This species was reared the latter part of July 1907 from a pecu- 

 liar, greenish or purplish, pouchlike gall occurring on narrow- 

 leaved Solidago, S. g r a m i n i f o 1 ia , at Albany, N. Y. 



Gall. The gall ranges in length from 2.5 to 5 cm, tapering grad- 

 ually from an enlarged base to a very slender, frequently curved 

 tip. It is composed of two or more leaves, the folded edges of 

 which have become adherent. It varies in color from greenish to 

 purplish and the interior is inhabited by yellow larvae.
