Graphoderus occidentalis Horn
You are correct, sir! Be on the lookout for Graphoderus perplexus. It's very common in your area as well.

Hey, this reminds me...Jim, would you contact me off-list? There are some questions I've been meaning to pose to you. Thanks. My email is listed on my profile page.
