length and variety. In recognition of the occasion, a special program 
and dinner at the Faculty Club of Harvard University were held for 
the 29 members and one guest present. W. L. W. Field was toast- 
master of the evening; he read the minutes from the first Club 
meeting in 1874, and a letter from Henshaw expressing regret at 
being unable to attend. The first after-dinner speaker was Nathan 
Banks, who “emphasized the need for specialization and the further- 
ance of systematic entomology.” Next, C. W. Collins, of the Parasite 
Laboratory in Melrose Highlands, brought the felicitations of the 
Bureau of Entomology and traced the. development of economic 
entomology during the Club’s existence. C. T. Brues gave a humor- 
ous account of “some of the peculiar and amusing incidents” con- 
nected with his editorship of Psyche. C. W. Johnson and A. P. 
Morse spoke on the history of the Club (with no extant record of 
their remarks) . Following these speeches, a motion picture on the 
life history of the yellow fever mosquito was shown. And then the 
regular scientific program of the evening began, a talk by Dr. Joseph 
Bequaert on “Some Problems of Medical Entomology in Guatemala.” 
When the 500th meeting finally adjourned, it was 1 1 :00 p.m. 
Between 1920 and 1940, there occurred a striking transition in 
the composition of the Cambridge Entomological Club. Through the 
early twenties, the Club consisted of “not-all-terribly-old amateurs, 
more or less old professionals, and a few young people” [31]. But 
it was the custom in those days to pass the presidency and vice-presi- 
dency of the club around among the senior people, and so rotated that 
every few years the same man would be president again. In 1929, 
however, the tradition was broken by the election of Frank M. 
Carpenter, then a research fellow, to the presidency. His address as 
retiring president at the end of the year was published in the next 
issue of Psyche [32]. Dr. Carpenter was reelected as president for 
the following year, thus once again breaking tradition, for he was 
only the third person in the history of the Club to hold two successive 
terms of this office.* From this time the Club began to have an 
increasing number of younger members, including graduate students, 
as its officers. 
*The others were Edward Burgess, 1879 and 1880; and J. H. Emerton, 
1904 and 1905. In later years there were two other reelections: C. T. 
Brues, 1944 and 1945; and E. O. Wilson, 1954 and 1955.
