by Lea, in the author'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. 



2rr. T. longipennis mutahilis, form nov. 



There is a small short-wing form of longipennis froin the 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, naale 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 priscus, BoL, and 

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

 described his species from an immature example.

 = Paratcttix variegaius, Bolivar. 



Two female examples from Java referable to this species. 

 Example No. 9332 from East Java, Montes Tengger, 

 4000 ft. ; presented by Malcolm Burr to the University 

 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 Euparatettkv, yet other characters are peculiar 

 also to both Tetrix and Paratcttix. 



4. T. ornata, Say, Ent. i, p. 137, Plate V, 1824. 



One male and one female example from America ; one 

 from " U. S."; W. W. Saunders' collection, presented by 

 Mrs. F. W. Hope to the University Museum, Oxford.
