Thoracic teeth as in zmbricornis. Antennal joints as in table. Each 
joint V-shaped, the posterior branch the longer with its apex curved. 
Joints in Q serrate. ‘The joints of the hind tarsi are more slender than 
in the other species, and the pubescence is as in zmbricornis. The species 
is easily known by the number and shape of the antennal joints. Length

This species present a curiously intermediate form. The form of 
the thorax is more convex and the lateral teeth less marked, showing a 
strong tendency to the form of Homesthesis while the poriferous sensitive 
spaces of antennz and the soles of the hind tarsi (which are scarcely 
pubescent and not at all spongy) are precisely the same as in that genus. 
The first jomt of hind tarsi is shorter than in the other species and the 
posterior tibia are much more bent. Length, 1.1 to 1.5 inches = 24 to 
37 mm. Hab. Nebraska.
