BRAZILIAN ORTHOPTERA 
Amblytropidia robusta Bruner 
190G. Amhlijlrojndia robjista Bruner, Proc. U. S. Nat. Mus., xxx, p. 631. 
[Sapucay, Paraguay.] 
Tijiica. April 9 to 11, 1913. (Malcolm Burr.) Seven males, 
two females. 
These specimens are slightly different from a topotypic series 
of this species, the caudal femora of the females averaging slightly 
more slender. This feature, however, shows relatively consid- 
erable variation in the Sapucay material, and the difference 
between the Tijuca females and the average of the topotypes of 
that sex (seven in number) is no greater than the individual varia- 
tions in this feature among the latter series. One of the females 
has a pale subcostal tegminal line, which is lacking in all the other 
individuals of robusta seen by us. As we know this variation 
occurs in A. vittata the feature is only individual. 
The range of the species is considerably extended to the east- 
ward by the present record, the previously known localities for 
the species being Sapucay and Puerto Bertoni, Paraguay and the 
Misiones, Argentina. 
Peruvia ensicornis (Rehn) 
1913. Fenestra ensicorne Rehn, Proc. Acad. Nat. Sci. Phila., 1913, p. 83, figs. 
1 and 2. April 30, 1913. [Espirito Santo, Brazil.] 
1913. Toxoplerus orientalis Bruner, Ann. Carneg. hlus., viii, p. 449. May 5, 
1913. [Rio de Janeiro, Brazil.] 
Tijuca. April 9 to 11, 1913. (Malcolm Burr.) One male, 
one female. 
For the use of Peruvia Scudder in place of Toxopterus Bolivar, 
see the recent discussion of the problem by the author.'^ The 
above synonymy is evident after a careful study of the type of 
ensicorne and the description of orientalis. The type of ensicorne 
has now lost its antennae, and these were evidently incomplete 
when the species was described and figured, thus the clavate apex 
was not described. 
It is evident from an examination of this species and comparison 
with the genotypes of Peruvia {P. nigromarginata) and Fenestra 
{F. hohlsii), that the two genera are quite close to one another, 
the present form constituting, in fact, a connecting link, although
