Tetrigidae (Orthoptera) from the Indian region, lodged in the Lyman Entomological Museum of McGill University, have been studied. Two new species,Potua apteran. sp. andBolivaritettix nathanin. sp., are described. The hitherto unknown male ofEpitettix tamilusGünther 1939, and females ofCriotettix latifronsHebard 1929, andLamellitettix fletcheriHancock 1915 are also described for the first time. The following species are synonymized:Hedotettix cristatusKarny 1915, withH. punctatusHancock 1909; andThoradonta pruthiiGünther 1938, withTh. sinuataHancock 1915. In addition,Loxibolus parvispinusHancock 1912, is considered to be but a form of L.acutusHancock 1904, and the nameCoptotettix rugosus(Hancock 1904) is reinstated in place ofC. hancocki(Kirby 1910).
