Is this C. wislizeni or another species? It was scampering in a wash in the Chihuahuan Desert of the Big Bend Region. I have seen others in the Mojave Desert of California with powdery white instead of the metalic purple.

Just wanted to compliment Matthew on his images, and welcome him to Bugguide if no one else has already done so. Thank you for sharing your work. You are making many fine contributions here.

Thank you very much
I appreciate your welcome and want to thank everyone responsible for making Bugguide possible. I have been seeing unusual insects for years but this site has become a wonderful aid to my studies. My first digital camera is what is making these pictures possible.

Should be wislizeni
Found from Texas to AZ, the other one is restricted to California (maybe western AZ).
