While on an ant-collecting trip to Pelee Point, Ontario, August 6, 1931, with Dr. Mary Talbot, Miss Mable Schramm and Prof. Merle G. McFadden, the writer found a queen (Coll. No. 526), the first specimen of this new Solenopsis. The striking rose pink color of the gaster was a shade of red we had not found before in any of the ants of this region.
