The genei'al sul)j(M't of grassho|)pei's has been treated elsewhere in 

 this report (see pages ()4 and VMS), l)ut two additional s|)ecies of this 

 family have been knwn to cause minor injui'ies to corn, and two 

 otliers are under suspicion.

This species (Fig. 224) is readily distinguished from 

 otlier grasshoppers of its kind by its shoi't wing-covers, 

 — only about half the hMigth of the abdomen in t he 

 female, — and by the oblong flat u])p(M' surface of the 

 thorax, sharply separate from th(> ^•ertical sides, its side 

 margins nearly straight and pai'alh^l to each otluM' aiul 

 to a median raised line. The color is eith(>r grass-gre(Mi 

 or gray-brown. It is es])eeially conuiion in central and 

 southern Illinois about the edges of woods and roads 

 and in weedy places, particularly near water. it has 

 several times been found eating corn leaves in Seiit(MU- 

 ber, and has been taken in gencM-al collecting from a 

 variety of wild ])lants and Howim-s. ( )ur earliest record 

 of its occurrence is .Inly 10, at I'rbana, and we ha\-e 

 repeatedly taken the adults at \arious dates fi-om this 

 time forward until Sej^tember 2b The eggs ai-e doubt 

 less laid in fall.

(iillette says* that this western grasshoi)i)er is rather conunon along 

 the Arkansas Hiver valley below Pueblo on moist gromid wher(> grasses 

 grow, and that it has also been takiMi in wheat and corn fields. It 

 ranges along the (>astei-n slope of the Rocky Mountains from Texas to 

 Nebraska.
