III; This superfamily includes moths of medium or small size ; but so large a proportion of the species are small that the superfamily is commonly classed with the two following as Microlepidoptera. The members c. the different families included in this superfamily difler so greatly in appearance that it is not possible to give a gen- eral description that will serve to distinguish it. It is necessary to study structural char- acters to find evidences of a common bond, and here as in other groups we find the structure of the wings most useful for this purpose. Tx ^^^ As a rule there are Fig. 270.—Wmg^ oi Nomopkiia noctueiia, three anal veins in the hind wings and two in the fore wings. In this respect this superfamily agrees with the preceding families and with the two following superfamiUes. But in most cases the Pyralids can be recognized by the fact that the subcosta and radius of the hind wings are separate along the discal cell, but grown.
