During the winter we often find on the small twigs of the apple an incomplete belt of a \'ery dark brown, wax- like material. If we ^'^- ^'4- examine this carefully we find it to consist of a very large number of eggs soldered together, from which caterpillars hatch, sometimes be- fore the leaves have started, which at once spin a litvle web or tent in the nearest fork. Here they live in com- pany, moving out from time to time to feed upon the surrounding leaves, and increasing the size of their habita- tion as they grow. The 'tents' form promi- nent and unsightly objects in neglected orchards, and are some- times rather unpleas- antly conspicuous in others that purport to be well kept. When full-grown the cater- pillars abandon the nest, crawl to some convenient shelter in the vicinity, and spin a yellow, rather thin cocoon, which becomes covered with a fine yellow powder. The moth is dull reddish in color, more or less brown-tinged, and the fore-wings have two oblique, pale stripes. 'Hie males are considerably smaller than the females, and as a rule darker in color, tending to have the wing between the lines The American tent-caterpillars, a and b, on the out- side of their tent near the entrance; d, cocoon ; c, egg-mass of an allied species; above all the female moth, Clisiocanipa ainericaiia.
