PREFACE. 



The following general Index to the thirty annual Reports of the Entomological Society of 

 Ontario, on noxious, bene6cial and other insects, has been prepared by direction of the Hon 

 the Minister of Agriculture for Ontario. It has been thought advisable to include all references 

 to birds, plants, etc., as well as to insects, in one index and thus save the trouble of turning 

 from one part to another. For the same reason also, insects are referred to under their specific 

 as well as generic names, and changes of nomenclature are given as far as possible. Superseded 

 names are placed in brackets, e.g., abdominalis, Bracliynemurus (Myrmeleon), denotes that the 

 species is mentioned under the genus Myrmeleon, but is now included in Brachynemurus. 



Some of the earlier volumes, namely, i, ii, iii, viii and x, were published in the reports of 

 the Department of Agriculture with the numbers of their pages following those of the lar<^er 

 volume ; they were also issued separately with an independent pagination. All the references to 

 these volumes have been given with the numbers referring to the larger volume in brackets e.n 

 Abbotii, Thyreus, iii : 13 (380) ; the number of the volume being in Roman numerals 



In deciding questions of nomenclature the following authorities have, for the most part 

 been followed : 



Prof. J. 3- Smith's List of Lepidoptera of Boreal America, 1891, and Insects of New Jersey, 

 1899 ; Henshaw's List of Ooleoi)tera, with Supplements ; Scudder's Revision of the Melanopli ; 

 and Bank's Bibliography of American Economic Entomology. 



As many of the earlier reports were not numbered, but distinguished only by their dates 

 a list is given of the volumes and the years to which they belong.
