ABSTRACT.-The subfamily Pteroplistinae (Gryllidae) is expanded to include members of the subfamily Landrevinae of Gorochov. The subfamily, which is restricted to southeast Asia and the western Pacific region as far as Fiji, is now comprised of two tribes (Pteroplistini and Lan-drevini), 29 genera and 73 species. Here 13 new genera and 31 new species are described. Evidence is given of a close relationship between the subfamilies Pteroplistinae and Oecanthi-nae. [Biogeography, crickets, Gryllidae, Landrevinae, Oecanthinae, new genera, new species, Pteroplistinae, western Pacific]. The present paper concerns a subfamily of large, mainly forest inhabiting crickets whose relationship to other groups has been problem-matical. The group is distributed over a large area from India to the western Pacific region and now contains 73 species distributed among two tribes and 29 genera. A chance ex-amination of a male of Pteroplistus (type ge-nus of the subfamily Pteroplistinae) in the Bishop Museum (Honolulu) has lead to some quite surprising discoveries concerning the re-lationships among several groups of crickets. The first is that the subfamily Pteroplistinae, which previously included only the genus Pteroplistus must be expanded to include th
