season, and it would be interesting to know whether, in the reported 
destruction to wheat, this crop bad not followed grass or whether the 
insects had not simply traveled from grass land. I have taken them 
in abundance from grass, and in blue-grass, where no other living plants 
were near, they occurred in large numbers, so that there would seem to be 
no question as to grass being their natural food. They have been 
reported as abundant and destructive on timothy in Missouri. (INSECT 
LiFe, Vol. I, p. 381). 
They are about two-tenths of an inch in length, of a brownish color, 
and the wings are rather prominently marked with dark veins. It is 
an active species, jumps and flies readily, and is easily captured in a 
sweep-net, and would probably fall an easy victim to the “hopper dozer” 
or “shield,” where these can be used. 
It was described by Professor Uhler in the American Entomologist, 
Vol. II], p. 73 (1880), and a description and an account of its injuries to 
wheat in the Carolinas and Georgia occurs in the Report of the Depart- 
ment of Agriculture for 1879. 
THE HurtruL LEAF-HOPPER. 
(Jassus inimicus Say.) 
Of all.the species of Homoptera that I have observed infesting grass 
this has been unquestionably the most abundant and constant in its 
depredations. It is par excellence a grass pest, and is found in great 
numbers in pastures and meadows at all seasons of the year, even in 
warm days of early winter, being found hopping actively about among 
the blades of grass and probably extracting some slight amount of food 
material even during this season. During the past season they have 
been especially numerous and destructive, or at least my attention has 
been called to them more frequently than before. My notes show them 
swarming in May, June, July, August, and September, and, recently, 
the latter part of November, and, later, December 12. I have found 
them scarcely less plentiful and active in the grass on blue-grass lawn. 
Lobserved them also in great numbers in all the pastures and meadows 
that I examined while in Linn County, in the eastern part of the State, 
in the latter part of June. Actual killing of grass by them is, however, 
a somewhat difficult matter to prove, and, except in seasons of unusual 
dryness, there is probably not sufficient withering of the grass from 
their presence to attract attention. In July and August grass here 
showed injury by turning brown in patches, and this commenced too 
soon after rains to be referred entirely to drought. 
Later in the summer (September.7 and later), when the attacks of the 
leaf-hopper had caused most of the lawn to appear brown, such patches 
were not conspicuous. Examination of the grass where blades were 
not entirely withered would show in many cases brown spots of varying 
sizes, generally with the center on or near the midrib, and from small
