Hymenoptera. 



In this Order, unfortunately, little definite work seems to have been done in 

 Canada in 1911. Small collections made in previo^^s years have been determined, 

 and data regarding some of these are now included here. Dt. Wheeler has deter- 

 mined a number of different species of ants, records of some of which are also given.
