The Comstock–Needham system is a naming system for insect wing veins, devised by John Comstock and George Needham in 1898. It was an important step in showing the homology of all insect wings. This system was based on Needham's "pretracheation theory" that was later discredited by Frederic Charles Fraser in 1938.
John Comstock was friends with Fredric Charles Fraser.
John Comstock had a stroke in 1926 and lived for 4.5 more years until his death in 1931. Fredric Charles Fraser didn't discredit the Comstock-Needham theory until 1938. 7 years after Comstock's death. Comstock was an American, Fraser an Englishman, so the odds are slim that given it was the 1930's that they even met.
