124 THE EEPORT OF THE No. 36 



Htmenopteea. 



During 1913, Mr. P. W. L, Sladen, of the Division of Entomology, has studied 

 several collections of aculeate hymenoptera, from various parts of Canada. In the 

 Ottawa district large collections have been made by Mr. Sladen, throughout the 

 season. Many of these have been definitely determined and records are given 

 below. We are specially grateful to Dr. S, Grfenicher, of the City Museum, Mil- 

 waukee, Wis., for determining many of the Apoidea. Some, it will be seen, are 

 not of uncommon occurrence, but little has been published regarding species 

 occurring in eastern Ontario.
