Insects; Insects; Myriapoda; Arachnida; Crustacea. 3l6 TRANSFORMATIONS OF INSECTS, to certain species, and some of them resemble tattooings when they are done on hard wood, and really look like works of art. The large elms are destroyed by this beetle in particular, and a smaller one does a great amount of mischief to oaks. In the centre of the engraving on page 315 the long gallery made in the first instance by the female is seen to be surrounded by the radiating alleys, which have been gnawed out by the larvae. At the end of some of them nymphs may be observed, and in others larvae may be noticed. On the right hand side there are two perforations from without, and a female beetle may be seen at the end of each making its gallery. They have already laid some eggs which resemble white points within little niches on the sides of the gallery. These little niches will be enlarged. Tomiciis typographies. Scolytus desii'uctor. The beetles of these destructive species ai-e represented in their natural size, and magnified. in a radiating direction by the larvae, which, as they grow larger and larger, make wider and longer alleys. A closely allied genus has a species which does much mischief to fir trees, marking them just as if plans or maps had been cut upon them. It is called Tomicus typographus. The most numerous family of the order of the Coleoptera is that of the CurculionidcB, and many species are known as Weevils and Hog Beetles. The larvae of the Curctdioiiidce are almost always thick, massive, and slightly curled, like the larvae of the Scarabceidce; they are colourless, white or yellow, and they have flexible skins. These insects live hidden up in the trunks of trees, and in twigs or in grains. They have no legs, or they only possess the rudiments of them, in the form of small tubercles, which may be distinguished.
