He was married to Perimede, by whom he became the father of Oeonus, Argeius, and Melas. He was a friend of Heracles, whose son Tlepolemus slew him, according to some unintentionally, and according to others in a fit of anger. (Pind. O. 7.50, &c.; Apollod. 2.8.2, 2.4.5, comp. Hom. Il. 2.663.) His tomb was shown in aftertimes at Argos. (Paus. 2.22.8; Plut. Pyrrh. 34.)
