    The lifetimes of the B - and B̄ 0 mesons are measured using the partially reconstructed semileptonic decays B̄ → Dl - v̄X, where D 0 is either a D 0 or D* + meson. The data were collected by the CDF detector at the Fermilab Tevatron collider during 1992-1995 and correspond to about 110 pb -1 of pp collisions at √s = 1.8 TeV. We measure decay lengths and extract the lifetimes to be τ(B - ) = 1.637±0.058 -0.043 +0.045 ps and τ(B̄ 0 ) = 1.474±0.039 -0.051 +0.052 ps, and the ratio of the lifetimes to be τ(B - )/τ(B̄ 0 ) = 1.110±0.056 -0.030+0.033 , where the first uncertainties are statistical and the second are systematic.
