females. They come from Santa Isabel, Rio Negro, Uruguay. They 

 were collected by J. D. Haseman on February 12, 1909.

Habitat. — Santa Isabel, Rio Negro, Uruguay, February 12, 1909, 

 J. D. Haseman collector. The single female at hand was in a box 

 with three specimens of Schistocera paranensis Burmeister. It bears 

 the label "by the billions, a great pest in all central southern S. 

 America this year — eats everything except leaves of coffee plant." 



The above record in connection with the present species, and that 

 referring to the following one, would tend to show that most, if not all, 

 of the South American species belonging to the genus at times increase 

 so as to become pests. Similar observations have also been made and 

 recorded concerning some of the Mexican and Central American 

 representatives of the genus. 



52. Scyllina sp.? 

 The collection made by J. D. Haseman contains also several half- 

 grown nymphs of this genus of locusts. They were taken along the 

 Rio Novo, in the province of Goyaz, Brazil. All of the specimens are 

 of the same size and appearance, being flavous and very heavily 

 marked with black. They evidently belong to 5. smithi Rehn, or a 

 closely allied form, the representatives of which vary but little in 

 size and color. Mr. Haseman states that there were "millions in 

 grass." They were taken February 4, 1908. 



53. Scyllina brunneri (Giglio-Tos). 



Pseudostauronotus brunneri Giglio-Tos, Zool. Jahrb., Syst., VIII, p. 809 (1895). 

 Pleclrolettix brunneri Bruner, Biol. Centj-Amer., Orthopt., II, p. 100 (1904); Ib., 



Proc. U. S. Nat. Mus., XXX, p. 636 (1906). 

 Scyllina brunneri Rehn, Proc. U. S. Nat. Mus., XXX, p. 385 (1906). 



Habitat. — Four males and one female taken by J. Steinbach are 

 referred to this variable species. They were collected at Santa Cruz 

 de la Sierra, Bolivia, at an elevation of 450 meters above the sea.
