Armasia
Armasia: One of several demons said to be ruled by the arch-fiend Beelzebub in the Sacred Magic of Abramelin the Mage. In the fifteenth-century French manuscript sourced by Mathers, the demon's name is spelled Amatia. Mathers suggests that this is derived from a Greek word meaning “ignorance.”
