[1] The headword is aorist passive participle, masculine nominative singular, of the same verb as lambda 424. Same glossing in Photius lambda244 Theodoridis. The earliest known instance of an aorist passive participle is the feminine accusative singular lhi+sqei=san in Apollonius Rhodius, Argonautica 4.400; the masculine form which has generated the Photius/Suda entry is also to be seen in Hesychius lambda830 (lhi+sqe/ntos glossed klape/ntos, a)faireqe/ntos).
[2] This distinction, made by Aelius Dionysius, *)attika\ o)no/mata s.v. lh|stiko/n, attempts to give an active sense to lh|stiko/n "plundering" (e.g. "of pirates") vs. lh|striko/n "plundered". This is not reflected in how lh|striko/s was actually used, however: see LSJ s.v. The instance being glossed is Thucydides 1.4; see the scholia there. Aelius Dionysius is cited more closely in Photius lambda251 Theodoridis; the distinction is also invoked in lambda 474.
