The abbreviation "Ace. No." refers to the Accession Catalogue of 

 the Survey and "Hart A:c. No." to a small Accession Catalogue of the 

 late Mr. C. A. Hart. The "Slide No." refers to the Survey collection of 

 slides. The data pertaining to the places and dates of types, as well as 

 full information regarding other matters of importance or interest, are 

 given with each type, allotype, and paratype. Much of this information 

 has never been published and in some cases even the locality of a type 

 has not been heretofore recorded. A few errors in the literature regard- 

 ing the localities of types, etc., have been corrected. Collectors' names, 

 where known, are given in parentheses following each record. For the 

 sake of completeness and usefulness, notes on synonymy have been added 

 and genotype designations indicated. No new synonymy, however, is here- 

 in published. The sequence of orders and families of the Natural History 

 Survey and the Bolter collections is arranged in a purely arbitrary man- 

 ner. The family arrangement of the A. D. MacGillivray collection of 

 Tenthredinoidea is in accord with his published classifications of 1906 and 

 1916. Generic and specific names in all cases are arranged alphabetically 

 under family and order groupings. 



Since most of the species of sawflies described by MacGillivray are 

 represented by types in his collection, ]\Ir. S. A. Rohwer has suggested the 

 desirability of publishing a list of the species the types of which are not 

 in the collection here, place of their description, and their present location 

 if known. This list is published as an appendix to this article. It is 

 probable that several species, the types of which have not been located, 

 are in the MacGillivray collection without identifying labels or a present 

 clue as to their identity. 



The following persons have greatly aided in the preparation of this 

 list by furnishing me with references, notes on synonymy, and other in- 

 formation and favors of a varied character: E. T. Cresson, Jr., L. H. 

 Weld, F. C. Baker, C. L. :Metcalf. F. H. Benjamin, H. Morrison. C. W. 

 Johnson, J. J. Davis, R. A. Cushman, J. R. Malloch, J. M. Aldrich, A. B. 

 Gahan, and particularly S. A. Rohwer.
