Habitat. — The only reference to this unusually large species is that 

 given by Giglio-Tos. It conies from Colonia Risso, Paraguay.

Hahitat. — Asuncion, (Bruner); Sapucay (VV. T. Foster). This insect 

 was fairly common on the sandy knolls about Asuncion. It also occurs 

 in Northern Argentina on both sides of the Rio Parana. An allied 

 species, Eu, consjyersus Bruner, is figured herewith on Plate XXXVI, 

 fig. 4.

Hahitat. — In sandy and dry localities from central Mexico to middle 

 Argentina. It may be looked for in Paraguay, and if proper locations 

 are examined it will no doubt be found. No specimens are at hand, 

 nor am I aware of its having been reported as occurring in that 

 country.

Hfhifat. — Glglio-Tos gives Asuncion and Colonia Risso, Paraguay, 

 as localities where it occurs. It is also quite generally distributed 

 over the warmer parts of South America. The variety hrevipennis 

 Giglio-Tos is also credited to Paraguay. 



This insect was made the type of a distinct subfamily by SUll; but 

 Brunner v. Wattenwyl in his Revision du Systeme des Orthopteres, 

 places it along with the CEdipodinte, where I am willing to let it 

 remain at present. The insect is one that lives upon aquatic plants 

 and often must swim, hence the peculiar development of hind tibiae 

 and their spurs.
