Passage 9.37.1
ἔδει δὲ ἄρα παυσθῆναι καὶ τὸ Ἄλμου γένος· οὐχ ὑπολείπεται γὰρ παῖδα Ὀρχομενός, καὶ οὕτως ἐς Κλύμενον τὸν Πρέσβωνος τοῦ Φρίξου περιῆλθεν ἡ ἀρχή. Κλυμένου δὲ γίνονται παῖδες, πρεσβύτατος μὲν Ἐργῖνος, ἐπὶ δὲ αὐτῷ Στράτιος καὶ Ἄρρων καὶ Πύλεος, νεώτατος δὲ Ἀζεύς. Κλύμενον μὲν ἐν τῇ ἑορτῇ τοῦ Ὀγχηστίου Ποσειδῶνος Θηβαίων φονεύουσιν ἄνδρες ἐξ ἀφορμῆς μικρᾶς ἐς ἅπαν θυμοῦ προαχθέντες· Ἐργῖνος δὲ ὁ πρεσβύτατος τῶν Κλυμένου παίδων τὴν βασιλείαν παραλαμβάνει.
Thus it was necessary that the line of Almus should also end, for Orchomenus left no child behind him, and the kingship therefore passed over to Clymenus, son of Presbon, who was the son of Phrixus. Clymenus had sons; the eldest was Erginus, next after him was Stratius, and then Arrhon and Pyleus, and the youngest was Azeus. Now, at the festival of Poseidon at Onchestus, certain Theban men slew Clymenus, having been led by an insignificant cause into great anger. Erginus, being the eldest of the sons of Clymenus, succeeded to the throne.
