Notwithstanding the remarkable form of this species, its long slender 

 antennae and legs, the prolongation of the prothorax into a neck, &c, 

 all of which appear to warrant the formation of a new genus for its 

 reception, yet, not being acquainted with either of the perfect sexes, I 

 do not feel justified in removing it from the genus Myrmica.
