Hab. New Guinea. 



I have received all tlie sexes of a species of Myrmicaria from 

 Port Natal : the female constituted my own genus Fhysatta ; the 

 workers formed my genus Septacondylus ; both must now sink, 

 and be included in Mr. Saunders's genus Myrmicaria, undoubtedly 

 the male of FJiysatta. The male has the normal iiumber of joints 

 in the antennae, namely thirteen, whilst tlie female, as weU as the 

 workers, have only seven.
