In the perfect state (imago) Diptera are to be found practically everywhere and in every conceivable situation, a few species occurring even in very high latitudes and desert areas. A general introduction to the whole order of the Diptera is not contemplated in this volume, and the various parts of the insect are sufficiently well known to the majority of entomologists not to require more than a brief description. Tlie following ex- planatory paragraphs on the external anatomy of a fly are there- fore curtailed as far as expedient. The genus Tijmla is selected as an example owang to its being the chief genus ol the TiPULiJ)iE, the dominant family included in the present work. ^. -Diagram oi'a Tipulu, to illustrate tlic parts of a Dipteroii.
