March, 1922.] DaVIS : CiCADAS OF VIRGINIA. 47 



Of variety cngclhardti the following have been examined: Coving- 

 ton, 1,000 feet, August ly, 1916, female (Morgan Hebard) ; Hot 

 Springs, 2,500 feet, August 31, 191 6, male, taken from cicada-killing 

 wasp (Sphecius) by Mr. Hebard; Winchester, Frederick County, July, 

 1921, male, W. S. Hough collection. The following have been col- 

 lected in Nelson County by Colonel Wirt Robinson: July 17, 1912, 

 male; July 18, 1912, female; August 9, 1914, female; August 19, 191 5, 

 male; August 5, 1916, female; August 10, 1916, male; August 12, 1916, 

 female; July 30, 1917, female; July 31, 1917, female; August 6, 1917, 

 female; August 19, 1919, female; July 25, 1920, female. In addition 

 we dug four cngclhardti and one typical lyricen from the burrows of 

 the cicada-killer on August 6, 191 6. 



In 1921 the following were collected at Wingina: July 25, female; 

 July 31, male; August 3, male; August 7, female; August 14, male and 

 female; August 16, female; August 21, three females, and August 22, 

 male. At Johnson's Cove, near Elmington, Nelson County, August 8, 

 five females on low trees, principally small persimmons. In Bucking- 

 ham County on August 5 we found the species very plentiful in a 

 small area on Spear's Mountain, where four males and nine females 

 were collected. Three pair were in copulation and by hitting the small 

 trees on which they were, a smart crack with a club, the locked- 

 together cicadas fell to the ground. On August 11 we heard a number 

 of lyricen in that curious pile of rocks known as Willis's Mountain 

 that rises suddenly to the height of 1,159 feet from a generally level 

 country. On several occasions we found dead individuals on the 

 roads. Still later Col. Robinson, on returning to Spear's Mountain, 

 August 19, following some cool nights, found fifty-six cicadas lying 

 on the road running through the gap, nearly all of them in the gap 

 itself where the road was overhung by trees. Most of the cicadas 

 were dead, but a few were living. The majority were lyricen var. 

 cngclhardti, with two or three typical lyricen among them, while ten 

 were Tibicen linnet; no other species were found.

Figured in Howard's Insect Book under the name of tibicen, PI. 27,
