The writer in the main has followed the classification proposed 
by Rohwer in the Hymenoptera of Connecticut. This classifica- 
tion seems to be the most natural yet proposed for this super- 
family of Hymenoptera, since it brings together groups which 
are obviously closely related and yet have been widely separated 
in current former classifications. It also has the advantage of 
being more workable and less cumbersome than those formerly 
proposed.

The synonymical notes include only the reference to the orig- 
inal description, the latest monographic reference, if any is avail- 
able, and in a few cases other important synonymy. Under each 
species is given the total number of male and female specimens 
in the collection which have been taken within the state. The 
various localities are also cited, together with the number of 
specimens from each locality. In almost every case the earliest 
and latest seasonal date is given, as well as the names of the 
flowers visited.
