We present the results of a visual spectroscopic campaign aimed at studying the properties of the Eos family members, as well as of the ``Eos fugitives''. The latter are a sample of asteroids whose peculiarity has been recently discovered by Morbidelli et al. (1995) (Icarus 118, 132-154). What makes these objects very interesting is the fact that they are located inside the 9/4 mean-motion resonance with Jupiter, and they likely originate from the Eos dynamical family. In particular, it has been shown that these objects suffer over short time-scales rapid eccentricity changes, which lead them to leave the original location of the Eos family in the proper elements space. The final fate of these objects is still a matter of debate, but it is plausible that at least a fraction of them could experience strong interactions with the internal planets. The Eos family has long be known to be composed by objects exhibiting spectroscopic properties compatible with those of CV/CO chondrites. For this reason, we have observed a number of Eos fugitives and Eos nominal members, in order to check whether the spectral properties of the fugitives are compatible with those of the family. The results show that the fugitives share the same spectral properties of the nominal Eos members. This fact confirms that the fugitives are really originating from the Eos family. Moreover, we have here a first case in which objects showing a definite spectral match with some kind of meteorites are observed while leaving their original location within the asteroid main belt.
