INTRODUCTION 
In the summer of 1936 a South American weevil, the “white- 
fringed beetle (Vaupactus leucoloma Boh.)” of recent entomological 
reports, was discovered near Svea, Fla. When and where the species 
gained entry into this country is not definitely known, but that it 
became established prior to 1936 seems certain, as it has since been 
found at several rather widely separated places in the Southeastern 
States. In 1937 it appeared in destructive abundance in limited 
areas along the Alabama-Florida border, and the United States De- 
partment of Agriculture, in cooperation with the States affected, has 
instituted a campaign designed at eradication.
