246 THE CANADIAN ENTOMOLOGIST 



Reference to the more important publications such as Hamp- 

 son's and Smith's catalogues, monographs, and to figures, 

 stating in each cases the genus to which the name has been 

 variously referred, and dates of the publications. 



Important synonymic references. 



At the bottom of the card, if the name stands as the prior 

 one for a species, all the later names are given, with authors and 

 dates, numbered in order of priority, those that stand for recognizable 

 variations being so indicated. Or, if a synonym or variety, the first 

 name only of the species is referred to, e. g., " =alpha Sm., 1891" 

 or " =var. of alpha Sm., 1891," the authority for such references 

 being elsewhere given on the card. Since, as before mentioned, 

 each synonym or variety has a card to itself, a few species have 

 twenty or more cards. A certain European Tortrix would re- 

 quire nearly seventy, allowing only one for each name. When 

 space fails, another card has to be added, and the fact indicated 

 at the top of each. At the top corners of the card are given: 



Reference to the page in note-books where the form is dealt 

 with. 



Reference to the number of the slide on which genitalia have 

 been mounted. 



Reference, when thought desirable, to the drawer or box con- 

 taining the species in the collection. 



On the reverse side of the card is given the sex, locality and 

 present location of each known type and co-type, together with 

 the number, sexes, and localities mentioned in the original descrip- 

 tion. 



A great deal of time has been spent in preparing this index, 

 which has obviated more congenial work, but it has proved to be 

 of the highest value and utility, as entire knowledge of literature 

 and personal study of any name can be discovered in a moment, 

 with little trusted to memory alone. 



There is also a full MSS list of the N. American Noctuid«, in 

 Hampson's order and names, but revised to correspond with the 

 arrangement in the collection. The recent synonymy only is 

 given, original or otherwise, and all names which are considered 

 to refer to recognizable varieties are entered as such. This list is
