100 NORTH AMERICAN ACRIDIDAE (oRTHOPTERA) 



and coloration are unusually protective in character. As is 

 usual with such forms of insect life, it is not particularly active. 

 The species is also found, however, among grasses in open areas, 

 along the borders of forests and in damp situations. 



Over the greater portion of its distribution hrevipenne brevi- 

 penne is a spring form, frequent immatures, but adults almost 

 never, being met with, after midsummer. In the southern por- 

 tion of its distribution, however, like its more southern race, it 

 is to be found adult both in Spring and Fall, and is probably 

 present in that stage throughout most of the year. 



The northern limit of distri])ution of typical hrevipenne, as now 

 known, runs through Yemassee, South Carolina; Augusta, Macon 

 and Warm Springs, Georgia; Montgomery and Selma, Alabama; 

 Agricultural College and Jackson, Mississippi. It is probably 

 limited in western distribution by the eastern escarpment and 

 delta country of the Mississippi River. In peninsular Florida 

 it is found typical as far south as Palatka, Ocala and Dunellon.
