Charlottesville, March 23 to April 19 (nymphs), April 26 to May 3 

 (male, juv.). May 17 to July 3, September 10 to October 31, 1914 

 (nymphs), February 21, 1915 (nymphs). 



Kock Fish Pass (Alton), May 30; Jarmans Gap, July 30, 1 female, 

 August 1, 1 male, 1 female. 



Woodstock, Jmie 10; Fishersville, June 12. 



Monterey, August 22, 1 female. 



Occasional, or at most sporadically frequent, in Andropogon and 

 other coarse grasses of dry, untilled areas in or near woodland, rarely 

 in open pastures of tender grass. Apparently uniformly frequent 

 throughout the State, the data on tliis point from the moimtain sec- 

 tion being, however, inconclusive as yet owing to the lateness of the 

 season at which observations were made, when only the last few sur- 

 vivors of this species were to be found. 



ARPHIA XANTHOPTERA (Burmelster). 



Portsmouth, October 3; Churchland, September 15 to October 1, 

 November 4; Deanes, September 26; Gilmerton, October 1, Novem- 

 ber 6; Deep Creek, October 1; Virginia Beach, September 20;

 Hot Springs, September 6-7. 



Moderately frequent in most localities visited, but apparently 

 quite scarce in HigUand Coimty, and even somewhat local in the 

 Rappahannock River section of tidewater Virginia wliere it was not 

 observed in a number of localities — a fact that indicates, as borne 

 out by contmuous observations at Charlottesville, Tappahannock, 

 and Norfolk, the sporadic occurrence of the species in contrast to the 

 general distribution of such common forms as Melanophis atlanis, 

 OrphuMla pelidna, etc. 



In a general way xanthoptera shows greater latitude in its choice 

 of habitats than sulphurea. Both are dry land forms and flourish 

 only in mitilled areas, but xanthoptera does not show any marked 

 preferences for woodland associations, occurring as frequently in 

 campestral stations as in sylvan. In open country it usually occurs 

 in old waste fields and pastures overrun with coarse grasses and 

 weeds, and the grassy tangles bordering cultivated fields; in wood- 

 land surroundings it frequents the low, briery scrub and coarse 

 herbage of clearings and borders.
