Abstract
THE confused flour beetle, Tribolium confusum J. du V., and the rust-red flour beetle, T. castaneum Herbst, are the most abundant and destructive beetles infesting flour and other prepared cereal products. T. confusum is also one of the insects most commonly bred in the laboratory for experimental purposes. Hitherto it has been maintained1,2,3 that there are no secondary sexual characters in the adult stage, and in consequence the beetles could only be sexed in the pupal stage, a procedure which is frequently very inconvenient.
