320 FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



He also positively asserts that tlie autumn generation deposit their 

 eggs in sloe bushes, whence their progeiiy emerge into the hop grounds 

 in the following season." This statement is corroborated by the fact, 

 that from another species of wild plum, Prunus mahaleb, M. Fons- 

 colomb described a new species of aphis, as Aphis pruni-mahaleb, which 

 subsequent researches showed to be identical with the hop-aphis. Dr. 

 Fitch is of the opinion, that after the death of the small and wingless 

 lice with the death of the vines, the winged ones fly away to the 

 nearest plum-trees, where they sustain themselves upon the leaves un- 

 til they have deposited their eggs, destined, if not previously de- 

 stroyed, to hatch the following spring. 



1865. Eatomological Correspondence. (The Country G-entleman, for 

 September 21, 1865, xxvi, pp. 190, 191 — 70 cm.) 



The YelloiD-necked Apple-tree Wcrrm, occurring in Lockport, N. Y., 

 about the 1st of August, upon hundreds of young apple-trees, some of 

 which they stripped of their leaves, is briefly described, together with 

 the moth that it produces, viz., Datana ministra (Drury). Reference 

 for a full account is made to Trans. N. Y. State Agricultural Society 

 for 1855, p. 467. The best remedy is to sever the twig with the con- 

 gregated caterpillars and drop them in a fire . 



Locust Hispa. Received from Locust Bay, L. I. The beetle, Anop- 

 litis Scutellaria Olivier [now Odontota scutellaris], is briefly described 

 and its natural history given. It is represented as very numerous at 

 Glen Cove, where the trees ravaged by it look as if burned by fire. 

 The insect has not been observed in the interior of the State. 



Black Prickly Wo7"ms eating the Leaves of Canada Thistles are identi- 

 fied as Cynthia car dui. It is parasitized hj Banchiis fugitivus Say.* 

 Some notes upon the butterfly are given. [For accounts of thistles and 

 briars completely stripped by these caterpillars, see Count. Gent, of 

 Sept. 7, 1865, p. 155, and id. for Oct. 5, 1865, p. 219.] 



1865. Address delivered before the Annual Meeting of the State 



Agricultural Society, Albany, February 8, 1865. (Trans- 

 actions ]Sr. Y. State Agricultural Society, for 1864, xxiv, 

 1865, pp. 111-116.) 



Attack of the hop plant-louse, the previous year in New York ; na- 

 ture of the attack, producing " honey-dew " and " black -blight " : the 

 insect identified with the Aphis humuli, of Europe ; its enemies ; reme-- 

 dies considered ; soap-suds not reliable ; tobacco-smoke recommended. 



1866, Joint-Worm in Wheat on Long Island. (The Country Gentle- 



man, for July 19, 1866, xxviii, p. 49 — 20 cm.) 



The larvae reported as infesting the joints of wheat at Glen Cove, L. 

 I., are probably the joint-worm, Eurytoma tritici, noticed in the Culti- 

 vator, October, 1851, viii, p. 323, and in Trans. N. T. St. Ayr. Soc. for 

 1861, pp. 830-841. As they are chiefly lodged at the lower joint, if 

 the wheat is cut above this point, the stubble may be turned under, 

 burying the insects while in their larval state so deeply that they 

 will be destroyed. 



* Limneria fugitiva (Say). For other Lepidoptera (six species of moths) upon which it 

 is parasitic, see Fourth Report on the Insects of Missouri, 1872, p. 41.
