      The grouse locusts (Tetrigidae) represent a group of small sized Caeliferan Orthoptera. These are considered to be primitive orthopterans related to Tridactylids on one hand to Acridids on the other. This family is represented in Indian subcontinent by about 90 species belonging to 35 genera. In the present study haemolymph protein profiles from 7 species from this family have been studied as an additional parameter to understand interrelationship amongst them. It is noted that the speciesParatettix dorsifer andEuparatettix personatus belonging to the same subfamily Tetriginae show remarkable similarity in the haemolymph protein profile, thus justifying their classical taxonomical grouping. In case of subfamily Scelimeninae, however, of the 4 species studied 3 species vizEucriotettix flavopictus, Criotettix latifrons andThoradonta pruthii show a marked similarity, howeverEucriotettix harpago shows a pattern closer to that observed in the subfamily Cladonotinae. This implies that though by classical taxonomic criteria the 4 species are close to each other this may not be a very natural grouping.

      From this observation it becomes clear that help from additional parameters like protein profile studies, immunochemical studies, cytogenetic analysis, etc will prove to be very valuable for the real understanding of phylogenetic interrelations and evolution of this family in particular and the status of grouse locusts vis-a-vis the orthopteran insects in general.
