5. A son of Phegeus, king of Psophis, in Arcadia. He was brother of Pronous and Arsinoe, who was married to Alcmaeon, but was abandoned by him. When Alcmaeon wanted to give the celebrated necklace and peplus of Harmonia to his second wife Calirrhoe, the daughter of Achelous, he was slain by Agenor and Pronous at the instigation of Phegeus. But when the two brothers came to Delphi, where they intended to dedicate the necklace and peplus, they were killed by Amphoterus and Acarnan, the sons of Alcmaeon and Calirrhoe. (Apollod. 3.7.5.) Pausanias (8.24.4), who relates the same story, calls the children of Phegeus, Temenus, Axion, and Alphesiboea.
