The small yeUow ants of this genus are subterranean in habit and are fond of honeydew. Ac- 

 cording to Weber (1944) all the New World species may be obligate coccidophiles. Some species 

 may be of economic importance because they tend and disperse coccids on the roots of coffee 

 plants.

 association with coccids).
