Harpalyce was the name of a daughter of Clymenus, king of Argos (who abducted her when she married Alastor), and of a daughter of Harpalycus, a Thracian king. The second Harpalyce clearly gets her name from her father.
The first was involved in a violent situation - before she married Alastor, Harpalyce's father had incestuously raped her, and after he abducted her, she murdered the child she bore him - and this may explain her name which means 'ravening wolf, from harpazo, 'to ravish', 'abduct' and lycos, 'wolf. (The name refers to her father's acts: compare Halirrhothius, whose name similarly relates to his father.)
