Do you know what kind of bug this is?

It's fall, and I've been having problems with these bugs that are invading my house. They're a flying insect that's shaped like a box elder bug, but it's bigger, and when you pick it up to dispose of it, it sprays a foul smelling liquid with a strong vinegary smell. I looked up "stink bugs", but the pictures don't look anything like what I have. They look like some sort of mutant box elder bug, with brown and tan markings instead of red and black.
