Basement bugs

We see a lot of multi-limbed visitors in our house, but I'm under standing orders to murder most of them on sight. A beautiful gigantic spider had to go un-photographed after he startled my wife at the bottom of the stairs. This lucky bugger got a few minutes' respite since I found him when she wasn't around to demand an immediate execution. After the portrait session was over, he got a one-way ticket on the toilet express.

Only one question remains, and I pose the challenge to any amateur entomologists who might be reading. What's this bug?
