1. Myrmica molesta. Say, Bost. Journ. Nat. Hist. i. 293. 6. 

 I have carefully examined several individuals of the worker of this species 

 from Makassar, and compared them with specimens obtained from 

 North America, Brazil, and from houses in London, and can detect no 

 specific difference; the examples from Celebes are paler at the apex 

 of the abdomen; beyond this, I see no difference. I consider M. 

 molesta a cosmopolitan species, which has been carried in merchandize 

 to all parts of the world.
