OTIORHYNCHIDASX—OPHRYASTINI. 43 
fourths as long as the prothorax. The latter viewed from above much 
broader than long, truncate, and of about equal width at each extremity, 
the sides full, the surface rather coarsely and very shallowly punctate. Elytra 
about two and a half times longer than broad, finely, sharply, and deli- 
cately, but not deeply, punctato-striate, the interspaces feebly rounded and 
apparently sparsely pilose. Legs short, the femora rather broad, the tibiae 
rather stout and straight. Abdomen rapidly tapering posteriorly, feebly 
and minutely punctate, the suture between the first and second segments 
(either of which is as long as the third and fourth together) slightly angu- 
late or curved, the convexity forward. 
Length, excluding rostrum, 3:°25™"; rostrum, 0°5™; elytra, 2°25™; 
breadth of thorax, 1-2". 
White river, Utah, next the Colorado line, from the very highest parts 
of the buttes. Two specimens, Nos. 898, 901, U. S. Geological Survey. 
Roan mountains, western Colorado, near the richest beds at summit of bluffs 
at head of Kast Salt creek. One specimen, No. 960, U.S. Geological Survey. 
PHYXELIS ERADICATUS. 
Pl. vit, Figs. 17, 18. 
This species, which, if the specimens here collected really belong to- 
gether, varies considerably in size, differs from the preceding, P. evigoratus, 
mainly in the greater slenderness of the elytra and their coarser and sharper 
markings. In the largest the elytron is about two and a third times longer 
than broad, with nearly straight sutural margin, very strongly arcuate outer 
margin, and subacuminate apex. There are ten punctured stric, the strice 
rather shallow and not sharp, and the interspaces smooth and broadly 
arched, but the puncta are rather coarse, tolerably deep, circular or more 
or less longitudinal, and heavier on the basal than the apical half of the 
elytron. 
The specimens are fragmentary and will hardly bear further description. 
In one the abdomen is clearly shown and it resembles that of the preceding 
species in every particular except that it is more bluntly rounded behind. 
Length of elytra, 21-41"; width of same, 0°75-1:8"™.
