glahra, is abundant, but farther up the basin, as m the vicinity of 

 Tappahannock, where the water is only sUghtly brackish, and the 

 tidal marshes occupied mostly by Scirpus americanus to the almost 

 total exclusion of Spartina glahra, it apparently becomes quite scarce.

Norfolk, September 17, 1914, July 11, 1915 (nymphs); Ports- 

 mouth, October 3; Cape Henry, September 20; Tappahannock, 

 July 25 to October 11 ; Wares Wliarf, October 3 ; Naylors, September 

 17; Sharps, October 13. 



This species, in spite of its usual occurrence within the range of 

 tidal influence, is not a true maritime form. Its favorite haunts are 

 the low damp or marshy tracts forming the border zones of tidal 

 marshes where fresh water prevails, and where the species shows a 

 marked preference for the somewhat restricted areas occupied by 

 DisticJilis spicata, but also occurs m somewhat smaller numbers in 

 the more extensive areas of Scirpus americanus and Spartina patens 

 and much less frequently in the tall reeds, Spartina cynosuroides. 

 In true salt marsh — namely, that occupied by S. glahra — it does not 

 nonnally occur. Occasionally it is taken m inland locahties; thus, 

 at Tappahannock two adult females were observed in a grassy, fresh- 

 water bog fuUy 4 miles from the river. The dominant growth in 

 this bog consisted of Homalocenchrus oryzoides, with which were 

 intermixed numerous plants of Sagittaria and Pontederia.

Franklin, September 18 (very local, apparently not common); 

 Tappahamiock, June 30 (nymphs), July 18 to October 11 (of frequent 

 occurrence, though somewhat sporadic); Naylors, September 17 

 (occasional); Sharps, October 13 (apparently local); Irvington, Sep-

 July 27 to October 31, 1914 (frequent, but rather sporadic).

Tliis species appears to be very local in southeastern Virginia; in 

 other portions of the Coastal Plain and Piedmont region visited by 

 the writer it was of very regular though somewhat sporadic occur- 

 rence. Its haunts in this region are somewhat varied, but are usually 

 in damp spots or, if in dry situations, in places where excessive evap- 

 oration is prevented by a tolerably thick cover of vegetation. As 

 noted by Morse, it is intermediate in its habitats between campestral 

 and sylvan types. In open country the writer has observed it m 

 such situations as areas of tender grass in shallow gulleys; in damp 

 depressions harboring such plants as Juncus effusus, alder bushes,
