in tidal marshes; rarely occurring in briery thickets on nearby knolls. 

 Observed ovipositing in Spartina cynosuroides. This, I understand, 

 is the most northern record of the species. 



ORCHELIMUM i AGILE (De Geer). 



Norfolk, September 17; Portsmouth, October 3; Churchland, 

 September 15-16; Gilmerton, October 1; Deep Creek, October 1; 

 Cape Henry, September 20; Franklin, November 5; Tappahannock, 

 August 10-October 9; Naylors, September 17; Sharps, October 13; 

 Millenbeck, September 27; Irvington, September 26; WTiitestone, 

 September 26. 



Fredericksbui-g, September 5 (1 male in Andropogen of upland 

 field); Charlottesville, October 31, 1915 (1 male, wet, grassy spot at 

 head of rivulet in open field). 



Usually abundant in wet or moist areas generally, especially in 

 the Scirpus americanus formation of tidal marshes and the marginal 

 fringe of succulent grasses, but never occurring in true salt marsh 

 {Spartina glabra); also common in cattail, sedgey and grassy bogs 

 inland at the head of sluggish streams. Occasionally it spreads to 

 the adjoining dry land, specimens having been taken m goose grass 

 {Eleusine indica), crab grass, foxtail grass, and Andropogon. The 

 species will doubtless be found to be better represented m the Pied- 

 mont section than the present records indicate. 



ORCHELIMUM GLABERRIMUM (Burineister).^ 



Portsmouth, October 3; Churchland, September 15; Deanes, Sep- 

 tember 26; Gilmerton, October 1, November 6; Deep Creek, October 

 1 ; Cape Henry, September 20; Franklm, September 18, November 5. 



Although I found this species quite frequent in suitable localities 

 in southeastern Virgmia, I could find no trace of it in the Rappahan- 

 nock River section of tidewater Virginia. This seems strange in 

 view of its occurrence in southern New Jersey. 



In New Jersey glaherrimum appears to be restricted to the inland 

 bogs (cedar swamps) of the Pine Barrens, but in the Norfolk region 

 it is evidently more flexible in its habitat requirements. At Cape 

 Henry, in addition to being common in the rank vegetation of dune 

 hollows and ditches, it was not infrequent in the tall bunch grasses 

 (Andropogon, Panicum amaruni, etc.) on the sm-rounding dry sand 

 dunes. Farther inland it appeared to prefer areas of stiff, but not 

 always moist, soil, occurring in the rank plant growth of ditches and 

 woodland borders and scrub. It evidently has a strong predilection 

 for sylvan surroundings. 



> The nomenclature here adopted in this and the following genus is that used by Rehn and Hebard in 

 in their recent revision ( See Trans. Amer. Entom. Soc, vol. 41, 1915, pp. 11-83 and 155-224.) 



2 This name, used by most witers in the past for the long-winged phase of vtilgare, actually belongs, 

 accordmg to Rehn and Hebard, to the O. erythrocephalwrn of Davis, which therefore becomes a synonym. 

 It was under the latter term that I included all my personal records of the present species in my list of 

 New Jersey Orthoptera, the term glaherrimum there being mistakenly applied to a form which has since 

 been described by Rehn and Hebard as a distinct species under the name superbum.
