This statue was apparently dedicated by Ptolemy Memphites, shortly before he was murdered by his father; see R.M.Errington, "A History of the Hellenistic World", page 297 ( Google Books ).
King Ptolemaios, son of king Ptolemaios Euergetes, dedicated this statue of queen Kleopatra Euergetis, the wife of my father and also my cousin, on account of my gratitude towards her, to Apollo, Artemis and Leto.
