Some few weeks ago I had an inquiry referred to me by the Editor of the American Miller from a Canadian correspondent, who stated that the flour moth was less than fourteen miles away from his mill, in Wellington (Ontario) district. I contributed a short article regarding this moth in the May number of the American Miller, in response to which two other localities have been discovered. One comes from York district, along the Lake, and one from Leeds district, along the St. Lawrence River. It seems clear to me that this insect is spreading along the watercourses of the lakes and inland along the railroads. Four other cases were reported to me, with larvæ and pupæ from each, from the United States side, one coming from Ohio, the first reported from that State, and three from New York.
