Stheneboea was the wife of Proëtus who failed to seduce Bellerophon and so tried to bring about his death. When she failed she committed suicide (although according to Euripides, Bellerophon killed her). Homer calls her Antia. Her name is a propitious one, meaning 'strength of cattle', from sthenos, 'strength', 'might' and bous, 'ox'.
