Likewise or similarly in other lexica, including Apollonius' Homeric Lexicon (see the references at Photius lambda152 Theodoridis), and in a scholion on Homer, Iliad 3.152, where leirio/essan is applied figuratively to the sound of cicadas. The present headword leirio/enta comes from 13.830, where Hector uses it contemptuously of Ajax's lily-white skin. Compression of earlier versions of the entry -- see esp. those of Apollonius and Hesychius -- has produced grammatical confusion in the later ones.
