What is the large beetle with a tan shell and golden head?

It is probably Pelidnota Punctata, the spotted tan beetle, also known as the Grapevine Beetle because that is where it frequently feeds. For a good picture see:' http://bugguide.net/node/view/12597/bgimage Distinctive is its color, the 3 or 4 spots along its side, and where it is frequently found feeding (grapevines).
