by Lea, in the autlior's collection. The two latter 

 specimens are slightly smaller but agree in other respects 

 with the foregoing description. 



This species resembles Tetrix ornata, Say, inhabiting 

 North America. 



2rt. T. longipennis nvutahilis, form nov. 



There is a small short-wing form of longipennis from tlie same 

 localities, which may be given the appellation above noted. It is 

 similar to the preceding form, the body bearing elytra but having the 

 pronotal process and wings abbreviated, not or barely reaching to the 

 apices of the posterior femora. 



Entire length of the body, male and female, 7-8 mm.; pronotum 

 6 '5-7 '8 mm. ; posterior femora 4*8-5 mm. 



Nine adults and three larvae from Adelaide, Australia, in 

 the University Museum, Oxford. 



Eight examples from Victoria, Australia, in the author's 

 collection. 



The form mutahilis is nearly allied to priscns, Bol., and 

 may possibly be that species, but if so, Bolivar must have 

 described his species from an immature example.

 Museum, Oxford. 



This species was originally described from Ceylon ex- 

 amples. The head is more compresso-elevated than in 

 Tetrix cuspidata, Hancock, from Java. The exserted head 

 and elevation of the vertex toward the front allies this 

 species with Ewparatcttir, yet other characters are peculiar 

 also to both Tetrix and Paratettix.
