  Production of metastable charmonium states more massive than the $\psi(3685)$
is expected in models and could be the source of up to $50\%$ of the $\psi$
observed at large $p_T$ at the Tevatron.Narrow $2^{-+},2^{--} c\bar{c}$ are
predicted at around 3.8GeV and radially excited $2^3P_{1,2}$ may also have
suppressed hadronic widths making these states potentially extra sources of
$\psi(3685)$. Colour octet components are believed to dominate $\psi$
production at the Tevatron which suggests that hybrid charmonium production may
also be prominent. Estimates of hybrid production rates and branching ratios
into charmonium suggest that metastable hybrids with mass $\approx$ 4GeV may
play an important role in generating the observed $\psi(3685),\psi(3095)$
