very considerable amount of individual variation in this respect 

 in both sexes. The smaller New Jersey individuals, however, 

 are very appreciably smaller than the smallest Cumberland Island 

 specimens. 



The ovipositor curve varies somewhat, in one extreme this 

 appendage being straighter than in others, with its dorsal margin 

 but little arcuate, while the more usual condition has the whole 

 ovipositor with its margins more regularly but not strongly arcu- 

 ate. The distal section of the ventro-external margin of the caudal 

 femora is either unarmed or supplied with from one to five spines. 

 An examination of thirty specimens, taken at random, for the 

 number of these spines shows the following:

1-0 o-o 



0-0 0-1 



0-0 1-1 



2-1 3-2 



There is a great amount of variation in the depth of the gen- 

 eral coloration, but in the vast majority the dark dorsal band is 

 indicated. The Cumberland Island and numerous New Jersey 

 specimens average dark in general tone, with generally strongly 

 contrasted pattern. When fresh many specimens from these 

 localities were distinctly thalassine in tone. 



Distribution. — Salt marsh and maritime region from western 

 Long Island, New York (Rockaway) to southern Georgia (Cum- 

 berland Island) and western Florida (Cedar Keys). It has l)een 

 recorded inland in but a single instance, that from Gainesville, 

 Florida, although two females labelled "Swansea, South Caro- 

 lina," a locality approximately one hundred miles inland, are now 

 in hand. We feel very doubtful, with our personal knowledge of 

 the habits of this species, as to the correctness of these two records. 

 The Gainesville one was reported by us when our knowledge of 

 the insect was l)y no means as full as at present, and in all proba- 

 bility the specimen reported was secured the jjrevious day at 

 Cedar Keys and accidentally confused in labelling.
