102 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



Apparently an imported species occurring on Japanese and 

 sugar maples, and perhaps other species of the same group. Quite 

 abundant both as nymphs and adults in June and July. They seem 

 to be more abundant on the higher branches and only a few occur 

 on the lower foliage of the same tree.

P. acutus (Say). Jassus acutus Say. (PI. ii, 3.) 



Jour. Acad. Nat. Sci., Phila., vi, 306, 1831. 



Brown, vertex acutely angled, almost twice as long as width 

 between eyes, marked with longitudinal pale areas. Pronotum 

 with longitudinal vittae, elytra with numerous dark costal veinlets 

 and apical areoles. Face yellow, fuscous margined. Length 

 5 mm. 



A very common species throughout the summer on grasses in 

 meadows and pastures, and frequently abundant on blueberry in 

 boggy areas. It is of economic importance because of its numbers 

 and variety of food plants.

P. cuprescens Osborn. (Fig. 9, 13a, b.) 



Rept. N. Y. St. Ent, xx, 517, 1905. 



Vertex long, sharp, more than twice longer than wide between 

 eyes, side margins often paler in color, cuprescent, elytra heavily 

 infuscated, with few areolar spots, most of which are on apical 

 and anteapical cells. Face pale, very slightly and gradually 

 darkened at margin. Length 4.5-5 mm. 



A common form in shaded and wooded areas, occurring on 

 ferns and undergrowth in a moist habitat. June to September. 

 P. angustatus Osborn. 



Rept. N. Y. St. Ent, xx, 518, 1905. 



Vertex almost one-half longer than width between eyes, greenish 

 with longitudinal dark markings. Elytra greenish with yellowish 

 tinge; costa hyaline with dark veinlets, areolar spots confined to 

 apical and anteapical cells. Veins on apical portion heavily 

 infuscated. Length 4 mm. 



Described from Long Island, N. Y., and no doubt its distribution 

 extends northward and into Connecticut. It often occurs in the 

 brake-fern habitat in open fields or cut-over areas during August, 

 and is a distinctly northern species.
