the greatest length; cephalic margin of the same slightly sinuate, angles and 
remaining margins of the loljes as in hranneri. Tegmina falling very slightly 
short of the tips of the caudal femora, failing to reach the apices of the wings 
by slightly more than the dorsal length of the pronotum, in form moderately 
lanceolate, broader than in hranneri, apex narrowly rounded, sutural in posi- 
tion, the form faintly tapering from the proximal third: mediastine vein 
incomplete; discoidal vein with three regular rami to the sutural margin, these 
with the usual connecting sectors: stridulating field proportionately shorter 
and broader than in hranneri; for venation see figure. Wings with the distal 
portion subcoriaceous like the tegmina, apex injured in type, presumably 
acuminate. Abdominal segments weakly carinate dorsad, the penultimate 
dorsal abdominal slightly produced mesad into an obtuse-angulate, dorsad 
compressed projection, which bears a number of setae, lateral margins of this 
projection very faintly arcuate-emarginate : disto-dorsal abdominal segment 
strongly transverse, narrow, mesad broadly obtuse-angulate emarginate: 
supra-anal plate subtrigonal, distal margin obtuse-angulate and thickened and 
hirsute as in hranneri; cerci of a character which much suggests those of 
hrasiliensis and peruviana vuth the slender distal portion missing, the shaft is 
tapering to about the distal two-thirds, straight when seen from the dorsum, 
slightly ascending distad when seen from the side, distal third bent inward and 
subdepressed, expanding into a structure of the tj'pe placed mesad in hras- 
iliensis and allied species, the distal prong narrowing and with a blunt tooth, 
the proximal section broader and excavate with a short, recurved, apical tooth, 
the free (internal) margin of this process sigmoid in outline, the portion prox- 
imad thickened: subgenital plate as in H. hranneri. Limbs less elongate than 
in H. hranneri; femora unarmed beneath, cephalic and median genicular 
lobes bispinose, caudal genicular lobes unispinose; caudal femora very slightly 
shorter than the tegmina. 
General color pyrite yellow passing into pale old gold on the head and pro- 
notum and to courge green distad on the tegmina and wings. Antennae 
distad of and including the second joint washed with pale morocco red, weak- 
ening distad; eyes brussels brown. Pronotum with the lateral angles of the 
disk lined with pale morocco red. Tegmina with the region of the anal vein 
broadly washed with dull claret brown. Femora more or less suffused with 
pale morocco red. Abdomen largely dull aniline yellow. 
Length of body, 16 mm.; length of pronotum, 3.6; greatest (caudal) width 
of the pronotal disk, 2.9; length of tegmen, 22.8; greatest width (at proximal 
third) of tegmen, 4.2 ; length of caudal femur, 21. 
The type of this interesting species is unique.
