BRAZILIAN ORTHOPTERA 
venation not sharply defined, the fine neuration lost in the close coriaceous areo- 
lation: marginal field at its widest portion subequal to one-half the entire 
width of the widest portion of the tegmina, with a number of oblique, sub- 
parallel rami of the humeral vein, these generally bifurcate and poorly defined; 
median vein diverging slightly before the middle of the tegmen, bifurcate dis- 
tinctly before the middle of the vein, the rami reaching the suturo-apical 
arcuate portion of the margin; ulnar vein proximad close to tbe discoidal vein, 
slightly but appreciably converging to its point of furcation, thence oblique 
sti’aight to the sutural margin, the median width of this area of convergence 
equal to one-third the greatest distance between the ulnar and anal veins: 
stridulating field relatively elongate, narrow, its free margin broadly arcuate, 
the stridulating vein heavy, depressed, arcuate. Wings normally not pro- 
jecting distad of the closed tegmina. Prosternum unspined: mesosternal 
lobes slightly acute trigonal, the apices relatively sharp: metasternal lobes 
oblique, arcuate with a median truncation of the margin. Disto-dorsal ab- 
dominal segment broadly depressed medio-longitudinally, well arcuate in 
section dorsad of the insertion of the cerci; distal margin projecting and de- 
flexed between the cereal bases in a process which is arcuato-emarginate mesad, 
with short, rounded angulations laterad, from each of which, as well as from 
the middle of the margin, fine sulcations extend to the median depression of 
the segment: suiira-anal plate deflexed, in fact directed ventro-cephalad, 
elongate trigonal: cerci relatively short, moderately incurved with the apex 
bent slightly inwards, tapering, the apex subcompressed and bearing a short, 
dorsal, corneous ridge, which forms the acute apex: subgenital plate moder- 
ately compressed, somewhat elongate, the lateral margins regularly converging 
distad, distal margin relatively narrow, subtruncate; styles very short, conical, 
articulate. Cephalic femora relatively robust, short, not longer than the lateral 
angles of the pronotal disk; ventro-cephalic margin of same with several 
extremely weak serrulations distad, ventro-caudal margin unarmed: cephalic 
tibiae appreciably longer than the femora, quite slender in distal half; tym- 
panum large, open on both faces: median femora faintly longer than the pro- 
notal disk; ventro-cephalic margin with one to two serrulations distad. 
Caudal femora about one-half as long as the tegmina, moderately inflated 
proximad and tapering quite gradually to the moderately slender distal section : 
ventro-external margin with seven to ten spines; ventro-internal margin with 
one to four spines; caudal genicular lobes bispinose. 
General color of head and pronotum honey yellow to yellow ocher, becoming 
mustard yellow on the other thoracic segments and the abdomen, the tegmina 
passing into sulphine yellow and finally (covering a variable portion distad) 
into lettuce green, the limbs yellow ocher to buckthorn brown. It is quite 
proliable that shades of green were the normal color tones and that the pres- 
ent coloration is not that of life, but the specimen shows little discoloration and 
has not been immersed. Eyes russet. Pronotum with the lateral angles of 
fhe disk rather obscurely lined laterad with dull primuline yellow, and mesad 
narrowly with burnt lake, both faintly indicated in the postocular region of 
the head. Tegmina with numerous, very small specklings of liver brown, while
