This last I have never been able to rear, but have seen it on several occasions in the bot-stage. Boot-eating Flies (Anthomyidse). The Anthomyidse include a great number of flies which are all more or less dull in colour, and covered with many bristles and hairs. Their larvae are white footless grubs, which taper to a point towards the head end, and are blunt at the posterior end. Several are very injurious to crops. No full description of the adults will be given here, as they are all much alike: only specialists are able to identify them with any certainty. The larvse live in the roots of plants and set up decay. The most important are the following: the Onion Fly {Phorhia eepetoi-um); the Cabbage-root Flies {Anfhomyia radioMi, A. brassicce, and A. floralis); and the Wheat-bulb Fly [Hylemyia coardata)..
