12 REPORT UNITED STATES ENTOMOLOGICAL COMMISSION. 
The ravages along Platte River were chiefly felt by ranchmen (farmers), whose 
crops of vegetables in the river bottom were greatly damaged. 
C. spretun, in immense quantities, was noted on the road-crossing of Cedar Creek (an 
■eastern tributary of the North Platte), a point some 10 miles northwest from the above- 
mentioned locality on Brush Creek, on July 26, none scarcely being there on our pac- 
ing, July 18. The creek bottom is there limited — 25 yards willow undergrowth adjoin- 
ing water, and grassy area not over 100 to 150 yards from the creek's banks, upon 
•either side. The Ortkoptera did not go outside of the grassy area, beyond which, in 
every direction, extends sage-brush, the general vegetation of this part of the coun- 
try, extending from the bottoms of creeks and rivers to the foot-hills, &c, of the 
mountains, whence they spring up to what is commonly called the lower timber line. 
Mr. William Myers, hospital steward, U. S. A., referring to the lo- 
custs mentioned by Lieut. McCauley in his first communication, writes 
as follows from Fort Steele, Wyo., August 12, 1879 : 
The disappearance of the locusts toward the north was noticed on the 23d of July. 
The wind on that day was recorded: south, velocity 25 to 30 miles per hour; strag- 
glers were observed for a week afterwards ; the flight was low, the ravages committed 
in the vicinity slight, the vegetation consisting chiefly of sage-brush ; the cotton-wood 
trees forming the groves on the banks of the Platte River were uninjured. 
THE LOCUST IN UTAH IX 1879. 
The summer in Utah was very dry, as was made evident by the fact 
that the Salt Lake has fallen two or three feet since last year, and early 
in August was falling daily. A few locusts hatched out on the benches 
about Salt Lake City, within a radius of 10 miles, but did little if any 
injury to the crops. May 14, and earlier, they appeared in considerable 
numbers in Provo Valley. 
In Ogdeu Valley the young, May 21, were "exceedingly numerous," 
and even said by the newspapers to be "committing great ravages 
there," and to "have eaten the grain clear to the earth." 
At Pleasant Grove, May 24, they Avere extremely abundant, and on 
the 23d were in force at Parowan and Cedar City, Iron County. May 
25, they were abundant in and around American Fork. On the 22d of 
the same month they committed fearful ravages in grain crops at Eden. 
Weber Canon was reported, June 7, to have been stripped, the fields and 
pastures being laid bare and even the sage-brush stripped of their 
leaves. June 19 the locusts were reported to have been destroyed in 
large numbers by the fly, probably the flesh-fly {Sarcophaga carnaria), 
which always abounds wherever the young of the locust exist in unusual 
numbers. Early in June the Utah southern train for Sandy was stopped 
by locusts. According to the Salt Lake Herald, " the insects accumulated 
on the rails so thickly that the train had to be cut in two parts going 
up the grade to Sandy." 
Mr. John Lee reported, June 24, from Heber City, "that the ironclads 
are mowing everything down in that region. About eighteen or twenty 
farms were already cleaned out, and they are still at work." 
Severe suffering resulted from the ravages of the young in Morgan 
County, particularly at Croydon. Mr. C. Bunting writes us : 
This place was visited by the grasshoppers early in April last. The spring was 
wery open, and all seeds were in and up, when they appeared in swarms so small as to
