BULLETIN UNIVERSITY OF MONTANA. 



Montana, from Nova Scotia to Alaska, and southward along the ridges 

 of the Alleghanies into Virginia and the mountains of North Carolina. 

 It has been taken rather abundantly at Crow Creek, Flathead Indian 

 Reservation; at Missoula; at Rimini, 5,500 feet, near Helena, by 

 Brandegee. Taken by Barnes at Aldridge. 



One day in July, while camped at Crow Creek along the main wagon 

 road between Selish and Poison Brenthis myrina was found abundantly 

 in the grassy creek bottoms. Almost invariably they were taken on the 

 large blue Erigeron macranthus, common in the western part of the 

 state. The afternoon was warm, and was spent almost entirely in butter- 

 fly collecting. Nearly all the specimens taken were of this species.

August 8, 1904, an afternoon was spent at the upper end of Swan 

 Lake after insects. Brenthis myrina was the only common species, rest- 

 ing occasionally on the blue Erigeron or white Achillea. Several dozen 

 were secured, the return to camp revealing two deer in the marsh. 



One morning during the last week in August, 1903, as I was wading 

 through the tall wet grass, at the upper end of Swan Lake, just after sun- 

 rise, a butterfly was rather abundant above the tops of the grass. The 

 dew was wet and heavy, and no net was at hand. Batting down an insect 

 with my old hat it proved to be of this species. It may be called common 

 west of the range.
