Boutes was a Lord of Attika (in Southern Greece). Boutes joined up and became one of the Argonauts.
When the Argonauts were sailing past the Sirens, he was the only one who was unable resist the charm of their singing, swimming off to them. Aphrodite saved Butes by transferring him to Lilybaeum in Sicily, where he became her lover. Aphrodite bore Boutes a son, Eryx.

Eryx (With Aphrodite)
"After them from Cecropia came warlike Butes, son of brave Teleon, and Phalerus of the ashen spear. Alcon his father sent him forth; yet no other sons had he to care for his old age and livelihood. But him, his well-beloved and only son, he sent forth that amid bold heroes he might shine conspicuous. But Theseus, who surpassed all the sons of Erechtheus, an unseen bond kept beneath the land of Taenarus, for he had followed that path with Peirithous; assuredly both would have lightened for all the fulfilment of their toil."
- Apollonius of Rhodes, Argonautica 1.95
"As they [the Argonautoi] sailed past the Seirenes, Orpheus kept the Argonautoi in check by singing a song that offset the effect of the sisters' singing. The only one to swim off to them was Boutes, whom Aphrodite snatched up and settled at Lilybaion."
