 parallel carina?. Wings hyaline, fringed, the veins dusky, the first 

 abscissa of the radius angulated. Legs and coxae faint yellow, claws 

 simple. Abdomen glabrous, highly polished, not punctulate, dorsally 

 more or less black-brown, the second segment surpassing somewhat 

 the middle, laterally very sloping; ventral-spine four to five times as

"Gall. The gall of this species was found on Quercus agrifolia; it is 

 a bud gall 8 mm. in diameter and more, globular, opaque, yellowish, 

 with some sparse brown spots, glabrous, apicrtlly with short and sparse 

 hairs and a small wart; the inner substance is brown, spongiose, and 

 encloses a globular, faint yellow, thick-shelled, monothalamous shell
