Aorist passive participle(s), in the masculine nominative singular. Similar entry in other lexica, though the headword varies between qwrhxqei/s (as here) and qwraxqei/s -- a discrepancy (overlooked by Theodoridis on Photius s.v.) which hampers the search for a source. If the Suda's version is correct, perhaps from Theognis (1.508, 884).
cf. generally theta 439, theta 440, theta 441, theta 442.
