outer corner. Scutellum feebly convex, closely minutely scabrous, lunately 

 impressed, the apical division a little flattened, obsoletely rugulose, with 

 the edge yellowish. Pectoral pieces polished, black, clothed with pros- 

 trate whitish pubescence, the prosternum slenderly margined with white. 

 Legs dull yellow, generally with a black line on the under side of the 

 femora and tibiae; the femora often with piceous dots on the front and 

 back faces; tibiae tipped with piceous, with piceous spines, and sometimes 

 with piceous spots or faint bands at the base of the spines; tarsal joints 

 tipped with piceous and the basal joint entirely piceous, the nails pale 

 piceous. Hemelytra black, almost flat, minutely scabrous, with close, ap- 

 pressed, golden pubescence, and with longer, remote, black hairs exteriorly 

 and basally; the costal margin moderately arcuated, with the edge 

 abruptly, narrowly recurved, and black or rarely piceous; corium with 

 four or five whitsh oblong spots, of which there is a double one on the 

 costal area behind the middle and a similar one near the tip, a large cen- 

 tral one on the discoidal areole and a smaller one farther back; and at 

 the tip of this areole, on the suture, is a larger triangular spot, or very 

 small white spot behind a velvety-black one near the tip of the clavus; 

 membrane dull whitish, dusky at base and tip, with black nervules, and 

 across the middle a series of oblong, blackish spots. Venter black or 

 tinged with piceous (or sometimes pale brownish) ; the apical segment 

 entirely, or only a broad margin, whitish. 



"Length to tip of venter, 3-4 mm.; to tip of membrane, 4-5 mm. Width 

 of base of pronotum, l%-2^4. mm.

 taken at Saint Joseph, Mo., by Mr. E. P. Austin; by myself at Andover, 

 Mass.; and near Baltimore, on the dark sand of a loamy spot near a brook, 

 in May and June; also in Dakota, Nebraska, and Illinois. Some varia- 

 tion occurs in this form, such as the greater expanse of the white spot 

 upon the apex of the corium, and of the pale colors of the prosternum and

"Black, minutely, sparingly pubescent above; general form of S. inter- 

 stitialis Say. Head large, eyes brown, large and very prominent; face 

 minutely, densely punctured, clothed with erect hairs ; cranium wider than 

 in the preceding species, having a small yellow spot each side against the 

 eyes, on a line with the amber-yellow ocelli; lower margin of the clypeus 

 recurved, the tylus and labrum bright yellow, the rostrum, excepting 

 its immediate base, piceous, extending. a little beyond the base of the 

 posterior coxae. Antenna black, the basal joint yellow, black underneath 

 excepting the base and tip; the second joint almost twice as long as the 

 basal, third longer than the basal and shorter than the fourth. The base 

 of head longer than in the preceding species. Pronotum obsoletely 

 punctured, hardly polished, clothed with erect pubescence; the sides ob- 

 lique, slightly curved, the callosities more polished, connate, forming a 

 single transverse elevation, with a rounded pit in the middle; behind it is 

 an "impressed, punctured line. Pectus polished black, obsoletely wrinkled, 

 sparingly pubescent. Legs testaceous; the coxs more or less infuscated; 

 anterior femora black on the middle underneath, the intermediate and 

 posterior pairs with a black spot beneath near the tip, and clothed with 

 thick, whitish pubescence; tip of tibiae and also of tarsi blackish. Hemely- 

 tra dull black, obsoletely rugulose, sparingly clothed with erect pubes- 

 cence, widest just behind the middle; the corium with a yellow dot on the 

 exterior margin near the tip, usually also with three or four more minute 

 ones on the middle suture and one at tip of clavus. Membrane sometimes
