What does 'laminoe' as used by Gene Wolfe in Peace mean?

Does anyone know what a ‘laminoe’ is, as used by Gene Wolfe in Peace?

"And as if by magic – and it may have been magic, for I believe America is the land of magic, and that we, we now past Americans, were once the magical people of it, waiting now to stand to some unguessable generation of the future as the nameless pre-Mycenaean tribes did to the Greeks, ready, at a word, each of us now, to flit piping through groves ungrown, our women ready to haunt as laminoe the rose-red ruins of Chicago and Indianapolis when they are little more than earthen mounds, when the heads of the trees are higher than the hundred-and-twenty-fifth floor – it seemed to me that I found myself in bed again, the old house swaying in silence as though it were moored to the universe by only the thread of smoke from the stove."

It sounds like some kind of ghost, but just curious where he might have got this word from and its exact meaning, if it has one.
