Same entry in ps.-Zonaras. In Byzantine pronunciation, these two verb forms differ only in accentuation.
[1] Future indicative of dii/hmi, third person singular; evidently quoted from somewhere (but otherwise unattested).
[2] Glossed as if it were the present indicative of di/eimi (from ei)=mi "go"), but this should be di/eisi; in Hesiod, Works and Days 514, dia/hsi is from dia/hmi "blow through" (web address 1).
