Vertex, sloping or transversely depressed, about one-fourth longer on 

 middle than at eye, anterior margin moderately thick, nearly straight to 

 the tylus: tylus moderately produced and rounded, fully twice wider than 

 long: front moderately inflated, the inflation equaling the long diameter of 

 the eye, produced anteriorly, forming a right angle with the vertex; pro- 

 notum somewhat depressed before the middle, disc elevated, the lateral 

 margins about equaling in length the distance between the ocelli: elytra 

 long and narrow, exceeding the abdomen: costal area less than one-half 

 wider at the angle of sector than opposite the discoid cells. 



Color: Vertex tawny, punctured with darker, carina light; pronotum 

 grayish, coarsely punctate with tawny or rusty-brown; elytra tawny or 

 grayish-brown, coarsely punctate with darker: an oblique, light band from 

 the scutellum to the center of the corium, another from before the apex of 

 clavus, running transversely on to the corium, then obliquely back to the 

 costa, both bands broadly dark margined, the anterior one emphasized on 

 the costa. 



Genitalia: Female pygofers and ovipositor short and compact, thickly 

 set with coarse hairs: ultimate ventral segment of male abdomen longer 

 than its basal width, narrowing apically; plates in the form of long, taper 

 ing, finger-like processes, attingent until just before the black tip, where 

 they narrow slightly and diverge. 



Habitat: Specimens are at hand from Vancouver's island, 

 Washington, Oregon, California, Idaho, Montana, and Colo- 

 rado, and Uhler reports it from Utah.

Fulvous or grayish-brown, a broad, median light stripe 

 across head and pronotum, and oblique, light bands on the 

 elytra; smaller than either' para ZZe^a of" permutata , and with a 

 less inflated front; length 3.5-lOmm., width 3-3. 5mm. 



Vertex, nearly flat, anterior margin thin, confluent with that of the tylus, 

 w^hich is also carinate anteriorly, making the entire anterior margin of the 

 head thin and rounding, parallel with the posterior margin: front small, 

 outline a regular curve, inflation less than the long diameter of the eje: 

 pronotum only slightly convex, transverse depression before the middle 

 very slight, carina weak, except across the depression: elytra moderately 

 long and narrow, slightly exceeding the ovipositor in the female, costal 

 margin scarcely reflexed. 



Color: Vertex, fulvous with a broad, median light stripe: pronotum 

 fulvous in front, grayish behind the middle, a broad, median light stripe, 

 creamy yellow in front, broader, paler and including a few dark 

 punctures behind the middle: elytra fulvous or grayish-brown, with the 

 oblique, light bands broad and indistinct, rarely margined with darker. 



Genitalia: Female pygofers half longer than their basal width, 

 exceeded about one millimeter by the ovipositor, which is scarcely
