Postscript. 



After the manuscript of this paper was completed Mr. Frederick 

 M. Gaige wrote me that he had taken a female of Eciton vagans Olivier 

 in the Arroyo de Arena, at an altitude of 400 ft., in the Santa Marta 

 Mts. of Colombia, on August 25, 1920. Dr. Carlos Bruch also sends 

 me word by Prof. J. C. Bradley that he has recently captured a 

 female of Eciton (Acamatus) stroheli Mayr in the Argentine. Thus 

 the number of species of which all three phases are known is increased 

 to eight.
