The Peach-Tree Borer. 247 



Shotvvell and Thomas summarized. Finds there is but one brood of 

 the insect in a year. Thought he found the larvai in black knot on 

 plum trees. 



1827. Stabler, T. P. American Farmer, IX., 29 Experiments showing that a 

 mortar of cow-dung and clay was not always effectual. 



1833. Brown, T. Book of Butt., Moths and Sphinges, p. 17, fig. 63. Quotes 

 Worth (1823). 



1835. "Senex" (Kinderhook, N. Y.) The Cultivator, II., 40. First saw it near 

 Philadelphia in 1800, from whence it spread northward at the rate of 

 12 to 15 miles a year, reaching Kinderhook in 1807. Thought eggs 

 were laid on leaves on which larvse fed for a time. Mistook female for 

 a parasitic wasp. Apparently the first account of the insect in New 

 York literature. 



1839. Lancaster, S. The Cultivator, VI. , 133. Notes on development of insect 

 in Tennessee; no cocoons June 1st and a few found July 18th. Hens of 

 no use. Mounding good and facilitates digging out. 

 Harris, T. W. Sillman's Jour, of Sci. and Art, XXXYl., 312. Adults 

 described, with brief note referring to previous writings. 



1841. T/ie Cultivator, YIII., 90. Recommends planting a red cedar tree with 

 the peach; the odor of the cedar thought to keep the insect away. P. 95 

 records that Dr. Anderson, of Virginia, has practiced this method with 

 success. 

 Harris, T. W. Kept, on Insects of Mass. Inj. to Veg., 232-34. Good 

 general article, practically a recast of his 1826 article. In the 1842 edi- 

 tion, the 1852 edition (p. 253), and the Flint edition (p. 331) of Harris' 

 Report there is no change from the 1841 article, except that figures of 

 the larva, pupa and adults are added in the 1862 or Flint edition. 



1844. Gaylord W. Trans. N. Y. State Agr. Soc. for 1843, p. 161-62. Brief 



general account compiled from Harris (1841). Rather crude figures of 

 adults,' cocoon and pupa skin, evidently adapted from Saj^'s. Suggests 

 salt around tree. 



1845. Downing, C. Fruit and Fruit Trees, 460-61. Brief compiled account, 



not changed in subsequent editions. Recommends air-slacked lime or 

 ashes. 



1846. 2' he Cultivator, III., N. ser,, 217. Good general compilation, with illus- 



tration of work of borer in tree, and of a cocoon. 

 L'Hommedieu. Trans. Cincinnati Hort. Soc. for 1843-45, p. 17. Used 

 salt and saltpetre without success, but slacked lime gave good results. 



1854. Emmons, E. Nat. Hist, of New York, Agriculture. V., 222. Brief account 



compiled from Harris. PI. 36, figs. 1-5, male and female, larva, pupa 

 and cocoon. Fair, colored figures. 



1855. Fitch, A. First Rept. on Insects of New York, 108-117. One of the best 



accounts in the literature, by far the best up to that time. Detailed 

 descriptions of all the stages, including several varieties of the adults. 

 Larva and its work poorly figured.
