A Geometrid moth sent to me for determination by Dr. Fletcher some time ago, appears to belong to the well-known European species, Himera pennaria, Linn. This species has not previously been recorded as occurring on this continent, and there is always the suspicion of a mistake when a species belonging to the Old World fauna is reported in America for the first time; but this species is distinctly labelled as captured by Mr. L. Fanshawe at Tamarisk, Manitoba, and I see no reason to doubt the genuineness of the record.
