genae more inflated than in the male. Tegmina with dorsal field having eight 
almost longitudinal sectors, the four ilistal being rami of the median vein, the 
next is the ulnar vein, the anal following and finally two axillaiy veins: the 
sectors derived from the median vein are connected by infrequent cross-veins, 
which are placed at right angles to the rami themselves, between the other 
sectors the cross-veins are nearly longitudinal, somewhat irregular in position 
and distinctly sigmoid in shape, excepting distad, where the cross-veins take the 
position and disposition they assume between the sectors derived from the 
median vein, a tendency toward false intercalated longitudinal nervures is 
seen proximad. Cerci slightly surpassing the tips of the tegmina. Ovipositor 
but slightly shorter than the caudal femora, compressed; apex acuminate, the 
extreme tip very acute, ventro-laterad armed with strong, rather irregular, 
recurv'ed teeth, the dorsal surface of the apex slightly flattened, the external 
surfaces moderately rounded and strongly shagreenous. Caudal tibiae with 
intercalated spinulation formula on the external margin, 7, 6, 3.2 — on the inter- 
nal margin, 4, 4, 3, 0. 
Coloration tones completely destroyed by immersion in a liquid preserva- 
tive. The only evident features are: a regularly placed pattern of ver}- small 
fuscous punctulations on the pronotum, cephalic and median limbs, distal 
extremity of the caudal femora and (sparsely) greater portion of the caudal 
tibiae; a relatively narrow fuscous postocular bar on the head and pronotum, 
which is narrow and not sharply defined; a medio-longitudinal bar of fuscous 
on the head and pronotum, this being divided by a thread of the general color; 
lining with fuscous of the proximal third of the humeral vein of the tegmina; 
median vein of the wing sparsely and strongly, and the longitudinal veins of 
the exposed portion of the folded wings, more closely and less distincth', ticked 
with fuscous; eyes obliquely trilineate with fuscous, the lines somewhat 
sigmoid; antennae very sparsely annulate with fuscous; ventral surface of the 
caudal tibiae washed with weak fuscous; ovipositor narrowly lined with fus- 
cous laterad, the apex ventrad washed with the same. 
(J'itype). Length of body, 10.6 m.; length of pronotum, 1.9; greatest 
(caudal) width of pronotum, 2.8; length of tegmen, 11.8; greatest width of 
dorsal field of tegmen, 2.2; length of caudal femur, 9.2. 
9 (allotype). Length of body, 12.2 mm.; length 6f pronotum, 2.2; greatest 
(caudal) width of pronotum, 3.3; length of tegmen, 13.3; greatest width of 
dorsal field of tegmen, 2.5; length of caudal femur, 11.1; length of ovipositor, 
8.8. 
The type and allotype are the only specimens of this easily 
recognized species seen by us. The variation in the formulas of 
the intercalated spinulations of the dorsal margins of the caudal 
tibiae show how unimportant these features are, and how little 
dependence can be placed upon them as diagnostic characters.
