  We present deep integrated-light spectroscopy of nine M33 globular clusters
taken with the Hectospec instrument at the MMT Observatory. Based on our
spectroscopy and previous deep color-magnitude diagrams obtained with
HST/WFPC2, we present evidence for the presence of a genuine intermediate-age
globular cluster in M33. The analysis of Lick line indices indicates that all
globular clusters are metal-poor ([Z/H] <~ -1.0) and that cluster M33-C38 is
about 5-8 Gyr younger than the rest of the sample M33 star clusters. We find no
evidence for a population of blue horizontal branch stars in the CMD of
M33-C38, which rules out the possibility of an artificially young spectroscopic
age due to the presence of hot stars. We infer a total mass of 5-9 x 10^4 M_sol
for M33-C38, which implies that M33-C38 has survived ~2-3 times longer than
some dynamical evolution model predictions for star clusters in M33, although
it is not yet clear to which dynamical component of M33 - thin disk, thick
disk, halo - the cluster is associated.
