We propose that the newly discovered psi mesons lie on C = -1 partners of the daughter trajectories of the Pomeron. Consequently we consider them as excited closed string or ring states of dual or non-Abelian gauge theories. We obtain the mass formula m/subn/ $sup 2$ = 4n/$alpha$' for the spin 1 daughters of the Pomeron in terms of the universal Regge slope $alpha$' approx. = 0.85 GeV$sup -2$, and note that no new mass scale is needed to account for the psi masses (m/sub psi/ approx. = m$sub 2$, m/sub psi//sub prime/ approx. = m$sub 3$). Our model requires a new symmetry group such as color to account for the narrow width of the observed psi's. However, the zero quark content of the ring states and the weakness of Pomeron couplings gives further suppression to psi photoproduction, hadronic psi production, and some decay modes.
