 ments of their scapes. They are very common throughout 

 the eastern section of the United States. The workers are 

 carnivorous and forage singly. They nest beneath stones in 

 the woods.

 form. They nest in rotten logs in the woods. This species 

 does not seem to be common in the northern section of the

P. morrisi Forel. 



The workers are easily separated from those of allied spe- 

 cies in having only vestigial spines on the epinotum. Their 

 nests are very characteristic, consisting of a large mound from 

 4 to 6 inches high and from 6 to 8 inches in diameter, built 

 around the base of a bunch of grass. When distributed the 

 workers run franticallv to and fro over the nest.
