In that portion of the county which I have been able to explore I have not yet noticed the large ants Formica rufa and F. fuliginosa, with which so large a 'number of our myrme- cophilous species occur, and conse- quently the number of such species included in this list is very small Myrmedonia funesta, Grav.
