Abstract: In this note we prove that Kalton's interlaced graphs do not equi-coarsely embed into the James space J. This allows us to exhibit a coarse invariant for Banach spaces, namely the non equi-coarse embeddability of this family of graphs, which is very close but different from the celebrated property Q of Kalton.
