The specimens of pruinosa Say examined from Virginia have the 

 dorsum of the abdomen more or less brown in color. Sometimes there 

 is a conspicuous dorsal line of brown spots, one spot on each segment, 

 while in other individuals the hind margin of each segment is edged 

 with brown. They are without the transversely elongated and attenu- 

 ated pruinosa spot on the lateral base of the third segment, which with 

 a black shining dorsum is characteristic of typical pruinosa of the 

 general region of the valley of the Mississippi. The Virginia speci- 

 mens belong to the variety of pruinosa described as winnemanna in 

 the Bulletin of the Brooklyn Entomological Society for October, 1912, 

 from fifteen individuals collected on Plummer's Island, Maryland. 



. This insect and latifasciata have a very peculiar song, differing 

 considerably from the other native species. It has been described as 

 a rising and falling note, and may be rendered z-sape, z-zape, z-zape. 

 Sometimes the insect will hum along as if it were shut down to half 

 strength, and will then break forth again into its z-zapc song. It may 

 be heard singing during the day, but it sings more particularly at 

 evening, and an appropriate name for it would be the Evening Cicada. 

 The writer has heard many of them singing along the Potomac River, 

 also in Lynchburg, where on July 29 and 30, 1916, it was quite com- 

 mon in the back yards of the town, but seldom heard in the woods. 

 In August, 1916, it was also heard in Richmond, one at evening in the 

 grounds surrounding the governor's residence, and one in a back yard 

 along East Main Street. Dr. Henry Fox sent me a female collected 

 at Tappahannock, on the Rappahannock River, September 14, 191 5. 

 The insect is common at Wingina in Nelson County, also in places 

 across the James River in Buckingham County. The Wingina records 

 are as follows: August, 1913, male; July 11, 1915, male; August 22,
