The headword -- leleiourghme/na here, correcting leliourghme/na in Photius lambda170 Theodoridis -- is perfect middle/passive participle, neuter nominative/accusative plural, of the rare verb leiourge/w or liourge/w. It is evidently quoted from somewhere.
The participle occurs in the masculine nominative plural in Clement of Alexandria, Paedagogos 3.3.15.4, referring to men who undergo depilatory procedures.
