Lithodryas

Lithodryas is a prehistoric genus of butterflies in the family Lycaenidae^[1]. It was introduced as a replacement for Samuel Hubbard Scudder's genus Lithopsyche, which is invalid as a homonym, as another fossil lepidopteran genus had been described under the same name shortly before Scudder established his genus.
