About this book

The main objectives of this work are to list the species of leafhoppers that have been found in Canada and Alaska, to summarize available information on their bionomics and distributions, and to define the chief taxonomic characters so that specimens may be named without necessarily a knowledge of the systematics of the group.

DeLong and Knull (1945) listed under 170 species known to occur in Canada or Alaska. Four hundred and eighty species are discussed below. In this study a number of new species were discovered. Twenty-five of these have been described elsewhere, by the author or others, and are included below; and the remainder, most of which are species of Empoasca or Erythroneura, await description when the groups to which they belong are revised. In addition, some 105 names that were previously treated as valid specific names have heen definitely or tentatively reduced to synonymy, either in earlier papers (Beirne 1950-5) or in the present work.

There are good reasons to believe that more species than those discussed below occur in Canada or Alaska. Therefore, any specimens that, after genitalic examination, are not found to agree with the descriptions and figures should be sent to specialists for examination.

Though this work will become out of date as a result of new discoveries, it includes the vast majority of species likely to be found in general collecting or in field work on economic projects; for the material on which the study was based was collected largely in these ways and the collections made in recent years rarely included specimens new to the country.
