It would seem appropriate that this hitherto somewhat rare and inconspicuous little carabid should be brought to the notice of the Entomological Club of the A.A.A.S. in its new role of a benefactor.

I have been observing its habits for two years, and am confident that to it, more than to any other agent, do we, in the neighborhood of St.Louis, owe our present comparative freedom from the Web-worm nuisance. Whereas formerly almost every other tree would, at this season of the year, be infested with one or more of the disfiguring nests, they are now so few and far between that it requires some search to find one.
