BRAZILIAN ORTHOPTERA 
Size small: form robust, compact, puliciform: surface of all exposed parts, 
excepting the tegmina, covered to a greater or lesser degree with short, ad- 
pressed hairs. Head short, strongly transverse, its greatest depth subequal 
to the width across eyes: occiput rather strongly declivent ventro-cephalad, 
the least interocular width faintly greater than the greatest width of the eye, 
shallow, paired juxta-ocular depressions situated at the point of least width: 
interantennal portion of rostrum relatively Ijroad, nearly subequal in width to 
the proximal antennal joint, rounded transversely and strongly arcuate when 
seen from the side: infra-antennal portion of face strongly transverse: palpi 
moderately slender and elongate, third and fifth joints subequal in length, 
the former weakly arcuate, the latter strongly tubiform and with its distal 
margin transversely truncate, the distal width of the fifth joint contained about 
two and one-fourth times in the length of the same; fourth joint two-thirds as 
long as the fifth: eyes in basal outline broad subreniform ovoid, their depth 
about twice that of the infra-ocular portion of the genae, when seen from the 
dorsum the eyes are quite prominent and directed moderately cephalad : anten- 
nae more than twice as long as the body, proximal joint large, broad; second 
joint hardly thicker than the succeeding ones, which are covered moderately 
closely with adpressed hairs and with scattered erect hairs. Pronotum with 
its form transverse when seen from the dorsum, the greatest caudal width con- 
tained almost twice in the greatest length, strongly narrowing cephalad, the 
greatest cephalic width equal to about three-fifths of the caudal width: ceph- 
alic and caudal margins of disk subtruncate, the disk very broadly rounding 
ventro-laterad into the lateral lobes: surface of disk with a distinct medio- 
longitudinal impressed sulcus on cephalic half of disk, the median region of 
the disk with, in addition, a poorly defined impressed triangular area: lateral 
lobes subquadrate in form, faintly deeper than long, the ventral angles well 
rounded, the ventral portion of the lobes bent ventro-mesad toward the 
coxae. Tegmina surpassing the apex of the abdomen by nearly the dorsal 
length of the pronotum, relatively broad, the greatest width of the dorsal field 
contained slightly more than twice in the length of the same : dorsal venation as 
shown in figure. Wings aborted. Subgenital plate narrowing distad, the 
apex bisarcuate emarginate: cerci elongate, tapering, surpassing the apices of 
the tegmina, strongly and thickly hirsute. Cephalic and median femora 
moderately robust: cephalic tibiae subequal to the femora, hardly at all fusi- 
form, straight, rather slender; cephalic face imperforate, caudal face with a 
distinct elliptical foramen: proximal joint of cephalic tarsi very robust, nearly 
as deep as the tibiae. Caudal femora in length approximately subequal to 
the tegmina, moderately compressed, in general form rather strongly inflated, 
tapering to a relatively slender apex: caudal tibiae subequal to the femora in 
length, slender, armed with three pairs of marginal spurs, which are very 
elongate, slightly unguiculate distad, diverging from the axis of the tibia 
at an angle of about 35°, external distal spurs very small, the median one 
nearly twice the length of the ventral one, distinctly more than twice the 
length of the dorsal one; internal distal spurs two in number, ventral one very 
long, two-thirds as long as the metatarsus, subfusiform, dorsal one two-thirds 
as long as the ventral one, tapering: caudal metatarsi subequal to the length 
of the remaining joints of the tarsus, relatively heavy, weakly compressed,
