“…After a careful examination of the literature, I have come to the conclusion that the midges collected by Professor Newstead belong to an undescribed species, and I, therefore, name and describe it as Lutz (1914). t This specific name is preoccupied by F. crudelis (Karsch), but I refrain from proposing a substitute because the descriptions appear to indicate that the species is almost certainly identical with F. tropica, described by Kieffer (1917) from Costa Rica.…”
