Yep. They do not have the incorporeal property. So they are solid.
The fact that they are a mass of air bunched together with whatever magic wibbly wobbly stuff they have going on is represented by the fact that they can't bleed and are immune to crits. Also, DR with higher level ones.
Presumably, when it comes to smacking them, you hit their magic-y stuff, and that can be smashed up to the point they fall apart.
