In the Rappahannock River section all specimens were foimd on 

 the sandy beaches of broad, tidal estuaries, where this species is 

 usually associated with Psinidia, and, like the latter, in areas char- 

 acterized by the presence of sand bur, CencJirus. In southeastern 

 Virginia it appeared to be of frequent, though somewhat local, 

 occurrence inland, inhabiting there open sandy fields and footpaths. 

 Appears to avoid locations where there is any considerable cover of 

 vegetation. 



TRIMEROTROPIS MARITIMA (Harris). 



Virginia Beach, August 9 (adults, nymphs), September 20; Cape 

 Henry, Septcimber 20, 27; Naylors, September 17, 1 male; White- 

 stone, September 26, 1 male, 1 female. 



Frequent on sand dunes of sea beaches, commonly associated with 

 Aminopliila arenaria; occasionally occurring on sandy shores of tidal 

 estuaries. At Naylors the smgle s]iecimen taken occurred in an area 

 supporting CencJirus. 



Subfamily Acridiinae. 



LEPTYSMA MARGINICOLLIS (ServUIe). 



Portsmouth, October 3; Churchland, November 4 (1 female); 

 Deep Creek, October 1 ; Cape Henry, September 20, 27 (13 adults, 1 

 nymph); Tappahannock, April 24 (1 female in Andropogon), 25 (1 

 male m Andropogon), July 18 (1 male), August 2 (juv.), 12 (juv.), 

 13 (male adult, nymphs), 18-October 11; Naylors, September 17; 

 Sharps, October 13; MiUenbeck, September 27; Irvington, Septem- 

 ber 26. 



Common locally in tidal marshes, where it occurs most frequently 

 in the areas of Scirpus americanus, largely avoiding the true salt 

 marsh grass, Spartina glabra; not imcommon in grassy or cattail 

 bogs inland at the head of tidal streams or in the grassy thickets bor- 

 dering sluggish streams (Deep Creek) not far from the coast. Occa- 

 sionally spreading from the marshes to dry upland fields, where ex- 

 amples have been taken m Andropogon. So far the species has been 

 observed in the latter only in spring and late fall. It is evident 

 from the records given that the adults or nymphs survive the winter.
