Rosalia Alpina or is it ?.................

The harvest theme is on hold for today because of the weather , I had to help my colleague take his combine up to Cheese Foot Head along side the A 272 and while he was locking up i took a few shots of this insect/beetle , i looked it up in my book then the net and this is what i came up with Rosalia Alpina , the markings are not there like they are in the book but if it is one of those its very rare !
