=Calosoma scrutator=, is well named the handsome, for it is one of our most beautiful insects of this class. This, and the red-spotted _C. calidum_, may be seen upon trees, seeking caterpillars, upon which they feed. One of our most intelligent horticulturists has so high an appreciation of these insects, that he will not allow them to be disturbed, and whenever he sees any caterpillars in his orchard, he takes these beetles to the tree, and gives himself no further concern, knowing that the Calosoma will soon destroy every worm. =Coccinelidæ=, or Lady-birds, are most valuable aids to the cultivator, who is constantly liable to have his crops destroyed by the various species of Aphides. These little hemispherical beetles are familiar to every one, and known to the children as Lady-birds; but all may not know their value, nor be so well acquainted with the larvæ of these insects, which are the chief agents in the destruction of our troublesome plant-lice. Most persons would be very apt to crush these curious, diminutive, lizard-looking creatures, even at the time they were attacking the Aphides, instead of leaving them to carry on the warfare more effectually without our aid. These little friends have had a superstitious regard shown to them in many countries, which indicates that a glimmering idea prevailed respecting their usefulness. The Germans call them the _Marienkaefer_, or Lady-beetles, of the Virgin Mary. The French call them _Vaches de Dieu_, the Lord's cows, and our own children are all familiar with the nursery rhyme about the Lady-birds. These insects find their way to trees or plants that are infested with their proper food, the Aphides. These beetles hide under the leaves that cluster in sheltered nooks about or between the large roots of forest trees, where they can be found on any mild winter day, and may be carried to the green-house or to the window plants that are infested with plant-lice. They will not only devour these pests, but will soon lay eggs that hatch and produce the larvæ which are so voracious as to clear the plants in a short-time. A little attention to the habits of these insects may spare us great losses from the plant-lice. =ORTHOPTERA.=--GRASSHOPPERS.
