margin, and the tip with a transverse black spot; nervures black; middle 
areole with an oval spot near the outer nervure, basally, a round one a 
little way behind this, a few specks behind the middle, a dot near the

membrane pale yellow, a little clouded at base and on the apical. margin,

“Length to tip of hemelytra, 3-3% mm. Width of base of pronotum, 
1% mm. 
“Common in Maryland, within the limits of the metamorphic belt, upon 
damp sand formed by the disintegration of the rocks, near creeks and 
brooks, in June and July. It is also common in Northwestern and North- 
ern Florida; and specimens have been sent to me from Texas, Illinois, and 
Pennsylvania. I have also collected it in Cambridge, Mass., and in the 
vicinity of Washington, D.C. It occurs likewise in western North Carolina 
and in Georgia. It is of precisely the same form as S. cincta H. Schf., ef 
England and France, agreeing with that species in most of its details, and, 
upon sufficient comparison, may prove to be the same species.”—Uhler. 
Also reported from Maine, Ontario, Rhode Island, New York, New 
Jersey, Ohio, Colorado and California.
