ENTOMOLOGICAL PAPERS OF DR. FITCH, 317 



This species is an exception to the ordinary generation of aphides, 

 in that it deposits no egg in the autumn, but hibernates beneatli the 

 snow. No eggs have been observed, nor males — it apparently pro- 

 diices young indefinitely. The winged forms produce two young in a 

 night — the wingless, four : these last bring forth young in three days. 

 Various insects that prey upon them are noticed. 



[The above (except the assembling and change of color) is additional 

 to the account given in 6th-9th Repts. Insects N. Y., pp. 91-98.] 



Remarks upon the Wheat-midge and other insects were made in a 

 general discussion following the essay. 



1863. Locust-Tree Borer. (Transactions N. Y. State Agricultural 

 Society, for 1862, xxii, 1863, p. 88.) 



Notices the occasional attack of the Clytus robinice [Ct/Uene 7'obinue] 

 upon the honey-locust, OleditseJiut triacanthus^ as well as upon the com- 

 mon locust ; also, Ctenuclia Latreillana [C. Virginica Charp.] as a 

 rare species. 



1863. The May-Beetle. Worm on Grape-Vines. (The Country 

 Gentleman, for June 18, 1863, xxi, ]). 399 — 13 cm.) 



Identification of the May-beetle, Lachnosterna fusca, &s injuring 

 cherry-trees, after dark, at Bailey's Cross Roads, Va., occasionally 

 stripping them, and also plum-trees, of all their leaves. Shaking upon 

 sheets, killing with boiling water, and feeding to swine or poultry, 

 recommended as the best remedies. 



Spilosoma Virginica identified, as feeding on the young tender leaves 

 at the extremity of the shoots of grape-vines, in West Haven, Conn. 

 The insect is briefly described, and hand-picking recommended as the 

 best remedy for it. 



1863. A Grape-Vine Beetle and Eose Bug. (The Country Gentle- 



man, for July 23, 1863, xxii, p. 65 — 20 cm.) 



The Grape-vine flea-beetle, Haltica clialybea 111. \_Graptodera chaly- 

 iea\, attacks the eye or bud when it first begins to swell, in Cumber- 

 land, Md. It had been very abundant and injurious in the same man- 

 ner, in different parts of New York, the past and present year. 



The Rose-bug attacked the grai:)e blossoms and continued to destroy 

 the grapes until about half-grown. In Saratoga county they had de- 

 stroyed the young plants of Indian corn, and stripped the leaves and 

 fruit from grape-vines in some gardens at Saratoga Springs. For full 

 account of this insect, reference is made to Trans. iV. Y. State Agri- 

 cultural Society for 18oo, i)p. 477-484, and for notices. Country Gentle- 

 man, 1856, viii, p. 75, and in August, 1859. 



1864. Aphis on Apple-ti-ee buds. (The Country Gentleman, for 



June 2, 1864, xxiii, p. 351 — 10 cm.) 



Aphis mail received from Mr. J. J. Thomas, who finds the opening 

 flower-buds of his apple-trees in the early part of May, thronged with 

 the insects nestling close down among the pubescence. The insects are 

 the young of the apple-tree aphis hatched from eggs which had been 

 deposited late in the autumn in the crevices beneath the bark. They
