No. 34>] HEMIPTERA OF CONNECTICUT I CERCOPIDAE. 229 



Genitalia : Female, last ventral segment convex, one-half length 

 of preceding; pygofers short, stout, outer margins broadly curved, 

 exceeded by broad ovipositor one-third their length. Male, last 

 ventral segment convex, larger' than preceding ; plates broad at 

 base, vertical, wedge-shaped, apically rounded ; male structures in 

 toto more compact than in bilineata. 



Color: Reddish-brown; vertex and anterior third of pronotum 

 often varying to tawny, with a coarse, long, golden pubescence ; 

 remainder of pronotum and elytra deep reddish brown, the costal 

 margins and a larger, obscure area near apex, lighter. 



Distribution: Specimens have been examined from Colorado, 

 Nebraska, and North Carolina. It has been reported from South 

 Dakota (Ball). 

 P. bilineata (Say). (Fig. 20, 64-67.)

Form narrower and more elongate than that of the preceding 

 species ; width across costal margins of elytra slightly greater than 

 at eyes ; color clay-yellow variably marked with fuscous. Length 

 5-7 mm. ; width 2-2.5 mm - 



Vertex long, length on middle two-thirds width and greater 

 than length of pronotum behind it ; tylus narrowly rounded before, 

 length greater than width and equal to length of vertex behind it; 

 ocelli slightly nearer each other than eyes ; pronotum, disc flat- 

 tened, weakly convex, two depressed spots lateral to weak median 

 longitudinal depression, posterior margin broadly emarginate ; 

 elytra long, parallel-margined, broadly rounded behind. 



Genitalia: Female, last ventral segment short, anteriorly 

 strongly incurved in median line; pygofers, length equal to width, 

 outer margins obtusely angled, exceeded by ovipositor one-third 

 their length. Male, length of last ventral segment twice that of 

 preceding, strongly convex, shining; plates vertical, over twice 

 longer than their basal width, inner margins attingent, outer 

 margins strongly sinuate and narrowing from base to small black 

 tips. 



Color : Typically clay-yellow variably clouded with fuscous ; 

 two longitudinal stripes enclosing a lighter one from anterior 

 margin of tylus medially across vertex and pronotum, and along 

 suture of elytra sometimes to apex, stripe extending from eye 

 across lateral margin of pronotum, slightly inside of outer sector 

 of elytron and fading posterior to middle, sulcate anterior margins 

 of vertex above and below, fuscous ; costal margins of elytra 

 dusky white. 



Two extremes in coloration occur, linked to the typical form 

 bilineata by a complete series of gradational variations, for which 

 I propose the following variety names :
