ASSINIBOIA. MICRO-LEPIDOPTERA, COLLECTED BY MR. T. N. WILLING
Published online by Cambridge University Press: 31 May 2012
Extract
Tortrix conflictana, Walk.— Five specimens: Lethbridge, Macleod and Pine Creek; VII., 8, to VII., 13. Larger and the bands more suffused than Eastern specimens.
Tortrix argentana, Clerck.— Three specimens; Macleod and Lethbridge; VIII., 8 to 15. I have a long series of this species from Western America, south nearly to Mexico, and north to British Columbia, likewise a series from Europe, and every time I examine them I am impressed with the feeling that our American species differs from the European, but further study is required before deciding either way, in the meantime the European name can stand.
