In these Proceedings for 1953 (p. 656) we discussed the duration of nets of Formica obscuripes Forel. We now have data for two additional years which establish certain facts only indicated earlier. The survey was started during the summer of 1945 on the grounds of the Iowa Lakeside Laboratory in Dickinson County, Iowa. Nests of the thatching ant were marked with metal tags on wire stakes and were plotted by compass readings from conspicuous features of the surroundings. The survey was repeated each summer; new nests were located and marked, and the loss of old nests recorded. The data are presented in table 1.
