It does not even occur among the fine lot of ants kindly collected for me in the high mountains of New Mexico by Prof. and Mrs. T. D. A. Cockerell.
The subspecies diecki also occurs at Rockford under the dead leaves in the very same localities as the typical breviwrne. Often the nests of the two forms are located only a few feet from each other. The winged sexes of diecki are recorded in my notes as occurring from Aug. r 5th-I 9th. They are decidedly smaller than
the corresponding sexes of the typical form, and the male is paler, with colorless wings and paler legs and antennae. I could detect no differences in habits between die& and the typical bn-vicorne.
