The headword, evidently extracted from somewhere, serves as the aorist active infinitive of the verb blw/skw, I go, I come; see LSJ s.v., and other forms at mu 1200 and mu 1202. The aorist form derives from the verb's root stem, mol-; the present stem comes from mlo-: see Cunliffe s.v. blw/skw.
[1] The gloss is the aorist active infinitive of the verb e)/rxomai, I go, I come; see LSJ s.v. The headword is identically glossed in the Synagoge, Photius' Lexicon (mu507 Theodoridis), and Lexica Segueriana 303.1; cf. Hesychius s.v. and De Stefani, p. 63.
