Unknown Red and Black beetles

[fishman10]

I was walking the backyard yesterday trying to find something to photograph and came across these red and black beetles. There were hundreds of them in a single 1 square foot area. I have no idea what kind they are. If you have any guess let me know. Found in North Texas

Interesting bugs. I have no idea what they could be. As for the photos it looks like some of your highlights are blown out a little too much.
