In demonology Decarabia is given no title in the hellish hierarchy, according to Pseudomonarchia Daemonum, but to The Lesser Key of Solomon he is a Great Marquis of Hell. 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 appearing as a pentagram star, changing into a man under the conjurer's request.

Other spelling: Carabia.
