is much less common than nervosa." Stoner (1920, 90) writes 

 of its occurrence in Iowa as follows : 



"Comparatively few specimens thus far obtained have been taken 

 in sweeping, most of them having been collected either late in the fall 

 or early in spring in places which they had chosen for hibernating. Indi- 

 viduals have been found under small rocks in more or less sheltered situa- 

 tions as early as Feb. 13, before the frost and ice in these places 

 had melted. During the summer these rocky places were grown up in 

 weeds and grass. On warm sunshiny days in late autumn and early 

 spring specimens may often be found walking about on the sidewalks of 

 cities. The few taken with the sweep-net were on low weeds and usually 

 in more or less moist places."

Elongate - oval, subconvex. Above brownish - yellow, thickly and 

 nearly evenly marked with fuscous punctures; antennae reddish-yellow, 

 the last joint fuscous; narrow edge of side margins of pronotum, a mi- 

 nute tooth at its front angles, and edge of tip of scutellum pale yellow; 

 connexivum fuscous, each segment with median spot and edge yellow; 

 under surface yellow with black punctures, each side with a rather broad 

 interrupted black stripe; legs yellow dotted with black; spiracles and a 

 spot at end of ventral incisures black. Head broad, rather sparsely punc- 

 tate, the margins of cheeks rounded into apex; second joint of antennae 

 nearly one-half shorter than third. Pronotum with margins broadly 

 curved ; disk sparsely but rather evenly punctate, its sides somewhat 

 flattened and with a broad vague concavity near base of humeri. Scu- 

 tellum with a smooth space and small blackish concavity on each basal 

 angle. Connexivum narrowly exposed. Length, 9 — 11 mm.; width, 5.5 — ■ 

 7 mm. 



Scarce in southern Indiana, not taken north of Marion Co., 

 Feb. 6 — Sept. 24. Hibernates as imago beneath logs and stones 

 near the borders of woods and cultivated fields. Taken in sum- 

 mer by sweeping roadside herbage. Sarasota, Fla., Feb. 18, one 

 specimen. Recorded also from Ft. Myers by Van Duzee (1909, 

 155) and probably occurs rarely throughout that State. Ranges 

 from Quebec and New England west to Nebraska and Dakota 

 and south and southwest to North Carolina, Oklahoma and 

 Texas, but, like cequalis, usually scarce where found. Uhler 

 (1876, 287) says that: "In Maryland it occurs with moderate 

 frequency upon rank low herbage in meadows and about the 

 skirts of woods. Like Euschistus variolarius and other species it 

 becomes, when senile, suffused with red, is dusted with a whit- 

 ish powder and seems then to have a more decidedly penetra- 

 tive odor in the fluid which it sprays from the aperture of its 

 glands."
