P. bilineata var. infuscatus Stearns, n. var.* 



Vertex, pronotum and scutellum varying from deep clay-yellow 

 to light fuscous with a median light stripe ; in either case, anterior

 narrowly and apical areas broadly, white. 

 P. bilineata var. pallidas Stearns, n. var.* 



Pale straw-yellow; transverse ribs on front, sulcate anterior 

 margin of vertex above and below, and lateral margins of 

 pronotum, light brown.

Clastoptera Germar. 



The members of this genus in the development of the hind tibiae 

 and the structure and venation of the wings present a high degree 

 of specialization over those preceding ; and in the increased free- 

 dom of the anterior coxae and the possession of a terminal mem- 

 brane to the corium approximate the more generalized forms of the 

 Heteroptera. 



Form small, globose; extremely variable in size and color 

 markings ; head much wider than long, deflected before ; vertex 

 sloping, narrow, length on middle about one-third that between 

 eyes, slightly transversely depressed between eyes and lateral to 

 suture with tylus, anterior margin regularly rounded ; ocelli placed 

 midway between anterior and posterior margins of vertex ; eyes 

 broad, outer and posterior margins sparsely pubescent; front 

 broadly, deeply inserted into vertex, lateral margins of insertion 

 roundingly divergent, disc convex, inflated, polished, not longitudi- 

 nally carinate ; antennae inserted in deep cavities between eyes and 

 front, the basal enlargement not extending outside the cavity ; 

 rostrum short, composed of two segments, usually but slightly 

 exceeding the middle coxae; pronotum sloping, trapezoidal, 

 broader than long, disc convex, transversely wrinkled, anterior 

 margin broadly rounded, sometimes slightly produced between the 

 eyes, lateral margins short, divergent, rounding back to recurved 

 humeral margins, posterior margin deeply emarginate ; scutellum 

 triangular, convex at base, pointed at apex, narrow, length slightly 

 greater than that of pronotum before it; hemelytra narrowly to 

 broadly convex, deflected posteriorly, apices overlapping perpendic-
