This interesting gall, I take pleasure in naming after my friend Dr. R. 

 S. Turner of Fort George, Florida, who was the first to bring me speci- 

 mens. I have, however, since found it (juite abundant!}' on several trees 

 in Jacksonville. 



Two other globular wooly galls are known to me, Gtjnlps q. seminator 

 Harris, and Gi/nips q. operator Osten Sacken. My species may at once 

 be distinguished from these by its smaller size and by having but 13- 

 jointed antennae in 9 • ^' 'J- operator is 9 12-jointed antennae, .12 to 

 .13 inch. G. q. seminator 9 1-t-jointed antennse, black, and .11 inch.
