H. Ashmead to the United States Government, through the Entomological Department at Fig. 21. Fig. 22. Although Leucania unipunda (Fig. 21, the moth; Fig. 22, the caterpillar,) is a permanent resident in Ontario, and is frequently found quite abundant, it has never been reported as attracting special attention from its destructive effects on farm products here; and yet there does not appear to be any reason why it may not at some time do so. The army worm has caused great loss in the Maritime Provinces, whilst in New York State and Massachusetts, where the climatic conditions must very closely resemble our own, it has been at times particularly destructive, whole fields being utterly ruined by it. Mr. Scudder made a calculation from what he saw, that there must have been at least two million worms to the acre, destrojano- an entire field in ten or twelve days. Therefore Mr. Ashmead's vivid description of the tremendous power of a combined attack of these despised creatures, should arouse those interested to the terrible possibility that may be awaiting them, and to guard themselves as much as possible against it, for it is a well known fact that slovenly farming is a great source of encouragement to all kinds of pests. The army worm had a public reputation long before the moth, which gave rise to the destructive hordes, was certainly known to be the parent of all the mischief. It was about the year 1861 that the late Prof. Fitch unmistakably traced the connection between the two, and since then, by the careful industry of others
