The descriptions are supplemented with illustrations of the morphological characters of taxonomic importance. Fig. 17 presents an anterior view of the head of Panorpa, showing the dis- tinctive elongate rostrum of most of the Mecoptera. Ocelli are present in all genera of the North American Mecop- tera except Merope. In Boreus the ocelli are indistinct, and numerous au- thors have reported them absent. In all genera the large, lateral compound eyes are widely separated, except those of Merope, which are reniform and al- most contiguous dorsally. The shape and venation of the wings vary from genus to genus. Fig. 24, 50, 64, and 80 illustrate the wings of all midwestern genera. In Apterobittacus the wings are absent, and in certain.
