This entry initially baffled Adler, who confined herself to reporting that it appears only in ms F. But in her consolidated addenda and corrigenda she pointed out (following Maas) that the quotation here is an approximation of what Dionysus says -- about fetching Euripides from the underworld -- in Aristophanes, Frogs 68: k'oudei/s ge m' a)\n pei/seien a)nqrw/pwn to\ mh\ ou)k e)lqei=n e)p' e)kei=non. See web address 1.
The point of the lexicographer's comment is then obscured by the several possible senses of the noun diairesis. Grammatical? (But k'oudei/s is crasis, not diairesis.) I tentatively construe diairesis as hairesis, "choice", i.e. an (erroneous) attempt to gloss Dionysus' "him".
For Sophocles see generally sigma 815; for Euripides, epsilon 3695.
