Frank R. Mason, of Philadelphia, recently visited the Division of 
Insects and examined the coilection of beetles, including those telonging 
to the families Cerambycidae and Buprestidae. 
Lovis Thiel, of San Sebastian, Guatemala, visited the Division of 
Insects in October and left some interesting specimens which he had col- 
lected. Mr. Thiel formerly lived in Washington, but for six or seven years 
has been living in Guatemala, ani believes that it is not only a very 
healthful, but a very delightful place in which to live. Insects can be 
collected every day in the year and the climate is delightful.

B. L. Boyden, of Tampa, Fla., and W. H. White, of Washington, D. C.; 
recently attended a conference at Sanford, Fla., called by Dr. Wilmon 
Newell, State Plant Commissioner and Director of the Florida Experiment 
Station, to discuss problems relating to celery culture in Florida. fPre- 
liminary plans were made with representatives of the Bureaus of Chemistry 
and Plant Industry, U. S$. Department of Agriculture, and officials of the 
Florida Experiment Station and.State Plant Board for cooperative work on 
the leaf-tyer problem. En route, Mr. White stopped at Savannah, Ga., where 
he conferred with J. 0. Clark, of the Bureau of Chemistry, in regard to 
some contemplated cooperative experiments on arsenical residues on celery 
sprayed for leaf-tyer control. 
Walter Carter, of Twin Falls, Idaho, visited Riverside, Calif., to

Pa., and is located at the University of Pennsylvania, where adequate facili- 
ties have been offered for the conduct of his work. He is undertaking funda- 
mental research on the physiology of insects, including studies to determine 
the factor influencing the effectiveness of various poisons against wire- 
worms.
