Family MEROPID. The members of this family are among the most ornamental of the Insessorial birds, and are as elegant in form as they are beautiful in colour. Europe, Asia, Africa, and Australia are the countries in which one or other of the not very numerous species are found. As the thinness of their plumage and the slightness of their form would indicate, they appear to be sensitive to cold ; and most of them are resident in the tropical or warmer portions of the countries mentioned, though one species, the A/erops apiaster, is very common in Spain. Insects of the various orders constitute their chief food. The species have been divided into several genera, Genus Merops. The species inhabiting Europe is the type of this form. 506.
