Ecological Distribution. — The only individuals taken by me 

 were found in a sphagnum bog in an open spot bordering dense 

 woods. Some of the locality records would, however, indicate that 

 it occurs in other types of swamps as well. 



Locality Records. — 



Middle District. — Trenton (Grossbeck); Tinicum (Hebard). 



Pine Barrens. — Clementon (Rehn) ; Helmetta (Davis) ; Great 

 Cedar Swamp near Sea Isle Junction (Fox); Dennisville (Davis). 



0, spinulosum Redt.2" (= ? validum Wlk.) (= 1 gracile auct. non. Harris). 



General Range. — Uncertain; has been recorded from North 

 Carolina. 



Local Distribution. — Frequent locally throughout, except in 

 the Pine Barrens, which it barely enters. 



Ecological Distribution. — In open grassy or sedgy swamps; 

 especially frequent in swamps dominated by Homalocenchrus ory- 

 zoides. 



Locality Records. — 



Piedmont Plateau. — Collegeville, frequent in moist depressions 

 in meadows (Fox); Castle Rock (Rehn and Hebard); Chestnut 

 Hill (Hebard). 



Middle District. — Cornwalls (Rehn and Hebard); Tinicum 

 (Hebard) ; Elmwood, abundant in Homalocenchrus oryzoides at edge 

 of Tinicum marshes (Fox); Paschalville, in Tinicum meadows 

 (Fox). 



Riverton (N. J. St. Mus. Rep.); Lucaston (Daecke); Gloucester 

 (Hardenberg) ; Clementon (Greene); Jericho, in stream meadow 

 (Fox); Canton (Fox); Dorchester, tidal swamps along Maurice 

 River (Fox). 



? Pine Barrens. — Belleplain (Daecke, Fox), frequent in the wettest 

 parts of an extensive bog, in a tall species of Juncus, apparently 

 canadensis (Fox). 



Coastal District. — West Creek (Rehn) ; Ocean View, local in fresh 

 meadows and in the Submaritime zone (Fox) ; Sea Isle City (Haim, 

 Fox) ; Avalon (Fox) ; Piermont, in swampy depressions in the dune 



" It is possible that there may be two or three species included under this 

 name. Typical sjipcimens from Tinicum agree closely with some in the A. N. S. 

 marked spim/losuiti; others again differ slightly in coloration, and some of these 

 were tentatively referred t(} the little understood (jracile as used by authors, not 

 the gracile of Harris, which is a synonym of Xiph. fasciatum. At Bellejilain I 

 captured specimens resembling my Tinicum spitiulosum, but with a less distinct 

 ruddy tinge on the tegmina. These are j)robably the species called validum in 

 the N. J. St. Mus. Rej). They all come close to O. niqripes Scudder, l)ut differ 

 from it in lacking the characteristic black tibi;r of the latter.
