ingly small number of species. The Gelechiid, Gnorimoschema och- 

 reostrigeUa, was the only really common micro; some species of 

 Tortricids were found, and Crambids were fairly numerous. Butter- 

 flies were not uncommon; and representatives of several genera of 

 day-flying Noctuids were captured on flowers. The most striking 

 feature of the insect fauna at the higher altitudes at this time was 

 the presence of great numbers of Syrphus flies, representing many 

 species. Bumble-bees were common in the meadows here, with a 

 mimicking Syrphus fly. 



The microlepidopterous fauna of the region shows a mingling of 

 elements derived from several physiographic areas; as might be 

 expected from its situation at the eastern edge of the Rocky ^foun- 

 tains, with the plains to the east, and its connection with the Pacific 

 Coast and Sierra Nevada through the Columbia River Basin. Its 

 position in the Northern Rocky Mountain Region relates its flora 

 and fauna to that of the north and makes possible connections with 

 more easterly forms. Thus we have species here hitherto reported 

 from Texas, New Mexico and Arizona, from the more southern 

 Rocky Mountains, from the Sierra Nevada of CaUfornia. from 

 Oregon, and species whose range includes the whole northern United 

 States and Canada. The Lepidoptera of the Kootenai District 

 of British Columbia (Dyar, 1904) is on the other hand, most nearly 

 related to that of the Sierra Nevada. This region, although not far 

 from Glacier National Park, lies entirely on the Pacific side of thg 

 Continental Divide in the Columbia River drainage basin. 



All of the localities mentioned in the following pages may be 

 found on the U. S. Geological Survey topographic map of Glacier 

 National Park. The altitudes of the chief points at which collec- 

 tions were made are as follows : 



Glacier Park Station, 4796 feet. 



Two Medicine Lake, 5175 feet. 



St. .Mary, 4472 feet. 



Going-to-the-Sun Chalets, on St. Mary Lake, about 4600 feet. 



McDermott Lake, 4860 feet. 



Swiftcurrent Pass, 7176 feet. 



Granite Park, 6500 feet. 



In this paper only those species belonging to the families formerly 

 grouped together as Tineina are included. The Tortricid families of 

 which many species were collected are omitted here. In addition 

 to the species of Tineina recorded in this paper as occurring in 

 Glacier National Park, many others, chiefly Gelechiidae and Cole-
