long and slender, spurs on hind tibia small, scarcely longer than its width, 

 the apical crown of spines very large: whole dorsal surface covered with a 

 coarse golden pubescence. 



Color: Straw- yellow clouded with fuscous, margins of sulcus both above 

 and below, dark brown; vertex, pronotum and scutellum pale straw color, 

 with two longitudinal brownish fuscous stripes enclosing a narrow median 

 light one; elytra straw-yellow, the costal margin broadly white: inside this 

 is a dark stripe arising against the eye and running back across the lateral 

 margin of the pronotum and along the elytra inside the first sector to well 

 beyond the middle; sometimes in the female, often in the male, it spreads 

 out inwardly and darkens up the disc ou the anterior two-thirds; front, yel- 

 lowish, ribbed with darker; a light stripe arises under the eye and runs 

 back to join the costal stripe; legs, straw-yellow. 



Genitalia: female pygofers, short, stout, strongly elevated so that the 

 tip of the exserted ovipositer touches the sutural margin of the elytra: ulti- 

 mate ventral segment of the male abdomen very large, strongly convex, 

 shining, plates vertical, wedge-shaped, over twice longer than their basal 

 width, their tips nearly touching the elytra at the suture. 



Habitat: Specimens are at hand from Idaho, Wyoming, Mon- 

 tana, Colorado, Nebraska, South Dakota, Iowa, New Hamp- 

 shire, Ontario and Connecticut; Uhler reports it (as Uneatus) 

 from the Yukon, Mackenzie and Red River countries, and Baker 

 {asamericanus) from Massachusetts and Connecticut. 



This is a very common species on the plains and prairies 

 and extends eastward to the Atlantic coast. An examination 

 of a type of- americanus proved it to be identical with the 

 forms that have been examined from other eastern localities 

 and cannot be separated from the western ones. The only 

 point of separation given in the description is ' ' the flatter face 

 of Uneatus," and that character can be readily duplicated in 

 western specimens. 



GENUS PHIL^NUS Stal. 



Vertex with the anterior margin obtuse or slightly acutely angulate, 

 posterior margin rounding or very slightly angulate, longer on middle 

 than against the eyes, over half the length of the pronotum, anterior 

 margin between the eyes and tylus deeply sulcate, tylus distinct, anterior 

 margin rounding, polished, ocelli near the posterior margin, nearly as far 

 from each other as from eyes, front moderately inflated, coarsely ribbed 

 either side the median line, disc flattened, clothed with coarse hairs, ros- 

 trum short and stout, composed of two equal segments, not extending 

 beyond the second pair of coxa?; head together with the eyes about equal- 

 ing in width the posterior part of the pronotum; pronotum weakly convex 

 without a median carina, rounding angulate in front, deeply emarginate 

 behind, the lateral margin much shorter than the distance between the 

 ocelli, carinate, claval margins long and slightly emarginate; elytra over 

 twice longer than wide, convex or paralled margined, without an appendix;
