AMERICAN HYMENOPTERA. 65 



the third submarginal cell near the middle in the females. In one 

 male (Mass.) it is received near the third cross-nervure, and with an- 

 other (111.) at the junction of the second and third cells. In all^ the 

 spot below the stigma is nearly round, extending nearly or quite across 

 the second submarginal cell. The next species agrees with Leach bet- 

 ter than this in the wings, but as this has come to be considered H. 

 McLp.ayi, and is very common, while the other is rare, it seems better 

 not to change the name, at least until more specimens of that are seen.
