Passage 8.24.10
ἐπεθύμησεν ἡ Καλλιρόη τῆς Ἐριφύλης οἱ γενέσθαι τὸν ὅρμον καὶ διʼ αὐτὸ ἐς τὴν Φηγίαν τὸν Ἀλκμαίωνα ἔστειλεν ἄκοντα, καὶ αὐτὸν ὑπὸ Φηγέως τῶν παίδων Τημένου καὶ Ἀξίονος δολοφονηθέντα ἐπέλαβεν ἡ τελευτή. τοῦ Φηγέως δὲ οἱ παῖδες τῷ Ἀπόλλωνι ἀναθεῖναι τῷ ἐν Δελφοῖς λέγονται τὸν ὅρμον. καὶ ἐπὶ τούτων βασιλευόντων ἐν Φηγίᾳ τότε ἔτι καλουμένῃ τῇ πόλει Φηγίᾳ στρατεῦσαί φασιν Ἕλληνας ἐς Τροίαν· σφᾶς δὲ οἱ Ψωφίδιοι τοῦ στόλου φασὶν οὐ μετασχεῖν, ὅτι αὐτῶν τοῖς βασιλεῦσιν οἱ Ἀργείων ἀπηχθάνοντο ἡγεμόνες, κατὰ γένος τε τῷ Ἀλκμαίωνι οἱ πολλοὶ προσήκοντες καὶ τῆς ἐπιστρατείας αὐτῷ κοινωνήσαντες τῆς ἐς Θήβας.
Callirhoe desired to possess Eriphyle's necklace, and therefore sent Alcmaeon unwillingly to Phegia, where death overtook him, treacherously murdered by Phegeus' sons, Temenus and Axion. The sons of Phegeus are said to have dedicated the necklace to Apollo at Delphi. During their reign over the city then still called Phegia, the Greeks, it is said, undertook the expedition against Troy. But the people of Psophis claim that their city did not participate in this expedition, alleging that the Argive leaders bore hostility toward their own kings, since the majority were related by birth to Alcmaeon and had assisted him in his campaign against Thebes.
