Decarabia is a demon and, according to the Lesser Key of Solomon, a Great Marquis of Hell, or a King and Earl according to the original Latin version of the Pseudomonarchia Daemonum.

He has thirty legions of demons under his command. Decarabia knows the virtues of all herbs and precious stones, and can change into all birds and sing and fly like them before the conjurer.

He is depicted as appearing as a pentagram star, changing into a man under the conjurer's request.
