As transmitted (and unparalleled elsewhere), the present active participle of the verb sfhko/w, masculine nominative plural, quoted from somewhere -- unless Bernhardy was right to emend the headword to sfhkw=nes "wasps' nests" (but that too is v.poorly attested).
cf. kappa 1349 (and, more generally, the modern concept of being 'wasp-waisted'). For wasps see also e.g. sigma 1732, sigma 1733, sigma 1741.
