The headword, evidently extracted from somewhere, is a masculine noun (LSJ s.v. o)kri/bas, -antos) in the accusative plural. It is possibly generated by Plato, Symposium 194B (web address 1), where it occurs in the accusative singular o)kri/banta, or from the corresponding scholion; cf. omicron 123 and omicron 122. However, the gloss -- see next note -- might point to another source.
[1] Same or very similar glossing in other lexica (references at Photius omicron186 Theodoridis) i.e. with the accusative plural of the masculine noun e)mba/ths, -ou, a type of footwear; LSJ s.v. (I) finds it in two closely-related such senses, "a kind of half-boot of felt" and a synomym for the kothornos, kappa 1909. (In Hesychius omicron486 the gloss is e)nba/tas (sic), a form attested nowhere else.)
