"In
an instant every moving entity was electrified; and forming at once
into a ceremonial procession, the nightmare horde slithered away in
quest of the sound—goat, satyr, and aegipan, incubus, succuba, and lemur, twisted toad and shapeless elemental, dog-faced howler and silent strutter in darkness—all led by the abominable naked phosphorescent thing
that had squatted on the carved golden throne, and that now strode
insolently bearing in its arms the glassy-eyed corpse of the corpulent
old man."

"Succubus.
A devil in female form, the succubus specializes in seducing men.
Although feminine in meaning, in form this medieval Latin word, succubus, is masculine (because demons were supposedly sexless); the feminine form succuba (strumpet) is occasionally found."
