NO. 2176. NOTES ON VIRGINIA ORTHOPTERA~FOX. 223 



MELANOPLUS CONFUSUS (Scudder) [= M. minor of authors]. 



Tappahannock, May 25 (1 female), June 8 (2 males 1 female) (rare 

 or very local). 



Charlottesville, May 18-23 (male). May 25 to July 21 (abundant, 

 somewhat local). 



Rock Fish Gap (Afton), May 30, (abmidant), Jarman Gap, August 

 1 (abiuidant). 



Monterey, August 17, 31 (occasional). 



At Charlottesville this was the dominant grasshopper during late 

 May and early June, although rather strictly hmited to the higher, 

 drier areas and not occurring in any considerable numbers on farm 

 lands. Its choice appears to be for old upland fields and pastures 

 overrun with coarse grasses (Andropogon, Dantlionia, etc.). 



MELANOPLUS LUMDUS (Dodge). 



Charlottesville, June 20 to July 14 (nymphs probably this species), 

 September 15 to October 10, 1914, October 31, 1915 (local, apparently 

 not common). 



Jarman Gap, July 30, August 1, (local, moderately frequent). 



Monterey, August 17 to September 1; Hot Springs, September 5-6. 



The stronghold of this species appears to be in the Appalachian 

 region, where it was found in abundance along the margins of the 

 woods and in clearings on the mountain slopes. It is a typical sylvan 

 species, frequenting the grassy and shrubby undergrowth of dry 

 woodlands.. 



MELANOPLUS KEELERI (Thomas). 



Portsmouth, October 3; Deanes, September 26; Gilmerton, Octo- 

 ber 1, November 1; Deep Creek, October 1; Virginia Beach, Sep- 

 tember 20; Cape Henry, September 20, 27; Tappahannock, Sep- 

 tember 9 (2 males), 19 (3 males); Irvington, September 26, (1 male). 



This is probably a geographic race of the preceding species. It 

 appears to be rather sporadic in its distribution; usually it is scarce 

 or, at most, moderately frequent, but at Virginia Beach and Cape 

 Henry it was found to be fairly common. In its habitat preferences 

 it resembles luridus, occurring typically in the grasses and low shrub- 

 bery of dry, open woodland. 



MELANOPLUS BIVITATTUS (Say). 



Jarman Gap, July 30, (1 male). 



This specimen had the bright yeUow tibiae of the typical form. 



MELANOPLUS BIVITTATUS FEMORATUS (Burmeister). 



Tappahannock, June 7 (juv.), 17-September 12, Newtown, August 

 17 (1 female); Irvington, September 26 (1 female). 

 Charlottesville, June 13 to July 31. 

 Jarman Gap, August 1. 

 Monterey, August 22.
