Masculine nominative plural of these present participles. The headword one (specifically Attic), if quoted from somewhere in this form, might come from e.g. Lucian (Philopseudes 40) or Philostratus (Life of Apollonius 4.10); note, however, that the equivalent and earlier Hesychius lambda1471 has accusative(s), which might point to (e.g.) Plato, Republic 586C.
cf. generally lambda 851, lambda 854, lambda 869.
