28 INJURIOUS INSECTS OF I9Q0Q AND IQIO. 
view of the fact that parts of Montana were formerly considered to be within 
the so-called permanent breeding grounds. I have collected within this tract 
as well as outside of it.” 
The other is from a prominent Colorado entomologist : 
“* * * Tn all of our collecting here during the past twenty years, and 
it has been quite extensive, we have never taken an example of the Rocky 
Mountain Locust, M. spretus. It is quite a disappointment to me, as I sup- 
posed I should certainly have an opportunity to collect this insect many 
times in Colorado, as Riley had given the permanent breeding-grounds of this 
insect as extending over a considerable portion of the mountains and foot- 
hills and even the plains in this state.” 
The Lesser Migratory Locust, WM. atlanis,—one we have with 
us all the time, capable, as we have seen, of doing great injury when 
occurring in large numbers, and with somewhat the same habits as 
the Rocky Mountain form,—is so closely akin to the latter that some 
entomologists regard them as almost identical, the latter possibly 
a long-winged variety of the former. The casual observer, not- 
ing them in the field, certainly could not distinguish the one from 
the other. 
Mr. Urbahns was sent into the field twice during the summer. 
His report follows: 
First trip made to Foxhome, Minn., June 38rd: Drove out to farms of 
Chas. Reber, O. L. Fuder, Geo. Sutter and G. W. Greiner. The young hoppers, 
just hatching, were very abundant, especially so on high sandy waste lands. 
Burning of meadows and idle lands was practiced wherever possible. In some 
cases this was done too early to destroy a large percentage of the young 
hoppers, and in other cases meadows were burned so late as to destroy the 
Zrass crop. 
A movement was organized to clear the fields of grasshoppers by the use 
of hopperdozers, through the joint efforts of the farmers of the entire 
locality. Mr. Chas. Reber was appointed chief in the movement. Promises 
for the construction and immediate use of eight hopperdozers were secured. 
Second trip to Foxhome, in June: Arrangements were made over tele- 
phone by which several farmers from south of town were met at the hotel. 
Two groups of farmers were met in the country at five and eight miles 
northwest of town. Fields were visited where hopperdozers were in use. 
The discussions carried on led to several changes in the construction of 
hopperdozers. Grasshoppers were apparently on the increase, but reports of 
the work were quite favorable and encouraging. A good number of hopper- 
dozers were in use, and farmers were urged to make greater use of the same. 
Rothsay, Minn.: Met four farmers at the home of Ed. Steiner, eight 
miles southwest, and then drove two miles north to meet eight farmers, who
