The plercryate, replete, or rotund, is a worker, which inits callow stage has acquired the peculiar habit of distending the gasterwith stored liquid food (honey) till it becomes a large sphericalsac and locomotion is rendered difficult or even impossible (Figs. 218and 219). This occurs in the honey ants (some North American speciesof Myrmccocystus, some Australian Melophorits and Camponotus, andto a less striking extent in certain species of Prenolepis and Plagiolepis}. 23.
