They usually issue from it, in the evening, in procession. One of them is at the head and acts as a guide, then come two, in the next line three, then four, and so on, each line regularly increasing by a unit. They all follow the course of the leader. Each one spins a cocoon, which is placed in contact with that of its neighbour, and mingles the hairs of its body in its tissue. These hairs, as well as those of several other species, are very small and fine, penetrate into the skin, and occasion violent itchings and swellings. The B. pythio.campa is a species analogous to the processionnea. The inhabitants of Madagascar employ the silk of a caterpillar, which also forms large communities. The nest is sometimes three feet in height, and so closely are the cocoons packed in it, that there is no hiatus to be found. A single nest yields five hundred cocoons( 1 ). The third section of the N octurna, that of the PsEuDo-BoMBYoEs, is composed of Lepidoptera, in which, as well as in the following ones, the inferior wings are furnished with a bridle which fixes them to the superior, when at rest. They are then entirely covered by the latter, both being tectiform or horizontal, but with the inner margin overlapped. The proboscis, towards the latter end of the tribe, begins to lengthen, and, in the last subgenera, even scarcely differs from that of other Lepidoptera, except in being somewhat shorter. The antennre are entirely pectinated or serrated, at least in the males. All their caterpillars live on the exterior parts of plants. We will first separate those species in which the proboscis is very short, and nowise adapted for suction. The caterpillars of some, and the greater number, live exposed and do not construct portable dwellings. Of these, some are elongated, furnished with ordinary feet well adapted for walking; the annuli of the body are not soldered above. Sometimes both sexes are provided with wings adapted for flight.
