Passage 9.36.1
γενομένης δὲ Ἐτεοκλεῖ τῆς τελευτῆς ἡ βασιλεία περιῆλθεν ἐς τὸ Ἄλμου γένος. Ἄλμῳ δὲ αὐτῷ μὲν θυγατέρες Χρυσογένεια ἐγένετο καὶ Χρύση· Χρύσης δὲ τῆς Ἄλμου καὶ Ἄρεως ἔχει φήμη γενέσθαι Φλεγύαν, καὶ τὴν ἀρχὴν τὴν Ἐτεοκλέους ἀποθανόντος ἄπαιδος ὁ Φλεγύας ἔσχεν οὗτος. τῇ μὲν δὴ χώρᾳ τῇ πάσῃ Φλεγυαντίδα ὄνομα εἶναι μετέθεντο ἀντὶ Ἀνδρηίδος,
Upon the death of Eteocles, the kingdom passed into the family of Almus. Almus himself had daughters named Chrysogeneia and Chryse. It is said that Chryse, daughter of Almus, bore a son, Phlegyas, by Ares. After Eteocles died without issue, Phlegyas succeeded to his throne. Afterward, the inhabitants renamed the entire region Phlegyantis instead of Andreis.
