1905.] Wheeler, Ants of the Genus DoUchoderus. 319 



Jersey, by Mr. Wm. T. Davis. It may be the male of gagates, but 

 it differs so little from the male of marioe that I have refrained from 

 describing it. I hope to obtain the males and females of gagates 

 by a more timely visit to the pine-barrens during the summer 

 of 1906.
