II., king of EPIRUS, was the son of Arymbas, and grandson of Alcctas I. On account of his ungovernable temper, he was banished by his father, who appointed his younger son, Aeacides, to succeed him. On the death of Aeacides, who was killed in a battle fought with Cassander B. C. 313, the Epirots recalled Alcetas. Cassander sent an army against hint under the command of Lyciscus, but soon after entered into an alliance with him (B. C. 312). The Epirots, incensed at the outrages of Alcetas, rose against him and put him to death, together with his two sons; on which Pyrrhus, the son of Aeacides, was placed upon the throne by his protector Glaucias, king of the Illyrians, B. C. 307. (Paus. 1.11.5; Diod. 19.88, 89 ; Plut. Pyrrh. 3.)
