Crematogaster Lund. 



C. lineolata Say. 



A very common species, nesting under stones in open places, 

 under stumps, boards, the bark of old logs, etc. There is a vesti- 

 gial tendency in this ant to construct carton partitions or cells in 

 its nest or over aphids and coccids on plants. The workers, 

 which have a disagreeable odor, move about in loose files and 

 often carry the triangular gaster over the thorax with the tip 

 turned forward. The males and winged females may be found 

 in the nests from the latter part of July to September.
