Cincticornia globosa Felt 

 1909 Felt, E. P. Econ. Ent. Jour., 2:291 



This dark-brown species with short, relatively broad wings was 

 reared in some numbers from a subhemispheric, brown, slightly 

 nippled, oak leaf gall on black oak, probably Q u e r c u s 

 velutina, in April and May 1909 from material collected by Miss 

 Cora H. Clarke at Magnolia, Mass., in October 1908. Apparently 

 the same gall was taken by Miss Clarke on the scarlet oak, 

 Quercus coccinea. A very similar oak leaf gall may produce 

 a Cynipid.
