diagonal vein prominent; postaxillary veins three in number, two moderately 
sigmoid, one arcuate; speculum with its length (oblique) slightly greater than 
the width, the proximal outline rounded obtuse-angulate, costal outline sim- 
ilar, section toward the sutural margin arcuate, distal arcuation with a rounded 
disto-costal rectangulation, the speculum with a single cross-vein; distal area 
with three rami of the median vein. Wings i)rojecting distad of the closed 
tegmina a distance equal to one and one-half times the length of the pronotum. 
Cerci falling slightly short of the tips of the closed wings: subgenital plate 
subcompressed distad, caudal aspect of the same with the margin U-shaped 
mesad. Limbs rather robust. Cephalic tibiae fusiform, considerablj" in- 
flated mesad, more slender distad than proximad: cephalic face of the cephalic 
tibiae with a narrow, linear foraminal opening, the caudal face with a semi- 
ovate tympanum, the straight portion of the outline of which is flexor in posi- 
tion: cephalic tarsi very short. Caudal femora not two-thirds as long as the 
tegmina, rather regularly tapering, the distal extremity relatively slender: 
caudal tibiae armed distad on both margins with four major spines: caudal 
metatarsi short, the dorsal length but little more than the length of the dorso- 
internal distal spur of the tibiae, the dorsal margins of the metatarsi armed 
wuth one (internal) or tw’o (external) spines.

The following features are those of difference from the description of the 
male (type). Lateral ocelli slightly smaller than, but of similar form and in 
similar position to, those of the male sex, separated from the eyes by about the 
greatest ocellar length. Pronotum slightly more longitudinal than in the 
male. Tegmina with the greatest width of the dorsal field contained about 
four and one-half times in the tegminal length; lateral margins of closed 
dorsal fields parallel in proximal half: mediastine vein with eight oblique 
rami, six free veins present proximad in the marginal field; humeral vein fol- 
lowing the regular curve of the mediastine vein, being connected with the same 
by means of a number of short cross-veins, which form small, rectangulate 
areolets; discoidal and median veins simple, faintly sinuate proximad, the 
median with four oblique distal rami, which form an integral part of the regular 
dorsal reticulation; ulnar vein triramose, the rami regularly oblique and 
paralleling the anal and axillary veins and the distal rami of the median vein; 
the anal vein simple, the axillaries two in number, the whole dorsal venation 
with quite regularly placed cross-veins, which make rectangulate areolets, these 
becoming irregular proximad between the ulnar and anal veins. 
General color of the dorsal surface of the head and pronotum, burnt sienna; 
of the dorsal field of the tegmina and the visible portion of the closed wings, 
ochraceous-buff; lateral lobes of the pronotum, genae and palpi, blackish 
brown; almost all of the cephalic limbs, greater portion of the median limbs, 
the distal half of the caudal femora and caudal tibiae and tarsi, fuscous. Ven- 
tral surface of thorax and coxae light ochraceous-buff, abdomen ventrad pale
