Passage 8.24.1
Ψωφῖδος δὲ οἱ μέν φασιν οἰκιστὴν γενέσθαι Ψώφιδα τὸν Ἄρρωνος τοῦ Ἐρυμάνθου τοῦ Ἀρίστα τοῦ Παρθάονος τοῦ Περιφήτου τοῦ Νυκτίμου· τοῖς δέ ἐστιν εἰρημένα θυγατέρα Ψωφῖδα εἶναι Ξάνθου τοῦ Ἐρυμάνθου τοῦ Ἀρκάδος. τάδε μὲν οὖν οὕτω κατὰ τὴν Ἀρκάδων ἐς τοὺς βασιλέας ἔχει μνήμην·
Concerning Psophis, some say that its founder was Psophis, the son of Arrhon, son of Erymanthus, son of Aristus, son of Parthaon, son of Periphetes, son of Nyctimus; others have said that Psophis was the daughter of Xanthus, the son of Erymanthus, son of Arcas. Such, then, is the tradition preserved among the Arcadians concerning their kings.
