The gas chromatograms of some of the volatile chemicals found in the
following ants are presented: Pogonomyrmex barbatus (F.
Smith), Forelius foetida (Buckley), Conomyrma
pyramica (Roger), Iridomyrmex pruinosus analis
(E. André), Tapinoma sessile (Say), Trachymyrmex
septentrionalis obscura (Wheeler), Pheidole
dentata Mayr, Acromyrmex versicolor (Pergunda),
and Novomessor cockerelli (E. André). The data and methods
are presented to demonstrate their potential value as taxonomic characters
in the study of ant systematics.
