CALANDRIDA—CALANDPRIN.E—SPHENOPHORINI. IAT 
The elytra are long and slender, heavily ridged, and granulated. The 
mesosternum is apparently rather long, the insertion of the legs appearing 
to be equidistant. 
A single species is known, from western Colorado. 
ScIABREGMA RUGOSA. 
PE xn, Big: 8. 
Head rather short, but otherwise pretty large, apparently smooth with 
some curving ridges around the eyes; what are possibly the traces of an 
antenna show a slender scape fully two-thirds as long as the beak and a 
funicle, less distinct, perhaps as long as the scape. Prothorax very rugose, 
made up of large, rather crowded granulations, showing some tendency to 
a longitudinal arrangement, especially at the sides and on the arcuate 
frontal process; sides of front margin nearly vertical, a little oblique, at a 
little less than a right angle with the lower margin of the frontal process; 
elytra with alternating close series of tubercular ridges and plain suleations, 
the tubercles corresponding in weight to the rugosities of the prothorax, the 
whole surface also marked faintly with irregularly and indiscriminately 
scattered, shallow, tolerably coarse punctures. Femora stout, especially 
at the distal extremity, subequal, about as long as the body of the prothorax, 
the surface with faint scattered small granules. 
Length, 7"; breadth, as seen laterally, 1:97"; length of rostrum, 
125eo: 
Roan mountains, western Colorado, uppermost layers. One specimen, 
No. 91, U. S. Geological Survey. 
SCYPHOPHORUS Schonherr. 
An American type with few species, found within or near the tropics. 
Three species are recorded from the United States, but were regarded by 
Le Conte as “rather opinionative than actual.” It lias never before been 
found fossil, but I place a couple of species in this genus, though with some 
doubt, principally on account of the much more gradual forward tapering 
of the thorax and the lack of any expansion of the base of the rostrum.
