We are certain that Scudder has correctly synonymized Tridactylus 

 histrionicus and T. histrio of Saussure, 1896, under the present species. 

 All of the large series before us show the presence or absence of minute 

 subapical natatory lamellae on the dorsal margins of the caudal 

 tibiae to be due to individual variation. The maximum number of 

 these in the present species is two on the external and one on the 

 internal margin, a feature noted by Saussure in his description of 

 histrio, while his histrionicus represents material lacking these 

 rather rudimentary appendages ; minuta was at that time overlooked 

 by Saussure. 



But one specimen in the series here recorded, from Spring Creek, 

 Georgia, is macropterous; the larger series before us show occasional 

 specimens in this condition, some which are semi-macropterous, 

 while many, as in the present series, have the wings wholly concealed 

 by the tegmina. 



This insect is found on wet sand near water, often in great numbers, 

 over the entire territory at present under consideration.

This species was described from the "Atlantic States, from Mary- 

 land southward," it has since been recorded from Washington, 

 District of Columbia, and Georgia, over the area here considered.
