The grubs are very like caterpillars, and are sometimes called " false caterpillars " ; but a true caterpillar (except in one or two ver}' rare exceptions among foreign species) has never more than sixteen legs, while these " false caterpillars" have more, often as many as twenty-two. They also resemble caterpillars in another way, for the pupa; are enclosed in cocoons. (,)ne interesting Australian species, which feeds on gum-trees, pro- ceeds from a black caterpillar with only six legs. The perfect insect has a blackish head and thorax, with three large yellow spots on the latter, yellowish antenna; and wings, and a green abdomen ; it measures about an inch and a half across the wings, and has knobbed antennae. An allied species, found in Tasmania, is said to tend its young larvae — an unusual habit, except among social insects like bees, wasps, and ants. Among the commonest and the most destructive saw-flies in England are those feeding upon the currant, gooseberr)-, and pear, of which there are several species, measuring about half an inch across the wings. The commonest flies which lay their eggs on the gooseberry and currant are yellow, with the head, antennje, and three long spots on the back black, and the wings transparent, with black veins. The grubs are bluish green, with twenty legs, and numerous black dots ; and several may often be seen on one leaf. The best-known of the Pear Saw-flies is black, with the wings tran
