The present paper is the result of several years' study of the genus Agrilus, and comprises all of the species found in the mainland of American north of Mexico. The task of revising the genus was undertaken because the group is an important one economically, and at the same time has been badly confused. Owing to the extreme variability of the species, erroneous identifications have been many, and the published distribution and host records are in a considerable part incorrect. Fortunately the collection of the United States National Museum, upon which this work is largely based, is rich in reared series of many of the species. On hundred and seventeen species and 8 subspecies or varieties are treated in this paper, of which 27 species and 2 subspecies are described as new.
