the tree, eats a hole through the shell with its strong jaws, and pushes itselfthrough the aperture thus made; although it appears too small to admitthe body, which contracts itself to get through, and then falls to the ground,having no legs to support itself on the husk. Legs, however, would be anincumbrance to the insect, as it is born in the midst of its food ; and whenthis is consumed its feeding time has terminated, and it is ready to make itsway into the earth; where it forms an oval cell, and changes into a pupa;soon after which the perfect insectmakes its appearance. In fig. 1947.,a shows the wound made by theintroduction of the egg into theyoung fruit; b, the hole in themature fruit, by which the larvahas made its exit; c is the larva;d, the pupa; and e, the perfect in-sect (these last three figures beingrepresented about one third largerthan the natural size). The tip ofthe rostrum, magnified, is shown atf; g being the jaws, and h a sideview of a single jaw. In additionto this insect, Orchestes avellanae(one of the small flea weevils),

Strophosomus coryli, Apoderuscoryli, AttGabus eurculionides,

Amongst the Linnasan Hemiptera are : Cimex coryli, avellanae,and annulatus Linn-, Cicada aurita, bicordata, and coryli; A'phis coryli; andCoccus coryli. Hemerobius hirtus, amongst neuropterous insects; andAllantus coryli, amongst the saw-flies, complete the list of the chief speciesof insects which feed upon the common nut.
