Large worker ants with vestigial wings were found in certain colonies of Formica fossaceps Buren at the Iowa Lakeside Laboratory near Milford, Iowa. This paper deals with one of these colonies (49F), found on the Laboratory grounds, June 15. 1949; vestigial winged workers were present in considerable numbers in this colony. Extensive collections were made: in 1949, a total of 1414 workers, 117 (8.3%) with vestigial wings; in 1950, 9 males and 539 workers, 32 (5.9%) with vestigial wings; the colony was not found in 1951. The total number of workers was 1953, of which 119 (7.6%) had vestigial wings.
