it undergoes its transformations witliin the twig, or enters tlie 

 ground to pass the pupa state. 



Remedies. — Tliere seems to be none other than to catch and 

 kill this mischief-maker. In common with almost all other 

 curculios, this beetle has the habit of falling to the ground 

 when alarmed, and hence may be captured by jarring the 

 trees in the manner directed for the plum curculio, No. 94. 



ATTACKING THE LEAVES. 



No. 101. — The Peach-tree Leaf-roller. 



Ptycholoma persicana (Fitch ) . 



Early in spring, when the young leaves are expanding, a 

 small worm sometimes attacks them, and, drawing them to- 

 gether with fine silken threads, secretes itself within, and 

 feeds upon them. This larva is rather slender, of a pale- 

 green color, with a pale, dull-yellowish head, and a whitish 

 streak along each side of its back. When full grown, it 

 changes to a chrysalis within its nest, where it remains about 

 two weeks, and then escapes as a moth. 



The fore wings of the moth are of a reddish-yellow color, 

 varied with black ; at the base they are paler ; there is a large, 

 white, triangular spot on the middle of the outer margin, and 

 a transverse streak of the same hue within the hind margin. 

 This latter is divided by the veins crossing it into about four 

 spots, and is bordered on its anterior side by a curved black 

 band. When its wings are spread, this moth measures nearly 

 three-quarters of an inch across. It has never yet been re- 

 ported as very destructive anywhere, and is scarcely likely to 

 require the application of any special remedy. 



No. 102. — The Blue-spangled Peach-tree Caterpillar. 



Callimorpha Lecontei Boisd., var. fulvicosta Clem. 



Very early in spring there may sometimes be found shel- 

 tered under the loose bark of peach-trees, and sometimes also
