In Greek mythology, the Furies or Erinyes; goddesses of vengeance and justice who punished wrongdoers; also the plural of eumenid wasps.
From Greek 'eu' (good/kindly) + 'menos' (mind), a euphemistic name for the Erinyes (Furies) to appease them; used today for both mythological figures and the wasp family.
The ancient Greeks actually renamed the Furies from 'Erinyes' (anger goddesses) to 'Eumenides' (kind-minded ones) out of sheer fear—it's one of history's most clever examples of trying to appease supernatural beings through flattery.
