Your beetle is a Cerambycid or Long Horned Borer Beetle known as a Harlequin Beetle, Acrocinus longimanus. It is one of the largest and most magnificent members of its family. It is found in Central and South America. We held off on an identification until you provided us with a location. We wrote back requesting the location because we really wanted to post the photo.
