I think the previous posters are on the right track (a type of Long-horned Beetle). It probably isn't
Prionus coriaceus (now
P. coriarius?) because that's a European species, but there are several
Prionus sp. in North Carolina (see
http://bugguide.net/node/view/3142). Hardwood Stump Borer is also a type of Long-horned Beetle and it does live in North Carolina.
Since you live in North America, you might consider posting the image to
bugguide.net (you'll have to create an account if you don't have one). Post it to the lowest certain place in the taxonomy, e.g., Beetles. Expert reviewers will help you with a more specific ID.
