■castaneous, pale at base ; summit of head testaceous, flecked, especially in the mid- 
dle, with black ; a broad piceous stripe extends from the eye to the posterior border 
of the upper half of the deflected lobes of the pronotum. Lower portion of these 
lobes of the color of the genae ; disk of pronotum testaceous, flecked with black dots, 
and a pair of small black spots lying on either side of the middle line on the posterior di- 
vision of the anterior lobe ; anterior lobe distantly, coarsely, and shallowly punctate; 
posterior lobe profusely and less coarsely punctate; transverse sulci of anterior lobe very 
distinct; median carina sharp and distinct on posterior, obsolescent on anterior lobe; 
posterior margin of pronotum nearly straight, scarcely angulate. Tegmina shorter 
than the pronotum, broadly rounded, not at all produced at tip, testaceous, with dark 
veins, the inner area paler. Hind femora compressed, outer surface blackish, under 
surface pale sanguineous ; hind tibiae very dark bronze-green ; hind tarsi castaneous, 
infuscated in spots. Abdomen yellowish, the sides with a narrow, tapering, longi- 
tudinal piceous band. Anal cerci strongly compressed, very broad and rounded on 
basal half, with marginal borders, and a little tumid in the middle, the apical half 
subcylindrical, slender, tapering, pointed, not one-third the width of the base, the 
whole not more thau half as long again as broad. 
Length of body 17 m,n , of antennae 6 mm , of tegmina 3.75 mm , of hind femora 10 mm .

Front of head brownish testaceous, faintly flecked with fuscous, excepting in a clear 
livid stripe in front of the lateral carinae, passing from between the antennae and the 
•eyes to the outer base of the mandibles ; genae bluish livid below, becoming infuscated 
above, and deepening to black behind the eyes; summit fusco-testaceous, with an ar- 
cuate dusky or blackish line from the front edge of the eyes to the posterior border, 
where the upper limit of the black stripe behiud the eyes is edged above with a 
lighter more or less yellowish color. Antennae about as long as the hind femora in the 
male, fusco-testaceous or castaneous, subdepressed, equal throughout in both sexes. 
ISyes separated above by as much as the outer bases of the antennae, the front of the 
fastigium bent at a right angle, slightly margined,' the lateral foveolae straight, equal, 
meeting in front, sulcate, many times longer than broad; frontal costa perfectly flat, 
expanding and fading below the ocellus. Pronotum brownish, the lateral carinae 
generally marked distinctly with a dull yellow stripe, the lateral lobes mostly black 
or blackish above, usually deepest on the middle of the front lobe, its anterior margin 
often marked with yellow and with a central, very short, longitudinal, pale-yellow 
dash ; median and lateral carinae equally distinct and rather slight : the front and 
hind margin slightly angled. Tegmina ovate-sublanceolate in the female, shorter than 
the head and thorax together, oblong-obovate in the male, much longer than the head 
and thorax together, rounded apically ; in both obscure dark fuscous, with blackish 
flecks. Hind femora black on the outer face, but the lower carina and inferior face 
pale yellow, the superior face brown, with two oblique dark transverse stripes, which 
also cross the yellow interior face ; apex black. Hind tibiae black at base, followed 
by a broad pale yellow and then a fuscous belt, the apical half sanguineous, the 
spines black tipped. Abdomen brownish fuscous above, yellow below, the.^wo inter- 
•digitating on the sides.
