Extract

On June 20, 1950, aphids were collected from grass on the Tantramar marshes at Middle Sackville, N.B. The aphids were causing serious damage and turning the grass brown. The writer was unable to place the aphid in a genus according to Hottes and Frison (193l), Gillette and Palmer (1931), or Baker (1923). However, according to Baker (1920) and Theobold (1929) the aphid would fall in the genus Atheroides Haliday, on the basis of the shape of the cauda. It differed from the descriptions by Laing (1920) and Baker (1920) of the genus Atheroides in that the cornicles were prominent. In February, 1955, several specimens of the aphid were sent to Mr. J. P. Doncaster, British Museum of Natural History, who (in litt.) determined the specimens as of Sipha agropyrella (H.R.L.). Dr. Hille Ris Lambers, Bennekom, Holland agreed (in litt.) with this determination.
