* The ancient belief that bees were generated in decaying carcases of cattle, etc. (c.t., Judges xiv., 12—18, and Virgil's 
Fourth Georgic). The facts are, that the fly Eris¢a/is tenax resembles the honey-bee, and that its larva are carrion-eaters ; 
hence when they have finished a carcase they pupate beneath the skin and dééris that remain, emerging eventually as perfect 
insects in crowds which were mistaken for swarms of bees.
