Order Neuroptera. The Neuroptera are characterized by the abundant and rich venation of their wings, in which numerous cross-veins extend between the longitudinal ones. The mouth-parts are adapted for biting, the mandibles being in some forms (Cory- dalis) very large. The lace-winged flies {Chrysopa) also be- long to this group, as does also the Ant-lion (Myrmdeon, Fig. 240), whose larva excavates a funnel in loose sand, and buries itself at the bottom with only the head and powerful. Fig. 340.—Myrmeleon obsoleius (from Packard). mandibles projecting, ready to snap up any insect which slips down the yielding sides of the trap. The larvae are usually Thysanuriform, those of Chrysopa attacking Aphides, whence they are frequently termed Aphis-lions, while those of Cory- dalis are aquatic and possess tracheal branchiae upon the abdomen. This larva is familiar to anglers as the Hell- gramite. The metamorphosis is complete. 11. Order Panorpata. This order contains a small number of forms, the majority of which possess membranous wings resembling those of the Neuroptera, except that the cross-veins are not so numerous. The anterior part of the head is produced into a downwardly projecting snout, at the extremity of which are the small biting mouth-parts, the arrangement recalling that found in the Curculionidse among the Coleoptera. In the genus Fa-.
