The Cuckoo-flies, The cuckoo-flies are wonderfully beautiful creatures, be- ing usually a brilliant metallic green in color. The species are of moderate size, the largest being only about a half inch in length. They can be distinguished from other Hymenoptera by the form of the ab- domen, in which there are only three or four visible segments (Fig. 763), except in the male of a single genus {Cleptes), where there are five.
