The midges were first reared by the late Dr M. T. Thompson of 

 Clark University, Worcester, Mass., from an oval stem gall on 

 boneset, Eupatorium perfoliatum. This gall is rather 

 common at Springfield, Mass., at Nassau, N. Y., and has been 

 observed in the vicinity of Buffalo as well as in other sections of the 

 State. It is fairly common in Ontario, Canada. The larvae winter 

 in the gall, the adults appearing probably in May. Several para-, 

 sites were obtained, namely, Eupelmus dryorhizoxeni 

 Ashm., Platygaster obscuripennis Ashm., Polyg- 

 notus sp. and Torymus sp.
