Though extremely plentiful, no marked 

 varieties occur in this species in New 

 England, the only variation worthy of 

 note being in the color of the hind 

 tibiae. These are so constantly red 

 that a locust having them colored other- 

 wise may be looked upon as almost sure 

 to belong to another species, atlanis, 

 minor, or extremus. Still, examples of 

 femur-rubru7n do occur with tibiae either 

 pale (yellowish), or even greenish or 

 blue. These are, however, extremely 

 rare. 



This is undoubtedly the commonest, 

 most ubiquitous, " gi-asshopper " found 

 in New England, occurring everywhere 

 throughout the district in every plat of 

 grass or sedge from sea-shore to moun- 

 tain-summit. The destruction caused 

 from time to time by locusts in New 



England is usually ascribed to this 

 species, and with good reason, though 

 in some cases, particularly when caused 

 by migratory swarms, it is probable that 

 atlanis is largely if not chiefly con- 

 cerned. In August, 1892, I received 

 complaints of grasshopper injuries to 

 garden crops, tomatoes, beans, etc., in 

 the vicinity of Norway, Me. These 

 proved on investigation to be entirely 

 due to this species, which was very 

 abundant locally, and no specimens of 

 atlanis could be found. It is very plen- 

 tiful at times on some of the islands off 

 shore, as I have found it on Cuttyhunk, 

 Mass., and Block Island, R. I., where it 

 had the habit, of collecting in great 

 numbers on the warm, sunny sides of 

 stone walls in the late afternoon and 

 remained over night. 



While it is almost ubiquitous it is in 

 general most plentiful in meadows and 

 the damper portions of mowinglands 

 and pastures, among the more dense 

 and succulent vegetation. 



It reaches maturity in the latter part 

 of July and is found throughout the rest 

 of the season ; I have taken specimens 

 in the vicinity of Wellesley from July 

 25 to Nov. 8.
