sites were coming out on arrival. Moreover, the box was not tight. On the day 

 following the arrival of the sending, Mr. Kotinsky brought together thirty adults 

 which were active and mated freely. Elm leaves daubed with honey were supplied to 

 them for nourishment, but they gave little attention to it. No elm leaf-beetles were 

 found in Washington, and Mr. Kotinsky, on receipt of a telegram from Mr. Sanders 

 to try Philadelphia, bottled the colony and took it to that city. With Mr. F. M. 

 Trimble, one of Mr. Sanders' assistants, a search for the elm leaf-beetle was first made 

 in Logan Squo.re opposite the Philadelphia Academy of Natural Sciences, where they 

 were accompanied by Dr. Henry Skinner, and later in Fairmont Park, but to no 

 avail. Finally eggs of the elm leaf-beetle were located near the Andorra Nurseries, 

 City Line, Chestnut Hill, Philadelphia, and most of the parasites were released on the 

 south side of Barren Hill Road, middle tree (eighth from either end), between the 

 first and second road entrances to the nursery grounds. Eggs confined with the 

 insects in a vial prior to their release did not seem to attract them. 



In the meantime. Prof. Robert Matheson, of Cornell, had notified the WTiter that 

 some eggs were still unhatched at Ithaca, and, on orders from the Washington office 

 Mr. Kotinsky mailed the remaining parasites to Ithaca. 



On Mr. Kotinsky's return to Washington, a few more parasites were found to have 

 issued, and eventually these were released, on the 19th of July, on an elm tree in the 

 back yard of 1914 Sixteenth Street, where fresh elm leaf-beetle eggs were found. 



Professor Picard promises another sending in 1918, and the writer will be glad if 

 entomologists interested wiU notify him of their wish to attempt the colonization in 

 regions of elm leaf-beetle abundance next June.

THIRTIETH ANNUAL MEETING, AMERICAN ASSOCIATION 



OF ECONOMIC ENTOMOLOGISTS, PITTSBURGH, PA., 



DECEMBER 31, 1917 TO JANUARY 2, 1918. 



The Thirtieth annual meeting of this Association will be held at Pittsburgh, Pa., 

 on the dates above mentioned. Sessions will also be held for the section on Apicul- 

 ture and the section on Horticultural Inspection. 



The exact hours of holding the sessions of this Association and its sections, together 

 with the program, will be published in the December number of the Journal of 

 Economic Entomology. It is planned to devote one session to a symposium on 

 some important phase of insect investigations. 



In order for papers to be included in the program, it will be necessary for the titles 

 to be filed with the Secretary on or before November 10. Papers should be prepared 

 so that they can be presented in not to exceed fifteen minutes ; and it is suggested that 

 if the subject which is covered will require a longer time, that an abstract be read. 



Titles of papers to be presented before the section on Apiculture should be for- 

 warded to the Secretary of that section, Mr. N. E. Shaw, Secretary of Agriculture, 

 Columbus, Ohio. Titles on Horticultural Inspection should be forwarded to the 

 section on Horticultural Inspection, Prof. J. G. Sanders, Economic Zoologist, Harris- 

 burg, Pa. 



Entomologists desiring to become members of the Association can secure the 

 necessary blanks from the Secretary or from Prof. J. G. Sanders, Harrisburg, Pa., 

 who is the Chairman of the membership committee.
