localities as the Ramapo Mountains near Halifax and the sandy 

 barrens about Lakehurst. In the former locality the ants were 

 nesting under stones, in the latter under the bark of pine logs. There 

 is a vestigial tendency in this ant to construct paper-like partitions 

 in its nest, especially when nesting under stones. The workers have 

 a disagreeable penetrating odor. They ascend trees in files and are 

 much given to attending Aphides and Coccidae. The males and females 

 are very abundant in the nests at Lakehurst as late as Sept. 24. 



13. C. lineolata var. lutescens Emery. — This variety is recorded 

 from New Jersey by Emery (Beitrage, 1894, p. 282), and by Ashmead 

 in Smith's list. I have seen typical specimens from Tinicum, Pa. 

 (Viereck), which is very near the New Jersey boundary. 



14. C. lineolata var. cerasi Fitch. — Anglesea, Clementon, and 

 Riverton (Viereck); Medford (Phila. Acad.). 



15. C. lineolata pilosa Pergande. — The types of this subspecies are 

 from the District of Columbia and New Jersey. It is common at 

 Lakehurst, nesting in rotten stumps and logs near or in cranberry 

 bogs. In this locality it exhibits two interesting peculiarities, one of 

 which is as flattering as the other is derogatory to its mental plas- 

 ticity. Occasionally it constructs from particles of sphagnum moss 

 agglutinated with saliva beautiful little "cow-sheds" over the clus- 

 tered Coccidae on the twigs of Pinus rigida. These sheds are usually 

 elliptical in shape and about the size of a pecan nut or somewhat 

 larger. They are entered by a little round hole, which is never in 

 such a position as to enable the Coccidae to escape. More than a 

 dozen of these "cow-sheds" were found on one small pine tree about 

 6 feet high. Notwithstanding their ability to keep Coccidae in well- 

 constructed sheds, these ants are killed in great numbers by the 

 pitcher plants {Sarracenia purpurea). They creep into the leaves, 

 apparently for the purpose of getting at the water in their hollow 

 bases, but are unable to return over the slanting hairs which point 

 down the throats of the pitchers. In some places hundreds of these 

 ants are found in a decomposing mass in the bottoms of the pitchers 

 and probably constitute a valuable source of food to the plants.
