λέγειν, κατηγορεῖν: indir. disc. for impf. indicative. The κατηγορία proper begins with ἃ δή. The use of δή implies a fact beyond controversy.
οὑτοσὶ ἀνήρ: Callicles with this turns to the surrounding listeners to give vent to his indignation. Cf. 467 b, 505 c.
οὐ παύσεται φλυαρῶν: Callicles, who looks upon all philosophical activity as φλυαρία, objects to having dialectical treatment applied to him.
εἰπέ μοι: the asyndeton renders the question especially incisive, and hence is a measure of excitement. The question οὐκ αἰσχύνει is a rhetorical imperative.
2 f.
ὀνόματα θηρεύων: the same image is employed in Theaet. 166 c, with the substantive ὀνομάτων θήρευσις to denote logomachy, where the matter at issue has been quite forgotten.
