Six specimens, the Jesup male, two males from Chase Prairie, a 

 Jacksonville male and the Atlantic Beach pair, have the pale lateral 

 line on the head, ventral margin of the lateral lobes and pleura 

 distinctly indicated, faint and incomplete traces of it existing in 

 several other specimens. The Jesup male is the only one having the 

 dorsal surface of the head, proriotum and tegmina faintly brownish, 

 the others, unless by evident discoloration, having this area at least 

 in part green. The three young all show a narrow dark medio- 

 longitudinal line on the head, pronotum and attingent edges of the 

 undeveloped tegmina and wings. The antennae in these are similar 

 in form to those of the adults. 



The range of this species is much more restricted than is the case 

 with the frequently associated Leptysma marginicollis. The most 

 northern record known is from Lake Ellis, North Carolina (Sherman 

 and Brimley), while southward it is unknown from any localities 

 more elevated than Waycross and Thomasville, Georgia. The species 

 is thus seen to extend over but a portion of the coastal plain and 

 southward it has been taken as far as Miami, Florida, the most 

 western known point of its occurrence being Appalachicola. 



All of the material taken by us was secured in high grasses or 

 rushes in or around swamp or marsh land, except in the Okeefenokee 

 Swamp where the species was everywhere to be found in the dense 

 green undergrowth of small saplings growing out of water in the 

 almost impenetrable swamp forest.
