But little attention seems to have been given to Micro-Lepidoptera by Canadian collectors hitherto, so far as can be gathered from the printed lists, 83 names being all that could be reached when the latest one was published. It is certainly not for want of an abundance of material to work upon. I turned my attention to them specially last summer, and was quite surprised to find that so many different species could be obtained when sought for, considering that the season was a most unfavorable one for collecting generally, and no doubt affected them similarly.
