Now that the winter is well advanced and before many weeks are over spring will be upon us, it reminds me of many enquiries made during the last few years about the localities and dates of diurnals captured by me in the North-west in 1883 and 1884. These particulars are nearly all to be found at the National Museum of the Gelogical Museum at Ottawa, but for the benefit of those who may be visiting the North-west with a view to collecting diurnals, I propose to gie such information about the rarest species as my notes supply, and as my limited time will permit.
