* PEACH. LEAVES. 



It closely resembles the foregoing, but has three white or pale 

 yellow stripes when young, and five when mature, and is also 

 then freckled with pale dots. See No. 40. 



The Unstable drab moth, occurs also upon the peach, at the 

 same time with the preceding, and most closely resembles it as 

 already stated. See No. 41. 



63. Peach Aphis, j^phis Persical Sulzer. (Homoptera. Aphidse.) 



This begins to appear upon the first small leaves which protrude 

 from the buds and continues through the season unless swept away, 

 as it frequently is, with surprising suddenness, by its several insect 

 enemies. (See Transactions, 1854, pp. 767-806, where a full 

 account of our American destroyers of the Aphides will be 

 found.) It punctures the leaves to suck their juices and is a 

 common though probably not the only cause of " the curl." It 

 lives together in crowds, hid in the crevices of the curled, cor- 

 rugated leaves, most of the individuals being larvae and wingless 

 females. The winged individuals are 0.12 long, black with the 

 under side of the abdomen dull green, the shanks and bases of 

 the thighs pale brownish, and the horns or horny tubes as long as 

 to tlie tip of the abdomen. This would appear to be different from 

 the Eur<jpean peach aphis as figured in Koch's invalual)le mono- 

 graph and described by Fonscolombe and others, though the wing 

 veins coincide with Walker's description. I however have not 

 yet given this insect a careful examination, and have noticed indi- 

 viduals so unlike those above described that they seemed to be 

 another species. 



The Buffalo tree-hopper, a light green jumping insect shaped 

 like a beech nut, puncturing and sucking tlie juices. See No. 22. 



The Saddled leaf-hopper, a smallish oblong black jumping 

 insect witli a hirge briglit yellow spot like a saddle U2)on the mid- 

 dle of its back. See No. 69. 



affecting the fruit. 



Tlie Plum weevil (No. 70) bores in the young fruit, causing it 

 to drop from tlie tree. The Rose bug (No. 50") sometimes invades 

 this fruit also, nibbling and killing it.
