Dr. Bernard Trouvelot, professor in the Ecole Nationale d'Horti- 
Culture, Versailles, France, who is now a travelling fellow of the Rock-— 
efeller Foundation, made several visits to the Division in April. One 
of Dr. Trouvelot's problems while he is in this country is to find out 
whether it will be advisable to intrcduce into France the tachinid para- 
Site of the potato beetle, as the beetle now occurs in that country. Dr. 
Aldrich has agreed to send him identified material as a basis for his 
work on the parasite. 
H. S. Barber went to Boston April 1, and spent two days there com-— 
paring specimens of Coleoptera with types of Le Conte species in the 
Museum of Comparative Zoology. 
GIPSY MOTH AND BROWN-TAIL MOTH INVESTIGATIONS 
A. F. Burgess, Senior Entomologist, in Charge 
K,. A. Salman, of the Entomological Department of the Massachusetts 
Agricultural College, visited the office and laboratory at Melrose High-— 
lands on March 16. 
A. F. Burgess spent a part of the week of March 19 in Washington. 
F. P, Washburn, Commissioner of Agriculture of Maine, called at 
the office on March 22 to discuss the gipsy moth work in that State. 
At Melrose Highlands on March 27 a conference pertaining to the 
gipsy moth work in the State of New York was held with H. L. McIntyre, 
of the New York State Conservation Commission. 
In April W. B. Cartwright, of the Division of Cereal and Forage 
Insects, in charge of the field laboratory at Sacramento, Calif., and 
A. B. Baird, Entomologist, in charge of parasite work, Chatham, Ont., 
visited the gipsy moth laboratory, 
S. M. Dohanian, Asscciate Entomologist, who has been connected 
With the gipsy moth and brown-tail moth parasite work for several years, 
was transferred to the European Corn Borer activity at Arlington, Mass., 
on April 16. At times Mr. Dohanian has suffered considerably because of 
the more or less constant exposure to the hairs of the gipsy moth and 
the brown—-tail moth, and it is hoped that the new work will be less harm- 
Tul to his health. 
The gipsy moth parasite laboratory at Budapest, Hungary, has been 
moved to Kapy utca 21, Budapest 2.
