BRAZILIAN ORTHOPTERA 
This specimen fully agrees with Stal’s description of this ap- 
parently little known species. While the median carina of the 
pronotum is somewhat more evident than Stal’s term “obsoleta” 
would indicate, it is not as solid or sharp as in the allied S. robushis 
Bruner, which is a larger species with a broader interocular space, 
a silicate frontal costa and shorter tegmina. This appears to be 
the first exact record of the species. 
Schistocerca fimbriata (Thunberg) 
1824. [Gryllus] fimbriatus Thunberg, M6m. Acad. Imp. Sci. St. Petersb., ix, p. 
428. [Brazil.] 
Schistocerca flavo-fasciala St&l, Scudder, etc., (not Acrydium flavo-fasciatum] 
DeGeer). 
Tijuca. April 9 to 11, 1913. (Malcolm Burr.) Two females. 
Petropolis. April 12 to 14, 1913. (Malcolm Burr.) Four 
males, one female. 
As we have already shown® DeGeer’s flavo-fasciatum is distinct 
from this species, being a form of northern South America. St^l, 
who examined the type of Thunberg’s Gryllus nitens, fimbriatus 
and mtidus, considered these species to be the same as DeGeer’s 
form, the type of which was missing. Of these names nitens, 
the oldest, seems from the description more likely to be true 
flavo-fasciata. Stal was, of course, unaware of the differences 
separating the true flavo-fasciata (aequalis Scudder) and the species 
called flavo-fasciata by Scudder. Thunberg’s fimbriatus stands 
next in availability and may be used, at least provisionally, for 
the present species, as it shows no features of disagreement from 
the original description. 
This species can be readily distinguished in both sexes from 
flavo-fasciata by the narrower marginal field of the tegmina, 
which as far as available material goes is always rather narrowly 
striped with pale, while the male cerci are more tapering and 
never broadly truncate distad as in the other species. 
Scudder’s infumata is quite close to fimbriata, as type material 
of the former now before us shows, and it is very probable that 
infumata will eventually prove to be but a geographic race or an 
extreme refinement of the characters of fimbriata. 
The species is known to range from Asuncion and Luque, 
Paraguay, north to Chapada and Para, Brazil, east to the vicinity
