The European corn borer, Pyrausta nubilalis Hubn., has been remarkably free from attack by parasites native to North America. Only two, Labrorychus prismaticus Nort. and Aplomya caesar (Aldrich), have occurred regularly in Canada. Of these Aplomya caesar has been by far the more abundant on the borer. Its presence on corn borer was first noted by Vinal and Caffrey (12) in 1919, at which time it was identified as Exorista nigripalpis Townsend.

In the course of my work on North American Eupithecias a number of species have gradually accumulated which I had, from time, to time, tentatively set aside as probably new but which I did not venture to describe as such until I had secured a better working knowledge of the species already named. Rightly or wrongly I believe I have now attained this desirable position and in consequence offer herewith h descriptions of certain new species together with genitalic figures of both sexes, as far as material is available.

It has always been presumed that the rabbit tick would not feed on man, and a careful search of the literature fails to show any record of it doing so. Therefore the following incident that occurred during February, 1945, is of interest.
