The primary headword (unglossed) is aorist passive, third person singular, of kata/gnumi. It must be quoted from somewhere; perhaps Aristophanes, Wasps 1428, though there are numerous other possibilities.
[1] Perfect participle (active form with passive sense) of the same verb (cf. kappa 903), neuter nominative/accusative plural (rather than masculine accusative singular, as the glossing shows). Same or similar glossing in other lexica; see the references at Photius kappa406 Theodoridis. Again, it must be quoted from somewhere: perhaps directly from a fragment of Damascius which the Suda quotes several times (kappa 903, omega 258, tau 100), but that passage itself surely derives from a boxing metaphor used by Plato (Gorgias 515E and 524C, Protagoras 342B).
