0. erythrocephalum Davis. 



General Range. — New Jersey to eastern North Carolina. 



Local Distribution. — Frequent in the Pine Barrens, possibly 

 extending a little into the ]\Iidclle and Coastal Districts. 



Ecological Distribution. — Apparently restricted to sphagnum 

 Ixigs, where it frequents the dense growth of chain fern, tall sedges, 

 rushes and associated plants. 



Locality Records. — 



Pine Barrens. — Helmetta (Davis) ; Jamesburg (Davis) ; Lake- 

 hurst (Davis) ; New Lisbon (Smith) ; Lahaway (Smith) ; Browns 

 Mills Junction (Daecke); Atsion (Hebard) ; Parkdale (Rehn and

0. herbaceum Serv.^fi 



General Range. — Massachusetts to Texas, along the coast. 



Local Distribution. — Common along the edges of the salt 

 marshes in the Coastal District; occasionally occurring inland in 

 the Pine Barrens. 



Ecological Distribution. — Characteristic of the zone of Scirpus 

 americanus along the edges of the salt marshes; much less frequent 

 in other parts of the Submaritime area. I have no information 

 concerning its Pine Barren habitats. 



Locality Records. — 



Middle District. — Newcastle, in Scirpus americanus (Fox). 



Canton (Fox). 



Pine Barrens. — Brookville (Davis ace. N. J. St. Mus. Rep.); 

 Da Costa (Daecke ace. N. J. St. Mus. Rep.); Speedwell (Stone ace.

General Range. — New Jersey to eastern North Carolina. 

 Local Distribution. — Apparently scarce, probably local through- 

 out the Middle and Coastal districts and in the Pine Barrens. 



26 1 am inclined to think that all N. J. specimens referred to indianense really 

 belong to this species, at least, so far as coastal material is concerned.
