[1] Aorist infinitive of qrw/|skw. Likewise or similarly in other lexica; and see also the scholia to Oppian, Cynegetica 1.82, from where it appears to be quoted.
[2] The cognate participle, masculine nominative plural; again, evidently quoted from somewhere (perhaps Homer -- occurs three times in the Iliad -- though more probably Oppian again: Cynegetica 2.427).
cf. under upsilon 311. Adler cross-references to theta 514, but the reference should be to theta 511.
