= Synagoge epsilon754; Photius, Lexicon epsilon1750; and the derivative entry in ps.-Zonaras.
The headword is third person singular, present indicative middle, of the verb e)pite/llw. Given the glossing, this must be LSJ's e)pite/llw (A); cf. epsilon 2676. (B commonly describes the rising of stars etc.; cf. epsilon 2675.) It must be quoted from somewhere, but all extant instances of e)pite/lletai (which begin with Hesiod, Works and Days 567) appear to stem from e)pite/llw (B), with the solitary exception of a semi-restored instance in a magical papyrus (K. Preisendanz & A. Henrichs, Papyri Graecae magicae. Die griechischen Zauberpapyri vol.1 no.3 [= P. Louvre 2391], line 228: pe/lagos siga=[n e)pit]e/lletai).
