“Head: Broader, including eyes, than long; front more or less re- 
motely punctuated and furrowed; width at base and at widest part sub- 
equal; eyes longer than wide, greatest width about one-third from the 
distal end; sinuate in the inner margin, converging toward the distal 
end more than toward the proximal end. Labrum broader at base than 
long; triangular in shape, with rounded apex attaining the middle of the 
third segment of the rostrum. Rostrum short, stout. 
“Pronotum about 21%4 times as broad as long aleng the median line; 
broader at base than at distal margin; both basal and distal margins 
more or less sinuate; edges curved regularly from the eyes to the humeral 
angles, which are reunded; disc with indented lines behind the head, 
parallel to the anterior margin, the first line as long as the distance be- 
tween the eves, and diminishing in length posteriorly, giving an obtusely 
triangular shape to the lined area, the remainder of the disk coarsely 
punctuated, caudad of the pronotal suture it is shagreened in wavy lines. 
“Scutellum about twice as’ long along the medial line; apex blunt; 
sides sinuate, shagreened. 
“Hemelytra narrower than abdomen, but extending to end of same. 
Membrane distinct, but merging insensibly into the corium. Embolium 
flattened and breadened marginally, extending beyond the abdomen. The 
three last connexival segments have prominent posterior angles. Entire 
hemelytra, including the membrane, covered with very short, sparse 
golden hairs. Mesosternal keel slightly raised, grooved longitudinally 
with hairs arising on either side, and nearly covering the groove. 
“Abdomen: Genital segments prominent in male, flattened and cleft 
in female. These segments are somewhat complicated, and no adequate 
description can be made without a dissection. 
“Pedes: First pair raptorial, with incrassate femora grooved for the 
reception of the tibiz, which are curved and furnished with a one-iointed 
tarsus, destitute of claws. Second and third pair cursorial, with normal 
femora and tibiz, with two-jointed tarsi, armed with moderately long, 
slender claws. The tibiz are furnished with moderately long spines in 
two rows. 
“Coloration: Head flavous, with a dark median line of varying width, 
sometimes reduced to a triangle at the vertex, and at others entirely 
absent or very faint. Prothorax also flavous, the punctuations of the 
disk brown, the flattened outer margin much lighter in color; the area 
eaudad of the suture, more or less variegated with perpendicular black 
lines of varying widths. Scutellum brown, the apex sometimes lighter in 
color, approaching to flavous; some individuals have lighter vermicula- 
tions in the disk. Hemelytra also brown, with lighter vermiculations, 
the ground color of var ing shades; the darker forms have two flavous 
spots on the corium at the edge next to the membrane, which disappear 
in the lighter forms. The embolium is testaceous, darkening caudad. 
The connexival segments are black posteriorly. The abdomen varies 
from testaceous to dark brown. The legs are concolorous except the 
spines, which are darker and black-tipped; the anterior legs are flavous, 
except the apex of the tarsus, which is dark. Labrum flavous; terminal 
segment of rostrum darker at the lip. 
“Measurements: Head—long., 1.5 to 1.7 mm.; lat., 2.6 to 2.9 mm.; 
long., 1.8 to 1.9 mm.; lat., 2.8 to 3 mm. Pronotum—long., 1.7 to 2 mm.;
