The Atlantic Beach and Jacksonville series average large, the 

 Ashley Junction series shows widely different extremes in size, but 

 the average is medium, while the Yemassee, Winter Park, Wilming- 

 ton and Brunswick representations are very variable individually 

 in this respect. The Billy's Island specimens average large but 

 vary greatly, particularly in the male sex. The Albany specimen 

 is average, while the two Tybee individuals (cf) are very large. 



In the southeastern States the range of this species does not extend 

 above the fall line except where the insect has penetrated a short 

 distance up a broad river valley or, in the western part of the States, 

 has pushed in from the Mississippi valley drainage by way of the 

 Tennessee valley. 



The species was taken in a variety of habitats : in hammock and in 

 marsh about edge of same (Atlantic Beach), also in pine woods at- 

 the same locality; in pine woods, both long- and short-leaf, (Jackson- 

 ville, Sandfly, Isle of Hope, Yemassee, Winter Park, Weldon, Ashley 

 Junction and Albany); along the edge of short-leaf pine woods 

 (Columbia) ; in marshy land on the edge of hammock (Homerville) ; 

 in high bushes and "bracken" along edge of swamp (Suwannee 

 Creek); in tidal marsh (Tybee Island); in high bushes on edge of 

 swampy depression filled with gums (Wilmington); in high bushes 

 along drain near pine woods (Augusta) and from dune vegetation, i.e., 

 bayberry, oak, briars and palmetto (Isle of Palms). By comparison 

 of these data with the information given above on the phases in each 

 series, evidence concerning the habitat association of the color forms 

 can be obtained.
