Hemelytra black, almost flat, minutely scabrous, with close, appressed, 

 goldeu 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 whitish 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 central 

 one on the discoidal areole and a smaller one farther back ; aud 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 ; mem- 

 brane 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 millimeters; to tip of membrane 4-5

Inhabits Missouri, Mr. Say. Specimens in my own collection were 

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

 ver, 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 variation occurs in this form, such as the greater expanse of the 

 white spot upon the apex of the corium, and of the i)ale colors of the 

 prosternum and legs. 



The references to other localities in my List of Hemiptera, published in 

 Dr. Hayden's Bulletin, p. 67, must be expunged, as they refer to other 

 forms, which, for the present at least, we are impelled to consider 

 species.
