1910] The Ottawa Naturalist. HI 



presents in convenient form what purports to be a complete 

 list of these insects from the North American region. The 

 author has had the co-operation of the leading students in this 

 order in the preparation of the catalogue; the classification and 

 nomenclature employed, therefore, represents the more approved 

 and advanced ideas of odonatologists. The publication is an 

 im.portant one, and will undoubtedly be much sought after. It 

 should be in the hands of all Canadian students of these 

 neuropteroid insects.

 of Ontario has recently appeared, and as usual contains much 

 valuable information about the insect pests of Canada, especiallv 

 those injurious to the crops of the Province of Ontario. As most

 all can profit by reading the excellent assortment of papers 

 presented.
