page 1 54, and which has a very powerful and disagreeable scent. I In some parts of the country this liquid is considered to be a I g. toothache, the finger being first rubbed against the

legs of the Lady-bird, and then on the offending tooth. In its ; I larval state it emits a similar liquid from the tubercles upon

its body. ^ It is rather remarkable that the popular names of Lady-bird and Lady-cow are not peculiar to England. In France, for example, the insect is called Bete de la Vierge, or Vache a Lieu. The children, however, do not respect the insect in consequence of its popular names, but, on the contrary, when they catch one, look upon it as a means of showing their ingenuity ^ in prolonging torture without destroying life.

1 The next family, that of the Endomychidae, is represented

y one species, Lycoperdina bovistce, which is shown on Woodcut XXIV. Fig. 2. \ In this family the antennae are tolerably long, the thorax is impressed behind, and the last joint of the maxillary palpus is never hatchet-shaped. In the genus Lycoperdina the thorax is heart-shaped, and abruptly cut off at the base, and there is no distinct club to the antennae. The present species is an odd, black, flat insect, which has been very happily compared to a puff-ball (Lycoperdmi bovMtce), from which it derives its geoenc name, and makes its exit by the aperture which exists at the top of the fungus, and through which the spores escape like umber of puff-balls may be examined without a single sneci

The wide and deeply fringed maxilla is worthy of notice. This is the only English species of the genus, the second supposed species being nothing more than a variety.

The family of the Trichopteridse contains a good many of which we select one as our example. This is T/'ispecies, cho'pteryx atomaria, which is represented on Woodcut XXIV. Fig. 3.

These are all little Beetles, and, indeed, are the tiniest of the British Coleoptera. Small as they are, they can he easily when examined by the aid of a lens, so bold are recognised which mark them. The antennae are long, the characteristics and beset with long hairs, and having a bold threeslender, club. The wings are very long and narrow, and fringed jointed which has gained for them the name with hairs, a peculiarity or ‘ hairy wings.’ Sometimes the wings are of Trichopteryx, but when they are present they are always fringed undeveloped, are other characteristics of the family, but with hair. There for the recognition of any insect that belongs these are sufficient to it. the antennae are about

Passing by one family of this section, we come to the Pselaphidas, of which remarkable family two examples will be given, each illustrating one of the sub-families. 4

In these Beetles the elytra are very short, so short, indeed, that for many years these insects were classed among the Brachelytra. The club of the antennjB is bold and well-defined, the last joint being very large. The head is into a distinct neck. narrowed behind

The first sub-family is called the Pselaphime, and in them the antennae have eleven joints, and the eyes and parts of the mouth are well developed. The genus Pselaphus, of which there are only two British species, has the antenme, palpi and egs very long. The commonest species, Pselaphus HeiseL which IS represented on Woodcut XXIV. Fig. 4, is shining yellow-brown, has its body very flat and wide, and on each side 0 the suture of the elytra there is a stria which runs from the base to the tip. It can be shaken out of moss, as can its congener, PseZopAus Dresdenensis, which may be distinguished " ^ semicircular impression at the base of thelLrax B-’oUes is, perhaps, the strangest of all our uative ruseots, and how it can find any gratification m existence is not easy to see.

CHAPTER I.

These insects, popularly known as Earwigs, are remarkable for many reasons. None of them are large, and some are very small. There are but few species, and most of the British species are very common — in fact, much too common as far as flowergardens are concerned. Yet, though they are small, few, and common, they have been the occasion of more disputes among entomologists than all the other insects put together. Some asserted that they were an ‘ aberrant ’ branch of the Brachelytra and allied to the common Eove Beetles, while others as strenuously asserted that they belonged by right to the Orthoptera and were allied, though distantly, to the Cockroach. The use to which they put the forceps with which their tails are armed furnished another fertile source of dispute, while even their popular English name was cause for abundant quarrel one party considering the name to be properly Earm^, in allusion to the popular idea that they were in the habit of crawling into h^an ears ; and the other spelling the word Ear^omg, because the pread wing of the insect is succession, shaped like a human ear. and begin with the to occupy in the world first-namely, of insects. the position which they oimht

It is satisfactorily ascertained that they cannot be Beetles, if only for the one fact, that in the pupal state they are not inactive, but resemble in every respect the perfect insect, that the wings are except rudimentary. The elytra, instead of beinoorny, are soft and leathery, very small, without veins • and neaily, but not quite, cover the wings, the leathery hin’o-e of which projects just beyond them when folded.
