PEACH. LEAVES. 
issues a minute cylindrical bark-beetle of a dark brown color, its 
wing covers with deeply impressed punctured furrows and short 
hairs and its thorax also punctured. Length 0.10 or less. I 
have obtained this from elm bark, the same situation in which Dr. 
Harris found it, and this is doubtless its original residence. Hut 
Miss Margaretta H. Morris has met with it under the bark of 
peach trees which were affected with “ the yellows.” See Down¬ 
ing’s Horticulturist, vol. ii, p. 502. 
The Peach-tree borer above described (No. 57) is not confined 
to the root, but frequently occurs also under the bark of the 
trunk, particularly in the forks of the limbs, causing the gum to 
exude from the spot where it nestles. 
The Oak pruner, or a species possessing the same habits, bores 
in the heart of the small limbs, the latter- part of summer, a few 
inches or a foot or more in length, and then girdles the limb, 
severing the wood as smoothly as though it were cut off bv a saw

61 . Peacii bark-louse, Lecanium Pcrsica, Modeer. (Homoptcra. Coccid;e.) 
Fixed to the smooth bark, commonly beside a bud on the origin 
of a twig, a blackish hemispherical shell the size and shape of a 
half pea, its surface uneven, shining, commonly showing a pale 
margin and stripe upon the middle; covering a multitude oi 
minute eggs which hatch small lice like mites, which scatter 
themselves over the bark, puncturing it and sucking its juices, 
similar to the pear bark-louse No. 51.

62 . Peach Tortrix, Orcesia Persicana, now species. (Lepidop. Tortricidie.) 
Early in May when the young leaves are putting forth from 
their buds, a worm tieing them together with fine silken threads, 
secreting itself within and feeding upon them; the worm rather 
slender, pale green with a whitish streak along each side of its 
hack and a pale dull yellowish head; changing in its nest to a 
pupa about the middle of June and giving out the winged moth 
the beginning of July. The moth with the fore wings rusty yel-
