In August last, when visiting Mr. E. Firmstone Heath, of The Hermitage, near Cartwright, Man., I had an opportunity of examining his fine local collection of Lepidoptera, which consists of twelve cases of well-set and preserved butterflies and moths. Among the butterflies were some species, the occurrence of which in Southern Manitoba surprised me very much.

Mr. Heath's residence is situated in a beautiful wooded valley, and on the bank of a small winding river, the Indian name of which means the “Long River which runs crookedly.” The trees on the banks of the valley, which is about a mile wide at The Hermitage, are chiefly scrub oaks (Quercus macrocarpa), ash-leaved maples, aspen and balsam poplar (white and black poplar of the settlers), Saskatoon (Amelanchier alnifolia), white thorn (Cratœgus coccinea), wild plum, a few American elms, choke-cherry, and various willows. The locality is undoubtedly a rich one, presenting a great variety of natural habitat for insects. The general character of the country surrounding the valley is a rolling grassy prairie, here and there broken by farms, and bluffs of white poplar.
