middle, curving round the hind margin nearly to the anal-angle, and 
extending up the sub-frontal space to the base; apex transparent; 
veins dusky. Posterior femora crossed externally and internally by 
three black bands; posterior tibiae reddish-yellow, with a broad, pale 
ring near the base. 
Dimensions. — f. Length, 1.4 to 1.7 inches; elytra, 1.28 inches; pos- 
teaior femora, 0.90 inch; posterior tibiae, 0.82 inch, m.— Length, 1 to 
1.25 inches.

Female .—Of large size. Vertex broad, the slightly elevated margins 
suddenly curved outward opposite the eyes; a slight median line, with 
minute tubercles at the tip. Face slightly curved under; frontal costa 
prominent, broad, somewhat expanding below, and obtusely sulcate; 
lateral carinae distinct, curving outward to the corners of the face. 
Pronotum covered somewhat regularly with small tubercles, otherwise 
not very rugose, being but slightly wrinkled transversely; median Ca¬ 
rina moderately elevated, nearly straight on‘top, interrupted only by 
one slight notch; lateral carinae wanting on the anterior lobes, dis¬ 
tinct, but obtuse on the posterior lobe. Elytra and wings longer than 
the abdomen; there is in the female a distinct expansion of the lower 
border of the elytra near the base, the nerves of the 'dorsal held ra¬ 
mose and prominent. Posterior femora very broad, the width near 
the base being about equal to the width of the elytra; the upper and 
lower carinae much elevated and sharp; not reaching the tip of the 
abdomen. Valves of the ovipositor very robust, elongate. 
Color. —Pale-reddish or yellowish-brown, with dark-brown or fus¬ 
cous spots. Head and thorax (in dried specimens) dark reddish-brown, 
the sides of the pronotum nearly black; it is probable that this in 
in living specimens, is paler and tinged with olive-green. Elytra roseate 
and somewhat opaque at the base, transparent at the apex, marked 
with tolerably large dark-brown spots, somewhat elongate transversely, 
placed irregularly; one of the largest crosses the lower field at the 
expansion near the base. Wings with the disk and basal portion a 
bright, deep orange-red, semi-opaque; exterior to this and just beyond 
the middle they are crossed by a rather a narrow fuscous band, which 
curves round on the posterior margin to the anal angle; it also curves 
slightly inward in front; exteriorly it fades into the black-nerved, 
transparent, apical portion; the anterior margin is bordered with a red 
stripe, which extends to the base; this is separated from the red of 
the disk by a black ray, which also extends nearly to the base. Ab¬ 
domen glabrous, much more so than the rest of the body. Legs gla¬ 
brous, of a clear reddish-brown; the posterior femora internally deep
