Most of the localities at which collections were made are somewhat 

 obscure, and not all are indicated upon modern maps. With one 

 exception they are trading posts of the Hudson's Bay Compan3\ It 

 may be well to mention the more important localities, with latitude 

 and other data, in the followino- introductory list: 



J^o?'t McMurray^ Athahaskd. — At the confluence of the Clearwater 

 and Athal)aska riycrs. Collections were made along the Athabaska 

 Riyer, near this post, earh^ in August, 1903. 



Fort Chipeivyan^ Athahasla. — On the north shore of Athabaska 

 Lake near its outlet. The eastern portion of the lake was still ice- 

 bound when I reached Chipewj'an on June 1, 11)03, ])ut the western 

 part had been nayigable for some days. Vegetation was not far 

 adyanced at that time, but seyeral ])alm3' days in succession brought 

 out man}' butterflies, and a number of species were collected. Fort 

 Chipew3^an is a good spot for collecting, there being manj' open, moss}^ 

 slopes with a southern exposure on the Archjean hills about the post. 



SuiitJi Portage^ AtJtaljasl'a {latitude GO). — A 1(J -mile portage around 

 the Smith Rapids, connecting Smith Landing, Athabaska, and Fort 

 Smith, Mackenzie. Butterflies Ayere numerous in the muskegs" and 

 about the water holes along the portage trail, June 11 to 13, 1903. 



Fort Resolution^ Mackenzie. — On the south shore of Great Slaye 

 Lake near the delta of Slaye Riyer. Fair collecting was obtained on 

 the open ground between the post and the lake shore late in June. 



Hay River., Mackenzie. — At the debouchure of Hay Riyer on the 

 southwest shore of Great Slave Lake. The last three days of June 

 were spent here, but owing to the inclemency of the weather yery little 

 collecting was done. A few species were taken in a swampy tract 

 adjoining the lake. 



Fort RaCf Mackenzie. — On the northern arm of Great Slaye Lake. 

 A few species were collected by Mr. Preble in August, 1903. Hud- 

 sonian faunal conditions. 



Fort Providence., Mackenzie. — On the north l)ank of the Mackenzie 

 Riyer, a short distance west of Great Slaye Lake. Butterflies were 

 numerous early in July. Many species were taken in the open pasture 

 back of the post, chiefly at the flowers of the silyerberry {Flieagnus 

 argentea)., and a species of gooseberry {Rihes oxy cant ho ides). 



Fort ISinipson., Mackenzie {latitude 61'-^ 52'). — At the confluence of 

 the Liard and Mackenzie riyers. Mr. Preble collected here in May, 

 1904, and several collections have been made in the past. One of the 

 best localities in the North for the lepidopterist. 



Mouth North Nahanni River, Mackenzie. — West bank of Mackenzie 

 River, 75 miles below Fort Simpson. The Mackenzie is here sharply 



"Throughout British America the term "muskeg" is applied to a peculiar type of 

 swamp or bog in which moss has accumulated to a considera])le di^pth. It usually 

 supports a scanty growth of tamarack or spruce.
