The gall was first noticed by Osten Sacken in 1862 and subse- 

 quently the larva and gall were figured and described by 

 Beutenmueller. The gall is rather common about Albany and 

 Poughkecpsic, N. Y., and probably other places in New York State, 

 on Solidago canadensis. Adults were reared in early 

 October. Polygnotus and Torymus species were reared from this 

 midge.
