SUBFAMILY VII. — RHYPAROCHROMIN^E. 397 



neath a maple tree and was covered with plant lice, while the 

 one from Crawford County was swept from goldenrod. It is an 

 Old World species of northern distribution, occurring in this 

 country from Quebec and New England west to North Dakota 

 and Vancouver and south to New Jersey, where it is scarce. 

 Recorded also from New Mexico. According to Barber (1921a, 

 113) the Pamera contractu Say (I, 332) is a synonym of sylvestris. 

 It was first so placed by Stal (1874, 145), who also made the 

 next species, diffusus Uhl., a synonym of sylvestris. In these con- 

 clusions he was followed by Uhler, Horvath and other authors, 

 but not by Van Duzee, who, in his Catalogue, retains both con- 

 tractus and diffusus as distinct. This confusion in synonymy 

 makes it impossible to fix by previous records an accurate 

 limit to the distribution of either species. 



339 (538). Ligyrocoris diffusus (Uhler), 1871, 101. 



Elongate-oval; averaging larger and more robust than sylvestris. 

 Color much as there, but the elytra a paler reddish-brown, with the 

 transverse dark bar less clearly defined, its ends not reaching the edge 

 of costal margin of corium; hind lobe of pronotum with hind angles 

 and often three vague stripes on disk, pale ; corium with a small pale 

 spot near its inner apical angle; membrane pale brown with veins and 

 some vague markings on sides paler; legs pale reddish brown, the tips 

 of hind femora usually darker. Pronotum with front lobe much less 

 than twice the length and distinctly narrower than hind one, the diam- 

 eter at collar plainly less than that of constriction between the lobes ; 

 hind lobe and scutellum finely and sparsely punctate. Membrane reach- 

 ing or slightly surpassing tip of abdomen in both sexes. Length, 5.2 — 7 

 mm. (Fig. 69). 



Frequent in the northern half of Indiana, not taken south 

 of Marion and Vigo counties ; June 5 — Oct. 1. Taken by sweep- 

 ing tall grasses and other herbage along the margins of wet 

 meadows and marshes. Ranges from Quebec and New Eng- 

 land west to North Dakota and Colorado, and southwest to 

 North Carolina, Arizona and California. The majority of the 

 records, even by Uhler himself, have been made under the name 

 of L. sylvestris L., treated above. The two species are very simi- 

 lar in general facies, but can be readily separated by the key 

 and descriptions as given above. 



V. ORTHiEA Dallas, 1852, 580. 



Small, elongate or oblong, slender species, having the head 

 porrect or nearly so, broader across the eyes than front mar-
