OPHRYASTITES ABSCONSUS. 
PE x, Figs 1. 
This species is a little larger than either of the others and of a coarser 
structure, and apparently was densely scaled; the interspaces between the 
striz are heavily and coarsely ridged, and the punctures moderately large 
and moderately deep, the striz themselves not deeply or at least not sharply 
impressed. 
Length, 7"; breadth,.3-25™™. 
Florissant, Colorado. Three specimens, Nos. 506, 1099, 11309. 
OPHRYASTITES CINEREUS. 
Pl. vin, Fig. 12. 
The single imperfect specimen of this species (the base of the elytra is 
broken) appears to have been densely scaled like the last, but the interspaces 
are scarcely ridged, being only gently arched, while the striae are deep, 
narrow, and sharp, and the punctures still deeper and finely impressed; 
the proportions are apparently the same as in the preceding species. 
Length of fragment, 5°"; probable length of elytron, 6™™; greatest 
breadth, 2°75™™. 
Florissant, Colorado. One specimen, No. 972, U.S. Geological Survey. 
OPHRYASTITES DIGRESSUS. 
PL rx, Fig. 2. 
This species differs from the other two in the much more elongated 
form of the elytron, and in the more distinct impression, apically, of the
