Vertex sloping, disc coavex, longer than the pronotum, nearly as long 

 as the width between the eyes, margins strongly concave in the male, 

 slightly so in the female; tylus broad and distinct, the anterior margin 

 elevated: front broadly inflated, the inflation being greater than the long 

 diameter of the eye; pronotum only slightly rounded in front, behind 

 which there is a transverse row of impressed spots, the lateral margins 

 slightly oblique, as long as the eye, posterior margin short, deeply round- 

 ingly emarginate; elytra much broader than the pronotum, convex, sutural 

 margin shorter than the greatest width, costal margin extending much 

 below the level of the pronotum, broadly rounding, reflexed on the margin 

 before the middle, behind which the disc is convex, apex bluntly round- 

 ingly angulate, whole upper surface covered with a dense, prostrate, 

 golden pubescence. 



Color: Grayish or fuscous-brown, with indistinct, darker markings on 

 the elytra, as follows: A faint band from the point of the clavus, deepen- 

 ing into a spot behind the middle of the costa, sometimes traces of a band 

 from here to the apex of the scutellum, forming an indistinct, fuscous V, a 

 spot on the costa midway between the first and the apex. 



Genitalia: Female pygofers and ovipositor as broad as long, inclined 

 upwards, ultimate ventral segment only appearing as a long, triangular 

 piece in each corner: male plates convex, nearly vertical, outer margins 

 slightly narrowing, then rounding to the acute apex. 



Described from two females and seven males, from the fol- 

 lowing localities: Little Rock, Iowa (O. & B.), Squaw Canon, 

 Sioux county; Sand Hills and Dismal River, Neb. (Bruner). 



This species has several times been mistaken for^i. sorcUda 

 and is probably the one referred to as from Illinois under that 

 species, in Coding's catalogue, as the true .sordida has not yet 

 been taken this side the Mexican boundary, or very close to it 

 on the other side. The much larger size, lighter color and 

 long, sloping vertex will at once distinguish it trom.\sordida or 

 the two preceding species. 



GENUS PHILARONIA n. g. 



Stout, heavy-set, somewhat globose forms of moderate size, 

 having the form and dense hairy covering of a Lajnjronia 

 together with the sulcate vertex of a' Phlkcnus and a ramose 

 venation, which is quite distinct from the type of either genus. 



Vertex nearly rectangular in front, roundingly emarginate behind, 

 distinctly longer on middle than against eye, nearly as long as the pro- 

 notum, anterior margin between eyes and tylus deeply sulcate, ocelli near 

 the posterior margin, somewhat nearer each other than eyes, front 

 strongly inflated and coarsely ribbed, except for a narrow median zone, 

 rostrum short and stout, reaching only to the middle pair of coxje, com- 

 posed of two equal segments, head with the eyes scarcely as wide as the 

 pronotum; pronotum rather small, scarcely elevated, the anterior margin
