We extend our previous surveys of properties
of spectra of signless Laplacians of graphs. Some new theorems for
the signless Laplacian eigenvalues are given. In particular, a
theorem on spectral characterization of graphs with $Q$-index not
exceeding 4 is proved. The signless Laplacian eigenvalues of
connected graphs on six vertices are given in Appendix.
