  We discuss the allowed decays of a hybrid meson in the heavy quark limit. We
deduce that an important decay will be into a heavy quark non-hybrid state and
a light quark meson, in other words, the de-excitation of an excited gluonic
string by emission of a light quark-antiquark pair.
  We discuss the study of hadronic decays from the lattice in the heavy quark
limit and apply this approach to explore the transitions from a spin-exotic
hybrid to $\chi_b \eta$ and $\chi_b S$ where $S$ is a scalar meson. We obtain a
signal for the transition emitting a scalar meson and we discuss the
phenomenological implications.
