Insects at Home: Being a Popular Account of British Insects, Their Structure, Habits, and Transformations
In spite of the difficulties which attend the examination of these insects, the entomologist will find his time well bestowed upon them. Independently of other soiuces of interest, these tiny Beetles are marvellously beautiful. Their colours are exceedingly various, and the richness and perfection of the sculpture which adorns their tiny bodies I! must be seen to be appreciated. It is as if the very exuberance of creative power had sported with these Httle creatures, a thousand of which could be contained in a lady’s thimble, and yet which bear upon every portion of their bodies a limitless profusion of highly-elaborated ornament. The head and thorax are covered with a multitude of deep impressions, at first seeming as if scattered at random, but in reaHty disposed with most conmmate art; while the elytra baffle all attempts to describe their varied beauty. Agreeing in one point^namely the bl ndges which run longitudinally along them-th^ are If

I have often thought, when examining these little beings with the microscope, that artists in metals might find in them
other Beetles an exhaustless mine of new and most beautiand
ful patterns ; and, indeed, artists, no matter in what department, cannot do better than study the insect tribes, in order to learn many secrets of form and colour. as they are,. the Apions often do much damage to the

The fact is that many names have no explanation. Systematic
entomologists, when they iind new genera crowding on them,
are quite at a loss for suitable names. They can manage I of the chief characters which marks the species, and give its
pretty well with the specific name, because they can take one j synonym in Gfreek or Latin. But this is not to be done with
the generic title, and so they are driven to various expedients
such as calling a new genus after the name of some particular
friend, or a favourite child, or perhaps a pet dog or cat.
Having exhausted their resources, there yet remains another,
which will account for some of the remarkable names which r we see in entomological lists. Cut up some paper into small squares, and write upon each of them a letter of the alphabet —a child’s toy alphabet will answer still better. Take at random half a dozen letters, taking care to have a vowel or two among them, arrange them on the table, and try if they can be made into a pronounceable word. If not, take some more letters and try again ; and when a word is at last formed, there is the generic name ready. If a sort of classical air be thought necessary, all that is required is to add us or um at the end of it.
I We now come to the Weevils with elbowed antenn®, the first family of which is the Brachyderidas. In these insects the head is short, wide, and set on the thorax without any separate neck, a peculiarity which has gained for the family the name of Brachyderidce, or ‘ short-necks.’
Our example of this family is Sitones lineatus, which is represented on Woodcut XVII. Fig. 4. This genus is known by the possession of wings, the short beak, and the third joint I the second. About of the antennae, which is shorter than ► tourteen British species of this genus are acknowledged. The present species is a pretty though not a brilliant insect. The ground colour is black, but the body is clothed above with sea es of a warm-brown hue, while the under smface of the i body IS similarly clothed, but with scales having a silvery us re. There is a central furrow on the disc of the thorax, and

Fourteen species of this genus are known, and all of them
make similar cocoons in which to pass their pupal existence.
These are not the only cocoon-making Weevils, for there is
another genus, Cionus, which is equally distinguished as an architect. The cocoon of the Cionus resembles in every essential that of the Phytonomus, hut is spherical instead of oval. These insects feed on the mullein ; and the best plan to secure the cocoon of the insect is to find out some place where mulleins grow, and search them diligently. The Grreat Mullein ( Verbascum thapsus), which grows in waste grounds, on sandy or gTavelly soil, is nearly sure to furnish either the Beetle or the cocoon, and perhaps both. Mr. Stephens states that he took all the species of this genus upon a single mullein plant. The Knotted-root Figwort (Scrophularia nodosa) is another of their favourite plants. The generic name, Phytonomus, is formed from two Grreek words, and signifies ‘ herb-grazer.’
