IOWA ACADEMY OP SCIENCES. 
Vertex slopiag, disc coQvex, 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 flrst and the apex. 
Genitalia: Female py gofers 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 L. sordida 
and is probably the one referred to as from Illinois under that 
species, in Goding’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 from 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 Lapyronia 
together with the sulcate vertex of a PMloenus 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 coxae, com- 
posed of two equal segments, head with the eyes scarcely as wide as the 
pronotum; pronotum rather small, scarcely elevated, the anterior margin
