Entry No. 42 - Material from the Lillooet area similar to fig. 3 in Plate No. 10 The Butterflies of Canada.
Entry No. 64 - The Northern Blue (Lycaeides idas) is now incorrect for the Lillooet area because the larval host plants are Lupines not Blueberries. It is called Anna’s Blue (Lycaeides anna) which is a new species.
Entry No. 82 - The Mount Rainier and Purple Fritillary may be two distinct species. Material from the polar regions is the Arctic Fritillary which is distinct from the Rainier and Purple Fritillaries.
Entry No. 88 - The Variable and Anicia Checkerspots are two distinct species.
Entry No.102 - Extinct in the Lillooet area including southern British Columbia
Entry No.112 - Two species could be involved in this complex which are Oeneis chryxus and Oeneis calais altacordillera a high elevation alpine form.
