its increase, may do great injury if it attacks fruit trees, as it undoubt- 
edly will. Almost the sole industry of the peopie of this valley is fruit 
raising, and if this species becomes abundant it will cause great trouble. 
Several years have elapsed since an orthopterological survey has 
been made in this region, which has suffered at least once in the past and 
is liable to, again in the future. I found that no damage of any con- 
sequence had been done since Professor Bruner’s visit in 1893, though 
the table-lands, mesas, and foothills harbor a number of species which 
may cause injury at almost any time. Such species are Melanoplus 
atlanis, M. bivittatus, M. differentialis, and Pezotettix chenopodii. The 
last-mentioned locust was the most conspicuous, and at one point, 20 
miles north of DeBeque on Clear Creek, had destroyed a field of alfalfa 
of small extent. This was the only case of damage that came to my 
notice. 
UTAH. 
This State was not affected by the Rocky Mountain locust this season. 
Specimens were found near Salt Lake City, in the Big Cottonwood Can- 
yon, on the tablelands eastward, and in the immediate vicinity of Echo 
in the valley of the Weber River. <A few were also taken in a waste 
field adjoining the railroad track at Cache Junction. In this State 
neither was any great damage done by the native species. Inquiry of 
farmers long residents of this region invariably brought out remarks | 
concerning the great devastation experienced in 1871, which was the 
only one in that region that they seemed to know anything about. No 
information came to me either from the officers of the experiment 
station at Logan, the State fruit-tree inspector at Salt Lake City, 
from a careful perusal of the files of the State papers, nor from the 
numerous residents who were questioned, that there was any damage 
done this season. 
I found in the vicinity of Ogden two fields of alfalfa which had been 
partially destroyed by Melanoplus atlanis Riley, but the owners had 
taken prompt action in the matter and had effectually overcome the 
pest. . 
Acridium shoshone Thos. was found damaging prune trees to a slight 
extent near Salt Lake City, at Provo and Echo. These are the sole 
cases of damage that have come to my notice, and are of very little 
Importance. 
Information reached me that hordes of Anabrus simplex were march- 
ing down one of the tributaries of the Provo River in the neighborhood 
of Park City and had done considerable damage. In that region such 
an occurrence is liable to take place almost any season, but the reports 
were so conflicting that it was not deemed best to make a special jour- 
ney on this account, since it is not an agricultural region. 
It is somewhat difficult to understand why it is that the irrigated 
regions in Utah, which are in a situation practically analogous to simi- 
lar regious in Colorado, and in which the meteorological conditions are
