Using 12.7fb-1 of data collected with the CLEO detector at CESR, we observed two-photon production of the cc− states χc0 and χc2 in their decay to Π+Π-Π+Π-. We measured Γγγ(χc)×B(χc→Π+Π-Π+Π-) to be 75·13(stat)·8(syst)eV for the χc0 and 6.4·1.8(stat)·0.8(syst)eV for the χc2, implying γγγ(χc0)=3.76·0.65(stat)·0.41(syst)·1.69(br)keV and Γγγ(χc2)=0.53·0.15(stat)·0.06(syst)·0.22(br)keV. Also, cancellation of dominant experimental and theoretical uncertainties permits a precise comparison of Γγγ(χc0)/Γγγ(χc2), evaluated to be7.4·2.4(stat)·0.5(syst)·0.9(br), with QCD-based predictions
