whitish, with a large black spot at the base inwardly, a small subquadrate 

 one against the base exteriorly, and behind this an orange spot which is 

 bounded behind by another black spot; the nervures blackish. Others 

 have the membrane black, with a yellow spot against the exterior margin 

 and a few pale vestiges on the middle. Venter, black, more or less tinged 

 with piceous, polished, very remotely pubescent, minutely inconspicuously 

 punctured, tip of the genital segment broadly white. Length, 4-4 1/^ mm. 

 Humeral breadth, 1 V2 mm. Extreme width of hemelytra, 2 mm." — Uhler.

"Closely resembles .S. marginaUs Fallen. Deep, dull black, sparsely 

 clothed with golden prostrate pubescence, and the head and pronotum 

 with a few erect black hairs. Head above broad and blunt, the base form- 

 ing a short neck; the surface minutely scabrous; eyes prominent, brown- 

 ish, moderately oblique; front moderately narrow and flat, not distinctly 

 arched at base; the lower margin of the clypeus callous, feebly recurved, 

 testaceous, black in the center; tylus and labrum forming an arched 

 bridge, dull ochei'ous, the former a little concave on the sides inferiorly, 

 the latter piceous at tip and a little pubescent. Rostrum reaching upon 

 the intermediate coxEe, dark piceous, paler at tip. Antennse moderately 

 stout, clothed with pale, stiff hairs; basal joint dull yellow, black beneath; 

 second piceous, paler at base and tip, not twice as long as the basal one, 

 and a little thickened at tip ; third and fourth dull blackish, subfusiform, 

 subequal, each longer than the basal one. Pronotum transverse, sub- 

 trapezoidal, rather flat, with the sides very oblique, hardly curving; the 

 submargin broadly depressed and gradually narrowing toward the front; 

 the callosities feebly elevated, deeply and broadly foveate in the center, 

 bounded by a deeply impressed line; the surface minutely and densely 

 rugulose ; posterior m^argin very slightly concave, with the humeral angles 

 moderately produced, very broad, and with a large, low fold near the 

 outer angle. Scutellum scabrous at base, minutely, transversely wrinkled 

 on the apical half; the central impression lunate, distinct. Legs dull 

 testaceous, very hairy, more or less marked with piceous on the femora, 

 particularly beneath, on the tibiae, somewhat in spots, the tips, spines, and 

 the basal and apical joints of the tarsi piceous-black, the nails dull tes- 

 taceous. Sternum and under side of the body shining black, minutely, 

 closely whitish pubescent; the extreme edge of the prosternum and of the 

 ventral segments and a broad end of the genital segment of the female 

 whitish. Hemelytra deep black; the corium closely yellow and black 

 pubescent, densely shagreened, the costal margin moderately arcuated, 

 broadly and continuously flattened, recurved from the base to behind the 

 middle; the costal area with a testaceous small spot behind the middle 

 and two smaller parallel ones near the tip, the middle nervure with a spot 

 near the base, and the middle areole with a larger spot at tip and two or 

 three smaller ones near the tip; the clavus with a small yellow spot near 

 the tip; membrane dull white, fuscous at base and with a broad cloud at 

 tip, a transverse series of oblong fuscous spots across the middle and a 

 spot at the tip of the exterior areole; the nervures piceous or black. 



"Length to tip of hemelytra, 4-4% mm.; to tip of venter, 3y2-4 mm. 

 Width of base of pronotum, 1 1/2 mm. 



"A few specimens from the Museum of Comparative Zoology, collected 

 in Cambridge, Mass. 



"This is a robust little species, very closely related to S. inter stitialin 

 Say, and perhaps only a variety of it. But the different shape of the 

 pronotum, with the other details, will at present serve to separate it." — 

 Uhler. 



Distribution: Quebec, New Hampshire and Massachusetts.
