 | | It is customary to divide the Orthorrhapha into the two divisions Nematocera and Brachycera, in the former of which the antennae are elongate and in a more or less primitive condition, as described above, while in the latter these organs are short, and, as already explained, apparently composed of only three joints. |
 | | Within the divisions namedOrthorrhapha Nematocera, Orthorrhapha Brachycera and Cyclorrhaphathe constituent families are usually grouped into a series of superfamilies, distinguished by features of structure or habit. |
 | | Certain extremely aberrant Diptera, which, in consequence of the adoption of a parasitic mode of life, have undergone great structural modification, are further remarkable for their pecu]iar mode of reproduction, on account of which the families composing the group are often termed Pupipara. |
