BRAZILIAN ORTHOPTERA 
bifurcate ramus of the anal vein ; axillan.* vein simple, obtuse-angulate before 
reachine the anAl node : diagonal vein arcuate proximad. thence nearly straight 
longitudinal to the cephalic angle of the speculum; post -axillan.- veins three 
in number, the costal two strongly arcuate, the third ven.- faintly arcuate: 
speculum with its greatest length (oblique) exceeding the greatest width, 
obtuse-angulate proximad. single trans\-erse vein arcuate costad: distal area 
with four arcuate rami, the proximal strongly, the distal weakly so, three 
generally- longitudinal nemires springing from the margin of the speculuin 
toward the sutural margin, the entire area reticulate with irregularly placed 
cross-veins. Wings surpassing the apex of the tegmina by about half the pro- 
notal length. Cerci reaching .almost to the tips of the wings : subgenital plate 
with a small and weak mesal creasing of the distal margin. Limbs relatively 
short and moderately robust: third joint of all tarsi relatively long and ex- 
tremely slender. Cephalic tibiae not enlarged, veiy faintly tapering in distal 
hah': foramen on cephahc face elliptical, on caudal face similar but faintly 
larger. Caudal femora robust, the greatest width more than a third of the 
length, distal extremity relatively slender: caudal tibiae with five external and 
four internal major spines on the distal half, the spinulations of both margins 
numbering reading distad.' 2. 2. 1. 0, the last space lacking on the internal 
margin : external distal spurs with the median nearly twice as long as the dor- 
sal. internal distal spurs with the ventral one half as long as the dorsal one: 
caudal metatarsi no longer than their internal distal spur; armed on the dorso- 
extemal margin with two spinulations, the distal one large, the other small, on 
the dorso-intemal margin with a single large distal one. 
Allotype. — 5 : .Same data as type. [Acad. Xat. Sci. Phila.] 
This sex differs from the above description of the male tj-pe) in the following 
noteworthy features. Lateral ocelli relatively smaller. Pronotum more 
decidedly transverse, its greatest length contained one and one-half times in the 
greatest caudal width of the disk. Tegmina distinctly surpassing the apices of 
the caudal femora, reaching almost to the tips of the cerci and o^'ipositor, when 
seen from the dorsum the lateral outlines of the dorsal fields are arcuate distad 
to the apex: marginal field narrowing regularly in the distal half; mediastine 
vein with eleven to twelve rami, all obUque and but little sigmoid; humeral and 
discoidal veins simple, parallel, following the curve of the mediastine vein; 
median vein with its obhque rami distad) so fused into the general reticulation 
of the dorsal field that their origin distinct from the other regular obhque 
sectors of the field is not readily noticed, the sectors moderateh* direct but 
somewhat sinuate, eleven in number including those of median origin, all con- 
nected by irregular, rather closely placed, cross-veins, which form areolets of 
irregular shapes but of clear definition. Caudal tibiae with external margin 
having a secondary- spinulation formula of .3, 3, 1, 0, on internal margin, 3, 3, 2. 
CHipositor about four-fifths as long as the caudal femora, deplanate; the apex 
hardly expanded, rather broadly rounded; dorsal valves distad with numer- 
ous trans^•erse. closely placed, sinuate, file-hke carinations, the arcuate margin 
of the same area crenulato-denticulate; ventral valves laterad with two obtuse- 
angulations, the distal margin arcuate, entire.
