Summary: We have obtained and presented spatially homogeneous Bianchi types II, VIII, and IX string cosmological models with bulk viscosity in a theory of gravitation proposed by \textit{D. K. Sen} [Z. Phys. 149, 311--323 (1957; Zbl 0078.19501)] based on Lyra's geometry [\textit{G. Lyra}, Math. Z. 54, 52--64 (1951; Zbl 0042.15902)]. It is observed that only vacuum cosmological model exists in case of Bianchi type IX universe. Some physical and geometrical properties of the models are also discussed.
