Abstract
IUE spectra of the Beryllium II region are presented for two Lithium-r ich giant stars, HD 9746 and KD 112127. In either spectrum there is no sign of significant Beryllium features at the Be II lines 3130.416 An gstrom or 3131.064 Angstrom, which seems to indicate that Be was deple ted in these two Lithium-rich giants. This suggests that some addition al Lithium was produced in their stellar interiors during the evolutio n along the giant branch.
