Habitat. — Specimens of this beautifully marked insect are at hand 

 from Villa Bella and Rio Mamori, Bolivia, where they were taken by 

 J. D. Haseman at the last named locality on September 20, 1909, and 

 at the first mentioned locality on October 11, 1909. 



The present writer referred this insect with doubt to Stoll's Gryllus 

 (Locusta) lincatits (Natuurl. Afbeeld. Besch. Springh., pi. XV-B> 

 fig- 57) i n a former paper (Proc. U. S. Nat. Mus., XXX, pp. 675, 676 

 (1906)). 



Genus Dichroplus Stal. 



Dichroplus Stal, Recens. Orthopt., I, p. 88 (1873); Brunner, Ann. Mus. Genova, 

 XXXIII, p. 145 (1893). For additional references see Kirby, Syn. Cat. Orthopt., 

 Ill, p. 487. 



The genus Dichroplus Stal takes the same place among South Ameri- 

 can locusts that his genus Melanoplus does among these insects in 

 North America. The representatives of both genera are the common 

 medium-sized spine-breasted grasshoppers of the meadows and open 

 country. Some of the species become destructive in both continents.
