Stephanos of Byzantium - Ethnika
Panhellenes: as in 'Panachaioi', the whole named from a part, as in the poet, '[to] slay Leleges and Trojans'. For in his usage the 'Hellenes' are those who inhabit Phthiotic Hellas: 'and they were called Myrmidons and Hellenes and Achaioi'.

…νας καὶ τὴν Κεφαλληνίαν ἐν δυσὶ 'λλ'—πλὴν τοῦ περπέρην.

Ἕλληνες γὰρ παρ´ αὐτῷ οἱ τὴν Φθιῶτιν Ἑλλάδα κατοικοῦντες «Μυρμιδόνες δὲ καλεῦνται καὶ Ἕλληνες καὶ Ἀχαιοί» (Il. 2, 684), εἴρην μελλείρην, ποιμήν ἀρχιποίμην, αὐχήν ἐριαύχην, ῥήν πολύρρην παρὰ τῷ τὰ Ναυπακτικὰ ποιήσαντι·
