in rich, rather damp woods, under stones, leaf-mould, or more rarely 

 under or in rotten logs. The colonies are very small, usually com- 

 prising less than 20, in extreme cases from 40 to 60 individuals. The 

 males and females appear Aug. 20 to Sept. 17. The larvae are 

 slender, non-tuberculate, and covered with hair. They are fed by 

 the workers on pieces of insect food, not by regurgitation. The 

 cocoons are elongate, elliptical, dark brown. The ants are very 

 timid and rather slow in their movements. When their nests are dis- 

 turbed they are at first rather neglectful of their young but eventually 

 return and carry them to a place of safety. For further notes on this 

 ant see my paper: 'The Habits of Ponera and Stigmatomma' (Biol. 

 Bull., Vol. II, No. I, Nov., 1900, pp. 43-69, 8 figs.). 



Sysphincta Roger. 



2. S. melina Roger. — This rare ant probably occurs in New Jersey 

 as it has been taken in Pennsylvania. Rev. P. J. Schmitt, 0. S. B., 

 found this and the following species under large stones in damp 

 meadows. 



3. S. pergandei Roger. — Like the preceding, and for the same 

 reason, this species probably occurs in New Jersey. 



Proceratium Roger. 



4. P. silaceum Roger. — As this species has been taken in Pennsyl- 

 vania by P. J. Schmitt and as I have taken it at Cold Spring Harbor, 

 L. I., there can be little doubt that it occurs in New Jersey. The 

 very small colonies live in rotten wood in damp, shady forests. The 

 workers move slowly and have a habit of resting on their sides. 

 The pupse are enclosed in delicate cocoons. 



5. P. crassicome Emery. — There is a single worker of this species 

 from Anglesea, N. J., in the collection of the Philadelphia Academy 

 of Sciences. 



Ponera Latreille. 



6. P. coarctata pennsylvanica (Buckley) Emery. — Camden (Fox); 

 Gloucester (Fox) ; Anglesea (Viereck) ; Glassboro (Viereck) ; Pal- 

 isades near Fort Lee (Wheeler) ; Lakehurst (Wheeler) ; Halifax 

 (Wheeler). 



This form, like Stigmatomma pallipes, lives in small colonies under 

 stones and vegetable mould and in rotten wood. It prefers rather 

 open woods where there is shade and a fair amount of moisture. The 

 males and winged females may be found in the small, irregularly
