NORTH AMERICAN BUPRESTID BEETLES 325 



Texas: Montell, April 2, 1907 (W. F. Fiske). Zavalla County, April (Hunter 

 and Pratt). Victoria, April 9, 1916 (J. D. Mitchell). 



Vibginia: Dyke, May 28, 1920 (L. L. Buchanan). Pennington Gap, July (Hub- 

 bard and Schwarz). 



West Virginia : No definite locality. 



Variations. — The color varies from brownish cupreous to bluish 

 green, but is usually dark bronzy brown. The lateral margins and 

 median depressions on the pronotum, the anterior margin of the 

 prosternal lobe, and the length of the posterior tarsi are all more or 

 less variable, and can not be used satisfactorily in this species. 

 Length, 3.25 to 5.25 millimeters. 



Host. — This species has been reared a number of times from dead 

 branches of hackberry {Geltis ocddentalis Linnaeus), and is common 

 wherever its host plant occurs. 



This is a perfectly good species, but so far, no valid characters 

 have been found for separating the females of this species and egenus 

 satisfactorily, although a large series of reared specimens of both 

 species were available for study. The external characters in the males 

 are also variable, but in celti the males have the sides of the genitalia 

 nearly parallel to each other, and the species lives in hackberry, 

 whereas in egenus the sides of the genitalia are strongly expanded 

 near the apex, and the species lives in black locust.
