ing black,- with the second segment concealing the following ones 

 in dry specimens. Male : body slightly longer than in the female ; 

 antennae 15-jointed, the first joint dark at the base, the second 

 yellow, globular, base of the third yellow, its tip thickened, 

 remaining joints dusky brown; head, thorax and abdomen black; 

 legs slightly darker than in the female. 



The galls of this species grow on slender peduncles on the 

 edges of the leaves of Quercus rubra and Q. coccinea. They are 

 ovate with a long curved point, 3 by 4 mm. in dimensions exclu- 

 sive of the tip and the peduncle, which latter is from 6 to 12 mm. 

 in length and is evidently the prolongation of the lateral leaf 

 veins. When fresh the gall proper is smooth and has a somewhat 

 glaucous hue which mostly disappears in drying, at which time 

 there is a change to a dark, dirty, olive brown color. The larval 

 cell, which is free, smooth and oval, is 1 by 2.5 mm. in dimensions. 



Type locality: Waterbury.
