Six species of Aphididse were found in the thicket on such plants 

 as goldenrod, birch, witch hazel, elm and willow. Hamamelistes 

 spinosus Shimer was very abundant on young birch and did con- 

 siderable damage. 



In the open and semi-open spaces of the thicket, Formica exscc- 

 toidcs Forel had constructed large mounds and the inhabitants 

 swarmed over much of the nearby vegetation. Some of the mounds 

 were 21 inches high and 4 feet in diameter at the base. In the 

 dense portions of the thicket, what appeared to be abandoned mounds 

 of cxscctoidcs were noted. These were more or less grass cov- 

 ered and contained small colonies of Lasiiis umhratns minutus in
