Have you seen this bug?

Nick at What Would Phoebe Do? had a close encounter with a gigantic insect last week. I was excited (between shudders) to see that the evil bugs that infested the loft of the D.C. apartment I rented last summer were not just figments of my imagination. I never did figure out what exactly they were (although half a can of Raid Max will kill them, and a shoe will do if that fails). So: can you identify this bug?
