  Using data recorded with the Belle detector, we observe a new excited
hyperon, an $\Omega^{*-}$ candidate decaying into $\Xi^0K^-$ and $\Xi^-K^0_S$
with a mass of $2012.4\pm0.7\ {\rm (stat)\pm\ 0.6\ (\rm syst)}\ {\rm MeV}/c^2$
and a width of $\Gamma=6.4^{+2.5}_{-2.0}\ {\rm(stat)}\pm1.6\ {\rm(syst)}\ {\rm
MeV}$. The $\Omega^{*-}$ is seen primarily in $\Upsilon(1S), \Upsilon(2S)$, and
$\Upsilon(3S)$ decays.
