The midges were reared from an irregular stem gall occurring 

 upon a weed abundant in wet places at West Nyack, N. Y. Galls 

 were first observed April 18th and adults obtained June 2 2d. 

 Eupelmus dryorhizoxeni Ashm., Eurytoma, Polyg- 

 notus and Torymus species were reared from this gall. 



Gall. Length .7 to 1.5 cm. It varies in form from subglobular 

 to elongate, irregular, fusiform. The interior is hard, pithy, the 

 larger ones at least are polythalamous. 



Larva. Length 3 mm, slender, pale orange. Head small, antennae 

 slender; breastbone slender, bidentate, with a minute median tooth; 

 skin coarsely shagreened; posterior extremity broadly rounded. 



Male. Length 1.75 mm. Antennae dark brown , basally yellowish ; 

 20 segments, the fifth with a length a little greater than its diameter; 

 terminal segment produced, obovate. Palpi; the first segment 

 irregularly subquadrate, the second about twice as long, stouter, 

 rounded apically, the third a little longer than the second, dilated 

 apically, the fourth about twice the length of the preceding, more

 of silvery white scales, the black eyes narrowly margined posteriorly 

 with silvery white. Mesonotum a dark reddish brown, variably
