Only the short-winged form of this dull colored locust has 

 been taken in Indiana, and those only in Lake and Porter counties 

 on October 11 and 12. Just east of Hammond, they 

 were found in a long, low, marshy tract among the 

 leaves of blue flag. The next day they were more 

 abundant about some marshes northwest of Dune 

 Park. The males were strong and active leapers, often- 

 times giving several great jumps to a tuft of bunch 

 grass or weeds and gliding down it to the ground, 

 where they squatted close until picked up with the 

 fingers. The females were more sluggish and several 

 were taken from between the stems of grass where 

 they were standing on their heads, after endeavoring 

 to escape by diving downward. 



With the exception of a single Massachusetts rec- 

 ord, Porter Co., Ind., is the most eastern point from 

 {Atter 3 'L ug- which the species has been recorded, its range extend- 

 ing thence west and north to Ft. McLeod, B. C., Mon- 

 tana and Wyoming, and south and southwest through Texas and 

 Arizona to Cordoba, Mexico. 



In Illinois it was first recorded from Colona and Cordova by 

 McNeill (1891, 70) under the name of Pczotcttix autiimnalis 

 Dodge, a synonym. Hart (1907) mentions it also as occurring 

 along swales between sand ridges near Waukegan ; these and the 

 Massachusetts record above noted being the only ones outside of
