Cissia is a genus of satyrid butterfly found in the Neotropic ecozone.
In the Persian Empire Cissia（Κισσία) was a very fertile district of Susiana, on the Choaspes. According to Herodotus, the inhabitants, Cissii, were a 'wild', free people, resembling the Persians in their manners.
Herodotus and other ancient Greek writers sometimes referred to the region around Susa as "Cissia", a variant of the Kassite name. However, it is not clear if Kassites were actually living in that region so late.
