Lower California, and Burke reared it from Baccharis sergiloides 

 Gray collected by G. Hofer in Sabino Canyon, Ariz. 



The sculpture on the dorsal surface of the body is rather constant, 

 but the color is more cupreous, especial h on the head and pronotum, 

 in some specimens than in others. The sides of the pronotum are 

 usually parallel and slightly sinuate at the middle, but occasionally 

 specimens are found that are widest at the middle with the sides 

 arcuately rounded. The length is from 10.5 to 13.5 mm.
