[Surinam.] 
Independencia, Parahyba. (Mann and Heath.) Three fe- 
males. 
These specimens have been compared with two topotypic 
females (Paramaribo, Surinam; K. Mayo), in the collection of 
the Academy, and no differences worthy of mention seen. 
The species is widely distributed in South America, extending 
south to Argentina and west to eastern Peru and Ecuador, reach- 
ing as high as five thousand feet elevation in Peru (Huadquina; 
Caudell).

Manaos, Amazonas. (Mann and Baker.) Two males. 
Porto Velho, Rio Madeira. (IMann and Baker.) One male. 
These specimens have been recorded by Hebard in his study of 
the genus. 
Miogryllus verticalis (Serville)^^ 
1839. Gryllus verticalis Serville, Hist. Nat. Ins., Orth., p. 343. [Cayenne.] 
Baturite Mountains, Ceara. (W. M. Mann.) One male. 
Maranguape Mountains, Ceara. (W. M. Mann.) One male. 
Independencia, Parahyba. (Mann and Heath.) One male,

29 Rehn and Hebard (Proc. Acad. Nat. Sci. Phila., 1916, pp. 291 and 292, 
(1916) ) have made important critical notes on the synonymy of this species. 
9° Journ. N. Y. Entom. Soc., xxiii, pp. 109 to 110, (1915). 
91 There can be little question but that Bruner’s recently described Gryllodes 
macropterus, based on a single male from the State of Bahia, Brazil, andGryl- 
lodes argentinus, described from four specimens from Carcarana, Argentina, 
were founded on macropterous individuals of this very variable and widely 
distributed species. For comments on this genus and species, see Hebard 
(Journ. N. Y. Entom. Soc., xxiii, pj). 101 to 121, (1915) ).
