NORTH AMERICAN BUPRESTID BEETLES 193 



The types of both of these species have been studied, and no differ- 

 ences except slight variations and sexual could be found. Horn 

 (1891) has confused a number of species under this name, and the 

 specimen of " obolinus No. 3 " from Arizona in the LeConte collec- 

 tion is a specimen of politus Say, and neither of the two examples in 

 his own collection in the Philadelphia Academy of Natural Sciences 

 is obolinus LeConte. These two specimens are labeled " Tex." and 

 "Ariz." and are probably baboquivariae Fisher, but at the time these 

 specimens were examined I did not separate bdboquivariae Fisher 

 from costipennis Fisher. The specimens recorded in the literature 

 from California are probably costipennis Fisher. Chamberlin (1926) 

 records this species from Ontario, Canada, but that record refers to 

 obliqvMs LeConte instead of obolinus LeConte. 



This species resembles politus Say in general appearance, but it is 

 usually more robust, the pronotum is more or less longitudinally de- 

 pressed, and it can be separated at once from that species by the 

 scutellum not being transversely carinate.
