Some galls are hard, like the one found on the Turkey oak, from which ink is made : while others are large and juicy, resembling cherries, or small apples, among which is the so-called apple of Sodom. Others, like the Bedeguar, which is found on roses, have a mossy appearance. The latter are produced by a small black saw-fly, with part of the legs, and, in the female, the base of the abdomen, red j" " beneath. Some of the smaller gall-flies do not pro- duce galls, but are parasitic on other insects; but galls are very liable to the parasitic attacks of other insects, especially to those of small brilliant metallic green four-winged flies, belong- ing to an allied famil)', with very few nervures, but with a black membranous spot on the front edge of the fore wings, and angulated antenna?. Many galls do not begin to grow until the lar\'a is hatched and begins to eat. We now come to fi\e or ; families of parasitic species, popularl}'called ICHNEUMON- FLIES, and immensely numerous and varied. There are probably considerably over 2,000 species in England alone ; but they are com- paratively little known or studied. Some of these ha\'e beautifully delicate wings, fringed with long bristles, and arc among the smallest insects known, being of quite microscopic dimensions. These are parasitic on the eggs of various insects, and some are aquatic. But the more typical ichneumon-flies arc of larger size, often measuring more than an inch across the wings. Their bodies are usually black or yellow, and there is often an irregularl}' shaped space in the middle of the fore wing, where the veins of the wing c
