A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 209 



DISTRIBUTION 



From material examined : 



Arizona: Sabino Canyon, reared (G. Hofer). Santa Catalina Mountains, reared 

 CM. Chrisman) ; August 12, 1914 (B. R. Coad). San Bernardino Ranch, 

 Cochise County, 3,700 feet, August 9-18, 1905 (E. G. Smyth, F. H. Snow). 

 Redington, 1915 (M. Chrisman). Santa Rita Mountains (D. K. Duncan). 



Mexico: Sonora, types (Arthur Schott). 



Also recorded in the literature by Chamberlin (1926) as follows: 



Arizona: Douglas, Pinal Mountains, and Yuma. 

 New Mexico : No definite locality. 



LeConte (1858) described the species from two females collected 

 by Arthur Schott in Sonora, Mexico, but in his Revision of the 

 Buprestidae (1859) he states that the two specimens were collected by 

 Mr. Schott in Arizona. 



Hosts. — The adults have been reared from mesquite (Prosopis 

 jvZiflora (Swartz) De Candolle) collected in Sabino Canyon and the 

 Santa Catalina Mountains, Ariz., by Geo. Hofer and Mr. Chrisman. 

 Burke (1918) records it mining the bark, sapwood, and heartwood 

 of dying and dead limbs and trunks of mesquite in Arizona, and 

 reports that it may kill entire trees and cause severe injury to the 

 wood. Chamberlin (1926) records a specimen in the United States 

 National Museum bearing the label "reared from Quercus albd." 

 This specimen is erroneously labeled, and the notes show that it was 

 reared from mesquite. 



Very little variation was observed in the specimens examined,, 

 except that the foveae on the elytra vary in color from bright green 

 or golden green to reddish cupreous, and frequently the costae on 

 the elytra become obsolete in the basal regions. The length is from 

 19 to 22 mm.
