1. Formica fuliginosa, Lat. Black Ant or Eramet. 



The neuters are occasionally met with in the 



woods, but the males and females are rare. 

 2 F. nigra, Linn. Garden Ant. Common, especially 



in the greenhouse, where they may be observed 



milking the Aphides.

of eating unripe fruit in the kitchen garden, 

 and also of being under bark.

neuters of this ant in the stump of a tree, in 

 the hedge, between the Eweleaze and Brook 

 Furlong, in 1872.
