22. S. (A.) treatae Forel. — The types of this species, which is 

 readily recognized by the remarkable lobe on the base of the antennal 

 scape in the worker and female, were taken by Mrs. Mary Treat at 

 Vineland. I have seen many colonies in the pine barrens about 

 Lakehurst. The nests, which are not readily found, except by fol- 

 lowing foraging workers, are in the sand in the shade of the oaks 

 and pines. The entrance is sometimes produced upwards in the 

 form of a little chimney and the earth or sand pellets removed by the 

 ants while excavating the galleries are scattered about over a circular 

 area 8 to 10 inches in diameter. The workers are very cowardly. 



23. S. (A.) lamellidens Mayr. — A few colonies, found at Lake- 

 hurst, were nesting like the preceding species in rather shady places. 

 Two isolated females were discovered in the act of establishing their 

 formicaries in little cells about 3 inches below the surface of the sand. 

 In one of these incipient nests there were a few larvae and pupag, in 

 the other a few diminutive workers. 



24. S. (A.) fulvum Roger. — Recorded from Caldwell (Cresson). 

 I have always taken this the typical form of the species in rotten wood 

 in rather dense forests. It is much less common than the following 

 subspecies and variety. 



25. S. (A.) fulvum aquia {Buckley) Emery. — Anglesea (Viereck); 

 Clementon (Viereck) ; Westville (Phila. Acad.) ; Jamesburg (Davis) ; 

 Halifax (Wheeler). 



This form occurs under stones in shady woods, often in the same 

 stations as the following variety. 



26. S. (A.) fulvum aquia var. piceum Emery. — Very common in 

 shady woods along the Palisades; also in the Ramapo Mountains, 

 about Halifax. Careful studies of the habits of this ant have been 

 recently published by Miss Adele M. Fielde in a series of papers. 1 



Myrmica Latreille. 



27. M. punctiventris Roger. — Camden (Smith's List); Riverton 

 (Viereck); Medford (Phila. Acad.); Fort Lee (Wheeler). 



The worker of the typical form of this species is dark colored and 

 has apically deflected epinotal spines which are longer than the 

 epinotal declivity. The sculpture of the head, thorax, and pedicel 

 is very coarse. The species, which is by no means common, nests in 

 small colonies under stones in moist, shady woods. The males and
