The scholion is composite and gives two different etymologies: in the first part, preserved both in the A scholia and the T scholia φύξηλις is analyzed as a derivative of the future of φεύγω (which in fact is φεύξομαι, not *φύξω, a ghost form invented for the sake of the explanation): derivation from the future was usual in Greek etymology, and it provides the [s]. In the latter part, preserved only in the A scholia, the word is parsed as a compound, and the second element is identified as ἀλέομαι "to flee". The structure is that of a tautological compound with two synonymous verbs. This latter part was probably added afterwards and the scholiast did not notice that the etymology was incompatible with the first one mentioned: we would expect "or from φεύγω and ἀλέομαι", the regular formulation for alternative etymologies
