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. But 

 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. 

 See insects of Oak limbs. 



61. Peach BARK-LOUSE, Lecanium Persica., Modeer. (Homoptera. Coccidse. ) 



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 siu-face 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. 



AFFECTING THE LEAVES. 



62. Peach ToRTRiXjCrtEsiaPerst'cana, new species. (Lepidop. Tortricidio.) 



Eai'ly in May when the young leaves are i)utting forth from 

 their buds, a worm tieing them together with line silken threads, 

 secreting itself within and feeding upon them; the worm rather 

 slender, pale green witli a wliitish streak along each side of its 

 back and a pale dull yellowisli liead; cliaiiging in its nest to a 

 pupa about the niifUHe of June and giving out the winged moth 

 the beginning of July. Tlir moth witli the fore wings rusty yel-
