42 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
allowing more than the rather small obovate transverse eyes to be seen. 
The beak is more than two-thirds as long as the prothorax, broad and equal, 
broadly rounded at the tip, with scarcely any sign of an apical expansion. 
Thorax twice as broad as long, somewhat tapering, the surface roughened 
and perhaps punctate. Elytra a little broader than the thorax, each fully 
twice as long as broad, broadly rounded apically, subequal, the surface 
very faintly scored with fine strize and profusely, finely, and faintly punctate. 
Length, including rostrum, 4""; elytra, 25™™; breadth, 2™. 
Green river, Wyoming, from the bluffs behind the town. One speci-

PHYXELIS EXCISSUS. 
Pl. vin, Fig. 16. 
The single specimen is here shown upon a side view. Its form is 
entirely similar to that of the last species, but the head is not so extremely 
short. The eye is large and circular; unfortunately the beak, partially 
seen at first, was broken and lost in attempting to work it out from the 
matrix; what was seen did not show it to differ from that of the preceding. 
The thorax is fully half as high again as long, tapering, hardly arched 
above, the surface rather coarsely and obscurely punctate. Elytra similarly 
punctate without reference apparently to the similarly coarse and somewhat 
obscure strie; they are together evidently broader than the thorax, and 
each is considerably less than twice as long as broad, rapidly descending, 
but well rounded posteriorly, moderately arched above. Femora scarcely 
enlarged, very faintly and finely striate. 
Length, excluding rostrum, 3°75"; elytra, 2°6™; height, 1:75". 
Roan mountains, western Colorado, from the richest shales at the sum- 
mit, opposite the head of Kast Salt creek. One specimen, No. 1033, U.S. 
Geological Survey. 
PHYXELIS EVIGORATUS. 
Pl. vin, Figs. 13, 14, 15. 
Head very short, nearly concealed from above by the prothorax; eyes 
rather small, circular; rostrum moderately stout, nearly equal, about three-
