75. Three Years Observation on the Biology of Popillia japonica . 
(10 min.) (Lantern.) C. A. Thomas, Riverton, N. J. 
A comparison of the important phases in the life-cycle of Popillia for the years 1922- 
1924 inclusive.

B. R. Leach and W. E. Fleming, Riverton, N. J. 
The soil-ball is fumigated with carbon disulphide vapor, the foliage being submerged

77. Coated Arsenate of Lead and the Physical Chemistry of the 
Coating Process. (10 min.) E. R. VanLeeuwen and Dr. P. A. van der- 
Meulen, Riverton, N. J. 
This paper deals with the coating of lead arsenate with a metallic soap and its use 
against the Japanese beetle. When lead oleate is precipitated under proper 
conditions it forms an intimate mixture consisting of globules of lead oleate with 
uncoated particles of arsenate of lead. After drying the lead oleate spreads 
upon the surface of the arsenate of lead powder and upon the leaf and pro¬ 
duces a coated material which adheres very firmly to the leaf surface. 
78. Geraniol, a Primary Attractent of the Japanese Beetle. (10 min.) 
(Lantern.) Loren B. Smith and E. A. Richmond, Riverton, N. J.
