broad again as the first antennal joint, a little broader in the ? than 
in the 3; foveola rather shallowly sulcate, subspatulate in form, the 
bounding walls thick and low; frontal ridge very equal, flat above, 
gently sulcate at and below the ocellus. Pronotum simple, the pos- 
terior lobe slightly expanding, punctulate, the median carina slight 
but distinct upon it, but wholly wanting in front; lateral carinz obso- 
lete ; transverse sulci of anterior lobe distinct, subcontinuous across 
the middle. Tegmina very slender, extending beyond (¢) or fully 
to (2) the tip of the abdomen. .Terminal ventral segment of ¢ ab- 
domen elongated scoop-shaped, the extremity a little produced, en- 
tire; supraanal plate subquadrate, longer than broad, the sides sub- 
parallel on basal half, beyond tapering rapidly, the tip triangularly 
produced, sharply angulated; marginal apophyses of preceding seg- 
ment stout, depressed, attingent at base, beyond with inner margins 
separated at an angle of 45°, the outer margins straight and parallel, 
the extremity obliquely docked and scarcely incurved, each more 
than half the length of the supraanal plate and nearly three times as 
long as basal breadth; anal cerci formed on either side of a long, 
slender, straight, compressed finger much expanded above at the 
extreme base, scarcely tapering, bluntly and roundly terminated, 
directed backward, somewhat upward, and a little inward, and 
about as long as the first hind tarsal joint; basal tooth of lower

mottlings of dusky ferruginous; antennz dull pale castaneous; behind 
the eye a broad piceous belt, sometimes broken, sometimes entire, 
crosses the anterior lobe of the prothorax on the upper half of the de- 
flected side ; the upper surface*of the prothorax is brownish yellow, 
heavily punctate or mottled with fuscous. Tegmina with an ob- 
scure median row of alternate dusky and pallid spots; hind femora 
brownish-yellow, more or less tinged with plumbeous, the interstices 
dusky, with faint indications of dusky transverse stripes above; 
hind tibiz bluish-green, sometimes dotted with black and with black
