BRAZILIAN ORTHOPTERA 
weakly strumose ventrad: ovipositor faintly more than one and one-half 
times as long as the disk of the i^ronotum, moderately arcuate in proximal half, 
thence distad nearly straight, faintly tapering; dorsal margin bent arcuate at 
the proximal third, thence straight to the rotundato-truncate apex, ventral 
margin moderately arcuate; distal half of dorsal margin, apex and extremity 
of ventral margin serrulate: subgenital plate trigonal, with the apex rotundato- 
truncate. Cephalic and median femora unarmed ventrad; cephalic tibiae 
with two to three spines on the dorso-caudal margin. Caudal femora three- 
fourths as long as the tegmina, relatively slender, genicular lobes briefly bispi- 
nose, ventro-external margin with three spines, ventro-internal margin with 
six to seven spines. 
Coloration almost completely destroyed by immersion in liquid preserva- 
tive. The discoidal field of the tegmina shows two, and traces of a third, 
longitudinal series of darker spots. The foramina on the cephalic tibiae and 
all of the infra-cercal plates except their small strumose section, black. 
Length of body (exclusive of ovipositor), 24 mm.; length of pronotum, 5.7; 
greatest dorsal (caudal) width of pronotum, 4.6; length of tegmen, 36.5; 
greatest width of tegmen, 9.2; length of caudal femur, 27.2; length of ovi- 
positor, 9.5. 
The tj^pe is unique.

Para, Para. (C. F. Baker.) One female. 
This specimen full agrees with the original description, based 
on the male sex, in the characters found in both sexes. The 
characters of the female genitalic features are summarized to 
help in the recognition of that sex of the species. Anal segment 
(disto-dorsal abdominal segment) as in the male; supra-anal 
plate small, acute trigonal; cerci stout at base, regularly tapering, 
arcuate incurved, apex acute: ovipositor in length half again as 
long as the pronotal disk; moderately bent arcuate at the proximal 
third of the dorsal margin, this straight distad, ventral margin 
regularly arcuate; depth of ovipositor subequal, apex rotundato- 
subtruncate, crenulato-denticulate on distal third of dorsal 
margin, at apex and briefly on the ventral margin: subgenital 
plate V-shaped in section, short, distal margin bisinuate emargi- 
nate: infra-cercal plates produced ventro-distad in an acute, 
digitiform, compressed lobe, which moderately embraces the 
ovipositor base. This specimen measures as follows: length of 
body (exclusive of ovipositor), 23.2 mm.; length of pronotum, 
6.7; greatest (caudal) width of pronotal disk, 4.5; length of
