Genus Solenopsis Westwood. 



6. S. molesta Say S — Wyandotte; Pine; Veedersburg. 



A minute yellow species, with 2-jointed antennal clubs, common in open 

 grassy places where it lives in independent formicaries or more commonly 

 as a thief-ant in the walls separating the galleries in the nests of larger ants 

 belonging to the genera Formica, Lasius, Myrmica, Aphaenogasler, etc. It 

 is also known to occur in houses. The males and females are much larger 

 and of a darker color than the workers.

 Shoals; DeLong; Mt. Vernon; Bass Lake; Kosciusko County; Craw- 

 ford County. 

 A very common and widely distributed species, nesting under stones in 

 open places, under stumps, boards, the bark of old logs, etc. The workers 

 have a disagreeable odor and move about in loose files. They sometimes 

 carry the triangular gaster over the thorax with the tip directed forward.

 bat" ants.
