The species within its range is widely distributed throughout the 

 undergrowth of the long-leaf pine forests and has sometimes been 

 observed to frequent somewhat damp situations. It has also been 

 found in short grass of waste land (below fall line, Augusta), in 

 sandy tract of scrub oaks (just above fall line, Augusta), in mixed 

 oak and pine woods suggesting New Jersey pine barrens (Warm 

 Springs) and in sandy field of short grass (Atlantic Beach). In 

 central Florida the species intergrades with its geographic race 

 R. brevipenne peninsulare; north of that State the previous known 

 records for the species were Savannah, Waycross and Thomasville, 

 Georgia, and Greenville, Alabama.

Material from the Atlantic coast shows a slight increase in size 

 southward, the more robust individuals from southern Georgia and 

 from Florida have somewhat larger eyes and a broader vertex. 

 Males measure in length as follows: Anglesea, New Jersey, 19-22 

 mm.; Asheville, North Carolina (2,000 feet), 19.7-22.8; near Atlanta, 

 Georgia (1,000 feet), 19.2-21.6; Florence, South Carolina, 21.7-23; 

 Atlantic Beach, Florida, 24.3-25.3 mm. 



Five specimens are in the brown phase, two males and two young 

 from Fredericksburg and one female from Fayetteville; all of the 

 other specimens are of the more usual coloration.
