Thelxion of Argos
In Greek mythology, Thelxion is the companion of Telchin. Along with his companion, he planned a conspiracy against Apis, the son of Phoroneus, and finally the two killed him. They were in turn slain by Argus Panoptes
It has been suggested that Thelxion was a son of Europs and thus a brother of Telchin.Note
