are as accessible as possible. If possible reference will be 

 given to a good published figure, and if such is contained in 

 one of the references it will be indicated by the addition of 

 (fig.) after the reference. 



(b). The geographical distribution within Canada and Newfound- 

 land ; this will be indicated, as a rule, by Provinces, in order 

 from East to West, e.g., N. S., Ont., B. C, etc. The char- 

 acteristic 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.-Transi- 

 tion.* 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, Cecidomyidae, Aphidae, Coccidse, 

 phytophagous Hymenoptera and Coleoptera. (Gray's New 

 Manual of Botany, 1908, 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 In the case of new and previously unpublished records the col- 

 lector'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, in- 

 cluding 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 mem- 

 bers, 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. 



It is intended to publish a map indicating^ these zones at an early date in 

 this journal.
