Same entry in Photius (and ps.-Zonaras). The headword as transmitted is the accusative singular of a feminine noun di/ecis, but LSJ recognises no such noun, and Theodoridis in his Photius edition obelizes it, proposing that one should read instead di/icin. For this see a later entry in Photius, delta580, where nominative di/icis is glossed with diece/leusis.
The accusative di/icin occurs in several ancient commentators on philosophy (e.g. Simplicius and Proclus).
