The oval blister galls on oak produced by this species are so 

 insignificant as rarely to attract the attention of any but those 

 specially interested in the study of insect galls. This species was 

 reared in small numbers from several lots of galls taken by Miss 

 Cora H. Clarke on yellow barked oak, Quercus velutina, 

 at Magnolia, Mass., and also from blister swellings on the leaves 

 of red oak, Quercus rubra, taken in the vicinity of Albany, 

 N. Y. 



Gall. An irregularly oval pustulate swelling 5 to 6 mm in diameter 

 and showing equally on both surfaces but with no distinct nipple. 

 The galls are a variable brown in the fall, darker than the normal 

 tissue and occur here and there on the leaf. Apparently the same 

 species produces a slightly green or variable yellowish and red 

 elevation on both surfaces of the leaf some 5 by 7 mm in diameter. 

 Several larvae occur in the cavity beneath. 



Larva. Length 3 mm, whitish or yellowish, rather stout. Head 

 small; antennae short, stout. Breastbone well developed, bidentate, 

 the teeth rather long, stout; shaft well developed; segmentation
