Guid.Parse() or new Guid() - What's the difference?

What is the difference between these two ways of converting a string to System.Guid? Is there a reason to choose one over the other?

var myguid = Guid.Parse("9546482E-887A-4CAB-A403-AD9C326FFDA5");

or

var myguid = new Guid("9546482E-887A-4CAB-A403-AD9C326FFDA5");
