Found this magnificent (and large) beetle in the lawn in Central Oregon. Found Sep. 2011 at 4400’ during a typical 80o fall day. It was the only one like it that we’ve seen here. My searches on other beetle sites didn’t uncover anything close,

Dear JDinOR,
This lovely beetle is a female California Root Borer, Prionus californicus, and you can see a matching photo on BugGuide.
