THE TENTHREDITES. 175 The females lay their eggs by inserting them with their saw-ovipositor between the skin or cuticle of the turnip leaf and itscellular or parenchymatous structure. The q^^ is therefore onlyseparated from the atmosphere by a most delicate membrane,so that the heat and moisture soon affect it and hatch the littleAtJialia ccntifoliiu very rapidly. It appears necessary that this&^^ should be exposed to much heat in order to hasten the birthin time for the turnip to be enjoyed by the larva. Newportstates that the cocoon of this insect is lined with silk. The larvae of the genus Sclandria are of a somewhat peculiarshape. Their legs are extremely short, and their bodies are lubri-cated with a viscid secretion which makes them look like smallslugs. Reaumur, in fact, called them slug larvae. The larvae ofSelandria Aithiops often become very injurious to cherry, Lopliyrits pnti. and other fruit trees. They remain perfectly quiet during theheat of the day, and seem to draw their heads within the firstsegment of their bodies, and they are then covered over withthe slimy moisture so as not to look like insects at all. Bynight and during the early morning they are lively enough,and they then devour the foliage. The Lyditcs form a small group of saw-flies ^\hich are charac-terised by having a great number of joints to their antenna;. Theyare the saw-flies of the north, and they attack fir trees and pines. The Lflphyii, which belong to this group, have a thick body,and the males have doubly pectinated and feathe
