Photius, Lexicon s.v. has the same entry, and for a variant see Hesychius, Lexicon delta1471: *diayai/rousi: diapne/ousi. kai\ yai/rein ga\r le/gomen to\ i(sti/on, o(/tan e)lafrw=s diapne/htai; "they brush away: they blow away. And we say 'to brush the sail', when the wind is blowing gently through”. The primary source is probably a scholion to Aristophanes, Birds 1717, where diayai/rousi is used when the poet is caricaturing Euripides’ language (see fr. 926 Nauck).
