TETRAMOR1UM Mayr. 



T. caespitum Linn. Ft. Lee (Wheeler); Arlington IV, 6, New Brunswick 

 IV, 26 (Coll); Staten Island (Ds) ; Camden Co. (Dke). This is an 

 importation from Europe and is known as the "lawn ant." It is 

 spreading slowly, but will probably extend throughout the State be- 

 fore long. At New Brunswick it occurred in a greenhouse, damaging 

 some of the potted plants. 



There are three species of "Strumigenys" Sm., which almost certainly 

 occur in the State, although they have not been actually found. They 

 are "S. pergandei" Emery, "S. pulchella" Emery and "S. clypeata" Roger. 



ATTA Fab. 



A. septentrionalis McCook. Milltown, Manasquan (Ds) ; Prospertown 

 VI, 1 (Coll); Toms River (div); Lucaston (Dke); Lakehurst 

 (Wheeler); Vineland (Treat). Practically confined to the pine re- 

 gions and is the northern extremity of the range of this "cutting 

 ant." It is the only one of the fungus growing ants whose range 

 extends into the State, and its life cycle is of extreme interest. 



Sub-family DOUCHODERIN^. 



There is only a single segment in the peduncle between thorax and 

 abdomen. Sting of the female rudimentary.
