Perhaps the following short account of a few days' spring collecting here may be of interest to readers of the Canadian Entomologist.

The locality I have worked from during the two years that I have been in the country, is close to the mouth of Fish Creek, about twelve miles south of Calgary, and a mile from the right bank (south) of Bow River. I have a fellow worker about nine miles further west, near the head of Pine Creek, by name Mr. Arthur Hudson, a keen observer, and, I believe, the only entomologist besides myself who has ever collected here for a whole season, and between us we are at present almost daily increasing the list of macro-lepidoptera found around Calgary. We have already over fifty species of butterflies on the list, with three or four more doubtful species, and are confident that we shall be able to make several additions during the coming season. Of the moths, more particularly the Noctuidæ (and their name here is certainly Legion!), new comers never cease, as I think Prof. Smith can testify. When Mr. Elwes paid me a visit in July, 1893, he asked: “Treacle is not much used here, is it?” I replied that I had only been “at it” for a month, and was fairly well pleased with the result, though of course my take might have been exceptional. Were I asked the same question now, I should, without hesitation, reply: “Well, just isn't it, that's all, and from June to October, too!” During last July I not unfrequently counted from sixty to eighty moths on a treacle patch about eighteen inches long and three or four wide, comprising about fifteen or sixteen species. A sight such as that, however, certainly is exceptional. However, I have other modes of collecting to speak of now, as at this early date treacle is scarcely worth working.
