A familiar object about Carices everywhere east of the Rocky 

 Mountains, and must be common in suitable locations in Connecti- 

 cut. These insects and the Cymus found with them mimic the 

 chaff of the Car ex so perfectly that they are hard to detect when 

 seen together in the collecting net.
