Several years have elapsed since an orthopterolo^acal survey has 
been made ill t his re*]fion, which has suffered at least once in the past and 
is liable to, a^iiiu in the future. I found that no dama^ic of any cou- 
sequence had been done since Professor Bruncr's visit in ISlKi, th(Ui«,di 
the tai>h' lands, mesas, and foothills harbor a number of species which 
may cause injury at almost any time. Such si)ecies aie McJunttjtlus

last mentioned locust was the most conspicuous, and at one point, 20 
miles north ot DelUMpui on ('lear ("reek, had destroyed a tield of alfalfa

notice. 
UTAH. 
This State was not atVected ])y the Kocky Mountain locust this season. 
Specimens were found near Salt Lake City, in the l)i<^ Cottonwood Can- 
yon, on the tablelands eastward, aiul in the immediatxi vicinity of Kcho 
in the valley of the AVeber Kiver. A few were also taken in a w^aste 
held adjoining the railroad track at Cache Junct'on. In this State 
neither was any great damage done by the native 8])ecies. Inquiry of 
farmers long residents of this region invariably brought out remarks 
concerning the great devastation experienced in 1.S71, whi(;h was the 
only one in that region that they seemed to know anything about. No 
information came to nie either from the ollicers of the experiment 
station at Logan, the State fruit tree inspector at Salt Lake City, 
from a careful perusal of the tiles of the State papers, nor from the 
numerous lesidents who were (piestioned, that there was any damage 
done this season. 
1 found in the vicinity of Ogden two lields of alfalfa which had been 
])artially destroyed by MvUinojdus aiUmis Iviley, but the owners had 
taken prompt action in the matter and had effectually overcome the 
i)est. 
Acridium .sho.slione Thos. was Ibund damaging i>rune trees to a slight 
extent near Salt Lake City, at Provo and luho. These are the sole 
cases of damage that have come to my notice, and are of \ cry little 
importance. 
Inlbrmation reached me that hordes of Aii<(hn(s sl)Hitli'.r were march- 
ing down one of the tributaries of the Provo River in the neighborhood 
of Park City aiul 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 mwke a special Jour- 
ney on this account, since it is not an agricultural region. 
It is somewhat dillicult to understand why it is that tlie irrigated 
regions in Utah, which are in a situation practically analogous to simi- 
lar regions in Cohu-ado, and in \vhi('li the meteorological conditions are
