WHOLE VOL. APPLIED ENTOMOLOGY HOWARD I9 



Scudder, Packard, J. L. Leconte, and Horn stood out in their 

 generation as the most distinguished American entomologists. 



A complete and beautiful account, by A. G. Mayor, of Scudder's 

 life will be found in Memoirs of the National Academy of Sciences, 

 Volume 17, pp. 81-103. 



C. V. Riley's first papers were published in the Prairie Farmer for 

 1863. The importance of his work is so great that it will be separately 

 considered on later pages. 



In 1864 appeared the first article by Dr. Isaac P. Trimble. Doc- 

 tor Trimble was a successful fruit grower, whose first contribution 

 to entomology was published in the Proceedings of the American 

 Pomological Society of that year. It considered the codling moth and 

 the plum curculio. Altogether there are nine titles of record under 

 his name. The most pretentious one is a quarto volume of 139 pages, 

 illustrated by very fair plates, entitled "A Treatise on the Insect Ene- 

 mies of Fruit and Fruit Trees," published in 1865, apparently as a 

 private publication. 



According to H. B. Weiss, the Report of the Executive Committee 

 of the New Jersey Agricultural Society for 1866 states that the 

 legislature had appropriated three thousand dollars to the Society for 

 preparing and publishing this treatise of Doctor Trimble's and that the 

 money was to be paid in yearly installments of one thousand dollars. 

 It was further stated that none of this money went to the author but 

 was used by the Society in publishing and purchasing copies of the 

 book for distribution. " Eight dollars were asked for a copy with 

 colored plates, and five dollars for one without colored plates." Doc- 

 tor Trimble was 61 years old at the time of publication of this book ; 

 and he lived to be 86. W. G. Johnson (Proceedings of the Entomo- 

 logical Soc^iety of Washington, Vol. 4, pp. 230-233) states that Doc- 

 tor Trimble had planned two additional volumes and that many of 

 the plates were prepared and that these and other illustrations had 

 come into his (Johnson's) possession. In the opinion of Mr. John- 

 son, the work that Trimble did alone and unaided " entitles him to a 

 prominent place with the early economic entomologists of this 

 country." 



In 1865 three new writers appeared in the field of agricultural ento- 

 mology. A. E. Verrill, afterwards a famous zoologist and head Pro- 

 fessor of Zoology at Yale University, published that year in the Prac- 

 tical Entomologist a note on the woolly root-louse of the apple. Five 

 years later he published two long papers on the external and on the 

 internal parasites of domestic animals, in the Fourth Annual Report 

 of the Secretary of the Connecticut Board of Agriculture, following
