An analytical calculation of non-relativistic flux-tube model decay amplitudes is performed in an harmonic oscillator approximation. Specific decay signatures of all $J^{PC}$ charmonium hybrids are identified and the widths predicted. We introduce a new selection rule which can be used to understand the systematics of numerical decay calculations.3 pages, LaTeX, to appear in the Proceedings of 'Quark Confinement and the Hadron Spectrum', June 20-23, 1994, Como, Italy, 0 figures, 19 kbHigh Energy Physics - Phenomenologytext
