W. A. Stevenson, of the Tallulah laboratory, has returned to 
Arizona to continue studies on the Thurberia weevil in cultivated cotton 
in the Santa Cruz Valley. 
In the last few days of May Professor Bernard Trouvelot, of the 
Ecole Nationale d'Horticulture, Versailles, France, was a visitor at 
the field laboratory at Tallulah, La., to study the organization and 
methods of the laboratory, and the literature on cotton insects, and to 
make contacts that will assist him in his investigations. Professor 
Trouvelot has begun a trip around the world to study the ecology of cer- 
tain cultivated plants and their insect enemies under different conditions 
of soil and climate, and is particularly interested in the subject of 
insect control by means of the introduction and propagation of parasites 
and predators. 
On May 28 and 29 Dr. W. V. King visited Florence, 5. C., to confer 
with Dr. G. M. Armstrong with regard to studies of the cotton leaf hopper. 


GIPSY MOTH AND BROWN-TAIL MOTH INVESTIGATIONS 
A, F. Burgess,.Senior Entomologist, in Charge 
Dr. M. T. Smulyan, of the gipsy moth laboratory, spent about a 
month in April and early in May at the U. S. National Museum, studying 
the genus Perilampus, with a view to preparing a revision of it. 
On May 31 a conference was held at Hartford, Conn., to discuss 
the gipsy moth situation, Dr. W. E. Britton, State Entomologist of Con- 
necticut, acting as chairman. The speakers at the conference were Dr. 
T. J. Headlee, State Entomologist of New Jersey, G. W. Howard and H. L. 
McIntyre of the New York State Conservation Department, Dr. T. L. Guyton 
of the Bureau of Plant Industry of Pennsylvania, J. T. Ashworth of Con- 
necticut, W. A. Osgood of New Hampshire, George A. Smith of Massachusetts, 
H. L. Bailey of Vermont, E. L. Newdick of Maine, H. Horovitz of Rhode 
Island, and A. F. Burgess of the U. S. Department of Agriculture. Much 
of the discussion emphasized the recent increase in the abundance of the 
gipsy moth and the present danger of its spreading into the barrier zone, 
the opinion of the meeting being that considerable suppression work as a 
protection to the zone should be done just east of it. 
_ A. F. Burgess and S. S. Crossman spent several days of the week of 
May 21 in Washington, in conference with department officials. 
Professor J. A. Manter, of Storrs, Conn., with several students 
of entomology, visited the gipsy moth office and laboratory on May 25. 
a On May.31 the season in New England was about ten days late, as 
indicated by the development of the foliage and the hatching of gipsy moth 
eggs. On this date hatching was practically completed.
