The original description follows: 



General form of P. concaua Say, but more decidedly vertical in front, and 

 with the dorsal outline scarcely depressed before the middle; apex of the pro- 

 notum more slender and acute. Color pale yellow; the head and fore part of 

 pronotum clouded with pale brown; a spot above the humeri, a broad obhque 

 band behind the middle, and a broad cloud on the apex grayish brown; the 

 dorsal edge irregularly spotted with dark brown, and the oblique band sur- 

 mounted by a large brown spot. The surface closely beset with series of coarse 

 sunken jjunctures; the longitudinal and reticulated surface lines obsolete. 

 Humeral margin of the sinus waved. Under side piceo-testaceous; the front, 

 clypeus, pectu.s and venter, excepting the edges of the segments, black-piceous. 

 Legs dull yellow, closely pubescent, clouded, and spotted with brown. 



Length, 4 to 4% mm.; breadth of pronotum, 2 mm. 



Colorado (C. Thomas) ; also discovered in Utah, Dakota, Arizona, New 

 Me.xico, Cahfornia. , 



In two specimens examined, the commonly raised lines on the surface of the 

 pronotum were obliterated. 



Distribution. Besides the above localities specimens have been 

 taken in Kansas in Gove and Trego counties. 



Hosts. Gillette and Baker report this species on Solidago, alfalfa, 

 Helianthus, Iva, and Artemesia. Goding gives Glycyrrhiza lepidota 

 and mesquite as hosts.

Funkhouser gives the following technical description: 



Varies greatly in color and somewhat in shape, particularly in form of dor- 

 sal sinuation; color varies from gray to black; dorsum convex, tectiform, 

 faintly ribbed, dorsal sinus shallow; pronotum irregularly ridged, deeply punc- 

 tate; tegmina largely co\ered by pronotum, basal half of each costal area 

 strongly punctate. 



Head slightly projecting, strongly punctate with black; base nearly straight; 

 inferior margin I'ounded; ej'es not prominent; ocelli prominent, usually red- 

 dish; clypeus rounded, very wide at tip. 



Pronotum deeply, densely and coarsely punctate, lateral areas marked with 

 high, distinct, irregular, longitudinal ridges; dorsal margin sinuate just be- 

 hind humeral angles, sinuation usually very shallow; posterior lobe gradually 

 elliptical to posterior apex; posterior process heavy, high, tectiform, blunt, ex- 

 tending just beyond. tips of tegmina.
