dorsally and laterally infuscated; in the male the dorsal surface of 
all but the last two or three abdominal segments is covered with high 
acute brown tubercles, mostly about three times as high as the basal 
width; on the sides these tubercles grow smaller and shorter, fading 
entirely below; in addition to this conspicuous covering of long 
tubercles the abdomen of the male is ornamented above on each of 
_the 2, 8, 4, and 5 segments by a prominent, smoothly rounded process, 
twice as long as the tubercles, subeylindrical, brownish in color with 
an oblique white V-shaped spot on the anterior surface of each toward 
the base; the process on the 2 segment is smaller and more conical 
than the others. Cerci of both sexes long and stout, but little 
shorter than the pronotum, simple, cylindrical and slenderly pointed 
in the female; in the male cylindrical, apically blunt and with a short 
subapical pointed branch. Legs moderate, dark and light mottled, 
the mottling assuming a somewhat banded form, especially on the 
tibiz; anterior femora about as long as the pronotum, unarmed: 
anterior tibize as long as the femora, unarmed above, except apically, 
below armed with about three sharp spines in the apical half; inter- 
mediate legs similar to the anterior ones except the femora has a 
genicular spine posteriorly and the tibiz are armed above with a 
couple of distinct sharp spines on each side; posterior femora about 
four times as long as wide, moderately swollen basally above, the 
lower margin straight and inconspicuously dentate; posterior tibia 
shghtly longer than their corresponding femora, straight in both 
sexes, armed below on the median line with two or three minute fine 
spines near the apex, and above with a series of triangular teeth and 
five long calecaria on each side, besides apical spurs; tarsi of all the 
legs long, the basal joint equaling in length that of the rest combined. 
Ovipositor stout, of moderate length, apically smooth, the teeth of 
the lower side of the inner valves dull. }
