OETHOPTEEA OF INDIANA. 331 



by, with both tegmina and wings absent, had more than 20 of the 

 mites clinging to the thin membrane beneath the metathorax. Old 

 and worn examples of this locust usually have the wings badly 

 damaged. 



I have combined the red-legged form femoratus with Say's older 

 yellow-legged hivittatus, as I have taken the two forms in copulation, 

 and have seen numerous specimens in which the tibise were brown 

 at base, greenish or glaucous in the middle and red on the apical 

 third. Specimens from New England labeled femoratus by A. P. 

 Morse, differ in nowise from those from Indiana, called hivittatus by 

 Prof. Lawrence Bruner. 



The yellow striped locust ranges from Hudson Bay to North Caro- 

 lina, and from the Atlantic to the Pacific. It sometimes occurs in 

 such numbers as to be highly injurious. Bruner, in one of his ac- 

 counts of this species says it is a "lover of rank and succulent vegeta- 

 tion, such as is found upon bottom lands, along the edges of culti- 

 vated fields, at the margins of woodlands and on the shaded moun- 

 tain slopes." When "it develops in large numbers, then these 

 haunts are forsaken, to a greater or less extent, and it spreads over 

 cultivated fields, eating the choicest of everything."
