The nervous system is similar to that of the Orthoptera, and consists of clearly distinct thoracic and abdominal ganglia. There is always a muscular gizzard on the digestive canal (Mynneleontidce, Panoi^nda^. A sucking stomach Is found only in the ffemerobidce. Six to eight long Mal- pighian tubes arise from the hindgut. The metamorphosis is always complete. The larvre prey on other animals, and are provided with biting or sucking forceps (formed from the mandibles and maxillae). They pass into a quiescent pupal stage, in which the parts of the winged insect can al- ready be made out. The pupa is often surrounded with a cocoon, but possesses the power of locomotion to a certain de- gree, since before the animal passes out of the pupal stage it ceases to be quiescent and seeks out a place suitable for a development. Fossil remains are found in tertiary forma- tions and in amber. Sub-order 1. Planipennia. Front and hind wings similar, never capable of being folded.
