Does Anyone Know What This Bug Is?

It is about an inch long and runs very fast.  I took 2 dozen pictures of it and this was the only one that wasn’t blurred!  I’ve never seen one before.  Looks like it should have wings, but it doesn’t.  The answer? It is called a Cow Killer Ant or a Velvet Ant but it is actually a variety of wasp whose female is wingless. It is called a Cow killer Ant because of the saying that its sting is so painful that it could kill a cow!
