* Tbe ancient belief thai bees were generated in decaying carcases of cattle, etc. (c.f., Judges xiv., 13 — 18, and Virgil's 

 Fuurth Oeorgic). The factA are. that the fly F.ristatis tenax resembles the honey-bee, and that its larvie are carrion-eattrs ; 

 hence when they have finished a caicase they pupate tjeneath the slctii and dibris that remain, emerging eventually as perfect 

 insects in crowds which were mistaken for swarms of liees.
