Mr. E. A. McGregor reports it as attacking also the American elm 
{Ulmus americana) and two other varieties of elm (Ulmus spp.), 
the willow (Salix sp.), the white oak (Quercus alba), and the pecan 
( Hicoria pecan), at Batesburg, S. C. He records it also on elm ( Ulmus 
sp.) from Columbia, S. C, and Laurinburg, N. C. These records in- 
dicate a probable wide distribution of this red spider through the 
South. In Florida the writer has found this species along both the 
cast and west coasts, including Miami Beach, Miami, Biscayne Key. 
Homestead, West Palm Beach, Florida City, Fort Myers, Braden- 
town, Oneco, and Winter Haven.
