Felt (1940) mentioned a midge in Douglas-fir needles which he called Cecidomyia sp.; this reference was quoted by Barnes (1951). Denton (1954) reported that a midge, identified by the Division of Insect Identification, United States Bureau of Entomology and Plant Quarantine as Cecidomyia sp., occurred in needles of Douglas fir in northeastern Washington, northern Idaho, and northeastern Montana. In 1954 the author reared some adults which H. F. Barnes (in litt. 1957) referred to the genus Contarinia Rond. Unpublished records from 1935 to date indicate unidentified needle-inhabiting gall midges throughout most of the host range. Recently the author found indications of a species comples which were confirmed by further rearings of adults. This paper presents the description of three new species of Contarinia Rond., reared under similar conditions, from material obtained at Oyama, B.C.
