This species is fully discussed on page 185; it is constantly being introduced north of the regions in which it has become established, but is evidently much more decidedly affected by cold than P. americana, and in consequence has never become permanently established in the United States north of the areas in which the winter climate is comparatively mild. In the colder regions of the United States, when it has appeared in greenhouses and such artificially heated places, it has been found to breed and increase in numbers with great rapidity, temporarily becoming a dangerous pest, so that vigorous efforts have been found necessary to exterminate such a colony. ^^^
North of Pennsylvania, occasional adventive specimens of the species are constantly being reported; such records are found from Montreal, Quebec; Toronto, Ontario; Wellesley, Massachusetts; Wallingford and New Haven, Connecticut, and from Minnesota.
The following adventive material is now before us.
