Synthetic spectra of Arcturus computed with the latest theoretical stellar atmospheres disagree strongly with both the spectral energy distribution and with the spectroscopic data for $\lambda < 4000$ \AA , even though the stellar parameters are well constrained. We find that the discrepancy can be removed by adding a continuous absorption opacity that is approximately equal to that which is already included in the {\sc atlas9} code. Spectroscopy of other K2 III stars shows that the spectrum of Arcturus in not anomalous. Therefore, missing opacity may be a common feature of the models for stars in this temperature and luminosity range.
