 ENTOMOLOGY AT THE CONVOCATION WEEK MEETINGS 



OF 1919-20 



The programs of the meetings of scientific societies held be- 

 tween December 29, 1919, and January 3, 1920, for which we 

 have data, list 128 papers on entomology, or at least on insect 

 material; 118 of these were to be given at St. Louis; 10 were 

 read at Princeton, New Jersey. 



Of the societies meeting at St. Louis, Section F of the Ameri- 

 can Association for the Advancement of Science and the 

 American Society of Zoologists were jointly credited with 15, 

 i of these (by invitation) being on polyembryony and sex, 2 

 on cytology, 6 on genetics, 4 on ecology and general physiology 

 and 2 on comparative anatomy. The cytological papers were 

 based on Tettigidae, those on genetics on Drosophila. As 

 1919 was a great event in the ly-year cicada calendar, this 

 insect supplied material for one physiological and one anato- 

 mical paper. 



The Entomological Society of America provided II titles 

 on ecology and general physiology, 3 on comparative anatomy 

 and 2 on taxonomic groups. Of special interest was the sym- 

 posium: "The Life Cycle in Insects," treated by taxonomic 

 groups, by nine speakers (Messrs. Folsom, E. M. Walker, 

 Ball, Fracker, Chapman, C. L. Metcalf, Cockerell and Forbes 

 and Dr. Edith M. Patch), and the annual address before the 

 Society, this year by Dr. W. J. Holland, on "The Evolution 

 of Entomological Science in North America." 



The American Association of Economic Entomologists 

 furnished the great bulk of entomological papers 73 includ- 

 ing President W. C. O'Kane's address, "The Day's Work. " 

 Among these were 2 on mosquitoes, I on ticks and I on exter- 

 nal parasites of stock and poultry, 2 on the pink bollworm, 3 

 on corn borers, 9 on insecticides, 12 on various aspects of bee- 

 keeping (in the Apicultural Section), 6 before the section of
