of an inch in diameter on the bark of the branches and twigs. 

 In confinement it will make its cocoon on leaves, but in nature 

 it is careful to deposit them on the branches, where it remains 

 through the winter. The larva completes the cocoon, at least 

 all that is visible, within the space of one hour. The upper side 

 overlaps the under side, leaving an open slit between the top 

 and bottom. The under side is quite free from the top, and is 

 oval elliptical. The moth was found in considerable abundance 

 resting on the under side of apple-leaves the 19th of June. 



Sometimes five or six larvae will mine a single leaf, thus de- 

 facing the tree. They have been abundant at Salem, and I 

 have seen their mines at Amherst. The habits of this genus are 

 not well known as yet so far as I am aware. This species is un- 

 described, and may bear the name of Micropteryz pomivorella. 

 It is closely allied to M. calthella of Europe, though not much 

 more than one-half as large. The fore wings are long ovate, 

 with a long silken fringe, while the hind wings are very narrow, 

 acute, and the fringe at the base of the wing half as long as the 

 wing itself; the body is very short and small, and the antennae 

 about one-half as long as the fore wings, and on the head is a 

 loose spreading tuft of uneven hairs. The body and wings are 

 of an uniform dark bronze hue with purple and metallic reflec- 

 tions ; the fringe is concolorous with the wings. On top of the 

 head is a conspicuous bushy tuft of bright reddish orange hairs. 

 The legs are of a leaden hue, the hairs yellowish, the hind 

 tibiae long and hairy, with four long, slender spurs ; the antennae 

 dark on the terminal three-fourths, pale orange at base. The 

 palpi are leaden gray, concolorous with the legs. The under 

 side of the wings are leaden gray. Length of the body .07, of 

 the body including folded wings, .10 of an inch. 



INSECTS INJUEING THE CHERRY. 



The V-marked Tortrix. — This is not an uncommon moth. 

 Mr. F. W. Putnam has raised it in abundance from the cherry, 

 and it has been detected at Portland, Maine, by Mr. E. S. Morse. 

 It enters our houses at night during July. Unfortunately noth- 

 ing is yet known of its early stages. It may be named Tortrix 

 V-signatana. 



The head and thorax are tawny, with paler scales on the 

 hinder edge of the thorax, concolorous with the broad tuft at
