Likewise in other lexica, notably Synagoge upsilon43 and Photius upsilon77 Theodoridis. The headword is neuter plural of this adjective, presumably quoted from somewhere; perhaps Diogenes Laertius 3.105, where it occurs three times in a description of Platonic doctrine. (It is certainly a philosophical term: see also e.g. Divisiones Aristoteleae 35 col. 1.11-13.)
