Psyche 
[December 
with the larger abdomen, was paler in color than the workers, 
with higher petiole and more pubescent legs and gaster. He 
regarded this individual as an ergatoid female and the other as a 
form transitional to the normal worker. That he was correct 
in his assumption is shown by the foregoing observations on 
kirki. Whether such ergatomorphic females ever co-exist with 
winged forms in the same species or colony will have to be de- 
termined by future observations.
