In the original description Texas was cited as the type locality, 

 but sayi with its color varieties is widely distributed in the eastern 

 L^nited States altho usually scarce in collections. Data on the above 

 collectors' labels indicate that the species may be found most fre- 

 cjuently on oaks.

Similar to tlie typical sayi but differs in being more broadly pale or red- 

 dish ; lateral margins of pronotal disk broadly pale or reddish.
