Habitat. — This widely distributed South American locust is repre- 

 sented by a large number of specimens of both sexes. Some of the 

 localities are: Morro do Para, Bahia; Alcobaca, Rio Tocantins in 

 Grao Para; Santa Rita, Lagoa de Rio Preto, Bahia, in Brazil; and 

 Santa Fe de la Sierra, Puerto Suarez, and Villa Bella, in Bolivia. 



This locust is aquatic in habit, as attested by its dilated hind tibiae, 

 and by the fact that it is only taken near the water. It is drawn to 

 lights at night, where it is most readily collected. 



Family OMMFXYCHID.E. 

 The locusts belonging to this family are all confined to the South 

 American continent, with their center of distribution pretty well to 

 the southward. Forms occur from the eastern slopes of the Andes 

 Mountains in Peru and Bolivia to the Atlantic and from the Amazon 

 River in the north to at least as far southward as the Rio Negro and 

 Bahia Blanca in Argentina. The genus Ossa Giglio-Tos, replaced by 

 Parossa Bruner (Ann. Carnegie Mus., VIII, p. 38, 1911) is an 

 aberrant form with smooth pronotum, and in which the wings are 

 fully developed and transparent. All of the others, so far as known, 

 the thorax strongly spined or tuberculate and generally with
