the mere statement made of its habits. The ravages of the cucumber 

 beetle, Dlabrotica vittata, may usually be prevented by dusting the 

 plants with plaster of Paris and Paris green in the manner mentioned. 

 The squash-bug, Anasa t7-istis, must be fought by destroying its eggs, by 

 trapping as directed, and by repellants to prevent oviposition. 



Remedies for the Hop-louse. (New England Homestead, for July 27, 

 1889, xxiii, p, 253, c. 6 — 22 cm.) 



The best known remedies, are spraying the vines on the first appear- 

 ance of the insect with the kerosene and soap emulsion (formula given), 

 or the quassia and soap wash of the English hop-growers (formula also 

 given). By the proper use of the above means, serious losses may be 

 averted. 



The Yellow Woolly Bear. (New England Homestead, for July 27, 

 1889, xxiii, p. 253, c. 6. — 12 cm.) 



A caterpillar attacking many garden plants in Providence county, 

 E. I., is Spilosoma Virginica, known in the winged state as " the white 

 miller." The appearance and habits of the insect are given. They 

 should be picked from the plants and crushed. 



The Grain Aphis. (Country Gentleman, for August 1, 1889, liv, p. 579, 

 c. 2 — 15 cm.) , 



Heads of rye from Stone Kidge, N. Y., show attack of this aphis, 

 Siphonophora avence (Fabr.). Although the insect has been unusually 

 abundant in several of the Western States this year, this is the only 

 instance reported to me of its presence in New York, The heads con- 

 tained seven examples of the aphis, each one of which had been para- 

 sitized. If the parasite can be reared, its name will be given hereafter. 



Maple-Tree Borer. (Country Gentleman, for August 1, 1889, liv, 

 p. 579, c. 2, 3 — 23 cm.) 



Grubs working injuriously under the bark of maples in Stamford, 

 Conn., are probably those of Ghjcobius speciosus — a beautiful but per- 

 nicious beetle. A preventive of its attack would be painting the trunk 

 during July and August, from about its middle to (and including) the 

 base of the principal limbs with soft soap and crude carbolic acid. A 

 remedy is found in cutting out the young grub during August and Sep- 

 tember, when its presence is shown by the exuding sap, or later by its 

 "frass" or castings. 



The Cow-Fly. (Country Gentleman, for August 1, 1889, liv, p. 579, 

 c. 3 — 20 cm.) 



To a request from Freehold, N. J., for information regarding the cow- 

 fly [Hcematobia serrata], notices of it in the Country Gentleman, vol. liii, 

 1888, pp. 705, 759, 777, and 893 are referred to. For preventives of attack, 

 applications to the cattle of the following are suggested: Kerosene, 

 carbolic acid, soluble phenyle, tar-water, tansy-water, and naphthaline.
