We present evidence for the production of Ξ· −, Ξ − in e +e − annihilation into hadrons. Our measurements yields: 0.026 ± 0.008 (stat.) ± 0.009 (syst.) Ξ −, Ξ − per hadronic event at W ∼ 34 GeV. Using our previous measurements of Λ, Λ and p, p production we obtain the relative yields (Ξ −, Ξ − /(Λ, Λ = 0.087 ± 0.03 ( stat.) ± 0.03 ( syst.) and (Ξ −, Ξ − /( p, p = 0.033 ± 0.011 ( stat.) ± 0.011 ( syst.) .
