OLIGOTROPHIARIAE 
This group 1s composed mostly of rather large species which 
may be recognized by the third vein being well separated from 
the anterior margin, the rather short cylindric antennal seg- 
ments, and the simple claws. |

The following tabulation of the known galls produced hy 
members of this group will undoubtedly prove of Service itl
