BRAZILIAN ORTHOPTERA 
margin strongly arcuate: e}-es weakl}^ projecting cephalad, appreciably com- 
pressed laterad, in basal outline subreniform, broader dorsad than ventradr 
antennae at least twice as long as the body, relatively heavy, moniliform, the 
joints longest mesad; proximal joint depressed, its dorsal surface impressed. 
Pronotum moderately transverse, its median length contained about one and 
one-half times in the greatest caudal width of the same, dorsal surface strongly 
arcuate in transverse section, broadly rounding into the lateral lobes: cephalic 
margin of disk concavo-truncate, caudal margin bisimiate laterad, very broadly 
obtuse-angulate mesad; lateral borders of disk regularly, though not strongly, 
diverging caudad; iiaired impressions of the disk ovoid in shape: lateral 
lobes decidedly longitudinal, slightly deeper caudad than cephalad, the caudal 
depth contained about one and two-thii'ds times in the greatest length of the 
lobes; ventral margin of the lobes arcuate, the ventro-cephalic and caudal 
angles broadly rounded. Tegmina reaching to the apices of the caudal femora 
and surpassing the aj)ex of the abdomen by the length of the head and pronotum 
combined, very elongate, the greatest width of the dorsal field contained nearly 
five and one-half times in the length of the same: lateral field subequal in 
depth in proximal third, regularly narrowing thence; mediastine vein trira- 
mose; lateral field with three free veins proximad; humeral and discoidal 
veins simple: dorsal field with sharply defined, elevated and regularly spaced, 
relatively simple, longitudinal venation, the cross-veins w'eak, rather irregular 
and often sigmoid: median vein straight, with three rami, which are as lon- 
gitudinal as the median vein itself, the distal more distinct in its origin than the 
median and proximal ones; anal and three axillary veins distinct and regular. 
Exposed portion of the closed wings slightly longer than the length of the head 
and pronotum combined. Cerci short, not surpassing the apices of the teg- 
mina when extended, sharply tapering proximad, very graclually so and very 
slender distad, falcate, strongly decurved: subgenital plate as in cearensis but 
the distal margin weakly arcuate. Limbs slender, the cephalic and median 
femora deeper than usual in limbs in general so slim: third tarsal joint slender 
in all tarsi. Cephalic tibiae with cephalic face having an elongate elliptical 
foramen, imperforate on caudal face. Caudal femora with the greatest depth 
contained about four and one-half times in the greatest length : caudal tibiae 
very slender; dorsal margins armed distad with five major spines, which are 
very slender, the intercalated spinulations on the external margin numbering 
(reading distad) 6, 5, 2, 2 or 4, 4, 3, 2 — on the internal margin, 3, 3, 2, 1 or 
3, 3, 3, 1 ; distal external spurs small, the dorsal little more than half as long as 
the median, and the ventral but little smaller than the median; distal internal 
spurs elongate, the ventral about two-fifths as long as the dorsal, which latter 
is but little shorter than the metatarsus: caudal metatarsi with dorso-external 
margin with two spinulations, dorso-internal margin with a single (distal) 
spinulation; internal metatarsal spur about as long as the metatarsus, ex- 
ternal one somewhat shorter.

Size larger. Head slightly shorter and broader: eyes less projecting cephalad:
