Superfamily FORMICOIDEA 1431 



abdominalis floridanus (Buckley). N. C. s. to Fla. w. to s. Miss. Ecology: Nests are in and 

 under rotten logs and stumps, usually in damp situations. A house infesting ant, 

 especially in Florida, where it is known to nest in the woodwork of buildings and feed 

 on household foods. May also damage beehives. C. (Af.) abdominalis abdominalis (F.) 

 occurs in Central and South America. Florida carpenter ant.

Genus CAMPONOTUS Subgenus MYRMENTOMA Forel 



MyrmentoTna Forel, 1912. Soc. Ent. de Belg., Mem. 20: 92. 



Type-species: Formica lateralis Olivier. Desig. by Wheeler, 1913. 



The Nearctic forms of this subgenus nest in insect galls, in branches and stems of plants, 

 under bark of trees, in wood and buildings, and sometimes in the soU. Colonies are small, consist- 

 ing of a few dozen to several hundred individuals. The listing below essentially follows that of 

 Creighton (1950) though there will undoubtedly be some changes in the near future.

 anthrax Wheeler. S. Calif. Ecology: Nests were found in soil under large stones.

 cavities or in rotting or faulty wood.
