Vertex sloping-, nearly rectangulate before, the sides rounded, sulcate, 
twice as long on middle as against the eye, length slightly more than half 
the width, posterior margin broadly rounding, the ocelli and suture between 
head and pronotum obscured by the heavy pubescence, ocelli equidistant 
from eyes and each other, nearer posterior margin than tylus; front moder- 
ately inflated, outline nearly straight, rostrum two-jointed scarcely equal- 
ing the front in length; pronotum with the anterior third depressed and 
on the same plane with the vertex, a row of pits along the posterior margin 
of the depressed area, side margins very short; elytra coriaceous, convex, 
the costal margin strongly curved, venation obscured, apically broken up 
and irregularly reticulate; legs very stout, spurs on hind tibia nearly twice 
as long as its width; whole dorsal surface densely pubescent. 
Color: Reddish-brown; vertex and anterior part of pronotum often tawny, 
the pubescence golden, posterior part of pronotum and disc of the elytra 
dark reddish-brown, costal margin with a light spot on middle and a larger, 
obscure one towards the apex; front varying from creamy-yellow to tawny- 
brown. 
Genitalia: Female py gofers very short and small, extending but little 
beyond the abdominal segments, strongly elevated, the ovipositer broad 
and short, nearly touching the suture; ultimate-ventral segment of the male 
abdomen larger than penultimate, slightly convex, wedge-shaped; plates 
vertical, broad, wedge-shaped, the apex rounded, much larger and shorter 
than in bilineatus. 
Habitat: Specimens are at hand from Colorado, Nebraska, 
South Dakota, and it is probable that Uhler’s reference to 
spumarius from Utah, Dakota, Sitka, and Lake Winnipeg refer 
to this species.

Form stout sub-cylindrical, the costal margins as seen from 
above, nearly parallel, head equaling the pronotum in width, 
vertex long, color pale- straw, costal margins broadly light, 
margined internally with darker; length 5.5-7mm., width 2mm. 
Vertex long, rectangulate or slightly acute, the sides sulcate, length on 
middle nearly two-thirds the width, over twice the length against eye, tylus 
half the length of the vertex, distinctly carinate, ocelli nearer the pos- 
terior margin and very slightly nearer each other than the eyes; front 
strongly inflated, anteriorly produced, outline strongly curved, the infla- 
tion equaling -the long diameter of the eye; pronotum almost flat, on same 
plane as the vertex, a median longitudinal depression the whole length, 
and two depressed spots on either side of the disc; elytra long, 
nearly parallel margined, broadly rounding behind, venation obscure on 
the disc, broken up and irregular ramose back of the middle; legs rather
