If they are terrestrial they probablybelong to the Order Coleoptera, the only Neuropterous larvsewhich are terrestrial being those of the Lace-winged Flies(Fig. 47), and of the Ant Lions. These larvae differ from theColeopterous larvse by their long and prominent jaws, whichproject horizontally in front of the head. Fig. 170. Fig. Fig. 172. Fig. 171.
