The present publication is the result of several years study of Actenodes and Chrysobothris and comprises all the species of these genera found in the mainland of America, north of Mexico, but including Lower California, the fauna of which is very similar to that of the desert regions of the Southwestern States.

Excerpt from A Revision of the North American Species of Buprestid Beetles Belonging to the Tribe Chrysobothrini Front of head narrowed at the antennae, which are inserted on the front at a considerable distance from the eyes, in rounded cavities in Oblique depres sions. Antenna with third segment distinctly longer than fourth, the sensory pores concentrated in foveae at external margin of segments. Mentum corneous at base, membranous at apex. Eyes Oblique, strongly converging toward occiput. Each elytron rounded or angulated at base, covering base Of pronotum, which thus seems lobed. Scutellum triangular, or elongate and strongly acuminate at apex. Sternal cavity formed at bottom by metasternum, and at Sides by mesosternum; metasternal epimeron partially covered by lateral prolongations Of abdomen. Prosternal process acutely angulated on each side behind coxa, and also acute at apex. Mesosternum large, narrowly divided. Posterior coxa broader internally; anterior margin straight or sinuate; posterior margin Oblique. Anterior femur toothed or unarmed.

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.
