Occurs chiefly in open country, frequenting the trees, bushes, 

 weeds, and tall grasses of fields, pastures, and roadsides. Appar- 

 ently the most abundant representative of the genus in the Piedmont 

 and tidewater sections. 



AMBLYCORYPHA ROTUNDIFOLIA (Scudder). 



Jarnuin Gap, July 30, August 1 (1 male, 1 female). 



Monterey, August 16-22 (2 males, 2 females) ; Bolar, September 3 

 (1 female). 



Taken in shrubbery and undergrowth in or close to open decid- 

 uous woods. Apparently confined to the mountain sections of the 

 State. 



MICROCENTRUM i LAURIFOLILIM (Linnaeus). 



\'Miitestone, September 26 (1 male) ; Tappahamiock, September 12 

 (1 male). 



MICROCENTRUM RETINERVE (Bnrmeister). 



Charlottesville, October 31, 1915 (1 adult). 



NEOCONOCEPHALUS 2 EXILISCANORUS (Davis). 



Tappahannock, August 9 to September 10 (12 males). 



Frequent for a short period in tidal marshes (not salt), occurring 

 most commonly in tall reeds, Spartina cynosuroides, but spreading in 

 small numbers to the adjoining dry land (briery thickets, com fields). 



NEOCONOCEPHALUS LYRISTES (Relin and Hebard). 



Tappahannock, August 12 to September 13 (9 males, 1 female). 



Occasional in tidal marshes; taken most frequently on Spartina 

 cynosuroides, less frequently on Scirpus americanus. Closely resem- 

 bles the preceding species, but is distinctly slenderer and has an 

 entirely different song. 



NEOCONOCEPHALUS MELANORHINUS (Rchn amd Hebard). 



Churchland, August 8-9 (2 males). 



The writer unfom'tunately failed to note the exact spot at which 

 his specimens were taken, but it was doubtless in a salt marsh bor- 

 dering a narrow tidal stream. According to Rehn and Hebard the 

 species is confined to true salt mareh (Spartina glabra formation). 



NEOCONOCEPHALUS ENSIGER (Harris). 



Monterey, August 16 (6 males). 



This northern species was found frequenting the taller grasses along 

 a narrow ditch in a timothy pasture at the foot of a mountain ridge. 



1 In this genus the specific terms are used in the sense employed in lilatchley's Orthoptera of Indiana. 



2 The genus Conocephalus of most writers.
