(Ἱάρβας), a king of the Numidians, who supported Domitius Ahenobarbus and the remains of the Marian party in Africa. It seems probable that he was established on the throne by Domitius, in the place of Hiempsal, who had given offence to Marius. On the arrival of Pompey in Africa (B. C. 81), Hiarbas supported Domitius with a large force, and shared in his defeat : after which he fell into the conqueror's hands, and was put to death. (Plut. Pomp. 12; Liv. Epit. lxxxix.; Oros. 5.21; Entrop. 5.9.) The name is very variously written, but the above is probably the most correct forin.
