By Alexander Dyer MacGillivray. This superfamily is differentiated from the other superfam-iHes of Hymenoptera by having the cephahc end of the ahdomenas broad where it is joined to the thorax as the caudal end of thethorax, never constricted into a narrow pedicel; by having thefirst abdominal segment joined to the abdomen, instead of beingclosely anchylosed to the thorax and bearing a pair of spiracles,and usually with its tergum longitudinally divided at middle; bythe retention in practically all the species of the base of theradial sector; and by the presence in many of the species ofmore than one anal cell. Their larvse either feed externally on the leaves of plants,within their stems, or within the trunks of trees. They can bedistinguished from the
