These maggots were orange-red, of various depths of colour, and they varied also in form of the anchor process, and also in this process heing sometimes either not present or not observ- able. The Midges which were reared by Mr. Baillie were ex- amined for me by Mr. Meade, of Bradford, who stated the insect belonged to the Cecidomyia, sub- genus Diplosis, H. L. W., and he considered it was probably a new or undescribed species. The spe- cimens sent might possibly be small varieties of C. tritici, but as all that were sent were females the kind could not be determined with certainty. * Prevention and Remedies.—The best method for preven- tion of this "Bed Maggot" is to give it no winter shelter, which IS naturally at the roots of the Corn crops or of Couch (and possibly some other) grasses; artificially in large chafif- heaps. The chaff-heaps and the rubbish and dust from the threshing-machine can be easily managed ; and in the fields a great deal of the Bed Maggot may be got rid of by special methods of ploughing, or by taking the cultivator through the land, and collecting and burning the stubble-roots. In Canada, when this maggot was especially hurtful, it was considered a complete cure to turn down the surface of the field with the Michigan plough, which, with the first turn- furrow, takes off about two inches of the surface, together with the wee
