1. A daughter of Cadmus and Harmonia, was the wife of Aristaeus, by whom she became the mother of Polydorus. (Hesiod. Theog. 977; Paus. x. 17. § 3.) According to Apollodorus (iii. 4. § 2, &c.), Polydorus was a brother of Autonoë, and Actaeon was her son. (Comp. Diod. iv. 81.) Autonoë together with her sister Agave tore Pentheus to pieces in their Bacchic fury. (Hygin. Fab. 184.) At last grief and sadness at the lamentable fate of the house of her father induced her to quit Thebes, and she went to Erineia in the territory of Megara, where her tomb was shewn as late as the time of Pausanias. (i. 44. § 8.)

2. There are five other mythical personages of this name. (Hesiod. Theog. 258 ; Apollod. i. 2. § 7, ii. 1. § 5, 7. § 8; Paus. viii. 9. § 2; Hom. Od. xviii. 182.)
