COLY´ERGIA(Κωλυεργία), a promontory of Argolis, placed by Pausanias (Paus. 2.34.8) between Bucephala and Buporthmus; but as there are no promontories on this coast, Leake conjectures that Colyergia may have been the eastern cape of the island of Hydreia. ( Peloponnesiaca, p. 285, seq.; comp. Boblaye, Recherches, &c., p. 60.)
