about Gehring as a center; South Platte to North Platte (100 miles of 
the North Platte Valley before the junction with the Platte has been 
exempt), Chase, Dundy, Hays, and Hitchcock counties in Niobrara 
Valley, Chadron, and from Ainsworth to Neleigh. 
The species concerned in the damage have been, in order of their 
abundance, the differential locust (MW. differentialis Thos.), the lesser 
_ migratory locust (M. atlanis Riley), the two-striped locust (M. bivittatus 
Say), and the red-legged locust (MW. femur-rubrum DeG.). ‘The remark- 
able point in this connection is the searcity of the long-winged locust 
(Dissosteira longipennis Thos.), which was very noticeable last year and 
was supposed to show indications of becoming very troublesome. It 
caused practically no damage except at one isolated point near Ogal- 
lala, An equally remarkable fact was the increase at some points of 
Hippiscus corallipes Hald., which, like D. longipennis, up to within 
three years was extremely rare, and is so recorded in Professor Bruner’s 
list of Orthoptera published last spring. This large species was found 
at Sidney, North Platte, and some other points in abundance. It has 
never before been known to cause injury. J. angustipennis Dodge, 
and J. faedus Scudd., as well as other species of destructive tendencies 
have, as far as I have found, been at a standstill. In this State I found 
no fungus or bacterial disease abundant enough to affect the situation 
except locally. Tachinid parasites were extremely numerous at Cul- 
bertson, Sidney, and Indianola. 
KANSAS. 
The Rocky Mountain locust, Melanoplus spretus, was practically 
absent from Kansas this season, although some few specimens have 
invaded the northern part of the State and deposited their eggs during 
September. These will undoubtedly not be heard of next season. 
In the western third of the State the valleys of the Solomon, Arkansas, 
and Cinnamon rivers have been generally affected by the non-migratory » 
Species, and the damage has been intensified in the northwestern and 
southwestern corners of the State along the tributaries of the Repub- 
lican and the main valley of the Arkansas. During the month of Sep- 
tember this latter region was affected so severely that application for 
help was made to the Kansas State board of agriculture at Topeka, and 
the University of Kansas has issued a bulletin on the subject. The 
counties that have been most affected are Rawlins, Decatur, and Norton 
in the northwestern part, and Hamilton, Kearney, Finney, Morton, and 
Grant in the southwestern part. The remainder of the western part 
seems to have been infested with scarcely more than the normal number 
of locusts. The reasons for this state of affairs are precisely the same 
as those for the conditions in Nebraska, and the pest might as easily 
be removed by proper means. 
The species concerned are practically the same as those in Nebraska, 
Melanoplus differentialis doing at least three fourths of the damage,
