 B. A dark streak on embolium, scutellum dark.

"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, greateft 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 2^/^ times as broad as long alcng the median line; 

 broader at base than at distal margin; both basal and distal margins 

 more or less sinuate ; edges curved regulai'ly from the eyes to the humeral 

 angles, which are rounded; disc with indented lines behind the head, 

 parallel to the anterior margin, the first line as long as the distance be- 

 tween the e; es, 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 broadened 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 

 vdth 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 tibiae, which are curved and furnished with a one-iointed 

 tarsus, destitute of claws. Second and third pair cursorial, with normal 

 femora and tibiae, with two-jointed tarsi, armed with moderately long, 

 .slender claws. The tibiae 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 

 caudad 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 segTnents 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.;
