A Generic Synopsis Ojf the Ceratopogonidae (Heleidae) of the Americas, a Bibliography, and a List of the North American Species

This paper deals with a group of insects which until recently has been considered a subfamily of the Chironomidae. The group is rather compact and this led Malloch (1915 a ) to propose the separation of it from the Chironomidae as a distinct family. A basic work on this family was published many years ago by Winnertz (1852), and since then a number of more or less comprehensive papers with synoptic tables have appeared, among them, those of Malloch (1915 a ), Goetghebuer (1920, 1933, 1934), Kieffer (1925 a , 1926), Edwards (1926), Johannsen (1931), and Macfie (1940 a ). The works by Kieffer and Macfie include the genera of the world. The fact that some of the members of the family are blood suckers has in recent years aroused renewed interest in them with the result that a number of entomologists in different parts of the world are now engaged in a study of the species.
