Mr. Howard presented a paper before the American Association of Econemic 
Entomologists on recent developments in Mexican bean beetle studies and 
Mr. Camphell presented a paper before the same organization on the celery 
leaf-tyer in California. Mr. Fink presented two papers before the Ento- .. 
mological Society of America, dealing principally with studies in insect 
physiology. His first paper was entitled "Metabolism daring “fmbryonic 
Developmeht of Eggs and Metamorphic Changes of Pupae of Insects;" the 
second, "Factors in the Hibernation of Leptinotarsa decemlineata." 
In addition’ to attending the meetings, W. A. Thomas consulted office 
records on the mole-cricket, preparatory to enlareing his investigations 
on this insect. 
C. E. Smith will remain in Washington for a short time to do neces~ 
sary library work in connection with studies on certain insects as trans- 
mitters of plant diseases and to review the literature on Larra ae 
a parasite on mole-crickets 
K. L. Cockerham has just submitted his report on the clean-up 
Operations in connection with the campaign for the eradication of the — 
sweet-potato weevil in southern Mississippi, which is being conducted in 
cooperation with the Mississippi State Plant Board, Owing to the unusually 
cold winter and the dry season during last summer, the insects have been 
greatly reduced in numbers, and it is expected that these factors, aided by 
the intensive clean-up campaign, will greatly reduce the number of infesta- 
tions of this insect in the Gulf-Coast counties of Mississippi. Mr. 
Cockerham also reports that the State Board of Agriculture of Alabama has 
recently enacted regulations covering the campaign in that State for the 
eradication of the sweet-potato weevil and it has made arrangements to 
supply certified planting stock to the owmers of weevil-infested properties 
in Mobile County. This action should greatly expedite the work in Alabama, 
Prof, R. W. Harned and Clay Lyle, of the Mississippi State Plant. 
Board, and Dr. J. H. Montgomery, of the Florida State Plant Board, visited 
this office at the time of the scientific meetings just held in Washington 
for the purpose of discussing arrangements for the campaign to eradicate the 
sweet-potato weevil in their respective State.
