 tremuloides}, willow, birch (Bctula papyrifera} , alder (Al-

 bleberry (Rubtts nutkanus), raspberry (Rubus strzgosus}, 

 gooseberry (Ribcs irriguum}, service-berry \Amelanchier 

 Jloridd) and huckleberry ( Vaccinitim membranaceum} are com 

 mon shrubs, while among the most abundant flowering plants 

 are Epilobium spicatum, Spircea corymbosa, a species of 

 Hieraceum and Anaphalis margaritacea. Between the upper 

 portion of the thickly timbered area and the rocky peaks of the 

 mountain summits there is usually a considerable area with scant 

 and stunted trees, or no trees at all, the ground covered with 

 sedge, heather (Phyllodoce empetriformis and Cassiope mer- 

 tensiana) and a variety of boreal or subarctic flowering plants. 



Following is a list of the localities where collections were 

 made. Whenever possible the exact or approximate altitude is 

 given. 



Kaslo (altitude 1,670 feet), May 29 to August 20. As 

 stated above, this town, located on Kootenay Lake, was our 

 headquarters, and the great majority of our specimens were ob 

 tained within easy walking or rowing distance of there. The 

 town is built upon the south side of a small bay and is bounded 

 on the south by Kaslo Creek at the time of our arrival a large 

 and powerful mountain torrent though diminishing greatly in 

 volume later in the season. At no place did collecting give bet 

 ter results than here. The creek harbored a variety of neurop- 

 teroid and other aquatic Iarva3, while the deciduous trees which 

 lined its banks were the resting places of many stoneflies, cad- 

 disflies and the like. From the many young trees springing up 

 in the clearings back of the town and in those places which had, 

 a few years back, been visited by forest fires, a variety of wood- 

 inhabiting Coleoptera were beaten, together with parasitic Hy- 

 menoptera, Chrysopidas, Hemerobiidae and Raphidiidae, small 

 Diptera, Homoptera and Heteroptera, and innumerable spiders. 

 The thimbleberry and other bushes made excellent sweeping for 

 small Hymenoptera ; the clover patches, on sunny days, were 

 alive with various kinds of bees ; and the grass and weeds of 

 pastures and vacant lots'yielded an embarrassing number of vari 

 ous small Diptera. Butterflies and moths of many kinds were 

 abundant, especially in the clearings and more open forest and 

 along the roadsides, while many of the night-flying moths 

 could be detected and put to flight by thrashing the underbrush, 

 shrubs and young trees with a stout stick or pole. Caddisworms, 

 mosquito larvag, aquatic Coleoptera and Hemiptera, etc., were 



*The balm of Gilead poplar is called " cottonwood " in the Northwest.
