Charmonium production in 190 GeV/c ..pi../sup -/-Be interactions has been observed. The states chi(3510) and chi(3555) are seen through their radiative decay into J/Psi, and are found to correspond to 0.29 +- 0.09 of total J/Psi production for J/Psi's with x/sub f/ > 0.2. The rate of production for the two chi states appears as Bsigma(chi(3555))/Bsigma(chi(3510) = 0.60 +- 0.35. The fraction of J/Psi's produced through chi decay appears to rise with higher x/sub f/. For J/Psi's with x/sub f/ > 0.42, chi decay is responsible for 0.345 +- 0.09 of the total J/Psi sample, with the two states produced at the rate Bsigma(chi(3555))/Bsigma(3510) = 0.82 +- 0.45.
