. The popular natural history . Zoology. 5S4 WOOD LEOPARD MOTH. a convenient cell in the tree, lining it with a fabric of mixed wood-scrapings and silken threads. Before it emerges from this retreat, it pushes itself thrcugh its burrow like a sweep ascending a chimney, protrudes about half of the booy, and then issues from the chrysalis shell, which it leaves within the burrow. The Wood Leopard Moth, is a very prettily marked insect, though without the least brilliancy of colour. The caterpillar of this ineect keds upon the interior of inany trees, seeming to prefer the wood of the apple, pear, and other fruit-trees. It is a naked, fleshy-looking lara, of aLj-ht yeliovv cilour, and having a double row of black spots upon each segment. Like the Go it-moth, it prepares a cocoon-like cell when it is about to take the pupal form, but the linmg is of stronger materials, cemtnled firmly together with a glutinous substance secreted by ihe.insect. ILe m('th is seldom seen until July, and is tolerably plentiful in some places, appearing to be decidedly local and rather intermittent in ils visits. The family of the Bombycidag includes several insects of inestimable value to mankind, the various siik- producing moths being included in its ranks. The con mon silk-worm is too familiar to need any notice, but as it is not generally known that upwards of forty silk producing moths exist in different parts of the world, a short history will be given of some of thern, together with a figure and a brief dt scription of one of the finest species. AH these in- sects secrete the silk in two large intestine-like vessels in the interior, which contain a gelatinous kind of substance, and become enormously large just before the caterpillar is about to charge into a pupa. Both the silk organs unite in a common tube at the mouth, technically called the spinneret, and through this tube the semi-liquid is ejected. As soon as it comes into contact with air it hardens into that soft, shining fib
