No. 34.] HEMIPTERA OF CONNECTICUT: CICADELLIDAE. 1 29 



P. truncatus Van Duzee. 



Trans. Amer. Ent. Soc, xix, 72, 1892. 



Resembling irroratus in size and coloration. Vertex bluntly 

 angled, one-fifth longer on middle than next eye. Color pale 

 f ulvus irrorate with brown, some white spots on posterior margin ; 

 elytra white very closely and finely reticulated causing a dark 

 brown appearance. Female last ventral segment twice as long as 

 preceding, truncated posteriorly, angles rounded. Male valve 

 short, truncated, plates narrow, tips more obtuse than in irroratus. 

 Length 5.5 to 6 mm. 



This species is a grass feeder and has been taken with irroratus 

 which it so closely resembles. The genital characters of both 

 sexes will readily separate it.

P. pusillus Baker. 



Ent. News, ix, 66, 1898. 



Closely resembling and related to alius but slightly smaller, and 

 with different genital characters. Short and robust, vertex 

 obtusely angled. Pronotum very broad and short, elytra short. 

 Color pale fulvous with darker markings, vertex and pronotum 

 irregularly irrorate, elytra finely irrorate with brown. Female 

 last ventral segment almost truncate, lateral lobes only slightly 

 produced and broadly rounded, slightly concave either side of a 

 median V-shaped notch. Male valve triangularly produced, plates 

 broad at base gradually narrowed to rather blunt, incurved apices. 



Specimens have been examined from other Atlantic coast locali- 

 ties and it seems to be eastern and southern in its distribution. 

 The species occurs on short grasses. 



New Haven, 31 July, 1920 (B. H. W.) ; 22 Sept., 1920 (B. H. W.). 

 P. lobatus Osborn. 



Proc. la. Acad. Sci., v, 247, 1898. 



Small, vertex obtusely angled, slightly produced. Pale brown 

 in color, not closely inscribed on elytra. Female segment with 

 marginal lobes, and a convex posterior border between them 

 minutely notched at center. Length 5.5-5.75 mm - 



Usually found in sandy or dry areas on short grasses during 

 August. 



Branford, 28 June, 1905 (H. W. W.). 

 P. apertus Van Duzee. 



Trans. Am. Ent. Soc., xix, 76, 1892. 



Vertex with obtusely angled apex. Elytra irregularly banded, 

 often a cloud at base, a fulvous band across middle and another 

 across anteapical areoles. Head and pronotum tinged with ful- 

 vous. Female segment squarely, deeply excavated almost to base. 

 Length 6.5 mm. 



A northern form occurring throughout New England in pastures 

 and moist areas during August and September.
