We search for pair production of doubly charged Higgs particles ( $H^{\pm \pm}$ ) followed by decays into electron-tau (etau) and muon-tau (mu tau) pairs using data (350 pb-1) collected from $\bar{p} p$ collisions at $\sqrt{s} = 1.96$ TeV by the CDF II experiment. We search separately for cases where three or four final-state leptons are detected, and combine results for exclusive decays to left-handed etau (\mu tau) pairs. We set an $H^{\pm \pm}$ lower mass limit of 114(112) GeV/c2 at the 95% confidence level.
