CAMPTONEUROMYIA n. g. 



This genus is a very well marked type which may be recognized 

 by the broadly oval wings having the third vein strongly arched, 

 rather well separated from costa and uniting therewith near the 

 distal third [pi. 34, fig. 5]. The antennae are sessile in both sexes, 

 and the ovipositor rather short and thick. One species which 

 has been reared breeds in ovate galls between adhering leaves of 

 Solidago, and also in loose apical bud galls. The latter may possibly 

 be only a modified form of the more common adherent type. The 

 last named is also inhabited by Asphondylia monacha

TROTTERIA Kieff. 

 Choristoneura Rubs. 

 Members of this genus are easily recognized by their abund- 

 ant scale covering and the peculiar character of the wings [pi. 34, 

 fig. 3]. Costa to the apex of the wing, subcosta and the third vein 

 are heavily scaled, the latter curving out distinctly from the nearly 

 straight costa and uniting therewith near the distal third. The 

 antennae are likewise peculiar to the genus, the first segment 

 being greatly produced [fig. 32] and having a length about three
