Lindroth CONTENTS Page Introduction 117 Changes in synonymy 120 Discussion of certain species groups 143 Species new to America 157 Bibliography 159 INTRODUCTION Thanks to a generous grant from the Rockefeller Foundation, I was able in the spring of 1951 to spend four months on museum studies in the United States and Canada. The main task was to carry out the basic taxonomic work for a carabid fauna of Newfoundland. I started with the determination of my own material, collected in 1949 with a grant from the Arctic Institute of North America, and then proceeded with the study and revision of the Newfoundland material in the larger public and private collections, as far as available. Labrador and Nova Scotia records were listed at the same time. Eventually the study was enlarged to cover all carabid species common to Europe and North America with the purpose of making a revised list for publi-cation. Occasionally other special taxonomic problems were attacked. Thus preliminary work was done for revisions of the North American species of Diachila, Blethisa, Notiophilus, Pristodactyla, and Europhilus. The results obtained will appear in a series of papers, in part regional (covering Newfoundland, Nova Scotia, and Labrador), in part purely taxonomic (on the genera mentioned above and on the Kirby types). It seems convenient, however, to present h^re a summary of all changes proposed in the nomenclature of North American Carabidae, especially as some of them are not concerned with the special investigations mentioned. In the latter cases full reasons for my opinions are given here, but in the others the reader is referred to the special papers mentioned above. As a rule, only new synonymies are listed, but in a few cases the confirmation of already accepted synonymies by re-examination of typical specimens is considered worth giving. In three cases {Bcmhidion concolor, Pterostichus mandihularis, Agonum affine) the revised synonymy unfortunately requires that a
