What is "bombycites"

Bombycites oeningensis is an extinct butterfly from the Upper Miocene (5.28 - 1.61 million years ago) of Öhningen, Switzerland. It is described in 1849 from a fossil pupa by the Swiss geologist and naturalist Oswald Heer. Because neither the adult nor larval forms are known, either of which contain crucial diagnostic features, its family and superfamily placement is uncertain.
