known for his many valuable papers on 

 Lepidoptera, has removed from Demopolis, Alabama, to Buffalo, N. Y., 

 where he has undertaken active work in connection with the Society of 

 Natural Science.
