Ilahitat. — Sapucay, Paraguay, 2 males and 1 female. 



This insect's relationship to its allies may be seen by a reference to 

 the accompanying synoptic table. Whether or not emarginata Stal 

 and omnlcolor Blanchard are distinct, I am unal^le to say. 



ZONIOPODA EMARGINATA Stal. 

 Zoniopoda emarginata Stal, Recens. Orthopt., I, 1873, p. 52. 



Habitat. — Stal gives Brazil as the habitat, while Pictet and Saussure 

 simply say "Amerique meridionale." 



Whether or not this species is distinct from oriinlcoloi' Blanchard, 1 

 am unable to say. If it is, it ma}- also be looked for in Paraguay. 



ZONIOPODA OMNICOLOR (Blanchard).

 Zoniopoda omnicolor Bruner, Locusts of Argent., 1900, p. HI, fig. 27. 



Ilahitat. — Several specimens are at hand from Sapucay, Paraguay. 

 They were taken by W. T. Foster. It is also reported by Giglio-Tos 

 and Rehn as a Paraguayan insect. 



This species occurs rather commonly at Cordo])a, in Argentina, 

 where it is found in colonies upon special food plants, after the manner 

 of Chrornacrh stolli. 



ZONIOPODA PICTA Bolivar. 



Zoniopoda pi da Bolivar, Viaje Pacif., Orthopt., 188-1, p. 37. 



Ilahitat. — If the writer has rightfully determined this insect, it may 

 also be found in Paraguay. It is not reported from tliat country by 

 the authors already referred to in connection with the preceding- 

 species. 



TROPIDACRIS Scudder. 



TROPIDACRIS DUX (Drury)? 



GryJhis dax Drn'RV, Illustr. Nat. Hist., II, 1837, new e<l., jil. xliv. 



Ilahitat. — Giglio-Tos refers to this insect as being found at Asun- 

 cion, Paraguay. It is not represented in any of the collections at 

 hand.
