In order to make, it is trusted, the tables of more service, those of other families have been added, either as compiled or reproduced from standard authorities, or pre pared from the examination of specimens in the author's collection. It will be understood, however, that, in not a few families, the pres ent condition of American dipterology does not admit of the prepa ration of synopses free from error; the writer's acquaintance, too, with not a few families, has been less complete than with others, and it is very true that only he who has made a critical study of abundant material is competent to compile such tables with much success. For this reason, the tables of genera in the Nematocerous and Muscid families have been omitted. It may be mentioned that very nearly all the genera defined in the present work have been examined by the writer, though not all with the same degree, of critical study. The faunal limits embraced are those north of Mexico; and whenever extralimital forms are introduced they will be found preceded by a 0.
