this insect also occurred in destructive numbers in several limited lo- 
calities of southeastern Wyoming. 
At about the same time that I was investigating the northern border 
of the region occupied by the Long- winged Locust. Messrs. Snow and 
Popenoe, of Kansas, were studying it along its southern limits, where 
they found the insect in even much greater numbers than I did along 
its northern limits of abundance. As those gentlemen have made a 
much more thorough investigation of the pest than I have, and have 
written a rather full report of the results of their labors, the readers are 
referred to that paper if they desire to obtain the full particulars. 
The description, habits, distribution, and life-history of this species 
will be given farther on in this report, in connection with like particu- 
lars in reference to other species of these destructive insects which oc- 
cur in ^Nbrth America north of the Mexican boundary. 
THE LOCUST PEST IN THE EED RIVER VALLEY OF NORTH DAKOTA, 
MINNESOTA, AND MANITOBA. 
After returning to Lincoln from this Colorado trip, the Bed River Yalley 
of Xorth Dakota, Minnesota, and Manitoba was visited. In this latter 
region it was reported that the genuine Eocky Mountain Locust {Me- 
lanoplus spretus) was doing some injury to grain. Upon arriving at St. 
Anthony Park, where I expected to find the Entomologist of the Minne- 
sota Experiment Station, it was found that that gentleman was away 
from home among the grasshoppers in the northern part of his State. 
The next halt was made at Fargo, X. Dak., where my letter of instruc- 
tions suggested that I had better stop and confer with the officials of 
the experiment station located here, since they were more apt to be fa- 
miliar with the locust question so far as their State was concerned than 
would anyone else. Here also I found that most of the station workers 
were away from home engaged in active work against the locust pest. 
By lingering in the vicinity for a few days, and occupying my time 
in making collections of such species of locusts as were to be found 
about the college, I was enabled to leave at least twenty species of 
authentically labeled specimens with the authorities when they returned 
a few days later. Afterwards a number of infested localities were 
visited in company with Prof. C. B. Waldron, who had chief charge of 
the locust work in this State. These short journeys over the region 
sufficed to show conclusively that not only was the true Migratory 
Locust present, but also three other species, all engaged in the injuries 
to crops in the region under consideration. Here then, in the Bed 
River Yalley and for some distance back into the " hills" to the west- 
ward, were four distinct species of locusts present in unusually large 
numbers, while, in addition to these, a number of other species were 
by no means rare. A journey as far north as Winnipeg, in the prov- 
ince of Manitoba, showed that this region of undue increase among 
these various locusts also extended into that country for some miles be-
