28 Psyche [February 



observations made this summer, this insect is associated with the 

 bunch-gi'ass (Andropogon scoparius) and feeds on its sap. This 

 grass is often the dominant species on the sterile, gravelly soils of 

 the coastal plain of New England and is widely distributed in the 

 region inhabited by the insect. Adult insects were commonly ob- 

 served (Aug. 19 to Sept. 18, 1920) perched upon the flowering 

 stalks one to two feet from the ground. On one occasion the stalk 

 was even plucked and the bug examined through a half-inch lens 

 while still busily sucking, during which time, at irregular intervals 

 (5 to 50 seconds) it discharged from its abdomen tiny droplets of 

 a clear liquid. 



Adults have been taken in New England from the last week in 

 July till the latter part of September. They could not be found 

 this year at Wellesley in mid-October, perhaps because the grass 

 stems were then hard and dry. The young stages will probably 

 be found, if looked for, in the leafy tufts that characterize the 

 growth of this grass earlier in the season. All of the New Eng- 

 land specimens which T have seen are decidedly smaller in size 

 than those from the South.
