Provinces, in order from east to west, e.g., N.S., Ont., 

 B.C., etc. The characteristic faunal zones inhabited by 

 the species will be indicated, so far as it may be possible, 

 by abbreviations; thus: Ar. -Arctic, H.-Hudsonian, C.- 

 Canadian, T. -Transition, Au.- Austral. Where a species 

 is known from a few localities only, the names of 

 these will be given with the name of the captor in 

 cases where the species recorded is of great rarity. 



(c). If the type locality of a species is Canadian it will be 

 given, and the places where type specimens of Canadian 

 species are deposited will also be given when possible. 



(d). The Latin name of the chief food plants will be given 

 in the case of the Lepidoptera, Cecidomyiidae, Aphidae, 

 Coccidae, Phytophagous Hymenoptera and Coleoptera. 

 (Gray's New Manual of Botany will be used throughout 

 for the names of the food plants). 



(e). In the case of parasitic species the name of the host 

 or chief hosts will be given wherever known. 



5. Recent important changes in synonymy will be noticed. 



6. In the case of new and previously unpublished records 

 the collector's name will be given in every case. 



7. No species of which there is no trustworthy record or 

 specimen available is to be included. 



8. Fossil species will be included, and also introduced species, 

 including greenhouse species, but the fact that they have been 

 introduced will be indicated in those cases in which the fact is 

 known. 



The work of preparing the catalogue will be divided among 

 the members, approximately, as follows: 



Aptera, Orthoptera and Neuropteroid orders. Dr. E. M. 

 Walker. 



Hymenoptera. Messrs. W. H. Harrington, G. E. Sanders, 

 and Prof. T. D. A. Cockerell. 



Coleoptera. Messrs. J. M. Swaine, G. Chagnon, N. Criddle, 

 and J. D. Evans. 



Lepidoptera. Messrs. Arthur Gibson, H. H. Lyman, A. F. 

 Winn, and F. H. Wolley-Dod. . 



Dipt era and Siphonaptera. Dr. C. Gordon Hewitt. 



Hemiptera. Prof. T. D. Jarvis, and Mr. G. A. Moore. 



These members will be responsible for the lists prepared by 

 them, and such lists will be published under their names. In 

 the preparation of such lists it will be necessary to seek the 

 co-operation and assistance of other specialists and all such 

 assistance will be fully acknowledged. 



The division of the work in the different orders will be
