368 ANNUAL REPORT OF NEW-YORK 



CHERRY. LIMBS. 



female makes in the limbs to deposit her eggs. With us it appears 

 to resort to the maple more than any other tree, and in forests and 

 frequently in the trees around our dwellings the loud shrill note 

 of the male is heard every clear sunshiny day throughout dog- 

 days. See Harris's Treatise, p. 190. 



T-l. Cherry bark-louse, Lecanium Cerasifex, new species. (Homoptera. 

 CoGcidae.) 



In June, adhering to the bark upon the under side of the limbs 

 of the wild black cherry, a hemispherical shell nearly the size 

 and shape of a half pea, of a black color more or less mottled 

 with pale dull yellow dots, covering a mass of minute eggs the 

 lice from which spread over the bark and subsist upon its juices. 

 I find no bark-louse indicated by authors as occurring upon the 

 cherry in Europe. We in this country have two insects of this 

 family infesting trees of this kind, the one now mentioned and the 

 following. 



75. Cherry scale insect, j^spidiotus Cerasi, new species. (Homoptera. 



Coccidae.) 



In winter, on the bark of the choke cherry, little roundish 

 white wax-like blisters, scarcely perceptible to the naked eye, 

 containing beneath them in an open cavity a cluster of minute 

 dull red or resin-like eggs. The history and habits of this species 

 will be analogous to that of the Apple bark-louse, No. 15. 



AFFECTING THE LEAVES. 

 70. May beetle, Zac/mosferna/usca, Frohlich. (Coleoptera.Melolonthidae.) 



About the middle of May gathering by night upon the trees and 

 eating the leaves, sometimes in such numbers as to wholly strip 

 the foliage from the choicer varieties; a thick-bodied chestnut- 

 brown or black beetle nearly an inch long, its legs of a lighter 

 tawny yellow color and its breast coated with pale yellowish hairs. 



The larva of this insect lives under ground and is most inju- 

 rious to meadows and pastures. It has been very destructive the 

 present year in some parts of our State, and enquiries have been 

 addressed to me for information respecting it and the best remedies
