Pkceoparia is another tropical American genus of locusts. They are 

 rather above medium in size, and all of them are strongly ferruginous 

 in coloration. They evidently inhabit the forests and live among 

 fallen leaves, or on the dead and dr\ lea\ es which cling to \ arious kinds 

 of herbage growing in such localities.

Three so-called forms, or species, of locusts are referred to the present 

 genus. They are above medium in size and at the same time quite 

 gaudily colored. The genus is confined to a region covering Para- 

 guay, northern Argentina, eastern Bolivia, and southern Brazil.

Oxya ornatissima Burmeister, Handb. Ent., II, p. 636, No. 4 (1838). 

 Adimantus ornatissima Kirby, Syn Cat. Orthopt., Ill, p. 426 (1910). 



Habitat.- — There are specimens at hand coming from St. Logoas, 

 Minas Geraes, Brazil; and Province del Sara and Santa Cruz de la 

 Sierra, Bolivia, — four males and six females, collected by J. D. 

 Haseman and J. Steinbach. 



These locusts are said to feed on sugar-cane and at times to become 

 quite destructive. 



Genus Zygoclistron Rehn. 



Zygoclistron Rehn, Ent. New.-;, XVI, p. 39 (1905); Bruner, Proc. U. S. Nat. Mus., 

 XXX, pp. 642, 666 (1906); Ib., Ann. Carngie Mus., VIII, p. S9 (1911). 



The species of Zygoclistron occur over Paraguay, southern Brazil, 

 and eastern Bolivia. As stated in a former paper (ANNALS, \ III, p. 

 99) these insects are probably partial to open forests, where they live 

 among fallen leaves, etc.
