distal section of margin complete. 37 The ovipositor is fairly long 

 and nearly straight, somewhat elongate sublanceolate at apex, the 

 base alone showing a slight upward curvature, lateral division of 

 valves exactly at middle of sides, the apex with margins unarmed. 

 Length of ovipositor contained in length of cerci nearly one and 

 one-quarter times.

Measurements taken of a large series from St. Simon's Island, 

 Georgia, show that there is an equal or 

 greater amount of variation among indi- 

 viduals from that locality than is found in 

 the specimens whose measurements are

Color Notes. — Over the more arid portions of the range of this 

 species (which includes the type locality) the general color of the 

 insects is rather pale brown, the entire body more or less covered 



37 For variability of this character see note in '•Remarks.'
