OSBORN AND BALL THE GENUS PEDIOPSIS. II7 



patches on a milky sub-hyaline ground in female, deep reddish brown 

 in male. Length, ? 4-75-5 mm; J, 4.50mm.; width, 1.50 mm. 



Pronotum obtusely angled before, rugae coarse, rather broken and 

 somewhat curved around the polished area just inside either eye, 

 these areas and sometimes the margins yellowish, disc rusty brown, 

 scutellum very variably marked, often entirely brownish. Elytra 

 longer in the female than in triinaculata, milky sub-hyaline, irregu- 

 larly washed with rusty brown, deepest on the base; in the male of a 

 deep nearly uniform reddish brown, face ) ellowish green sometimes 

 washed with brownish, a spot on the propleura in the male often ob- 

 scured by the brown color below. 



This species has only been received from Colorado. It varies much in 

 depth of color, sometimes even approaching trimaculata from which 

 it may be readily distinguished by the longer and more pointed elytra 

 and the absence of the light spots. 



Pediopsis ferruginoides V. D. (Plate If., Fig. 4.) 



Pediopsis ferruginoides V. D. Review, Ent. Am., V., i8r, 1889; Cat , p 

 260; Osborn & Ball, Dav. Acad. Nat. Sci., VII, p. 66, 1898. 



Pediopsis bifasciata Gillette & Baker. Hemip. Colo., p. 73, 1895. 



Light or dark ferruginous, a transverse hyaline band on the elytra 

 including the cross nervures at the bases of the anteapical cells. 

 Length, ? 5- 50-6 mm.; d^, 5 mm.; width, 1.80 mm. 



Pronotum nearly right-angled before, rugae coarse but rather shal- 

 low and inconspicuous, elytra rather long and narrow, apex acutely 

 rounding. Color: face, pronotum and scutellum usually light ferrugin- 

 ous. Elytra usually a dark reddish brown, with the hyaline band in 

 strong contrast. In some of the females the elytra are scarcely darker 

 than the pronotum while in others and in most of the males the pro- 

 notum, excepting a light spot behind the eyes and the upper part of 

 the face, are nearly as dark as the elytra, all below some shade of yel- 

 low, propleura usually with a large spot in both sexes. 



Habitat, Montana, Colorado, Nebraska and Iowa. Occurs on the 

 narrow-leaved willows, adults from the middle of June until the mid- 

 dle of July. The specimens from which the species was originally 

 described were both of the lighter-colored females. The majority of 

 the females, however, are much darker, as are all the males. The 

 Colorado specimens reported as bifasciata were faded examples of this 

 species.
