at top of bluffs opposite head of East Salt creek. Three specimens, Nos. 
1007 and 1008, 1017 and 1018, 1027 and 1028, U. 8. Geological Survey. 
White river, Utah, from the highest summits of the buttes next the Colorado 
line on the northern bank. One specimen, No. 962, U.S. Geological Survey. 
The measurements of the interspaces between the elytral striz given 
in the original description are twice too large. 
HORMORUS Horn. 
A genus founded on a single species from eastern North America, still 
the only one known. ‘To it I have referred a single fossil from Florissant.

Provisionally, until further material is obtained, I place in this genus a 
species which seems to belong here or in its near neighborhood from the 
structure and relations of the posterior coxee, the straight suture between 
the first and second abdominal segment, the length of the antennal scape, 
the form of the rostrum, and the general facies; but the length and slender- 
ness of the funicle of the antennze, and indeed of the scape as well, indicate 
that it should be placed outside of it but in the near vicinity; the third 
and fourth abdominal segments also are together somewhat longer than the 
second. The single specimen is, unfortunately, not very well preserved, 
but shows the following characteristics: Head smooth, with delicate, trans- 
verse, curving rugze; rostrum (incorrectly rendered on the plate) straight, 
declivent, nearly as long as the thorax, stout, being fully half as high as 
long, equal or subequal, finely granulated, the apex rounded; eyes rather 
small, rounded, not over a third as broad as the rostrum. Antenne very 
slender throughout, the scape enlarged apically but not coarsely, attaining 
the middle of the eye; funicle exceedingly slender and equal, nearly as 
long as the head and rostrum together, the club lacking. Prothorax sub- 
cylindrical, equal, without tuberosities, minutely rugulose. Elytra poorly 
preserved, but with series of indistinct circular lenticles, probably casts 
of rather weakly impressed puncta.
