  We demonstrate sub-Doppler laser cooling and magneto-optical trapping of the
rare earth element Holmium. Atoms are loaded from an atomic beam source and
captured in six-beam $\sigma_+ - \sigma_-$ molasses using a strong $J=15/2
\leftrightarrow J=17/2$ cycling transition at $\lambda=410.5 \rm nm$. Due to
the small difference in hyperfine splittings and Land\'e $g$-factors in the
lower and upper levels of the cooling transition the MOT is self-repumped
without additional repump light, and deep sub-Doppler cooling is achieved with
the magnetic trap turned on. We measure the leakage out of the cycling
transition to metastable states and find a branching ratio $\sim 10^{-5}$ which
is adequate for state resolved measurements on hyperfine encoded qubits.
