774 PROCEEDINGS OF THE ACADEMY OF [DeC. 



THE] ORTHOPTERA OF THOMAS COUNTY, GEORGIA, AND LEON COUNTY, 



FLORIDA. 



BY JAMES A. G. REHN AND MORGAN HEBARD. 



The material on which the following study is based comprised over 

 three thousand specimens, of ninety-four species. The majority of 

 this extensive series is contained in the collection of the junior author, 

 but a thoroughly representative series is in the collection of the Acad- 

 emy of Natural Sciences of Philadelphia, part being collected by Rehn 

 and part presented by Hebard. 



The series studied contains material taken on dates extending from 

 December, 1902, to April, 1904. The junior author resided at Thomas- 

 ville from December, 1902, to May, 1903, and from late November, 

 1903, to early April, 1904. During the summer of 1903 a collector 

 was employed to work in the vicinity of Thomas ville, and a very good 

 series of the summer and early autumn species obtained. The senior 

 author spent from March 14 to April 5, 1904, with Mr. Hebard and 

 they together examined considerable of the surrounding country. 

 Several trips were made over the State line into Leon county, the 

 adjoining portion of Florida, one in 1903 and two in 1904. 



The critical portion of the following paper is almost entirely the work 

 of the senior author, while the field notes, which are followed by M. H., 

 are the work of the junior author, but the}^ agree in all the state- 

 ments made. 



As a general description of the country is usually of great value in 

 a faunistic paper, we have summarized the principal features of the 

 region under consideration and also made some notes on the occurrence, 

 time of abundance and local environment of a number of the more 

 interesting species of Orthoptera. 



Thomasville, Georgia, the county seat of Thomas county, is situated 

 in the southwestern part of the State, some twelve miles distant from 

 the Florida line and about fifty miles from Alabama. The surrounding 

 country is gently rolling and covered with fine pine forests, and divided 

 into large plantations, many of which have the greater part of their 

 area cleared and under cultivation, the chief crops being corn and 

 cotton. Sweet potatoes, sugar cane and peanuts are also extensively
