REHN AND HEBARD 57 



It will be seen from these measurements that considerable in- 

 dividual variation is present in the general size and relative, as 

 well as actual, length of the pronotum compared with the length 

 of the caudal femur. The ovipositor is also seen to vary in length 

 individually, but this apparently is also to an extent geographic. 



Geographic Variation. — The general size shows no geographic 

 correlation but the length of the caudal femur, actual as well as 

 relative, shows an increase westward; this may be, in a measure 

 at least, environmental, as the series is too small to make satis- 

 factory deductions of this character. The same is true of the 

 length of the ovipositor. The Arkansas males and the one from 

 Southern Pines, North CaroHna, have the subgenital plate 

 more deeply and narrowly divided than the specimens from 

 Goldsboro, which may be geographic but more probably is 

 environmental or individual in explanation. 



Biological A'otes. — From the material before us it is apparent 

 that the species reaches maturity' early in June, certainh' l)y 

 June 19, our earliest exact date; the latest date in our small 

 representation is August 29. In late jNIay the species is in at 

 least one instar preceding maturity. The only datum we have 

 on the habits of the species is that, at Goldsboro, North Carolina, 

 we found it among fallen leaves of deciduous trees in a rather 

 open forest composed chiefly of short-leaf pine. In this situation 

 the species was not common. 



Distribution. — The Coastal Plain region and adjacent por- 

 tions of the Piedmont area of North and South Carolina and 

 the Ozark Mountain region of Arkansas, the distribution doubt- 

 less being continuous, although we have seen no specimens 

 from between the two regions. The most northern locahties 

 known for the species are Greensboro and Paleigh, North Caro- 

 lina, the former being the most elevated point in the eastern 

 states at which it has been taken, while it occurs at Lake Ellis 

 near sea-level in the same state. We have no exact record of 

 the occurrence of the species in South Carolina. In Arkansas 

 it has been taken as high as 2600 feet on the summit of Rich 

 IVIountain.
