R. W. Burrell, a member of the laboratory staff, is now located 
at Homebush, Australia, in a field laboratory. As Homebush is just out— 
side of Sydney, Mr. Burrell retains his mailing address as, care of 
American Consulate in Sydney. Mr. Burrell is making a survey and study 
of the parasites of the rutiline Coleoptera. Those parasites discovered 
to date are all Diptera; however, Mr. Burrell finds tuat the Thynnidae 
(Hymenoptera) are abundant in species and it is expected that further 
studies will connect this parasitic group with some of the rutiline hosts. 
Dr. J. M. Rasek of the Moravian Research Institute for Plant Path— 
Ology, Czechoslovakia, spent February 6 at the laboratory. Dr. Rasek was 
much interested in the methods of rearing parasites.

Beetle Laboratory, Columbus, Ohio, visited this laboratory. Dr. Howard 
Speni much of his time discussing preblems and methods of parasite rear— 
ing; his success in rearing successive generations of tachinid parasites 
of the Mexican bean beetle throughout the winter months is not a common 
accomplishment, and the methods used were of much interest and value to 
laboratory members.
