almost incredible. Of these are the Tomicus typographus and the Hylurgus piniperda. The 
former receives its name of the Typographic Beetle, from the circumstance that the burrows 
formed by it ia feeding upon the soft wood, immediately within the bark, often present a rude 
resemblance to printed characters. The devastations of these apparently contemptible foes are 
sometimes so formidable in the pine-forests of Germany, that prayers for their restriction are 
offered up in the churches; we are told that in the year 1*783 at least a million and a half 
of trees were destroyed by these insects in the Hartz forest alone. The Tomicus pini infests the 
white-pine of this country, and the T. liviinaris is suspected of producing the yellows in peach- 
trees. Both of these insects are exceedingly minute, being about one-sixth of an inch long. 
THE LONGICORNIA. 
The insects of this tribe, called Capricorn Beetles, and distributed throughout most parts of 
the world, are generally distinguished by the great length of their 
antennae, these being usually considerably longer than the body. 
Most of these are large and elegant, often adorned with splendid 
colors, or armed with spines upon the thorax and other parts of the 
body, which sometimes render their appearance curious and even 
grotesque. The Ceravihyx Alpinus, of Linnaeus, common in the Alps 
and in France, where it is called Rosalie, is of an ashy-blue color, 
and is a very elegant species. One of the handsomest British beetles 
is the Callichroma moschaia, belonging to this tribe. It is also dis- 
tinguished by its peculiar musky odor. It is of a fine metallic-green 
color ; but many exotic insects nearly allied to this, are far more splendid in appearance. 
The larvaa of some of these insects live in timber, often doing enormous injury to trees 
by eating large passages 
through the solid wood. 
They are soft, fleshy grubs, 
generally widened in front, 
and almost destitute of 
feet. They appear to live 
in this condition for sev- 
eral years, and afterward 
probably pass a consider- 
able time in the pupa 
state, as the perfect insects 
have been known to eat 
their way out of timber which had been for some time worked up into furniture. They have 
been carried from one country to another in timber, and have thus become widely dispersed. 
These beetles generally produce a sharp, grating sound, by the friction of the back of the pro- 
thorax upon the base of the scutellum. 
There are several noted species analogous to the preceding. Among them is the Leptura 
mordax of Europe, three-fourths of an inch long, 
which bites severely when captured with the hand. 
The Clytus campestris, of this country, is injurious 
to fallen chestnut timber, damaging it for rails. 
The larva of the Saperda Candida, called Apple-tree 
Borer, penetrates the young apple-trees just above 
or below the surface, then cutting its way in a 
winding manner upward, thus often proving de- 
structive. The S. tripunctafa, called the Hasp- 
berry Saperda, does mischief to the raspberry and 
blackberry bushes, by laying its eggs in their stems ;

the grubs burrow in the pith, and destroy them.
