(22). A common species in open places, from 3000 ft. 
to sea-level. The formicarium is often quite large, with 
two or three thousand ants. Commonly it is under a 
stone or log on dry and more or less open ground ; im- 
mediately beneath the stone is a branching chamber. 
From this passages, 4—% in. broad, extend down irregu- 
larly several inches, with small chambers (1—1} in. long 
and an inch wide), in which larve and sometimes females 
are found. The passages and chambers are smoothly 
worked. The workers major are sluggish, and keep to 
the inner chambers; the workers minor are quite active, 
and may often be found in the daytime prowling about 
bushes. These ants are not pugnacious, even when the 
nest is disturbed. The workers major are much less 
numerous than the workers minor, perhaps one-fifth of 
the whole colony. Occasionally the nest is made in 
rotten wood, or under rubbish.
