 A HISTORY OF NORFOLK is found it does not seem to matter how often it is visited, as something fresh is almost sure to be taken. There is a peculiar habit found in the larva of Limneria kreichbaumeri when in the cocoon ; it has the power of leaping a considerable distance into the air. The cocoon is semitransparent, and when held up to the light the larva may be seen to bend itself into the shape of a U ; then press its head and tail against one side of the cocoon, and suddenly release them so that they strike the opposite side, hitting it a sharp blow which causes it to make a leap. When held in the fingers the tap may distinctly be felt and heard. TENTHREDINIDiE Tenthreda livida, Linn. Norwich ; com- mon, June and July — colon, Klug.
