Carrot and Parsnip Apliides. (The Conntrv Gentleman for Sep- 

 tember 16, 1886, li, p. 695, c. 1-2 — 22 cm.) 



The unusual prevalence of plant-lice this year has caused 

 attack of crops which had before escaped, as the potato, tomato, 

 and now the above mentioned. No mention of injury to these 

 is recorded by our writers; is probably unusual in Eno^laiid. 

 Curtis mentions Aphis dated (Fabr.) on carrots, and Lichtenstein 

 records seven other species. Dr. Tliomas describes Siphocoryne 

 pastinac(2 as likely to occur on parsnips in this country, but not 

 yet detected ; two other European carrot-feeding species known. 

 Some remarks are made upon the cherry aphis, fMysus cerasi^ 

 reported with the above, as limited to one row ot trees in the 

 garden. Winds may not have been favorable to its general 

 distribution. 



A Ham-infesting Mite. (The Country Gentleman for September 

 16, 1886, li, p. 695, c. 2-3 — 28 cm.) 



A piece of smoked ham, from Bedford county, Pa., is infested 

 with a mile, recognized as the cheese-mite, TyrofjlypliuSi siro 

 (Linn.), identical with T. farhne and T. saccharic trom flour 

 and sugar. The same mite -recenth' infested hams in a New 

 York City provision store, received from a western packing 

 house. De Geer has recorded it as infesting smoked meats in 

 Europe. The mite, unless very abundant, would become innocu- 

 ous in cooking the ham. The attack fails to be arrested through 

 washing with hot soap-suds or by re-smoking. A remedy would 

 be a wash of one part carbolic acid dissolved in ten of alcohol, 

 diluted with ninety of water. 



The Cockscomb Elm Gall. (The Country Gentleman for Sep- 

 tember 23, 1886, li, p. 713, c. 3-4 — 35 cm.) 



The galls, received from Mercer county, N. J., are described, 

 and their growth, with the life-history of their occupant, 

 Glyphina ulmicola (Fitch), given. The honey-dew that the 

 galls contain is noticed. The gall is believed to be confined to 

 young trees of the white elm, Ulm.us Arnericana. The aphis is 

 only vulnerable after leaving the gall, when it may be sprayed with 

 soap-suds and quassia or tobacco water. Tlie synonymy and 

 bibliography of the species is given, under Bryoscripta^ Theiaxes^ 

 Pemphigus^ Colopha and Glyphina.

 tember 23, 1886, p. 715, c. 2-3 — 20 cm.)
