This paper presents a new systematic survey of diffuse interstellar bands in the optical wavelength range from 5650 to 6865 Å based on echelle spectra of medium-reddened early-type stars acquired at McDonald Observatory. Adding up interstellar spectra of the same type (as it was done by Krełowski et al. 1997) we reached a very high signal–to–noise ratio. In this spectral range 89 new features have been discovered, 62 of them certain. In the whole spectral range of this survey we have found 240 features, 213 of them certain.
