The quasiparticle interference (QPI) patterns in BiS$_{ 2}$-based superconductors are theoretically investigated by taking into account the spin-orbital coupling and assuming the recently proposed $d^{ *}_{ x^{ 2}-y^{ 2}}$-wave pairing symmetry. We found two distinct scattering wave vectors whose evolution can be explained based on the evolution of the constant-energy contours. The QPI spectra presented in this paper can thus be compared with future scanning tunneling microscopy experiments to test whether the pairing symmetry is $d^{ *}_{ x^{ 2}-y^{ 2}}$-wave in BiS$_{ 2}$-based superconductors.
