Pausanias Description of Greece 2.4.4

[4] Aletes himself and his descendants reigned for five generations to Bacchis, the son of Prumnis, and, named after him, the Bacchidae reigned for five more generations to Telestes, the son of Aristodemus. Telestes was killed in hate by Arieus and Perantas, and there were no more kings, but Prytanes (Presidents) taken from the Bacchidae and ruling for one year, until Cypselus, the son of Eetion, became tyrant and expelled the Bacchidae. ¹ Cypselus was a descendant of Melas , the son of Antasus. Melas from Gonussa above Sicyon joined the Dorians in the expedition against Corinth . When the god expressed disapproval Aletes at first ordered Melas to withdraw to other Greeks, but afterwards, mistaking the oracle, he received him as a settler.
  Such I found to be the history of the Corinthian kings.

Kypselos was a descendant of Melas, the son of Antasus. Melas from Gonoussa above Sikyon joined the Dorians in the expedition against Corinth. When the god expressed disapproval Aletes at first ordered Melas to withdraw to other Greeks, but afterwards, mistaking the oracle, he received him as a settler.
