  We present the first measurement of a new correlation function of Fermion
bilinears in finite temperature QCD with and without dynamical quarks in a
quantum number channel in which non-trivial correlations are known to be
present for purely gluonic operators. We find that the Fermion correlator
vanishes for $T \ge 3T_c/2$, in agreement with the expectation for weakly
interacting quarks in a quark-gluon plasma.
