INTRODUCTION 



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 in- 

 cluding Lower California, the fauna of which is very similar to that 

 of the desert regions of the Southwestern States. 



The task of revising these genera was undertaken because the genus 

 Chrysobothris is an important one economically, and, although many 

 species have been described during the past 50 years, no revisional 

 study has been made of the North American species since 1886.
